Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a disposable anal canal negative pressure drainage device. Background Art

[0002] Fecal incontinence is a pathological phenomenon in which the patient cannot control the spontaneous discharge of feces due to damage to the anus or its related nerves. Common causes include intestinal infection, intestinal flora imbalance, anal sphincter dysfunction or damage, nerve disorder or damage, congenital diseases, etc. The most common nursing complication of fecal incontinence is incontinence dermatitis, which is mainly caused by frequent irritation of the perianal area and perineum by feces, resulting in itching, discomfort, skin ulceration and subsequent infection. The occurrence of incontinence dermatitis aggravates the patient's condition, increases the economic burden on the family members, and increases the nursing workload.

[0003] At present, the commonly used nursing methods for patients with fecal incontinence at home and abroad include: using disposable nursing pads (including diapers), built-in tampons for anal insertion, one-piece ostomy bags, etc., but they all have certain defects, such as: they cannot effectively protect the skin around the anus, cannot accurately observe and record the characteristics and amount of stool, etc., and the nursing workload is large. Utility Model Content

[0004] The utility model aims to provide a disposable anal canal negative pressure drainage device, which utilizes an airbag-equipped, porous, extended anal canal connected to a negative pressure drainage device for continuous suction to solve the nursing problem of fecal incontinence, thereby protecting the patient's perianal skin, more accurately recording the amount of stool, reducing nursing workload, and improving nursing quality.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Through the cooperation of the disposable negative pressure device and the anal canal, the feces of patients with fecal incontinence can be discharged into the disposable negative pressure device through the anal canal due to the negative pressure. Compared with existing nursing pads, tampons and other methods, the expansion component can better fit the patient's buttocks and effectively protect the perianal skin. The disposable negative pressure device can also record information such as stool characteristics and quantity more accurately, and provide effective care for patients.

[0008] The utility model is further optimized, the expansion component includes an expansion chamber, an air injection tube and an air injection tube plug, the expansion chamber is fixedly connected to the anal canal, one end of the air injection tube is fixedly connected to the expansion chamber, and the other end of the air injection tube is detachably provided with an air injection tube plug.

[0010] By pressing the space inside the supporting spring compressor, a negative pressure environment is created. The relatively simple disposable negative pressure device and anal tube structure not only saves production costs, but also allows for a use-and-replace method, avoiding infection caused by incomplete cleaning and making it more hygienic.

[0011] The utility model is further optimized to include a buttocks patch, an adhesive portion is provided on the edge of the bottom surface of the buttocks patch, and a hole for the anal canal and the air injection tube to pass through is provided at the center of the buttocks patch.

[0012] The buttock patch can more effectively collect feces from patients with fecal incontinence, more effectively prevent the front end of the anal canal inserted into the anus from falling off, enhance the effect of negative pressure adsorption, and further prevent the expansion chamber from not sealing in place, avoiding soiling of the bed and clothing.

[0013] As a further optimization for the utility model, the diameter of the anal canal is between 7.3 mm and 9 mm, and the length of the anal canal is 1 m.

[0014] As a further optimization for the utility model, there are 5 suction ports, which are alternately arranged on both sides at a distance of 1 cm, 3 cm, 5 cm, 7 cm and 9 cm from the top component, and the diameter of the suction ports is between 4.8 mm and 6 mm.

[0017] The hemispherical top component and the multiple grooves arranged on the inner wall thereof can smoothly deliver the anal canal to the designated position.

[0018] As a further optimization for the utility model, the expansion chamber can withstand a pressure between 25 mmHg and 30 mmHg.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] The utility model can make the feces of patients with fecal incontinence be discharged into the disposable negative pressure device through the anal canal due to the negative pressure effect, and the expansion component is closely attached to the inner wall of the anus after inflation, so that the anal canal is not easy to fall off and the fecal fluid will not flow out. Compared with the existing nursing pads, tampons and other methods, it can better fit the patient's anus, effectively protect the perianal skin, and prevent the patient from developing incontinence dermatitis due to long-term liquid soaking of the buttocks. The disposable negative pressure device can also more accurately record information such as stool properties and quantity, thereby achieving effective care for the patient. Therefore, the utility model avoids the problem that the commonly used nursing methods for patients with fecal incontinence in the prior art cannot effectively protect the perianal skin, cannot accurately observe and record the properties and quantity of stool, etc., and increase the nursing workload, and is suitable for promotion and use.
