Description

Safe and effective thoracic closed drainage water seal bottle Technical Field The invention relates to the field of medical equipment, in particular to a safe and effective closed thoracic drainage water seal bottle which is suitable for treating patients needing closed drainage after pneumothorax, hydrothorax and thoracic surgery. Background If there is a lesion in the chest and lung, there will be gas or liquid in the chest, resulting in reduced lung capacity and dyspnea. The closed thoracic drainage is to suck out the gas and liquid caused by pathological changes in the thoracic cavity and recover the normal thoracic cavity by using the principle of negative pressure suction. The drainage device commonly called as a drainage bottle is commonly provided with a single cavity (only a liquid storage cavity), a double cavity (a liquid storage cavity and a water seal cavity) and three cavities (a liquid storage cavity, a water seal cavity and a display cavity), and when the existing majority of drainage bottles drain pleural effusion and gas, the drainage bottle is directly connected with a drainage negative pressure source to influence respiratory function. The patent application number 201920278624.8 is that a chest cavity closed drainage device is required to be filled with proper liquid into a safety cavity and a negative pressure cavity before being used, the required liquid amount can be achieved through multiple times of debugging, the filled liquid amount is larger, time is wasted, the liquid consumption is high, the time is very precious for a patient needing to use a drainage bottle, the pressure is relieved through a pressure regulating tube, the patient is prevented from being blocked easily when the lungs are protected from being injured by pulling by installing a one-way valve between a chest cavity drainage tube and a drainage extension tube, the sample cavity or effusion led out of the drainage extension tube connected with the sample cavity can flow back into the chest cavity of the patient during negative pressure when the lungs of the patient are inhaled, although the effusion can be prevented from flowing back to the chest cavity through installing the one-way valve between the chest cavity drainage tube and the drainage extension tube, the problem that the effusion is blocked by the one-way valve can be caused if the patient has thrombus, the water sealing bottle is lost is solved, the medical micro flow regulator on the drainage tube is also easy to block when the patient has thrombus, and meanwhile, the observation flow is very inconvenient. The patent number of China filed by the inventor is 201320560706.4, namely the safe chest closed drainage water seal bottle basically solves the technical problem that lung injury is caused by overlarge negative pressure, but when the overlarge negative pressure still exists, the bottle can only be manually treated by adopting a negative pressure release valve, and the negative pressure release valve is adopted to open, so that the atmosphere is communicated with the chest of a patient, and infection and injury can be caused. In addition, the negative pressure indicator and the water seal cavity are respectively filled with proper liquid before the water seal bottle is used, and the required liquid amount is achieved through multiple times of debugging, so that the time is very long, more liquid is required, and inconvenience is caused when the bottle is used for patients needing the drainage bottle urgently. In addition, when the negative pressure indicator reads the negative pressure value, the water cylinder of the U-shaped pipe rises along with the pressure drop, which is opposite to the habit, and the reading is not ideal. The existing water-sealed bottles are mostly single drainage tubes, share one drainage tube with gas and liquid, are inconvenient to adjust flow and negative pressure, have no negative pressure automatic protection function or require manual work and complex operation in negative pressure protection, can be used only in places with negative pressure equipment, and have the advantages that once a connecting tube connected with the negative pressure equipment is detached, the water-sealed bottles are not provided with the function of protecting patients, and can cause backflow and pulmonary infection. Therefore, the inventor considers that the emergency use can be carried out for patients, the liquid is not required to be poured into the water seal cavity and the negative pressure observation cavity before the emergency use, the required liquid quantity is small, the water seal bottle has strong treatment function, convenient operation during use, convenient observation, flow adjustment, negative pressure adjustment, convenient moving and carrying, good protection function effect, intelligent and reasonable structural design, and the water seal bottle can be used in places needing negative pressure suction and no negative pressu
