Description

Technical Field

[0001] This invention relates to the field of medical and nursing device technology, specifically to a fecal collection device for preventing incontinence-related dermatitis. Background Technology

[0002] There are currently several treatment options for fecal incontinence. The main approach involves securing the feces around the anus with adhesive, followed by negative pressure suction along the stool passage to remove the stool. While this method functionally achieves the goal of collecting stool, it still presents the following technical challenges:

[0003] The adhesiveness of adhesives primarily stems from intermolecular forces. When adhesive molecules fully wet the surface of the object being adhered to and maintain good contact, intermolecular interactions occur, with water playing a significant role in wetting the "adhesive molecules." However, for patients with fecal incontinence, prolonged and continuous leakage of feces inevitably leads to high perianal humidity, disrupting the adhesive environment and weakening its bonding ability, making it prone to detachment and affecting usability. Furthermore, the presence of perianal folds allows feces to easily seep through the gaps, causing perianal skin lesions and environmental pollution. Simultaneously, existing collection devices are very complex to operate, time-consuming, and impact nursing efficiency.

[0004] The inventors' team, comprised of frontline medical professionals, were deeply troubled by the aforementioned problems during their long-term clinical work. They believed it was necessary to improve these issues and, through extensive theoretical analysis and practical experience, proposed a novel nursing product that can quickly fix and provides excellent sealing, significantly improving fecal incontinence-related dermatitis. Summary of the Invention

[0005] In view of this, the purpose of this invention is to propose a fecal collection device for preventing incontinence dermatitis, which can be fixed with just one press, and can be perfectly conformed to the perianal area, with good sealing and high reliability, so as to solve the problems of complicated operation, low nursing efficiency, poor fixation, poor conformation and leakage in the prior art.

[0006] This invention is achieved through the following technical solution:

[0007] A fecal collection device for preventing incontinence-related dermatitis includes a collection tube, a collection device, and a fixing device. The fixing device includes a support cylinder, one end of which is sealed and connected to the collection tube, and the other end has a support plane. The support plane and the side of the cylinder have a compression arc, which expands the perianal muscles, facilitating the formation of an operating surface in the perianal area that conforms to the support plane. An annular groove is provided on the circumference of the support plane extending outward from the inner hole. The annular groove is an annular blind hole extending from the support plane to the other end. An annular piston and a pressure rod fixed to the annular piston are installed within the annular blind hole. The pressure rod extends along the annular groove towards the end of the collection pipe and passes through it, with a pressing handle provided at the protruding end. The annular piston divides the annular groove into a squeezing chamber and a piston chamber. The squeezing 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 squeezing chamber is provided with a deformable soft bladder. The deformable soft bladder deforms under the squeezing action of the annular piston, forming a seal with the perianal area. The supporting plane is also provided with multiple negative pressure suction holes communicating with the piston chamber. When the deformable soft bladder is squeezed, the supporting plane forms a negative pressure fixation with the perianal skin through the negative pressure suction holes.

[0008] Furthermore, the annular piston is slidably and sealed to the piston chamber.

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

[0010] Furthermore, a locking nut is provided between the pressing handle and the support cylinder of the pressure rod.

[0011] Furthermore, each of the aforementioned negative pressure adsorption holes is provided with a vent hole that communicates with the piston chamber.

[0012] Furthermore, the supporting plane is provided with an elastic pad in the negative pressure adsorption hole area.

[0013] Furthermore, the deformable soft capsule includes a plastic outer membrane and modeling clay wrapped and fixed inside the outer membrane.

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

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention uses a combination of a supporting plane and a squeezing arc to stretch the perianal muscles and form an operating plane that fits with the supporting plane, so that the skin around the anus is taut and has a certain pressure resistance, making subsequent operations possible.

[0017] 2. The present invention also uses a piston to compress a deformable soft capsule. Due to the deformability of the deformable soft capsule, it can adapt to different shapes, thereby conforming to the anal folds and forming a seal, effectively preventing the penetration of fecal matter.

[0018] 3. The present invention also generates negative pressure adsorption while compressing the deformable soft bladder, thereby fixing the support cylinder near the anus and counteracting the reaction force of the deformable soft bladder on the anal skin, thus making the whole stable.

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

[0020] In summary, this invention creatively proposes a fixing structure with positive and negative pressure extrusion molding, and the fixing is completed in a single pressing operation. Its operation is extremely simple and the actual effect is very significant. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[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 conventionally placed during use. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0034] like Figure 1-6As shown, an embodiment of the present invention provides a fecal collection device for preventing incontinence-related dermatitis, including a collection pipe 1 and a collection device 2. The collection pipe is connected to the collection device to collect fecal matter. In particular, this embodiment is provided with a fixator 3, which includes a support cylinder 4. The support cylinder is a tube with a central hole. One end of the tube is sealed to the collection pipe to ensure no leakage. The other end of the tube is provided with a support plane 5. The support plane is used to compress the skin and muscle tissue around the anus into a flat plane. A rounded corner is provided between the support plane and the side of the cylinder to form a smooth transition, which is a compression arc 6. The compression arc is used to stretch the muscles around the anus. The support plane also acts on the anal area and forms an operating plane in the anal area that fits with the support plane. At this time, the operating plane has a certain surface tension, which makes subsequent operations possible. In this embodiment, an annular groove 7 is provided on the supporting plane. The annular groove is provided on the circumference extending outward from the inner hole, 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 to the end of the collection pipe and passes through, and a pressing handle 10 is provided at the end of the passage. The annular piston divides the annular groove into a squeezing chamber 11 and a piston chamber 12. The squeezing 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 squeezing chamber is provided with a deformable soft bag 17. The deformable soft bag deforms under the squeezing action of the annular piston and forms a seal with the perianal area. The supporting plane is also provided with a plurality of negative pressure adsorption holes 13 communicating with the piston chamber, and each of the negative pressure adsorption holes is provided with a vent hole 14, thereby keeping the negative pressure adsorption hole communicating with the piston chamber. When the deformable soft bag is squeezed, the supporting plane draws out the gas through the vent hole and forms a negative pressure fixation with the perianal skin.

[0035] In this embodiment, the supporting flat end of the support cylinder faces the patient's anus, and its center is aligned with the center of the anus. The muscles around the anus are pressed down until the supporting flat end is in contact with the skin around the anus, forming an operating plane. Then, the pressing handle is pushed to move the pressing rod downwards, thereby moving the pressing rod. The movement of the pressing rod, in turn, moves the annular piston, which in turn moves the deformable soft bag. As the movement continues, the deformable soft bag acts on the anal periphery and further deforms, fitting into the anal folds, ultimately achieving a completely sealed state. During this process, the volume of the piston chamber increases, and airflow enters from the negative pressure adsorption hole. When the support cylinder is in contact with the operating plane, gas cannot enter the negative pressure adsorption hole from the outside, thus forming a negative pressure. As the pressing continues, the negative pressure increases, and the force becomes stronger, thereby achieving the purpose of complete fixation.

[0036] The process described above actually involves only two steps: pressing the support cylinder and pressing the lever. In reality, when the hand applies pressure to the lever, it also holds the support cylinder, allowing for a single-handed operation that is extremely simple.

[0037] This fixing method uses positive compression conformal sealing and reverse negative pressure adsorption fixing to form a self-adaptive fixation, which does not require adhesive fixation, thus improving comfort and making disassembly easier. At the same time, because this fixing method uses a deformable soft capsule for sealing, the sealing condition is compression sealing, which will not seep through as fecal fluid continues to leak out, making the seal more stable and durable and not causing environmental pollution.

[0038] In this embodiment, the annular piston is provided with a seal to maintain a sliding and sealed connection with the piston cavity.

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

[0040] In this embodiment, a locking nut 15 is provided between the pressing handle and the support cylinder on the pressure rod. After the support cylinder is fixed, the locking nut is rotated and locked to the end face of the support cylinder. At this time, the pressure of the negative pressure chamber is guaranteed, and the support cylinder will not fall off, thus permanently and stably fixing it to the perianal area.

[0041] In this embodiment, an elastic pad 16, such as rubber or soft silicone, is provided on the support plane in the negative pressure adsorption hole area. When the support cylinder is pressed down, it deforms and fully discharges the gas inside, generating negative pressure.

[0042] In this embodiment, the deformable soft capsule includes a plastic outer membrane and modeling clay, etc., wrapped and fixed inside the outer membrane. The modeling clay can be deformed into any shape, thereby forming a conformal seal on the perianal skin folds. In this embodiment, it is wrapped with a plastic outer membrane mainly to prevent it from detaching from the compression chamber during use.

[0043] To prevent gas generation during the extrusion process, the plastic outer film in this embodiment is not recommended to be completely sealed, or at least have venting holes when sealed.

[0044] In this embodiment, a negative pressure drainage device 18 is installed on the stool collection pipe to facilitate the collection of stool fluid.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
