Novel oxygen humidifying device

Abstract

The invention relates to a novel oxygen humidifying device which is used in clinical oxygen therapy. The novel oxygen humidifying device mainly comprises a humidifying object (1), a humidifying object container (2), a pressurizing jet device (3), an air flow blocking plate (4), an oxygen inlet (5), an oxygen outlet (6), a sealing plug (7), solid water absorbing materials (8), an oxygen filtering device (9), a liquid level float (10) and a heat transfer window (11). When the novel oxygen humidifying device is used, bubble noise is avoided, the volume of the humidifying object container can be greatly decreased, and manufacturing expenses are saved. The liquid level float (10) can be arranged on the surface of the humidifying object (1), the residual quantity of the humidifying object (1) is easily observed by nursing staff, humidifying liquid is heated by the heat transfer window when the novel oxygen humidifying device is used in winter, and oxygen absorption comfort is improved.

Description

Technical field [0001] The invention relates to a novel oxygen humidification device used in clinical oxygen therapy, which belongs to the category of medical instruments used clinically in hospitals. Background technique [0002] Oxygen therapy is one of the most commonly used rescue or treatment methods in hospitals. Because the humidity of oxygen itself is very low, long-term oxygen inhalation will cause adverse consequences such as dry respiratory tract, dry nasal mucosa and bleeding, and difficult coughing of sputum. Oxygen inhalation therapy generally needs to humidify the oxygen first. The oxygen humidification method widely used in hospitals at present is to fill the humidification liquid (generally sterilized water or distilled water) into the humidification cup (bottle) of the oxygen inhaler, and then through the inner core of the humidification cup (bottle) Oxygen escapes after passing through the humidifying fluid below the surface to humidify it, and finally en...

AI Technical Summary

Problems solved by technology

[0003] 1. Oxygen enters below the liquid level of the humidifying liquid and quickly escapes from the liquid surface. The residence time of oxygen in the humidifying product is extremely short, and the oxygen bubbles are large and cannot be dispersed. The unit contact area between oxygen and the humidifying liquid is very small, so The humidification effect is not ideal

[0004] 2. The noise of water bubbles produced when oxygen enters the humidification fluid brings discomfort to many patients, especially critically ill patients, heart failure patients and neurasthenia patients who need to rest quietly

[0005] The inventor once proposed a technical solution of "A Noiseless Oxygen Humidification Device (ZL200820177959.2)", which effectively solved the problem of water bubble noise during oxygen absorption and humidification

But at the same time, it is found in practice that due to the unbalanced oxygen flow rate (usually between 1 and 8 L / min) for each patient receiving different oxygen inhalation, this technical solution is incompatible with high oxygen flow when the oxygen supply is lower than 3 L / min. When supplying oxygen at a high flow rate of 5L / min, the humidity difference is relatively large due to the different airflow intensity generated by the input oxygen; and when the liquid level of the humidification liquid continues to drop, the oxygen humidification effect is weakened, and the humidity of the oxygen output by the humidification device also decreases. decrease

[0006] For this reason, the inventor proposed a new type of oxygen humidification device, which belongs to a new type of technical substantive improvement scheme of a noiseless oxygen humidification device, which effectively solves the problem of oxygen humidity generated when low flow oxygen is absorbed and the humidification is reduced. The attenuation problem of chemical effect
