Lancet device with detachable lancet

Abstract

The present invention provides a lancet device with a separable lancet, comprising a pen body and a needle holder, the pen body comprising a first pen body, a second pen body and a connecting part, and the needle holder is arranged on the first pen body and the needle holder. Between the second pen bodies, a first guide channel is arranged in the second pen body along the axial direction, and a second channel is arranged in the needle seat, the needle seat has a first state and a second state, and the first pen body A striker assembly is provided, the striker assembly including a striker rod coaxial with the first guide channel, the striker rod being configured to be capable of knocking the needle inside the needle hub when the needle hub is in the first state. The blood collection needle is bumped into the first guide channel, and the blood collection needle is slid in the first guide channel to form a puncture action. This setting method can avoid the process of repeatedly disassembling and assembling the pen cap, and remove and install the blood collection needle until the When the needle seat is used, the medical staff does not need to touch the needle head of the blood collection needle, which can effectively avoid the phenomenon of cross-contamination and hand stab wounds.

Description

technical field [0001] The present invention generally relates to the technical field of medical devices, in particular to a lancet device with a separable lancet. Background technique [0002] The lancet used for peripheral blood collection is a commonly used medical device. The lancet is a blood collection device used in conjunction with a disposable lancet. The lancet can be reused, and the lancet is only for one-time use in order to avoid cross-infection. . The development of lancing pens has a history of decades, and the improvement of lancing pens has also gone through many stages. At present, lancing pens are gradually becoming mature. [0003] In the prior art, in order to realize the replaceability of the lancet, a needle seat is generally provided in the lancet, and a threaded cap is provided at the end of the lancet. The needle seat can be exposed by removing the cap, and then the The lancet is plugged into the needle holder, and then the cap is installed on the...

Problems solved by technology

[0003] In the prior art, in order to realize the replaceability of the blood collection needle, a needle seat is generally provided in the blood collection pen, and a screw cap is provided at the end of the blood collection pen, and the needle seat can be exposed by removing the cap, and then the The blood collection pen is plugged into the needle seat and then the cap is installed on the blood collection pen. After the puncture work is completed, the pen cap is removed again, and then the blood collection needle is replaced. The cap needs to be installed and disassembled every time, which is troublesome to use, and the hands of the medical staff will touch the needle part of the blood collection needle when removing the used blood collection needle, which may cause cross contamination when the medical staff takes a new blood collection needle again , and the needle may cause injury to the medical staff when the medical staff takes off the blood collection needle, so it is necessary to improve the blood collection pen
