Combined micro-pump control device
Technical Field
The invention relates to a micro pump control device, in particular to a combined micro pump control device.
Background
Microinjection is needed in the treatment process of a plurality of patients, the minimum rate of the microinjection can reach 0.1mL/h, but when the patients need to inject a plurality of medicines, the medicines are needed to be prepared once every time of injection, and the situation of untimely medicine preparation can occur due to the long microinjection time period, so that the treatment of the illness state of the patients is influenced. The reason that a drug needs to be prepared once per injection is that some drugs need to be stored in a constant temperature range (such as a certain temperature between 4 ℃ and 20 ℃) to ensure that the drugs have drug effects, which determines that a plurality of drugs cannot be prepared at one time and placed on the existing micro-injection device because the existing micro-injection device does not have a temperature control device and cannot maintain the drugs to be injected at a required temperature.
Furthermore, for some drugs injected before and after the patient, they cannot be mixed in the injection line, which requires flushing (commonly called flushing) the injection line after the first drug is injected, and the fluid used in flushing has different requirements, some of which require flushing with saline and some of which require flushing with sugar water, which makes sure that many drugs cannot be administered at once because there is no flushing function in the prior art microinjection apparatus.
