Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, in particular to a bedside fixing device for nursing in a hemodialysis room. Background Art

[0002] Hemodialysis is a common form of renal replacement therapy used to treat patients with chronic renal failure or acute kidney injury. During hemodialysis, a patient's blood passes through a dialyzer, where it exchanges substances with a dialysate across a semipermeable membrane to remove metabolic waste and excess water from the body. Hemodialysis catheters are a means of establishing vascular access and are typically used in patients who cannot establish an arteriovenous fistula or other vascular access.

[0003] During hemodialysis, it is very important to fix the hemodialysis catheter to ensure that the catheter does not move or fall off during the dialysis process. In order to ensure that the catheter does not bend, special medical tape is currently used for fixation. However, the tape is fixed at only one point, and its fixing effect is relatively poor, which can easily cause the catheter to swing, and the swing of the catheter can also easily cause the tape to loosen or curl, affecting the fixation effect. Moreover, when the tape is fixed, the tape will adhere to both the catheter and the bedside, and the catheter will be fixed tightly, leaving no room for movement. In the event of an accident, such as the patient turning over, the catheter will be pulled, and the catheter will have no buffer distance, which can easily cause pulling on the connection between the catheter and the patient, causing discomfort to the patient. Utility Model Content

[0004] The purpose of the utility model is to provide a bedside fixing device for hemodialysis room nursing, which can improve the fixing effect of the catheter at the bedside and provide a buffer space for the catheter after the catheter is pulled.

[0024] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0025] The embodiment of the present invention is a bedside fixing device for hemodialysis room nursing, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, it includes a vertically arranged first fixed block 7, and two independent second fixed blocks 1 are vertically arranged on one side of the second fixed block 1. Because two catheters are provided, the two catheters are restricted respectively by the two second fixed blocks 1. The tops of the second fixed blocks 1 are hinged to the first fixed block 7 and swing up and down. A frame 13 is provided on the side of the second fixed block 1 away from the first fixed block 7, and the side of the frame 13 away from the second fixed block 1 has no side wall. The frame 13 is a rectangular frame that is connected from top to bottom, and the frame 13 has no right side wall, so the catheter can be placed in the frame 13.

[0026] A movable rod 3 is horizontally arranged between the tops of the first fixed block 7 and the second fixed block 1, one end of the movable rod 3 is fixed to the first fixed block 7, and the other end of the movable rod 3 is hinged to the second fixed block 1 and swings up and down. A through hole communicating front and back is opened at the right end of the movable rod 3, and a rotating shaft is independently installed in the through hole. The front and rear ends of the rotating shaft are both fixed with mounting blocks beyond the through hole, and the mounting block is fixed to the top of the second fixed block 1. The rotating shaft rotates in the right end of the movable rod 3, so that the right end of the movable rod 3 is hinged to the second fixed block 1 and swings up and down. The movable rod 3 can create a distance between the second fixed block 1 and the first fixed block 7, so that the second fixed block 1 can be tilted.

[0027] An adjusting tube 10 is horizontally arranged between the second fixing block 1 and the bottom of the first fixing block 7. An adjusting rod 11 is independently installed in the adjusting tube 10. A first bolt for fixing the adjusting rod 11 is provided on the adjusting tube 10. A first threaded hole that is threadedly matched with the first bolt is opened on the side wall of the adjusting tube 10. The screw of the first bolt passes through the first threaded hole and is pressed on the adjusting rod 11, thereby fixing the adjusting rod 11 in the adjusting tube 10. One end of the adjusting tube 10 is hinged to the first fixing block 7 and swings up and down. The connection method of the adjusting tube 10 and the first fixing block 7 is consistent with the connection method of the movable rod 3 and the second fixing block 1. One end of the adjusting rod 11 passes through the adjusting tube 10. The joint tube 10 is hinged to the second fixed block 1 and swings up and down. The connection method of the adjusting rod 11 to the second fixed block 1 is consistent with the connection method of the movable rod 3 to the second fixed block 1. Because the adjusting tube 10 and the adjusting rod 11 are hinged to the first fixed block 7 and the second fixed block 1 respectively, after the combined length of the adjusting tube 10 and the adjusting rod 11 changes, the distance between the bottom of the second fixed block 1 and the first fixed block 7 will change, and the top of the second fixed block 1 is hinged to the movable rod 3 and will rotate in place, thereby tilting the second fixed block 1; the content of this paragraph as a whole constitutes an adjustment mechanism for adjusting the distance between the second fixed block 1 and the first fixed block 7.

[0028] Of course, in some embodiments, the adjustment mechanism can also be a threaded fit between the adjustment tube 10 and the adjustment rod 11, the adjustment rod 11 is a screw, the inner side wall of the adjustment tube 10 is provided with an internal thread, and the adjustment tube 10 and the adjustment rod 11 are respectively covered with a connecting tube, the connecting tube is hinged to the first fixed block 7 and the second fixed block 1, and bearings are installed between the connecting tube and the adjustment tube 10 and the adjustment rod 11, and the adjustment tube 10 and the adjustment rod 11 are respectively connected to the connecting tube through the bearings, so that the adjustment tube 10 and the adjustment rod 11 can rotate independently.

[0029] A "C"-shaped buckle 15 is horizontally arranged in the frame 13. The buckle 15 is made of elastic material, which is elastic plastic. The inner diameter of the buckle 15 is consistent with the outer diameter of the catheter in a natural state, or the inner diameter of the buckle 15 is slightly smaller than the outer diameter of the catheter. The elasticity of the buckle 15 opens the opening of the buckle 15 and the catheter is placed in the buckle 15.

[0030] Several springs 12 are horizontally fixed between the buckle 15 and the frame 13. There are three springs 12. Springs 12 are horizontally fixed on the front, back and left sides of the buckle 15. The buckle 15 is connected to the frame 13 through the springs 12, and the buckle 15 can have a certain expansion space to facilitate the insertion of the catheter into the buckle 15. Of course, in some embodiments, the left side of the buckle 15 can also be directly fixed to the left inner wall of the frame 13, and there is a gap between the buckle 15 and the front and back side walls of the frame 13.

[0031] The above two paragraphs constitute a clamping mechanism for fixing the catheter; of course, in some embodiments, the clamping mechanism can also include two independent and parallel clamping blocks, and a spring is installed between the clamping block and the inner wall of the frame 13. Preferably, the clamping block is an arc-shaped structure, and the two clamping blocks are tubular in structure as a whole. When the spring is in a natural state, the two clamping blocks clamp the catheter.

[0032] The outer wall of the frame 13 is provided with a roller 16. There are two rollers 16. The rollers 16 are installed on the front and rear side walls of the frame 13. The rollers 16 are directional wheels. The outer side of the frame 13 is vertically provided with two parallel baffles 2 that are perpendicular to the second fixed block 1. The frame 13 is located between the two baffles 2, and the baffles 2 are fixed to the second fixed block 1. Figure 1As shown in the middle position, the second fixed block 1 is located on the right side of the first fixed block 7. Two baffles 2 are fixed parallel to the right side wall of the second fixed block 1 front and back. The two baffles 2 and the second fixed block 1 as a whole form a "C" - shaped structure. On the side of the baffle 2 close to the frame 13, a chute 2.1 is provided for the roller 16 to insert and roll along the length direction of the baffle 2. The top of the chute 2.1 is open, which allows the roller 16 to disengage from between the two baffles 2. Of course, the chute 2.1 has a bottom to prevent the roller 16 from falling off from the bottom of the chute 2.1. By the roller 16 sliding in the chute 2.1, on the one hand, it means that the frame 13 can be disengaged from between the two baffles 2, and on the other hand, it enables the frame 13 to slide up and down. Of course, in the natural state, due to its own weight, the buckle 15 and the frame 13 are located at the bottom of the chute 2.1. When the catheter is pulled, its buckle 15 is fixed to the catheter, so it will drive the buckle 15 and the frame 13 to slide upward for buffering. And when the patient feels a strong pulling force, the patient will immediately react, so the patient will not make big movements and will carefully return to the original position, and the frame 13 and the buckle 15 will reset under their own weight. Of course, in order to reduce the deviation of the frame 13 during the upward movement, 3 rollers 16 can also be provided. Rollers are also fixed on the left side wall of the frame 13, and a chute is provided on the right side wall of the second fixed block 1. The content of this paragraph as a whole constitutes a moving mechanism that enables the frame 13 to move up and down freely.

[0033] Of course, in some embodiments, the moving mechanism can also replace the roller 16 with a fixed rod. The fixed rod is fixed to the frame 13, and a first chute for the fixed rod to insert and slide up and down is provided on the baffle 2. One end of the fixed rod is located in the first chute and is fixedly sleeved with a bearing, and the outer ring of the bearing contacts the first chute.

[0034] A limiting plate 14 for blocking the frame 13 is horizontally fixed at the bottom of the baffle 2. The limiting plate 14 is horizontally fixed at the bottom of the rear side of the front baffle 2, and the limiting plate 14 is horizontally fixed at the bottom of the front side of the rear baffle 2. A gap is left between the two limiting plates 14 to avoid the limiting plate 14 from blocking the catheter, and the maximum distance of the downward movement of the frame 13 is controlled by the limiting plate 14 to prevent the frame from disengaging from the bottom of the two baffles 2.

[0035] A first connecting block 4 is vertically arranged on the top of the first fixing block 7. The thickness and width of the first connecting block 4 are smaller than those of the first fixing block 7. A sliding groove for the first connecting block 4 to insert and slide up and down is formed on the top of the first fixing block 7. A second bolt for fixing the first connecting block 4 in the sliding groove is arranged on the first fixing block 7. A clamping block 6 with an inverted "U" - shaped structure is fixed on the top of the first connecting block 4; A second connecting block 8 is vertically arranged at the bottom of the first fixing block 7. A bottom plate 9 is horizontally fixed at the bottom of the second connecting block 8, and the bottom plate 9 is located on the side far from the second fixing block 1. The second fixing block 1 is located on the right side of the first fixing block 7. The bottom plate 9 is fixed at the left - bottom of the second connecting block 8. When in use, place the bottom plate 9 at the bottom of the edge of the hospital bed, then slide the first connecting block 4 in the sliding groove to make the clamping block 6 hang on the top of the hospital - bed guardrail, and then slide the first connecting block 4 in the first fixing block 7 to adjust the combined length of the first connecting block 4 and the first fixing block 7, so that the clamping block 6 is closely attached to the guardrail of the hospital bed and the bottom plate 9 is closely attached to the bottom of the edge of the hospital bed. Then, fix the first connecting block 4 in the sliding groove through the first bolt, and further fix the first fixing block 7 on the hospital - bed guardrail.

[0036] The second connecting block 8 is fixed to the bottom of the first fixing block 7. The thickness of the second connecting block 8 is smaller than that of the first fixing block 7. Its installation is convenient. The first fixing block 7 is fixed by clamping through the clamping block 6 and the bottom plate 9. And the thickness of the second connecting block 8 is smaller than that of the first fixing block 7, so that the second connecting block 8 is closely attached to the edge of the hospital bed, and the first fixing block 7 is located inside the guardrail of the hospital bed; Of course, in some embodiments, a first sliding groove for the second connecting block 8 to insert may also be formed at the bottom of the first fixing block 7, and a fourth bolt for fixing the second connecting block 8 in the first sliding groove is arranged at the bottom of the first fixing block 7.

[0037] The above two paragraphs together constitute a fixing mechanism for fixing the first fixing block 7 on the hospital - bed guardrail. Of course, in some embodiments, the fixing mechanism can also be without the clamping block 6 and the first connecting block 4. Replace the bottom plate 9 with an installation groove in a "C" - shaped structure. A third bolt is arranged at the bottom of the installation groove. The installation groove is clamped on the edge of the hospital bed, and the installation groove is fixed to the edge of the hospital bed through the third bolt, so as to fix the first fixing block 7 to the hospital bed.

[0038] A limiting groove 5 is fixedly provided at the top of the clamping block 6 corresponding to the second fixing block 1. There are two limiting grooves 5, and the limiting groove 5 is integrally in a "C" - shaped structure. The limiting groove 5 includes a bottom plate, and limiting plates are vertically fixed at the tops of the front and rear ends of the bottom plate. The bottom plate and the two limiting plates integrally form a "C" - shaped structure with an upward opening. Since the clamping block 6 is stuck on the top of the hospital bed guardrail, the catheter that was originally placed on the top of the hospital bed guardrail is located in the limiting groove 5. Placing the catheter in the limiting groove 5 can prevent the catheter from sliding on the top of the clamping block 6 and increase the limiting effect on the displacement of the catheter.

[0039] Working principle:

[0040] During use, make the bottom plate 9 located at the bottom of the edge of the hospital bed, then slide the first connecting block 4 in the sliding groove on the top of the first fixing block 7, buckle the clamping block 6 on the top of the hospital bed guardrail, and then fix the first connecting block 4 in the first fixing block 7 with the first bolt, so as to fix the first fixing block 7 on the hospital bed guardrail; then, according to the inclination of the hemodialysis catheter on the hospital bed guardrail, move the adjusting rod 11 in the adjusting tube 10 to adjust the inclination of the second fixing block 1, so that the inclination angle of the second fixing block 1 is consistent with the inclination angle of the catheter on the outside of the hospital bed. Then, clamp the catheter in the buckle 15 to complete the fixation of the catheter. The part of the catheter on the clamping block 6 is located in the limiting groove 5, which can prevent the catheter from sliding horizontally on the top of the clamping block 6 and increase the fixing effect. Moreover, through the fixation of the buckle 15 and the fact that the catheter is located between the two baffle plates 2, the two baffle plates 2 limit the catheter, reducing the situation of horizontal displacement of the catheter, greatly enhancing the fixing effect of the catheter. When the patient turns over and accidentally pulls the catheter, since the buckle 15 is located in the frame 13 and the frame 13 can slide freely between the two baffle plates 2 through the rollers 16, after the catheter is pulled, the buckle 15 has a certain distance to move, playing a certain buffering role and reducing the discomfort caused to the patient.
