Description

Automatic water collecting cup drainage and collection device for breathing machine pipeline based on buoyancy principle

Technical Field

The utility model relates to a breathing machine pipeline technical field especially relates to a breathing machine pipeline is with automatic drainage of cup and collection device catchments based on buoyancy principle.

Background

The respirator is a medical device which can prevent and treat respiratory failure, reduce complications and save lives of patients, however, in the process of applying the respirator, because inhaled gas is heated and humidified, a large amount of condensed water is often generated in a breathing circuit. There is data showing that mechanically ventilated patients produce approximately 1000ml of condensate water per day. The condensed water is the most easily infected part in the breathing machine pipeline and is also the most easily accumulated part of bacteria. Chuaiwei et al, in the management of condensate in mechanical ventilation lines, indicated that pathogenic bacteria are liable to parasitize in condensate and that ventilator-associated pneumonia (VAP) can also be caused after condensate containing bacteria flows back into the lower respiratory tract. The breathing machine mainly forms a closed circulation state with the patient using the breathing machine and the breathing machine pipeline, when the mechanical ventilation time of the patient is prolonged, the growth rate of bacteria at each part in the breathing machine pipeline is increased, and the bacteria can pollute the whole breathing machine pipeline. VAP is the concurrent lung parenchymal infection of patients after receiving mechanical ventilation for 48 hours, and the incidence rate of VAP is reported to be 20-50% in domestic and foreign documents. It often results in prolonged patient hospitalization and increased patient mortality. Therefore, taking effective measures to enhance the management of the condensate is significant in reducing the occurrence of VAP.

Besides basic air inlet and outlet pipelines, the breathing machine pipeline also comprises a Y-shaped pipe and a water collecting cup, wherein the water collecting cup at the lower end of the Y-shaped pipe is mainly used for receiving condensed water. The condensed water is formed by the condensation of the humid heat gas of the respiratory tract of a patient, possibly contains pathogenic substances such as bacteria and the like, particularly the condensed water generated in the heating and humidifying process of highly infectious respiratory diseases (such as SARS, tuberculosis and the like), and belongs to highly dangerous medical waste. On the other hand, the capacity of the water collecting cup is usually designed to be small, so that nursing staff are often required to take down the water collecting cup before the water collecting cup is fully collected, condensed water in the water collecting cup is poured out and is continuously connected back to the Y-shaped pipe for use, frequent replacement not only increases the infection chance, but also causes very heavy workload for the nursing staff. When the condensed water in the water collecting cup is excessively accumulated, the condensed water flows back to enter a breathing machine pipeline to cause the cavity of the breathing machine to be narrow, the resistance of an air passage is increased, and therefore the breathing work of a patient is increased, and the tidal volume is reduced. The ventilator frequently prompts high-pressure alarm when the condensate water flows back slightly, and the condensate water enters the lower respiratory tract of a patient along with the air flow when the condensate water flows back heavily, so that VAP infection occurs.

Therefore, the novel water collecting cup which can structurally avoid the backflow of condensed water in the water collecting cup to a breathing machine pipeline and automatically conduct closed drainage on the condensed water is particularly important for solving the problems of backflow caused by the condensed water and air pollution caused in the pouring process.
