Special respiratory auto-nursing apparatus for patients with mobility difficulties

Abstract

The invention discloses a special respiratory auto-nursing apparatus for patients with mobility difficulties, comprising a storage tank. A mounting pipe is fixedly communicated with the upper surfaceof the storage tank; the inner wall of the mounting pipe is provided with a filter cavity through a partition; an air filter is arranged in the filter cavity and includes a molecular sieve; the interior part, far away from the filter cavity, of the mounting pipe is provided with a power device; the power device comprises a miniature vacuum pump. The special respiratory auto-nursing apparatus for patients with mobility difficulties has the advantages that pressure of oxygen in the storage tank is automatically controlled; when the miniature vacuum pump supplies air continuously into the storagetank, pressure increases and compresses a piston rightward; when the pressure rises to a certain level, a fixing rod in the piston leaves a fixing groove; a power switch is off, and the miniature vacuum pump is powered off; when the pressure is low, a return spring ejects the piston to reset; the power switch is pressed, the miniature vacuum pump is controlled to start; therefore, the apparatus herein has the advantage of automatic control.

Description

technical field [0001] The invention relates to the technical field of respiratory medicine, more specifically, it relates to a special automatic nursing equipment for patients with disabilities in respiratory medicine. Background technique [0002] Respiration refers to the process of gas exchange between the body and the external environment. The human respiration process includes three interrelated links: external respiration, including lung ventilation and lung ventilation; gas transport in the blood; internal respiration, which refers to the gas exchange between tissue cells and blood. It is best for a normal adult to breathe once at a time of 6.4 seconds, and the volume of gas inhaled and exhaled each time is about 500 milliliters, which is called tidal volume. When a person inhales hard until he can no longer inhale; and then exhales hard until he can no longer exhale, the amount of gas exhaled at this time is called vital capacity. [0003] At present, most of the ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the respiratory equipment used by patients with limited mobility is used in a fixed place. When the patient needs to move, it is obvious that the oxygen breathing equipment is difficult to carry, causing a certain degree of inconvenience in use, and ordinary manual control of oxygen equipment It is easy to bring inconvenience to patient control. At the same time, ordinary air filtration and purification devices can only filter out solid impurities in the air, but it is difficult to filter out more harmful gases in the air.
