This air valve 100 also comprises elastomer 109, and this elastomer 109 is arranged on dividing plate 20, and this air inlet valve chamber, dividing plate 20 and elastomer 109 form check valve 102.Its median septum 20 is equivalent to valve seat, and elastomer 109 is equivalent to valve body.When the air pressure of the first valve chamber 26 is greater than the second valve chamber 23, elastomer 109 deformation under pressure differential effect, thus be communicated with the first valve chamber 26 and the second valve chamber 23.

Particularly, in the present embodiment one, 109 one-tenth, elastomer umbrella.This umbrella elastomer 109 comprises bar portion (bar portion can be elastomeric material, also can be non-elastic material) and has elastic umbrella portion, and elastic umbrella portion can be that EP rubbers or silicone rubber elastomeric material are made.Its king-rod portion is inserted on dividing plate 20, and by carrying out spacing from the position of bar portion outwardly convex.This umbrella portion is positioned at the second valve chamber 23, and dividing plate 20 is provided with at least one main passage 22, and main passage 22 is arranged in overlay area, umbrella portion.This umbrella portion can deformation under the pressure differential effect of the first valve chamber 26 and the second valve chamber 23, is opened and closed by main passage 22.

In the above-described embodiment, although the elastomer 109 that have employed umbrella is used as the valve body of check valve 102, in implementation process, also can adopt the elastomer of other shape that main passage 22 can be sealed, such as mushroom-shaped etc.

Please refer to Fig. 1,2,4, air bleeding valve indoor are provided with elastic ventable diaphragm 108, and ventable diaphragm 108 can be that EP rubbers or silicone rubber elastomeric material are made.

Aerofluxus valve chamber is divided into the 3rd valve chamber 36 and the 4th valve chamber 33 by this ventable diaphragm 108.3rd valve chamber 36 is provided with the second air inlet the 37, four valve chamber 33 and is provided with air vent 32 and the second connector 34.And corresponding second connector 34 of ventable diaphragm 108 and/or air vent 32 arrange formation air bleeding valve 103.

When the air pressure in the 3rd valve chamber 36 is greater than the air pressure in the 4th valve chamber 33, ventable diaphragm 108 deformation covers the second connector 34 and/or air vent 32.When the air pressure in the 3rd valve chamber 36 is less than or equal to the air pressure in the 4th valve chamber 33, ventable diaphragm 108 restores opens the second connector 34 and/or air vent 32, and gas in the 4th valve chamber 33 is discharged fast by air vent 32.

In this example, air vent 32 is set to a protruding valve seat 30, and wherein ventable diaphragm 108 covers this valve seat 30 under distortion, as shown in Figure 5.

In this example, this first valve chamber 26 and the 3rd valve chamber 36 form the first space, and the second valve chamber 23 and the 4th valve chamber 33 form second space.

Please refer to Fig. 1-3, the present embodiment is also provided with blow vent 28 between the first valve chamber 26 and the second valve chamber 23, and particularly, this blow vent 28 is arranged on dividing plate.This blow vent 28 can provide required air-flow to pass through, and when gas pressurized unit pressurizes, passage 28 can make to form certain pressure differential between the first valve chamber 26 and the second valve chamber 23, the enough closed ventable diaphragm 108 between 3rd valve chamber 36 and the 4th valve chamber 33 of this pressure differential, and open the elastomer 109 between the first valve chamber 26 and the second valve chamber 23.As can be seen here, the ventilation flow rate of passage is less than the charge flow rate of the first air inlet 24.To this, the uninterrupted that those skilled in the art can provide according to gas pressurized unit, is realized by adjustment passage 28 and the relative size of the first air inlet 24, relative populations and length.

Please continue to refer to Fig. 1 and 2, lid 106 is formed with the valve 106A that is communicated with the wrist strap rubber tube 110A of cuff the airbag 110 and lid air vent 106B for being discharged by the air of cuff airbag 110.By the valve 106A that the wrist strap rubber tube 110A of cuff airbag 110 is arranged on lid 106, air valve 100 is connected with cuff airbag 110.

Substrate 107 is formed substrate air inlet 107A.To be communicated with the substrate air inlet 107A of substrate 107 by the connector 101A of air pump 101 and air valve 100 is connected with air pump 101.

In above structure, air valve 100 makes air pump 101 pressurize when starting the mensuration of blood pressure.By this, gas sucks from substrate air inlet 107A by air valve 100.In addition, gas is delivered to cuff airbag 110 via check valve 102 by air valve 100, to improve the air pressure in cuff airbag 110.Then, after the mensuration of blood pressure terminates, air pump 101 stops pressurization, and the air of cuff airbag 110 is discharged from lid air vent 106B rapidly via the second connector 34 and air vent 32.

Please refer to Fig. 5, air valve 100 makes air pump 101 carry out compression motion when starting the mensuration of blood pressure.Air pump 101 makes air flow in the first valve chamber 26 from the tap 101A of air pump 101, because the ventilation of blow vent 28 to give the pressurization flow of the first valve chamber 26 much smaller than air pump 101, in check valve 102, produce the discharge pressure along forward (with the first valve chamber be just to the second valve chamber direction) from the first air inlet 24 towards the first connector 27 because of the compression motion of air pump 101, the pressure of pressure ratio second valve chamber 23 of the first valve chamber 26 is high.By this, make limit, elastomer 109 umbrella portion prolong tilting, main passage 22 is opened.

Meanwhile, in air bleeding valve 103, because of the compression motion of air pump 101, the pressure of the 3rd valve chamber 36 is raised, high with the pressure of pressure ratio the 4th valve chamber 33 making the 3rd valve chamber 36.By this, ventable diaphragm 108 pairs of air vents 32 seal (in other embodiments, may be the second connector 34 by what seal, or the second connector 34 and air vent 32 be sealed simultaneously), so that the ventilation of the second connector 34 and air vent 32 is blocked.Consequently, air is transported to cuff airbag 110 (as shown in Figure 5) from air pump 101 via the first air inlet 24 of check valve 102 and main passage 22, thus improves the air pressure in cuff airbag 110.

By this, the air flowed out from main passage 22 via the first air inlet 24 of check valve 102 is the pressure lower than the discharge pressure of air pump 101.On the other hand, the first valve chamber 26 is applied with the discharge pressure of air pump 101.Consequently, in check valve 102, the pressure of pressure ratio second valve chamber 23 of the first valve chamber 26 is larger, to maintain the state opened by elastomer 109 in check valve 102.

In addition, the structure that is communicated with of the second connector 34 of air valve 100 the first connector 27 and air bleeding valve 103 that are formed as check valve 102.The gas flowing into the 4th valve chamber 33 from the second connector 34 is smaller than the pressure in the 3rd valve chamber 36, to maintain the state of being closed by ventable diaphragm 108 in air bleeding valve 103.Because the pressure differential of the 3rd valve chamber 36 and the 4th valve chamber 33 is very little, therefore, this pressure differential can't extremely offset, thus ventable diaphragm 108 can be prevented damaged.

Please refer to Fig. 1 and 6, after the mensuration of blood pressure terminates, air valve 100 stops the compression motion of air pump 101.At this, very little compared with the volume of the air that the first valve chamber 26 can be accommodated with cuff airbag 110 with the volume of the 3rd valve chamber 36.Therefore, after the compression motion of air pump 101 stops, the first valve chamber 26 is communicated with by blow vent 28 with the second valve chamber 23.Consequently, in air valve 100, the pressure of the first valve chamber 26 becomes rapidly identical with the pressure of the second valve chamber 23.

In air valve 100, once the pressure of the first valve chamber 26 becomes identical with the pressure of the second valve chamber 23, then ventable diaphragm 108 resets at once and the second connector 34 and/or air vent 32 to be opened, then the 3rd valve chamber 33 is in the state be in communication with the outside, the air of cuff airbag 110, via air vent 32, is discharged (as shown in Figure 6) rapidly from lid air vent 106B.

Compressed air, by air pump 101, air valve 100 being connected with cuff airbag 110, just can being filled in cuff airbag 110, and air can being discharged rapidly from cuff airbag 110 by the present embodiment one.In addition, for any air pump (comprising the air pump that gas circuit resistance is very large), without the need to arranging very difficult integrated extra " vent valve ", therefore air valve 100 shown in the present embodiment be a kind of low cost of manufacture, power consumption little, be suitable for microminiaturized air valve.

In the above-described embodiment, although be formed on the periphery of air vent 32 by the valve seat 30 of air bleeding valve 103, in implementation process, also valve seat 30 can be formed in the periphery of the second connector 34.

In the above-described embodiment, although the second connector 34 is connected with cuff airbag 110 by air bleeding valve 103, and air vent 32 is connected with lid air vent 106B, but in implementation process, also under the second connector 34 can being configured at the position of air vent 32 shown in Fig. 1, be connected with cuff airbag 110, and under air vent 32 being configured at the position of the second connector 34 shown in Fig. 1, and be connected with lid air vent 106B.
