Composite thin film for medical wrist strap and preparation technology of composite thin film

Abstract

The invention discloses a composite thin film for a medical wrist strap. The composite thin film is characterized by comprising a protection layer, a composite adhesive layer and an identification layer in sequence, wherein the protection layer refers to an EVA (Ethylene-Vinyl Acetate) thin film, the composite adhesive in the composite adhesive layer refers to polyether composite adhesive, and the identification layer refers to thermosensitive paper with a layer of thermosensitive coating with thickness of 1-5 micrometers. The protection layer in the composite thin film is soft in texture and does not scratch any patient; the composite adhesive in the adhesive protection layer and the identification layer of the composite thin film is high in adhesion strength, the phenomena of cracking, curling and the like do not occur, and the preparation technology is simple in process, low in requirements for technological conditions, low in investment cost and suitable to large-scale production.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a composite film for a medical wristband and a preparation process thereof. Background technique [0002] In the hospital, each doctor or nurse has to face a large number of patients every day, and it is difficult to remember the specific information of each patient, which will lead to the inability to treat or save the patients in time. At present, most of the information of each patient in the hospital, especially the information of inpatients, is recorded on a card, and then the card is directly placed at one end of the patient's bed. This way of using the card is easy to be lost or even replaced. For this reason, some hospitals have wristbands worn on the patient's wrist, but these wristbands are prone to curling and deformation when worn, and cannot quickly read patient information, and the existing wristbands are locked on the wrist by a pull buckle , the wrist is prone to ...

Problems solved by technology

[0002] In the hospital, each doctor or nurse has to face a large number of patients every day, and it is difficult to remember the specific information of each patient, which will lead to the inability to treat or save the patients in time

At present, most of the information of each patient in the hospital, especially the information of inpatients, is recorded on a card, and then the card is directly placed at one end of the patient's bed. This way of using the card is easy to be lost or even replaced. For this reason, some hospitals have wristbands worn on patients’ wrists, but these wristbands are prone to curling and deformation when worn, and cannot quickly read patient information, and the existing wristbands are locked on the wrist by a pull buckle , the wrist is prone to injury

At the same time, the information in the wristband is easy to be worn, making it difficult to see clearly. For this reason, the composite film used in medical wristbands is very important. If the composite film is too hard, it will cut patients, especially newborn babies, and the composite film is required to be soft. , so there must be a layer of soft protective layer on the composite film, and there must be an identification layer for printed text on the composite film. Long, often the composite film will curl when the composite glue in the composite film is dry or the adhesion is insufficient
