Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and specifically relates to a medical catheter connection device. Background Technology

[0002] Medical catheters play a crucial role in modern medicine. Taking medical drainage catheters as an example, they are widely used in surgical procedures, postoperative recovery, intensive care, and the treatment of various diseases, such as urinary system diseases, pleural effusion drainage, and biliary drainage. Medical drainage catheters effectively remove fluid, secretions, or gas from the body, helping to maintain internal homeostasis, promote wound healing, reduce organ stress, prevent the spread of infection, and create favorable conditions for patient recovery. Furthermore, in some applications, medical catheters and catheter connectors need to be bonded together using UV adhesive.

[0003] The traditional connection method involves first manually applying UV adhesive to the connection surface of the medical catheter, a process highly dependent on the operator's experience and skills. Then, the medical catheter and catheter connector are manually joined, and finally placed in specialized curing equipment for UV light curing. In this approach, because the entire adhesive application and connection process is largely manual, each step requires time, including adhesive preparation, application, catheter-connector connection, and curing equipment operation, resulting in low efficiency. Furthermore, manual adhesive application is difficult to perform quickly and continuously. In large-scale production or emergency medical supply manufacturing, this inefficient connection method severely restricts production progress and the timeliness of medical services. In addition, it is difficult to precisely control the thickness and uniformity of the adhesive during manual application. Inconsistent operator speed, pressure, or technique can easily lead to adhesive accumulation, insufficient adhesive, or inconsistent thickness on the connection surface. Even with automated adhesive application equipment for catheters, the instability of manual operation during catheter-connection can lead to misalignment, such as misalignment, tilting, or insufficient insertion depth. These issues further affect adhesive distribution on the connection surface, preventing complete coverage and creating gaps or weak areas. Ultimately, poor connection quality directly impacts the bonding strength and sealing of the catheter and connector, potentially causing serious problems like leakage and detachment during use. This not only reduces medical efficacy but can also lead to infections and other medical accidents, threatening the patient's life and health.

[0004] With the continuous advancement of medical technology and the increasing demand for medical services, higher requirements are being placed on the quality, reliability, and production efficiency of medical catheters. There is a desire to obtain medical catheter products that are securely connected, have excellent sealing properties, and are produced efficiently to meet the growing needs of surgeries and treatments. Therefore, it is necessary to improve the connection methods of existing medical catheters and catheter connectors. Utility Model Content

The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0035] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of the present invention include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0036] In the embodiments of this utility model, the terms "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of this utility model should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner. It should be noted that, based on common knowledge in the art, the following preferred embodiments can be arbitrarily combined to obtain various preferred embodiments of this utility model.

[0037] like Figures 1 to 8 As shown, this embodiment provides a medical catheter connection device for connecting a medical catheter 10 and a catheter connector 20, for example, for connecting a medical drainage catheter to the catheter connector 20. The catheter connector 20 described herein is any connector known in the art, and the medical catheter 10 is preferably any rigid catheter. More specifically, the medical catheter connection device includes: a rotating mechanism 1, a glue spraying component 2, a glue spreading component 3, and a docking mechanism 4.

[0038] Figures 1 to 4 The docking mechanism 4 is not shown. The rotating mechanism 1 is configured to rotate around its own central axis, and the rotation speed can be adjusted and set according to actual needs. The rotation speed of the rotating mechanism 1 corresponds to the glue-spreading speed of the glue-spreading component 3, allowing for both fast and slow glue-spreading. The rotating mechanism 1 also has an installation channel 11 running along its own central axis, as detailed in [link to details]. Figures 5 to 8 The installation channel 11 allows the medical catheter 10 or catheter connector 20 to pass through, facilitating the mating installation of the medical catheter 10 and catheter connector 20. The installation channel 11 is typically a circular channel.

[0039] The adhesive spraying component 2 is used to spray UV adhesive 30. The adhesive spraying component 2 is generally arranged vertically and sprays adhesive towards the central axis of the rotating mechanism 1. Specifically, the adhesive spraying component 2 is located in front of the rotating mechanism 1, independently of the rotating mechanism 1 and the docking mechanism 4. The adhesive spraying component 2 is configured to be close to or far from the rotating mechanism 1, meaning that the spraying distance of the adhesive spraying component 2 is adjustable. Since different UV adhesives 30 have different viscosities, the spraying distance can also be different; for example, when the UV adhesive 30 has a high viscosity, the spraying distance can be reduced, and vice versa. The adhesive spraying component 2 can adopt various nozzle structures known in the art. Furthermore, one or more specifications of adhesive spraying components 2 can be provided. With multiple specifications, it is convenient to change the corresponding adhesive spraying component 2 according to the adhesive application needs, making it more convenient and flexible to use. It should also be noted that the adhesive spraying component 2 needs to be connected to an adhesive spraying pipeline so that the UV adhesive 30 is delivered to the adhesive spraying component 2 through the adhesive spraying pipeline.

[0040] The coating applicator 3 is directly mounted on the rotating mechanism 1, specifically at the front end of the mounting channel 11, so that the coating applicator 3 can rotate with the rotating mechanism 1, thereby applying the UV adhesive 30 sprayed onto the first target object (medical catheter 10 in the figure), so that the UV adhesive 30 on the first target object is evenly distributed on the connecting surface, ensuring coating thickness and uniformity.

[0041] When the medical catheter connection device of this embodiment is in operation, such as Figure 3 As shown, UV adhesive 30 can be sprayed first using spray nozzle 2. After stopping the spraying, as shown... Figure 4 As shown, the rotating mechanism 1 is activated to rotate (refer to arrow A1), which in turn drives the spreading component 3 to rotate circumferentially, spreading the UV adhesive 30 evenly. In other cases, the spraying component 2 can spray adhesive continuously while the rotating mechanism 1 rotates, driving the spreading component 3 to perform the spreading operation; that is, spraying and spreading are performed simultaneously. During adhesive application, the first target object can either rotate or remain stationary. During spreading, typically the first target object remains stationary, allowing the rotating mechanism 1 to drive the spreading component 3 to rotate around the first target object.

[0042] Unlike traditional adhesive coating methods, this embodiment utilizes the rotating application of the coating element 30 to ensure that the UV adhesive 30 adheres as evenly as possible to the bonding surface of the first target object. It should be noted that the rotating mechanism 1 can be controlled to drive the coating element 3 to apply the adhesive to one side or a specific area (i.e., localized angle application) of the first target object, achieving uniform application at a specific circumferential angle. Alternatively, the rotating mechanism 1 can be controlled to drive the coating element 3 to perform 360° all-around application, making the coating process convenient and flexible.

[0043] Furthermore, Figures 5 to 8The diagram illustrates a scenario where the docking mechanism 4 is used after the adhesive has been applied. The docking mechanism 4 is located in front of and behind the rotating mechanism 1, and is set independently of the rotating mechanism 1. The docking mechanism 4 is configured to drive the catheter connector 20 and the medical catheter 10 to dock via the mounting channel 11 after the UV adhesive 30 has been applied to the first target object (such as a medical catheter 10).

[0044] In one embodiment, the catheter connector 20 is limited and held stationary by the second docking mechanism 420, and the medical catheter 10 is driven by the first docking mechanism 410 through the installation channel 11 to dock with the catheter connector 20 behind it.

[0045] In another configuration, the medical catheter 10 is held in place by the first docking mechanism 410, and the catheter connector 20 is driven by the second docking mechanism 420 through the installation channel 11 to dock with the medical catheter 10 in front.

[0046] In some other ways, the medical catheter 10 and the catheter connector 20 are simultaneously driven to move in opposite directions by the docking mechanism 4 and docked via the installation channel 11.

[0047] Regardless of the docking method, it can achieve highly efficient docking and installation, with good stability, small operational errors, and high docking quality, overcoming the deviation problems that exist in the current manual docking.

[0048] Thus, it can be understood that when the first target object is the medical catheter 10 and the second target object is the catheter connector 20, the medical catheter 10 is directly coated with adhesive, and during docking and installation, the medical catheter 10 is embedded in the catheter connector 20; conversely, when the first target object is replaced by the catheter connector 20 and the second target object is replaced by the medical catheter 10, the catheter connector 20 is directly coated with adhesive, the adhesive application method is the same as in the aforementioned embodiment, and during docking and installation, the catheter connector 20 is embedded in the medical catheter 10.

[0049] Therefore, the medical catheter connection device provided in this embodiment can meet various needs, such as the medical catheter 10 being built into the catheter connector 20 or the catheter connector 20 being built into the medical catheter 10. It can also enable the installation of various catheter connectors 20 onto the medical catheter 10, and allows for selection of opposite-facing installation of the medical catheter 10 or catheter connector 20, or unilateral moving installation, resulting in a more stable installation process. Furthermore, during operation, the medical catheter connection device can be adjusted according to requirements such as catheter diameter, adhesive application amount, and application area to meet the needs of various situations.

[0050] It should also be understood that after the medical catheter 10 and catheter connector 20 are connected and installed, they need to be UV cured in a certain way. UV curing can be performed in specialized curing equipment, or a UV curing lamp 5 can be used for direct curing after connection and installation, resulting in higher efficiency and greater convenience.

[0051] like Figure 7 and Figure 8 As shown, the medical catheter connection device may further include an ultraviolet curing lamp 5, which is selectively positioned in front of the rotating mechanism 1. When curing is not required, the ultraviolet curing lamp 5 is positioned at any other location. When curing is required, the ultraviolet curing lamp 5 is moved to the front of the rotating mechanism 1. After the medical catheter 10 and the catheter connector 20 are connected and installed, the ultraviolet light from the ultraviolet curing lamp 5 is used to irradiate the connection point between the medical catheter 10 and the catheter connector 20, thereby curing the UV adhesive 30.

[0052] Figure 8 The image shows that before UV curing, the sprayed adhesive part 2 is driven away from the rotating mechanism 1 in the direction indicated by arrow A3.

[0053] Figure 8 It is also shown that the light 51 emitted by the UV curing lamp 5 can uniformly illuminate all contact surfaces of the medical catheter 10 and the catheter connector 20. Preferably, the integral structure formed by the mating of the medical catheter 10 and the catheter connector 20 remains stationary, at which time the UV curing lamp 5 can be driven to rotate circumferentially around the integral structure of the medical catheter 10 and the catheter connector 20, thereby achieving UV curing of the UV adhesive 30. Of course, the actual implementation is not limited to this.

[0054] Return to reference Figures 1 to 2 A clamping block 12 is provided on the outer front end of the mounting channel 11, and the clamping block 12 clamps the applicator 3. The applicator 3 can be made into various shapes, and there is no limitation thereto. Here, the applicator 3 is fixed by clamping, which facilitates the adjustment of the distance of the applicator 3 relative to the central axis of the rotating mechanism 1, so that the distance of the applicator 3 can be adjusted according to the amount of glue applied, the viscosity of the glue, and the application area. Preferably, the applicator 3 is arranged radially along the mounting channel 11, which can better apply the UV glue 30.

[0055] One or more of the spreading components 3 are used. Each clamping block 12 is correspondingly arranged to one spreading component 3. As shown in the figure, there are multiple clamping blocks 12 arranged circumferentially around the central axis of the rotating mechanism 1, with each clamping block 12 holding one spreading component 3. The use of multiple spreading components 3 results in higher coating efficiency and better spreading effect.

[0056] The adhesive coating component 3 is mainly made of soft materials, such as sponge, rubber, or brush, or other soft materials with similar or identical properties.

[0057] Furthermore, the adhesive spraying component 2 is mounted on the moving mechanism 6 and held and fixed by the clamp 7. Specifically, the clamp 7 is mounted on the moving mechanism 6, and the moving mechanism 6 is used to drive the clamp 7 to move the adhesive spraying component 2 away from or towards the rotating mechanism 1. In practice, the moving mechanism 6 can use various methods to drive the clamp 7 to move. As described in the figure, the moving mechanism 6 includes a slide rail 61 and a slider 62 disposed on the slide rail 61; the slide rail 61 is installed vertically and is independent of the rotating mechanism 1; the slider 62 can move along the slide rail 61, thereby driving the adhesive spraying component 2 to move vertically; the clamp 7 is mounted on the slider 62 and clamps the adhesive spraying component 2. This structure is simple and easy to use and operate.

[0058] As one way of using it, the spraying part 2 can be replaced according to the required amount of glue. Specifically, the spraying part 2 can be reconfigured by the clamp 7, and different sizes of spraying parts 2 can be replaced. The spraying distance of the spraying part 2 can also be adjusted according to the amount of glue applied.

[0059] Figures 5 to 8 The diagram also shows a feeding turntable 8 in a medical catheter connection device. The feeding turntable 8 is rotatably positioned in front of the rotating mechanism 1. The feeding turntable 8 has multiple installation stations along its circumference, each capable of holding a first target object. Each first target object at each installation station is moved to an adhesive application station in front of the rotating mechanism 1 for adhesive application as the feeding turntable 8 rotates. The adhesive application station is located in front of and coaxially aligned with the installation channel 11. This design allows for automatic feeding and rapid material replacement, significantly improving efficiency.

[0060] Generally, medical catheters 10 are optimally used as the primary target. As shown in the figure, the central axis of the feeding turntable 8 is parallel to the central axis of the rotating mechanism 1, and all installation stations are located on the same circumference, which passes exactly through the central axis of the rotating mechanism 1. Furthermore, each medical catheter 10 is not limited to those depicted in the figure; one end is fixed to the installation station, and the remaining portion hangs naturally downwards.

[0061] Figures 5 to 8 A docking mechanism 4 is also shown. The docking mechanism 4 may include a first docking mechanism 410 and a second docking mechanism 420. The first docking mechanism 410 is located in front of the rotating mechanism 1; the second docking mechanism 420 is located behind the rotating mechanism 1; the first docking mechanism 410 can pre-tighten the first target object in the rear direction of the rotating mechanism 1 (refer to arrow A2) to restrict the position of the first target object; the second docking mechanism 420 can drive the second target object (the catheter connector 20 described in the figure) through the installation channel 11 and dock with the first target object (the medical catheter 10 described in the figure) in the front direction of the rotating mechanism 1 (refer to arrow A5).

[0062] Optionally, the first docking mechanism 410 includes a drive screw 411 and a preload block 412 disposed on the drive screw 411. The drive screw 411 can be driven to rotate, thereby causing the preload block 412 to slide along the drive screw 411, thereby preloading the first target object.

[0063] Optionally, the second docking mechanism 420 includes a push rod 421 and a guide rail 422. The push rod 421 is limited in the guide rail 422. The push rod 421 can be driven to drive the second target object through the installation channel 11 to dock and install with the first target object.

[0064] It should be understood that although the preceding embodiments describe the docking mechanism 4 in conjunction with the structural arrangement shown in the accompanying drawings, the first docking mechanism 410 and the second docking mechanism 420 can both be implemented in various ways. Therefore, in addition to the implementation methods listed in the accompanying drawings, those skilled in the art can find other alternative ways to achieve the functions / effects described in this application based on the description in this application, and not just the solutions disclosed in this embodiment.

[0065] Finally, it should be added that although the innovation of this application originates from the field of medical drainage catheter technology, those skilled in the art will understand that this application can also be applied to the connection of other medical catheters and connectors, thereby enabling the bonding technology to play a more active role in clinical applications.

[0066] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of this utility model, which do not affect the substantive content of this utility model. Unless otherwise specified, the embodiments and features of the embodiments of this utility model can be arbitrarily combined with each other.
