Description

The present invention relates to the cleaning care equipment catheter outlet portion, in particular, it relates to cleaning care equipment very suitable catheter outlet to the cleaning care for outlet infection of the catheter in the peritoneal dialysis.

  Tubes (catheters, cannulas, etc.) and linear bodies are inserted in various places in the living epidermis (neck, arms, torso, abdomen, thighs, etc.), and the body fluid, medicine, etc. inside and outside the living body while maintaining this insertion state properly There is a therapy for treatment and recovery of various diseases by communication, filtration and circulation. For example, artificial dialysis is a typical treatment technology that is generally generalized as blood purification therapy that artificially substitutes for kidney function, and hemodialysis (HD), depending on the patient's medical condition and intention, etc. In addition to peritoneal dialysis (PD), therapies such as hemofiltration (HF) and hemodiafiltration (HDF) are being performed.

  In peritoneal dialysis, after performing surgery for placing a cannula in the abdominal cavity, a dialysate containing high concentration of glucose (osmotic substance) is stored in the abdominal cavity for a predetermined time, while the peritoneal membrane is used as a semipermeable membrane, It is a therapy that purifies blood by transferring waste and waste in the blood, salt, excess water, etc. to the dialysate side and solute exchange on the principle of ultrafiltration by diffusion and osmotic pressure, and visits once or twice a month The basic form is home care that can be completed with a degree.

  As a treatment form, continuous portable peritoneal dialysis (CAPD) performed by a helper or the patient himself according to the life rhythm 3 to 5 times a day according to the life rhythm, and automatically using the bedtime to dialysate exchange There are two main types of automatic perfusion dialysis (APD), and in any case, it takes a long time to perform slow dialysis, so there is less burden on the cardiovascular system and no extracorporeal blood circulation. So blood pressure management is easy. In addition, because the time taken to stay in the hospital is shorter compared to other therapies, and it is basically possible to continue the usual life except for the dialysate exchange work, for example, attending school, working, housework, travel, etc. are also possible. It is. Furthermore, in recent years, technological developments such as a dialysate that can be stored for a longer time, and a safer and easier dialysate replacement method and automation have been advanced. For this reason, peritoneal dialysis therapy is now more and more developed and widespread.

  Here, in a situation where a pipe or the like is inserted through the living body epidermis as described above and fluid is communicated, in addition to an infectious disease such as peritonitis due to contamination of the fluid being communicated, foreign matter is communicated from inside and outside Since bacteria and the like are easily intruded into the body, infections at and near the insertion site always become a problem. In peritoneal dialysis, in particular, a catheter with a cuff forms a subcutaneous tunnel from the outlet of the skin to the inside of the abdominal cavity. If infection care around this outlet is neglected, in addition to the so-called infection of the outlet, Cause bacteria may travel deep inside the tube to cause so-called subcutaneous tunnel infection. In peritoneal dialysis, as described above, the daily management of the outlet and the bag (dialysate) replacement are basically performed by an layman such as a patient, so when care or learning of the outlet or replacement work is not sufficient, Risk of developing a new infection.

  Conventionally, in peritoneal dialysis, peritonitis due to dialysate contamination and outlet infection are regarded as two major complications, and various measures have been taken. As a result, in accordance with various improvements such as bag replacement systems and devices, and the spread of patient education, cases of peritonitis have been successfully reduced in recent years. On the other hand, the incidence frequency of infections other than peritonitis has not changed much as before, especially the exit and subcutaneous tunnel infections are the most frequent cases, and once affected, it takes a long time to recover. Life of dialysis is largely lost, but there are many unsolved parts, which is one of the pressing issues in peritoneal dialysis.

  Careful and careful care of the exit area is essential as a preventive measure for the exit area infection, in order to avoid serious complications as described above. The usual care of the outlet area is performed manually. First, prepare necessary items such as gauze and towels, move to a clean room such as a bathroom, wash your hands thoroughly, and release the tape fixing of the catheter, The subcutaneous cuff portion is manually palpated for catheter observation. Next, after observing the exit area, such as inflammation, rash and pain, and confirming that there is no abnormality, the exit area is cleaned. If a prescribed symptom is found at this stage, a doctor visit is recommended. In washing the outlet, usually gauze or the like is mixed with a disinfectant, and carefully sterilize the outlet with the disinfectant several times, taking care not to pull the catheter. Finally, after carefully wiping the water to ensure drying, a moisturizing ointment or the like is applied and the catheter is taped again at the outlet. In addition, instead of the disinfecting solution, washing with well-foamed soap foam and shower washing with appropriate fluid pressure are also performed.

  In the above-mentioned outlet care, the catheter is firmly fixed with a tape or the like so that it does not move relative to the epidermis in order to prevent irritation due to friction between the catheter and the skin, wound formation, and invasion of bacteria etc. There are two important points that should be done and that good quality skin care should be done to maintain the healthy skin and maximize the inherent infection defense mechanism. It is said.

  On the other hand, with regard to outlet part care, proposals of prior art such as Patent Documents 1 and 2 have also been made. Patent Document 1 proposes a sterile isolation means in peritoneal dialysis or the like, in which an infectious biological site such as a catheter entry incision site is sealed with a predetermined enclosure and a sterile gas is blown into the interior of the enclosure. Specifically, a rectangular dish-like enclosure provided with an opening through a filter is covered toward the incision site in a state in which the catheter is inserted and tightly sealed on the skin, and sterilization such as chlorine or ozone is performed. After the gas has been sent through a filter that can block the passage of bacteria, it is kept for a predetermined time, and then a dry non-reactive gas such as compressed air is sent to expel the sterilizing gas from the surrounding body, It is intended to sterilize the exit site.

  Patent Document 2 is a protective device for protecting a portion where a tube or the like penetrates the skin of a living body from infection, and is a covering portion provided with a sticking portion attached to the skin and an opening which can be covered with a lid. By covering a penetrating portion such as a tube, the tube and the like can be fixed in a sealed state around the penetrating portion, and the lid is provided with an air-permeable filter function. According to this configuration, the tube or the like is prevented from moving to prevent detachment from the living tissue, and the inside space can be filled with or ventilated with a drug to prevent the reproduction of various bacteria and the occurrence of infection.

  On the other hand, with regard to cleaning devices and skin care devices intended for living epidermis, there have also been proposed conventional techniques such as Patent Documents 3 and 4. Patent Document 3 shows several cup-like shield structures for perfusion and scavenging fluid to a wound, and after covering the wound with a hollow spherical shield, the inside of the shield is a suction tube and a vacuum breaking hole. It is a technology that purifies wounds by injecting clean water (sterile saline solution etc.) from a nozzle toward a wound with a predetermined pressure while vacuuming to a predetermined level to clean the wound. Also, the shield is in closed loop communication with the portable unit equipped with a vacuum source via a tube or the like.

  FIGS. 4 and 5 of Patent Document 4 show a cleaning tool for discharging micro-bubble mixed electrolyzed water, and this cleaning tool is a discharge water flow path for discharging electrolyzed water containing micro bubbles and A drainage passage for sucking and discharging the electrolyzed water discharged from the discharge passage, and a seal portion for closely sealing the discharge passage and the drainage passage to the portion to be cleaned; Electrolyzed water containing microbubbles is discharged from the discharge water channel toward the epidermis from the discharge water flow path in a state where the seal portion of the header portion is in close contact with the epidermis of the scalp and face of the carer to wash and disinfect the epidermis. It is described that the electrolyzed water discharged from the water channel is discharged.

  However, in the case of conventional manual outlet part care, as described above, the number of operation steps is complicated, and in particular, the operations of disinfection and drying need to be carefully repeated, and liquid in the abdomen (shower etc. Because the preparation and post-disposal are also very troublesome because it is applied and cleaned, the burden on the workers (nurse etc.) and the patient himself is large, and at least in this respect it is a therapy with extremely poor medical economics. In addition, for example, there is a case that the outlet part care of many hospitalized patients may be performed at the same time, and if it is performed by other than the patient, basically one worker needs to perform for one patient, so work efficiency is It is extremely bad that the shortage of nurses may lead to congestion of patients in need of care.

  In addition, when antiseptic solution or soap is used, it may cause adhesion of wrinkles and sebum on the skin, and run-out, which is a problem. This is because antiseptic solutions etc. have not only a considerable degree of tissue damage to normal skin, but also have bactericidal properties against indigenous bacteria effective for the formation of so-called skin barrier of normal skin, It is considered that when a disinfectant solution or the like is applied to the skin, even the skin barrier function originally possessed by normal skin is greatly impaired, and the growth of pathogenic bacteria is facilitated. For this reason, in recent years, there has been an increasing demand for an outlet part care which can properly maintain the skin barrier function without using a sterilizable film material, a disinfectant and the like.

  On the other hand, the enclosure of Patent Document 1 and the protective device of Patent Document 2 are basically fixing devices for fixing the catheter at the outlet by always wearing them, and also isolating the outlet from the outside. Although the main focus is on maintaining properly, always wearing such a fixing device physically interferes with the movement of the body more or less constantly, and also mentally It must be said that it is bothersome and inconvenient because it must always be aware of the presence of fixed tools such as foreign objects and excessive consideration. In particular, the significance of peritoneal dialysis, which is being researched and developed to reduce the burden of dialysis and expand the range of free time and activity, may be greatly impaired. In addition, since there is a site that is in close contact with the skin for a long time, this site is likely to cause a skin disease, which may cause an exit site infection.

  In addition, since cleaning and sterilization of the outlet are all using sterilizing gas and chemicals, there is a possibility that even if sterilization can be performed, the skin barrier function of the outlet may be impaired, and as a cleaning care device Usability and cost become worse. Furthermore, since all the covering structures are complicated structures such as filters, lids and split pieces, the productivity as a product can not be said to be good, and there are a large number of processes such as assembly / attachment and disinfection. It can not but become. Therefore, neither can be said that medical economics are favorable.

  On the other hand, Patent Documents 3, 4 or this kind of technology is only a technology for cleaning the epidermis and wounds, and therefore, it is indispensable to care and clean around the catheter outlet as described above. Information on various structures and devices is not disclosed at all. Therefore, it can not be used at all as care and cleaning technology for the outlet. In addition, since the vacuum source and the electrolyzed water generator are complicated and expensive, the productivity is low and the use scene is limited.

Therefore, the present invention was developed as a result of intensive research conducted by the applicant in order to solve the above problems, and its object is to ensure the proper function of the skin without using a disinfectant or the like.

  The fixing portion 20 is also provided at an appropriate position of the case 1. As shown in FIGS. 1 and 3, the fixing portion 20 of this example is formed near the axial center position of the outer peripheral surface 11 and near the top position of the hemispherical surface portion 11a, and the container 1 is set to the patient At this time, it is a position located just above and facing the outlet 5 of the catheter 6. At this time, the insertion portion 7 holds the catheter 6 inserted and removed from the outlet portion 5 in a slightly inclined state with respect to the epidermis due to the relationship with the position of the insertion portion 7 described above, and the spout fixed to the fixing portion 20 The nozzle unit 3 (jet nozzle 8) faces the outlet portion 5 substantially in the vertical direction, so that the jet nozzle unit 3 may be directly exposed to the vicinity of the outlet portion 5 where cleaning care is required. It becomes possible.

  In addition, the fixing portion 20 can fix the jet nozzle unit 3 to the container 1 in a sealing manner. As shown in FIGS. 4 and 5, in the sealing and fixing structure of this embodiment, a step (not shown) provided on the inner peripheral surface of the fixed portion 20 and a step 3a provided on the outer peripheral surface of the jet nozzle unit 3 In close contact with each other, the inner peripheral surface of the fixing portion 20 and the outer peripheral surface of the jet nozzle unit 3 are fitted in a shape-matching manner, so that it is extremely easily removable while having a sufficient sealing property. The container 1 and the jet nozzle unit 3 can be appropriately selected as long as they have a sealing structure that can be easily attached and detached. For example, a structure in which screw portions are screwed with each other or an O-ring may be used.

  In this example, the outflow portion 4, the insertion portion 7 and the fixing portion 20 are integrally formed on the container 1 with a transparent or semi-transparent resin. Materials and methods for integral molding can be applied various techniques depending on the implementation, but it is premised that they are materials with appropriate safety as medical instruments to be used by directly applying to human skin. In particular, in the case of making the container 1 disposable, it is preferable to have a point which can be mass-produced inexpensively.

  Furthermore, although not shown, the jet nozzle unit 3 may also be integrally molded with the container 1. That is, the shape and structure corresponding to the jet nozzle unit 3 may be integrally formed in the space 1 inside the fixed portion 20 in the container 1. In this case, for example, if the fixing portion 20 is formed in a bottomed shape, and the blowout nozzle having an appropriate structure is integrally molded to the container 1 at the bottom, the blowout nozzle unit 3 can be substituted.

  Furthermore, although not shown, in order to reduce the inner volume of the container 1, a suitable area including the opening 2 may be a bellows structure. In this case, for example, in this example, a bellows structure including a plurality of steps formed by rotating the outer peripheral surface 11 of the container 1 along the opening 2 at appropriate intervals is formed, and the container 1 is contracted by contracting the bellows structure. Becomes possible to reduce the volume. The bellows structure of the container 1 is preferably formed thin by blow molding made of polyethylene or the like to have flexibility and lightness. Such a bellows structure makes it possible to compactly accommodate a large number of containers 1 which are difficult to be accommodated in a distorted shape, even when not in use.

  As shown in FIGS. 1, 3 and 5, the opening 2 encloses the care area W (FIG. 2) around the outlet 5 in the opening 2, and the container 1 is held in contact with at least the airtight state. An annular seal 10 is provided. The seal structure of the annular seal portion 10 is not particularly limited as long as it can properly contact the skin and seal the liquid inside the container 1 according to the use conditions of the cleaning care device.

  The annular seal portion 10 in this example is formed of a gel-like elastomer resin. The gel-like elastomer of this example is a low resilience (appropriate hardness or repulsive force), that is, a gel-like gel which is elastically deformed by pressing and hardly returns from the deformation and does not adversely affect the human epidermis. Various materials can be applied as long as the resin material is transparent. Further, the higher the frictional property with respect to the human epidermis, the more easily it is closely fixed to the epidermis, which is preferable. Examples of the material include, in addition to soft urethanes, materials comprising gel-like silicon, gel-like poval, gel-like polyester, gel-like polyethylene, gel-like polyamide, gel-like acrylamide and the like. If the annular seal portion 10 is formed in this manner, it is preferable because it closely adheres to the fine irregularities of the human skin well and so on with high sealability. The annular seal portion 10 may be provided with a bonding means such as double-sided tape to improve the adhesion and fixing property.

  As shown in FIGS. 1, 3 and 5, on the outer peripheral surface 11 of the case 1, the attachment portion 12a for attaching a band for winding the case 1 around the body and fixing the case 1 and the case 1 directly downward from the neck of the body The attachment part 12b which attaches the string-like body (not shown) which can be suspended and held is provided. In the setting process of the container 1 described later, the mounting portion 12a is the mounting portion of the band, and the mounting portion 12b is the mounting portion of the string-like body. The band is provided on the hemispherical surface portion 11 a which is located on the side of the case 1 when it is set on the patient, in order to wind it around the human body in the horizontal direction. On the other hand, the string-like body is provided on the top of the semi-tapered surface portion 11 b which is the longitudinal side of the container 1 so as to hang around the neck when the container 1 is set in the patient. However, the position and structure of the mounting portion and the means for fixing to the body can be arbitrarily selected according to the implementation.

  Next, in FIG. 2, an example of the cleaning care apparatus of the exit part 5 of the catheter 6 of this example is demonstrated. The figure is a circuit diagram showing an example of the cleaning care device of this example. The water supply and drainage unit 13 incorporates a water supply tank 14 and a water supply pump 15 for supplying water to the bubble generator 3, a drainage tank 17 which is drained from the outflow part 4 via a drainage pipe 16, and a controller 21 for control. ing. In addition to the above, a heater (a heater capable of heating the water supply tank 14 or the water supply pipe 18), a blower (not shown), or the like can be appropriately incorporated as well, for warming the water supply. Tap water, predetermined washing water and the like are stored in advance or appropriately replenished in the water supply tank 14 provided to a predetermined capacity.

  The feed water pump 15 can be arbitrarily selected according to the implementation without particular limitation, but for example, a spiral centrifugal pump including an impeller, a motor, and a casing (not shown) can be used. In this case, the central portion of the impeller is attached to a pump drive motor, and the motor is rotationally driven to suck in liquid from the water supply port of the pump from the water supply tank 14 via piping and discharge it from the discharge port to the water supply pipe 18 side. Ru.

  The control controller 21 can apply any technology without particular limitation as long as various controls can be controlled. For example, an operation unit including buttons corresponding to various control functions, and this operation An input processing circuit that is electrically connected to the control unit and converts signals from the operation unit and various sensors / switches, an output processing circuit that outputs a signal according to the calculation result, or a control program, The control unit is composed of an operation processing unit and a storage unit (CPU, ROM, RAM, timer, etc.) that executes various arithmetic processing based on the above. , Etc., each sensor (temperature sensor, pressure sensor, flow sensor, etc.), or a power switch, etc., to facilitate various operation control To be able to may be configured.

  As described above, various types of operation control can be performed by configuring the control controller 21 and various sensor switches. As the operation control of the water supply and drainage unit 13, in addition to the basic control in which the temperature and time of the water supply are set in advance according to the condition of the affected area and the like for cleaning care, for example, timer control of the water supply pump 15 etc. Control to intermittently supply water and provide intermittent cleaning care, or switch the supply circuit to a fan (not shown) after cleaning care and supply warm air from the nozzle of the jet nozzle unit 3 to dry warm air It is possible to perform control to be applied, etc. Further, it is possible to configure temperature setting of water supply or air flow or adjustment of flow rate, water supply pressure or the like by the operation panel section. Furthermore, if the gas mixing device is properly incorporated in the water supply side circuit, it is also possible to spray a sterile gas (inert gas) to the affected area after the cleaning care is completed.

  In addition, in order to facilitate lightweight, compact and stable transportation of the water supply / drainage unit 13, the positional relationship in which the elements to be incorporated are accommodated is appropriately combined, and optimally arranged so as to be stable when placed on the floor. Is recommended.

  In FIG. 2, an ultraviolet irradiation unit 19 for sterilization is provided around a water supply pipe 18 for supplying water to the bubble generator 22. The configuration of the ultraviolet irradiation unit 19 can be optionally selected according to the implementation, but for example, a transparent member is used for a part of the water supply pipe 18 provided with the ultraviolet irradiation unit 19 and UV light is emitted around this transparent tube A diode (LED) module can be provided. At this time, by arranging the LEDs in an appropriate array, etc., an efficient dose distribution and wavelength range (200 nm to 320 nm etc.) can be obtained inside the water supply pipe 18, and the bactericidal action is enhanced. It is suitable. In addition, it is preferable that the LED module be electrically connected to the control controller and configured to be controllable.

  In the bubble generator 22 (or the orifice 9), ozone water may be used to generate microbubbles / nanobubbles. In this case, for example, an ozone generator (not shown) may be incorporated in the water supply / drainage unit 13, and ozone may be mixed with the liquid supplied from the water supply tank 14 by the ozone generator on the water supply pipe 16 side. In this case, the configuration of the ozone generator can be arbitrarily selected according to the implementation, but for example, the discharge element circuit and the electrode plate electrically connected to the control controller 21 have the external air taken in from the intake pipe The electrode plate discharges (surface discharge, silent discharge, etc.) to generate ozone, and this ozone is supplied to a predetermined ozone mixer via a supply pipe, and ozone is mixed in the water supply in this ozone mixer. Configured to be.

  In addition, as shown in FIG. 2, in order to facilitate the operation control of the cleaning care device and widen the range of variations, and to improve the workability such as assembly and disassembly of the device, At appropriate locations, one or more suitably configured valves or couplers (16a, 18a) may be provided. Further, the heater (not shown) may be a ceramic heater which can be heated so as to be wound around the outer periphery of the water supply pipe 18 at an appropriate position of the water supply pipe 18.

  FIG. 7 is an external perspective view showing another example of the case 1 of the present example. Further, in FIG. 10, in the case 1 of the other example shown in FIG. 7, instead of the opening 2, a bowl-shaped opening 2 'is formed, and an annular seal 10' is provided in the opening 2 '. The figure shows a partially enlarged cross-sectional view in which the annular seal portion 10 'is enlarged. In the example of the figure, the same reference numerals are given to the same parts in the case 1 and the description will be omitted.

  As shown in FIGS. 7 and 8, the container 1 of this other example also includes an opening 2, an outlet 4 for draining drainage and the like in the container 1 out of the container 1, and an outlet 5 of the care area W. It has the insertion part 7 for inserting the taken-out catheter 6 out of the container 1, and at least these are integrally formed by the container 1 and resin. Further, a band attachment portion 12 a is provided on the outer peripheral side surface of the container 1, and a string attachment portion 12 b is provided on the tip end side. In the fixed portion 20 of the container 1 of the other example of the figure, the jet nozzle unit 40 of another example (FIGS. 6 and 9) to be described later is detachable from the outside of the container 1. A flat portion 20a is provided on the inside 20, and the insertion portion 7 is opened as a hole at the center position of the flat portion 20a, and the jet nozzle unit 40 of another example is formed on the inner peripheral bottom portion of the fixed portion 20. An L-shaped engaging groove 48 engageable with the projecting portion 47 and an elongated hole 49 capable of inserting and holding the injection nozzle 43 are provided.

  In the other example of the case 1 of FIG. 7, the whole is slightly thinner than in the case of the example of FIGS. 1 and 3, and the opening 2 is not provided with an annular seal portion. The configuration is simpler than in the present example.

  On the other hand, FIG. 10 shows an example in the case where an annular seal portion 10 ′ is provided at the opening 2 ′ in another example in which the opening 2 ′ is formed instead of the opening 2 shown in FIG. It is sectional drawing to which this cyclic | annular seal | sticker part 10 'was expanded. In this example, the end of the opening 2 'protrudes outward in a bowl-like shape to secure the contact area with the skin, and the annular seal 10' is provided on the extended portion.

  Subsequently, the action of the cleansing care device at the outlet 5 of the catheter 6 of the present example will be described together with a care cleansing method using the same. The container 1 is connected to the water supply / drainage unit 13 shown in FIG.

  In the container setting step, the catheter 6 taken out of the outlet 5 is inserted out of the container 1 through the insertion part 7, and the container 1 is kept in an airtight state with the annular seal part 10 surrounding the care area W. It is made to hold close.

  Specifically, first, the end portion of the catheter 6 inserted from the outlet portion 5 of the patient is grasped and inserted into the insertion portion 7 of the container 1, and the container 1 appropriately surrounds and covers the care area W In the state, the annular seal portion 10 is brought into close contact with the skin appropriately. Under the present circumstances, when sliding between the catheter 6 which is a skin fixed side, and the penetration part 7 of the container 1 which is a movable side, it should be noted about the damage of the exit part 5 vicinity. That is, the catheter 6 should not be pulled excessively, and the catheter 6 in a state of being inserted into and held in the insertion portion 7 will not be in a state where the vicinity of the outlet portion 5 is excessively stretched. Should. Conversely, the length of the catheter 6 should not be excessively left inside the body 1. Further, although not shown, when using the cleaning care device (cleaning care method) of the present invention with a cap or the like, it is necessary to appropriately seal the extraction side end of the catheter 6 in a liquid tight manner. . Of course, it is recommended that the site 1 before use, the room where the body 1 is used, the external environment, or the region such as the care area W be appropriately cleaned and cleaned in advance.

  Further, in the case of the container 1 of this example, if the crest portion of the semi-tapered surface portion 11b is directed upward (set the hemispherical surface portion 11a directly below) in the care area W, the outflow portion 4 is directly below. It is preferable because the drainage property is improved. After the annular seal portion 10 is properly brought into close contact with the epidermis, the container 1 is appropriately fixed to the patient's body by a band or a string (not shown) provided at the attachment portion. Do. Under the present circumstances, when the band provided in the attaching part 12a is wound and fixed around a body, since the container 1 is reliably stopped and fixed with respect to a body outer_skin | epidermis although it is a simple means, it is suitable.

  Subsequently, in the cleaning care process, the care area W is provided with cleaning care by spouting micro bubbles and nano bubbles. Specifically, it is also possible to control the operation of the cleaning care device according to predetermined care cleaning control (time, temperature, injection mode, water supply amount, etc.) by the operation and control of the controller 21 for control. Basically, predetermined cleaning water containing microbubbles and nanobubbles flows into the interior of the container 1 from the nozzle of the jet nozzle unit 3 of the container 1 by the activation of the device after the container setting step, and this cleaning water is annular seal The care area W is appropriately cleaned and cared while the space between the epidermis having the care area W and the inner peripheral surface of the container 1 is appropriately filled through the part 10.

  The microbubbles are fine bubbles having a bubble diameter of several tens of micrometers or less, and the nanobubbles are ultrafine bubbles having a bubble diameter of several hundreds of nanometers or less. In addition, a microbubble between the microbubble and the nanobubble, that is, a microbubble having a bubble diameter of about several hundred nanometers to ten micrometers is called a micronanobubble. When the cell size is smaller than the micro size, it is known that it has unique properties that are different from those of large size cells that are usually visible to the naked eye, and this point causes some very beneficial effects .

  For example, the floating speed is extremely slow compared to a bubble of normal size. Since the bubble volume is extremely fine, the rising speed becomes extremely small and remains in the liquid for a very long time. As an example, it is known that the floating speed of the microbubbles is about several millimeters to several centimeters per minute, and the nanobubbles remain for several months without disappearing in the liquid. Also, micro bubbles and nano bubbles are negatively charged from the side as colloidal particles.

For this reason, while adsorb | sucking with the fine particle (pollution substance etc.) which carried positive charge, and the very effective washing | cleaning effect of a liquid is acquired, since the bubbles charged negatively are mutually repelled, bubbles merge. As a result, it is difficult to reduce and eliminate fine bubbles due to aggregation and expansion, and the concentration of the bubbles is maintained to obtain a long-term cleaning effect. Furthermore, since it is extremely fine, extremely high pressure is applied to the bubble surface, and in the case of self-crushing after contraction, local high temperature and high pressure is generated while generating ultrasonic waves. For this reason, foreign particles are effectively pulverized, and in particular, organic substances are appropriately decomposed, so that a very high water purification effect can be obtained. In particular, in the case of a nano-sized bubble, it is also known that it is easy to permeate the cell surface and penetrate the cell interior while maintaining oxygen inside. In addition, radical with a high bactericidal action - is also known occurrence effect of ^(OH).

  Due to the above properties, in addition to water purification effects and microorganisms (bacteria and viruses) inactivity and bactericidal effects, physiologically active effects, cytoprotective effects, and growth promoting effects are also known and applied in various forms in a wide range of fields. It is done. Due to such an effective effect, in the cleaning care process, the care area W is sufficiently exposed and immersed in the microbubbles or nanobubbles inside the container 1 to obtain a high cleaning effect of the affected area.

  Various methods such as an ejector method, a pressure dissolution / dissolution method, a swirl flow method, etc. are known as micro bubble to nano bubble generation methods, and any method can be selected in the cleaning care device (bubble generator 22) of the present invention. However, in this example, a so-called venturi method or cavitation method is introduced which can be efficiently produced in large quantities via a squeezed portion (venturi tube, orifice, etc.) having a simple structure. That is, the throttling portion for generating the bubble is provided in the jet nozzle unit 3 itself, and as shown in FIG. 4, it is made to be generated by the orifice 9 provided in the jet nozzle 8.

  In FIG. 4, an orifice 9 which is a throttling portion of the present embodiment is composed of a tapered diameter-reduced portion 9a and a throat portion 9b connected to the diameter-reduced portion 9a and having a narrowed flow path diameter. A gas inflow path 90 communicating the inner circumferential surface portion 9 b with the outer circumferential surface portion of the jet nozzle 8 is provided.

  The jet nozzle unit 3 compresses the gas in the container 1 as a bubble jetted from the jet nozzle 8 into a liquid supplied with water, and the inside of the container 1 is in a negative pressure state with respect to the outside air.

  Specifically, in this example, the liquid supplied from the water supply tank 14 through the water supply pipe 18 reaches the orifice 9 through the flow path portion 32 by pressurization by the water supply pump 15, and from the reduced diameter portion 9a When flowing into the throat portion 9b, the flow velocity increases because the flow passage cross-sectional area is narrowed. Due to the increase in the flow velocity, the static pressure of the liquid is once reduced, and when the fluid passes through the throat 9 b and is jetted out of the injection nozzle 8, the static pressure increases again. At this time, since a negative pressure region relatively negative pressure is formed in the orifice 9 from the outside of the jet nozzle 8, the gas inlet passage 90 opened to the inner peripheral surface side of the orifice 9 is formed. Gas flows into the jet nozzle 8 inside. The gas that has flowed in this way is mixed with the liquid in the flow path as a minute bubble while being compressed. Dissolution in the liquid is promoted by the static pressure difference with the throat portion 9b, and the gas that has become air bubbles is further refined. In this manner, the orifice 9 can be a generator of microbubbles or nanobubbles.

  In addition, since the gas inside the container 1 is taken in continuously while being compressed toward the inward of the jet nozzle 8 through the gas inflow path 90 and consumed in the fine bubbles, in the internal space of the container 1 As a result, the number of gas molecules is reduced relative to the ambient air of the same volume and temperature. Therefore, the space inside the container 1 can be in a negative pressure state slightly lower than the static pressure (external pressure) outside the container 1. The suction effect of the negative pressure to the interior space of the container 1 makes it difficult for the fluid to flow out from the inside to the outside of the container 1, and in particular, the adhesion between the annular seal portion 10 and the skin can be enhanced.

  Furthermore, although not shown, it is preferable to provide an appropriate non-return structure in the system from which the washing water in the container 1 is drained in order to properly form and maintain the above negative pressure state in the container 1. It is. Specifically, in FIGS. 1 and 2, for example, a simple non-return flap gate is provided at the end of the male screw 4a of the outflow portion 4 to allow backflow of drainage into the container 1 when communicating with the drainage pipe 16. Alternatively, a check valve or a simple trap structure may be provided in the middle of the drain pipe 16. Such a non-return structure prevents the suction of fluid into the container 1 through the outflow portion 4, and the negative pressure state in the container 1 is well maintained without being broken.

  In addition to the above, as the structure of the orifice 9, for example, the diameter reducing portion 9a is not formed into a tapered shape and is formed so as to be smoothly connected with the throttling shape of the throat portion 9b. Gas in the container 1 is compressed and taken into bubbles, and the air pressure in the container 1 is the outside air pressure, for example, a structure in which a cavitation generation chamber is formed and an opening on the jet side of the jet nozzle 8 is combined with a diameter expansion structure. Various throttle structure (Venturi structure, cavitation generation structure, etc.) which can be lowered relative to the above can be arbitrarily selected depending on the implementation. Further, such a throttling portion structure may be configured in multiple stages in plural places in addition to a single one.

  Here, a quick and simple cleaning care operation is that the case is in close contact with the patient's epidermis and the annular seal is properly sealed properly, and fluid in the case does not leak out during cleaning of the care area. In the cleaning care device according to the present invention, as described above, the inside of the container 1 is in a negative pressure state by bubble injection from the injection nozzle 8 and the annular seal portion 10 easily adheres well to the skin. Adhesive material such as double-sided tape is formed on the annular seal portion 10 to improve adhesion and fixation, and the case 1 is appropriately fixed to the body by a band or a string-like body attached to the attachment portion. I am able to maintain it. These synergetic effects ensure that the sealability with the surface of the container 1 is kept very good. For example, even if a slight external force acts on the container 1 due to the injection reaction force from the injection nozzle 8 or the swing of the water supply pipe 18 during cleaning care, the adhesion between the annular seal portion 10 and the skin is assured There is no risk of fluid leakage from the container in normal use.

  6 and 9 are external perspective views showing the structure of another example 40 of the jet nozzle unit 3. FIG. 9 is an axial center direction of the annular body 42 of the jet nozzle unit 40 and the jet nozzle 43 in FIG. It is sectional drawing by the AA line cross section which passes through one axial center direction of.

  6 and 9, the jet nozzle unit 40 is formed of a hollow cylindrical annular body 42 having an annular space 41 having a rectangular cross section, and the annular body 42 communicates with the inflow passage 45 in the inside. A space 41 is formed. Since the inflow path 45 is connected so as to be linearly connected in the tangential direction of the circulation of the annular space 41, the cleaning liquid flowing into the annular space 41 can form a swirling flow. Further, the bottom surface side of the annular body 42 is a bottom surface portion 42a which comes in close contact with the flat surface portion 20a of the fixed portion 20 when attached to the container 1 of the other example described above. There is provided an injection nozzle 43 having a flow passage 43 b communicating with the annular space 41. The three injection nozzles 43 of this other example are provided at equal positions with respect to the annular space 41, and are each integrally extended with the annular body 42, and when the ejection nozzle unit 40 is attached to the container 1, the drooping shape is provided. To the care area W.

  FIG.6 (b) is the enlarged view which expanded the P section shown to the figure (a), and was front-viewed. As shown in FIG. 9 and FIG. 9, a gas inflow path 43a is formed in the jet nozzle 43, and a predetermined orifice structure is secured inside as in the jet nozzle 8 (orifice 9) described above. With the injection, micro bubbles and nano bubbles can be generated.

  In FIGS. 6 and 9, the inner peripheral side of the annular body 42 is an inner peripheral surface portion 44 which can be fitted and held tightly with the outer peripheral surface of the catheter so that the catheter can be inserted and held when the container 1 is used. At the upper end, an edge 46 is provided integrally with or separately from the annular body 42 in order to enhance the catheter's holding performance and the cleaning performance of the cleaning liquid. A seal member or the like may be separately provided on the inner circumferential surface 44 to seal between the inner circumferential surface 44 and the catheter. On the other hand, the outer peripheral side of the annular body 42 is the outer peripheral surface portion 42b which is fitted and in contact with the inner peripheral surface of the fixed portion 20. Therefore, in the engaging groove 48 equally provided in the fixed portion 20. Correspondingly, there are provided equally three protruding portions 47 which can be engaged.

  FIG. 8 is an external perspective view showing a state in which the jet nozzle unit 40 of the other example is attached to the fixing portion 20 of the case 1 of the other example. At the time of attachment, first, the three injection nozzles 43 of the ejection nozzle unit 40 are inserted from the upper side of the fixed part 20 into the three elongated holes 49 provided correspondingly to the bottom part 42a. The flat portion 20a is abutted. In this state, the positions of the protruding portion 47 and the vertical groove of the engagement groove 48 are in alignment and engaged, and the outer peripheral surface portion 42 b is closely fitted to the inner peripheral surface portion of the fixed portion 20. Then, when the annular body 42 is slightly rotated, the projection 47 engages with the lateral groove of the engagement groove 48 to stop the movement of the projection 47 in the longitudinal direction, whereby the jet nozzle unit 40 is moved. It is fixed to the fixing portion 20 in a retaining manner.

  11 and 12 show still another example of the jet nozzle unit 50, and FIG. 11 is an external perspective view of the jet nozzle unit 50, and FIG. 12 is an annular body 52 of the jet nozzle unit 50 in FIG. It is a cross-sectional view taken along the line B-B passing through the axial direction of and the axial direction of one of the injection nozzles 53.

  11 and 12, the jet nozzle unit 50 is formed of a hollow cylindrical annular body 52 formed longitudinally longer than the above-described annular body 42, and the annular body 52 communicates with the inflow passage 55 inside. An annular space 51 having a rectangular shape in cross section is formed, which has a larger capacity than the annular space 41 described above. The inner peripheral side of the annular body 52 is an inner peripheral surface 54 which can be inserted through and held at the time of use of the container by tightly fitting with the outer peripheral surface of the catheter, and is secured longer than the inner peripheral surface 44 mentioned above. . At the upper end portion of the inner circumferential surface portion 54, an edge portion 56 is provided integrally or separately with the annular body 52 in order to improve the holding performance of the catheter and the sealing performance of the cleaning liquid. A seal member or the like may be separately provided on the inner circumferential surface 44 to seal between the inner circumferential surface 44 and the catheter.

  On the other hand, as shown in FIG. 12, on the outer peripheral side of the annular body 52, a cylindrical outer peripheral surface 52b is formed on the upper side, and it is connected to the outer peripheral surface 52b on the lower side and contracted toward the bottom side. A tapered surface portion 52c is formed.

  Although the case to which the jet nozzle unit 50 of another example shown in FIGS. 11 and 12 is attached is not shown, it may have the same structure as the case 1 except for the structure of the fixing part. The fixing portion may have any structure as long as it can be fixedly held by closely fitting with the outer peripheral surface portion of the jet nozzle unit 50, for example, a concave tapered shape adapted to the shape of the tapered surface portion 52c and capable of fitting and fixing it. It is sufficient to have a simple hole structure that has a portion and a cylindrical inner peripheral surface portion that can be fitted and held in conformity with the shape of the outer peripheral surface portion 52b, and allows communication between the inside and the outside of the container. In this case, since it does not have a part like the above-mentioned flat part 20a, when attaching to such a fixing part, the tapered surface part 52c of the jet nozzle unit 50 and the concave taper from above the fixing part It becomes possible to attach it only by closely fitting the ring-shaped portion. Therefore, the ejection nozzle unit 50 can be detached from the case with a very simple operation of inserting and removing the fixing portion of such a structure. An appropriate retaining means may be provided to strengthen the attachment.

  Further, as shown in FIGS. 11 and 12, similarly to the inflow passage 45 described above, the inflow passage 55 is also connected so as to be linearly connected in the tangential direction of the circulation of the annular space 51. The inflowing cleaning fluid can form a swirling flow. Further, on the bottom surface portion 52a of the annular body 52, an injection nozzle 53 having a flow path 53b communicating with the annular space 51 is provided. Three injection nozzles 53 of this another example are also provided at equal positions with respect to the annular space 51, and are respectively integrally extended with the annular body 52, and when the ejection nozzle unit 50 is attached to the fixing portion of the container It is formed to head toward the care area W in a hanging manner. In the same manner as the above-described jet nozzle 43, the jet nozzle 53 also has a predetermined orifice structure inside with the gas inflow path 53a, and can generate microbubbles and nanobubbles as the cleaning liquid is jetted.

  The operation of the jet nozzle unit 40 (another example) and the jet nozzle unit 50 (another example) will be described. The washing water flowing into the annular spaces 41, 51 from the inflow passages 45, 55 enters the annular spaces 41, 51. It is a flow that descends to the bottom surface while rotating in a spiral shape, and is pressed into the injection nozzles 43 and 53 at the bottom surface. The jet nozzles 43 and 53 jet the fluid mixed with bubbles toward the bottom side of the annular body 42 and 52 while generating micro bubbles and nano bubbles. More specifically, the fluid flowing into the jet nozzles 43, 53 from the bottom side of the annular space 41, 51 is rapidly opened after passing through the flow channels 43b, 53b having a narrowed diameter. Cavitation occurs, and the cavitation draws external air from the gas inflow channels 43a and 53a to generate bubbles, and fine bubbles are deposited from the dissolved air and vapor, resulting in a long duration and Highly oxidative microbubbles and nanobubbles can be generated in a large amount in a liquid. In addition, fine bubbles generated by cavitation can be easily adjusted by adjusting the flow rate and flow rate of the liquid.

  Further, the case 1 (another example), the ejection nozzle unit 40 (other example), and the ejection nozzle unit 50 (another example) shown in FIGS. Because it has such advantages, it is more preferable in the practice of the present invention. That is, in the other example (FIGS. 6 to 12), unlike the present example (FIGS. 1 to 4), the insertion part for inserting the catheter from the container is provided in the fixing part, and accordingly The catheter injection portion (inner peripheral surface portion 44, 54) is also provided in the bubble ejection unit. For this reason, it is not necessary to separately provide an insertion part in the container, and the structure can be simplified and downsized, and the communication part with the outside air is reduced, so the sealing performance inside the container with respect to the skin can be improved. Specifically, as in the above-described structure, the jet nozzle unit is formed of an annular body that can be fitted to the annular fixing portion, and the structure of the insertion portion is secured inside the annular body so as to surround the catheter. The insertion portion is configured to be able to exhibit a compact and reliable sealing property (adhesion). In addition, since the catheter is held at the axial position of the annular body, the injection nozzles arranged symmetrically around the catheter are uniformly directed from the outlet to the outlet while the catheter is held substantially vertically to the outlet. And it is possible to carry out centralized injection of washing water directly. Moreover, compared to the jet nozzle unit 3, the volume of flushable wash water is large.

  In the outflow step, drainage and the like in the container 1 are made to flow out of the container 1 through the outflow part 4.

  Specifically, after the cleaning care of the care area W has been completed by supplying a predetermined amount of water for a predetermined time, drainage after use and the like remaining inside the container 1 is carried out through a drainage pipe 16 connected to the outflow portion 4 It is made to flow out to the drainage tank 17 built in 13. As control of the outflow process, for example, after the elapse of the care cleaning time set in the timer provided in advance in the control controller 21, a valve (not shown) provided in the drainage pipe 16 is opened to automatically drain the drainage tank 17 or the like. May be drained out, and although not shown, a disposable drainage bag which can be easily removed and attached to the draining portion 4 via a connection portion such as an attachment as a drainage draining destination is placed in the container 1 It may be attached and removed and discarded after care cleaning.

  Furthermore, air or an inert gas may be blown to the care area W after or in the outflow step. In this case, for example, the circuit is switched so as to connect the water supply pipe 18 to a fan (not shown) incorporated in the water supply / drainage unit 13 so as to discharge warm air or inert gas from the jet nozzle 8 Good.

  Furthermore, the cleaning care device of the present invention can be made Internet of Things (IOT) by an appropriate configuration. For example, a predetermined device (a device having a sensor / communication module and capable of acquiring predetermined data from a mounted object) is incorporated in the water supply / drainage unit 13 to automatically control a predetermined device in the unit If connectable and the data from this device can be communicated to a predetermined network via mobile or wired etc., big data analysis in the cloud, for example, care cleaning device according to the patient's personality and symptoms It is also possible to obtain results unique to IOT, such as optimum driving patterns and optimization of care cleaning efficiency in a hospital.

  As an example of the embodiment of the present invention, the case 1 of the present example is formed such that the outer diameter of the hemispherical surface portion 11a is about 100100 mm and the thickness is 2 mm. The diameter is set to about Φ 0.4 mm, and the volumes of the water supply tank 14 and the drainage tank 17 are set to 1500 ml, while the water supplied from the water supply tank 14 is heated to about 30 degrees by the heater and the care cleaning time per one time Is about 2 minutes, the amount of water supplied is about 200 ml, and an example is given in which washing is performed 2-3 times per person per day.

  As dimension formation of the other example of the container 1 shown in FIG. 7, the full width (the distance between the outer end of the attaching part 12a on both sides) is 109.60 mm, the entire length (the distance from the tip of the attaching part 12b to the tip of the male screw 4a) The radius of the hemispherical surface portion 11a is about 50 mm. On the other hand, as the dimensional formation of the jet nozzle unit 40 of the other example shown in FIGS. 6 and 9, the outer diameter of the annular body 42 is 、 28 mm, the inner diameter of the inner circumferential surface 44 is Φ 10 mm, the upper and lower thickness is 9.8 mm, the edge The height from the top of the portion 46 to the bottom portion 42a was 13.9 mm, the inner diameter of the inflow path 45 was Φ3 mm, and the outer diameter was Φ6 mm.
