Description

TECHNICAL FIELD

[0001] The utility model relates to a punching device technical field, specifically relates to a punching device for thoracic and abdominal cavity drainage bag. BACKGROUND

[0002] Hydrothorax and ascites are common pathological phenomena in clinic. Hydrothorax is actually pleural effusion. The pleural cavity is a closed interstice composed of visceral pleura and parietal pleura. A small amount of liquid exists in the pleural cavity of normal people to play a lubricating role. When the parietal pleura produces too much hydrothorax or the visceral pleura absorbs hydrothorax at a slower speed due to some reasons such as inflammation and tumor, the liquid in the thoracic cavity increases, thereby forming hydrothorax. Ascites is mainly related to the imbalance of liquid exchange between the body and the outside, the imbalance of liquid exchange in and outside the blood vessels, and various malignant tumors. When the liquid in the abdominal cavity increases, ascites is formed.

[0003] In actual clinic, it is not appropriate to drain the hydrothorax and ascites too fast or in large quantities. When draining the hydrothorax, if the hydrothorax is drained too fast or in large quantities, it may cause reexpansion pulmonary edema, pleural reaction and insufficient blood supply to the heart and brain. When draining the ascites, if the ascites is drained too fast or in large quantities, it may cause electrolyte imbalance, hepatic encephalopathy and insufficient blood supply to the heart and brain. When draining the hydrothorax and ascites of the patient, a drainage bag is usually connected to the other end of the thoracic and abdominal cavity tube to collect the drained hydrothorax and ascites. In order to prevent the hydrothorax and ascites from being drained too fast or in large quantities, the inventor designs an automatic drainage cutoff device to avoid the above-mentioned situations. However, the problem is that the water level sensing contact needs to be inserted into the drainage bag when the automatic drainage cutoff device is used, so the drainage bag needs to be perforated during installation.
