Description

Technical Field

[0001] This invention relates to the field of drug mixing connector technology, and more particularly to a drug mixing connector. Background Technology

[0002] Currently, in clinical settings, medical staff frequently need to perform intravenous infusions. Before infusion, it is often necessary to mix two or more different medications. Existing methods typically involve mixing the medications in the same bottle, shaking it, and then drawing the mixture out with a syringe.

[0003] However, existing methods of mixing medications have the following drawbacks:

[0004] (1) After mixing the medicines in the same bottle and shaking them, some medicines will remain in the bottle, which will easily lead to waste of the medicines and poor practical performance.

[0005] (2) The cannula and support in the injection needle are connected by integral molding. However, due to the different finger sizes of each person, and the smaller support surface of some syringes, the support is inconvenient and uncomfortable to hold. Utility Model Content

[0006] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a drug mixing connector that can prevent drug residue in the syringe, avoid waste, and improve practicality.

[0007] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution:

[0008] A drug mixing connector includes a connecting cylinder, two horizontal plates symmetrically arranged on the left and right side walls of the connecting cylinder, a vertical plate fixedly arranged at the other end of the horizontal plates, a syringe symmetrically arranged on both sides of the connecting cylinder, a cannula that is inserted into the connecting cylinder through the syringe, two arc-shaped plates symmetrically arranged at the left and right ends of the outermost part of the syringe, a push rod that is inserted through the opening on the outer side of the syringe, a rubber piston located inside the syringe and fixedly connected to the push rod, and a support member arranged on the outside of the push rod.

[0009] Furthermore, a sleeve capable of being threadedly connected to the connecting cylinder is fixedly provided at one end of the syringe near the connecting cylinder.

[0010] Furthermore, the support member is detachably mounted on the push rod.

[0011] Furthermore, a disassembly cylinder is fixedly provided on the support member, and the disassembly cylinder is threadedly connected to the push rod.

[0012] Furthermore, a disassembly cylinder is fixedly provided on the support member. The disassembly cylinder and the push rod are detachably connected through a disassembly assembly. The disassembly assembly includes a through hole on the outer wall of the disassembly cylinder, a slot on the outer wall of the push rod corresponding to the through hole, a plug rod that passes through the through hole and can be inserted into the slot, a wedge block fixedly provided on the inner wall of the slot, and a threaded protrusion ring provided on the plug rod. The wedge block and the protrusion ring are engaged.

[0013] Furthermore, the wedge block is provided with a guide slope for guiding the convex ring into the slot.

[0014] Furthermore, a plurality of stabilizing blocks are uniformly fixed on the inner sidewall of the slot, and the stabilizing blocks abut against the convex ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) When using it, first pour two kinds of medicine into one of the syringes, then insert both tubes into the connecting tube to realize the flow between the two tubes, and then push and pull the two push rods back and forth to mix the medicine. Finally, the mixed medicine is delivered out through one of the syringes. This method can avoid the medicine remaining in the syringe, avoid waste, and improve practicality. Compared with the existing technology, it solves the technical problem that the medicine will stick in the bottle after the medicine is mixed and shaken, which will easily cause waste of medicine and poor practicality.

[0024] Example 1:

[0025] like Figures 1-3 As shown, this embodiment provides a drug mixing connector, which includes a connecting cylinder 3, two horizontal plates 2 symmetrically arranged on the left and right side walls of the connecting cylinder 3, a vertical plate 1 fixedly arranged at the other end of the horizontal plate 2, a syringe 4 symmetrically arranged on both sides of the connecting cylinder 3, a cannula 6 that is disposed through the syringe 4 and can be inserted into the connecting cylinder 3, a push rod 9 symmetrically arranged on the outermost side of the syringe 4, two arc-shaped plates 8 located at the left and right ends of the syringe 4, a rubber piston 7 that is disposed through the opening on the outer side of the syringe 4 and fixedly connected to the push rod 9, and a support member 11 disposed on the outer side of the push rod 9.

[0026] The mixing connector includes a connecting cylinder 3, two horizontal plates 2 symmetrically arranged on the left and right side walls of the connecting cylinder 3, a vertical plate 1 fixedly arranged at the other end of the horizontal plate 2, syringes 4 symmetrically arranged on the upper and lower sides of the connecting cylinder 3, a cannula 6 that can be inserted into the connecting cylinder 3 is provided through the syringe 4, two arc-shaped plates 8 symmetrically arranged on the left and right ends of the outermost side of the syringe 4, a push rod 9 is provided through the opening on the outer side of the syringe 4, a rubber piston 7 fixedly connected to the push rod 9 is provided inside the syringe 4, and a support member 11 is provided on the outside of the push rod 9. In use, first pour two kinds of medicine into one of the syringes, then insert both cannulas 6 into the connecting tube 3 to achieve flow between the two tubes. Then push and pull the two push rods 9 back and forth to mix the medicine. Finally, deliver the mixed medicine through one of the syringes 4. This method can avoid medicine residue in the syringe 4, avoid waste, and improve practicality. Compared with the existing technology, it solves the technical problem that medicine will remain in the bottle after mixing and shaking the medicine, which will easily cause waste and poor practicality.

[0027] Furthermore, a sleeve 5 that can be threadedly connected to the connecting cylinder 3 is fixedly provided on one end of the syringe 4 near the connecting cylinder 3. In this way, the syringe 4 can be securely connected to the connecting cylinder 3.

[0028] Furthermore, the support member 11 is detachably mounted on the push rod 9, and a disassembly cylinder 10 is fixedly mounted on the support member 11. The disassembly cylinder 10 is threadedly connected to the push rod 9. In this way, the support member 11 can be disassembled and replaced with support members 11 of different specifications, which is convenient to adapt to different people's fingers. Compared with the existing technology, this solves the technical problem that the cannula and support member 11 in the injection needle are connected by a one-piece molding method, but due to the different sizes of people's fingers, the support surface of the support member 11 on some syringes is small, resulting in inconvenient support and uncomfortable clamping.

[0029] Example 2:

[0030] like Figures 1-3As shown, this embodiment is an improvement on embodiment 1. A disassembly cylinder 10 is fixedly provided on the support member 11. The disassembly cylinder 10 and the push rod 9 are detachably connected through the disassembly assembly 19. The disassembly assembly 19 includes a through hole 13 on the outer wall of the disassembly cylinder 10, a slot 12 corresponding to the through hole 13 on the outer wall of the push rod 9, an insert rod 14 that can be inserted into the slot 12 through the through hole 13, a wedge block 16 fixedly provided on the inner wall of the slot 12, and a threaded protrusion ring 15 provided on the insert rod 14 so that the wedge block 16 and the protrusion ring 15 are engaged. When in use, simply press the insertion rod 14 and the convex ring 15. Installation is quick and convenient. However, disassembly is difficult due to the twisting method. This method allows for the disassembly of the support 11, making it easy to accommodate different fingers. Compared to existing technologies, this solves the technical problem that the cannula and support 11 in the injection needle are connected by an integral molding method, but due to the different sizes of each person's fingers, the support surface of the support 11 on some syringes is small, resulting in inconvenient support and uncomfortable clamping.

[0031] Furthermore, the wedge block 16 is provided with a guide ramp 17 for guiding the protruding ring 15 into the slot 12. The guide ramp 17 makes it easier for the protruding ring 15 to be squeezed in.

[0032] Furthermore, a number of stabilizing blocks 18 are evenly fixed on the inner wall of the slot 12, and the stabilizing blocks 18 abut against the protruding ring 15. The spaced stabilizing blocks allow the insertion rod 14 to be subjected to more balanced forces, thus making it more stable after connection.

[0033] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
