Description

A non-humidified oxygen meter suitable for medium and low flow rates

Technical field

The utility model relates to the technical field of medical care products, and specifically relates to a humidification-free oxygen meter suitable for medium and low flow rates.

Background technique

Oxygen therapy refers to a method of increasing oxygen concentration into the airway under normal pressure through simple connecting pipes, referred to as oxygen therapy. Oxygen supply can increase arterial blood oxygen partial pressure and blood oxygen saturation, increase arterial blood oxygen content, correct hypoxia caused by various reasons, increase oxygen delivery, and ultimately improve physiological disorders caused by hypoxemia. Nasal cannula oxygen inhalation is a widely used oxygen therapy method in hospitals and communities.

Patients who inhale nasal oxygen are routinely humidified, that is, the oxygen meter first needs to be connected to the humidification bottle, then to the nasal oxygen tube, and finally a nasal plug is inserted into the patient's nasal cavity. However, humidified oxygen supply has the following problems: (1), the bubble noise formed during humidification will reduce the patient's sleep quality; (2), the storage and repeated replacement of humidification fluid may cause bacterial contamination; (3), every Daily replacement of disposable oxygen consumables not only increases the patient's financial burden, but also increases the nursing workload, making the clinical oxygen therapy process too cumbersome.

In the traditional concept, humidified oxygen can reduce irritation to the respiratory mucosa and improve patient comfort. However, some literature points out that the physical properties of oxygen are that it is not easily soluble in water. There is currently no evidence that oxygen can achieve a humidifying effect after being passed through a humidifying solution. The humidifying function of the respiratory mucosa itself and the humidity in the air have already affected oxygen. Provides sufficient humidification.

In recent years, many clinical practice guidelines have pointed out that humidification is not required when adults use nasal cannula oxygen therapy with medium and low flow (≤4L/min). Some domestic medical institutions have applied nasal medium-low flow oxygen therapy without humidification in clinical practice. , but currently there is no suitable integrated medium-low flow non-humidified oxygen meter available for clinical use.
