Description

Technical Field

[0001] The present invention belongs to the research field of health detection technologies, and particularly relates to a dorsalis pedis artery monitoring device. Background Art

[0002] Under normal circumstances, the dorsalis pedis artery should beat along with the heartbeat. Since the dorsalis pedis artery is located relatively superficially on the human body surface, it is easy to be felt. A normal dorsalis pedis artery pulsation indicates sufficient blood in the human body, a strong heartbeat, normal heart function, and no stenosis or occlusion of the arterial blood vessels. If the arterial pulsation cannot be felt, it indicates a serious condition, such as heart failure, insufficient blood volume, etc.; in addition, if there is atherosclerosis, the dorsalis pedis artery pulsation cannot be felt either. The causes of the disappearance of the dorsalis pedis artery pulsation also include diseases such as arteriosclerosis, arterial embolism, arterial injury, and arterial inflammation. In order to dynamically monitor the condition of the lower limb circulation, which is reflected by the strength of the dorsalis pedis artery pulsation, it is necessary to accurately and objectively monitor the strength of the vascular pulsation pressure. In short, by feeling the dorsalis pedis artery pulsation, diseases can be detected early, and it is extremely important to perform early intervention and treatment for the diseases. Currently, in order to facilitate the detection of the dorsalis pedis artery, some strap members are usually used to directly fix a pulse sensor, etc. to the dorsalis pedis artery for detection. In this way, the fixation is not reliable and is prone to displacement. Especially during the movement of the patient, it is easy to move, resulting in difficulty in performing long-term real-time monitoring.

[0003] A patent with the publication number CN113940639A discloses a dorsalis pedis artery monitoring device, including: a sock, the sock having a heel part and a strap part connected to the front end of the heel part; a pulse sensor is provided on the strap part; a monitor is detachably connected to the sock and is connected to the pulse sensor through a connecting wire; when the sock is worn on the patient's foot, the strap part is adapted to be fastened to the patient's instep so that the pulse sensor adheres to the dorsalis pedis artery.

[0004] In the above technical solution, the first suction cup and the second suction cup are respectively arranged on both sides of the pulse sensor, and the first suction cup and the second suction cup respectively adsorb on the body surface on both sides of the dorsalis pedis artery to ensure that the pulse sensor does not shift. However, in actual application, there is grease and sweat on the skin surface of the patient respectively, and the suction force of the first suction cup and the second suction cup is not firm. If the patient's foot moves during the monitoring process, it cannot be guaranteed that the pulse sensor does not shift, and the use effect is not good. Summary of the Invention

[0014] The linkage channel is connected with the sleeve seat;

[0015] The pressing plate controller and the limiting plate controller are connected through gears, and both the pressing plate controller and the limiting plate controller are connected to the linkage channel.

[0016] The above technical solution is further limited in that the pressing plate controller and the limiting plate controller are both telescopic rods.

[0017] The above technical solution is further limited in that the linkage channel is an L-shaped structure, and a clearance groove is provided in the horizontal direction thereof.

[0018] For further limitation of the above technical solution, the two pressing plates oppositely arranged on the foot accommodation seat are respectively: a first pressing plate and a second pressing plate;

[0021] For further limitation of the above technical solution, an auxiliary presser is provided on the side of the second pressing plate; the auxiliary presser includes: an auxiliary pressing rod, an adjusting screw rod and a base;

[0022] One end of the auxiliary pressing rod is connected to the second pressing plate, and the other end is connected to the adjusting screw rod;

[0023] The end of the adjusting screw rod away from the auxiliary pressing rod is connected to the base; the adjusting screw rod is used to press the second pressing plate against the first pressing plate through the auxiliary pressing rod.

[0024] For further limitation of the above technical solution, both the first pressing plate and the second pressing plate are arc-shaped plates.

[0025] For further limitation of the above technical solution, an ankle fixator is further provided on the ankle fixing sleeve.

[0026] For further limitation of the above technical solution, the ankle fixator includes an upper ankle clamping ring, a lower ankle clamping rod and a clamp;

[0027] Both the upper ankle clamping ring and the lower ankle clamping rod are connected to the clamp.

[0028] For further limitation of the above technical solution, the clamp includes a folding rod and an opening adjusting rod;

[0029] Both ends of the folding rod are respectively connected to the ends of the upper ankle clamping ring;

[0030] The opening adjusting rod is arranged on the folding rod and is connected to the lower ankle clamping rod.

[0031] An operation method of a dorsal artery monitoring device, applicable to the dorsal artery monitoring device in each of the above technical solutions, includes:

[0032] Step 1: Pass the patient's foot through the ankle fixing sleeve into the dorsal foot fixing sleeve;

[0033] Step 2: Press the pressing plate on the patient's dorsal foot and adjust the position of the artery monitor arranged on the pressing plate so that the artery monitor is located above the patient's dorsal artery;

[0034] Wherein, while the pressing plate presses the artery monitor above the dorsalis pedis artery of the patient, the linkage controller synchronously controls the limiting plate to horizontally move in the buffer cavity until the limiting plate fixes the foot receiving seat.

[0035] Advantages of the present invention:

[0036] First, the present invention provides a dorsalis pedis fixing sleeve, which includes a sleeve body, a monitoring and pressing assembly, and a linkage controller. When in use, after the patient's foot penetrates into the sleeve body, the linkage controller fixes the first pressing plate in the monitoring and pressing assembly on the patient's dorsalis pedis while horizontally moving the limiting plate to the lower part of the sole receiving seat through the linkage controller to fix the sole receiving seat, thereby adjusting the position of the artery monitor arranged on the first pressing plate so that the artery monitor is directly above the dorsalis pedis artery of the patient and the artery monitor will not shift.

[0037] Wherein, a sliding piece is arranged at the movable end of the first pressing plate. When in use, the artery detector is arranged on the sliding piece, and the position of the artery detector on the sliding piece can be adjusted, which is simple and convenient to operate.

[0038] Second, the present invention also provides a positioning sleeve, which is arranged on the sliding piece to facilitate the medical staff to adjust the position of the artery monitor; moreover, an anti-slip strip is arranged on the side of the positioning sleeve close to the patient's skin, which can further prevent the movement of the positioning sleeve, thereby further preventing the displacement of the artery monitor arranged in the positioning sleeve.

[0039] Third, the monitoring and pressing assembly provided by the present invention further includes a second pressing plate. After the first pressing plate presses the artery monitor above the dorsalis pedis artery of the patient, the second pressing plate can be pressed downward through an auxiliary presser until the artery detector arranged on the sliding piece is limited in the limiting slideway formed by the double-row limiting strips of the second pressing plate. While playing a limiting role on the artery monitor, the second pressing plate is fixedly pressed above the first sliding plate through the auxiliary presser. Thus, when in use, the artery monitor can be fixed without manual pressing by the medical staff, preventing the displacement of the artery monitor.

[0040] Fourth, on the side of the front sleeve body provided by the present invention that contacts the patient's sole, a sole receiving seat is further arranged, and a pressing spring is arranged below the sole receiving seat; in this way, under the supporting action of the pressing spring, a buffer cavity is formed between the sole receiving seat and the front sleeve body; when the dorsalis pedis artery monitoring is not required, the first pressing plate can be rotated towards the outer side of the patient's dorsalis pedis, and the first pressing plate drives the limiting plate to move towards the outer side of the buffer cavity through the linkage controller, so that the limiting plate moves out from below the sole receiving seat, and then the patient can step on the sole receiving seat to massage the patient's sole.

[0041] During the massage process, the pressing spring under the plantar accommodation seat is compressed. Then, the pressing spring generates a reaction force on the patient's plantar through the plantar accommodation seat, realizing the massage of the patient's plantar.

[0042] V. The linkage controller provided by the present invention includes a pressing plate controller and a limiting plate controller, and the pressing plate controller and the limiting plate controller are rotationally connected through gears. When dorsalis pedis artery monitoring is required, the first pressing plate needs to be pressed on the patient's dorsum pedis. At this time, when the first pressing plate rotates and drives the stretching of the pressing plate controller, the gear arranged at the end of the pressing plate controller also rotates simultaneously. Then, the pressing plate controller drives the stretching of the limiting plate controller and the limiting plate controller rotates in the opposite direction. Then, the limiting plate controller drives the limiting plate located at its end to move downward under the plantar accommodation seat until the limiting plate is located under the plantar accommodation seat, thereby preventing the plantar accommodation seat from moving downward, so as to fix the patient's foot during dorsalis pedis artery monitoring and prevent the patient's foot from moving.

[0043] VI. The present invention is also provided with an ankle fixator on the ankle fixing sleeve. The ankle fixator includes an upper ankle clamping ring, a lower ankle clamping rod, and a clamp. Among them, both the upper ankle clamping ring and the lower ankle clamping rod are connected to the clamp; during use, the upper ankle clamping ring and the lower ankle clamping rod are used to fix both the upper and lower ends of the patient's ankle, preventing the patient's foot from moving and ensuring the normal progress of dorsalis pedis artery monitoring.

[0044] VII. The clamp provided by the present invention includes a folding rod and an opening adjusting rod. During use, medical staff only need to adjust the length of the opening adjusting rod, and both the upper and lower ends of the patient's ankle can be fixed through the upper ankle clamping ring and the lower ankle clamping rod. The structure is simple and the operation is convenient.

[0045] VIII. The present invention uses a positioning sleeve to tightly attach the artery monitor to the patient's skin surface, which can more accurately measure the strength of the patient's dorsalis pedis artery. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] Embodiment 1

[0075] As Figures 1 to 18 shown, this embodiment provides a dorsal artery monitoring device, which includes a dorsal foot fixing sleeve 1 and an ankle fixing sleeve 2.

[0076] As Figure 1 shown, the dorsal foot fixing sleeve 1 includes a sleeve body 11, a monitoring pressing assembly, and a linkage controller 13.

[0077] As Figure 14 shown, the sleeve body 11 is of a stepped structure, including a U-shaped front sleeve body with openings at the front side and the upper end, and a rear sleeve body of a cylindrical structure. Among them, the material of the sleeve body 11 is a rigid material. For example, the material of the sleeve body 11 is hard PVC plastic, PC plastic, etc. The ankle fixing sleeve 2 is connected to the rear sleeve body, and is used to wrap the patient's ankle while preventing the sleeve body 11 from falling off the patient's foot. Specifically, the material of the ankle fixing sleeve 2 is an elastic material. For example, the material of the ankle fixing sleeve 2 is an elastic cloth.

[0078] Among them, the front sleeve body has a sleeve base and a foot receiving seat 12 arranged above the sleeve base. Since a pressing spring 17 is arranged between the two, a buffer cavity 12a is formed between the sleeve base and the foot receiving cavity 12, and a limiting plate 14 is built in the buffer cavity 12a.

[0079] The monitoring pressing assembly includes two pressing plates oppositely arranged on the foot receiving seat 15, and the two pressing plates are respectively a first pressing plate 15 and a second pressing plate 16.

[0080] Specifically, as Figure 4 shown, a sliding piece 15a is arranged on the first pressing plate 15, and the sliding piece 15a is connected to the artery monitor 3;

[0081] In order to further strengthen the fixing effect of the artery monitor, the second pressing plate 16 is arranged on the opposite side of the first pressing plate 15, and the second pressing plate 16 is rotatably connected to the sleeve body 11.

[0082] The second pressing plate 16 is provided with a double-row limiting strip 16a, the center of which forms a limiting slide. When in use, the artery monitor can be pressed by the positioning sleeve 3, so that the artery monitor is closely attached to the patient's skin and is limitedly clamped in the limiting slide. Specifically, Figure 8 As shown, in order to prevent the arterial monitor from sliding, a friction layer 31 is provided on the side of the positioning sleeve 3 that contacts the arterial monitor. When in use, the friction layer 31 can increase the friction between the positioning sleeve 3 and the arterial monitor, further preventing the arterial detector from being displaced.

[0083] When the artery monitor monitors the dorsalis pedis artery, the monitored data is sent to the artery monitoring display 5 for display. It should be noted that the embodiment of the present invention does not improve the artery monitoring display 5.

[0084] like Figure 2 As shown, the linkage controller 13 includes a linkage channel 13a, a pressing plate controller 13b and a limiting plate controller 13c.

[0085] The linkage channel 13a is an L-shaped structure and is fixedly arranged on the side of the sleeve 11. A clearance groove is arranged in the horizontal direction of the linkage channel 13a, and a fixing rod is arranged in the clearance groove; the fixing rod is used to be rotatably connected with the pressing plate controller 13b and the limiting plate controller 13c respectively. Specifically, the pressing plate controller 13b and the limiting plate controller 13c are both telescopic rods.

[0086] like Figure 2 As shown, the upper end of the pressing plate controller 13b is rotatably connected to the first pressing plate 14, and the lower end thereof is sleeved on the fixed rod of the linkage channel 13a and rotatably connected to the fixed rod, and a gear is provided at the lower end of the pressing plate controller 13b for meshing connection with the limit plate controller 13c.

[0087] The upper end of the limit plate controller 13c is provided with a gear so as to engage with the pressing plate controller 13b; similar to the pressing plate controller 13b, the upper end of the limit plate controller 13c is sleeved on the fixed rod in the linkage channel 13a and is rotatably connected to the fixed rod, and the lower end of the limit plate controller 13c is rotatably connected to the limit plate 14.

[0088] The limiting plate 14 is horizontally clamped in the buffer cavity 12a and can slide horizontally in the buffer cavity 12a.

[0089] The working principle of the instep fixing sleeve 1 in the embodiment of the present invention is:

[0090] When it is necessary to monitor the dorsalis pedis artery of a patient, medical staff manually rotate the first pressing plate 15 towards the patient's instep until the first pressing plate 15 presses on the patient's instep, and then adjust the position of the positioning sleeve 3 so that the artery monitor is located between the friction layer 31 and the patient's skin surface, and the artery detector is located above the patient's dorsalis pedis artery;

[0091] While the first pressing plate 15 rotates, the pressing plate controller 13b rotates counterclockwise. Then, the pressing plate controller 13b drives the limit plate controller 13c to rotate clockwise through a gear. Then, the limit plate controller 13c drives the limit plate 14 to move downward to the lower part of the plantar accommodation seat 12, so that the plantar accommodation seat 12 is fixedly arranged in the buffer cavity 12a, and thus the normal monitoring of the patient's dorsalis pedis artery can be ensured.

[0092] When it is not necessary to monitor the dorsalis pedis artery, the first pressing plate 15 can be rotated clockwise away from the patient's instep. During this process, the pressing plate controller 13b rotates clockwise. Then, the pressing plate controller 13b drives the limit plate controller 13c to rotate clockwise through a gear. Then, the limit plate controller 13c drives the limit plate 14 to move outward to the outside of the plantar accommodation seat 12 until the limit plate 14 returns to its initial position. Then, the patient can step on the plantar accommodation seat 12, so that the pressing spring 17 is compressed. Then, the pressing spring 17 provides a reaction force to the plantar accommodation seat 15 for massaging the patient's sole.

[0093] In actual use, the plantar accommodation seat 12 provided in the embodiment of the present invention can specifically be a massage plate. Specifically, massage balls are provided on the side of the plantar accommodation seat 12 in contact with the patient's skin. In this way, when it is not necessary to monitor the dorsalis pedis artery of the patient, the patient can step on the plantar accommodation seat 12, so that the pressing spring is compressed. Then, the pressing spring 17 generates a reaction force on the plantar accommodation seat 12, and thus the massage of the patient's sole is realized.

[0094] It should be noted that, as Figure 17 shown, the initial position of the limit plate 14 provided in the embodiment of the present invention is located in the buffer cavity 12a and on the side of the plantar accommodation seat 15.

[0095] Embodiment 2

[0096] Based on Embodiment 1, the difference from Embodiment 1 is that, as Figure 10 shown, an auxiliary presser 6 is further provided on the side of the second pressing plate 16 provided in the embodiment of the present invention; the auxiliary presser 6 includes an auxiliary pressing rod 61, an adjusting screw 62 and a base 63.

[0097] The base 63 has an L-shaped structure and is fixedly connected to the sleeve body 11. Specifically, the base 63 is also provided with a relief groove in the horizontal direction, and a fixing rod is arranged in the relief groove. The fixing rod is used for rotatably connecting with the auxiliary pressing rod 61. Among them, as Figure 15 and 16 shown, a first rotating connector 64 is arranged at one end of the base 63 away from the second pressing plate 16, and is used for threadedly connecting with the upper end of the adjusting screw 62.

[0098] As Figure 12 shown, the auxiliary pressing rod 61 is a rotating connecting rod, including two connecting rods arranged up and down and rotatably connected; among them, the connecting rod located above is rotatably connected to the second pressing plate 16; the connecting rod located below is provided with a strip-shaped hole 61a, and this connecting rod is sleeved on the fixing rod of the base 63 through the strip-shaped hole 61a.

[0099] Specifically, a second rotating connector 65 is arranged at the end of the connecting rod located below in the auxiliary pressing rod 61.

[0100] During use, the upper end of the adjusting screw 62 is threadedly connected to the first rotating connector 64, and its lower end is threadedly connected to the second rotating connector 65.

[0101] In this way, medical staff can rotate the adjusting screw 62 to make the adjusting screw 62 move upward. At this time, the end of the auxiliary pressing rod 61 is driven by the adjusting screw 62 to tilt upward, so as to realize that the auxiliary pressing rod 61 presses the second pressing plate 14 on the first pressing plate 12. In this way, during the process of monitoring the dorsalis pedis artery of the patient, it is not necessary for medical staff to manually press the artery monitor 3, and the fixation of the artery monitor 3 can be realized.

[0102] Embodiment 3

[0103] Based on Embodiment 1, what is different from both Embodiment 1 and Embodiment 2 is that, in order to further prevent the patient's foot from moving, as Figure 1 and 5 shown, the ankle fixator 4 is also provided on the ankle fixing sleeve 2 provided by the embodiment of the present invention.

[0104] Specifically, the ankle fixator 4 includes an upper ankle clamping ring 41, a lower ankle clamping rod 42 and a clamp 43.

[0105] The upper ankle clamping ring 41 includes a semi-circular clamping ring and a connecting rod connected to the semi-circular clamping ring; during use, the semi-circular clamping ring contacts the patient's skin, and the end with the connecting rod passes through the upper end of the ankle fixing sleeve 2 and is rotatably connected to the clamp 43.

[0106] In actual use, an upper ankle clamping member 41 and a lower ankle clamping rod 43 are symmetrically arranged on both sides of the patient's ankle respectively.

[0107] As shown Figure 5 in the figure, the clamp 42 includes a folding rod 42a and an opening adjusting rod 42b.

[0108] The folding rod 42a has a double-link structure; specifically, the folding rod 43a includes two symmetrically arranged and rotatably connected folding units; the two folding units are rod-shaped structures, and the two folding units are respectively rotatably connected to the upper ankle clamping clips 41 located on both sides of the patient's ankle, thereby forming an opening. Among them, as Figure 6 shown in the figure, the folding unit is provided with a connection port for connecting with the opening adjusting rod 42b.

[0109] The upper ends of the lower ankle clamping rods 42 located on both sides of the patient's ankle are respectively and correspondingly rotatably connected to the two folding units of the folding rod 43a.

[0110] The opening adjusting rod 43b includes a threaded sleeve and a threaded rod; the threaded rod is in threaded cooperation with the threaded sleeve.

[0111] Specifically, after the threaded sleeve and the threaded rod respectively pass through the two folding units of the folding rod 43a, the two are threadedly connected; in this way, the medical staff only need to rotate the threaded rod to adjust the overall length of the opening adjusting rod 43b, and then adjust the opening size of the folding rod 42a. Among them, as Figure 6 shown in the figure, the threaded sleeve and the threaded rod are both provided as stepped rod-shaped structures, and the stepped parts of the threaded sleeve and the threaded rod are respectively arranged in the connection ports of the folding rod 42a, and the diameters of the stepped parts of the threaded sleeve and the threaded rod are both larger than the diameter of the connection port, so as to limit the folding rod 42a on the opening adjusting rod 42b and prevent the folding rod 42a from disengaging from the opening adjusting rod 42b.

[0112] The lower ankle clamping rod 43 is a rotating rod, one end of which is rotatably connected to the opening adjusting rod 42b, and the other end is fixedly connected to the lower end of the ankle fixing sleeve 2. During use, in order to prevent the multi-link movement of the lower ankle clamping rod 43 and the upper ankle clamping ring 41 from jamming, as Figure 6 shown in the figure, the folding rod 42a is provided with a through hole, and a buffer spring 44 is provided on the opening adjusting rod 42b. In this way, when the threaded rod in the opening adjusting rod 42b rotates, it will not press the lower fixing rod 42 against the inner wall of the through hole of the upper ankle clamping ring 41, ensuring that the lower ankle clamping rod 43 fixes the lower part of the patient's ankle under the action of the opening adjusting rod 42b.

[0113] The working principle of the clamp 43 is as follows: Rotate the threaded rod in the opening adjusting rod 42b towards the inside of the threaded sleeve, so that the angle between the two folding units of the folding rod 42a becomes smaller. Then, the folding rod 42a drives the upper ankle clamping ring 41 to tightly contact above the patient's ankle. At the same time, the lower ankle clamping rod 43 is driven by the opening adjusting rod 42b to squeeze below the patient's ankle. At this time, the lower ankle clamping rod 43 tightly contacts below the patient's ankle. Thus, both above and below the patient's ankle are fixed, preventing the patient's ankle from moving.

[0114] In practical applications, the upper ankle clamping ring 41 includes two symmetrically arranged semi-circular clamping rings, and the two semi-circular clamping rings are respectively connected to the two ends of the folding rod 42a correspondingly. Similarly, the lower ankle clamping rod 43 includes two rotating rods symmetrically arranged on both sides of the patient's ankle, and the upper ends of the two rotating rods are both connected to the opening adjusting rod 42b, and their lower ends are both connected to the ankle fixing sleeve 2.

[0115] Application case:

[0116] Wu, 60 years old, for screening of lower limb arterial ischemic diseases, dorsal artery of foot monitoring is required.

[0117] Step 1: The medical staff rotates the threaded rod in the opening adjusting rod 42b towards the outside of the threaded sleeve, so that the opening of the ankle fixing sleeve 2 expands, so that the patient's foot can pass through the ankle fixing sleeve 2 and enter the dorsal foot fixing sleeve 1.

[0118] Step 2: The medical staff rotates the threaded rod in the opening adjusting rod 42b towards the inside of the threaded sleeve. At this time, the overall length of the opening adjusting rod 42b shortens, so that the upper ankle clamping ring 41 moves towards the patient's ankle until the upper ankle clamping ring 41 tightly fixes above the patient's ankle.

[0119] At the same time, the lower ankle clamping rod 43 moves towards the patient's ankle under the action of the opening adjusting rod 42b until the patient's ankle part is tightly fixed.

[0120] Step 3: The medical staff manually presses the first pressing plate 15 on the patient's dorsal foot. At this time, while the first pressing plate 15 drives the pressing plate controller 13b to be stretched and rotates counterclockwise, the pressing plate controller 13b drives the gear on the limit plate controller 13c to rotate clockwise through the gear. Then, while the limit plate controller 13c is stretched, it drives the limit plate 14 to move into the buffer cavity 12a until the limit plate 14 is located below the sole receiving seat 12, playing a supporting role for the sole receiving seat 12.

[0121] Step 4: Adjust the position of the positioning sleeve 3 on the sliding piece 12a so that the dorsal artery detector is pressed by the positioning sleeve 3 above the patient's dorsal artery.

[0122] Step Five: The medical staff rotates the second pressing plate 16 clockwise until the second pressing plate 16 presses against the upper side of the first pressing plate 15, thereby clamping the artery monitor in the limiting cavity at the center of the double-row limiting strips 16a;

[0123] In this step, the auxiliary pressing rod 61 rotates as the second pressing plate 16 rotates. Then, the medical staff rotates the adjusting screw 62, causing the whole adjusting screw 62 to move upward. Thereby, the adjusting screw 62 drives the end of the auxiliary pressing rod 61 to tilt upward. At this time, under the action of the auxiliary pressing rod 61, the second pressing plate 16 is tightly pressed against the first pressing plate 15. In this way, the dorsalis pedis artery monitoring can be achieved without manual pressing by the medical staff.

[0124] Step Six: Start the dorsalis pedis artery monitoring;

[0125] Step Seven: After the monitoring is completed, the medical staff rotates the adjusting screw 62 in the reverse direction, causing the adjusting screw 62 to move downward. Thereby, the adjusting screw 62 drives the end of the auxiliary pressing rod 61 to rotate downward. Then, the auxiliary pressing rod 61 drives the second pressing plate 16 to rotate in the reverse direction, causing the second pressing plate 16 to move away from the first pressing plate 15, so as to take out the artery monitor;

[0126] Then, the medical staff rotates the first pressing plate 15 clockwise. At this time, the length of the pressing plate controller 13b becomes shorter and rotates clockwise. Thereby, the pressing plate controller 13b drives the gear on the limiting plate controller 13c to rotate counterclockwise. Then, the limiting plate controller 13c drives the limiting plate 14 to move outward to the outside of the buffer cavity 11a of the sleeve body 11 until it moves away from below the sole accommodating seat 12, so that the patient's foot can step on the sole accommodating seat 12 for sole massage and take out the artery monitor.

[0127] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
