Volum-controlled type simple respirator

Abstract

The invented volumetric simple respirator is amied at to make the air quantity more accurate. It includess breathing bag, handle and clamping hoop, fixed rod and scale; handle includes fixed handle and movable handle, the fixed handle and movable handle are respectively connected with breathing bag by clamping hoop, the breathing bag between fixed handle and movable handle bas a section of foldable position; the movable handle has a hole for fixed rod and scale to pass through, the scale shows weight of human body, the skirt of scale has teeth, the scale has clamping wheel which has internal thread matching with the skirt teeth of scale. The present invention is suitable for emergency rescue and auxiliary respiration of critical patient.

Description

technical field [0001] The invention relates to an improvement of a simple respirator. Background technique [0002] The simple respirator is clinically also called a ball or a breathing bag, and is used for emergency rescue and assisted breathing of critically ill patients. When there is no ventilator and assisted breathing is needed, or due to power failure, ventilator failure or on-site temporary rescue, the simple respirator becomes the only means of artificial ventilation for the patient. Existing simple respirator is mainly divided into two kinds of children and adults, but no matter what kind, its main structure is exactly two valves (intake, outlet) plus an approximately elliptic rubber skin bag, when using, the ball is kneaded by medical staff. The bladder allows the patient to be ventilated. Existing breathing bag has the following disadvantages when in use: (1) The patient's body weight is different, and the required tidal volume (gas supply volume for one breat...

AI Technical Summary

Problems solved by technology

Existing breathing bag has the following disadvantages when in use: (1) The patient's body weight is different, and the required tidal volume (gas supply volume for one breath) is different, and there is no capacity control device on the existing simple respirator, and the ventilation volume is determined by the operator's feeling. Therefore, the ventilation volume is extremely inaccurate, and it is acceptable in the short term, but long-term application will endanger the life of the patient due to excessive or too little ventilation.

(2) The size of the user's hands varies, and accurate ventilation cannot be guaranteed; each time the squeezing force is different, the air supply is also different; the same patient, the same breathing bag, is used by different medical staff, and the air supply is different. Not the same, affect the patient's treatment effect
