Description

Technical Field

[0001] The utility model relates to the technical field of blood sampling devices, in particular to a clamping type disposable blood sampling needle. Background Art

[0002] Blood specimens are used for biochemical examinations to assist in disease treatment and diagnosis, and are one of the essential tasks in medical care. The collection of blood specimens requires the use of a lancet. Before routine blood collection, the needle of the lancet is protected by a needle cap, and after blood collection, a needle cap is usually used to protect the needle to prevent the needle from being exposed and stabbing medical staff, making it less likely for medical staff to be infected with blood-borne diseases.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that the Chinese patent publication number: CN213189611U discloses a disposable blood collection needle including a first needle and a second needle, the first needle is sleeved with a first needle cover, the second needle is sleeved with a second needle cover, an infusion tube is connected between the first needle and the second needle, and a needle holding wing is connected to the surface of the first needle. In the process of putting the exposed first needle back into the first needle cover after blood collection, the medical staff grasps the needle holding wing on the first needle with one hand and grasps the end of the first needle cover close to the infusion tube with the other hand, and puts the first needle into the first protective groove through the first opening. Since the first opening is located outside the hand grasping the first needle cover and away from the direction of the first needle into the first protective groove, the hand avoids the tip of the first needle, thereby avoiding needle pricks and avoiding the medical staff from increasing the risk of infection of blood-borne diseases.

[0005] However, there are still some problems that need to be improved in the actual use of the above patent. The most obvious one is that it is not convenient to store and organize the blood collection needles after the blood collection, which leads to the blood collection needles being in disarray and not conducive to subsequent processing.

[0006] To this end, we proposed a clamp-type disposable blood collection needle to solve the above-mentioned drawbacks. Utility Model Content

[0007] The utility model aims to provide a clamping type disposable blood collection needle in order to solve the shortcomings in the prior art.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a clamping type disposable blood collection needle, comprising a first needle and a clamping assembly, one end of the first needle is installed with an infusion tube, and the other end of the infusion tube is installed with a connecting seat, and a second needle is installed on the connecting seat, the surfaces of the first needle and the second needle are both provided with needle covers, and the surface of the first needle is installed with a needle holding wing;

[0009] The clamping assembly consists of a first clamping plate, a second clamping plate, a storage slot, a hinge, a placement slot and a strong magnet. The first clamping plate is hinged to the second clamping plate by a hinge. The first clamping plate and the second clamping plate have storage slots on their opposite sides. The first clamping plate and the second clamping plate have placement slots on their opposite sides, and strong magnets are installed in the two placement slots.

[0010] Preferably, there are multiple storage grooves, and all of the multiple storage grooves are semicircular structures.

[0011] Preferably, the magnetic poles of the two strong magnets close to one end of each other have opposite polarities.

[0012] Preferably, the clamping assembly is made of PP.

[0013] Preferably, the storage trough is used in conjunction with an infusion tube.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the utility model, a clamping assembly is provided. After blood collection is completed, a needle cover is used to protect the needle, and then the infusion tube is clamped in the storage slot. Then the first clamping plate and the second clamping plate are put together, and then they are fixed with a strong magnet to complete the storage and sorting of the infusion tube, thereby reducing the space occupancy rate, avoiding messy storage, and facilitating subsequent processing. Secondly, the clamping assembly can be disassembled for disinfection and sterilization and then reused, thereby reducing the use cost. BRIEF DESCRIPTION OF THE DRAWINGS
