Description

Technical Field

[0001] The present invention relates to a fecal drainage device with an auxiliary insertion structure and its usage method, belonging to the technical field of medical care instruments. Background Art

[0002] In the field of clinical nursing, fecal drainage devices are the core instruments for managing the excreta of incontinent patients (including postoperative bedridden patients, intensive care patients, and patients with neurogenic bowel dysfunction). By establishing an internal rectal drainage channel, it can effectively reduce the risk of pressure injuries caused by fecal contamination (with an incidence rate of about 12 - 18%) and the probability of retrograde infection (reported in the literature to be reduced by more than 37%), which is of great significance for maintaining the dignity of patients and improving nursing efficiency.

[0003] Traditional fecal drainage devices mostly adopt a single - chamber silicone catheter structure. Medical staff need to push the catheter through the anus to the rectosigmoid junction (usually at a depth of 10 - 15 cm) based on experience. Since the flexible catheter lacking radial support is prone to tube body folding when passing through the high - pressure area of the anal sphincter (resting pressure 40 - 70 mmHg), it leads to an increase in the number of repeated catheter insertions (an average of 2.8 times per single nursing), with great difficulty in insertion and causing great discomfort to patients, which is a major problem in current clinical defecation care. Summary of the Invention

[0004] The present invention provides a fecal drainage device with an auxiliary insertion structure and its usage method to solve problems such as the great difficulty in inserting existing fecal drainage devices and causing great discomfort to patients.

[0005] To solve the above problems, a fecal drainage device with an auxiliary insertion structure is proposed, which includes a drainage catheter and a push - plate assembly inserted separately. The front end of the drainage catheter is provided with an annular airbag that can be inflated and deflated, and the end is configured with a standardized interface for connecting an extension catheter and a collection container;

[0006] The push - plate assembly is an annular structure composed of at least two semi - circular guiding pieces. The inner cavity diameter thereof matches the outer diameter of the drainage catheter, and the front end of the guiding piece is designed with an arc - shaped transition surface.

[0007] In the aforementioned fecal drainage device, the drainage catheter is made of a biocompatible material.

[0008] In the aforementioned fecal drainage device, an anti - reflux valve is provided at a position 15 - 20 cm away from the airbag inside the drainage catheter.

[0009] In the aforementioned fecal drainage device, the push - plate assembly is formed by hinging two semi - circular guiding pieces, and the front end of the guiding piece is designed with a 45° bevel transition surface.

[0010] In the above-mentioned feces drainage device, the annular inner diameter of the push plate assembly is less than or equal to the outer diameter of the drainage catheter, so that the diameter of the drainage catheter is smaller when it is inserted into the anus.

[0011] In the aforementioned feces drainage device, the thickness of the push plate assembly is less than or equal to 2 mm.

[0012] In the above-mentioned feces drainage device, there are four guide plates distributed along the circumference of the drainage catheter, and the four guide plates are respectively used to extend into four circumferentially distributed gaps separated by the connection between the annular airbag and the drainage catheter.

[0013] In the above-mentioned feces drainage device, one end of the drainage catheter is connected to the annular airbag, and the other end is connected to the extension catheter and the collection container, and the length of the drainage catheter is greater than 20 cm and less than 50 cm.

[0014] The present invention also provides a method for using the feces drainage device with an auxiliary insertion structure, which is specifically as follows:

[0015] During clinical operation, the assembled push plate assembly is first sleeved on the drainage catheter proximal to the annular airbag, and after lubrication, the entire assembly is inserted into the rectum to a predetermined depth. After the annular airbag is inflated and fixed, the push plate assembly is taken out and the push plate assembly is disassembled.

[0016] In the above method, when using, firstly, the gas in the annular airbag is exhausted to reduce the volume of the airbag;

[0017] Then, the push plate assembly is assembled and sleeved on the drainage catheter, and the push plate assembly is pushed toward the direction where the annular airbag is located so that one end of the push plate assembly extends between the annular airbag and the drainage catheter;

[0018] Then, the annular airbag and the front end of the drainage catheter are pushed into the designated position in the anus by the push plate assembly;

[0019] The annular airbag is inflated through an inflation tube matched with the annular airbag, so that the annular airbag is stuck in the anus, and then the annular airbag is withdrawn separately and the push plate assembly is removed to complete the insertion of the feces drainage device.

[0020] Compared with the prior art, the present invention replaces the traditional manual push-and-insert method with a designed insertion device, which significantly reduces the diameter of the object to be delivered at the anus, improves the convenience of insertion and reduces the pain of the patient. The insertion and removal of the device are very convenient. The innovative structure also reduces the resistance to catheter insertion through temporary channel support, and cooperates with the airbag non-compression fixation technology to effectively avoid mucosal irritation and perianal skin damage caused by traditional catheterization. It is particularly suitable for the medium- and long-term feces management of incontinent patients, improves the operation and hygiene level of medical staff, and is suitable for promotion and application.
