Background technique

Dispensing means adding a certain ingredient, applying a certain medicine, or treating it with a certain medicine to one or several known quantities of medicine.

When dispensing medicine, a syringe is used to deliver medicine into the infusion bottle. Generally, the needle on the syringe is inserted directly into the stopper of the infusion bottle, and then the medicine is injected. However, with this method of dispensing, when medicine is added multiple times, the medicine will Puncturing the stopper of an infusion bottle multiple times can easily lead to a reduction in the sealing performance of the infusion bottle, which may even lead to leakage. Moreover, puncturing the stopper multiple times can easily produce particles that may affect the medicine. In addition, some powdered medicines are placed in bottles with a large negative pressure in clinical practice. When inhaling after injecting saline solution and dissolving them, it is difficult to aspirate them out due to the negative pressure. Under normal circumstances, clinical nurses will pull out the syringe, suck out a little air and put it into the medicine bottle. Although this can help aspirate the dissolved medicine, it also increases the number of punctures of the bottle stopper and the risk of infection. .

Therefore, it is necessary to design and modify the medical devices used in dispensing to effectively prevent the stopper of the infusion bottle from being punctured multiple times.
