Venous indwelling needle film

Abstract

The invention discloses a venous indwelling needle film. The film comprises a main film, a longitudinal shaping part is arranged on the main film in a protruding manner; a c-shaped adhesive paper is arranged on one side, deviating from the longitudinal shaping part, of the main film; a contact surface of the C-shaped adhesive paper and the main film is a C-shaped adhesive surface; a first strip-shaped adhesive paper is arranged on the inner folding surface of the longitudinal shaping part; the contact surface of the first strip-shaped adhesive paper and the longitudinal shaping part is the first strip-shaped adhesive surface; a heparin cap fixing film is arranged on one side of the main film; the heparin cap fixing film comprises a joint part and a vacant part; the joint part and the heparin cap fixing film are fixed through bonding; and a V-shaped cavity is formed by the vacant part and the heparin cap fixing film, a second strip-shaped adhesive paper is correspondingly arranged on one side of the vacant part, and the contact surface of the second strip-shaped adhesive paper and the vacant part is a second strip-shaped adhesive surface, so that the film has the characteristics ofconvenience in fixing the needle head and comfort in 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
