Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a blood transfusion device with a locking structure. Background Art

[0002] A blood transfusion set is an infusion device that establishes a pathway between blood and veins. It consists of a bottle insertion needle, an air inlet needle or air inlet hole (optional, contains an air filter), a needle cap, a Y-shaped three-way pipeline (optional, the hose on the pipeline also has a flow-stop clamp), a dropper (the dropper contains a blood filter), a pipeline, a dosing port (optional), a flow regulator, an injection piece (optional), and an intravenous needle or injection needle of No. 7 (22G) or above (optional).

[0003] A blood transfusion device with the publication number CN210963371U includes a Y-shaped catheter, and the Y-shaped catheter branch is respectively connected to a saline bottle needle and a blood transfusion bag needle; the end of the Y-shaped catheter main tube is provided with a connector connected to an indwelling needle or a scalp needle; it is characterized in that: the blood transfusion bag needle includes a needle seat and a needle body; it also includes a needle sleeve that is sleeved on the outside of the needle body, and the needle body can be retracted inside the needle sleeve. The blood transfusion device with the above structure is provided with a needle sleeve on the blood transfusion bag needle, which can serve as a protective sleeve to prevent the needle from being contaminated when the needle is not in use. The needle is retractable, so it is convenient to adjust the length of the part of the needle exposed to the needle sleeve, which is used to adapt to blood transfusion bags of various models and specifications. It prevents the exposed part of the needle from being too long, causing the blood transfusion bag to be punctured. However, the existing device still has some shortcomings. The existing device lacks a locking structure. After the injection needle is inserted, the entire device cannot be fixed and will shake. If the user moves too violently, the needle tube will fall off, affecting the user. In addition, the existing device lacks an anti-slip mechanism. Since the surface of the blood transfusion channel is relatively smooth, sliding will affect the normal operation of the device. Therefore, we propose a blood transfusion device with a locking structure to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 The utility model provides an embodiment of a blood transfusion device with a locking structure, comprising a blood transfusion device tube 1, a locking mechanism 2 being provided on the surface of the blood transfusion device tube 1, and an anti-slip mechanism 3 being provided inside the locking mechanism 2;

[0025] The locking mechanism 2 includes a first fixing block 210, which is disposed on the surface of the blood transfusion tube 1. A second fixing block 220 is fixed to the surface of the first fixing block 210, and a third fixing block 230 is disposed on the surface of the second fixing block 220. A binding strap 240 is mounted on the surface of the third fixing block 230. A fourth fixing block 250 is fixed to the surface of the second fixing block 220, and a first connecting rod 260 is inserted into the interior of the fourth fixing block 250. A rotating block 270 is fixed to the surface of the first connecting rod 260.

[0026] The anti-slip mechanism 3 includes a second connecting rod 310, which is fixed inside the first fixing block 210. A third connecting rod 320 is inserted into the second connecting rod 310, a spring 330 is provided on the surface of the third connecting rod 320, and a fifth fixing block 340 is fixed to the surface of the third connecting rod 320.

[0027] The interior of the third fixing block 230 is provided with a sliding groove adapted to the fourth fixing block 250. The fourth fixing block 250 is inserted into the interior of the third fixing block 230, so that the second fixing block 220 can be fixed inside the third fixing block 230 and slide along the third fixing block 230 to adjust the fixed position of the blood transfusion tube 1. The first fixing block 210 is fixed to the surface of the fourth fixing block 250. The height of the fourth fixing block 250 is lower than the plane height of the third fixing block 230. The surface of the first connecting rod 260 is provided with a thread. The interior of the fourth fixing block 250 is provided with a threaded hole adapted to the first connecting rod 260. The first connecting rod 260 is inserted into the interior of the fourth fixing block 250. The structure of the fourth fixing block 250 enables the rotating block 270 to contact the third fixing block 230 after the first connecting rod 260 is inserted into the interior of the fourth fixing block 250, thereby fixing the position of the second fixing block 220, so that the second fixing block 220 can be fixed after the position is adjusted.

[0028] The side of the spring 330 close to the second connecting rod 310 is fixedly connected to the second connecting rod 310, and the side of the spring 330 away from the second connecting rod 310 is fixedly connected to the fifth fixing block 340, so that the fifth fixing block 340 can be squeezed and fixed by the lowering of the blood transfusion pipe 1 under the action of the spring 330. The fifth fixing block 340 is fixed to the surface of the third connecting rod 320, and the side of the fifth fixing block 340 away from the second connecting rod 310 is an arc structure, so that the fifth fixing block 340 fits the blood transfusion pipe 1 more closely and is fixed more stably. A layer of rubber pad is provided on the surface of the fifth fixing block 340, and the fifth fixing block 340 is provided inside the first fixing block 210. When the fifth fixing block 340 conflicts with the blood transfusion pipe 1, the presence of the rubber pad can effectively prevent the blood transfusion pipe 1 from sliding.

[0029] Working principle: When the device is working, the fifth fixing block 340 is pulled toward the second connecting rod 310, and then the blood transfusion pipe 1 is passed through the first fixing block 210, and then the fifth fixing block 340 is loosened, so that the fifth fixing block 340 is lowered under the action of the spring 330 to fix the blood transfusion pipe 1 and prevent the blood transfusion pipe 1 from sliding. The third fixing block 230 is placed on the support rod or on the limb and then pressed on the support rod, and the strap 240 is fastened to perform the locking operation, so that the device can fix the blood transfusion pipe 1 and prevent the blood transfusion pipe from sliding. If the pipe 1 shakes or moves due to pulling, the rotating block 270 is rotated so that the rotating block 270 no longer conflicts with the third fixing block 230, and then the first fixing block 210 is pushed to make the second fixing block 220 slide inside the third fixing block 230. The fixed position of the blood transfusion pipe 1 can be adjusted for easy use. After adjustment, the rotating block 270 is tightened again to make it conflict with the third fixing block 230, so that the second fixing block 220 is fixed in position, and the blood transfusion pipe 1 is fixed in position. The above is the entire working principle of the utility model.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
