Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically to a medical drainage tube extrusion device. Background Art

[0002] With the continuous advancement of science and technology, medical equipment is becoming more and more rigorous and intelligent. In order to ensure the progress of intubation and other operations, drainage is required through drainage tubes. When using drainage tubes, a medical drainage tube extrusion device is required. The medical drainage tube extrusion device is a device that clears the blocked material inside the drainage tube at one end. The medical drainage tube extrusion device is mainly composed of a shell component, a connecting component, an extrusion component and a movable groove component. The medical drainage tube extrusion device has the advantages of a wide range of applications and good extrusion effect.

[0003] Common medical drainage tube extrusion devices generally have the following defects during use:

[0004] First, during the use of common medical drainage tube extrusion devices, the drainage tube needs to be connected to the collector before extrusion. Before the connection, since the drainage tube is exposed to the outside air, there are bacteria in the outside environment, which can easily contaminate the drainage tube and cause harm to the patient.

[0005] Second, during the use of common medical drainage tube extrusion devices, when the outside temperature is low, the liquid inside the drainage tube will condense, causing blockage, etc., thereby blocking the connection between the drainage tube and the collector. The liquid inside the drainage tube cannot enter the collector, which is not conducive to the use of the drainage tube;

[0006] Third, during the use of common medical drainage tube extrusion devices, residual tissue and other substances may exist inside the drainage tube, thus blocking the drainage tube. It is necessary to squeeze it through an extrusion tube. Generally, manual hand-held gauze is used for squeezing, which is complicated to operate. After the squeezing is completed, the gauze is directly discarded, resulting in a waste of resources.

[0007] To sum up: during the use of common medical drainage tube extrusion devices, the drainage tube is exposed to the outside air. The presence of pathogens in the external environment can easily cause contamination of the drainage tube, and the liquid inside the drainage tube will condense, thereby causing blockage, etc., thereby blocking the connection between the drainage tube and the collector. The liquid inside the drainage tube cannot enter the collector and is generally squeezed by manually holding gauze, which is more complicated to operate.
