Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to an auxiliary device for connecting a drainage bag. Background Art

[0002] Clinically, drainage tubes and drainage bags connected to the drainage tubes through connectors are commonly used. Generally, the inner diameter of the drainage tube is not greater than the outer diameter of the connector of the drainage bag. When in use, one end of the drainage tube is inserted into the part of the patient that needs drainage, and the other end of the drainage tube is connected to the connector of the drainage bag, so as to convey the substance to be drained into the drainage bag. However, according to different requirements for drainage tubes for different diseases, there are many types and specifications of drainage bags available for purchase. The calibers and external interface styles of drainage tubes produced by different manufacturers may vary. Moreover, there is a situation where a patient has a drainage tube placed in one hospital and then goes to another hospital for treatment. Therefore, there is a phenomenon that the connector of the drainage tube does not match the connector of the drainage bag, which directly leads to the inability to insert the connector of the drainage bag into the drainage tube, and is not conducive to the treatment and recovery of the patient.

[0003] Therefore, a device that can assist in connecting the connector of the drainage bag to drainage tubes with different inner diameters is designed, and this device is specifically an auxiliary device for connecting a drainage bag. Summary of the Utility Model

[0004] In order to overcome the problems raised in the background art, the utility model adopts the following technical solutions:

[0005] An auxiliary device for connecting a drainage bag, which includes a sleeve and a spreading hook; several elastic arms are connected to one end of the sleeve; the spreading hook includes a connecting part and an expanding part, the connecting part is connected to the elastic arms, and the end of the expanding part always points to the end of the sleeve where the elastic arms are arranged. When the elastic arms are not subject to external forces, the spreading hook is maintained in a spreading position, and when the spreading hook leaves the spreading position, it has a tendency to return to the spreading position driven by the elastic arms.

[0006] Further, an insertion channel is provided inside the sleeve, the elastic arms are distributed in a circular array on the side wall of the sleeve around the central axis of the insertion channel, and when the elastic arms are deformed, the plane where any point of the movement path is located is parallel to the central axis of the insertion channel, and the bending direction of each elastic arm is relatively fixed, so that the drainage tube can be stably spread when in use.

[0007] Further, the spreading hook can move to an insertion position, and when all the spreading hooks move to the insertion position, the adjacent expanding parts are in contact with each other.

[0008] Further, when the spreading hook is in the inserted position, the distance between the end of the expansion part and the central axis of the sleeve is the shortest. When the spreading hook is in the inserted position, the expansion parts approach and close to each other. When the drainage tube moves through the insertion channel towards the expansion part, it can be sleeved on the expansion part. At this time, when the external force applied to the elastic arm is removed, the spreading hook moves towards the spreading position and expands the nozzle of the drainage tube, so that the connector of the drainage bag can be inserted into the drainage tube.

[0009] Further, a slot is provided in the connecting part, and the elastic arm is inserted and connected to the spreading hook through the slot. After the elastic arm is inserted into the slot, it has an interference fit with the slot to prevent the spreading hook from detaching from the elastic arm during use.

[0010] Further, an opening is provided through the side wall of the sleeve along the central axis direction of the sleeve, and the sleeve is elastic. The opening is always closed without external force, and has a tendency to close when opened. The sleeve can be sleeved or clamped on drainage tubes with different diameters through the opening, and can also be detached radially along the drainage tube after the drainage tube is connected to the connector of the drainage bag.

[0011] Further, the cross-sectional area at any position on the expansion part is smaller than the cross-sectional area at any position on the connecting part. From the end of the connecting part facing the sleeve to the end of the expansion part facing the sleeve, the cross-sectional area of the spreading hook gradually decreases.

[0012] Further, the diameter of the insertion channel is not less than 5 mm.

[0013] Further, the number of the elastic arms is not less than two, and each elastic arm is exactly the same. The distance between adjacent elastic arms is the same, so that the elastic arms can be evenly stressed when the spreading hook expands the drainage tube.

[0014] Further, the number of the spreading hooks is the same as the number of the elastic arms, and each spreading hook is exactly the same, so that the contact area between each expansion part and the inner wall of the drainage tube is the same when the spreading hook expands the drainage tube.

[0015] The beneficial effects of the present utility model:

[0016] By providing an elastic arm that can be bent and has elasticity and a spreading hook connecting the elastic arms, the expansion part of the spreading hook can be inserted into the drainage tube passing through the sleeve and expand the interface of the drainage tube under the drive of the elastic arm, so that the connector of the drainage bag can be inserted into drainage tubes with different inner diameters and connected to the drainage tube; by providing an opening on the sleeve, the sleeve can be detached radially along the drainage tube after the connector of the drainage bag is connected to the drainage tube, which is convenient to use and has a simple structure, and has excellent practical effects.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] A drainage bag connection assisting device, such as Figures 1-5As shown, it includes a sleeve 1 and a spreading hook 2; a plurality of elastic arms 11 are connected to one end of the sleeve 1; the spreading hook 2 includes a connecting portion 21 and an expansion portion 22, the connecting portion 21 is connected to the elastic arm 11, and the end of the expansion portion 22 always points to the end of the sleeve 1 provided with the elastic arm 11, and the elastic arm 11 maintains the spreading hook 2 in an expanded position when not subject to external force, and when the spreading hook 2 leaves the expanded position, it has a movement tendency driven by the elastic arm 11 to return to the expanded position. The expansion hook 2 is specifically an n-shaped hook-shaped body, and the connecting part 21 is parallel to the central axis of the expansion part 22. The sleeve 1 is made of elastic plastic or nylon, which makes the elastic force of the elastic arm 11 to reset greater than the elastic force when the opening 13 of the sleeve 1 is closed, and the user can more easily remove the sleeve 1 from the drainage tube. The elastic arm 11 is fixedly connected to the sleeve 1. The elastic arm 11 is specifically a metal sheet or a metal strip. More specifically, the elastic arm 11 is made of aluminum alloy or iron alloy. When in use, the user tightly grasps the expansion hook 2 to make the expansion part 22 close together, so that the drainage tube passing through the sleeve 1 can cover the expansion part 22. After the user removes the constraint on the expansion hook 2, the expansion hook 2 expands the drainage tube under the drive of the elastic arm 11, so that the connector of the drainage bag can enter.

[0026] In some embodiments of the present application, Figures 1-5 As shown, there is an insertion channel 12 in the sleeve 1, the diameter of the insertion channel 12 is not less than 5 mm, and the elastic arms 11 are distributed in a circular array on the side wall of the sleeve 1 around the central axis of the insertion channel 12. When the elastic arms 11 are deformed, the plane where the movement path of any point thereof is located is parallel to the central axis of the insertion channel 12, and the bending direction of each elastic arm 11 is relatively fixed, so that the drainage tube can be stably propped open when in use.

[0027] In some embodiments of the present application, Figures 1-5 As shown, the expansion hook 2 can move to an insertion position, and when all the expansion hooks 2 move to the insertion position, the adjacent expansion parts 22 contact each other. When the expansion hook 2 is in the insertion position, the distance between the end of the expansion part 22 and the central axis of the sleeve 1 is the shortest. When the expansion hook 2 is in the insertion position, each expansion part 22 is close to each other and closed. When the drainage tube passes through the insertion channel 12 and moves toward the expansion part 22, it can be sleeved with the expansion part 22. At this time, the external force applied to the elastic arm 11 is removed, and the expansion hook 2 moves to the expansion position and expands the tube mouth of the drainage tube, so that the connector of the drainage bag can be inserted into the drainage tube.

[0028] In some embodiments of the present application, Figures 1-5 As shown, a slot 211 is provided in the connecting portion 21, and the elastic arm 11 is plugged and connected to the opening hook 2 through the slot 211. After the elastic arm 11 is inserted into the slot 211, it has an interference fit with the slot 211 to prevent the opening hook 2 from separating from the elastic arm 11 during use.

[0029] In some embodiments of the present application, as Figures 1-5 shown, an opening 13 is provided through the side wall of the sleeve 1 along the central axis direction of the sleeve 1, and the sleeve 1 is elastic. The opening 13 is always closed when not subjected to external force, and has a tendency to close when the opening 13 is opened. The sleeve 1 can be sleeved or clamped on drainage tubes with different diameters through the opening 13, and can also be detached radially along the drainage tube after the connection between the drainage tube and the drainage bag joint.

[0030] In some embodiments of the present application, as Figures 1-5 shown, the cross-sectional area at any position on the expansion part 22 is smaller than the cross-sectional area at any position on the connection part 21. From the end of the connection part 21 facing the sleeve 1 to the end of the expansion part 22 facing the sleeve 1, the cross-sectional area of the spreading hook 2 gradually decreases, so as to improve the connection strength between the connection part 21 and the elastic arm 11 during use and make the expansion part 22 easier to enter the drainage tube with a small diameter.

[0031] In some embodiments of the present application, as Figures 1-5 shown, the number of the elastic arms 11 is not less than two, each elastic arm 11 is exactly the same, and the distance between adjacent elastic arms 11 is the same, so that the elastic arms 11 can be evenly stressed when the spreading hook 2 expands the drainage tube. The number of the spreading hooks 2 is the same as the number of the elastic arms 11, and each spreading hook 2 is exactly the same, so that the contact area between each expansion part 22 and the inner wall of the drainage tube is the same when the spreading hook 2 expands the drainage tube.
