Abstract

The invention provides a hemostix. The hemostix comprises a catheter seat, a blood sampling structure and a connecting pipe, wherein an accommodating cavity is formed inside the catheter seat; a catheter for accommodating a puncture needle tube is fixedly arranged at one end of the accommodating cavity; the hardness of the catheter is less than that of the puncture needle tube; the puncture needletube has a first state in which the puncture end extends out of a catheter, and a second state in which the puncture end is retracted toward the catheter seat and is separated from the catheter seat;the blood sampling structure comprises a blood collection needle; the connecting pipe is connected with the catheter seat and the blood sampling structure, and is communicated with the accommodatingcavity and the blood collection needle; and the hardness of the connecting pipe is not less than that of the catheter seat. According to the hemostix, pains of a person waiting for blood sampling canbe relieved in the blood sampling process, blood sampling operation can be performed conveniently, and accuracy of a blood detection result can be improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blood sampling device. Background technique [0002] A traditional blood collection device usually includes a blood collection needle holder and a blood collection needle connected with the blood collection needle holder, and the blood collection needle is generally a steel needle. During the blood collection process, sometimes due to the non-cooperation of the person to be collected or multi-tube blood collection, repeated insertion and removal of the vacuum blood collection tube will cause the position of the steel needle to move in the blood vessel of the person to be collected, resulting in the steel needle piercing the blood vessel and interrupting the blood collection . [0003] There is a blood collection device, which comprises a needle tube retractable venous indwelling needle, the needle tube retractable venous indwelling needle has a needle handle, a ven...
