Description

Technical Field

[0001] The invention relates to the technical field of medicine, in particular to a child inspection and fixing device used for medical image scanning. Background Art

[0002] The Radiology Department is an important auxiliary examination department in the hospital. In the construction of modern hospitals, the Radiology Department is a department that integrates examination, diagnosis and treatment. Many diseases in various clinical departments must be examined by medical imaging equipment in the Radiology Department to achieve clear diagnosis and auxiliary diagnosis; but when examining children in the Pediatric Department, medical imaging equipment is also needed to examine the children, so that the children can lie flat on the examination bed for physical examination, which is convenient for doctors to better understand their physical condition or illness;

[0003] Prior art CN114587400A discloses an imaging examination bed for children. The technical solution discloses that "the patient's body is squeezed toward the bed board by a fixing belt, and the restraining plate is also pressed against the patient under the action of the fixing belt. The restraining plate includes a connecting portion and a side stop portion. The connecting portion is pressed against the patient, and the side stop portions are located on both sides of the patient. When the tensioning belt adjusts the distance between the two restraining plates, the side stop portions can stop the side of the patient. When the child is in use, it can reduce the child's movement to one side during the imaging examination; 2. By cross-arranging the tensioning belts, when the two tensioning belts are tightened toward the two sides of the bed board, the two restraining plates are brought closer to the middle, so that the patient can move to one side when the child is in use; 3. By cross-arranging the tensioning belts, when the two tensioning belts are tightened toward the two sides of the bed board, the two restraining plates are brought closer to the middle, so that the patient can move to one side when the child is in use; 4. By cross-arranging the tensioning belts, when the two tensioning belts are tightened toward the two sides of the bed board, the two restraining plates are brought closer to the middle, so that the patient can move to one side when the child is in use; 5. By cross-arranging the tensioning belts, when the two tensioning belts are tightened toward the two sides of the bed board, the patient can move to one side when the child is in use; 6. By cross-arranging the tensioning belts, the patient's body is squeezed toward the bed board, and the restraining plate can move to the other side when the child is in use; 7. 3. The rotating shaft on one side of the bed plate rotates, and the rotating shaft on the other side is driven by the transmission belt, so that the winding wheel installed on the rotating shaft rotates synchronously, and the two ends of the fixing belt are wound up at the same time under the action of the two winding wheels, so that the fixing belt and the tensioning belt restrict the patient in the middle position of the bed plate. "Although a pediatric imaging examination bed has achieved the function of fixing children during pediatric imaging examinations, the method of fixing by the tensioning belt and the restraint plate always has a certain squeezing force for children, which makes children feel uncomfortable, and then causes children to make noises, which will interfere with the efficiency of imaging examinations.

[0004] In addition, existing medical imaging equipment usually only considers adult examinations, thus ignoring the problems that children may encounter during the examination process. For example, children's bodies may move and shake during the examination, making it impossible to make an accurate diagnosis in the final test results, which in turn affects the diagnosis results. If the examination is performed with an adult accompanying the child, it may also interfere with the test results. Summary of the invention

[0005] The object of the present invention is to provide a child inspection and fixation device for medical image scanning to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A child examination and fixation device for medical image scanning comprises: a fixed platform, an examination bed is arranged on the top of the fixed platform, a depression is arranged on the surface of the examination bed, a restraint device is arranged on one side of the examination bed, the restraint device is rotatably connected to the examination bed, the restraint device is composed of a plurality of restraint groups, and the plurality of restraint groups are equidistantly arranged along the side of the examination bed, and a lifting device is arranged between the fixed platform and the examination bed.

[0008] Preferably, the restraint group consists of a rotating plate and a water bag cavity, the rotating plate is arc-shaped, the water bag cavity is arranged on a side of the rotating plate close to the examination bed, a rotating shaft is arranged on the side wall of the examination bed, and the rotating plate is rotatably connected to the examination bed via the rotating shaft.

[0009] Preferably, an expansion plate is provided on a side close to the recessed head, the inner diameter of the expansion plate is larger than the outer diameter of the rotating plate, and a fixed cavity is provided on a side of the expansion plate close to the examination bed.

[0010] Preferably, a water storage chamber is provided inside the examination bed, and a plurality of stretching tubes are provided on the side of the water storage chamber close to the rotating plate, one end of the stretching tube is connected to the water storage chamber, a heating wire and a water pump are provided in the water storage chamber, and the water pump is connected to the stretching tube through a pipeline, and flow channels are provided in both the rotating plate and the expansion plate, one end of the flow channel is connected to the stretching tube, the other end of the flow channel in the rotating plate is connected to the water bag chamber, and the other end of the flow channel in the expansion plate is connected to the fixed chamber.

[0011] Preferably, a pipeline is provided between two adjacent rotating plates for communication, and a pipeline is provided between the expansion plate and the adjacent rotating plate for communication.

[0012] Preferably, the water bag cavity is made of a transparent rubber material, and the fixing cavity is made of a transparent acrylic plate.

[0013] Preferably, a theme patch is provided on one side of the rotating plate and the expansion plate close to the examination bed, and the theme patch is an ocean theme.

[0014] Preferably, a plurality of models are placed in the water sac cavity and the fixed cavity, and the models are marine organism models.

[0015] Preferably, the rotating plate and the expansion plate are made of anti-magnetic carbon fiber material.

[0016] Preferably, each of the restraining groups can rotate around the rotating axis independently.

[0017] Preferably, the lifting device comprises: a lifting cavity, the examination bed extends into the lifting cavity, a plurality of racks are arranged on the side wall of the examination bed, a motor is arranged in the lifting cavity, a gear is arranged on the driving shaft of the motor, the gear corresponds to the rack one by one, and the gear and the rack are meshed for transmission. When the child needs to sit on the examination bed, the controller controls the motor to start, and the driving shaft of the motor immediately drives the gear to rotate, and the gear meshes with the rack on the side wall of the examination bed during the rotation process, thereby driving the examination bed to move, and the examination bed immediately moves to the side close to the lifting cavity, and then the bottom of the examination bed shrinks into the lifting cavity, so that the examination bed descends and reaches a height that the child can sit on, avoiding the problem that the child needs to climb onto the examination bed and fall off; when the child sits on the examination bed, the controller controls the motor to rotate in the reverse direction, and the driving shaft of the motor drives the gear to rotate in the reverse direction, and then the examination bed is lifted under the rotation of the gear, so that the examination bed moves to the side away from the lifting cavity, so that the examination bed drives the child to approach the medical imaging equipment, and when the examination bed moves to the highest point of the stroke, the motor stops.

[0018] After the child enters the medical imaging room, he / she first sits on the examination bed, and then the child lies flat in the depression under the guidance of the medical staff, which restricts the back of the child. Then the medical staff rotates the restraint group corresponding to the part not to be imaged according to the part to be imaged. The medical staff rotates the rotating plate and the extension plate around the rotating shaft in turn by manual rotation, so that the rotating plate and the extension plate rotate to the top of the examination bed;

[0019] The rotating plate and the extension plate are both made of anti-magnetic carbon fiber material, so that when medical imaging is being performed, the anti-magnetic carbon fiber material can block the radiation emitted by the medical imaging device, so that the influence of the radiation emitted by the medical imaging device on the parts that do not need to be photographed is reduced, thereby preventing children from being exposed to more radiation, thereby improving the safety of medical imaging detection for children;

[0020] During the rotation of the rotating plate and the extension plate, the rotating plate drives the water bag cavity to rotate, while the extension plate drives the fixed cavity to rotate. Since the inner diameter of the extension plate is larger than the outer diameter of the rotating plate, when the extension plate and the rotating plate rotate to the top of the examination bed, the distance between the extension plate and the examination bed is larger than the distance between the rotating plate and the examination bed, and the extension plate releases the head space of the child, so that the child will not be squeezed and cry;

[0021] At the same time, after the rotating plate drives the water bladder cavity to rotate, the water bladder cavity is made of transparent rubber material, so the water bladder cavity will be located above the child's body on the side of the chest away from the examination bed. When the child is lying flat, the medical staff controls the heating wire in the water storage cavity to start through the controller, and the heating wire heats the water in the water storage cavity. When the rotating plate and the expansion plate are rotated into place, the water pump is controlled to start through the controller. The water pump transports the water in the water storage cavity through the pipeline to the stretching tube. The heated warm water is then transported to the water bladder cavity and the fixed cavity through the stretching tube. When the warm water is transported to the water bladder cavity, the gravity of the warm water on the water bladder cavity rises due to the continuous injection of warm water, and the water bladder cavity moves under the influence of the gravity of the warm water. The water bag cavity moves toward the side close to the examination bed, and during the movement of the water bag cavity, it fits and wraps the child's body on the side of the chest away from the examination bed, and then the water bag cavity cooperates with the depression to fix the child's body, and then the child's body is limited by the gravity of the water. Compared with the traditional method of fixing and restraining by straps, the water bag cavity is driven by the gravity of the water to move, and cooperates with the depression to fit and wrap the child, which will not produce the tightening feeling caused by the straps, and then the child will have a better experience when undergoing medical imaging examinations, avoiding the phenomenon of children crying due to the restraint caused by the straps, thereby shortening the time for children to undergo medical imaging examinations and improving the efficiency of children's medical imaging examinations;

[0022] Since the rotating plate and the expansion plate are provided with theme patches on the side close to the examination bed, and the theme patches are preferably marine-themed, and several models are placed in the water bag cavity and the fixed cavity, and the models are preferably marine life models, when warm water is injected into the fixed cavity, the warm water will impact the models in the fixed cavity, and then the marine life models in the fixed cavity will move under the action of the warm water, and the fixed cavity is provided with marine-themed patches, which can attract children's attention, thereby reducing children's fear of the instrument, better cooperating in completing medical imaging examinations, and further improving the efficiency of medical imaging examinations for children;

[0023] And due to the restraint of the water sac cavity and the depression, children may make slight movements of their hands, feet or bodies, and the force generated by the slight movement of the body will be fed back to the water sac cavity, causing the water in the water sac cavity to generate flow force. Since the water sac cavity and the fixed cavity are connected by a pipe, water will flow in the water sac cavity and the fixed cavity through the pipe, and the flow of water will drive the marine life model in the fixed cavity to move, which will create a feeling of being in the ocean in front of the children, making the children forget the illusion that they are undergoing a medical imaging examination, thereby eliminating the children's fear of medical equipment and the absence of adults, and further enabling the children to cooperate with medical staff to complete the medical imaging examination.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. Both the rotating plate and the extension plate are made of anti-magnetic carbon fiber material. When taking medical images, the anti-magnetic carbon fiber material can weaken the radiation emitted by the medical imaging equipment, thereby reducing the impact of the radiation emitted by the medical imaging equipment on parts that do not need to be photographed, thereby avoiding children from being exposed to more radiation, thereby improving the safety of medical imaging tests for children.

[0026] 2. After the warm water is delivered to the water sac cavity, the gravity of the warm water on the water sac cavity increases due to the continuous injection of warm water, and the water sac cavity moves under the influence of the gravity of the warm water, and moves to the side close to the examination bed. During the movement of the water sac cavity, the child's body is wrapped closely to the chest of the child away from the examination bed, and the water sac cavity cooperates with the depression to fix the child's body, and the child's body is limited by the gravity of the water. Compared with the traditional method of fixing and restraining with straps, the water sac cavity is driven to move by the gravity of the water, and cooperates with the depression to wrap the child closely, without the tightening feeling caused by the straps, and the child's experience during medical imaging examinations will be better, avoiding the phenomenon of children crying due to the restraint caused by the straps, thereby shortening the time for children to undergo medical imaging examinations and improving the efficiency of children's medical imaging examinations.

[0027] 3. When warm water is injected into the fixed cavity, the warm water will impact the model in the fixed cavity, and then the marine life model in the fixed cavity will move under the action of the warm water. Combined with the marine subject patch set in the fixed cavity, the children's attention can be attracted, thereby reducing the children's fear of the instrument, better cooperating in completing medical imaging examinations, and further improving the efficiency of medical imaging examinations for children.

[0050] Working principle of the present invention:

[0051] After the child enters the medical imaging room, when the child needs to sit on the examination bed 11, the controller controls the motor to start, and the drive shaft of the motor immediately drives the gear to rotate. During the rotation of the gear, it engages with the rack 32 on the side wall of the examination bed 11, thereby driving the examination bed 11 to move. The examination bed 11 immediately moves to the side close to the lifting cavity 31, and then the bottom of the examination bed 11 shrinks into the lifting cavity 31, so that the examination bed 11 descends and reaches a height that the child can sit on, avoiding the problem of the child needing to climb onto the examination bed 11 and causing falling injuries; when the child sits on the examination bed 11, the controller controls the motor to rotate in the opposite direction, and the drive shaft of the motor drives the gear to rotate in the opposite direction, and then the examination bed 11 is lifted under the rotation of the gear, so that the examination bed 11 moves to the side away from the lifting cavity 31, so that the examination bed 11 drives the child to approach the medical imaging equipment, and when the examination bed 11 moves to the highest point of the stroke, the motor stops.

[0052] The child lies flat in the depression 12 under the guidance of the medical staff, and the depression 12 restricts the back of the child. Then the medical staff rotates the restraint group 21 corresponding to the part not to be imaged according to the part to be imaged. The medical staff rotates the rotating plate 22 and the extension plate 24 around the rotating shaft in sequence by manual rotation, so that the rotating plate 22 and the extension plate 24 are rotated to the top of the examination bed 11;

[0053] The rotating plate 22 and the extension plate 24 are both made of anti-magnetic carbon fiber material, and the rotating plate 22 and the extension plate 24 are grounded through the examination bed 11, so that when medical imaging is performed, the anti-magnetic carbon fiber material can weaken the radiation emitted by the medical imaging device, so that the influence of the radiation emitted by the medical imaging device on the parts that do not need to be photographed is reduced, thereby preventing children from being exposed to more radiation, thereby improving the safety of medical imaging detection for children;

[0054] During the rotation of the rotating plate 22 and the expansion plate 24, the rotating plate 22 drives the water bag chamber 23 to rotate, and the expansion plate 24 drives the fixed chamber 25 to rotate. Since the inner diameter of the expansion plate 24 is larger than the outer diameter of the rotating plate 22, when the expansion plate 24 and the rotating plate 22 rotate to the top of the examination bed 11, the distance between the expansion plate 24 and the examination bed 11 is larger than the distance between the rotating plate 22 and the examination bed 11, and the expansion plate 24 leaves space for the child's head, so that the child will not be squeezed and cry;

[0055] At the same time, after the rotating plate 22 drives the water bag chamber 23 to rotate, the water bag chamber 23 is made of transparent rubber material, so the water bag chamber 23 will be located above the child's chest away from the examination bed 11. When the child lies flat, the medical staff controls the heating wire in the water storage chamber 13 to start through the controller, and the heating wire heats the water in the water storage chamber 13. When the rotating plate 22 and the expansion plate 24 are rotated to the right position, the water pump is controlled to start through the controller. The water pump transports the water in the water storage chamber 13 to the stretch tube 14 through the pipeline. The warm water formed by heating is then transported to the water bag chamber 23 and the fixed chamber 25 through the stretch tube 14. After the warm water is transported to the water bag chamber 23, due to the continuous injection of warm water, the gravity of the warm water on the water bag chamber 23 also rises accordingly. Then, the water bag cavity 23 moves under the influence of the gravity of the warm water, and the water bag cavity 23 moves to the side close to the examination bed 11. During the movement of the water bag cavity 23, the water bag cavity 23 fits and wraps the child's body on the side of the chest away from the examination bed 11, and then the water bag cavity 23 cooperates with the depression 12 to fix the child's body, and then the child's body is limited by the gravity of the water. Compared with the traditional method of fixing and restraining with straps, the water bag cavity 23 is driven by the gravity of the water to move, and cooperates with the depression 12 to fit and wrap the child, and the tightening feeling caused by the straps will not be generated. Then, the child will have a better experience when undergoing medical imaging examinations, avoiding the phenomenon of children crying due to the restraint caused by the straps, thereby shortening the time for children to undergo medical imaging examinations.

[0056] In other optional embodiments, warm water can be directly added to the water storage chamber to reduce the heating time, and the temperature of the warm water is 34-35 degrees Celsius).

[0057] Since the rotating plate 22 and the expansion plate 24 are provided with theme patches on the side close to the examination bed 11, and the theme patches are preferably marine-themed, and several models are placed in the water bag cavity 23 and the fixed cavity 25, and the models are preferably marine life models, when warm water is injected into the fixed cavity 25, the warm water will impact the models in the fixed cavity 25, and then the marine life models in the fixed cavity 25 will move under the action of the warm water, and the marine-themed patches are provided in the fixed cavity 25, which can attract children's attention, thereby reducing children's fear of the instrument and better cooperating in completing the medical imaging examination;

[0058] And due to the restraint of the water bladder cavity 23 and the depression 12, the child may make slight movements of the hands, feet or body, and the force generated by the slight movement of the body will be fed back to the water bladder cavity 23, so that the water in the water bladder cavity 23 will generate flow force. Since a pipeline is provided between the water bladder cavity 23 and the fixed cavity 25, water will flow in the water bladder cavity 23 and the fixed cavity 25 through the pipeline, and the flow of water will drive the marine life model in the fixed cavity 25 to move, and then the child will have a feeling of being in the ocean, so that the child forgets the illusion that he is undergoing a medical imaging examination, thereby eliminating the child's fear of medical equipment and the absence of adults, and further enabling the child to cooperate with medical staff to complete the medical imaging examination.

[0059] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
