Abstract
The utility model discloses a kind of fast self-regulation transfusion device, comprise infusion bottle, tube for transfusion tubule, tube for transfusion extra heavy pipe, single-chip microcomputer, motor, pressure transducer and buzzer; Test pulse by pressure transducer, by single-chip microcomputer, data are processed, make logical judgment and then control step motor to change dripping speed or controlling buzzer warning of transfusion device.Compared to existing infusion alarm, the advantage of this infusion alarm is under the condition utilizing little device and achieves more function, adds and changes droplet fast function, the too fast warning function of pulse with pulse.
Description
Technical field
This utility model relates to medical instruments field, specifically a kind of fast self-regulation transfusion device.
Background technology
In modern medical service, patient because the reason of transfusion causes pulse and rapid heart rate, thus can produce discomfort, at this moment preferably can change dripping speed and sending warning of transfusion.
The outer existing transfusion device of Now Domestic is by the tube for transfusion between dropping funnel with syringe needle being connected transfusion actuator, single-chip microcomputer is connected successively with driver, motor, the output shaft of motor is connected by screw with transfusion actuator, and being formed with single-chip microcomputer is the closed-loop control system of core.Between the fixation clip that tube for transfusion is placed on transfusion actuator and movable pressing board, the external screw thread of motor axle sleeve end engages with the female thread of movable pressing board, motor rotates and movable pressing board can be driven be elevated, controls to drip speed thus reach in the object of alarm of being near completion of infusing tube for transfusion extruding.
Transfusion device now automatically can only detect and drip speed, then remain on certain numerical value dripping speed instead of automatically change a speed based on a certain parameter: infrared transmitter and receptor are equipped with in the dropping funnel place of existing transfusion device, it is fast that infrared transmitter and receptor can detect dripping of drop, is connected with single-chip microcomputer by holding wire.Single-chip microcomputer processes data, if it is different with predetermined speed of dripping to drip speed, single-chip microcomputer can send signal controling stepping motor and rotate and makes to drip speed and remain on rated value, and can not along with the change of pulse automatically regulate drip fast.Application number be 201310067532.2 application for a patent for invention disclose a kind of transfusion device, this transfusion device comprises and drips fast induction apparatus, flow control valve and a single-chip microcomputer, drip fast induction apparatus for detect drip kettle drip speed, and by information transmission to single-chip microcomputer; Single-chip microcomputer receives information, and controls flow control valve according to the comparing result of information and preset value, can not change transfusion speed, do not have the change solved along with pulse automatically to regulate the problem of dripping speed according to the change of pulse constantly of patient infusion.
Summary of the invention
For the deficiencies in the prior art, the technical problem that quasi-solution of the present invention is determined is, provides a kind of and drips fast self-regulation transfusion device, comprise infusion bottle, tube for transfusion tubule, tube for transfusion extra heavy pipe, single-chip microcomputer, motor, pressure transducer and buzzer; Test pulse by pressure transducer, by single-chip microcomputer, data are processed, make logical judgment and then control step motor to change dripping speed or controlling buzzer warning of transfusion device.Compared to existing infusion alarm, the advantage of this infusion alarm is under the condition utilizing little device and achieves more function, adds and changes droplet fast function, the too fast warning function of pulse with pulse.
The technical scheme that the present invention solve the technical problem is, provides a kind of and drips fast self-regulation transfusion device, comprise infusion bottle, tube for transfusion tubule, tube for transfusion extra heavy pipe, single-chip microcomputer, motor, pressure transducer and buzzer; Described infusion bottle, tube for transfusion tubule are connected successively with tube for transfusion extra heavy pipe; It is characterized in that described single-chip microcomputer, motor and buzzer are arranged on tube for transfusion extra heavy pipe, described single-chip microcomputer is electrically connected with motor, pressure transducer and buzzer respectively; A port ground connection of described pressure transducer, another port is connected with single-chip microcomputer; A port ground connection of described motor, another port is connected with single-chip microcomputer; A port ground connection of described buzzer, another port is connected with the colelctor electrode of audion, and the emitter stage of audion meets VCC, and the base stage of audion is connected with single-chip microcomputer through resistance.
The present invention's beneficial effect is compared with prior art: adopt pressure transducer, by single-chip microcomputer pulse signal processed thus reach transfusion drip speed and adjust with pulse change, pulse crosses the function of reporting to the police, and the principle simple possible of this application of installation, advantage of lower cost.
