Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a double-bag three-cavity fixing device. Background Art

[0002] Double-balloon triple-lumen tube compression hemostasis refers to the use of double-balloon triple-lumen tube to inflate and compress esophageal and gastric fundus varicose vein bleeding to achieve exact hemostasis. It is mainly used for emergency treatment of esophageal-gastric fundus varicose vein rupture bleeding caused by portal hypertension.

[0003] When using a double-balloon three-lumen tube to compress and stop bleeding of esophageal and gastric fundus varicose veins, a traction device is needed to ensure effective traction of the double-balloon three-lumen tube. At present, there is no standardized double-balloon three-lumen tube traction device in clinical practice. Medical staff generally use ropes, infusion stands, and weights to simply build a traction device, use ropes to connect the double-balloon three-lumen tube and the weight, and then hang the rope on the infusion stand to achieve traction of the double-balloon three-lumen tube. However, the compression hemostasis therapy of the double-balloon three-lumen tube generally takes a long time. This traction method is relatively fixed and inconvenient for patients to move. In the process of compression hemostasis treatment, the pressure in the airbag needs to be checked every 2 to 3 hours. If the pressure is insufficient, it should be promptly injected and pressurized. The esophageal balloon is deflated and traction is relaxed every 8 to 12 hours. In the above process, the double-balloon three-lumen tube and the traction device need to be disassembled, which is inconvenient. Therefore, a fixing device for the double-balloon three-lumen is proposed. Summary of the invention

[0044] like Figures 1 to 9 As shown, an embodiment of the present invention provides a double-capsule three-chamber fixation device, including a neck fixation mechanism 1, which is worn on the patient's neck to limit the movement of the patient's neck. A connecting frame assembly 2 is arranged on the surface of the neck fixation mechanism 1, and both ends of the connecting frame assembly 2 are detachably mounted on the surface of the neck fixation mechanism 1. A winding mechanism 3 is arranged on the upper surface of the connecting frame assembly 2, and the winding mechanism 3 is used to roll up the double-capsule three-chamber tube.

[0045] The winding mechanism 3 includes two groups of connecting blocks 36 arranged on the upper surface of the connecting frame assembly 2, and a connecting rod 31 is rotatably connected between the two groups of connecting blocks 36. A motor 34 is fixedly installed on the surface of one group of connecting blocks 36, and the output shaft of the motor 34 is fixedly connected to one end of the connecting rod 31. A plurality of clamping members are arranged on the surface of the connecting rod 31, and the clamping members are used to clamp the tube head of the double-bladder three-lumen tube. Annular baffles 32 are fixedly mounted on both sides of the outer surface of the connecting rod 31, and a plurality of support rods 33 are arranged on the outer surface of the connecting rod 31. The support rods 33 are parallel to the connecting rod 31 and are distributed in a circular array around the connecting rod 31. Both ends of the support rod 33 are connected to the annular baffle 32 by setting a retracting mechanism 5, and the retracting mechanism 5 enables the support rod 33 to move radially along the connecting rod 31.

[0046] In this embodiment, by setting up the neck fixing mechanism 1, during the process of the double-bag three-lumen tube compressing and stopping bleeding on the patient, the neck fixing mechanism 1 can prevent the patient's neck from moving, thereby ensuring that the double-bag three-lumen tube remains straight during traction and ensuring the strength of compression and hemostasis.

[0047] By setting the connecting frame assembly 2 to connect the winding mechanism 3 with the neck fixing mechanism 1, when using the double-capsule three-lumen tube for compression hemostasis, first, the double-capsule three-lumen tube is disinfected and air tightness tested before insertion, and the capsule of the double-capsule three-lumen tube is inserted into the patient's body and inflated, and then the three tube heads of the double-capsule three-lumen tube are clamped on the surface of the connecting rod 31 by a clamp, and then the connecting rod 31 and the support rod 33 are driven to rotate by the motor 34 to wind the double-capsule three-lumen tube, so that the double-capsule three-lumen tube can be tightened to achieve the traction effect on the double-capsule three-lumen tube. The winding mechanism 3, the connecting frame assembly 2 and the neck fixing mechanism 1 of the present invention are assembled into an integrated structure, so that the patient can perform some simple activities during the process of compression hemostasis treatment using the double-capsule three-lumen tube.

[0048] During the compression and hemostasis process of the double-bag three-lumen tube, in order to facilitate the inflation and deflation of the airbag, a retracting and expanding mechanism 5 is provided to cooperate with the support rod 33, so that the inflation and deflation operation can be performed without disassembling the double-bag three-lumen tube and the winding mechanism 3. Specifically, the retracting and expanding mechanism 5 can switch the position of the support rod 33 relative to the connecting rod 31, that is, the support rod 33 can be moved close to or away from the connecting rod 31. When the support rod 33 is close to the connecting rod 31, the support rod 33 is in a retracted state; when the support rod 33 is away from the connecting rod 31, the support rod 33 is in an expanded state. During the compression and hemostasis process of the double-bag three-lumen tube, the support rod 3 3 is in the open state, and the double-bag three-lumen tube is in the taut state, but the ventilation state of the double-bag three-lumen tube is not good at this time; when the double-bag three-lumen tube needs to be inflated or deflated, the retracting and stretching mechanism 5 can be used to switch the support rod 33 to the retracted state, and the double-bag three-lumen tube becomes relaxed. At this time, the ventilation state of the double-bag three-lumen tube is good, and the user can directly inflate or deflate the tube head of the double-bag three-lumen tube through a syringe. After the operation is completed, the retracting and stretching mechanism 5 is used to switch the support rod 33 to the open state, and the double-bag three-lumen tube is straightened again to achieve the purpose of traction; therefore, the inflation and deflation operation can be performed without disassembling the double-bag three-lumen tube and the winding mechanism 3.

[0049] It should be noted that when the double-bag three-lumen tube is rolled up by the winding mechanism 3, the staff can simply pull the double-bag three-lumen tube so that the double-bag three-lumen tube is neatly sheathed on the surface of the winding mechanism 3 in a single layer. In addition, when the double-bag three-lumen tube is rolled up, it is necessary to ensure that the tube head of the double-bag three-lumen tube leaks out to prevent the rolled double-bag three-lumen tube from covering the tube head, so as to facilitate the inflation and deflation of the double-bag three-lumen tube.

[0050] The retracting and unfolding mechanisms 5 include movable blocks 52 fixedly mounted at both ends of the support rod 33, a sliding groove 54 adapted to the movable block 52 is provided on the surface of the annular baffle 32, and the sliding groove 54 is arranged along the radial direction of the annular baffle 32, an annular plate 51 is movably sleeved on both ends of the connecting rod 31, a telescopic rod 53 is arranged between the movable block 52 and the annular plate 51, and both ends of the telescopic rod 53 are rotatably connected to the movable block 52 or the annular plate 51 through a rotating joint, the telescopic rod 53, the annular baffle 32 and the connecting rod 31 partially form a triangular structure, and a moving mechanism 6 is arranged on the surface of the connecting rod 31, and the moving mechanism 6 can drive the two groups of annular plates 51 to move along the surface of the connecting rod 31.

[0051] The moving mechanism 6 includes a cover body 61 fixedly installed on both sides of the outer surface of the connecting rod 31, an air cavity is formed between the inner surface of the cover body 61 and the outer surface of the connecting rod 31, a first piston plate 62 is installed inside the air cavity, a moving rod 63 is fixedly connected to the surface of the first piston plate 62, one end of the moving rod 63 passes through the cover body 61 and is connected to the annular plate 51, an air chamber 68 is opened in the middle part of the connecting rod 31, a moving push rod 66 is fixedly connected in the middle part of the air chamber 68, the moving push rod 66 is a double-headed structure, and the output end of the moving push rod 66 is fixedly connected to the second piston plate 67, ventilation pipes 65 are opened on both sides of the connecting rod 31, one end of the ventilation pipe 65 is communicated with the air chamber 68, and the other end of the ventilation pipe 65 is communicated with the air cavity, and a return spring 64 is sleeved on both sides of the connecting rod 31, the return spring 64 is located inside the cover body 61, one end of the return spring 64 is fixedly connected to the first piston plate 62, and the other end of the return spring 64 is fixedly connected to the inner surface of the cover body 61.

[0052] The first piston plate 62 is an annular structure. The inner surface of the first piston plate 62 is in sliding and sealing cooperation with the outer surface of the connecting rod 31 , and the outer surface of the first piston plate 62 is in sliding and sealing cooperation with the inner surface of the cover body 61 .

[0053] In this embodiment, the retracting and expanding mechanism 5 is used to drive the support rod 33 to move radially along the connecting rod 31 at the same time, thereby realizing the retracted and expanded state of the support rod 33. Specifically, when the support rod 33 needs to be switched from the retracted state to the expanded state, it is only necessary to drive the moving push rod 66 to extend, thereby driving the two sets of second piston plates 67 to move inside the air chamber 68, and the second piston plate 67 can push the gas in the air chamber 68, and the gas can enter the air cavity through the ventilation pipe 65, thereby pushing the first piston plate 62 inside the air cavity to move. At this time, the return spring 64 inside the cover body 61 is stretched, and the first piston plate 62 drives the moving rod 63 and the annular plate 51 to move, and the annular plate 51 moves toward the side close to the annular baffle 32, and the telescopic rod 53 between the annular plate 51 and the annular baffle 32 is deflected and stretched accordingly, thereby driving the movable block 52 to move inside the slide groove 54, thereby driving the support rod 33 to move toward the side away from the connecting rod 31, so that the support rod 33 is switched to the expanded state.

[0054] When the support rod 33 needs to be switched from the open state to the retracted state, it is only necessary to drive the movable push rod 66 to retract, thereby driving the second piston plate 67 to reset, thereby drawing the gas in the cover body 61 back to the inside of the air chamber 68, and the stretched reset spring 64 contracts, driving the first piston plate 62, the movable rod 63, the annular plate 51 and the telescopic rod 53 to move back, thereby driving the movable block 52 and the support rod 33 to move back, thereby switching the support rod 33 from the open state to the retracted state.

[0055] The clamping members are provided in three groups, each of which includes two groups of arc-shaped clamping plates 35, which are arranged opposite to each other, one end of the two groups of arc-shaped clamping plates 35 is fixedly connected to the connecting rod 31, and an opening is reserved between the ends of the two groups of arc-shaped clamping plates 35 away from the connecting rod 31.

[0056] In this embodiment, the size between the two groups of arc-shaped splints 35 is adapted to the size of the tube head of the double-bladder three-lumen tube. The arc-shaped splints 35 should be made of a material with a certain toughness. When clamping the tube head, the arc-shaped splints 35 can be opened first, and then the tube head can be placed inside the arc-shaped splints 35. After loosening the arc-shaped splints 35, the arc-shaped splints 35 can clamp the tube head.

[0057] The neck fixing mechanism 1 includes a neck guard plate 11 and a strap 12. Two groups of neck guard plates 11 are provided, and the outer surfaces of the two groups of neck guard plates 11 are fixedly connected with a connecting sleeve 13. Both ends of the strap 12 pass through the connecting sleeve 13 respectively, and the two ends of the strap 12 are connected by buttons or Velcro.

[0058] In this embodiment, the shape of the neck guard 11 is set according to the shape of the human neck. When fixing the patient's neck, two sets of neck guards 11 are placed on both sides of the patient's neck, and then the straps 12 are passed through the connecting sleeves 13 on the surface of the neck guards 11 and the neck guards 11 are tightened to fix the patient's neck.

[0059] The connecting frame assembly 2 includes sockets 21 fixedly mounted on the surfaces of the two groups of neck guard plates 11, each socket 21 has an insert plate 23 inserted therein, each insert plate 23 has an installation hole 25 at the bottom, each socket 21 has a fixing bolt 22 inserted thereon, one end of the fixing bolt 22 passes through the installation hole 25 and abuts against the inner surface of the socket 21, and a support seat 26 is provided at the upper end of the two groups of insert plates 23, and the support seat 26 can move up and down at the upper end of the insert plate 23.

[0060] Two sets of sliding rods are fixedly connected to both sides of the lower surface of the support seat 26, and a groove body adapted to the sliding rod is opened inside the plug plate 23, and the sliding rod is installed inside the groove body. A lifting push rod 24 is fixedly connected to the surface of the plug plate 23, and the telescopic end of the lifting push rod 24 is fixedly connected to the support seat 26.

[0061] In this embodiment, by setting up the connecting frame assembly 2, the winding mechanism 3 can be installed on the neck guard plate 11. Specifically, the two groups of plug plates 23 are respectively inserted into the sockets 21 on the surfaces of the two groups of neck guard plates 11, and then the fixing bolts 22 are passed through the mounting holes 25 on the plug plates 23 and the fixing bolts 22 are tightened, so that the plug plates 23 can be connected to the sockets 21. By driving the lifting push rod 24 to extend and retract, the height of the support seat 26 and the winding mechanism 3 can be adjusted, so that the traction angle of the double-bag three-lumen tube can be adjusted, which is convenient for use.

[0062] The support seat 26 is configured to be U-shaped, and both sides of the open end of the support seat 26 are connected to the connecting block 36 by configuring a measuring mechanism 4 .

[0063] The measuring mechanism 4 includes a movable groove 41 opened on both sides of the open end of the support seat 26, the connecting block 36 is adapted to the movable groove 41, and the connecting block 36 is slidably installed inside the movable groove 41, a pressure sensor 42 is arranged on one side of the movable groove 41, and a detection spring 43 is arranged inside the movable groove 41, one end of the detection spring 43 is fixedly connected to the connecting block 36, and the other end of the detection spring 43 is against the surface of the pressure sensor 42.

[0064] In this embodiment, by setting up a measuring mechanism 4, the traction force of the double-capsule three-chamber tube can be detected. Specifically, when in use, the detection spring 43 needs to be directed toward the patient's nasal cavity side. As the winding mechanism 3 winds the double-capsule three-chamber tube, the double-capsule three-chamber tube will pull the connecting block 36 to move along the moving groove 41, and the detection spring 43 inside the moving groove 41 will be compressed. The compressed detection spring 43 exerts pressure on the pressure sensor 42, and the pressure sensor 42 can detect the pressure size, that is, the traction force of the double-capsule three-chamber tube can be obtained.

[0065] It should be noted that both the lifting push rod 24 and the moving push rod 66 can be electric push rods, and corresponding battery components can be set inside the connecting rod 31 and on the surface of the support seat 26 to provide power for the lifting push rod 24 and the moving push rod 66. The circuits and related driver programs involved are all existing conventional technologies and will not be repeated here.

In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0067] The above is only a preferred embodiment of the present invention.
