Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adjustable fixation device for a drainage tube. Background Technology

[0002] Patent CN221357888U discloses a medical drainage tube and a fixing structure for the drainage tube. The tube includes a drainage tube with an anti-displacement component movably sleeved on its outer wall and a fixing component movably sleeved on its outer wall. When using this device, the anti-displacement component and an adhesive patch can be used to attach the device to the local skin, thereby fixing the first mounting bracket to the skin. Then, the drainage tube is placed on the upper inner surface of a rubber pad. Finally, through the cooperation of the first fixing rod, the connecting rod, and the second fixing rod, the second mounting bracket can be flipped over.

[0003] Existing drainage tube fixing devices typically only fix and restrict the drainage tube within the working area, and do not play an auxiliary role when connecting the drainage tube to the three-way valve, thus reducing the convenience of connecting the drainage tube to the three-way valve.

[0004] Therefore, an adjustable fixing device for the drainage tube is proposed to solve the problems mentioned above. Summary of the Invention

[0006] Preferably, the adjustment frame has a channel, and the inner sidewall of the channel has an inflatable bladder.

[0007] Preferably, an outer cylinder is fixedly connected inside the adjusting frame, an inner cylinder is slidably connected inside the outer cylinder, the side wall of the inner cylinder is fixedly connected to the first driving member, and the first driving member drives the second driving member to move through the transmission member.

[0008] Preferably, the first driving member and the second driving member are respectively engaged with the two ends of the transmission member; The second driving component is fixedly connected to the side wall of the embedded plate.

[0009] Preferably, spray rings are provided at both ends of the embedded plate inside the adjustment frame.

[0010] Preferably, a winding drum is rotatably connected to the adjustment frame via a torsion spring, and a traction rope is wound on the winding drum. The other end of the traction rope is fixedly connected to the embedded plate.

[0011] Preferably, an auxiliary frame is fixedly connected to the side wall of the adjusting frame, and a liquid accumulation tank and a conveying tank are respectively provided at the upper and lower ends of the auxiliary frame; A conveyor plate is slidably connected inside the conveyor trough, and one end of the conveyor plate is slidably inserted into the limiting frame.

[0012] Preferably, a second spring is fixedly connected inside the limiting frame. One end of the second spring is fixedly connected to the side wall of the conveyor plate, the side wall of the conveyor plate is fixedly connected to the power component, and the other end of the power component slides through the side wall of the auxiliary frame and is fixedly connected to the embedded rod. The power component is a pull rope.

[0013] Preferably, the first driving component and the second driving component are racks and pinions, and the transmission component is a gear; The winding drum is fixedly connected to the lower end of the absorption plate.

[0014] Preferably, the other end of the telescopic rod is connected to a mating assembly; The top of the base is fixedly connected with a Velcro assembly, and the bottom of the base is fixedly connected with a hook. The assembly consists of the base, the Velcro assembly, and the hook.

[0015] Compared with the prior art, the present invention provides an adjustable fixing device for drainage tubes, which has the following advantages: The three detachable parts of this invention—the deformable frame, the adjusting frame, and the base—can be used in combination or individually, enhancing flexibility and convenience. The deformable frame can be bent into any shape, guiding the drainage tube to a specific path according to the bed space and the patient's position. The deformable frame can effectively prevent external objects from directly pressing on the surface of the drainage tube.

[0016] This invention utilizes a push-pull insert rod to drive a pull rope, transmission components, traction rope, and power components. Simultaneously, it unfolds a shielding plate, exposes the operating port, inflates an airbag, automatically clamps the connecting hose, and rotates the absorption plate to its end to absorb residual liquid and pre-draw disinfectant into the delivery tank, preparing for subsequent spraying.

[0017] 3. When the drainage tube is replaced, the inflation bladder expands and squeezes the surface of the connecting hose to close it, effectively preventing residual liquid inside the tube from dripping; the absorption plate moves to the end of the channel in conjunction with the embedded plate, accurately absorbing the small amount of liquid flowing out after the connecting hose is clamped, keeping the operating area clean; when the connector is inserted into the connecting hose, the squeezing contact improves the tightness of the connection and prevents it from falling off.

[0018] 4. When the embedded rod is reset and the connector is inserted into the connecting hose, the conveying plate is driven by the second spring to automatically spray the disinfectant in the liquid accumulation tank through multiple sets of through holes on the spray ring to the area of ​​the three-way connecting hose, the surface of the drainage pipe connector and the rear end area of ​​the connector, so as to perform immediate and comprehensive sterilization treatment on the connection parts.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-2 An adjustable fixing device for a drainage tube in this embodiment includes a base 1, and a Velcro assembly 2 is fixedly connected to the top of the base 1. When in use, the Velcro assembly 2 can be tied to the crossbar next to the bed, and the base 1 can be fixed in the bed area by the Velcro assembly 2. Please see Figures 1-2 The side wall of the base 1 is fixedly connected to one end of the telescopic rod 3, and the other end of the telescopic rod 3 is connected to the mating component 5. The telescopic rod 3 can connect and restrict the two sets of base 1 together. Please see Figure 1 The bottom of the base 1 is fixedly connected to a hook 4. The component 5 consists of the base 1, the Velcro group 2 and the hook 4. The two sets of hooks 4 can be used to hang the bag, and then the drainage bag is placed inside the bag for use. Please see Figures 1-2 The side wall of the telescopic rod 3 is detachably connected to the deformation frame 6. The telescopic rod 3 is rotatably connected to a screw, which is threadedly connected to the side wall of the deformation frame 6, so that the deformation frame 6 can be separated from the base 1. Specifically, the upper end of the deformation frame 6 is detachably connected to the adjustment frame 61; More specifically, the end of the deformation frame 6 is inserted into the groove provided on the side wall of the adjustment frame 61, so that the deformation frame 6 and the adjustment frame 61 are connected and form a snap-fit, which facilitates the subsequent disassembly and connection between the adjustment frame 61 and the deformation frame 6. Thus, the device can be divided into three connecting parts, namely the deformation frame 6, the adjustment frame 61 and the base 1. The three connecting parts can be used individually or connected. For example, the deformation frame 6 can be bent into various shapes when subjected to force. In use, the drainage tube can be placed inside the deformation frame 6, and then the deformation of the deformation frame 6 can allow the drainage tube to be placed on the hospital bed according to a specific route. More specifically, the upper end of the deformable frame 6 is hollowed out and connected to the hollow area inside the deformable frame 6; For example, the deformable frame 6 is made of flexible metal tubing, similar to the bendable, shape-retaining rod on a mobile phone holder.

[0023] Please see Figure 8The upper end of the adjustment frame 61 is rotatably connected to the baffle plate 7 via a torsion spring. When in use, the baffle plate 7 returns to its original position and contacts the adjustment frame 61, enclosing the upper area of ​​the adjustment frame 61. When the drainage tube needs to be replaced, the baffle plate 7 is driven by the embedded rod 9 and unfolds, which facilitates the placement of the drainage tube and the subsequent delivery of disinfectant liquid to the connection between the drainage tube and the connecting hose. During disinfection, the adjustment frame 61 is in a relatively closed state. Please see Figure 8 The bottom of the adjustment frame 61 is provided with a sliding groove 8, and an embedded rod 9 is slidably connected in the sliding groove 8. The other end of the embedded rod 9 is slidably inserted into the guide frame 10. A first spring is fixedly connected in the guide frame 10, and the other end of the first spring is fixedly connected to the embedded rod 9. The first spring can provide power for the movement and reset of the embedded rod 9. A drive pull rope 11 is fixedly connected to the side wall of the embedded rod 9. One end of the drive pull rope 11 slides through the side wall of the guide frame 10, and the other end of the drive pull rope 11 is fixedly connected to the side wall of the baffle plate 7. For example, during use, the user applies a pulling force to the insert rod 9, causing the insert rod 9 to move. The insert rod 9 then applies a pulling force to drive the pull rope 11 to move, and the pull rope 11 drives the cover plate 7 to unfold, causing the upper end of the adjustment frame 61 to unfold.

[0024] Please see Figures 4-6 The top of the embedding rod 9 is fixedly connected to the bottom of the embedding plate 18 and drives the embedding plate 18 to slide and connect with the inner wall of the adjustment frame 61. When the embedding rod 9 is pulled, the embedding plate 18 can be moved away from the channel 12, which is a preparation for the connection of the drainage tube. Specifically, the adjustment frame 61 is provided with a channel 12 for inserting a connecting hose that is connected to the tee. The inner side wall of the channel 12 is provided with an air bladder 121. When the drainage tube is replaced, the air bladder 121 can expand and squeeze the surface of the connecting hose, so that the connecting hose is squeezed and closed.

[0025] Please see Figures 4-6 An outer cylinder 13 is fixedly connected inside the adjusting frame 61, and an inner cylinder 14 is slidably connected inside the outer cylinder 13. The side wall of the inner cylinder 14 is fixedly connected to the first driving member 15, and the first driving member 15 drives the second driving member 16 to move through the transmission member 17. Specifically, the first driving member 15 and the second driving member 16 respectively mesh with the two ends of the transmission member 17; Specifically, the second driving member 16 is fixedly connected to the side wall of the embedded plate 18; Specifically, the output end of the outer cylinder 13 is connected to the inside of the airbag 121. When the air inside the outer cylinder 13 is compressed, the air can be delivered to the inside of the airbag 121, which will cause the airbag 121 to expand as a whole. For example, when the connecting hose of the tee is connected to the upper connector of the drainage tube, the connector is inserted into the connecting hose and squeezes the connecting hose, so that the connector is pressed against the side wall of the channel 12, thereby improving the tightness of the connection between the connector and the connecting hose.

[0026] Please see Figure 6 The adjustment frame 61 has an embedded plate 18 with a spray ring 19 at both the front and rear ends. The spray ring 19 is divided into multiple segments and the multiple segments of the spray ring 19 are connected by a hose. The spray ring 19 is hollow inside and has multiple sets of through holes on the inner side wall. The spray ring 19 is connected to the one-way valve on the conveying trough 193 through a diversion pipe. In addition, the two sets of spray rings 19 located in the unfolded area of ​​the shield 7 are not connected, and the spray rings 19 are arranged in an arc shape when the shield 7 is unfolded. Please see Figures 6-7 Inside the adjustment frame 61, a winding drum 20 is rotatably connected via a torsion spring. A traction rope 22 is wound on the winding drum 20. The other end of the traction rope 22 is fixedly connected to the embedded plate 18. When the embedded plate 18 moves, the traction rope 22 pulls the traction rope 22 and causes the winding drum 20 to rotate. The winding drum 20 drives the absorption plate 21 to reset and rotate. The absorption plate 21 is located in the end area of ​​the channel 12. Specifically, the winding cylinder 20 is connected to the lower end of the absorbent plate 21. Absorbent paper is attached to the absorbent plate 21 via Velcro, which facilitates the absorption of liquid. The absorbent paper will be removed and replaced with a new absorbent paper later.

[0027] Please see Figure 2 An auxiliary frame 191 is fixedly connected to the side wall of the adjusting frame 61. The upper and lower ends of the auxiliary frame 191 are respectively provided with a liquid accumulation tank 192 and a conveying tank 193. The liquid accumulation tank 192 and the conveying tank 193 are connected by a one-way valve. The auxiliary frame 191 is provided with a replenishment pipe, which is connected to the liquid accumulation tank 192, so that the liquid accumulation tank 192 can be replenished through the replenishment pipe. The conveying trough 193 is slidably connected to a conveying plate 194. One end of the conveying plate 194 is slidably inserted into a limiting frame 195. A second spring is fixedly connected inside the limiting frame 195. One end of the second spring is fixedly connected to the side wall of the conveying plate 194. The side wall of the conveying plate 194 is fixedly connected to a power component 196. The other end of the power component 196 slides through the side wall of the auxiliary frame 191 and is fixedly connected to the embedded rod 9. Specifically, the power component 196 is a pull rope; Specifically, the first driving member 15 and the second driving member 16 are racks, and the transmission member 17 is a gear. In use, the base 1 is fixed to the side of the bed by the Velcro assembly 2 or the base 1 can be separated from the deformable frame 6; when connecting the drainage tube to the connecting hose of the three-way connector on the patient, a thrust is applied in advance to push the embedding rod 9, the embedding rod 9 drives the drive rope 11 to move, the drive rope 11 pulls the cover plate 7 to unfold, so that the upper part of the adjustment frame 61 unfolds, and at the same time the embedding rod 9 drives the embedding plate 18 to move outward; At the same time, the embedded plate 18 drives the traction rope 22 to move, and the traction rope 22 drives the absorption plate 21 to rotate to the end of the channel 12. The absorption plate 21 contacts the end of the connecting hose of the three-way connector, so that the connecting hose is closed when squeezed by the air bag 121, and the liquid flowing out of the end of the connecting hose is absorbed by the absorption plate 21. At the same time, when the embedded plate 18 moves, it drives the second driving member 16 to move. The second driving member 16 drives the first driving member 15 through the transmission member 17 to move the inner cylinder 14 inward and squeeze the air in the outer cylinder 13 into the inflation bag 121. The inflation bag 121 expands and squeezes the end of the connecting hose of the three-way connector. Simultaneously, the embedded rod 9 pulls the power component 196 to move, the power component 196 pulls the conveying plate 194 to move outward, and the conveying plate 194 draws the disinfectant liquid in the liquid accumulation tank 192 into the conveying tank 193, in preparation for the disinfection of the connecting hose and the upper end of the drainage pipe of the subsequent three-way connector. Then the drainage tube is passed through the deformation frame 6 and into the adjustment frame 61. It then passes through the first set of spray rings 19. The conical connector of the drainage tube is then placed on the embedding plate 18, so that the conical connector and the embedding plate 18 are engaged. Then the pull on the embedding rod 9 is released, and the embedding rod 9 moves back to its original position with the assistance of the first spring. The embedding rod 9 drives the embedding plate 18 to move back to its original position. When the drive rope 11 loses its tension on the baffle plate 7, the baffle plate 7 resets and closes the opening at the top of the adjustment frame 61. When the embedded plate 18 loses its tension on the traction rope 22, the absorption plate 21 is reset and rotated by the torsion spring and moves away from the channel 12 area. The outer cylinder 13 resets and moves. The inflatable bladder 121 loses its compression on the connecting hose of the three-way connector. The embedded plate 18 drives the connector to move forward and insert into the channel 12 and into the connecting hose to communicate with it. At the same time, the conveyor plate 194 delivers the disinfectant liquid to the two sets of spray rings 19 with the assistance of the second spring, and sprays the liquid outward to the connecting hose area of ​​the three-way connector and the connector surface and rear end area of ​​the drainage tube connector, and sterilizes the connecting area. After the connection is completed, the deformation frame 6 can be twisted according to the actual situation to deform the deformation frame 6. The deformation frame 6 will restrict the drainage tube in the bed area according to the generated shape, and the deformation frame 6 can prevent external objects from pressing on the surface of the drainage tube.
