Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic examination, and specifically relates to a fixing device for ultrasonic examination. Background Art

[0002] Musculoskeletal ultrasound elastography is a type of ultrasonic elastography detection. By evaluating the elastic and hardness characteristics of muscles through ultrasonic elastography detection, it is a supplementary means for conventional ultrasonic detection. Musculoskeletal ultrasound elastography is usually performed when the patient's muscles are relaxed. When performing ultrasound elastography examinations on different parts of the muscles, different body positions are required. However, patients usually cannot actively cooperate with doctors for examinations. Although some patients can assume the specified body positions, they still cannot relax their muscles for examinations, which will lead to poor examination results. Moreover, when existing patients undergo ultrasonic elastography detection, they generally lie flat on the bed. When the patient lies flat on the bed for detection, in order to achieve a better imaging effect, the doctor needs to go to the other side of the bed for detection. When performing the examination, the position needs to be changed to obtain a better imaging effect, which is inconvenient to use. At the same time, auxiliary fixing tools are also needed to assist the patient in assuming the correct body position and keeping the muscles in a relaxed state to improve the accuracy during the examination and facilitate better completion of the examination.

[0003] Therefore, we have proposed a fixing device for ultrasonic examination. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This fixing device for ultrasonic examination:

[0016] 1. When installing the device, only need to insert the fixed bottom plate into the outer surface of one side of the bed board, and then turn the threaded handle to drive the pulling block to move, so that the pulling block can move and push the jacking clamping block to rise, so that the jacking clamping block can drive the rubber pad to clamp the bed board. While facilitating the installation and fixation of the device, the lower body that needs ultrasonic examination of the patient can be located outside the bed when lying on the device, without having to move around the bed for better imaging effects, making it convenient for doctors to perform examination operations.

[0017] 2. After the fixed bottom plate is fixed on the outer surface of one side of the bed board, the fixed bottom plate can be separated from the support plate, and adjusted and tightened according to the leg length of the patient. After turning down the sleeve rod and pulling the elastic pin, the sliding support rod can be released, so that the sliding support rod can drive the floor mat to fall. The influence caused by the ground inclination can be eliminated through the floor mat, so that the device can be conveniently folded, telescoped and stored, and the support stability of the support plate can be improved through the sleeve rod and the sliding support rod, making the device convenient for installation, folding, storage and transportation.

[0018] 3. When it is necessary to examine the inner side of the patient's leg, only need to lift the positioning rod and move it to an appropriate distance and then release it, so that the tooth block concave chute can be engaged with the tooth block card slot. Through the weight of the patient's leg placed on the rotating support frame and the elastic sponge and the weight of the rotating support frame and the elastic sponge itself, the positioning rod can be automatically fixed and adjusted, and the comfort of the patient during use can be improved through the rotating support frame and the elastic sponge, facilitating the adjustment of the fork angle between the patient's legs for examination.

[0019] 4. By opening the crank and rotating it, the worm can be driven to rotate, so that the worm gear meshing with the worm can rotate accordingly. Through the rotation of the worm gear, the gear is driven to rotate, so that the gear can drive the rack to rise together. And due to the self-locking property of the worm gear and the worm, after the rotating support frame and the elastic sponge rise, they will not automatically fall, enabling the patient's leg to rise and lift, facilitating the doctor to perform ultrasonic examination under the patient's leg.

[0020] 5. After the patient places the leg on top of the rotating support frame and the elastic sponge, the sliding extension rod can be adjusted according to the length of the patient's leg, so that the patient's leg or foot can rest on the outer surface of the pedal rope. Then, the threaded handle can be turned to push the positioning plug rod to move, so that the positioning plug rod can be inserted into the limit slot to fix the position of the sliding extension rod, enabling the patient's leg and foot to rest on the outer surface of the pedal rope, relaxing the muscles of the patient's leg, and making it more accurate for the doctor during the examination.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 - 11 , the present invention provides a technical solution: a fixing device for ultrasonic examination, including a fixed bottom plate 1, the fixed bottom plate 1 is inserted on the outer surface of the bed board, and a support plate 7 is slidably installed on the outer surface of the fixed bottom plate 1 away from the bed board. A sleeve rod 8 is rotatably installed on the outer surface of the support plate 7. A threaded turning handle 3 is threadedly installed on the side surface of the fixed bottom plate 1, and the threaded turning handle 3 is located below the fixed bottom plate 1. A moving clamping mechanism is arranged between the fixed bottom plate 1 and the threaded turning handle 3. Through the moving clamping mechanism, it is convenient to install the device and can conveniently adjust the position for the doctor to perform the examination.

[0035] That is, the edge of the fixed bottom plate 1 is provided with corresponding notches, and the notches can be inserted and matched with the edge of the bed board. By inserting the fixed bottom plate 1 on the outer surface of the bed board, the device can extend out of the bed surface, so that the patient's leg at the examination part can extend out of the bed when in use, and the doctor does not need to go to the other side of the bed during the examination, which can save the time consumed during movement and improve the accuracy during the examination.

[0036] The moving clamping mechanism includes: a pulling block 2, the pulling block 2 is slidably arranged inside the fixed bottom plate 1, and a lifting and clamping block 4 is placed inside the fixed bottom plate 1, and the outer surface of the lifting and clamping block 4 is attached to the outer surface of the pulling block 2. A threaded turning handle 3 is rotatably installed on the side surface of the pulling block 2. Rubber pads 5 are respectively fixedly pasted on the outer surfaces of the lifting and clamping block 4 and the fixed bottom plate 1, and the outer surface of the rubber pad 5 is attached to the outer surface of the bed board.

[0037] After inserting the fixed bottom plate 1 into one side of the bed board, the threaded turning handle 3 can be tightened. By turning the threaded turning handle 3, the pulling block 2 can be driven to move, so that the pulling block 2 can squeeze the jacking clamping block 4, enabling the jacking clamping block 4 to slide inside the fixed bottom plate 1 and rise together with the rubber pad 5, so that the fixed bottom plate 1 and the jacking clamping block 4 can move and clamp the bed board. And through the friction force of the rubber pad 5, the fixed bottom plate 1 can be more firmly fixed after being fixed, making the device easy to install and convenient to adjust the position of the fixed bottom plate 1 beside the bed, so that the doctor can adjust the position of the device according to the patient's condition.

[0038] Adopting the above technical solution, by turning the threaded turning handle 3, the pulling block 2 can be pulled to move. Through the movement of the pulling block 2, the jacking clamping block 4 is pushed to move and rise, so that the jacking clamping block 4 drives the rubber pad 5 to move upward and abut against the bottom of the bed board, cooperating with the fixed bottom plate 1 to clamp the bed board, and increasing the friction force during clamping through the rubber pad 5, making the device not easy to fall off the bed board. The whole device is convenient to install, enabling the device to be installed on the outside of the bed, so that when the doctor examines the patient's leg, the patient's leg can extend out of the bed for the doctor to examine, without the doctor having to move around the bed for monitoring, reducing the cumbersome nature caused by movement during the examination, and improving the convenience and accuracy during the examination.

[0039] An elastic cushion 6 is fixedly installed on the outer surface of the fixed bottom plate 1, and one side of the elastic cushion 6 covers the outer surface of one side of the fixed bottom plate 1. Grooves are provided on the outer surface of the elastic cushion 6.

[0040] Through the grooves of the elastic cushion 6, after the patient sits into the elastic cushion 6, the elastic cushion 6 can limit the position of the patient's buttocks, so that the patient will not move randomly during the examination, and at the same time, the comfort of the patient during use can be improved.

[0041] Adopting the above technical solution, the grooves on the outer surface of the elastic cushion 6 can limit the patient's buttocks. At the same time, by wrapping the side surface of the fixed bottom plate 1 with the elastic cushion 6, the probability of the fixed bottom plate 1 bruising the patient can be reduced, making the patient more comfortable during use.

[0042] The outer surface of the fixed bottom plate 1 is fitted with the outer surface of the support plate 7, and one end of the support plate 7 is located inside the fixed bottom plate 1. A positioning tightening bolt 12 is threadedly installed on the outer surface of the fixed bottom plate 1, and the outer surface of one end of the positioning tightening bolt 12 is fitted with the outer surface of the support plate 7.

[0043] That is, the support plate 7 is provided with a protruding support rod, and one end of the fixed base plate 1 is provided with a cavity that matches the sliding sleeve of the support rod, and the positioning and tightening bolt 12 threadedly penetrates the surface of the fixed base plate 1 and abuts against the support rod. After the fixed base plate 1 is fixedly installed on the bed board, the support plate 7 can be pulled and the position of the support plate 7 can be adjusted according to the patient's leg length. Then the positioning and tightening bolt 12 can be tightened so that the position of the fixed base plate 1 and the support plate 7 can be fixed, so that patients with different leg lengths can use it.

[0044] By adopting the above technical solution, the distance between the fixed base plate 1 and the support plate 7 can be adjusted by sliding the fixed base plate 1 and the support plate 7 and tightening the positioning tightening bolts 12 to meet the comfortable use needs of patients with different leg lengths.

[0045] A sleeve rod 8 is rotatably mounted on one end of the support plate 7 away from the elastic cushion 6, and a block-shaped protrusion is provided at one end of the sleeve rod 8. A sliding clamping mechanism is provided between the sleeve rod 8 and the support plate 7. The support plate 7 can be supported by the sliding clamping mechanism, so that the device can be suitable for beds of different heights.

[0046] Through the rotation of the sleeve rod 8 and the block-shaped protrusion, the sleeve rod 8 can support the support plate 7 after opening. The block-shaped protrusion prevents the support plate 7 from rotating and deviating when subjected to force. At the same time, the sleeve rod 8 can be rotated and stored. At the same time, by fixing the bottom plate 1 and the sliding of the support plate 7, the device can be conveniently stored and moved.

[0047] The sliding locking mechanism includes: a sliding support rod 9, which is slidably inserted into the interior of a sleeve rod 8, and an elastic pin 11 is slidably installed on the side surface of the sleeve rod 8, a circular hole is provided on the side surface of the sliding support rod 9, and the circular hole on the outer surface of the sliding support rod 9 is engaged with the elastic pin 11, and a ground pad 10 is rotatably installed on the outer surface of one end of the sliding support rod 9.

[0048] When in use, the sleeve rod 8 needs to be lowered, and then the elastic pin 11 can be pulled to separate the elastic pin 11 from the sliding support rod 9, so that the sliding support rod 9 can descend and drive the foot pad 10 to descend together, so that the foot pad 10 can contact the ground, and the foot pad 10 can stably support the support plate 7 when the ground is tilted, so that beds of different heights can be used and can be conveniently stored and folded.

[0049] By adopting the above technical solution, during installation, it is only necessary to rotate the sleeve rod 8 to a vertical state, and then adjust the sliding support rod 9 by pulling the elastic pin 11. After ensuring that the ground pad 10 is in contact with the ground, the elastic pin 11 is engaged with the circular hole of the sliding support rod 9 to determine the length of the sleeve rod 8 and the sliding support rod 9. At the same time, the provided ground pad 10 can meet the installation requirements when the ground is slightly inclined, so that the extended support plate 7 can also be subjected to force.

[0050] Tooth block concave sliding grooves 14 are provided on the outer surfaces at both ends of the pallet 7, and positioning rods 15 are slidably installed inside the tooth block concave sliding grooves 14. Limiting screw rods 13 are threadedly installed on the outer surfaces at both ends of the pallet 7, and the limiting screw rods 13 are located inside the tooth block concave sliding grooves 14. Tooth block clamping grooves 16 are fixedly installed on the outer surfaces at both ends of the positioning rod 15, and the tooth block clamping grooves 16 are engaged with the tooth block concave sliding grooves 14. The limiting screw rod 13 can block one end of the tooth block concave sliding groove 14.

[0051] Through the limiting screw rod 13, the positioning rod 15 placed inside the tooth block concave sliding groove 14 can be limited, so that the positioning rod 15 can be conveniently installed and cannot be removed from the tooth block concave sliding groove 14. When the position of the positioning rod 15 needs to be adjusted, only the positioning rod 15 needs to be lifted to move it. After the positioning rod 15 moves to the limited position, the positioning rod 15 can be released. Through the engagement of the tooth block clamping groove 16 on the outer surface of the positioning rod 15 with the tooth block concave sliding groove 14, that is, the tooth block concave sliding groove 14 is provided with a gap that allows the tooth block clamping groove 16 part to move up and down, and the weight of itself and the weight of the patient's leg enable the set rotating support frame 18 and elastic sponge 19 to be fixed, and the distance between the patient's legs can be adjusted, which is convenient for doctors to perform examinations and adjustments.

[0052] Adopting the above technical solution, the positioning rod 15 slidably arranged inside the tooth block concave sliding groove 14 can be limited by the limiting screw rod 13. At the same time, the positioning rod 15 can be moved by lifting it. After the positioning rod 15 is put down, the tooth block concave sliding groove 14 will be engaged with the tooth block clamping groove 16, and the positioning rod 15 will be fixed by its own weight and the weight of the leg, and the position of the positioning rod 15 can be restricted, so that the patient's legs can be opened, adjusted and supported, which is convenient for examinations.

[0053] A rack 17 is slidably installed inside the positioning rod 15, and one end of the rack 17 located outside the positioning rod 15 is rotatably installed with the rotating support frame 18. One end of the rotating support frame 18 close to the elastic cushion 6 is inclined. An elastic sponge 19 is fixedly installed on the outer surface of the rotating support frame 18, and the elastic sponge 19 and the rotating support frame 18 are designed in a C shape. A rotating lifting mechanism is arranged between the positioning rod 15 and the rack 17. Through the rotating lifting mechanism, it is convenient to lift the positions of the rotating support frame 18 and the elastic sponge 19. The rotating support frame 18 and the elastic sponge 19 are used to support and place the patient's legs, so that the patient's thighs and calves can be lifted, which is convenient for examining the lower part of the patient's legs.

[0054] Through the C-shaped design of the rotating support frame 18 and the elastic sponge 19, when the patient's leg is placed on the rotating support frame 18 and its position is changed, it will not easily fall. Moreover, due to the inclined design on one side of the rotating support frame 18, the rotating support frame 18 can be limited during movement, enabling the rotating support frame 18 to lean against the patient's leg obliquely. Additionally, the elastic sponge 19 can improve the comfort of the patient when the device is in use.

[0055] With the above technical solution, through the inclined design at one end of the rotating support frame 18, the rotating support frame 18 can be inclined. At the same time, the C-shaped design of the rotating support frame 18 and the elastic sponge 19 can limit the patient's leg, and together with the elastic sponge 19, the patient's leg can fit more comfortably with the rotating support frame 18 and the elastic sponge 19.

[0056] The rotation and lifting mechanism includes: a gear 20, the gear 20 is rotatably installed inside the positioning rod 15, and a worm gear 21 is rotatably installed inside the positioning rod 15. The worm gear 21 and the gear 20 are concentrically designed, and the gear 20 meshes with the rack 17. That is, the worm gear 21 and the gear 20 are coaxially and fixedly connected by a shaft rod, and the shaft rod is rotatably connected to the inside of the positioning rod 15. A worm 22 is rotatably installed inside the positioning rod 15, and the worm 22 meshes with the worm gear 21. One end of the worm 22 located outside the positioning rod 15 is rotatably installed with a crank 23.

[0057] When it is necessary to detect the area below the patient's leg, only need to pull down and rotate the crank 23, which can drive the worm 22 to rotate together. Through the rotation of the worm 22, the worm gear 21 is driven to rotate together, enabling the gear 20 to drive the rack 17 engaged with it to rise together. At the same time, due to the self-locking property of the worm gear 21 and the worm 22, the rotating support frame 18 and the elastic sponge 19 will not automatically fall, allowing the patient's leg to maintain its position after the position adjustment is completed, facilitating the doctor to examine the area below the patient's leg.

[0058] With the above technical solution, the crank 23 can be folded and stored. The crank 23 can rotate the worm 22, and through the rotation of the worm 22, the worm gear 21 is driven to rotate together. As the worm gear 21 rotates, the gear 20 is driven to rotate, enabling the gear 20 to rotate and drive the rack 17 to perform a lifting and lowering movement operation, that is, it can control the rack 17 to move upward, ultimately enabling the rotating support frame 18 and the elastic sponge 19 to be lifted upward, allowing the patient's thigh and calf to be lifted up for the doctor to conduct an examination. And due to the self-locking property of the worm gear 21 and the worm 22, the rotating support frame 18 and the elastic sponge 19 will not automatically fall and cause accidental injury to the patient.

[0059] One end of the outer surface of the support plate 7 is slidably installed with a sliding extension rod 24, and a pedal rope 25 is rotatably installed between the sliding extension rods 24. The outer surface of the sliding extension rod 24 is evenly provided with limit slots 26. A positioning plug rod 27 is slidably installed inside the support plate 7, and a threaded handle 28 is rotatably installed on the outer surface of the positioning plug rod 27, and the threaded handle 28 is threadedly connected to the support plate 7.

[0060] After the patient's leg is placed on the device, only need to pull out the sliding extension rod 24 according to the patient's leg length, and then rotate the threaded handle 28 to push the positioning plug rod 27 to rise, so that the positioning plug rod 27 can be inserted into the inside of the limit slot 26 to fix the length of the sliding extension rod 24, so that the patient's leg or foot can be placed above the pedal rope 25, enabling the patient's leg to exert force, allowing the patient's leg to be comfortably placed on the device, and can be adjusted according to the patient's leg length, and the patient's leg muscles can be relaxed by exerting force.

[0061] With the above technical solution, through the sliding of the sliding extension rod 24, the patient's foot can be placed on the outer surface of the pedal rope 25, and by tightening and fixing the threaded handle 28, the positioning plug rod 27 can be pushed to move and rise, so that the positioning plug rod 27 can be embedded into the inside of the limit slot 26 to limit and fix the length of the sliding extension rod 24, meeting the use of patients with different calf lengths, enabling the patient's leg to exert force and be placed after being lifted, and relaxing the calf muscles for convenient examination by the doctor.
