Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a chest tube pericardium and mediastinum pipeline squeezer. Background Art

[0002] In thoracic surgery, chest drainage tubes are widely used in lung resection, heart surgery, etc. to drain postoperative pleural effusion and gas and maintain the normal emptying state of the chest cavity. In chest trauma, chest drainage tubes are used to drain blood, gas or other secretions in the chest cavity, relieve chest pressure, and avoid chest infection and chest abscess. In the treatment of chest infection, chest drainage tubes can effectively drain pus and secretions in the chest cavity and promote the removal and healing of infection foci. In closed chest drainage, chest drainage tubes can continuously and effectively drain pleural effusion through a negative pressure drainage system to maintain normal chest pressure and promote recovery. When chest drainage tubes or pericardial and mediastinal tubes are used for drainage, the discharged drainage fluid or effusion may contain blood clots or pus, which may easily lead to pipeline blockage and reduce the drainage effect. At present, manual squeezing is used to slowly squeeze the blocked part toward the outlet, which is not only inefficient, but also increases the workload of medical staff. Utility Model Content

[0025] Example

[0026] See also Figure 1-3The utility model provides a technical solution of a chest drainage tube pericardium and mediastinum pipeline squeezer: it includes a squeezing box 1, and the two ends of one side of the squeezing box 1 are respectively provided with an inlet 2 and an outlet 3 for inserting and exiting the pipeline. A squeezing mechanism 4 for squeezing the pipeline is installed on the squeezing box 1, and the squeezing mechanism 4 includes a pressing rotating shaft 41, a plurality of connecting rods 42 and a squeezing ball 43. The pressing rotating shaft 41 is rotatably installed on the upper end of the squeezing box 1, and the connecting rod 42 is fixed to the lower end of the pressing rotating shaft 41 and is located inside the squeezing box 1. The other end of the connecting rod 42 away from the pressing rotating shaft 41 is rotatably connected to the squeezing ball 43. After the pipeline passes through the squeezing box 1, the pressing rotating shaft 41 is rotated downward, and the pressing rotating shaft 41 drives the connecting rod 42 to move downward and rotate, so that the squeezing ball 43 squeezes the pipeline, and at the same time, the squeezing ball 43 rotates around the pressing rotating shaft 41, and the drainage fluid inside the squeezing pipeline flows in one direction.

[0027] The extrusion box 1 includes a lower box body 101 and an upper box body 102. The upper end of the lower box body 101 is connected to the upper box body 102. A pipeline groove 1011 for placing the pipeline is opened inside the lower box body 101. The pipe inlet 2 and the pipe outlet 3 are formed by splicing the semicircular grooves of the lower box body 101 and the upper box body 102. The upper box body 102 is provided with a through hole matching the pressing rotating shaft 41. When the pipeline is extruded, the lower box body 101 and the upper box body 102 are first opened, and then one end of the pipeline is placed in the pipeline groove 1011, and the two ends are respectively passed through the pipe inlet 2 and the pipe outlet 3, and then the lower box body 101 and the upper box body 102 are spliced ​​together.

[0028] A rotating handle 5 is installed at the upper end of the pressing rotating shaft 41. The length of the rotating handle 5 is ≥ the radius of the squeezing box 1. The pressing rotating shaft 41 can be rotated better by rotating the handle 5. The rotating handle 5 has a certain length, which is more labor-saving.

[0029] An arc-shaped support pad is installed at the bottom of the pipeline groove 1011 on the lower box body 101. The arc-shaped support pad is made of soft material and can better place the pipeline.

[0030] A spring 6 is installed at the upper end of the lower box body 101 to ensure that the pressing rotating shaft 41 can automatically move upward without squeezing the pipeline without the action of external force, thereby ensuring the normal flow of the drainage fluid in the pipeline.

[0031] The lower box body 101 and the upper box body 102 are connected by threading or snapping together through a snap-fit ​​slot, so as to facilitate the assembly and disassembly of the lower box body 101 and the upper box body 102 .

[0032] Semicircular tubes 7 are fixed on the semicircular grooves of the lower box body 101 and the upper box body 102. Friction blocks 8 are installed on the inner walls of the semicircular tubes 7 to prevent the pipeline from moving, thereby increasing the friction of the pipeline at the inlet 2 and the outlet 3 to prevent the pipeline from moving during the rotation and extrusion process.

[0033] When the device is in use, first open the lower box body 101 and the upper box body 102, then put one end of the pipeline into the pipeline groove 1011, and the two ends pass through the inlet 2 and the outlet 3 respectively, and then splice the lower box body 101 and the upper box body 102 together, rotate the pressing rotation shaft 41 downward, and the pressing rotation shaft 41 drives the connecting rod 42 to move downward and rotate, so that the squeezing ball 43 squeezes the pipeline, and at the same time, the squeezing ball 43 rotates around the pressing rotation shaft 41, squeezing the drainage fluid inside the pipeline to flow in one direction. When squeezing drainage is not required, no external force is required, and the spring 6 pushes the pressing rotation shaft 41 upward to ensure the normal flow of the drainage fluid in the pipeline. The device can continuously circulate and effectively squeeze the drainage fluid in one direction to prevent the drainage fluid from flowing back and clogging, thereby improving the drainage effect. In addition, the operation of medical staff is quick and convenient, and the placement and removal of the pipeline are simple and convenient, which is more in line with actual use needs.
