Embodiment Construction

[0015] in such as figure 2 In the shown embodiment of the present invention, the controller 1 drives the stepper motor 3 according to the signal of the pressure difference sensor 2, and the controller includes a circuit; the pressure difference sensor 2 measures the pressure difference between the mask chamber 7 and the outside atmosphere ; The stepping motor 3 is connected with the core body 4 of the oxygen supply respirator to promote the core body 4 movement. The movement of the stepper motor 3 is controlled by the controller 1 .

[0016] In a specific embodiment, the movement stroke of the stepping motor 3 is 10mm.

[0017] like image 3 As shown, the control circuit 1 of the present invention includes a signal amplification part 31 , a digital-to-analog conversion and central processing part 32 , and a stepping motor driving part 33 . Wherein the signal amplifying part 31 is formed by circuit connection of an instrument signal amplifier, a resistor, a capacitor and a ...

Abstract

The invention provides an electronic low resistance oxygen providing respirator. Signals of a pressure difference sensor are processed to drive a stepping motor. When a person breathes, the stepping motor moves in a reciprocating way. The lung respiration is realized through the connection and disconnection of an air supply pipeline. The device can greatly lower the load of respiratory muscle when the person breathes. When in normal inhalation, the biggest resistance is not larger than 200Pa, and the biggest resistance is not larger than 100Pa during exhalation. The comfort of patients can beimproved, and the oxygen inhalation efficiency is improved. The electronic low resistance oxygen providing respirator can be widely applied to hyperbaric oxygen chamber therapy, family health care, etc.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a mechanical structure of an electronically controlled oxygen supply respirator and an electronically controlled device using the same. Background technique [0002] At present, the structure of the respirator used by the patient to inhale oxygen in the hyperbaric oxygen chamber or under normal pressure is as follows: figure 1 shown. It consists of a film air cavity, a soft cover, and a lever type air supply valve. When the respirator is used for oxygen inhalation, the negative pressure generated during inhalation of oxygen mainly overcomes the resistance of the elastic membrane of the respirator and the resistance of the air supply valve stem to achieve the purpose of oxygen supply. If the negative pressure produced during inhalation is less than the above two pressures, there will be no oxygen for breathing. In addition, the resistance generated by the air supply...
