[0006] Furthermore, the limiting mechanism includes several plastic sheets fixedly mounted on one end of the limiting tube, the surfaces of the several plastic sheets are slidably sleeved with the same interference ring, the inner wall of the interference ring is provided with an interference groove, and also includes a driving mechanism, which is used to drive the interference ring to slide on the surfaces of the several plastic sheets while adjusting the distance between the thickened pad and one end of the limiting tube.

[0007] Furthermore, the driving mechanism includes a threaded groove opened on the surface of the limiting tube, the surface of the threaded groove is threadedly sleeved with a driving tube, one end of the driving tube is fixedly installed on one end of the resistance ring, and also includes a plurality of connecting rods, the two ends of the plurality of connecting rods are respectively fixedly installed on the surface of the driving tube and the thickened pad.

[0008] Furthermore, a T-shaped groove is provided at one end of the thickening pad.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. When the utility model is in use, the user limits the limiting tube to the surface of the blood outlet blood vessel of the blood transfusion bag through the limiting mechanism, and then inserts the sharp end of the blood transfusion device into one end of the thickened pad and then sequentially pierces the limiting tube and the blood outlet blood vessel of the blood transfusion bag to guide the blood inside the blood bag. With such a configuration, the user needs to pierce the thickened pad and the limiting tube before inserting the sharp end of the blood transfusion device into the blood outlet blood vessel of the blood transfusion bag, which can effectively reduce the length of the sharp end of the blood transfusion device inside the blood transfusion bag, thereby effectively preventing the blood transfusion bag from being pierced due to the excessive length of the puncture part of the blood transfusion device, and fully reflects the practicality of the device.

[0016] 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.

[0017] The present application provides a protector for preventing a blood transfusion bag from being punctured, which is mainly used to solve the problem that during blood transfusion, a user may puncture the blood transfusion bag with excessive force. At the same time, the puncture part of the current blood transfusion device is often made longer in order to puncture a variety of liquid storage devices. Therefore, the puncture part of the blood transfusion device of the user may puncture the inner wall of the blood transfusion bag, and provides the following technical solutions. Figure 1-Figure 4 Make a detailed description:

[0018] A protector for preventing a blood transfusion bag from being punctured comprises: a blood transfusion bag 1, a user slides a limiting tube 2 on the surface of the blood outlet of the blood transfusion bag 1, and then limits the position of the limiting tube 2 to the surface of the blood outlet of the blood transfusion bag 1 through a limiting mechanism 4, and at the same time, a thickening pad 3 is arranged at one end of the limiting tube 2, and the limiting mechanism 4 arranges the thickening pad 3 at one end of the limiting tube 2, and the user slides the puncture part of the blood transfusion device 5 to the thickening pad 3, the limiting tube 2, and one end of the blood outlet of the blood transfusion bag 1 in sequence to complete the operation The main components of the limiting mechanism 4 are: a plurality of plastic sheets 401 fixedly mounted on one end of the limiting tube 2. The user drives the contact ring 402 slidably sleeved on the surface of the plurality of plastic sheets 401 through the driving mechanism 6, so that the contact groove 403 on the inner wall of the contact ring 402 contacts the surface of the plurality of plastic sheets 401, so that one end of the contact sheet contacts the surface of the outlet blood vessel of the blood transfusion bag 1, thereby realizing the limiting of the limiting tube 2. At the same time, the driving mechanism 6 can also drive the thickening pad 3 to move.

[0019] When in use, the user limits the limiting tube 2 to the surface of the blood outlet blood vessel of the blood transfusion bag 1 through the limiting mechanism 4, and then inserts the sharp end of the blood transfusion device 5 into one end of the thickened pad 3 and then sequentially pierces the limiting tube 2 and the blood outlet blood vessel of the blood transfusion bag 1 to guide the blood inside the blood bag. With such a configuration, the user needs to pierce the thickened pad 3 and the limiting tube 2 before inserting the sharp end of the blood transfusion device 5 into the blood outlet blood vessel of the blood transfusion bag 1, which can effectively reduce the length of the sharp end of the blood transfusion device 5 inside the blood transfusion bag 1, thereby effectively preventing the blood transfusion bag 1 from being pierced due to the excessively long puncturing part of the blood transfusion device 5, thereby fully reflecting the practicality of the device.

[0020] like Figure 3 As shown, in some embodiments, in order to further optimize the solution, the main components of the driving mechanism 6 are: a threaded groove 601 opened on the surface of the limiting tube 2, and a driving tube 602 is threadedly sleeved on the surface of the threaded groove 601. At the same time, one end of the driving tube 602 is fixedly installed on one end of the resistance ring 402. The user rotates the driving tube 602 to drive the resistance ring 402 to move. At the same time, the driving tube 602 is fixedly installed on the thickening pad 3 through a plurality of connecting rods 603, which will drive the thickening pad 3 to move, thereby adjusting the length of the sharp end of the blood transfusion device 5 inside the blood transfusion bag 1. One end of the thickening pad 3 is provided with a T-shaped groove 7 for limiting the position of the sharp end of the blood transfusion device.
