Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and more specifically to a hemodialysis nursing catheter positioning device. Background Art
[0002] A care catheter is a tubular device used to deliver fluids or drugs, collect blood samples, or monitor physiological parameters. In dialysis treatment, the care catheter is used to drain the patient's blood into the dialysis machine for filtration and cleaning, and then return the processed blood to the patient. The care catheter can also be used for other medical operations such as infusing drugs, infusions, or collecting blood samples. If the patient needs to infuse multiple different fluids at the same time, such as nutrient solution, plasma, infusion, etc., each fluid requires a separate infusion channel.
[0003] The Chinese patent authorization announcement number: CN217311341U provides a hemodialysis nursing catheter fixing device. The solution compresses two groups of clamping springs by pulling a pull rod, so that the clamping plate automatically clamps the catheter in the catheter groove. By arranging multiple catheter grooves on the mounting seat, multiple groups of catheters can be conveniently classified and stored. By controlling the vertical movement of the support column in the support sleeve, the height of the mounting seat is adjusted. By pulling the positioning handle, the boss on the positioning handle is controlled to squeeze the two sides of the elastic sheet, thereby controlling the deformation of the elastic sheet, and then the elastic sheet and the friction plate are respectively clamped to the support sleeve and the support column, so that the height of the mounting seat after adjustment can be fixed. The height can be controlled according to the length of the catheter, and at the same time, medical staff can more conveniently replace the catheter on the mounting seat.
[0004] In the process of using multiple catheters for treatment, medical staff sometimes need to first connect the two ends of the catheter to the machine and the patient respectively, and then arrange and fix the multiple catheters. However, the catheter in this solution must first pass one end through the catheter groove before connecting, which causes inconvenience in use and reduces work efficiency. Therefore, a hemodialysis care catheter positioning device is proposed to address the above problems. Utility Model Content

[0032] Example:
[0033] See also Figure 1-2A hemodialysis care catheter positioning device includes a bracket 1 and a positioning assembly 6, wherein the upper end of the bracket 1 is fixedly connected to a base 2, the upper end of the base 2 is fixedly connected to a plurality of equally spaced limit blocks 3, and both ends of the base 2 are equipped with a plurality of equally spaced positioning blocks 5, one end of the limit block 3 is equipped with a first rubber pad 4, the positioning assembly 6 includes a movable rod 601, the movable rod 601 is slidably connected to the positioning block 5, and a plurality of movable blocks 604 are arranged on the upper side of the movable rod 601, a pair of sliders 606 are fixedly connected to the bottom ends of the plurality of movable blocks 604, and a second rubber pad 605 matching the first rubber pad 4 is installed on one end of the movable block 604 close to the limit block 3.
[0034] A nursing catheter is a tubular device used to transport liquids or drugs, collect blood samples or monitor physiological parameters. In the process of using multiple catheters for treatment, medical staff sometimes need to first connect the two ends of the catheter to the machine and the patient respectively, and then arrange and fix the multiple catheters. In this solution, after the medical staff have installed the multiple catheters, they can move the bracket 1 to a suitable position, and then insert any part of the multiple catheter tubes between the adjacent first rubber pads 4 and second rubber pads 605. Since the first rubber pad 4 and the second rubber pad 605 are made of flexible materials, the catheter can be squeezed between them to achieve preliminary fixation without causing wear to the outer surface of the catheter. Then the medical staff can continue to further fix all the catheters through the positioning component 6. In this way, the medical staff can fix the catheter after the catheter is installed, which effectively improves work efficiency.
[0035] See also Figure 2-3 The outer end of the movable rod 601 is fixedly connected with a plurality of abutment blocks 602, and the outer end of the movable rod 601 is sleeved with a plurality of springs 603, one end of the spring 603 is fixedly connected with the abutment block 602, the slider 606 is slidably connected with the movable rod 601, the end of the spring 603 away from the abutment block 602 is fixedly connected with the slider 606, the top of the movable block 604 is fixedly connected with a shift block 608, one end of the movable rod 601 is rotatably connected with a screw 607, one end of the screw 607 extends to the inner side of the movable rod 601 and is threadedly connected with the base 2.
[0036] In this solution, after the medical staff squeezes the multiple catheters between the multiple groups of first rubber pads 4 and the second rubber pads 605 respectively, they can rotate the screw 607 to move the screw 607 toward the inner end of the bracket 1, and then drive the movable rod 601 to move through the screw 607, and the movable rod 601 slides on the multiple positioning blocks 5, thereby driving the multiple abutment blocks 602 to move, and the multiple abutment blocks 602 push the spring 603 and the slider 606 to move, and then push the movable block 604 to approach the limit block 3, so that the multiple groups of first rubber pads 4 and the second rubber pads 605 further squeeze the catheter, so as to achieve the final fixing effect of the catheter, so that during the treatment process, the multiple catheters are clearly arranged and not easy to move, and the first When the rubber pad 4 and the second rubber pad 605 squeeze the catheter, the spring 603 is compressed to a certain extent. When the medical staff needs to remove a certain catheter, they can push the push block 608 to the side away from the limit block 3, so that the movable block 604 moves slightly in the direction away from the limit block 3, and drives the slider 606 to further squeeze the spring 603, thereby making the first rubber pad 4 and the second rubber pad 605 on the upper side separate from the catheter, so the medical staff can remove the catheter. With this arrangement, the medical staff can achieve synchronous clamping and unclamping of all catheters by rotating the screw 607, but when a certain catheter needs to be removed, it can be achieved by a simple operation such as pushing the push block 608.
[0037] See also Figure 1 A transparent hollow plate 7 is installed on the top of each of the plurality of limit blocks 3 .
[0038] In this solution, staff can insert small cards into the transparent hollow plate 7 in advance, and mark the functions of multiple catheters on multiple small cards. When in use, the corresponding catheter can be fixed next to the corresponding limit block 3, thereby avoiding medical staff from confusing the catheter during treatment.
[0039] Working principle:
[0040] When in use, the medical staff connects the two ends of the multiple catheters to the machine and the patient respectively, then moves the bracket 1 to a suitable position, and then inserts any parts of the multiple catheter bodies between the adjacent first rubber pads 4 and second rubber pads 605, and the catheters are squeezed between them to achieve preliminary fixation. Then the medical staff rotates the screw 607 to move the screw 607 toward the inner end of the bracket 1, and then drives the movable rod 601 to move through the screw 607. The movable rod 601 slides on the multiple positioning blocks 5, thereby driving the multiple abutment blocks 602 to move, and the multiple abutment blocks 602 push the spring 603 and the slider 606 moves, thereby pushing the movable block 604 to approach the limit block 3, so that multiple groups of first rubber pads 4 and second rubber pads 605 further squeeze the catheter to achieve the final fixing effect of the catheter. When the medical staff needs to remove a certain catheter, they can push the dial block 608 to the side away from the limit block 3, thereby making the movable block 604 move slightly in the direction away from the limit block 3, and drive the slider 606 to further squeeze the spring 603, thereby making the first rubber pad 4 and the second rubber pad 605 on the upper side detach from the catheter, so the medical staff can remove the catheter.
[0041] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
