A high-pressure injector

Abstract

The present invention provides a high-pressure injector, comprising a column, a clamping mechanism, and a driving mechanism. The device is moved to one side of an examination bed, with a fixed clamping plate contacting the top surface of the bed board, and a movable clamping plate positioned below the bed board. A motor is then controlled to drive a turntable in forward rotation. The forward rotation of the turntable drives a first connecting sleeve via a transmission assembly to drive the movable clamping plate upward. When the movable clamping plate moves upward and abuts against the bottom surface of the bed board, the movable clamping plate remains stationary. At this point, the movable clamping plate cooperates with the fixed clamping plate to clamp the bed board. The device is easily connected to the examination bed, allowing the device to move with the bed, avoiding pulling on the injection tube. The movement is convenient and safe. After the movable clamping plate cooperates with the fixed clamping plate to clamp the bed board, the forward rotation of the turntable drives multiple groups of support rods to close and rotate upward via the transmission assembly. The upward closing and rotation of the multiple groups of support rods can separate the multiple groups of universal wheels from the ground and retract the multiple groups of support rods, thereby reducing the space occupied by the device and, in turn, reducing the space occupied by the device when it is moved.

Description

Technical Field

[0001] The present invention particularly relates to a high-pressure injector. Background Art

[0002] As an auxiliary device in the radiological diagnosis and treatment system, the high-pressure injector can accurately control the injection speed, dosage and time of the contrast agent, ensuring that the contrast agent is injected into the patient's body at a constant rate in a short period of time. It plays an important role in improving image quality, reducing contrast agent usage, improving examination efficiency, ensuring patient safety and supporting various examination technologies.

[0003] For example, the Chinese patent application number 202220219739.1 discloses a portable high-pressure syringe for radiology departments, including a support seat and a syringe body. A column is fixedly installed in the middle of the top of the support seat, a fixing mechanism is provided on the column, and a locking mechanism is provided on the top of the column. The syringe body is set on the column through the locking mechanism; the fixing mechanism includes a chamber, the chamber is opened in the column, the chamber is close to the support seat, and a slide groove connected to the chamber is opened on one side of the column. A push plate is slidably connected between the slide groove and the chamber, and one end of the push plate passes through the slide groove.

[0004] Most existing high-pressure injectors have simple structures and are not easily connected to the examination bed. When the examination bed needs to be moved to move the patient, the high-pressure injector must also be moved separately, which is cumbersome and can easily pull the syringe, making it unsafe. Furthermore, the high-pressure injector is difficult to store, increasing the space required for movement. Therefore, to address the above technical issues, a high-pressure injector is proposed. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention proposes a high-pressure injector, which is convenient for the device to move with the examination bed after being connected to the bed, avoiding pulling the injection tube, and is convenient and safe to move. It can store the high-pressure injector and reduce the space occupied when the device is moved.

[0006] A high-pressure injector, comprising:

[0007] A column, the top of which is provided with a high-pressure injector body, the bottom of which is hinged with multiple groups of support rods along its circumference, and the bottoms of the multiple groups of support rods are all provided with universal wheels with a self-locking function;

[0008] A clamping mechanism comprising a fixed clamping plate and a movable clamping plate, wherein the fixed clamping plate is arranged on the peripheral side of the column, the movable clamping plate is located below the fixed clamping plate, and one end of the movable clamping plate is provided with a first connecting sleeve, the first connecting sleeve is sleeved on the column and can slide along the axial direction thereof; and

[0009] The driving mechanism includes a motor, a turntable and a transmission assembly. The motor is arranged on the column, and the output end is coaxially connected to the turntable. The transmission assembly is connected to the first connecting sleeve, the turntable and the multiple groups of support rods. The forward rotation of the turntable can first drive the movable splint to move upward to a preset position and then keep it stationary through the transmission assembly, and then drive the multiple groups of support rods to close and rotate upward. The reverse rotation of the turntable can first drive the multiple groups of support rods to open and rotate downward to reset through the transmission assembly, and then drive the movable splint to move downward.

[0010] The beneficial effects of the above-mentioned high-pressure injector are:

[0011] By moving the device to one side of the examination bed and making the fixed splint contact the top surface of the bed board, the movable splint is located under the bed board, and then the motor is controlled to drive the turntable to rotate forward. The turntable rotates forward through the transmission component to drive the first connecting sleeve to drive the movable splint to move upward. When the movable splint moves upward and abuts against the bottom surface of the bed board, the movable splint remains stationary. At this time, the movable splint can cooperate with the fixed splint to clamp the bed board. The device is easy to connect to the examination bed, which is convenient for the device to move with the bed and avoid pulling the injection tube. The movement is convenient and safe. After the movable splint cooperates with the fixed splint to clamp the bed board, the turntable rotates forward through the transmission component to drive the multiple groups of support rods to close and rotate upward. The multiple groups of support rods can be closed and rotated upward to separate the multiple groups of universal wheels from the ground and fold the multiple groups of support rods, thereby reducing the space occupied by the device and further reducing the space occupied by the device when it is moved.

[0012] In one embodiment, the transmission assembly includes:

[0013] A connecting column is arranged parallel to the column, the top of the connecting column is connected to the first connecting sleeve, and the bottom is provided with a dial shaft, one end of the turntable is provided with an inclined groove and a positioning ring groove, one end of the inclined groove and the positioning ring groove are coaxial with the turntable, the other end of the inclined groove is connected to one end of the positioning ring groove, and the dial shaft is slidably arranged in the inclined groove and the positioning ring groove;

[0014] A second connecting sleeve is sleeved on the column and can slide along the axial direction of the column. The second connecting sleeve is hinged to a plurality of connecting rods on its circumference, and one end of each of the plurality of connecting rods is hinged to each of the plurality of supporting rods; and

[0015] The first screw is rotatably arranged on the column and is parallel to the column. The first screw is threadedly connected to the second connecting sleeve. A bevel gear is coaxially arranged on the top end of the first screw, and a bevel gear arc segment is coaxially arranged on the other end of the turntable. When the shift shaft slides from the inclined groove into the positioning ring groove, the bevel gear engages with the bevel gear arc segment. When the turntable rotates forward, the turntable drives the inclined slot and the positioning ring slot to rotate, and the inclined slot rotates to squeeze the dial shaft to move upward, and the dial shaft moves upward and drives the first connecting sleeve to move the movable splint upward through the connecting column. When the dial shaft slides from the inclined slot to the positioning ring slot, the positioning ring slot rotates to fix the dial shaft, thereby fixing the movable splint, driving the movable splint to move upward and keep it stationary in the preset position. When the dial shaft slides from the inclined slot to the positioning ring slot, the bevel gear meshes with the bevel gear arc segment, at this time, the turntable rotates forward to drive the bevel gear arc segment to rotate and cooperate with the bevel gear to drive the first screw to rotate, and the first screw rotates and cooperates with the second connecting sleeve thread to drive the second connecting sleeve to move upward, and the second connecting sleeve moves upward and drives multiple groups of support rods to close and rotate through multiple sets of connecting rods. It is convenient to fold up multiple groups of support rods. When the turntable rotates backward, When the gear train is turned, the first gear train is turned to the left by the second gear train, and the gear train is turned to the right by the second gear train, so that the gear train can be turned to the left by the second gear train.

[0016] In one embodiment, the clamping mechanism further includes an adjustment assembly, wherein the fixed clamping plate and the movable clamping plate are respectively connected to the column and the first connecting sleeve via the adjustment assembly. Actuating the adjustment assembly separately can drive the fixed clamping plate and the movable clamping plate to slide axially along the column. By separately actuating the adjustment assembly to drive the fixed clamping plate and the movable clamping plate up and down, the relative positions of the fixed clamping plate and the movable clamping plate can be adjusted according to the height and thickness of the examination bed bed, thereby facilitating connection of the device to different types of examination beds and improving the practicality of the device.

[0017] In one embodiment, the adjustment assembly includes a second screw; a first slide groove is formed on the circumference of each of the column and the first connecting sleeve; one end of each of the fixed splint and the movable splint is slidably disposed in two sets of the first slide grooves along the axis of the column; a second screw parallel to the column is rotatably disposed in each of the two sets of the first slide grooves; and the two sets of the second screws are threadedly connected to the fixed splint and the movable splint, respectively. The fixed splint and the movable splint can be driven to slide upward or downward by rotating the second screw forward or backward to engage with the threads of the fixed splint and the movable splint, thereby conveniently driving the fixed splint and the movable splint to slide upward or downward, and the fixed splint and the movable splint can be fixed by stopping the rotation of the second screw.

[0018] In one embodiment, the bottom end of the fixed splint and the top end of the movable splint are both provided with anti-slip pads, and the bottom end of the fixed splint and the top end of the movable splint are both provided with multiple sets of T-shaped slots. Both sets of anti-slip pads are provided with multiple sets of T-shaped clamping blocks, and the multiple sets of T-shaped clamping blocks can be clamped into the multiple sets of T-shaped slots. The provision of anti-slip pads can improve the stability of the fixed splint and the movable splint in clamping the bed board and avoid clamping damage to the bed board. At the same time, the anti-slip pads are connected to the fixed splint and the movable splint by a snap-on connection, making it easy to install and remove the anti-slip pads and facilitating the replacement of the anti-slip pads of vulnerable parts.

[0019] In one embodiment, the upright post is further provided with a storage assembly comprising a storage box disposed around the upright post. A storage slot is defined at the top of the box, and partitions are alternately disposed on either side of the slot. Multiple sets of these partitions cooperate to form a curved channel, each with an opening at each end. When the device is connected to an examination bed, excess syringes can be placed within the curved channel, with their ends positioned within the two sets of openings. The storage box then stores the excess syringes, preventing them from becoming entangled or compressed.

[0020] In one embodiment, the staggered ends of the plurality of groups of partitions are each provided with a telescopic slot, and the plurality of groups of telescopic slots are each provided with an extension plate that can slide along the length direction of the partition. One end of the plurality of groups of extension plates is connected to the telescopic slot via a spring, and the other end extends outside the partition. When the syringe is pulled, the syringe located in the bending channel can squeeze the extension plate, causing the extension plate to retract into the partition and squeeze the spring. At this time, the bending channel stroke is shortened, and the syringe located in the bending channel can extend to a certain length. After the pull on the syringe disappears, the reaction force of the spring causes the extension plate to extend outward and drive the syringe to retract into the bending channel, thereby allowing the syringe to have a telescopic margin within the bending channel, thereby preventing the syringe from being broken after being stored.

[0021] In one embodiment, a placement slot is formed around the column, and a rotating shaft is provided at one end of the storage box. The rotating shaft is rotatably disposed in the placement slot so that the storage box can be rotated into the storage box. By rotating the storage box into the placement slot, the storage box can be easily stored when not in use.

[0022] In one embodiment, the storage assembly further includes a linkage assembly connecting the first connecting sleeve and the rotating shaft. When the first connecting sleeve moves upward, the linkage assembly drives the rotating shaft to rotate forward, thereby extending the storage box from the placement slot. When the first connecting sleeve moves downward, the linkage assembly drives the rotating shaft to rotate backward, thereby retracting the storage box from the placement slot. This facilitates extending the storage box from the placement slot when the device is connected to the examination bed and retracting the storage box into the placement slot when the device is separated from the examination bed.

[0023] In one embodiment, the linkage assembly includes a gear and a rack; the gear is coaxially disposed on one end of the rotating shaft, and the rack is disposed on the first connecting sleeve and meshes with the gear. The upward movement of the first connecting sleeve drives the rack upward, and the upward movement of the rack meshes with the gear, thereby driving the gear to rotate forward. The forward rotation of the gear drives the rotating shaft forward. The downward movement of the first connecting sleeve drives the rack downward, and the downward movement of the rack meshes with the gear, thereby driving the gear to rotate reversely. The reverse rotation of the gear drives the rotating shaft to rotate reversely, making it easy to drive the rotating shaft forward or reversely. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0040] See also Figure 1 、 Figure 2 and Figure 5 In one embodiment, a high-pressure injector includes a column 10, a clamping mechanism and a driving mechanism.

[0041] The high-pressure injector body 1 is mounted on the top of the column 10. Multiple sets of support rods 101 are hingedly connected to the bottom of the column 10 along its circumference. Each set of support rods 101 is equipped with a self-locking universal wheel 102 at its bottom. The clamping mechanism includes a fixed clamping plate 20 and a movable clamping plate 201. The fixed clamping plate 20 is mounted on the side of the column 10. The movable clamping plate 201 is located below the fixed clamping plate 20 and has a first connecting sleeve 202 at one end. The first connecting sleeve 202 is mounted on the column 10 and can slide along its axial direction. The driving mechanism includes a motor 30, a turntable 301 and a transmission assembly. The motor 30 is arranged on the column 10, and the output end is coaxially connected to the turntable 301. The transmission assembly is connected to the first connecting sleeve 202, the turntable 301 and the multiple groups of support rods 101. The turntable 301 can drive the movable splint 201 to move upward to a preset position and then keep it stationary through the transmission assembly, and then drive the multiple groups of support rods 101 to close and rotate upward. The turntable 301 can be reversed to drive the multiple groups of support rods 101 to open and rotate downward through the transmission assembly and then reset, and then drive the movable splint 201 to move downward.

[0042] In the above embodiment, by moving the device to one side of the examination bed and making the fixed splint 20 contact the top surface of the bed board 2, the movable splint 201 is located below the bed board 2, and then controlling the motor 30 to drive the turntable 301 to rotate forward, the turntable 301 rotates forward and drives the first connecting sleeve 202 through the transmission assembly to drive the movable splint 201 to move upward. When the movable splint 201 moves upward and abuts against the bottom surface of the bed board 2, the movable splint 201 remains stationary. At this time, the movable splint 201 cooperates with the fixed splint 20 to clamp the bed board. 2. The device is easy to connect to the examination bed, so that the device can be moved with the bed to avoid pulling the injection tube (not shown). The movement is convenient and safe. After the movable splint 201 and the fixed splint 20 cooperate to clamp the bed board 2, the turntable 301 rotates forward through the transmission assembly to drive the multiple groups of support rods 101 to close and rotate upward. The multiple groups of support rods 101 close and rotate upward to separate the multiple groups of universal wheels 102 from the ground and fold the multiple groups of support rods 101, thereby reducing the space occupied by the device and further reducing the space occupied when the device is moved.

[0043] When the device needs to be separated from the examination bed, the motor 30 is controlled to drive the turntable 301 in reverse. The turntable 301 rotates downward through the transmission assembly, first driving the multiple sets of support rods 101 to expand and rotate downward. The downward expansion and rotation of the multiple sets of support rods 101 causes the multiple sets of universal wheels 102 to contact the ground. After the multiple sets of universal wheels 102 contact the ground, the turntable 301 rotates downward through the transmission assembly to drive the first connecting sleeve 202 to move the movable clamping plate 201 downward. The movable clamping plate 201 moves downward and separates from the bottom surface of the bed board 2. At this point, the movable device can be separated from the examination bed. This facilitates separation of the device from the examination bed, and the multiple sets of support rods 101 do not need to be separately operated, further improving the convenience of use of the device. At the same time, when the device moves with the bed, the universal wheels 102 separate from the ground, which can increase the service life of the universal wheels 102. It can be understood that the movable clamping plate 201 moves upward to a predetermined position, that is, the movable clamping plate 201 moves upward to abut the bottom surface of the bed board 2.

[0044] Specifically in the above embodiment, a limit block 2021 is provided on the first connecting sleeve 202, and a second slide groove 104 is provided on the side of the column 10. The limit block 2021 is slidable along the axial direction of the column 10 within the second slide groove 104. The cooperation between the limit block 2021 and the second slide groove 104 can prevent the first connecting sleeve 202 from rotating when sliding.

[0045] See also Figures 1 to 5 In one embodiment, the transmission assembly includes a connecting column 302, a second connecting sleeve 303, and a first screw 304. The connecting column 302 is arranged parallel to the column 10. The top of the connecting column 302 is connected to the first connecting sleeve 202, and the bottom is provided with a shifting shaft 3021. One end of the turntable 301 is provided with an inclined groove 3011 and a positioning ring groove 3012. One end of the inclined groove 3011 and the positioning ring groove 3012 are both coaxial with the turntable 301. The other end of the inclined groove 3011 is connected to one end of the positioning ring groove 3012. The shifting shaft 3021 is slidably disposed within the inclined groove 3011 and the positioning ring groove 3012. The second connecting sleeve 303 is slidably mounted on the column 10 along the axial direction of the column 10. Multiple groups of connecting rods 3031 are hingedly connected to the circumference of the second connecting sleeve 303. One end of each group of connecting rods 3031 is hingedly connected to multiple groups of support rods 101. The first screw 304 is rotatably arranged on the column 10 and is parallel to the column 10. The first screw 304 is threadedly connected to the second connecting sleeve 303. A bevel gear 305 is coaxially arranged on the top of the first screw 304, and a bevel gear arc segment 306 is coaxially arranged on the other end of the turntable 301. When the shift shaft 3021 slides from the inclined groove 3011 to the positioning ring groove 3012, the bevel gear 305 engages with the bevel gear arc segment 306.

[0046] In the above embodiment, when the turntable 301 rotates forward, the turntable 301 drives the inclined groove 3011 and the positioning ring groove 3012 to rotate, and the inclined groove 3011 rotates to squeeze the dial shaft 3021 to move upward. The dial shaft 3021 moves upward and drives the first connecting sleeve 202 to drive the movable splint 201 to move upward through the connecting column 302. When the dial shaft 3021 slides from the inclined groove 3011 to the positioning ring groove 3012, the positioning ring groove 3012 rotates to fix the dial shaft 3021, thereby fixing the movable splint 201 and driving the movable splint 201 to move upward. The first screw rod 304 is rotated by the turntable 3011 and the second connecting sleeve 303 is screwed together, and the second connecting sleeve 303 is screwed together, so that the second connecting sleeve 303 moves upward. The second connecting sleeve 303 moves upward and drives the multiple groups of support rods 101 to close and rotate upward through the multiple groups of connecting rods 3031, and the multiple groups of support rods 101 are folded and rotated. The multiple sets of support rods 101 are convenient. When the turntable 301 is reversed, the turntable 301 drives the bevel gear arc segment 306 to rotate in the opposite direction and cooperates with the bevel gear 305 to drive the first screw 304 to rotate in the opposite direction. The first screw 304 rotates in the opposite direction and cooperates with the second connecting sleeve 303 thread to drive the second connecting sleeve 303 to move downward. The downward movement of the second connecting sleeve 303 can drive the multiple sets of support rods 101 to open and rotate downward through the multiple sets of connecting rods 3031, and make the multiple sets of universal wheels 102 contact the ground, driving the multiple sets of support rods 101 to open and rotate downward for easy reset. , and after the multiple groups of support rods 101 are reset, the bevel gear arc segment 306 rotates in the opposite direction and separates from the bevel gear 305, and the dial shaft 3021 slides from the positioning ring groove 3012 to the inclined groove 3011. At this time, the turntable 301 reverses and drives the dial shaft 3021 to move downward through the inclined groove 3011. The dial shaft 3021 moves downward and drives the first connecting sleeve 202 through the connecting column 302 to drive the movable splint 201 to move downward. The movable splint 201 moves downward and can be separated from the bottom surface of the bed board 2, thereby canceling the connection between the device and the examination bed, which is convenient for canceling the connection between the device and the examination bed.

[0047] See also Figure 1 and Figure 4 In one embodiment, the clamping mechanism further includes an adjusting component, wherein the fixed splint 20 and the movable splint 201 are respectively connected to the column 10 and the first connecting sleeve 202 through the adjusting component, and the adjusting component can be driven to drive the fixed splint 20 and the movable splint 201 to slide axially along the column 10.

[0048] In the above embodiment, by driving the adjustment assembly to drive the fixed splint 20 and the movable splint 201 to slide up and down, the relative positions of the fixed splint 20 and the movable splint 201 can be adjusted according to the height and thickness of the examination bed bed 2, thereby facilitating the connection of the device with examination beds of different models and improving the practicality of the device.

[0049] See also Figure 4 In one embodiment, the adjustment component includes a second screw 203; a first sliding groove 204 is opened on the side of the column 10 and the first connecting sleeve 202, and one end of the fixed splint 20 and the movable splint 201 can be slid along the axial direction of the column 10 in the two groups of first sliding grooves 204 respectively, and the second screw 203 parallel to the column 10 is rotatably arranged in the two groups of first sliding grooves 204, and the two groups of second screws 203 are threadedly connected to the fixed splint 20 and the movable splint 201 respectively.

[0050] In the above embodiment, the fixed splint 20 and the movable splint 201 can be driven to slide upward or downward by rotating the second screw 203 forward or reversely and engaging with the fixed splint 20 and the movable splint 201 threads. It is convenient to drive the fixed splint 20 and the movable splint 201 to slide upward or downward, and the fixed splint 20 and the movable splint 201 can be fixed by stopping the rotation of the second screw 203.

[0051] See also Figure 1 and Figure 4 In one embodiment, anti-slip pads 205 are provided at the bottom end of the fixed splint 20 and the top end of the movable splint 201, and multiple groups of T-shaped slots 206 are provided at the bottom end of the fixed splint 20 and the top end of the movable splint 201. Multiple groups of T-shaped blocks 2051 are provided on both groups of anti-slip pads 205, and the multiple groups of T-shaped blocks 2051 can be clamped in the multiple groups of T-shaped slots 206.

[0052] In the above embodiment, the anti-slip pad 205 is provided to improve the stability of the fixed splint 20 and the movable splint 201 in clamping the bed board 2, and to avoid clamping damage to the bed board 2. At the same time, the anti-slip pad 205 is snap-connected to the fixed splint 20 and the movable splint 201, and the anti-slip pad 205 is easy to install and remove, and the replacement of the consumable anti-slip pad 205 is convenient.

[0053] See also Figure 2 、 Figure 6 and Figure 7 In one embodiment, a storage component is further provided on the column 10, and the storage component includes a storage box 40. The storage box 40 is provided on the side of the column 10, and a storage groove is opened at the top of the storage box 40. Partitions 401 are alternately arranged on both sides of the storage groove. Multiple groups of partitions 401 cooperate to form a bending channel 402, and openings 4021 are opened at both ends of the bending channel 402.

[0054] In the above embodiment, when the device is connected to the examination bed, the excess syringes can be placed in the bent channel 402 and the two ends of the syringes can be respectively located in the two groups of openings 4021. At this time, the storage box 40 can store the excess syringes to prevent the syringes from being entangled or compressed.

[0055] See also Figure 6 and Figure 7 In one embodiment, the staggered ends of multiple groups of partitions 401 are provided with telescopic grooves 4011, and the multiple groups of telescopic grooves 4011 are provided with extension plates 403 that can slide along the length direction of the partitions 401. One end of the multiple groups of extension plates 403 is connected to the telescopic groove 4011 through a spring 404, and the other end extends to the outside of the partition 401.

[0056] In the above embodiment, when the injection tube is pulled, the injection tube located in the bending channel 402 can squeeze the extension plate 403 so that the extension plate 403 retracts into the partition 401 and squeezes the spring 404. At this time, the stroke of the bending channel 402 becomes shorter, and the injection tube located in the bending channel 402 can be extended to a certain length. After the pull on the injection tube disappears, the reaction force of the spring 404 causes the extension plate 403 to extend outward and drives the injection tube to retract into the bending channel 402, so that the injection tube has a stretch margin in the bending channel 402, thereby avoiding the phenomenon of the injection tube being pulled apart after being stored.

[0057] See also Figure 1 、 Figure 2 、 Figure 6 and Figure 7 In one embodiment, a placement slot 103 is formed on the side of the column 10, and a rotating shaft 405 is provided at one end of the storage box 40. The rotating shaft 405 is rotatably disposed in the placement slot 103 so that the storage box 40 can be rotated into the storage box 40. By rotating the storage box 40 into the placement slot 103, the storage box 40 can be stored when not in use.

[0058] In addition to the above embodiment, the storage assembly further includes a linkage assembly that connects the first connecting sleeve 202 and the rotating shaft 405. When the first connecting sleeve 202 moves upward, the linkage assembly drives the rotating shaft 405 to rotate forward, thereby extending the storage box 40 from the placement slot 103. When the first connecting sleeve 202 moves downward, the linkage assembly drives the rotating shaft 405 to rotate reversely, thereby retracting the storage box 40 into the placement slot 103. Specifically, the linkage assembly includes a gear 406 and a rack 407. The gear 406 is coaxially disposed on one end of the rotating shaft 405. The rack 407 is disposed on the first connecting sleeve 202 and meshes with the gear 406.

[0059] When the first connecting sleeve 202 drives the movable splint 201 to move upward to clamp the bed board 2, the first connecting sleeve 202 drives the rack 407 to move upward, and the rack 407 moves upward to engage with the gear 406 to drive the gear 406 to rotate forward. The forward rotation of the gear 406 can drive the rotating shaft 405 to rotate forward, so that the storage box 40 extends out of the placement slot 103, so that the storage box 40 is automatically extended out of the placement slot 103 when the device is connected to the examination bed. When the first connecting sleeve 202 drives the movable splint 201 to move downward to cancel the clamping of the bed board 2, the first connecting sleeve 202 moves downward to drive the rack 407 to move downward, and the rack 407 moves downward to engage with the gear 406 to drive the gear 406 to reverse. The reverse rotation of the gear 406 can drive the rotating shaft 405 to reverse, so that the storage box 40 is retracted into the placement slot 103, so that the storage box 40 is automatically stored in the placement slot 103 when the device is separated from the examination bed.

[0060] The specific implementation of the above-mentioned high-pressure injector is as follows:

[0061] When the examination bed needs to be moved to move the patient, the device is first moved to one side of the examination bed and the fixed splint 20 is in contact with the top surface of the bed board 2. The movable splint 201 is located under the bed board 2. Then the motor 30 is controlled to drive the turntable 301 to rotate forward. The turntable 301 rotates forward to drive the inclined slot 3011 and the positioning ring slot 3012 to rotate. The inclined slot 3011 rotates to squeeze the dial shaft 3021 to move upward. The dial shaft 3021 moves upward and drives the first connecting sleeve 202 through the connecting column 302 to drive the movable splint 201 to move upward. When the movable splint 201 moves upward and abuts against the bottom surface of the bed board 2 and cooperates with the fixed splint 20 to clamp the bed board 2, the dial shaft 3021 slides from the inclined groove 3011 to the positioning ring groove 3012. The positioning ring groove 3012 is rotated to fix the dial shaft 3021, thereby fixing the movable splint 201, and then fixing the device on the examination bed. The device is easy to connect to the examination bed and can be driven to move by moving the examination bed. There is no need to move the device separately to avoid pulling the injection tube. The movement is convenient and safe.

[0062] When the first screw 304 is rotated, the first screw 304 is rotated and engaged with the second connecting sleeve 303, thereby driving the second connecting sleeve 303 to move upward. The second connecting sleeve 303 moves upward and drives the multiple support rods 101 to close and rotate upward through the multiple connecting rods 3031. It is convenient to fold the multiple support rods 101, thereby reducing the occupied space of the device and reducing the occupied space when the device is moved. In addition, the multiple support rods 101 can be automatically folded after the device is connected to the examination bed, further improving the convenience of use of the device. At the same time, the upward folding movement of the multiple support rods 101 can drive the multiple universal wheels 102 to separate from the ground, that is, when the device moves with the bed, the universal wheels 102 do not work, thereby increasing the service life of the universal wheels 102.

[0063] When the device needs to be separated from the examination bed, the motor 30 is controlled to drive the turntable 301 to reverse, and the reverse rotation of the turntable 301 drives the bevel gear arc segment 306 to rotate in the opposite direction and cooperate with the bevel gear 305 to drive the first screw 304 to rotate in the opposite direction. The first screw 304 rotates in the opposite direction and cooperates with the second connecting sleeve 303 threadedly to drive the second connecting sleeve 303 to move downward. The downward movement of the second connecting sleeve 303 can drive the multiple groups of support rods 101 to open and rotate downward through the multiple groups of connecting rods 3031, and make the multiple groups of universal wheels 102 contact with the ground, thereby resetting the multiple groups of support rods Rod 101, and after the multiple groups of support rods 101 are reset, the bevel gear arc segment 306 separates from the bevel gear 305, and the dial shaft 3021 slides from the positioning ring groove 3012 to the inclined groove 3011. At this time, the turntable 301 reverses and drives the dial shaft 3021 to move downward through the inclined groove 3011. The dial shaft 3021 moves downward and drives the first connecting sleeve 202 to drive the movable splint 201 to move downward through the connecting column 302. The movable splint 201 moves downward to separate from the bottom surface of the bed board 2, thereby canceling the connection between the device and the examination bed, which is convenient for canceling the connection between the device and the examination bed.
