Description

Technical Field

[0001] The utility model relates to the technical field of drainage tube fixing, in particular to a drainage tube fixing device for pleural effusion. Background Art

[0002] Pleural effusion is a common clinical symptom characterized by pathological fluid accumulation in the pleural cavity. The pleural cavity is a potential gap between the visceral and parietal pleura. There are 5 to 15 ml of fluid in the pleural cavity of a normal person, which acts as a lubricant during respiratory movement. 500 to 1000 ml of fluid is formed and absorbed in the pleural cavity every day. Pleural effusion can occur if any reason causes increased production or decreased absorption of fluid in the pleural cavity. According to its occurrence mechanism, it can be divided into two types: transudative pleural effusion and exudative pleural effusion. The direct treatment for pleural effusion is to use a drainage tube to drain the effusion.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides a technical solution: a drainage tube fixing device for pleural effusion, comprising a connecting tube 1 and a drainage hose body 6, one end of the drainage hose body 6 is fixedly connected with a sealing piston 12, one end of the connecting tube 1 is fixedly connected with a sealing piston 12, the sealing piston 12 is clamped with a connecting sleeve 10, a fixing sleeve 2 is provided on the outside of the drainage hose body 6, a suction cup 9 is provided on the bottom of the fixing sleeve 2, a threaded ring 11 is threadedly connected to the outside of the connecting sleeve 10, pins 14 are equidistantly inserted on the outside of the connecting sleeve 10, a limiting ring 16 is slidably connected to the outside of the limiting ring 16, a connecting pressure plate 17 is fixedly connected to the outside of the connecting pressure plate 17, and a No. 1 spring 15 and a No. 2 spring 18 are fixedly connected to the inside of the connecting pressure plate 17.

[0020] It can be understood that the utility model fixes the fixing sleeve 2 at a specified position by providing a suction cup 9. According to specific usage conditions, after adjusting the drainage hose body 6 to a specified length, the fastening screw 5 is rotated to fix the drainage hose body 6 by the pressure plate 4 at the bottom of the fastening screw 5. When the connecting pipe 1 and the drainage hose body 6 need to be connected, the sealing piston 12 is inserted into the connecting sleeve 10. When the pin 14 is located at the limiting groove 13, under the action of the connecting pressure plate 17, the pin 14 is inserted into the limiting groove 13, and then the threaded ring 11 is rotated to squeeze the pin 14 through the threaded ring 11, so that the pin 14 is stuck in the limiting groove 13.

[0021] See also Figure 1-3 The outer side of the sealing piston 12 is provided with a limiting groove 13 which cooperates with the latch 14, and one end of the latch 14 is a slope structure.

[0022] It can be understood that the latch pin 14 of the utility model is configured as an inclined structure, which facilitates the threaded ring 11 to squeeze the latch pin 14, thereby pressing and locking the latch pin 14 in the limiting groove 13 to prevent the sealing piston 12 and the connecting sleeve 10 from separating.
