Abstract
The utility model relates to a woundless anesthesia plane measuring apparatus, which comprises an outer shell and a probe exposed out of the outer shell. The utility model is characterized in that the outer shell is inside provided with an electronic circuit composed of an oscillator, a voltage amplifying device, a power amplifying device and a power supply, wherein, the output of the oscillator is connected with the voltage amplifying device, the output of the voltage amplifying device is connected with the power amplifying device, the output of the power amplifying device is connected with the probe, and a modulator is also arranged in front of the oscillator. The voltage amplifying device adopts a precise direct current amplifier with low power which is inside provided with a compensator, and the power amplifying device adopts an amplifying circuit which has coil coupling and complementation.
Description
Technical field
This utility model relates to medical electronics, is used to check the noinvasive level of anesthesia determinator of patient's anaesthetic effect before particularly a kind of clinical operation.
Background technology
Spinal anesthesia clinically, cervical plexus anesthesia, brachial plexus anesthesial etc. often need to measure level of anesthesia, thereby instruct the local anaesthetics consumption and prevent that level of anesthesia is too high or too low.Present domestic hospital all uses disposable syringe syringe needle acupuncture patient skin, and according to patient pain is felt to judge level of anesthesia and effect.Because syringe needle is very sharp, nearly all patient can stay some pinpricks at body surface, brings misery and has stayed the hidden danger that infects to patient.If because of medical personnel's carelessness or irresponsibility, use exhausted syringe needle that patient is carried out acupuncture manipulation, then previous patient is if suffer from blood source transmissible disease, and as hepatitis, AIDS etc., this brings great danger will for back one patient.In addition, sharp syringe needle also has the probability of accidentally injuring medical personnel.
Summary of the invention
The purpose of this utility model is the generation of stopping above-mentioned danger, designed a kind of noinvasive level of anesthesia determinator, used the effect of the probe replacement syringe needle of determinator, probe does not penetrate body surface, but can make patient that the obvious impression of irriate is arranged, above-mentioned purpose is realized by following technical proposals:
Noinvasive level of anesthesia determinator, include shell and expose the probe of shell, it is characterized in that being provided with in the shell and contain the electronic circuit that agitator, voltage amplification, power amplification power supply are formed, agitator output connects voltage amplification, voltage amplification output connects power amplification, and power amplification output connects probe.Also be provided with manipulator before the agitator.Establish the low-power precision DC amplifier of compensator in voltage amplification is adopted, power amplification adopts the coil coupling to add complementary amplifying circuit.
Advantage of the present utility model and effect:
(1) determinator probe output HIGH voltage, little current impulse act on human body, and patient can not be subjected to wound when feeling that safety shocks by electricity, safety, reliable.
(2) patient and medical personnel no longer have the danger of cross infection, and patient and medical personnel also no longer have mental burden in the operation, and operating effect is good.
Description of drawings
Fig. 1 is this utility model circuit block diagram;
Fig. 2 is this utility model electrical schematic diagram;
Fig. 3 is this utility model product entity figure.
The specific embodiment
Because producing the electronic circuit of high pressure, little electric current is mature technology, be applied in the prior art products quite a few, as electric billy, electric mosquito-fly-swatter etc., all be to use this type of circuit output action to be hit object, so the application no longer add narration to the principle and the formation of circuit in quilt.Fig. 1 and Fig. 2 have provided a kind of enforcement circuit, agitator adopts the NE555 integrated package, the characteristics of this pierce circuit are that its oscillator frequency is the linear function of control voltage, adjust input voltage, can be linear corresponding different frequencies of oscillation with it, the parameter that changes manipulator can make its dutycycle and control frequently change progression and change.Voltage amplifier adopts low-power precision DC amplifier, and Internal compensator has avoided because the use difficulty that external compensation brings.Factors such as the power inverter design considers that the resistance of human body surface differs, and output probe A (electrode) rest is inaccurate require to have the power output of adjusting in a big way, adopt the coil coupling to add complementary this problem that solved preferably of amplifying.Power supply is for adapting to agitator, and manipulator, voltage amplification, the different service voltage requirement of power amplification change from 1-8V, and must have high-accuracy output and capacity of resisting disturbance.In addition, also internal protection circuitry can be set for preventing owing to high pressure damages transistor in the circuit, holding circuit starts and transistorized range of safety operation adapts.The desirable 9V battery of determinator is as power supply, and about output 1W, voltage 0-300V is adjustable, and electric current 0-1mA is adjustable, and pulse width 0-100 μ S is adjustable, exportable pulse or series impulse, and triggering mode is manual.Among Fig. 3, the 1st, determinator shell, the 2nd, on and off switch, the 3rd, adjusting knob, the output intensity that is used for regulating electrode (probe) A.
Claims (3)
1. noinvasive level of anesthesia determinator, include shell and expose the probe of shell, it is characterized in that being provided with in the shell and contain the electronic circuit that agitator, voltage amplification, power amplification, power supply are formed, agitator output connects voltage amplification, voltage amplification output connects power amplification, and power amplification output connects probe.
2. noinvasive level of anesthesia determinator according to claim 1 is characterized in that also being provided with manipulator before the agitator.
3. noinvasive level of anesthesia determinator according to claim 1 and 2 is characterized in that voltage amplification establishes the low-power precision DC amplifier of compensator in adopting, and power amplification adopts the coil coupling to add complementary amplifying circuit.
