Technical Field
[0001] The utility model relates to the technical field of dialysis machines, in particular to a support structure used in dialysis machines. Background Art
[0002] Hemodialysis is the main treatment method for renal failure and uremia in clinical practice. Figure 1 As shown in the figure, during the hemodialysis treatment, the first step is the exhaust stage, with the venous end facing upwards and the arterial end facing downwards and connected to normal saline, and the blood pump is started to allow the normal saline to flow into the blood chamber of the dialyzer to remove the gas therein; then the dialyzer is turned 180 degrees with the venous end facing downwards, and the second step of pre-flushing stage begins, in which normal saline flows into the blood chamber of the blood pipeline machine dialyzer for flushing, so as to completely exhaust the air in the pipeline and the blood chamber, and humidify the dialysis membrane to facilitate full contact between the blood and the dialysate during dialysis, thereby achieving a better dialysis effect, and at the same time, it can also remove the residue in the pipeline and reduce the patient's micro-inflammatory symptoms; only then can the third step of hemodialysis treatment begin, and the patient's blood is discharged from the arterial end at the top of the dialyzer The dialysate flows in from the venous end at the bottom of the dialyzer and flows out from the dialysis waste liquid discharge end at the top of the dialyzer. The two flow in opposite directions on both sides of the dialysis membrane, and through the hollow fibers in the dialyzer, the metabolic waste and excess water in the blood are removed, while the therapeutic effect of replenishing the required substances in the body is achieved. After the dialysis treatment is completed, the fourth step of waste liquid removal is required. At this time, the dialysis waste liquid in the dialyzer needs to be discharged to reduce the amount of medical waste liquid. At this time, the dialyzer needs to be flipped 180° so that the dialysis waste liquid discharge end faces downward (that is, the venous end of the dialyzer faces upward and the arterial end faces downward), and the dialysis waste liquid in the dialyzer is discharged cleanly using the negative pressure device in the dialyzer. It can be seen that during the entire dialysis treatment process, the dialyzer needs to be flipped 180° twice.
[0003] In the prior art, the dialyzer is fixed to the bracket beside the dialysis machine by a clip, but the clip in the prior art cannot be directly flipped 180°. Medical staff need to take the dialyzer off the clip, flip it over, and then put it back into the clip every time. This requires the medical staff to hold the dialyzer with one hand and open the clip with the other hand. Not only do both hands have to be occupied, but it is also inconvenient to exert force after the hand and arm holding the dialyzer are flipped 180°, which may cause the dialyzer to slip out of the hand accidentally. In addition, the dialyzer is also connected to pipelines, and the operator has no extra hands to tidy up the pipelines during the rotation process. In this way, these pipelines are easily entangled during the flipping of the dialyzer, which may easily cause the pipelines to be squeezed or bent, thereby easily affecting the smooth flow of the fluid in the pipeline and affecting the normal operation of the dialyzer.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention.
[0024] like Figure 2 , Figure 3 As shown, the utility model provides a support structure applied to a dialysis machine, including a support body 1, a fixing clip 2, and in order to achieve the purpose of the utility model, a rotating mechanism 3 is further included, and the fixing clip 2 is rotatably connected to the support body 1 through the rotating mechanism 3. In this way, medical staff only need one hand to turn the dialyzer 180°, which greatly improves the convenience of operation; and when the medical staff turns the dialyzer with one hand, the other hand can comb the pipelines connected to the dialyzer at the same time, without having to spend time to organize the pipelines separately, which helps to save operation time, improve the work efficiency of medical staff, and reduce the waiting time of patients.
[0025] like Figure 2 , Figure 3 As shown, the rotating mechanism 3 includes a mounting base 31, a nut 32, a rotating ball 33, and a connecting rod 34. The rotating ball 33 is rotatably embedded in the mounting base 31, the nut 32 is screwed onto the mounting base 31, one end of the connecting rod 34 is connected to the rotating ball 33, and the other end of the connecting rod 34 is connected to the bracket body 1. Figure 4 As shown, the mounting base 31 is arranged on the back of the fixing clamp 2, and a spherical groove 311 is provided on the mounting base 31, and the rotating ball 33 is embedded in the spherical groove 311, so that the rotating ball 33 can rotate freely in the spherical groove. Preferably, the rotating ball 33 and the connecting rod 34 are an integrated structure, so that the mechanical strength of the rotating ball 33 and the connecting rod 34 is greater, and it is more stable to use. Figure 3 As shown, a plurality of notches 312 are provided at the notch of the spherical groove, and these notches form elastic contraction openings at the notch. When the nut 32 is screwed onto the mounting base 31, the mounting base 31 always keeps close contact with the rotating ball 33 during the rotation process along the rotating ball 33 to prevent loosening and falling. And by using the rotating ball 33 as the rotation axis, the fixing clamp 2 can rotate 360° with the rotating ball 33 as the axis, so that the dialyzer can not only be turned 180° in the vertical direction, but also be rotated up and down within a certain range in the horizontal direction. In this way, in the process of connecting the dialyzer to the pipeline, the medical staff does not need to bend down, but only needs to rotate the dialyzer to a suitable angle to connect the pipeline to the dialyzer, thereby greatly reducing the workload of the medical staff.
[0026] like Figure 2 , Figure 3As shown, the support structure of the utility model also includes a telescopic component 4 and a connecting component 5, wherein the telescopic component 4 is installed on the support body 1 through the connecting component 5, and the connecting rod 34 is connected to the support body 1 through the telescopic component 4 and the connecting component 5. In this way, when the dialyzer is fixed on the fixing clamp, a space for the dialyzer to rotate will be reserved between the dialyzer and the support body 1, preventing the dialyzer from hitting the support body 1 during rotation. In addition, medical staff can pull the dialyzer forward through the telescopic component 4 to keep it away from the support body 1, which can more conveniently rotate the dialyzer on the one hand, and more effectively prevent the dialyzer from hitting the support body 1 and the dialysis machine host on the other hand.
[0027] like Figure 5 , Figure 6 The telescopic assembly 4 includes a sleeve 41, a telescopic rod 42, and a spring 43. The telescopic rod 42 is placed in the sleeve 41, and the front end of the telescopic rod 42 extends out of the sleeve 41 and is connected to the connecting rod 34. The spring 43 is sleeved on the telescopic rod 42, and the spring 43 elastically presses the telescopic rod 42 backward, and the side wall of the sleeve 41 is connected to the connecting assembly 5. Preferably, the telescopic rod 42 and the connecting rod 34 are an integrated structure, so that the mechanical strength is greater and it is more stable to use; when the dialyzer needs to be turned over, the medical staff pulls the telescopic rod 42 forward, and the telescopic rod 42 slides forward along the sleeve 41. After the medical staff turns the dialyzer over, they let go, and the spring 43 can drive the telescopic rod 42 to return to the sleeve 41, and then drive the dialyzer to return to the front end of the sleeve 41.
[0028] like Figure 5 , Figure 6 As shown, the front end of the sleeve 41 is provided with a blocking convex ring 411, the front end of the telescopic rod 42 passes through the inner hole of the blocking convex ring 411, and the rear end of the telescopic rod 42 is provided with a limiting convex ring 421. The spring 43 is sleeved on the telescopic rod 42 between the blocking convex ring 411 and the limiting convex ring 421, and the two ends of the spring 43 are elastically pressed against the blocking convex ring 411 and the limiting convex ring 421. In this way, after the telescopic rod 42 is pulled out of the sleeve 41, the spring 43 is compressed between the blocking convex ring 411 and the limiting convex ring 421, and after the medical staff releases their hands, the spring 43 rebounds to reset the telescopic rod 42 to the sleeve 41.
[0029] like Figure 5 , Figure 6 As shown, an internal thread 412 is provided on the rear end of the sleeve 41, and a limit cover 44 is screwed on the internal thread 412. In this way, the limit cover 44 can limit the telescopic rod 42 and the spring 43 in the sleeve 41 to ensure the stability of the telescopic rod assembly 4.
[0030] like Figure 7As shown, the connection assembly 5 includes a connection seat 51 and a first hand-tightening bolt 54. One end of the connection seat 51 is connected to the sleeve 41. A vertical through hole 52 is provided on the connection seat 51. A shrinkage notch 53 is provided on the hole wall of the vertical through hole 52, which penetrates to the other end of the connection seat 51. The threaded end of the first hand-tightening bolt 54 penetrates the shrinkage notch 53 and is screwed to the connection seat 51. The vertical through hole 52 can be vertically slidably sleeved on the bracket body 1. In this way, medical staff can adjust the position of the connection assembly 5 on the bracket body 1 at any time through the first hand-tightening bolt 54, thereby facilitating various operations of medical staff during the dialysis process.
[0031] The bracket body 1 also includes a hook assembly 6. The top of the bracket body 1 is provided with a threaded connector. The hook assembly 6 is composed of a crossbar and a hook arranged on the crossbar. The middle of the crossbar is provided with a threaded hole, and the threaded hole is screwed to the threaded connector. In this way, during transportation, the hook assembly 6 can be separated from the bracket body 1 into two regular vertical rods, thereby reducing the packaging volume and facilitating packaging and transportation.
[0032] The hook is respectively provided with a fixing screw hole and a sleeve hole, and the inner end of the fixing screw hole is passed through the sleeve hole, and the sleeve hole is slidably sleeved on the cross bar, and a second hand-tightened bolt is screwed on the fixing screw hole, and the inner end of the second hand-tightened bolt is pressed against the cross bar. In this way, the hook can be removed from the cross bar, which is further convenient for packaging and transportation. During use, the position of the hook can also be adjusted at any time to avoid squeezing together when multiple medicine bags are hung on the bracket. The position of the fixing screw hole is preferably set on the side of the sleeve hole, so that when the hook is installed on the cross bar, the fixing screw hole and the second hand-tightened bolt can be placed in the direction facing the medical staff, so as to facilitate the medical staff to adjust the position of the hook.
