Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to an anti-blocking dredger for medical drainage tubes. Background Art
[0002] Drainage tubes are a kind of medical device used for clinical surgical drainage. They guide the pus, blood, and liquid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used clinically, some are used for urinary catheterization, some are used for wounds, and they are used in the chest cavity, brain cavity, gastrointestinal tract, bile duct, etc. The purpose of surgical drainage is to guide the pus, blood, and liquid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and affect wound healing. During the use of the drainage tube, the inner wall of the tube may be blocked due to the discharged liquid, so it is necessary to use an anti-blocking dredger to clear the inside of the tube so that the drainage tube can work normally.
[0003] When drainage tubes are blocked, they are usually unblocked by normal saline injection, but this usually fails. Even if they are successfully unblocked, the tubes may soon become blocked again due to incomplete unblocking, and ultimately the tubes have to be replaced, causing economic burden, trauma, and psychological pressure on the patients. Therefore, in order to solve the aforementioned problems, we propose an anti-blockage unblocker for medical drainage tubes. Utility Model Content

DETAILED DESCRIPTION
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;
[0022] Reference Figure 1-3 , an anti-blocking dredger for medical drainage tubes, comprising a conveying box 1 and a dredging soft rod 4, the front end of the dredging soft rod 4 is conical, and a dredging thread 5 is fixedly installed on the front side of the outer surface of the dredging soft rod 4; a plurality of barbs 6 are fixedly installed on the outer surface of the conical front end of the dredging soft rod 4 at equal intervals, and the rear ends of the plurality of barbs 6 and the front end of the dredging soft rod 4 are both cambered structures. The conveying box 1 is sleeved on the outer surface of the dredging soft rod 4, and the conveying box 1 is transmission-connected with the dredging soft rod 4. A moving mechanism and a rotating mechanism for moving and rotating the dredging soft rod 4 are installed inside the conveying box 1, and the rotating mechanism is transmission-connected with the moving mechanism; a motor 3 and a control button 2 are fixedly installed on the back of the conveying box 1, and a control circuit board 7 is fixedly installed on the inner wall of the conveying box 1, and the control button 2 and the motor 3 are both electrically connected with the control circuit board 7, and the motor 3 is transmission-connected with the rotating mechanism.
[0023] When the drainage tube needs to be unblocked, the front end of the unblocking soft rod 4 can be inserted into the drainage tube, and the conveying box 1 can be connected to an external power supply, and the motor 3 can be started by the control button 2. The motor 3 drives the unblocking soft rod 4 to rotate forward through the rotating mechanism and the moving mechanism. The unblocking soft rod 4 can break the blockage in the drainage tube through the front end barb 6 and the unblocking thread 5, so that it cannot block the drainage tube. Finally, the unblocking soft rod 4 can be pulled out and disinfected. The barb 6 can hook out the blockage when the unblocking soft rod 4 is pulled out from the drainage tube to prevent the blockage from continuing to remain in the drainage tube.
[0024] The moving mechanism is composed of a rotating shaft 8, two moving wheels 9, a worm gear 10 and a first mounting frame 11. The first mounting frame 11 is fixedly mounted at the bottom of the inner side of the conveying box 1. The rotating shaft 8 is rotatably mounted between the left and right sides of the conveying box 1. The outer surface of the rotating shaft 8 is fixedly mounted with a worm gear 10 and a moving wheel 9. Another moving wheel 9 is rotatably mounted inside the first mounting frame 11. The two moving wheels 9 are respectively located at the upper and lower sides of the dredging soft rod 4. The rotating mechanism is composed of a worm 12, a second mounting frame 13 and two rotating wheels 14. The worm 12 is rotatably mounted between the front and rear sides of the conveying box 1. The second mounting frame 13 is fixedly mounted on the right side of the conveying box 1. A rotating wheel 14 is fixedly mounted on the outer surface of the worm 12. Another rotating wheel 14 is rotatably mounted inside the second mounting frame 13. The two rotating wheels 14 are respectively located at the left and right sides of the dredging soft rod 4. The worm 12 is meshedly connected with the worm gear 10, and one end of the worm 12 is fixedly connected to the output end of the motor 3. The side surfaces of the two rotating wheels 14 and the two moving wheels 9 are equidistantly mounted with multiple rollers 15 for circumferential rotation. The axes of the rollers 15 mounted on the side surfaces of the rotating wheels 14 are perpendicular to the axis of the rotating wheels 14, and the axes of the rollers 15 mounted on the side surfaces of the moving wheels 9 are perpendicular to the axis of the moving wheels 9.
[0025] The motor 3 can drive the worm 12 to rotate, the worm 12 can drive the worm wheel 10 to rotate, and the worm wheel 10 can drive the rotating shaft 8 to rotate at the same time. When the worm 12 rotates, the rotating wheel 14 on the surface can rotate. One side of the rotating wheel 14 contacts the surface of the dredging soft rod 4, which can drive the dredging soft rod 4 to rotate, so that the dredging thread and the barb 6 can break the blockage inside the drainage tube.
[0026] After the rotating shaft 8 rotates, it can drive the forward wheel 9 to rotate. One side of the forward wheel 9 contacts the surface of the dredging soft rod 4, which can drive the dredging soft rod 4 forward, so that the dredging soft rod 4 can continuously enter the interior of the drainage tube.
[0027] When the dredging soft rod 4 rotates, the roller 15 on the surface of the moving wheel 9 will rotate along with the dredging soft rod 4, reducing the friction between the dredging soft rod 4 and the moving wheel 9. Similarly, when the dredging soft rod 4 moves forward, the roller 15 on the surface of the rotating wheel 14 rotates under the action of the dredging soft rod 4, reducing the friction between the dredging soft rod 4 and the rotating wheel 14.
