Description

Technical Field

[0001] The utility model relates to the technical field of perfusion devices, in particular to a double-head clamp for a blood perfusion device. Background Art

[0002] Hemoperfusion devices are used to treat a variety of blood-related conditions, particularly in cases of acute or chronic poisoning. They filter blood outside the body to remove harmful substances, such as toxins and metabolic products, and then return the purified blood to the body. They play an important role in both emergency medical care and the treatment of chronic diseases.

[0003] In the existing technology, although the existing clamps can meet the needs of blood perfusion operations to a certain extent, they still have many shortcomings in actual use. First, traditional clamps can usually only clamp one perfusion device, which means that when multiple perfusion devices are needed, medical staff need to frequently operate different clamps, increasing the complexity and workload of the operation. In addition, since the appearance of the perfusion device is usually bulky, the clamp is prone to loosening during the clamping process, especially when the position of the perfusion device needs to be adjusted during operation, the stability of the clamp is difficult to ensure. This may not only cause the position of the perfusion device to shift, affecting the treatment effect, but may also increase the patient's discomfort and potential risks. Utility Model Content

One side of 0 is fixedly connected to one end of the spring 113, the other end of the spring 113 is provided with an outer ring 112, the other end of the spring 113 is fixedly connected to one end of the outer ring 112, the inner side of the outer ring 112 is provided with a ball head 111, the inner side of the outer ring 112 is in sliding contact with the top of the ball head 111, the bottom end of the ball head 111 is vertically connected to the inner wall of the fixed tube 110, the bottom end of the ball head 111 is clamped with the outer recess of the mobile tube 17, one end of the connecting plate 14 is provided with a side plate 13, one end of the connecting plate 14 is in contact with the side plate 13 One side of the side panel 13 is fixedly connected, a fixing plate 12 is provided on the other side of the side panel 13, and the other side of the side panel 13 is in contact with one side of the fixing plate 12. A fixing piece 114 is provided on the inner wall of the fixing plate 12, and the inner wall of the fixing plate 12 is threadedly connected to the outer side of one end of the fixing piece 114. The outer side of the fixing piece 114 is threadedly connected to the inner wall of the side panel 13.

[0026] In this embodiment, when using the double-head clamp for this type of blood perfusion device, traditional operation often requires the use of two perfusion devices and one dialyzer. However, during operation, the perfusion device is relatively fat, and the clamp is difficult to clamp the perfusion device and is easily loosened. Since there is only one clamp, it can only clamp one perfusion device. Therefore, a hollow tube 11 is designed, and the two hollow tubes 11 have the same components symmetrically on both sides. Then, during operation, the perfusion device is placed in the locking clamp 19. At this time, the movable tube 17 is pushed on the connecting plate 14, so that during the pushing process, the I-plate 15 drives the folding rod 18 on the locking clamp 19 to change its angle, and the space at the clamping end of the locking clamp 19 is It will gradually shrink. During the movement of the mobile tube 17, the outer ring 112 on the fixed tube 110 needs to be pushed so that it no longer resists the top of the ball head 111. When the mobile tube 17 enters the fixed tube 110, the external force on the outer ring 112 is released, and the spring 113 is elastically released to push the outer ring 112 back. At the same time, the ball head 111 retreats again under the external force and enters the mobile tube 17 to restrict the mobile tube 17. In this way, the locking clamp 19 can tightly clamp the perfusion device after clamping it, thereby enhancing the stability of the clamping and avoiding loosening. At the same time, it allows the user to clamp two perfusion devices in a single operation, thereby improving the convenience of operation.

[0029] In this embodiment, a transverse plate 21 is installed on the mobile tube 17, and the transverse plate 21 is provided with an anti-slip pad 22. In this way, during the process of pushing the mobile tube 17, the anti-slip function can reduce the risk of inaccurate operation caused by sliding, ensuring that the position and force of the mobile tube 17 can be better controlled each time it is pushed. The transverse plate 21 can provide stable support and bearing capacity. When pushing or operating the mobile tube 17, the transverse plate 21 can effectively disperse the applied force to ensure uniform force, thereby improving the stability of the entire structure and the accuracy of operation.
