Description
Technical field
The present invention relates to injector for medical purpose technical fields, particularly, are related to that a kind of medical pulling out needle changes bottled syringe automatically
And its application method.
Background technique
Infusion, which refers to, inputs intracorporal large bolus injection liquid by intravenous drip, and injection is packaged in the infusion bottle of glass
In, not bacteriostatic agent.Drop speed is adjusted by infusion apparatus when use, continues and steadily inputs drug internal.
According to the difference of medication, it will use multiple infusion bottles in usual single infusion process, with the defeated of infusion channel
Liquid head can be initially inserted into one of infusion bottle, and the injection in infusion bottle can be flowed into from the infusion channel in infusion head
In the vein of patient.
But after the injection in one of infusion bottle has been injected, the head that needs to be infused is extracted from the infusion bottle,
Then infusion head is inserted into another infusion bottle again, and the operational motion is very simple for normal person, but it is defeated
During liquid, the hand of patient can prick injection needle, and the above-mentioned needle that pulls out changes bottle movement one-handed performance is very for patients
It is difficult.
Summary of the invention
In view of this, first purpose of the invention be to provide it is a kind of it is medical pulling out needle changes bottled syringe automatically, be suitable for
Patient carries out one-handed performance, and completion pulls out needle and changes bottle movement.
In order to solve the above-mentioned technical problem, the technical scheme is that it is a kind of it is medical pulling out needle changes bottled syringe automatically,
Including at least two infusion bottles, the injection housing made of transparent material, slid chamber, the injection are equipped in the injection housing
