Releasing the limit on the pulley means that the equipment can move freely or adjust its position.

[0010] According to the above technical solution, the free end of the second telescopic elastic rod is fixedly connected to the surface of the pulley, the surface of the connecting rod pressure plate is fixedly connected, and the sleeve plate slides through the surface of the base, which provides higher flexibility and facilitates doctors or patients to adjust the position of the device during treatment, ensuring that the device can easily adapt to different treatment environments. According to the above technical solution, the brake plate is made of rubber, the end of the inclined rod close to the pulley is set to inclined plane four, and the surface of the limit plate is set to inclined plane five, which fixes the pulley. At this time, the pulley cannot rotate, which improves the stability of the device in an unconnected state, avoids sliding or rolling due to external forces and causing improper situations, avoids unnecessary movement of the equipment, and ensures that the equipment remains stable during use.

The retractable design of the protective plate makes the operation of the equipment more convenient, and the equipment can move freely without being hindered by the existence of the protective plate, which helps to improve the flexibility of the equipment. When the equipment is moved, it is easier to adjust the position or perform cleaning and maintenance operations.

[0012] According to the above technical solution, the free end of the telescopic elastic rod three is fixedly connected to the protective plate, the surface of the inclined block two is set as inclined surface six, the end of the inclined plate close to the inclined block two is set as inclined surface seven, the surface of the protective plate is provided with a slot, the contact plate is fitted with the slot, the surface of the extrusion plate is set as inclined surface eight, the free end of the telescopic elastic rod four is fixedly connected to the surface of the protective plate, the elastic coefficient of the telescopic elastic rod three is greater than that of the telescopic elastic rod four, the surface of the end of the pressure plate away from the anti-roll plate is set as inclined surface nine, which drives the anti-roll plate to move downward to support the base. When the external force is too large, the contact plate has been fitted with the protective plate and the force will push the protective plate to move toward the direction close to the base.

[0013] The present invention provides a portable blood purification device having the following beneficial effects: (1) The portable blood purification device moves by deforming and restoring the telescopic spring rod and pushing the inclined block to move to limit the trapezoidal block. At this time, the placement table limits the position of the purifier, improving the stability of the device during the transfer process, avoiding bumps or damage to the device due to improper fixation, and effectively preventing the device from accidentally moving or tilting during the transfer process. This is crucial to the stability of the blood purification device, reducing the pressure and wear of the internal components of the device, and helping to extend the service life of the device. The purifier can be pulled upward. When the device needs to travel with a vehicle, the size of the device can be changed by adjusting the telescopic column to adapt to the internal space of the vehicle, thereby improving the adaptability of the device and improving the passability of the device in different environments. (2) The portable blood purification device drives the inclined rod to move by moving the sleeve downward. The inclined rod moves downward to contact and squeeze the limit plate to move away from the pulley. At the same time, the movement of the limit plate drives the brake plate to move to release the limit on the pulley. At this time, the pulley can rotate, and the pulley can be changed to rotate according to whether the purification machine is connected to the placement table. Releasing the limit on the pulley means that the device can be freely moved or adjusted, providing higher flexibility, making it easier for doctors or patients to adjust the position of the device during treatment, and ensuring that the device can easily adapt to different treatment environments. (3) The portable blood purification device moves the limit plate toward the pulley through the deformation recovery of the telescopic spring rod. At this time, the brake plate contacts the pulley under the action of the limit plate and fixes the pulley. At this time, the pulley cannot rotate, which improves the stability of the device in the unconnected state and avoids sliding or rolling due to external forces, thereby preventing improper situations and unnecessary movement of the device, ensuring that the device remains stable during use. The inclined rod moves downward to drive the connecting rod to move, and the movement of the connecting rod drives the pressure plate to move. At this time, the movement of the pressure plate will pump the lubricating oil accumulated in the lubrication box out through the oil pipe to lubricate the pulley, which can reduce the friction between the pulley and the contact parts, thereby reducing wear and extending the service life of the equipment. (4) The portable blood purification device moves toward the sliding rod through the movement of the inclined block 2 and the inclined plate. The movement of the inclined block 2 drives the free end of the telescopic fixed plate to retract, so that the outer protective plate can be retracted during the connection and transfer process, and opened when the purification machine is separated from the placement table, thereby avoiding the influence of the outer components on the passability and adaptability of the device during the transfer process. The retractable design of the protective plate makes the operation of the device more convenient. The device can move freely without being hindered by the existence of the protective plate, which helps to improve the flexibility of the device. When the device is moved, it can be more easily adjusted or cleaned and maintained.(5) The portable blood purification device drives the extrusion plate to move by moving the fixed rod. The extrusion plate moves to contact and squeeze the pressure plate to move downward. At this time, the pressure plate moves downward under the action of the extrusion plate, driving the anti-roll plate to move downward to support the base. When the external force is too large, the contact plate has been in contact with the protective plate. The force will push the protective plate to move closer to the base, driving the anti-roll plate to support a longer downward travel, providing additional protection for the equipment and effectively extending the service life of the equipment.

The inner wall of the base 33 is provided with a fixing device for fixing and limiting the purifier 1, and the fixing device includes a sliding rod 34, and the sliding rod 34 slides A spring 35 is arranged between the sliding rod 34 and the placing platform 31, a C-shaped plate 36 is fixedly installed on the inner wall of the placing platform 31, a telescopic elastic rod 37 is fixedly installed on the surface of the C-shaped plate 36, an inclined block 38 is fixedly installed on the free end of the telescopic elastic rod 37, a fixed plate 39 is fixedly installed on the surface of the purifier 1, a trapezoidal block 310 is fixedly installed on the surface of the fixed plate 39, the fixed plate 39 moves downward to drive the trapezoidal block 310 to move downward, the trapezoidal block 310 moves downward to contact and squeeze the inclined block 38 to move towards the direction close to the telescopic elastic rod 37, a sliding block 311 is slidably installed on the surface of the fixed plate 39, and a pulley 312 is fixedly installed on the bottom of the base 33.

[0018] The shoulder strap 21 is set to be adjustable, a spare anticoagulant tank 23 is fixedly installed on the surface of the placement table 31, the surface of the inclined block 38 is set to be inclined plane 1, the trapezoidal block 310 moves downward to contact and squeeze the inclined block 38 to move towards the direction close to the telescopic elastic rod 37, thereby releasing the restriction on the C-shaped plate 36.

[0019] The surface of the trapezoidal block 310 is set as inclined plane 2, the telescopic elastic rod 37 is deformed and moves to restore and push the inclined block 38 to move to limit the trapezoidal block 310, the surface of the sliding block 311 is set as inclined plane 3, the surface of the placing table 31 is opened with a circular groove, and the sliding rod 34 fits with the circular groove.

[0020] When this embodiment is working: Under normal circumstances, this device only needs to be carried by the handle or shoulder strap 21. When it is needed to be used for a long distance, the purifier 1 is placed on the top of the placement table 31. At this time, the purifier 1 moves downward to drive the fixed plate 39 to move downward. At the same time, the fixed plate 39 moves downward to drive the trapezoidal block 310 to move downward. The trapezoidal block 310 moves downward to contact and squeeze the inclined block 38 to move in the direction close to the telescopic elastic rod 37, thereby releasing the restriction on the C-shaped plate 36. Then the fixed plate 39 passes through.

At this time, the purifier 1 can be pulled upward. When the equipment needs to travel with the vehicle, the size of the equipment can be changed by adjusting the telescopic column 32 to adapt to the internal space of the vehicle, thereby improving the adaptability of the equipment and the passability of the equipment in different environments. See also Figure 1-Figure 9 On the basis of the above embodiment, in another embodiment of the present invention, the circumferential surface of the sliding rod 34 is provided with a limiting device for limiting the position of the pulley 312 when the purifier 1 is docked. The limiting device includes a sleeve plate 41, which is fixedly mounted on the circumferential surface of the sliding rod 34, a limiting plate 42 is fixedly mounted on the surface of the pulley 312, a brake plate 43 is fixedly mounted on the surface of the limiting plate 42, a telescopic elastic rod 44 is fixedly mounted on the surface of the limiting plate 42, an inclined rod 45 is fixedly mounted on the surface of the sleeve plate 41, and a bottom A lubrication box 46 is fixedly installed at the bottom of the seat 33, and an oil pipe 47 is fixedly passed through the bottom of the lubrication box 46. A connecting rod 48 is fixedly installed on the surface of the inclined rod 45, and a pressure plate 49 is slidably installed on the inner wall of the lubrication box 46. The inclined rod 45 moves downward to drive the connecting rod 48 to move, and the movement of the connecting rod 48 drives the pressure plate 49 to move. At this time, the movement of the pressure plate 49 pumps out the lubricating oil accumulated in the lubrication box 46 through the oil pipe 47 to lubricate the pulley 312, and a closing plate 410 is fixedly installed on the circumferential surface of the connecting rod 48.

[0021] The free end of the telescopic spring rod 44 is fixedly connected to the surface of the pulley 312, the connecting rod 48 is fixedly connected to the surface of the pressure plate 49, the sleeve plate 41 slides through the surface of the base 33, the sliding rod 34 moves downward to drive the sleeve plate 41 to move, and the sleeve plate 41 moves downward to drive the inclined rod 45 to move. The brake plate 43 is made of rubber, the end of the inclined rod 45 close to the pulley 312 is set as inclined surface 4, the surface of the limiting plate 42 is set as inclined surface 5, and the brake plate 43 contacts the pulley 312 under the action of the limiting plate 42 and fixes the pulley 312.

[0022] The surface of the sleeve plate 41 is provided with an anti-dumping device for preventing the base 33 from tipping over. The anti-dumping device includes a telescopic fixed plate 51, which is fixedly mounted on the surface of the sleeve plate 41. A protective plate 52 is fixedly mounted on the free end of the telescopic fixed plate 51. A telescopic elastic rod 3 53 is slidably mounted on the surface of the base 33. An inclined block 2 54 is fixedly mounted on the surface of the telescopic fixed plate 51. An inclined plate 55 is fixedly mounted on the surface of the base 33. A fixed rod 56 slides through the surface of the protective plate 52. A contact plate 57 is fixedly mounted on the end of the fixed rod 56 away from the base 33. An extrusion plate 58 is fixedly mounted on the end of the fixed rod 56 close to the base 33. A telescopic elastic rod 4 59 is fixedly mounted on the surface of the extrusion plate 58. A pressure plate 510 is slidably mounted on the surface of the base 33. The movement of the fixed rod 56 drives the extrusion plate 58 to move. The extrusion plate 58 moves to contact and squeeze the pressure plate 510 to move downward. An anti-tilt plate 511 is fixedly mounted on the end of the pressure plate 510 away from the base 33. A telescopic elastic rod 512 is fixedly mounted on the surface of the anti-tilt plate 511.

[0023] The free end of the telescopic elastic rod three 53 is fixedly connected to the protective plate 52, the surface of the inclined block two 54 is set as inclined surface six, and the end of the inclined plate 55 close to the inclined block two 54 is set as inclined surface seven. A slot is opened on the surface of the protective plate 52, and the contact plate 57 fits with the slot. The external force contacts and pushes the contact plate 57 to move in the direction close to the base 33. The movement of the contact plate 57 drives the fixed rod 56 to move. The surface of the extrusion plate 58 is set as inclined surface eight. The free end of the telescopic elastic rod four 59 is fixedly connected to the surface of the protective plate 52. The elastic coefficient of the telescopic elastic rod three 53 is greater than that of the telescopic elastic rod four 59. The surface of the end of the pressure plate 510 away from the anti-tilt plate 511 is set as inclined surface nine.

[0024] When the present embodiment is working, when the purifier 1 moves downward, contacts and squeezes the sliding rod 34 to move downward, and at the same time, the sliding rod 34 moves downward to drive the sleeve plate 41 to move. At this time, the sleeve plate 41 moves downward to drive the inclined rod 45 to move. The inclined rod 45 moves downward to contact and squeeze the limiting plate 42 to move in the direction away from the pulley 312. At the same time, the limiting plate 42 moves to drive the brake plate 43 to move to release the limit on the pulley 312. At this time, the pulley 312 can rotate, so that the pulley 312 changes the rotation of the pulley 312 according to whether the purifier 1 is connected to the placement table 31. Releasing the limit on the pulley means that the equipment can be freely moved or adjusted in position, which provides higher flexibility, facilitates the doctor or patient to adjust the position of the equipment during treatment, and ensures that the equipment can easily adapt to different treatment environments. When the staff takes away the purifier 1, the limiting plate 42 loses the inclined rod 45. Its function is that the deformation of the telescopic elastic rod 44 is restored to pull the limit plate 42 to move in the direction close to the pulley 312. At this time, the brake plate 43 contacts the pulley 312 under the action of the limit plate 42 and fixes the pulley 312. At this time, the pulley 312 cannot rotate, which improves the stability of the equipment in the unconnected state, avoids sliding or rolling due to external forces and thus causes improper situations, avoids unnecessary movement of the equipment, and ensures that the equipment remains stable during use. At the same time, the inclined rod 45 moves downward under the action of the sleeve plate 41, and the downward movement of the inclined rod 45 drives the connecting rod 48 to move, and the movement of the connecting rod 48 drives the pressure plate 49 to move. At this time, the movement of the pressure plate 49 pumps the lubricating oil accumulated in the lubrication box 46 out through the oil pipe 47 to lubricate the pulley 312, which can reduce the friction between the pulley and the contact parts, thereby reducing wear and tear and extending the service life of the equipment. When the sleeve plate 41 moves under the action of the sliding rod 34, it drives the telescopic fixing plate 51 to move upward, and the telescopic fixing plate 51 moves to drive the protective plate 52 to move upward to protect the base 33. When the purifier 1 is connected to the placement table 31, it drives the telescopic fixing plate 51 to move downward. At the same time, the telescopic fixing plate 51 moves downward to drive the inclined block 2 54 to move. The inclined block 2 54 moves to contact and move in the direction close to the sliding rod 34 under the action of the inclined plate 55. The inclined block 2 54 moves to drive the free end of the telescopic fixing plate 51 to shrink, so that the outer protective plate 52 will be retracted during the connection transfer process, and opened when the purifier 1 is separated from the placement table 31, so as to avoid the outer components affecting the passability and adaptability of the equipment during the transfer process. The retractable design of the protective plate makes the operation of the equipment more convenient, and the equipment can move freely without being affected by the presence of the protective plate. This helps to improve the flexibility of the equipment. When the equipment is moved, it is easier to adjust its position or perform operations such as cleaning and maintenance. When the base 33 that is not connected to the purifier 1 is subjected to external force, the external force contacts and pushes the contact plate 57 to move in the direction close to the base 33. The movement of the contact plate 57 drives the fixed rod 56 to move. At the same time, the movement of the fixed rod 56 drives the extrusion plate 58 to move. The extrusion plate 58 moves, contacts and squeezes the pressure plate 510 to move downward. At this time, the pressure plate 510 moves downward under the action of the extrusion plate 58, driving the anti-roll plate 511 to move downward to support the base 33. When the external force is too large, the contact plate 57 has been in contact with the protective plate 52, and the force will push the protective plate 52 to move in the direction close to the base 33, driving the anti-roll plate 511 to support the downward stroke for a longer time, providing additional protection for the equipment and effectively extending the service life of the equipment.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
