DETAILED DESCRIPTION

[0022] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0023] A syringe-type vacuum glass blood collector according to an embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0024] Example 1

[0025] For easier understanding, see Figures 1 to 3 The utility model provides an embodiment of a syringe-type vacuum glass blood collector, comprising a blood collector body 1 and a blood collection tube 2. A cannula 9 is installed inside the blood collector body 1, and the blood collection tube 2 is clamped inside the blood collector body 1. A fixed blood collection mechanism is arranged inside the blood collector body 1. After the blood collection tube 2 is installed inside the blood collector body 1, the cannula 9 will penetrate the blood collection tube 2, so that the blood collection tube 2 is connected to the needle 6 through the cannula 9 and the telescopic hose 11. The blood collection tube 2 is a vacuum blood collection tube.

[0026] The fixed blood sampling mechanism includes a fixed frame 3, a mounting member 4, a telescopic hose 11 and a needle 6. The fixed frame 3 is fixedly mounted on the side wall of the blood sampling device body 1, the telescopic hose 11 is mounted inside the blood sampling device body 1, one end of the telescopic hose 11 is fixedly mounted inside the mounting member 4, the needle 6 is fixedly mounted inside the mounting member 4, the mounting member 4 is clamped on one side of the blood sampling device body 1, and the fixed frame 3 is composed of two arc-shaped members.

[0027] It should be noted that when in use, the blood collection device body 1 is installed on the patient's arm through the fixing frame 3, the mounting part 4 is taken out, the telescopic hose 11 is pulled out, and then the needle 6 is inserted into the vein. After that, the blood collection tube 2 is inserted into the blood collection device body 1. Blood can be collected, making the blood collection process more convenient, and the blood collection tube 2 can be fixed to prevent the blood collection tube 2 from moving and pulling the needle 6 to cause harm to the patient.

[0028] In some embodiments, Figure 2 As shown, a hand piece 5 is fixedly mounted inside the mounting piece 4 , and the needle 6 is connected to one end of the telescopic hose 11 .

[0029] It should be noted that, by providing the hand piece 5, the mounting piece 4 can be easily removed and the needle 6 can be controlled. By providing the telescopic hose 11, the needle 6 can still be connected to the blood collection device body 1 after the mounting piece 4 is moved.

[0030] Example 2

[0031] In some embodiments, Figure 2 , Figure 3 As shown, an adjusting mechanism is provided inside the blood collector body 1, and the adjusting mechanism includes a first gear 7 and a second gear 12. The first gear 7 is rotatably connected inside the blood collector body 1, and the second gear 12 is rotatably connected inside the blood collector body 1. The first gear 7 is meshed with the second gear 12. A connecting port 13 is provided on one side inside the second gear 12, and the connecting port 13 matches the cannula 9. A fixing piece 10 matching the connecting port 13 is fixedly installed inside the blood collector body 1, and one end of the telescopic hose 11 is fixedly installed inside the fixing piece 10. The side walls of the telescopic hose 11 and the first gear 7 are provided with a marking groove 8.

[0032] It should be noted that, by setting up the adjustment mechanism, the blood sampling tube 2 can be inserted into the blood sampling device body 1 before use. The connecting port 13 inside the second gear 12 does not correspond to the cannula 9. At this time, one end of the cannula 9 is in a sealed state, which can prevent the blood sampling tube 2 from leaking. When in use, the marking groove 8 is located at the center of the blood sampling device body 1 by rotating the first gear 7, and the connecting port 13 is located at the top of the cannula 9. At this time, the cannula 9 is connected with the telescopic hose 11 inside the fixing part 10 through the connecting port 13, so that blood drawing can be achieved. By rotating the first gear 7 to move the position of the connecting port 13, the blood sampling tube 2 can be easily replaced.

[0033] In the present invention, the blood collection tube 2, the needle 6 and the telescopic hose 11 are well-known components and will not be described in detail herein.

[0034] Working principle: Before use, insert the blood collection tube 2 into the blood collection device body 1. When in use, install the blood collection device body 1 on the patient's arm through the fixing frame 3, take out the mounting part 4, and then insert the needle 6 into the vein. Then rotate the first gear 7 to make the marking groove 8 located at the center of the blood collection device body 1, and make the connecting port 13 located at the top of the cannula 9. At this time, the cannula 9 is connected with the telescopic hose 11 inside the fixing part 10 through the connecting port 13, so that blood can be collected. When the next tube of blood needs to be collected, the connecting port 13 is staggered with the cannula 9 by rotating the first gear 7, and then another blood collection tube 2 is inserted into the blood collection device body 1 to complete the replacement.
