Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a novel three-cavity two-balloon tube and a traction device. Background Art

[0002] Upper gastrointestinal bleeding and gastric bleeding are common clinical emergencies, and rapid and effective hemostasis is crucial for saving patients' lives. The three-chamber, two-balloon catheter, a classic treatment method, has been in clinical use for nearly 20 years and has become an important tool for controlling upper gastrointestinal bleeding, such as gastric bleeding and esophageal variceal bleeding. This device inflates the balloon to compress the bleeding site, achieving temporary hemostasis and buying valuable time for subsequent treatment. The specific structure of the three-chamber, two-balloon catheter is shown in Chinese Patent Publication No. CN112618921B, which describes a three-chamber, two-balloon catheter that dynamically monitors balloon pressure using a flexible sensing material. However, during clinical placement, it is difficult to quickly determine whether the bleeding is gastric or upper gastrointestinal bleeding, requiring repeated trial and error to achieve temporary hemostasis. Furthermore, the procedure requires high operator skill, and even experienced attending physicians struggle to ensure rapid and accurate placement every time in an emergency. Delayed placement often occurs, which not only affects the timeliness of hemostasis but also increases the risk of bleeding and other complications for patients.

[0003] At the same time, after the patient is intubated, it is usually required to keep the three-lumen two-balloon tube tilted at a certain angle (30°~50°) to the patient's body. This angle setting is intended to balance the pressure of the balloon on the bleeding site with the patient's comfort, reducing discomfort and potential complications caused by excessive pressure or uncomfortable angles. However, in most cases, the three-lumen two-balloon tube is retained for about 24 hours. If the bleeding is still not completely controlled, the retention time may be extended, sometimes to 48 hours or even longer. Long-term fixed posture traction not only increases the patient's physical burden, easily causes muscle fatigue and discomfort, but also may affect the patient's respiratory and circulatory function. More importantly, patients feel uncomfortable due to maintaining the same posture for a long time, and often need to adjust the traction device frequently, which not only increases the workload of nursing staff, but may also affect the compression effect of the balloon due to improper operation, and even lead to recurrence of bleeding. Summary of the Invention

[0004] One of the purposes of the present invention is to provide a new three-chamber two-balloon tube to solve the problem of inconvenient intubation and placement; the second purpose is to propose a traction device to solve the problem that the existing traction device cannot simultaneously change the traction angle according to the inclination angle of the patient's body.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A novel three-chamber two-balloon tube comprises a main tube, a first tube and a second tube;

[0007] The main pipe is a hollow structure with two ends open; the first pipe and the second pipe are respectively arranged in the main pipe;

[0008] A first water bag, a second water bag and a third water bag are fixedly arranged on the main pipe. The first water bag and the third water bag are respectively communicated with the first pipe, and the second water bag is communicated with the second pipe.

[0009] Furthermore, a first pipe head and a second pipe head are connected on the first pipe, the first pipe head passes through the main pipe and is connected to the first water bag, and the second pipe head passes through the main pipe and is connected to the second water bag;

[0010] The first tube head is located in the first water bag, and the second tube head is located in the second water bag;

[0011] Along the insertion direction of the main pipeline, the connection angle between the first pipe head and the second pipe head and the main pipeline is a;

[0012] Wherein, a is greater than 120 degrees.

[0013] According to the above technical solution, this design makes the connection angle between the first tube head and the second tube head and the main tube more gentle, reducing the resistance during intubation and avoiding damage to the nasal cavity or digestive tract mucosa during insertion, thereby improving the smoothness of intubation and patient comfort. In specific operations, medical staff insert the main tube into the patient's body through the nasal cavity. Since the first tube head and the second tube head are connected to the main tube at a larger angle, they can pass through the nasal cavity and the curved parts of the digestive tract more smoothly, reducing friction and irritation to the tissues. When the catheter reaches the target position, liquid is injected into the first water bag and the second water bag through the first pipe to inflate them and compress the bleeding areas of the gastric antrum and gastric fundus respectively, achieving precise hemostasis. This design not only improves the success rate of intubation, but also reduces operational risks, providing patients with a safer and more comfortable treatment experience.

[0014] On the other hand, the present invention also provides a traction device, including a reclining frame, an adjustment frame, a driving unit and a traction member;

[0015] The adjustment frame and the driving unit are installed on the reclining frame;

[0016] The traction member is arranged on the adjustment frame;

[0017] The reclining frame comprises a lying unit and a backrest unit, wherein the backrest unit is hinged to the lying unit;

[0018] The driving unit is connected to the adjustment frame and the backrest unit, and is used to drive the adjustment frame to rise or fall; at the same time, it drives the backrest unit to rotate clockwise or counterclockwise;

[0019] It also includes the novel three-chamber two-balloon tube as described above, and the novel three-chamber two-balloon tube is connected to the traction member.

[0020] According to the above technical solution, the traction device of the present invention cleverly combines a reclining frame, an adjustment frame, a drive unit, a traction member, and a novel three-chamber two-balloon tube, providing patients with an efficient and comfortable hemostasis treatment solution. The reclining frame in the device is composed of a lying unit and a backrest unit. The backrest unit can be hinged to the lying unit to facilitate the patient's adjustment from a lying position to a sitting position, or from a sitting position to a lying position. The novel three-chamber two-balloon tube is connected to the adjustment frame via a traction member to ensure that it always maintains the correct position during the hemostasis treatment process. The drive unit can not only drive the adjustment frame to rise and fall, but also simultaneously drive the backrest unit to rotate clockwise or counterclockwise. When the patient needs to adjust the body angle, the drive unit will accordingly drive the adjustment frame and the backrest unit to move in coordination. In particular, when the backrest unit flips upward, that is, the patient's body gradually becomes sitting, the drive unit will automatically drive the adjustment frame down, so that the traction part and the three-chamber two-balloon tube are adjusted accordingly to ensure that their angle with the patient's body always remains within the range of 30-50 degrees. This design aims to optimize the compression effect of the airbag on the bleeding area, while reducing the patient's discomfort and avoiding potential complications caused by excessive compression or uncomfortable angles.

[0021] Furthermore, the lying unit includes a bottom plate, a lying plate and two guardrails, the lying plate is fixedly arranged on the upper surface of the bottom plate, and the two guardrails are detachably mounted on both sides of the bottom plate;

[0022] The backrest unit includes an inclined plate and a connecting column. The connecting column is fixedly arranged at the bottom of the inclined plate. The inclined plate is hinged to the lying plate.

[0023] According to the above technical solution, the reclining unit includes a base, a reclining board, and two guardrails. The reclining board is securely fixed to the upper surface of the base, providing a support surface for the patient to lie flat. The two guardrails are detachably mounted on either side of the base to ensure the patient's safety during posture adjustment or treatment. The backrest unit consists of a tilting plate and a connecting column. The connecting column is securely mounted on the bottom of the tilting plate to support the tilting plate, which can rotate around its hinge point with the reclining plate. When the patient needs to adjust their posture, the drive unit will activate, pushing the backrest unit to rotate clockwise or counterclockwise around the hinge point, thereby changing the patient's body angle, achieving the patient's movement purpose, and avoiding muscle fatigue and discomfort.

[0024] Furthermore, a mounting seat is fixedly provided below the base plate, a support member is hinged on the mounting seat, the support member can be extended or shortened, and an end of the support member is hinged to the connecting column.

[0025] Furthermore, the support member includes a column barrel and a column rod, one end of the column rod is threadedly connected to a second screw rod, the column rod and the second screw rod are arranged in the column barrel, and the end of the second screw rod extends into the column rod and is threadedly connected to the column rod. When the second screw rod rotates, it can drive the column rod to move in the column barrel.

[0026] According to the above technical solution, in the traction device of the present invention, a mounting seat is fixed below the base plate, and an extendable or shortened support member is cleverly hinged on the mounting seat, which provides stable support for the backrest unit and allows it to adjust its angle. The support member is composed of a column and a column rod, one end of the column rod is connected to a second screw rod by a thread, and the column rod and the second screw rod are placed together inside the column tube. This design allows the column rod to extend or shorten inside the column tube when the second screw rod rotates. When the angle of the backrest unit needs to be adjusted, the user can change the length of the support member by rotating the second screw rod, thereby driving the tilting plate to rotate around its hinge point with the flat plate.

[0027] Furthermore, the adjustment frame includes a mounting bar, a fixed pulley and two guide telescopic rods, the bottoms of the two guide telescopic rods are fixedly arranged on the bottom plate, and the tops of the two guide telescopic rods are connected to the mounting bar;

[0028] The fixed pulley is rotatably arranged on the mounting bar.

[0029] According to the above technical solution, the fixed pulley is flexibly rotatably mounted on the mounting bar, providing a smooth moving path for the traction rope.

[0030] The traction device consists of a traction rope and a counterweight. The traction rope cleverly passes around the fixed pulley, with one end connected to the counterweight and the other end tightly connected to the three-chamber two-balloon tube. When the water balloon of the three-chamber two-balloon tube is filled with water, the gravity of the counterweight causes the traction rope to gently pull back the three-chamber two-balloon tube, ensuring that the first water balloon, the second water balloon and the third water balloon can fit tightly and effectively compress the upper gastrointestinal bleeding or gastric varices. This design not only has a compact structure and improves the accuracy and efficiency of hemostasis, but also achieves stable traction of the three-chamber two-balloon tube through the natural drooping of the counterweight and the guiding effect of the fixed pulley, providing patients with a safer and more reliable treatment plan.

[0031] Furthermore, the driving unit includes a driving housing, a worm wheel, a worm and a second screw, wherein the worm wheel and the worm are rotatably arranged in the driving housing, and the worm wheel is meshed with the worm;

[0032] The drive housing is provided with a handle for rotation on the outside, and the handle extends into the drive housing and is coaxially connected to the worm;

[0033] One end of the worm away from the handle is connected to a flexible shaft, and the flexible shaft is connected to the second screw;

[0034] An internal threaded hole is provided at the center of the worm wheel, and the second screw is installed in the internal threaded hole. When the worm rotates, the second screw can be driven to rise or fall.

[0035] The top of the second screw is connected to the mounting bar.

[0036] The drive unit of the present invention, based on the above technical solution, is ingeniously designed, integrating key components such as the drive housing, worm gear, worm, and second screw. The worm gear and worm are tightly meshed within the drive housing, forming a stable transmission structure. By turning a handle, the caregiver rotates a flexible shaft coaxially connected to the worm, the other end of which is connected to the second screw, achieving power transmission.

[0037] As the worm rotates, the worm wheel meshing with it drives the second screw in the internal threaded hole at its center to move up or down. The top of the second screw is connected to the mounting bar of the adjustment frame. Therefore, the lifting and lowering movement of the second screw directly drives the entire adjustment frame and the fixed pulley and traction member thereon to move synchronously; at the same time, the rotation of the worm is coaxially connected to the second screw through the flexible shaft, which also indirectly adjusts the angular length of the support member, thereby changing the angle of the backrest unit, thereby achieving adjustment of the patient's body angle within a suitable traction angle range.

[0038] Furthermore, the traction member includes a traction rope and a counterweight block, the traction rope is placed on the fixed pulley, one end of the traction rope is connected to the configuration block, and the other end of the traction rope is connected to the three-chamber two-balloon tube.

[0039] Furthermore, a plurality of movable wheels are provided at the bottom of the reclining frame.

[0040] According to the above technical solution, the movable wheels enable the entire traction device to be easily transferred to different locations, thereby improving the flexibility and convenience of use, and can significantly improve work efficiency, especially when rapid response or transfer of treatment scenarios is required.

[0041] Beneficial effects of the present invention:

[0042] 1. The present invention injects liquid into the first water bag and the third water bag through the first pipe, so that the two are inflated and compress specific parts of the esophagus and the fundus of the stomach respectively. At the same time, liquid is injected into the second water bag through the second pipe, so that it is inflated and compresses other possible bleeding points in the stomach, thereby achieving multi-point precise compression hemostasis. Compared with the traditional three-chamber two-balloon tube, this new design has significant advantages: first, the traditional three-chamber two-balloon tube has only two air balloons, which are used to compress the lower esophagus and the gastric fundus respectively, while the new three-chamber two-balloon tube covers more bleeding points by adding a third water balloon, which is especially suitable for complex or multiple bleeding situations; second, the traditional air balloon is inflated with gas, which may have the risk of inaccurate pressure control or gas leakage, while the new three-chamber two-balloon tube is inflated with liquid, and the pressure is more stable and easier to control, reducing the risk of tissue damage; in addition, by controlling the three water balloons separately through independent first and second tubes, a more flexible compression strategy can be achieved, such as selectively inflating specific water balloons according to the different bleeding sites, thereby improving hemostasis efficiency and reducing compression on non-bleeding areas, providing a more efficient and reliable solution for the treatment of esophageal and gastric variceal bleeding.

[0043] 2. The traction device of the present invention cleverly combines a reclining frame, an adjustment frame, a drive unit, a traction member, and a novel three-chamber two-balloon tube, providing patients with an efficient and comfortable hemostasis treatment solution. The reclining frame in the device consists of a lying unit and a backrest unit. The backrest unit can be hinged to the lying unit to facilitate the patient's adjustment from a lying position to a sitting position, or from a sitting position to a lying position. The novel three-chamber two-balloon tube is connected to the adjustment frame via a traction member to ensure that it always maintains the correct position during the hemostasis treatment process. The drive unit can not only drive the adjustment frame to rise and fall, but also simultaneously drive the backrest unit to rotate clockwise or counterclockwise. When the patient needs to adjust the body angle, the drive unit will drive the adjustment frame and the backrest unit to move in coordination accordingly. In particular, when the backrest unit flips upward, that is, the patient's body gradually becomes sitting, the drive unit will automatically drive the adjustment frame down, so that the traction part and the three-chamber two-balloon tube are adjusted accordingly to ensure that their angle with the patient's body always remains within the range of 30-50 degrees. This design aims to optimize the compression effect of the airbag on the bleeding area, while reducing the patient's discomfort and avoiding potential complications caused by excessive compression or uncomfortable angles.

DETAILED DESCRIPTION

[0055] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0056] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0057] It should be noted that conventional three-chamber, two-balloon catheters consist of three chambers and two balloons, one for gastric and esophageal balloon inflation and gastric suction, respectively. The two balloons, through inflation, compress the bleeding site to achieve hemostasis. Before using a three-chamber, two-balloon catheter, medical staff must conduct thorough preparations, including confirming patient 6's identity, assessing the indication, checking vital signs, and explaining the procedure in detail to obtain their consent. They must also prepare the catheter, lubricant, syringe, aspirator, and other related equipment. To begin the procedure, the patient 6 assumes a semi-recumbent position with their head tilted to one side. After thoroughly lubricating the catheter, the medical staff slowly inserts the catheter through the nasal cavity or mouth, ensuring that it enters the stomach. The insertion depth is typically 50-60 cm. Then, first inject 250-300 ml of air into the gastric balloon to inflate the balloon and gently pull back the tube to ensure that the gastric balloon compresses the varices at the fundus of the stomach. Then perform intragastric suction to extract the gastric fluid. If the extracted gastric fluid contains blood, the bleeding may not have stopped yet, which means it is upper gastrointestinal bleeding. In this case, inject 100-150 ml of air into the esophageal balloon to inflate the esophageal balloon to compress the varices at the lower end of the esophagus, thereby achieving the effect of compression to stop bleeding.

[0058] This embodiment proposes a new type of three-chamber two-balloon tube. The three-chamber two-balloon tube is divided into two different lengths according to different usage conditions. The first three-chamber two-balloon tube is inserted into the patient's body from the patient's mouth, and the distance from the incisors to the jejunum is about 75 cm; the second three-chamber two-balloon tube is inserted into the patient's body from the nasal cavity, and the nasointestinal tube is about 80 cm from the nose to the jejunum. Figure 1 and Figure 2As shown, the apparatus comprises a main conduit 101, a first conduit 102, and a second conduit 103. The main conduit 101 is a hollow structure with openings at both ends, and can be used for suctioning gastric accumulation and providing enteral nutrition. The first conduit 102 and the second conduit 103 are respectively disposed within the main conduit 101. A first water bag 104, a second water bag 105, and a third water bag 106 are fixedly disposed on the main conduit 101. The first water bag 104 and the third water bag 106 are respectively connected to the first conduit 102, and the second water bag 105 is connected to the second conduit 103. In this embodiment, a scale is provided on the first conduit 101, with the distance between adjacent scale marks being 5 cm. The distance between the second water bag 105 and the third water bag 106 is 15 cm to 20 cm. The distance between the end of the main conduit 101 and the first water bag 104 is 3 to 5 cm.

[0059] According to the above technical solution, its working principle is to first pass the three-chamber two-balloon tube through the first water balloon 104 through the pylorus and into the jejunum under ultrasound guidance. The second water balloon 105 is in the stomach position, the first water balloon 104 is in the duodenum or jejunum at this time, and the third water balloon 106 is in the lower esophagus. When in use, the second water balloon 105 is filled with 200ml of water for water compression. If it is found that bright red liquid can be continuously drained out, it means that it is not just gastric bleeding. By filling the first water balloon 104 and the third water balloon 106 with water for compression and hemostasis, they are inflated and compress other possible bleeding points in the stomach, thereby achieving multi-point precise compression and hemostasis.

[0060] Compared with the traditional three-chamber two-balloon tube, the traditional three-chamber two-balloon tube has only two air balloons, which are used to compress the lower end of the esophagus and the fundus of the stomach respectively. The new three-chamber two-balloon tube covers more bleeding points by adding a third water balloon 106, which is particularly suitable for complex or multiple bleeding situations; secondly, the traditional air balloon is inflated with gas, which may have the risk of inaccurate pressure control or gas leakage, while the new three-chamber two-balloon tube is inflated with liquid, and the pressure is more stable and easy to control, reducing the risk of tissue damage; in addition, by controlling the three water balloons respectively through the independent first tube 102 and the second tube 103, a more flexible compression strategy can be achieved, such as selectively inflating specific water balloons according to the different bleeding sites, thereby improving the hemostasis efficiency and reducing the compression on the non-bleeding area, providing a more efficient and reliable solution for the treatment of esophageal variceal bleeding.

[0061] Specific operation: The catheter head of the main conduit 101 is placed into the stomach under ultrasound guidance. First, the first water balloon 104 is filled with water to locate the position of the catheter head. Then, the catheter head of the main conduit 101 is pushed to the pyloric part and the position of the gastric antrum is confirmed. After the water in the first water balloon 104 is drained, the catheter head of the main conduit 101 is continued to be pushed to the horizontal part of the duodenum. The first water balloon 104 is inflated again to confirm the position. At the same time, the second water balloon 105 is filled with water and positioned at the bottom of the stomach to compress the bleeding part of the gastric fundus and achieve hemostasis function. At the same time, through the synergistic effect of multiple water balloons, it can effectively stop bleeding and achieve jejunal feeding, meet complex clinical needs, reduce the difficulty of operation, and facilitate intubation.

[0062] As a preferred embodiment, Figure 1 and Figure 2 As shown, the first pipe 102 is connected with a first tube head 1021 and a second tube head 1022. The first tube head 1021 passes through the main pipe 101 and is connected to the first water bag 104, and the second tube head 1022 passes through the main pipe 101 and is connected to the second water bag 105; the first tube head 1021 is located in the first water bag 104, and the second tube head 1022 is located in the second water bag 105; along the insertion direction of the main pipe 101, the connection angle between the first tube head 1021 and the second tube head 1022 and the main pipe 101 is a; wherein, a is greater than 120 degrees.

[0063] According to the above technical solution, this design makes the connection angle between the first tube head 1021 and the second tube head 1022 and the main tube 101 more gentle, reducing the resistance during the intubation process, and at the same time avoiding damage to the nasal cavity or digestive tract mucosa of the patient 6 during insertion, thereby improving the smoothness of intubation and the comfort of the patient 6. In the specific operation, the medical staff inserts the main tube 101 into the patient 6 through the nasal cavity. Since the connection angle between the first tube head 1021 and the second tube head 1022 and the main tube 101 is larger, it can pass through the nasal cavity and the curved parts of the digestive tract more smoothly, reducing friction and irritation to the tissue; when the main tube 101 reaches the target position, liquid is injected into the first water bag 104 and the second water bag 105 through the first tube 102, causing them to inflate and compress the bleeding areas of the gastric antrum and gastric fundus respectively, achieving precise hemostasis, and providing a safer and more comfortable treatment experience for the patient 6.

[0064] On the other hand, the present invention also provides a traction device, such as Figures 3 to 9 As shown, it includes a reclining frame 2, an adjusting frame 3, a driving unit 4 and a traction member 5; the adjusting frame 3 and the driving unit 4 are installed on the reclining frame 2;

[0065] The traction member 5 is provided on the adjustment frame 3; the reclining frame 2 includes a reclining unit 21 and a backrest unit 22, and the backrest unit 22 is hinged to the reclining unit 21; the driving unit 4 is connected to the adjustment frame 3 and the backrest unit 22 respectively, and the driving unit 4 is used to drive the adjustment frame 3 to rise or fall; at the same time, it also drives the backrest unit 22 to rotate clockwise or counterclockwise;

[0066] It also includes the novel three-chamber two-balloon tube as mentioned above, which is connected to the traction member 5.

[0067] According to the above technical solution, the traction device of the present invention cleverly combines a reclining frame 2, an adjustment frame 3, a drive unit 4, a traction member 5, and a novel three-chamber, two-balloon catheter, providing a highly effective and comfortable hemostatic treatment solution for patient 6. The reclining frame 2 in the device comprises a reclining unit 21 and a backrest unit 22. The backrest unit 22 is hingedly connected to the reclining unit 21, facilitating adjustment of the patient 6 from a reclining position to a sitting position, or vice versa. The three-chamber, two-balloon catheter of the present application is connected to the adjustment frame 3 via the traction member 5, ensuring that the correct position is maintained during the hemostatic treatment process to compress and stop bleeding at the relevant parts. The drive unit 4 not only drives the adjustment frame 3 up and down but also simultaneously drives the backrest unit 22 to rotate clockwise or counterclockwise. When the patient 6 needs to adjust the angle of their body, the drive unit 4 drives the adjustment frame 3 and backrest unit 22 to move in coordination. In particular, when the backrest unit 22 flips upward, the patient 6 gradually transitions from a reclining position to a sitting position, thereby reducing muscle fatigue and discomfort. The driving unit 4 will automatically drive the adjustment frame 3 to descend, so that the positions of the traction member 5 and the three-chamber two-balloon tube are adjusted accordingly, ensuring that the angle between the three-chamber two-balloon tube and the patient's 6 body is always maintained within the range of 30-50 degrees. This design aims to optimize the compression effect of the first water bag 104, the second water bag 105 and the third water bag 106 on the bleeding site, while reducing the discomfort of the patient 6 and avoiding potential complications caused by excessive compression or uncomfortable angles.

[0068] It should be noted that, and in accordance with the essential spirit of the present invention, a person skilled in the art can, through a limited number of experiments, design a linear relationship between the height change of the tilting plate 221 rotating around its hinge point with the lying plate 212 and the rise and fall of the adjustment frame 3, so that the angle between the three-chamber two-balloon tube and the patient's 6 body is always in the optimal range of 30-50 degrees.

[0069] As a preferred embodiment, Figure 3 、 Figure 4 and Figure 5As shown, the reclining unit 21 includes a base plate 211, a reclining plate 212, and two guardrails 213. The reclining plate 212 is fixed to the upper surface of the base plate 211 and firmly fixed to the upper surface of the base plate 211, providing a support surface for patient 6 to lie flat. The two guardrails 213 are mounted on both sides of the base plate 211 in a snap-fit ​​manner and are removable to ensure the safety of patient 6 during posture adjustment or treatment. The backrest unit 22 includes a tilting plate 221 and a connecting post 222. The connecting post 222 is fixed to the bottom of the tilting plate 221. The tilting plate 221 is hinged to the reclining plate 212 and can rotate about its hinge point with the reclining plate 212. When patient 6 needs to adjust his posture, the drive unit 4 is activated to push the backrest unit 22 to rotate clockwise or counterclockwise about the hinge point, thereby changing the body angle of patient 6, achieving the purpose of patient 6's movement and avoiding muscle fatigue and discomfort.

[0070] As a preferred embodiment, Figure 7 As shown, a mounting base 23 is fixedly provided below the bottom plate 211, and a support member 24 is hinged on the mounting base 23. The support member 24 can be extended or shortened, as shown in FIG. Figure 6 As shown, the right end of the support member 24 is hinged to the connecting column 222 .

[0072] According to the above technical solution, in the traction device of the present invention, a mounting seat 23 is fixed below the base plate 211, and an extendable or shortened support member 24 is cleverly hinged on the mounting seat 23. The support member 24 provides stable support for the backrest unit 22 and allows it to be adjusted in angle. The support member 24 is composed of a column 241 and a column rod 242. The left end of the column rod 242 is connected to the second screw rod 44 by a thread. The column rod 242 and the second screw rod 44 are placed together inside the column barrel 241. This design allows the column rod 242 to extend or shorten inside the column barrel 241 when the second screw rod 44 rotates. When the angle of the backrest unit 22 needs to be adjusted, the caregiver can change the length of the support member 24 by indirectly rotating the second screw rod 44, thereby driving the tilting plate 221 to rotate around its hinge point with the flat plate 212.

[0073] As a preferred embodiment, Figure 3 and Figure 4As shown, the adjustment frame 3 includes a mounting bar 31, a fixed pulley 32, and two telescopic guide rods 33. The bottoms of the two telescopic guide rods 33 are fixedly mounted on the base plate 211 and can be extended or shortened. The tops of the two telescopic guide rods 33 are connected to the mounting bar 31. The fixed pulley 32 is rotatably mounted on the mounting bar 31, providing a smooth travel path for the traction rope 51.

[0074] The traction member 5 comprises a traction rope 51 and a counterweight 52. The traction rope 51 is mounted on the fixed pulley 32, with one end connected to the counterweight and the other end connected to the three-chamber, two-balloon tube. The traction member 5, consisting of the traction rope 51 and the counterweight, 52, cleverly passes over the fixed pulley 32, with one end connected to the counterweight and the other end tightly connected to the three-chamber, two-balloon tube. When the water bladder of the three-chamber, two-balloon tube is filled with water, the gravity of the counterweight 52 causes the traction rope 51 to gently pull the tube back, allowing the first, second, and third water bladders 104, 105, and 106 to effectively compress the area of ​​upper gastrointestinal bleeding or gastric varices, achieving hemostasis and providing a safer and more reliable treatment solution for patient 6.

[0075] As a preferred embodiment, Figure 1 、 Figure 8 and Figure 9 As shown, the drive unit 4 includes a drive housing 41, a worm gear 42, a worm 43 and a second screw 44. The worm gear 42 and the worm 43 are rotatably arranged in the drive housing 41. The drive housing 41 is fixed to the base plate 211, and the worm gear 42 is engaged with the worm 43. A handle 45 is rotatably provided on the outside of the drive housing 41. The handle 45 extends into the drive housing 41 and is coaxially connected to the worm 43. The end of the worm 43 away from the handle 45 (i.e. Figure 8 The right end of the middle worm 43 is connected to a flexible shaft 46, which is connected to the second screw 44. The purpose of the flexible shaft 46 is to avoid interference when the device is connected. The flexible shaft 46 can make the worm 43 and the second screw 44 non-coaxially connected when connected.

[0076] An internal threaded hole is provided at the center of the worm wheel 42, and a second screw 44 is installed in the internal threaded hole. When the worm 43 rotates, it can drive the second screw 44 to rise or fall; the top of the second screw 44 is connected to the mounting bar 31. According to the above technical solution, the drive unit 4 of the present invention is exquisitely designed. It integrates key components such as the drive housing 41, the worm wheel 42, the worm 43 and the second screw 44. The worm wheel 42 and the worm 43 are tightly meshed inside the drive housing 41 to form a stable transmission structure. By turning the handle 45, the accompanying person can drive the flexible shaft 46 coaxially connected to the worm 43 to rotate, and the other end of the flexible shaft 46 is connected to the second screw 44 to realize power transmission. As the worm 43 rotates, the worm wheel 42 meshing with it will drive the second screw 44 in the internal threaded hole at its center position to move up or down. The top of the second screw 44 is connected to the mounting bar 31 of the adjustment frame 3. Therefore, the lifting and lowering movement of the second screw 44 will directly drive the entire adjustment frame 3 and the fixed pulley 32 and the traction member 5 thereon to move synchronously; at the same time, the rotation of the worm 43 is coaxially connected to the second screw 44 through the flexible shaft 46, which also indirectly adjusts the angular length of the support member 24, and then changes the angle of the backrest unit 22, thereby realizing the adjustment of the patient's 6 body angle within the appropriate traction angle range.

[0077] As a preferred embodiment, Figure 2 、 Figure 3 and Figure 4 As shown, a plurality of movable wheels are provided at the bottom of the reclining frame 2. In the present application, there are four movable wheels, which allow the entire traction device to be easily moved to different locations, improving the flexibility and convenience of use, especially when rapid response or transfer of treatment scenarios is required, which can improve treatment efficiency.

[0078] After the medical staff completes the intubation of the patient 6 and fills the first water bag 104, the second water bag 105 and the third water bag 106 with water, the three-chamber two-balloon tube is connected to the traction rope 51. Under the action of the gravity of the counterweight 52, the traction rope 51 gently pulls back the three-chamber two-balloon tube to ensure that the first water bag 104, the second water bag 105 and the third water bag 106 are tightly fitted and effectively compress the upper gastrointestinal bleeding or gastric varices to achieve precise hemostasis. When the patient 6 lies flat for a period of time, he or she is prone to muscle fatigue and needs to change posture to move the body. The caregiver can adjust the handle 45 of the drive unit 4 to drive the worm 43 to rotate clockwise, driving the second screw 44 to rotate clockwise. At this time, the support member 24 extends and pushes the connecting column 222 to make the tilting plate 221 rotate around its hinge point with the lying plate 212, changing from a lying state to a sitting state; at the same time, the worm 43 drives the worm wheel 42 to rotate counterclockwise. At this time, the second screw 44 descends, causing the adjustment frame 3 and the fixed pulley 32 and the traction member 5 thereon to move synchronously to maintain the angle between the three-chamber two-balloon tube and the patient 6 body always within the optimal range of 30-50 degrees.

[0079] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by those skilled in the art based on the present invention is within the protection scope of the present invention.
