The valve 3 has a single opening 6 and has a The ring-shaped flange 7 at the inlet 8 of the connector 4 is a sealing fit. valve 3 Upon compression and then release, air will flow out of or into valve 3 accordingly. flows into.

The connector 4 (shown in FIGS. 4-6) has a bottom 1o, which is connected to the inner tube 11. It penetrates up to the outlet 12. The inlet 8 and the outlet 12 communicate through the connector 4. This allows air to circulate.

Connector 4 comprises an annular opening 13 located at inlet 8 . This opening 13 is It communicates with a pipe 19 housed in one end of the side tube 11. annular opening 13 and A one-way flap valve 9 communicates with the pipe 19 . The annular opening 13 is further is connected to the first restrictor 14, and this restraint lifter is connected to the chamber in the connector 4. It communicates with 16. Chamber 16 opens to the atmosphere.

Furthermore, the connector 4 also has a second opening 17, in which the l'' portion opens to the atmosphere. It communicates with the second restrictor 15 leading to the chamber 16. The second one-way valve 18 is Preventing air from moving from valve 3 to chamber 16 to a valve parallel to the first restrictor 14.

The operation of the apparatus is as follows. The patient begins to manually compress valve 3 and the manometer 2. Generate pressure. The air passes through the annular opening 13 and the one-way flap valve 1 5 into the inner tube 11 and the manometer from the outlet 12 through the tube 5. flows into the tank 2. At the same time, air flows through the annular opening 13 to the second restrictor 11 4 to chamber 16 and then to the atmosphere. At the same time, air passes through the opening 17. passes through the second restrictor 15 into the chamber 16, and then into the atmosphere. leak. When valve 3 is released, air simultaneously flows into valve 3 through second valve 18 and second valve 18. 2 restrictor 15 while the air inside tube 5 returns to chamber 16. It flows out to the atmosphere through the first restrictor 14.

The pumping action on the heart-shaped valve 3 provides a manometric view of normal circulatory "blood pressure" readings. display on data 2. For example, the reading of manometer 2 is between 70 and 130 mmHH. circulate. The patient will now see that the force required to compress valve 3 will cause the heart to The normal demand is measured and the displayed pressure is measured with the manometer 2.

The patient simulates a high blood pressure reading by varying the frequency of compressions and the pressure applied to the valve. You can get the power you need to start.

The pumping action that compresses valve 3 causes further air to flow into valve 3 and It acts to cause the air in the tube to flow out through the first restrictor 14. Manome The reading of data 2 can be maintained by the frequency and pressure of compression of valve 3. .
