Anhydrous noiseless chest closed drainage device

Abstract

The invention discloses an anhydrous noiseless chest closed drainage device which comprises a drainage pipe, wherein a fixing rubber belt is arranged at the left end of the drainage pipe; the right end of the drainage pipe is connected with a vacuum liquid storage tank through a drainage opening; a one-way valve is arranged on the drainage pipe; a pressure adjusting valve is arranged at the right end of the one-way valve; a hydrometer is arranged at the right end of the pressure adjusting valve; a switch knob is arranged at the right end of the hydrometer; a vacuum air exhausting pipe is arranged at the right end of the vacuum liquid storage tank; a closing switch is arranged on the vacuum air exhausting pipe; a liquid outlet door is hinged to the lower end of the vacuum liquid storage tank through a hinge. The chest closed drainage device adopts the anhydrous drainage device, the condition that frequent replacement is needed in traditional saline water or cold water drainage is avoided, the drainage speed can be automatically adjusted according to feedback pressure difference in a pressure adjusting pipe by a current-limiting device, and when the pressure difference is zero, the drainage can be automatically stopped, so that the nursing workload can be relieved, the use convenience of the drainage device is improved, and the popularization and generalization are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anhydrous silent thoracic closed drainage device. Background technique [0002] Closed thoracic drainage is a common method for treating pneumothorax. Most of the existing drainage devices are normal pressure or continuous negative pressure water sealing drainage method, but it requires continuous power to maintain normal pressure or negative pressure, which will generate loud noise and seriously affect The patient's rest condition, and the saline or cold water needs to be replaced frequently, which greatly increases the nursing workload. For this reason, we propose a waterless and silent thoracic closed drainage device. Contents of the invention [0003] The object of the present invention is to provide a waterless and silent closed chest drainage device to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the abov...
