Problems solved by technology

[0003] However, if the needle is not protected after blood collection or infusion, there will still be a risk of stabbing medical staff
At present, it is widely used in hospitals and other medical institutions to cover the needle with a protective cover to protect the needle or prevent the needle from stabbing the medical staff. It is also noticed that some blood collection needles have adopted the technical means of needle retraction. There is only one trigger switch, which is very easy to retract the needle due to misoperation during the blood collection process, causing inconvenience and loss to patients and medical staff

Embodiment Construction

[0023] The present application will be further described below by means of examples, but the present application is not limited to the scope of the examples.

[0024] figure 1 A schematic diagram of the cross-sectional structure of the safety puncture needle of the present embodiment, figure 2 For the separation of the parts of the safety puncture needle, by Figures 1 to 2 As shown, the safety puncture needle of the present application includes three parts: a casing 1, a needle body 2 and a back cover 3, wherein the needle body 2 is located inside the casing 1, one end of the needle body 2 is a needle head 21, and the other end is a needle head 21. One end is connected to a hose 23, and the needle 21 is used for puncturing a blood vessel to perform operations such as blood collection or intravenous infusion. The hose 23 can be connected to a blood collection collector or an infusion bottle.

Abstract

The invention relates to a safety puncture needle, which is mainly applied to the field of vessel puncture of puncture blood collection, transfusion and the like. The safety puncture needle comprises three parts, namely a housing, a needle body and a rear cover, wherein a syringe needle is arranged at one end of the needle body and the other end is connected with a hose; and the rear cover is connected with the housing through a thread / buckle. The safety puncture needle provided by the invention can automatically retract; the risk that the medical staff is punctured by the needle is avoided; meanwhile, by the double-side trigger device design, retraction of the syringe needle caused by misoperation can be avoided; and meanwhile, the problem of industrialized mass production is solved by a sectional structure.

Description

technical field [0001] The present application relates to the field of vascular puncture, in particular to a safety puncture needle. Background technique [0002] In medical institutions, syringes, blood collection needles, etc. are indispensable tools when collecting blood samples and transfusions for patients. At present, for the sake of medical safety, blood collection needles and syringes are all one-time use, avoiding repeated use. of cross-infection. [0003] However, if the needle is not protected after blood collection or infusion, there is still a risk of puncturing the medical staff. At present, it is widely used in hospitals and other medical institutions to cover the needle with a protective cover to protect the needle or prevent the needle from stabbing the medical staff. There is only one trigger switch, and it is very easy to retract the needle due to misoperation during blood collection, causing inconvenience and loss to patients and medical staff. SUMMAR...
