Description

An intelligent anti-reverse flow fan humidification tank automatic LU600335

Water filling device

Technical area

The present invention relates to the field of ventilators and, more particularly, to an intelligent anti-reverse flow ventilator humidification tank automatic

Water filling device.

Technology in the background

A ventilator is an important medical device that primarily serves to support or replace a patient's natural respiratory function. It supports the

Respiratory system during full ventilation by supplying oxygen-containing air to the lungs and expelling carbon dioxide-containing gases from the body. There are two types of

Ventilators: invasive ventilators that are delivered via tracheal intubation or

tracheotomy, and non-invasive ventilators that are connected directly to the patient via face and nasal masks.

Ventilators play an important role in the medical field and are often used in scenarios such as respiratory failure due to various causes, anesthesia during

Used for surgery, respiratory management, respiratory support therapy and emergency resuscitation.

There are several major problems with using conventional ventilators.

Firstly, the volume of the water tank is relatively limited, especially when the ventilator is running under high load for a long time, the water tank fills up very quickly, so the medical staff has to pour the condensate into the water tank frequently, which

This makes work very difficult. Secondly, there is also the problem of the limited volume of fluid in the humidification tank, which also requires frequent refilling of fluid.

In addition, it is easy to forget to check whether the liquid is below the

If the fluid level is below the minimum level, and if the fluid is not refilled in time or if the operation is interrupted, dry burning can occur. Dry burning not only leads to the drying of the respiratory tract, but also to the formation of mucous crusts and

Airway obstruction can slow the patient's recovery and, in severe cases, even lead to burns. At the same time, dry burning can also damage the instrument and shorten its lifespan.
