Description

Clinical thermometer initial point restorer

Technical field

Clinical thermometer initial point restorer is by clinical thermometer being applied vibration force, because the stress difference at the mercury slug two ends in the clinical thermometer makes it produce directed moving, reach the utensil that the mercury slug initial point resets, belonging to the medical apparatus technical field.

Background technology

At present, the clinical thermometer of selling on the market after human body is carried out thermometric, resets the mercury slug initial point with the method for artificial whipping, in operating process, the time have clinical thermometer to slip out of the hand and the situation of crash takes place, influence work and medical personnel's image.The centrifugal force of the electronic sedimentator of also favourable usefulness comes the whipping clinical thermometer, and the mercury slug initial point is resetted, but because the activity space of electronic sedimentator is bigger, uses inconveniently, fails wide popularization and application.

Summary of the invention

The purpose of this utility model provides a kind of method for oscillating that utilizes, because the stress difference at mercury slug two ends, the mercury slug that makes clinical thermometer flows to initial point vertically under the effect of vibration force, reaching the purpose that initial point resets, is a kind of small and exquisite, attractive in appearance, easy to use and safe instrument.

The utility model is hung tag by clinical thermometer patchhole, restorer housing, battery, vibrating arm, stress spring, stress adjusting screw, power light, oblique top face rotating head, electric control circuit plate, micromotor, photoelectric sensor, power switch, chamber dividing plate, motor bin, battery case, stress spring and control circuit board installation room, battery case lid and elasticity and constitutes.By the chamber dividing plate clinical thermometer patchhole, motor bin, stress spring and control circuit board installation room and several parts of battery case are made in the separation of clinical thermometer initial point restorer housing inner chamber.An end that is hinged on the vibrating arm on the dividing plate of chamber contacts with stress spring, the other end of vibrating arm contacts with oblique cam rotating head on being installed in micromotor, screw in a stress adjusting screw in the bottom of housing, in order to regulate the stress of the stress spring that top front places, stress spring is installed in the installation room inside of housing bottom, one end seat is pressed in the inner of adjusting screw, and the other end contacts with vibrating arm.Micromotor is installed in the motor bin of housing intracavity bottom, the electrical apparatus control circuit plate is installed in the installation room and is inserted on the dividing plate of chamber, in clinical thermometer patchhole bottom inside photoelectric sensor is housed, battery cell is inserted in the battery case, a battery case lid is housed on the battery mounting box collar extension, power light is installed on the top end face of housing, in case top one side one elasticity being housed hangs tag, hang restorer in order to card, one power switch is housed on the housing bottom outer wall, housing outer surface is pressed into decorative pattern, to beautify restorer.

The power light of the utility model control circuit, micromotor, timing circuit, main amplifier and photoelectric sensor are connected in parallel on the main circuit, the output terminal of main amplifier with have one regularly the timing circuit of capacitor C connect mutually, the input end of main amplifier is respectively with photoelectric sensor and be connected in parallel on resistance in series R on the main circuit ₃And R ₄Connect mutually, the other end of timing circuit connects mutually with driving transistors on being serially connected in micromotor, and power supply automatic shutdown circuitry and power switch are connected on the main circuit, resistance R ₁And R ₂Be serially connected on the photoelectric sensor resistance R ₅Be connected on the power light.

During use, the energising of power turn-on master switch, medical rod-type clinical thermometer is inserted in the clinical thermometer patchhole of the present utility model, and the bottom is pressed on the vibrating arm at the bottom of the hole, and micromotor drives the oblique cam rotating head running that is installed on the motor, under rotating head and stress spring acting in conjunction, vibrating arm produces vibration, impels clinical thermometer synchronous vibration, because the stress difference at mercury slug two ends, mercury slug in the clinical thermometer flows fast towards the oscillation point vertically, reaches initial point and resets.After the power switch closure, no foreign matter blocks in the photoelectric sensor at ordinary times, and signal is arranged in the main amplifier, and the input of timing circuit no signal, timing circuit no-output driving switch pipe is not worked, not to the micromotor power supply, so not work done.After clinical thermometer inserts jack, because blocking of clinical thermometer, photosignal changes in the photoelectric sensor, and the pulse of variation is amplified through the control of amplifier, the driving switch plumber is done, the rotation of driving micromotor, the beginning work done, the drive signal of micromotor is through timing circuit, in the time of setting, close the micromotor enabling signal automatically, take out and finished the clinical thermometer that the mercury slug initial point resets, insert the clinical thermometer that another needs reset again, work repeatedly successively.Insert when clinical thermometer and to get when surpassing 5 minutes interval time, the power supply automatic shutdown circuitry in the main circuit starts, and closes main circuit, to preserve the energy content of battery.

The utility model has the advantages that: external form is small and exquisite attractive in appearance, can block to hang on the pocket, and is easy to use, safe and reliable.
