Portable first-aid breathing bag for oxygen supply and breath detection

Abstract

The portable first-aid breathing bag comprises a connector, a Y-shaped pipe, a threaded pipe, a rubber balloon and an air valve, the connector is detachably connected with the Y-shaped pipe through threads, the lower end of the Y-shaped pipe is detachably connected with the threaded pipe, the lower end of the threaded pipe is detachably connected with the rubber balloon, and the air valve is installed at the tail end of the rubber balloon. The emergency oxygen supply device can quickly supply oxygen to a patient in emergency, and is convenient to carry and simple to operate; an oxygen supply device is connected, so that oxygen can be continuously supplied to a patient; the internal examination port is arranged, so that sputum suction, gastroscope, bronchofiberscope and other internal examinations can be carried out on the premise of not influencing ventilation; the sealing degree of the air valve can be freely adjusted between 0% and 100%, corresponding adjustment can be conveniently carried out according to patients with different illness states, carbon dioxide is supplemented in time for the patients with tachypnea, and complications are avoided; meanwhile, the device is suitable for adults and children and can be used for breathing extubation transition and observation of postoperative resuscitation of general anesthesia patients.

Description

technical field [0001] The invention belongs to the technical field of breathing oxygen supply, and in particular relates to a portable emergency breathing bag used for oxygen supply and breathing detection. Background technique [0002] Respiration is 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 transportation in the blood; internal respiration, which refers to the gas exchange between tissue cells and blood and the oxidative metabolism in tissue cells. For normal adults, it is optimal to take a breath of 6.4 seconds at a time, and the amount of gas inhaled and exhaled each time is about 500 ml, which is called tidal volume. When people inhale hard until they can no longer breathe; and then exhale forcefully until they can no longer breathe out, the amount of gas exhaled at this time is called vital capaci...

AI Technical Summary

Problems solved by technology

[0005] Single use, for patients who need oxygen inhalation and assisted ventilation, gastroscopy, bronchoscopy, laryngoscopy and other examinations cannot be performed at the same time; it cannot be disassembled, or it cannot be used in combination with other assisted ventilation tools; the breathing bag is too large, and it is easy to perform assisted ventilation. The tidal volume is too large or not synchronized with the patient, causing barotrauma; the oxygen storage bag is easily damaged; the valve of the breathing bag is easily damaged; the breathing valve is not easy to control and is easily interfered by external factors; the self-test method of the breathing bag is complicated and difficult to master
