Description

Technical Field

[0001] The invention relates to the technical field of colorectal tumor postoperative care, in particular to a leakage-proof clean ostomy bag for colorectal tumor postoperative care. Background Art

[0002] After existing colorectal tumor surgery, a base is attached to the stoma, and then a fecal bag is inserted into the base to collect feces. Since the fecal bag is heavy when filled with feces, it is easy to pull the connection between the fecal bag and the base to deform and cause leakage. In addition, the fecal bag is directly exposed to the outside and is easily squeezed, resulting in excessive pressure at the connection and leakage. The leaked fecal liquid directly flows out and contaminates clothing.

[0003] To this end, Chinese patent application number CN218852933U discloses a "leakage-proof clean ostomy bag for colorectal tumor surgery." Its main structure includes a protective shell and a stoma base. The protective shell is a spherical shell structure, and connecting belts are provided on the left and right sides of the protective shell. The connecting belts on both sides are wrapped around the user's waist and fixedly connected by strap buckles. A baffle is fixedly connected to the lower end of the inner side of the protective shell, and a fecal bag is placed between the protective shell and the baffle. A docking plug is provided on the inner side of the upper end of the fecal bag. The stoma base is adhered to the patient's skin around the fistula opening with medical tape. The protective shell fixed by the belt supports and protects the fecal bag inside, effectively preventing leakage caused by pulling deformation at the mating point of the docking plug and docking socket. The spherical shell structure of the protective shell can also provide support and protection for the front of the fecal bag, effectively reducing the impact and extrusion on the fecal bag, further improving the anti-seepage effect of the device. At the same time, the provision of the protective shell can receive the leaked liquid in the event of accidental leakage from the docking plug and docking socket, preventing the leaked liquid from contaminating clothing and facilitating subsequent cleaning.

[0004] However, when the above-mentioned anti-leakage clean ostomy bag after colorectal tumor surgery is actually working, the gravity on the bag will eventually be concentrated on the stoma base and the patient's skin around the stoma. According to the torque principle, the pressure caused by the feces will produce a downward pressure on the belt toward one side. The above-mentioned belt is bound around the patient's stoma at a balanced height, and its ability to prevent the bag from falling off is relatively limited. Summary of the Invention

[0005] In response to the deficiencies of the existing technology, the present invention provides a leak-proof and clean ostomy bag for colorectal tumor surgery, in which the elastic bandage is higher than the horizontal position of the patient's stoma. Combined with the force torque exerted by the bag on the area around the stoma, the force can be concentrated on one side of the elastic bandage located on the bag. The transparent plastic sheet provided on this side can then have a resistance effect on the patient's skin, thereby effectively increasing the pre-tightening force on the bag, thereby preventing feces and liquid from leaking outward along the skin around the stoma, thereby solving the above-mentioned technical problems.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a leak-proof and clean ostomy bag for colorectal tumor surgery, comprising an elastic bandage that can be put on the outside of a patient's limb, an elastic belt locking mechanism, the interior of which is provided with a hollow buckle that can be put on the outside of the elastic bandage belt, a rectangular locking plate that is placed inside the hollow buckle and can achieve an extrusion-type locking action on the elastic bandage belt, and a coil spring that provides the pressure required for the locking action on the rectangular locking plate; and an adhesive feces collection mechanism, the interior of which is provided with a protective cover that can be adhered to the skin around the patient's stoma and connected to the bottom of the elastic bandage belt, and a feces bag that can be placed at the discharge port of the protective cover and is used to store feces and liquids.

[0007] Preferably, the elastic bandage is made of a textile material having elastic stretchability and breathability.

[0008] Preferably, the elastic belt locking mechanism also includes two rectangular movable plates, the hollow buckle is provided with two symmetrical belt through-holes that pass through the elastic bandage belt body, the center of the hollow buckle is provided with a rectangular component movable cavity, and the hollow buckle is provided with horizontal limit flow notches at the bottom and top ends of the rectangular component movable cavity, respectively. The hollow buckle is provided with two rectangular component through-holes connecting the bag body through-hole and the rectangular component movable cavity. The hollow buckle is provided with two longitudinal rectangular movable plates located in the rectangular component movable cavity and capable of horizontally moving along the rectangular component movable cavity. The two rectangular movable plates are fixedly installed with two coil springs in a compressed state at opposite ends. The rectangular movable plate is provided with a rectangular locking plate with an integral structure therewith and passing through the rectangular component through-hole at the end facing the rectangular component through-hole, and the top and bottom ends of the rectangular movable plate are fixedly installed with limit movable rods passing through the horizontal limit flow notches.

[0009] Preferably, when one end of the rectangular locking plate contacts the surface of the elastic bandage, the rectangular movable plate still has a range of movement in the horizontal movement direction.

[0010] Preferably, the elasticity of the coil spring on the rectangular movable plate is sufficient to enable the rectangular locking plate to lock the belt body of the elastic bandage.

[0011] Preferably, the adhesive feces collection mechanism also includes an annular embedded body that can be fixed to the bottom of the elastic bandage belt body, and a protective cover is installed on the bottom of the annular embedded body through a transparent plastic sheet. A transparent adhesive bag is fixedly installed on the end of the protective cover facing the elastic bandage. A fistula hole that can be placed around the fistula opening is provided in the center of the protective cover, and a sleeve shell that can be placed on the discharge port of the protective cover is fixedly installed on the port of the feces bag.

[0012] Compared with the existing technology, the present invention provides a leak-proof and clean ostomy bag for colorectal tumor surgery, which has the following beneficial effects:

[0013] The elastic bandage is made higher than the horizontal position of the patient's stoma. Combined with the force torque of the fecal bag on the area around the stoma, the force can be concentrated on the side of the elastic bandage located on the fecal bag. The transparent plastic sheet provided on this side then has a resistance effect on the patient's skin, thereby effectively increasing the pre-tightening force on the fecal bag and preventing feces and liquid from leaking outward along the skin around the stoma.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 and Figure 2 A leak-proof and clean ostomy bag for colorectal tumor surgery includes an elastic bandage 1 that can be put on the outside of the patient's limb. The elastic bandage 1 is made of a textile material with elastic extensibility and breathability. The elastic bandage 1 is put on the outside of the patient's limb, and the elastic bandage 1 is placed above the patient's stoma. Then the stoma hole 33 in the protective cover 31 is put on the periphery of the patient's stoma. Finally, the sleeve shell 36 is installed on the discharge port of the protective cover 31, and then the transparent adhesive bag 32 is adhered to the skin around the stoma.

[0024] In order to adjust the tension of the elastic bandage 1 so that the device can be worn according to actual conditions, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , it is necessary to set up an elastic belt locking mechanism 2, which is provided with a hollow buckle 21 that can be placed on the outside of the elastic bandage 1 belt body, a rectangular locking plate 27 placed inside the hollow buckle 21 and capable of realizing an extrusion-type locking action on the elastic bandage 1 belt body, and a coil spring 29 that provides the rectangular locking plate 27 with the pressure required for the locking action. A force toward the symmetric plane is applied to the limiting movable rod 28, so that the two rectangular movable plates 26 approach each other. At this time, the pressure of the rectangular locking plate 27 on the elastic bandage 1 belt body is reduced until it drops to zero. The range of the elastic bandage 1 can be adjusted, thereby adjusting the elastic force of the elastic bandage 1 bound to the patient's limb, and the device can be worn according to actual conditions.

[0025] For the specific structure of the elastic belt locking mechanism 2, please refer to Figure 3 、 Figure 4 and Figure 5, also includes two rectangular movable plates 26, the interior of the hollow buckle 21 is provided with two symmetrical belt body through-holes 22 that pass through the elastic bandage 1 belt body, the center of the hollow buckle 21 is provided with a rectangular component movable cavity 24, the hollow buckle 21 is provided with a horizontal limit flow notch 23 at the bottom and top ends of the rectangular component movable cavity 24, the interior of the hollow buckle 21 is provided with two rectangular component through-holes 25 that communicate with the bag body through-hole 22 and the rectangular component movable cavity 24, the hollow buckle 21 is provided with two longitudinal rectangular movable plates 26 that can move horizontally along the rectangular component movable cavity 24, the two rectangular movable Two compressed coil springs 29 are fixedly installed at the opposite ends of the plate 26. The rectangular movable plate 26 is provided with a rectangular locking plate 27 at the end facing the rectangular part through-hole 25, which is an integral structure with the plate 26 and passes through the rectangular part through-hole 25. The top and bottom ends of the rectangular movable plate 26 are fixedly installed with limiting movable rods 28 that pass through the horizontal limiting flow gap 23. When one end of the rectangular locking plate 27 abuts against the surface of the belt body of the elastic bandage 1, the rectangular movable plate 26 still has a moving stroke range in the horizontal movement direction. The elasticity of the coil spring 29 on the rectangular movable plate 26 is sufficient to enable the rectangular locking plate 27 to lock the belt body of the elastic bandage 1.

[0026] In order to improve the stability of the stool bag 37 and the protective cover 31, please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , it is necessary to set up an adhesive feces collection mechanism 3, which is provided with a protective cover 31 that can be adhered to the skin around the patient's fistula opening and connected to the bottom of the elastic bandage 1, and a feces bag 37 that can be placed at the discharge port of the protective cover 31 and is used to store feces and liquids. Since the transparent plastic sheet 34 has a longitudinal height tension limiting function on the feces bag 37 and the protective cover 31, the feces bag 37 and the protective cover 31 can have a certain tensile resistance, thereby improving the stability of the feces bag 37 and the protective cover 31.

[0027] For the specific structure of the adhesive feces collecting mechanism 3, please refer to Figure 6 and Figure 7 , and also includes an annular embedded body 35 that can be fixed to the bottom of the elastic bandage 1. The bottom of the annular embedded body 35 is installed with a protective cover 31 through a transparent plastic sheet 34. The protective cover 31 is fixedly installed with a transparent adhesive bag 32 at the end facing the elastic bandage 1. The center of the protective cover 31 is provided with a fistula hole 33 that can be placed around the fistula. The port of the fecal bag 37 is fixedly installed with a sleeve shell 36 that can be placed on the discharge port of the protective cover 31.

[0028] During use, the elastic bandage 1 is placed on the outside of the patient's limb, with the elastic bandage 1 positioned above the patient's stoma. The stoma-releasing hole 33 in the protective cover 31 is then placed around the periphery of the patient's stoma. Finally, the stoma-releasing shell 36 is installed on the discharge port of the protective cover 31, and the transparent adhesive bag 32 is adhered to the skin around the stoma. When the tension of the elastic bandage 1 needs to be adjusted, a force is applied to the limiting movable rod 28 toward the symmetric plane, causing the two rectangular movable plates 26 to move closer together. At this time, the pressure of the rectangular locking plate 27 on the elastic bandage 1 is reduced until it reaches zero. The range of the elastic bandage 1 can be adjusted, thereby adjusting the elastic force of the elastic bandage 1 bound to the patient's limb. When the device is in operation, the transparent plastic sheet 34 exerts a longitudinal tension limit on the fecal bag 37 and the protective cover 31, which can provide the fecal bag 37 and the protective cover 31 with a certain degree of tensile resistance, thereby improving the stability of the fecal bag 37 and the protective cover 31.

[0029] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
