Blood taking needle and blood taking device formed by same

Abstract

The invention discloses a blood taking needle and a blood taking device formed by the blood taking needle, and belongs to the field of medical equipment, the blood taking needle comprises a needle head and a protective sleeve which are of an integrated structure, the protective sleeve covers the outer side of the needle head, the needle head penetrates through the protective sleeve downwards in the axial direction, and a sleeve head is arranged at the lower end of the needle head and is made of a soft material; the protective sleeve comprises a driving section located at the upper end and a fixing section located at the lower end, the needle head is wrapped with the fixing section, the driving section is arranged at the upper end of one side of the fixing section, and the driving section comprises a hanging lug protrusion located on the inner side of the upper end, a third positioning protrusion located on the middle outer ring and a thin-wall area located on the inner side of the lower end. According to the blood taking needle, the multiple needle heads can be used at the same time, the occupied space is small, the structure is compact, the number of wrapping layers outside the blood taking needle is small, cost is saved, operation is convenient, the medical waste treatment cost is reduced, the part making contact with the human body is always in a protection state, and external infection is prevented.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a blood collection pen, in particular to a blood collection device composed of a plurality of blood collection needles. Background technique [0002] The lancet is used for blood sampling, routine physical examination, blood sugar check, etc., which requires a lancing pen. The lancet is a kind of lancet. The structure uses a mechanical device, and the needle adopts an ejection device, which can be almost completely accurate and fast. , Moderate depth, straight line piercing the skin, greatly reducing the pain of the patient, making sampling enter a new stage of development, basically solving the problems of strong pain and large wounds of the previous two generations of blood collection needles. [0003] At present, the commonly used lancets on the market are mostly plastic-coated and disposable. When using, the end needs to be removed and then placed on the lancet for use, which i...

Problems solved by technology

[0003] At present, the blood collection needles commonly used in the market are mostly plastic-coated and disposable. When using, the end needs to be removed, and then placed on the blood collection pen for use. The operation is cumbersome and time-consuming.

Each small needle needs to be equipped with an external fixing sleeve, and it is a disposable product, which consumes a lot of money. In addition to the increase in cost, it also brings certain difficulties to the subsequent medical waste disposal, and this structure takes up a lot of space, which is difficult To realize the structure of the multi-head blood collection pen, the common multi-head structure in the market is that multiple heads act at th
