Portable self-negative pressure chest drainage bottle

Abstract

The invention discloses a portable self-negative pressure chest drainage bottle. A liquid collecting chamber, a water sealing chamber, a pressure adjusting chamber and a power chamber are arranged; air liquid is drained into the liquid collecting chamber through a draining pipe; air in the air liquid successively passes through an air guide pipe, the water sealing chamber and the pressure adjusting chamber and then enters an exhaust pipe; under the driving of power, air in the exhaust pipe is timely drained to the exterior. The drainage bottle can generate negative pressure and can adjust the magnitude of the negative pressure, is beneficial to draining pneumatosis and hydrops in the chest of a patient, is beneficial to reconstruction of negative pressure in the chest within shorter period of time, is beneficial to quick rehabilitation of the patient, is portable and is beneficial to the off-bed action of the patient at early period.

Description

technical field [0001] The invention belongs to the technical field of medical device design, and in particular relates to a portable self-negative pressure chest drainage bottle. Background technique [0002] After thoracotomy, due to the huge cavity remaining in the thoracic cavity after organ resection, the pressure in the thoracic cavity increases. In order to rebuild the negative pressure environment in the thoracic cavity, it is necessary to create negative pressure in the thoracic cavity by breathing, coughing and exhausting after the thoracotomy. , restore the preoperative negative pressure in the thoracic cavity, and promote the recruitment of the remaining lung. [0003] In the prior art, in order to solve the problem of pleural exhaust and drainage, a chest drainage bottle came into being. Closed chest drainage is to put one end of the drainage tube into the chest cavity, and the other end is connected to a water-sealed bottle lower than its position. In order to...

Problems solved by technology

[0004] However, the structure of the existing thoracic drainage bottle is too simple, and the patient needs to stay in bed for a long time after the operation. The drainage bottle is usually placed under the bed, which is not conducive to getting out of bed as soon as possible after the operation, and the recovery is slow, which increases the recovery cost of the patient.

Moreover, the existing chest bottle needs to be connected to the central negative pressure pole or connected to the negative pressure drainage machine pole to achieve negative pressure state. Once the negative pressure device is connected, the patient will not be able to get out of bed, which will affect the early recovery of the patient.
