The air inlet hole 111 and the air outlet hole 112 are located on the same side of the first straight strip 11; an air flow channel is formed between the air inlet hole 111 and the air outlet hole 112 along the long side direction of the air passage portion 10; the air passage portion 10 protrudes with air blocking blocks 17 in multiple directions in the air flow channel, and the multiple air blocking blocks 17 form an air flow buffer zone; an air pump portion 20, connected to the air inlet hole 111, for inputting gas into the air flow channel; an air valve portion 30, whose volume is smaller than that of the air pump portion 20, is connected to the air outlet hole 112, for discharging the gas in the air flow channel.

[0043] To ensure the smoothness of the air flow in the air flow channel and improve the measurement accuracy of the pressure sensor, preferably, the air passage portion 10 protrudes with air blocking blocks 17 in multiple directions in the air flow channel.

[0044] Preferably, the airway portion 10 includes: an air cavity portion 13 provided with exhaust holes 112 thereon; a sensor cavity portion 14 connected to a sensor assembly 2; a cavity connection hole 18 provided between the air cavity portion 13 and the sensor cavity portion 14; the gas in the air flow channel flows from the air cavity portion 13 through the cavity connection hole 18 to the sensor cavity portion 14, and the gas in the sensor cavity portion 14 flows to the sensor assembly 2.

[0045] Preferably, a sealing ring is provided between the sensor cavity portion 14 and the sensor assembly 2 to ensure the airtightness between the sensor cavity portion 14 and the sensor assembly 2, so that the sensor assembly 2 obtains a stable pressure monitoring environment.

[0046] Preferably, an air release hole 19 and exhaust holes 112 are oppositely provided on the air cavity portion 13, and the air release hole 19 communicates with the external space of the pump valve assembly 1 and is used to discharge the gas in the air flow channel in the opposite direction of the exhaust direction of the air valve portion 30.

[0047] Figure 3 The dotted-line arrow in the figure indicates the gas flow direction in the pump valve assembly 1 during the inflation process. Figure 6 The solid-line arrow in the figure indicates the gas flow direction in the pump valve assembly 1 during the inflation process. Combining Figure 3 、 Figure 5 and Figure 6 it can be seen that when the pump valve assembly 1 is in the inflation process, the gas generated by the air pump portion 20 passes through the intake hole 111 and then flows through the air flow channels respectively formed by the first straight bar 11 and the second straight bar 12 and enters the air cavity portion 13. Then, the gas flows from the air cavity portion 13 through the cavity connection hole 18 to the sensor cavity portion 14, and the gas in the sensor cavity portion 14 flows to the sensor assembly 2 so that the sensor assembly 2 works under air pressure. For example, it measures blood pressure.

[0048] Figure 7 The solid-line arrow in the figure indicates the gas flow direction in the pump valve assembly 1 during the blood pressure measurement process. Please refer to Figure 5 and Figure 7 , when the inflation reaches a certain air pressure value, the air pump portion 20 stops inflating, and the pump valve assembly 1 enters the blood pressure measurement period. A part of the gas in the sensor cavity portion 14 flows to the sensor assembly 2, and the other part is slowly discharged at a uniform speed by the uniform air leakage valve formed by the first air leakage piece 15 and the second air leakage piece 16, so as to generate a regular pulse waveform on the measured object. At the same time, the sensor assembly 2 detects the human pulse signal at this time.

[0049] Among them, for the uniform air leakage valve formed by the first air leakage piece 15 and the second air leakage piece 16, when manufacturing the valve of the air leakage hole 19, if the air leakage piece forming the valve is too thick, when the valve is manufactured, the opening area on the air leakage piece will be too large, and the gas will flow out rapidly, resulting in uneven air leakage of the air leakage hole 19 to the air chamber part 13, thus affecting the accuracy of blood pressure measurement; if the air leakage piece forming the valve is too thin, during use, the valve is likely to loosen, affecting the reliability of the pump valve assembly 1.

[0050] Based on this, a thin sheet with a small-aperture through hole can be first attached at the air leakage hole 19, and then a thick sheet with a large-aperture through hole is attached on the thin sheet, and the large-aperture through hole is aligned with the small-aperture through hole, so that while the gas can be discharged uniformly from the small-aperture through hole, the stability of the connection of the thin sheet is improved by the way of the thick sheet fixing the thin sheet. Specifically, the air leakage hole 19 is successively covered with the first air leakage piece 15 and the second air leakage piece 16, and the second air leakage piece 16 is used to fasten the first air leakage piece 15 to the air leakage hole 19; a first air leakage hole 151 is provided on the first air leakage piece 15 opposite to the air leakage hole 19, and a second air leakage hole 161 is opened at the position covering the first air leakage hole 151 on the second air leakage piece 16, and the area of the second air leakage hole 161 is larger than that of the first air leakage hole 151, so as to form a uniform air leakage valve at the air leakage hole 19 through the first air leakage piece 15 and the second air leakage piece 16.

[0051] Among them, both the first air leakage hole 151 and the second air leakage hole 161 are formed by laser drilling technology, the thickness of the first air leakage piece 15 is less than that of the second air leakage piece 16, and the second air leakage piece can support the first air leakage piece.

[0052] Preferably, a sealing ring is sleeved on the first air leakage piece 15. It can be that a sealing ring is sleeved between the first air leakage piece 15 and the second straight bar 12, or a sealing ring is sleeved between the first air leakage piece 15 and the second air leakage piece 16, so as to achieve airtightness through the tight-fitting effect between the first air leakage piece 15 and the sealing ring, thereby realizing uniform air leakage of the air leakage hole 19.

[0053] Preferably, the air pump part 20 is a solenoid valve.

[0054] Figure 8 The solid arrows in the figure indicate the flow direction of the gas in the pump valve assembly 1 during the exhaust process. Please refer to Figure 5 and Figure 8 , after the blood pressure measurement is completed, the solenoid valve is energized and opened for exhaust and pressure relief.

[0055] Preferably, the air pump part 20 and the air valve part 30 are respectively sleeved on the air inlet hole 111 and the air outlet hole 112 to improve the convenience of assembling the air pump part 20 and the air valve part 30 onto the air passage part 10 and the stability of connecting to the air passage part 10.

[0056] Preferably, the air valve part 30 includes an air nozzle 31. At least part of the air nozzle 31 has a pagoda-shaped outer shape. The air valve part 30 passes through the exhaust hole 112, and the pagoda-shaped outer shape part is sleeved inside the air duct part 10; a sealing ring is sleeved outside the pagoda-shaped outer shape part, and the sealing ring is used to eliminate the gap between the pagoda-shaped outer shape part and the air duct part 10.

[0057] Preferably, the pump valve assembly 1 further includes an air chamber cover plate 40. The air chamber cover plate 40 covers the air duct part 10. An air outlet nozzle 41 is provided on the air chamber cover plate 40. The air outlet nozzle 41 is aligned with the air chamber part 13 and the cavity connection hole 18, and a dust-proof breathable net 42 is provided at the air outlet nozzle 41 to ensure the normal output of air flow while isolating the influence of foreign objects on the measurement accuracy.

[0058] Preferably, a glue-stop bone position 122 is provided at the edge of the air duct part 10, and the air chamber cover plate 40 covers the glue-stop bone position 122 to improve the airtightness of the pump valve assembly 1.

[0059] In the pump valve assembly 1 provided by the embodiment of the present application, by designing the air duct part 10 to be in a bent long strip shape, and the long side is bent to form a first straight strip 11 and a second straight strip 12.
