When in use, the two extension storage boxes 5 can be pulled out to the outermost side between the upper baffle 4 and pushed down. During this process, the rectangular protruding block at the top of the front and rear sides of the extension storage box 5 will slide in the L-shaped slot on the upper baffle 4, thereby guiding it. Finally, the rectangular protruding block on the extension storage box 5 can also limit it.

[0044] In this embodiment, as shown in Figure 1 , Figure 3 and Figure 5 , the folding baffle 8 can rotate in the hollow slot inside the waste collection bracket 7, and after the folding baffle 8 rotates inward, it will be in close contact with the inner wall of the side of the waste collection bracket 7. When the waste collection bracket 7 is pulled out to the outermost side and the folding baffle 8 is rotated outward, one end of the folding baffle 8 will be in close contact with the outer wall of the treatment vehicle body 1. After the waste collection bracket 7 is pulled out to the outermost side, the folding baffle 8 can be rotated to the most front side. At this time, the folding baffle 8 will block the opening on the front side of the waste collection bracket 7. Therefore, medical waste can be placed in the hollow cavity inside the waste collection bracket 7. When the waste collection bracket 7 needs to be folded, the folding baffle 8 can be rotated back, and then the waste collection bracket 7 can be pushed back towards the treatment vehicle body 1. Finally, the folding baffle 8 will also be in close contact with the outer wall of the side of the treatment vehicle body 1.

When the waste collection bracket 7 needs to be folded, the rectangular plate part of the bottom and rear side of the waste collection bracket 7 can also be slid into the first guide slot 10.

[0047] In this embodiment, as shown in Figure 9 and Figure 10When the waste collecting bracket 7 is pulled out, the bottom edge of one side of the positioning block 13 will contact the inclined surface of the top of the positioning block 13, and then the positioning block 13 can be pushed to slide downward on the inside of the fixing plate 12, and finally the bottom surface of the positioning block 13 will be in close contact with the ground, thereby automatically locking the position of the treatment vehicle body 1 to prevent the treatment vehicle body 1 from being displaced during the treatment process. After the waste collecting bracket 7 is retracted, the positioning block 13 will slide up to the top again, and at this time the bottom surface of the positioning block 13 will be separated from the ground, and then the treatment vehicle body 1 can be pushed to move.

[0048] In this embodiment, Figure 9 and Figure 10 As shown, a magnet is provided inside the stop blocks 14 on the front and rear sides of the positioning block 13, the fixed plate 12 is an iron plate, and when the positioning block 13 slides to the top, the stop block 14 will be in close contact with the bottom surface of the fixed plate 12, and after the waste collection bracket 7 is retracted, there will be no obstruction on the top of the positioning block 13, so the magnet inside the stop block 14 will be attracted to the fixed plate 12 and drive the positioning block 13 to slide to the top, at which time the bottom surface of the positioning block 13 will be separated from the ground, thereby being able to push the treatment vehicle body 1 to move.

[0049] Example 2, based on Example 1, Figures 1-10 As shown, two round holes are provided on the rectangular rod at the top of the front side of the waste collecting bracket 7, and two round holes are also provided on the top of the folding baffle 8. When the folding baffle 8 is rotated to the frontmost side, the round rod at the bottom of the positioning pin 9 can be inserted into the round holes on the rectangular rod at the top of the front side of the waste collecting bracket 7 and the folding baffle 8. After the waste collecting bracket 7 is pulled to the outermost side, the folding baffle 8 can be rotated to the frontmost side. At this time, the round holes on the rectangular rod at the top of the front side of the waste collecting bracket 7 will be aligned with the round holes on the top of the folding baffle 8, and then the positioning pin 9 can be inserted into the round holes on the rectangular rod at the top of the front side of the waste collecting bracket 7 and the folding baffle 8, so that the position of the folding baffle 8 can be fixed.

[0050] The working principle of this embodiment is as follows: when in use, the tools and dialysate used for peritoneal dialysis can be stored in the cavity inside the storage drawer 3 and in the extended storage slot 6. When it needs to be moved, the treatment vehicle body 1 can be moved by supporting the support wheels 2. When the patient needs to undergo membrane dialysis treatment, the waste collection bracket 7 and the positioning pin 9 on the front side of the extended storage box 5 can be pulled out and disassembled first. At this time, the two waste collection brackets 7 can be pulled out to both sides respectively. During this process, the rectangular protrusions at the top position of the front and rear sides of the waste collection bracket 7 will slide in the open grooves on the front and rear outer walls of the treatment vehicle body 1, thereby ensuring the stability of the waste collection bracket 7 when sliding, and also playing a limiting role for the waste collection bracket 7. After the waste collection bracket 7 is pulled to the outermost side, The foldable baffle 8 can be rotated to the front most side, at this time the round hole on the rectangular rod at the front top of the waste collecting bracket 7 will be aligned with the round hole at the top of the foldable baffle 8, and then the positioning pin 9 can be inserted into the round hole on the rectangular rod at the front top of the waste collecting bracket 7 and the foldable baffle 8, so that the position of the foldable baffle 8 can be fixed. At this time, the foldable baffle 8 will block the opening on the front side of the waste collecting bracket 7, so that medical waste can be placed through the cavity inside the waste collecting bracket 7, and when the waste collecting bracket 7 is pulled outward, the bottom edge position of one side will contact the inclined surface of the top of the positioning block 13, and then the positioning block 13 can be pushed to slide downward on the inside of the fixed plate 12, and finally the bottom surface of the positioning block 13 will be in close contact with the ground, so it can be automatically The position of the treatment cart body 1 is locked automatically to prevent the treatment cart body 1 from being displaced during the treatment process, and then the two extended storage boxes 5 are pulled outward to the outermost side between the upper baffle 4 and pushed downward. During this process, the rectangular protrusions at the top position of the front and rear sides of the extended storage box 5 will slide in the L-shaped groove on the upper baffle 4, thereby guiding it. Finally, the rectangular protrusions on the extended storage box 5 can also limit it, and then the extended storage box 5 will be tightly attached to the left and right outer walls of the treatment cart body 1. At the same time, the top surface of the extended storage box 5 can form an operating table together with the top surface of the treatment cart body 1, which is convenient for placing medical equipment, medical orders and other items. Then the patient can be given peritoneal dialysis treatment. After the treatment is completed, the treatment cart needs to be put When folding, first take out the medical waste in the waste collection bracket 7, and rotate the folding baffle 8 backward again, and then push the waste collection bracket 7 back toward the treatment cart body 1. During this process, the waste collection bracket 7 will slide into the first guide groove 10 and the second guide groove 11 for storage. Finally, the folding baffle 8 will also be in close contact with the side outer wall of the treatment cart body 1, and after the waste collection bracket 7 is retracted, there will be no obstruction on the top of the positioning block 13. Therefore, the magnet inside the baffle 14 will be attracted to the fixed plate 12 and drive the positioning block 13 to slide up to the top. At this time, the bottom surface of the positioning block 13 will be separated from the ground, thereby pushing the treatment cart body 1 to move, and then push the expansion storage box 5 upward and push it inward again between the two upper baffles 4.Moreover, when the expansion storage box 5 and the waste collection bracket 7 are folded up, they will be close to each other. At this time, the positioning pin 9 can be installed, so that the two expansion storage boxes 5 or the two waste collection brackets 7 can be firmly locked together, and the expansion storage box 5 and the waste collection bracket 7 can be fixed in the folded state, reducing the space occupied when stored.
