Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an abdominal drainage fixation device. Background Technology

[0002] In cases of ascites (such as malignant ascites, postoperative surgical drainage, and ascites due to cirrhosis), abdominal drainage is a crucial measure for preventing fluid accumulation, monitoring the internal environment, and controlling infection. Effective fixation and patency management of the drainage tube directly affect the quality of patient recovery and the success of the surgery. Traditional methods often rely on adhesive tape or sutures for fixation, which have drawbacks such as susceptibility to loosening due to sweat and exudate, skin damage, and difficulty adapting to changes in patient position. These methods frequently lead to risks such as accidental traction, local bending, and even unplanned tube removal.

[0003] Chinese patent document CN217960809U discloses an abdominal drainage and fixation device for gastrointestinal tumors, including a positioning component and an adjustment component. The positioning component includes a waist belt body, a tubing strap, and a fluid collection bag. The tubing strap is fixedly installed on the side of the waist belt body, and the fluid collection bag is detachably installed on the outside of the waist belt body. The two ends of the waist belt body are detachably connected. The adjustment component includes tubing columns, with several tubing columns fixedly installed on the side of the waist belt body and positioned between the fluid collection bag and the tubing strap. This design, through the waist belt body and the tubing strap, fixes the drainage tube to the outside of the waist belt body, making the drainage tube rely on the waist belt body for support. Since the waist belt body is directly worn on the patient, it is difficult to move, thus securing the drainage tube and preventing it from falling off, ensuring safety and reliability. The tubing columns allow for the winding and storage of longer drainage tubes, confining them within a certain range while ensuring unobstructed internal fluid flow.

[0004] The existing technology has the following problems: The purpose of drainage tube fixation devices is to prevent blockage caused by pulling or bending of the drainage tube. In clinical practice, blockage of abdominal drainage tubes is most commonly found in three key areas. Currently, most fixation devices mainly prevent mechanical blockage of the abdominal wall perforation segment by reducing bending through physical restraint. However, for blockage caused by the nature of the contents in the intracavitary segment, and for flow obstruction at the terminal connection due to improper maintenance, existing fixation devices lack both effective preventive mechanisms and auxiliary functions for unblocking. Summary of the Invention

[0005] The main objective of this invention is to provide an abdominal drainage fixation device that can effectively solve the problem of blockage in the side hole section of the drainage tube, the end interface of the drainage tube, or the connection point of the drainage bag, which is difficult to avoid or clear.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An abdominal drainage fixation device includes a fixation strap, a wire tie is fixedly connected to the upper side of the fixation strap, notches are provided at both ends of the fixation strap, a hollow fixation seat is provided on the right side of the fixation strap, and a filter mechanism is provided on the outer side of the hollow fixation seat.

[0007] Preferably, the fixing strap is bent into a loop so that the two notches are close to each other. The left side of the hollow fixing seat is fixedly connected to the right side of the loop fixing strap. The cable tie is located on the upper side of the loop fixing strap and at the end away from the hollow fixing seat. The structure formed by the two notches is circular. The lower side of the cable tie is detachably fixedly connected to the outer surface of the fixing strap. Both ends of the fixing strap are detachably fixedly connected. A heat dissipation plate is provided on the inner side wall of the fixing strap near the left side of the hollow fixing seat.

[0008] Preferably, the filtration mechanism includes a first disc-shaped mechanism cover and a second disc-shaped mechanism cover that are fixedly connected together and distributed on the left and right sides. A guide plate is rotatably connected to the inner left side of the first disc-shaped mechanism cover.

Several annularly distributed guide grooves are opened on the right side of the guide plate. An outlet pipe with an inner cavity is fixedly connected to the lower side of the first disc-shaped mechanism cover. A filter ring for filtering the liquid flowing to the outlet pipe is fixedly connected to the outer side of the guide plate.

[0009] Preferably, a motor is fixedly connected to the inner side of the hollow fixed base, and a non-circular insertion hole is opened in the middle of the right side of the guide plate. A transmission block inserted into the inner side of the insertion hole is fixedly connected to the output end of the motor. A collection box located inside the filter ring is embedded in the right side of the second disc-shaped mechanism cover near the upper side through a through hole. The collection box has two openings, one at the top and one at the bottom. A cover plate fixed by a buckle is fitted at the bottom opening on the right side of the collection box.

[0010] Preferably, a fixing sleeve is fixedly connected to the middle left side of the first disc-shaped mechanism cover and sleeved on the outside of the hollow fixing seat. A rubber sleeve that enhances the friction between the fixing sleeve and the hollow fixing seat is fixedly sleeved on the inner side of the fixing sleeve. The insertion hole extends to the left side of the first disc-shaped mechanism cover. A boss that sleeves on the inner side of the insertion hole on the first disc-shaped mechanism cover is fixedly connected to the right side of the hollow fixing seat.

[0011] Preferably, a plurality of annularly distributed partitions are fixedly connected to the inner side of the filter ring, and a limiting ring is fixedly connected to the inner right side of the second disc-shaped mechanism cover near the edge. The structure formed by the outer surface of the limiting ring and the outer surface of the guide plate is used to isolate the inner and outer sides of the cylindrical curved surface where the outer surface of the guide plate is located. Notches are provided on the upper and lower sides of the limiting ring.

[0012] Preferably, the outer side of the collection box is located inside the notch on the upper side of the limiting ring, and the top of the left wall of the collection box is provided with a protrusion for vibrating the partition passing over it, so that the partition can produce elastic deformation.

[0013] Preferably, the liquid inside the feed pipe flows from top to bottom, and the upper end of the feed pipe is tilted away from the side of the second disc-shaped mechanism cover.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Example 1, as Figure 1 , Figure 2 As shown, an abdominal drainage fixation device includes a fixation strap 1, a wire harness 2 fixedly connected to the upper side of the fixation strap 1, the wire harness 2 is used to fix the drainage tube to the lower side of the wire harness 2 to prevent the drainage tube from moving, the fixation strap 1 has notches 3 at both ends, a hollow fixing seat 4 is provided on the right side of the fixation strap 1, and a filter mechanism 5 is provided on the outer side of the hollow fixing seat 4. Except for the motor 515 and the transmission block 517, the other components on the filter mechanism 5 are disposable parts.

[0020] Preferably, the fixing strap 1 is bent into a loop so that the two notches 3 are close to each other. The fixing strap 1 is provided with a telescopic structure so that the size of the loop structure formed by the bending of the fixing strap 1 can be adjusted. This is prior art and will not be described in detail here. The left side of the hollow fixing seat 4 is fixedly connected to the right side of the loop fixing strap 1. The suture strap 2 is located on the upper side of the loop fixing strap 1 and at the end away from the hollow fixing seat 4. The structure formed by the two notches 3 is circular. The abdominal wall exit point of the drainage tube for peritoneal effusion drainage is located inside the notch 3. The lower side of the suture strap 2 is detachably fixed to the outer surface of the fixing strap 1. The left end of the suture strap 2 is directly fixed to the upper side of the fixing strap 1 by sewing. The other parts are fixed by Velcro. The two ends of the fixing strap 1 are detachably fixed. The two ends of the fixing strap 1 can be fixed together by snap fasteners. A heat dissipation plate is provided on the inner side wall of the fixing strap 1 near the left side of the hollow fixing seat 4.

[0021] It should be noted that during peritoneal effusion drainage, the fixation bandage 1 is placed under the patient's abdomen. After the peritoneal effusion is drained, the fixation bandage 1 is bent and the two ends are fixed with buckles so that the fixation bandage 1 is fitted on the patient's abdomen. The drainage tube is fixed with a suture bandage 2. The filtration mechanism 5 is used to filter the fluid drained from the drainage tube.

[0022] Example 2, as Figures 3-14 As shown, the filtration mechanism 5 includes a first disc-shaped mechanism cover 51 and a second disc-shaped mechanism cover 52 that are fixedly connected together and distributed on the left and right sides. A guide plate 57 is rotatably connected to the inner left side of the first disc-shaped mechanism cover 51. The second disc-shaped mechanism cover 52 is made of transparent material, while the guide plate 57 is made of opaque light-colored material or green material, which facilitates the observation of the liquid flowing inside the second disc-shaped mechanism cover 52 from the outside. At the same time, the light-colored material or green material can clearly observe the red blood.

[0023] The second disc-shaped mechanism cover 52 is fixedly connected to the lower right side of the middle part of the inlet pipe 53, which guides the liquid to the right side of the guide plate 57. The right side of the guide plate 57 has several annularly distributed guide grooves, which prevent the liquid from flowing forward and backward. The lower side of the first disc-shaped mechanism cover 51 is fixedly connected to the outlet pipe 54, which communicates with the inner cavity. The outer side of the guide plate 57 is fixedly connected to the filter ring 58, which filters the liquid flowing to the outlet pipe 54. The liquid is filtered by the filter ring 58 before entering the outlet pipe 54, which prevents blockage at the end interface of the guide pipe or the connection of the guide bag.

[0024] Preferably, a motor 515 is fixedly connected to the inner side of the hollow fixing base 4. The heat dissipation plate on the fixing strap 1 is used to dissipate heat from the motor 515. A non-circular insertion hole 516 is opened in the middle of the right side of the guide plate 57. A transmission block 517 inserted into the inner side of the insertion hole 516 is fixedly connected to the output end of the motor 515. The motor 515 drives the transmission block 517 to rotate, which in turn drives the guide plate 57 to rotate. When the guide plate 57 rotates, it drives the filter ring 58 to rotate, which in turn causes the filter ring 58 to carry the filter residue to the top of the guide plate 57. The right side of the second disc-shaped mechanism cover 52 is near the upper side and a collection box 55 is embedded in the filter ring 58 through a through hole. The collection box 55 is used to collect the filter residue. The collection box 55 has two openings, an upper and a lower opening. A cover plate 56 fixed by a buckle is fitted at the bottom opening on the right side of the collection box 55.

[0025] Preferably, a fixing sleeve 518 is fixedly connected to the middle left side of the first disc-shaped mechanism cover 51, which is sleeved on the outside of the hollow fixing seat 4. A rubber sleeve that enhances the friction between the fixing sleeve 518 and the hollow fixing seat 4 is fixedly sleeved on the inner side of the fixing sleeve 518. Several protruding rings are provided on the inner side of the rubber sleeve. The outer shape of the hollow fixing seat 4 matches the protruding rings to further improve the fixing ability of the fixing sleeve 518. The insertion hole 516 extends to the left side of the first disc-shaped mechanism cover 51. A boss that sleeves on the right side of the hollow fixing seat 4 is fixedly connected to the inner side of the insertion hole 516 on the first disc-shaped mechanism cover 51. The presence of the boss prevents relative rotation between the first disc-shaped mechanism cover 51 and the hollow fixing seat 4.

[0026] Preferably, a plurality of annularly distributed partitions 59 are fixedly connected to the inner side of the filter ring 58, and a limiting ring 510 is fixedly connected to the inner right side of the second disc-shaped mechanism cover 52 near the edge. The partitions 59 cooperate with the limiting ring 510 so that the filter residue on the filter ring 58 will not fall off due to gravity when it rotates from the bottom to the top. It can only fall into the inner side of the collection box 55 due to gravity when the filter residue is at the top.

[0027] The structure formed by the outer surface of the limiting ring 510 and the outer surface of the guide plate 57 is used to isolate the inner and outer sides of the cylindrical curved surface where the outer surface of the guide plate 57 is located. The upper and lower sides of the limiting ring 510 are provided with notches.

[0028] Preferably, the outer side of the collection box 55 is located inside the notch on the upper side of the limiting ring 510. The top of the left wall of the collection box 55 is provided with a protrusion for vibrating the partition 59 passing over it. The partition 59 can undergo elastic deformation. When the motor 515 drives the filter ring 58 to rotate and the partition 59 passes the protrusion, the movement of the partition 59 is interfered with due to the presence of the protrusion, which in turn causes the partition 59 to deform. After the partition 59 passes the protrusion, the partition 59 resets due to the material structure characteristics and vibrates, shaking off the filter residue on the surrounding filter ring 58.

[0029] Example 3, as Figure 15 As shown, the liquid inside the feed pipe 53 flows from top to bottom. The upper end of the feed pipe 53 is tilted away from the second disc-shaped mechanism cover 52. The tilted posture facilitates the connection between the drainage pipe and the upper end of the feed pipe 53. A piston rod 511 is sleeved on the inner side of the feed pipe 53. The piston rod 511 will not rotate relative to the feed pipe 53.

[0030] A guide ring 513 is fixedly connected to the right side of the flow deflector 57, and the center of the guide ring 513 is located below the inner center of the first disc-shaped mechanism cover 51. The distance from the right side of the flow deflector 57 to the inner right side of the second disc-shaped mechanism cover 52 is divided into three stages from the inside to the outside. The innermost position is attached to and rotatably connected to the inner right side of the second disc-shaped mechanism cover 52. The middle stage leaves a gap for the guide ring 513 to move, and the outermost stage leaves a gap for the collection box 55 to move.

[0031] The bottom of the left and right sides of the piston rod 511 is fitted with a connecting rod 512 through a square hole for engaging with the outside of the guide ring 513. When the connecting rod 512 moves to the right, it will automatically disengage from the guide ring 513. The left side of the connecting rod 512 has an arc-shaped groove corresponding to the guide ring 513, so that when the connecting rod 512 moves to the left, the guide ring 513 is engaged in the arc-shaped groove, and when the connecting rod 512 moves to the right, the guide ring 513 disengages from the arc-shaped groove.

[0032] It should be noted that when the motor 515 drives the guide plate 57 to rotate, the guide ring 513 rotates synchronously. When the guide ring 513 rotates, its position causes the guide ring 513 to drive the connecting rod 512 to move up and down, which in turn drives the piston rod 511 to move up and down in the feed pipe 53, thereby pumping the liquid in the drainage pipe. This allows for mechanical negative pressure suction when the side hole section of the drainage pipe is blocked.

[0033] Preferably, an elastic clamp 514 is fixedly connected to the right side of the feed pipe 53 corresponding to the position of the connecting rod 512. The elastic clamp 514 is used to clamp the magnet. The connecting rod 512 is made of magnetic material with magnetic poles distributed left and right. The piston rod 511, feed pipe 53, connecting rod 512, and elastic clamp 514 can be directly mounted on a plate. An installation hole is opened on the right side of the second disc-shaped mechanism cover 52, and the piston rod 511, feed pipe 53, connecting rod 512, and elastic clamp 514 are directly installed by fixing the plate into the installation hole. In this way, the first disc-shaped mechanism cover 51, the second disc-shaped mechanism cover 52, and the limiting ring 510 can be directly manufactured by injection molding, reducing costs.

[0034] It should be noted that the magnet attracts or repels the connecting rod 512. When negative pressure suction is required, the magnet repels the connecting rod 512, causing the connecting rod 512 to move away from the elastic clip 514 and be stuck on the outside of the guide ring 513. When negative pressure suction is not required, the magnet is flipped, causing the connecting rod 512 to move closer to the elastic clip 514, thereby causing the connecting rod 512 to detach from the guide ring 513.

[0035] The working principle of this invention is as follows: First, the motor 515 drives the transmission block 517 to rotate, which in turn drives the guide plate 57 to rotate. When the guide plate 57 rotates, it drives the filter ring 58 to rotate, causing the filter ring 58 to carry the filter residue to the top of the guide plate 57. The filter residue is then collected by the collection box 55. The liquid being drained is filtered by the filter ring 58. By using the motor 515 to drive the guide plate 57 to rotate, the filter ring 58 can filter and collect the filter residue simultaneously, effectively reducing the length of the drain pipe's end interface or the drain bag connection. In case of blockage, when the motor 515 drives the guide plate 57 to rotate, the guide ring 513 rotates synchronously. When the guide ring 513 rotates, its position causes the guide ring 513 to drive the connecting rod 512 to move up and down, which in turn drives the piston rod 511 to move up and down in the feed pipe 53, thereby pumping the liquid in the drain pipe. When the side hole section of the drain pipe is blocked, mechanical negative pressure suction can be performed. By driving the piston rod 511 to move, the motor 515 performs negative pressure suction on the inside of the feed pipe 53, thereby clearing the blockage when the side hole section of the drain pipe is blocked.
