Method for automatically outputting oxygen and displaying oxygen-absorption concentration and device thereof

Abstract

The invention relates to a method for automatically outputting oxygen and displaying oxygen-absorption concentration. The method includes the steps of: providing an oxygen storage device and a power device, processing measurement data from a tension sensor, a gravity sensor, and a temperature sensor through a signal processor, by comparing measurement data at different time points before and afteroutputting oxygen, obtaining the information such as the concentration of inhaled oxygen and the estimated remaining time; displaying the processing information from the signal processor on a display; controlling the stop and start of the motor in a roll by the signal processor according to the magnitude of the pull force sensed by the tension sensor, and controlling the rotation of the roll, andautomatically outputting the oxygen in the oxygen storage device through the rotation of the roll. The invention also provides a medical oxygen bag oxygen supply control device using the method. Themethod of the invention can automatically adjust the output of oxygen, and displays information such as oxygen concentration when outputting oxygen, 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
