Description

A kind of water drainage device for airtight ventilator

technical field

The utility model relates to the technical field of medical equipment, in particular to a water drainage device for a closed ventilator.

Background technique

In modern clinical medicine, the ventilator is a vital medical device that can assist in the treatment of respiratory failure, respiratory support, save and prolong the life of patients. It is used for respiratory failure caused by various reasons, anesthesia respiratory management, respiratory support therapy and emergency recovery during major surgery. Among the currently used ventilators, both invasive ventilators and non-invasive ventilators use steam humidification for heating and humidification. During use, both the inhalation circuit and the exhalation circuit will bring more water due to humidification, and Concentrated in the water accumulation cup in the breathing circuit, it is often necessary for clinical medical staff to dump the water accumulation cup in a timely manner. When there are many patients who need care, the workload and labor intensity are high, and it is easy to be untimely or delayed. This is not conducive to the control of ventilator-associated pneumonia. At the same time, the ventilator will leak when dumping the accumulated water, which will affect the ventilation effect of the patient. At the same time, the treatment of the accumulated water in the ventilator will increase environmental pollution. In addition, the accumulated water needs to be stored in a special condensate collection bucket , the lid must be opened manually, which is extremely inconvenient to operate.

Utility model content

In order to overcome the above-mentioned technical defects, the purpose of this utility model is to provide a closed ventilator water drainage device suitable for invasive and non-invasive ventilators, which is simple and convenient to operate, can greatly reduce the work intensity, and has a simple structure. .

In order to achieve the above object, the utility model is realized through the following technical solutions:

The technical solution is a kind of water drainage device for airtight ventilator, including suction circuit storage cup, exhalation circuit storage cup and Y-shaped drainage tube. The two sides of the exhalation circuit water cup are respectively connected to the exhalation tube and the exhalation connection pipe of the ventilator. Both the inhalation circuit water cup and the exhalation circuit water cup are connected to each other through the connection holes at the bottom of the cup. The tube end of the upper part of the Y-shaped drainage tube is connected, the lower tube body of the Y-shaped drainage tube is provided with a clip switch, and a cap is set on the port of the tube body.

By setting water accumulation cups on the inhalation circuit and exhalation circuit respectively, and using a Y-shaped drainage tube to simultaneously drain the effusion collected in the water accumulation cups on the two circuits from top to bottom, and then pass through the Y-shaped drainage tube After the lower tubes are collected, they will be collected and stored in a centralized manner. Nurses only need to open the clip switch to keep the drainage tube open, and connect the negative pressure suction pipeline to automatically realize the suction and collection of the accumulated water in the water storage cup. in a closed drainage bottle.

Compared with the prior art, the beneficial effect of the utility model is: the utility model adds a water storage cup Y-shaped drainage tube, a clip switch and other components, connected with a negative pressure suction device, and assembled into a product for assisting the ventilator. The water drainage device has the advantages of simple structure, easy assembly and fast drainage, which can greatly reduce the labor intensity and workload of medical staff, and is simple and convenient to operate. Compared with the traditional unscrewed water cup, the air leakage is less , To ensure the effective ventilation of the ventilator, no special collection bucket for collecting condensed water is required, reducing pollution, and beneficial to the control of ventilator-associated pneumonia.

This solution also includes other optimization and optimization methods:

1. The length of the upper two tube bodies of the Y-shaped drainage tube is 100-150 mm, and the tube diameter is 5 mm. (Ensure that the two water storage cups are at the lowest position, and the upper two tubes of the same Y shape will not pull the pipeline. The diameter of the tube is for the purpose of effective drainage, so as to prevent excessive air leakage of the ventilator when the negative pressure suction is turned on. more, affecting the ventilation effect of the patient)

2. The length of the lower body of the Y-shaped drainage tube is 50 mm, and the diameter is 5 mm, so as to ensure effective drainage.
