Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of sphygmomanometer.
Background technique
Sphygmomanometer is a kind of instrument that can measure human blood-pressure, and mercurial sphygmomanometer is one kind of sphygmomanometer.Using mercury
When blood pressure measuring is taken blood pressure, mercurial sphygmomanometer includes cuff, rubber ball, rubber tube, valve, mercury calibration gauge and several portions of shell
Point, mercury calibration gauge and shell are rotatablely connected, and can be stored inside the shell.The mercury pot for containing mercury is further fixed in shell,
Mercury calibration gauge includes glass tube and the graduation apparatus positioned at glass tube two sides, and mercury pot is connected to glass tube, is set at the top of glass tube
There is an exhaust outlet, in measurement process, when inflating into cuff, the mercury in mercury pot enters in glass tube, can by scale value
To read the height of mercury in glass tube, measurement result is obtained.
Be equipped with mercury switch on mercury pot with the connectivity part of glass tube, after closing mercury switch, mercury in mercury pot without
Method enters in glass tube.Measure front opening mercury switch after, the mercury in mercury pot enters in glass tube, and on graduation apparatus
Zero graduation is concordant, and after measurement, the mercury in glass tube falls to zero graduation position again, is turning off the switch top rake blood pressure
The mercury of meter, glass bottom of the tube flows into mercury pot.But often there is user to forget that closing mercury switchs in actual use,
Mercury remains in glass bottom of the tube, and last mercury can be revealed from exhaust outlet.
After mercury leakage, mercurial sphygmomanometer can not accurately measure the blood pressure of human body again, and mercury is toxic, mild in Standard Gases
Under air pressure, mercury formation mercury oxide easy to oxidize, mercury oxide, which is formed, is easy the little particle that is sucked by human body, and the toxicity of mercury oxide
It is larger, endanger the life security of people.
Summary of the invention
The purpose of the present invention is to provide a kind of anti-leak mercurial sphygmomanometers for preventing mercury from revealing.
In order to achieve the above objectives, the technical scheme is that anti-leak mercurial sphygmomanometer, including containing box and along vertical
Direction is glued to the mounting plate of storage chamber interior wall, is fixed with glass tube, link block and mercury pot, the glass on the mounting plate
Pipe top is equipped with exhaust outlet, the link block is located at below glass tube, equipped with glass tube to be connected to mercury pot in link block
Interface channel is fixed at intervals with the first brush and the second brush in the interface channel, and the first electricity is fixed in the link block
Magnet and the second electromagnet connecting with the second brush, the containing box side wall are equipped with the switch of openable first electromagnet；Institute
Interface channel side wall is stated equipped with enclosed slot, the enclosed slot is interior to be equipped with closing spring and can slide along enclosed slot and can close connection
The closing block in channel, the closing both ends of the spring be separately fixed at closing groove sidewall and closing block on, first electromagnet and
Second electromagnet can attract closing block and closing block is made to open interface channel；
The containing box side wall, which is fixed with piston rod, can be mounted the cylinder that plate is pressed, and be equipped with both ends in cylinder and fix respectively
Reset spring in cylinder end wall and cylinder piston；The containing box be fixed with far from mounting plate side be connected to cylinder plus
Pressure cylinder, it is described pressurization cylinder in equipped with support spring and can along pressurization cylinder sliding pressurizing block, the support spring both ends respectively with

Gas enter in glass tube, increase the pressure in glass tube, remaining mercury enters mercury in glass tube and interface channel
In pot, effectively mercury is avoided to reveal.
(2) first brushes are connected to extraneous power supply, and mercury is metal, when mercury is electric with the first brush and second simultaneously
When brush contact, the circuit between the first point brush, the second brush and the second electromagnet is in connected state, and the energization of the second electromagnet is opened
Beginning work, closing block by the second electromagnet magneticaction and slide into enclosed slot, closing block open interface channel, glass tube
It can flow into mercury pot with the mercury in interface channel without the blocking by closing block.After mercury flows into mercury pot,
First brush and the second brush disconnect, and the second electromagnet stops working, and closing block is no longer influenced by the magneticaction of the second electromagnet,
Closing block closes interface channel, and the mercury in mercury pot is avoided to flow out, and further avoids mercury leakage.
(3) in use, manually pressing switch, the first electromagnet is started to work, and closing block is made in the magnetic force of the first electromagnet
With in lower slide-in enclosed slot, interface channel is opened, and the mercury in mercury pot can be flowed into smoothly in glass tube, mercury simultaneously with
First brush and the second brush contact, the second electromagnet are started to work, and the second electromagnet makes closing block one to the magnetic force of closing block
It directly rests in enclosed slot, guarantees that measurement can be normally carried out.
Preferred embodiment one, as the further improvement to base case, glass tube is fixedly connected with link block, the connection
Block is fixedly connected with mercury pot.Do not have between glass tube and link block and between link block and mercury pot gap, further to keep away
Exempt from mercury to reveal from gap.
Preferred embodiment two is equipped with torsional spring as the further improvement to base case between containing box side wall and mounting plate,
The mounting plate is glued far from mercury pot side a hook, and the containing box is fixed on the outer wall far from mounting plate side can be with
Link up with the link of cooperation.Mounting plate can be made to be located in containing box by the cooperation of hook and link, hook is separated with link
Afterwards, mounting plate is produced out of containing box automatically under the effect of torsion spring, does not need manual rotation, and use is more convenient.
Preferred embodiment three, as the further improvement to base case, interface channel is connected to mercury bottom of the pot portion.Mercury pot
The junction of upper interface channel and mercury pot is lower, can also enter glass by interface channel when the mercury in mercury pot is less
In pipe, the dosage of mercury is reduced.
Preferred embodiment four, as the further improvement to preferred embodiment three, the first brush and the second brush are respectively positioned on closing
Between block and mercury pot.After not having mercury simultaneously with the first brush and the second brush contact, the second electromagnet can just stop work
Make, closing block closes interface channel, guarantees in the interface channel between closing block and glass tube the water without mercury, in mercury pot
Silver can not cross closing block and enter glass tube, further avoid revealing after mercury enters glass tube from exhaust outlet.
