Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to an intestinal stent-type irrigation device that can be flushed and aspirated. Background Technology

[0002] In recent years, with the improvement of people's living standards, the incidence of gastrointestinal diseases has been increasing, and the demand for gastrointestinal surgery has also increased. As the third space in the human body, the stomach and small intestine require preoperative irrigation in gastrointestinal surgeries.

[0003] Preoperative bowel irrigation currently involves inserting a tube through the gastrostomy or anus to pump water into the body from outside, allowing the water to mix thoroughly with the intestinal contents before draining. However, this method often results in the tube not fitting properly to the stoma or anus, making it easy for the pumped water to splash out and fill the patient's clothes and the irrigation area with the mixture of water and intestinal contents. This can cause psychological discomfort for the patient and reduce patient compliance.

[0004] Therefore, how to provide a flushable and aspirable intestinal stent irrigation device to solve the problem of water and intestinal contents splashing out from the stoma or anus is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides an intestinal stent-type irrigation device that can be flushed and aspirated, aiming to solve one of the problems in the above-mentioned background art, and to solve the problem of water and intestinal contents splashing out from the stoma or anus.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A flushing and aspiration intestinal stent-type irrigator, comprising: A water pipe is provided with an inlet and outlet tee assembly, the three channels of which are respectively configured as an inlet, an outlet, and an air inlet; An external bonding and fixing component is disposed at one end of the water pipe away from the inlet / outlet tee assembly; A leak-proof negative pressure component is installed on the water pipe and is configured as a semi-circular, semi-closed cavity that is connected to the external bonding and fixing component. A side-opening suction pipe is connected to the inlet of the inlet / outlet tee assembly, and a number of elliptical holes are provided on the side wall of the side-opening suction pipe. An internally inflatable fixing airbag is provided on the side-opening suction tube. The internally inflatable fixing airbag is connected to the air inlet. One end of the internally inflatable fixing airbag is a sealed cavity whose volume can change as air is inflated.

[0007] Furthermore, the other end of the internally inflatable fixing airbag is provided with a one-way air intake valve.

[0008] Furthermore, the external adhesive fixing component is configured as a cuttable medical adhesive tape, and the external adhesive fixing component is provided with scale lines.

[0009] Furthermore, the elliptical holes on the sidewall of the side-opening suction tube are arranged in a spiral.

[0010] Furthermore, the internally inflatable fixing airbag is configured as a long, spherical airbag.

[0011] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an intestinal stent-type irrigation device that can be flushed and aspirated, with the following beneficial effects: This device is suitable for patients with gastrointestinal stomas and is used for rinsing the gastrointestinal stoma. After being pre-cut to the size that can just accommodate the stoma, the side-opening suction tube can be inserted into the appropriate position from the gastrointestinal stoma. Appropriate gas is pumped in through the air inlet to increase the volume of the balloon, which can just hold the gastrointestinal tract in place, forming the first layer of fixation. Gently squeeze the leak-proof negative pressure component to adhere it to the stoma, forming a second layer of fixation; cover the skin around the stoma with the pre-cut external fixation component to form a third layer of fixation, thereby ensuring that the device can be firmly attached to the stoma, allowing water to enter the intestine through the flushing tube and mix thoroughly with the gastrointestinal contents before being suctioned out through the flushing tube under negative pressure, greatly reducing the splashing of the water-gastrointestinal contents mixture; It can also be used for intraoperative gastrointestinal lavage. If gastrointestinal lavage is required during surgery, this device can greatly reduce the contamination of gastrointestinal contents with aseptic surgery, reduce the risk of intraoperative infection for patients, and reduce some unnecessary work for medical staff. It can also be used to irrigate the obstructed upper part of the intestine in patients with incomplete intestinal obstruction caused by tumors in the colorectal region, making irrigation more convenient; It can also be used for daily anal care for middle-aged and elderly people. For middle-aged and elderly people, fecal accumulation and changes in flora in the anus and rectum can easily lead to perianal abscess and anal fistula. This device allows people to perform daily perianal care at home and reduce the occurrence of perianal abscess and anal fistula. The external fitting and fixing components can be cut to a suitable size according to the size of the stoma and anus, so as to better fit the stoma or perianal skin. Attached Figure Description
