Disposable hemostix

Abstract

The invention discloses a disposable hemostix. The disposable hemostix comprises a housing, wherein a clamping piece is fixed in the housing and is used for clamping a blood taking needle; a pressure spring is arranged between the clamping piece and the blood taking needle; a push device is arranged on the front side of the clamping piece, and can act on the clamping piece to open a clamping opening in the clamping piece; a part of the push device is exposed outside the housing; an ejection cavity and a needle outlet hole communicated with the ejection cavity are arranged in the push device; the ejection cavity can allow the blood taking needle to be ejected out from the ejection cavity; the core of the blood taking needle is sleeved with a needle core sleeve; the needle core sleeve is fixedly connected with a needle bed through a material easy to twist off. Through the adoption of the disposable hemostix, the common conditions that a blood taking needle is stuck and the ejection of the blood taking needle is blocked when a key is fitted with a groove are avoided; meanwhile the problem that in the prior art, a blood taking needle is not well protected, so that sampled blood is susceptible to contamination and the core of the blood taking needle cannot be used only after being cleaned and disinfected is solved.

Description

technical field [0001] The invention relates to the field of medical blood collection instruments, in particular to a disposable blood collection device. Background technique [0002] A blood sample collection procedure is often required for blood testing; at present, a syringe blood collection needle or a disposable blood collection needle is often used for blood sampling. Disposable blood collection needles have great advantages in preventing mutual infection of patients or groups of people, and are convenient to use. Currently, they are more common in clinical use, especially for blood sampling of special groups of people such as children. When using the automatic blood collection needle, you only need to put the blood collection needle close to the user's skin to collect blood, and it can be operated with one hand. Compared with the syringe blood collection method, the blood collection time by using the automatic blood collection needle is shortened by 1.5 minutes on av...

Problems solved by technology

[0010] The object of the present invention is: to solve the above problems, provide a disposable blood collection device to solve the problem that the blood collection needle cannot collect blood or the effect of blood collection is not good due to the unreasonable setting of the guiding mechanism of the blood collection device in the prior art, and also solve the problem of blood collection in the prior art. Inadequate protection of the needle leads to easy contamination of the blood collection needle, and the needle core of the blood collection needle needs to be cleaned, disinfected and aseptically treated before it can be used. At the same time, it also solves the technical problem that the penetration depth of the blood collection needle cannot be adjusted in the prior art
