[Prior Art] [0002] In order to maintain good health, it is important to pay attention to the state of blood pressure. Therefore, sphygmomanometers that have only been seen in hospitals have been continually reducing volume, weight, and cost, and maintaining measurement accuracy, so that sphygmomanometers can be purchased in general households to monitor family health. [0003] It can be seen from the published "Respiratory Blood Pressure Measurement Device" of the Republic of China Patent Certificate No. 1322004 that such a portable sphygmomanometer has a fluid bag with a fluid expansion and contraction, and is internally disposed to expand the fluid bag. a body casing of the contracted expansion and contraction mechanism, a flexible connecting tube connecting the fluid bag and the expansion and contraction mechanism, and the connecting tube pulled out from the body casing is pulled into a connection disposed inside the body Holding the pull-in mechanism of the accommodating department _. As can be seen from Fig. 5 of the foregoing, the barometer has an air system for blood pressure measurement, which includes the above-described expansion and contraction mechanism and a pressure sensor. Further, the blood pressure is measured, and the sphygmomanometer further has an operation unit, a power supply unit, a CPU, an oscillating circuit, a pump drive circuit, a valve drive circuit, and the like, and the plurality of circuits control the expansion and contraction mechanism, and the expansion and contraction mechanism A gas is supplied to fill the aforementioned fluid bag to tighten the human body. The expansion and contraction mechanism is then allowed to gradually vent the gas in the fluid bag. The pressure sensor senses the pressure difference of the human body when the fluid bag is pressurized or released. [0004] However, whether the pressure measured by the pressure sensor is accurate depends on whether the pressure change of the aforementioned fluid bag is stable. The aforementioned pressure changes include 10021905# single number A0101 3rd true/common 16 pages 1013064104-0 M427914 101. February 20th revised replacement page human body blood pressure and inflation/exhaust airflow pressure changes, so accurate To measure the blood pressure of the human body, it is necessary to ensure that the inflation/discharge amount is stable. [0005] Please refer to the Republic of China Patent Certificate No. M292360 "Structure with stable pressure relief in the pressure device of a sphygmomanometer", which discloses a blood pressure device having a pulse sensor and a connection connecting the pulse sensor The tube is connected to a valve body through a joint, and the other side of the valve body is connected to a pressurized body for supplying gas. The valve body has an air passage, and the two ends of the air passage are respectively connected to the pressing body and the joint, and a connecting tube is further connected to the air passage. A passage body is provided on the passage of the communication pipe, and the plug body is made of a multi-air through hole material. The aforementioned sphygmomanometer gradually releases air through the plurality of air passage holes on the plug body to achieve the purpose of pressure relief. However, in the process, it is difficult to control the size of the plurality of air through holes of the plug body, and one side of the plug body is directly in contact with the outside air, and dirt or dust easily blocks the air through holes, resulting in a gradual decrease in measurement accuracy. And the short service life, resulting in sphygmomanometer can not accurately detect human blood and pressure. [New content] [0006] Based on the problems arising from the aforementioned pre-conventions, the purpose of this case is to improve the conventional problems of unstable sphygmomanometer gas flow and reduce accuracy. [0007] This case is to improve the airflow stability.

The main air flow duct is provided with an air flow buffering element, and the air flow buffering element comprises a gas flow in the main air flow duct. The air flow is 10021905^^^ A〇101. Page 4 / Total 16 pages 1013064104-0 M427914 .101.02.20 The airflow outlet through which the replacement page passes is corrected. The airflow outlet has a diameter of between 0. lram and 0. 5 ram, so that the airflow in the main airflow conduit passes through the airflow outlet before flowing to the pressure sensing unit. [0008] After the airflow cushioning component is added, the airflow outlet is closer to the pressure sensing component, and the airflow outlet has a small diameter and a fixed diameter, so that the airflow outlet is measured by the pressure sensing component. The gas pressure reached is relatively stable. By stabilizing the airflow pressure generated by the sphygmomanometer itself, the detected human blood pressure can be more accurate. Moreover, the airflow buffering element is located in the main airflow duct, which is not easy to be damaged or blocked by dust, and thus has a service life superior to that of the conventional structure. [f application method] [0009] This case is a sphygmomanometer for improving the stability of airflow. The technical features of the present invention will be described below in conjunction with the drawings. [0010] Please refer to FIG. 1. FIG. 1 discloses the main mechanical structure inside a sphygmomanometer 100. The sphygmomanometer 100 has an air pump 1, a main air flow duct 3 that leads the air output by the air pump 1, a main air flow path 6 that communicates with the main air flow duct 3, and a communication line with the main air flow duct 3. The pressure sensing unit 2 can be a static capacitance sensor or a semiconductor sensor. As can be seen in the specific aspect shown in FIG. 1, the main air flow duct 3 includes a pump air supply line 31 and a pressure communication tube 32, and the pump air supply line 31 is connected to the air pump; the pressure communication tube 32 is connected to the pressure. Sensing unit 2. The air pump 1 generates an air flow after being triggered by the user, and the air flow generated by the air pump 1 is output through the main air flow duct 3 through the main air flow passage 6. The main air flow passage 6 is configured to communicate with a bladder (not shown) that is tightly connected to the human torso. When the air pump 1 provides airflow, the airflow is provided by the 1013064104-010021905^^'^ A〇101^5 1 / ^ 16 1 M427914 101. On the 20th of February, when the shuttle is replacing the main airflow passage 6 output, the airbag tightens the human trunk, thereby obtaining the pressure of the human blood vessel to react to the internal air through the airbag. The air bag communicates with the main air flow duct 3 through the main air flow passage 6, so that the pressure fluctuation in the air bag also affects the pressure in the main air flow duct 3. The pressure sensing unit 2 communicates with the main air flow conduit 3 through the pressure communication tube 32, and thus the blood pressure of the human blood vessel reaction to the airbag is measured by the pressure difference in the main air flow conduit 3. More specifically, the main air flow duct 3 is divided into a leak pipe 33, and one end of the air leakage pipe 33 is connected to a leak valve 4 having a small gas flow. After the airbag is tightened to the human torso, the air in the airbag can be slowly vented through the air leakage valve 4. The pressure sensing unit 2 can be set to detect the main airflow conduit when the air leakage valve 4 is slowly deflated. The blood pressure is measured by the change of pressure within 3. Further, in order to accelerate the air flowing out of the air bag, the main air flow duct 3 may branch out a deflation pipe 34, and one end of the bleed pipe is connected to a bleed valve 5 having a large gas flow. After the pressure sensing unit 2 has measured the blood pressure value, the air in the airbag can be quickly released by the large gas flow of the vent valve 5. [0011] Please refer to FIG. 1, FIG. 2 and FIG. 3 together. In order to improve the accuracy of the pressure sensing unit 2 to detect pressure, it is necessary to stabilize the airflow in the space directly communicating with the pressure sensing unit 2. 1 毫米之间。 The airflow venting port 7 has a diameter of 0. 1 mm, the airflow venting member 7 is provided with a gas flow venting member. Between 0 and 5 mm, the airflow in the main airflow duct 3 passes through the airflow outlet 72 before flowing to the pressure sensing unit 2. It should be noted that the airflow buffering component 7 of the present invention is connected to the main airflow duct 3 for convenient fitting. The airflow buffering component 7 may of course further include an airflow buffer space 70, and a communication with the airflow buffer space 70.

As can be seen in the first embodiment shown in FIG. 1, the air flow cushioning element 7 can be mounted in the pump air supply line 31, and the air flow inlet 71 is directed toward the air pump 1 such that the main air flow duct 3 The airflow is first collected in the airflow buffer space 70 through the airflow inlet 71, and then flows through the airflow outlet 72 to the pressure sensing unit 2. Through such a design, the high-pressure airflow outputted by the air pump 1 will be filled into the airflow buffer space 70 through the airflow inlet 71, and further enter the main airflow conduit 3 through the airflow outlet 72 having a small diameter to communicate through the pressure. The tube 3 2 is in communication with the pressure sensing unit 2. Since the air outlet 72 has a small diameter, the air flow rate through the air outlet 72 is stable, and the pressure fluctuation is small, so that the air pressure fluctuation caused by the machine is minimized, and the human body sensed by the pressure sensing unit 2 Blood pressure accuracy increases. Referring to FIG. 4, the airflow buffering member 7 may also be located in the pressure communication tube 32, so that the airflow in the main airflow conduit 3 needs to be first collected in the airflow buffer space 7.0 through the airflow inlet 71, and then It flows through the air outlet 72 to the pressure sensing unit 2. Therefore, when the air pump 1 output gas is injected into the main air flow duct 3, it is required to pass through the air flow buffering member 7 in the pressure communication tube 32 to be measured by the pressure sensing unit 2. As described in the foregoing paragraph, the air outlet 7 2 has a small aperture, so that the air flow through the air outlet 7 is stable, and the pressure variation is small, so that the pressure variation caused by the machine is minimized, and the pressure sensing unit 2 The accuracy of the measured blood pressure of the human body increases. 100219(^单职除1第7页/16 pages 1013064104-0 M427914 [0013] 101.
