Description

Technical Field

[0001] The invention relates to the technical field of medical care products, and in particular to a foot positioning device for lower limb image scanning. Background Art

[0002] In major hospitals, patients lie flat on the CT scanning bed in the imaging department. When doctors perform CT scans on patients' lower limbs, they usually require the patients to point their toes upward and place their lower limbs as vertically as possible, rather than leaning forward, backward or sideways. The purpose is to effectively control the patient's foot CT scanning posture and the length range of the patient's foot CT scanning, so as to reduce the cost of CT scanning.

[0003] For some patients, especially children who like to move their feet during the examination and patients whose feet habitually lean forward, backward or sideways, the posture of their feet is difficult to control, so the CT examination of the entire lower limbs including the feet will be particularly difficult.

[0004] In this regard, the inventor of this patent combined clinical experience, thought about the problems encountered in clinical work, read a large amount of scientific research materials and literature, and through retrieval and novelty search, gradually conceived and designed this application to solve related technical problems. Summary of the invention

[0013] The left sliding block can slide up and down and be fixed in the left sliding groove A, and the right sliding block can slide up and down and be fixed in the right sliding groove A.

[0014] According to an embodiment of the present invention, the left slider and the right slider are both formed into long strip structures, and the left and right ends of the elastic band are correspondingly connected between the lower right portion of the left slider and the lower left portion of the right slider.

[0015] According to one embodiment of the present invention, it also includes a left connecting block and a right connecting block arranged along the front-back direction and a gripping rod arranged along the left-right direction;

[0016] The upper end surface of the foot support block is provided with a left slide groove B adapted to be fixed to the left connecting block along the vertical direction at the rear side of the left slide groove A, and a right slide groove B adapted to be fixed to the right connecting block is provided along the vertical direction at the rear side of the right slide groove A;

[0017] A left avoidance groove connected to the foot fixing groove is vertically formed at the rear end of the left slide groove B; a right avoidance groove connected to the foot fixing groove is vertically formed at the rear end of the right slide groove B;

[0018] The left end of the grip rod extends into the left avoidance groove and is connected to the rear of the left connecting block; the right end of the grip rod extends into the right avoidance groove and is connected to the rear of the right connecting block, so that its height is higher than that of the elastic band.

[0019] According to an embodiment of the present invention, a plurality of anti-slip convex strips are evenly arranged on the outer wall of the grip rod along the left-right direction.

[0020] According to one embodiment of the present invention, it also includes a support pad for supporting the patient's lower limbs and feet;

[0021] The support pad is removably stacked on the bottom of the lower limb fastening groove, and its front end extends into the foot fastening groove.

[0022] According to an embodiment of the present invention, the support pad is made of soft rubber material, and a plurality of massage convex points are evenly protruded upward on the upper end surface of the support pad.

[0023] According to an embodiment of the present invention, the front middle portion of the support pad protrudes upward in the left-right direction to form an ankle supporting portion for supporting the ankle.

[0024] According to one embodiment of the present invention, the left end surface of the lower limb lifting and positioning piece is provided with a male Velcro, and the right end surface is provided with a female Velcro;

[0025] When the two lower limb image scanning foot positioning devices are arranged closely together so that the female Velcro and the male Velcro are adhered to each other in relative positions, the two lower limb image scanning foot positioning devices are fixed together as a whole.

[0026] According to one embodiment of the present invention, the bottom surface of the lower limb supporting positioning member is formed into a serrated structure to form an anti-slip resting surface.

[0027] The beneficial effects of the present invention are:

[0028] First, the foot positioning device for lower limb imaging scanning provided by the present application is placed on a CT scanning bed during specific implementation so that the patient lies flat on the CT scanning bed, and the lower limbs and feet that need to be scanned by the present application are placed in the lower limb clamping groove and the foot clamping groove respectively, so that the soles of the patient's feet are in close contact with the front inner end surfaces of the foot clamping grooves as much as possible. After the lower limbs and feet of the patient are stably supported, the instep of the patient's foot is clamped by the instep support fixture so that the toes of the patient's feet are kept in an upward posture as much as possible. Then, the CT machine can be started and the lower limbs and feet of the patient that need to be examined are sent into the CT machine for CT examination. In this way, the present application can be easily used.

[0029] Second, by providing the lower limb lifting and positioning piece, the patient's lower limbs and feet that need to undergo CT scanning can be placed in the lower limb clamping groove and the foot clamping groove to be limited, so that they are not easy to shake left and right. By providing the instep support piece, the patient's instep is supported so that the toes of the patient's foot can be kept in an upward posture as much as possible. In this way, the patient's foot CT examination scanning posture and the patient's foot CT examination scanning length range can be effectively controlled, so as to greatly reduce the CT examination scanning cost and greatly reduce the workload of medical staff, so that the CT examination of the patient's lower limbs and feet can become easier and more time-saving, and the instep support piece provided can slide upward to facilitate the removal of the patient's foot.

[0030] Third, before using the present application, the instep support piece can be detached from the lower limb lifting and positioning piece, so that it is convenient for the patient's foot to be inserted into the foot fixing groove, and then the left slider can be inserted into the left slide groove A, and the right slider can be inserted into the right slide groove A. When they fall naturally, the elastic band can be fixed to the instep of the patient's foot, so that the toes of the patient's foot can be kept as upward as possible, so that the use of the present application can indeed facilitate CT examination of the patient's lower limbs and feet.

[0031] Fourthly, through the optimized design of the structure, the height of the grip rod is higher than the height of the elastic band. When the elastic band is used to secure the patient's instep, the grip rod will not press on the patient's ankle and other parts of the lower limbs due to its higher height, so that the application is reliable to use. When the medical staff lifts the grip rod upwards, they can simultaneously extract the left connecting block, the right connecting block, the left slider, the right slider and the elastic band, so that the instep supporting piece can be quickly removed, and the patient's lower limbs and feet can be quickly removed from the lower limb securing groove and the foot securing groove of the lower limb lifting positioning piece, making the application more convenient to use.

[0032] Fifth, when the two lower limb image scanning foot positioning devices are arranged closely together so that the female Velcro and the male Velcro are adhered to each other in relative position, the two lower limb image scanning foot positioning devices are fixed as one. In this way, when a CT scan is required on both lower limbs and feet of the patient, two of the present applications can be used and connected together to fix the patient's lower limbs and feet, making the present application more flexible to use.

[0033] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] The following describes in detail the lower limb image scanning foot positioning device 1000 according to an embodiment of the present invention with reference to the accompanying drawings.

[0074] Reference Figures 1 to 5 As shown, the lower limb imaging scanning foot positioning device 1000 provided according to an embodiment of the present invention comprises a lower limb lifting positioning member 10 and a foot back-supporting member 20 for supporting the patient's foot back;

[0075] Wherein, the lower limb lifting positioning member 10 and the instep supporting member 20 are both made of non-metallic materials;

[0076] Furthermore, the lower limb lifting positioning member 10 comprises a foot support block 101 and a lower limb support block 102 connected to the rear lower part of the foot support block 101, a foot fastening groove 1011 penetrating through the rear end surface of the foot support block 101 is downwardly opened in the middle of the upper end surface, and a lower limb fastening groove 1021 is opened along the front-to-back direction on the upper end surface of the lower limb support block 102, and the front end of the lower limb fastening groove 1021 is connected to the lower end of the foot fastening groove 1011;

[0077] The instep support member 20 is fixed in the rear notch of the foot fixing groove 1011 so as to slide up and down, and a foot accommodating space is defined between the front end surface of the instep support member 20 and the front inner wall of the foot fixing groove 1011 .

[0078] Based on the above, it is clear that when the present application is implemented, it is mainly used as a foot positioning device 1000 for lower limb image scanning.

[0079] Specifically, when applying the present application, the present application is placed on a CT scanning bed so that the patient lies flat on the CT scanning bed, and the lower limbs and feet that need to be scanned are placed in the lower limb clamping groove 1021 and the foot clamping groove 1011 accordingly, so that the soles of the patient's feet are as closely fitted as possible with the front inner end surfaces of the foot clamping grooves 1011. After the patient's lower limbs and feet are stably supported, the patient's instep is secured by the instep support fixture 20 so that the toes of the patient's feet are kept as upward as possible. Then, the CT machine can be started and the patient's lower limbs and feet that need to be examined are sent into the CT machine for CT examination. In this way, the present application can be easily used.

[0080] Obviously, the use of the above-mentioned application will have the following technical effects.

[0081] By providing the lower limb lifting positioning member 10, the patient's lower limbs and feet that need to undergo CT scanning can be better placed in the lower limb fixing groove 1021 and the foot fixing groove 1011 to be limited and not easily shaken left and right. By providing the instep support member 20, the patient's instep is supported so that the toes of the patient's foot can be kept in an upward posture as much as possible. In this way, the patient's foot CT examination scanning posture and the patient's foot CT examination scanning length range can be effectively controlled, so as to greatly reduce the CT examination scanning cost and greatly reduce the workload of medical staff, so that the CT examination of the patient's lower limbs and feet can become easier and more time-saving, and the instep support member 20 can slide upward to facilitate the removal of the patient's foot.

[0082] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good practical effects.

[0083] Further, in a specific implementation, according to an embodiment of the present invention, the instep support member 20 includes a left slider 201, a right slider 202, and an elastic band 203 connected between the left slider 201 and the right slider 202;

[0084] The upper end surface of the foot support block 101 is provided with a left slide groove A1012 connected to the foot fastening groove 1011 along the vertical direction on the left side of the rear notch of the foot fastening groove 1011, and a right slide groove A1013 connected to the foot fastening groove 1011 is provided on the right side of the rear notch of the foot fastening groove 1011 along the vertical direction;

[0085] Based on this, in the present application, the left slider 201 can slide up and down and be fixed in the left slide groove A1012, and the right slider 202 can slide up and down and be fixed in the right slide groove A1013.

[0086] Therefore, it can be clearly seen that before using the present application, the instep support piece 20 can be detached from the lower limb lifting and positioning piece 10, so that it is convenient for the patient's foot to be inserted into the foot fixing groove 1011, and then the left slider 201 can be inserted into the left slide groove A1012, and the right slider 202 can be inserted into the right slide groove A1013. When they fall naturally, the elastic band 203 can be fixed to the instep of the patient's foot, so that the toes of the patient's foot can be kept as upward as possible and fixed, so that the use of the present application can indeed facilitate CT examination of the patient's lower limbs and feet.

[0087] Furthermore, in a specific implementation, according to an embodiment of the present invention, the left slider 201 and the right slider 202 are both formed into a long strip structure, and the left and right ends of the elastic band 203 are correspondingly connected between the lower right part of the left slider 201 and the lower left part of the right slider 202.

[0088] From this, it can be clearly seen that the reason why the left and right ends of the elastic band 203 are correspondingly connected between the right lower part of the left slider 201 and the left lower part of the right slider 202 is to facilitate the use of this application. Medical staff can lift the instep support member 20 by holding the upper part of the left slider 201 and the upper part of the right slider 202, so that the patient's lower limbs and feet can be correspondingly moved out of the lower limb fixing groove 1021 and the foot fixing groove 1011 of the lower limb lifting positioning member 10, making the application convenient to use.

[0089] Preferably, in the technical solution, according to an embodiment of the present invention, the present invention further comprises a left connecting block 30 and a right connecting block 40 arranged along the front-back direction and a gripping rod 50 arranged along the left-right direction;

[0090] The upper end surface of the foot support block 101 is provided with a left slide groove B1014 adapted to fit and fix the left connecting block 30 along the vertical direction at the rear side of the left slide groove A1012, and a right slide groove B1015 adapted to fit and fix the right connecting block 40 along the vertical direction at the rear side of the right slide groove A1013;

[0091] In addition, a left avoidance groove 1016 connected to the foot fixing groove 1011 is vertically formed at the rear end of the left slide groove B1014; a right avoidance groove 1017 connected to the foot fixing groove 1011 is vertically formed at the rear end of the right slide groove B1015;

[0092] Based on this, in the present application, the left end of the grip rod 50 extends into the left avoidance groove 1016 and is connected to the rear of the left connecting block 30; the right end of the grip rod 50 extends into the right avoidance groove 1017 and is connected to the rear of the right connecting block 40, so that its height is higher than the height of the elastic band 203.

[0093] Therefore, it can be clearly seen that, on the one hand, through the optimized design of the above-mentioned structure, the height of the grip rod 50 will be higher than the height of the elastic band 203. When the elastic band 203 is against the patient's instep, the grip rod 50 will not press on the patient's ankle and other parts of the lower limbs due to its higher height position, so that the present application is reliable to use. On the other hand, when the medical staff lifts the grip rod 50 upwards, they can simultaneously extract the left connecting block 30, the right connecting block 40, the left slider 201, the right slider 202 and the elastic band 203 upwards, so that the instep supporting piece 20 can be quickly detached, and the patient's lower limbs and feet can be quickly removed from the lower limb fixing groove 1021 and the foot fixing groove 1011 of the lower limb lifting positioning piece 10, making the present application more convenient to use.

[0094] In addition, in a specific implementation, according to an embodiment of the present invention, a plurality of anti-slip convex strips 501 are evenly arranged on the outer wall of the handle 50 along the left-right direction.

[0095] In this way, the medical staff can have good anti-slip property when holding the handle 50.

[0096] Furthermore, in the technical solution, according to one embodiment of the present invention, the present invention further comprises a support pad 60 for supporting the patient's lower limbs and feet;

[0097] The support pad 60 is removably stacked on the bottom of the lower limb fastening groove 1021 , and its front end extends into the foot fastening groove 1011 .

[0098] In this way, by providing the support pad 60, the patient's lower limbs and feet can be better supported during use. It can be used by one person and only needs to be replaced during use. As for the lower limb supporting positioning piece 10 and the instep supporting piece 20, they can be reused and can be cleaned and disinfected after each use.

[0099] Again, in a specific implementation, according to an embodiment of the present invention, the support pad 60 is made of soft rubber material, and a plurality of massage protrusions 601 are evenly protruded upward on the upper end surface of the support pad 60 .

[0100] In this way, the multiple massage convex points 601 can perform massage therapy on the patient's lower limbs and feet to dredge the meridians and promote blood circulation, thereby helping the patient's health.

[0101] It should be added that, in a specific implementation, according to one embodiment of the present invention, the front middle portion of the support pad 60 protrudes upward in the left-right direction to form an ankle supporting portion 602 for supporting the ankle.

[0102] Thus, by providing the ankle support portion 602, it is convenient to support the patient's ankle, making it more difficult for the patient's lower limbs to shift forward and backward, so that when performing a CT scan on the patient's lower limbs and feet, the stability of the patient's lower limbs and feet being fixed during the examination can be greatly improved.

[0103] It is further necessary to add that, according to one embodiment of the present invention, the left end surface of the lower limb lifting and positioning member 10 is provided with a male Velcro 103, and the right end surface is provided with a female Velcro 104;

[0104] Comparison Figure 6 As shown, when the two lower limb image scanning foot positioning devices 1000 are arranged closely together so that the female Velcro 104 and the male Velcro 103 are adhered to each other in relative position, the two lower limb image scanning foot positioning devices 1000 are fixed together as a whole.

[0105] In this way, when a CT scan is required on both lower limbs and feet of a patient, two of the present applications can be used, and the two applications can be connected together to fix the patient's lower limbs and feet in position, making the present application more flexible to use.

[0106] At the same time, according to an embodiment of the present invention, the bottom surface of the lower limb supporting positioning member 10 is formed into a serrated structure to form an anti-slip placement surface 105.

[0107] In this way, even when the present application is placed on a CT scanning bed, the stability of the present application itself can be improved.

[0108] It should be further added that, in specific implementation, according to the lower limb image scanning foot positioning device 1000 provided in the embodiment of the present invention, the present application can be designed in three sizes: large, medium and small, to adapt to the lower limbs of patients with different sizes of lower limbs, so that the present application can be used selectively.

[0109] Other embodiments and the like are not described here by way of example.

[0110] To summarize, the lower limb imaging scanning foot positioning device 1000 provided by the present application, during specific implementation, is placed on a CT scanning bed so that the patient lies flat on the CT scanning bed, and the lower limbs and feet that need to undergo CT scanning are placed in the lower limb clamping groove 1021 and the foot clamping groove 1011 accordingly, so that the soles of the patient's feet are as closely fitted as possible with the front inner end surfaces of the foot clamping grooves 1011. After the patient's lower limbs and feet are stably supported, the patient's instep is clamped by the instep support fixture 20, so that the toes of the patient's feet are kept as upward as possible. Then, the CT machine can be started and the patient's lower limbs and feet that need to be examined are sent into the CT machine for CT examination. In this way, the present application can be easily used.

[0111] By providing the lower limb lifting positioning member 10, the patient's lower limbs and feet that need to undergo CT scanning can be better placed in the lower limb fixing groove 1021 and the foot fixing groove 1011 to be limited and not easily shaken left and right. By providing the instep support member 20, the patient's instep is supported so that the toes of the patient's foot can be kept in an upward posture as much as possible. In this way, the patient's foot CT examination scanning posture and the patient's foot CT examination scanning length range can be effectively controlled, so as to greatly reduce the CT examination scanning cost and greatly reduce the workload of medical staff, so that the CT examination of the patient's lower limbs and feet can become easier and more time-saving, and the instep support member 20 can slide upward to facilitate the removal of the patient's foot.

[0112] Furthermore, before using the present application, the instep support piece 20 can be detached from the lower limb lifting and positioning piece 10, so that it is convenient for the patient's foot to be inserted into the foot fixing groove 1011, and then the left slider 201 can be inserted into the left slide groove A1012, and the right slider 202 can be inserted into the right slide groove A1013. When they fall naturally, the elastic band 203 can be fixed to the instep of the patient's foot, so that the toes of the patient's foot can be kept as upward as possible and fixed, so that the use of the present application can indeed facilitate CT examination of the patient's lower limbs and feet.

[0113] And through the optimized design of the structure, the height of the grip rod 50 is higher than the height of the elastic band 203. When the elastic band 203 is against the patient's instep, the grip rod 50 will not press on the patient's ankle and other parts of the lower limbs due to its higher height, so that the application is reliable to use. When the medical staff lifts the grip rod 50 upwards, they can simultaneously extract the left connecting block 30, the right connecting block 40, the left slider 201, the right slider 202 and the elastic band 203 upwards, so that the instep supporting piece 20 can be quickly disassembled, and the patient's lower limbs and feet can be quickly removed from the lower limb fixing groove 1021 and the foot fixing groove 1011 of the lower limb lifting positioning piece 10, making the application more convenient to use.
