[0002] In the medical field, medical catheters are one of the commonly used medical devices, mainly used to deliver medical liquid drugs into the patient's body. However, existing medical catheters have some shortcomings in their design and use:

[0003] Poor anti-bending performance: In clinical use, the drainage tube often causes liquid obstruction due to bending, knotting, etc., affecting the normal delivery of drugs and may even have an adverse effect on the patient's treatment.

[0004] Insufficient protection: The guide tube is easily scratched and pressed by external objects during use, causing damage or deformation of the tube wall, which in turn affects the smoothness and safety of drug delivery.

[0005] Lack of heat preservation function: In a low-temperature environment, the temperature of liquid medicine will gradually decrease when it is transported in the drainage tube, which may cause discomfort to the patient and even affect the therapeutic effect of the medicine.

[0006] Difficulty connecting and securing: When multiple catheters need to be used simultaneously, existing catheters are difficult to connect side by side conveniently and stably. Furthermore, the catheters lack effective securing methods during use, making them prone to shaking and shifting, causing inconvenience to medical staff.

[0007] The roll-up is prone to falling apart: During storage or transportation, the guide tube usually needs to be rolled into a spiral shape. However, the existing guide tube is prone to falling apart after being rolled up, which is not conducive to storage and carrying. Summary of the Invention

[0012] Preferably, the elastic protective component includes a buffer guard strip, which is an arc-shaped strip.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The medical drainage tube structure proposed in the present invention forms an anti-bending component by embedding elastic plastic strips on the medical silicone connecting strips on both sides of the inner tube, which effectively avoids the drainage tube from bending and knotting during use and ensures smooth drug delivery.

[0021] The elastic protective component (buffer strip) prevents external objects from directly contacting the inner tube, preventing scratches and damage. Furthermore, the buffer space between the buffer strip and the inner tube provides pressure resistance, preventing the inner tube from being directly pressed and causing flow interruption.

[0022] The buffer strip protects the inner tube and plays a certain role in heat preservation, slowing down the temperature drop of the liquid medicine inside the inner tube, and avoiding the low temperature of the liquid medicine in a low temperature environment affecting the patient's infusion feeling.

[0023] By providing connecting components (slots, traction bars, and clips), two sets of medical catheters can be connected side by side, facilitating the simultaneous use of multiple catheters by medical staff. Furthermore, the attachment layer on the outer surface of the buffer strip allows the catheters to be easily secured to the accompanying bed or wall, reducing shaking and displacement during use.

[0025] The medical silicone connecting strip not only connects the inner tube and the elastic protective component, but also cooperates with the elastic plastic strip to prevent the inner tube from bending. At the same time, it cooperates with the connecting clips to realize the side-by-side connection of two sets of medical drainage tubes, reflecting the design concept of functional integration and improving the overall performance and utilization efficiency of the drainage tube.

DETAILED DESCRIPTION

[0036] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1 to 9 The present invention provides a technical solution: a medical drainage tube structure, including an infusion channel for transporting medical liquid drugs, an elastic protective component is provided on the outside of the infusion channel, a buffer space is reserved between the elastic protective component and the infusion channel, and connecting components are provided on both sides of the infusion channel, the connecting components are used to connect the elastic protective component and the infusion channel, and the connecting components are used to limit the connection of two groups of medical drainage tubes after they are arranged side by side, and the connecting components also prevent the medical drainage tubes rolled into a spiral shape from dispersing.

[0038] The infusion channel includes an inner tube 1, and the connecting component includes a medical silicone connecting strip 2. The two medical silicone connecting strips 2 are respectively fixed on both sides of the inner tube 1. The lengths of the medical silicone connecting strip 2 and the inner tube 1 are equal. The surface of the medical silicone connecting strip 2 is embedded with an anti-bending component to prevent the inner tube 1 from bending when transporting medical liquid drugs, resulting in liquid obstruction; the anti-bending component includes an elastic plastic strip 5, and the top surface and the bottom surface of the medical silicone connecting strip 2 are both provided with a reserved groove 4, and the reserved groove 4 is a "U"-shaped groove. The elastic plastic strip 5 and the reserved groove 4 correspond one to one, and the elastic plastic strip 5 is fixed in the reserved groove 4. The long sides of the elastic plastic strip 5, the reserved groove 4 and the medical silicone connecting strip 2 are equal in length. The reason why the medical silicone connecting strips 2 are fixed on both sides of the inner tube 1 is to use the medical silicone connecting strips 2 to install the elastic protective component. After the elastic plastic strips 5 are installed on the upper and lower sides of the medical silicone connecting strips 2, when the medical drainage tube is in use, the two groups of elastic plastic strips 5 support the two sides of the inner tube 1, thereby preventing the inner tube 1 from getting knotted and bent, thereby preventing the inner tube 1 from causing flow obstruction due to bending. The medical silicone connecting strips 2 not only realize the connection between the inner tube 1 and the elastic protective component, but also cooperate with the elastic plastic strips 5 to achieve the anti-bending effect on the inner tube 1, that is, the medical silicone connecting strips 2 have multiple uses.

[0039] The elastic protection component includes a buffer guard strip 3, which is an arc-shaped strip. The length of the buffer guard strip 3 is equal to the length of the inner tube 1. The two ends of the buffer guard strip 3 are respectively fixed on the surface of the two medical silicone connecting strips 2. A gap is reserved between the ends of the two buffer guard strips 3. The gap is used to leak the connecting card. The connecting card is provided on the two medical silicone connecting strips 2; the connecting card includes a card slot 6, a traction strip 7 and a card strip 8. The card slot 6 is an arc-shaped groove. The card slot 6 is opened on the surface of a medical silicone connecting strip 2. The traction strip 7 It is fixed on the surface of another medical silicone connecting strip 2, and the card strip 8 is fixed on one side of the traction strip 7. The card strip 8 is a long strip with a round end face. The card strip 8 matches the card slot 6. After the two groups of medical drainage tubes are assembled side by side, the card strip 8 on one side of one group of medical drainage tubes is inserted into the card slot 6 on one side of the other group of medical drainage tubes. The long sides of the card slot 6, the traction strip 7 and the card strip 8 are equal in length; the buffer space is the gap between the inner tube 1 and the buffer guard strip 3, and the two medical silicone connecting strips 2 divide the gap between the inner tube 1 and the buffer guard strip 3 into two. After the buffer strip 3 is installed, external objects are prevented from directly contacting the inner tube 1, which not only prevents the inner tube 1 from being scratched and damaged, but also the space between the buffer strip 3 and the inner tube 1 plays a pressure-resistant role, preventing the inner tube 1 from being directly pressed and causing flow interruption; when the liquid medicine bottle connected to the inner tube 1 is kept warm by a hot water bag, the medicine inside the liquid medicine bottle is transported to the patient's body through the inner tube 1, and the buffer strip 3 protects the inner tube 1 while playing a certain role of insulation, that is, slowing down the temperature drop of the liquid medicine inside the inner tube 1, avoiding the low temperature of the liquid medicine in a low temperature environment affecting the patient's infusion feeling. The two groups of medical drainage tubes are connected by the clamping strip 8 and the clamping groove 6; and the medical drainage tubes are limited when they are coiled in a spiral shape; in this way, the medical silicone connecting strip 2 not only realizes the connection function between the inner tube 1 and the elastic protective component, but the medical silicone connecting strip 2 also cooperates with the elastic plastic strip 5 to realize the anti-bending function of the inner tube 1, and the medical silicone connecting strip 2 cooperates with the clamping groove 6, the traction strip 7 and the clamping strip 8 to realize the side-by-side connection function of the two groups of medical drainage tubes, that is, the medical silicone connecting strip 2 has multiple uses.

[0040] The outer ring surface of the buffer guard strip 3 is provided with an adhesion layer, which fixes the medical drainage tube to the accompanying bed or wall; the outer ring surface of the buffer guard strip 3 is provided with a mounting groove 9, and the adhesion layer is fixed in the mounting groove 9. Side grooves 10 are provided on both sides of the mounting groove 9. One side of the adhesion layer is provided with an anti-sticking layer, and the two sides of the anti-sticking layer extend into the two side grooves 10 respectively; the adhesion layer includes an adhesive layer 11, and the adhesive layer 11 is fixed on the surface of the mounting groove 9. The long sides of the mounting groove 9, the side groove 10 and the adhesive layer 11 are equal in length; the anti-sticking layer includes a medical release rubber strip 12, and the medical release rubber strip 12 is covered on the adhesive layer 11. Flat surfaces 14 are provided on both sides of the buffer guard strip 3, and a pick-up groove 15 is provided on the surface of the flat surface 14, and a plurality of segmented grooves 13 are provided on the outer ring surface of the medical release rubber strip 12. The curvature of the segmented groove 13 is equal to the curvature of the medical release rubber strip 12. Insert your finger into the picking groove 15 and lift up the medical release rubber strip 12 from one side. According to the use length, tear off the medical release rubber strip 12 from the matching segmented groove 13, peel off the torn medical release rubber strip 12 from the adhesive layer 11, and a part of the adhesive layer 11 leaks out. The leaked adhesive layer 11 is adhered to the wall or the accompanying bed, thereby achieving the limitation of the medical drainage tube when in use.

[0041] How to use the medical drainage tube: Connect one end of the inner tube 1 of the drainage tube to the medical liquid medicine bottle to ensure a tight connection and no liquid leakage. Place the drainage tube in a suitable position according to the actual usage scenario. Insert your fingers into the pick-up groove 15 on the flat surface 14 on both sides of the buffer guard strip 3, and lift the medical release rubber strip 12 from one side. According to the required fixed length, tear off the medical release rubber strip 12 from the matching segmented groove 13. Peel off the torn medical release rubber strip 12 from the adhesive layer 11 to allow part of the adhesive layer 11 to leak out. Bond the leaked adhesive layer 11 to the wall or the accompanying bed to achieve the limited fixation of the drainage tube. Observe the situation of the inner tube 1 transporting medical liquid medicine to ensure that the liquid flows smoothly and there is no obstruction. Because the elastic plastic strips 5 installed on the upper and lower sides of the medical silicone connecting strip 2 support both sides of the inner tube 1, knotting and bending of the inner tube 1 can be avoided. Be careful to avoid direct contact between external objects and the inner tube 1. The buffer strip 3 can play a protective role and prevent the inner tube 1 from being scratched and damaged. At the same time, the space between the buffer strip 3 and the inner tube 1 plays a compressive role to prevent the inner tube 1 from being directly pressed and causing the flow to stop. If the liquid medicine bottle connected to the inner tube 1 is kept warm by a hot water bag, the buffer strip 3 can play a certain insulation role while surrounding the inner tube 1, slowing down the temperature drop of the liquid medicine inside the inner tube 1, and avoiding the low temperature of the liquid medicine in a low-temperature environment affecting the patient's infusion feeling. Place two medical drainage tubes side by side, so that the clip 8 on one side of one group of medical drainage tubes is aligned with the clip groove 6 on the side of the other group of medical drainage tubes. Insert the clip 8 into the clip groove 6 to ensure a tight connection, so as to achieve the side-by-side connection of the two groups of medical drainage tubes. Multiple drainage tubes can be connected as needed. Fix each drainage tube after side by side according to the method of fixing a single drainage tube. Insert your fingers into the pick-up grooves 15 on the flat surfaces 14 on both sides of the buffer strip 3, and lift up the medical release rubber strip 12 from one side. According to the required fixed length, tear off the medical release rubber strip 12 from the matching segmented grooves 13, peel off the torn medical release rubber strip 12 from the adhesive layer 11, so that a part of the adhesive layer 11 leaks out, and then adhere the leaked adhesive layer 11 to the wall or the accompanying bed. Observe the situation of each inner tube 1 in the side-by-side diversion tube in transporting medical liquid drugs to ensure that the liquid flows smoothly without obstruction. Be careful to avoid direct contact between external objects and the inner tube 1. The buffer strip 3 plays a protective role. If the side-by-side diversion tube needs to be rolled into a spiral shape, the connecting clip can also play a role in preventing it from spreading. If the diversion tube is fixed to the wall or the accompanying bed, insert your fingers into the pick-up grooves 15, gently lift up the adhesive layer 11, and remove the diversion tube from the wall or the accompanying bed. If multiple guide tubes are used side by side, first separate the guide tubes connected side by side, that is, pull out the clamping strip 8 from the clamping slot 6. Remove the guide tubes from the medical liquid medicine bottle.

[0042] The difference between the medical drainage tube of the present invention and the existing drainage tube is:

[0043] Structural Composition: Existing drainage tubes typically have a simple structure, typically consisting solely of an infusion channel for transporting fluids and lacking effective protection or auxiliary connection structures. The medical drainage tube of the present invention has a more complex and comprehensive structure, comprising an infusion channel (inner tube 1), an elastic protective component (buffer strip 3), a connection component (medical silicone connection strip 2), and an adhesive layer. These components work together to form a more comprehensive drainage tube system.

[0044] Anti-bend design: Existing drainage tubes may not have a dedicated anti-bend design, making them prone to bending and kinking during use, resulting in fluid obstruction and impaired drug delivery. The medical drainage tube of the present invention features U-shaped pre-reserved grooves 4 on both the top and bottom surfaces of the medical silicone connecting strip 2, embedded with elastic plastic strips 5. These two sets of elastic plastic strips 5 support the inner tube 1 on either side, effectively preventing kinking and bending, and thus preventing flow obstruction.

[0045] Protection and buffering design: Existing drainage tubes offer limited protection for the infusion channel, making it easy for external objects to directly contact the channel, potentially causing scratches and damage. Furthermore, they lack a pressure-resistant design, potentially leading to flow interruption from direct pressure on the channel. The medical drainage tube of the present invention incorporates an elastic protective component (buffer strip 3). This arc-shaped strip is mounted on the outside of the inner tube 1, preventing direct contact with external objects and damaging the inner tube 1. Furthermore, the space between the buffer strip 3 and the inner tube 1 provides pressure resistance, preventing flow interruption from direct pressure on the inner tube 1.

[0046] Thermal insulation design: Existing medical drainage tubes generally lack thermal insulation. In low-temperature environments, the temperature of liquid medicine is low, which may affect the patient's infusion sensation. The medical drainage tube of the present invention: When the liquid medicine bottle connected to the inner tube 1 is kept warm by a hot water bag, the buffer strip 3 not only protects the inner tube 1 but also plays a certain role in thermal insulation, slowing down the temperature drop of the liquid medicine inside the inner tube 1.

[0047] Connection and Limiting Design: Existing medical drainage tubes typically lack the ability to connect multiple tubes side by side or prevent them from unraveling after coiling. The medical drainage tube of the present invention features connecting clips (clip slots 6, pull bars 7, and clip strips 8) on the medical silicone connecting strip 2. When two sets of medical drainage tubes are assembled side by side, the clip strips 8 on one set of tubes are inserted into the clip slots 6 on the other set of tubes, achieving side-by-side connection. Furthermore, the connecting clips also provide a position limit for the tubes when coiled into a spiral shape.

[0048] Fixed design: Existing drainage tubes may not have a specially designed fixing structure, making them difficult to stably fix in a specific position during use. The medical drainage tube of the present invention has an attachment layer provided on the outer annular surface of the buffer strip 3, including an adhesive layer 11 and a medical release rubber strip 12. By inserting a finger into the picking groove 15, the medical release rubber strip 12 is opened from one side, and the medical release rubber strip 12 is torn and peeled off from the matching segmented groove 13 according to the use length, so that a portion of the adhesive layer 11 leaks out. The leaked adhesive layer 11 is then bonded to the wall or the accompanying bed to achieve position limiting during use of the medical drainage tube.

[0049] The advantages of the medical drainage tube of the present invention over existing drainage tubes are as follows:

[0050] Improve the reliability of drug delivery: The anti-bending design of the medical guide tube of the present invention effectively avoids the problem of liquid flow obstruction caused by the bending of the inner tube 1, ensures that the medical liquid drug can be smoothly delivered to the patient's body, and improves the reliability of drug delivery.

[0051] Enhanced durability of the flow guide tube: The elastic protective component and buffer design not only prevent the inner tube 1 from being scratched and damaged, but also play a role in pressure resistance, thereby extending the service life of the flow guide tube and reducing the cost of use.

[0052] Improve the patient's infusion feeling: The heat preservation design can slow down the temperature drop of the liquid medicine inside the inner tube 1 in a low temperature environment, avoiding the low temperature of the liquid medicine affecting the patient's infusion feeling and improving the patient's comfort.

[0053] Easy to use and manage: The connection and limiter design allows multiple catheters to be easily connected side by side, and effectively prevents them from unraveling when rolled into a spiral shape, making it easier for medical staff to organize and manage the catheters. Furthermore, the fixed design allows the catheters to be stably fixed in a specific position, reducing shaking and displacement during use.

[0054] One thing with multiple uses and integrated functions: The medical silicone connecting strip 2 not only connects the inner tube 1 and the elastic protective component, but also cooperates with the elastic plastic strip 5 to prevent the inner tube 1 from bending. At the same time, it cooperates with the card slot 6, traction strip 7 and card strip 8 to realize the side-by-side connection of two sets of medical drainage tubes, reflecting the design concept of functional integration and improving the overall performance of the drainage tube.

[0055] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
