Cardiothoracic surgical closed nursing drainage device

Abstract

The invention discloses a cardiothoracic surgical closed nursing drainage device which comprises a liquid storage bottle. A sealing cover is arranged on the upper surface of the liquid storage bottle,an exhaust tube and a connecting tube are arranged on the upper surface of the sealing cover, an inspiration tube is arranged inside the exhaust tube, an inspiration barrel is arranged at the end, which is far away from the exhaust tube, of the inspiration tube, a rubber plug is arranged inside the inspiration barrel, the outer side surface of the rubber plug is in contact with the inner side surface of the inspiration barrel, a push handle is arranged on the rear surface of the rubber plug, and a push plate is arranged at the end, which is far away from the rubber plug, of the push handle. The cardiothoracic surgical closed nursing drainage device has the advantages that the cardiothoracic surgical closed nursing drainage device is simple in structure, can be reliably fixed and is safe and hygienic; treatment suffering can be relieved for patients to a great extent, and the cardiothoracic surgical closed nursing drainage device can bring convenience in use; the cardiothoracic surgical closed nursing drainage device can be adhered on the skin of the patients without adhesive tapes, and accordingly skin allergy of the patients can be completely eradicated; a first air bag can be pinched, accordingly, air in the first air bag can be delivered into a second air bag via an air inlet tube, and a drainage tube can be conveniently fixed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a closed nursing drainage device for cardiothoracic surgery. Background technique [0002] In clinical practice, the central venous catheter is used as a closed chest drainage catheter. Because the patient's pleural effusion needs to be injected with medicine, or the pleural fluid sample in the drainage tube is sampled, all of these need to be disconnected from the drainage catheter and the drainage bag interface to perform the above The operation destroys the sealing of the drainage system, which is likely to cause pleural effusion leakage, bacteria retrograde causing chest infection, etc., and the operation is inconvenient. At the same time, it aggravates the pain of catheter drainage for patients, increases the risk of nosocomial infection and the economic burden of patients. Existing drainage devices are directly pasted on the patient's skin through adhesive tape, and...

Problems solved by technology

[0002] In clinical practice, the central venous catheter is used as a closed chest drainage catheter. Because the patient's pleural effusion needs to be injected with medicine, or the pleural fluid sample in the drainage tube is sampled, all of these need to be disconnected from the drainage catheter and the drainage bag interface to perform the above The operation destroys the sealing of the drainage system, which is easy to cause pleural effusion leakage, bacteria retrograde and cause chest infection, etc. The operation is inconvenient, and at the same time, it aggravates the pain of catheter drainage for patients, increases the risk of nosocomial infection and the economic burden of patients

The existing drainage device is directly pasted on the patient's skin with adhesive tape. Long-term use will easily cause skin allergies, increase the patient's discomfort, and bring more treatment pain to the patient.
