Description

Technical Field

[0001] The present application relates to the field of medical auxiliary devices, and specifically to an ECMO pipeline anti-folding device. Background Art

[0002] Extracorporeal membrane oxygenation (ECMO) is mainly used to provide continuous extracorporeal respiration and circulation to patients with severe cardiopulmonary failure to maintain the patient's life. ECMO equipment mainly includes intravascular cannula, connecting tube, power pump (artificial heart), oxygenator (artificial lung), oxygen supply tube, monitoring system and other parts. The inventor found in clinical practice that ECMO pipeline, especially a section coming out of the power pump, needs to extend upward and forward, and the pipeline is a hose. Under the influence of gravity, this part of the pipeline is prone to narrowing or even folding, affecting the smooth transportation of the pipeline. In this case, a commonly used solution is to tie one end of a rope or belt to the bending part or next to it, and then pull it up, but because the binding area of ​​the rope or belt is small and it is also a soft material, it is still difficult to fully restore the normal shape of the bending part, and the complete smooth transportation of the pipeline cannot be ensured. Utility Model Content

[0003] The purpose of this application is to provide an ECMO tube anti-folding device, which can restore the normal shape of the part of the tube that is easy to fold during use, and ensure the smooth transportation of the tube. To this end, this application provides the following technical solutions:

[0020] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the application content of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0021] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0022] like Figures 1 to 5 As shown, the ECMO pipeline anti-bend device of the embodiment of the present application includes a base 10, a tube clamp 20 and a connector 30. Among them, the base 10 includes a U-shaped sleeve 11 and a receiving block 12 arranged outside the U-shaped sleeve 11; the U-shaped sleeve 11 is threadedly connected with a first screw 13 at a position close to its opening, and the head and front end of the first screw 13 are respectively located outside and inside the opening of the U-shaped sleeve 11; the receiving block 12 is provided with a first through hole 14 that runs through from top to bottom, and a support rod 15 is slidably connected in the first through hole 14, and a second screw 19 is threadedly connected to the side of the receiving block 12, and the second screw 19 is used to fasten the support rod 15 to the receiving block 12. The pipe clamp 20 includes two arc-shaped clamping plates 21, one end of which is hinged to each other, and a spring 22 is provided at the hinged position. The spring 22 makes the first two tend to close together to form a cylindrical shape through elastic force. A force plate 23 extends from the hinged edge of the clamping plate 21. The two force plates 23 are in an open state when the two clamping plates 21 are closed. The two ends of the connecting member 30 are respectively provided with a second through hole 31 and a slot 32; the second through hole 31 is used to pass through the upper end of the support rod 15, and the outer side thereof is threadedly connected with a third screw 33, and the third screw 33 is used to fasten the connecting member 30 to the support rod 15; the slot 32 is parallel to the axial direction of the second through hole 31, and is used to clamp one of the force plates 23.

[0023] When the device is in use, the tube clamp 20 can be removed and used alone. After opening the tube clamp 20 with reference to the method of using a general clamp, let it wrap around the part of the ECMO pipeline that is easy to fold. Due to factors such as gravity and the softness of the tube, the folded part is generally a relatively fixed position. After wrapping the tube clamp 20 around this part, the influence of the gravity of the pipeline can be dispersed, so that the pipeline can return to a normal state. The internal size of the tube clamp 20 can be larger than the diameter of the pipeline, so that the pipeline can maintain a certain bending but not folded or narrowed state when it comes out of the tube clamp 20. The tube clamp 20 can also be used in conjunction with the base 10 and the connector 30. The base 10 can be installed on the power pump through the first screw 13 and the U-shaped sleeve 11. The supported position of the tube clamp 20 can be adjusted by the coordinated use of the second screw 19, the third screw 33 and the support rod 15. After the tube clamp 20 is wrapped outside the pipeline, the force plate 23 of the tube clamp 20 is clamped into the slot 32 of the connector 30.

[0024] Furthermore, a soft rubber layer 16 is provided on the inner side of the U-shaped sleeve 11. The soft rubber layer 16 can be made of a rubber-plastic material (such as rubber) with a certain elastic deformation ability, and is used to clamp the base 10 on the pump head more stably when it is installed on the power pump. Furthermore, an anti-slip block 17 is fixed to the front end of the first screw 13, and the anti-slip block 17 is made of a flexible material, and its end surface is provided with anti-slip corrugations. The flexible material used to make the anti-slip block 17 can be made of materials such as silicone, which can play a better tightening role after tightening the first screw 13.

[0025] Furthermore, the side wall of the support rod 15 is provided with a limiting groove 18 parallel to the axial direction, and the inner walls of the first through hole 14 and the second through hole 31 are provided with limiting convex strips 34 parallel to the axial direction; the limiting convex strips 34 are slidably connected in the limiting groove 18 to keep the slot 32 always located directly above the U-shaped sleeve 11. In this way, the support rod 15 will not rotate easily, and the slot 32 can always be located directly above the U-shaped sleeve 11, and the pipe clamp 20 can be kept directly above the U-shaped sleeve 11, ensuring smooth deployment of the pipeline.

[0026] Furthermore, the force plate 23 is provided with a clamping hole 24, and an inner side wall of the slot 32 is provided with a clamping protrusion 35; when the force plate 23 is inserted into the slot 32, the clamping protrusion 35 is clamped in the clamping hole 24. Through the cooperation between the clamping protrusion 35 and the clamping hole 24, the pipe clamp 20 after being plugged in will not fall off or shift from the connector 30 easily, thereby ensuring stability during use.

[0027] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of the present application should all be within the protection scope of the present application.
