Respiration assisting device

Abstract

The invention discloses a respiration assisting device, which comprises a tube body, an inflation expansion body and an adhesive tape, wherein an air cavity and a through hole through which gas goes in or out of the air cavity are arranged in the inflation expansion body; the inflation expansion body is arranged on the inner side of the outer side tube body; the adhesive tape is arranged at the inward side of the inflation expansion body. According to the respiration assisting device disclosed by the invention, in the use process, the adhesive tape is stuck to a patient; through the inflationand deflation of the inflation expansion body, the inflation expansion body expands or contracts, so that the lung of the patient can expand or contract so as to assist the patient with respiration; the goal of restoring the respiration of the patient can be achieved. The traumatic operation on the patient is not needed; the injury and uncomfortable feeling are reduced; anesthesia is not needed; the infection due to long-time use does not need to be worried; in addition, the patient can restore the respiration in a short time because the preparation stage is concise; the rescue time is gained;the goal of restoring the respiration of the patient is achieved by simulating the respiration action of a normal person, so that the injury to the lung part is smaller, and the effect is more effective.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a breathing assistance device. Background technique [0002] Respiratory failure is often one of the direct causes of death in critically ill patients. When a patient's lungs cannot expand and contract spontaneously, fresh oxygen cannot be sucked into the body by the force of lung expansion, and the residual carbon dioxide in the body cannot pass through the air when the lungs contract. When the force is expelled from the body, the human body will die due to lack of oxygen and carbon dioxide retention. The most common existing assisted ventilation equipment is a ventilator. The principle is to insert it into the patient's trachea through a tube, and an external machine blows in and sucks out gas at an appropriate pressure to force the patient's lungs to expand and retract (only relying on the lungs). passive retraction rather than forceful contraction) to help the patien...

AI Technical Summary

Problems solved by technology

[0003] The existing ventilator has the following defects. First, before using this type of ventilator, the tube must be inserted into the patient's trachea using tracheal intubation technology, which brings the risk of injury to the patient. At the same time, the intubation fails, the preparation time is long and the rescue Time and infection caused by long-term intubation will increase the risk of patient death and additional treatment costs; the second is that the ventilator blows a certain pressure of gas from the inside of the lungs to force the lungs to be "blown", and this process can cause lung damage. Injury, exacerbation of the condition, and the contraction depends on the elastic retraction of the lung itself. When the lung elasticity decreases due to diseases such as emphysema or pulmonary fibrosis, it is difficult for the exhaust gas in the body to be effectively squeezed out of the body.
