The patient's arm is placed flat on the arm support plate and the arm support plate is pressed down by the arm, so that a second rotation limiting unit limits the arm support plate from rotating along the axial direction of the arm support, and a first rotation limiting unit limits the rotating frame from rotating along its axial direction, thereby locking the adjusted orientation, thereby meeting the requirements for further convenient operation and use when switching between different supine or sitting hemodialysis positions, or changing different positions for hemodialysis.

Description

Technical Field

[0001] The present invention relates to the technical field of hemodialysis machines, and in particular to a portable and movable hemodialysis machine. Background Art

[0002] The hemodialysis machine uses the principles of dialysis and hydrostatic pressure. It consists of a part where the patient's blood passes, a part where the dialysate passes, and a semi-permeable membrane set between the two. Through the micropores of the membrane, waste and excess water flow from the blood into the dialysate, while the blood cells and proteins needed by our body are relatively large and cannot pass through the holes and remain as they are. Generally, patients need to lie flat or sit when undergoing hemodialysis to expose the blood vessels in their arms. Existing hemodialysis machines, such as a hemodialysis machine disclosed in Chinese patent document CN107812263A, include a hemodialysis machine, a control panel, a dialysis box, an alarm and an injection stand. The dialyzer, the dialysis box and other equipment are mounted on a pallet, and the universal wheels at the bottom of the pallet slide freely to achieve the function of a mobile device. However, considering that patients usually need to use the dialysis machine for hemodialysis treatment several times a week, and each use time is about 4-6 hours, the frequency and time are both high. Therefore, when the patient needs to switch to different supine or sitting dialysis, or change different positions for dialysis, for example, when using a sitting dialysis away from the bed, it is often necessary to lift and fix the arm, and the dialysis machine needs to be better fixed. When changing to a supine position dialysis on the bed, the dialysis machine needs to be conveniently moved to the corresponding position and the arm is retracted. Fixing, therefore, the existing conventional hemodialysis machine is not enough to meet the requirements of further convenient operation and use when switching to different supine or sitting dialysis, or changing different positions for dialysis. Summary of the invention

[0003] In view of this, the purpose of the present invention is to propose a portable and movable hemodialysis machine to solve the problem that the existing conventional hemodialysis machines are not sufficient to meet the requirements of further convenient operation and use when switching between different supine or sitting positions for dialysis, or changing different positions for dialysis.

When using a sitting dialysis away from the bed, the telescopic part is pulled outward and the rotating frame is rotated axially so that the arm support is facing upward. At this time, the height adjustment unit pushes the base frame to slide downward until the suction cup moves to the bottom of the base. At this time, the suction cup is pressed down and adsorbed on a certain height position away from the bed and relatively open such as a desktop. The patient's arm is placed flat on the arm support to achieve stable sitting dialysis. The arm support can be freely rotated at different angles along the axis of the arm support, and the rotating frame can be freely rotated at different angles along its axis to adjust the corresponding position required to hold the patient's arm.

[0033] like Figure 1 , Figure 2As shown, a portable and movable hemodialysis machine includes a dialysis machine body 1 and a base 2. The dialysis machine body 1 is supported and mounted on the top of the base 2. A base frame 3 is arranged around the inner side wall of the base 2. The base frame 3 is slidably connected to the base 2. A suction cup 4 is connected to the bottom end of the base frame 3. The rotating frame 5 is designed to be a transverse telescopic structure, including a fixed portion 51 that transversely penetrates the top of the base 2 and a telescopic portion 52 that penetrates one end of the fixed portion 51. The telescopic portion 52 is located on the outside of the base 2. The fixed portion 51 is rotatably connected to the base 2, and a first rotation limiting unit is connected between the fixed portion 51 and the base 2. An arm bracket 6 is connected to the end of the telescopic portion 52 away from the base 2. The arm bracket 6 is away from the telescopic portion 52. An arm support plate 7 is movably connected to one end of the arm support plate 7, which is rotatably connected to the arm bracket 6 and is connected to the arm bracket 6 with a second rotation limiting unit. A height adjusting unit 8 is provided on the fixing portion 51. By axially rotating the rotating frame 5, when the arm support plate 7 faces downward, the base frame 3 slides upward until the suction cup 4 moves into the base 2. By pulling out the telescopic portion 52 and axially rotating the rotating frame 5, when the arm support plate 7 faces upward, the height adjusting unit 8 pushes the base frame 3 to slide downward until the suction cup 4 moves to below the bottom end of the base 2. By pressing down the arm support plate 7, the second rotation limiting unit limits the axial rotation of the arm support plate 7 along the arm bracket 6, and the first rotation limiting unit limits the axial rotation of the rotating frame 5 along its axial direction.

[0034] The present invention is based on the existing hemodialysis instrument structure, including a dialyzer body 1, and in particular, for the existing portable hemodialysis instrument, further including a base 2. The dialyzer body 1 is supported and mounted on the top of the base 2, and a base frame 3 is arranged around the inner side wall of the base 2. The base frame 3 is slidably connected to the base 2. Specifically, the base frame 3 can be designed to be a hollow rectangular frame structure, and sliders are fixed on both sides of the outer side of the base frame 3, and the base frame 3 is connected to the base 2 by sliding up and down through the sliders. The range of up and down movement of the base frame 3 is not large, and the space occupied by the base 2 is not large, which does not affect the portable use of the portable hemodialysis instrument. The bottom end of the base frame 3 is connected to a suction cup 4, and the rotating frame 5 is designed to be a transverse telescopic structure, including a fixed part 51 that passes through the top of the base 2 transversely and a telescopic part 52 that is penetrated at one end of the fixed part 51. Specifically, the fixed portion 51 and the telescopic portion 52 can be designed to be a telescopic column structure that is connected to each other. The telescopic portion 52 is located on the outer side of the base 2. The fixed portion 51 is rotatably connected to the base 2, and a first rotation limiting unit is connected between the fixed portion 51 and the base 2. An arm bracket 6 is connected to the end of the telescopic portion 52 away from the base 2. An arm bracket 6 is movably connected to the end of the arm bracket 6 away from the telescopic portion 52. The top of the arm bracket 7 is designed in a concave shape for fixing and supporting the patient's arm. The end of the telescopic portion 52 away from the fixed portion 51 can be designed to be a plate-like structure for better supporting the arm bracket 6. The arm bracket 7 is rotatably connected to the arm bracket 6, and a second rotation limiting unit is connected between the arm bracket 6. A height adjustment unit 8 is provided on the fixed portion 51. When dialysis is performed in a supine position on a bed, such as Figure 2As shown, by sliding the telescopic portion 52 inward and folding it, and rotating the rotating frame 5 axially so that the arm support plate 7 faces downward, the bottom frame 3 slides upward until the suction cup 4 moves into the base 2, and the dialysis machine body 1 is placed on a cabinet or table next to the bed, so that the bottom end surface of the base 2 directly contacts the table top. Since the patient lies flat on the bed with his arms flat on the bed, and the dialysis equipment is located next to the bed against the wall, there will be no significant displacement. The bottom end surface of the base 2 directly contacts the table top, which is stable enough for use. When a sitting position away from the bed is required for dialysis, the dialysis machine body 1 can be easily moved. At this time, the equipment is located at a certain height away from the bed, that is, relatively open, such as Figure 1 As shown, by pulling out the telescopic portion 52 and axially rotating the rotating frame 5 so that the arm support plate 7 faces upward, the height adjustment unit 8 pushes the bottom frame 3 to slide downward until the suction cup 4 moves to the bottom of the base 2. At this time, the suction cup 4 is pressed down and adsorbed on a certain height position away from the bed and relatively open, such as a table top, and the suction cup 4 is used to firmly adsorb the table top. The patient's arm is placed flat on the arm support plate 7 to achieve stable sitting dialysis use. In addition, because the patient's arm is placed flat on the arm support plate 7, the arm presses down the arm support plate 7 so that the second rotation limit unit The element limits the arm support plate 7 to rotate along the axis of the arm support 6, and the first rotation limit unit limits the rotation of the rotating frame 5 along its axis, so that by lifting the arm, the arm support plate 7 can freely rotate at different angles along the axis of the arm support 6, and the rotating frame 5 can freely rotate at different angles along its axis to adjust the corresponding position required for supporting the patient's arm. After the adjustment, the arm is naturally lowered, and the arm support plate 7 is pressed down to lock the adjusted position, thereby meeting the requirements of further convenient operation and use when switching between different supine or sitting dialysis positions, or changing different dialysis positions.

[0035] In an embodiment of the present invention, Figure 1 , Figure 2 As shown, the height adjustment unit 8 is a rotating wheel, and the fixing part 51 is arranged and fixed in the eccentric position of the rotating wheel. The rotating wheel is similar to the existing cam structure. When the arm support plate 7 is facing upward, the long axis end of the rotating wheel abuts against the top of the base frame 3, pushing the base frame 3 to slide downward until the suction cup 4 moves to below the bottom end of the base 2, so that the suction cup 4 can stably adsorb the desktop downward. At this time, the rotating frame 5 is rotated to adjust the position of the arm support plate 7, and the stable adsorption of the suction cup 4 will not be affected. A plurality of rotating wheels can be arranged at intervals, which is conducive to stably pushing the base frame 3. More preferably, a concave arc groove can be provided at the top of the base frame 3, and the rotating wheel pushes along the arc groove, which is conducive to more efficient pushing the base frame 3 up and down. When the arm support plate 7 is folded downward, the short axis end of the rotating wheel abuts against the top of the base frame 3.

[0036] Preferably, the suction cup 4 can adopt an existing conventional vacuum suction cup component, which is connected to the base 2 by sliding sliders on both sides of the base frame 3 up and down, and conventional elastic components such as return springs are also connected between the sliders and the base 2. When the arm support plate 7 is folded downward, the suction cup 4 is manually removed or the suction cup 4 is controlled to eliminate the vacuum, and the base frame 3 is driven to move upward by the return spring until the short axis end of the rotating wheel abuts against the top of the base frame 3.

[0037] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a threaded structure is provided on the outer end face of the arm bracket 6, and a bolt member 9 is threadedly connected. A ring sleeve 10 is sleeved on the outer side of the arm bracket 6 and located above the bolt member 9. An elastic member 11 is connected between the ring sleeve 10 and the arm support plate 7. By rotating the bolt member 9, the bolt member 9 moves up and down along the outer side of the arm bracket 6, driving the ring sleeve 10 to move up and down, thereby adjusting the height of the arm support plate 7.

[0038] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig. 9 As shown, a swivel 101 is rotatably connected to the top surface of the ring kit 10, and the swivel 101 can freely rotate axially relative to the ring kit 10. The elastic member 11 can adopt existing conventional elastic members such as springs. The bottom end of the elastic member 11 is fixedly connected to the swivel 101, and the top end of the elastic member 11 is fixedly connected to the bottom end of the arm support plate 7.

[0039] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the bottom end of the arm support plate 7 is connected with a plug post 12, the elastic member 11 can be designed as a spring structure surrounding the outside of the plug post 12, the bottom end of the plug post 12 is inserted into the arm bracket 6, and the second rotation limit unit includes a vertical limit post 13 vertically inserted into the arm bracket 6, the head end of the vertical limit post 13 is connected with an oblique limit block 14, the top end of the oblique limit block 14 is designed to be an inclined end face, and a plurality of convex strips 121 parallel to the axial direction of the plug post 12 are arranged at intervals on the outside of the plug post 12, as shown in FIG. Figure 8As shown, the bottom end of the convex strip 121 is designed to be in the shape of an arrow, and the tip of the arrow is in an arc-shaped transition, so that an opening shape facing downward is formed at the bottom end of the convex strip 121, wherein the vertical limit column 13 is designed to be a telescopic structure, and the upper part of the vertical limit column 13 is connected to the horizontal limit strip 15, and the side end of the arm bracket 6 is parallel to the axial direction thereof. A vertical groove 61 is opened, such as Figure 7 As shown, the vertical groove 61 does not affect the threaded connection between the arm bracket 6 and the bolt member 9. One end of the horizontal limit strip 15 passes through the arm bracket 6 along the vertical groove 61 and is inserted into the ring kit 10, that is, the ring kit 10 is provided with a horizontal groove 102 for the horizontal insertion of the horizontal limit strip 15. When the height of the ring kit 10 and the arm support plate 7 is adjusted by the bolt member 9, the horizontal limit strip 15 moves up and down synchronously with the horizontal groove 102, that is, the height distance between the upper part of the vertical limit column 13 and the oblique limit block 14 relative to the arm support plate 7 and the insertion column 12 does not change. When the patient's arm is placed on the arm support plate 7 and the arm support plate 7 is pressed down, the arm support plate 7 and the insertion column 12 are 12 moves downward to compress the elastic member 11, and the column 12 pushes downward against the inclined end surface of the oblique limit block 14 to make the oblique limit block 14 move laterally, wherein a space is naturally reserved in the arm bracket 6 for the vertical limit column 13 to move laterally for a short distance, and the length design of the horizontal groove 102 also reserves a space for the horizontal limit strip 15 to move laterally for a short distance, and the oblique limit block 14 slides along the bottom opening of the convex strip 121 into the interval position between adjacent convex strips 121, and laterally abuts against the side of the column 12, because the arm bracket 6 and the vertical groove 61 limit the rotation of the horizontal limit strip 15 and the vertical limit column 13, the column 12 is limited by the oblique limit block 14 to rotate along its axial direction.

[0040] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the first rotation limiting unit includes a transverse limiting column 16 which passes through the rotating frame 5, and an end portion 161 is connected to one end of the transverse limiting column 16 close to the fixed portion 51, and a long groove 17 parallel to the axial direction of the fixed portion 51 is opened on one end of the fixed portion 51, and a movable limiting ring 18 is sleeved on the outer side of the fixed portion 51 near the long groove 17, and a fixed limiting ring 19 is fixed on the inner side surface of the base 2, and a plurality of limiting holes 191 are arranged at intervals in the circumferential direction on the end surface of the fixed limiting ring 19 facing the movable limiting ring 18, and a plurality of limiting pins 181 are arranged at intervals in the circumferential direction on the movable limiting ring 18, and an L-shaped limiting strip 20 is passed through the long groove 17, as shown in FIG. Figure 4 , Figure 6As shown, the horizontal rod portion of the L-shaped limiting strip 20 is fixedly connected to the movable limiting ring 18, and the vertical rod portion of the L-shaped limiting strip 20 penetrates into the fixed portion 51 along the long groove 17. The long groove 17 and the L-shaped limiting strip 20 are arranged in a plurality of intervals along the circumferential direction, such as Figure 4 , Figure 6 , Fig.10 As shown, the fixed limiting ring 19 is connected with an elastic part 192, and the elastic part 192 can adopt an existing conventional spring or other elastic component. One end of the elastic part 192 is fixed to the fixed limiting ring 19, and the other end is used to push the movable limiting ring 18;

[0041] One end of the horizontal limiting column 16 away from the fixing portion 51 is connected to the bottom end of the vertical limiting column 13. Figure 3 , Figure 4 As shown, by pulling out the telescopic portion 52, the end portion 161 is moved laterally close to the vertical rod portion of the L-shaped limit strip 20. When the arm support plate 7 is pressed down, the oblique limit block 14 moves laterally, driving the end portion 161 to move against the vertical rod portion of the L-shaped limit strip 20, as shown in FIG. Figure 5 , Figure 6 As shown, the limit pin 181 is inserted into the limit hole 191. The limit pin 181 can be designed to be an axially elastic telescopic structure. When the limit pin 181 is inserted on the fixed limit ring 19, the limit pin 181 elastically contracts until the limit pin 181 turns to the limit hole 191, then the limit pin 181 pops out and is limitedly inserted into the limit hole 191 to limit the rotation of the rotating frame 5 along its axial direction.

[0042] In an embodiment of the present invention, Figures 1 to 10 As shown, the horizontal rod portion of the L-shaped limit strip 20 is designed to be an adjustable telescopic structure. Specifically, the existing conventional telescopic rod structure can be adopted, and a locking bolt for locking the telescopic length of the movable rod is provided at the side end of the telescopic rod, which is used to fine-tune the position of the movable limit ring 18 and the L-shaped limit strip 20 to ensure that when the oblique limit block 14 moves laterally, the vertical rod portion of the L-shaped limit strip 20 is pushed to move through the end portion 161.

[0043] In an embodiment of the present invention, Figures 1 to 10 As shown, a magnetic adsorption layer is provided on the end surface of the end portion 161 facing the horizontal limit column 16, which is used to fit and adsorb the vertical rod portion of the L-shaped limit strip 20. Therefore, when the telescopic portion 52 is pulled outward and the end portion 161 is close to the vertical rod portion of the L-shaped limit strip 20, the magnetic adsorption layer is used to naturally adsorb the vertical rod portion of the L-shaped limit strip 20.

[0044] If the first rotation limiting unit is not needed to limit the rotation of the rotating frame 5, the telescopic portion 52 only needs to be pulled outward for a short distance. At this time, the end portion 161 is not close to the vertical rod portion of the L-shaped limiting strip 20, and naturally will not push the L-shaped limiting strip 20 to move.

[0045] In an embodiment of the present invention, Figure 1 , Figure 2 As shown, a buckle 21 is provided on the outer wall of the base 2. When the telescopic portion 52 is folded inward and the arm support plate 7 is rotated downward, the arm bracket 6 is clamped by the buckle 21, thereby accommodating and fixing the arm bracket 6.

[0046] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
