Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an improved Robert clip. Background Technology

[0002] Robert's clip, a type of waterproofing clip widely used in the medical device field, has an overall structure as follows: Figure 1 As shown, the existing Robert clamp typically has an integrated semi-open clamp body 1P, and hollow holes 2P are provided at both ends of the integrated semi-open clamp body 1P for the hose to pass through. When the locking free end 11P of the integrated semi-open clamp body 1P is pressed to lock it into the unlocking free end 12P of the integrated semi-open clamp body 1P, the integrated semi-open clamp body 1P will form a closed structure, and the hose will be clamped by the upper pressing protrusion 3P and the lower pressing protrusion 4P to achieve the function of stopping the flow.

[0003] However, the existing Robert clamps have closed perforations (2P), requiring the hose end to pass through both perforations (2P) sequentially for installation. This limits the use of existing Robert clamps to pre-installation at the required location on the pipeline, making it impossible to install and use them immediately or replace / maintain them during normal pipeline operation. Furthermore, for pipelines without pre-installed Robert clamps, adding them temporarily is problematic because the perforations (2P) in the existing clamps cannot accommodate most connectors. Therefore, the pipeline connectors must be removed before installation, which not only affects the sterile environment within the pipeline but is also extremely cumbersome and inconvenient.

[0004] To address this issue, existing solutions typically involve using a flat-bottomed clamp during installation. However, flat-bottomed clamps are significantly heavier than Robert clamps. They require two hands to operate and clamp the tubing, and when not clamping, they cannot remain on the tubing for re-clamping. Consequently, the clamps must be stored away for re-installation the next time the tubing is needed. This inconvenience severely hinders the efficiency of medical staff. Summary of the Invention

[0005] One advantage of this invention is that it provides an improved Robert clip that, while retaining the advantages of existing Robert clips, solves the problem that existing Robert clips cannot be installed and used immediately or replaced at any time.

[0006] Another advantage of this invention is that it provides an improved Robert clamp that combines the advantages of both existing Robert clamps and slotted pipe clamps, making installation and use more flexible and convenient.

[0007] Another advantage of the present invention is that it provides an improved Robert clamp, wherein, in one embodiment of the present invention, the improved Robert clamp can be disassembled and replaced at any time during the use of the flexible tube, and can remain on the flexible tube when clamping is not required for re-clamping, which helps to improve the work efficiency of medical staff.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on 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.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Considering that existing Robert clamps cannot be used immediately after installation, and that single-piece clamps cannot remain on the tubing for re-clamping when not clamping, both methods are extremely inconvenient to operate, severely restricting the work efficiency of medical staff. To solve the above problems, this application proposes an improved Robert clamp that retains the advantages of existing Robert clamps while solving the problem that existing Robert clamps cannot be used immediately after installation or replaced at any time.

[0040] Specifically, see the attached document. Figures 2 to 5As shown, one embodiment of the present invention provides an improved Robert clamp 1 for releasably clamping a flexible tube 2. It is worth noting that the flexible tube mentioned in this application refers to a deformable tube, such as an infusion tube or drainage tube. Thus, when the improved Robert clamp 1 clamps the flexible tube 2, the channel within the flexible tube 2 is closed to prevent flow; when the improved Robert clamp 1 releases the flexible tube 2, the channel within the flexible tube 2 is opened, and the improved Robert clamp 1 remains on the flexible tube 2 for re-clamping.

[0041] More specifically, such as Figure 2 and Figure 3 As shown, the improved Robert clip 1 may include a clip body 10, a locking member 20, and a limiting member 30. The clip body 10 includes a first clamping portion 11, a second clamping portion 12 spaced apart from the first clamping portion 11, and a connecting portion 13 extending integrally from the rear end of the first clamping portion 11 to the rear end of the second clamping portion 12. The locking member 20 includes a pressing portion 21 integrally connected to the front end of the first clamping portion 11 and a locking portion 22 integrally connected to the front end of the second clamping portion 12. The locking portion 22 extends bently from the front end of the second clamping portion 12 toward the pressing portion 21 to releasably lock the pressing portion 21. The limiting member 30 is disposed on the clamping body 10 and / or the engaging member 20, and the limiting member 30 has a notch 300 for limiting the flexible tube 2 inserted into the notch 300, so that the improved Robert clamp 1 remains on the flexible tube 2 after the flexible tube 2 is released (i.e., the flexible tube 2 is not clamped to transfer fluid) so as to clamp it again, thus preventing the flexible tube 2 from displacing and coming out of the improved Robert clamp 1 during use. It is understood that the front and back mentioned in this application are relative, only to distinguish the position of the connecting part 13 and the engaging member 20 relative to the first clamping part 11 and the second clamping part 12; for example, when the connecting part 13 is located behind the first clamping part 11 and the second clamping part 12, the engaging member 20 is located in front of the first clamping part 11 and the second clamping part 12.

[0042] For example, such as Figure 3 and Figure 4 As shown, the limiting member 30 may include a first limiting part 31 extending forward at an incline from the connecting part 13 to form a first notch 310 between the first limiting part 31 and the connecting part 13, for limiting the flexible tube 2 inserted into the first notch 310 from the rear of the clamp body 10, so that the improved Robert clamp 1 remains on the flexible tube 2 after releasing the flexible tube 2 (i.e. the flexible tube 2 is not clamped to transfer fluid) so as to clamp it again, and prevents the flexible tube 2 from displacing and coming out of the improved Robert clamp 1 during use.

[0043] It is worth noting that although the improved Robert clip 1 of this application improves the installation structure of the existing Robert clip, it retains the basic clamping structure of the existing Robert clip, which is in line with the user's usage habits. In detail, when the user uses the improved Robert clip 1 to stop the flow of the flexible tube 2, he only needs to press the pressing part 21 relative to the locking part 22, and the locking part 22 can lock the pressing part 21 to achieve locking; at the same time, the first clamping part 11 approaches the second clamping part 12 to clamp the flexible tube 2 inserted into the first notch 310, so that the channel inside the flexible tube 2 is closed, and the flow-stopping operation can be achieved without changing the user's operating habits. Similarly, when a user wants to release the flow-stopping effect of the improved Robert clamp 1 on the flexible tube 2, they only need to pry the locking part 22 away from the pressing part 21 to release the pressing part 21, which will unlock the tube. At this time, the first clamping part 11 moves away from the second clamping part 12 to release the flexible tube 2 that is stuck in the first notch 310, so that the channel inside the flexible tube 2 is opened. At the same time, the flexible tube 2 is still stuck in the first notch 310, so that the improved Robert clamp 1 remains on the flexible tube 2 for re-clamping, without having to be retracted like a straight pipe clamp.

[0044] Furthermore, the improved Robert clip 1 of this application can be easily attached to or removed from the flexible tube 2 in use, enabling it to be installed and used immediately and replaced at any time. This makes the use of the Robert clip more flexible and convenient, helping to improve the work efficiency of medical staff. Specifically, when the improved Robert clip 1 needs to be attached to the flexible tube 2, simply insert the body of the flexible tube 2 into the first notch hole 310 from the notch, and then insert the body of the flexible tube 2 through the gap or opening between the pressing part 21 and the snap-fit ​​part 22, so that the flexible tube 2 is positioned between the first clamping part 11 and the second clamping part 12. This completes the installation of the improved Robert clip 1. The fluid transfer operation within the flexible tube 2 does not need to be stopped during the entire process, which is something that existing Robert clips cannot achieve. It is understandable that, during the installation of the improved Robert clip 1, the flexible tube 2 can be inserted through the gap between the pressing part 21 and the snap-fit ​​part 22 first, and then the flexible tube 2 can be snapped into the first notch 310. This application will not elaborate further on this.

[0045] Similarly, when it is necessary to remove the improved Robert clip 1 from the flexible tube 2, it is only necessary to move the tube body of the flexible tube 2 out of the first notch hole 310 from the notch and remove the tube body of the flexible tube 2 from the gap or opening between the pressing part 21 and the snap-fit ​​part 22 to complete the removal of the improved Robert clip 1. The fluid transfer operation in the flexible tube 2 does not need to be stopped during the entire process.

[0046] According to the above embodiments of this application, as Figure 3 and Figure 5 As shown, the limiting member 30 of the improved Robert clip 1 further includes a second limiting portion 32 that extends rearwardly from the snap-fit ​​portion 22 to form a second notch 320 between the second limiting portion 32 and the snap-fit ​​portion 22, for limiting the flexible tube 2 that is snapped into the second notch 320, so as to provide double restriction to the flexible tube 2 and prevent the improved Robert clip 1 from disengaging from the flexible tube 2 when it is not clamped.

[0047] Preferably, such as Figure 2 and Figure 3 As shown, the first limiting part 31 and the second limiting part 32 are located on the left and right sides of the clamp body 10, respectively. This allows the flexible tube 2 to be stably restrained between the first clamping part 11 and the second clamping part 12 after it is simultaneously inserted into the first notch 310 and the second notch 320. This facilitates the reliable clamping of the flexible tube 2 by the first clamping part 11 and the second clamping part 12 when the locking part 22 engages with the pressing part 21, thereby better achieving the flow-stopping function. It is understood that the first limiting part 31 and the second limiting part 32 of this application are arranged in different directions on the clamp body 10, and their force directions on the pipeline are also different. This makes it easier to insert the flexible tube 2 during installation and to limit the flexible tube 2 within the improved Robert clamp 1, preventing the flexible tube 2 from shifting and becoming unable to be clamped.

[0048] For example, such as Figure 2 and Figure 4 As shown, the first clamping portion 11 of the clamping body 10 may include a first clamping arm 111 extending integrally forward from the first end 131 of the connecting portion 13 to the pressing portion 21, and a first clamping block 112 protruding from the first clamping arm 111 toward the second clamping portion 12. Thus, when the body of the flexible tube 2 is simultaneously inserted into the first notch 310 and the second notch 320, the body of the flexible tube 2 is positioned between the first clamping block 112 and the second clamping portion 12, facilitating the flattening of the body of the flexible tube 2 to achieve a flow-stopping effect.

[0049] Optionally, such as Figure 2 and Figure 4 As shown, the second clamping part 12 may include a second clamping arm 121 that extends integrally forward from the second end 132 of the connecting part 13 to the snap-fit ​​part 22, and a second clamping block 122 that protrudes from the second clamping arm 121 toward the first clamping block 112. Thus, when the body of the flexible tube 2 is simultaneously inserted into the first notch 310 and the second notch 320, the body of the flexible tube 2 is positioned between the first clamping block 112 and the second clamping block 122, facilitating better flattening of the body of the flexible tube 2 to achieve a flow-stopping effect.

[0050] It is worth noting that, since the first limiting part 31 and the second limiting part 32 are located on the left and right sides of the clamping body 10 respectively, the flexible tube 2, after being simultaneously inserted into the first notch 310 and the second notch 320, extends obliquely from back to front. Therefore, the first clamping block 112 of this application extends obliquely from left to right on the first clamping arm 111, and the extension direction of the first clamping block 112 is perpendicular to the axial direction of the flexible tube 2, which facilitates clamping the flexible tube 2 to completely block the flow section inside the flexible tube 2, thus achieving a better flow-stopping effect. It is understandable that if the extension direction of the first clamping block 112 is not perpendicular to the axial direction of the flexible tube 2, but is oblique, then a longer clamping block and a greater clamping force are required to completely block the flow section inside the flexible tube 2, otherwise it will be unable to resist the pressure inside the flexible tube 2.

[0051] Similarly, such as Figure 2 and Figure 3 As shown, the second clamping block 122 extends obliquely from left to right on the second clamping arm 121, and the extension direction of the second clamping block 122 is perpendicular to the axial direction of the flexible tube 2, so that the flexible tube 2 can be completely clamped using a shorter second clamping block 122 and a smaller clamping force.

[0052] Preferably, such as Figure 2 and Figure 3 As shown, the head of the first clamping block 112 is aligned with the head of the second clamping block 122, so that the first clamping block 112 and the second clamping block 122 can better clamp the body of the flexible tube 2, which facilitates the desired flow-stopping effect.

[0053] Optionally, such as Figure 4 and Figure 5 As shown, the first clamping block 112 integrally protrudes from the inner surface of the first clamping arm 111 to form a hollow convex strip; similarly, the second clamping block 122 integrally protrudes from the inner surface of the second clamping arm 121 to form another hollow convex strip. In this way, the first clamping block 112 and the second clamping block 122 can clamp the flexible tube 2 to stop the flow while reducing their own weight, which helps to reduce the material cost and overall weight of the improved Robert clamp 1.

[0054] According to the above embodiments of this application, as Figure 2 and Figure 4As shown, the first limiting portion 31 of the limiting member 30 may include a rear limiting rod 311 extending curvedly from the first end 131 of the connecting portion 13 toward the second clamping arm 121, forming the first notch 310 between the rear limiting rod 311 and the connecting portion 13, and forming a notch in the first notch 310 between the rear limiting rod 311 and the second clamping arm 121. Thus, when the body of the flexible tube 2 is inserted into the first notch 310, the body of the flexible tube 2, supported by the second clamping block 122, will move away from the second clamping arm 121, causing the body of the flexible tube 2 to move away from the notch in the first notch 310, preventing the flexible tube 2 from falling out of the first notch 310 during use, improving the limiting effect of the first limiting portion 31, and enhancing the installation stability of the improved Robert clamp 1. It is understood that in other examples of this application, the first limiting part 31 may also be implemented as a rear limiting rod that extends curvedly from the second end 132 of the connecting part 13 toward the first clamping arm 111, so as to form a notch in the first notch hole 310 between the rear limiting rod 311 and the first clamping arm 111, which can still achieve a good limiting effect. This application will not elaborate further on this.

[0055] Similarly, such as Figure 2 and Figure 5 As shown, the second limiting portion 32 of the limiting member 30 may include a front limiting rod 321 that extends curvedly from the snap-fit ​​portion 22 toward the second clamping portion 12 to form the second notch 320 between the front limiting rod 321 and the snap-fit ​​portion 22, and to form a notch in the second notch 320 between the front limiting rod 321 and the second clamping portion 12 to prevent the flexible tube 2 from falling out of the second notch 320 during use.

[0056] Optionally, such as Figure 2 and Figure 5 As shown, the second clamping part 12 may further include a mating rod 123 extending integrally from the front end of the second clamping arm 121 toward the front limiting rod 321, so as to form a notch in the second notch hole 320 between the front limiting rod 321 and the mating rod 123, so that there is a certain distance between the notch in the second notch hole 320 and the second clamping arm 121, so that the flexible tube 2 after being inserted into the first notch hole 310 only needs to be slightly bent to be inserted into the second notch hole 320, in order to prevent the notch in the first notch hole 310 and the notch in the second notch hole 320 from being adjacent to the second clamping arm 121, which would increase the difficulty of inserting the flexible tube 2.

[0057] Optionally, such as Figure 5As shown, the extension length of the mating rod 123 is less than the extension length of the front limiting rod 321, so that the notch of the second notch 320 is adjacent to the second clamping arm 121, which helps to reduce the risk of the flexible tube 2 falling out of the second notch 320 during use.

[0058] Optionally, the shapes of the rear limiting rod 311 and the front limiting rod 321 are adapted to the outer shape of the flexible tube 2, so that the side of the rear limiting rod 311 and the front limiting rod 321 facing the flexible tube 2 is in contact with the surface of the flexible tube 2. This not only better limits the tube body of the flexible tube 2, but also prevents wear on the surface of the flexible tube 2. For example, the rear limiting rod 311 and the front limiting rod 321 are both implemented as arc-shaped rods. It is understood that during the use of the improved Robert clamp 1, the flexible tube 2 has pressure due to the presence of fluid, which causes friction to occur at the contact points between the surface of the flexible tube 2 and the rear limiting rod 311 and the front limiting rod 321. The arc-shaped rods of this application can fit the surface of the flexible tube 2, which helps to reduce friction, improve the service life of both, and reduce safety hazards.

[0059] Optionally, both the rear limiting rod 311 and the front limiting rod 321 are rounded and smoothed, which not only prevents damage to the flexible tube 2 during installation, but also further reduces wear during use.

[0060] It is worth noting that the improved Robert clip 1 of this application still has a one-piece molded structure, that is, the improved Robert clip 1 is integrally molded from a flexible material such as plastic or polymer material; in this way, the limiting member 30 can be inserted into flexible tubes of different outer diameters due to the flexibility of its own material, which is convenient to meet the assembly of different pipelines and expands the application range of the improved Robert clip 1.

[0061] In addition, on the one hand, the improved Robert clamp 1 of this application can effectively restrict the range of motion of the flexible tube 2 after installation, and will not fall off; on the other hand, the improved Robert clamp 1 of this application retains the basic clamping structure of the existing Robert clamp, and can be used immediately after installation by simply setting a notch hole.

[0062] In particular, existing Robert clamps have a central perforation in the connecting part of the clamp body, resulting in a smaller width on both sides of the connecting part and a lower overall strength of the clamp body, making it difficult to clamp flexible tubes with high internal pressure. However, the improved Robert clamp 1 of this application not only does not reduce the overall strength and clamping effect, but also enhances the overall strength and clamping effect. This is because the notch 300 in the improved Robert clamp 1 is formed by the limiting member 30 and the connecting part 13, so that there is no need to open a perforation in the connecting part 13, which increases the width of the connecting part 13, resulting in a greater overall strength of the clamp body 10 and improved clamping effect. This is extremely important for flexible tubes with high internal pressure or high material hardness. At the same time, the increased strength of the clamp 10 at the connection 13 not only helps to unlock the locking part 22 and the pressing part 21, but also ensures that after the locking part 22 releases the pressing part 21, the first clamping part 11 and the second clamping part 12 move away from each other to better release the flexible tube 2, making it easier for the flexible tube 2 to recover and open the flow channel inside the flexible tube 2.

[0063] Optionally, such as Figure 2 and Figure 3 As shown, the connecting portion 13 extends backward from the rear end of the first clamping portion 11 to the rear end of the second clamping portion 12, so as to form a first notch 310 between the connecting portion 13 and the first limiting portion 31 that is adapted to the shape of the tube body of the flexible tube 2, thereby facilitating and reducing wear between the two.

[0064] Optionally, such as Figure 2 and Figure 3 As shown, the connecting portion 13 of the clamp 10 has a clearance notch 130 on its side near the first limiting portion 31 to avoid the flexible tube 2 being inserted into the first notch 310. This allows the tube body of the flexible tube 2 inserted into the first notch 310 to extend straight to the second notch 320, preventing the connecting portion 13 from bending the flexible tube 2 and ensuring that the flexible tube 2 has a high flow capacity. Optionally, the snap-fit ​​portion 22 of the clamping member 20 may also have a clearance notch on its side near the second limiting portion 32 to prevent the tube body of the flexible tube 2 from being bent by the snap-fit ​​portion 22 and affecting the flow capacity.

[0065] It is understood that the rear side of the latching portion 22 of the latching component 20 is provided with multiple latching platforms to form multiple longitudinally arranged latching positions on the latching portion 22, which facilitates adjustment of the clamping degree of the flexible tube 2 and thus adjusts the flow rate. In addition, the upper surface of the pressing portion 21 of the latching component 20 is provided with anti-slip texture to prevent slippage during pressing, which will not be described in detail in this application.

[0066] It is worth noting that although in the above embodiment, the first limiting part 31 of the improved Robert clip 1 only includes one rear limiting rod 311 to limit the tube body of the flexible tube 2, in other examples of this application, the first limiting part 31 may also include two or more limiting rods, which can still play the role of limiting the tube body of the flexible tube 2.

[0067] Exemplarily, in one modified example of this application, such as Figure 6 As shown, the first limiting portion 31 of the limiting member 30 may include a first limiting rod 312 extending from the first end 131 of the connecting portion 13 toward the second clamping arm 121 and a second limiting rod 313 extending from the second end 132 of the connecting portion 13 toward the first clamping arm 111, so as to form a notch in the first notch hole 310 between the first limiting rod 312 and the second limiting rod 313, so as to facilitate the tube body of the flexible tube 2 being inserted into the first notch hole 310.

[0068] Optionally, such as Figure 6 and Figure 7 As shown, the extension length of the first limiting rod 312 can be equal to the extension length of the second limiting rod 313, so that the notch of the first notch hole 310 is located in the middle of the first limiting portion 31, so that the improved Robert clip 1 can be easily installed onto the flexible tube 2. It is understood that in other examples of this application, the extension length of the first limiting rod 312 and the extension length of the second limiting rod 313 can also be different, as long as they can restrict the flexible tube 2. This application will not elaborate on this further.

[0069] Optionally, such as Figure 6 and Figure 8 As shown, the extension length of the mating rod 123 can be equal to the extension length of the front limiting rod 321, so that the notch of the second notch hole 320 is located in the middle position between the second clamping arm 121 and the first clamping arm 111, so as to further reduce the installation difficulty between the improved Robert clamp 1 and the flexible tube 2.

[0070] Furthermore, in this modified example of this application, such as Figures 6 to 8 As shown, the first clamping block 112 can be integrally connected to the solid protrusion of the first clamping arm 111; similarly, the second clamping block 122 can be integrally connected to another solid protrusion of the second clamping arm 121 to improve the overall structural strength of the first clamping block 112 and the second clamping block 122, prevent them from undergoing large deformation when clamping the flexible tube 2, and obtain a better clamping effect.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
