Abstract

A simple bed urinal is aimed at making the product cheap and mountable on a great variety of common beds, namely simply transforming the common beds to load the product, and aiming at making the total cost of users, and compared with other bed urinals in the related field, the simple bed urinal is very low in price. This patent is divided into two kinds of simple and easy bedridden stool wares according to the difference of the just door mode of opening and falling. The simplest bed pan completely depends on nursing staff to timely nurse patients except for defecation detection; another simple bed pan is additionally provided with an automatic function on the basis of the simplest bed pan: the automatic and quick opening and closing function of the toilet can effectively control the pollution of the toilet, so as to meet the requirements of different poor groups. They have the disadvantage that the bed pan needs to be replaced by a low-cost bed pan in a manual duty mode (the two costs are different). Effective, cheap and pursuing better cost performance is the first problem to be considered by poor consumers. The product has good social effect.

Description

Simple bed pan

Technical Field

The invention is the original application: a bedpan capable of automatically helping defecation, a patent number of 2018109770255 and a divisional application of a patent on 2018, 8 and 26.

The invention relates to a simple bed pan, in particular to a bed pan which sends out signals when a mechanism automatically detects the defecation: a defecation door opened by a caregiver; a drop door is opened by a mechanism. After receiving the signal, the nursing staff carries out nursing work, including manually closing the excrement falling door.

Background

The patent is a bed pan capable of automatically helping defecation of the original patent and a patent number 2018109770255, and a divisional application is proposed on the basis of an original claim 3 deleted when reviewing comments.

The purpose of this patent is to provide a simple and easy bed pan, strives to make the product make cheap to can install on the ordinary bed of very many kinds, just can adorn this product to ordinary bed carries out simple transformation promptly, strives to make user's whole cost, compares other bed pans in the relevant field very low. This patent is divided into two kinds of simple and easy bedridden stool wares according to the difference of the just door mode of opening and falling. The first simplest bed pan completely depends on nursing staff to timely nurse patients except for defecation detection; the second simple bed pan has two automatic functions: the automatic detection urinating and defecating functions and the automatic and quick opening and closing functions. Compared with the simplest bedpan, the simple bedpan only needs to be manually operated and mechanically operated in different simple bedpans, and the share of the simple bedpans is different, namely the simple bedpans and the simple bedpans are obtained by accepting or rejecting different automatic mechanisms in a mother case and then applying the simple bedpans to the design of the simple bedpan without creative labor on the basis of the first simple bedpan and the mother case. More specifically, on the basis of the simplest bed pan (namely the original right 3 in the mother case), a similar scheme is obtained along the idea of the original right 3 in the mother case, but an automatic quick opening and closing function from the mother case is added, so that the bed pan can effectively control the pollution caused by defecation, the performance is improved, and the price is increased. On the basis of the original right 3 in the mother case and the mother case, creative labor is not needed, the scheme conception is as same as the original right 3 bed pan in the mother case, and is a sister article, and the scheme of the mother case is simplified according to the actual needs by adopting a method so as to meet the requirements of economic condition difference groups. It can effectively control the problem of defecation pollution which is a headache. The disadvantages of the bed-pan and the bed-pan are that the bed-pan and the bed-pan are required to be replaced by low cost (the two costs have a certain difference) in a manual watching mode, and the carer is helpless to accumulate points on the premise of using the bed-pan and the bed-pan is low in cost; pursuing better cost performance is a first consideration for poor consumers. "such products would be welcomed by a particular population, producing a good social effect.

The most technically close patents to this patent are: a multifunctional induction nursing bed with publication number CN 202314031U. For simplicity, it is referred to as D1 hereinafter. At first sight D1 feels that it is "virtually" the same as the second latrine pan of the present invention, however, careful study of D1 found that: referring to fig. 11 of D1, there are "urination and defecation sensor heads 59, 60", and only the name of this detector is used in D1, and the principle and structure of the detector are not mentioned, but D1 claims that it can detect urination and how it can recover the detection function after detection. And where in the prior art there is the product "shit and urine induction head" claimed by D1? Through search, in the field of bed pans for automatically detecting defecation, the used defecation detection elements can be summarized into three types in name: one is a faecal sensor as claimed by D1; secondly, a plurality of patents use a humidity sensitive resistor in the infant urine wet alarm; thirdly, a dense tooth-shaped urination and defecation detecting element disclosed in patent publication No. CN 204178521U. While the first type of "faecal and faecal sensor" mentioned above appears in several representative patent documents, it is surprising that they are all referred to by a similar name-the "sensor", and do not disclose the principle and structure of such "sensor". The following demonstrates that all the three urination and defecation detection elements are not suitable for automatically detecting urination and defecation of a bed pan.

1. For example, D1 adopts a 'urine and feces sensor', the triggering mode is image comparison, as long as the urine and feces can be sensed by the urine and feces sensor, the moisture can not affect the recovery detection function of the urine and feces sensor after the urine and feces sensor is washed clean, and whether the urine and feces can be sensed by the urine and feces sensor is doubtful.

Reference to the icons 59, 60 of D1 may refer to such "faecal sensors". It is different from the principle of the humidity sensitive resistor. D1 does not describe the working principle of its detectors (sensors) 59, 60, but is understood only literally. But according to the relevant provisions of patent application document related to disclosure sufficiency: the principles and structures of certain components and parts that are not mentioned but are critical in the patent specification with respect to the subject matter of protection must be products whose principles are well known to those skilled in the art. The principle and structure of this element will be immediately apparent to those skilled in the art by simply seeing it as a name. The known urine and feces "sensor" familiar to those skilled in the art is a commercially available detection element used in urinals and toilets, namely a urine and feces infrared sensor. It belongs to an electromagnetic or photoelectric sensor. The "inductor" claimed by D1 shall belong to such an electromagnetic or photoelectric inductor or otherwise not meet the requirements of the relevant disclosure sufficiency. The widely used infrared sensor for defecation and urination cannot be applied to the automatic detection of defecation and urination of D1, and the reason is that:

let D1 be a well-known infrared sensor for urination and defecation as the inventor guesses-the infrared sensor commonly used in public places for men's urinals and toilets (the latter being commonly used in public toilets in developed countries). Commonly referred to as a "faecal sensor". The principle is as follows: the infrared sensor is used for detecting whether a human body enters or leaves the urine or excrement discharging position of the urinal (which is very easy to do), namely the infrared sensor can sense the arrival and the departure of the human body, the former also signals the mechanism to put a little water to wet the urinal, after the human body leaves, the two infrared sensors both signal, and the driving mechanism flushes the urinal with water. But the working principle of the device is that whether a person gets to the position of relieving the hand is sensed instead of directly sensing the excrement and the urine, so that whether the person relieves the hand is indirectly judged. The reader can make a simple test to confirm that: stand in the urinal urine position that has infrared inductor, or sit on the toilet bowl that has infrared inductor, nevertheless do not know the hand and just leave, these two kinds of toilet bowls certainly can just wash by water as soon as the people leaves. It can be seen that it is a perception of the human body, not a direct perception of whether the human body excretes feces or urine. Again, in FIG. 11 of D1, icons 50, 60 only show where the "sensor" is disclosed to be and the process of triggering. Since the principle of the "sensor" of the icons 50, 60 is not disclosed, nor is the exact size, only the approximate location where it is located, is it known what sensor's principle of operation? How can the sensors 50, 60 know the relevant information "detect the urination and defecation of the patient? The size of the infrared sensor on the market is mostly equivalent to that of a playing card box, and the smallest infrared sensor on the market is equivalent to that of a match box. Such a volume is not suitable for placement in contact with the body at the icons 50, 60, which would otherwise affect patient comfort. If we are not at all right for the right volume. Since the patient is lying in bed all the time, there is no case of coming and leaving, and the infrared sensors on the market are certainly not suitable for this. Because the infrared sensor for detecting the human body cannot stably detect the urine and the feces, particularly, the old who suffers from urine incontinence cannot hold back the urine, the urine can flow out automatically instead of concentrating the urine when the urine volume is not large, at the moment, the urine is much thin and small, the urine is easy to flow along thighs and bedding, independent and anti-interference images are difficult to form, the direction of the image is uncertain, and the image cannot be completely included in an infrared irradiation range (particularly, a male patient has a morning brisk phenomenon, and the urine direction cannot be confirmed) due to the shielding of the human body and the bedding, so that great difficulty is brought to the arrangement of the sensor at any position. The icons 50, 60 of D1 are merely disclosed as to their mounting location. The problem is that the prior urine and feces sensor is used for comparing front and back images when working, when the urine and feces are directly distinguished, a human body can form great interference and position blocking, namely, the position where the urine and the feces are likely to appear can not be comprehensively monitored, so that the urine of a patient is completely drawn, and a detector can not detect the urine. If the sensor is to sense urine, it is difficult to distinguish where the image is urine, who can say it and how can it distinguish whether there is urine or not? The actual situation is that: the prior art does not have a "sensor" that does so. At least such sensors are difficult to "sense" steadily to the point of defecation. Of course, D1 also does not disclose the infrared sensor that i guess it is for, but rather, other "sensors"? This is merely to confirm that the use of existing infrared (or electromagnetic) sensors for urinals has not been suitable if such is the case. In fact, there is no sensor on the market which can detect urine and feces under such circumstances, which is an unsolved problem so far. However, this "sensor" that at least embodies D1 is not allowed for disclosure-apart from this guess, the inventor is not aware of what "sensors" and their principles for relieving the bowels are in the prior art. The lying toilet bowl is different from the toilet bowl and the urinal in that the patient does not enter or leave the periphery of the toilet bowl, so that the important condition of easy induction of human body through 'induction' is lost; therefore, the infrared sensor in the prior art can be confirmed, and the infrared sensor can not be used in a bed pan on a sickbed. D1, however, is not allowed for disclosure, so that one skilled in the art would not be able to duplicate the alleged bowel movement "sensor". Even guessing that there is no existing product available results in no utility for D1. And because even though the concept of "sensor 50, 60" is disclosed in D1, it is assumed that the volume of the sensor is small enough to fit in the location of 50, 60 in D1, fig. 11, whereas the volume of the conventional urinal sensor is too large, which is obviously not feasible.

2. Please refer to a representative related patent two: nursing bed publication No. CN202637328U, hereinafter referred to as D2.

D2, after the patient defecates, the water is used for washing the excrement outlet, the buttocks, the detection element and the like of the patient, then the drying is carried out, so that the purposes of recovering the function of the detection element and drying the water of the washed patient and other parts are achieved, finally, the toilet door is closed, the detection element also recovers the detection function, and the next cycle is entered for waiting for a new period of treating the excrement. Unfortunately, D2 also does not disclose the principle of operation, structure and name of its detector 15. According to other similar patents, the use is of a moisture sensitive resistor, which closely resembles the moisture sensitive resistor, as judged from the position of the D2 detector and its size. We assume that D2 is the use of a moisture sensitive resistor as the urinating and defecating detector. The problems come: in southern areas of China (the areas are very large), the annual average relative humidity in many places is about 80%, which does not refer to mountainous areas and seasides specially, and the average humidity in mountainous areas and seasides is higher. In these places, the humidity is over 95% and reaches about 98% in many times in a year, and even more, in these places, in a year, there are several humid extreme weather, such as the south-returning day, the air humidity is close to saturation, i.e. the relative humidity can reach 99% -100%. When the relative humidity reaches 100% at a certain temperature, the water stops evaporating. Hereinafter, the relative humidity at a certain temperature is referred to as humidity. That is to say, when the air heater of the sickbed sucks air with the humidity close to 100% in the environment at a certain period, heats the air and dries the patient, and because the human body is dried in a short distance and for a long time, the temperature is controlled below 40 ℃, which is high and makes the patient uncomfortable or scald. The quilt has more than 30 degrees originally, so the temperature rise is very limited, and the quilt belongs to low-temperature drying. The physical properties of humidity decrease with increasing temperature, but under such "low temperature" drying conditions, the humidity value decreases only marginally compared to "high temperature" drying, and evaporation stops when saturated humidity is reached quickly at this temperature. This results in a poor or even no drying effect. In this case, it is difficult for the detector of whatever principle to reach the degree of dryness necessary for resumption of detection, with the result that the detector is always in a state of signalling the presence of urination and defecation, so that the automatic bed pan does not close the toilet door. Particularly, the upper limit of the use threshold of the humidity sensitive resistor is that the humidity is less than 95%, and the drying mode is that the humidity required by detectors such as the humidity sensitive resistor and the like is difficult to reach in many times in the south of China, so that the detection function cannot be recovered; it is also more serious that the drying air flow is finally directed to the comforter across the human body, and the warm and humid air flow itself is also directed upward toward the comforter, and the comforter seriously hinders the diffusion of the moisture into the environment. The quilt is forced to turn downwards and collide with the air blown out by the blower, so that a small positive pressure environment is formed in the quilt. Thus, moist air fills any space in the quilt, and a sealing effect is naturally formed due to the upward direction of the fan airflow, that is, a situation of forming a closed container to some extent, so that moisture removal is very slow. The quilt absorbs moisture at the same time. The space is filled by the moist medium in the comforter, which in turn greatly accelerates the conduction of heat (which is a physical characteristic of moist air), and the humidity increases as the temperature in the comforter decreases. When the humidity is high in winter, after the mechanism stops blowing hot air, due to the existence of the 'very wet' humid air in the quilt, heat obtains a medium for rapid transmission, the heat dissipation is obviously accelerated, the temperature in the quilt is rapidly reduced, the humidity value rapidly reaches 100%, and more moisture is condensed along with the temperature reduction. Patients are difficult to sleep in the cold and wet quilts; the wet quilt and the environment inside the quilt also damage the health of the patient. How can such a severely defective product stand on the market? This is also assumed to enable the bedpan to operate automatically in the case of stable automatic detection, and in fact the related art has not succeeded in stable automatic detection. If the detecting element of D2 is negated as a humidity sensitive resistor, there is no detecting element in the prior art having a volume comparable to that of the detector 15 disclosed in D2.

3. If the bare copper wire densed tooth-shaped detection element disclosed in the patent publication No. CN204178521U is used for replacing the detection element disclosed in the patent D2, when the bare copper wire densed tooth-shaped detection element is transversely arranged at a door opening, excrement falling on the densed tooth-shaped detection element is difficult to automatically clean due to the overlarge area of the densed tooth structure, and thus the functional requirement of automatically recovering and detecting again cannot be met. In the detection original element of the patent, after the defecation is detected, a signal is transmitted to a radio mechanism arranged on a bed head through an electric wire, and then the radio mechanism sends out a signal to a guardian. However, it is obvious that this and the use in this patent also propose for the first time in the field that the detecting elements are directly integrated into a single radio detecting element, and the radio design of the car lock is borrowed across the field, and there is an essential difference in use, which is substantially similar to a wired telephone and a wireless telephone, that is, there is a completely different feeling of convenience, and the difference in function is brought.

These automatic detection problems have led to the development of hospital bed toilet products with doors for defecation, with means for washing the buttocks of the patient and detection, which have been presented in some patent documents so far, at least they do not allow a stable detection of the defecation and urination, and they have not been successfully marketed.

From the above three representative related patent analyses (taking into account the various possible detection elements used in the related art), a conclusion is drawn: under the prior art condition, have the door of just using the urine and defecating to detect original paper automated inspection urine and defecating to can resume the patent that detects the function, most (except D1, but D1 is because of disclosing not abundant, and it can't destroy the creativity of this patent) all adopted the mode + stoving of water washing detector, resume the detection function that detects the original paper. Through the above analysis, the conclusion is that: they all encounter patents that fail. Specifically, the method comprises the following steps: in the prior art, in bed pans with a bedpan door in a sickbed, the bed pan with a detection element capable of automatically detecting the defecation has the problem that the defecation cannot be stably detected, thereby causing failure. The detection element of the baby urine wet alarm in the prior art has the common characteristics that: the detection function of the detection original cannot be automatically restored.

On the contrary, the detection mechanism of the invention can stably detect the urination and defecation: please refer to two embodiments of the detecting element for automatically detecting urination, which are described in the present patent, and both of them have been successful. The success of the detection element breaks through the first difficult problem which puzzles the bed pan in the field for a long time, and the simple bed pan of the patent is achieved.

After the defecation detection problem is solved, the purpose of making the simple bed pan can be achieved by two different detection modes. Incidentally: the following documents, except for the first two paragraphs in the "summary of the invention", are the original documents of the duplicate parent application, and refer to the examination opinions of the parent application and related component patents filed on the same date as the parent application, to indicate the existence of the documents in the form of errors for the convenience of understanding.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the two simple bed toilets with different degrees of simplicity are designed to be made into manual and semi-automatic simple bed toilets. I.e. their design is a simplification of the design in the parent application of the present invention to varying degrees, so as to reduce the manufacturing cost and meet the requirements of different poor people.

The invention has the following beneficial effects: the automatic bed pan in the prior art has no practicability, has low overall cost, can accept the functions of the automatic bed pan, meets the basic requirements of poor people and obtains good social benefits. The following is a summary of the invention and the like which duplicate the parent case (hereinafter, "the present invention" means "the present invention" of the parent case ").

The technical problem to be solved by the invention is as follows: for the patients with semi-fuzzy, fuzzy and non-coordinating ability, the utility model provides a toilet which does not depend on the consciousness of the patients, i.e. does not need specific conditions, is in bed and can randomly go to the toilet. Namely, the toilet can be used at any time without any additional condition, or the problem that even the patient with the incontinence can use the toilet in bed can be solved. When the patient defecates at any time, the mechanism automatically responds and assists in defecating in time, so that preliminary treatment is automatically performed, and then the nursing staff performs concentrated subsequent treatment on the defecate and the like discharged into the bedpan at a proper time, so that the nursing staff is prevented from being attended at all weather. The bed pan can be used on nursing sickbeds with other functions, can also be arranged on common reformed wooden beds (of course, the bed can also be made of iron frames, glass fiber reinforced plastics and other materials), can be matched with sickbeds in the prior art and can also be used independently, is suitable for multiple scenes, has high cost performance, and effectively lightens the burden of consumers. The working process of the bed pan is as follows: when the patient urinates or defecates under the buttocks, the quilt and the body, the humidity or smell changes, the urinates or defecates under the buttocks, the trigger mechanism obtains the electric signal, and the signal drives the mechanism to open the urinating door quickly. The opening of the bed pan is preferably circular, and the inner diameter of the opening is not less than the width of the outer edge of the porcelain basin of the toilet. The relative 'large caliber' is to satisfy the condition that when the patient is in the prone position, the defecation dispersion range is large, a sufficient urinal opening is matched with the defecation dispersion range, only the weight of the hip of the patient in the prone position presses the edge of the door opening, and the large caliber defecation hole has little influence on the comfort of the patient. After the mechanism moves the bedpan in place quickly or the excrement falling door moves in two directions quickly, the excrement receiving position of the fixed bedpan is made to be available, and the hip paper pad falls into the bedpan or is scraped to move out of the excrement falling door. And the subsequent defecation is directly carried into the basin, and the toilet mode is started. The monitoring mechanism below the buttocks is preferably of two designs: the utility model provides a detect piece is located buttockss portion below and fixes on the mattress between two legs, survey the pipe and hang the position department between two big legs after opening the door, the gauge head is intraductal portable, the effect is after detecting, the mechanism contracts the gauge head and then is cleaned the gauge head by the rubber class soft circle that the tube head set up, and the accuracy stops in lower extreme opening part, let the warm braw weather and because sheltering from of pipe wall wing, the successor is urinated and defecate and can not be infected with the gauge head once more and trigger signal, when closing the door the gauge head in the mechanism action, rely on elasticity to come back the detection position. The structure is as follows: the two steel semicircular measuring rod cores connected by the two wires are closely spaced by the insulator, so that the two wires are electrically connected with the conducting rings in a staggered mode, and the conducting rings are separated by the plastic rings to form a plurality of spaced signal acquisition rings. When any small part of the urine collecting bag meets the urinate and defecate, a channel is formed to finish signal acquisition; in the design of a wireless monitor, the electrical principle is designed by imitating the automobile remote controller, and the automatic installation mode of the wireless signal detector is as follows: the mechanism uses the front transfer operation similar to the upper hall of a firearm bullet to push out a radio signal detector from the cartridge clip and fall (hang) on a paper pad under the hip to finish the installation of the radio signal detector; the preferred modes for realizing quick door opening are mainly two types: one is that the mechanism pulls open the oblique lock tongue (the time needed is little because of the short stroke), the door rotates around the rotating shaft under the action of the patient's gravity and the door's dead weight, and is opened rapidly; one is that the area of the piston rod cavity of the hydraulic (water) cylinder after utilizing and transforming is very small, its capacity is very small, match the minor liquid inflow and discharge of the electromagnetic water valve of major diameter, the large-traffic water is discharged into the open impounding and irrigates, discharge water through the small-bore drain pipe, thus avoid using the major diameter drain pipe, this design can make the piston rod retract fast, and achieve the goal of opening the door fast; two kinds of modes correspond when closing the door: firstly, the mechanism pushes the door to the proper position and then is automatically locked by the inclined bolt, and then a push rod of the door pushing mechanism immediately returns to give way to the door opening position to prepare for quick door opening; firstly, the hydraulic water cylinder pushes the excrement falling door to vertically upwards to slowly close the door; the toilet door is provided with an annular anti-pinch trigger mechanism, a plurality of micro travel switches connected in parallel are arranged below an annular floating ring, when the toilet door is closed, once limbs of a patient touch the annular floating ring, the ring inclines, the travel switches below the ring are triggered, the mechanism stops closing the door, opens the door and closes the door again, the action is designed according to the elevator door, and when the limbs are moved away, the door can be normally closed; the bed pan consists of a fixed frame part and a movable other part, the frame is fixedly connected with the bed, most of the rest parts are hung on the frame by wheels, and the bed pan is provided with two limit baffles which are positioned at the sides of the buttocks of the patient and provided with adjustable neutral positions so as to meet the requirement of the patient on the activity space. When the patient moving position touches the push plate, if the patient continues to move, the baffle plate is pushed to drive the large part of the bed pan to move on the rack, and the patient moves to one side of the bed along with the action so as to adapt to the moving space required by the patient to be normal (the width of a common sickbed is mostly one meter, and the width capable of moving is close to the magnitude). The reduction of the movement restriction of the patient is to increase the comfort of the patient and increase the 'defending area' for the defecation; when the door is opened, the buttocks slightly fall due to self weight, if the buttocks are inclined at the moment, one side of the buttocks is covered, a pestle is driven into the mortar, and small-range deviation rectifying movement is naturally generated, so that the defecation basin is facilitated; the bedpan can be fixed by the mode of realizing the rapid in-place of the bedpan or the other design of only rapidly translating the door in two directions. Very similar to the mechanism for quick opening the door, there are two preferred designs: a slant lock tongue mechanism is composed of a weighted hammer or a tension spring (the weighted hammer is more stable than the tension spring, and the design of the weighted hammer is preferred), so that the function of quickly moving a bed pan is achieved; a hydraulic cylinder is characterized by that its rod cavity is small in volume, and its rodless cavity is connected with a relatively large-bore electromagnetic water valve, and then matched with external electromagnetic valve, etc., in which the electromagnetic change-over valve is used, and the communication position of original control air channel of commercially-available pneumatic electromagnetic change-over valve and main valve core is artificially blocked, and the hole is drilled outside the original control air channel, and the air channel is communicated with external air source of valve, and in the plate-type connection mode, in addition, the pilot-controlled compressed air can be supplied to said pneumatic electromagnetic change-over valve. The valve body changes the original reversing of compressed air into the reversing of tap water (the corrosion resistance of the aluminum alloy valve body is utilized). But has the capability of retracting the piston rod rapidly. The bed pan detects the defecation of the bed sheet as soon as possible, particularly male patients (the middle and old people are easy to have morning brisk, and then the direction of the urination is towards the navel belt), the urination direction randomness is high, the cloth towel is provided with double bare flexible wires which are fixed at a distance, the double bare flexible wires surround the small belly and the crotch of the patient to form a planar regional property for signal acquisition, the timeliness and the probability of signal acquisition are increased, a driving signal is sent to the bed pan mechanism, and the bed pan mechanism can flow into the bed pan as soon as possible after the bed pan mechanism finishes the guidance of the defecation, so that the pollution is reduced. The following measures are taken for this purpose: the cloth towel with ring-shaped urinating and defecating detecting exposed wire is set on the sheet near the anus to detect urinating and defecating in the area and the trigger mechanism sends out signal. If the detection mechanism is not arranged, the excrement and urine which is 'operated' in the area can pollute a large area of the sheet outside the area, then the excrement and urine flows onto the bedding to trigger the detection mechanism on the bedding, and then the excrement falling door is opened too late, so that more pollution is generated on the bedding. The annular detection mechanism is arranged, so that the drive mechanism opens the urine falling door as soon as possible when the excrement is detected early and a signal is sent. Because the size of the excrement falling door is larger than that of a human body, when the excrement falling door is opened, the buttocks of a person can drop downwards and naturally form a valley shape, and the urine is drained like a funnel to a certain degree, so that the urine flows to the bedpan. The urine which is originally nearly horizontal is guided to spread and is guided to the bedpan as soon as possible after finishing a morning so as to avoid causing greater pollution. Meanwhile, the annular exposed lead is sewn on a piece of cloth towel, when the excrement falling door is opened, the mechanism also lifts the quilt to a certain height, at least five points of the cloth towel are adhered to a hanging belt on the quilt, the center and four sides of the cloth towel are drawn by the cloth towel, a female buckle called a thread gluing belt and a male buckle called a thread gluing belt are arranged on the hanging belt, the lifted quilt draws the cloth towel to be in a tent shape, and the four sides of the cloth towel (which can also be made into a round cloth towel) form a standing skirt edge. The urine which is nearly horizontally jetted and flowed is effectively blocked, so that the urine flows downwards along with the skirt edge (the peripheral size of the skirt edge is larger than the width of a human body), and even if the urine is blocked to flow onto the human body, the urine can flow towards the hip along with the slope potential and finally enters the bedpan because the position of the hip moves downwards to form a valley. The cloth towel is made of an all-cotton oil-resistant and water-repellent fabric. Before the mechanism closes the excrement falling door each time, the cloth towel contacting with the human body is automatically drawn away, and the tail of the drawn cloth towel is provided with a plurality of sections of moisture absorption fat edges made of materials with strong moisture absorption, and the fat edges are dragged along with the cloth towel to wipe the surface of the human body swept away. The novel cloth towel absorbs urine remained on a human body as far as possible, so that the urine is dried more easily by the accompanying hot air, and the phenomenon that the remained undried urine triggers a new annular signal detection device on the cloth towel to generate false alarm is avoided. In the action of rotating the cloth towel rolling barrel to draw out the cloth towel, a root line (which is accompanied with a conducting wire of the plug, the conducting wire is attached to the root line, and the root line bears the force when the plug is pulled out, the structure of the plug is similar to that of an earphone plug) is acted with the cloth towel, and is specially used for pulling out the cloth towel detection original plug 177 to cut off a detection circuit of the cloth towel detection original plug 177, so that the cloth towel detection original plug stops sending signals. When the moisture absorption fat edge of the cloth towel is rolled to be close to the winding drum, the travel switch is touched for a short time to delay and stop the action of cloth towel drawing, the fat edge crosses over the travel switch, the initial state of the travel switch is recovered, the thread gluing belt on the reverse side of the fat edge before stopping is adhered to the thread gluing belt matched with the next cloth towel, and the cloth towel replacement is finished at this time. When the cloth towel is replaced again, the PLC controls the current trend, namely the current does not go through the travel switch pressed by the moisture absorption fertilizer edge, and the winding drum can continue to rotate. The cloth towel is left for the nursing staff to clean and dry for later use. The number of the stacked cloth towels is determined by experience, the replacing action process is like a face changing method, and every time a cloth towel is pulled away from the joint of the hook-and-loop fastener matched with the hanging strip (because the area of the hook-and-loop fastener of the hanging strip is very small, the adhesive force of the cloth towel is much smaller than that of the long hook-and-loop fastener among the cloth towels when the cloth towel is replaced), a 'new face hole' is obtained. A frame type insertion rod is spanned at the center of the bed passing and falling closet door (a steel slipknot and a pulley are arranged in the mechanism, the frame, a steel wire rope and the like are very convenient to disassemble and assemble, and a driving plate without a winding drum is also easy to disassemble and assemble so as not to hinder a patient from getting on or off the bed). Blowing hot air to one side of the hip part and forming a local hot air circulation space so as to be beneficial to removing moisture and drying the detection piece; the mechanism can replace the paper pad below the hip part in each circulation action, the replacement mode of the paper pad is designed by imitating paper extraction of a tissue box, the clamp moved by the mechanism simulates the paper extraction action of hands, and different signal acquisition parts on the mechanism are processed in a related way; the clean cloth towel makes people comfortable; the bedpan is quickly moved to the right position by the mechanism (except the mechanism only provided with the translation door), and is moved away by the mechanism before the door is closed; the bedpan is when accepting the stool and urine, and the running water by the control of electromagnetism water valve is interrupted directly and is washed, and the washing mode adopts two semi-rings shape of symmetry installation can carry out pitch arc operation and wash the head, reaches 'scanning' formula and washes, and it washes the effect: the running speed of the annular water spraying pipe is controlled to a certain extent by debugging a throttle valve on site and applying the throttle speed regulation principle; and modifying the program on the PLC to change the flushing frequency, so that the flushing effect and the flushing quantity are both considered, and the volume requirement of the chamber pot is met; the shape of the bedpan is a reverse truncated cone to facilitate collection of urine and feces; the bedpan is provided with a special moving mechanism (except a translation door) to and fro between a defecation receiving position and a dirt pouring position; before the mechanism closes the door each time, the mechanism acts to enable the flushing mixture to fall into a lower urinal from the bedpan through a pipeline which is much larger than the pipeline of the toilet bowl, so that the toilet bowl is prevented from splashing when moving quickly; the outlet of the toilet bowl is provided with a lateral soft baffle which moves along with the toilet bowl pipe and plays the role of a cover. The odor can be better reduced to be emitted into a room when the toilet is stored in the urinal, and the nursing staff can conveniently pour the toilet; if a large-diameter defecation pipeline is set conditionally, the toilet can be designed to be fully-automatic defecation treatment, the toilet is designed by an electric control switch, and a water return bay well isolates odor, so that the defecation treatment is similar to that of a toilet; after the door is opened, hot air is automatically blown to the buttocks by the heating blower mechanism, flows from one side of the bedpan to the cloth position on the top of the tent and is blown out of the bedpan from the other side of the bedpan to form circulating hot air; it has the following functions: firstly, the patient is prevented from cramping or causing other discomfort and illness due to catching a cold; secondly, the humidity increased due to the dispersion of the excrement is reduced, and the detection original piece is dried to recover the function of detecting the excrement again; the hot blowing system is connected with the frame by a non-metal part to isolate the hot blowing system from different power supplies (voltage) used by other electrical appliances of the toilet stool, so that the electricity safety is better ensured; the electrical appliance part of the mechanism adopts a PLC programmable controller, which can meet the requirements of complex logic control and the like; for conscious people, the toilet can be opened and closed automatically through the keys to realize self-care; the flushing mechanism of the bed pan is preferably designed into a special circular-ring-shaped tubular hydraulic (water) cylinder which is arranged at the upper part of the bed pan in pairs and symmetrically in a stacked mode, the electromagnetic water valve controlled by a PLC supplies water to the flushing mechanism, a hollow-tube semi-arc piston rod with a sealing head moves outside the semi-arc hydraulic (water) cylinder while spraying water from a nozzle positioned at the end of the piston through a water spraying groove under the action of water pressure during water supply, and a pair of symmetrically arranged flushing mechanisms are added together to flush the bed pan in a 360-degree scanning mode. The flushing mode not only achieves no dead angle, but also better utilizes the pressure of tap water when flushing, has better effect than the flushing effect of a toilet bowl, and saves more water. This approach is particularly important for limited chamber pot capacity. The bed pan can also be used for defecation on a multifunctional sickbed in a sitting posture under the condition of adding a toilet ring like a toilet seat, and the bed pan can return to a sitting mode, so that a patient with clear consciousness can comfortably urinate and defecate according to old habits, and multiple functions are realized; if limited by conditions, the bedpan designed by adopting the hydraulic (water) cylinder as the action executing piece can also be powered by a storage battery (the storage battery can be charged by electricity generated by solar energy, small hydropower, small wind power and the like), a high-level water tank is arranged for supplying water, an air cylinder is used for inflating a tire for storing air, the tire provides air for a reversing water valve pilot valve and the like, the bedpan is used in hard conditions such as mountainous areas, grasslands and the like, and the use threshold is low. In addition, fig. 19 is a partial schematic view of the relevant components, in which the toilet-flushing door is in a state before the door is opened, when the two door locks simultaneously actuate the door plate to translate downwards under the action of gravity and the pressure of the patient, and then translate by the force of the weight hammer to open the position of the toilet-flushing hole, and the lower part is a bedpan which can only move transversely along with the mechanism, so that the patient enters a toilet-flushing mode. The door is closed by pushing the flat plate slide block to return by the electric push rod, and the swing rod rotates to close the door. Then the electric push rod (except the push rod for locking the door) returns, and the swing rod also returns to prepare the door opening condition. In order to save cost, only an automatic detection mechanism is used, when the mechanism automatically detects that a sick person and a disabled person lie on a bed to relieve the bowels randomly, an audible and visual alarm is sent out according to an electric signal, a nursing person immediately arrives at the bedside after receiving the alarm, a defecation door which is not smaller than the width size of the outer edge of a defecation ring of a toilet bowl is manually opened, the toilet bowl is put in, the sick person and the disabled person enter a defecation mode in a lying position, the toilet bowl is withdrawn when the defecation is finished according to experience or the obtained indication of the patient, the defecation door is closed, the patient finishes a defecation process, and the process can be repeated. It requires the caregiver to be on standby at all times, but is also superior to many product performances.

Has the beneficial effects that:

the invention has the following beneficial effects: the patient gets the automatic and fully pollution-controllable bed-lying toilet service, and the pollution caused by defecation is little. The bed toilet has unprecedented sanitary and comfortable experience; the bedpan can move along with the transverse movement of the patient, so that the limitation on the patient is reduced, the pain of the patient lying in bed for a long time is reduced as much as possible, and the 'defense range' is expanded; patient cooperation and attendance of nursing personnel are not needed, the operation is safe and stable, and the total nursing cost is the lowest in various modes; the disposable diaper is not required to be treated, is not influenced by climate, completely gets rid of the diaper, greatly improves the nursing environment, and greatly reduces the nursing labor intensity (particularly avoids the heavy physical labor for lifting the hip of a patient), so that the scale of nursing alternative population is greatly increased, particularly the automatic defecation assisting and nursing labor intensity is greatly reduced, the mate of an old patient can mostly undertake or assist the work under the temporary assistance of people, and the ideal situation that the old people's age is mutually supported to the old' is continued; economic and mental burdens of children are reduced, the time spent in home-care is greatly prolonged, benefits of all families are remarkable, and social burdens are reduced; the harmony of the patient is increased, the heavy physical and psychological loads of the family members are released, and the worries of the family members after the family members are solved; the bedsore is effectively reduced, or the patient with the bedsore obtains the best treatment environment; the odor in the room is effectively restrained, and the air quality in the room is greatly improved. The quilt uncovering operation is greatly reduced, so that the cold, illness and cramping are reduced; the clean and graceful treatment mode maintains the dignity of the patient and enables the family members of the patient to be greatly soothed; effectively preventing the old people who abuse in extreme situations from happening and indirectly prolonging the service life of the patient; humanistic and humanistic care are brought to the best attention of the technology.

Detailed Description

Description of the drawings: because the drawings are small in size, details of each part are difficult to clearly express, structures of partial related parts are only expressed in many drawings, and detailed drawings of installation and connection of a rack and the like are omitted. Can be understood in connection with multiple figures.

When the patient urinates and defecates, the part below 123 of the buttocks, the part below 173 of the quilt and the part above the body in the peripheral area taking the crotch as the center change the local humidity or smell because of urine or excrement under the buttocks, and a monitoring mechanism is arranged at the local position, and the change triggers a monitoring element of the mechanism to obtain an electric signal. Because the toilet is conductive or has some gas in its smell that can be easily detected. The monitoring elements may thus be two conductors in close proximity but separated by an insulator, or for a gas detector. Once the toilet bowl has served as an electrical bridge, both wires are electrically connected, or some odor is detected in the bowl, the mechanism completes the task of acquiring a signal. The signal collection can be performed by a defecation detection element consisting of an electronic humidity sensitive element in the prior art or a monitoring system consisting of a gas detector capable of detecting defecation, such as detectors for methane, ammonia gas and the like (all belong to the prior art and are omitted). But they are not considered as preferred because: firstly, the detection of an original and an electronic product thereof is too complex, compared with the situation that faults are likely to increase, signals which can be directly obtained are converted unnecessarily, and timeliness is poor; or a plurality of gas detectors (generally detecting methane, ammonia gas and the like) which are difficult to distinguish the fart from the stool, thereby causing 'fart removing of trousers'; or the continuous detection is triggered by gas which is not cleaned up at the previous time, and false alarm is made. However, it is not always necessary to specifically eliminate the adverse factors by intensive studies. Preferably, the signal acquisition element: there are two different detection original components in buttock below and crotch top. Wherein the monitoring mechanism below the buttocks has two kinds of designs in turn preferentially: a detection piece is located buttockss portion below and is fixed on mattress 122 between two legs, a plurality of conducting rings are separated by insulating cushions, the dress is on conducting ring electricity connection boss 133, form the no dead angle detection mechanism that the multiple rings are separated, plastics gauge head branch pipe hangs the position department between two big legs after the door is opened, the gauge head is intraductal portable, the effect is after detecting, the mechanism contracts the gauge head and then is cleaned the gauge head by the rubber class flexible ring that the tube head set up, and accurate stop is in lower extreme opening part (it is accurate location through fixed range regulating plate 143 in the fixed range traction mechanism, in order to ensure to weather the effect), let the warm braw weather and because the sheltering from of pipe wall and pipe wall wing 126, the later just can not be stained with the gauge head again and trigger signal, when closing the door the gauge head in the mechanism action, rely on elasticity to come back to detect the position again. The structure is as follows: the two wire-connected steel (steel is needed to ensure the strength because the measuring rod core is thin) semicircular measuring rod cores are closely spaced by an insulator, so that the two wires are in staggered electric connection with the conducting rings, and the conducting rings are spaced by plastic rings to form a plurality of spaced signal acquisition rings. When any small part of the urine collecting bag meets the urinate and defecate, a channel is formed to finish signal acquisition; a wireless monitoring original piece slightly improves the automobile lock remote controller technology by the design of an automobile lock remote controller: the circuit only needs to change a hand key switch into a mode that a plurality of pairs of strip-shaped touch detection lines 151 distributed outside the cylinder are arranged (the button is cancelled), the touch detection lines are triggered by defecation, and the circuit can be controlled (an electronic time relay is arranged in the circuit, the circuit can be controlled to be disconnected, and a manual button can restore a path) to trigger for one second or two seconds, then the radio signal detector stops transmitting the radio signal, and the function of the radio signal detector stops. It falls into the bedpan 3 along with the defecation and the defecation, then enters the bedpan 11, and then is picked up by the nursing worker for cleaning and drying, and then the reset key 152 is pressed by the hand to recover the signal acquisition function for standby. The mechanism automatically replaces a new radio signal detector each time (a plurality of radio signal detectors 15 are available, one at a time automatically added in conjunction with the door closing action.) the radio signal detector is automatically installed: by means of the structural design of the gun cartridge holder 16, a plurality of radio signal detectors 15 are pressed into the cartridge holder like bullets, each time the mechanism works like the front transfer of a firearm bullet going to the hall, one radio signal detector is pushed out from the cartridge holder 16 and falls (hangs) on a paper pad below the hip to complete the installation of the original; crotch portion top detection original paper: it is made up of two bare copper wires 173 separated and fixed in a ring shape by short distance of insulator. They are sewed on the cloth towel 17, and are positioned under the quilt in the form of circular ring around the crotch of patient, and are combined with detection component 133 or radio signal detector 15 under the buttocks to form parallel-connected three-dimensional monitoring system, and any local part of detection component can be stained by urine and urine, and can trigger mechanism to give out signal. The cloth towel 17 is connected with at least five points 171 on the sling on the quilt, which holds the center and four sides of the cloth towel, the sling is provided with a female button and a male button called as thread gluing tapes, and the cloth towel is connected with a piece of cloth towel made of 'all-cotton oil-resistant and water-repellent fabric'. Before the mechanism closes the excrement falling door each time, the cloth towel 17 contacting with the human body is automatically drawn away, and the tail part of the drawn cloth towel is provided with a plurality of sections of moisture absorption fat edges 176 made of materials with strong moisture absorption, and the fat edges are dragged along with the cloth towel to wipe the surface of the human body which is swept out. The urine residual on the human body is sucked away as far as possible, so that the urine and the stool are easier to dry by the accompanying hot air, and the false alarm caused by the weak trigger signal of the non-dried urine and the stool is prevented from being residual later. In the action of drawing out the cloth towel from the cloth towel rolling barrel, a root line (which is accompanied with a conducting wire of the plug, the conducting wire is attached to the root line, and the root line bears the force when the plug is pulled out, the structure of the plug is similar to that of an earphone plug) is specially used for pulling down the cloth towel detection original plug 177 to cut off a detection circuit of the cloth towel detection original plug 177 to stop sending a signal along with the action of the cloth towel. When the moisture absorption fat edge 176 of the cloth towel is rolled to be close to the winding drum, the travel switch is touched to stop the cloth towel drawing action, and the cloth towel replacement is finished once. When the cloth towel is replaced again, the PLC controls the electricity to move, and the reel can continue to rotate without going through the travel switch pressed by the moisture absorption fertilizer edge. The cloth towel is left for the nursing staff to clean and dry for later use. The number of the stacked cloth towels is determined by experience, the replacing action process is like a face changing method, and every time a cloth towel is pulled away from the joint of the hook-and-loop fastener matched with the hanging strip (because the hook-and-loop fastener of the hanging strip has small area, the adhesive force of the cloth towel is far smaller than that of the long hook-and-loop fastener 172 between the cloth towels) to obtain a new face hole. The center of the falling-down door on the bed spans a frame type insertion rod (a steel slipknot is arranged in the mechanism, and the frame and a steel wire rope are both convenient to disassemble and assemble so as not to hinder a patient from going to and from the bed), a lifting hook is arranged at the center of the rod, when the falling-down door is opened, the mechanism drives the lifting hook to rise, and a quilt on the crotch of the patient is lifted to a proper height under the support of the frame type insertion rod. The cloth towel in the quilt is also hung by being pulled by the sticking buckle belt, and is in a tent shape. The cloth towel has good water repellency in a short time, the stacked cloth towel and the quilt are isolated from being infected with urine, the vertical group edges of the tent-shaped cloth towel can more effectively block the urine, the diffusion range of the tent-shaped cloth towel is reduced, and the tent-shaped cloth towel can flow downwards as soon as possible to enter the bedpan 3. The area of the hip pad which is positioned on the belly and the crotch cover forms a three-dimensional defecation electric signal triggering area. The timeliness of signal acquisition is ensured, the mechanism becomes a ring for quick response, and the quick action of the mechanism is favorable for reducing pollution and successfully assisting defecation. The opening of the bed pan is preferably circular, and the inner diameter of the opening is not less than the width of the outer edge of the porcelain basin of the toilet. This is because the distribution of the lying position toilet stool is large, and a large enough urinal opening is necessary. This is the same as if the shot of the astigmatic projectile gun could not be a 10-ring shot, one for fine aiming and one for coarse aiming, so that the latter must be enlarged by the "10-ring" circle. Still because the people lies when urinating and defecating, the buttock is unsettled, below the waist, the power is born in thigh three places, and the pressure sum buttock when people's toilet seat born is far less than, and more dispersion moreover: one is the hip weight and one is the weight of almost the entire person. Due to the large difference in force between the two, the larger door opening 121 has little practical effect on patient comfort and may be more comfortable than (with respect to a toilet). And because the patient can not aim at the undersized defecation hole every time, the relatively larger defecation hole can effectively prevent the defecation from polluting the hole edge. In order to substantially reduce the position limitation on the patient, a horizontal moving mechanism 02 of the bed pan is additionally arranged. The bed pan is designed into three major parts, namely a pan foundation frame 1, a pan moving body and other fixed parts, wherein the pan moving body is hung on the pan foundation frame 1 through pulleys: when the patient moves transversely, the baffle plate 212 can be pushed vertically by the buttocks of the patient to carry out limited movement towards the bedside together with the movable body of the whole toilet stool so as to reduce the limitation on the moving area of the patient (the patient with the moving capability always carries out disordered left and right movement on the bed, the size of the toilet falling door is limited by the space required by a bed mechanism, and when the patient without the function deviates from the center of the bed, the toilet stool can pollute the bed cushion and the like), so that the patient feels the movable limitation on the movable area and the fixed baffle plate, and the toilet stool is completely different but almost the same as the toilet stool. Thereby not only meeting the requirements for preventing pollution, but also reducing the restriction on the activity space of the patient. Not only relieves the pain caused by long-term lying in bed, but also enlarges the 'defense range' for relieving the bowels. The turning motion of the patient for preventing the bedsore is not hindered, and the comfort degree of the turning motion is acceptable for the patient. The pollution prevention effect produced by the design is of great importance in the automatic and reliable operation of, for example, a toilet. Due to the increased size of the hole 121 compared to a toilet bowl, and the unattended operation, the door pinch prevention mechanism 904 must be concerned: an annular anti-pinch mechanism 904 is provided on the periphery of the upper face of the drop door panel. If foreign matters touch the annular travel switch touch plate at the edge of the door plate, the door plate is inclined, the parallel travel switches below the door plate have at least one action to send a signal, the door is closed under the control of the PLC, the door is stopped and opened, the door is opened like an elevator door and repeatedly opened and closed, and the door is closed until the foreign matters are removed. Thus, the limb of the patient is not pressed when the door is closed, and the safety measure is necessary and is particularly important for unconscious patients. And the contact surface between the edge of the mattress quilt on the door panel and the hole of the mattress quilt on the bed is a conical surface matching structure, so that the mattress quilt can be squeezed tightly without air leakage when the door is closed, thereby effectively keeping warm. The door opening action is characterized by different speed from the prior art, and the pursuit of rapidness is to greatly reduce the pollution of bed clothes caused by defecation and urination and ensure the satisfaction of consumers. The door opening mechanism is preferably designed in the following two ways: one is that the door opening design is closely related to the door closing action, so the door closing design is introduced firstly, and the common automatic door locking design is adopted, and a patient is supported by an inclined bolt instead of a push rod in the prior art. In the prior art, the door is opened and closed by a push rod directly, the speed of the door is the running speed of the push rod, and the speed of an electric push rod is very slow. In order to achieve the functions of opening the door and positioning the bedpan quickly (the whole door opening process in the prior art is about 5 seconds as fast as possible, and the speed of the invention is more than 3 times higher than that of the door opening process in order to meet the requirement of minimizing pollution), the push rod head and the push rod head 901 are preferably matched with a pestle and a mortar, so that the push rod head and the door can be separated after the door is locked and can be mutually restricted when the door is closed, and the door opening and closing actions are completed. After the oblique lock tongue locks the door, the push rod 910 is retracted immediately and stays at a specific position, so that the push rod 910 gives way to the door opening passage. When the door is opened rapidly, the inclined bolt is pulled by another electric push rod 908, the distance for pulling the inclined bolt is very short, the natural time is very short, and after the door loses the support of the inclined bolt suddenly, the rotating rod rotates in the rotating bracket 909 under the action of the gravity of the patient and the self weight of the door, and the door is opened rapidly. When the door is closed, a third electric push rod (similar to a paper clamping mechanism because the picture width is limited and matched with a traction heavy hammer or a tension spring is not shown) overcomes the tension spring force to push the bed pan back to the starting position, the heavy hammer rises or the tension spring is tensioned, meanwhile, the bedpan frame is locked by another inclined bolt, and then the third electric push rod returns immediately to complete the preparation work before the door is opened next time. There is yet another form of evolution: it is different in that it is a double door 107, two shafts are connected by chain transmission and change the rotation direction by gear 104, the basic structure is mostly the same as that of single shaft. The design is beneficial to reducing the height of the bed, so that a patient can get on or off the bed conveniently, and different structural details of the bed are omitted from the conventional way. The executing element of the "pushing door" preferably selects the electric push rod 101 or the hydraulic (water) cylinder 709. The electric push rod is a common universal part, and needless to say; the other is a special hydraulic (water) cylinder 709 which is modified by a cylinder and is used as an execution element to replace the electric push rod 101 (the power source of the electric push rod is shown in the following) to finish the actions, and other designs are not changed; a hydraulic (water) cylinder 709 utilizes a rod cavity piston with small area, namely small volume, even in rapid movement, the water inlet flow of the rod cavity is small, and a rodless cavity outlet (except a connector with 15 mm of drift diameter used when a piston rod extends out is connected with an electromagnetic reversing water valve) is matched to connect a large-caliber electromagnetic water valve 704 and an open water storage tank 706, wherein the water storage tank is higher than the bottom of the hydraulic (water) cylinder 709, so that air is prevented from entering the lower part of the hydraulic (water) cylinder 709 and a pipeline, and air can not enter the water cylinder, so that the water cylinder can move to crawl later, and the position of the piston rod can not be kept for a long time. The outlet of the piston cavity matched with the small water storage tank is connected with the small water storage tank, the short-time drainage capacity which is suddenly large is buffered, water can be supplied and drained by a water inlet and outlet pipe with the diameter of 15 mm, and the piston rod of the hydraulic (water) cylinder 709 is quickly retracted, so that a large-diameter drainage pipe is not needed after the water storage tank is filled, and the function of quickly opening a door or moving a bed pan is formed; the electric push rod can replace the electric push rod, the retraction of the piston rod after the door is closed is not needed, the door locking design of the inclined lock tongue is not needed, and the piston rod directly and rapidly retracts to open the door. In addition, the design does not have a traditional hydraulic pump, tap water is used as a power source to drive a special hydraulic (water) cylinder 709 to complete the action of the push rod, the process is silent, the design is particularly important for patients who feel uncomfortable with mechanical sound, and the influence on the rest of the patients is reduced. The toilet door is connected to the bed frame without a rotating shaft, and a hydraulic (water) cylinder is arranged below the toilet door and directly drives the toilet door to vertically move up and down under the guidance of a piston, so that the rapid door opening and the slow door closing are realized. When the door is closed, the third electric push rod or the hydraulic (water) cylinder overcomes the force of the heavy hammer or the force of the tension spring to pull the bedpan back to the starting position, the heavy hammer rises or the tension spring is tensioned, the bedpan frame is locked by the inclined bolt, and then the third electric push rod returns instantly (the return of the bedpan is completed by the heavy hammer or the tension spring) to complete the preparation work before the door is opened next time. The hydraulic (water) cylinder is transformed on the basis of a standard cylinder, and the existing cylinder is made into a special hydraulic (water) cylinder through transformation: the area of the piston of the rod cavity and the rodless cavity of the cylinder body is greatly different (namely the diameter of the piston rod is close to the inner diameter of the cylinder); the piston rod 707 is made of stainless steel; the piston, the cylinder body and two ends of the cylinder are made of aluminum alloy originally, and the cylinder has corrosion resistance, is rated to bear 6 kilograms per square centimeter originally, and has surplus to bear tap water pressure; the rodless cavity is connected into a large (relative) diameter electromagnetic water valve 704; thus, the special hydraulic "water" cylinder 709 is driven to work by using tap water (which is easily done by only arranging two pipelines with 4-minute diameter for water inlet and water outlet in a room). Meanwhile, a standard pneumatic element, namely a pilot type pneumatic electromagnetic reversing valve (a reversing valve with a larger drift diameter than 801 is improved, but the structures of the reversing valve are the same, and the transformation difficulty of the small-drift-diameter valve for a door locking cylinder is more difficult due to small size, so the transformation of the small-drift-diameter valve is used as a description) is matched with the small-drift-diameter valve: the deepest part of the air passage 808 hole in the main valve body of the pneumatic electromagnetic directional valve is blocked artificially, a hole 807 is drilled outside the original control air passage, the air passage 808 and an air source outside the valve are communicated through a new hole 807, and the plate type connection mode is as follows: an O-shaped sealing ring is added on the joint 806, and the pneumatic electromagnetic directional valve is additionally arranged under the action of the pressure plate 805 to supply pilot control compressed air. The lower limit of the pressure required by the valve is slightly higher (0.1 Mp) by the pressure reducing valve for air supply, and the air is supplied intermittently and only by the pilot control part, so the air consumption is very little. Fig. 8 is a modification example of a small two-position five-way valve (for example, for opening a latch) with a 6 mm diameter. The pressure reducing valve can be mounted on one or two tires for air supply, one-time inflation can be carried out for a long time, frequent inflation is not needed, and due to the fact that the inflation workload is not large, noise is avoided and the occupied space is small when the tire inflation device is used. Thus, a 'hydraulic (water) and pneumatic combined design' valve 801 is changed (except for a control part, a water valve is changed from a gas valve, and a pneumatic valve originally is made of aluminum alloy and has corrosion resistance, so that the problem of using tap water as a transmission medium is solved). The air pressure meter is used for reading to determine whether the tire needs to be inflated (a vehicle-mounted air pump can be used for inflating easily, and the tire can be inflated manually when the vehicle-mounted air pump is not in a condition). Therefore, the whole site of the 'hydraulic (water) and pneumatic combined design' has no common oil pump, air pump, motor and the like, especially the 'factory-like' facilities, and the mechanisms only need to use safe voltage. Although the transmission medium is not traditional hydraulic oil, the mechanism is affected, the working conditions of low pressure (tap water pressure) and low load are greatly different from the working conditions corresponding to common hydraulic oil, and therefore, the use requirement can be met even if the transmission medium is water. Even if the service life of the sealing element is reduced, the sealing element is cheap to replace (even if the whole part is replaced, the sealing element is not expensive), the necessary requirements of silence, safety, low price, reliability and convenience are met, and oil stains and the operation noise of a compressed air pump which are inevitable for a common hydraulic system do not exist on the site. Even in a difficult place such as a country without running water, the necessary lifting force can be obtained by enlarging the cylinder diameter, water is supplied by a roof water tank, and tires are inflated manually. The door sill is greatly reduced in use and has a large popularization range. The invention breaks the conventional way, such as the animal's "four unlike", which is just about the trouble? The problem is solved and the beneficial effect is achieved. The bedpan moving mechanism is designed into two types: one is that under the action of a heavy hammer or a tension spring, a lock tongue is quickly moved to the right position by the heavy hammer or the tension spring after being unlocked, and when the lock tongue is about to be in the right position, a buffer mechanism buffers the lock tongue, so that the lock tongue is quickly moved. The return before the door is closed depends on a special electric push rod, overcomes the force of a heavy hammer or a pull spring, moves in place and is automatically locked by an inclined bolt, and then the push rod returns to prevent the bedpan from rapidly moving next time; one is to use the hydraulic "water" cylinder 206 modified by cylinder and add the water storage function of the water return tank 210, and to use the area difference between the rod cavity and the rodless cavity is very large, and the two-end buffer design of the general cylinder is reserved, to realize the quick moving of the bedpan in place without impact when opening the door (slow moving when closing the door). Of course, the valve opening mechanism also needs to be matched with an improved electromagnetic directional valve with the diameter larger than that of the electromagnetic directional valve 801, and the like, so that the action can be realized. In order to reduce the odor of the excrement, the following three measures are adopted, namely, a flushing mechanism is arranged at the whole upper edge of the bedpan 3, water is sprayed 185 through an electromagnetic valve, and flushing is carried out once or more times (which can be set on a PLC) before the door is closed and opened every time. The flushing mechanism has the structural design that: the appearance and the movement are similar to the old bicycle lock, the bolt is replaced by a special semi-circular hollow piston called a flushing movable semi-ring 183, the appearance is similar, the piston is called because the movement form and the structure of the piston are similar to those of a piston of a hydraulic cylinder, and the difference is that the center lines of a cylinder barrel and the piston of the piston are always curved and the piston is solid and hollow. And the head of the plunger has a nozzle 185 that extends through a slot 187 in the outer tube, toward the upper wall of the bowl. When the electromagnetic water valve supplies the tap water into the cylinder, the special piston 183 is pushed by the water to overcome the elasticity of the tension spring 184, moves in the arc tube with the groove, and sprays water to the upper wall of the bedpan through the groove 187 on the guide tube, which is synthesized as radar scanning, continuously and sequentially carries out full-coverage water-spraying cleaning without dead angles on the wall of the bedpan 3, and the formed mixture falls in the pipeline at the bottom of the bedpan. A stainless steel tension spring 184 is mounted inside the hollow rod of the arcuate piston, with one end attached to the bottom end cap 181 of the arcuate cylinder and the other end attached to the spray tip end 189 of the hollow rod of the piston, and is elongated as the piston extends, providing the return force for the piston. And just let the anus mouth of people be located the center of bedpan 3 export in the design, bedpan export pipe diameter is far more than the toilet bowl for excrement falls into the bedpan export basically, and less glue on the basin wall to reduce the bath volume, the bath to the basin wall is mainly in order to wash the urine, just so easily has much more. Since there is a lot of mixture entering the chamber pot 11 after several successive receptions, it cannot use as much water at one time as a toilet bowl, otherwise it takes too much time to pour the pot manually. The retraction of the piston 183 is that after the electromagnetic water valve is cut off, the electromagnetic water valve is pulled by the tension spring to retract, and the residual water in the piston is extruded from the water jet. Each set of scanning type flushing mechanism 18 can only flush half of the wall of the bedpan, and the other half of the flushing mechanism is simultaneously flushed by the same scanning type flushing mechanism 18 which is symmetrically arranged along the traveling direction of the piston (can be controlled by the same electromagnetic water valve), so that the design well meets the requirements of water saving and high efficiency, and is exactly matched with the round bedpan 3; 2. the bedpan is that an inverted round platform shape is hopper-shaped, and its export diameter conditional design is bigger than toilet bowl export diameter, reduces outer row resistance and makes the defecation kettle of row wash away power bigger on one hand, has increaseed the capacity in order to adapt to the ability of holding filth on the other hand. The lower port has a flapper with a seal 304 that stops before moving when the bowl moves into a stop position, where the flapper at the bowl outlet is fully opened and the toilet mixture drains by gravity into the urinal 11. The flushing water and the excrement and urine flow into the urinating and defecating pot. Water and excrement are mixed in the kettle, so that odor emission is reduced, and the excrement cannot be splashed out due to the sloshing of the bedpan when the empty bedpan moves quickly. When the chamber pot is poured, the chamber pot is pulled out to be poured out separately after manually confirming whether the chamber pot needs to be replenished for flushing or washing. Technically, the subsequent automatic flushing of the bedpan is realized without difficulty, and the full automation of the toilet is realized. The choices that can be made are: if a large-diameter pipeline for defecation is convenient to install in a ward or at home, flushing can be controlled by the electromagnetic valve (timing is started by the door opening time, and a time is set on the PLC electric appliance to enable the electromagnetic water valve to be electrified for flushing), so that a bedpan with a flushing function (which belongs to the conventional technology and is omitted here) can be obtained, the automation of the whole process is realized, and odor is effectively eliminated by means of a proper amount of flushing water; at the beginning of building a house, no large-diameter defecation pipelines are arranged in the house, and the inconvenience is caused by newly adding (later dismantling) large-diameter defecation pipelines. Hospitals are well suited to such fully automated designs because of their existing conditions and without concern for removal a day in the future. This more ideal design is fully applicable. From the practical consideration, the manual subsequent treatment mode (reverse toilet) is selected more, and the design of the reverse toilet is difficult to avoid certain odor due to the limited water consumption and other reasons.

In order to make the toilet-like device smoothly run, some special auxiliary mechanisms with additional technical characteristics are matched to perfect the design.

The warm air is provided by the heating facility (as the heating facility, except for the last nozzle 302, may be selected from conventional related products, which are not described in detail herein, nor illustrated). The patient may have leg cramps and great pain in the case of slight cold due to weakness (most elderly) or lack of calcium. Therefore, as long as the patient is not very dry, hot air is blown from the bottom, the heat is adjustable, and the body of the patient can be sufficiently insulated. Greatly reducing the possibility of cramp caused by catching cold. The hot air also has the functions of drying the detection element to recover the function of detection again and keeping the skin of the patient dry as necessary. For the reason that the patient is too hot and does not need hot air, the heating system can be selectively closed, but a proper amount of air blowing is still necessary for reducing the humidity and drying the detection head and the skin of the patient. The whole heating mechanism is a relatively independent mechanism (no metal is directly connected with all parts of a toilet and a bed body to ensure that the heating facility is insulated from other objects, and the heating mechanism independently uses commercial power), and the whole heating mechanism is mainly separated from low-voltage direct current power used by a toilet main body and a bed so as to ensure the power utilization safety. The paper pad can be replaced when the mechanism acts every time, which can prevent and reduce the pollution of the beddings caused by defecation and does not influence the comfort of patients. Certainly, the cotton cloth can be used for replacing paper, so that the patient feels more comfortable, but if the cotton cloth is repeatedly used, a lot of workload can be increased, and the corresponding mechanisms of the cotton cloth and the cloth are basically the same. The mode of mechanism's paper change is that imitates a articles for daily use box paper extraction design: when the paper is taken out from the special box paper, the front paper brings out the back paper, and a part of the taken-out paper falls on the supporting claw 502, but the hand is only pulled out to be changed into the clamp 4 which is automatically opened and closed. The automatic opening and closing of the clamp is realized by that a special longitudinal bedpan moving frame 2 is driven by double lock tongues, and a mechanism with a clamp 4 is driven to different positions to touch a specific roller: the clip is moved by the mechanism bedpan simultaneously often, through opening the effect of pressing from both sides gyro wheel 406 and inclined plane 408 when pressing from both sides the paper position, accomplish the automation of clip and open and shut, press from both sides behind the paper, another hypotenuse of two pawls of integrative dislocation two-way hypotenuse just is compressed down by the gyro wheel, do not have the stopping of pawl (two spring bolts), the clip is under the traction of weight 401 (with the weight and not need the elasticity original paper because the weight work is the most stable), get back to initial position, and touch the clip and open gyro wheel 603 and open the clip, thereby the paper has been released, and realize automatic clamp and get, take out the paper and finally cover the action on falling the just door 903. The mechanism principle of changing paper of different falling excrement door embodiments is the same, and the structure has some differences. In order to save cost, a simple design is as follows: only use the automatic checkout mechanism, when the mechanism detects automatically that sick, disabled person lies in bed and urinates randomly, send the audible and visual alarm with this signal of telecommunication, the nursing staff arrives the bedside immediately after receiving the warning, and the manual stool door that falls that is not less than the outer width size of toilet seat circle is opened to the manual, puts the bedpan in place. Because most of the work is handled manually each time, the bedpan is very simple and low in height, a four-link bedpan feeding and withdrawing mechanism can be manufactured, and the operation is simple and practical. The patient and the disabled enter the toilet using mode in a prone position, the patient withdraws the bedpan when the toilet using is finished according to experience or the obtained indication of the patient, closes the toilet falling door, completes the toilet using process once, and can repeat the process. The disadvantages are also evident: the nursing machine needs nursing staff to be in a standby state all the time, the labor intensity is also common, but the performance of the nursing machine is also superior to that of a plurality of products on the market at present.
