Description

[0001] The present invention relates to the technical field of medical equipment, and in particular to a vertical medical imaging device. Background Art

[0002] Standing CT refers to changing the patient's examination position from the original lying position to a standing or semi-sitting position, and the CT scanning frame changes from being fixed on the ground to vertical up and down linear motion. The heat dissipation of standing CT is similar to that of traditional CT. An air inlet is opened on one side of the shell to allow external cold air to enter the inside of the device. At the same time, a fan is installed on the opposite side of the air inlet to remove the high-temperature gas generated inside the device. During the heat dissipation process, the rotation of the fan brings noise and energy consumption.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] To solve relevant technical problems, such as Figure 1 As shown, an embodiment of the present invention provides a vertical medical imaging device, including:

[0040] The column assembly 1 is arranged in two groups and is relatively distributed. A closed cavity 2 is arranged in the column assembly 1. The column assembly 1 is provided with a first air inlet 6 and a first air outlet 12 which are connected to the cavity 2;

[0041] A CT scanning frame 15, which is disposed between the two sets of column assemblies 1 and can be driven to rise and fall, with both ends of the CT scanning frame 15 being slidably connected to the column assemblies 1, and a second air inlet 13 being disposed on the CT scanning frame 15;

[0042] A heat dissipation channel connected to the CT scanning frame 15;

[0043] A counterweight assembly 3, the counterweight assembly 3 is slidably disposed in the cavity 2;

[0044] A flexible traction member 5, wherein a first end of the flexible traction member 5 is fixedly connected to the counterweight assembly 3, and a second end of the flexible traction member 5 extends out of the column assembly 1 and is fixedly connected to the CT scanning frame 15;

[0045] The first air outlet 12 is connected to the second air inlet 13 through a pipeline. A first one-way valve 7 is provided in the first air inlet 6, and the first one-way valve 7 is configured to allow external air to flow in through the first air inlet 6 in one direction. A second one-way valve 11 is provided in the first air outlet 12, and the second one-way valve 11 is configured to allow gas in the cavity 2 to flow out through the first air outlet 12 in one direction.

[0046] In this embodiment, the column assembly 1 is at least arranged in two groups and distributed relatively, and the column assembly 1 includes a rigid skeleton structure and a shell structure wrapped around the outside of the skeleton structure. A closed cavity 2 needs to be formed inside the column assembly 1. In this embodiment, the cavity 2 is in a long strip shape and extends in the vertical direction. The counterweight assembly 3 is arranged in the cavity 2 and can slide vertically up and down in the cavity 2. The counterweight assembly 3 is connected to the CT scanning frame 15 through a flexible traction member 5. When the CT scanning frame 15 is driven to move up and down, the counterweight assembly 3 moves with it. The flexible traction member 5 can be a belt or a traction rope, etc., which is not limited in this embodiment. Specifically, when the CT scanning frame 15 is driven to rise, the counterweight assembly 3 descends in the cavity 2. When the CT scanning frame 15 is driven to descend, the counterweight assembly 3 rises in the cavity 2. When an air outlet is provided on the cavity 2, the movement of the counterweight assembly 3 in the cavity 2 will drive the air flow in the cavity 2.

[0047] Therefore, in order to utilize the air flow driven by the counterweight assembly 3 to dissipate heat for the CT scanning frame 15, in this embodiment, a first air inlet 6 and a first air outlet 12 are provided on the cavity 2, a first one-way valve 7 is provided in the first air inlet 6, and a second one-way valve 11 is provided in the first air outlet 12. The first one-way valve 7 only allows the gas outside the cavity 2 to flow into the cavity 2 due to the change in air pressure, and the second one-way valve 11 only allows the gas inside the cavity 2 to flow out of the cavity 2 due to the change in pressure.

[0048] In one embodiment, the first air inlet 6 and the first air outlet 12 can be arranged at the upper end of the cavity 2. When the counterweight assembly 3 moves downward in the cavity 2, negative pressure is generated in the cavity 2, and external air enters the cavity 2 through the first air inlet 6. When the counterweight assembly 3 moves upward in the cavity 2, positive pressure is generated in the cavity 2, and the gas in the cavity 2 flows out of the cavity 2 through the first air outlet 12.

[0049] In another embodiment, if Figure 1As shown, both the first air inlet 6 and the first air outlet 12 can be set to two and distributed up and down. When the counterweight assembly 3 moves downward in the cavity 2, the portion of the cavity 2 located at the upper part of the counterweight assembly 3 generates negative pressure, and the lower portion generates positive pressure. Similarly, when the counterweight assembly 3 moves upward in the cavity 2, the portion of the cavity 2 located at the upper part of the counterweight assembly 3 generates positive pressure, and the lower portion generates negative pressure. It can be seen that in the entire process of the up and down movement of the counterweight assembly 3, the cavity 2 includes portions that generate positive pressure and negative pressure, wherein the portion that generates positive pressure can discharge gas through the first air outlet 12, and the portion that generates negative pressure can inhale gas through the first air inlet 6, so that gas is kept input into the CT scanning frame 15 during the lifting and lowering process of the CT scanning frame 15.

[0050] In order to realize the connection between the first air outlet 12 and the CT scanning frame 15, a second air inlet 13 is provided on the CT scanning frame 15 in this embodiment, and the second air inlet 13 and the first air outlet 12 can be connected by a hose or a retractable tube. When the CT scanning frame 15 is raised or lowered, the counterweight assembly 3 moves up and down in the cavity 2. During this process, the external cold air is continuously sucked into the cavity 2 through the first air inlet 6, and the cold air is discharged through the first air outlet 12. After flowing through the pipeline, the cold air enters the CT scanning frame 15 through the second air inlet 13, and is discharged through the heat dissipation channel after heat exchange with the heat source in the CT scanning frame 15. In one embodiment of the heat dissipation channel, the heat dissipation channel can be a heat dissipation outlet opened on the CT scanning frame 15 or a heat dissipation pipeline connected to the CT scanning frame 15, etc.

[0051] On one hand, the present invention achieves the purpose that the counterweight assembly 3 is lifted and lowered in the closed cavity 2 during the lifting and lowering of the CT scanning frame 15, and positive and negative pressures are generated in the cavity 2 during the lifting and lowering of the counterweight assembly 3. When negative pressure is generated, the external cold air is sucked into the cavity 2 through the first air inlet 6, and when positive pressure is generated, the cold air in the cavity 2 is discharged from the first air outlet 12 and enters the CT scanning frame 15 through the second air inlet 13, and is discharged from the heat dissipation channel after heat exchange, thereby achieving the purpose of cooling the scanning frame without the need for additional electric heat dissipation equipment, relying on the movement of the counterweight assembly 3 itself to cool the scanning frame, reducing the noise and power consumption generated in the heat dissipation process, and thus solving the problem of large noise and energy consumption caused by heat dissipation of the standing position CT equipment in the related art;

[0052] On the other hand, since the inlet for external air is located on the column assembly 1 and the outlet is located on the CT scanning frame 15, the distance between the inlet and the outlet is relatively far, which is conducive to the circulation and exchange of air and improves the heat dissipation effect. In addition, since the inlet and the outlet are far apart, the patient located in the middle of the CT scanning frame 15 is not easily affected by the air flow.

[0053] To improve heat dissipation efficiency, Figure 1 As shown, in this embodiment, the first air inlet 6 and the first air outlet 12 are both provided with two and distributed up and down. Specifically, in this embodiment, the cavity 2 includes an upper cavity 200 and a lower cavity 201, the upper cavity 200 and the lower cavity 201 are respectively located at the upper end and the lower end of the counterweight assembly 3, the first air outlet 12 is provided with at least two and communicated with the upper cavity 200 and the lower cavity 201 respectively; the first air inlet 6 is provided with at least two and communicated with the upper cavity 200 and the lower cavity 201 respectively.

[0054] Specifically, it should be noted that, in this embodiment, the counterweight assembly 3 divides the cavity 2 into two parts, an upper part and an lower part. As the counterweight assembly 3 moves up and down, the volumes of the upper cavity 200 and the lower cavity 201 change. Two first air outlets 12 are provided and are respectively connected to the upper cavity 200 and the lower cavity 201. Two first air inlets 6 are provided and are respectively connected to the upper cavity 200 and the lower cavity 201. During the upward movement of the counterweight assembly 3, the upper cavity 200 is compressed so that the cold air in the upper cavity 200 flows out through the first air outlet 12 and enters the CT scanning frame 15. At the same time, negative pressure is generated in the lower cavity 201, and the external cold air enters the lower cavity 201 through the first air inlet 6 of the lower cavity 201. During the downward movement of the counterweight assembly 3, the above process is reversed, so that the cold air can be continuously passed into the CT scanning frame 15, thereby improving the heat dissipation effect of the CT scanning frame 15.

[0055] Since the column assembly 1 is arranged on both sides of the CT scanning frame 15, and two first air outlets 12 are arranged on the column assembly 1 on the same side, in this embodiment, in order to match the first air outlet 12, the second air inlet 13 is arranged to be at least four and distributed at the four corners of the CT scanning frame 15, and the second air inlet 13 is connected to the corresponding first air outlet 12 through a pipeline. On this basis, the heat dissipation channel includes a second air outlet 14 opened on the CT scanning frame 15, the second air outlet 14 is arranged to be at least two and located on the center line of the CT scanning frame 15, and the second air outlet 14 is located on both sides of the CT scanning frame 15. In order to reduce the impact of air flow on patients, in this embodiment, the second air inlet 13 and the second air outlet 14 are both arranged on the outside of the CT scanning frame 15.

[0056] On the basis of the above-mentioned embodiment, when the first air inlet 6 is arranged on the side elevation of the column assembly 1, the suction force generated by the first air inlet 6 during the movement of the counterweight assembly 3 may affect the surrounding environment or personnel. Therefore, in this embodiment, a total air inlet is arranged at the upper end of the column assembly 1, and the total air inlet is connected to the first air inlet 6 through a pipeline. During the movement of the counterweight assembly 3, the total air inlet located at the upper end of the column assembly 1 generates suction force, thereby reducing the impact on the surroundings.

[0057] In another embodiment, in order to reduce the impact of air intake and air outlet on the patient, the air intake and air outlet mode is adjusted in this embodiment. Figure 2 As shown, in this embodiment, for the air duct on the left side of the vertical medical imaging device, it includes a total air inlet duct 16, the total air inlet of the total air inlet duct 16 is located at the lower end, and the total air inlet duct 16 is connected in parallel with the first air inlet 6 of the upper chamber 200 and the first air inlet 6 of the lower chamber 201. The first air outlet 12 of the upper chamber 200 can be connected to one of the second air inlets 13 on the CT scanning frame 15 through a separate air inlet duct 23, and the first air outlet 12 of the lower chamber 201 can be connected to one of the second air inlets 13 on the CT scanning frame 15 through a separate air inlet duct 23. Of course, the first air outlet 12 of the upper chamber 200 and the first air outlet 12 of the lower chamber 201 can also be connected in parallel to one or two second air inlets 13 on the CT scanning frame 15 through the same air inlet duct, and the air duct on the right side of the vertical medical imaging device is arranged in the same way.

[0058] For heat dissipation and air outlet, in this embodiment, the heat dissipation channel includes two heat dissipation branches 17 corresponding to the air inlet pipes 23 on both sides, and the upper and lower ends of the heat dissipation branches 17 are provided with heat dissipation ports 18. The heat dissipation branches 17 are provided with a first interface 19 and a second interface 21 distributed up and down. The portion of the air inlet pipe 23 connected to the upper first air outlet 12 is connected to the first interface 19, and the portion of the air inlet pipe 23 connected to the lower first air outlet 12 is connected to the second interface 21;

[0059] The heat dissipation branch pipe 17 is provided with a first electrically controlled valve 20 and a second electrically controlled valve 22 . The first electrically controlled valve 20 is provided between the first interface 19 and the heat dissipation port 18 at the upper end, and the second electrically controlled valve 22 is provided between the second interface 21 and the heat dissipation port 18 at the lower end.

[0060] Specifically, for the heat dissipation air duct on the left side of the vertical medical imaging device, the heat dissipation branch pipe 17 on the left side is connected in parallel to the upper air inlet pipe 23 and the lower air inlet pipe 23, and electric control valves are respectively arranged at the upper and lower parts of the heat dissipation branch pipe 17 on the left side. During operation, when the CT scanning frame 15 moves upward, the second electric control valve 22 is closed, the first electric control valve 20 is opened, the counterweight assembly 3 compresses the lower chamber 201, and the cold air in the lower chamber 201 enters the CT scanning frame 15 through the lower air inlet pipe 23. The closed second electric control valve 22 can prevent the cold air from being discharged directly from the heat dissipation port 18 at the lower end of the heat dissipation branch pipe 17 without passing through the CT scanning frame 15. After entering the CT scanning frame 15, the cold air undergoes heat exchange, and the hot air after heat exchange enters the upper air inlet pipe 23 and the upper heat dissipation branch pipe 17 through the second air inlet 13 on the CT scanning frame 15 connected to the upper air inlet pipe 23, and then is discharged through the heat dissipation port 18 at the upper part of the heat dissipation branch pipe 17.

[0061] Similarly, when the CT scanning frame 15 moves downward, the first electrically controlled valve 20 is closed, and the second electrically controlled valve 22 is opened, and the hot air after heat exchange enters the lower air inlet duct 23 and the lower heat dissipation branch pipe 17 from the second air inlet port 13 connected to the lower air inlet duct 23 on the CT scanning frame 15, and then is discharged through the heat dissipation port 18 at the lower part of the heat dissipation branch pipe 17, so that the hot air is only discharged from the upper and lower ends of the equipment, reducing the impact on patients in the CT scanning frame 15.

[0062] The same is true for the heat dissipation duct and heat dissipation process on the right side of the vertical medical imaging device, which will not be described in detail in this embodiment. In addition, during the heat dissipation process, the hot air flowing upward or downward will also contact the second one-way valve 11, and the second one-way valve 11 can also prevent the hot air from flowing back into the upper cavity 200 and the lower cavity 201. In some scanning environments, the CT scanning frame 15 performs CT scanning in a suspended state, and the counterweight assembly 3 is suspended in the cavity 2 during this process. Therefore, in order to better dissipate the heat of the CT scanning frame 15, an exhaust fan is provided in the first air outlet 12 in this embodiment. When the CT scanning frame 15 is suspended, the exhaust fan can dissipate heat to the CT scanning frame 15.

[0063] During the lifting and lowering process of the CT scanning frame 15, the flexible traction member 5 will move because it is connected between the CT scanning frame 15 and the counterweight assembly 3. In order to reduce the friction of the movement of the flexible traction member 5, a pulley 10 is provided at the upper end of the cavity 2 in this embodiment, and the flexible traction member 5 is fixedly connected to the counterweight assembly and the CT scanning frame 15 after passing the pulley 10.

[0064] Since the flow of cold air in the cavity 2 is achieved by the up and down movement of the counterweight assembly 3, in order to better guide and promote the air flow, in this embodiment, a rubber ring 4 is fixed to the ring side of the counterweight assembly 3, and the outer side of the rubber ring 4 fits with the inner side of the cavity 2. The rubber ring 4 increases the sealing performance between the counterweight assembly 3 and the cavity 2.

[0065] Since one end of the flexible traction member 5 needs to be connected to the counterweight assembly 3 in the cavity 2, and the other end needs to pass through the cavity 2 and connect to the CT scanning frame 15, a mounting hole needs to be opened on the cavity 2 for the flexible traction member 5 to pass through and slide. Specifically, in this embodiment, a mounting hole is opened at the inner upper end of the column assembly 1. In order to reduce the friction between the flexible traction member 5 and the mounting hole, in this embodiment, a connecting sleeve is fixed in the mounting hole, and the connecting sleeve includes a rigid outer shell 8 and a flexible inner core 9. A through sliding hole is set in the flexible inner core 9, and the flexible traction member 5 slides through the sliding hole and fits tightly with the inner wall of the sliding hole.

[0066] Specifically, in this embodiment, the rigid outer shell 8 can ensure the connection strength between the connecting sleeve and the mounting hole, and the flexible inner core 9 wraps the flexible traction member 5, which can make the flexible traction member 5 slide while improving the sealing performance, so that the cold air in the cavity 2 can flow better.

[0067] In order to facilitate the lifting and lowering of the CT scanning frame 15, in this embodiment, a slide rail is provided on the inner side of the column assembly 1, and sliders are provided on both sides of the CT scanning frame 15, and the sliders are engaged with the slide rails and slidably connected. Furthermore, a linear drive mechanism is provided on the column assembly 1, and the output end of the linear drive mechanism is transmission-connected with the slider to drive the slider to move vertically and linearly.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Within the spirit and principle of the present invention, any modification, equivalent replacement, improvement, etc. made shall be included in the protection scope of the present invention.
