Referring to Figures 1 to 3, an embodiment of the present application provides an automatic blood sampling device, including a gun-type hand-held handle 1, the gun-type handle includes a handle rod and a handle support, the upper side end surface of the handle rod is integrally formed with a front support 2 and a rear support 3 for placing a syringe 9, the front support 2 and the rear support 3 are provided with a first clamping member 4 and a second clamping member 5 for clamping the head end and the tail end of the syringe 9, and the syringe 9 is fixed to the gun-type hand-held handle 1 by the first clamping member 4 and the second clamping member 5. In this embodiment, the first clamping member 4 includes a pair of front C The front C-type clamp 401 plate is symmetrically rotated on the opposite sides of the front support 2 with the central axis of the front support 2 as the axis, and the second clamping member 5 includes a pair of rear C-type clamp 501 plates. The rear C-type clamp 501 plates are symmetrically rotated on the opposite sides of the rear support 3 with the central axis of the rear support 3 as the axis, and each rear C-type clamp 501 plate is provided with a C-shaped gap along its arc direction, and the tail stock of the syringe 9 is placed in the C-shaped gap, and the rear C-type clamp 501 seat is used to limit the forward and backward movement of the syringe 9.

At the same time, in the present embodiment, the front support 2 and the rear support 3 are also provided with adjusting members for making the first clamping member 4 and the second clamping member 5 open and close synchronously, and the adjusting members include two movable rotating shafts 10 parallel to each other and a fixed shaft 11 located on the center line of the face shape between the movable rotating shafts 10, wherein both ends of the movable rotating shaft 10 pass through the front support 2 and the rear support 3, and maintain a rotational connection between the front support 2 and the rear support 3, and the front C-type clamp 401 plate and the rear C-type clamp 501 plate are fixedly mounted on the movable rotating shaft 10, and when the movable rotating shaft 10 rotates inward or outward, it can simultaneously drive the front C-type clamp 401 plate and the rear C-type clamp 501 plate at both ends to open and close. Of course, in order to facilitate the rotation of the movable rotating shaft 10 during operation, as shown in Figure 1, an L-shaped operating arm 13 is fixedly sleeved in the middle of each movable rotating shaft 10. When the first clamping member 4 and the second clamping member 5 need to be opened, the L-shaped operating arms 13 on both sides only need to be pinched together by hand to place the syringe 9 on the front support 2 and the rear support 3. In order to enable the opened first clamping member 4 and the second clamping member 5 to be able to close and clamp the syringe 9, a torsion spring 12 is sleeved on one end of the fixed shaft 11 close to the tail of the syringe 9. The two end legs of the torsion spring 12 are fixedly connected to the movable rotating shaft 10 on both sides respectively. When the L-shaped operating arms 13 on both sides are released, the movable rotating shaft 10 closes and clamps the syringe 9 again under the action of the torsion spring 12.

In some embodiments, a piston is provided in the syringe 9, and the piston is connected to the piston rod 15. There is a round stopper at the end of the piston rod 15. The gun handle has a hollow inner cavity, and an automatic telescopic member 6 is installed in the inner cavity. The automatic telescopic member 6 is parallel to the syringe 9 and extends toward one side of the buttstock. A third clamping member 7 is fixed to the output end of the automatic telescopic member 6. The third clamping member 7 includes a connecting arm 701 and a U-shaped clamp 702. One end of the connecting arm 701 is fixedly connected to the output end of the automatic telescopic member 6, and the other end of the connecting arm 701 is integrally formed with the U-shaped clamp 702. The U-shaped clamp 702 clamps the piston rod 15 and abuts against the round stopper, so that after the automatic telescopic member 6 is extended, the third clamping member 7 is driven to pull the piston rod 15 backward. In order to provide space for the movement of the third clamping member 7, the gun handle is extended to one side of the buttstock with an avoidance groove 14, and the avoidance groove 14 allows the third clamping member 7 to move forward and backward. Of course, it is understandable that in order to facilitate the control of the automatic telescopic part 6, a control switch 8 for controlling the activation of the automatic telescopic part 6 is provided at the bend between the gun handle and the butt of the gun-type hand grip 1. As a feasible implementation, the automatic telescopic part 6 can be a conventional electric telescopic rod.

From the above content, it can be seen that the automatic blood collection device provided in the embodiment of the present application is used in the following way: the medical staff uses it to pinch the L-shaped operating arm 13 towards the middle to open the first clamping member 4 and the second clamping member 5 at the same time, and then places the syringe 9 on the front support 2 and the rear support 3, and releases the L-shaped operating arm 13. Under the action of the torsion spring 12, the movable rotating shaft 10 is reset to drive the first clamping member 4 and the second clamping member 5 to close and clamp the syringe 9, and then the blood collection needle is punctured and pressed to fix it, and then the control switch 8 is pressed by hand, and the automatic telescopic member 6 drives the third clamping member 7 to pull the piston rod 15 backward, thereby completing the blood collection. It can be seen that by designing the gun-type hand-held handle 1, it is convenient for medical staff to hold and operate, and a front support 2 and a rear support 3 for placing the syringe 9 are arranged on the gun-type hand-held handle 1, and a first clamping member 4 and a second clamping member 5 are arranged on the front support 2 and the rear support 3 to fix the syringe 9, and the third clamping member 7 is driven by the automatic telescopic member 6 to clamp the piston rod 15 and move it backward to complete automatic blood sampling, which greatly reduces the workload of medical staff and has the advantages of saving time and effort and being easy to use.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
