Description
Technical field
The present invention relates to a kind of crossover sub, more particularly to a kind of electronic sphygmomanometer static pressure measurement special joint, belongs to
In product quality detection field.
Background technology
With the development of economy and society, living standards of the people increasingly improve, health becomes hot spot of concern.
Medical instrument of the sphygmomanometer as measurement human bloodstream pressure, in being widely used in clinical diagnosis and treating.Sphygmomanometer measures
Value it is accurate whether, be directly related to the health and life security of people, therefore sphygmomanometer is listed in state compulsion and examines and determine
Measurement instrument, using unit or it is personal every year will gauge check department examine and determine requisition cycle.
In recent years, for electronic sphygmomanometer because of no mercury pollution, easy to operate, measurement is convenient and efficient, gradual substitution mercury blood pressure
Meter becomes the main tool of blood pressure measurement.Static pressure is one most important performance indicator of electronic sphygmomanometer, is pressed fixed
The detection of power stability inferior, the sensitivity of key reaction electronic sphygmomanometer internal pressure sensor and accuracy.Metering inspection at present
Survey department is according to JJG692-2010《Noninvasive automatic measuring sphygmomanometer》Vertification regulation requirement, static state is being carried out to electronic sphygmomanometer
During pressure calibration, there is a problem.Although electronic sphygmomanometer is set to static pressure test pattern, standard pressure gauge is used
（There is pressurization function）Appropriate pressure value is selected to carry out static pressure pressurization to electronic sphygmomanometer, still, under some pressure,
Sphygmomanometer static pressure show value can not keep stable, trace it to its cause mainly sphygmomanometer work when, external gas source or built-in
Air pressure caused by inflation motor has two components inside sphygmomanometer and is exhausted, and one is electronic control quick air releasing
Valve, one is automatic steam leak-off valve 22 at a slow speed.Fig. 5 is the theory structure schematic diagram of arm belt electronic sphygmomanometer.Including arm belt electricity
Sub- sphygmomanometer main body 20, is respectively arranged with inflation motor intercommunicating pore 21a, at a slow speed steam leak-off valve intercommunicating pore in electronic sphygmomanometer main body 20
22a, pressure sensor intercommunicating pore 23a, quick release valve intercommunicating pore 24a, arm band intercommunicating pore 25a, connect on five intercommunicating pores respectively
It is connected to inflation motor 21, steam leak-off valve 22, pressure sensor 23, quick release valve 24 and arm band 25, inflation motor 21 are used at a slow speed
Pressurize to 20 inner inflatable of electronic sphygmomanometer main body, steam leak-off valve 22 is gradually to discharge internal gas for detecting blood pressure at a slow speed
High pressure and locations of low pressure, for the exhaust at a slow speed in the course of work；Pressure sensor 23 is by inside electronic sphygmomanometer main body 20
Digital signal is converted into after pressure detecting, is shown on digital display 26, quick release valve 24 is used for after measuring or surveys
Pressure is not in due course during amount, the valve of Quick air-discharge；Arm band 25 is connected with electronic sphygmomanometer main body 20, is mainly bundled in
The detection blood pressure on arm is detected, steam leak-off valve 22 belongs to mechanical valve at a slow speed, is not electronic proportioning valve, from electronic control, in blood
In pressure meter work process, closure state is not at, can be lost heart always, and speed of losing heart is determined according to pressure size.It is if quiet
State pressure measurement indicating value can not keep stable, also can not just realize the measurement of static pressure.Conventional calibration method is dismounting blood pressure
Shell is counted, pulls up the conduit at a slow speed on steam leak-off valve 22, static pressure calibrating, operating process ten are carried out with clamp closure gas circuit
Point cumbersome, complicated, labor intensity is very big, make use of sealant to be sealed in an assembling process moreover, some products are close, warp
The product after dismounting is crossed, the original-pack precision and air-tightness of product are difficult to ensure that after reduction, certain be stranded is brought to quality testing
How difficulty, in the case of dismounting as few as possible carry out quality testing, one faced in the detection process for being sphygmomanometer
Problem.
The content of the invention
It can not keep stablizing, it is necessary to spend for sphygmomanometer static pressure show value in existing electronic sphygmomanometer detection process
Very big strength and some time carry out the problem of dismounting sphygmomanometer shell is detected, is then reduced again, and the present invention provides
A kind of electronic sphygmomanometer static measurement special joint, its purpose is to remove dismounting shell from, reduces the installation of electronic sphygmomanometer,
It can ensure sphygmomanometer not because of detection and quality is affected, it is ensured that the original-pack air-tightness of product, it is possible to increase electronic sphygmomanometer
Detection speed, testing result can be accurately obtained as early as possible.
The technical scheme is that：A kind of electronic sphygmomanometer static pressure measures special joint, and the special joint is
Hollow tubular structure, including the insertion section being connected as a single entity and operation portion, special joint substitute former arm band plug and are inserted into insertion section
In electronic sphygmomanometer main body, gap is equipped between insertion section outside diameter and electronic sphygmomanometer inner major diameter, insertion section periphery is provided with
