Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a chest drainage device. Background Art

[0002] The human chest cavity is a negative pressure cavity. Once the chest cavity is connected to the outside world (such as thoracotomy, chest wall knife stab, pneumothorax, etc.), the outside gas pressure is higher than the pressure in the chest cavity, and the lungs will be compressed rapidly. At this time, it is necessary to repair the connecting parts of the chest wall or lungs, and place a negative pressure drainage tube in the chest cavity to discharge the gas in the chest cavity and rebuild the negative pressure in the chest cavity. At this time, a chest negative pressure drainage device is required.

[0003] The current chest drainage devices are large and heavy, which causes a lot of inconvenience to medical workers in carrying patients. At the same time, it is also extremely inconvenient for patients to get out of bed and move around in the early stage, which is not conducive to the early recovery of patients. In addition, the existing drainage devices are inconvenient to take samples, and the negative pressure inside the device cannot be kept stable during sampling. In addition, due to the closure of the chest cavity during use, the above-mentioned devices cannot monitor the chest cavity environment and the gas conditions of the drainage device in a timely and effective manner, which affects the medical staff's judgment of the condition.
