Automatic water adding device of humidifying tank and using method of automatic water adding device

Abstract

The invention relates to the technical field of medical treatment, in particular to an automatic water adding device of a humidifying tank and a using method thereof. The automatic water adding device comprises a sterile distilled water tank, an integrally-formed water outlet hole is formed in the bottom of one side of the sterile distilled water tank, a pipeline is fixedly arranged on the surface of the water outlet hole, and a peristaltic pump is fixedly arranged at the end, away from the sterile distilled water tank, of the pipeline; a humidification tank is fixedly arranged at the end, away from the sterile distilled water tank, of the peristaltic pump through a pipeline, a humidification tank water injection hole is fixedly formed in the top of the humidification tank, the pipeline is fixed to the surface of the humidification tank water injection hole, the peristaltic pump is communicated with the humidification tank through the pipeline and the humidification tank water injection hole, and an air outlet is fixedly formed in the top of the humidification tank. The invention has the beneficial effects that the device can be used for controlling humidifying liquid for invasive / noninvasive mechanical ventilation and high-flow oxygen therapy to be matched with humidifying tanks of various new and old models; the liquid level is accurate, controllable and adjustable whole-course trusteeship is achieved, and manpower and material resources are saved; compared with similar products, the cost is only 1 / 3, and the device can be repeatedly used; the product can be sold as a commodity, and brings economic and social benefits after being put into production.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an automatic water adding device for a humidification tank and a method for using the same. Background technique [0002] The oral and nasal cavity is the most important humidification organ, which supplements most of the lack of humidity. The establishment of an artificial airway bypasses the upper respiratory tract, which loses the role of the upper respiratory tract in heating, humidifying and filtering the inhaled gas. The artificial airway The establishment makes the isothermal saturation line move down. Both domestic and foreign airway humidification guidelines recommend that patients with invasive and non-invasive mechanical ventilation and high-flow oxygen therapy should be given continuous airway humidification through an active heated humidifier, while traditional humidification fluid Adding method: connect an ordinary infusion set to a heated humidifier, and manually ...

[0002] The oral and nasal cavity is the most important humidification organ, which supplements most of the lack of humidity. The establishment of an artificial airway bypasses the upper respiratory tract, which loses the role of the upper respiratory tract in heating, humidifying and filtering the inhaled gas. The artificial airway The establishment makes the isothermal saturation line move down. Both domestic and foreign airway humidification guidelines recommend that patients with invasive and non-invasive mechanical ventilation and high-flow oxygen therapy should be given continuous airway humidification through an active heated humidifier, while traditional humidification fluid Adding method: connect an ordinary infusion set to a heated humidifier, and manually raise the liquid level to an appropriate water level to ensure the humidification effect. The process of adding water (about 1-3 minutes) requires medical staff to control the infusion set throughout the process Flow regulator and observation of the liquid level of the humidifier; lack of distilled water, dry and hot gas leads to lack of humidity, affecting the normal function of the airway mucous membrane and cilia, resulting in thick sputum, sputum scab, dehydration, and affecting ventilation; adding too much distilled water, excessive Too much distilled water will flow back to the breathing circuit, causing the patient to inhale, which brings fatal risks; the existing floating check valve principle at home and abroad can automatically heat the humidifier to avoid irregular operation and cause the liquid level to overflow
