Problems solved by technology

However, there are certain deficiencies in clinical operation: its structure must make the product formed by its technology: the infusion needle sheath is located at one end of the infusion needle hose (near the infusion filter side) when it leaves the factory, and the surface of the infusion needle body still needs a Only the protective cover has caused waste to the production unit; in addition, its safety device is a circular tube without a hand-held structure. Entering the safety protection tube, and this alignment work is very troublesome. The nurse needs to rotate the protection tube to align the V-shaped notch at the tip of the infusion needle handle to achieve
Therefore, its structural defects cause difficulties in clinical use and are not conducive to the promotion and use of its products.

Embodiment Construction

[0016] Such as figure 1 As shown, the present invention has both a disposable transfusion venipuncture needle protective sleeve, including a protective sleeve 1 and a handle 2; The outer surface of the needle handle 5 forms a protection for the venipuncture needle. The front and rear ports 1a and 1b of the protective sleeve are in communication, and the length of the sleeve is greater than the total length of the venipuncture (infusion) needle 3 connected to the needle holder handle;

[0017] Such as figure 2 As shown, a 1.8×8.0 mm rectangular slot 1c is opened on the side wall of the proximal end of the cannula 1, in which the wing root of the handle of the puncture (infusion) needle can be limited; The angle is obliquely reduced to 0.5mm wide and extended 5.0mm to form a narrow slit 1d, and then expanded obliquely at 45° to 1.8mm to form a wide slit 1e that extends to the distal end of the cannula and slits at the distal end of the cannula The bottom has a semicircular o...

Abstract

A protective sleeve tube for the expendable venipuncture needle is compose dof a sleeve tube body and a handle arranged longitudinally on said sleeve tube body. It can conveniently recover the used puncture needle in it, so preventing its damage to person.

Description

technical field [0001] The invention relates to a puncture needle protection device, in particular to a venipuncture needle protection sleeve used for medical purposes. Background technique [0002] Disposable venipuncture needle is an indispensable medical device in the process of intravenous infusion, blood collection and treatment. At present, most of the protective measures for venipuncture needles used in clinical practice are to put a soft plastic sleeve on the tip of the venipuncture needle and the surface of the needle body to prevent the needle body from being polluted; Only when the tube is removed can the venipuncture operation be carried out. After the infusion is completed, the hose sheath is also missing, which cannot prevent the needle body or needle point from hurting nurses and other contact personnel again. [0003] There are also units or individuals in China who have conducted research on this issue, such as: ZL: 02112068.4, describing "a single-wing inf...
