[0002] A micro blood collection tube is a device used to collect blood samples from patients. A micro blood collection tube generally consists of a venous blood collection needle, a blood collection hose, and a blood storage tube. When collecting blood from a patient, medical staff need to insert the blood collection needle at one end of the blood collection hose into the patient's vein, and insert the blood collection needle at the other end of the blood collection hose into the interior of the blood storage tube to guide the patient's blood into the blood storage tube.

[0003] The venous blood collection needle is mainly a disposable vacuum venous blood collection device used to collect blood samples during medical examinations. The venous blood collection needle consists of a needle holder, a connector, a puncture needle, a rubber part, etc. Among them, the needle holder facilitates medical staff to hold the venous blood collection needle by hand and perform puncture operations.

[0004] However, when the needle holder is connected to the blood collection tube, it is necessary to forcefully squeeze the needle into the needle holder, which is not convenient to operate. Therefore, it does not meet the existing requirements, and for this reason, we propose a micro blood collection tube holder that is convenient to operate. Content of the Utility Model

[0010] Preferably, a rubber gasket is inlaid on the inner side of the circular groove, and a plurality of anti-slip protrusions are provided at the bottom end of the rubber gasket.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By squeezing the two extrusion strips towards the middle, the extrusion strips drive the straight connecting piece and the second transfer strip to approach each other, causing the two bending connecting strips to bend and drive the two first transfer strips to move away from each other, expanding the bottom opening of the bending clamping strip until the width dimension of the bottom opening of the bending clamping strip is greater than the diameter dimension of the blood collection needle tip. Then, the blood collection needle tube is placed inside the bending clamping strip and the extrusion strip is released, causing the bending clamping strip to elastically recover and clamp and fix the blood collection needle tip. The operation is simple and fast, and during the operation, one hand operates the needle holder and the other hand places the blood collection needle tip, shortening the installation time of the blood collection needle tip and improving the assembly efficiency of the blood collection needle tip and the needle holder;

[0013] 2.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] As shown in Figure 1 and Figure 2 Figure 2 , a micro blood collection tube holder that is convenient to operate. A needle tube clamping groove 3 is provided on the bottom surface of the needle holder 1. The needle holder 1 includes a curved clamping strip 11. The curved clamping strip 11 is circularly curved and first connecting strips 12 are fixed on both sides. On the other side of the first connecting strip 12, a curved connecting strip 13 is fixed. On the other side of the curved connecting strip 13, a second connecting strip 14 is fixed. On the other side of the second connecting strip 14, a flat connecting piece 15 is fixed. On the other side of the flat connecting piece 15, an extrusion strip 16 is fixed. By squeezing the two extrusion strips 16 towards the middle, the extrusion strip 16 drives the flat connecting piece 15 and the second connecting strip 14 to approach each other, causing the two curved connecting strips 13 to bend and driving the two first connecting strips 12 to move away from each other, expanding the bottom opening of the curved clamping strip 11, facilitating the insertion of the blood collection needle tip into the needle tube clamping groove 3.

[0021] The side of the curved connecting strip 13 connected to the second connecting strip 14 is curved upward in an arc. The curved clamping strip 11, the first connecting strip 12, the curved connecting strip 13, the second connecting strip 14, the flat connecting piece 15, and the extrusion strip 16 are all made of plastic. The curved connecting strip 13 deforms by bending under force, so that the two first connecting strips 12 move away from each other and the width of the bottom opening of the curved clamping strip 11 increases.

[0022] As a preferred solution of this embodiment, as shown in Figure 3 Figure 3 , two symmetric anti - detachment limiting strips 17 are fixed on the inner side of the curved clamping strip 11. The anti - detachment limiting strips 17 are circularly curved and the center of the circle coincides with the center of the curved clamping strip 11. The anti - detachment limiting strips 17 support the blood collection needle tip clamped by the curved clamping strip 11 from below, preventing the clamped blood collection needle tip from falling off from the inner side of the curved clamping strip 11.

[0023] As a preferred solution of this embodiment, as shown in Figure 1 and Figure 4 Figure 4 , two symmetrically distributed hand - held pieces 2 are fixed on the upper surface of the needle holder 1. A circular groove is provided at the bottom of the large end of the hand - held piece 2. A rubber gasket 4 is inlaid inside the circular groove. A plurality of anti - slip protrusions 5 are provided at the bottom end of the rubber gasket 4. The rubber gasket 4 and the anti - slip protrusions 5 are used to increase the friction between the finger pulp of the medical staff's finger and the hand - held piece 2, preventing the hand - held piece 2 from falling off between the fingers of the medical staff.

[0024] Working principle: When it is necessary to assemble the blood collection needle tip with the needle holder 1, first, a medical staff member squeezes the two extrusion strips 16 towards the axis direction of the bending clamping strip 11 with one hand. The extrusion strips 16 drive the straight connecting piece 15, the second transfer strip 14, and the side edges of the bending connecting strip 13 that tilt upward to move simultaneously. At this time, the bending connecting strip 13 is stressed and bends, and the bottom end of the bending connecting strip 13 pulls the first transfer strip 12 towards the outside of the bending clamping strip 11, causing the two first transfer strips 12 to move away from each other and increasing the width of the bottom opening of the bending clamping strip 11 until the width of the bottom opening of the bending clamping strip 11 is sufficient for the blood collection needle tip to enter the bending clamping strip 11. At this time, the medical staff member uses the other hand to pass the blood collection needle through the two anti - detachment limit strips 17 and snap it into the needle tube clamping groove 3, and then releases the extrusion strips 16. At this time, the bending connecting strip 13 and the bending clamping strip 11 elastically reset, so that the bending clamping strip 11 and the two anti - detachment limit strips 17 clamp the blood collection needle tip, and the anti - detachment limit strips 17 support the blood collection needle tip from below. The operation is simple and fast, shortening the installation time of the blood collection needle tip and improving the assembly efficiency of the blood collection needle tip and the needle holder 1.
