Description
Technical Field
The utility model relates to a blood pressure measurement technical field especially relates to a diver uses underwater blood pressure measuring device.
Background
The blood of the human body flows in blood vessels as well as water in watercourses, and is usually silent. But sounds can be generated when a vortex is formed through a narrow tube, and a sphygmomanometer for a human blood pressure is designed according to the principle.
The electronic sphygmomanometer adopted at present is that a cuff is tied on an arm, the cuff is automatically inflated through an inflator pump, and pressure acts on the popliteal artery through soft tissue. When the pressure is up to a certain pressure (generally 30-50 mmHg higher than the systolic pressure), the pressurization is stopped, and the popliteal artery is pressed by the pressure and no blood flows through the popliteal artery. And then, the air is deflated, when the air pressure is reduced to a certain degree, the blood flow can pass through the blood vessel, certain oscillation waves exist, the oscillation waves are transmitted to the pressure sensor through the blood vessel, and the pressure sensor can detect the pressure and the fluctuation in the measured cuff in real time. The earliest measured data is systolic pressure, air is gradually released, and the oscillation wave is larger and larger. The more loose the cuff is in contact with the arm, the less the pressure and fluctuation the pressure sensor detects, and the last data measured is the diastolic pressure.
At present, the electronic sphygmomanometer on the market can conveniently detect the blood pressure value of a human body, but under the special underwater environment, the electronic sphygmomanometer in daily use cannot be used, and the influence of underwater external air pressure on the blood pressure value under waterproof and underwater environments and the like are not considered.
When a diver dives, the body of the diver is soaked in water, and the physical effect of the underwater pressure can cause physiological reaction, so that the vital signs are changed, and the changes are also closely related to the development of diving diseases. Arterial blood pressure is one of the most important vital signs, reflecting the heart's ability to supply blood to peripheral blood pressure. There are several methods for measuring blood pressure, such as manual techniques using cuffs, mercury barometers listening to Korotkoff sounds, and oscillometric based digital sphygmomanometers. However, under water and a special pressurized environment, the current sphygmomanometer cannot be used under water due to the reasons that the system is not waterproof and pressure-resistant, air in the environment cannot be directly injected into a cuff under water, Korotkoff sounds cannot be auscultated by noise of a respirator, and the like.
