Nasobiliary catheter fixing plaster

Abstract

The invention provides a nasobiliary catheter fixing plaster. The nasobiliary catheter fixing plaster comprises a nose plaster and a cheek plaster, wherein the nose plaster and the cheek plaster consists of an adhesion layer, a debonding layer, a dressing layer, a flexible plastic layer and an omega-shaped fixing groove. The nasobiliary catheter fixing plaster is characterized in that the nose plaster is in the shape of a strip; the omega-shaped fixing groove of the nose plaster is J-shaped, and a stickiness foam strip is arranged in the omega-shaped fixing groove; the cheek plaster is circular, and the omega-shaped fixing groove of the cheek plaster is crossed, and is divided into an upper layer and a lower layer, and the middle part is hollow. The nasobiliary catheter fixing plaster disclosed by the invention has the advantages of being ingenious and artistic in design, high in adhesivity, good in air permeability, light in weight, easy to replace, good in comfort degree, high in practicality, low in cost expense and the like.

Description

technical field [0001] The invention relates to a nasobiliary duct fixing plaster. Background technique [0002] Endoscopic nasobiliary drainage is a routine clinical endoscopic technique, which can be directly applied to the treatment of obstructive jaundice, acute suppurative cholangitis, bile leakage and other diseases. Postoperative indwelling nasobiliary duct can fully drain bile, reduce biliary pressure, and reduce the probability of postoperative pancreatitis and cholangitis; at the same time, it can observe the properties and outflow of bile, and can be used for acute suppurative cholangitis and delayed biliary hemorrhage. Sensitive antibiotics or hemostatic drugs are injected through the nasobiliary drainage tube, and the clinical effect is remarkable. [0003] Effective fixation of the nasobiliary duct is the most effective way to prevent the displacement of the nasobiliary duct. At present, adhesive plasters are often used to fix the nasobiliary duct. The specifi...

AI Technical Summary

Problems solved by technology

[0008] The above-mentioned fixing method has the following disadvantages: 1. Due to the large amount of sweat in the nose and cheeks, the traditional adhesive tape is used for fixing, and the adhesive tape is easy to loosen, while using a large piece of adhesive tape to fix it affects the appearance, and long-term fit can cause skin allergies; 2. At present The tails of the nasobiliary ducts used are all straight. When the nasobiliary ducts are fixed, corners are formed at the nose and cheeks. Due to the tension of the nasobiliary ducts themselves, it is an important reason why the adhesive tapes on the nose wings and cheeks are difficult to fix for a long time;4 .The nasobiliary duct is fixed with a fixed buckle, which can avoid the influence of the tension of the nasobiliary duct at the cheek at the corner, but the nasobiliary duct at the alar of the nose will still squeeze the alar of the nose once, causing discomfort to the patient, long-term compression and even local redness, swelling and ulcers
