Before injecting the patient, the drug needs to be prepared with a syringe in the pharmacy, the drug is drawn into the syringe, and then goes through the verification and inspection process. After passing the inspection, it is transported to the ward. Usually, it needs to be stored for a short time at the ward nurse station and then distributed to patients in each bed for injection. In this process, it undergoes multiple transfers and storage. If the drug leaks at any stage, it will cause personal injury.

[0003] The most common accidents in actual experience are excessive vibration during transportation or deviation in the gripping position during handling, which causes the needle plug in the syringe to fall off. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 A syringe fixing bracket in this embodiment is used to fix the syringe, improve the stability of the syringe when transferring, and avoid leakage of medicine inside the syringe;

[0026] Specifically, it includes at least two positioning rulers 1, one of which is attached to the lower surface of the other positioning ruler 1; at least two slide bars 3 are installed on the lower surface of the upper positioning ruler 1, and the two slide bars 3 are arranged in parallel, and the lower positioning ruler 1 is slidably connected between the opposite sides of the two slide bars 3; the outer sides of the two positioning rulers 1 are installed with clamping components 4, which are used to fix the syringe and the needle bolt respectively.

[0027] In actual use, the syringe containing the drug is placed on two positioning rulers 1, the length of the two positioning rulers 1 is adjusted according to the length of the syringe, and the needle plug and syringe on the syringe are fixed respectively by two clamping components 4 to ensure that the syringe and the needle plug will not move relative to each other during transportation.

[0028] In detail, in order to achieve the fixation of the syringe and the needle bolt, one of the clamping assemblies 4 in this embodiment includes at least two clamping parts, one of which includes at least two mounting blocks 401, the two mounting blocks 401 are assembled on one side of the positioning ruler 1, and a connecting shaft 402 is arranged between the opposite sides of the two mounting blocks 401, a sleeve 403 is rotatably connected to the outer side of the connecting shaft 402, and a clamping plate 405 is integrally formed on the upper side of the outer surface of the sleeve 403; torsion springs 404 are installed at both ends of the sleeve 403, and the two torsion springs 404 are respectively connected to the two mounting blocks 401, so that the torsion spring 404 can drive the clamping plate 405 to rotate when rebounding.

[0029] During actual use, the two relative splints 405 are first rotated back to back so that the gap between the two splints 405 can be used for the syringe or needle plug to be placed, and then the two splints 405 are loosened. At this time, the two torsion springs 404 rebound and drive the two splints 405 to move, so that the two splints 405 are simultaneously attached to the outside of the needle tube, thereby fixing the needle tube.

[0030] Furthermore, in order to adapt to the shapes of the outer surfaces of the syringe and the needle plug, the side cross-section of the clamping plate 405 in this embodiment is in an arc shape.

[0031] In actual settings, the clamping plate 405 with an arc-shaped cross section can better adapt to the shape of the outer surface of the syringe and the needle plug, ensuring the fit between the clamping plate 405 and their surfaces, thereby more firmly fixing the syringe and the needle plug and improving the accuracy and reliability of assembly.

[0032] Furthermore, in order to increase the friction between the clamping plate 405 and the needle tube, a rubber plate is installed on the inner side of the clamping plate 405 in this embodiment, and the shape of the rubber plate is adapted to the shape of the inner side of the clamping plate 405.

[0033] During actual setting, the rubber plate has good grip, which can effectively reduce the possibility of the splint 405 sliding on the surface of the needle tube, prevent displacement or instability during assembly, and thus make it easier to achieve accurate assembly. In addition, the rubber material is soft and elastic, and can provide a certain buffering and protection when the splint 405 contacts the needle tube, reducing possible scratches or damage to the surface of the needle tube and extending the service life of the needle tube.

[0034] It should be noted that, in order to prevent the needle tube from moving left and right, baffles 5 are installed on the two positioning rulers 1, and the needle tube is fixed between the two baffles 5.

[0035] In addition, in order to ensure uniform clamping force on the needle tube, the two clamping members in this embodiment are preferably symmetrically distributed on the front and rear sides of the positioning ruler 1, and the length of the right clamping plate 405 is greater than that of the left clamping plate 405.

[0036] Further preferably, in order to facilitate opening of the two clamping plates 405 , a driving plate 406 is installed on the lower side of the outer surface of the sleeve 403 , and the driving plates 406 on the front and rear sides are distributed in an eight-shaped shape.

[0037] In actual use, by pressing the two driving plates 406 at the same time, the two clamps 405 can be rotated in opposite directions, so as to open the two clamps 405, and when the needle tube is fixed between the two clamps 405, the driving plate 406 can be placed on the table as a supporting foot to improve the stability of the needle tube when it is placed.

[0038] See also Figure 2-3 In order to fix the two positioning rulers 1, a connecting plate 6 is installed between the opposite sides of the two slide bars 3, and the connecting plate 6 is attached to the lower surface of the lower positioning ruler 1; a fastener 2 with one end abutting against the lower positioning ruler 1 is connected to the internal thread of the connecting plate 6.

[0039] In actual use, the fastener 2 is rotated so that one end of the fastener 2 abuts against the connecting plate 6 , thereby fixing the lower positioning ruler 1 with the upper positioning ruler 1 , thereby locking the length between the two positioning rulers 1 .
