Description

Needle for vacuum blood collection tube

technical field

The utility model relates to the field of medical supplies, in particular to a matching needle for vacuum blood collection tubes.

Background technique

In clinical treatment and outpatient inspection, it is necessary to collect a large number of venous blood samples for various inspections every day. Compared with the traditional syringe blood collection method, vacuum blood collection technology is generally used in outpatient clinics. The invention of vacuum blood collection technology is the establishment On the basis of the traditional blood collection method, it cleverly redesigns and combines needles, syringes and test tubes to form a fully enclosed vacuum blood collection system, which is mainly composed of two parts: a venipuncture needle, a bottle stopper puncture needle and a hose Composed of a bidirectional sterile needle, one end is punctured into the vein through the skin, and the other end is connected to a vacuum tube. Because hospitals are generally relatively busy at present, medical staff are easy to stab themselves when connecting the cork puncture needle to the vacuum test tube, so it is necessary to improve the matching needle for the current vacuum blood collection tube.

Contents of the invention

In order to solve the above problems, the purpose of this utility model is to provide a needle used for vacuum blood collection tubes, which uses a needle seat to surround the bottle stopper puncture needle, so as to prevent medical staff from accidentally stabbing themselves and improve Use security.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

A needle used for vacuum blood collection tubes, comprising a flexible tube, a venipuncture needle set and a bottle stopper puncture needle set arranged on both ends of the flexible tube; the venipuncture needle set includes a needle handle, and venipuncture needle; the bottle stopper puncture needle set includes a needle seat matched with the vacuum blood collection tube cover, and a bottle stopper puncture needle arranged on the needle seat; the needle seat side wall of the needle seat surrounds a needle Seat groove, the cork puncture needle is in the center of the needle seat groove, and the needle tip of the cork puncture needle is lower than the side wall of the needle seat; A side wall of the needle point is formed, and a needle point groove communicating with the needle point is opened on the side wall of the needle point.

The utility model adopts the above-mentioned technical scheme. The bottle stopper puncture needle group of the vacuum blood collection tube matching needle includes a needle seat and a bottle stopper puncture needle arranged in the needle seat. The needle tip of the bottle stopper puncture needle is lower than the needle seat. Side wall; when in use, medical staff need to match the needle seat with the cap of the vacuum blood collection tube to buckle, so that the cap can be pierced through the cork puncture needle, so as to avoid the accident of medical staff accidentally stabbing themselves, and improve Safe to use. In addition, the cork puncture needle is provided with a needle point groove, so that the needle tube forms a non-closed surrounding needle point side at the needle point; when the needle point pierces the rubber bottle cap, the needle point slope will not completely fit the rubber cap. Therefore, when piercing, the side of the needle point will puncture and cut off the corresponding rubber bottle cap, but the rubber bottle cap corresponding to the needle point groove will not be cut off; when the needle continues to extend downward, the bottom of the needle point groove will When touching the corresponding rubber, since the front end rubber has been cut off, there is no point of force on the rubber, and the rubber will only be turned over and pressed down without being cut off; therefore, the needle with this structure will not cut off the rubber particles, thereby avoiding cutting The impact of rubber particles on blood draw results.

detailed description

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.

A needle for supporting a vacuum blood collection tube as shown in FIGS. The set includes a needle handle 21 and a venipuncture needle 22 disposed on the needle handle 21 . The bottle stopper puncture needle set includes a needle base 31 matched with the cap of the vacuum blood collection tube, and a bottle stopper puncture needle 32 arranged on the needle base 31; the needle base side wall of the needle base 31 is enclosed to form a needle base Groove, the cork piercing needle 32 is at the inner center of the needle seat groove, and the needle tip of the cork piercing needle 32 is lower than the side wall of the needle seat, that is, the needle tip of the cork piercing needle 32 does not exceed the side wall of the needle seat. The needle point of the bottle stopper puncture needle 32 is arranged in a bevel shape, and the side wall of the needle tube forms a needle point side wall 321 at the needle point, and a needle point groove 322 communicating with the needle point is opened on the needle point side wall.

In summary, the cork puncture needle 32 group of the vacuum blood collection tube matching needle includes the needle base 31 and the bottle stopper puncture needle 32 arranged in the needle base 31, the needle tip of the bottle stopper puncture needle 32 is lower than The side wall of the needle holder; when in use, the medical personnel need to match the needle holder 31 with the cap of the vacuum blood collection tube to buckle, so that the cap can be pierced through the bottle stopper puncture needle 32, thereby preventing the medical personnel from accidentally stabbing their own blood vessels. Accidents occur, and the safety of use is improved. In addition, the cork puncture needle 32 is provided with a needle point groove, so that the needle tube forms a non-closed needle point side wall at the needle point; when the needle point pierces the rubber bottle cap, the needle point slope will not completely fit Therefore, when piercing, the side of the needle point will puncture and cut off the corresponding rubber bottle cap, but the rubber bottle cap corresponding to the needle point groove will not be cut off; when the needle continues to extend downward, the needle point groove will When the bottom is against the corresponding rubber, since the front rubber has been cut off, there is no point of force on the rubber, and the rubber will only be turned over and pressed down without being cut off; therefore, the needle with this structure will not cut off the rubber particles, thereby avoiding The effect of excised rubber microparticles on blood draw results.
