DETAILED DESCRIPTION

[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] Please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 9 As shown in

[0033] This application provides a non-contact blood purification device, including a blood purification instrument 1. The blood purification instrument 1 uses an external energy field technology to indirectly act on the blood to achieve the purpose of removing harmful substances and restoring blood health. During the purification process, the device does not directly contact the patient's blood, thus avoiding problems such as infection risk, blood loss, and equipment maintenance that may exist in traditional blood purification methods. Two chutes 2 are opened on the outside of the blood purification instrument 1, and a folding table 4 is connected to the blood purification instrument 1 through an opening and closing mechanism 3. A support bar 5 is fixedly connected to the blood purification instrument 1;

[0034] A support rod 6 is slidably connected in each of the two chutes 2. The two support rods 6 are connected through a synchronization mechanism 7. An automatically ejectable support block 8 is provided on the support rod 6 to support the folding table 4. During the rotation of the folding table 4, the folding table 4 will contact the cross bar 71 and push the cross bar 71 upward. After that, the cross bar 71 drives the vertical plate 72 and the dovetail plate 73 to move upward. When the folding table 4 rotates 90 degrees and is in a horizontal state, the through groove 12 just aligns with the placement groove 10, so that the spring 11 ejects the support block 8, and thus the support block 8 supports at the bottom of the folding table 4. When the folding table 4 is in a horizontal state, the folding table 4 will also contact the support bar 5, so that the folding table 4 is supported by the support bar 5. Furthermore, the support bar 5 and the support block 8 support at the bottom of the folding table 4, enhancing the support strength, and thus improving the stability of the folding table 4 during use.

[0035] A dovetail groove 9 is formed through the top of the support rod 6. One side of the cavity of the dovetail groove 9 is open. A placement groove 10 communicating with the dovetail groove 9 is formed inside the support rod 6. The support block 8 is slidably connected in the placement groove 10. A spring 11 is fixedly connected to the placement groove 10, and the spring 11 is fixedly connected to the support block 8.

[0036] Embodiment 2

[0037] Based on Embodiment 1, refer to Figure 1 、 Figure 4 and Figure 5 as shown.

[0038] The synchronization mechanism 7 includes a cross bar 71 disposed between two support rods 6. Both ends of the cross bar 71 are fixedly connected with vertical plates 72, and a dovetail plate 73 adapted to the dovetail groove 9 is fixedly connected to the vertical plate 72. By pulling the cross bar 71, the two support rods 6 are driven to move synchronously, so that the support rods 6 slide out from the sliding groove 2, and the limit of the support rods 6 is realized by the mutual cooperation of the convex block 15 and the baffle 16.

[0039] Through grooves 12 are formed through one side of the dovetail plate 73 and the vertical plate 72. The bottom of the groove cavity of the through groove 12 is open, and the through groove 12 is adapted to the support block 8.

[0040] A connecting rod 13 is fixedly connected to the bottom of the support block 8. A connecting groove 14 communicating with the placement groove 10 is formed in the bottom of the support rod 6, and a magnetic block for fixing the connecting rod 13 is arranged in the connecting groove 14. When restoring the folding table 4, the support block 8 is driven to move by moving the connecting rod 13, so that the support block 8 moves into the placement groove 10. After that, the spring 11 is compressed under force. When the connecting rod 13 moves to fit the groove wall of the connecting groove 14, the connecting rod 13 is fixed by the magnetic block in the connecting groove 14, so as to fix the support block 8. After the folding table 4 loses the support of the support block 8, the motor 373 is used to drive the folding table 4 to reset.

[0041] The length of the cross bar 71 is the same as the width of the folding table 4, and an anti - detachment block 17 is fixedly connected to the top of the vertical plate 72. By providing the anti - detachment block 17, the synchronization mechanism 7 can be prevented from falling off the support rod 6.

[0042] Embodiment 3

[0043] Based on Embodiment 1, refer to Figures 1 - 3 as shown.

[0044] The opening and closing mechanism 3 includes a first fixed seat 31 and a second fixed seat 32 fixedly connected in the blood purification instrument 1. Grooves 33 are formed through the first fixed seat 31 and the second fixed seat 32. A straight rod 34 is arranged between the two grooves 33. A connecting seat 35 is fixedly connected to the straight rod 34. The connecting seat 35 is fixedly connected to the folding table 4. A convex shaft 36 is fixedly connected to the connecting seat 35. The convex shaft 36 is located in the groove 33. A rotatable folding rod 37 is arranged on the first fixed seat 31. The folding rod 37 is movably connected to the straight rod 34. When the motor 373 is started, the motor 373 drives the second rod body 372 to rotate, and then drives the first rod body 371 to rotate, thereby driving the straight rod 34 to move in the straight groove 331. Thus, the straight rod 34 pushes the connecting seat 35 to drive the folding table 4 to move. At the same time, the convex shaft 36 moves inside the straight groove 331 along with the movement of the connecting seat 35. When the convex shaft 36 moves to one side of the straight groove 331, at this time, the whole folding table 4 moves out from the blood purification instrument 1, and the convex shaft 36 moves from the straight groove 331 to the arc groove 332. Thus, the connecting seat 35 rotates with the convex shaft 36 as the fulcrum, thereby driving the folding table 4 to rotate, so that the folding table 4 rotates 90 degrees.

[0045] The groove 33 is composed of a straight groove 331 and an arc groove 332 which are communicated with each other.

[0046] The folding rod 37 includes a first rod body 371 rotatably connected to the straight rod 34. A second rod body 372 is rotatably connected to the first rod body 371. An electric motor 373 is fixedly connected to the outside of the blood purification instrument 1. The electric motor 373 is a three-phase asynchronous motor, electrically connected to an external power supply and controlled by an external control program. The output end of the electric motor 373 penetrates through the blood purification instrument 1 and the first fixed seat 31 in sequence and is fixedly connected to the second rod body 372.

[0047] Embodiment 4

[0048] Combined with Embodiment 1, Embodiment 2 and Embodiment 3, see Figures 1 - 9 as shown.

[0049] After the folding table 4 is opened by using the opening and closing mechanism 3, the support bars 5 and the support blocks 8 are used to support the bottom of the folding table 4, enhancing the support strength, so that the stability of the folding table 4 can be improved during use.

[0050] The working principle of the present invention: By pulling the cross bar 71, the two support rods 6 are driven to move synchronously, so that the support rods 6 slide out from the sliding grooves 2, and the limit of the support rods 6 is realized by the mutual cooperation of the convex blocks 15 and the baffles 16.

[0051] After that, the motor 373 is started. Then, the motor 373 drives the second rod 372 to rotate, which in turn drives the first rod 371 to rotate, thereby driving the straight rod 34 to move in the straight groove 331. Thus, the straight rod 34 pushes the connecting seat 35 to drive the folding table 4 to move. At the same time, the convex shaft 36 will move inside the straight groove 331 along with the movement of the connecting seat 35. When the convex shaft 36 moves to one side of the straight groove 331, at this time, the entire folding table 4 is removed from the blood purification instrument 1, and the convex shaft 36 will move from the straight groove 331 to the arc groove 332. Thus, the connecting seat 35 will rotate with the convex shaft 36 as the fulcrum, thereby driving the folding table 4 to rotate, causing the folding table 4 to rotate 90 degrees.

[0052] During the rotation of the folding table 4, the folding table 4 will come into contact with the cross bar 71 and push the cross bar 71 upward. Then, the cross bar 71 drives the vertical plate 72 and the dovetail plate 73 to move upward. When the folding table 4 rotates 90 degrees and is in a horizontal state, the through groove 12 just aligns with the placement groove 10 in a straight line. Thus, the spring 11 pops out the support block 8, so that the support block 8 supports at the bottom of the folding table 4. When the folding table 4 is in a horizontal state, the folding table 4 will also come into contact with the support bar 5, thereby supporting the folding table 4 through the support bar 5. Furthermore, the support bar 5 and the support block 8 support at the bottom of the folding table 4, enhancing the support strength, so that the stability of the folding table 4 can be improved during use.

[0053] When restoring the folding table 4, the support block 8 is driven to move by moving the connecting rod 13, so that the support block 8 moves into the placement groove 10. Then, the spring 11 is in a compressed state under force. When the connecting rod 13 moves to fit the groove wall of the connecting groove 14, the magnetic block in the connecting groove 14 is used to fix the connecting rod 13, thereby realizing the fixation of the support block 8. After the folding table 4 loses the support of the support block 8, the motor 373 is used to drive the folding table 4 to reset.

[0054] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
