Description

Technical Field

[0001] The present invention relates to a brain diagnosis system, and in particular to an intelligent brain multimodal imaging diagnosis system. Background Art

[0002] The existing brain multimodal imaging diagnosis system is similar in appearance to a CT scanning device. After the patient lies flat on the machine bed, the position of the patient relative to the chassis is adjusted through a conveying device. The scanned image is displayed in real time on the screen in the form of a surface, and special diagnostic images are captured through manual control.

[0003] However, the existing equipment has some defects during use: ① Patients are prone to tension in a small testing environment, making it difficult for them to remain static for a long time; ② During the test, the patient's unconscious breathing, heartbeat, swallowing and other movements can easily cause motion artifacts in the image, affecting the image quality and the accuracy of the diagnosis; ③ The small space of the equipment leads to a narrow bed, and the bed adopts an integrated structure, which not only easily aggravates the patient's tension, but also makes it inconvenient for the patient to climb up and down and adjust during use.

[0004] To this end, technicians in this field have proposed an intelligent brain multimodal imaging diagnostic system. Through some minor improvements on existing equipment, it is convenient for patients to relieve tension during the test, maintain a steady breathing and heart rate, and make the equipment's test results more accurate and reliable. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an intelligent brain multimodal imaging diagnosis system, which arranges the prior art integrated examination bed into a folding structure that is easy to adjust. Not only can the extension length of each part of the folding bed be adjusted according to the height difference of the patients, but also the angles of different positions of the patient's body can be adjusted accordingly through the hinged adjustment plate to adapt to the human body, making the patient examination process more comfortable and relaxing. In addition, the airbags are arranged to support the patient's body and exert a certain squeezing force to increase the comfort. Combined with the arrangement of the decompression ball, it can not only be used to divert the patient's attention, but also can detect and record the changes in the strength of the patient's fingers as a reference for equipment detection, thereby eliminating detection errors caused by changes in the patient's emotions.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an intelligent brain multimodal imaging diagnosis system, including an equipment box, in which a device for detection is installed.

[0007] A folding bed is provided on one side of the equipment box to replace the integrated bed commonly seen in existing equipment. Although the integrated bed can avoid obstruction and interference to equipment inspection as much as possible during use, it is relatively narrow and has no boundary protection and other structures, which can easily increase the patient's tension. In order to prevent the patient's emotional changes from interfering with the inspection results, a more convenient and comfortable folding bed structure is specially provided.

[0008] The folding bed is provided with airbags, which can adjust the support angles of different parts of the patient's body to adapt to the patient's needs, and the airbags can provide cushioning and light pressure relief to the patient. After the airbags are inflated, the airbags form a soft support under the patient's body, and at the same time, the airbags can contact and push the patient's body, providing the patient with a certain sense of boundaries and security through touch.

[0009] A decompression ball is provided on the upper surface of the folding bed. The patient holds the decompression ball to divert attention and relieve psychological pressure. The narrow and silent environment can easily cause psychological pressure, and at this time, it is necessary to divert attention or relieve psychological pressure through some things. The decompression ball designed by technical personnel in this field based on this point provides a target of contact and venting for the patient under examination through skin contact.

[0010] During the examination, the patient holds the stress relief ball in his hand to transfer nervousness through the touch of the palm. In addition, when feeling nervous, the patient's fingers will tightly grip the stress relief ball. The stress relief ball monitors changes in the patient's finger grip strength, and the recorded grip strength data is used as a reference for diagnosis. When changes appear on the diagnostic screen, the monitoring data of the stress relief ball is referred to to determine whether the change is caused by nervousness.

[0011] Preferably, the folding bed comprises a fixed plate, which is directly driven and controlled by the device, and the lying patient can be translated to the examination position by adjusting the drive of the fixed plate.

[0012] The two ends of the fixed plate relative to the equipment box forward inspection direction are hingedly connected with adjustment plates. By adjusting the distance between the adjustment plate and the fixed plate, the folding bed can be adapted to patients of different heights, so that the folding bed can better fit the patient's body and meet the comfort needs.

[0013] The sides of the fixed plate are also symmetrically hinged with protective side plates. The protective side plates are hinged on both sides of the fixed plate to provide certain support for the patient, preventing the patient from rolling down due to excessive movements during the examination. At the same time, the support structure on the side can also provide psychological safety for the patient, and at the same time, the protruding structure will not hinder the inspection of the equipment.

[0014] Preferably, a fixing sleeve is fixedly connected to the lower surface of the fixing plate, and an extension rod is slidably engaged with the inner side of the fixing sleeve. The adjustment plate is installed through the extension rod and the installation distance between the adjustment plate and the fixing plate is adjusted. The adjustment plate installed through the fixing sleeve and the extension rod is convenient for adjusting the extension length of the folding bed and can adapt to the bodies of patients of different heights, forming a supporting structure at the patient's joints to avoid discomfort caused by squeezing the patient's joints, thereby increasing the patient's limb movements during the examination.

[0015] Preferably, a support plate is fixedly connected to the upper surface of the extension rod, the adjustment plate is hingedly arranged at one end of the support plate away from the fixed plate, and a positioning pin is inserted into the side surface of the end of the fixed sleeve.

[0016] During the adjustment process of the extension rod, the patient's body is supported by a support plate installed on the same horizontal plane as the fixing plate, and the angle is adjusted by the adjustment plate to form an angle at the patient's joints to improve comfort. Finally, the extension length of the extension rod is positioned by the positioning pin.

[0017] Preferably, the lower surface of the fixed plate is fixedly connected to a limiting support block corresponding to the protective side plate, and the deflection angle of the protective side plate is limited by the limiting support block, while the protective side plate is supported to prevent the hinge structure of the protective side plate from being damaged when the patient goes up and down.

[0018] A limiting rod is slidably connected between the fixed plate and the protective side plate, and the fixed plate and the protective side plate are limitedly connected by the limiting rod. After the patient lies flat on the folding bed, the hinged protective side plate is pushed upward, and the fixed plate and the protective side plate are positioned by the limiting rod to form support for the patient on the folding bed.

[0019] Preferably, the sides of the fixed plate and the protective side plate are provided with sliding grooves in parallel, and a slider is slidably engaged with the inner side of the sliding groove. The two ends of the limiting rod are respectively hingedly connected to the two sliders. After pushing the protective side plate close to the fixed plate, the slider at the end of the limiting rod is connected to the side of the fixed plate through the sliding groove, thereby completing the installation of the protective side plate on the side of the fixed plate.

[0020] A buffer spring is also provided on the inner side of the limit rod. The purpose of providing the buffer spring on the inner side of the limit rod is to buffer the patient's body movements. When the patient moves his body, the airbag squeezes the protective side plate, and there is a possibility that the airbag cannot discharge the gas in time and may be damaged. Therefore, the buffer spring is used to provide the protective side plate with mobility.

[0021] Preferably, a pressure valve is connected between adjacent airbags, and a plurality of the airbags are installed in strips from the middle of the folding bed to both sides. When inflated, the airbags are inflated from the middle of the folding bed to both sides simultaneously. When the air pressure in the middle airbag exceeds a certain limit, the adjacent airbags are inflated through the pressure valve to ensure the squeezing force of the airbags on the patient's body and to prevent the airbags from being damaged easily due to over-inflation.

[0022] A transparent column is fixedly connected to the side of the airbag, and two ends of the transparent column are respectively connected to the decompression ball and the airbag through the transparent column, so that the air pressure in the decompression ball connected by the transparent column and the air bag is balanced.

[0023] Preferably, a sealing ball is provided inside the transparent column. After the air pressure in the pressure relief ball and the air bag reaches equilibrium, the sealing ball is pushed by the air pressure to move inside the transparent column by changing the pressure applied to the pressure relief ball by changing fingers.

[0024] Airtight gaskets are arranged on the inner sides of the two ends of the transparent column corresponding to the sealing balls. When the airbag is not inflated, the gas pressure in the decompression ball pushes the sealing ball against the airtight gasket to ensure that the gas pressure in the decompression ball will not leak.

[0025] A decompression ring is also sleeved on the side of the decompression ball. When the patient holds the decompression ball, he or she can turn the decompression ring to divert attention and prevent tension.

[0026] The present invention discloses an intelligent brain multimodal imaging diagnosis system, which has the following beneficial effects:

[0027] 1. The intelligent brain multimodal imaging diagnosis system improves the beds used in conjunction with existing equipment and replaces them with folding beds. The folding beds provide patients with a more comfortable experience during the examination and avoid discomfort caused by the patient's joints squeezing the bed during long examinations. In addition, protective side panels and air bags provide boundary support for patients to avoid psychological pressure on patients caused by a small environment. A decompression ball is also provided, which the patient can hold to divert his attention. The decompression ball can also monitor and record changes in the strength of the patient's fingers during the examination, and compare the examination data to eliminate errors caused by the patient's emotional tension.

[0028] 2. The intelligent brain multimodal imaging diagnosis system uses a fixed plate as the fixed base of the folding bed. The two ends of the bed are extended by extension rods to set a support plate to support the human body. The adjustment plate hinged on the side of the support plate is used to adjust the deflection angle to adapt to the human joints, providing a more comfortable experience for those lying flat, avoiding the existing one-piece bed that does not conform to the human body structure, easily causes pressure on the joints, and increases the patient's limb movement problems.

[0029] 3. This intelligent brain multimodal imaging diagnostic system has multiple airbags arranged from the middle of the folding bed to both sides, and adjacent airbags are connected by pressure valves to ensure that the airbags are in close contact with the patient's body, and combined with the hinged protective side panels, they apply appropriate amounts of contact to the patient's body to soothe the patient's tension.

[0030] 4. This intelligent brain multimodal imaging diagnostic system connects a transparent column between the side of the airbag and the decompression ball. When the air pressure of the two is balanced, the movement of the sealed ball can be used to accurately identify the changes in the patient's force on the decompression ball, thereby effectively monitoring the patient's emotional fluctuations. By recording the movement of the sealed ball in the transparent column and combining it with the equipment's detection data, detection errors caused by changes in the patient's emotions can be eliminated, thereby increasing the accuracy of the equipment.

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are 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.

[0041] The embodiment of the present invention discloses an intelligent brain multimodal imaging diagnosis system;

[0042] According to the attached Figure 1 As shown, it includes an equipment box 1, in which equipment for detection is installed. However, the equipment in the prior art is provided with an integrated bed body on one side of the equipment box 1. When using it, the patient may easily feel physical discomfort when lying horizontally for a long time. In addition, due to the small space of the equipment, the patient may easily experience greater emotional fluctuations as the examination time continues during the examination. At the same time, it may cause the patient's limbs to move, affecting the examination result of the equipment. Therefore, the technicians in this field use a folding bed 2 to replace the integrated bed body in the existing equipment.

[0043] A folding bed 2 is arranged on one side of the equipment box 1, and an airbag 3 is arranged on the folding bed 2. The folding bed 2 can adjust the support angles of different parts of the patient, and the airbag 3 can provide cushioning and light pressure relief to the patient. Physical contact can provide the patient with a sense of boundaries, thereby making the patient feel more secure, making it less likely for emotional fluctuations to occur during the examination, and improving the accuracy of equipment inspection.

[0044] A stress relief ball 4 is provided on the upper surface of the folding bed 2. The patient holds the stress relief ball 4 to divert his attention and relieve psychological stress. The grip strength changes of the patient's fingers are monitored through the stress relief ball 4. The recorded grip strength data is used as a diagnostic reference to eliminate errors in the equipment's brain examination of the patient when the grip strength record fluctuates.

[0045] According to the attached Figure 2 As shown, the folding bed 2 includes a fixed plate 201, which is directly driven by the equipment to move closer to the equipment box 1. The two ends of the fixed plate 201 relative to the equipment box 1 in the direction of inspection are hingedly connected with adjustment plates 202. The deflection angle of the adjustment plate 202 is adjusted at the joints according to the patient's height, so as to better conform to the human body structure and avoid the hard folding bed 2 squeezing the patient's joints and causing discomfort. The sides of the fixed plate 201 are also symmetrically hinged with protective side plates 203. The protective side plates 203 form a protective structure on the periphery of the fixed plate 201 to enclose the patient's body, provide the patient with a sense of security, and alleviate the sense of oppression caused by the narrow folding bed 2 and the narrow equipment box 1.

[0046] According to the attached Figure 3 and attached Figure 4 As shown, a fixing sleeve 5 is fixedly connected to the lower surface of the fixing plate 201 , an extension rod 6 is slidably engaged on the inner side of the fixing sleeve 5 , and the adjustment plate 202 is installed through the extension rod 6 and the installation distance between the adjustment plate 202 and the fixing plate 201 is adjusted.

[0047] The adjustment plate 202 can adjust the installation distance with the fixed plate 201 through the extension rod 6, so as to adapt to the use of patients with different heights. The adjustment plate 202 is extended to the patient's joint position through the extension rod 6, and then the installation angle of the adjustment plate 202 relative to the fixed plate 201 is adjusted to adapt to the support of the human joints.

[0048] The upper surface of the extension rod 6 is fixedly connected to a support plate 7, and the adjustment plate 202 is hingedly arranged at one end of the support plate 7 away from the fixed plate 201. After adjusting the installation length of the extension rod 6, the support plate 7 can provide additional support for the patient's body, while also avoiding the problem that the directly hinged installation of the adjustment plate 202 is not suitable for supporting the joint position of the human body.

[0049] A positioning pin 8 is inserted into the side of the end of the fixing sleeve 5 , and the extending length of the extension rod 6 is positioned by the positioning pin 8 .

[0050] The lower surface of the fixed plate 201 is fixedly connected to the limiting support block 9 corresponding to the protective side panel 203, and the deflection angle of the protective side panel 203 is supported by the limiting support block 9. On the one hand, the opened protective side panel 203 forms an inclined structure to facilitate the patient to get on and off the folding bed 2, and on the other hand, the structural stability of the hinged protective side panel 203 is ensured.

[0051] A limiting rod 10 is slidably connected between the fixed plate 201 and the protective side plate 203, and the fixed plate 201 and the protective side plate 203 are limitedly connected by the limiting rod 10. After the patient lies flat on the folding bed 2, the protective side plate 203 is flipped over and the limiting rod 10 is used to install the protective side plate 203 on the edge of the fixed plate 201.

[0052] According to the attached Figure 4 and attached Figure 5 As shown, a slide groove 11 is provided in parallel on the sides of the fixed plate 201 and the protective side plate 203, and a slider 12 is slidably clamped on the inner side of the slide groove 11. The two ends of the limit rod 10 are respectively hingedly connected to the two sliders 12. After the slider 12 is taken out of the slide groove 11, the protective side plate 203 can be flipped. After the protective side plate 203 is installed through the limit rod 10, it generally will not slide and fall off under the squeezing of the patient's body.

[0053] A buffer spring 13 is also provided on the inner side of the limit rod 10. The limit rod 10 provided with the buffer spring 13 can provide a certain buffering effect. When the patient's body shakes, the airbag 3 is squeezed to a certain extent, and the squeezing can easily cause damage to the airbag 3. Therefore, a certain buffer space is provided for the equipment through the limit rod 10.

[0054] According to the attached Figure 6 As shown, a pressure valve 14 is connected between adjacent airbags 3, and multiple airbags 3 are installed in strips from the middle to both sides of the folding bed 2. When the airbags 3 are inflated, they are inflated from the middle to both sides. When the internal air pressure of the middle airbag 3 exceeds a certain limit under the squeeze of the patient's body, the adjacent airbags 3 will be inflated through the pressure valve 14, gradually forming a tight support for the patient's body.

[0055] A transparent column 15 is fixedly connected to the side of the airbag 3, and both ends of the transparent column 15 are respectively connected to the decompression ball 4 and the airbag 3. The air pressure in the decompression ball 4 and the airbag 3 is balanced in the transparent column 15, and the force on the decompression ball 4 can be monitored by observing the transparent column 15.

[0056] According to the attached Figure 7 As shown, a sealing ball 16 is provided on the inner side of the transparent column 15, and airtight gaskets 17 are provided on the inner sides of both ends of the transparent column 15 corresponding to the sealing balls 16. When the pressure relief ball 4 is squeezed with different forces, the gas inside it pushes the sealing ball 16 in the transparent column 15, causing the sealing ball 16 to move along the transparent column 15, and then the pressure of the pressure relief ball 4 is monitored through the sealing ball 16.

[0057] A decompression ring 18 is also sleeved on the side of the decompression ball 4. When the patient holds the decompression ball 4, he can also divert his attention by rotating the decompression ring 18, thereby alleviating the patient's psychological anxiety.

[0058] The intelligent brain multimodal imaging diagnosis system improves the bed used in conjunction with the existing equipment and adopts a folding bed 2 instead. The folding bed 2 provides the patient with a more comfortable experience during the examination and avoids the discomfort caused by the patient's joints squeezing the bed during a long examination. In addition, the protective side panels 203 and the airbags 3 provide boundary support for the patient to avoid the psychological pressure on the patient caused by the narrow environment. A decompression ball 4 is also provided, and the patient can hold the decompression ball 4 to divert his attention. The decompression ball 4 monitors and records the changes in the strength of the patient's fingers during the examination, and compares the inspection data of the equipment box 1 to eliminate the errors caused by the patient's emotional tension.

[0059] Furthermore, the folding bed 2 uses a fixed plate 201 as a fixed base, and a support plate 7 is extended at both ends through extension rods 6 to support the human body. The adjustment plate 202 hinged on the side of the support plate 7 is used to adjust the deflection angle to adapt to the human joints, providing a more comfortable experience for the person lying flat, avoiding the problem that the existing one-piece bed does not conform to the human body structure, easily causes pressure on the joints, and increases the patient's limb movements.

[0060] Furthermore, multiple airbags 3 are arranged from the middle of the folding bed 2 to both sides, and adjacent airbags 3 are connected by pressure valves 14 to ensure that the airbags 3 are in close contact with the patient's body, and combined with the hinged protective side panels 203, they apply a suitable amount of contact to the patient's body to soothe the patient's tension.

[0061] Furthermore, a transparent column 15 is connected between the side of the airbag 3 and the decompression ball 4. When the air pressure of the two is balanced, the change of the force exerted by the patient on the decompression ball 4 can be accurately identified through the movement of the sealing ball 16, thereby achieving effective monitoring of the patient's emotional fluctuations. By recording the movement of the sealing ball 16 in the transparent column 15 and combining it with the detection data of the equipment, the detection error caused by the patient's emotional changes is eliminated, thereby increasing the accuracy of the equipment.

[0062] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
