Description

Technical Field

[0001] This application relates to the technical field of imaging examinations, and particularly to an imaging examination assistance device for children. Background Art

[0002] Imaging examination generally refers to the medical use of scanning a patient's body to determine the conditions of various systems of the human body. During the imaging examination process, it is also necessary to shield the parts of the human body that do not need to be examined with a protective lead apron to reduce the harm of radiation to the human body.

[0003] In the related art, a CT examinee radiation protection cabin is disclosed, which includes a mobile cabin support and a mobile cabin. The protection cabin is composed of a plurality of mobile cabins of different sizes connected in a nested manner. The periphery of each mobile cabin is enclosed by lead plates. The support of the mobile cabin adopts an approximately rectangular structure, and the four corners and the top are arc-shaped. The bottom of the mobile cabin is slidably arranged, and the smaller mobile cabin can slide into the larger mobile cabin, so that the mobile cabins can overlap each other.

[0004] However, in the above structure, since the mobile cabin has a fixed shape, it is easy to generate a large gap around a smaller child patient, and thus the radiation protection effect is poor. Summary of the Invention

[0005] In order to reduce the gap around a child patient to improve the protection effect, this application provides an imaging examination assistance device for children.

[0006] This application provides an imaging examination assistance device for children, adopting the following technical solution: An imaging examination assistance device for children includes a bottom plate. An upper body lead apron and a lower body lead apron are arranged on the bottom plate. A receiving groove is arranged inside the bottom plate. Two chutes parallel to the length direction of the bottom plate are spaced apart on the upper surface of the bottom plate. The chutes communicate with the receiving groove. The upper body lead apron and the lower body lead apron extend into the receiving groove from the positions of the two chutes. A winding component and a tensioning component are arranged in the receiving groove. One side of the lower body lead apron located in the chute is mounted on the winding component, and the part of the lower body lead apron located outside the bottom plate is tightened by the winding component; one side of the upper body lead apron located in the chute is mounted on the tensioning component, and the part of the upper body lead apron located outside the bottom plate is tightened by the tensioning component; the upper body lead apron and the lower body lead apron move along the chutes to positions where they overlap or separate from each other.

[0007] By adopting the above technical solution, during use, the bottom plate is placed horizontally. The bottom plate is used for a child patient to lie flat. Then, the upper body lead apron and the lower body lead apron move along the sliding groove to the appropriate positions of the patient, and the overlapping of the upper body lead apron and the lower body lead apron can arbitrarily adjust the shielding positions of the upper body lead apron and the lower body lead apron. Then, through the winding component, the part of the lower body lead apron located at the bottom plate is tightened, so that the lower body lead apron adheres to the patient's body. At the same time, the upper body lead apron is tightened through the tensioning component. Thus, the upper body lead apron and the lower body lead apron reduce the gap around the patient's body, thereby improving the protection effect. At the same time, since the tightening of the upper body lead apron and the lower body lead apron can restrain the child patient and reduce movement during the imaging examination, the imaging quality can be improved.

[0008] Preferably, the winding component includes a winding motor, a screw rod, and a connecting sleeve. The screw rod is arranged parallel to the sliding groove. The connecting sleeve is installed on the screw rod and a positioning member is arranged between the connecting sleeve and the screw rod. One side of the lower body lead apron located in the sliding groove is fixed on the side wall of the connecting sleeve. The winding motor is fixed on the bottom plate and is coaxially fixed with the screw rod.

[0009] By adopting the above technical solution, when the connecting sleeve is fixed on the screw rod through the positioning member, the winding motor works to drive the screw rod to rotate. The connecting sleeve on the screw rod rotates simultaneously with the screw rod. Thus, the lower body lead apron can be wound around the connecting sleeve, and then the lower body lead apron located outside the bottom plate can be tightened.

[0010] Preferably, the positioning member is an electromagnet. A positioning groove is formed on the side wall of the screw rod along the length direction of the screw rod. The electromagnet is fixed on the connecting sleeve and is used for inserting into the positioning groove. The connecting sleeve is in threaded connection with the screw rod.

[0011] By adopting the above technical solution, the positioning member adopts an electromagnet. The electromagnet can be inserted into the positioning groove to make the connecting sleeve and the screw rod rotate simultaneously. When the electromagnet extends out of the positioning groove, the screw rod rotates relative to the connecting sleeve. Thus, the connecting sleeve can drive the lower body lead apron to move along the sliding groove, which is convenient for adjusting the position of the lower body lead apron.

[0012] Preferably, the tensioning component includes a fixed strip, a driving motor, a winding wheel, and a pulling rope. One side of the upper body lead apron located in the sliding groove is fixed on the fixed strip. The driving motor is fixed on the bottom plate. A rotating shaft is coaxially fixed on the output shaft of the driving motor. The winding wheel is installed on the rotating shaft. One end of the pulling rope is fixed on the winding wheel, and the other end is fixed on the fixed strip.

[0013] By adopting the above technical solution, the driving motor drives the rotating shaft to rotate. The winding wheel on the rotating shaft rotates simultaneously. Thus, the winding wheel winds the pulling rope, making the fixed strip move closer to the rotating shaft. Thereby, the upper body lead apron can be tensioned through the movement of the fixed strip.

[0014] Preferably, a slide bar is slidably connected inside the bottom plate. The sliding direction of the slide bar relative to the bottom plate is parallel to the sliding groove. The winding wheel is slidably connected to the rotating shaft. The slide bar is connected to a power assembly that drives the sliding relative to the bottom plate. The two end faces of the slide bar are in contact with the winding wheel. The fixing bar is slidably connected to the slide bar, and the sliding direction of the fixing bar relative to the slide bar is perpendicular to the sliding direction of the slide bar relative to the bottom plate.

[0015] By adopting the above technical solution, the slide bar is slidably connected to the bottom plate, and the slide bar moves through the power assembly. When the slide bar moves under the action of the power assembly, the slide bar can drive the winding wheel to move along the length direction of the rotating shaft. At the same time, the fixing bar also slides under the action of the slide bar, so that the fixing bar can drive the upper body lead apron to slide in the sliding groove, facilitating the adjustment of the position of the upper body lead apron.

[0016] Preferably, the power assembly includes a power motor and a gear. The power motor is fixed on the bottom plate. The gear is coaxially fixed on the output shaft of the power motor. A rack is provided on the slide bar, and the rack is parallel to the length direction of the slide bar. The gear meshes with the rack.

[0017] By adopting the above technical solution, the rack is arranged parallel to the slide bar. When the power motor drives the gear to rotate, the gear meshes with the rack, so that the gear can drive the rack, and further make the slide bar slide along the length direction of the bottom plate, driving the fixing bar to move.

[0018] Preferably, the upper body lead apron and the lower body lead apron are separately arranged outside the bottom plate, and a plurality of magic tapes are fixedly arranged on the separated side edges.

[0019] By adopting the above technical solution, the upper body lead apron and the lower body lead apron are separated outside the bottom plate, so that the patient can first lie on the bottom plate, and then the upper body lead apron and the lower body lead apron can wrap the patient through the magic tapes. At the same time, the plurality of magic tapes can adjust the tightness of the upper body lead apron and the lower body lead apron, facilitating the tightening of the lower body lead apron and the upper body lead apron by the winding assembly and the tensioning assembly.

[0020] Preferably, a headrest is provided at one end of the bottom plate. A head lead apron is detachably installed on the headrest, and magic tapes are provided at both ends of the head lead apron.

[0021] By adopting the above technical solution, the head lead apron is detachably connected to the headrest. When imaging examination of the head is not required, the head of the patient is wrapped by the head lead apron to reduce the irradiation of the head.

[0022] Preferably, a plurality of flexible protrusions are arranged on the inner side surface of one end of the head lead apron, and the flexible protrusions are arranged at intervals.

[0023] By adopting the above technical solution, a plurality of flexible protrusions are arranged on the inner side of the head lead apron and can contact the patient's face. Through the gaps between the plurality of flexible protrusions, it is convenient for the patient to breathe, and the flexible protrusions can improve the comfort of the patient.

[0024] Preferably, the distance between the two chutes is 8-11 cm.

[0025] By adopting the above technical solution, the distance between the two chutes enables most patients to press the positions of the two chutes on both sides of the body when lying on the bottom plate, so that the upper body lead apron and the lower body lead apron fit more closely to the patient. At the same time, the interval is not too small to cause the upper body lead apron and the lower body lead apron to press more under the patient's body and be difficult to move.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The part of the lower body lead apron located at the bottom plate is tightened by the winding component, so that the lower body lead apron adheres to the patient's body. At the same time, the upper body lead apron is tightened by the tensioning component, so that the upper body lead apron and the lower body lead apron reduce the gap around the patient's body, thereby improving the protection effect; 2. The upper body lead apron and the lower body lead apron wrap the patient through the magic tape, and at the same time, a plurality of magic tapes can adjust the tightness of the upper body lead apron and the lower body lead apron, thereby facilitating the tightening of the lower body lead apron and the upper body lead apron by the winding component and the tensioning component; 3. By pressing the positions of the two chutes on both sides of the body, the upper body lead apron and the lower body lead apron fit more closely to the patient. Description of the Drawings

Detailed implementation manners

[0029] The following further elaborates on this application in conjunction with the attached Figure 1-7 drawings.

[0030] The embodiment of this application discloses an auxiliary device for children's imaging examination. Refer to Figure 1 and Figure 2 , including an examination bed 1, which is configured to cooperate with a CT scanner and is used for a patient to lie flat for examination. A bottom plate 2 is placed on the upper surface of the examination bed 1. A headrest 3 is provided at one end of the bottom plate 2. At the same time, an upper body lead apron 4 and a lower body lead apron 5 are provided on the bottom plate 2. When performing an imaging examination on a child, first place the bottom plate 2 on the upper surface of the examination bed 1, then let the child lie on the upper surface of the bottom plate 2, and then use the upper body lead apron 4 and the lower body lead apron 5 to shield the body parts that do not need radiation.

[0031] Refer to Figure 2 and Figure 3, two sliding grooves 21 are formed on the upper surface of the bottom plate 2 along the length direction of the bottom plate 2, and a receiving groove 22 is arranged inside the bottom plate 2. The sliding grooves 21 communicate with the receiving groove 22. The two sliding grooves 21 are arranged in parallel and at intervals, and the distance between the two sliding grooves 21 is set to 8-11 cm, so that the two sliding grooves 21 can be located under the patient's body. The upper body lead apron 4 and the lower body lead apron 5 are both inserted into the receiving groove 22 from the position of the sliding grooves 21. A winding component 6 and a tensioning component 7 are arranged in the receiving groove 22. The winding component 6 is located between the two sliding grooves 21, and the tensioning component 7 is located at a position on the lower side of the winding component 6. The side of the lower body lead apron 5 located in the sliding groove 21 is fixed on the winding component 6, and the side of the upper body lead apron 4 located in the sliding groove 21 is fixed on the tensioning component 7. Moreover, the part of the upper body lead apron 4 located in the receiving groove 22 is under the winding component 6. The upper body lead apron 4 is slidably arranged on the bottom plate 2 along the length direction of the two sliding grooves 21, and the lower body lead apron 5 is slidably arranged on the bottom plate 2 along the length direction of the two sliding grooves 21. During use, the positions of the upper body lead apron 4 and the lower body lead apron 5 in the length direction of the bottom plate 2 can be adjusted. When imaging examination is needed at the middle position of the child's body, the upper body lead apron 4 and the lower body lead apron 5 are separated from each other. When imaging examination is needed at the upper or lower part of the child's body, the lower body lead apron 5 is folded into the upper body lead apron 4, and a part of the winding component 6 slides into the upper body lead apron 4.

[0032] Reference Figure 2 and Figure 3 , the upper body lead apron 4 and the lower body lead apron 5 are separately arranged on one side outside the bottom plate 2, and magic tapes 8 are fixedly arranged on the separated side edges. The magic tapes 8 can be arranged in multiple numbers along the width direction of the upper body lead apron 4 and the lower body lead apron 5. In this embodiment, three are arranged. During use, first open the position of the magic tape 8 to spread the upper body lead apron 4 and the lower body lead apron 5 apart. Then, after the child patient lies on the bottom plate 2, wrap the upper body lead apron 4 and the lower body lead apron 5 around the patient's body and adjust the tightness of the upper body lead apron 4 and the lower body lead apron 5 through the magic tape 8. Then, tighten the lower body lead apron 5 through the winding component 6 to make the lower body lead apron 5 above the bottom plate 2 contact the bodies of child patients with different weights; at the same time, tighten the upper body lead apron 4 through the tensioning component 7 again to make the upper body lead apron 4 above the bottom plate 2 contact the bodies of child patients with different weights, so that the upper body lead apron 4 and the lower body lead apron 5 can be attached to the child patient, reducing the gaps around the patient's body and improving the protection effect; in addition, for child patients, the tightened upper body lead apron 4 and lower body lead apron 5 can reduce the movement of the child during the imaging examination process and improve the quality of the image.

[0033] Reference Figure 2, a head lead apron 31 is provided at the position of the headrest 3. The head lead apron 31 is used to protect the patient's head. The head lead apron 31 is detachably connected to the headrest 3 or placed on the upper surface of the headrest 3. When the patient does not need to have a head imaging examination, the head lead apron 31 is used to protect the head; when a head imaging examination is needed, the head lead apron 31 is removed from the position of the headrest 3. A plurality of flexible protrusions 311 are provided on the inner side surface of one end of the head lead apron 31. The flexible protrusions 311 are opposite to the patient's face position. The plurality of flexible protrusions 311 are arranged at intervals. After the patient is protected by the head lead apron 31, the patient can breathe through the gaps between the flexible protrusions 311. At the same time, magic tapes 8 are provided at both ends of the head lead apron 31 to wrap and fix the head lead apron 31. A transparent lead glass 10 is provided on the head lead apron 31. When the head lead apron 31 wraps the head, the lead glass 10 corresponds to the position of the eyes, reducing the sense of fear caused by the head lead apron 31 wrapping the head.

[0034] Reference Figure 4 and Figure 5 , the winding assembly 6 includes a winding motor 61, a screw rod 62 and a connecting sleeve 63 mounted on the screw rod 62. A positioning member 64 is provided between the connecting sleeve 63 and the screw rod 62. The winding motor 61 is fixed on the bottom plate 2. The screw rod 62 is arranged along the length direction of the bottom plate 2. The screw rod 62 is located at the upper middle position of the receiving groove 22. The connecting sleeve 63 is sleeved on the screw rod 62, and the connecting sleeve 63 is threadedly connected to the screw rod 62. The output shaft of the winding motor 61 is coaxially and fixedly connected to the screw rod 62. When the positioning member 64 fixes the screw rod 62 and the connecting sleeve 63, the winding motor 61 can drive the connecting sleeve 63 to rotate through the screw rod 62; when the positioning member 64 releases the fixing of the connecting sleeve 63 and the screw rod 62, the connecting sleeve 63 moves along the length direction of the screw rod 62 under the action of the screw rod 62. One end of the lower body lead apron 5 located in the sliding groove 21 is fixed on the side wall of the connecting sleeve 63, so that when the connecting sleeve 63 rotates, the lower body lead apron 5 can be wound onto the side wall of the connecting sleeve 63. When the winding motor 61 drives the connecting sleeve 63, when the lower body lead apron 5 wraps the body, the wrapping condition of the lower body lead apron 5 can be judged according to the driving force of the winding motor 61, so as to stop the winding motor 61 in time. When the staff pulls the lower body lead apron 5 outside the sliding groove 21, the rotation of the connecting sleeve 63 can be blocked, and then the rotation of the screw rod 62 can adjust the position of the lower body lead apron 5, so that the lower body lead apron 5 can be adjusted according to the position where imaging examination is needed. The winding motor 61 can also automatically tighten the lower body lead apron 5 after the scanning instruction starts or automatically loosen the lower body lead apron 5 after the scanning instruction ends.

[0035] Reference Figure 5, the positioning member 64 is an electromagnet. A positioning groove 621 is provided along the length direction of the screw rod 62. The positioning groove 621 is located on the side wall of the screw rod 62. The electromagnet is fixed on the side wall of the connecting sleeve 63, and the movable end of the electromagnet penetrates through the side wall of the connecting sleeve 63 for insertion into the positioning groove 621. When the movable end of the electromagnet is inserted into the positioning groove 621, the rotation of the screw rod 62 can drive the connecting sleeve 63 to rotate simultaneously. When the movable end of the electromagnet is pulled out from the positioning groove 621, the connecting sleeve 63 is loosened from the screw rod 62, so that the rotation of the screw rod 62 can drive the connecting sleeve 63 to move along the length direction of the screw rod 62.

[0036] Reference Figure 4 and Figure 6 , the tensioning assembly 7 includes a fixed strip 71, a driving motor 72, a winding wheel 73 and a pulling rope 74. The fixed strip 71 is arranged along the length direction of the bottom plate 2. The side of the upper body lead apron 4 located in the sliding groove 21 is fixed on the fixed strip 71, and two support rollers 75 are arranged in the accommodating groove 22. The two support rollers 75 are rotatably connected to the bottom plate 2, so that the support rollers 75 are used to abut against the upper body lead apron 4 to reduce the friction between the upper body lead apron 4 and the bottom plate 2. The driving motor 72 is fixed on the bottom plate 2. A rotating shaft 76 is coaxially and fixedly arranged on the output shaft of the driving motor 72. The rotating shaft 76 is rotatably installed on the bottom plate 2. The winding wheel 73 is installed on the rotating shaft 76, so that the rotating shaft 76 can drive the winding wheel 73 to rotate. One end of the pulling rope 74 is fixed on the side wall of the winding wheel 73, and the other end is fixed on the fixed strip 71. A plurality of pulling ropes 74 can be arranged along the length direction of the fixed strip 71, and each pulling rope 74 corresponds to a winding wheel 73. When the driving motor 72 rotates a plurality of winding wheels 73, the fixed strip 71 moves closer to the winding wheel 73, thereby pulling the upper body lead apron 4 into the accommodating groove 22 to make the part of the upper body lead apron 4 above the bottom plate 2 close to the patient; when the upper body lead apron 4 contacts the patient's body, the force on the driving motor 72 increases, so that the wrapping condition of the upper body lead apron 4 can be judged according to the driving force of the driving motor 72 to stop the driving motor 72 in time; the driving motor 72 can also automatically tighten the upper body lead apron 4 after the scanning instruction starts or automatically loosen the upper body lead apron 4 after the scanning instruction ends.

[0037] Reference Figure 6 and Figure 7, a slide bar 77 is arranged in the accommodation groove 22. The slide bar 77 is slidably connected to the bottom plate 2 along the length direction of the bottom plate 2. The slide bar 77 is connected with a power assembly 9 for driving the slide bar 77 to slide along the length direction of the bottom plate 2. A protrusion 731 is arranged on the inner side of the winding wheel 73. A guiding groove 761 is formed on the side wall of the rotating shaft 76. The protrusion 731 is slidably fitted in the guiding groove 761. The guiding groove 761 is arranged along the length direction of the rotating shaft 76. And the winding wheel 73 is located inside the slide bar 77, so that both end faces of the winding wheel 73 are restricted by the slide bar 77. Thus, when the slide bar 77 moves along the length direction of the bottom plate 2, the winding wheel 73 slides along the length direction of the rotating shaft 76 under the action of the slide bar 77. A guide rod 78 is arranged on the fixing bar 71. The length direction of the guide rod 78 is parallel to the length direction of the pulling rope 74. One end of the guide rod 78 is fixed on the fixing bar 71, and the other end is slidably connected to the slide bar 77. The sliding direction of the guide rod 78 relative to the slide bar 77 is perpendicular to the sliding direction of the slide bar 77 relative to the bottom plate 2. When the slide bar 77 slides relative to the bottom plate 2, the fixing bar 71 also moves along with the slide bar 77.

[0038] Reference Figure 7 , the power assembly 9 includes a power motor 91 and a gear 92. The power motor 91 is fixed on the bottom plate 2. The gear 92 is coaxially fixed on the output shaft of the power motor 91. A rack 93 is arranged along the length direction of the slide bar 77. The rack 93 meshes with the gear 92, so that the gear 92 can drive the rack 93 to move. Thus, the slide bar 77 can move along the length direction of the bottom plate 2 under the action of the power motor 91. Further, the position of the upper body lead apron 4 connected to the fixing bar 71 along the length direction of the bottom plate 2 can be adjusted, so that the upper body lead apron 4 can be adjusted according to the needs of the imaging examination position.

[0039] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
