A kind of intravenous indwelling needle patch

Abstract

The invention discloses a film for venous indwelling needles, which comprises a main film, on which a longitudinal shaping part protrudes, and a C-shaped adhesive sheet is provided on the side of the main film facing away from the longitudinal shaping part. The contact surface between the C-shaped adhesive sheet and the main film is a C-shaped adhesive surface, and the inner folding surface of the longitudinal shaping part is provided with a first strip-shaped adhesive sheet, and the first strip-shaped adhesive sheet is connected to the longitudinal The contact surface of the shaping part is the first sticking surface, and one side of the main film is provided with a heparin cap fixing film, and the heparin cap fixing film includes a joint part and a hollow part, and the joint part and the heparin cap The fixing film is fixed by bonding, the hollow part and the heparin cap fixing film form a V-shaped cavity, and one side of the hollow part is correspondingly provided with a second strip-shaped adhesive sheet, and the second strip-shaped adhesive sheet The contact surface with the hollow part is the second strip-shaped adhesive surface. The present invention has the characteristics of convenient needle fixing and comfortable wearing.

Description

technical field [0001] The invention relates to the technical field of venous treatment and nursing, in particular to a film for venous indwelling needles. Background technique [0002] Indwelling needles have been widely used clinically, and their effective application has relieved the pain of repeated punctures for patients with long-term infusions. The indwelling needles are generally fixed by a transparent applicator, and do not need to be pulled out from the human body after the first infusion. Anticoagulants can be used repeatedly within a few days. [0003] In clinical work, it is found that the improper fixation of the indwelling needle has brought about many nursing problems: [0004] (1) The curling of the indwelling needle film, the long-term placement of the indwelling needle handle can easily lead to local skin pressure injury, the shedding of the indwelling needle film will cause the indwelling needle to slip off, and the tight sticking of the indwelling needl...

AI Technical Summary

Problems solved by technology

[0004] (1) The curling of the indwelling needle film, the long-term placement of the indwelling needle handle can easily lead to local skin pressure injury, the shedding of the indwelling needle film will cause the indwelling needle to slip off, and the tight sticking of the indwelling needle will easily lead to discounts at the needle stem of the indwelling needle Problems such as poor infusion, discounted end of indwelling needle or need for repeated fixation will affect the smooth progress of infusion, increase the pain of patients, and require repeated operation and communication and explanation by nurses;

[0005] (2) Although there are ventilation holes on the existing indwelling needle application, the skin is always attached to the application, without air circulation, which is inconvenient for ventilation and perspiration, resulting in poor application bonding effect;

[0006] (3) The existing indwelling needle needs to be pasted with a transparent film to fix the end of the infusion tube and heparin cap in a U shape. This process is cumbersome to operate, and too much adhesive tape will easily cause discomfort on the patient's skin;

[0007] (4) In addition, the indwelling needle is not easy to fix during the indwelling process. Due to the pulling effect of the anticoagulant injection head and the hose, the infusion needle is easy to deviate from the human blood vessel, which cannot meet the conditions for reuse
