Abstract
The present invention provides a kind of anesthesia full-automatic micro-injection pump, including external rubber tube, Y connection, syringe pump main body tube, piezoelectric crystal plate, trunnion, piston head, microsprings, measurement of concetration head, injector head, controller, utilize the inverse piezoelectric effect of piezo-electric crystal, calculating control with hop controller, it is possible to achieve the accurate pump of droplet penetrates decoction；One-way fluid valve is provided with syringe pump, liquid backflow pollution can be prevented；Two-tube path is designed with, side pump penetrates substrate liquid, and side pump penetrates anaesthetic liquid, and concentration as needed sets respective pump firing rate rate, and then realizes matched proportion density after mixing, farthest reduces the waste of anaesthetic, is that patient is cost-effective；Using Automatic Control, the labor intensity of negative-feedback monitoring modular, farthest reduction medical personnel.
Description
Technical field
The present invention provides a kind of anesthesia full-automatic micro-injection pump, belongs to the anesthesia equipment field of medicine equipment.
Background technology
Micro-injection pump（Abbreviation micro pump）A kind of new pumping forces instrument, by a small amount of fluid it is accurate, it is micro, uniform, hold
Export continuously.By controller, executing agency and syringe composition.Micro-injection pump by a small amount of decoction it is accurate, it is micro, uniform, hold
It is pumped into vivo, simple operation, timing, quantifies continuously, is needed that drug concentration, speed can be adjusted at any time according to the state of an illness, medicine is existed
Effective blood drug concentration can be kept in vivo, with micro pump critical, can mitigate medical personnel's workload, improve work effect
Rate, assistance is accurate, safely, effectively implements to rescue.
Anesthesia can guarantee that patient carries out real-time, effective, accurate quantification as needed in anaesthesia process with micro-injection pump
Anesthesia, the burden and operation difficulty of medical personnel can be greatly reduced.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of anesthesia full-automatic micro-injection pump, it uses piezoelectric crystal plate
Inverse piezoelectric effect and realize droplet ejection, it is novel in design, unique.
The technical solution adopted by the present invention is：One kind anesthesia full-automatic micro-injection pump, including external rubber tube, bifurcated
Joint, syringe pump main body tube, piezoelectric crystal plate, trunnion, piston head, microsprings, measurement of concetration head, injector head, controller, its
It is characterised by：For described external rubber sleeve on the joint of Y connection, the merging joint of Y connection is rotated in injection
On the interface of pump main body tube, piezoelectric crystal plate is mounted in the unit with grooves in outer wall of syringe pump main body tube, and with diaphragm seal, it is ensured that no
Meeting leakage, trunnion are rotated in the other end of syringe pump main body tube, and piston head is slidably mounted on inside trunnion, microsprings one end top
Mounting seat in trunnion, other end top keep piston head to ride over the diminution of trunnion in the mounting post of piston head
On aperture surface；Measurement of concetration head is fixedly mounted in the big footpath needle tubing of injector head, the tail of the bigger diameter end spinning of injector head in trunnion
On end；Whole syringe is installed in the special groove of controller.
To realize the control to piezoelectric crystal plate, the interface that described piezoelectric crystal plate passes through control circuit access controller
It is interior.
To realize the real-time detection to mixed liquid concentration, described measurement of concetration head passes through external circuitses access controller
In interface.
Control process is calculated to realize, described controller is provided with concentration calculation module, drop is micro- penetrates control module, concentration
Feedback module and Operation display module.
To realize no pollution, the strict sealing of described complete equipment requirement, it is impossible to leakage.
The present invention uses above technical scheme, has advantages below：Can anti-non-return liquid pollution；Accurate fiber crops can be realized
Liquor-saturated drug administration, reduce and waste, reduce cost；The manipulation strength of medical personnel can be greatly reduced, greatly reduce maloperation band
The trouble come.

Embodiment
With reference to specific embodiment, the invention will be further described, the illustrative examples and explanation invented herein
For explaining the present invention, but it is not as a limitation of the invention.
As shown in Figure 1, Figure 2, Figure 3 shows, the full-automatic micro-injection pump of a kind of anesthesia, it is first when patient needs injecting anesthetic
First provided by anesthetist and anaesthetize the guide parameters such as dosage, time, in input controller 10, a termination on external rubber tube 1
Enter substrate liquid, one end access Anesthesia medicine liquid, injector head 9 is accessed in patient body by syringe needle；Controller 10 sends instruction, piezoelectricity
Crystal wafer 4 carries out bending extruding action, drop is pressurized and moves ahead, into trunnion 5 after top open piston head 6, mix in the injector head 9
Exported after uniformly, feed back to controller 10,10 concentration as requested of controller after the concentration of the first 8 detection admixing medical solutions of measurement of concetration
The operating frequency of both sides crystal piezoelectric patches 4 is adjusted in contrast with actual concentrations, it is ensured that actual concentrations are with requiring concentration control
In reasonable error, then export；During continuous narcosis, the regulation of medicine company concentration can be good with designed in advance, then basis
The Monitoring Data of patient is adjusted in real time.
