Description

Technical Field

[0001] The utility model belongs to the technical field of medical consumables, and particularly relates to an improved ostomy bag. Background Art

[0002] A stoma is generally used to treat lesions in the patient's rectum, bladder and other parts of the body (such as rectal cancer, bladder cancer, intestinal obstruction, etc.). In order to save the patient's life, the doctor will surgically remove the lesion. For example, rectal cancer will remove the rectum and anal canal, and bladder cancer will remove the bladder. Depending on the specific location of the lesion, a stoma is made on the left or right side of the patient's abdomen. The stoma can achieve intestinal decompression, reduce obstruction, protect the anastomosis or damage of the distal intestinal tract, promote the recovery of intestinal and urinary system diseases, and even save the patient's life. The patient's feces or urine needs to be discharged involuntarily from the body through the stoma. Since the stoma lacks sphincter function, such patients need to stick a stoma bag at the stoma to collect excrement.

[0003] The stoma bag does not need to be changed every day. Generally, it is changed every 2 to 5 days. The specific time can be determined based on whether there is leakage and whether the skin at the stoma of the patient is normal. The use time can also be extended based on the formation of the stool. Therefore, it is very important to clean the stoma bag and the excrement inside it conveniently during use. After searching, the Chinese patent with the patent number CN215020143U and the name of the improved stoma bag has an extension tube connected to the lower part of the stoma bag. The extension tube is provided with a valve port, which can be connected to a disposable flushing tube to directly inject the cleaning water into the stoma bag. After cleaning, the mixture of excrement and cleaning water is directly extracted with a disposable flushing tube.

[0004] The above-mentioned prior art can solve the problem of flushing the ostomy bag. The thin and mushy excrement of the patient can be extracted through a disposable flushing tube. However, it is very difficult to directly extract the viscous or even formed excrement of the patient after flushing, which will cause the risk of difficulty in extraction or even clogging the discharge tube. Utility Model Content

[0005] In view of the problems existing in the above-mentioned prior art, the present invention proposes an improved ostomy bag to solve the problem of discharge of the viscous and formed excrement of the above-mentioned patients.

[0006] The connection port provided at the bottom of the ostomy bag is connected to the double-layer plugging component, and the double-layer plugging component includes an upper sealing cover and a lower sealing plug. The lower sealing plug can be connected to the connecting pipe of the negative pressure device. Combined with the filter screen at the connecting port, the patient's formed stool and watery stool can be discharged separately. The inside of the ostomy bag can be cleaned and discharged through a disposable flushing tube connected to an extension tube. It is easy to operate and has a simple structure. It can effectively protect the perianal area of ​​​​diarrhea patients, reduce the incidence of incontinence dermatitis, and is convenient for collecting various types of formed or unformed stools. At the same time, it can reduce the workload and discomfort of nursing.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] An improved ostomy bag comprises a bag body, a discharge part and a flushing part, wherein:

[0009] The discharge part is arranged at the bottom of the bag body, and includes a connection port and a double-layer blocking component. The double-layer blocking component is arranged below the connection port and is used to classify and discharge the formed and unformed excrement blocked in the bag body;

[0010] The flushing part is arranged below the bag body.

[0011] In order to achieve the above purpose, further, the bag body is a bag body with an opening downward, and a circular bottom plate is provided on the side of the bag body close to the skin, and a plurality of circles of shear holes with increasing diameters are provided on the bottom plate. Adhesive is provided on the outer periphery of the bottom plate, and the diameter range of the plurality of circles of shear holes is 15~60mm.

[0012] A further preferred scheme of the above scheme is: a double-layer sealing assembly is arranged below the connecting port, the double-layer sealing assembly comprises an upper sealing cover and a lower sealing plug, the upper sealing cover and the connecting port are connected to each other by a connecting belt, an extension tube is arranged at the center of the upper sealing cover, the lower sealing plug is connected to the bottom of the extension tube, and a layer of filter net is also arranged on the inner wall of the upper sealing cover for separating the formed excrement of the patient.

[0013] A further preferred embodiment of the above scheme is that the flushing part includes an extension tube and a valve opening, the extension tube is arranged at the neck below the bag body, the lower end of the extension tube is the valve opening, the valve opening is cooperated and connected with the disposable flushing tube, and a piston is provided on one side of the valve opening for closing the valve opening.

[0014] By adopting the above technical scheme, the utility model has the following beneficial effects: when discharging the excrement in the bag body, if all of them are discharged at once through the discharge port at the bottom of the bag body, since the connecting pipe of the negative pressure device is a relatively long flexible hose, the pipeline is very easy to bend, and when discharging the patient's formed feces, it may cause internal blockage due to the bending of the pipeline, affecting the cleaning effect. Therefore, the utility model is provided with a double-layer sealing component, which is used to discharge and collect the patient's formed and unformed excrement separately.

[0015] 1. The double-layer sealing component includes an upper sealing cover and a lower sealing plug. After opening the lower sealing plug, a connecting tube connected to the negative pressure device is connected to the extension tube to discharge the patient's rotten stool, watery stool or liquid flushed by the disposable flushing tube;

[0016] 2. For a small amount of formed stool from the patient, it can be collected at the connection port after opening the upper cover, which can effectively prevent the patient's formed excrement from blocking the connecting tube and causing it to be unable to be discharged.

The excrement enters the double-layer plugging component through the connecting port 21 at the lower end of the bag body 11. The loose and rotten excrement enters the upper cover 23 and the lower plug 24 through the filter screen 232 and is then extracted through the negative pressure device 6. Most patients have loose and viscous stools. During the rehabilitation process, formed stools may occasionally be produced. At this time, the formed excrement is separated above the upper cover 23 by the filter screen 232. When necessary, the upper cover 23 is opened and collected. According to the shape of the patient's excrement, the stoma bag can be replaced every 2-5 days. Before replacement, the inside of the bag body 11 of the stoma bag needs to be cleaned regularly. The disposable flushing tube 4 is connected to the valve port 32. After the inside of the bag body 11 is cleaned, the loose and rotten excrement and the cleaning water are discharged through the lower plug 24.
