Whether within a preset range to set pressure value that 1 detection sphygmomanometer A, B, C to be measured are fed back respectively.
Then, as above, successively in the static pressure standard pressure of 50mmhg, 100mmhg, 150mmhg, 200mmhg, 250mmhg
The static pressure performance that measuring blood pressure meter A, B, C are treated under power is tested.Herein it should be noted that sphygmomanometer A, B, C to be measured can
It is tested simultaneously under the same static criteria pressure.
Herein it is understood that in step S2, the execution order of multiple static pressure normal pressures is not limited to by 0
It is successively increased to 250mmhg, it is above-mentioned to be only illustrated as a preferred embodiment.On the basis for not influencing other test steps
On, allow there are other execution orders.
Preset range in step S2 is arranged according to specific needs.For example, in a specific embodiment, described is pre-
If range is ± 2mmhg.Such as, under the static criteria pressure of 50mmhg, if the value that sphygmomanometer A measurement to be measured obtains is greater than
52mmhg then determines that sphygmomanometer A to be measured is unqualified, then can show " ERR1 " on display screen 15.

Preferably, the value of airtightness criteria pressure is multiple, the air-tightness more comprehensively, accurately to treat in terms of measuring blood pressure 9
It is tested.The quantity and specific value of airtightness criteria pressure are set according to the type of sphygmomanometer 9 to be measured, with more comprehensively
And the can detect pressure range for dispersedly covering sphygmomanometer 9 to be measured is advisable.For example, in a specific embodiment, it is multiple airtight
The value of normal pressure is respectively 250mmhg, 150mmhg and 50mmhg.
It should be noted that the pressure value of the three airtightness criteria pressure selected here includes in above-mentioned steps S2
In the pressure value of static pressure normal pressure, above-mentioned " comprehensively and dispersion " principle was not only met, but also normal pressure can be reduced
The number of device, and then reduce the cost of air pressure comparison device 2.It in other embodiments, can be with only a part of airtightness criteria pressure
The pressure value of power includes in the pressure value of the static pressure normal pressure in above-mentioned steps S2.
Specifically, incorporated by reference to shown in Fig. 1, in step S3, master control set 1 is by communication interface 94 simultaneously to be measured
Sphygmomanometer A, B, C issue the instruction of " enter air tightness test ", sphygmomanometer A, B, C to be measured receive enter after the instruction it is corresponding
Then program returns to the message of " having entered air tightness test " to master control set 1.
Firstly, being tested under first airtightness criteria pressure: 1 control pressure of master control set comparison device 2 provides one
The pressure of a 250mmhg gives sphygmomanometer A, B, C to be measured, and master control set 1 controls solenoid valve a, b, c and is turned off at this time, in this state
Lower holding certain time, the respective pressure sensor 93 of sphygmomanometer A, B, C to be measured are continuously detected pressure value during this period of time
And multiple pressure value is fed back into master control set 1, master control set 1 detects the minimal pressure that each sphygmomanometer 9 to be measured is fed back
Within a preset range whether force value.
Then, after guaranteeing that sphygmomanometer A, B to be measured, C, the pressure in test gas circuit 4 all release, master control set 1 controls gas
Pressure comparison device 2 provides 150mmhg, to the air-tightness of three sphygmomanometer A, B, C to be measured under the airtightness criteria pressure of 150mmhg
It is tested.And so on, finally complete the test under the airtightness criteria pressure of 50mmhg.
Similarly, herein it is understood that the execution order of multiple static pressure normal pressures is simultaneously unlimited in step S3
It is successively reduced in by 250mmhg, it is above-mentioned to be only illustrated as a preferred embodiment.Do not influencing other test steps
On the basis of, allow there are other execution orders.
Retention time in step S3 is arranged according to specific needs.For example, in a specific embodiment, described guarantor
Holding the time can be more than or equal to 8s, more specifically, can be 10s.
Preset range in step S3 is arranged according to specific needs.For example, in a specific embodiment, described is pre-
If range is 2mmhg.Such as, under the pressure of 50mmhg, if the minimal pressure force value that sphygmomanometer A measurement to be measured obtains is less than
48mmhg then determines that sphygmomanometer A to be measured is unqualified.
Finally, master control set 1 stores the minimal pressure force value that sphygmomanometer A, B, C to be measured are returned, and its corresponding model, number
Etc. data save jointly.
It should be noted that, step S2 and S3 are not limited to execute according to sequence as above, that is, are not limited to three herein
Sphygmomanometer 9 to be measured is completed to carry out air tightness test to three sphygmomanometers 9 to be measured again after whole static pressure tests.Due to above
The value of used airtightness criteria pressure and the value of static pressure normal pressure, which have, at least partly to be repeated, duplicate for each
Value, then a sphygmomanometer 9 to be measured can first be completed static pressure test and then based on static pressure normal pressure at this time into
Row air tightness test.
For example, first carrying out the static state of sphygmomanometer A, B, C to be measured simultaneously in the pressure of 0mmhg for sphygmomanometer A, B, C to be measured
Pressure test；Then the static pressure test that sphygmomanometer A, B, C to be measured are completed at the same time at 50mmgh continues if qualified at this
10s is kept to be completed at the same time the test of the air-tightness of sphygmomanometer A, B, C to be measured under the pressure of 50mmgh.Subsequently, 100mmhg's
Pressure carries out the static pressure test of sphygmomanometer A, B, C to be measured simultaneously；Then be completed at the same time at 150mmgh sphygmomanometer A, B to be measured,
The static pressure of C is tested, if qualified, continues to keep 10s to be completed at the same time sphygmomanometer A, B, C to be measured under the pressure of the 150mmgh
Air-tightness test ..., intersect and carry out.In this way, being not necessarily to multiple switching standards pressure generator, energy is reduced
Consumption, equipment loss, while also improving detection efficiency.
The above calibration, static pressure test and air tightness test are steps mostly important in sphygmomanometer factory testing process.
In addition, comprehensively being tested to further treat measuring blood pressure meter 9, the blood pressure measuring method for testing of the present embodiment further includes following
Step:
Step S4, the limit press ann test: master control set 1 controls the inflator pump 92 that sphygmomanometer 9 to be measured starts its own, directly
It is more than alarming value to the blowing pressure.If sphygmomanometer 9 to be measured is alarmed at this time, determine that the sphygmomanometer 9 to be measured is qualified, if to be measured at this time
Sphygmomanometer 9 is not alarmed, then determines that the sphygmomanometer 9 to be measured is unqualified.
Specifically, incorporated by reference to shown in Fig. 1, in step S4, firstly, master control set 1 is by communication interface 94 to blood to be measured
Pressure meter 9 issues the instruction of " enter the limit and press ann test ", and sphygmomanometer 9 to be measured enters corresponding program after receiving the instruction, so
Backward master control set 1 returns to the message of " having entered limit pressure ann test ".
After pressure in test gas circuit 4 all releases, master control set 1 controls solenoid valve g and closes, and master control set 1 controls gas
Pressure comparison device 2 provides the pressure of 0mmgh to sphygmomanometer A to be measured, and master control set 1, which controls solenoid valve f, to be opened and (or says and keep beating
Open), control solenoid valve e is closed.Then, master control set 1 controls sphygmomanometer A to be measured and starts its inflator pump 92, and inflator pump 92 is inflated
The high pressure of generation maintains between the air container 61 of sphygmomanometer A and 200cc to be measured.The pressure sensing of sphygmomanometer A to be measured itself
The pressure value is simultaneously fed back to master control set 1 by 93 real-time detection of device pressure at this time.Until pressure value meets and exceeds alarming value.
Then, according to above-mentioned steps, then the test of another sphygmomanometer B to be measured is carried out.Herein it should be noted that, in the step
In rapid S4, multiple sphygmomanometer A, B, C to be measured are successively to test, that is, when sphygmomanometer A to be measured is tested, in addition to measuring blood pressure
Meter B, C corresponding solenoid valve b, c are turned off.After measuring blood pressure A completes the test, control solenoid valve g is opened and will be tested gas
Pressure on road 4 all releases, and then controls solenoid valve a and closes and control solenoid valve b opening, sphygmomanometer B to be measured starts it and fills
Air pump 92 starts to boost.
Accordingly, master control set 1 can be to issue to three sphygmomanometers 9 to be measured simultaneously by each communication interface 94 and " enter
The instruction of limit pressure ann test " is also possible to issue by several times, repeat no more.
The specific value of alarming value is designed according to the type of sphygmomanometer 9 to be measured, is usually chosen and is slightly smaller than the type
Sphygmomanometer to be measured 9 the maximum pressure that can bear of cuff.For example, in a specific embodiment, which is
296mmgh.When pressure value is greater than 296mmgh, sphygmomanometer 9 to be measured should alarm, otherwise as unqualified.In this way, can avoid
Pressure excessive in actual use damages cuff.
Preferably, being with pressure value detected by the pressure sensor 93 of sphygmomanometer A to be measured itself in step S4
With reference to.The alarm form of sphygmomanometer 9 to be measured can be the control chip (not shown) by itself on the screen of its own
Show that an alarm signal e.g. can be " ERR7 ".Meanwhile main control module 11 reads sphygmomanometer 9 to be measured and detects it and controls core
Whether piece gives alarm signal.
Step S5, pressure release test, by detecting the relieving characteristics of sphygmomanometer 9 to be measured: treating 9 offer first based on measuring blood pressure
High pressure opens the valve 91 of sphygmomanometer 9 to be measured, until pressure reduction to the first low pressure, detects sphygmomanometer 9 to be measured by the first high pressure
To the time used in the first low pressure, the time used in the pressure release determines that sphygmomanometer 9 to be measured is qualified if within a preset range；If it is not,
Then determine that sphygmomanometer 9 to be measured is unqualified.
Preferably, the step executes after step s4, due to producing in test gas circuit 4 in step s 4
High pressure (alarming value) directly can carry out pressure release using the high pressure.Certainly, since sphygmomanometer A, B, C to be measured multiple in step S4 are
It successively tests, step S5 is to execute after being next to step S4 for the same sphygmomanometer 9 to be measured.With reference to above-mentioned step S2 and
The intersection of step S3.
Specifically, after step S4, " enter firstly, master control set 1 is issued by communication interface 94 to sphygmomanometer 9 to be measured
The instruction of pressure release test ", sphygmomanometer to be measured, which receives, enters corresponding program after the instruction, then return to master control set 1 " into
Enter pressure release test " message.
Gas circuit control module 12 controls solenoid valve a, b, c and closes.The valve 91 that master control set 1 controls sphygmomanometer A to be measured is beaten
Start pressure release after opening, which reduces since 296mmgh, 93 real-time detection of pressure sensor of sphygmomanometer A to be measured itself
The pressure value is simultaneously transferred to main control module 11 by its internal pressure value.When the pressure sensor 93 of sphygmomanometer A to be measured itself is examined
When the pressure value measured is reduced to the first high pressure, main control module 11 starts timing, until pressure value is reduced to the second high pressure, master control
Module 11 calculates from the first high pressure relief to first and compresses the time used, if the time used in pressure release is within a preset range,
Determine that sphygmomanometer A to be measured is qualified；If it is not, then determining that sphygmomanometer A to be measured is unqualified.
Then, the valve 91 that gas circuit control module 12 controls sphygmomanometer B itself to be measured is opened, similarly, in sphygmomanometer B to be measured
The pressure value is simultaneously transferred to main control module 11 by its internal pressure value of 93 real-time detection of pressure sensor in portion.
Subsequently, the pressure release test for executing sphygmomanometer C to be measured, repeats no more.
Accordingly, in step S5, master control set 1 can be issued to multiple sphygmomanometers 9 to be measured simultaneously " to be entered pressure release to survey
The instruction of examination " is also possible to issue by several times.
Finally, master control set 1 time used in those first high pressures, the first low pressure, pressure release is corresponded to it is each to measuring blood pressure
The data such as the model and number of meter 9 are saved.
The numerical value of first high pressure and the first low pressure is selected based on the principle of proximity sensing value and 0.In step S5
Preset range specifically the type of its valve 91 and is set based on security requirement according to the type of sphygmomanometer 9 to be measured.
For example, in a specific embodiment, the first high pressure can be chosen in the range of 260 ± 10mmgh, and the first low pressure can
To be chosen in the range of 15 ± 10mmmgh.More specifically, the first high pressure can be 260mmgh, the first low pressure be can be
15mmgh.On this basis, preset range described in step S5 can be less than or equal to 4s.

Device 1 controls solenoid valve g closing and solenoid valve a, e are opened.The inflator pump 92 that master control set 1 controls sphygmomanometer A to be measured starts
Work, and master control set 1 reads pressure value measured by the pressure sensor 93 of sphygmomanometer A to be measured itself in real time.Master control dress
It sets 1 calculating sphygmomanometer A to be measured and the time used in second high pressure is increased to as the second low pressure.
The specific value of second high pressure and the second low pressure is also specifically arranged according to the type of sphygmomanometer 9 to be measured.For example,
In one embodiment, for boost type sphygmomanometer, the second low pressure can be 0, or other numerical value slightly larger than 0, the
Two high pressures are 44mmgh~54mmgh.The pressurization time used is set on the basis of the numerical value of the first high pressure and the second high pressure
It is fixed.In a specific embodiment, the second low pressure is 0, and the second high pressure is 54mmgh, the time used of pressurizeing be less than or equal to
34s.If sphygmomanometer A to be measured is unqualified, then it represents that its inflator pump 92 is unqualified.For buck sphygmomanometer, when being no more than
When can boost to 300mmgh in the time of 10s, then it can determine that as qualification.
Then, after guaranteeing that the pressure in sphygmomanometer 9 to be measured, test gas circuit 4 and caisson 6 all releases, electromagnetism is controlled
Valve g is closed, and master control set 1 controls solenoid valve b, e opening again, and ibid step, carries out the applied voltage test of sphygmomanometer B to be measured.Successively
