Automatic oxygen therapy adjusting apparatus for nursing critical patients

Abstract

The invention discloses an automatic oxygen therapy adjusting apparatus for nursing critical patients. The automatic oxygen therapy adjusting apparatus for nursing the critical patients comprises a sleeve, an elastic film, a pressure adjusting mechanism, an oxygen adjusting mechanism, an oxygen outlet and an oxygen inlet; the sleeve is connected with a piston in a sliding manner, a manual adjusting mechanism is arranged above the piston, the oxygen adjusting mechanism is arranged below the elastic film, the oxygen adjusting mechanism comprises a vertical rod, a straight rod, a connecting mechanism, a valve and a support, the sleeve on the position of the valve is provided with a through circular oxygen inlet, the oxygen outlet is arranged on a position, symmetric to the axis, of the oxygeninlet, when in use, the oxygen inlet is connected with an oxygen tank, and the oxygen outlet is connected with an oxygen mask. The automatic oxygen therapy adjusting apparatus is reasonable in structure design, when the oxygen demand of the patient is increased, the oxygen amount sucked from the oxygen outlet is increased, resulting in the reduction of air pressure in an air chamber, under the effect of external atmospheric pressure, the piston slides downwardly to drive the right end of the straight rod to be lowered and the left end to rise, the opening degree of the valve is increased, andthe oxygen supply amount is increased; and conversely, the oxygen amount respired by the patient from the oxygen outlet is reduced, and the oxygen supply amount is reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an automatic adjustment device for oxygen delivery used in the care of critically ill patients. Background technique [0002] Severely ill patients have poor internal circulation and high nutrient levels during or after the operation, so they need oxygen infusion during or after the operation to assist treatment; the traditional hospital oxygen supply system connects oxygen tanks and oxygen masks with hoses, The middle of the hose is connected to the moisture bottle and the oxygen flow adjustment device. This flow adjustment device needs to manually control the oxygen flow rate. However, during or after the operation, the amount of oxygen required by the patient is changing at any time, and it is impossible to arrange a special person at any time. Adjusting the oxygen flow has caused the patient to suffer from insufficient or excessive oxygen supply during the actual treatment proc...

[0002] Severely ill patients have poor internal circulation and high nutrient levels during or after the operation, so they need oxygen infusion during or after the operation to assist treatment; the traditional hospital oxygen supply system connects oxygen tanks and oxygen masks with hoses, The middle of the hose is connected to the moisture bottle and the oxygen flow adjustment device. This flow adjustment device needs to manually control the oxygen flow rate. However, during or after the operation, the amount of oxygen required by the patient is changing at any time, and it is impossible to arrange a special person at any time. Adjusting the oxygen flow has caused the patient to suffer from insufficient or excessive oxygen supply during the actual treatment process. Insufficient oxygen supply is not conducive to the effect of surgery and the process of postoperative rehabilitation. Excessive oxygen supply may cause adverse consequences such as oxygen poisoning.
