Automatic water adding device for breathing machine

Abstract

The invention discloses an automatic water adding device for a ventilator, which comprises a ventilator humidification tank body (1), and the ventilator humidification tank body (1) is provided with an air inlet (2) and an air outlet (3). The ventilator humidification tank body (1) is also provided with a water inlet hole (4) for connecting the nipple of the infusion set, and it is characterized in that: the ventilator humidification tank body (1) is provided with a base (5 ), the base (5) is provided with a suspension device, the ventilator humidification tank body (1) is provided with a limiting device for limiting the suspension device, the suspension device and the water inlet ( 4) Correspondingly, the water inlet hole (4) can just be blocked when the suspension device rises. The arrangement of the automatic water adding device of the present invention can realize the automatic water adding of the humidifying tank of the ventilator without personnel supervision, saves time and effort, can ensure effective heating and humidification of the gas entering the patient's body, and saves time and cost.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic water filling device for a ventilator. Background technique [0002] With the gradual increase in the clinical use of ventilators, how to do a good job of airway humidification so that the gas entering the patient's body reaches a certain humidity and temperature has become a clinical problem that needs to be solved urgently. [0003] Most ventilators in the prior art use a humidification tank to heat and humidify the inhaled gas. In order to ensure the temperature and humidity of the inhaled gas, the humidification tank needs to be continuously added with distilled water. There are three conventional methods for adding water in clinical practice: 1. Separate the ventilator and the air intake pipe and pour it from the air intake hole; the second is to use a syringe to extract distilled water and inject it from the water intake hole; the third is to use an i...

Problems solved by technology

In actual work, it is found that disconnecting the ventilator pipeline to add water and using a syringe to add water need to disconnect the ventilator pipeline, so that the patient's breathing state will change temporarily, which will bring inconvenience to the patient's treatment. At the same time, the ventilator pipeline will be increased due to repeated disconnection of the circuit The chance of infection, the third method is ideal, but this method requires manual care when adding water, because adding too little water will not be effective, and adding too much water may cause the patient to have a drowning reaction or even suffocation In this way, not only does it not have a therapeutic effect, but it aggravates the patient's condition, and even endangers the patient's life. Therefore, when adding water, a special person is required to take care of it. Although this can prevent the above problems from happening, it is a waste of time and delays in treatment.
