In this way, gas is directly over intake channel and enters inside equipment when the inflation of gas charge and discharge device.When deflation then
Directly it is discharged to outside shell by the access that loses heart.During entire inflation/deflation, gas will not with gas charge and discharge device, air bag and
Component contact except corresponding access, thus can guarantee other component will not with the liquid water or moisture entrained by gas,
And then reduce the impaired possibility of these components.
Please refer to Fig. 1 and 2, in a kind of embodiment, which includes shell C, gas charge and discharge device, sensor
The components such as S and air bag AB.Shell C can be the shell of Wrist blood pressure meter, is also possible to watch style electronic sphygmomanometer or has
The watchcase of the watch style vital signs patient monitor of blood pressure measuring function.Wherein, which includes air pump P and control of losing heart
Product.The intake channel is connected to air pump P, and air pump P also has gas outlet, which is connected to air bag.The access that loses heart
On discouraged control piece, which is connected to air bag.
In a kind of embodiment, which can be used solenoid valve SV or other kinds of valve.Shell C tool
There is the confined space Ci of water-proof function.Air pump P, solenoid valve SV and sensor S are set within confined space Ci.Air pump
There is P air inlet Pa and gas outlet Pb, solenoid valve SV there is air inlet Sa and leakage port Sb, closed shell C to have
Air inlet Ca, aperture Cb and bleeder port Cc.
And confined space the air inlet Pa of air pump P is directly docked and connected by the air inlet Ca of intake channel and shell C, i.e.,
Atmosphere except Ci.The gas outlet Sb of solenoid valve SV is directly docked by losing heart access with the bleeder port Cc of shell C
Connection, i.e., with the atmosphere except confined space Ci.The gas outlet Pb of air pump P, the air inlet Sa of solenoid valve SV and biography
Sensor S is interconnected, then is connected to by the gas nozzle Aa of the open C b and air bag AB of shell C.Confined space Ci keeps air-tightness.
The blood pressure measurement device of the present embodiment start measurement when, as shown in Figure 1, solenoid valve SV closure, air pump P into
Port Pa (direction b100) sucks the atmosphere (direction a100) of shell exterior, to cuff or air bag AB pressurization inflation (side after compression
To c100).After measurement, as shown in Fig. 2, inside air pump P stopping movement, solenoid valve SV opening, cuff or air bag AB
Flow of the compressed gas to shell C (direction d100), then flow to the air inlet Sa (direction e100) of solenoid valve SV, it is last outward
(direction f100) releases outside shell C.
During entire inflation/deflation, which is directly over intake channel from the outside of shell C and enters inside equipment.
It is then directly discharged to outside shell by the access that loses heart when deflation, gas will not be with gas charge and discharge device, air bag and corresponding access
Except component contact, and then reduce liquid water or steam entrained by gas to the impaired possibility of these components.
In this embodiment, which includes air inlet and bleeder port.Intake channel is docked with the sealing of the air inlet of shell
Or it is stretched out out of shell air inlet.The access that loses heart is docked with the sealing of the bleeder port of shell or is stretched out out of shell bleeder port.
Certainly, in other embodiments, can also be collected at one with the other end of intake channel and discouraged access, and with it is outer
The same port sealing of shell is docked or is stretched out out of same stomata of the shell.That is, being equivalent to the same stomata both conducts
Air inlet is also used as bleeder port.
In the present embodiment, sensor S is connected in the gas circuit between air pump P and air bag AB, to connect with air bag AB
It is logical, for measuring the air pressure of air bag AB.In other embodiments, sensor S can be directly connected to air bag AB.
Further, 1 and 2 are please referred to, in a kind of embodiment, air pump P and pressure release control piece (such as solenoid valve
So) it is divided into two-way setting.That is, can be considered air pump P and pressure release control piece for two independent components, which is connected to
Between the gas outlet and air bag AB of air pump P.
Certainly, in other embodiments, can also air pump P and discouraged control piece pass through respectively corresponding gas channels with
Air bag AB connection.
Further, in a kind of variant embodiment, gas charge and discharge device is integrated air pump.The integrated air pump includes air inlet
Access, the pressurization part for inflation, gas fill port, lose heart access and the pressure release control unit for control of losing heart.Intake channel with

Air bag connection, pressure release control unit are connected to discouraged access.Pressure release control unit control the logical of leakage port closes.
Fig. 3 and 4 are please referred to, specifically, in a kind of embodiment, the integrated air pump IP is instead of air pump P and solenoid valve
SV.The integrated other components such as air pump IP and sensor S are set within confined space Ci.
Integrated air pump IP has air inlet IPa, gas outlet IPb and a leakage port IPc, closed shell C have air inlet Ca,
Aperture Cb and bleeder port Cc.
The air inlet Ca of the air inlet IPa and shell C of integrated air pump IP are connected to by intake channel, i.e., with confined space Ci
Except atmosphere.The gas outlet IPb of integrated air pump IP is connected to sensor S, then passes through the aperture Cb and air bag AB of shell C
Gas nozzle Aa connection.The bleeder port Cc of the leakage port IPc and shell C of integrated air pump IP are connected to by discouraged access, i.e., with it is closed
Atmosphere except the Ci of space.
When the blood pressure measurement device of the present embodiment starts measurement, as shown in figure 3, leakage port IPc closure, integrated air pump IP warp
The atmosphere (direction a100) for crossing air inlet IPa (direction b100) sucking shell exterior fills cuff or air bag AB pressurization after compression
Gas (direction c100).After measurement, as shown in figure 4, integrated air pump IP stops the leakage port of compression motion, integrated air pump IP
Compressed gas inside IPc opening, cuff or air bag AB flows to integrated air pump IP (direction d100), using (the side leakage port IPc
It releases to e100) to the outside of shell C.
The integrated air pump IP integrates air pump and discouraged control piece for Fig. 1 and 2 illustrated embodiment,
Structure is more compact, more conducively the miniaturization of blood pressure measurement device.
Further, in a kind of embodiment, which is directly connected to discouraged access, i.e., gas fill port is led to discouraged
The same open communication of Lu Keyu air bag, isolates gas fill port and discouraged access again later.Certainly, in other embodiments,
The gas fill port and discouraged access can also be independently arranged, and be connected to respectively with air bag.
Further, Figures 5 and 6 are please referred to, in a kind of embodiment, the direct communicated air bags AB of sensor S.
