Description

Technical Field

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

[0002] Under normal circumstances, the dorsalis pedis artery should beat with the heartbeat. Since the dorsalis pedis artery is located at a relatively shallow position on the human body surface, it is easy to touch. The normal pulsation of the dorsalis pedis artery indicates that the human body has sufficient blood, the heart beats strongly, the heart function is normal, and the artery is not narrowed or blocked. If the arterial pulsation cannot be touched, it means that the condition is very serious, such as heart failure, insufficient blood volume, etc. In addition, if there is atherosclerosis, the dorsalis pedis artery pulsation cannot be touched. 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, it is necessary to accurately and objectively monitor the strength of the vascular pulsation pressure by reflecting the strength of the dorsalis pedis artery fluctuation. In short, by touching the dorsalis pedis artery pulsation, diseases can be known early, and early intervention and treatment of diseases are extremely important. At present, in order to facilitate the detection of the dorsalis pedis artery, some straps are usually used to directly fix the pulse sensor to the dorsalis pedis artery for detection. This method is not reliable and is prone to displacement, especially during patient activities, which makes it difficult to carry out long-term real-time monitoring.

[0003] The patent with publication number CN113940639A discloses a dorsalis pedis artery monitoring device, comprising: a sock having a heel portion and a strap portion connected to the front end of the heel portion; a pulse sensor is arranged on the strap portion; a monitor is detachably connected to the sock and connected to the pulse sensor through a connecting line; when the sock is put on the patient's foot, the strap portion is suitable for being fastened to the patient's instep so that the pulse sensor is attached to the dorsalis pedis artery.

[0004] In the above technical solution, the pulse sensor is ensured not to shift by placing the first suction cup and the second suction cup on both sides of the pulse sensor and adsorbing the first suction cup and the second suction cup on the body surface on both sides of the dorsalis pedis artery. However, in actual application, the patient's skin surface has oil and sweat, and the suction force of the first suction cup and the second suction cup is not strong. If the patient's foot moves during the monitoring process, the pulse sensor cannot be ensured not to shift, and the use effect is poor. Summary of the invention

[0018] Beneficial effects of the present invention: 1. The present invention provides a dorsum fixing sleeve, which includes a sleeve body, a monitoring and pressing assembly, and a linkage controller. When the patient's foot is inserted into the sleeve body, the linkage controller is used to fix the first pressing plate in the monitoring and pressing assembly on the dorsum of the patient's foot, and the linkage controller is used to horizontally move the limit plate to the bottom of the plantar accommodation seat so as to fix the plantar accommodation seat, and then adjust the position of the artery monitor set on the first pressing plate so as to place the artery monitor directly above the dorsalis pedis artery of the patient, and the artery monitor will not be displaced; A sliding sheet is provided at the movable end of the first pressing plate. When in use, the artery detector is arranged on the sliding sheet. The position of the artery detector on the sliding sheet can be adjusted, and the operation is simple and convenient.

[0019] Second, the present invention also provides a positioning sleeve, which is arranged on the sliding sheet so that medical personnel can adjust the position of the arterial monitor; in addition, an anti-slip strip is provided on the side of the positioning sleeve close to the patient's skin, which can further prevent the positioning sleeve from moving, thereby further preventing the arterial monitor set in the positioning sleeve from being displaced.

[0020] 3. The monitoring and pressing assembly provided by the present invention also includes a second pressing plate. After the first pressing plate presses the arterial monitor above the patient's dorsalis pedis artery, the second pressing plate can be pressed downward by an auxiliary presser until the arterial detector on the sliding sheet is limited in the limiting slide formed by the double-row limiting strips of the second pressing plate. While limiting the arterial monitor, the second pressing plate is fixed and pressed against the top of the first sliding plate by the auxiliary presser. Therefore, when in use, the arterial monitor can be fixed without the medical staff manually pressing the arterial detector to prevent the arterial monitor from being displaced.

[0021] Fourth, the front sleeve provided by the present invention is also provided with a sole accommodating seat on the side in contact with the sole of the patient's foot, and a pressing spring is arranged below the sole accommodating seat; in this way, under the support of the pressing spring, a buffer cavity is formed between the sole accommodating seat and the front sleeve; when the dorsalis pedis artery monitoring is not required, the first pressing plate can be rotated toward the outside of the dorsum of the patient's foot, and the first pressing plate drives the limiting plate to move toward the outside of the buffer cavity through the linkage controller, so that the limiting plate moves out from below the sole accommodating seat, and then the patient can massage the sole of the patient's foot by stepping on the sole accommodating seat; During the massage process, the pressing spring under the sole receiving seat is compressed, and then the pressing spring generates a reaction force on the sole of the patient's foot through the sole receiving seat, thereby massaging the sole of the patient's foot.

[0022] 5. The linkage controller provided by the present invention includes a pressing plate controller and a limit plate controller, and the pressing plate controller and the limit plate controller are rotatably connected through gears. When dorsalis pedis artery monitoring is required, the first pressing plate needs to be pressed on the patient's instep. At this time, the first pressing plate rotates to drive the pressing plate controller to be stretched, and the gear set at the end of the pressing plate controller also rotates at the same time, and then the pressing plate controller drives the limit plate controller to stretch and the limit plate controller rotates in the opposite direction, and then the limit plate controller drives the limit plate at its end to move under the plantar accommodating seat until the limit plate is located under the plantar accommodating seat, thereby preventing the plantar accommodating seat from moving downward, so that when the dorsalis pedis artery monitoring is performed, the patient's foot can be fixed to prevent the patient's foot from moving.

[0023] 6. The present invention also provides an ankle fixer on the ankle fixation sleeve, and the ankle fixator includes an upper ankle clamping ring, a lower ankle clamping rod and a clamp, wherein the upper ankle clamping ring and the lower ankle clamping rod are both connected to the clamp; when in use, the upper ankle clamping ring and the lower ankle clamping rod are used to fix the upper and lower ends of the patient's ankle to prevent the patient's foot from moving, thereby ensuring the normal monitoring of the dorsalis pedis artery.

[0024] 7. The clamp provided by the present invention includes a folding rod and an opening adjustment rod. When in use, medical staff only need to adjust the length of the opening adjustment rod to fix the upper and lower ends of the patient's ankle through the upper ankle clamping ring and the lower ankle clamping rod. The structure is simple and the operation is convenient.

[0025] 8. The present invention uses a positioning sleeve to tightly attach the artery monitor to the patient's skin surface, so as to more accurately measure the strength of the patient's dorsalis pedis artery. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, features limited to "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example 1 like Figures 1 to 18 As shown, this embodiment provides a dorsalis pedis artery monitoring device, including a dorsalis pedis fixing sleeve 1 and an ankle fixing sleeve 2.

[0033] like Figure 1 As shown, the dorsum of the foot fixing sleeve 1 includes a sleeve body 11 , a monitoring and pressing component and a linkage controller 13 .

[0034] like Fig.14As shown, the sleeve 11 is a stepped structure, including a U-shaped front sleeve with an open front side and an upper end, and a rear sleeve with a cylindrical structure. The sleeve 11 is made of a hard material. For example, the sleeve 11 is made of hard PVC plastic, PC plastic, etc. The ankle fixing sleeve 2 is connected to the rear sleeve to wrap the patient's ankle while preventing the sleeve 11 from falling off the patient's foot. Specifically, the ankle fixing sleeve 2 is made of an elastic material. For example, the ankle fixing sleeve 2 is made of elastic cloth.

[0035] The front housing has a housing seat and a foot receiving seat 12 disposed above the housing seat. A compression spring 17 is disposed between the two, so that a buffer cavity 12a is formed between the housing seat and the foot receiving cavity 12, and a limiting plate 14 is built into the buffer cavity 12a.

[0036] The monitoring pressing assembly includes two pressing plates disposed opposite to each other on the foot receiving seat 15 , and the two pressing plates are respectively a first pressing plate 15 and a second pressing plate 16 .

[0037] Specifically, Figure 4 As shown, a sliding sheet 15a is provided on the first pressing plate 15, and the sliding sheet 15a is connected to the artery monitor 3; In order to further enhance the fixing effect of the arterial monitor, the second pressing plate 16 is disposed on the opposite side of the first pressing plate 15 , and the second pressing plate 16 is rotatably connected to the sleeve body 11 .

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] The limiting plate 14 is horizontally clamped in the buffer cavity 12a and can slide horizontally in the buffer cavity 12a.

[0045] The working principle of the instep fixing sleeve 1 in the embodiment of the present invention is: When the dorsalis pedis artery of the patient needs to be monitored, the medical staff manually rotates the first pressing plate 15 toward the patient's instep until the first pressing plate 15 is pressed on the patient's instep, and then adjusts 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; While the first pressing plate 15 rotates, the pressing plate controller 13b rotates counterclockwise, and then the pressing plate controller 13b drives the limit plate controller 13c to rotate clockwise through the gears, and then the limit plate controller 13c drives the limit plate 14 to move downward to the plantar accommodating seat 12, so that the plantar accommodating seat 12 is fixedly disposed in the buffer cavity 12a, thereby ensuring the normal monitoring of the patient's dorsalis pedis artery.

[0046] When dorsalis pedis artery monitoring is not needed, 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, and then the pressing plate controller 13b drives the limit plate controller 13c to rotate clockwise through gears, and then the limit plate controller 13c drives the limit plate 14 to move toward the outside of the plantar accommodating seat 12 until the limit plate 14 returns to the initial position, and then the patient can step on the plantar accommodating seat 12 to compress the pressing spring 17, and then the pressing spring 17 provides a reaction force to the plantar accommodating seat 15 to massage the patient's foot.

[0047] In actual use, the foot accommodating seat 12 provided in the embodiment of the present invention can be a massage board. Specifically, a massage ball is provided on the side of the foot accommodating seat 12 that contacts the patient's skin, so that when the patient's dorsalis pedis artery does not need to be monitored, the patient can pass through the foot accommodating seat 12, so that the foot spring is compressed, and then the spring 17 is pressed to generate a reaction force on the foot accommodating seat 12, thereby achieving foot massage for the patient.

[0048] It should be noted that if Fig.17 As shown, the initial position of the limiting plate 14 provided in the embodiment of the present invention is located in the buffer cavity 12 a and on the side of the sole receiving seat 15 .

[0049] Example 2 Based on Example 1, different from Example 1, Fig.10 As 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 .

[0050] The base 63 is an L-shaped structure, and is fixedly connected to the sleeve body 11. Specifically, the base 63 is also provided with a clearance groove in the horizontal direction, and a fixing rod is provided in the clearance groove, and the fixing rod is used to be rotatably connected to the auxiliary pressing rod 61. Fig.15 and 16 As shown, a first rotating connecting member 64 is provided at one end of the base 63 away from the second pressing plate 16 for being threadedly connected to the upper end of the adjusting screw 62 .

[0051] like Fig.12 As shown, the auxiliary pressing rod 61 is a rotating connecting rod, including two connecting rods arranged up and down and rotatably connected; wherein, the connecting rod located at the upper end is rotatably connected to the second pressing plate 16; the connecting rod located at the lower end is provided with a strip hole 61a, and the connecting rod is sleeved on the fixed rod of the base 63 through the strip hole 61a.

[0052] Specifically, a second rotating connecting member 65 is provided at the end of the connecting rod located at the bottom of the auxiliary pressing rod 61 .

[0053] When in use, the upper end of the adjusting screw 62 is threadedly connected to the first rotating connection member 64 , and the lower end thereof is threadedly connected to the second rotating connection member 65 .

[0054] In this way, the medical staff can rotate the adjusting screw 62 to move the adjusting screw 62 upward. At this time, the end of the auxiliary pressing rod 61 is tilted upward under the drive of the adjusting screw 62, so that the auxiliary pressing rod 61 presses the second pressing plate 14 onto the first pressing plate 12. In this way, during the process of monitoring the dorsalis pedis artery of the patient, the medical staff can fix the artery monitor 3 without manually pressing the artery monitor 3.

[0055] Example 3 Based on embodiment 1, different from embodiments 1 and 2, in order to further prevent the patient's foot from moving, as shown in FIG. Figure 1 and 5 As shown, the ankle fixing sleeve 2 provided in the embodiment of the present invention is also provided with an ankle fixing device 4.

[0056] Specifically, the ankle fixator 4 includes an upper ankle clamping ring 41 , a lower ankle clamping rod 42 and a clamp 43 .

[0057] The upper ankle clamping ring 41 includes a semicircular ring and a connecting rod connected to the semicircular ring; when in use, the semicircular ring contacts the patient's skin, and one end of the connecting rod passes through the upper end of the ankle fixing sleeve 2 and is rotatably connected to the clamp 43.

[0058] In actual use, an upper ankle clamping fixture 41 and a lower ankle clamping rod 43 are symmetrically arranged on both sides of the patient's ankle.

[0059] like Figure 5 As shown, the clamp 42 includes a folding lever 42a and an opening adjustment lever 42b.

[0060] The folding rod 42a is 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 rotatably connected to the upper ankle clamping clamps 41 located on both sides of the patient's ankle, thereby forming an opening. Figure 6 As shown, a connection port is provided on the folding unit so as to be connected with the opening adjustment rod 42b.

[0061] The upper ends of the lower ankle clamping rods 42 located on both sides of the patient's ankles respectively correspond to the two units of the folding rod 43a and are rotatably connected.

[0062] The opening adjustment rod 43b includes a threaded sleeve and a threaded rod; the threaded rod is threadably matched with the threaded sleeve.

[0063] Specifically, after the threaded sleeve and the threaded rod pass through the two folding units of the folding rod 43a respectively, the two are threadedly connected; in this way, the medical staff only needs to rotate the threaded rod to adjust the overall length of the opening adjustment rod 43b, thereby adjusting the opening size of the folding rod 42a. Figure 6 As shown, the threaded sleeve and the threaded rod are both configured as a stepped rod structure, and the stepped portion of the threaded sleeve and the stepped portion of the threaded rod are respectively arranged in the connecting port of the folding rod 42a, and the stepped portion of the threaded sleeve and the stepped portion of the threaded rod have a diameter larger than the connecting port diameter, so as to limit the folding rod 42a on the opening adjustment rod 42b to prevent the folding rod 42a from falling off the opening adjustment rod 42b.

[0064] The lower ankle clamping rod 43 is a rotating rod, one end of which is rotatably connected to the opening adjustment rod 42b, and the other end is fixedly connected to the lower end of the ankle fixing sleeve 2. When in use, in order to prevent the lower ankle clamping rod 43 and the upper ankle clamping clamp ring 41 from getting stuck during the multi-link movement, Figure 6 As shown, the folding rod 42a is provided with a through hole, and a buffer spring 44 is provided on the opening adjustment rod 42b, so that the threaded rod in the opening adjustment rod 42b will not press the lower fixing rod 42 on the inner wall of the through hole of the upper ankle clamping ring 41 during the rotation process, thereby ensuring that the lower ankle clamping rod 43 fixes the lower part of the patient's ankle under the action of the opening adjustment rod 42b.

[0065] The working principle of the clamp 43 is as follows: the threaded rod in the opening adjustment rod 42b is rotated toward the inside of the threaded sleeve, so that the angle between the two folding units of the folding rod 42a becomes smaller, and then the folding rod 42a drives the upper ankle clamping ring 41 to tightly contact the upper part of the patient's ankle; at the same time, the lower ankle clamping rod 43, driven by the opening adjustment rod 42b, squeezes the lower part of the patient's ankle. At this time, the lower ankle clamping rod 43 is tightly contacted with the lower part of the patient's ankle, and then the upper and lower parts of the patient's ankle are fixed, thereby preventing the patient's ankle from moving.

[0066] In actual application, the upper ankle clamping ring 41 includes two symmetrically arranged semicircular clamping rings, and the two semicircular clamping rings are respectively connected to the two ends of the folding rod 42a. 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 connected to the opening adjustment rod 42b, and the lower ends are connected to the ankle fixing sleeve 2.

[0067] Application examples: Mr. Wu, 60 years old, is undergoing screening for lower extremity arterial ischemic disease and requires dorsalis pedis artery monitoring.

[0068] Step 1: The medical staff rotates the threaded rod in the opening adjustment rod 42b toward the outside of the threaded sleeve to expand the opening of the ankle fixing sleeve 2 so that the patient's foot can pass through the ankle fixing sleeve 2 and then enter the instep fixing sleeve 1; Step 2: The medical staff rotates the threaded rod in the opening adjustment rod 42b toward the inside of the threaded sleeve, and the overall length of the opening adjustment rod 42b is shortened, so that the upper ankle clamping ring 41 moves toward the patient's ankle until the upper ankle clamping ring 41 tightly fixes the upper part of the patient's ankle; At the same time, the lower ankle clamping rod 43 moves toward the patient's ankle under the action of the opening adjustment rod 42b until the patient's ankle is tightly fixed; Step 3: The medical staff manually presses the first pressing plate 15 on the dorsum of the patient's foot. At this time, the first pressing plate 15 drives the pressing plate controller 13b to be stretched and rotate counterclockwise, and then the pressing plate controller 13b drives the gear on the limit plate controller 13c to rotate clockwise through the gear, and then the limit plate controller 13c is stretched and drives the limit plate 14 to move into the buffer cavity 12a, until the limit plate 14 is located below the sole accommodating seat 12, so as to support the sole accommodating seat 12; Step 4: Adjust the position of the positioning sleeve 3 on the sliding sheet 12a so that the dorsalis pedis artery detector is pressed above the dorsalis pedis artery of the patient by the positioning sleeve 3; Step 5: The medical staff rotates the second pressing plate 16 clockwise until the second pressing plate 16 is pressed against the top 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; In this step, the auxiliary pressing rod 61 rotates with the rotation of the second pressing plate 16, and then the medical staff rotates the adjusting screw 62, so that the adjusting screw 62 moves upward as a whole, and then the adjusting screw 62 drives the end of the auxiliary pressing rod 61 to tilt upward. At this time, the second pressing plate 16 is tightly pressed against the first pressing plate 15 under the action of the auxiliary pressing rod 61. In this way, the dorsalis pedis artery monitoring can be achieved without manual pressing by the medical staff.

[0069] Step 6: Start dorsalis pedis artery monitoring; Step 7: After the monitoring is completed, the medical staff rotates the adjusting screw 62 in the opposite direction to move the adjusting screw 62 downward, and then the adjusting screw 62 drives the end of the auxiliary pressing rod 61 to rotate downward, and then the auxiliary pressing rod 61 drives the second pressing plate 16 to rotate in the opposite direction, so that the second pressing plate 16 is away from the first pressing plate 15, so as to take out the artery monitor; Then, the medical staff rotates the first pressing plate 15 clockwise, and the pressing plate controller 13b becomes shorter and rotates clockwise at the same time, and then the pressing plate controller 13b drives the gear on the limit plate controller 13c to rotate counterclockwise, and then the limit plate controller 13c drives the limit plate 14 to move to the outside of the buffer cavity 11a of the sleeve 11 until it leaves the bottom of the plantar accommodating seat 12, so that the patient's foot can step on the plantar accommodating seat 12 to perform a foot massage and take out the arterial monitor.
