Description

Pleural cavity drainage system

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a pleural cavity drainage system.

Background

The closed thoracic drainage technology is widely applied to thoracic drainage after hemothorax, pneumothorax, empyema and thoracotomy as a treatment means, and plays an important role in treating diseases. In order to promote the rapid recovery of patients with pleural pneumatosis and hydrops and achieve the purpose of reestablishing negative pressure in the thoracic cavity in a shorter time, the negative pressure suction is often needed to enhance the drainage effect. The currently clinically common pleural cavity drainage system only comprises a drainage bottle without a fixing device, and is generally directly placed on the ground, and because the drainage bottle is made of a lighter material, the drainage bottle is easy to incline or carelessly knocked down in clinical application, artificial pneumothorax can be caused, serious people even pipeline is separated, and the safety of a patient is threatened; the drainage bottle which is clinically and conventionally used at present is usually internally provided with a physiological sodium chloride solution for regulating the air pressure of a bottle cavity, the physiological sodium chloride solution needs to be manually injected into a proper amount by a nurse, and the function of regulating the air pressure cannot be exerted if too much or too little; meanwhile, the drainage bottle has the function of collecting pleural effusion, a nurse needs to observe and record the drainage amount every shift, but the nurse needs to mark the current scale on the liquid level of the liquid collection bottle because the liquid in the liquid collection bottle cannot be poured out, so that the drainage amount can be accurately calculated in the next shift; in addition, the pleural effusion is gathered to a certain degree and the drainage bottle needs to be replaced in time, so that medical staff is often required to observe the pleural effusion at any time. Because the position of the closed thoracic drainage bottle needs to be lower than the drainage port by at least 60cm, the sight of medical personnel is difficult to keep horizontal with the liquid level, the observation is very inconvenient, and the accuracy of measurement is influenced by visual errors. When the patient is more, the time shift medical personnel are less at night, and the workload of the nurse is greatly increased by observing, marking, calculating and recording the drainage quantity, so that the nursing efficiency is reduced, the mark scale is easy to miss, the drainage quantity calculation error is wrong, great potential risks are brought to the patient, the treatment of the patient is delayed, and the medical dispute is caused.
