[0022] As Figures 1-7 shown, the present application provides a self-adaptive dorsal artery monitoring device, which comprises a controller and a power supply, and the controller and the power supply are both prior art, and the specific structure will not be described here. The device also includes a base 10, a sliding block 20, a driving assembly 30, a telescopic assembly 40, a sliding assembly 50, a monitoring assembly 60 and a positioning plate 70.

[0023] The top of the base 10 is provided with a downwardly extending sliding groove 11. The sliding block 20 is arranged in the sliding groove 11 and in sliding contact with the inner wall of the sliding groove 11.

[0024] The driving assembly 30 is used to control the movement of the sliding block 20 in the sliding groove 11.

[0025] The telescopic assembly 40 includes a guide rod 41, a pressing plate 42 and a first spring 43. The guide rod 41 passes through the sliding block 20 in a transverse direction and is in sliding connection with the sliding block 20, and the length direction of the guide rod 41 is perpendicular to the length direction of the sliding groove 11. The pressing plate 42 is fixedly installed at the inner end of the guide rod 41. The first spring 43 is sleeved on the guide rod 41, and the two ends of the first spring 43 are fixedly connected with the sliding block 20 and the pressing plate 42 respectively, and the first spring 43 makes the pressing plate 42 have a tendency to move inward.

[0026] The sliding assembly 50 comprises a guide rail 51, a movable plate 52 and a stop plate 53. The guide rail 51 is fixedly installed on the top of the pressing plate 42, and the length direction of the guide rail 51 is parallel to the length direction of the guide rod 41. The movable plate 52 is arranged on the guide rail 51 and is in sliding connection with the guide rail 51. The stop plate 53 is fixedly installed on the movable plate 52.

[0027] The monitoring assembly 60 comprises a guide column 61, a lifting plate 62, a second spring 9263 and an arterial monitor 64. The guide column 61 penetrates through the inner end of the movable plate 52 in the longitudinal direction and is in sliding connection with the movable plate 52. The lifting plate 62 is fixedly installed on the bottom of the guide column 61. The second spring 9263 is sleeved on the guide column 61, and the two ends of the second spring 9263 are fixedly connected with the lifting plate 62 and the movable plate 52 respectively. The arterial monitor 64 is fixedly installed on the bottom of the lifting plate 62 and is electrically connected with the controller.

[0028] The positioning plate 70 is fixedly installed on the base 10 and is located on the inner side of the pressing plate 42.

[0029] In the initial state, the sliding block 20 is located at one end of the guide groove 15 close to the positioning plate 70.

[0030] The specific use process of the device is as follows: Firstly, the patient places the foot on the base 10, and the positioning plate 70 is located between the big toe and the second toe of the patient's foot. In this way, the foot of the patient is preliminarily positioned.

[0031] Then, the driving assembly 30 is started to control the sliding block 20 to move forward, and under the action of the first spring 43, the pressing plate 42 will be tightly attached to the inner side of the patient's foot (located on the side of the big toe).

[0032] Subsequently, the driving assembly 30 is turned off, the movable plate 52 is moved inward, the stop plate 53 is aligned with the positioning plate 70, and the distance between the arterial monitor 64 and the pressing plate 42 is equal to the width of the big toe of the patient (i.e. the distance between the arterial monitor 64 and the pressing plate 42 is also equal to the distance between the dorsal artery and the pressing plate 42), and the arterial monitor 64 is located just obliquely above the dorsal artery.

[0033] Finally, the driving assembly 30 is started to control the sliding block 20 to continue to move forward, and the arterial monitor 64 is moved to the top of the dorsal artery. At this time, the doctor presses the guide column 61 downward, and the arterial monitor 64 will be in contact with the dorsal artery of the patient, so as to monitor the dorsal artery of the patient.

[0034] The whole operation steps of the device are simple, and the doctor only needs to control the motor 32 to start and press the guide column 61. And due to the design of the first spring 43, no matter the size and shape of the patient's foot, the pressing block will be tightly attached to the inner side of the patient's foot, thereby ensuring that the distance between the artery monitor 64 and the pressing plate 42 is equal to the distance between the dorsal artery and the pressing plate 42, so that the device can adapt to the size and shape of the feet of different patients.

[0035] It is worth noting that the equality in the present application is not the complete equality in the mathematical sense of size accuracy. The dorsal artery is a relatively long and wide artery, and reasonable errors will not affect the normal use of the device.

[0036] In one embodiment, a stabilizing assembly is further included.

[0037] The stabilizing assembly includes an iron sheet 81 and a magnet 82. The iron sheet 81 is fixedly installed on the movable plate 52 in the transverse direction. The magnet 82 is fixedly installed on the pressing plate 42 and is attached to the iron sheet 81.

[0038] In the initial state, the iron sheet 81 is adsorbed together with the magnet 82.

[0039] In the use process of the device, when the doctor moves the movable plate 52 inward so that the baffle 53 is aligned with the positioning plate 70, the iron sheet 81 and the magnet 82 are still adsorbed together, so that the movable plate 52 can always be in a stable state and will not be displaced due to the subsequent start of the driving assembly 30. That is, after the baffle 53 is aligned with the positioning plate 70, the distance between the artery monitor 64 and the pressing plate 42 is always equal to the distance between the dorsal artery and the pressing plate 42.

[0040] In one embodiment, the telescopic assembly 40 further includes a guide wheel 44, which is arranged on the inner side of the pressing plate 42 and is rotatably connected to the bottom of the pressing plate 42.

[0041] In the present embodiment, the guide wheel 44 replaces the pressing plate 42, and when the driving assembly 30 is started, the guide wheel 44 rolls in contact with the inner side of the patient's foot, which can reduce the friction on the inner side of the patient's foot, thereby improving the comfort of the patient.

[0042] In one embodiment, the driving assembly 30 includes a lead screw 31 and a motor 32. The lead screw 31 passes through the sliding block 20 in the transverse direction and is threadedly connected with the sliding block 20. The two ends of the lead screw 31 are rotatably connected with the base 10. The motor 32 is fixedly installed on the base 10 and is electrically connected with the controller. The motor 32 is used to control the rotation of the lead screw 31.

[0043] When the drive component 30 is started, the doctor can start the motor 32 through the control cabinet. The motor 32 drives the lead screw 31 to rotate, and under the action of the slide groove 11, the slider 20 will move back and forth in the slide groove 11.

[0044] In one embodiment, a guide block 12 is also included. The guide block 12 is fixedly mounted on the base 10 and located between the slide groove 11 and the positioning plate 70. An inwardly inclined guide surface 13 is formed on the front side of the guide block 12, and the guide surface 13 contacts the guide wheel 44.

[0045] In the initial state, the guide wheel 44 is in contact with the guide surface 13.

[0046] When this device is in use, the motor 32 starts and drives the lead screw 31 to rotate forward. The slider 20 and the guide rod 41 will drive the pressure plate 42 to move synchronously. At this time, under the action of the first spring 43, the guide wheel 44 will gradually leave the guide surface 13 and stick to the inner side of the patient's foot.

[0047] After the device is used up, the motor 32 starts and drives the lead screw 31 to reverse, and the guide wheel 44 will gradually move away from the inner side of the patient's foot and return to the guide surface 13, thus automatically resetting.

[0048] The design of the guide block 12 and the guide surface 13 allows the guide wheel 44 to automatically leave the guide surface 13 and contact the inner side of the patient's foot when the device is in use. At the same time, after the device is used, the guide wheel 44 can automatically leave the inner side of the patient's foot and return to the guide surface 13.

[0049] In one embodiment, an arc-shaped limiting plate 14 is also included, which is fixedly installed on the base 10, with the opening of the arc-shaped limiting plate 14 facing the positioning plate 70.

[0050] The arc-shaped limiting plate 14 can position the patient's heel and, together with the positioning plate 70, keep the patient's foot stable.

[0051] In one embodiment, both sides of the arc-shaped limiting plate 14 are provided with guide grooves 15 that run horizontally through each other, and each guide groove 15 is provided with a positioning component 90.

[0052] The positioning assembly 90 includes a positioning block 91 and a second spring 9263. The positioning block 91 is disposed within the guide groove 15 and slides in contact with the inner wall of the guide groove 15. The two ends of the second spring 9263 are fixedly connected to the base 10 and the positioning block 91, respectively.

[0053] When the patient puts the heel into the arc-shaped limiting plate 14, the second spring 9263 will press the positioning block 91 on both sides of the heel, so that the heel can be fixed regardless of the width of the patient's heel, further improving the stability of the device.

[0054] In one embodiment, an outwardly convex arc-shaped surface 93 is formed between the top and the inner side of the positioning block 91. In this way, the patient's heel can automatically slide into the two positioning blocks 91 when stepping on the arc-shaped surface 93, so that manual outward pulling of the positioning block 91 is not required, further facilitating use.

[0055] In one embodiment, a display 16 is further included, which is fixedly installed on the base 10 and electrically connected to the controller.

[0056] The data of the dorsalis pedis artery of the patient monitored by the arterial monitor 64 can be directly displayed on the display 16 after processing by the controller, facilitating direct observation by the doctor and the patient.
