Description
Technical field
The present invention relates to technical field of medical instruments, specially a kind of micro dispensing injector with pin.
Background technology
At present, medical personnel generally carry out dispensing operation with disposable ordinary syringe, with ordinary syringe dispensing operation
When have the following disadvantages：First, ordinary syringe syringe outer wall is smooth, it is not easy to clamp；Second, manually operated, the error ratio to make up a prescription
It is larger, it is impossible to accurately to hold the ratio of medicine.Third, having liquor residue all the time in the nipple of syringe front end, decoction is easily caused
Waste；Fourth, medicine is inhaled out of sealed vial or easily makes to produce negative pressure in medicine bottle during injection into sealed vial or makes medicine bottle internal pressure
Power, make pumping decoction difficult, waste time and energy, efficiency is low.
The content of the invention
It is an object of the invention to provide a kind of micro dispensing injector with pin, is asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：A kind of micro dispensing injector with pin, including control dress
Put, the control device includes the second containment vessel, the inner chamber left part of second containment vessel be installed with controller, control by
Button and display, the display and control button are electrically connected with by wire and controller, second containment vessel it is interior
Chamber right part is installed with battery, and the battery is electrically connected with by wire and controller, and the control device passes through electricity
Line is fixedly connected with the first containment vessel, and the intracavity bottom of first containment vessel is installed with speed changer, the speed changer
Motor is installed with the upside of right part, the motor is electrically connected with by wire and controller, the inner chamber of the speed changer
In be movably installed with leading screw and guide rod, needle tubing is fixedly connected with the downside of first containment vessel, in the inner chamber of the needle tubing
It is movably installed with piston, the lower end of the needle tubing is installed with syringe needle, and the syringe needle includes installing pipe, under the installing pipe
Portion is installed with extraction tube and ventilation is managed.
Preferably, the guide rod is located at the both sides of leading screw, and the middle part and the lower end of leading screw and guide rod of the piston are consolidated
Fixed connection.
Preferably, the ventilation pipe is positioned at the right side of extraction tube, and the length for pipe of taking a breath is less than extraction tube.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is simple in construction, and control accuracy is high, continuous work
Reliably, micro extraction or injection are carried out to make up a prescription to medicine suitable for medical department, especially medical service is to patient
The work of special medicine continuous micro injection transfusion is carried out, improves the precision to make up a prescription., can be with by setting control device
Realize and micro extraction or injection accurately carried out to sample, improve the automaticity of device, by set extraction tube and
Ventilation pipe, it can avoid making producing negative pressure in medicine bottle or increase the pressure in the bottle so that light, quick, the time saving province of pumping decoction
Power；Liquor residue is not had, is avoided that liquid waste.
