Abstract
The utility model discloses a drip speed controller for transfusion, which is characterized in that the drip speed controller has a photoelectric sensor arranged outside a transfusion drip tube, wherein the photoelectric sensor is connected with a signal receiving and processing circuit which is connected with a power supply circuit. The utility model has the advantages that the drip speed controller has novel structure, advanced design, high sensitivity, stable operation, small volume and low energy consumption; the drip speed controller enhances the safety of transfusion and lightens patients' mental burden and nursing staffs' labor intensity.
Description
Technical field:
This utility model relates to Medical Technology, is a kind of auxiliary device of patient infusion that is, specifically, is a kind of transfusion drip speed modulator.
Background technology:
In the clinical transfusion treatment, some specific drugs, cardiac disorder, old and pediatric patient must strict control transfusion drip speeds.But in real work, tend to occur drip speed and cause infusing too fast or situation such as the obstruction of finishing, infuse in transfusion is in time handled after taking place and caused serious adverse consequences owing to patient's self-regulated.Therefore dispute often also takes place with medical institutions in patient, has also increased many troubles to nursery work.
Summary of the invention:
The purpose of this utility model provides a kind of highly sensitive, and working stability has strengthened the safety of transfusion greatly, has alleviated patients ' psychological burden and nursing staff's labor intensity, and volume is little, and low transfusion drip speed modulator consumes energy.
Technical solution of the present utility model is: a kind of transfusion drip speed modulator is characterized in that: have to be loaded on the outer photoelectric sensor of transfusion drip tube, photoelectric sensor is accepted to be connected with treatment circuit with signal, and signal acceptance is connected with power circuit with treatment circuit.
A light-emitting tube is arranged in the photoelectric sensor described in this utility model, and corresponding with it light receiving tube, lens are housed before light receiving tube.In signal acceptance and the treatment circuit central processing unit is arranged, central processing unit is connected with the signals collecting amplification treatment circuit, and is connected to keyboard to set up circuit and signal output apparatus.Signal output apparatus can be radio transmitter, and corresponding with it wireless receiving circuit is arranged, and wireless receiving circuit is connected to display circuit.
The beneficial effects of the utility model are: novel structure, advanced design, highly sensitive, working stability has strengthened the safety of transfusion greatly, alleviated psychological burden and the nursing staff labor intensity repeatedly maked an inspection tour of patient in infusion process, further obviously reduced the generation of doctor-patient dispute, simultaneously high in technological content, volume is little, it is low to consume energy, and is convenient to promote the use of.
Below in conjunction with drawings and Examples this utility model is further described:
Description of drawings:
Fig. 1 is the structural representation of a kind of transfusion drip speed modulator of the present utility model;
Fig. 2 is that the signal in the transfusion drip speed modulator of the present utility model is accepted and the treatment circuit circuit diagram.
The specific embodiment:
Fig. 1, Fig. 2 have described an embodiment of the present utility model jointly, in this embodiment, the photoelectric sensor that is loaded on outside the transfusion drip tube 4 are arranged, and photoelectric sensor is accepted to be connected with treatment circuit 6 with signal, and signal is accepted to be connected with power circuit with treatment circuit 6.A light-emitting tube 1 is arranged in the described photoelectric sensor, and corresponding with it light receiving tube 3, lens 2 are housed before light receiving tube 3.In signal acceptance and the treatment circuit 6 central processing unit 21 is arranged, central processing unit 21 is connected with signals collecting amplification treatment circuit 22, and is connected to keyboard to set up circuit 23 and signal output apparatus.Signal output apparatus can be radio transmitter 24, and corresponding with it wireless receiving circuit 25 is arranged, and wireless receiving circuit 25 is connected to display circuit 26.It is the infraluminescence pipe of 9400A that photoelectric sensor can adopt luminescence peak.
Can add warning circuit in this utility model, and in time send alarm signal according to the warning bound of setting.Of the present utility model circuit can adopt common central processing unit circuit and corresponding accessory circuit, do not repeat them here.
Photoelectric sensor of the present utility model can adopt the infraluminescence pipe, and the infraluminescence pipe is made up of the PN junction of GaAS, and luminescence peak is 9400A, is in outside the visible light wave, can significantly reduce the interference of visible light.The response speed of GaAS diode is tens nanoseconds of orders of magnitude, uses the response speed that can obtain the rise time and be about 2 μ s fall time with phototransistor combination.Up-to-date embedded microcomputer chip is adopted in the core, system clock up to 12MHz owing to used above-mentioned device, therefore whole device can be done very small and exquisitely, reliable, the very faint conversion of signals that not only pick off can be brought is reliable control signal, and the while can calculate current fast, the flow of dripping, and warning bound and the actual speed of dripping can be set, and in case occur to drip speed too fast, cross slow or stop, all can send alarm signal, launched to nurse station, pointed out corresponding warning bed label in central control system.Power pack can adopt ready-made inlet switch power supply, and is fool proof reliable.
Using method: instrument uses easy and simple to handle, only needs photoelectric sensor is clipped on the transfusion drip tube, sets at display screen and drips fast warning bound, and device promptly enters the early warning monitoring state automatically.
