[0005] Furthermore, the adjustment component includes a fixed block, an adjustment groove, and an adjustment gear. The blood transfusion tube is placed in the fixed block. The adjustment groove is opened on both sides of the inner wall of the fixed block and is inclined. Both ends of the adjustment gear are respectively installed in the adjustment groove for transmission. The flow rate in the blood transfusion tube can be controlled by adjusting the position of the adjustment gear in the adjustment groove.

[0006] Furthermore, a connecting cover is provided on a side of the blood storage bottle close to the blood transfusion tube, the connecting cover is threadedly connected to the blood storage bottle, and the blood storage bottle can be detached from the connecting cover.

[0007] Furthermore, two groups of fixing belts are arranged on both sides of the blood storage bottle, and both groups of fixing belts are provided with elastic material.

[0008] Furthermore, a holding plate is fixedly mounted on one side of the blood drawing needle, and the surface of the holding plate is provided with anti-slip patterns, and the anti-slip patterns are equidistantly mounted on the surface of the holding plate.

[0009] Furthermore, a scale bar is constructed on the surface of the blood storage bottle.

[0010] Furthermore, the material of the blood storage bottle is flexible.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The utility model can press the blood storage bottle before drawing blood. At this time, the pressure in the internal space of the blood storage bottle increases, so that the blood storage bottle can draw the patient's blood from the body through the blood transfusion tube. At the same time, the position of the adjusting gear in the adjusting groove is adjusted to control the flow rate in the blood transfusion tube, so that the blood drawing flow rate can be adjusted. This solves the problem that the blood drawing flow rate of the blood drawing tool is not adjustable when it is used. If the flow rate is too slow, the risk of blood coagulation in the blood collection bag will increase, making the blood sample unusable. Blood coagulation not only wastes blood resources, but also may cause unnecessary psychological and physiological pressure on blood donors. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0018] The present application provides an adjustable blood drawing tool, which is mainly used to solve the problem that the blood drawing flow rate of the blood drawing tool is not adjustable when it is used. If the flow rate is too slow, the risk of blood coagulation in the blood collection bag will increase, making the blood sample unusable. Blood coagulation not only wastes blood resources, but also may cause unnecessary psychological and physiological pressure on blood donors. The following technical solutions are provided. Figure 1-Figure 3 Make a detailed description:

[0019] like Figure 1-3As shown, an adjustable blood drawing tool comprises a blood storage bottle 1, a fixing belt 6 having a blood transfusion tube 2 arranged at one end of the blood storage bottle 1, a blood drawing needle 3 fixedly installed at the end of the fixing belt 6 blood transfusion tube 2 away from the blood storage bottle 1, an adjusting component 4 arranged on the outer wall of the fixing belt 6 blood transfusion tube 2, the fixing belt 6 adjusting component 4 can adjust the blood flow rate inside the blood transfusion tube 2, the fixing belt 6 adjusting component 4 comprises a fixing block 401, an adjusting groove 402, and an adjusting gear 403, the fixing belt 6 blood transfusion tube 2 is clamped in the fixing block 401, the fixing belt 6 adjusting groove 402 is arranged on both sides of the inner wall of the fixing block 401 and is inclined, the two ends of the fixing belt 6 adjusting gear 403 are respectively driven and installed in the adjusting groove 402, the flow rate in the fixing belt 6 blood transfusion tube 2 can be controlled by adjusting the position of the adjusting gear 403 in the adjusting groove 402, the fixing belt 6 blood storage bottle 1 is provided with a connecting cover 5 on the side close to the blood transfusion tube 2, the fixing belt 6 connecting cover 5 is threadedly connected to the blood storage bottle 1, the fixing belt 6 blood storage bottle 1 can be separated from the connecting cover 5, and the fixing belt Two groups of fixing belts 6 are also arranged on both sides of the blood storage bottle 1, and both groups of fixing belts 6 are arranged with elastic material. A holding plate 7 is fixedly installed on one side of the blood drawing needle 3 of the fixing belt 6, and an anti-slip pattern 8 is arranged on the surface of the holding plate 7 of the fixing belt 6. The anti-slip pattern 8 of the fixing belt 6 is equidistantly arranged on the surface of the hand-held plate. A scale bar 9 is also constructed on the surface of the blood storage bottle 1 of the fixing belt 6, and the material of the blood storage bottle 1 of the fixing belt 6 is flexible. In some embodiments, the blood storage bottle 1 can be pressed before blood drawing. At this time, the pressure in the internal space of the blood storage bottle 1 increases, so that the blood storage bottle 1 can draw the patient's blood from the body through the blood transfusion tube 2.
