Functional fixer (paster/sheet/membrane) of indwelling needle/indwelling tube

Abstract

A functional fixer (paster / sheet / membrane) of an indwelling needle / indwelling tube comprises an edge-reserved film 1, a functional water absorption pad 3, a fixing pasting film and a supporting layer 5. The fixing pasting film is made of degradable biology base materials; medical silica gel capable of realizing repeated pasting is used as pasting materials of an adhesive strip; the pasting materials are arrayed in a strip mode or in a dot matrix mode so that the contact area between the pasting materials and the skin can be decreased and breathability can be improved on the premise that pasting strength is guaranteed. The portion, making contact with the skin, of the functional water absorption pad is provided with an anti-adhesion film; a middle layer is a water absorption layer; the water absorption layer is coated with a functional layer which is made of photobiotin composite medical materials or far infrared materials. The radiation effect of the functional layer is utilized to act on the molecular structure of liquid medicine and blood so that molecular groups of the liquid medicine and blood can become small. Through the radiation effect on organism issue on the periphery of an opening punctured by the needle, blood circulation is improved, and pain is alleviated.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to a functional fixer (sticker / sheet / membrane) for indwelling needle / indwelling tube for protecting infusion needle ports and puncture ports. Background technique [0002] The main function of the infusion needle protection film is to block the needle port and prevent pollution; the second is to absorb the blood, medicine liquid and sweat from the human body from the needle port, and usually add Chinese and Western medicine ingredients to play an anti-inflammatory effect. Pain relief is achieved through the local anesthetic action of the drug. [0003] During infusion, usually the temperature of the liquid in the bottle is lower than the body temperature of the human body. Especially in winter, the temperature of the liquid in the hanging bottle is often lower than the normal temperature of the human body. After the low-temperature medicinal liquid enters the h...

Problems solved by technology

To solve this problem, the most conventional and effective way is to heat and keep the medicine bottle warm, but this often increases the labor intensity of medical staff and is cumbersome, so it is difficult to popularize and apply in reality

[0004] In addition, the existing infusion needle film, the coating of medical glue usually adopts the method of full-width coating, which has the advantage of being able to be effectively fixed, but the disadvantage is that it is not easy to disassemble and has poor air permeability. cause allergies

[0005] In patent No. 201120194316.0, a kind of venous indwelling needle fixing device is disclosed. Its advantage is that it can fix the venous indwelling needle well. The disadvantage is that the fixed venous indwelling needle is stuck on the double-sided compress. Tear off the double-sided compress sticking to the skin, it is easy to pull the needle tube and cause pain

[0006] In the patent No. 200620161724.5, a fixed application of intravenous indwelling needles is disclosed, which is used for head vein injection. The problem is that the indwelling needles should be fixed on the skin with adhesive tape, and the needle port will still be pulled when the adhesive tape is torn off.
