Description

Technical Field

[0001] The invention relates to the technical field of medical care equipment, in particular to a feces collection device for preventing incontinence dermatitis. Background Art

[0002] There are many treatment options for fecal incontinence, which mainly use adhesive to fix the perianal area, and then use negative pressure adsorption on the stool to absorb the stool. This solution can achieve the purpose of collecting stool, but there are still the following technical problems:

[0003] Since the viscosity of viscose mainly comes from the interaction between molecules. When the viscose molecules fully wet the surface of the adhered object and are in good contact with it, the two form an interaction between molecules, in which water plays a great role in the infiltration of the "glue molecules". However, for patients with fecal incontinence, the continuous outflow of fecal fluid for a long time will inevitably cause high humidity in the anal area, and its sticky environment will be destroyed, thereby reducing its bonding ability and making it easy to fall off, affecting its use. Due to the presence of perianal wrinkles, fecal fluid can easily penetrate slowly from the gaps, thereby causing perianal skin lesions and causing environmental pollution. At the same time, the existing collection device is very complicated to operate, takes a long time to operate, and affects the efficiency of care.

[0004] The inventor team is composed of front-line medical workers. In their long-term clinical work, they have been deeply troubled by the above-mentioned problems. They believe that it is necessary to improve the above-mentioned problems. After long-term theoretical analysis and combined with on-site practice, they have proposed a new care product that can be quickly fixed and has good sealing ability, which has a great improvement effect on fecal incontinence dermatitis. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose an anti-incontinence dermatitis feces collection device, which can be fixed by pressing once, can be completely conformed to the perianal area, has good sealing and high reliability, so as to solve the problems of complex operation, low nursing efficiency, poor fixation, poor conformability and leakage in the prior art.

[0006] The present invention is achieved through the following technical solutions:

[0007] The feces collection device for preventing incontinence dermatitis comprises a feces collecting tube, a feces collecting container and a fixer, wherein the fixer comprises a support cylinder, one end of the support cylinder is sealed and connected with the feces collecting tube, and the other end is provided with a support plane, and an extrusion arc is provided on the support plane and the side of the cylinder body, and the extrusion arc is used to stretch the perianal muscles to facilitate the perianal area to form an operating plane that fits the support plane, an annular groove is provided on the circumference of the support plane extending outward from the inner hole, and the annular groove is an annular blind hole extending from the support plane to the other end, and an annular piston and a pressure rod fixed to the annular piston are provided in the annular blind hole. The pressure rod extends along the annular groove toward the end of the feces collecting pipe and passes through it, and a pressing handle is arranged at the passing end. The annular piston divides the annular groove into an extrusion chamber and a piston chamber. The extrusion chamber is located at the opening end of the annular groove, and the piston chamber is located at the blind hole end of the annular groove. The extrusion chamber is provided with a deformable soft bag. The deformable soft bag is deformed under the extrusion action of the annular piston and forms a seal with the perianal area. The support plane is also provided with a plurality of negative pressure adsorption holes connected with the piston chamber. When the deformable soft bag is extruded, the support plane is negatively fixed with the perianal skin through the negative pressure adsorption holes.

[0008] Furthermore, the annular piston is connected to the piston chamber in a sliding and sealing manner.

[0009] Furthermore, 2 to 5 pressure rods are evenly distributed on the circle of the annular groove.

[0010] Furthermore, the pressure rod is provided with a locking nut between the pressing handle and the supporting tube.

[0011] Furthermore, any of the negative pressure adsorption holes is provided with a vent hole connected to the piston cavity.

[0012] Furthermore, an elastic cushion is provided on the support plane in the area of ​​the negative pressure adsorption hole.

[0013] Furthermore, the deformable soft capsule comprises a plastic outer film and plasticine wrapped and fixed in the outer film.

[0014] Furthermore, a negative pressure drainage device is provided on the feces collecting pipe.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention can stretch the perianal muscles by combining the support plane and the extrusion arc, and form an operation plane that fits the support plane, so that the perianal skin is in a stretched state and has a certain pressure bearing capacity, providing the possibility for subsequent operations.

[0017] 2. The present invention also uses a piston to squeeze the deformable soft capsule. Due to the deformability of the deformable soft capsule, it can adapt to different shapes, so as to conform to the perianal fold area and form a seal, effectively preventing the penetration of fecal fluid.

[0018] 3. The present invention also generates negative pressure adsorption while squeezing the deformed soft capsule, thereby fixing the support tube near the anus and offsetting the reaction force of the deformed soft capsule on the anus skin, thereby stabilizing the whole.

[0019] 4. The present invention provides a locking nut on the pressure rod, which can lock the pressure rod and the support tube after the seal is in place, thereby ensuring that the compression force and the clamping force are stable and continuous.

[0020] In summary, the present invention creatively proposes a fixing structure with positive and negative pressure extrusion molding, and the fixing is completed in one pressing operation. The operation is extremely simple and the actual effect is very significant. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0032] In the above description of the present invention, it should be noted that the terms "one side", "the other side", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0033] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0034] like Figure 1-6As shown, an embodiment of the present invention is provided: an anti-incontinence dermatitis feces collection device, including a feces collection tube 1 and a feces collection container 2. The feces collection tube is connected to the feces collection container to collect feces into the feces collection container. In particular, a fixer is provided in this embodiment. The fixer 3 includes a support tube 4. The support tube is a tube body with a central hole. One end of the tube body is sealed and connected to the feces collection tube to ensure that there is no leakage. A support plane 5 is provided at the other end of the tube body. The support plane is used to extrude the skin and muscle tissue around the anus into a plane. A fillet is provided between the support plane and the side of the tube body to form a smooth transition, which is an extrusion arc 6. The extrusion arc is used to stretch the peripheral muscles around the anus. The support plane acts on the perianal area at the same time, and forms an operating plane that fits the support plane in the perianal area. At this time, the operating plane has a certain surface tension, which provides the possibility for subsequent operations. In this embodiment, an annular groove 7 is provided on the supporting plane. The annular groove is provided on a circumference extending from the inner hole to the outside, and the annular groove is an annular blind hole extending from the supporting plane to the other end. An annular piston 8 and a pressure rod 9 fixed to the annular piston are provided in the annular blind hole. The pressure rod extends along the annular groove toward the end of the feces collecting pipe and passes through, and a pressing handle 10 is provided at the passing end. The annular piston divides the annular groove into an extrusion chamber 11 and a piston chamber 12. The extrusion chamber is located at the opening end of the annular groove, and the piston chamber is located at the blind hole end of the annular groove. A deformable soft bag 17 is provided in the extrusion chamber. The deformable soft bag is deformed under the extrusion action of the annular piston and forms a seal with the perianal area. A plurality of negative pressure adsorption holes 13 connected with the piston chamber are also provided on the supporting plane, and the negative pressure adsorption holes are all provided with vents 14, so as to keep the negative pressure adsorption holes connected with the piston chamber. When the deformable soft bag is squeezed, the supporting plane sucks out the gas through the vents to form negative pressure fixation with the perianal skin.

[0035] When the present embodiment is in use, the support plane end of the support tube is directed toward the patient's anus, and its center is aligned with the center of the anus, and the muscles around the anus are squeezed downward until the support plane fits with the skin around the anus to form an operating plane. The pressing handle is then pushed to move the pressing rod downward, thereby pushing the pressing rod to move. The movement of the pressing rod thereby pushes the annular piston to move, thereby pushing the deformable soft bag to move. As the movement continues, the deformable soft bag acts on the periphery of the anus and further deforms, fitting with the anal folds, and finally reaching a completely closed state. During this process, the volume of the piston cavity increases, and airflow enters from the negative pressure adsorption hole. When the support tube fits with the operating plane, gas cannot enter the negative pressure adsorption hole from the outside, thereby forming negative pressure. As the pushing continues, the negative pressure becomes greater and greater, and the force becomes stronger, thereby achieving the purpose of complete fixation.

[0036] The above process actually consists of two processes, namely, pressing the support tube and pressing the pressing rod. In fact, when the hand acts on the pressing handle, the support tube is also supported, so that a one-hand operation can be achieved, which is extremely simple to operate.

[0037] This fixing method adopts positive compression conformal sealing and reverse negative pressure adsorption fixation, thereby forming a self-adaptive fixation, which does not require adhesive fixation, improves its comfort, and is more convenient to disassemble. At the same time, this fixing method uses a deformable soft bag for sealing, and its sealing condition is a compression seal, which will not penetrate with the continuous seepage of fecal fluid. Its seal is more stable and lasting, and will not cause environmental pollution.

[0038] In this embodiment, the annular piston is provided with a sealing member so as to maintain a sliding sealing connection with the piston chamber.

[0039] The number of the pressure rods in this embodiment is not fixed and can be any value between 2 and 5. In this embodiment, 2 are selected.

[0040] In this embodiment, a locking nut 15 is provided between the pressing rod and the supporting tube. After the supporting tube is fixed, the locking nut is rotated and locked on the end face of the supporting tube. At this time, the pressure in the negative pressure chamber ensures that the supporting tube will not fall off, thereby being permanently and stably fixed to the perianal area.

[0041] In this embodiment, an elastic cushion 16, such as rubber, soft silicone, etc., is provided on the support plane in the negative pressure adsorption hole area, so that when the support tube is squeezed downward, it deforms and fully discharges the gas inside to generate negative pressure.

[0042] In this embodiment, the deformable soft bag includes a plastic outer film and plasticine wrapped and fixed in the outer film. The plasticine can be deformed into any shape, so as to form a conformal seal on the skin of the perianal folds. In this embodiment, it is wrapped with a plastic outer film mainly to prevent it from escaping from the extrusion cavity during use.

[0043] In order to prevent gas from being generated during the extrusion process, the plastic outer film of this embodiment does not advocate completely closing the plastic outer film, or at least has exhaust holes when it is closed.

[0044] In this embodiment, in order to facilitate the collection of fecal fluid, a negative pressure drainage device 18 is provided on the fecal collection pipe.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
