[0023] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0024] like Figures 1 to 5 As shown, this embodiment proposes a sensor for continuous cardiac output measurement, including a sensor 1 and a power cord 101 arranged on the sensor 1, a movable component for adjusting the power cord 101 is arranged on the sensor 1, and the movable component includes a movable frame 3, a connector 301 arranged on the movable frame 3, a fixed frame 2 arranged on the end face of the sensor 1, and rollers 4 arranged on the inner bottom walls on both sides of the fixed frame 2, the connector 301 is rotatably connected to the surface of the fixed frame 2, the power cord 101 passes through the fixed frame 2 and the movable frame 3 and extends outward, and the power cord 101 passes through the middle of the two groups of rollers 4, and a positioning component for fixing the power cord 101 is also arranged inside the movable frame 3;

[0025] The power cord 101 passes through the movable frame 3 and the fixed frame 2 and is connected to the sensor 1. When the angle of the power cord 101 on the sensor 1 needs to be adjusted, it is only necessary to rotate the movable frame 3 to drive the power cord 101 to bend and adjust the angle. At this time, the power cord 101 will contact the roller 4 when being bent. The roller 4 can prevent the power cord 101 from being bent too much, thereby preventing the power cord 101 from being damaged. In addition, the positioning component can clamp and fix the part of the power cord 101 inside the movable frame 3, thereby preventing the power cord 101 from being pulled and separated from the sensor 1.

[0026] Among them, the inner walls on both sides of the fixed frame 2 are rotatably connected with a rotating column 201, and the roller 4 fixing sleeve is set on the rotating column 201; the power cord 101 can be rolled on the roller 4 by rotating the roller 4, thereby reducing the friction between the roller 4 and the power cord 101, and further preventing the power cord 101 from being damaged.

[0027] In addition, a mounting opening 202 is provided at one end of the fixed frame 2 close to the sensor 1 , and an anti-skid groove 303 is provided on the surface of the movable frame 3 ; the anti-skid groove 303 is provided to facilitate personnel to stably rotate the movable frame 3 .

[0028] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the positioning assembly includes a slide bar 5 slidably arranged on the side walls at both ends of the movable frame 3, a clamping block 6 rotatably arranged on one end of the slide bar 5 located inside the movable frame 3, a turning handle 502 fixedly arranged on one end of the slide bar 5 located outside the movable frame 3, and a support plate 302 arranged on both sides of the inner bottom wall of the movable frame 3, the slide bar 5 is slidably connected with the support plate 302, a spring 501 is sleeved on the rod wall of the slide bar 5 located between the clamping block 6 and the support plate 302, and a limiter is also provided on the slide bar 5;

[0029] The limiting member includes a stopper 7 horizontally arranged on the rod walls on both sides of the slide rod 5, and a vertical slot 8 is arranged on the side wall of the movable frame 3, and the slot 8 is matched with the stopper 7;

[0030] The slide bar 5 is rotated to make the block 7 coincide with the slot 8, and then by squeezing the slide bars 5 on both sides of the movable frame 3, the two groups of clamping blocks 6 can be driven to move closer to each other to clamp the power cord 101, and the moving slide bar 5 will also squeeze the spring 501. At this time, the slide bar 5 is rotated again to make the block 7 and the slot 8 misaligned, thereby preventing the spring 501 from driving the slide bar 5 to rebound and reset. When the power cord 101 needs to be released, the slide bar 5 is rotated again to make the block 7 coincide with the slot 8 again, and the spring 501 will be released by the force to drive the slide bar 5 to rebound and reset and make the clamping block 6 separate from the power cord 101, thereby quickly releasing the power cord 101.

[0031] like Figure 4 and Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a rotating shaft 901 passing through the fixed frame 2 and extending to the inside thereof is provided at the bottom of the connector 301, a toothed disc 9 is provided on the rotating shaft 901, and a latching tooth 10 meshing with the toothed disc 9 is provided on the inner wall of the fixed frame 2, and both the toothed disc 9 and the latching tooth 10 are made of rubber material;

[0032] When the movable frame 3 is rotated to adjust the angle position of the power cord 101, the connector 301 on the movable frame 3 will drive the toothed disc 9 to rotate. Because the toothed disc 9 and the latch teeth 10 are made of rubber, the toothed disc 9 will push aside the latch teeth 10 and continue to rotate when it is rotated manually. When the angle position of the power cord 101 is adjusted, the movable frame 3 is released. At this time, the shapes of the toothed disc 9 and the latch teeth 10 will be reset and meshed together again, so as to limit the movable frame 3 and the power cord 101 with the adjusted angle position.

[0033] The working principle of the utility model is as follows: the power line 101 is passed through the movable frame 3 and the fixed frame 2 and connected to the sensor 1. When the angle of the power line 101 on the sensor 1 needs to be adjusted, the movable frame 3 only needs to be rotated, so that the power line 101 can be driven to bend and adjust the angle. At this time, the power line 101 will contact the roller 4 when being bent. The roller 4 can prevent the power line 101 from being bent too much, thereby preventing the power line 101 from being damaged. In addition, the slide bar 5 can be rotated first to make the block 7 overlap with the slot 8, and then by squeezing the slide bars 5 on both sides of the movable frame 3, the two groups of clamping blocks 6 can be driven to move closer to each other to clamp the power line 101, and the moving slide bar 5 will also squeeze the spring 501. At this time, the slide bar 5 is rotated again to make the block 7 and the slot 8 misaligned, thereby preventing the spring 501 from driving the slide bar 5 to rebound and reset, thereby clamping and fixing the part of the power line 101 located inside the movable frame 3, so that the power line 101 can be prevented from being pulled and separated from the sensor 1.

[0034] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
