Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a chemical medicine device. BACKGROUND

[0002] For clinical nurses, after obtaining the medicine provided by the patient or the medicine list required by the physician, they usually need to add different medicines alone or in combination into sodium chloride or glucose injection, especially some powders are difficult to dissolve, and usually need to be repeatedly pumped to complete the operation. Especially for the nurses on night shift, when the workload is large, some medicines may not be pumped clean, causing waste of medicines and imbalance of the proportion of medicines. For some medicines that are not easy to dissolve, even an oscillator needs to be used, which is more troublesome. In addition, if the air in the medicine bottle is not discharged, it is also difficult to make a large amount of injection enter the bottle to dissolve the medicine.

[0003] Chinese Patent No. CN111135081B, entitled "Hand-operated and self-operated operating department chemical medicine machine", discloses a chemical medicine machine. However, the device only provides a pumping structure and does not provide a shaking action like a nurse, which cannot make the medicine dissolve more fully, uniformly and quickly, and may exist in the case of insufficient dissolution.

[0004] Chinese Patent No. CN210750285U, entitled "Needle-free sealed chemical medicine device", discloses a chemical medicine device. Although the device can realize the process of sealed chemical medicine, it does not solve the problem of how to completely transfer the medicine into the infusion bag, and there may be a large amount of residue. In addition, it does not consider how to make the medicine dissolve fully, quickly and uniformly. Practical new type content

[0005] The present application provides a chemical medicine device to at least solve the technical problem of insufficient dissolution in the prior art.

[0006] A chemical medicine device, comprising a mounting part and a driving part, the mounting part is provided with a plurality of mounting positions capable of fixing one or more of a medicine bottle, a needle cylinder or an injection container, and the driving part is provided with a manual foot pedal or an electric driving device capable of driving the mounting part to swing back and forth, and the driving part is capable of driving the piston handle of the needle cylinder to move.
