A method and device for automatically outputting oxygen and displaying oxygen concentration

Abstract

The invention relates to a method for automatically outputting oxygen and displaying oxygen concentration. The method includes the following steps: providing an oxygen storage device and a power device, processing the measurement data from the tension sensor, the gravity sensor and the temperature sensor through a signal processor, and comparing the different times before and after the oxygen output Point measurement data, to obtain information such as the concentration of inhaled oxygen, the estimated remaining time of use, etc.; display the processing information from the signal processor through the display; the signal processor controls the motor in the reel according to the pull force sensed by the pull sensor stop and start, so as to control the rotation of the reel, and the oxygen in the oxygen storage is automatically output through the rotation of the reel. The invention also provides a medical oxygen bag oxygen supply control device adopting the method. The method of the invention can automatically adjust the output of oxygen, and display information such as oxygen concentration when the oxygen is output, and has wide applicability.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a method for automatically outputting oxygen and displaying oxygen concentration, and a corresponding oxygen supply control device for a medical oxygen bag. Background technique [0002] Oxygen bag is a medical equipment used for emergency rescue or transfer of patients. When it is necessary to supply oxygen to the patient, connect the air delivery tube of the oxygen bag to the patient's oxygen inhalation tube, and then open the valve. [0003] When the existing oxygen bag supplies oxygen, the pressure of oxygen in the oxygen bag must be greater than the atmospheric pressure, and the oxygen in the bag can be supplied to the patient through the pressure difference inside and outside the oxygen bag. If the oxygen pressure in the oxygen bag is equal to or lower than the atmospheric pressure, Then oxygen can't supply oxygen to patient automatically, must adopt the method for extruding by...

AI Technical Summary

Problems solved by technology

[0003] When the existing oxygen bag supplies oxygen, the pressure of oxygen in the oxygen bag must be greater than the atmospheric pressure, and the oxygen in the bag can be supplied to the patient through the pressure difference inside and outside the oxygen bag. If the oxygen pressure in the oxygen bag is equal to or lower than the atmospheric pressure, Oxygen cannot automatically supply oxygen to the patient, and the method of external force extrusion must be used to output oxygen.

[0004] Existing oxygen bags use external pressurization to maintain the pressure of the oxygen bag, which is very inconvenient to use

When filling the oxygen bag with oxygen, the oxygen bag cannot display the filled oxygen capacity and the pressure inside the oxygen bag. Big enough to make the oxygen bag burst, or the oxygen inflated is too low, affecting the use of the oxygen bag

In the process of using oxygen as a medical treatment method, different oxygen concentrations need to be adopted in different situations to achieve the desired effect. The existing oxygen bags can only adjust the flow of oxygen according to the feeling, and cannot accurately display the specific flow and oxygen. Concentration, and do not know the remaining amount of oxygen in the bag and other information, it is very easy to cause the effect of oxygen inhalation to fail to achieve the expected effect and the oxygen in the oxygen bag is exhausted during the transfer, causing danger to the user
