Pressure reference reset method and structure of air mattress

Abstract

The pressure reference reset method and structure of the air bed of the present invention, the air bed includes at least two groups of air bag strips arranged in a staggered interval, the front end of the air bed is connected to a valve body, an air pump and a central control unit , and a pressure sensing component in the central control unit is connected with a pressure measuring tube of the valve body, and an atmosphere communication hole is arranged in the valve body. The valve body of the present invention firstly inflates the two groups of airbag strips, then chooses one to exhaust and the other to block the air. At the same time, through the exhaust state, the atmospheric communication hole is also communicated with the pressure measuring tube so that it is connected with the pressure measuring tube. When the external environment is in a conduction state, the external environment pressure measurement and the action of resetting the reference pressure can be performed, and the subsequent pumping can be performed according to the reference pressure. Thereby, the pump air pressure of the air mattress of the present invention is constant and can be measured at any time, and will not be affected by the altitude or temperature difference of the place of use, which will cause problems such as pressure inaccuracy and discomfort when lying on the human body.

Description

technical field [0001] The present invention relates to a method and structure for resetting the pressure reference of an air mattress, in particular to a technical field in which the internal pressure of an air mattress can be reset in real time so as to be accurate and constant. Background technique [0002] Patients who lie on the hospital bed for a long time, because of the body weight for a long time, and the long-term contact between the skin and the bed, often lead to the phenomenon of decubitus ulcers with tissue necrosis due to poor blood circulation and long-term pressure. In order to prevent the patient from getting bedsores, the most effective way is to let the patient lie down on the air bed with exchangeable air intake. In this kind of airbed, there are multiple airbag strip groups that can exchange air intake and exhaust, and use a valve body to control the airbag. The gas is exchanged to fill and deflate, so that the air mattress can achieve an alternate and ...

Problems solved by technology

[0005] In order to improve the above-mentioned problems such as the discomfort of inflation pressure when the existing air bed is used in places with different altitudes and high temperature differences, the main purpose of the present invention is to provide a method and structure for resetting the pressure reference. The air bed can be provided in the place of use In the operating place, the real-time measurement of the external environment pressure is carried out several times a day. Even if the temperature difference between day and night in the place is extremely large and will affect the pressure value, the pressure can be reset in real time after returning to zero, and the pump gas is required to be the correct pressure value.
