Safe blood-taking-needle holder

Abstract

The invention relates to a safe blood-taking-needle holder. The safe blood-taking-needle holder comprises an outer sleeve and an inner sleeve, wherein the center of the opening of the front end of the outer sleeve is connected with a blood-taking-needle connecting base through a connecting rib plate, a sliding groove is axially formed in the wall of the outer sleeve, and the rear end of the sliding groove is provided with an opening; the inner sleeve is arranged in the outer sleeve in a sliding mode, a guide groove matched with the connecting rib plate is axially arranged on the wall of the inner sleeve, the front end of the guide groove is provided with an opening, the outer wall is provided with a sliding block, and the sliding block protrudes outwards and can slide along the sliding groove of the outer sleeve; a locating clamping groove matched with the sliding block is formed in the portion, close to the opening at the rear end, in the sliding groove, and a locking clamping groove matched with the sliding block is formed in the front portion of the sliding groove. The safe blood-taking-needle holder is reasonable in structure, convenient to mount, dismount and use, easy to operate, and capable of effectively preventing a blood taking needle from pricking medical workers and cleaners in a using process, thereby preventing cross infection caused by accidental pricking by the needle, and being good in safety.

Description

technical field [0001] The invention relates to a medical device, in particular to a safety needle holder for blood collection needles. Background technique [0002] We know that blood collection needles and blood collection tubes are essential tools in the blood collection process. In the past, traditional syringes were commonly used to draw blood, and then transferred to blood collection tubes for inspection and other operations; in recent years, one-step direct blood collection with vacuum tubes has become a more advanced blood collection method. Vacuum tube one-step direct blood collection adopts three sets of blood collection equipment including double-ended blood collection needle, needle holder and vacuum blood collection tube. The existing needle holder mainly includes a blood collection needle connection seat and a hollow blood collection tube overtube. After the double-ended blood collection needle is installed and fixed, one end is located at the front end of th...

AI Technical Summary

Problems solved by technology

After the blood collection is completed, both hands must be operated at the same time to separate the needle holder from the double-ended blood collection needle and dispose of the blood collection needle. The operation is cumbersome and complicated, and the exposed needle also has great unsafe factors

And if the needle holder and the blood collection needle are not separated, the two sets are processed at the same time, and the needle holder can only be used once like the blood collection needle, which also increases the cost of blood collection
