[0002] Various medical devices are connected by a complex network of tubing. These tubing not only transmit vital medical media but also carry out signal transmission and other functions. An effective instrument tubing restraint and positioning device can ensure that these tubings are neatly arranged, preventing tangling, pulling, or compression, thereby ensuring the normal operation of medical equipment, reducing the risk of equipment failure due to tubing problems, and also providing convenience for medical staff, improving the efficiency and safety of medical work.

[0003] Currently, existing instrument tubing constraint and positioning devices have some shortcomings: the structure of most devices is relatively fixed, the spacing of the clamping components cannot be flexibly adjusted, it is difficult to adapt to tubing of different specifications and quantities, and it is easy to cause some tubing to be unable to be effectively constrained. Therefore, an instrument tubing constraint and positioning device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an instrument pipeline constraint positioning device, which aims to improve the problem that the structure of most existing devices is relatively fixed and the spacing of the clamping components cannot be flexibly adjusted.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The inner wall of the rear end of the fixing frame is elastically connected to a limit ball through a return spring.

[0010] As a further description of the above technical solution:

[0011] The screw passes through and is rotatably connected to the inner wall of the top of the fixed frame, and the slider is slidably connected to the inner wall of the fixed frame.

[0012] As a further description of the above technical solution:

[0013] The connecting plate is slidably connected to the top of the inner side wall of the fixing frame, and the insert block is slidably connected to the inner wall of the clamping plate b.

[0014] As a further description of the above technical solution:

[0015] One end of the limiting spring is fixedly connected to the outer wall of the insert block, and the other end of the limiting spring is fixedly connected to the inner wall of the clamping plate b.

[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the movement of multiple sets of clamping plates b can be easily realized by rotating the screw, so that they can be tightly matched with clamping plates a to firmly constrain the wiring pipes of medical equipment. At the same time, the design of the plug and limiting spring on the clamping plate b allows the position of the clamping plate b to be flexibly adjusted when facing wire harnesses of different thicknesses, ensuring that multiple sets of wire harnesses of different thicknesses can be properly clamped and constrained.

[0024] 2. In this utility model, the fixing plate can be precisely adjusted according to the inclination of the fixed position through the cooperation of the limiting ball and the return spring. When the fixing plate rotates to the appropriate angle, the limiting ball can automatically reset and fix its position, ensuring that the fixing plate will not rotate randomly without the action of external force, effectively avoiding the instrument pipeline being pulled. In addition, the design of the bidirectional threaded rod and the clamping seat enables the device to be firmly fixed on the outside of the equipment or in the position of the hospital bed.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 - Figure 3This utility model provides an embodiment of an instrument tubing constraint and positioning device, including a fixed frame 1. Three sets of clamping plates a 2 are fixedly connected to the surface of the fixed frame 1. A guide groove is opened on the surface of the fixed frame 1. A clamping plate b 3 is slidably connected to the inner wall of the guide groove of the fixed frame 1. By the movement of the three sets of clamping plates b 3 and their proximity to the clamping plates a 2, the wiring and tubing connected to the medical equipment can be constrained and pressed. At the same time, the three sets of clamping plates b 3 can only slide laterally in the guide groove on the surface of the fixed frame 1 and cannot detach from its inner wall. A fixed plate 5 is rotatably connected to the rear end surface of the fixed frame 1. A clamping mechanism 4 is provided on the inner side wall of the fixed frame 1.

[0036] Specifically, the wire clamps a2 and b3 are semi-circular and fit together.

[0037] Reference Figure 3 - Figure 5 The clamping mechanism 4 includes a screw 41, which is rotatably connected to the inner wall of the top of the fixed frame 1. A triangular block is provided at the top of the screw 41, which facilitates the rotation of the screw 41 as a whole. A slider 42 is slidably connected to the inner wall of the fixed frame 1. The slider 42 is threadedly connected to the surface of the screw 41. The inner side of the slider 42 has an internal thread groove that matches the screw 41, so that when the screw 41 rotates, the slider 42 can move up and down on its surface. It contacts the outer wall of the slider 42 through the inner side wall of the fixed frame 1, thereby guiding the upward movement of the slider 42. A hinge rod 43 is hinged to the surface of the slider 42. The end of the hinge rod 43 away from the slider 42 is hinged to a... The connecting plate 44 is slidably connected to the top of the inner side wall of the fixed frame 1. When the slider 42 moves up and down, it will pull the corresponding connecting plate 44 to move synchronously through the hinge rod 43, thereby driving the clamping plate b3 fixed on its surface to move synchronously, so as to clamp and constrain the instrument's pipelines, etc. The inner wall of the rear end of the clamping plate b3 is elastically connected to the insert 9 through the limiting spring 8. One end of the limiting spring 8 is fixedly connected to the outer wall of the insert 9, and the other end of the limiting spring 8 is fixedly connected to the inner wall of the clamping plate b3. The function of the limiting spring 8 is to automatically reset the position of the insert 9 after it is pulled, and also to provide elastic support for the position of the insert 9. The insert 9 is slidably connected to the clamping plate b3. The inner wall of the 3 and the surface of the connecting plate 44 are provided with through holes. The outer wall of the insert 9 is inserted into the inner wall of the through hole. The insertion between the two can adjust the position of a single set of clamping plates b 3 on the surface of the connecting plate 44, so that the movement of the connecting plate 44 can simultaneously clamp and constrain multiple sets of wire harnesses of different thicknesses.

[0038] Reference Figure 2 and Figure 5 - Figure 7The inner wall of the fixing plate 5 is rotatably connected to a bidirectional threaded rod 6. Two sets of clamping seats 7 are threaded onto the surface of the bidirectional threaded rod 6. The inner side of each clamping seat 7 has an internal thread, and the surface of the bidirectional threaded rod 6 has two sets of threads with opposite directions. By rotating the bidirectional threaded rod 6, the two sets of clamping seats 7 can be brought closer together, thus fixing the entire unit to the outside of the equipment or to a hospital bed. The clamping seats 7 are slidably connected to the surface of the fixing plate 5. A ball groove is formed on the outer arc surface of the center point of the rear end of the fixing plate 5. The outer wall of the limiting ball 11 contacts the inner wall of the ball groove. This contact allows the fixing plate 5 to be fixed at multiple positions as the rear end of the fixing frame 1 rotates. The spherical design of the time-limiting ball 11 ensures that the fixing plate 5 will not rotate without external force. The inner wall of the rear end of the fixing frame 1 is elastically connected to the time-limiting ball 11 via a return spring 10. One end of the return spring 10 is fixedly connected to the outer wall of the time-limiting ball 11, and the other end is fixedly connected to the inner wall of the rear end of the fixing frame 1. The function of the return spring 10 is to automatically reset the position of the time-limiting ball 11 after it has been squeezed and moved by the inner wall of the ball groove at the rear end of the fixing plate 5. Furthermore, by rotating the fixing plate 5, the position can be adjusted according to the inclination of the fixed position, thus preventing the instrument lines from being pulled. The time-limiting ball 11 is slidably connected to the inner wall of the rear end of the fixing frame 1.

[0039] Working principle: When it is necessary to constrain the instrument tubing, the triangular block at the top of the rotating screw 41 drives the screw 41 to rotate. Since the inner side of the slider 42 has an internal thread groove that fits with the screw 41, when the screw 41 rotates, the slider 42 moves up and down along the surface of the screw 41 on the inner wall of the fixed frame 1. The inner wall of the fixed frame 1 guides the slider 42 to rise. When the slider 42 moves up and down, it drives the connecting plate 44 to move synchronously through the hinge rod 43, which in turn drives the clamping plate b 3 to slide laterally in the guide groove of the fixed frame 1, so that the clamping plate b 3 moves closer to the clamping plate a. In this way, the wiring tubing of the medical equipment can be constrained and compressed between the clamping plates a 2 and b 3.

[0040] Furthermore, when dealing with wire harnesses of different thicknesses, the plug 9 can be pulled to overcome the elasticity of the limiting spring 8 and disengage from the through hole on the surface of the connecting plate 44. The position of a certain set of clamping plates b3 on the surface of the connecting plate 44 can be adjusted individually. After adjustment, the plug 9 can be released, and the limiting spring 8 will automatically reset and insert it into the through hole of the connecting plate 44, thereby achieving the clamping constraint of multiple sets of wire harnesses of different thicknesses. At the same time, when the connecting plate 44 moves the three sets of clamping plates b3 synchronously next time, one of the already adjusted sets will clamp and fix the current wire harness.

[0041] When the angle of the fixing plate 5 needs to be adjusted according to the inclination of the fixed position, an external force is applied to make the fixing plate 5 rotate. During the rotation of the fixing plate 5, the inner wall of the ball groove at its rear end presses the limiting ball 11. The limiting ball 11 overcomes the elastic force of the return spring 10 and moves towards the inner wall of the rear end of the fixing frame 1. When the fixing plate 5 rotates to the appropriate angle, the external force is released, and the return spring 10 makes the limiting ball 11 automatically return to its original position. Its outer wall contacts the inner wall of the ball groove at the rear end of the fixing plate 5 again, thereby fixing the fixing plate 5 in this position and preventing the instrument pipeline from being pulled. Due to the spherical setting of the limiting ball 11, the fixing plate 5 will not rotate arbitrarily when there is no external force, ensuring the stability of the device angle. The bidirectional threaded rod 6 is rotated. Since the two sets of threads on the surface of the bidirectional threaded rod 6 have opposite directions of rotation, and the inner side of the clamping seat 7 has internal threads that cooperate with the bidirectional threaded rod 6, the rotation of the bidirectional threaded rod 6 makes the two sets of clamping seats 7 move closer to each other, thereby firmly fixing the device in the target position.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
