Abstract
The utility model discloses an electrical pressure making device which is used for sphygmomanometer non-mercury certified meter. The utility model has the advantages of high speed of pressure making, stabilization and accuracy, which can regulate and fix the values of pressure output. The existing pressing rubber ball of sphygmomanometer (instrument) can be superseded by the electric pressure making device. The electric pressure making device and the sphygmomanometer (instrument) together measure the blood pressure of human body. The utility model can also be used in industrial and mining establishments as a low pressure instrument. The non-mercury certified meter electric pressure making device for sphygmomanometer adopts an electric motor to drive an eccentric cam, a crank and a rubber diaphragm to start reciprocal motion in order to make pressure. The air is sent into the non-mercury certified meter for sphygmomanometer after the air passes through an air intake check valve, a low pressure air chamber, a gas discharge nozzle, a high pressure chamber and a pressure value regulating delivery outlet in order to test the sphygmomanometer (instrument).
Description
This utility model relates to a kind of electronic pressure making device that is applied to the Compressed Gas of sphygomanometer mercury-free calibrator, and it is fast that it makes pressure speed, and constant value control output pressure value is accurately stable, can also be the supporting measurement human blood-pressure of sphygomanometer.
Present known sphygomanometer mercury-free calibrator adopts outer air supply source or ball to make pressure, it is to be cut down by preceding gas, non-return cuts down, ball, back gas cuts down composition, the space air is cut down by back gas and enters the rubber air chamber in the hand ball change ball when using, compress after non-return cuts down, preceding gas cuts down and enters the sphygomanometer mercury-free calibrator as examining and determine sphygomanometer (table) with source of the gas or as sphygomanometer (table), source of the gas is measured human blood-pressure, this pressure mode of making, and the pulsed pressurization often causes spray hydrargyrum, superpressure is damaged sphygomanometer and sphygomanometer standard, has brought difficulty for calibrating sphygomanometer (table).Brought difficulty also for the measurement human blood-pressure.
The purpose of this utility model provides a kind of electronic pressure making device, replaces original pressure device of manually making, and can be that sphygomanometer mercury-free calibrator and sphygomanometer standard sphygomanometer (table) are supporting easily, and can be applicable to industry and mining and do the low-pressure signal source and use.It is fast that it makes pressure speed, and constant value control output pressure value is accurately stable.
The purpose of this utility model is to realize like this, the electronic pressure making device of sphygomanometer mercury-free calibrator, motor is arranged, eccentric, crank, axle sleeve, driving shaft, the air inlet non-return cuts down, rubber diaphragm, loam cake, low-pressure chamber, exhaust nozzle, pressure magnitude are regulated following of delivery outlet pressure making device, seals volume, base plate, plenum chamber, the non-return rubber diaphragm, fixedly rubber diaphragm is formed with pallet.Make when pressing and at first power, motor rotates, air cuts down through air inlet air inlet non-return, rubber diaphragm goes out the non-return nozzle after entering low-pressure chamber's compression, the non-return diaphragm enters plenum chamber, Compressed Gas output is regulated the sphygomanometer that delivery outlet is connected with electronic pressure making device by pressure magnitude, the mercury-free calibrator connection, examine and determine sphygomanometer (table) or with the supporting instead of rubber ball of sphygomanometer (table), measure human blood-pressure, reach the electronic purpose that the compression set value is regulated the output pressure value of making.
Owing to adopt such scheme, the electronic pressure of making of energy when measuring human blood-pressure and calibrating sphygomanometer (table), constant value control output pressure value is accurately stable, is particularly useful for examining and determine sphygomanometer (table) work and does the use of high-precision pressure signal source, can satisfy the needs of vertification regulation fully.
