Description

Technical Field

[0001] This invention relates to the field of drainage tube technology, specifically to a medical drainage tube that facilitates flow rate adjustment. Background Technology

[0002] In the medical field, medical drainage tubes are commonly used medical devices, widely applied in various medical scenarios such as drug delivery and body fluid drainage. However, existing medical drainage tubes have several problems in practical use, as follows:

[0003] Insufficient protective performance: Traditional medical drainage tubes are usually single-layered and lack effective protective measures. During medical procedures, the drainage tube is easily subjected to external forces such as squeezing and impact, which can cause the tube to deform or even rupture, thus affecting the normal delivery of medication or the smooth drainage of bodily fluids. In severe cases, this may adversely affect the patient's treatment and recovery.

[0004] Poor flexural strength: Due to limitations in the material and structure of the drainage tube, it is prone to bending during use. Once the drainage tube bends, it can lead to narrowing or blockage of the lumen, causing obstruction of drug flow or preventing normal drainage of bodily fluids, affecting the treatment effect, and may even lead to medical accidents.

[0005] Inconvenient flow regulation: Existing flow regulation methods for drainage tubes are relatively simple, making it difficult to achieve multi-level, precise flow control. In some medical scenarios requiring precise control of drug delivery speed or body fluid drainage volume, traditional flow regulation methods cannot meet clinical needs, posing certain difficulties for medical operations.

[0006] Medication solution temperature maintenance: In low-temperature environments, the temperature of the medication delivered through the infusion tube is low, and direct injection into the patient may cause discomfort such as chills and vasoconstriction, affecting the patient's treatment experience and recovery process. Most existing medical infusion tubes do not have medication solution temperature maintenance capabilities, thus failing to solve this problem.

[0007] The issue of component recycling: Currently, most medical drainage tubes are single-use products, discarded after use. This not only wastes resources but also increases medical costs. Meanwhile, if some components used with drainage tubes, such as kits with specific functions, could be recycled, it would help reduce medical costs and the generation of medical waste. Summary of the Invention

[0008] The purpose of this invention is to provide a medical drainage tube that is easy to adjust the flow rate, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a medical drainage tube with easy flow adjustment, comprising a drainage tube body, an installation sleeve fitted on the outer side of the drainage tube body, protective outer tubes on both sides of the installation sleeve, the protective outer tubes fitted on the outer side of the drainage tube body, a connecting ring one and a connecting ring two fixed at both ends of the installation sleeve respectively, the connecting ring one and the connecting ring two being located between the two protective outer tubes, a connecting strip fixed between the protective outer tubes and the drainage tube body, multiple sets of clamping blocks inserted into the surface of the installation sleeve, the multiple sets of clamping blocks increasing in height from left to right, a push ring fitted on the inner side of the installation sleeve, the push ring pushing the clamping blocks, the clamping blocks clamping the drainage tube body, heating components embedded in the inner sides of the connecting ring one and the connecting ring two, the heating components keeping the liquid medicine transported inside the drainage tube body warm.

[0010] Preferably, there are multiple connecting strips, which are distributed circumferentially around the guide tube body. The connecting strips and the protective outer tube are of equal length, and the mounting sleeve is an "I"-shaped round tube with an inner diameter smaller than the outer diameter of the protective outer tube.

[0011] Preferably, the first connecting ring is an L-shaped circular plate, and the second connecting ring is an inverted L-shaped circular plate. A rubber cover is fixed to one end of the first connecting ring near the mounting sleeve, and a rubber ring is fixed to one end of the rubber cover. The rubber ring is fitted in the first limiting groove, which is located on the outer ring surface of the second connecting ring. After the rubber cover is unfolded, it wraps around the mounting sleeve.

[0012] Preferably, a limiting groove 2 is provided at one end of the mounting sleeve near the connecting ring 1. The limiting groove 2 is an annular groove. After the rubber cover is folded and inserted between the connecting ring 1 and the mounting sleeve, the rubber ring is fitted in the limiting groove 2. A rubber sealing ring is fixed on the plate of the connecting ring 1, and one end of the rubber sealing ring abuts against one side of the mounting sleeve.

[0013] Preferably, the surface of the mounting sleeve has multiple sets of sockets, which are circumferentially distributed around the central axis of the guide tube body. The clamping blocks and the sockets correspond one-to-one. The end of the clamping block away from the guide tube body has an inclined surface. The surface of the clamping block has a through hole, and a rubber band is inserted into the through hole. The rubber band is fixed between two parallel side walls of the through hole. Side grooves are provided on both sides of the clamping block.

[0014] Preferably, the push ring is an "I"-shaped round tube, and the inner ring surface of the push ring has a groove, which is an annular groove. Multiple rubber rings are fixed on the tube body of the mounting sleeve, and the outer diameter of the rubber rings is larger than the inner ring diameter of the mounting sleeve.

[0015] Preferably, the outer ring surface of the push ring is provided with an anti-slip groove, the anti-slip groove is annular, and there are multiple anti-slip grooves, which are arranged along the long side of the mounting sleeve.

[0016] Preferably, both the inner ring openings of the first connecting ring and the second connecting ring are provided with embedded grooves, which are annular grooves. The heating component is installed in the embedded grooves, and multiple pressure relief holes are provided on one side of the embedded grooves.

[0017] Preferably, the heating assembly includes a heating wire and a silicone guide ring. Two limiting ribs of different sizes are fixed on each of the two parallel sidewalls of the embedded groove. The heating wire is located between the four limiting ribs. The silicone guide ring is fixed at the opening of the embedded groove, and the inner ring surface of the silicone guide ring is in contact with the outer wall of the guide tube body.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention proposes a medical drainage tube with easily adjustable flow rate. It features a protective outer tube attached to the outside of the drainage tube body, secured to the body by multiple connecting strips, forming a double-layered pipe structure. The protective outer tube effectively protects the drainage tube body, withstanding a certain degree of external pressure and impact, preventing direct damage. Simultaneously, the space between the protective outer tube and the drainage tube body acts as a buffer, further enhancing the drainage tube's impact resistance. The connecting strips not only connect the protective outer tube and the drainage tube body but also provide support, strengthening the drainage tube's resistance to bending. During use, even if the drainage tube is subjected to bending forces, the connecting strips effectively prevent excessive bending, ensuring smooth flow of medication or bodily fluids and avoiding problems such as medication obstruction or poor drainage caused by tube bending.

[0020] Multiple sets of clamps, increasing in height from left to right, are inserted into the surface of the mounting sleeve. By moving the push ring and pushing the corresponding clamps to hold the guide tube body, different degrees of necking of the guide tube body can be achieved, thus creating multiple levels of flow rate adjustment. Pushing the clamps of different lengths with the push ring causes different ranges of necking in the guide tube body, thereby achieving precise control of the flow rate at multiple levels and meeting the precise control requirements for drug delivery speed or body fluid drainage volume in different medical scenarios. Furthermore, the groove on the inner ring of the push ring cooperates with the rubber ring on the mounting sleeve body, increasing the resistance between the mounting sleeve and the push ring, effectively preventing the push ring from sliding freely, ensuring that the necking range of the guide tube body remains stable, and further improving the accuracy and reliability of flow rate adjustment.

[0021] Heating components, including heating wires and silicone guide rings, are embedded inside both connecting ring one and connecting ring two. In low-temperature environments, a miniature power supply module installed inside connecting ring one and connecting ring two provides power to the heating wires. The heat generated by the heating wires heats the silicone guide rings, which then wrap around the guide tube body, thus keeping the medication delivered inside the guide tube warm. This prevents discomfort caused by injecting low-temperature medication into the patient, improving the patient's treatment experience and recovery outcome. Simultaneously, multiple pressure relief holes on one side of the embedded groove allow for timely pressure relief, ensuring the heating components function properly.

[0022] The mounting sleeve is a detachable structure attached to the main body of the drainage tube. The main body is disposable, while the mounting sleeve is reusable. After use, the main body of the drainage tube can be simply cut off on one side of the mounting sleeve, and then the mounting sleeve can be removed and sterilized for reuse. This design not only reduces medical costs but also reduces the generation of medical waste, meeting the requirements of environmental protection and sustainable development.

[0035] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0036] Please see Figures 1 to 11 This invention provides a technical solution: a medical drainage tube that facilitates flow adjustment, comprising a drainage tube body 1, an installation sleeve 4 sleeved on the outer side of the drainage tube body 1, and protective outer tubes 2 on both sides of the installation sleeve 4. The protective outer tubes 2 are sleeved on the outer side of the drainage tube body 1. Connecting ring 1 5 and connecting ring 2 6 are fixed at both ends of the installation sleeve 4 respectively. The connecting ring 1 5 and connecting ring 2 6 are located between the two protective outer tubes 2. Connecting strips 3 are fixed between the protective outer tubes 2 and the drainage tube body 1. There are multiple connecting strips 3, which are circumferentially distributed around the drainage tube body 1. The connecting strips 3 and the protective outer tubes 2 are of equal length. The installation sleeve 4 is an "I"-shaped circular tube, and the inner diameter of the installation sleeve 4 is smaller than the outer diameter of the protective outer tube 2. The protective outer tube 2 is fixed to the guide tube body 1 by the connecting strip 3. The protective outer tube 2 and the guide tube body 1 form a double-layer pipe. The protective outer tube 2 protects the guide tube body 1, and the space between the protective outer tube 2 and the guide tube body 1 acts as a buffer to prevent the guide tube body 1 from being directly squeezed. In addition, the connecting strip 3 not only connects the guide tube body 1 and the protective outer tube 2, but also improves the bending resistance of the guide tube body 1, preventing the guide tube body 1 from bending during use and causing the liquid to flow back.

[0037] Connecting ring 5 is an L-shaped annular plate, and connecting ring 6 is an inverted L-shaped annular plate. A rubber cover 17 is fixed to one end of connecting ring 5 near the mounting sleeve 4. A rubber ring 19 is fixed to one end of the rubber cover 17 and is fitted in a limiting groove 18. The limiting groove 18 is located on the outer ring surface of connecting ring 6. When the rubber cover 17 is unfolded, it wraps around the mounting sleeve 4. A limiting groove 20 is located at one end of the mounting sleeve 4 near connecting ring 5. The limiting groove 20 is annular. After the rubber cover 17 is folded and inserted between connecting ring 5 and mounting sleeve 4, the rubber ring 19 is fitted in the limiting groove 20. A rubber sealing ring 21 is fixed to the plate body of connecting ring 5, and one end of the rubber sealing ring 21 abuts against one side of the mounting sleeve 4. The mounting sleeve 4 is a detachable structure on the guide tube body 1, meaning it can be reused. Since the guide tube body 1 is a disposable structure, after use, the guide tube body 1 is cut off on one side of the mounting sleeve 4, and then the mounting sleeve 4 is removed and disinfected. When storing the mounting sleeve 4, the rubber cover 17 is pulled out from between the mounting sleeve 4 and the connecting ring 5, and the anti-slip groove 16 is fitted into the limiting groove 18. At this time, the rubber cover 17 wraps around the mounting sleeve 4, protecting it. After the mounting sleeve 4 is installed on the guide tube body 1, when the position of the push ring 13 is adjusted, the rubber cover 17 is also unfolded to prevent the push ring 13 from being accidentally touched. When the rubber cover 17 is not needed, the rubber sealing ring 21 is turned outward, the rubber cover 17 is inserted between the mounting sleeve 4 and the connecting ring 5, and the rubber ring 19 is pushed into the limiting groove 20 for limiting. The rubber sealing ring 21 is then turned back to seal the groove between the mounting sleeve 4 and the connecting ring 5.

[0038] Multiple sets of clamping blocks 8 are inserted into the surface of the mounting sleeve 4, with the height of the clamping blocks 8 increasing from left to right. Multiple sets of insertion ports 7 are formed on the surface of the mounting sleeve 4, arranged circumferentially around the guide tube body 1. Each clamping block 8 corresponds to one insertion port 7. The end of each clamping block 8 away from the guide tube body 1 has a bevel 12. A through-hole 9 is formed on the surface of each clamping block 8, and a rubber band 10 is inserted into the through-hole 9. The rubber band 10 is fixed between two parallel sidewalls of the through-hole 9. Side grooves 11 are formed on both sides of each clamping block 8. A push ring 13 is fitted inside the sleeve 4. After the push ring 13 pushes the clamping block 8, the clamping block 8 clamps the guide tube body 1. The push ring 13 is an "I" shaped round tube. A groove 14 is opened on the inner ring surface of the push ring 13. The groove 14 is an annular groove. Multiple rubber rings 15 are fitted and fixed on the tube body of the sleeve 4. The outer diameter of the rubber rings 15 is larger than the inner ring diameter of the sleeve 4. An anti-slip groove 16 is opened on the outer ring surface of the push ring 13. The anti-slip groove 16 is an annular groove. Multiple anti-slip grooves 16 are provided and are arranged along the long side of the sleeve 4. Multiple sets of clamps 8 constitute multiple levels for adjusting the flow rate of the guide tube body 1. Specifically, by moving the push ring 13 to push the corresponding clamps 8, the guide tube body 1 is clamped, achieving different degrees of necking of the tube body 1. This allows for multi-level flow rate adjustment of the guide tube body 1. When the push ring 13 pushes the short-length clamps 8, the necking range of the guide tube body 1 is small. When the push ring 13 pushes the medium-length clamps 8, the necking range of the guide tube body 1 is further limited. When the push ring 13 pushes the long-length clamps 8, the flow rate of the guide tube body 1 after necking is minimal. This adjustment is achieved by pushing the push ring 13... The system allows for precise control of multiple flow levels. The rubber ring 15 is clamped between the mounting sleeve 4 and the push ring 13, increasing the resistance between them and preventing the push ring 13 from sliding arbitrarily, which could cause the necking range of the guide tube body 1 to change. It should be noted that when the push ring 13 pushes the clamping block 8 along the inclined surface 12, the clamping block 8 moves in the direction of the guide tube body 1, and the clamping block 8 stretches the rubber band 10 to deform. If the push ring 13 is pulled and the push ring 13 and the clamping block 8 are misaligned, the rebound force of the rubber band 10 will pull the clamping block 8 back, and the clamping block 8 will no longer clamp the guide tube body 1.

[0039] Heating components are embedded in the inner sides of both connecting ring 5 and connecting ring 6, which keep the liquid medicine transported inside the guide tube body 1 warm. The inner ring openings of both connecting ring 5 and connecting ring 6 are provided with an embedded groove 22, which is an annular groove. The heating components are installed in the embedded groove 22, and multiple pressure relief holes 25 are provided on one side of the embedded groove 22. The heating components include a heating wire 23 and a silicone guide ring 24. Two limiting ribs 26 of different sizes are fixed on the two parallel side walls of the embedded groove 22. The heating wire 23 is located between the four limiting ribs 26. The silicone guide ring 24 is fixed at the groove opening of the embedded groove 22, and the inner ring surface of the silicone guide ring 24 is in contact with the outer wall of the guide tube body 1. An existing micro power supply module (which can be a button battery) is installed inside the connecting ring 5 and the connecting ring 6. The micro power supply module provides power to the heating wire 23. The heat generated by the heating wire 23 heats the silicone guide ring 24. The silicone guide ring 24 is wrapped around the guide tube body 1. In a low-temperature environment, the heating wire 23 and the silicone guide ring 24 keep the liquid medicine delivered inside the guide tube body 1 warm, so as to avoid discomfort caused by the injection of low-temperature liquid medicine into the body. The pressure relief hole 25 is used to relieve pressure on the inner groove 22.

[0040] Instructions for using the medical drainage tube with easy flow adjustment: Pass the drainage tube body 1 through the mounting sleeve 4, so that the mounting sleeve 4 is fitted over the outside of the drainage tube body 1. The mounting sleeve 4 is an "I"-shaped circular tube, the inner diameter of which is smaller than the outer diameter of the protective outer tube 2. Ensure that the protective outer tube 2 is fixed to the drainage tube body 1 by multiple connecting strips 3 distributed circumferentially around the drainage tube body 1 as the central axis. The protective outer tube 2 and the drainage tube body 1 form a double-layer pipe. The protective outer tube 2 protects the drainage tube body 1, and the space between the two acts as a buffer to prevent the drainage tube body 1 from being directly squeezed. At the same time, the connecting strips 3 improve the bending resistance of the drainage tube body 1 and prevent bending during use that could cause obstruction of the liquid flow. Connecting ring 5 and connecting ring 6 are fixed at both ends of the mounting sleeve 4, respectively. Connecting ring 5 is a circular plate with an "L"-shaped cross-section, and connecting ring 6 is a circular plate with an inverted "L"-shaped cross-section. Connecting ring 5 and connecting ring 6 are located between the two protective outer tubes 2.

[0041] Use and storage of rubber cover 17: After the mounting sleeve 4 is installed on the guide tube body 1, if it is necessary to prevent the push ring 13 from being accidentally touched, unfold the rubber cover 17 to wrap around the mounting sleeve 4. Specifically, the rubber ring 19 fixed at one end of the rubber cover 17 is removed from the limiting groove 20 (the annular groove opened at the end of the mounting sleeve 4 near the connecting ring 5), the rubber cover 17 is pulled out and unfolded between the connecting ring 5 and the mounting sleeve 4, and then the rubber ring 19 is placed in the limiting groove 18 (opened on the outer ring surface of the connecting ring 6). When storing the mounting sleeve 4, the rubber cover 17 is pulled out from between the mounting sleeve 4 and the connecting ring 5, and the anti-slip groove 16 (it is speculated that the original text "anti-slip groove 16" is incorrect and should be "rubber ring 19") is placed in the limiting groove 18. At this time, the rubber cover 17 wraps around the mounting sleeve 4 and provides protection for the mounting sleeve 4. When the rubber cover 17 is not needed, turn the rubber sealing ring 21 (fixed on the plate of the connecting ring 5, with one end abutting against one side of the mounting sleeve 4) outward, insert the rubber cover 17 between the mounting sleeve 4 and the connecting ring 5, push the rubber ring 19 into the limiting groove 20 for limiting, and finally turn the rubber sealing ring 21 back to seal the groove between the mounting sleeve 4 and the connecting ring 5.

[0042] Flow regulation: Multiple sets of clamping blocks 8 are inserted into the surface of the mounting sleeve 4, with the height of the clamping blocks 8 increasing from left to right. Multiple sets of insertion ports 7 are circumferentially distributed around the central axis of the guide tube body 1 on the surface of the mounting sleeve 4, with each clamping block 8 corresponding to one insertion port 7. One end of the clamping block 8 away from the guide tube body 1 has a bevel 12, and a through-hole 9 is opened on its surface. A rubber band 10 is inserted into the through-hole 9, and the rubber band 10 is fixed between two parallel sidewalls of the through-hole 9. Side grooves 11 are opened on both sides of the clamping block 8. A push ring 13 is fitted inside the mounting sleeve 4. The push ring 13 is an "I"-shaped cylindrical tube with an annular groove 14 on its inner surface. Multiple rubber rings 15, with an outer diameter larger than the inner ring diameter of the mounting sleeve 4, are fitted and fixed on the tube body of the mounting sleeve 4. The rubber rings 15 are clamped between the mounting sleeve 4 and the push ring 13, increasing the resistance between them and preventing the push ring 13 from sliding freely. The outer ring of the push ring 13 has multiple annular anti-slip grooves 16 arranged along the long side of the mounting sleeve 4. By moving the push ring 13, it pushes the corresponding clamping block 8 along the inclined surface 12. The clamping block 8 moves in the direction of the guide tube body 1 and clamps the guide tube body 1, realizing different degrees of necking of the guide tube body 1, thereby enabling multi-level flow rate adjustment. When the push ring 13 pushes the short-length clamping block 8, the necking range of the guide tube body 1 is small; when pushing the medium-length clamping block 8, the necking range of the guide tube body 1 is further limited; when pushing the long-length clamping block 8, the flow rate of the guide tube body 1 after necking is minimal. If the push ring 13 is pulled back, causing the push ring 13 and the clamping block 8 to misalign, the rebound force of the rubber band 10 pulls the clamping block 8 back, and the clamping block 8 no longer clamps the guide tube body 1.

[0043] Medicine solution insulation: Heating components are embedded inside both connecting ring 5 and connecting ring 6 to keep the medicine solution transported inside the guide tube body 1 warm. Both connecting ring 5 and connecting ring 6 have annular grooves 22 at their inner openings. The heating components are installed in the grooves 22, and multiple pressure relief holes 25 are provided on one side of the grooves 22 for pressure relief. The heating components include a heating wire 23 and a silicone guide ring 24. Two limiting ribs 26 of different sizes are fixed on the two parallel sidewalls of the groove 22. The heating wire 23 is positioned between the four limiting ribs 26. The silicone guide ring 24 is fixed at the opening of the groove 22, and its inner surface contacts the outer wall of the guide tube body 1. An existing micro power supply module (which can be a button battery) is installed inside the connecting ring 5 and the connecting ring 6. The micro power supply module provides power to the heating wire 23. The heat generated by the heating wire 23 heats the silicone guide ring 24. The silicone guide ring 24 is wrapped around the guide tube body 1. In a low-temperature environment, it keeps the liquid medicine delivered inside the guide tube body 1 warm and avoids discomfort caused by the injection of low-temperature liquid medicine into the body.

[0044] Post-use processing: Since the guide tube body 1 is a disposable structure, and the mounting sleeve 4 is a detachable and reusable structure, after the guide tube body 1 is used, cut it off on one side of the mounting sleeve 4, and then remove the mounting sleeve 4 for disinfection so that it can be reused later.
