Abstract
The utility model discloses an electronic medicine dispenser includes motor and motor monitoring devices, motor monitoring devices sets up in electronic medicine dispenser's internal circuit, detects electric current / voltage and falls or risees and stop the motor and operate. Through the operation of motor monitoring devices control motor, extraction of effective control liquid or exhaust, the formation of medicament foam is many in the solution injection phase, the air extraction is many, exhaust medicine spill scheduling problem.
Description
Technical field
This utility model relates to the dispensation apparatus in a kind of venous transfusion, and especially electronic dispenser, belongs to technical field of medical instruments.
Background technology
At present, venous transfusion is the administering mode comparatively commonly used, and medicament is deposited in cillin bottle usually in powder form, and normal saline is deposited in ampoule bottle.During operation, first extract physiological saline with syringe and dissolve medicated powder to cillin bottle, again extract afterwards and be expelled in infusion bottle.Nurse constantly will repeat above-mentioned process of making up a prescription every day, and its labor intensity is large, efficiency is low.In order to save muscle power, raise the efficiency, there is electronic dispenser.But the electronic dispenser used at present because of its operation sense poor, the trickle sense of touch such as can not to take out to the greatest extent, air drains to react liquid medicine, and can not extract reliably and cause medicament foam in the injection phase to generate the problems such as many, air extraction is many, aerofluxus medicine spills with aerofluxus.
Utility model content
Can not extract the problem with aerofluxus reliably to overcome existing electronic dispenser, this utility model provides a kind of intelligent electric dispenser, solve extraction and Exhaust Gas time foam, spill problem.
This utility model solves the problems of the technologies described above adopted technical scheme: electronic dispenser, comprise motor and motor monitoring device, described motor monitoring device is arranged in the internal circuit of electronic dispenser, detects that current/voltage falls or raises and stops motor running.
Described motor monitoring device comprises extraction relay, extracts current/voltage detector, discharges relay, discharges current/voltage detector and compare executor, extract relay closes, motor rotates forward extracting liquid, extract current/voltage detector and detect that current/voltage falls, relatively executor is judged as being drawn into air, extraction relay disconnects, motor stall; Discharge relay closes, motor rotates backward, and when discharge current/voltage detector detects that current/voltage raises, compares executor and is judged as that air drains, discharge relay and disconnect, motor stall.
The beneficial effects of the utility model are the changes having electronic monitoring device to monitor voltage, electric current in motor running in electronic dispenser, during extracting liquid, once find time, gas density and viscosity little, the resistance of ducting diminishes instantaneously, and device can detect that current/voltage falls, thus judges to find time, stop motor running, stop taking out medicine.In like manner, during aerofluxus, the resistance of ducting becomes large, and device detects that current/voltage raises, and judges that aerofluxus completes, and stops motor running, terminates aerofluxus.Its reasonable in design can reduce in extraction process, air excess extracts and causes medicament foamed problem, reduces in exhaust process and discharges the excessive medicinal liquid sputtering problem caused.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
Fig. 2 electrical schematic diagram of the present utility model.
In figure, 1. extract key switch, 2. extract relay, 3. extract current/voltage detector, 4. discharge key switch, 5. discharge relay, and 6. discharge current/voltage detector, 7. motor, 8. compares executor, 9. power supply.
Detailed description of the invention
As shown in Figure 1, electronic dispenser of the present utility model is powered by controlling power supply 9, and motor 7 is powered by motor power 10.Extract switch 1 when pressing, extract relay 2 and close, motor 7 rotates forward, detect that current/voltage falls when extracting current/voltage detector 3 during extracting liquid, relatively executor 8 is judged as being drawn into air, extracts relay 2 and disconnects, motor stall.Press and discharge key switch 4, discharge relay 5 and close, motor 7 rotates backward, and when discharge current/voltage detector 6 detects that current/voltage raises, compares executor 8 and is judged as that air drains, discharge relay 5 and disconnect, motor stall.
As shown in Figure 2, control the positive pole two-way in parallel of power supply 9, after K switch 1 is extracted in a road series connection, executor 8 is compared in access, and after another road series connection waste cock K2, executor 8 is compared in access, the coil one end extracting relay K A1 connects compares executor 8, the negative pole of other end connection control power supply 9; The coil one end of discharging relay K A2 connects compares executor 8, the negative pole of other end connection control power supply 9; Extraction current/voltage sensor 3 is all connected with discharge current/voltage sensor 6 and compares executor 8, and the negative pole of the equal connection control power supply 9 of the other end.The positive pole of motor power DC connects the normally opened contact extracting relay K A1, and series connection connects motor M after extracting current/voltage sensor 3; The positive pole of motor power DC connects the normally opened contact of discharging relay K A2, and series connection is discharged current/voltage sensor 6 and connected motor M.
