Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and specifically relates to a stoma protective patch. Background Art

[0002] Enterostomy is a relatively common surgery, which usually requires pulling out a section of the intestine in the abdominal cavity and excreting feces through an opening in the skin of the abdominal wall. Usually, a special stoma bag is needed to collect urine and feces. Especially when suffering from digestive tract diseases such as intestinal obstruction, familial adenomatous polyposis, bladder tumors, congenital anal atresia, colon cancer and intestinal malignant tumors, this surgery is needed to treat the disease, which can improve the disease and prevent the disease from continuing to develop. For a period of time after the operation, the patient's stoma will excrete pure liquid excrement, and at this time, a stoma bag is needed to collect the liquid excrement discharged through the stoma.

[0003] At present, the colostomy bags used by patients in clinical practice are mainly two-piece types. Liquid excrement may leak out from the side of the colostomy bag due to changes in body position, the colostomy base plate not being firmly glued, the colostomy bag and the base plate not being tightly connected, wound exudate soaking the colostomy base plate, etc., requiring medical staff to re-instruct on how to replace the colostomy bag. Most postoperative colostomy patients need the cooperation of their family members to learn the process of changing the colostomy bag multiple times.

[0004] Therefore, a device is designed that can absorb liquid excrement on the patient's body surface without using a base plate. The device is specifically a stoma protective patch. Utility Model Content

[0005] In order to overcome the problems raised in the background technology, the utility model adopts the following technical solutions:

[0006] A stoma protection patch, comprising an executive part and a fixing patch; the executive part comprises a waterproof layer, a breathable layer and an adsorption layer, the breathable layer is bonded to the waterproof layer, the adsorption layer is bonded to the breathable layer, and the adsorption layer and the waterproof layer are respectively connected to two end surfaces of the breathable layer; the fixing patch is connected to the executive part, the fixing patch has a sticky end surface, the sticky end surface and the adsorption layer are both away from the waterproof layer, and the sticky end surface is bonded to the patient's skin surface.

[0007] Furthermore, the waterproof layer, the breathable layer and the adsorption layer are all flexible, so that when the execution part is applied to the patient's body surface, it can be in contact with, squeezed and deformed by the patient's stoma, thereby preventing damage to the patient's stoma.

[0008] Furthermore, the execution portion has a recessed portion, and the recessed direction of the recess is opposite to the direction of the adhesive end face. When the adhesive end face is bonded to the surface of the patient's skin, a cavity is formed between the recessed portion and the patient's skin. After the liquid excreta in the stoma is discharged, it fully contacts the adsorption layer and diffuses outward with the contact position between the stoma and the adsorption layer as the center of the circle. The liquid excreta solidifies on the adsorption layer, and the cavity between the adsorption layer and the skin can provide expansion space for the adsorption layer to prevent the adsorption layer from squeezing the patient's skin after expansion.

[0009] Furthermore, a non-stick layer is connected to the sticky end surface, and the non-stick layer is connected to the sticky end surface through surface tension, so as to prevent the sticky end surface from being contaminated.

[0010] Furthermore, the non-stick layer is provided with an easy-tear line, and the number of the easy-tear line is at least one. The easy-tear line helps the user to quickly find the fulcrum for grasping the non-stick layer so as to peel the non-stick layer off the sticky end surface.

[0011] Furthermore, the width of the sticky end surface is at least 10 mm, the width of the non-stick layer is not less than the width of the sticky end surface, and the non-stick layer can completely cover the sticky end surface when connected to the sticky end surface.

[0012] Furthermore, the adsorption layer is made of polymer water-absorbent resin and medical absorbent cotton.

[0013] Furthermore, when the fixing patch is laid flat on a plane, the outline of the waterproof layer is a quadrilateral, the waterproof layer has the same shape as the breathable layer, and the breathable layer has the same shape as the adsorption layer.

[0014] Furthermore, the air permeable layer has micropores.

[0015] Furthermore, the waterproof layer is made of polyurethane.

[0016] Beneficial effects of the utility model:

[0017] By providing a fixing patch that can be directly attached to the skin surface around the patient's stoma, the execution part is positioned at the patient's stoma, thereby being able to replace the stoma bag and stoma chassis with complex structure and heavy weight, and not easy to fall off during use; by providing an adsorption layer made of a high molecular water-absorbent resin, liquid excrement discharged into the receiving space through the stoma can be absorbed in a timely and efficient manner, thereby preventing the liquid from escaping from the receiving space and corroding the patient's skin, and the adsorption layer has the function of absorbing ammonia, thereby being able to reduce the odor discharged from the receiving space.

[0027] In some embodiments of the present application, Figure 1-4 As shown, the execution part 1 has a recess 14, and the recess 14 is in the opposite direction to the sticky end face 21. When the sticky end face 21 is bonded to the patient's skin surface, a cavity is formed between the recess 14 and the patient's skin. After the liquid excreta in the stoma is discharged, it is in full contact with the adsorption layer 13 and diffuses outward with the contact position between the stoma and the adsorption layer 13 as the center. The liquid excreta solidifies on the adsorption layer 13. The cavity between the adsorption layer 13 and the skin can provide expansion space for the adsorption layer 13 to prevent the adsorption layer 13 from squeezing the patient's skin after expansion.

[0028] In some embodiments of the present application, Figure 1-4 As shown, a non-stick layer 22 is connected to the sticky end surface 21 , and the non-stick layer 22 is connected to the sticky end surface 21 through surface tension, so as to prevent the sticky end surface 21 from being contaminated.

[0029] In some embodiments of the present application, Figure 1-4 As shown, an easy-tear line 221 is provided on the non-stick layer 22, and the number of the easy-tear line 221 is at least one. The easy-tear line 221 helps the user to quickly find the fulcrum for grasping the non-stick layer 22 so as to peel the non-stick layer 22 from the sticky end surface 21.

When the liquid excrement in the stoma is discharged, it is first absorbed by the medical cotton wool and then enters the polymer absorbent resin. After absorbing the liquid excrement, the polymer absorbent resin becomes gel-like, thereby preventing the adsorbed liquid excrement from being squeezed out, thereby effectively avoiding leakage and pollution of other liquid excrement. The highly absorbent resin also has ammonia absorption property, which can effectively absorb the odor emitted by the liquid excrement.

[0033] In some embodiments of the present application, Figure 1-4 As shown, when the fixing patch 2 is laid flat on a plane, the outline of the waterproof layer 11 is a quadrilateral, the waterproof layer 11 has the same shape as the breathable layer 12, and the shape of the breathable layer 12 is the same as the shape of the adsorption layer 13. Specifically, the outline of the waterproof layer 11 is a rectangle, a square or a parallelogram.

[0034] In some embodiments of the present application, Figure 1-4 As shown, the material of the breathable layer 12 is a breathable film with micropores, which allows gas to pass through while preventing liquid exchange on both sides, thereby having good air permeability. The breathable film is specifically polyethylene obtained by adding CaCO3 and stretching, which has a microporous structure. The material of the waterproof layer 11 is polyurethane.
