Abstract

The invention relates to a medical breathing hood having the fresh air function. Fresh air rich in negative ions of proper temperature is continuously provided for a transparent hood through a fresh air cooling and heating machine, more comfortable oxygen therapy is achieved together with a breathing machine, compared with a nasal catheter and mask oxygen inhalation method, the medical breathing hood disclosed by the invention is closer to a natural breathing mode, breathing resistance is avoided, illness state changes can be observed easily through the transparent hood, the oxygen concentration, temperature and negative ion concentration in the transparent cover can be adjusted, and good conditions are created for oxygen therapy of different illness states. A semiconductor refrigerator isa current transduction type device, and high-precision temperature control can be achieved through control of input current.

Description

technical field [0001] The invention relates to a medical breathing hood equipment, in particular to a medical breathing hood equipped with a fresh air function. Background technique [0002] At present, medical institutions often use nasal catheter oxygen inhalation and mask oxygen inhalation in two ways. [0003] Nasal cannula oxygen: A catheter is inserted into the top of the nasal cavity to inhale oxygen. [0004] Advantages: 1. It is simple, cheap, convenient and comfortable; 2. It does not affect eating and drinking. [0005] Disadvantages: 1. The concentration of inhaled oxygen is affected by the ratio of inspiratory tidal volume, flow rate and breathing time; 2. The nasal cannula is easy to be blocked; 3. It is irritating to the local area and can cause dry sputum; 4. Intolerance. [0006] Oxygen inhalation by face mask: Cover the patient's mouth and nose with a mask to inhale oxygen. [0007] Advantages: 1. Non-irritating, suitable for patients with mouth breathi...
