Description

Multi-functional automatic drawing out and infusion device

The utility model relates to a kind of medical apparatus, particularly a kind of multi-functional automatic drawing out and infusion device.

Utilization is manually had an injection, blood drawing or intravenous injection be by manually carrying out, and wastes time and energy, and working efficiency is not high.Chinese patent CN2109859U has introduced a kind of pump formula automatic transfusion device, it by liquid bag, pump chamber, pipeline, connect into pipe-line system, control by intergrated circuit, miniature straight driven by motor tertiary gear promotes lever compressing pump chamber, it is defeated automatically to control realization outward by pipeline, can be at regular time and quantity with various soups input human bodies.This kind transfusion device is real and showed automatic infusion, and its liquid injects and depends on pump, can only be as transfusion, and function singleness, and can not disposablely use.

The purpose of this utility model is to provide a kind of energy automatically quantitative extracting bodily fluid or injectable drug, and is disposable multi-functional automatic drawing out and infusion device.

The multi-functional automatic drawing out and infusion device of the utility model is to realize like this, it comprises the casing of being made up of base and case lid, be installed on the base and the motor that is connected with controller, the gear that is connected with motor shaft, with gear matched and be installed on the tooth bar that is fixed on the base rail, cooperate with the tooth bar two ends respectively, and be installed on the quantitative calibrated scale, and can be along fixed upper limit switch and the limit switch of quantitative calibrated scale slip, quantitatively scale is fixed on the base, fastens syringe on base, the piston that cooperates with syringe by syringe, the end of piston is fastened on tooth bar by piston, and with the injection needles of syringe nipple releasable connection.Wherein, injection needles by with the flexible needle tubing of syringe nipple releasable connection, the joint that an end is connected with needle tubing, the syringe needle that is connected with the joint the other end.Its middle controller can be separate part, also can be directly installed on the base, and rotating speed of motor and forward and backward are controlled by controller.

The working principle of the multi-functional automatic drawing out and infusion device of the utility model is, injection needles is connected on the syringe nipple, slip upper limit switch, and be fixed on the quantitative calibrated scale certain position, controller switches stirred, the motor counter-rotating, gear plectrum carry-over bar on the motor shaft moves right, and drives piston when tooth bar moves to right and moves to right, thereby finish extracting bodily fluid, when tooth bar moved to right to upper limit switch, upper limit switch rotated the motor stop; Otherwise, stir controller switches, motor just changes, and the gear plectrum carry-over bar on the motor shaft is moved to the left, and drives piston when tooth bar moves to left and moves to left, thereby finish injection work, and when tooth bar moved to left to limit switch, limit switch was rotated the motor stop.The regulative mode of upper and lower limit switch is, fixing limit switch, and slip upper limit switch can quantitatively be taken out, annotate to the position of requirement; Slip upper limit switch is to the summation position that needs the multiple injection amount, and the limit switch of sliding again can be carried out multiple injection to per injection amount position.

The advantage of the multi-functional automatic drawing out and infusion device of the utility model is rational in infrastructure, easy to use, simple to operate, reliable performance, and accurate measurement is the medical apparatus of clinical each section's indispensability, is particularly suitable for large quantities of health check-ups blood drawing and work such as intravenous injection when giving emergency treatment to a patient.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing.

Fig. 4: controller circuitry connection diagram

The multi-functional automatic drawing out and infusion device of the utility model comprises by base 1 and case benefit 2 casings of forming, be installed on the base 1 and the motor 3 that is connected with controller 20, the gear 5 that is connected with motor shaft 4, cooperate with gear 5 and be installed on tooth bar 7 on the guide rail 6 that is fixed on base 1, cooperate with tooth bar 7 two ends respectively, and be installed on the quantitative calibrated scale 9, and can be along fixed upper limit switch 10 and the limit switch 8 of quantitative calibrated scale 9 slips, quantitatively scale 9 is fixed on the base 1, be fixed on syringe 12 on the base 1 by syringe card 11, the piston 13 that cooperates with syringe 12, the end of piston 13 is fixed on the tooth bar 7 by piston card 14, with the injection needles 16 of syringe nipple 15 releasable connections, and be installed in controller 20 on the base.Wherein, the joint 18 that injection needles 16 is connected with needle tubing 17 by flexible needle tubing 17, one ends with the releasable connection of syringe nipple, the syringe needle 19 that is connected with joint 18 the other ends is formed.

The electric machine controller circuit is by transformer B, bridge rectifier D 1～D4, filter capacitor C1～C2, resistance R 1～R2, pressure regulation potentiometer RP1～RP2, adjustable voltage stabilizer IC, storage battery E, power switch K1～K2, reverser K3, limit switch K5, upper limit K switch 4, switch starter AN, and protective tube RD constitutes.Its annexation is, connect respectively and connect the 220V Ac behind K1 and the RD in the elementary two ends of B, secondary D1～the D4 that connects imports, D1～D4 output connects C1, R2, C2, K2, K3 one end respectively, another termination C1 the other end and IC one end, the D5 positive pole connects the IC output terminal, negative pole connects the IC input end, the IC output terminal connects the anodal and C2 the other end of D6 respectively, the series connection of D6 negative pole RP2, E connect the K2 the other end, connect the K3 input end simultaneously, and the K3 output terminal connects K4 and K5 one end respectively, another termination motor two ends of K4 and K5 are connected to AN between K4 and K5.R2, RP1 and R1 are the peripheral circuit of IC, meet IC behind the R2 the other end series connection RP1, and the R1 two ends are connected to the middle-end that is connected of IC and RP1, D6 respectively.Working principle is, the 220V Ac is depressurized to about 40V through transformer, through D1～D4 rectification, and C1 filtering, the IC voltage stabilizing through C2 filtering once more, promptly obtains the 24V galvanic current and presses, and is added to the direct current generator two ends through K3, K4, K5 again, and motor rotates; As changing its direction of motor rotation, only need press K2 and get final product; As changing motor speed, only need to regulate RP1, RP2.But AC/DC.
