Description
Technical Field
The invention relates to the field of medical equipment, and is used for collecting condensed water in a breathing machine pipeline.
Background
The correct collection of the condensed water in the pipeline of the breathing machine is a key link for reducing the backflow of the condensed water, ensuring the ventilation effect of a patient, reducing the incidence rate of relevant pneumonia of the breathing machine and reducing the infection risk of nursing staff. The production of condensed water comprises two parts: (1) and condensing water vapor in the air supply pipeline of the respirator. Because a certain distance is reserved between the artificial air passage and the humidifying tank, liquid is formed in the pipeline due to the fact that the room temperature is relatively low before the heated and humidified air is sent into the air passage of the patient, and therefore water is formed in the pipeline. (2) The patient exhales, i.e., water vapor in the ventilator circuit condenses. Machine for workingDuring mechanical ventilation, the temperature of the gas in the alveoli is 37 ℃ (the saturated water vapor pressure is 47mm Hg, and 1mm Hg is 0.133k Pa), the temperature is reduced to about 20 ℃ when the patient is exhaled to the outside (the saturated water vapor pressure is 20mm Hg), and the excessive moisture is aggregated in the breathing machine pipeline to form condensed water. And the condensed water is mainly generated because the respiratory tract gas of the patient is condensed on the tube wall and is gradually kept in the respiratory tube, so that a certain amount of pathogenic bacteria exist in the condensed water. Traditional comdenstion water collection device connects the cup that catchments for Y type tee bend interface down, catchments the cup position and is less than humidifier and patient's gas channel mouth level, and the nursing staff empties cool comdenstion water according to the water level in the cup that catchments. Therefore, nursing staff need to pay special attention to adjust the breathing machine pipeline and enable the water collecting cup to be in a vertical state, and accumulation of condensed water in the breathing machine pipeline is reduced. Multiple researches show that the condensed water in the breathing machine pipeline and the water collecting cup is an important place for bacterial reproduction, the bacteria detection positive rate of the condensed water is 71.43-85.71%, and the bacteria count in the condensed water can reach 105cfu/mLt. The forming speed of the condensed water can reach 20-40ml/h, and the longer the breathing machine pipeline is, the more the cool condensed water is generated. In addition, the inner diameter of the pipeline can be reduced by the condensed water in the pipeline of the breathing machine, so that the resistance of the airway is increased, the inspiratory work of a patient is increased, and the tidal volume is reduced; meanwhile, liquid moves along with airflow, so that the respirator is easy to trigger mistakenly, the ventilation frequency rises, and iatrogenic injury is caused, and therefore, condensed water must be poured in time. Untimely dumping can cause the condensed water containing bacteria to directly flow back into the airway, which is very easy to cause Ventilator Associated Pneumonia (VAP). Most researches show that the incidence rate of VAP is in positive correlation with the accumulation of condensate water in the pipeline and the backflow rate of the condensate water, and the condensate water is one of high-risk factors of the VAP. Managing and processing the condensed water can reduce or prevent the occurrence of VAP, wherein timely pouring of the condensed water within the water collection cup is one of the most important influencing factors for preventing the occurrence of VAP.
The common treatment method for nursing staff in clinic comprises the steps of observing the water level height in the water collecting cup, wearing gloves, manually detaching the water collecting cup, pouring a plastic bucket with a cover to collect condensed water, and connecting the water collecting cup below a Y-shaped three-way connector of a respirator. In the operation process, the condensed water is exposed in the air, so that the environment is polluted, and the exposure risk of medical personnel is increased. And the patient needs to be dumped for 1 time in 1-3 hours generally according to the application states of the breathing machine, humidification and the like, and the workload is extremely large; if the condensed water is not poured in time, the condensed water can be accumulated, the risk of related pneumonia of a respirator is increased, and the inner diameter of a pipeline is reduced, so that the airway resistance is increased (the tube diameter is reduced by 1 time, the airway resistance is increased by 6 times), ventilation is affected, and suffocation can be caused in serious cases. When the water collecting bottle is opened improperly (such as position deviation and the like), air pressure fluctuation in the breathing machine pipeline can be caused, a patient is choked to have a cough reflex, and secretion of the breathing machine pipeline can pollute the whole breathing machine pipeline.
Therefore, the existing water collecting cup collecting device for the breathing machine pipeline condensed water needs to observe the liquid level height of the condensed water in the water collecting cup for many times, and the workload of nursing staff is increased; when the medical staff is poured, the water collecting cup needs to be opened, the condensate is exposed in the air, and the possibility of scattering, improper treatment and the like exists, so that the risk of infection of the medical staff is increased; and the liquid accumulation condition in the pipeline of the respirator cannot be monitored and cannot be processed in time.
In the prior art, a water collecting cup is connected with a water collecting tank through a water pipe by an air pressure balance structure, so that the problem of multiple dumping (such as CN 209916968U) is avoided; a collection device (such as CN 109893735A) which is externally connected with a drainage bag and controls the upper and lower pipelines not to be opened at the same time through a linkage structure of a built-in valve body and a valve core; there is a pre-warning device (e.g. CN 210301969U) for monitoring the water level change inside the water collecting cup by an infrared sensor. However, the problem that accumulated liquid in a breathing machine pipeline cannot be monitored and timely treated, the problem that the water collecting device is exposed when being detached and the risk that the additional pipeline excessively increases a patient pipeline to break away from exist, the pipeline is complicated, bacteria breeding is increased, and nursing staff increase the management link of the breathing machine pipeline, and the difficulty of disinfection and cleaning is increased. Especially during respiratory infectious disease outbreaks, a large number of patients need to use ventilators, and medical staff is in short supply, and the prior art still has difficulty meeting the practical requirements. Therefore, the treatment of the condensate needs to be integrated in a closed manner, and the device has the functions of monitoring the accumulated liquid in the pipeline and reminding, so that the defects of the conventional clinical application device are overcome. The problem that the medical staff topples over repeatedly under the open state is solved, exposure of condensed water is reduced, the workload of the medical staff is reduced, and the working efficiency is improved. In addition, the water collecting cup is a necessary device of the respirator, and a method for pouring condensed water is needed to be improved, particularly the treatment of the condensed water when the respirator is applied to patients with respiratory infectious diseases (such as new coronary pneumonia).
