Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically referring to a mobile CT image viewing stand. Background Technology

[0002] Currently, X-ray examination is a routine method for diagnosing diseases. Doctors need to use the information provided by CT scans to assist in diagnosis. Existing CT scan reading light boxes are fixed on the wall next to the doctor's desk. Patients are separated from the CT scan reading light box by the desk, which is not conducive to communication between doctors and patients. Furthermore, doctors cannot observe the fine details of the film by relying solely on the naked eye, which can easily lead to misjudgment and cause inconvenience to the doctor's diagnosis. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a mobile CT image viewing stand, which effectively solves the above problems.

[0004] The technical solution adopted by this utility model is as follows: This utility model proposes a mobile CT image viewing stand, including a support assembly, a rotating and lifting assembly, and a light box assembly. The light box assembly is disposed on the rotating and lifting assembly, which is disposed on the support assembly. The support assembly includes a four-legged support frame, a four-legged support base, a one-way valve, a foot pedal, and a damping device. The four-legged support frame is disposed on the four-legged support base and has a damping device groove, a sliding air chamber, and a one-way valve fixing hole. The four-legged support base has a foot pedal. The plate has a rotating boss, the one-way valve is located in the one-way valve fixing hole, and the damping device is located in the damping device groove; the one-way valve is provided with a valve sleeve, a valve cover, a valve cover return spring, and a venting base, the venting base is located at the lower end of the valve sleeve, the valve cover return spring is located on the venting base, the valve cover is located on the valve cover return spring, the foot pedal is provided with a venting rod, a venting rod return spring, and a rotating shaft, the rotating shaft rotates on the foot pedal rotating boss, the venting rod return spring is located on the venting base, and the venting rod is located inside the one-way valve.

[0005] Preferably, by manually lifting the rotating lifting assembly, external gas enters the sliding air chamber through the one-way valve. When the hand is released, the internal air pressure of the sliding air chamber keeps the rotating lifting assembly at its current height. By manually stepping on the foot pedal, the venting rod lifts the valve sleeve, and the gas in the sliding air chamber is discharged through the one-way valve, causing the rotating lifting assembly to descend and thus reducing the height of the device. This achieves the technical effect of manually controlling the height of the film reader.

[0006] Furthermore, the damping device is provided with a positioning plate and a ball. The positioning plate is provided with a ball hole, a damping pad and a fixed support. The ball is disposed in the ball hole, the damping pad is disposed on the upper end face of the ball hole, the damping device groove is provided with a damping pad slot and a ball hole, the fixed support is disposed in the damping pad slot, and the ball is disposed in the ball hole.

[0007] Furthermore, the rotating lifting assembly includes a lifting rod, a light box rotating rod, and a light box vertical rod. The lifting rod is located inside the sliding air chamber, the light box rotating rod is located on the lifting rod, and the light box vertical rod is located on the lifting rod.

[0008] Furthermore, the lifting rod is provided with a rolling groove, a vertical rod sliding groove and a rotating rod connecting post.

The light box rotating rod is provided with a locking boss, a lifting rod connecting hole and a light box connecting hole. The rotating rod connecting post rotates in the lifting rod connecting hole.

[0009] Preferably, by setting a damping device on the lifting rod and the four-legged support frame, when the lifting rod moves upward, the balls roll in the ball holes under the friction of the friction pads but do not contact the damping pads, thus reducing the resistance when manually lifting the lifting rod; when the lifting rod descends, the balls press tightly against the damping pads under the friction, increasing the friction of the rolling balls, causing the balls to roll or slide in the rolling grooves, increasing the friction of the lifting rod descending, and preventing the lifting rod from descending too quickly, thereby damaging the device.

[0010] Furthermore, the vertical rod of the light box is provided with a rotating rod locking hole, a light box rotating hole, a battery slot, a wire hole, a lithium battery, a wire, and a light box switch. The lithium battery is located in the battery slot, the wire is connected to the lithium battery, the wire is located in the wire hole, and the light box switch is connected to the wire.

[0011] Preferably, by using a removable and rechargeable lithium battery to power the device, the problem of the device being unable to move due to the short power cord being able to only be near the power source is solved, and the occurrence of patients or medical staff tripping over the external power cord is effectively avoided.

[0012] Furthermore, the lightbox assembly includes an enlargement component, a central boss, an edge boss, a lightbox body, and a loop-shaped light strip. The enlargement component is located inside the lightbox body, the central boss is located at the center of the back of the lightbox body, the edge boss is located on the lower side of the lightbox body, and the loop-shaped light strip is located inside the lightbox body.

The magnifying glass slides on the insulating single rod and the horizontal single rod.

[0014] Preferably, the magnifying glass and the intensifier light are controlled to move synchronously by sliding the vertical bar and the horizontal bar. The doctor can move the magnifying glass to magnify and observe the details of the CT scan. At the same time, the intensifier light, which moves with the magnifying glass, can enhance the brightness of the magnified area, allowing the doctor to discover the patient's problems in detail and accurately.

[0015] Furthermore, the central boss is provided with a central boss post, and the edge boss is provided with an edge boss post. The central boss post rotates in the light box connection hole, and the edge boss post rotates in the light box rotation hole.

[0016] Preferably, doctors can rotate the lightbox assembly to place it vertically or horizontally. When placed horizontally, doctors can point out the location of lesions on the CT scan to the patient face-to-face, which is more conducive to communication between doctors and patients. When placed vertically, the CT scan has a wider display area, which is convenient for multiple doctors to consult together.

[0017] Furthermore, the light box body is provided with wire hole groove, conductive boss, edge slot and white diffuser film, the conductive double rod is provided on the conductive boss, the wire is connected to the loop light strip, and the wire is connected to the conductive boss.

[0018] The beneficial effects of this utility model by adopting the above structure are as follows:

[0019] 1. By manually lifting the rotating lifting assembly, external gas enters the sliding air chamber through the one-way valve. When the hand is released, the internal air pressure of the sliding air chamber keeps the rotating lifting assembly at its current height. By manually stepping on the foot pedal, the venting rod lifts the valve sleeve, and the gas in the sliding air chamber is discharged through the one-way valve, causing the rotating lifting assembly to descend and thus lowering the height of the device. This achieves the technical effect of manually controlling the height of the film reader.

[0020] 2. By installing a damping device on the lifting rod and the four-legged support frame, when the lifting rod moves upward, the balls roll in the ball holes under the friction of the friction pads but do not contact the damping pads, thus reducing the resistance when manually lifting the lifting rod. When the lifting rod descends, the balls press tightly against the damping pads under the friction, increasing the friction of the rolling balls. This causes the balls to roll or slide in the rolling grooves, increasing the friction of the lifting rod's descent and preventing the lifting rod from descending too quickly, which could damage the device.

[0021] 3. By using a removable and rechargeable lithium battery to power the device, the problem of the device being unable to move due to the short power cord being able to only be near the power source is solved, and the occurrence of patients or medical staff tripping over the external power cord is effectively prevented.

[0022] 4. By sliding the vertical and horizontal bars, the magnifying glass and the intensifier light can be moved synchronously. Doctors can move the magnifying glass to magnify and observe the details of the CT scan. At the same time, the intensifier light, which moves with the magnifying glass, can enhance the brightness of the magnified area, allowing doctors to carefully and accurately discover the patient's problems.

[0023] 5. Doctors can rotate the light box assembly to place it vertically or horizontally. When placed horizontally, doctors can point out the location of lesions on the CT scan to the patient face-to-face, which is more conducive to communication between doctors and patients. When placed vertically, the CT scan has a wider display area, which is convenient for multiple doctors to consult together. Attached Figure Description

[0035] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof. Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0037] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] like Figures 1-10 As shown, this utility model proposes a mobile CT image viewing stand, including a support assembly 1, a rotating and lifting assembly 2, and a light box assembly 3. The light box assembly 3 is mounted on the rotating and lifting assembly 2, which is mounted on the support assembly 1. The support assembly 1 includes a four-legged support frame 11, a four-legged support base 12, a one-way valve 13, a foot pedal 14, and a damping device 15. The four-legged support frame 11 is mounted on the four-legged support base 12 and has a damping device groove 111, a sliding air chamber 112, and a one-way valve fixing hole 113. The four-legged support base 12 has a foot pedal rotating boss 121, and the one-way valve 13 is mounted on the one-way valve fixing hole 15. Inside the hole 113, the damping device 15 is located in the damping device groove 111; the one-way valve 13 is provided with a valve sleeve 131, a valve cover 132, a valve cover return spring 133 and a vent base 134. The vent base 134 is located at the lower end of the valve sleeve 131, the valve cover return spring 133 is located on the vent base 134, the valve cover 132 is located on the valve cover return spring 133, the foot pedal 14 is provided with a vent rod 141, a vent rod return spring 142 and a rotating shaft 143. The rotating shaft 143 rotates on the foot pedal rotating boss 121, the vent rod return spring 142 is located on the vent base 134, and the vent rod 141 is located inside the one-way valve 13.

[0039] In this system, by manually lifting the rotating lifting assembly 2, external gas enters the sliding air chamber 112 through the one-way valve 13. When the hand is released, the internal air pressure of the sliding air chamber 112 keeps the rotating lifting assembly 2 at its current height. By manually stepping on the foot pedal 14, the vent rod 141 pushes up the valve sleeve 131, thereby releasing the gas in the sliding air chamber 112 through the one-way valve. The rotating lifting assembly 2 then descends, reducing the height of the device and achieving the technical effect of manually controlling the height of the film reader.

[0040] The damping device 15 is provided with a positioning plate 151 and a ball 152. The positioning plate 151 is provided with a ball hole 1511, a damping pad 1512 and a fixed support 1513. The ball 152 is located in the ball hole 1511 and the damping pad 1512 is located on the upper end face of the ball hole 1511. The damping device groove 111 is provided with a damping pad slot 1111 and a ball hole 1112. The fixed support 1513 is located in the damping pad slot 1111 and the ball 152 is located in the ball hole 1112.

[0041] The rotating lifting assembly 2 is provided with a lifting rod 21, a light box rotating rod 22 and a light box vertical rod 23. The lifting rod 21 is located in the sliding air chamber 112, the light box rotating rod 22 is located on the lifting rod 21, and the light box vertical rod 23 is located on the lifting rod 21.

[0042] The lifting rod 21 is provided with a rolling groove 211, a vertical rod sliding groove 212 and a rotating rod connecting post 213. The rolling groove 211 is provided with a friction pad 2111 and a ball bearing 152 rolls in the rolling groove 211. The light box vertical rod 23 is provided in the vertical rod sliding groove 212. The light box rotating rod 22 is provided with a locking boss 221, a lifting rod connecting hole 222 and a light box connecting hole 223. The rotating rod connecting post 213 rotates in the lifting rod connecting hole 222.

[0043] By installing a damping device 15 on the lifting rod 21 and the four-legged support frame 11, when the lifting rod 21 moves upward, the balls roll in the ball hole 1511 under the friction of the friction pad 2111 but do not contact the damping pad 1512, thus reducing the resistance when manually lifting the lifting rod 21. When the lifting rod 21 moves downward, the balls 152 are pressed against the damping pad 1512 under the friction, and the friction of the rolling balls 152 increases, causing the balls 152 to roll or slide in the rolling groove 211, increasing the friction of the lifting rod 21 as it descends, preventing the lifting rod 21 from descending too quickly and thus damaging the device.

[0044] The vertical pole 23 of the light box is provided with a rotating rod locking hole 231, a light box rotating hole 232, a battery slot 233, a wire hole 234, a lithium battery 235, a wire 236, and a light box switch 237. The lithium battery 235 is located in the battery slot 233, the wire 236 is connected to the lithium battery 235, the wire 236 is located in the wire hole 234, and the light box switch 237 is connected to the wire 236.

[0045] The device is powered by a removable and rechargeable lithium battery 235, which solves the problem that the device can only be moved close to the power source due to the short power cord. It also effectively prevents patients or medical staff from tripping over the external power cord.

[0046] The lightbox assembly 3 includes an enlargement component 31, a central boss 32, an edge boss 33, a lightbox body 34, and a loop light strip 35. The enlargement component 31 is located inside the lightbox body 34, the central boss 32 is located at the center of the back of the lightbox body 34, the edge boss 33 is located on the lower side of the lightbox body 34, and the loop light strip 35 is located inside the lightbox body 34.

[0047] The magnifying component 31 includes a sliding vertical rod 311, a sliding horizontal rod 312, a magnifying glass 313, and an intensifying lamp 314. The sliding vertical rod 311 is provided with a conductive double rod 3111 and an insulating single rod 3112. The sliding horizontal rod 312 is provided on the horizontal double rod 3121 and the horizontal single rod 3122. The conductive double rod 3111 is provided on the horizontal double rod 3121. The intensifying lamp 314 is provided at the intersection of the conductive double rod 3111 and the horizontal double rod 3121. The magnifying glass 313 slides on the insulating single rod 3112 and the horizontal single rod 3122.

[0048] The magnifying glass 313 and the intensifier lamp 314 are controlled to move synchronously by sliding the vertical bar 311 and the horizontal bar 312. The doctor can move the magnifying glass 313 to magnify and observe the details of the CT scan. At the same time, the intensifier lamp 314, which moves with the magnifying glass 313, can enhance the brightness of the magnified area, enabling the doctor to discover the patient's problems in detail and accurately.

[0049] The central boss 32 is provided with a central boss post 321, and the edge boss 33 is provided with an edge boss post 331. The central boss post 321 rotates in the light box connection hole 223, and the edge boss post 331 rotates in the light box rotation hole 232.

[0050] The doctor can rotate the light box assembly 3 to place it vertically or horizontally. When placed horizontally, the doctor can point out the location of the lesion on the CT scan to the patient face-to-face, which is more conducive to communication between the doctor and the patient. When placed vertically, the CT scan has a wider display area, which is convenient for multiple doctors to consult together.

[0051] The light box body 34 is provided with wire hole groove 341, conductive boss 342, edge slot 343 and white diffused light film 344. The conductive double rod 3111 is provided on the conductive boss 342. The wire 236 is connected to the loop light strip 35 and the wire 236 is connected to the conductive boss 342.

[0052] In practical use, the doctor adjusts the height of the device according to their own height (manually lifting the rotating lifting component 2; under the action of air pressure, external gas pushes the valve cover 132 up and enters the sliding air chamber 112; as the lifting rod 21 moves upward, under the action of friction of the friction pad 2111, the ball rolls in the ball hole 1511 but does not contact the damping pad 1512, making the resistance to the lifting rod 21 rising small; when the rotating lifting component 2 is released, under the dual action of the internal air pressure of the sliding air chamber 112 and the elasticity of the valve cover return spring 133, the valve sleeve 131 closes the one-way valve 13, so that the lifting rod 21 maintains the current height and does not fall; by stepping on the foot pedal 14, the rotating shaft 143 rotates in the foot pedal rotating boss 121, and the air release rod returns to its original position). When spring 142 is compressed, vent rod 141 moves upward, causing vent rod 141 to lift valve sleeve 131. This allows gas in sliding air chamber 112 to be discharged from check valve 13. As lifting rod 21 descends, ball bearing 152 adheres tightly to damping pad 1512 under frictional force, increasing the rolling friction of ball bearing 152. This increases the friction of ball bearing 152 rolling or sliding within rolling groove 211, reducing the descent speed of lifting rod 21 and preventing collisions caused by excessive descent. Once the appropriate height is reached, foot pedal 14 is released, and vent rod return spring 142 resets vent rod 141, closing check valve 13. The remaining gas in sliding air chamber 112 keeps rotating lifting assembly 2 at this appropriate height. After adjusting the height, place it aside for later use.

[0053] When a doctor views a patient's CT scan, the device is moved in front of them, the lightbox assembly 3 is rotated to a horizontal position, the CT scan is laid flat on the white astigmatic film 344, and the CT scan is moved and fixed in the edge slot 343. The lightbox switch 237 is turned on, and the loop light strip 35 illuminates the entire white astigmatic film 344. The magnifying glass 313 is moved, which drives the sliding vertical rod 311 and the sliding horizontal rod 312 to move, thereby intensifying the light 314 to follow the movement of the magnifying glass 313, allowing the doctor to better observe the details or lesions on the CT scan. After viewing or when multiple doctors need to consult together, the lightbox body 34 is rotated to a vertical position, and the locking boss 221 is fixed in the rotating rod locking hole 231, thereby fixing the lightbox vertical rod 23 and the lightbox rotating rod 22 to prevent them from rotating. After viewing, the CT scan is removed and returned to the patient, the lightbox switch 237 is turned off, and the CT scan is placed aside for the next use.
