Description

Technical Field

[0001] This utility model relates to the field of human necessities, especially to the field of medical auxiliary equipment, and in particular to a three-lumen two-balloon traction frame. Background Technology

[0002] The three-lumen two-balloon tube is a commonly used medical device in gastroenterology, mainly used to stop acute bleeding in the esophagus and gastric fundus veins caused by portal hypertension. When in use, the three-lumen two-balloon tube is inserted into the patient's nasal cavity, and gas is injected into the gastric balloon. Then, the three-lumen two-balloon tube is pulled to achieve the effect of compression hemostasis.

[0003] In existing technologies, orthopedic floor-mounted traction pulleys are used clinically to traction the three-lumen two-balloon tube, but this method has the following drawbacks:

[0004] 1. Unlike orthopedic traction, the three-lumen two-balloon tube is placed inside the patient's body and is very sensitive and fragile. The traction device and the weight used for traction are placed outside the body during traction. When people pass by, they are very likely to touch the weight, causing the traction rope to pull the three-lumen two-balloon tube forcefully, which can cause injury to the patient.

[0005] 2. Floor-mounted traction pulleys take up space in the passageway, and are more likely to be bumped into when passing by.

[0006] 3. Traction pulleys used in orthopedics do not require high precision, and it is difficult to precisely adjust the traction height, traction angle, and traction weight. Summary of the Invention

[0007] The purpose of this utility model is to provide a three-lumen two-balloon traction frame, which aims to solve the technical problems in the prior art, such as the traction rope pulling on the three-lumen two-balloon tube and causing injury to the patient when passing by heavy objects, the traction slippage of the ground-mounted traction frame occupying space, and the low traction accuracy.

[0008] A three-cavity, two-bladder traction frame includes a tubular column with a groove at the top of one side, connecting the inner side of the column to the outside. A fixed pulley is installed within the groove, with its two ends rotatably connected to the side walls of the tubular column. The outer ring of the fixed pulley is tangent to the central axis of the tubular column. The frame also includes a traction rope, one end of which is connected to the three-cavity, two-bladder tube. The other end of the traction rope passes around the outer ring of the fixed pulley and is positioned inside the tubular column, with a fixed connection at the other end. The base has one or more weights mounted on it. The tubular column has a hatch on the side opposite to the wheel groove. One side of the hatch is hinged to the side wall of the tubular column, and the hatch has a handle. The tubular column has a slide rail near the bottom on the side of the wheel groove. One or more sliders are slidably connected to the slide rail. Each slider has a gripper and a first fastening screw. The first fastening screw is threaded to the slider, and the end of the first fastening screw abuts against the slide rail.

[0009] Furthermore, the hatch is equipped with an observation window.

[0010] Furthermore, the tubular column is equipped with an angle gauge next to the fixed pulley, and the measuring plane of the angle gauge is perpendicular to the axis of the fixed pulley.

[0011] The working principle of this utility model:

[0012] The tubular support is clamped to the upper and lower rails at the foot of the bed by two clamps. The height of the tubular support is adjusted by adjusting the position of the slider in the slide rail, which in turn adjusts the traction height of the fixed pulley. One end of the traction rope is connected to the traction end of the three-lumen two-balloon tube implanted in the patient. The other end of the traction rope is looped around the outer ring of the fixed pulley and suspended inside the tubular support. The hatch is opened, and weights are placed one by one on the bottom support of the other end of the traction rope. After adjusting to the required traction weight, the hatch is closed, and continuous traction is applied. During traction, because the weights are located inside the tubular support, they are unlikely to be touched or interfered with by passing personnel, avoiding the risk of traction injury to the patient.

[0013] Compared with existing technologies, the advantages of this invention are positive and obvious:

[0014] 1. The tubular column of this utility model conceals the weights inside the tube, preventing people from touching the weights when passing by and causing pulling injuries to the patient.

[0015] 2. The tiger's mouth clamp of this utility model can be clamped to the railing at the foot of the hospital bed, reducing the floor space occupied.

[0016] 3. The slider of this utility model can move up and down along the guide rail, thereby adjusting the height of the tubular column and thus adjusting the traction height.

[0017] 4. This utility model allows for the precise adjustment of traction weight by adding or removing weights when the hatch is opened.

[0018] 5. The angle ruler of this utility model can measure the traction angle, thereby improving the accuracy of the traction angle. Attached Figure Description

[0027] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0028] Example 1

[0029] like Figures 1 to 6As shown, this embodiment provides a three-lumen two-balloon traction frame, including a tubular column 1. In this embodiment, the tubular column 1 is a square tube column with a hollow interior. A wheel groove 104 is formed at the top of one side wall of the tubular column 1. The top of the wheel groove 104 communicates with the top opening of the tubular column 1. The inner side of the tubular column 1 communicates with the outside through the wheel groove 104. A fixed pulley 2 is installed in the wheel groove 104. A fixing plate 103 is welded to each side of the wheel groove 104. The two ends of the rotating shaft of the fixed pulley 2 are rotatably connected to the fixing plates 103 fixed to the side walls of the tubular column 1. The outer ring of the fixed pulley 2 is tangent to the central axis of the tubular column 1. It also includes a traction rope 3. One end of the traction rope 3 is connected to the traction end of the three-lumen two-balloon tube implanted in the patient. The other end of the traction rope 3 passes around the outer ring of the fixed pulley 2 and is placed inside the tubular column 1. Because the outer ring of the fixed pulley 2 is tangent to the central axis of the tubular column 1, the traction rope 3 is suspended at the center of the tubular column 1. One end of the traction rope 3 located inside the tubular column 1 is fixed to a base 301. One or more weights 7 are set on the base 301. A gap is opened on one side of the weight 7, which leads to the center of the weight 7. After the traction rope 3 is inserted into the gap, the bottom of the weight 7 is placed on the base 301 or other weights 7. The traction weight is adjusted by stacking the weights 7.

[0030] A hatch 101 is provided on the side of the tubular column 1 opposite to the wheel groove 104. The top side of the hatch 101 is hinged to the side wall of the tubular column 1. A handle 102 is provided on the hatch 101, which can be lifted upwards to open the hatch 101, making it easy to add weights 7 into the tubular column 1. A vertically elongated transparent observation window 9 is installed on the hatch 101 to facilitate observation of the number and height of the weights 7 inside the tubular column 1.

[0031] A vertical slide rail 6 is installed on one side of the tubular column 1 near the bottom of the wheel groove 104. Two sliders 4 are slidably connected to the slide rail 6. Each slider 4 is provided with a gripper 5 and a first fastening screw 401. The first fastening screw 401 is threadedly connected to the slider 4, and the end of the first fastening screw 401 abuts against the slide rail 6. After tightening the first fastening screw 401, the slider 4 can be locked in the slide rail 6, so that the slider 4 can move and be fixed along the slide rail 6, thereby adjusting the height of the slider 4, and thus adjusting the height of the tubular column 1 relative to the hospital bed, and changing the traction height. The cudgel 5 is a commonly used C-type caliper cudgel 5 in existing technology. A pressure plate 502 is provided on the inner side of the cudgel 5, and a second fastening screw 501 is threaded onto one side of the cudgel 5. The pressure plate 502 rotates to connect with the end of the second fastening screw 501. Tightening the second fastening screw 501 pushes the pressure plate 502 to clamp, thus holding the cudgel 5 to the bed foot rail, reducing the floor space occupied. Two cudgels 5 are respectively clamped onto the upper and lower rails at the foot of the bed, providing two-point fixation and making the tubular support more secure.

[0032] How to use this embodiment:

[0033] First, the tubular support column is clamped to the upper and lower rails at the foot of the bed using two thumb clamps 5. The height of the tubular support column is adjusted by adjusting the position of the slider 4 in the slide rail 6, thereby adjusting the traction height of the fixed pulley 2. Then, the traction rope 3 is set up. One end of the traction rope 3 is connected to the traction end of the three-lumen two-balloon tube implanted in the patient. The other end of the traction rope 3 is wrapped around the outer ring of the fixed pulley 2 and hangs inside the tubular support column 1. The hatch 101 is opened, and weights 7 are placed one by one on the bottom support 301 of the other end of the traction rope 3. After adjusting to the required traction weight, the hatch 101 is opened to perform continuous traction.

[0034] During traction, because the weight 7 is located inside the tubular column 1, it is not easily touched or interfered with by passing personnel, thus avoiding the risk of the patient being injured by traction.

[0035] Example 2

[0036] like Figure 7 As shown, this embodiment is a preferred solution of Embodiment 1. A transparent angle ruler 8 is installed next to the fixed pulley 2 on the tubular column 1. The measuring plane of the angle ruler 8 is perpendicular to the axis of the fixed pulley 2. The center of the angle ruler 8 is located at the top of the outer ring of the fixed pulley 2. The angle ruler 8 can measure the angle of the traction rope 3 relative to the horizontal plane, that is, the traction angle, thereby improving the accuracy of the traction angle and enhancing the treatment effect.
