Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a novel three-lumen two-balloon gravity traction device. Background Technology

[0002] The three-lumen two-balloon tube consists of a three-lumen tube, a gastric balloon, and an esophageal balloon. The gastric and esophageal balloons are attached to one end of the three-lumen tube. The three-lumen tube is composed of a semi-circular cross-section and two quarter-circular cross-sections. The gastric balloon catheter and the esophageal balloon catheter are respectively inserted into the quarter-circular cross-sections. The three-lumen two-balloon tube is used for emergency compression hemostasis when the esophageal or gastric fundus veins rupture and bleed.

[0003] A search revealed that application number CN202121949085.X discloses a three-lumen, two-bladder tube gravity traction device, which includes a base, a height adjustment structure, a horizontal adjustment structure, and a traction assembly. The height adjustment structure is disposed on the upper end face of the base and is fixedly connected to the base. The horizontal adjustment structure is disposed on the upper end of the height adjustment structure and is movably connected to the height adjustment structure. The traction assembly includes a traction rope, a traction ring, and a spool. One end of the traction rope is integrally connected to the traction ring, and the other end is fixedly connected to the spool. The traction rope is wound around the spool. The traction ring is combined and connected to the outer end of the three-lumen, two-bladder tube. A connection structure for fixing the spool is provided.

[0004] In the prior art, a gravity traction device for a three-lumen two-bladder tube is used. Although the height and horizontal position of the traction component can be adjusted, the operation of fixing the three-lumen two-bladder tube with the traction rope through the traction ring is cumbersome and the fixing effect is not ideal, which can easily lead to the tube falling off.

[0005] Therefore, we propose a novel three-chamber, two-bladder gravity traction device. Utility Model Content

A pressure block is fixedly connected to the end of the multiple elastic plates away from the threaded tube. A threaded ring is threadedly connected to the outer wall of the threaded tube, and a fixing assembly is mounted on the threaded ring. The fixing assembly includes a moving ring and a squeezing ring, and a weight is fixedly connected to the other end of the traction rope.

[0010] As a preferred technical solution of this utility model, the multiple elastic plates and multiple pressure blocks are arranged in a ring around the three-lumen two-bladder tube, and each pressure block is fixedly connected to a rubber pad on the side close to the three-lumen two-bladder tube.

[0011] As a preferred technical solution of this utility model, the end of the moving ring near the traction rope is rotatably connected to the threaded ring, the compression ring has a conical structure, and the end of the compression ring away from the three-cavity two-bladder tube is fixedly connected to the moving ring.

[0013] This invention provides a novel three-lumen, two-bladder gravity traction device. It has the following advantages:

[0014] 1. This novel three-lumen two-bladder tube gravity traction device involves inserting the three-lumen two-bladder tube into a threaded tube during use. Then, by rotating the threaded ring, it moves along the threaded tube towards the three-lumen two-bladder tube. As the threaded ring moves, the moving ring and the squeezing ring also move backward synchronously. At this time, multiple pressure blocks contract inward under the squeezing ring, tightly pressing the three-lumen two-bladder tube. The operation is simple and convenient, and the three-lumen two-bladder tube is not easy to detach when subjected to external force. The other end of the traction rope is tied with a weight, and the traction rope is supported and balanced by a rotating wheel.

[0015] 2. This novel three-lumen two-balloon gravity traction device, when in use, involves turning the handwheel, which drives the threaded rod to rotate, thereby raising and lowering the lifting plate. The raising and lowering of the lifting plate causes the lifting rod to move up and down, thus allowing the height of the traction rope to be adjusted to find the most suitable traction angle and achieve the best traction effect. Through the setting of the clamping seat, pressure plate and threaded hand rod, the device can be fixed in any different position on both sides of the hospital bed, increasing the practicality of the device.

The lifting rod 12 has an L-shaped structure, and the top end of the lifting rod 12 penetrates the frame body 10 and is slidably connected to the frame body 10.

A rotating shaft 17 is rotatably connected between the inner walls of the two sides of the wheel frame 16. The rotating wheel 18 is fixedly sleeved on the outer wall of the rotating shaft 17. Multiple elastic plates 21 and multiple pressure blocks 22 are arranged in a ring around the three-cavity two-bladder tube, and a rubber pad 23 is fixedly connected to the side of each pressure block 22 closest to the three-cavity two-bladder tube.

[0025] In use, turning the handwheel 14 causes the threaded rod 13 to rotate, which in turn causes the lifting plate 11 to rise and fall. The rising and falling of the lifting plate 11 causes the lifting rod 12 to move up and down, thereby adjusting the height of the traction rope 19 to find the most suitable traction angle and achieve the best traction effect. With the setting of the clamping seat 27, pressure plate 28 and threaded hand rod 29, the device can be fixed in any different position on both sides of the hospital bed, increasing the practicality of the device.
