Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a fixing device for medical drainage tubes. Background Art

[0002] After some surgical operations, patients need to retain drainage tubes, such as abdominal drainage tubes, closed thoracic drainage tubes, T-tubes, pelvic drainage tubes, anal tubes, and urinary catheters, etc. In order to ensure the patency of the drainage tubes, medical drainage tube fixing devices have emerged as the times require. A medical drainage tube fixing device is a device specifically designed to fix drainage tubes. By providing a stable fixing effect, it ensures that the drainage tubes do not move or slide, thereby maintaining the normal operation of the drainage system. With the progress of materials science and design technology, the clinical requirements for the reliability, convenience, comfort, and disinfection convenience of medical drainage tube fixing devices have become higher, prompting existing technical solutions to improve the fixing effect, reduce the risk of infection, and reduce patient discomfort through innovative structural design and functional integration, so as to meet the core requirements of modern medicine for the safety, efficiency, and humanization of drainage tube fixing devices.

[0003] In the prior art, the fixing methods of drainage tubes mostly use simple means such as tapes and ropes, which have problems such as poor fixing effect, easy detachment, and inconvenient disassembly. These problems not only affect the comfort of patients, but also may cause the displacement and blockage of drainage tubes, and even lead to complications such as infection, seriously affecting the rehabilitation process of patients.

[0004] In summary, in the prior art, the fixing means of using tapes and ropes to fix drainage tubes are simple, which may cause problems such as the displacement and blockage of drainage tubes, and even lead to complications such as infection, seriously affecting the rehabilitation process of patients. This problem has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a medical drainage tube fixing device. Summary of the Invention

[0005] To solve the above problems, the present invention provides a medical drainage tube fixing device. Through the meshing action of the first rack, the second rack, and the clamping gear in the clamping assembly, the stable transmission of the moving plate is ensured, so that the drainage tube is firmly clamped through the clamping rod and the clamping block, reducing the pain caused by the movement of the drainage tube when the patient moves.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A medical drainage tube fixing device includes a support ring and a fixing belt. A plurality of snap buttons are fixedly connected to both ends of the fixing belt. Fixing components for fixing the drainage tube are provided on both the support ring and the fixing belt. An adjusting component for adjusting the size of the support ring is provided on the support ring, and the adjusting component is located below the fixing component. A stabilizing component for improving the fixing performance of the fixing belt is provided on the fixing belt, and the stabilizing component is located below the fixing component.

[0007] The fixing component includes a housing, the inner side wall of the housing is fixedly connected with a bottom plate, the top of the bottom plate is symmetrically provided with first sliding grooves, and a clamping component is arranged on the bottom plate.

[0008] The clamping component includes a first rack and a second rack that are horizontally slidably matched with the top of the bottom plate. The first rack and the second rack are both located in the first sliding groove adjacent to them. A clamping gear is rotatably matched with the top of the bottom plate. The first rack and the second rack are both meshed with the clamping gear. The side walls of the first rack and the second rack are both fixedly connected with moving plates. One side of the first rack away from the moving plate is fixedly connected with a pushing and pulling block. One side of the pushing and pulling block is fixedly connected with a pushing and pulling rod. The pushing and pulling rod penetrates through the side wall of the housing and extends to the outside of the housing and is fixedly connected with a pushing and pulling plate. A through groove is opened on the top wall of the housing. The upper parts of the moving plates are both horizontally slidably matched with the housing through the through groove. The upper parts of the side walls of the moving plates are both fixedly connected with clamping rods. One end of the clamping rod away from the moving plate is fixedly connected with a clamping block.

[0009] A dredging component is arranged on the top of the clamping gear for dredging the drainage tube when the drainage tube is blocked. A limiting component is arranged on the top of the housing for limiting the dredging component. The limiting component is located above the dredging component.

[0010] The technical principle of the above scheme is as follows:

[0011] Medical staff fix the fixing belt at the position of the patient's wound through the snap fastener, improve the fixing performance of the fixing belt through the stabilizing component, and wear the support ring on the patient's limb. The size of the support ring is controlled through the adjusting component and it is firmly fixed on the patient's limb. Then, the drainage tube is passed through the fixing component located on the support ring and the fixing belt.

[0012] Medical staff push the pushing and pulling plate, which drives the pushing and pulling rod, the pushing and pulling block and the first rack to move horizontally in sequence. The first rack drives the clamping gear to rotate, and the clamping gear drives the second rack to move horizontally, so that the first rack and the second rack drive the moving plates adjacent to them to approach each other respectively. Furthermore, the moving plates drive the clamping rods and the clamping blocks adjacent to them to approach each other respectively to clamp the drainage tube.

[0013] When the drainage tube is blocked, the patient can pull out the pushing and pulling plate by himself. At this time, the pushing and pulling plate drives the pushing and pulling rod, the pushing and pulling block and the first rack to move horizontally in sequence. The first rack drives the clamping gear to rotate and drives the dredging component to operate to dredge the drainage tube. During this process, the limiting component will limit the movement range of the dredging component.

[0014] The above scheme has the following beneficial effects:

[0015] 1. In the present invention, through the meshing action of the first rack, the second rack and the clamping gear in the clamping assembly, the stable transmission of the moving plate is ensured, so that the drainage tube is firmly clamped through the clamping rod and the clamping block, reducing the pain caused by the movement of the drainage tube when the patient moves. Compared with the prior art in which fixed tapes and fixed ropes are used to fix the drainage tube, this solution clamps the drainage tube through a mechanical structure of gear-rack meshing, enabling it to clamp the drainage tube more firmly, thus ensuring the stability of the clamping.

[0016] 2. In the present invention, when the drainage tube becomes blocked, the dredging assembly can effectively dredge it, thus ensuring the smooth progress of drainage and improving the drainage efficiency. Compared with the prior art in which medical staff need to go to the scene to deal with it when the drainage tube is blocked, and even perform the operation of reinserting the drainage tube, the fixing device in this solution can dredge the drainage tube without removing it, making the drainage process more convenient, and the patient can operate the fixing device by himself to perform the dredging operation, reducing the burden on medical staff. At the same time, since the fixing device in this solution can realize the dredging operation of the drainage tube, compared with the need to reinsert the drainage tube in the prior art, this solution does not require reinstallation of the drainage tube, reducing the harm to the patient while simplifying the operation process of the drainage tube.

[0017] 3. In the present invention, through the design of limiting the dredging assembly by the limiting component, the fixing device is more stable and reliable in structure, effectively avoiding the excessive movement of the dredging assembly during operation, thus making the drainage process safer and more reliable.

[0018] Furthermore, the dredging assembly includes a threaded cylinder fixedly connected to the top of the clamping gear. The inner side wall of the threaded cylinder is in threaded fit with a screw rod. The top of the screw rod is fixedly connected to a U-shaped plate. The outer side wall of the U-shaped plate is vertically slidably fitted with the top wall of the housing through a through groove. Silicone elastic balls are fixedly connected to both inner side walls of the U-shaped plate.

[0019] Beneficial effects: When the drainage tube is blocked, through the threaded connection between the threaded cylinder and the screw rod, the screw rod can drive the U-shaped plate and the silicone elastic balls to move up and down. During the movement of the silicone elastic balls, they will squeeze and rub the outer wall of the drainage tube, thereby reducing the blockage in the drainage tube and restoring the smoothness of drainage.

[0020] Furthermore, the limiting component includes a limiting plate fixedly connected to the top of the housing. The limiting plate is located in the movement path of the U-shaped plate.

[0021] Beneficial effects: The presence of the limiting plate effectively prevents the excessive movement of the U-shaped plate when dredging the drainage tube, thereby reducing the possibility of harm to the patient caused by the excessive movement of the U-shaped plate pulling the drainage tube. Furthermore, it ensures the safety of the dredging assembly during operation.

[0022] Further, the adjusting assembly includes a gear shaft fixedly connected coaxially with the clamping gear. The gear shaft penetrates through the bottom plate and extends outside the bottom plate to be fixedly connected with an adjusting gear. A third rack and a fourth rack are slidably matched transversely at the bottom of the bottom plate. Second sliding grooves are symmetrically formed at the bottom of the bottom plate. Both the third rack and the fourth rack are located in the second sliding grooves adjacent to them, and both the third rack and the fourth rack are meshed with the adjusting gear. Both ends of the support ring are fixedly connected with the bottom of the third rack and the bottom of the fourth rack respectively.

[0023] Beneficial effects: By rotating the adjusting gear, it can drive the third rack and the fourth rack to slide in the second sliding grooves at the bottom of the bottom plate, thereby realizing the rapid adjustment of the size of the support ring. Furthermore, medical staff can easily adjust the size of the support ring according to needs to adapt to the body types of different patients, increasing the adaptability of the fixing device.

[0024] Further, the stabilizing assembly includes a breathable patch fixedly connected to the fixing belt. A plurality of breathable holes are formed in the breathable patch, and an elastic assembly for adapting to the change of the patient's body curve is arranged at the bottom of the breathable patch.

[0025] Beneficial effects: The addition of the stabilizing assembly not only improves the stability and comfort of the fixing device, but also helps to enhance the overall drainage effect. The breathable patch provides additional stability for the entire fixing device through its adhesiveness and connection with the fixing belt, and the breathable holes formed in the breathable patch contribute to skin breathing, reducing the sense of dampness and stuffiness, thereby reducing the risk of skin damage or infection.

[0026] Further, the elastic assembly includes an annular patch fixedly connected to the bottom of the breathable patch, and the material of the annular patch is selected as silicone glue.

[0027] Beneficial effects: As a high-performance material, silicone glue has excellent elasticity and resilience. This enables the annular patch to closely fit the change of the patient's body curve, ensuring the stability of the fixing belt. At the same time, the silicone glue material itself also has a certain air permeability, further reducing the sense of dampness and stuffiness between the skin and the fixing belt, and thus improving the comfort of the patient.

[0028] Further, a clamping assembly for clamping the push-pull plate is arranged on the outer side wall of the outer shell. The clamping assembly includes a fixing frame slidably matched with the outer side wall of the outer shell and a buckle fixedly connected to the outer side wall of the outer shell. One end of the fixing frame away from the outer side wall of the outer shell is detachably connected to the buckle.

[0029] Beneficial effects: The addition of the clamping assembly enables the push-pull plate to be effectively limited after moving, thereby ensuring the stable clamping of the drainage tube. At the same time, the addition of the clamping assembly also increases the operation convenience of the fixing device, and further improves the practicality and applicability of the fixing device, enabling it to better meet the needs of patients.

[0030] Furthermore, a buffer component for reducing stimulation to the wound surface of the patient is provided on the fixing belt, and the buffer component includes a hydrophilic pad fixedly connected to the inner side wall of the fixing belt.

[0031] Beneficial effects: The soft texture of the hydrophilic pad can reduce the friction between the fixation belt and the skin, thereby reducing the physical stimulation to the patient's wound surface and the risk of infection of the patient's wound surface, and providing a wound surface with an environment conducive to healing.

[0032] Furthermore, an anti-slip layer is fixedly connected to the outer side wall of the shell.

[0033] Beneficial effect: The design of the anti-slip layer can increase the friction between the shell and the user's hand, thereby preventing the fixing device from slipping or shifting during use, thereby reducing the occurrence of accidents caused by the fixing device slipping.

[0034] Furthermore, the bottom plate is in a "冂" shape, and the airbags are symmetrically fixedly connected to the bottom of the bottom plate.

[0035] Beneficial effects: The "冂"-shaped bottom plate design reserves ventilation space for the patient's skin, improving the patient's comfort. At the same time, the airbags symmetrically fixed at the bottom of the bottom plate have a good buffering effect. When the fixing device is subjected to external pressure, the airbags can buffer the pressure, thereby reducing the damage to the patient.

[0036] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Description of the Invention

[0046] The following is a further detailed description through specific embodiments:

[0047] Embodiment 1:

[0048] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 shown: The medical drainage tube fixing device includes a support ring 1 and a fixing band 2. A number of snap buttons 3 are embedded at both ends of the fixing band 2. Fixing components for fixing the drainage tube are provided on both the support ring 1 and the fixing band 2. An adjusting component for adjusting the size of the support ring 1 is provided on the support ring 1. The adjusting component is located below the fixing component. A stabilizing component for improving the fixing performance of the fixing band 2 is provided on the fixing band 2. The stabilizing component is located below the fixing component.

[0049] The fixing component includes an outer shell 4, and an anti-slip layer is fixedly adhered to the outer side wall of the outer shell 4.

[0050] The inner side wall of the outer shell 4 is welded with a bottom plate 5. First chutes are symmetrically opened at the top of the bottom plate 5. A clamping component is provided on the bottom plate 5.

[0051] The clamping assembly includes a first rack 6 and a second rack 7 that are horizontally slidably fitted to the top of the bottom plate 5. Both the first rack 6 and the second rack 7 are located in the first chute adjacent to them. A clamping gear 8 is rotatably fitted to the top of the bottom plate 5. Both the first rack 6 and the second rack 7 are meshed with the clamping gear 8. Moving plates 9 are integrally formed on the side walls of both the first rack 6 and the second rack 7. A push-pull block 10 is integrally formed on the side of the first rack 6 away from the moving plate 9. A push-pull rod 11 is integrally formed on one side of the push-pull block 10. The push-pull rod 11 penetrates through the side wall of the housing 4 and extends to the outside of the housing 4 and is welded to a push-pull plate 12. A through groove is opened on the top wall of the housing 4. The upper parts of the moving plates 9 are horizontally slidably fitted to the housing 4 through the through groove.

[0052] Clamping rods 13 are welded to the upper parts of the side walls of the moving plates 9. Clamping blocks 14 are welded to the ends of the clamping rods 13 away from the moving plates 9.

[0053] A dredging assembly for dredging the drainage tube when the drainage tube is blocked is provided on the top of the clamping gear 8. A limiting assembly for limiting the dredging assembly is provided on the top of the housing 4. The limiting assembly is located above the dredging assembly.

[0054] As Figure 3 shown, the dredging assembly includes a threaded cylinder 15 welded to the top of the clamping gear 8. A screw rod 16 is threadedly fitted to the inner side wall of the threaded cylinder 15. A U-shaped plate 17 is welded to the top of the screw rod 16. The outer side wall of the U-shaped plate 17 is vertically slidably fitted to the top wall of the housing 4 through the through groove. Silicone elastic balls 18 are fixedly adhered to both inner side walls of the U-shaped plate 17.

[0055] As Figure 1 and Figure 2 shown, the limiting assembly includes a limiting plate 19 welded to the top of the housing 4. The limiting plate 19 is located in the movement path of the U-shaped plate 17.

[0056] As Figure 5 and Figure 6 shown, the adjusting assembly includes a gear shaft 20 that is coaxially and fixedly clamped with the clamping gear 8. The gear shaft 20 penetrates through the bottom plate 5 and extends to the outside of the bottom plate 5 and is fixedly clamped with an adjusting gear 21. A third rack 22 and a fourth rack 23 are horizontally slidably fitted to the bottom of the bottom plate 5. Second chutes are symmetrically opened at the bottom of the bottom plate 5. Both the third rack 22 and the fourth rack 23 are located in the second chute adjacent to them. Both the third rack 22 and the fourth rack 23 are meshed with the adjusting gear 21.

[0057] Both ends of the support ring 1 are fixedly adhered to the bottom of the third rack 22 and the bottom of the fourth rack 23 respectively.

[0058] As Figure 7 shown, the stabilizing assembly includes a breathable patch 24 fixedly adhered to the fixing band 2. A number of breathable holes are opened on the breathable patch 24. An elastic assembly for adapting to the change of the patient's body curve is provided at the bottom of the breathable patch 24.

[0059] The elastic component includes an annular patch 25 fixedly bonded to the bottom of the breathable patch 24, and the material of the annular patch 25 is selected as silicone glue.

[0060] The specific implementation process is as follows: First, the medical staff fixes the fixing band 2 to the patient's wound through the snap button 3, so that the breathable patch 24 and the annular patch 25 are attached to the patient's skin to complete the fixation of the fixing band 2. Subsequently, the medical staff wears the support ring 1 on the patient's limb according to the predetermined path of the drainage tube and installs the drainage tube. During this process, thanks to the design of the anti-slip layer, the medical staff can pick up the fixing device more stably when installing it, reducing the possibility of the fixing device slipping off.

[0061] As Figure 3 and Figure 4 shown, the medical staff pushes the push-pull plate 12 towards the inside of the housing 4, which in turn drives the push-pull rod 11, the push-pull block 10 and the first rack 6 to move horizontally. The first rack 6 drives the clamping gear 8 to rotate clockwise, and the clamping gear 8 drives the second rack 7 to move horizontally. At this time, the first rack 6 and the second rack 7 respectively drive the adjacent moving plates 9 to move horizontally, making them approach each other. The moving plates 9 respectively drive the adjacent clamping rods 13 and clamping blocks 14 to approach each other to clamp the drainage tube.

[0062] In this embodiment, the initial position of the U-shaped plate 17 is on the same horizontal plane as the clamping block 14, and the screw 16 is initially located at the upper part inside the threaded barrel 15.

[0063] Since the outer side wall of the U-shaped plate 17 is vertically slidably matched with the top wall of the housing 4 through the through groove, when the U-shaped plate 17 undergoes displacement in the vertical direction, the through groove will limit it, as Figure 1 and Figure 2 shown. Also, because the screw 16 is welded to the U-shaped plate 17, when the U-shaped plate 17 is limited, the screw 16 will also be limited together. At this time, since the screw 16 is in threaded cooperation with the threaded barrel 15, and the initial position of the U-shaped plate 17 is on the same horizontal plane as the clamping block 14, the clamping block 14 is welded to the clamping rod 13, the clamping rod 13 is located at the upper part of the side wall of the moving plate 9, and the upper part of the side wall of the moving plate 9 is horizontally slidably matched with the housing 4 through the through groove. At this time, the initial position of the U-shaped plate 17 is inside the through groove, so that the U-shaped plate 17 is initially in a limited state, thereby making the screw 16 initially also in a limited state.

[0064] As Figure 4 shown, during the clockwise rotation of the clamping gear 8, it drives the threaded barrel 15 to rotate clockwise. At this time, since the screw 16 is limited, it will not rotate together with the threaded barrel 15. When the threaded barrel 15 rotates clockwise, it will drive the screw 16 to move downward, and the screw 16 drives the U-shaped plate 17 to move downward, so that the U-shaped plate 17 moves down to below the clamping block 14.

[0065] During this process, the clamping gear 8 also drives the gear shaft 20 to rotate clockwise. The gear shaft 20 drives the adjusting gear 21 to rotate clockwise. The adjusting gear 21 drives the third rack 22 and the fourth rack 23 to move horizontally, causing the two ends of the support ring 1 to approach each other, and stably fixing the support ring 1 on the patient's limb.

[0066] When the drainage tube becomes blocked, the patient pulls the push-pull plate 12 outwards towards the outside of the housing 4. At this time, the push-pull plate 12 drives the push-pull rod 11, the push-pull block 10, and the first rack 6 to move horizontally in sequence. The first rack 6 drives the clamping gear 8 to rotate counterclockwise, and the clamping gear 8 drives the threaded cylinder 15 to rotate counterclockwise. At this time, since the inner side wall of the threaded cylinder 15 is in threaded cooperation with the screw rod 16, and the outer side wall of the U-shaped plate 17 is vertically slidably engaged with the top wall of the housing 4 through the through groove, the threaded cylinder 15 drives the screw rod 16 to move upwards during the counterclockwise rotation. The screw rod 16 drives the U-shaped plate 17 to move upwards, and the U-shaped plate 17 drives the silica gel elastic ball 18 to move upwards. While the U-shaped plate 17 limits the drainage tube therein, the outer wall of the drainage tube is squeezed by the silica gel elastic ball 18, thereby dredging the drainage tube.

[0067] During the upward movement of the U-shaped plate 17, the limiting plate 19 will limit the maximum stroke of the U-shaped plate 17, reducing the pulling of the drainage tube caused by the excessive movement of the U-shaped plate 17, and further reducing the possibility of secondary injury to the patient.

[0068] Through the meshing action of the first rack 6, the second rack 7, and the clamping gear 8 in the clamping assembly of the present invention, the stable transmission of the moving plate 9 is ensured. Thus, the drainage tube is firmly clamped through the clamping rod 13 and the clamping block 14, reducing the pain caused by the movement of the drainage tube when the patient is moving. And when the drainage tube becomes blocked, the outer wall of the drainage tube is squeezed by the silica gel elastic ball 18, and the drainage tube is also dredged, ensuring the smooth progress of drainage and improving the drainage efficiency.

[0069] Embodiment 2:

[0070] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the difference from Embodiment 1 is that a clamping assembly for clamping the push-pull plate 12 is provided on the outer side wall of the housing 4. The clamping assembly includes a fixing frame 26 slidably engaged with the outer side wall of the housing 4 and a buckle 27 welded to the outer side wall of the housing 4. One end of the fixing frame 26 away from the outer side wall of the housing 4 is detachably engaged with the buckle 27.

[0071] The specific implementation process is as follows: after the push-pull plate 12 is pushed, the medical staff pushes the fixing frame 26 to engage it with the buckle 27. At this time, the push-pull plate 12 is limited by the fixing frame 26, so that it is not easily affected by external forces and moves to the outside of the shell 4, thereby limiting the first rack 6, the second rack 7 and the movable plate 9, so that the clamping rod 13 and the clamping block 14 are limited, and the drainage tube is stably clamped.

[0072] Embodiment 3:

[0073] As attached Figure 7 As shown, the difference from Example 2 is that a buffer component for reducing the stimulation to the patient's wound surface is provided on the fixing belt 2, and the buffer component includes a hydrophilic pad 28 fixedly bonded to the inner wall of the fixing belt 2.

[0074] The specific implementation process is as follows: after the medical staff fixes the fixing belt 2 to the position of the patient's wound, the hydrophilic pad 28 can provide a healing environment for the patient's wound. At the same time, the hydrophilic pad 28 is soft in texture. When the patient is moving, the friction between the patient's skin and the hydrophilic pad 28 is small, thereby reducing the physical stimulation to the patient's skin and protecting the patient's skin.

[0075] Embodiment 4:

[0076] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the difference from the embodiment 3 is that the bottom plate 5 is in the shape of a Chinese character "冂", and the airbags 29 are symmetrically fixed and bonded to the bottom of the bottom plate 5.

[0077] The specific implementation process is as follows: when the fixing device is subjected to external pressure, since the airbag 29 is located between the patient's skin and the base plate 5, the airbag 29 will buffer the external pressure, reduce the pressure on the patient's skin, and then protect the patient, so that the possibility of the patient being injured by external pressure is greatly reduced.

[0078] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
