Description

TECHNICAL FIELD

[0001] The utility model relates to medical appliance technical field especially, relates to a fistulization bag. BACKGROUND

[0002] Referring to the five ladder of nutrition therapy, when the patient cannot eat orally, enteral nutrition is the preferred nutrition therapy, and is more easily absorbed by the human body. However, the reflux of enteral nutrition is a common problem in nursing work, especially for ileostomy, because of its large discharge capacity, the problem of reflux is more prominent. Usually, a fistulization bag is fixed outside the stoma to collect the exudate and reflux liquid of the stoma, so as to ensure the dryness of the skin around the stoma and prevent the occurrence of stoma dermatitis. The nutrition tube needs to pass through the fistulization bag, and the integrity of the fistulization bag also needs to be ensured.

[0003] At present, most of them make a "cross" cut on the fistulization bag, pass the nutrition tube out of the cross hole, and then use adhesive to fix it in a ring shape. However, the replacement cycle of the nutrition tube is 1-3 months, and the fistulization bag needs to be replaced every day. Each time the fistulization bag is replaced, the adhesive needs to be removed, which is time-consuming and laborious, and repeated removal and replacement can cause the nutrition tube to move, which can increase the discomfort of the patient, and even there is a risk of tube falling out. In addition, the commonly used nutrition tube has two lumen tubes and three lumen tubes, and the volume of the tail end of the nutrition tube increases the difficulty of passing through the cross cut.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] This embodiment provides a stoma bag for collecting exudate and reflux fluid from the stoma, with a feeding tube 100 inserted through the stoma.

[0035] like Figs. 1 to 3 As shown, the stoma bag includes a stoma bag body 1 and a fixing component 2. The stoma bag body 1 is fixed at the stoma and has a fixing hole. The fixing component 2 includes a connector 21 and a sealing component 22. The connector 21 is fixed to one side of the stoma bag body 1 and communicates with the fixing hole. The feeding tube 100 passes through the connector 21, and the radial dimension of the connector 21 is larger than the radial dimension of the feeding tube 100. The sealing component 22 includes two pistons 221 located on both sides of the feeding tube 100. The side of the two pistons 221 furthest from each other abuts against the inner wall of the connector 21 to achieve relative fixation between the stoma bag body 1 and the feeding tube 100, thereby improving the patient's comfort. When the stoma bag needs to be replaced, the sealing component 22 is removed, and the stoma bag body 1 is taken off. Then, the feeding tube 100 is passed through the fixing hole of the new stoma bag body 1, and the new stoma bag body 1 is fixed at the stoma. The entire replacement process is simple and convenient, and does not require contact with the feeding tube 100, which can effectively improve the patient's comfort. Whether the feeding tube 100 is a two-lumen tube or a three-lumen tube, it can achieve good compatibility between the stoma bag body 1 and the feeding tube 100.

[0036] Specifically, the stoma bag is adhered to the stoma. Furthermore, in this embodiment, the feeding tube 100 is a two-lumen tube.

[0037] Optionally, the connector 21 is tubular to better fit the fixing hole on the stoma bag body 1, and also facilitates the passage of the feeding tube 100.

[0038] Optionally, such as Fig. 2 As shown, each side of the piston component 221 facing each other is provided with an arc-shaped groove 222, and the feeding tube 100 abuts in the arc-shaped groove 222 to further improve the stability of the relative fixation between the feeding tube 100 and the stoma bag body 1, and ensure the patient's comfort.

[0039] Optionally, the piston component 221 is made of an elastic material. Since the elastic material itself has a certain degree of elasticity, on the one hand, it can ensure that the piston component 221 is stably attached between the outer wall of the nutrient tube 100 and the inner wall of the connector 21; on the other hand, it can facilitate the installation and disassembly of the piston component 221.

[0040] For example, the piston 221 is made of rubber material, which is easy to use and inexpensive.

[0041] Optionally, the size of the piston 221 gradually increases in the direction away from the stoma bag body 1. That is, the sealing member 22 is generally conical, which facilitates installation and provides a good sealing and fixing effect.

[0042] Optionally, each piston 221 is provided with an operating part on the side away from the stoma bag body 1, so as to facilitate medical staff to pick up the piston 221 and improve operating efficiency.

[0043] For example, the operating part is a protrusion protruding from the outside of the piston member 221.

[0044] Optionally, the stoma bag body 1 is provided with a waste discharge port, and a waste discharge port cover is provided at the waste discharge port. Specifically, the waste discharge port cover is screwed onto the waste discharge port, or the waste discharge port cover is snapped onto the waste discharge port. The above configuration allows the exudate and reflux fluid collected in the stoma bag body 1 to be discharged through the waste discharge port, realizing the recycling of the stoma bag.

[0045] Optionally, the stoma bag body 1 is provided with a handle to facilitate taking the stoma bag body 1.

[0046] Optionally, a flexible layer is provided on the outer side of the stoma bag body 1. The flexible layer is made of a flexible, skin-friendly material. The patient's skin around the stoma comes into contact with the flexible layer, which can further improve the patient's comfort.

[0047] For example, the flexible, skin-friendly material is cotton, which is soft, comfortable, can come into direct contact with human skin, and is durable.

[0048] Optionally, the stoma bag also includes a sealing cap 3, which is screwed onto the connector 21. With this configuration, when the patient is in the intermittent period of enteral nutrition, it is not necessary to insert the feeding tube 100; the sealing cap 3 can be screwed onto the connector 21, preventing the stoma from being directly exposed. When it is necessary to insert the feeding tube 100, the sealing cap 3 can be removed for insertion.

[0049] Specifically, in this embodiment, referring to Fig. 3 Multiple protrusions are provided on the outer side of the sealing cap 3 along the circumference to increase the friction between the sealing cap 3 and the hands of medical staff, making it easier to screw the sealing cap 3.

[0050] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
