Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a body position auxiliary adjustment device for magnetic resonance examination. Background Art

[0002] Magnetic resonance imaging (MRI) is a medical examination technique that uses strong magnetic fields and radio waves to produce detailed images of the human body's interior. This technique is non-invasive, non-invasive and harmless, and is widely used in the diagnosis, evaluation and treatment monitoring of a variety of diseases.

[0003] During the examination, appropriate adjustment of body position can improve the patient's comfort, minimize patient movement, and improve imaging quality. Secondly, different body position adjustments can also display different levels and details of the scanned area, thereby improving the accuracy of the examination.

[0004] However, in actual use, when the patient's position is adjusted for examination, due to the large-angle radio frequency field emission used in the MRI focusing or measurement process, its electromagnetic energy is converted into heat energy in the patient's tissue, causing the tissue temperature to rise (the situation is more obvious in patients with large areas of tattoos on the body), resulting in an increase in the patient's body surface temperature and causing discomfort to the patient.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1

[0038] See also Figures 1 to 10 The present invention provides a technical solution: a body position auxiliary adjustment device for magnetic resonance examination, comprising: a sliding frame 1 and an angle-adjustable support member 2, the support member 2 is installed inside the sliding frame 1, the sliding frame 1 is used to slide into the interior of the nuclear magnetic resonance, and the support member 2 is composed of three plates that rotate with each other, the plates on both sides can be adjusted in angle, for example, the plate close to the head can adjust the height of the patient's head after the angle is adjusted, thereby adjusting the patient's body position.

[0039] A plurality of through holes 3 are provided on the support member 2, and a telescopic tube 4 is slidably installed inside each of the through holes 3. Specifically, the telescopic tube 4 includes a first connecting tube 8 that slides in the through hole 3, the trigger member 6 is installed on the top of the first connecting tube 8, a hose 9 is fixedly installed on the bottom of the first connecting tube 8, a second connecting tube 10 is fixedly installed on the bottom of the hose 9, the second connecting tube 10 is connected to the cold air supply member 7, a slider 11 is fixedly installed on the bottom of the first connecting tube 8, a limit frame 12 is slidably installed on the outer side of the slider 11, the bottom of the limit frame 12 is fixed to the top of the second connecting tube 10, a limit rod 13 is fixedly installed in the limit frame 12, and a first spring 14 is sleeved on the outer side of the limit rod 13.

[0040] Through the above technical solution, the first connecting tube 8 can slide in the perforation 3, and the first connecting tube 8 and the second connecting tube 10 can also slide, that is, when the top of the first connecting tube 8 is blocked, when the telescopic tube 4 continues to slide, the first connecting tube 8 will not continue to slide, and the slider 11 at the bottom of the first connecting tube 8 will slide on the limit rod 13 in the limit frame. When the first connecting tube 8 and the second connecting tube 10 slide relatively, the hose 9 between the first connecting tube 8 and the second connecting tube 10 is adaptively extended and retracted, and the first spring 14 is compressed during the sliding process, and the function of the limit rod 13 is also to limit the position of the first spring 14 to avoid it from detaching from the limit frame 12 during compression.

[0041] A trigger member 6 is installed on the top of the first connecting tube 8. When the trigger member 6 touches the patient, the telescopic tube 4 forms a passage. When the trigger member 6 does not touch the patient, the telescopic tube 4 forms a closed circuit. Specifically, the trigger member 6 includes an insertion rod 25 inserted into the top of the first connecting tube 8 and a first air hole 26 opened at the top of the first connecting tube 8. A fixing block 27 is evenly installed on the bottom of the insertion rod 25. The fixing block 27 is slidably installed on the inner side of the first connecting tube 8. A blocking rod 28 is fixedly installed on the top of the fixing block 27. The blocking rod 28 is located in the first air hole 26. A second spring 29 is fixedly installed on the bottom of the fixing block 27. A ring 30 is fixedly installed on the bottom of the second spring 29. The ring 30 is fixed on the inner side of the first connecting tube 8.

[0042] When the telescopic tube 4 is pushed upward, the insertion rod 25 at the top of the first connecting tube 8 will also move upward synchronously. When the insertion rod 25 touches the patient, the insertion rod 25 is subjected to resistance. When the telescopic tube 4 continues to slide, the insertion rod 25 moves downward relative to the first connecting tube 8 under the action of resistance. When the insertion rod 25 moves downward, it will drive the synchronous fixed block 27 to move. When the fixed block 27 moves downward, it will drive the blocking rod 28 connected thereto to separate from the first air hole 26. At this time, a passage is formed among the second connecting tube 10, the first connecting tube 8 and the first air hole 26. Since a large number of telescopic tubes 4 are provided, not all of the telescopic tubes 4 will touch the patient. Therefore, in the telescopic tube 4 that does not touch the patient, the insertion rod 25 at the top thereof will not be subjected to resistance, that is, the blocking rod 28 will not be separated from the first air hole 26, that is, a closed circuit is formed among the second connecting tube 10, the first connection and the first air hole 26.

[0043] A longitudinal tube 15 is fixedly installed at the bottom of the second connecting tube 10, and a transverse tube 16 is installed at the end of each longitudinal tube 15. A support plate 17 is fixedly installed at the bottom of the transverse tube 16 and the longitudinal tube 15. A telescopic member 5 is installed at the bottom of the support plate 17. The telescopic member 5 can adjust the height of the support plate 17, thereby realizing the overall telescopic tube 4.

[0044] Specifically, the telescopic member 5 includes two screws 18 rotating at the bottom of the support plate 17, and the bottom of each screw 18 is threadedly connected to a threaded sleeve 19, and the bottom of the threaded sleeve 19 is rotatably installed at the bottom of the sliding frame 1. A first bevel gear 20 is fixedly installed on the outer side of one side of the threaded sleeve 19, and a second bevel gear 21 is meshed on one side of the first bevel gear 20. A handle 22 is fixedly installed at the end of the second bevel gear 21, and the handle 22 is rotatably installed on the side of the sliding frame 1. A pulley 23 is fixedly installed at the bottom of the two threaded sleeves 19, and a transmission belt 24 is installed between the two pulleys 23.

[0045] Through the above technical solution, when adjusting the height of the support plate 17, it is only necessary to rotate the handle 22. When the handle 22 is rotated, the second bevel gear 21 is driven to rotate. When the second bevel gear 21 rotates, it meshes with the first bevel gear 20 to drive the first bevel gear 20 to rotate. When the first bevel gear 20 rotates, the threaded sleeve 19 on one side will rotate synchronously. When the threaded sleeve 19 on one side rotates, it will drive the pulley 23 at the bottom to rotate. The pulley 23 drives the threaded sleeve 19 on the other side to rotate through the transmission belt 24, thereby ensuring that the two threaded sleeves 19 can rotate synchronously. When the threaded sleeve 19 rotates, it cooperates with the internal screw 18 thread, so that the screw 18 is out of the threaded sleeve 19, thereby changing the overall length of the threaded sleeve 19 and the screw 18. When the screw 18 extends, it drives the top support plate 17 to move upward, thereby driving the overall extension and retraction of the telescopic tube 4.

[0046] A cold air supply component 7 is installed at the end of the cross tube 16, and the cold air supply component 7 can input cold air into the telescopic tube 4. Specifically, an air pump 32 is first fixedly installed at the bottom of the sliding frame 1, and the air outlet end of the air pump 32 is connected to the end of the cross tube 16. An air intake pipe 33 is fixedly installed at the air intake end of the air pump 32, and a fin 34 is fixedly installed on the outer wall of the air intake pipe 33. A cooling water tank 35 is provided on the outer side of the fin 34, and the cooling water tank 35 is fixed to the bottom of the sliding frame 1.

[0047] Through the above technical solution, cooling water can be pre-injected into the cooling water tank 35. The cooling water cools the fins 34 before use, and the fins 34 transfer the low temperature to the intake pipe 33, so that the temperature in the intake pipe 33 becomes lower. When the air pump 32 starts working, the gas drawn from the intake pipe 33 is cooled gas, and the air pump 32 passes the cooled gas through the cross pipe 16, the longitudinal pipe 15, the second connecting pipe 10 and the hose 9 into the first connecting pipe 8.

[0048] Therefore, in summary, when the patient is examined, the body position is first adjusted and a comfortable posture is maintained. After the posture is fixed, the medical staff can operate the telescopic member 5 to drive the telescopic tube 4 to extend from the perforation 3. When the telescopic tube 4 touches the patient, a passage is formed by the telescopic tube 4, and the telescopic tube 4 that does not touch the patient continues to extend upward. When the telescopic tube 4 that forms the passage is extended to a certain height, a human shape is formed. The outside of the human shape is the extended telescopic tube 4. The extended telescopic tube 4 can limit the patient's posture to avoid movement during detection, thereby further reducing the generation of artifacts. The telescopic tube 4 that forms the passage can deliver the cooling gas to the first air hole 26 when the air pump 32 is turned on, and spray it from the first air hole 26, thereby acting on the patient's body surface and reducing the patient's body surface temperature, thereby reducing the thermal effect during the patient's examination and improving the patient's comfort during the examination.

[0049] It should be further added that, since the first air hole 26 is in the most direct contact with the patient, the first air hole 26 may be blocked by the patient and the cooling air flow cannot flow out normally. Therefore, a second air hole 31 is opened on the side of the first connecting tube 8, and the fixing block 27 is located on the inner side of the second air hole 31. At this time, the fixing block 27 will block the second air hole 31 to prevent air leakage. When the insertion rod 25 encounters resistance, the insertion rod 25 will move downward. When the insertion rod 25 moves downward, it will simultaneously drive the fixing block 27 to move downward, so that the fixing block 27 is separated from the second air hole 31, and the cooling gas can be ejected from the second air hole 31 on the side of the first connecting tube 8 and act on the patient.

[0050] Embodiment 2

[0051] Since each patient has a different body shape, the number of telescopic tubes 4 forming the passage is different. When the number of telescopic tubes 4 in the passage is greater, the flow rate of the gas ejected from the first air hole 26 and the second air hole 31 will decrease when the pressure of the cold cutting airflow remains unchanged, thereby reducing the patient's comfort.

[0052] Therefore, a detection member 36 and an adjustment member 37 are installed on the side of the cross pipe 16 . The detection member 36 detects the air pressure in the cross pipe 16 , and the adjustment member 37 adjusts the pressure value of the air pump 32 according to the detection result of the detection member 36 .

[0053] In this embodiment, the detection member 36 is a pressure gauge, and the adjustment member 37 includes a transmission rod 38 fixed to the top of the pressure gauge knob, a coil spring 39 is fixedly installed on the outer side of the transmission rod 38, and a mounting box 40 is fixedly installed on the outer side of the coil spring 39, and the mounting box 40 is fixed to the top of the detection member 36. A ratchet 41 is fixedly installed on the outer wall of the transmission rod 38, and a pawl 42 is engaged with one side of the ratchet 41. The pawl 42 is rotatably installed on the top of the mounting box 40, and a third spring 43 is installed between the pawl 42 and the mounting box 40. An electromagnet 44 is provided on one side of the pawl 42, and the electromagnet 44 is fixed to the top of the mounting box 40.

[0054] Through the above technical solution, the detection member 36 is implemented to detect the pressure in the cross tube 16. When the number of telescopic tubes 4 forming the passage increases, the detection member 36 detects the pressure change in the cross tube 16. At this time, the medical staff can adjust the knob on the detection member 36 according to the value change of the detection member 36, that is, rotate the transmission rod 38. When the transmission rod 38 rotates, the pressure of the cross tube 16 will change. At the same time, the transmission rod 38 will drive the coil spring 39 and the ratchet 41 to rotate during the rotation process. When the coil spring 39 rotates, it will be charged. When the ratchet 41 rotates, the pawl 42 will not be restricted by the ratchet 41, and the ratchet 41 can rotate normally. When the adjustment is completed, the cross tube 16 will continue to work at the adjusted pressure, so that the pressure of the cooling airflow can be changed according to the changes in the patient's body shape, so that a stable airflow can be maintained on the patient. When the examination is completed, the air pump 32 and the electromagnet 44 will work at the same time, the air pump 32 will be turned off, and the electromagnet 44 will be energized. When the electromagnet 44 is energized, the pawl 42 will generate suction, so that the pawl 42 is separated from the ratchet 41. When the ratchet 41 is not restricted, the elastic force of the coil spring 39 will be released, thereby driving the transmission rod 38 to reverse. When the transmission rod 38 reverses, the pressure in the cross tube 16 is restored to the preset value.
