Embodiment Construction

[0015] Such as figure 1 with figure 2 As shown, the safe drug dissolver provided by the present invention includes a needle 1, a needle holder 2, a needle tube 3, a needle tube holder 4, an air filter membrane 5, a liquid medicine filter membrane 7, and the like. The needle 1 and the needle holder 2 are similar to the common structure. exist figure 1 Among them, the orifice 10a of the liquid hole 10 of the needle 1 is located at the front end of the needle 1 . The liquid hole 10 orifice 10a of the needle 1 can also be positioned at the side of the front end of the needle 1, such as figure 2 The structure shown is used to prevent debris from being generated when the needle 1 is inserted into the rubber stopper. The needle tube 3 is fixed in the needle tube seat 4 , and the needle tube 3 is sleeved on the outside of the needle head 1 . But there is a certain gap between the needle tube 3 and the needle head 1, and this gap allows air to pass through. In this embodiment, ...

Said air hole at the side of needle tube seat has another filter membrane. Its advantages are dual filtration, and high safety.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drug dissolving and adding drug device. Background technique [0002] Currently, IV fluids and injections are the most commonly used treatments in medicine. Before the infusion, it is often necessary to mix some powder and glucose liquid or solution together. The specific operation method is: insert the syringe into the liquid medicine bottle to extract a small amount of liquid medicine; then pull out the syringe and insert it into the powder bottle, and inject the liquid medicine into the powder bottle; after the powder and liquid medicine are completely dissolved, draw out the mixed solution Inject into an infusion bottle or draw directly into a syringe. In the above dispensing process, because the medicine bottle is a sealed structure, a certain air pressure difference will be generated during operation, which makes the operation very labor...
