Description

Prevent mistake and inhale safe type breathing machine humidifying jar water feeder

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a prevent mistake and inhale safe type breathing machine humidifying jar water feeder.

Background

Patients with severe symptoms such as respiratory failure, surgical anesthesia and multi-organ failure generally need to establish an artificial airway and use an invasive ventilator for assisted ventilation. The compressed air and oxygen enter the humidifying tank through the pipeline to be heated and humidified to reach a state close to physiology, and then are sent into the airway of a patient through another pipeline. The humidifying cylinder structure is shown in figure 1. The humidifying tank is internally provided with a complete cavity, two larger openings at the top end are connected with a pipeline for gas to enter and exit, and the top end is also provided with a small opening with a sealing plug. The bottom of the humidification tank is a flat metal heating part, the water adding height is generally maintained at about 3cm, and a space is reserved above the humidification tank, so that dry and cold gas can be quickly warmed and humidified after passing through the humidification tank. At present, 3 humidification tank water adding modes exist.

The first method comprises the following steps: the ventilator circuit was disconnected directly and sterile distilled water was poured directly from the disconnected tubing. This method has a number of disadvantages: firstly, because the gas directly enters the trachea without nasal cavity filtration, adhesion, heating and humidification and lack of protection, once the breathing machine pipeline is disconnected, microorganisms, dust and the like can enter the airway to bring the risk of relevant pneumonia of the breathing machine; secondly, some patients have great dependence on oxygen supply and need large support force of a breathing machine, and when a breathing machine pipeline is disconnected, the pressure and the oxygen content suddenly drop, so that the patients cannot tolerate the pressure and the oxygen content; and thirdly: once the breathing machine pipeline is disconnected, a patient with respiratory infectious diseases can pollute the surrounding environment and cause infection of other people.

And the second method comprises the following steps: the loop of the breathing machine is not broken, and the sterilized distilled water is added into the humidification tank by using the infusion apparatus. The specifications of sterilized distilled water currently used clinically are usually 500ml and 1000 ml. In clinic, a nurse forgets to close the infusion apparatus when adding water, so that the liquid is infused into the airway of a patient after the humidification tank is filled with the water, and the patient inhales by mistake or even suffocates. Unless isolated or severely ill patients with lung conditions, there are generally few hospitals darning to risk high risk of adding water using this method.

And the third is that: and (5) pumping the sterilized distilled water by using an injector, and adding water into the small holes of the humidification pot. The method has low efficiency, and the water level requirement can be met by repeatedly pumping water for many times. The effect of this approach on the patient's oxygen supply is between the first two, but the risk of infection remains high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a water feeder for a humidification tank of a safety type respirator preventing mistaken inhalation.

The purpose of the utility model is realized through the following technical scheme: a water feeder for a safety type anti-aspiration respirator humidification tank comprises a sterilized distilled water joint, a liquid storage bag, a tee joint, an L-shaped tee joint opening knob, a humidification tank, a closable filtering air hole and a hose;

the sterilizing distilled water joint is connected with sterilizing distilled water, the sterilizing distilled water joint is connected to a first vent hole of a tee joint through a hose, and a third vent hole of the tee joint is connected to a liquid inlet of the humidifying tank through the hose; a second vent hole of the tee joint is connected to an outlet of the liquid storage bag through a hose; the height of the liquid storage bag is lower than that of the sterilized distilled water joint; the L-shaped tee opening knob is arranged inside the tee.

Furthermore, a closable filtering air hole is arranged on the hose close to the outlet end of the sterilized distilled water joint.

The utility model has the advantages that:

1. no matter which direction the tee joint turns to, the liquid can not be directly sterilized and distilled water joints flow to the humidification tank. The risk of liquid filling into the airway of the patient is avoided. The operation is safe and simple for clinic, and the workload of nurses is reduced.

2. The water feeder is a closed pipeline, so that gas cannot leak when water is fed, and oxygen deficiency of a patient or infection of surrounding personnel cannot be caused; meanwhile, microorganisms and dust are reduced from entering the airway of the patient.

3. The respirator is a precision instrument and is sensitive to airflow. The water feeder does not influence the internal structure of the humidifying tank and does not hinder the air flow in the tank to pass through.

4. The water feeder can be directly matched with the original water feeding hole of the humidification tank.

5. The water feeder is a disposable medical consumable, has a simple structure and low cost, can be used by one person and is discarded after use, so that the risk of cross infection is reduced.

6. The joint of the water feeder can be directly inserted into the clinically existing bottled or bagged sterilized distilled water, so that the new sterilized distilled water can be conveniently replaced at any time.
