Abstract
The invention discloses an electric dosage device which comprises a motor and a motor monitoring device. The motor monitoring device is arranged at an internal circuit of the electric dosage device and stops the motor to operate when detecting that current/voltage decreases or increases. The motor monitoring device controls operation of the motor. Liquid extraction or air exhausting is effectively controlled. The problems that during the injection period, a lot of medicine bubbles are generated, much air is extracted, and medicine splashes out in the air exhaust process are resolved.
Description
Technical field
The present invention relates to the dispensation apparatus in a kind of venous transfusion, 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.
Summary of the invention
The problem with aerofluxus can not be extracted reliably in order to overcome existing electronic dispenser, the invention provides a kind of intelligent electric dispenser, solve extraction and Exhaust Gas time foam, spill problem.
The present invention 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 invention has the beneficial effects as follows in electronic dispenser the change having electronic monitoring device to monitor voltage, electric current in motor running, 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.

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 invention 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.
