The surface of the inclined block one is set as a first inclined surface, effectively preventing accidental movement or tilting of the device during the transfer process, which is crucial for the stability of the blood purification device, reducing the pressure and wear on the internal components of the device, and helping to extend the service life of the device.

[0008] According to the above technical solution, the surface of the first trapezoidal block is set as a second inclined surface. The surface of the sliding block is set as a third inclined surface. A circular groove is opened on the surface of the placement table. The sliding rod fits with the circular groove.

[0013] According to the above technical solution, the free end of the telescopic elastic rod three is fixedly connected to the protective plate.

When the external force is too large, after the contact plate has fit with the protective plate, the force will push the protective plate to move towards the base.

[0014] The present invention provides a portable blood purification device. It has the following beneficial effects:

[0015] (1)The portable blood purification device limits the trapezoidal block 1 by the deformation and restoration movement of the telescopic spring rod 1 to drive the inclined block 1 to move, and at this time, the placement table limits the purifier, improving the stability of the device during the transfer process, avoiding bumps or damage to the device caused by improper fixation, effectively preventing accidental movement or tilting of the device during the transfer process. This is crucial for the stability of the blood purification device, reducing the pressure and wear on the internal components of the device, and helping to extend the service life of the device. Just pull the purifier 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, improving the adaptability of the device and its passability in different environments. (2) The portable blood purification device drives the inclined rod to move by the downward movement of the sleeve plate. The inclined rod moves downward to contact and squeeze the limiting plate to move away from the pulley. At the same time, the movement of the limiting plate drives the brake plate to move to release the limit on the pulley. At this time, the pulley can rotate, realizing whether the pulley rotates according to whether the purifier is connected to the placement table. Releasing the limit on the pulley means that the device can move freely or adjust its position, providing higher flexibility and facilitating doctors or patients to adjust the position of the device during the treatment process to ensure that the device can easily adapt to different treatment environments. (3) The portable blood purification device pulls the limiting plate to move towards the pulley by the deformation and restoration of the telescopic spring rod 2. At this time, the brake plate contacts the pulley under the action of the limiting plate and fixes and limits the pulley. At this time, the pulley cannot rotate, improving the stability of the device in the unconnected state, avoiding sliding or rolling under the influence of external forces and causing improper situations, avoiding unnecessary movement of the device, and ensuring the stability of the device during use. The inclined rod moves downward to drive the connecting rod to move, and the connecting rod moves to drive the pressing plate to move. At this time, the pressing plate moves to pump out the lubricating oil accumulated inside the lubricating box through the oil delivery pipe to lubricate the pulley, which can reduce the friction between the pulley and the contacting parts, thereby reducing wear and extending the service life of the device. (4) The portable blood purification device moves the inclined block 2 to contact and move towards the sliding rod under the action of the inclined plate. The movement of the inclined block 2 drives the free end of the telescopic fixing plate to contract, realizing that the outer protective plate will be retracted during the transfer process of the connection and opened when the purifier is separated from the placement table, avoiding the influence of the outer components on the passability and adaptability of the device during the transfer process, and the retraction design of the protective plate makes the operation of the device more convenient. The device can move freely without being hindered by the presence of the protective plate, which helps to improve the flexibility of the device. When moving the device, it is easier to adjust the position or perform cleaning and maintenance operations, etc.(5)The portable blood purification device drives the extrusion plate to move through the movement of the fixed rod. The movement of the extrusion plate contacts and squeezes the pressure plate to move downward. At this time, the pressure plate drives the anti-tilting plate to move downward under the action of the extrusion plate to support the base. When the external force is too large, after the contact plate has been attached to the protection plate, the force will push the protection plate to move towards the base, driving the anti-tilting plate to support downward for a longer stroke, providing additional protection for the device and effectively extending the service life of the device.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-9 An embodiment of the present invention is: A portable blood purification device includes a purifier 1 and a placing table 31. A shoulder strap 21 is fixedly installed on the surface of the purifier 1, a hanging pipe 22 is fixedly installed on the surface of the purifier 1, an anticoagulation tank 23 is fixedly installed on the surface of the purifier 1, a switch 24 is fixedly installed on the surface of the purifier 1, a splint 25 is fixedly installed on the surface of the purifier 1, a syringe pump 26 is fixedly installed on the surface of the purifier 1. A telescopic column 32 is fixedly installed at the bottom of the placing table 31, and a base 33 is fixedly installed at the end of the telescopic column 32 away from the placing table 31. A fixing device for fixing and restricting the purifier 1 is arranged on the inner wall of the base 33. The fixing device includes a sliding rod 34, the sliding rod 34 is slidably installed on the inner wall of the placing table 31, a spring 35 is arranged between the sliding rod 34 and the placing table 31. A C-shaped plate 36 is fixedly installed on the inner wall of the placing table 31, a first telescopic elastic rod 37 is fixedly installed on the surface of the C-shaped plate 36, and a first inclined block 38 is fixedly installed at the free end of the first telescopic elastic rod 37. A fixed plate 39 is fixedly installed on the surface of the purifier 1, a first trapezoidal block 310 is fixedly installed on the surface of the fixed plate 39. When the fixed plate 39 moves downward, it drives the first trapezoidal block 310 to move downward. When the first trapezoidal block 310 moves downward, it contacts and presses the first inclined block 38 to move in the direction close to the first 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 at the bottom of the base 33.

[0028] The shoulder strap 21 is set to be adjustable. A spare anticoagulation tank 23 is fixedly installed on the surface of the placement table 31. The surface of the first inclined block 38 is set as the first inclined surface. The first trapezoidal block 310 moves downward to contact and squeeze the first inclined block 38 to move in the direction close to the first telescopic elastic rod 37, releasing the restriction on the C-shaped plate 36.

[0029] The surface of the first trapezoidal block 310 is set as the second inclined surface. The first telescopic elastic rod 37 deforms and restores its movement and pushes the first inclined block 38 to move to limit the first trapezoidal block 310. The surface of the sliding block 311 is set as the third inclined surface. A circular groove is formed on the surface of the placement table 31, and the sliding rod 34 fits with the circular groove.

[0030] When this embodiment works: Under normal circumstances, this device only needs to be carried by the handle or the shoulder strap 21. When there is a long-distance use requirement, the purifier 1 is placed on the top of the placement table 31. At this time, the purifier 1 moves downward to drive the fixing plate 39 to move downward. At the same time, the fixing plate 39 moves downward to drive the first trapezoidal block 310 to move downward. The first trapezoidal block 310 moves downward to contact and squeeze the first inclined block 38 to move in the direction close to the first telescopic elastic rod 37, releasing the restriction on the C-shaped plate 36. Subsequently, when the first telescopic elastic rod 37 loses the effect of the fixing plate 39 on it, the first telescopic elastic rod 37 deforms and restores its movement and pushes the first inclined block 38 to move to limit the first trapezoidal block 310. At this time, the placement table 31 completes the limitation of the purifier 1, improving the stability of the device during the transfer process, avoiding bumps or damage to the device caused by improper fixation, effectively preventing accidental movement or tilting of the device during the transfer process, which is crucial for the stability of the blood purification device, reducing the pressure and wear on the internal components of the device, and helping to extend the service life of the device. When it is necessary to separate the purifier 1 from the placement table 31, the purifier 1 is moved downward. At the same time, the first inclined block 38 presses down the sliding block 311 under the action of the first telescopic elastic rod 37 until it contacts the first trapezoidal block 310. At this time, pulling the purifier 1 upward can achieve separation. When the device needs to travel with a vehicle, the size of the device can be changed by adjusting the telescopic column 32 to adapt to the internal space of the vehicle, improving the adaptability of the device and its passability in different environments.

[0031] Please refer to Figures 1-9, on the basis of the above embodiments, in another embodiment of the present invention, a limiting device for limiting the pulley 312 when the purifier 1 is docked is provided on the circumferential surface of the sliding rod 34. The limiting device includes a sleeve plate 41 fixedly installed on the circumferential surface of the sliding rod 34. A limiting plate 42 is fixedly installed on the surface of the pulley 312. A brake plate 43 is fixedly installed on the surface of the limiting plate 42. A second telescopic elastic rod 44 is fixedly installed on the surface of the limiting plate 42. An inclined rod 45 is fixedly installed on the surface of the sleeve plate 41. A lubricating box 46 is fixedly installed at the bottom of the base 33. An oil delivery pipe 47 penetrates through the bottom of the lubricating box 46. A connecting rod 48 is fixedly installed on the surface of the inclined rod 45. A pressing plate 49 is slidably installed on the inner wall of the lubricating box 46. When the inclined rod 45 moves downward, it drives the connecting rod 48 to move, and the connecting rod 48 drives the pressing plate 49 to move. At this time, the pressing plate 49 pumps out the lubricating oil accumulated inside the lubricating box 46 through the oil delivery pipe 47 to lubricate the pulley 312. A closing plate 410 is fixedly installed on the circumferential surface of the connecting rod 48.

[0032] The free end of the second telescopic elastic rod 44 is fixedly connected to the surface of the pulley 312, the surface of the connecting rod 48 is fixedly connected to the pressing plate 49, the sleeve plate 41 slidably penetrates through the surface of the base 33, and when the sliding rod 34 moves downward, it drives the sleeve plate 41 to move. At this time, the sleeve plate 41 moves downward to drive the inclined rod 45 to move.

[0033] The material of the brake plate 43 is rubber. One end of the inclined rod 45 close to the pulley 312 is provided with an inclined surface four, and the surface of the limiting plate 42 is provided with an inclined surface five. The brake plate 43 contacts the pulley 312 under the action of the limiting plate 42 and fixes and limits the pulley 312.

[0034] An anti-tipping device for preventing the base 33 from tipping over is provided on the surface of the sleeve plate 41. The anti-tipping device includes a telescopic fixed plate 51 fixedly installed on the surface of the sleeve plate 41. A protective plate 52 is fixedly installed at the free end of the telescopic fixed plate 51. A third telescopic elastic rod 53 is slidably installed on the surface of the base 33. An inclined block two 54 is fixedly installed on the surface of the telescopic fixed plate 51. An inclined plate 55 is fixedly installed on the surface of the base 33. A fixed rod 56 slidably penetrates through the protective plate 52. A contact plate 57 is fixedly installed at the end of the fixed rod 56 far from the base 33. A pressing plate 58 is fixedly installed at the end of the fixed rod 56 close to the base 33. A fourth telescopic elastic rod 59 is fixedly installed on the surface of the pressing plate 58. A pressure plate 510 is slidably installed on the surface of the base 33. When the fixed rod 56 moves, it drives the pressing plate 58 to move, and the pressing plate 58 moves to contact and squeeze the pressure plate 510 to move downward. An anti-tipping plate 511 is fixedly installed at the end of the pressure plate 510 far from the base 33. A fifth telescopic elastic rod 512 is fixedly installed on the surface of the anti-tipping plate 511.

[0035] The free end of the telescopic elastic rod three 53 is fixedly connected to the protection plate 52. The surface of the inclined block two 54 is set as the inclined surface six. One end of the inclined plate 55 close to the inclined block two 54 is set as the inclined surface seven. A clamping groove is formed on the surface of the protection plate 52. The contact plate 57 fits with the clamping groove. When an external force contacts and pushes the contact plate 57 to move towards 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 the inclined surface eight. The free end of the telescopic elastic rod four 59 is fixedly connected to the surface of the protection 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 one end of the pressure plate 510 away from the anti-tilting plate 511 is set as the inclined surface nine.

[0036] During the operation of this embodiment: When the purifier 1 moves downward to contact and squeeze the sliding rod 34 to move downward, at the same time, the downward movement of the sliding rod 34 drives the sleeve plate 41 to move. At this time, the downward movement of the sleeve plate 41 drives the inclined rod 45 to move. The downward movement of the inclined rod 45 contacts and squeezes the limit plate 42 to move away from the pulley 312. At the same time, the movement of the limit plate 42 drives the brake plate 43 to move to release the limit on the pulley 312. At this time, the pulley 312 can rotate, realizing that the pulley 312 can rotate or not according to whether the purifier 1 is connected to the placement table 31. Releasing the limit on the pulley means that the device can move or adjust its position freely, providing higher flexibility and facilitating doctors or patients to adjust the position of the device during the treatment process to ensure that the device can easily adapt to different treatment environments. When the staff takes away the purifier 1, at this time, the limit plate 42 loses the effect of the inclined rod 45 on it. The telescopic elastic rod two 44 deforms and restores to pull the limit plate 42 to move towards the pulley 312. At this time, the brake plate 43 contacts the pulley 312 under the action of the limit plate 42 and fixes and limits the pulley 312. At this time, the pulley 312 cannot rotate, improving the stability of the device in the unconnected state and avoiding sliding or rolling due to external forces and then causing improper situations, preventing unnecessary movement of the device and ensuring the stability of the device during use. At the same time, the inclined rod 45 moves downward under the action of the sleeve plate 41. The downward movement of the inclined rod 45 drives the connecting rod 48 to move. The movement of the connecting rod 48 drives the pressing plate 49 to move. At this time, the movement of the pressing plate 49 pumps out the lubricating oil accumulated inside the lubricating box 46 through the oil delivery pipe 47 to lubricate the pulley 312, which can reduce the friction between the pulley and the contact components, thereby reducing wear and extending the service life of the device.

[0037] When the template 41 moves under the action of the sliding rod 34 to drive the telescopic fixing plate 51 to move upward, the movement of the telescopic fixing plate 51 drives the protective plate 52 to move upward to achieve the effect of protecting 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 downward movement of the telescopic fixing plate 51 drives the second inclined block 54 to move. The movement of the second inclined block 54 contacts and moves in the direction close to the sliding rod 34 under the action of the inclined plate 55. The movement of the second inclined block 54 drives the free end of the telescopic fixing plate 51 to contract, realizing that the outer protective plate 52 will be retracted during the transfer of the connection and will be opened when the purifier 1 is separated from the placement table 31. This avoids the influence of the outer components on the passability and adaptability of the equipment during the transfer process, and the retractable design of the protective plate makes the operation of the equipment more convenient. The equipment can move freely without being hindered by the presence of the protective plate, which helps to improve the flexibility of the equipment. When moving the equipment, it is easier to adjust the position or perform cleaning and maintenance operations, etc. When the base 33 not connected to the purifier 1 is subjected to an 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 pressing plate 58 to move. The movement of the pressing plate 58 contacts and presses the pressure plate 510 to move downward. At this time, the pressure plate 510 moves downward under the action of the pressing plate 58 to drive the anti-tilting plate 511 to move downward to support the base 33. When the external force is too large and the contact plate 57 has been in contact with the protective plate 52, the force will push the protective plate 52 to move in the direction close to the base 33, driving the anti-tilting plate 511 to move downward for a longer distance to provide additional protection for the equipment and effectively extend the service life of the equipment.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
