Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a syringe with a medicine storage function. Background Art

[0002] Syringes can also be used in medical equipment, containers, such as scientific instruments in some chromatography to inject through a rubber septum. Injecting gas into a blood vessel will cause air embolism. The method to remove air from the syringe to avoid embolism is to invert the syringe, gently tap it, and then squeeze out a little liquid before injecting it into the bloodstream.

[0003] Currently, when injecting drugs for patients through a syringe, it is necessary to first draw out the injection liquid in the medicine bottle and then inject it into the patient. When the medicine bottle is an ampoule bottle, it is difficult to open, which increases the injection difficulty. Moreover, when there are many patients, repeatedly opening the bottle makes the injection process time-consuming and laborious, with a large labor intensity. Based on these problems, Chinese Patent CN219440262U discloses a syringe with a medicine storage function, which sets the injection part and the medicine storage part into an integrated structure, enabling the user to draw out the medicine liquid when pulling and pushing the medicine pushing component, saving the process of opening and handling the medicine bottle, being time-saving and labor-saving, and convenient to use. In addition, the syringe with a medicine storage function is also provided with a refrigerating component to control the temperature of the medicine liquid in the medicine storage part, thereby ensuring the medicine storage requirements and avoiding the denaturation or invalidation of the medicine liquid.

[0004] There is only one set of medicine storage cavity structure in this syringe, so it can only store one kind of medicine liquid. If it is necessary to mix multiple kinds of medicine liquids for use, it is still necessary to open and draw out the medicine liquid in other medicine bottles. This process is not only time-consuming and laborious, but also will hinder the treatment progress of patients. Summary of the Utility Model
