Example Embodiment

[0018] See Figure 1 to 4 , A medical pressure gauge, comprising a bottom fixing plate 10, and a top fixing plate 9 placed on one side of the bottom fixing plate 10. There is a gap between the top fixing plate 9 and the bottom fixing plate 10, and the size of the gap is The thickness of the 20mm top fixing plate 9 and the bottom fixing plate 10 is 0.8mm, and the four frames of the top fixing plate 9 and the bottom fixing plate 10 are provided with fixing holes (not marked), and the diameter of the fixing holes is 2.7mm , The fixed hole is fixed with a round fixing column 1, the diameter of the round fixing column 1 is 2mm, the two end faces of the round fixing column 1 are attached to the two inner wall surfaces of the gap respectively, the number of the round fixing column 1 is four Two of them are placed in the long frame of the bottom fixing plate 10, and the other two are placed in the short frame of the bottom fixing plate 10. The distance between the two round fixing post...

Abstract

The invention discloses a medical pressure measuring instrument. The medical pressure measuring instrument comprises a bottom fixing board and a top fixing board arranged on one side of the bottom fixing board, fixing holes are formed in the top fixing board and the four rims of the bottom fixing board, round fixing columns are fixedly connected to the fixing holes, locating holes are formed in the surfaces of the top fixing board and the bottom fixing board, a gear shaft and a rotating shaft are connected into the locating holes in a matched mode, a flat spiral spring is fixedly connected tothe outer side surface of the gear shaft, the outer side surface of the rotating shaft is sleeved with a sector gear, the head of the sector gear is connected with the gear shaft in a meshed mode, thetail of the sector gear is connected to a connecting rod, a seal is arranged on the tail of the connecting rod, and the bottom of the seal is fixedly connected to a sensor device in a catheter. Through the structure of the flat spiral spring of the medical pressure measuring instrument, subtle changes of pressure can be sensitively measured, so that an air pressure value of a pressure instrumentis precisely measured, and failures of the pressure instrument are prevented.

Description

technical field [0001] The invention relates to a medical manometer. Background technique [0002] The pressurized instrument generates air pressure and transmits it to the spherical object at the top through the catheter. The spherical object expands to open the blocked blood vessel in the body. Since the blood vessel wall is subjected to unstable pressure, it will burst and ooze blood, so it is necessary to ensure that the error of the air pressure value of the catheter is extremely small Within the scope of the medical pressure gauge, the medical pressure gauge is a device used to measure the air pressure of the pressure catheter. However, due to the insufficient sensitivity of the internal parts of some medical pressure gauges, it is difficult to detect the slight changes in the air pressure value in the catheter, so the medical pressure gauge There is an error between the measured pressure value and the actual value, which will inevitably lead to the failure of the medi...
