Description

This is a device and equipment that automatically handles excrement for people who are bedridden or unable to walk on their own due to illness, etc., and have difficulty in defecation and urination. , A device that treats excrement to suppress the growth of germs, and a fitting that wraps around the excretory part and the surrounding area to reliably prevent excrement leakage and hygienically and smoothly removes the excrement and cleans the surrounding area It is about.

Conventionally, an apparatus for processing and collecting excreta for people who cannot walk by themselves, such as elderly people, illnesses, and disabilities, has been proposed and put into practical use.
In the collection, a wearing tool is attached to the lower abdomen, the excrement flowing down between the wearing tool and the lower back is sucked, and on the other hand, the excrement adhering to the washing water is washed away.
In order to collect excreta, it is necessary to improve the adhesion between the wearing tool and the human body so that sewage and odor do not leak outside.
However, in order to wash the excrement stuck to the body, attach a fixed-type wearing device that can secure a certain gap from the body and wash it with strong water pressure, or excrement is excreted directly into the excrement inhalation port of the wearing device. The shape was made.
In the former case, if the vertical direction of the wearing tool is not within a certain range, side leakage and suction failure will occur.
The latter causes sticking to the body and sticking when the excretion position and the suction port mounting position are misaligned.

It is an object to solve various problems of the prior art by removing a foul odor from a wearing tool having a structure adapted to the human body and the collected excrement.
That is, it is possible to provide a wearable device that can be worn at all times, is soft, can be turned over freely, and does not cause burden on the wearer and does not cause excrement leakage.

Another challenge is to remove the odor of excrement collected and collected from the wearing equipment and to suppress the proliferation of bacteria in the excrement, so that the odor can be used only comfortably in the device, and it is a sanitary excrement collection process. To provide an apparatus.

This apparatus is divided into an attachment device (2) for aspirating and collecting excrement by attaching it to the body shown in FIG. 2, and a collection processing means (1) for collecting and storing the excrement shown in FIG. It consists of bulls and tubes.
The mounting tool (2) is made of a multilayer plastic sheet that does not allow water to pass through, and is mounted on the lower back.
As shown in FIG. 3, the wearing tool is attached to a sensor for detecting excretion, a suction port (10) for sucking excrement, an air supply nozzle (69) for blowing out warm air corresponding to the suction, a lumbar region and a fitting tool after excretion. A washing nozzle (68) for washing out the waste is attached.

One of the sensors for detecting excretion is attached to a position where excrement is excreted by a sensor (66) for detecting temperature. The stool is attached to the stool, the urine is attached to the urine, and the man and woman are attached to different positions. The sensor is a non-contact type that does not directly contact the body.
The other one is a sensor (67) that detects odors and is attached to a position where it does not come into direct contact with excreta.
The timing of excretion is recognized with an increase in temperature. The temperature of the wearing equipment is lower than the body temperature. The excrement is the same as the body temperature, and when the excrement comes into contact with the sensor, the measured value increases several times. It takes a while until it falls to the temperature before excretion. This temperature rise is taken as the timing of excretion.

Further, as shown in FIG. 4, the mounting tool has a multilayer plastic stack (61) structure, and an air chamber (62) is formed between them. The air chamber has a strip shape as shown in FIG.
In the air chamber, the compressed air generated by the compressed air generating means (50) can be filled and extracted by the direction switching means (51) by a signal from the control unit. Two or more air chambers are connected to a plurality of air chambers separated from each other to form a group, and the same group can be filled and extracted at the same time. As an example, the three groups will be described with reference to FIG. 5. For convenience, the three groups will be named (62A), (62B), and (62C). ) Is injected with compressed air to fill (62A). Next, compressed air is injected into (62B), and at the same time, the air of (62A) is removed. When (62B) is full, compressed air is then injected into (62C) and at the same time (62B) is removed.
The shrinkage of the multi-layer plastic of the mounting tool is the smallest in the surface layer, and the portion (62) forming the internal air chamber is soft. As the air chamber is filled with compressed air, the air chamber expands.

If the surface layer (63) of the wearing tool is not contractible, the outer side is pressed even if the air chamber expands, and tries to swell toward the inner side. This acts as an operation of pressing the back layer surface (60) of the wearing tool against the skin. When (62A), (62B), and (62C) complete a cycle, the process returns to the first (62A) and is repeated.
When the air chamber is filled, the wearing device becomes hard and applies pressure to the skin.
Although the mounting tool has been described as a soft plastic as described above, the material of the surface layer (63) can be made of a hard material as proposed in many patents. When a hard material is used, there is some difficulty in wearing feeling, but there is a merit that the excrement can be easily sucked by taking a large gap between the skin and the wearing tool when sucking excrement.
When washing water is applied to the excrement and pressure is applied, the same effect as rubbing with a cloth and wiping can be obtained, and the excrement stuck can be wiped off quickly and reliably.
On the other hand, the air chamber from which the air has been removed becomes soft, and when air is blown away, it becomes a passage from the hot air outlet to the suction port when air is passed between the skin and the wearing tool (2). This serves to blow out excrement and sewage and lead it to the suction port, and prevents the excrement from leaking and wrapping around, and also prevents excrement from being left behind.

Water or air that flows to the fitting is sent from the device through a tube. The tube is flexible and has a composition that does not collapse even when the internal pressure drops below the external pressure. Further, this tube can withstand strong negative pressure during excretion suction without being turned over or walking, and in this patent, such a tube is called a tube.

When air and water are supplied to a tube having the same temperature as the room temperature, water and air having the same temperature as the room temperature are poured into the lower back at the initial stage. Room temperature is below body temperature throughout the seasons, and people feel uncomfortable when they suddenly blow sensitive water on their sensitive skin.
In this device, the warm air and wash water supply lines are provided with return lines that make a pair so that cold air and water do not flow out to the fittings during the preheating period.

Immediately after the excretion detection sensor (67) detects excretion, the warm washing water and warm air are bypassed to the return line before the wearing tool to completely warm the tube. Temperature sensors (18) and (38) are attached to the return line of the tube, and the end of heating is detected when the temperature sensors (18) and (38) rise to a certain temperature. . Another method of the end timing is a method of completing the operation after having been circulated for a certain time by a timer.
After the tube has been heated, the return line is closed, and the discharge of cleaning water from the cleaning nozzle (68) of the fitting and the blowing of warm air from the air supply nozzle (69) are started.

In order to detect the end of cleaning, two sensors for detecting the transparency and conductivity of cleaning water and sewage are attached.
In order to detect the transparency, a corner where external light is blocked is provided in the middle of the suction tube (11), and the light emitting element (86a) and the light receiving element (86b) are placed in a relative positional relationship so that light emitted from the light emitting element can be detected. This is done by measuring how much the light receiving element attenuates.
When water (sewage) mixed with excrement passes between the light emitting element and the light receiving element, a colored color is detected, or light is blocked or attenuated by solid matter.
Contamination can be recognized by changing the light transmittance, coloring degree, and light illuminance.

The conductivity is detected by installing an electrode (87) at a position opposite to the middle of the tube and measuring the resistance value between two points.
Since excrement contains salt taken from food by humans, resistance is generally lower than tap water.

Judgment of cleanliness shows that the transparency and conductivity of sewage show clean values that are higher than the set values, and the values on the supply side before washing the waste and the sewage side after washing the waste are the same It is done by judging whether or not. The comparison between the two is effective when the washing water is cloudy and the transparency is poor, or when the conductivity is high due to salt or the like, the transparency and the conductivity cannot be regarded as the end.
However, it is possible that the conductivity of the cleaning water intentionally made basic or acidic in order to give the cleaning water a salinity or bactericidal effect may be better than the excrement, and the conductivity cannot be compared. Also, in the measurement of conductivity, the correct value cannot be measured unless the two electrodes are completely immersed in water. Although there is no problem on the water supply side, if the excrement and washing water are interrupted on the suction side, the air flows, so that it is erroneously determined that the conductivity is high, that is, it has been cleaned. What is necessary is just to pick up and judge the value with the low electric conductivity which fluctuates in a fixed time, in order to eliminate misjudgment.
The timing for stopping the discharge of the washing water is assured if it is stopped after a certain period of time has elapsed after it is determined that the sewage has become clean.

The configuration of the collection processing means (1) will be described with reference to FIGS. The recovery processing means is roughly divided into three rooms. The first chamber (3) is for excrement collection, the second chamber (4) is for deodorization, and the third chamber (5) is for ventilation. There are openings between the first chamber (3) and the second chamber (4), and between the second chamber (4) and the third chamber (5) so as to form an air passage.
Each room is as follows.

The first chamber (3) is a room for collecting excreta, and a excrement suction tube connected to a wearing tool is connected to this room. An excrement collection tray (70) is placed on the floor of the first chamber (3). Dispose of waste every time the tray is full.
This room has a structure in which negative pressure is generated when a blower means (20) such as a blower described later rotates. It is desirable to attach the tip of the excrement suction tube as low as possible so as not to roll up the excrement during suction.
A chemical solution is injected into the first chamber (3) from the chemical solution injection means (71) for the purpose of deodorization and sterilization.
The timing of injecting the chemical solution starts at the start of excretion aspiration and stops at the end of excretion aspiration.
The chemical solution is preferably a treatment agent mainly composed of chlorine dioxide in terms of sterilization, deodorization, and generation of carcinogenic substances, and is sprayed and injected into the first chamber (3) or in the middle of the suction tube (11). . It is desirable to make the injection volume proportional to the amount of excretion, but the required amount varies depending on the urine with relatively few germs and smells and the stool with many germs and smells, but the amount of excretion is difficult to detect. Bacteria speed and deodorization speed are fast, but it is sufficient that the odorous substance is decomposed and the activity of various bacteria is stopped, and the concentration in a state dissolved in sewage is practically acceptable at 1 to 10 PPM.

The second chamber (4) next to the first chamber (3) is a room for sterilizing and deodorizing the air coming from the first chamber (3). The deodorizing means (72) comprises an activated carbon filter that adsorbs and decomposes odorous substances and a deodorizing agent. Typical examples of human odor are ammonia, hydrogen sulfide, and methyl mercaptan. Odor is completely deodorized by decomposing odorous substances and combining other substances. An acidic deodorant is effective for basic ammonia, and a basic deodorant is effective for acidic hydrogen sulfide. For neutral odorous substances and bacteria, disinfectants / deodorizers that decompose molecules with active oxygen and chlorine and cell membranes are effective.
Since this apparatus is a closed circulation type, there is no dilution effect by outside air. Therefore, the odorous substance in the circulating air has a high concentration and does not decrease. It is necessary to quickly deodorize and prevent odor leakage.
In the present invention, three or more kinds of deodorizing means (72a), (72b), and (72c) each having an effect on odor substances having different properties are separated and attached so as not to come in contact with each other. Yes.

The third chamber (5) following the second chamber (4) is provided with the blowing means (20) and the heating means (21). The suction port of the blowing means is connected to the second chamber (4).

There are four operating modes of the blowing means: a preheating mode, a suction mode, a drying mode, and a stop mode. The preheating mode starts with the detection of excretion and ends with the heating of the tubes (12) and (13). This mode is a mode in which the warm air is returned to the suction side of the air blowing means by the switching means 7 (81) in front of the wearing tool. The heating means (21) is located at the outlet of the blowing means and controls the heating according to the air volume of the blowing means, and also reflects the measured value of the temperature sensor (18).
The preheat mode ends when the tube and device rise to a temperature equal to the body temperature.

The suction mode starts with the end of preheating and ends with the detection that the sucked sewage has been cleaned. In this moat, the path is switched, and a flow path from the blowing means to the mounting tool is formed.
At this time, the ventilation means ventilation amount becomes maximum.

After suction mode, it becomes dry mode.
In general, drying means that moisture has evaporated and humidity has dropped. However, in a closed circulatory system, as the moisture evaporates and the humidity approaches 100%, the amount of evaporation decreases and drying becomes impossible.
Therefore, drying of this apparatus is performed as follows.
Stop discharging the cleaning water as soon as the suction mode ends. After that, if this state continues to blow only with strong wind power in a closed state for a while, the water on the skin and the wearing tool is blown away.
However, it is difficult to blow off the moisture moistening the skin and the surface of the wearing tool. The state where the water that can be blown off is completely blown off is determined by the optical sensor (86) attached to the suction tube (11). it can. In other words, the light intensity detected by the light sensor is considered to have been blown away when the intensity change of light intensity disappears, as the intensity continues to change as the droplets cross the light sensor while the splashed water is scattered. be able to.
The amount of odorous molecules at this point is being reduced by the deodorizing effect of the chemical solution and the deodorizing effect of the second chamber (4).

When the odor amount falls below the permissible value, a part of the circulating air is discharged from the closed circulation system through the opening / closing means (84) to the outside, and instead is replaced by outside air that takes in external air through the opening / closing means (83). enter. That is, part of the high-humidity circulating air is discharged to the outside, and external low-humidity air is taken in.
The discharge position of the high humidity air is preferably after the outlet of the blowing means and before the mounting tool, and the outside air intake position is preferably near the outlet of the mounting tool. When the uptake is far from the outlet of the wearing tool, the pressure of the wearing tool becomes high, and the water blowing at the initial stage of the drying mode is incomplete, and there is a risk that water and excrement left behind will be leaked from the gap of the wearing tool. The end timing of drying is difficult to grasp at the humidity after drying, and it is practical to consider the end of drying after a certain time of drying.

Stop mode is the mode that only detects excretion after drying.
The stop mode is provided with a complete stop for stopping all ventilation and a stop mode for forming a ventilation circuit from the first chamber (3) to the third chamber (5). In the stop to form the ventilation circuit, the amount of ventilation may be fine, and drying, deodorization and sterilization of the first chamber (3) and the second chamber (4) will be complete.

An example of the formation of the suction air ventilation path is shown in FIG. The air supply for excrement suction passes through the tube (12) and the switching means 7 (81) to reach the wearing tool.
In the preheating mode, the flow to the wearing tool is stopped, and the switching means 7 (81) returns to the inlet of the folding air blowing means. The switching means 7 (81) can be switched by a driving force such as electricity or air. Another example of the passage formation is shown in FIG. In this method, the apparatus is provided with a switching means 4 (22), and a switching means 5 (23) is provided on the wearing tool side. In the preheating mode, the switching means 4 (22) is driven by electricity or air and the air exiting the blowing means enters the tube (13) after exiting the switching means 4 in the preheating mode. The air from the tube (13) is more likely to flow to the tube (12) than to flow to the wearing device side by the switching means 5, and the flow returns to the blowing means through the switching means 4. The circuit formation in the dry mode and dry mode is as follows. The air that has exited the outlet of the blowing means exits the switching means 4 and then enters the tube (12). The switching means 5 has a non-return mechanism and cannot flow to the tube (13) but flows to the wearing tool side.

Washing water for washing the wearing tool and excrement is stored in the water storage means (30).
The washing water is pressurized and discharged by the water supply means (31).
The washing water forms different flow paths depending on the mode.
The first flow path is formed for sterilization and preheating in the stop mode. The washing water exits the water supply means (31), passes through the switching means 1 (33), and further undergoes electrolytic sterilization means (34). And return to the water storage means (30).
Heating means (32) is attached to the outlet of the water storage means (30), and energization and circulation are repeated so that the temperature of the water storage means becomes the same as the body temperature.

The second flow path is formed in the preheating mode. The washing water is a route that is recovered by the water storage means through the turn-up tube (16) after leaving the water supply means.
This flow path is formed when excretion is detected and the preheat mode is entered. The timing for stopping the preheating of the washing water is regarded as the end timing when the temperature sensor (38) installed in the return line reaches the set value.

The third channel is formed when the excrement is washed. The washing water is discharged from the washing nozzle (68) of the wearing tool through the switching means 1 (33), the switching means 2 (36), the tube (15) and the switching means 3 (37) after leaving the water supply means. . The excrement is flushed with the washing water and sucked into the excretion suction port.

If the washing nozzle is not completely stopped after washing, water will leak out when pressure is applied to the wearing tool or when the posture changes.
In order to prevent water leakage, there are methods such as narrowing the nozzle, attaching a shut-off valve to the tip, or discharging water and replacing it with air at the end, or backflowing water and sucking air from the nozzle.

The water storage means (35) is a water storage means for storing wash water that can be continuously processed by the apparatus.
What is necessary is just to be more than the same capacity as a collection tray.
Acidic electrolyzed water made separately from this device is used as the washing water. As another method, as shown in FIG. 7.8, water sterilized by electrolytic sterilization means with electrolytic sterilization means (34) in the apparatus can be used.
The use of acidic electrolyzed water as washing water has a sterilizing effect, which is useful for sterilizing and disinfecting the skin of a nurse. In addition, human skin is maintained acidic to maintain resistance to germs. Prevent bacterial infections.

Next, a method for manufacturing the electrolytic sterilization means will be described with reference to FIGS.
If the water storage means (30) is kept at a temperature equal to the body temperature, it is possible to quickly discharge comfortable washing water to the human body after detecting excretion. However, if the heat is kept for a long time, germs will propagate, which is not preferable for a patient who is a sick person. As a preferable sterilization means, there is an electrolytic sterilization means.
The electrolytic sterilization means is a means for partitioning water in which salts are dissolved with a semipermeable membrane and applying electrodes to both ends and applying a DC voltage to electrolyze to produce a negative ion substance at the positive electrode and a positive ion substance at the negative electrode. There are a 2 漕 type electrolyzed water production method and a 3 漕 type electrolyzed water production method shown in Fig. 11 according to the partitioning method with the semipermeable membrane and the salt injection method. When salt is used as the salt, hypochlorous acid is produced at the positive electrode and caustic soda is produced at the negative electrode. Ozone is also generated at the positive electrode.
These sterilize bacteria in the water and suppress the growth. The water is mixed after passing through the electrolytic sterilization means and returned to neutral salt for safety.
If water circulation is too early, the amount of acid and alkali separated will be small and the sterilization effect will be thin. The desirable form is to intermittently circulate and make the amount equal to the volume of the electrolyzer.
It is also possible to attach electrolytic means to the apparatus and use only electrolytic acid water for cleaning. In this case, it is necessary to discharge electrolytic alkaline water from the electrolytic means at an appropriate period.

Detailed operations of the switching means 5 (23) and the switching means 3 (37) will be described with reference to FIG. When there are three ports a, b, and c, when the switching means pays attention to the port a, when fluid flows from a to the switching means, it flows to c and the flow to b is blocked. The When the flow of a is reversed, the fluid flowing in from b flows out to a. For b, the flow stops.
The power source can be realized by electricity, air pressure, water pressure, or the like. However, the switching means does not require a special power source if it needs to be placed close to the wearing tool, and is small when the flow of b and c is blocked by the flow of fluid (air or water) in a. , Become lighter. As an example, a check valve can be attached to b and c so that b flows from a to b and c flows only from c to a.

The switching means 1 (36) and the switching means 4 (22) cross the flow directions. As shown in FIG. 10, when there are four ports a, b, c, d and the switching command is in state 1, the flow from a goes to b, the flow from c goes to d, and in the other state 2 The flow from a goes to c, and the flow from b goes to d.

The direction switching means (51) is a means for sequentially switching the flow entering from one inlet port to one of a plurality of outlet ports, and there is also a method of opening and closing an electromagnetic valve with an electrical signal. As another method, the air pressure applied to the inlet port can be switched.

The present invention proposes an excrement collection processing apparatus to which negative ion generation means (90) is further added in addition to the excrement processing.
The fourth chamber (6) has a structure independent of the flow paths of the first chamber, the second chamber, and the third chamber. There is a negative ion generation means (90) inside, and air is taken in by a blower means (91) such as a fan, and negative ions are charged and discharged. Negative ions are generated by the ion generating means (90) installed in the middle of the air flow path, but since many patents, literatures, etc. have been issued, details are omitted.
By pouring negative ions into the room where the cared person is located, a comfortable space is created and the deodorizing effect of negative ions is exhibited.
Further, by adding humidification means to the air flow path of the fourth chamber (6) and adding humidity, the residence time of negative ions can be extended, and the effect of negative ions can be further enhanced.
