Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular is an MRI imaging diagnostic device. Background Art

[0002] MRI is magnetic resonance imaging, which is a type of tomographic imaging. It uses an external strong magnetic field and radio frequency pulses to excite hydrogen atoms in the human body to produce nuclear magnetic resonance signals, and then converts the signals into images through spatial encoding technology. Nuclear magnetic resonance (MRI) has been applied to imaging diagnosis of various systems in the body, with the best results in the brain, nerves, heart and large blood vessels, joints and bones, soft tissues, etc. For cardiovascular diseases, it can not only observe the anatomical changes of various chambers, large blood vessels and valves, but also perform ventricular analysis, conduct qualitative and semi-quantitative diagnosis, and can make multiple cross-sectional images with high spatial resolution, which is conducive to showing the overall picture of the heart and lesions, and is superior to other X-ray imaging, two-dimensional ultrasound, radionuclide and CT examinations.

[0003] After searching, a Chinese patent discloses an MRI imaging diagnostic device (Announcement No.: CN218738933U), whose main structure includes a base, on which is provided: a detector body, on which is provided a detection channel; an examination bed, which is arranged at one end of the detection channel and can slide back and forth along the detection channel under the drive of a first horizontal driving member; an auxiliary bed, which is arranged at one side of the examination bed and can be raised and lowered; a protective baffle, which is arranged between the auxiliary bed and the examination bed, and the base is provided with a first lifting driving member for driving the protective baffle to rise and fall; a metal detection assembly, which is rotatably mounted on the protective baffle, and the protective baffle is also provided with a second horizontal driving member for driving the metal detection assembly to move horizontally along the protective baffle.

[0004] In actual use, the above patent sets a liftable auxiliary bed in parallel on one side of the examination bed, making it convenient for patients to get on the examination bed for examination.

When the patients lie on the auxiliary bed, they need to be supported by their family members to help them lie down or stand up, which is time-consuming and laborious, reducing the diagnosis efficiency. In addition, the space in the diagnosis department is limited, and the accompanying family members are crowded in the diagnosis department, which is easy to affect the diagnosis and treatment environment. Therefore, it needs to be improved. Summary of the invention

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention adopts the coordinated design of structures such as the bottom shell and the lying-flat restraint mechanism, and drives the base to move by the driving mechanism. The driving mechanism can synchronously drive the back plate to realize up and down flipping, and at the same time, the leg rest can be synchronously driven to gradually flip when the bottom moves, and the two restraint blocks can be synchronously driven to approach or move away from each other through the linkage mechanism, so that the patient can lie flat and limit the patient's head and arms by approaching each other while the two restraint blocks are convenient for the patient to lie flat. When the patient stands up, the two restraint blocks can move away from each other and separate from the patient's head and arms, which helps to improve the accuracy of the patient's diagnosis and avoid misdiagnosis caused by the patient's body movement during diagnosis. It can assist the patient to automatically lie flat and stand up, which improves the diagnosis efficiency. No need for the support of accompanying family members, reduces the number of family members waiting in the diagnosis department, helps to improve the diagnosis environment, and solves the problem that some patients in the prior art suffer pain in the waist when lying flat or bending due to their old age or illness. When the patient lies on the auxiliary bed, the accompanying family members need to support and help the patient lie flat or stand up, which is troublesome and laborious, reduces the diagnosis efficiency, and the space of the diagnosis department is limited, and the accompanying family members are crowded in the diagnosis department, which is easy to affect the diagnosis and treatment environment.

[0020] 2. The present invention adopts the coordinated design of structures such as a restraining block and a decompression mechanism. When the patient lies flat and the earmuffs cover the patient's ears, the soundproof chamber is filled with water through an electric circulating water tank, which can further enhance the noise isolation. The water in the soundproof chamber flows into the water flow chamber through a connecting pipe, and then the sound of the falling water is transmitted to the patient's ears through the earmuffs through the sound-transmitting copper tube. The sealing plate can be driven up and down by rotating the adjusting screw. The position height of the sealing plate can be adjusted to adjust the distance of the falling water flow, thereby changing the size of the water flow sound. The water flow sound is easily transmitted to the sound-transmitting copper tube through the docking copper tube. The continuous and stable sound of the water flow can soothe the patient's irritability and tension, effectively reduce the patient's psychological pressure, and is beneficial to the patient's physical and mental health.

DETAILED DESCRIPTION

[0030] 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.

[0031] like Figures 1 to 8 As shown, the present invention provides an MRI imaging diagnostic device, comprising a detector body 1 for diagnosing a patient's brain, a bottom shell 2 fixedly mounted on the right side of the detector body 1, and a lying-flat restraint mechanism 3 arranged above the bottom shell 2 for fixing the patient's limbs to assist the patient in lying flat and standing up; wherein the detector body 1 is a prior art, and its structure and principle are not described in detail here;

[0032] The lying-flat restraint mechanism 3 includes a bottom plate 31 arranged above the bottom shell 2 for supporting the patient's buttocks, a back plate 32 hinged on the left side wall of the bottom plate 31 for supporting the patient's back, a leg support 33 hinged on the right side wall of the bottom plate 31 for supporting the patient's legs, two restraint blocks 34 symmetrically moving forward and backward on the left side of the upper surface of the back plate 32 for limiting the patient's head and shoulders, two earmuffs 35 symmetrically fixed on the inner side walls of the two restraint blocks 34 for soundproofing the patient's ears, and a soundproofing device 34 arranged at the lower part of the two restraint blocks 34 and inside the earmuffs 35 for soundproofing the patient's ears. A decompression mechanism 36 for relieving the patient's tension, a base 39 that moves left and right in the bottom shell 2 to drive the bottom plate 31 to move, a driving mechanism 37 arranged in the bottom shell 2 and on the base 39 to drive the bottom plate 31 and the back plate 32 to move, and a linkage mechanism 38 arranged at the bottom of the back plate 32 to drive the two restraint blocks 34 to move; wherein, when the driving mechanism 37 is operated, the driving linkage mechanism 38 is operated, the bottom surface of the leg rest 33 abuts against the upper surface of the bottom shell 2, and the lower part of the restraint block 34 penetrates to the bottom surface of the back plate 32.

[0033] During use, when the patient needs to stand up after the diagnosis is completed, the driving mechanism 37 drives the base 39 to drive the bottom plate 31 to move away from the detector body 1. During the movement, the driving mechanism 37 synchronously drives the back plate 32 to flip and stand upright, so that when the back plate 32 is flipped and stood upright, it can drive the patient to sit up. At the same time, when the bottom plate 31 moves, it drives the leg rest 33 to move. The leg rest 33 gradually flips downward during the movement, driving the patient's legs to hang down, so that the patient can automatically sit up after the diagnosis is completed, which is convenient for the patient to stand up, thereby improving the diagnostic efficiency. There is no need for accompanying family members to support, which reduces the number of family members waiting in the diagnosis department and helps to improve the diagnostic environment.

[0034] It should be noted that when the patient needs to lie flat for diagnosis, the driving mechanism 37 drives the bottom plate 31 toward the detector body 1. During the movement, the driving mechanism 37 synchronously drives the back plate 32 to flip down, and the bottom plate 31 drives the leg rest 33 to move. During the movement, the leg rest 33 gradually flips upward, so that the patient can lie flat slowly. At the same time, the two restraint blocks 34 are driven close to each other through the linkage mechanism 38. The restraint blocks 34 are close to each other and fit the patient's arms, which can limit the patient's arms and avoid misdiagnosis caused by movement of the patient's limbs during diagnosis, thereby improving the accuracy of the diagnosis.

[0035] It is worth mentioning that when the two restraining blocks 34 limit the position of the patient, the earmuffs 35 can cover the patient's ears to reduce the impact of the noise generated during the operation of the equipment on the patient. At the same time, the earmuffs 35 can be filled with water through the decompression mechanism 36, and the water can further isolate the noise, thereby improving the sound insulation effect. At the same time, the decompression mechanism 36 can drive the water to circulate, thereby generating a gurgling sound of flowing water, and transmit the sound of flowing water to the patient's ears through the earmuffs 35. The gurgling sound of flowing water has the effect of calming the mind, which can reduce the patient's irritability, tension and fear, reduce the patient's psychological pressure, and is beneficial to the patient's physical and mental health.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, the driving mechanism 37 includes a servo motor 371 fixedly mounted on the left side of the bottom surface of the inner cavity of the bottom shell 2, a driving screw 372 fixed on the output shaft end of the servo motor 371 for driving the base 39 to move, a driving rod 373 slidingly mounted on the upper part of the left side wall of the base 39, a push block 374 sliding horizontally on the bottom surface of the back plate 32, a connecting shell 375 vertically fixed on the left end of the driving rod 373, and a connecting rod 376 for connecting the push block 374 with the connecting shell 375; wherein, the left end of the connecting rod 376 is fixedly connected to the right side wall of the push block 374, and the right end of the connecting rod 376 is movably connected to the inner cavity of the connecting shell 375, and when the driving screw 372 rotates, the driving rod 373 moves in conjunction.

[0037] When in use, the servo motor 371 drives the driving screw 372 to rotate, thereby driving the base 39 to move. When the base 39 moves, it drives the screw 372 to synchronously drive the driving rod 373 to move. When the driving rod 373 moves, it can drive the push block 374 to move through the connecting rod 376 and the connecting shell 375. When the push block 374 moves, it interacts with the bottom surface of the back plate 32, so that the back plate 32 can be flipped up and down, thereby assisting the patient to lie down and stand up.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, a guide groove is circumferentially provided on the outer surface of the driving rod 373, and a sleeve 4 is sleeved on the driving rod 373. The outer surface of the sleeve 4 is movably connected to the left side wall of the base 39 through a bearing, and a guide block adapted to the guide groove is fixedly installed in the inner cavity of the sleeve 4. The outer surface of the sleeve 4 is fixedly sleeved with a first pulley 5, and the outer surface of the driving screw 372 is sleeved with a second pulley 6. The first pulley 5 and the second pulley 6 are connected by a transmission belt 7. The inner cavity of the second pulley 6 is slidably connected to the surface of the driving screw 372, and the outer surface of the second pulley 6 is movably connected to the lower part of the left side wall of the base 39 through a bearing.

[0039] When in use, the driving screw 372 rotates through the second pulley 6, the first pulley 5 and the transmission belt 7 to drive the sleeve 4 to rotate. When the sleeve 4 rotates, it can drive the driving rod 373 to move through the action of the guide block and the guide groove.

[0040] like Figure 2 and Figure 3 As shown, the linkage mechanism 38 includes a bidirectional screw rod 381 movably mounted on the bottom surface of the back plate 32 through a bearing for driving the two restraining blocks 34 to move, a docking gear 382 fixedly sleeved in the middle of the bidirectional screw rod 381, and a docking rack 383 fixed on the bottom surface of the push block 374 for driving the docking gear 382 to rotate.

[0041] When in use, the push block 374 moves left and right, driving the docking rack 383 to move. The docking rack 383 interacts with the docking gear 382 to drive the two-way screw 381 to rotate, so that the two-way screw 381 can drive the two restraining blocks 34 to move closer to or away from each other, so that the patient can lie flat while the two restraining blocks 34 move closer to each other to limit the patient's head and arms. At the same time, when the patient stands up, the two restraining blocks 34 can move away from each other and separate from the patient's head and arms, which helps to improve the accuracy of the patient's diagnosis and avoid misdiagnosis due to body movement during diagnosis.

[0042] like Figure 2 , Figure 6 and Figure 7 As shown, the pressure reducing mechanism 36 includes an electric circulating water tank 361 slidably mounted on the lower part of the two restraining blocks 34 through a bracket, a water flow chamber 362 opened on the upper part of the restraining block 34 and adapted to the position of the earmuff 35, a soundproof chamber 363 opened between the inner cavity and the outer wall of the earmuff 35, a sound transmission copper tube 364 running through the inner wall of the earmuff 35 and the inner cavity of the water flow chamber 362, and an adjusting mechanism 8 arranged in the inner cavity of the water flow chamber 362; wherein, the inner cavity top of the water flow chamber 362 is connected with the inner cavity top of the soundproof chamber 363 through a connecting pipe, the inner cavity lower part of the soundproof chamber 363 is connected with the water outlet port of the electric circulating water tank 361 through a soundproof hose, and the inner cavity of the water flow chamber 362 is connected with the water inlet port of the electric circulating water tank 361 through a rubber hose.

[0043] During use, when the patient lies down and the earmuffs 35 cover the patient's ears, the soundproof chamber 363 is filled with water through the electric circulating water tank 361, which can further enhance the noise isolation. The water in the soundproof chamber 363 flows into the water flow chamber 362 through the connecting pipe, and then the sound of the falling water is transmitted to the patient's ears through the earmuffs 35 through the sound-transmitting copper tube 364. The continuous and stable sound of the flowing water can soothe the patient's irritability and tension, effectively reduce the patient's psychological pressure, and is beneficial to the patient's physical and mental health.

[0044] like Figure 6 and Figure 7 As shown, the adjustment mechanism 8 includes a sealing plate 81 that moves up and down in the water flow chamber 362, an adjustment screw 82 that is vertically rotatably installed on the left side of the bottom surface of the inner cavity of the water flow chamber 362 for driving the sealing plate 81 to move, and a docking copper tube 83 fixed on the right side of the upper surface of the sealing plate 81; wherein, the top end of the adjustment screw 82 extends to the upper surface of the restraining block 34, the upper outer surface of the docking copper tube 83 is sealed and slidably connected with the lower inner cavity of the sound transmission copper tube 364, the top end of the rubber hose passes through the upper surface of the sealing plate 81, and the outer surface of the rubber hose is slidably connected with the bottom surface of the inner cavity of the water flow chamber 362.

[0045] When in use, the sealing plate 81 can be driven to move up and down by rotating the adjusting screw 82. By adjusting the position height of the sealing plate 81, the distance of the falling water flow can be adjusted, thereby changing the size of the water flow sound. The water flow sound can be transmitted to the sound transmission copper tube 364 through the docking copper tube 83.

[0046] like Figure 2 As shown, a rubber roller is rotatably mounted on the right side of the upper surface of the bottom shell 2, and the outer surface of the rubber roller is movably connected to the bottom surface of the leg support 33.

[0047] When in use, the rubber roller contacts the bottom surface of the leg rest 33 , so that the leg rest 33 can be easily turned over when moving, and the wear of the bottom surface of the leg rest 33 is reduced.

[0048] like Figure 5 As shown, a limiting groove for fitting the patient's arm is provided on the right portion of the inner wall of the restraining block 34, and a protective cotton pad is laid in the inner cavity of the limiting groove.

[0049] When in use, the inner cavity of the limiting groove fits against the patient's arm, so the patient's arm can be limited and fixed, and the protective cotton pad can protect the patient's arm skin to prevent the patient's arm skin from being squeezed and damaged.

[0050] The working principle and use process of the present invention:

[0051] When in use, the detector body 1 can be used to diagnose the patient's head condition. When the patient needs to lie flat for diagnosis, the servo motor 371 drives the driving screw 372 to rotate, thereby driving the base 39 to move. While the base 39 moves, it drives the screw 372 to drive the sleeve 4 to rotate through the second pulley 6, the first pulley 5 and the transmission belt 7. When the sleeve 4 rotates, it can drive the driving rod 373 to move through the action of the guide block and the guide groove. When the driving rod 373 moves, it can drive the push block 374 to move through the connecting rod 376 and the connecting shell 375. When the push block 374 moves, it interacts with the bottom surface of the back plate 32, so that the back plate 32 can be flipped down and lie flat, and the bottom plate 31 drives the leg rest 33 to move. During the movement, the leg rest 33 gradually flips upward, so that the patient can slowly lie flat; at the same time, when the push block 374 moves, it drives the docking rack 383 to move. Under the interaction of the docking rack 383 and the docking gear 382, ​​it can drive The two-way screw rod 381 rotates, so that the two-way screw rod 381 can drive the two restraining blocks 34 to approach each other, so that the patient can lie flat and limit the patient's head and arms by approaching the two restraining blocks 34. When the patient lies flat and the earmuffs 35 cover the patient's ears, the electric circulating water tank 361 fills the soundproof chamber 363 with water, which can further improve the noise barrier. The water in the soundproof chamber 363 flows into the water flow chamber 362 through the connecting pipe, and then the water flow sound emitted by the falling water flow is transmitted to the patient's ears through the earmuffs 364 through the sound transmission copper tube 364. The sealing plate 81 can be driven to move up and down by rotating the adjusting screw rod 82. By adjusting the position height of the sealing plate 81, the distance of the water flow falling can be adjusted, thereby changing the size of the water flow sound. The water flow sound is conveniently transmitted to the sound transmission copper tube 364 through the docking copper tube 83. The continuous and stable water flow sound can soothe the patient's irritability and nervous emotions, effectively reduce the patient's psychological pressure, and is beneficial to the patient's physical and mental health.

[0052] When the patient needs to get up after the diagnosis is completed, the servo motor 371 drives the base 39 to drive the bottom plate 31 to move away from the detector body 1, and synchronously drives the back plate 32 to flip and stand up, so that when the back plate 32 is flipped and stood up, it can drive the patient to sit up, and can synchronously move the two restraint blocks 34 away from each other and separate the patient's head and arms. At the same time, when the bottom plate 31 moves, it drives the leg rest 33 to move. The leg rest 33 gradually flips downward during the movement, driving the patient's legs to hang down, so that the patient can automatically sit up after the diagnosis is completed, making it easier for the patient to get up.
