Embodiment Construction

[0027] The present invention will be described in further detail below by means of specific embodiments:

[0028] The reference signs in the drawings of the description include: connecting pipe 1, elastic gasket 2, rotating shaft 3, micro motor 4, torsion spring 5, traction rope 6, filter membrane 7.

[0029] The embodiment is basically as attached figure 1 and figure 2 Shown: the automatic decompression adjustment device of the left heart drainage tube, including a Y-shaped connecting pipe 1, the upper right branch of the connecting pipe 1 is equipped with an elastic gasket 2, a rotating shaft 3 and a micro-motor 4, and the elastic gasket 2 is made of inert metal Compared with the traditional rubber, this material avoids the rapid aging of the elastic gasket 2 caused by long-term exposure to the air; There is an opening matched with the limit column, and the elastic gasket 2 can be engaged between the two openings through the limit column. When the elastic gasket 2 needs t...

Abstract

The invention discloses an automatic decompression regulating device for a left heart drainage tube, and particularly relates to the technical field of medical equipment. The automatic decompression regulating device for the left heart drainage tube includes a Y-shaped connection pipeline, an elastic gasket, a rotating shaft and a micro motor are arranged in the connection pipeline, a hauling cable is connected between the elastic gasket and the rotating shaft, one end of the rotating shaft is connected with an output shaft of the micro motor, the micro motor is fixed outside the connection pipeline, and a first prompting lamp is arranged outside the connection pipeline. The connection pipeline is internally provided with a pressure collection module, an infrared induction module, a storage module, a processing module and a control module. According to the technical scheme, the problem that the pressure in a pipeline of an existing left heart drainage system can not be automatically regulated is solved, and the device can be used for depressurizing an extracorporeal circulation set tube in cardiac surgery.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic decompression regulating device for a left heart drainage tube. Background technique [0002] During heart surgery, it is necessary to drain the blood in the heart cavity to form a clear, bloodless surgical field of view to successfully complete the operation. A left heart drain is a drainage device placed in the left atrium or ventricle. At present, most hospitals adopt extracorporeal circulation, and implant multi-side hole pipelines through the right pulmonary vein to the left heart system to connect with the extracorporeal circulation piping system as the left heart drainage system. [0003] The negative pressure of the pipeline system of the left heart drainage system needs to be continuously adjusted with the progress of the operation. At present, most of them are adjusted manually. The timing and value of adjusting the negative pressure of the pipel...
