Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a medical drainage transfer tube. Background Technology

[0002] A drainage tube is a medical device used for clinical surgical drainage. It guides pus, blood, and other fluids accumulated between human tissues or in body cavities to the outside of the body, thereby preventing postoperative infection and accelerating wound healing. There are many types of surgical drainage tubes used in clinical medicine, some for urinary catheterization, some for wounds, some for the thoracic cavity and brain cavity, some for the gastrointestinal tract, some for the biliary tract, and so on.

[0003] Fluid drained from a drainage tube usually needs to be collected using a drainage bag. The drainage bag is generally marked with graduations. By observing the graduations on the drainage bag, the amount of fluid drained from the patient's body can be quantitatively collected. Medical staff can then conduct tests and analyses on the appropriate amount of fluid collected in the drainage bag to determine the patient's current physical condition and illness.

[0004] The use of drainage tubes is very simple. Sometimes patients or their families can operate them themselves to drain the fluid accumulated in the patient's body into a drainage bag for collection, which is very convenient. However, some existing drainage tubes and drainage bags are connected by interlocking connectors. This connection method is not very stable. When the patient accidentally pulls on the drainage tube, the connection of the drainage bag can easily come loose, causing the fluid to drip onto the patient's body and bed, thus soiling clothes and bedding, increasing the trouble of subsequent cleaning and tidying, and requiring the patient to perform drainage collection again, which increases the patient's discomfort. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a medical drainage tube to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a medical drainage adapter, comprising a drainage tube body, a flow rate switch slidably disposed on the outer side of the drainage tube body, a drainage connector installed at one end of the drainage tube body, a connecting reinforcement component installed at the other end of the drainage tube body, a drainage tube limiting component slidably disposed on the outer side of the drainage tube body, the connecting reinforcement component comprising a horn interface, the horn interface being fixedly installed at one end of the drainage tube body, a reinforcing ring and a reinforcing sleeve slidably disposed on the outer side of the horn interface, the reinforcing ring having multiple square openings, matching threads being provided on the outer side of the reinforcing ring and the inner side of the reinforcing sleeve, and a limiting mechanism being installed on the outer side of the horn interface.

[0007] By adopting the above technical solutions, a flow rate switch is used to control the drainage speed of the drainage tube body, keeping it within a suitable range. A drainage connector is used to connect to the pre-installed tube in the patient's body and drain the accumulated fluid. A connection reinforcement component is used to reinforce the connection between the drainage tube and the drainage bag, making the connection more stable and preventing it from being easily torn apart, thus avoiding the drainage bag falling off and causing discomfort to the patient. A drainage tube limiting component is used to limit the height of the drainage tube body, keeping it lower than the connection point with the patient, preventing fluid backflow and thus avoiding infection. A flared interface is used to allow the drainage tube to be snapped into the drainage bag. A reinforcing ring and a reinforcing sleeve are used so that when the two are connected by threads, the reinforcing ring gradually compresses the square hole and slowly tightens, thus applying uniform pressure to the outside of the flared interface, thereby increasing the friction at the connection between the flared interface and the drainage bag, making the connection more secure and extremely difficult to break. A limiting mechanism is provided to limit the reinforcing ring and the reinforcing sleeve.

[0008] The present invention is further configured such that the limiting mechanism includes a first limiting ring and a second limiting ring, the first limiting ring and the second limiting ring being fixedly installed at both ends of the speaker interface.

[0009] By adopting the above technical solution, a limiting effect is applied to the reinforcing ring and the reinforcing sleeve, preventing the reinforcing ring and the reinforcing sleeve from sliding out of the outside of the horn interface.

[0010] The present invention is further configured such that the drainage connector includes a drainage capillary tube and a spiral limiting ring. One end of the drainage tube body is fixedly installed with the drainage capillary tube and the spiral limiting ring. The drainage capillary tube is rotated at the port of the drainage tube body. The spiral limiting ring is installed on the outer side of the end of the drainage tube body. A spiral sleeve is slidably provided on the outer side of the spiral limiting ring. A pressure ring is provided at the end of the spiral sleeve. A screw ring matching the spiral limiting ring is provided on the inner side of the spiral sleeve.

[0011] By adopting the above technical solution, a drainage tube is used to connect with the pre-installed tube in the patient's body. A spiral limiting ring is used to limit the spiral sleeve and prevent it from sliding out of the drainage connector. By using the spiral sleeve, pressure ring, and screw ring, when the spiral sleeve is connected through the thread and spiral limiting ring, the pressure ring will gradually move towards the end of the drainage tube and increase the contact area at the connection between the drainage tube and the patient's pre-embedded tube, gradually pressing the connection together and increasing the friction between the connection points, making the connection more secure.

[0012] The present invention is further configured such that the drainage tube limiting assembly includes a slip ring, the slip ring is slidably installed on the outside of the drainage tube body, a connecting block is fixedly installed on the outside of the slip ring, and an arc-shaped clamp is fixedly installed on the outside of the connecting block.

[0013] By adopting the above technical solution, a slip ring is used to allow the drainage tube limiting component to slide on the outside of the drainage tube body. A connecting block is used to facilitate the installation of the bow-shaped clamp. The bow-shaped clamp is used to limit the drainage tube body. By clamping the bow-shaped clamp on the clothing or under the bed below the drainage connection, the drainage tube body is limited to below the drainage connection, avoiding fluid backflow and causing infection to the patient.

[0014] The present invention is further configured such that a plurality of rubber sealing rings are fixedly installed on the inner side of the speaker interface.

[0015] By adopting the above technical solution, the sealing of the connection between the horn interface and the drainage bag connector is increased, and leakage of drainage liquid is further prevented.

[0016] The present invention is further configured such that both the reinforcing ring and the reinforcing sleeve are made of plastic with high plasticity and good elasticity.

[0017] By adopting the above technical solution, the reinforcing ring and the reinforcing sleeve have good toughness, and they will not be easily damaged when they are connected and tightened.

[0018] The present invention is further configured such that the bow-shaped clamp is made of spring steel with good elasticity and toughness.

[0019] By adopting the above technical solution, the bow-shaped clamp has good resilience, long service life, and will not be easily damaged during use.

[0020] The present invention is further provided that two circular buckles are installed on both sides of the symmetrical clamping of the bow-shaped clamp.

[0021] By adopting the above technical solution, the friction between the bow-shaped clamp and the clamped item is increased during use, thereby enhancing the limiting effect of the bow-shaped clamp.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model, by setting a reinforcing ring and a reinforcing sleeve, allows the reinforcing ring to gradually compress the square hole and slowly tighten when the two are connected by threads, thereby applying pressure evenly to the outside of the horn interface, increasing the friction at the connection between the horn interface and the drainage bag, making the connection between the two more secure and extremely difficult to break, thus avoiding the situation where the drainage bag falls off and causes discomfort to the patient.

[0024] 2. This utility model limits the drainage tube body by setting a drainage tube limiting component. By clamping the bow-shaped clip on the clothing or under the bed below the drainage connection, the height of the drainage tube body is kept lower than the drainage connection with the patient, thus preventing fluid backflow and avoiding infection risks to the patient.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] A type of medical drainage transfer tube, such as Figure 1 - Figure 4As shown, the device includes a drainage tube body 1. A flow rate switch 2 is slidably mounted on the outer side of the drainage tube body 1 to control the drainage speed within a suitable range. A drainage connector 3 is installed at one end of the drainage tube body 1, connecting to a pre-installed tube in the patient's body to drain accumulated fluid. A connection reinforcement component 4 is installed at the other end of the drainage tube body 1 to reinforce the connection between the drainage tube and the drainage bag, making the connection more stable and preventing it from being easily torn apart, thus avoiding leakage. If the drainage bag falls off, causing discomfort to the patient, a drainage tube limiting component 5 is slidably provided on the outer side of the drainage tube body 1. This component limits the height of the drainage tube body 1 below the connection point with the patient, preventing fluid backflow and thus avoiding infection. The connection reinforcement component 4 includes a flared interface 41, which is fixedly installed at one end of the drainage tube body 1. The flared interface 41 allows the drainage tube to be engaged with the drainage bag. A reinforcing ring 42 and a reinforcing sleeve 43 are slidably installed on the outer side of the flared interface 41. The reinforcing ring 42 has multiple square openings 44. The reinforcing ring 42 and the reinforcing sleeve 43 are both provided with matching threads. By using the reinforcing ring 42 and the reinforcing sleeve 43, when they are connected by threads, the reinforcing ring 42 gradually compresses the square hole 44 and slowly tightens, thereby applying uniform pressure to the outside of the horn interface 41. This increases the friction at the connection between the horn interface 41 and the drainage bag, making the connection more secure and extremely difficult to break. Both the reinforcing ring 42 and the reinforcing sleeve 43 are made of highly malleable and elastic plastic, giving them good toughness. When the reinforcing ring 42 and the reinforcing sleeve 43 are tightened, they will not easily break. To prevent damage, multiple rubber sealing rings 45 are fixedly installed on the inner side of the horn interface 41, thereby increasing the sealing of the connection between the horn interface 41 and the drainage bag connector and further preventing leakage of drainage liquid. A limiting mechanism is also installed on the outer side of the horn interface 41. The limiting mechanism includes a first limiting ring 46 and a second limiting ring 47. The first limiting ring 46 and the second limiting ring 47 are respectively fixedly installed at both ends of the horn interface 41. By providing the first limiting ring 46 and the second limiting ring 47, a limiting effect is applied to the reinforcing ring 42 and the reinforcing sleeve 43, preventing the reinforcing ring 42 and the reinforcing sleeve 43 from sliding off the outer side of the horn interface 41.

[0033] Please see Figure 1 and Figure 3The drainage connector 3 includes a drainage tube 31, a spiral limiting ring 32, and a spiral sleeve 33. The drainage tube 31 and the spiral limiting ring 32 are fixedly installed at one end of the drainage tube body 1. The drainage tube 31 is mounted at the port of the drainage tube body 1. The spiral limiting ring 32 is installed on the outer side of the end of the drainage tube body 1. The spiral sleeve 33 is slidably provided on the outer side of the spiral limiting ring 32. A pressure ring 34 is provided at the end of the spiral sleeve 33. A screw ring 35 matching the spiral limiting ring 32 is provided on the inner side of the spiral sleeve 33. The drainage tube 31... This allows it to connect with the pre-installed tubes in the patient's body. The spiral limiting ring 32 provides a limiting effect on the spiral sleeve 33, preventing it from sliding out of the drainage connector 3. With the spiral sleeve 33, pressure ring 34, and screw ring 35, when the spiral sleeve 33 is connected to the spiral limiting ring 32 through the thread, the pressure ring 34 will gradually move towards the end of the drainage tube 31, increasing the contact area at the connection between the drainage tube 31 and the patient's pre-embedded tube, gradually pressing the connection together, thereby increasing the friction between the connection points and making the connection more secure.

[0034] Please see Figure 1 and Figure 4 The drainage tube limiting assembly 5 includes a slip ring 51, which is slidably mounted on the outside of the drainage tube body 1. A connecting block 52 is fixedly mounted on the outside of the slip ring 51, and an arc-shaped clamp 53 is fixedly mounted on the outside of the connecting block 52. The arc-shaped clamp 53 is made of spring steel with good elasticity and toughness, which makes the arc-shaped clamp 53 have good resilience during use, long service life and not easily damaged. Two circular buckles 54 are installed on both sides of the symmetrical clamping of the arc-shaped clamp 53. The drainage tube is limited by the slip ring 51. The positioning component 5 can slide on the outside of the drainage tube body 1. The connecting block 52 facilitates the installation of the bow-shaped clamp 53. The bow-shaped clamp 53 limits the drainage tube body 1. By clamping the bow-shaped clamp 53 on the clothing or under the bed below the drainage connection, the drainage tube body 1 is limited to below the drainage connection, avoiding fluid backflow and infection hazards to the patient. The circular buckle 54 increases the friction between the bow-shaped clamp 53 and the clamped object during use, thus increasing the limiting effect of the bow-shaped clamp 53.

[0035] The working principle of this utility model is as follows: When using the drainage adapter, first connect the flared interface 41 to the drainage bag connector, then slide the reinforcing ring 42 to the end of the flared interface 41, rotate the reinforcing sleeve 43, and rotate it to connect with the reinforcing ring 42 through the thread, so that the reinforcing ring 42 will gradually compress the square hole 44 and slowly tighten it, thereby reinforcing the connection between the drainage bag and the flared interface 41 and preventing the drainage bag connection from falling off. Then, install the drainage tube body 1 below the patient's drainage interface through the bow-shaped clamp 53 to avoid liquid backflow. Finally, connect the drainage tube 31 to the pre-embedded tube in the patient's body. Next, rotate the spiral sleeve 33, which connects to the spiral limiting ring 32 via threads, so that the pressure ring 34 presses tightly against the drainage connection between the drainage tube 31 and the patient's pre-embedded tube, thus strengthening the connection between the two. Adjust the flow rate switch 2 so that the fluid in the patient's body is drained at a suitable speed. After the drainage is completed, rotate the spiral sleeve 33 to release the connection with the spiral limiting ring 32, thereby releasing the reinforcement effect. Pull out the drainage tube 31 and seal the pre-embedded tube in the patient's body to avoid infection. Then rotate the reinforcing sleeve 43 to release the connection between the reinforcing sleeve 43 and the reinforcing ring 42. Pull out the drainage bag and seal it. The drainage work is now complete.
