Problems solved by technology

In the blood collection needle with the above structure, the sliding mechanism can wrap the needle tube, effectively preventing the blood collection needle from stabbing people twice, but the structure still has the following defects: 1. The blood collection needle is pulled out from the human vein after blood collection. Finally, there may be a small amount of human blood on the needle tube, and the sliding mechanism only wraps the needle tube from the periphery of the needle tube, and the blood on the needle tube may drip out, causing pollution; 2. The sliding mechanism is not smooth enough to push and clamp

Embodiment 1

[0043] See Figure 1 to Figure 9 The blood sampling needle for preventing secondary acupuncture in this embodiment includes a needle tube base 1, a needle tube provided at the front end of the needle tube base 1, a handle base 3 connected to the back end of the needle tube base 1, and a sliding sleeve movably sleeved on the needle tube base 1. The sleeve 4 and the needle tube sheath 5 sheathed on the needle tube 2, the needle tube base 1 is connected to the blood collection tube puncture needle 7 through the blood collection catheter 6, and the sliding sleeve 4 and the needle tube base 1 are moved relative to the needle tube base 1 through a sliding mechanism. To move, the sliding mechanism includes a sliding groove 8 and a sliding block 9. The sliding block 9 is matched and embedded in the sliding groove 8, and the sliding block 9 moves in the sliding groove 8 along the track direction from the head end to the end of the sliding groove 8; The track of 8 is a smooth curve formed...

Embodiment 2

[0061] See Figure 10 to Figure 18 The structure and working principle of the lancet for preventing secondary needling in this embodiment are similar to those in the first embodiment, except for the assembly form of the sliding sleeve 4 and the handle base 3. In this embodiment, only the upper part of the sliding sleeve 4 is cylindrical, and the lower part is semi-open. The seat body 26 of the handle seat 3 is located in the open part of the lower part of the sliding sleeve 4, and the lower part of the sliding sleeve 4 and the seat body 26 together form a cylinder. Shape, realize assembly. The specific structure is as follows: the handle seat 3 includes a seat body 26 and a handle 27 provided on one side of the seat body 26. A second opening 31 is opened on the side wall of the seat body 26 and the upper end of the second opening 31 is open; the lower side wall of the sliding sleeve 4 has The third opening 30 and the lower end of the third opening 30 are open; corresponding to...

Abstract

The present invention belongs to the technical field of medical devices and discloses a blood taking needle capable of preventing secondary acupuncture. The blood taking needle capable of preventing the secondary acupuncture comprises a needle tube seat, a needle tube arranged at a front end of the needle tube seat, a handle seat connected to a rear end of the needle tube seat, a sliding sleeve movably sleeving the needle tube seat and a needle tube protective sheath sleeving the needle tube, the sliding sleeve moves relative to the needle tube seat through a sliding mechanism between the sliding sleeve and the needle tube seat, the sliding mechanism comprises a sliding groove and a sliding block, the sliding block is matched in the sliding groove, and besides the sliding block moves in the sliding groove along a track direction from a head end to a tail end of the sliding groove; the track of the sliding groove is a smooth curve formed by sequentially connecting at least two line segments, and an included angle gamma is formed between every two adjacent line segments; the sliding sleeve is provided with a spring plate assembly, and a front part and a rear part of the needle tube seat are respectively provided with a front clamping device and a rear clamping device which are matched with the spring plate assembly. The taking needle capable of preventing the secondary acupuncture can avoid external dripping and pollution of residual blood, improves medical safety and reduces potential safety hazard of human bodies.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, and specifically relates to a blood sampling needle capable of preventing secondary acupuncture. Background technique [0002] A blood sampling needle is an instrument used to collect blood samples in the medical examination process. It is a disposable product. Its structure usually includes an input needle seat, a blood sampling needle, an output needle seat and a hose. The blood sampling needle is set on the input needle seat. The output needle seat is connected with the input needle seat through a hose, and the output needle seat is connected with the blood collection vessel. This kind of blood sampling needle, after the blood sampling needle acupuncture the patient and the blood sampling is completed, the blood sampling needle is not processed, and the blood sampling needle is exposed. If the blood sampling needle is not handled properly, it is very easy to cause the blood sampling needle ...
