Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a body position adjustment device for glioma detection. Background Art

[0002] Glioblastoma is a tumor derived from glial cells in the brain. Its malignancy and growth rate vary, posing a serious threat to the life and health of patients. For the detection of glioblastoma, current research shows that genomic alterations in glioblastoma can be confirmed not only through traditional brain tissue biopsies but also through cerebrospinal fluid (CSF) tests. This discovery provides new ideas for the early diagnosis and subsequent treatment of glioblastoma.

[0003] However, for patients with glioblastoma, since the growth of the tumor is often accompanied by symptoms of intracranial hypertension, during the process of performing a lumbar puncture to obtain a CSF sample, doctors need to be extremely cautious in controlling the flow rate of CSF sampling to avoid a sudden drop in intracranial pressure due to too fast a flow rate, which may lead to serious complications such as brain herniation and intracerebral hemorrhage, causing irreversible harm to the patient. Therefore, during lumbar puncture, doctors not only need to pay attention to the puncture technique but also need to pay special attention to the body position of glioblastoma patients. An incorrect body position will directly affect the outflow rate of CSF. For example, if the patient is in an overly upright or head - elevated position, the outflow rate of CSF may increase, thus increasing the risk of a sudden drop in intracranial pressure. On the contrary, if the patient is in an overly lying - flat or head - low position, it may affect the quality and quantity of the sample due to poor CSF outflow.

[0004] Therefore, in order to ensure the safety of detection, reduce the risk of inducing complications in patients, and minimize the harm to patients to the greatest extent, it is necessary to propose a body position adjustment device for glioma detection. This device can help patients maintain a specific posture during the lumbar puncture examination of glioblastoma patients, so as to limit the flow rate of CSF to the greatest extent and improve the accuracy of detection and the comfort of patients as much as possible. Through scientific and reasonable body position adjustment, a safer and more effective detection method is provided for glioma patients, providing strong support for their subsequent treatment. Summary of the Invention

[0005] To solve the above problems, the present invention provides a body position adjustment device for glioma detection. By designing a structure that can real - time monitor the movement intention of glioblastoma patients and the degree of arching of the patient's back, and cooperating with straps with binding ability, precise adjustment and dynamic support of the body position of glioblastoma patients are achieved, so as to improve the safety of glioblastoma patients during lumbar puncture detection.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A body position adjustment device for glioma detection, including a bed board, on the surface of the bed board is fixedly connected with a support box, on the top surface of the support box is provided a strap assembly for binding and detecting the body position of a glioma patient with the binding pressure, on one side of the support box are provided a number of support plates hinged to the bed board, and the support plates are arranged corresponding to a number of strap assemblies;

[0007] On the side of each support plate close to the support box is provided a driving assembly for telescoping and pushing or pulling the support plate, the driving assemblies are all fixedly connected to the outer side wall of the support box, the output ends of the driving assemblies are all hinged to the corresponding support plates, on the side of each support plate close to the support box is provided a limiting assembly, when the driving assembly adjusts the corresponding support plate to displace, the limiting assembly dynamically adjusts the binding force of the strap assembly on the patient according to the position of the support plate, on the surface of the bed board is also fixedly connected with a pressure sensing sheet located on one side of the support box, and the pressure sensing sheet is signal-connected to a control system for controlling the body position inclination of a glioma patient according to the pressure information collected by the pressure sensing sheet;

[0008] On each strap assembly is provided a detection assembly for detecting the arching pressure on the back of a glioma patient, and a number of detection assemblies and driving assemblies are all signal-connected to the control system.

[0009] The technical principle of the above solution is as follows: With the bed board as the basic support surface, the fixedly connected support box provides a stable support platform for the whole device; the strap assembly binds the body position of the glioma patient and detects the binding pressure to ensure the stability and safety of the glioma patient during the detection process; through the telescopic movement of the driving assembly, the support plate is pushed or pulled to realize the adjustment of the body position of the glioma patient; the setting of the limiting assembly enables the binding force of the strap assembly on the glioma patient to be enhanced when the driving assembly pushes the support plate; the pressure sensing sheet can collect the pressure information generated during the body position adjustment of the glioma patient and transmit this information to the control system, and the control system calculates through an algorithm and controls the telescopic amount of the driving assembly according to the received pressure information, so as to accurately adjust the body position inclination of the glioma patient.

[0010] Adopting the above solution has the following beneficial effects:

[0011] 1. In this solution, through the ingenious design of the strap assembly and the support plate, the precise adjustment of the body position of the glioma patient is realized. Among them, the support plate, as the main support structure, can provide the necessary support force for the lumbar spine of the glioma patient according to the need to ensure its stability during the detection process, while the strap assembly further fixes the body position of the glioma patient by adjusting the binding force to prevent unnecessary movement during the detection process. Through the operations of tilting and swinging the support plate and stretching the strap assembly, medical staff can easily realize the controllable adjustment of the body position of the glioma patient to ensure the smooth progress of the detection process and improve the safety of the patient during the detection process.

[0012] 2. During the glioma detection process, the body position of glioma patients is crucial for the sampling operation of medical staff. An overly tilted body position not only affects the sampling process of medical staff, increasing the operation difficulty, but also may bring unnecessary pain to glioma patients. Therefore, this solution designs a pressure sensing sheet that can detect the center of gravity position of glioma patients lying on their sides on the bed board in real time, so as to monitor the tilting intention of glioma patients. Combining the stretching of the driving component and the tilting of the support board can ensure that glioma patients maintain the most suitable body position during the detection process, improving the sampling efficiency and ensuring the comfort of glioma patients.

[0013] 3. In the subsequent steps of glioma detection, the indwelling needle needs to wait for the sample to slowly flow out in the spinal space of glioma patients. This process requires glioma patients to maintain a certain degree of arched back to achieve higher sampling efficiency. This solution designs a detection component and a separable support board, which can monitor the arched pressure on the back of glioma patients in real time and apply different binding forces to the lumbar spine of glioma patients as needed. This design not only helps to control the arched degree of the back of glioma patients, ensuring the smooth progress of the sampling process, but also can be adjusted individually according to the individual differences of glioma patients, improving the accuracy and reliability of detection.

[0014] Furthermore, several strap assemblies are arranged symmetrically about the center of the support box, and gaps are provided between the several strap assemblies.

[0015] Beneficial effects: Since the lumbar puncture point is located at the L3-L4 vertebral space of the human body, which is a key part during medical operations such as glioma detection. Therefore, during the body position adjustment process, it is necessary to ensure that both sides of this part are fully supported and fixed to avoid displacement during the operation and affect the smooth progress of sampling. At the same time, gaps are provided between the strap assemblies on both sides to provide additional operating space for the lumbar puncture point, enabling medical staff to adjust the body position of glioma patients more flexibly during operations such as lumbar puncture, ensuring that the puncture needle can accurately reach the target position. In addition, the setting of the gaps also helps to reduce the direct pressure of the strap assemblies on the skin of glioma patients and reduce the discomfort caused by lying down for a long time.

[0016] Furthermore, the strap assembly includes several rope receiving grooves opened on the top surface of the support box. Elastic first straps are provided in the rope receiving grooves. Rope receiving grooves corresponding to the rope receiving grooves are opened on the surface of the bed board. Elastic second straps are fixedly connected in the rope receiving grooves. A rope receiving buckle is sleeved on the second strap, and the first strap is detachably connected to the second strap through the rope receiving buckle.

[0017] Beneficial effects: Through the combined use of the first strap and the second strap, as well as the adjustment function of the drawstring buckle, medical staff can flexibly adjust the restraint force of the straps according to the body shape, posture requirements of glioma patients, and specific requirements during the detection process, ensuring that glioma patients can maintain a stable body position during the detection process and avoid discomfort caused by excessive restraint. In addition, the first strap and the second strap are detachably connected through the drawstring buckle, and this design makes the installation and disassembly of the straps very simple and fast. When it is necessary to adjust the body position of glioma patients or perform other operations, medical staff can quickly untie the straps and then refix them according to needs, improving the convenience of body position adjustment and shortening the unnecessary time consumption during the detection process.

[0018] Further, the limiting component includes a plurality of telescopic cavities corresponding to the rope receiving grooves opened in the support box. The telescopic cavities are all located below the corresponding rope receiving grooves, and the telescopic cavities are all communicated with the corresponding rope receiving grooves. One end of the first strap extends into the telescopic cavity through the rope receiving groove and is fixedly connected to the corresponding connecting rod.

[0019] Beneficial effects: When the driving component pushes the support plate to move, due to the hinged relationship between the connecting rod and the support plate and the fixed connection between the first strap and the connecting rod, the movement of the support plate will drive the connecting rod to slide in the telescopic cavity, and then generate corresponding restraint or release force on the body position of the glioma patient through the first strap, ensuring that during the body position adjustment process, the support plate and the strap assembly can work together to jointly achieve precise control of the body position of the glioma patient. In addition, as the support plate moves, the sliding of the connecting rod in the telescopic cavity will real-time change the tension degree of the first strap, thereby realizing the dynamic adjustment of the restraint force on the glioma patient, enabling the device to automatically adjust the restraint force according to the body shape, posture change of the glioma patient, and detection requirements, ensuring that the glioma patient maintains a stable body position during the detection process and reducing discomfort at the same time.

[0020] Further, the detection component includes a plurality of pressure sensors fixedly connected to the surface of the second strap, and the plurality of pressure sensors are all signal-connected to the control system.

[0021] Beneficial effects: The pressure sensors can real-time monitor the pressure distribution of the second strap on the body of the glioma patient, ensuring that the strap provides necessary support without causing excessive pressure or discomfort to the glioma patient. Once the pressure sensors detect abnormal pressure distribution or pressure values exceeding the preset range, it will immediately feedback the signal to the control system, enabling medical staff to quickly respond and adjust the body position of the glioma patient or the tightness of the strap.

[0022] Furthermore, an air pillow is provided on one side of the support box. The air pillow includes an upper pad and a lower pad. The lower pad is fixedly connected to the bed board. One side of the upper pad close to the support box is hinged to the lower pad, and an airbag is fixedly connected between the upper pad and the lower pad.

[0023] Beneficial effects: Through its adjustable airbag design, the air pillow can provide personalized head and neck support according to the body shape, height of glioma patients and their specific needs when lying down, which helps to reduce the discomfort of glioma patients during long-term examinations and improve the overall comfort.

[0024] Furthermore, a number of negative pressure cavities corresponding to the telescopic cavities are also opened in the support box. The ends of the connecting rods far from the support plate all penetrate the inner wall of the telescopic cavity and extend into the negative pressure cavity, and a piston is fixedly connected to the end of the connecting rod far from the support plate. The piston fits the inner wall of the negative pressure cavity and is slidably matched with the negative pressure cavity. The negative pressure cavity is communicated with the airbag, and the communication part is located on the side of the negative pressure cavity close to the telescopic cavity.

[0025] Beneficial effects: When the support plate starts to tilt under the drive of the drive component, the connecting rod will move accordingly and drive the piston to slide in the negative pressure cavity. This movement process will compress the gas in the negative pressure cavity, causing it to flow into the airbag, resulting in the inflation of the airbag. As the airbag inflates, the upper pad will gradually lift relative to the lower pad, simulating the effect of raising the head of the bed. This process is automated and does not require manual operation by medical staff, thus improving the efficiency and convenience of the examination process. The automatic and stable raising of the head of the bed helps glioma patients to maintain a more comfortable position when lying down. Especially after a long-term examination, this automatic head-of-bed adjustment function can reduce the discomfort of glioma patients and improve the overall comfort.

[0026] Furthermore, the control system includes a pressure distribution acquisition module, a centroid calculation module, a pressure data acquisition module, an arch degree calculation module and a drive module;

[0027] The pressure distribution acquisition module is used to collect the pressure magnitude, distribution position and change trend of the contact surface between the body of the glioma patient and the bed board through pressure sensing sheets;

[0028] The centroid calculation module is used to perform denoising and smoothing processing operations on the data received from the pressure distribution acquisition module, and then use the "centroid algorithm" to simulate and calculate the centroid position of the glioma patient, and compare and judge whether the centroid position deviates from the distribution range of the pressure data. If the centroid position deviates towards the support box side, the first drive information is sent to the drive module. Otherwise, the centroid calculation module sends the second drive information to the drive module;

[0029] The pressure data acquisition module is used to collect and record the data of each pressure sensor on the second strap and number each pressure sensor;

[0030] The arch degree calculation module is used to compare adjacent pressure data according to the data provided by the pressure data acquisition module. When the pressure data closer to the origin is less than the pressure data farther from the origin, the third drive information is sent to the drive module.

[0031] The drive module is used to send drive signals to the drive components according to the drive signals sent by the center of gravity calculation module and the arch degree calculation module. When the drive module receives the first drive information, the drive module sends drive signals to the drive components to make each support plate swing towards the side away from the support box. When the drive module receives the second drive information, the drive module sends drive signals to the drive components to make each support plate swing towards the side close to the support box.

[0032] Beneficial effects: Through the pressure distribution acquisition module, the system can monitor the pressure magnitude, distribution position and change trend of the contact surface between the body of glioma patients and the bed board in real time, providing an accurate data basis for the center of gravity calculation module, enabling the system to quickly judge the center of gravity position of glioma patients, and realizing precise adjustment of the body position of glioma patients through the drive module, ensuring the stability and safety of glioma patients during the detection process; According to the judgment result, the center of gravity calculation module can intelligently send drive signals for supporting or tightening the body of glioma patients to the drive module, improving the accuracy and efficiency of adjustment, reducing the manual intervention of medical staff, and reducing the operation difficulty; The pressure data acquisition module can collect and record the data of each pressure sensor located on the second strap and number each pressure sensor. This enables the system to make personalized adjustments to the tightness of the strap according to the body shape and posture changes of glioma patients. By comparing adjacent pressure data through the arch degree calculation module, the system can accurately judge the arch degree of the back of glioma patients and send corresponding drive signals to the drive module to achieve dynamic support and precise control of the body position of glioma patients.

[0033] Furthermore, in the center of gravity calculation module, after denoising and smoothing the data, the mass of each mass unit is obtained by multiplying the pressure by the product of the pressure distribution area and the elastic coefficient. Then, using the mass of each mass unit and the coordinates of the corresponding mass unit on the bed board, the real-time center of gravity coordinates of glioma patients are calculated by means of weighted summation.

[0034] Beneficial effects: The center of gravity calculation module can more accurately reflect the pressure distribution of various parts of the body of glioma patients on the bed board, thereby more accurately calculating the real-time center of gravity coordinates of glioma patients. After obtaining the real-time center of gravity coordinates of glioma patients, the control system can quickly determine whether the body position of glioma patients has shifted, and accordingly adjust the inclination of the support plate and the binding force of the binding component through the driving component, realizing dynamic adjustment of the body position of glioma patients, which helps to ensure that glioma patients maintain a stable body position during the detection process and reduce detection errors caused by body position changes.

[0035] Further, in the pressure data acquisition module, for the pressure sensors, according to the distribution of each pressure sensor on the corresponding second binding band, taking the position symmetric about the center of several pressure sensors as the origin, the pressure sensors on both sides of the origin are numbered in the form of 'r i ' and 'l j ', where i and j increase according to the distance between the pressure sensors on the same side and the origin;

[0036] When the pressure data detected by the r i pressure sensor is less than the pressure data detected by the r i+1 pressure sensor or the pressure data detected by the l j pressure sensor is less than the pressure data detected by the l j+1 pressure sensor, the third driving information containing the numbered data of i + 1 or j + 1 is transmitted to the driving module. When the driving module receives the third driving information, it sends a driving signal to the driving component to drive the corresponding support plate numbered i + 1 or j + 1 to swing towards the side close to the support box.

[0037] Beneficial effects: Through the numbering system, each pressure sensor's data is assigned a unique identifier. This helps to quickly identify and locate specific data points during the data processing process, thereby improving data processing efficiency. The numbering system makes the data relationship between adjacent pressure sensors clearer. For example, by comparing the adjacent numbered pressure data, it is easier to identify the change trend and abnormal points of the pressure distribution, which helps to simplify the data analysis process and improve the accuracy of the analysis.

[0047] The following is a further detailed description through specific embodiments:

[0048] Embodiment 1:

[0049] As shown in the attached Figure 1 and Figure 2As shown: A body position adjustment device for glioma detection, including a bed board 1. A support box 2 is welded on the surface of the bed board 1. A number of rope receiving grooves 5 are opened on the top surface of the support box 2. Elastic first straps 6 are wound in the rope receiving grooves 5 respectively. Correspondingly, a number of rope storage grooves 7 corresponding to the rope receiving grooves 5 are opened on the surface of the bed board 1. Second straps 8 are fixedly connected in the rope storage grooves 7 by screws respectively. A rope receiving buckle 9 is sleeved on the second strap 8. The first strap 6 and the second strap 8 are connected by the rope receiving buckle 9, so that the first strap 6 and the second strap 8 can achieve variable-area restraint; Since the lumbar puncture detection process requires the glioma patient to lie on the side on the bed board 1, remove the pillow, align the back with the edge of the bed, bend the head towards the chest, hold the knees with both hands, bend the knees towards the abdomen, and arch the waist and back as much as possible to widen the intervertebral space, which is beneficial for puncture; Since the lumbar puncture point is located at the L3-L4 vertebral interspace of the human body, due to the design of the support box 2, the first strap 6 and the second strap 8, the support box 2 provides support for the abdomen of the glioma patient (the front corresponding to the L3-L4 vertebral interspace of the human body), ensuring the stability of the abdomen of the glioma patient during the detection process. The first strap 6 and the second strap 8 exert a restraining force on the waist of the glioma patient, firmly restraining the waist of the glioma patient, and preventing the glioma patient from moving during the detection process.

[0050] Since long-term fixed restraint (i.e., straps made of rigid materials) will cause discomfort to glioma patients, and even cause harm to glioma patients, resulting in a resistant mood in patients and increasing the detection risk. Therefore, the elastic first strap 6 and second strap 8 can effectively improve the comfort of glioma patients during the puncture sampling process, relieve the discomfort and potential harm caused by long-term fixed restraint, and also ensure the psychological relaxation of glioma patients during the detection process, which is beneficial to reducing the impact of tension on the detection results; Correspondingly, elastic restraint will reduce the restriction on the body position of glioma patients. During the puncture process, the unfixed lumbar position of glioma patients will affect the sampling process of medical staff. For this reason, the control of the inclination of the waist of glioma patients is designed. A number of parallel support plates 3 are provided on the side of the support box 2 close to the second strap 8. The positions of the number of support plates 3 correspond to the positions of the number of first straps 6 one by one. A pressure sensing sheet 4 is fixedly connected to the surface of the bed board 1 by screws. The pressure sensing sheet 4 is located between the support box 2 and the second strap 8. The pressure sensing sheet 4 is signal-connected to a control system. The pressure sensing sheet 4 is designed to detect the pressure magnitude and pressure distribution of the contact surface between the glioma patient lying on the side and the bed board 1, so as to identify the turning tendency of the glioma patient.

[0051] For the position adjustment of glioma patients after they have a tendency to turn over, a gap is provided between the support plate 3 and the support box 2. The bottom end of the support plate 3 is hinged to the bed board 1. A number of electric cylinders corresponding to the first straps 6 are embedded in the side wall of the support box 2 close to the support plate 3. The output shafts of the electric cylinders are all hinged to the support plate 3. When the output shafts of the electric cylinders extend, the support plate 3 tilts and swings towards the direction close to the second strap 8. On the contrary, the support plate 3 tilts and swings towards the direction close to the support box 2. Utilizing this movement trend, a number of telescopic cavities 10 corresponding to the number and positions of the rope receiving grooves 5 are also provided in the support box 2. The telescopic cavities 10 are all located below the corresponding rope receiving grooves 5. A number of connecting rods 11 corresponding to the telescopic cavities 10 are hinged to the side of the support plate 3 close to the support box 2. The telescopic cavities 10 are all communicated with the corresponding rope receiving grooves 5. One end of the first strap 6 extends into the telescopic cavity 10 through the rope receiving groove 5 and is fixedly connected to the corresponding connecting rod 11 by screws. Taking any one of the telescopic cavities 10 as an example to illustrate in combination with the swinging trend of the support plate 3, when the support plate 3 tilts and swings away from the support box 2, the connecting rod 11 follows the swing of the support plate 3 and shows a movement trend away from the telescopic cavity 10, and the corresponding first strap 6 shows an effect of elongation and relaxation of restraint. On the contrary, when the support plate 3 tilts and swings towards the support box 2, the first strap 6 will show an effect of contraction and tightening of restraint. Combining with the monitoring of the turning-over trend by the pressure sensing sheet 4, that is, when the pressure sensing sheet 4 monitors that the body of the glioma patient has an inclined turning-over close to the support box 2, the control system sends a signal to drive the electric cylinder to extend the output shaft. The support plate 3 provides a supporting force for the body of the glioma patient. At the same time, the first strap 6 relaxes (the restraint between the first strap 6 and the second strap 8 is reduced). On the contrary, when the pressure sensing sheet 4 monitors that the body of the glioma patient has an inclined turning-over away from the support box 2, the control system sends a signal to drive the electric cylinder to shorten the output shaft. The support plate 3 tilts and swings inwards. At the same time, the first strap 6 tightens (the restraint between the first strap 6 and the second strap 8 is tightened), realizing the precise adjustment and dynamic support of the position of the glioma patient, reducing the sampling error and potential risks caused by the involuntary movement of the glioma patient, strengthening the effect of the position adjustment of the glioma patient, reducing the influence of the glioma patient on the sampling operation due to pain or other reasons, improving the safety and efficiency of the lumbar puncture detection, and providing a more comfortable, safe and efficient detection experience for the glioma patient.

[0052] In addition, since the optimal body position for lumbar puncture sampling requires glioma patients to arch their backs as much as possible backward to widen the intervertebral space, and due to the corresponding separated design of several support plates 3, several second straps 8 are each fixedly connected with a pressure sensor 12 on the surface through screws, and several pressure sensors 12 are all in signal connection with the control system; through the pressure acquisition of several pressure sensors 12, the restraint pressure near the L3-4 intervertebral space (near the center of the support box 2) and the restraint pressure far from the L3-4 intervertebral space (far from the center of the support box 2) can be respectively collected. By comparing the two restraint pressures, when the pressure data far from the center of the support box 2 is greater than the pressure data near the center of the support box 2, it indicates that the glioma patient has a tendency to stretch. At this time, it is not conducive to the sampling process, so the electro-cylinder corresponding to the far side of the support center is controlled to shorten, that is, the restraint force of the corresponding first strap 6 and second strap 8 is enhanced to slow down the stretching tendency of the glioma patient, so as to control the degree of the glioma patient's back arching backward, and reduce the impact on the subsequent drainage of the spinal cord sample due to insufficient arching of the back.

[0053] Example 2:

[0054] As shown in the appendix Figure 2 and Figure 3As shown in the figure, the difference from Example 1 is that after puncture sampling, conventional glioma patients need to lie flat on their backs without a pillow for 4 to 6 hours, but glioma patients need to take different measures due to their special nature. First of all, due to the effect of gravity, gastric juice in glioma patients is not easily refluxed, and if vomiting occurs due to anesthetic or central reasons, raising the head of the bed facilitates the discharge of vomit and prevents asphyxiation. Secondly, raising the head of the bed is beneficial to the intracranial venous return, reduces intracranial pressure, and alleviates headache. Since there are no valves in the intracranial venous system, when the head is in a high position, the venous pressure decreases, the venous blood return accelerates, the intracranial blood volume and cerebral blood flow are reduced (temporarily reduced by 20%), which is conducive to the recovery of glioma patients. Therefore, an air pillow 13 is provided on one side of the support box 2. The air pillow 13 includes an upper pad 14 and a lower pad 15. The bottom of the lower pad 15 is fixedly connected to the top of the bed board 1 through screws. One side of the upper pad 14 close to the support box 2 is hinged to the lower pad 15. An airbag 16 is fixedly connected between the upper pad 14 and the lower pad 15 through a buckle structure. A plurality of negative pressure chambers 17 corresponding to the telescopic chambers 10 are also opened in the support box 2. One end of the connecting rod 11 away from the support plate 3 penetrates the inner wall of the telescopic chamber 10 and extends into the negative pressure chamber 17, and a piston 18 is fixedly connected to one end of the connecting rod 11 away from the support plate 3. The piston 18 fits the inner wall of the negative pressure chamber 17 and is slidably matched with the negative pressure chamber 17. The negative pressure chamber 17 is communicated with the airbag 16, and the communication part is located on the side of the negative pressure chamber 17 close to the telescopic chamber 10. When the support plate 3 starts to tilt under the drive of the electric control cylinder, the glioma patient gradually lies down smoothly. The connecting rod 11 moves along with the tilt of the support plate 3, and the piston 18 starts to slide along the inner wall of the negative pressure chamber 17. As the connecting rod 11 slides, the piston 18 applies pressure to the gas in the negative pressure chamber 17, causing the gas to be compressed and flow into the airbag 16. After receiving the gas from the negative pressure chamber 17, the airbag 16 starts to expand. The expansion process increases the volume of the airbag 16 and also makes the upper pad 14 gradually lift relative to the lower pad 15, thus simulating the effect of raising the head of the bed, realizing the function of automatically and smoothly raising the head of the bed while the glioma patient lies down, improving the comfort of glioma patients, simplifying the medical care process, and providing convenience for medical staff.

[0055] Example 3:

[0056] As shown in the attached Figure 4 figure, the difference from Example 2 is that the control system includes a pressure distribution acquisition module, a center of gravity calculation module, a pressure data acquisition module, an arch degree calculation module, and a drive module;

[0057] The pressure distribution acquisition module collects the pressure magnitude, distribution position, and change trend of the contact surface between the body of the glioma patient and the bed board 1 through the pressure sensing sheet 4.

[0058] After receiving the data from the pressure distribution acquisition module, the center of gravity calculation module first performs denoising and smoothing processing on the data to eliminate random fluctuations and noise interference in the data and ensure the accuracy of subsequent calculations. Subsequently, the module calculates the mass of each mass unit by using the product relationship between pressure, pressure distribution area, and elastic coefficient. On this basis, the module further uses the mass of each mass unit and the coordinate information of the corresponding mass unit on the bed board 1 to accurately calculate the real-time center of gravity coordinates of the glioma patient by means of weighted summation. By comparing and judging whether the center of gravity position deviates from the distribution range of the pressure data, the module can evaluate the postural stability of the glioma patient in real time and send corresponding driving information to the driving module when necessary. That is, when the center of gravity position deviates towards one side of the support box 2, the first driving information is sent to the driving module. On the contrary, the center of gravity calculation module sends the second driving information to the driving module to achieve precise adjustment of the posture of the glioma patient.

[0059] The pressure data acquisition module is mainly responsible for collecting and recording the data of each pressure sensor 12 located on the second strap 8. To ensure the accuracy and traceability of the data, the module numbers each pressure sensor 12 and manages them in an orderly manner according to the distribution of each pressure sensor 12 on the corresponding second strap 8. The numbering method uses the position symmetric to the center of several pressure sensors 12 as the origin, and the pressure sensors 12 on both sides of the origin are numbered in the form of 'r i ' and 'l j ', where i and j increase according to the distance between the pressure sensors 12 on the same side and the origin. That is, as shown in the layout of the support plate 3 in Figure 1 , the pressure sensors 12 inside it are r2, r1, l1, and l2 from left to right. This numbering method not only facilitates data management and analysis but also effectively reflects the relative position relationship between the pressure sensors 12. By collecting and recording these data in real time, the pressure data acquisition module provides rich data support for the arch degree calculation module and the center of gravity calculation module.

[0060] The arch degree calculation module mainly compares and analyzes adjacent pressure data based on the data provided by the pressure data acquisition module. When it is found that the pressure data near the origin is less than the pressure data far from the origin, for example, when the pressure data of the r1 pressure sensor 12 is less than the pressure data of the r2 pressure sensor 12, this module will judge that there may be an arch phenomenon in the back and waist and other parts of the glioma patient, and thus transmit the third drive signal containing the r2 numbered data to the drive module. In order to correct this abnormal body position, the arch degree calculation module will send a corresponding drive signal to the drive module, requiring the second strap 8 at r2 far from the origin to be tightened, so as to realize the dynamic adjustment of the body position of the glioma patient. This adjustment method not only helps to keep the body position of the glioma patient stable, but also effectively reduces the discomfort caused by improper body position.

[0061] The drive module is the actuator in the body position adjustment device for glioma detection, and is mainly responsible for according to the drive signals sent by the center of gravity calculation module and the arch degree calculation module. When the drive module receives the first drive information, the drive module sends drive signals to each electric control cylinder, so that each support plate 3 swings towards the side away from the support box 2, and when the drive module receives the second drive information, the drive module sends drive signals to each electric control cylinder, so that each support plate 3 swings towards the side close to the support box 2;

[0062] And when the drive module receives the third drive information, it sends a drive signal to the drive component, driving the corresponding r i+1 or l j+1 numbered support plate 3 to swing towards the side close to the support box 2, that is, controlling the r i+1 or l j+1 numbered electric control cylinder to start. These electric control cylinders are connected to the bed board 1 and the second strap 8 through mechanisms such as the connecting rod 11, and can realize the precise adjustment of the body position of the glioma patient. In order to ensure the accuracy and stability of the adjustment, the drive module is also equipped with advanced control algorithms and sensor feedback mechanisms, which can monitor and adjust the motion state of the electric control cylinder in real time, so as to realize the continuous and stable control of the body position of the glioma patient.

[0063] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
