Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a novel medicine dispensing converter. Background Art

[0002] When patients receive an infusion, they often need to add some powdered drugs to mix. The process of manually preparing the liquid medicine is cumbersome. The saline bottle needs to be cut, disinfected and opened before the saline solution can be extracted with a syringe. This process is very labor-intensive for medical staff, especially when preparing anesthetics, which usually takes a lot of time. Especially for some major surgeries (such as heart and large blood vessel surgeries), more drugs need to be prepared, and more saline bottles are used. In addition, the mixed liquid medicine needs to be extracted and re-injected into the infusion bottle. The repeated insertion and removal of the needle increases the risk of finger punctures and easily causes needle contamination, which in turn causes cross infection. For this reason, we propose a new type of dispensing converter to solve the above problems. Utility Model Content

[0015] 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.

[0016] Example 1

[0017] Reference Figure 1 、 2 , which is the first embodiment of the present utility model, provides a novel dispensing converter, including a cylinder 1, a fixed disk 6 fixedly sleeved in the middle of the cylinder 1, and needle head 1 7 and needle head 2 8 coaxially fixedly sleeved on both sides of the fixed disk 6;

[0018] A plurality of movable grooves 5 are provided on the inner wall of one end of the cylinder 1 , and anti-dropping components 4 are movably provided in the movable grooves 5 . Annular grooves 2 are provided on the outer walls of both sides of the cylinder 1 , and sealing covers 3 are sleeved on the annular grooves 2 .

[0019] The sealing covers 3 are respectively sleeved on the annular grooves 2 on both sides of the cylinder 1, thereby sealing the two ends of the cylinder 1 and protecting the interior of the cylinder 1. When in use, the sealing covers 3 are respectively unplugged to expose the openings at both ends of the cylinder 1, and the cylinder 1 is held by hand, with the end with the movable groove 5 facing the saline bottle. Then the cylinder 1 is sleeved outside the bottle mouth of the saline bottle, and the cylinder 1 is moved toward the saline bottle so that the needle 7 is inserted into the rubber stopper of the saline bottle. When the cylinder 1 moves, the convex ring of the bottle mouth of the saline bottle hits the anti-falling component 4, and the anti-falling component 4 cooperates with the convex ring of the bottle mouth of the saline bottle to limit the cylinder 1 to prevent the cylinder 1 from falling off during the dispensing process. The other end of the body 1 is inserted into the mouth of the ampoule bottle for dispensing medicine, and the needle 2 8 is inserted into the rubber stopper of the ampoule bottle, thereby connecting the saline bottle and the ampoule bottle through the needle 1 7 and the needle 2 8. Then the saline bottle is located at the top and the ampoule bottle is located at the bottom. Under the action of gravity, the saline in the saline bottle flows into the ampoule bottle to achieve mixing of the medicine liquid. After the mixing is completed, the whole body is turned over so that the ampoule bottle is at the top and the saline bottle is located at the bottom, thereby allowing the mixed medicine liquid to flow back into the saline bottle, reducing the needling operation and improving the dispensing efficiency. At the same time, the needle 1 7 and the needle 2 8 are both located inside the barrel 1 to prevent the needle from pricking the hand during the dispensing operation.

[0020] Example 2

[0021] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, the sealing cover 3 and the annular groove 2 have an interference fit, and the interference fit facilitates the rapid disassembly and assembly of the sealing cover 3.

[0022] Specifically, the needle head 1 7 and the needle head 2 8 are symmetrically arranged and interconnected, and the interconnected manner facilitates the flow of the liquid medicine during cooperation.

[0023] Specifically, the anti-slip component 4 includes a connecting shaft 41, a clamping strip 42, a spring 43, and a cylindrical groove 44. The connecting shaft 41 is fixedly installed on one side of the movable groove 5. The connecting shaft 41 rotates to connect one side of the clamping strip 42. The other end face of the clamping strip 42 is fixedly connected to one end of the spring 43. The other end of the spring 43 is fixedly connected to the inner wall of the cylindrical groove 44. The cylindrical groove 44 is recessed in the inner wall of the other side of the movable groove 5, and the clamping strip 42 is movably arranged in the movable groove 5.

[0024] Furthermore, the clip 42 is an L-shaped structure. During use, the sealing cap 3 is removed to expose the openings at both ends of the barrel 1. The barrel 1 is held with the end provided with the movable groove 5 facing the saline bottle. The barrel 1 is then placed outside the mouth of the saline bottle and moved toward the saline bottle, causing the needle 7 to penetrate the rubber stopper of the saline bottle. As the barrel 1 moves, the convex ring of the saline bottle mouth contacts the anti-slip assembly 4. The clip 42 of the anti-slip assembly 4 slides against the convex ring of the saline bottle mouth, and the reaction force of the convex ring causes the clip 42 to move toward the movable groove 5. The clip 42 retracts into the movable groove 5, allowing the saline bottle mouth to be completely inserted into the barrel 1. When the convex ring moves past the engaging position of the clip 42, the elastic force of the spring 43 drives the clip 42 to move toward the body of the saline bottle. The clip 42 cooperates with the convex ring of the saline bottle mouth to limit the barrel 1 and prevent it from falling off during the dispensing process.

[0025] Example 3

[0026] Reference Figure 1-3 , which is a third embodiment of the present invention. This embodiment is based on the above two embodiments. The sealing cover 3 is respectively sleeved on the annular grooves 2 on both sides of the cylinder 1, thereby sealing the two ends of the cylinder 1 and protecting the interior of the cylinder 1. When in use, the sealing cover 3 is respectively pulled out to expose the openings at both ends of the cylinder 1. The cylinder 1 is held by hand, with one end provided with the movable groove 5 facing the saline bottle. Then the cylinder 1 is sleeved on the outside of the bottle mouth of the saline bottle, and the cylinder 1 is moved toward the saline bottle so that the needle 7 is inserted into the rubber stopper of the saline bottle. When the cylinder 1 moves, the convex ring of the bottle mouth of the saline bottle hits the anti-slip component 4, and the clip 42 of the anti-slip component 4 slides and hits the convex ring of the bottle mouth of the saline bottle. Then, under the reaction force of the convex ring, the clip 42 moves toward the movable groove 5, and the clip 42 retracts into the movable groove 5, so that the bottle mouth of the saline bottle is completely sleeved into the cylinder 1. When the convex ring moves past the clip 42 After the clamping position, the elastic force of the spring 43 drives the clamping strip 42 to move toward the body of the saline bottle. The clamping strip 42 cooperates with the convex ring of the bottle mouth of the saline bottle to limit the barrel 1 to prevent the barrel 1 from falling off. Then, the bottle mouth of the ampoule bottle for dispensing medicine is inserted into the other end of the barrel 1, and the needle 2 8 is inserted into the rubber stopper of the ampoule bottle, thereby connecting the saline bottle and the ampoule bottle through the needle 1 7 and the needle 2 8. Then, the saline bottle is located at the top and the ampoule bottle is located at the bottom. Under the action of gravity, the saline in the saline bottle flows into the ampoule bottle to achieve mixing of the medicine liquid. After the mixing is completed, the whole body is turned over so that the ampoule bottle is at the top and the saline bottle is at the bottom, thereby making the mixed medicine liquid flow back into the saline bottle, reducing the needling operation and improving the dispensing efficiency. At the same time, the needle 1 7 and the needle 2 8 are both located inside the barrel 1 to prevent the needle from pricking the hand during the dispensing operation.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
