Abstract
The utility model relates to an over pressure protector for a sphygmomanometer, which mainly solves the problem that the user continues using the sphygmomanometer when over pressure of the sphygmomanometer occurs because the over pressure of the sphygmomanometer is not easily perceived. The over pressure protector for a sphygmomanometer, which is characterized in that a by-pass tube is communicated with an air source passage of the sphygmomanometer, and that an electromagnetic valve is connected to the by-pass tube of the air source, is mainly used for over pressure protection of mercury reduction of the sphygmomanometer to limit over pressure use.
Description
This utility model relates to the overproof protection instrument of a kind of sphygomanometer.
At present, sphygomanometer is legal strong inspection measurement instrument, and in use, the leakage because of hydrargyrum often reduces, and surpasses the legal franchise of metering, and pressure value and the actual blood pressure measured differ greatly, and user is difficult for discovering and continue use.Directly have influence on quality of medical care and patient's life security.
The purpose of this utility model provides the overproof protection instrument of a kind of sphygomanometer, and overproof sphygomanometer is directly limited use, and also warning prompt user sphygomanometer is overproof, plays the pressure supervisory role.
This utility model is the improvement to the overproof caution supervision of sphygomanometer instrument, on the basis of the overproof caution supervision of sphygomanometer instrument, increases bypass pipe and communicates with sphygomanometer source of the gas passage, increases pilot-type solenoid valve and is connected on the bypass pipe.Sphygomanometer is when normal the use, and because of electrode contact with hydrargyrum, the A amplifier in is high potential and conducting, driving closed electromagnetic valve source of the gas bypass pipe, and the while relay indicating light is bright.This moment, the B amplifier ended.When sphygomanometer was overproof because of hydrargyrum reduces, electrode did not contact with hydrargyrum, and the A amplifier in is that zero potential is ended, and electromagnetic valve is not worked, and the sphygomanometer bypass pipe communicates with atmosphere, and it can't be pressurizeed, and has directly limited use.Because ending of A amplifier worked to indicate and extinguished, and the B amplifier in is high potential and conducting, drives alarm equipment alarm, the indication of reporting to the police is bright simultaneously.Warning prompt user sphygomanometer is overproof, maintenance calibrating in time.
This utility model can limit the use of overproof sphygomanometer effectively, and the power consumptive province, and volume is little, is convenient to install and use in sphygomanometer.
Introduce this utility model in detail below in conjunction with accompanying drawing, wherein:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is circuit theory diagrams of the present utility model.
Know that by Fig. 1,2 this overproof protection instrument is reported to the police by power supply (1) switch (2) electrode (3) A amplifier (4) B amplifier (5) electromagnetic valve (6) work indication (7) and indicated (8) alarm (9) to form.Power supply (1) adopts battery three joints No. 2, and switch (2) adopts microswitch, and links with sphygomanometer mercury valve (11), and electrode (3) adopts silver electrode, is fixed in the sphygomanometer indicating value pipe (12), and its termination is positioned at gauge under the zero-bit franchise; Electromagnetic valve (6) adopts type pilot, is connected on the bypass pipe (13), and bypass pipe (13) communicates with source of the gas (10) passage.When sphygomanometer normally uses, open the normal closure of making war of mercury valve (11) switch (2), enter duty simultaneously.At this moment, electrode (3) contacts with hydrargyrum, and A amplifier (4) input is high potential and conducting, and driving work indication (7) is bright, and sphygomanometer bypass pipe (13) is closed in electromagnetic valve (6) adhesive, and sphygomanometer can normally use.When sphygomanometer hydrargyrum reduces when overproof, electrode (3) does not contact with hydrargyrum, A amplifier (4) input electronegative potential and ending, work indication (7) is extinguished, not adhesive of electromagnetic valve, and sphygomanometer bypass pipe (13) communicates with atmospheric pressure, source of the gas (10) can't be pressurizeed, and sphygomanometer also just can't use.While, B amplifier (5) input was high potential and conducting owing to A amplifier (4) ends, and drove alarm (9) and reported to the police, and reported to the police and indicated (8) bright, warned user of service's sphygomanometer overproof.
Claims (2)
1, the overproof protection instrument of a kind of sphygomanometer comprises power supply, switch, amplifier, indicator, alarm, electrode, electromagnetic valve composition, it is characterized in that bypass pipe communicates with sphygomanometer source of the gas passage, and electromagnetic valve is installed on the bypass pipe of sphygomanometer source of the gas.
2, the overproof protection instrument of sphygomanometer according to claim 1 is characterized in that electromagnetic valve adopts pilot-type solenoid valve.
