Description

Technical Field

[0001] The utility model relates to the technical field of dialysis pipelines, in particular to a device for facilitating waste liquid discharge from dialysis pipelines. Background Art

[0002] Hemodialysis is a type of blood purification technology. The equipment used mainly includes blood circuit tubing and dialyzers. The blood is drawn out of the body by a blood pump and sent to the dialyzer for purification. The purified blood enters a filter with a filter screen through the tube. The equipment used mainly includes blood circuit tubing and dialyzers. The blood is drawn out of the body by a blood pump and sent to the dialyzer for purification.

[0003] However, current dialysis tubing requires a separate hemostatic clamp to close the venous end of the tubing or a nurse to manually fold the tubing back when draining waste fluid. This method is very inconvenient and often does not drain completely, thus affecting the patient's recovery.

[0004] In order to solve the above problems, the present application proposes a device for facilitating the discharge of waste liquid from the dialysis pipeline. Utility Model Content

[0005] The utility model is intended to provide a device for facilitating the drainage of waste liquid from dialysis tubing, and is mainly used to solve the problem that when draining waste liquid from existing dialysis tubing, a hemostatic forceps must be prepared separately to clamp the venous end of the tubing or a nurse must manually fold the tubing back, resulting in the waste liquid often not being drained cleanly, thus affecting the patient's recovery.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] The top of the fixing block is provided with a pressure block, and the bottom of the pressure block is abutted against the outer wall of the tube body by the pressure block. The fixing block is extended out of the top of the fixing block, and the bottom of the pressure block is provided with a limit assembly on both sides of the pressure block. The limit assembly includes a sliding cavity provided on the bottom of the two sides of the pressure block, the internal sliding connection of the sliding cavity is limited, the inner wall of the sliding cavity is fixedly connected to the limit block on one side away from the limit block, the other end of the spring is fixedly connected to the limit block, the inner wall of the cavity is provided with a through groove matching the limit block, the inner wall of the through groove is provided with a push block, the fixed block is extended on one side of the push block, and the two sides of the pressure block are fixedly connected to the guide blocks, and the inner wall of the cavity is provided with a guide groove matching the guide block.

[0008] The working principle and beneficial effects of this utility model:

[0009] 1. Working principle: During the dialysis process, when the patient needs to discharge the waste fluid in the patient's body, the pressure block on the fixed block can be pressed to move it downward. When the bottom of the pressure block clamps the tube body, the pressure block on the fixed block is pressed to move it downward. When the pressure block clamps the tube body, the limit block will pop out under the action of the spring and engage with the through groove on the fixed block, so that the venous end of the dialysis pipeline can remain closed when the waste fluid is discharged, and the waste fluid can be discharged smoothly. When the waste fluid is completely discharged, press the push blocks on both sides of the fixed block to push the limit block to move into the sliding cavity. When the limit block is out of the through groove, the pressure block can move upward. At this time, the venous end of the pipeline can remain unobstructed and the waste fluid can no longer be discharged.

[0010] 2. Beneficial effect: The tube body can be clamped by pressing the fixing block provided on the tube body. The advantage of this arrangement is that when the patient is undergoing dialysis, medical staff no longer need to prepare hemostatic forceps separately or nurses do not need to manually fold the tube back. The venous end of the tube can be closed when draining waste liquid, ensuring smooth discharge of waste liquid, thereby making the use of the dialysis tube more convenient.

[0011] Preferably, the top of the guide block is fixedly connected to a magnet, and the top of the inner wall of the guide groove is fixedly connected to an iron sheet attracted by the magnet. When the medical staff presses the push blocks on both sides of the fixed block to make the limit block disengage from the through groove, the magnets arranged on the guide blocks on both sides of the pressing block and the iron sheet arranged on the inner wall of the guide groove are attracted to the iron sheet to move the pressing block upward, thereby further ensuring that the venous end pipeline remains smooth, and thus effectively ensuring the normal operation of the dialysis pipeline.

[0012] Preferably, sliders are fixedly connected on both sides of the push block, and a slide groove matching the slider is provided on the inner wall of the through slot. When the push block slides inside the through slot, the sliders provided on both sides of the push block and the slide groove provided on the inner wall of the through slot can better limit and guide the push block, thereby making the push block more stable when sliding inside the through slot, and effectively preventing the push block from separating from the fixed block, thereby effectively ensuring the normal use of the device.

[0013] Preferably, the number of springs inside the sliding cavity is not less than three, and the springs are distributed equidistantly inside the sliding cavity in a linear array. By setting the number of springs inside the sliding cavity to be not less than three, the squeezing force of the spring on the limit block can be greater, thereby making the limit block have a better limiting effect on the pressure block.

[0014] Preferably, a rubber pad is fixedly connected to the bottom of the pressing block, and the corners of the bottom of the rubber pad are all rounded. Since the rubber material has good wear resistance and elasticity, the rubber pad provided at the bottom of the pressing block can not only make the sealing effect of the tube body better after the pressing block presses the tube body, but also play a certain protective role on the tube body, thereby effectively extending the service life of the dialysis pipeline.

[0015] Preferably, the corners of the fixing blocks are all rounded. By setting the corners of the fixing blocks as rounded, people will not be scratched by the corners of the fixing blocks during use of the dialysis tubing, thereby making the dialysis tubing more practical.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4The dialysis line is convenient for draining waste liquid, comprising a tube body 1 and a venous end 2 fixedly connected at one end of the tube body 1, a fixing block 3 is fixedly connected to the end of the outer wall of the tube body 1 near the venous end 2, and the corners of the fixing block 3 are all rounded. The tube body 1 passes through the fixing block 3 and is fixedly connected between the fixing block 3. A cavity 4 is provided on the top of the fixing block 3, and a pressing block 5 is slidably connected to the inside of the cavity 4. By pressing the pressing block 5 to move it downward and press the tube body 1, the venous end 2 of the dialysis line can be closed when draining waste liquid. A rubber pad 17 is fixedly connected to the bottom of the pressing block 5, and the corners of the bottom of the rubber pad 17 are all rounded, which not only makes the sealing effect of the tube body 1 better after the pressing block 5 presses the tube body 1, but also plays a certain protective role for the tube body 1. The fixing block 3 is extended, and the bottom of both sides of the pressing block 5 is provided with a limiting component. After the bottom of the pressing block 5 presses the tube body 1, the pressing block 5 can be fixed by the limiting component, so that the venous end 2 pipeline remains tightly closed, ensuring the smooth discharge of waste liquid. Guide blocks 6 are fixedly connected on both sides of the pressing block 5, and a guide groove 7 matching the guide block 6 is provided on the inner wall of the cavity 4. The top of the guide block 6 is fixedly connected with a magnet 13, and the top of the inner wall of the guide groove 7 is fixedly connected with an iron sheet 14 attracted by the magnet 13. Through the magnets 13 set on the guide blocks 6 on both sides of the pressing block 5 and the iron sheet 14 set on the inner wall of the guide groove 7, the magnet 13 and the iron sheet 14 are attracted to each other to make the pressing block 5 move upward, thereby further ensuring that the venous end 2 pipeline remains smooth, thereby effectively ensuring the normal operation of the dialysis pipeline.

[0023] like Figure 2 and Figure 3 As shown, the limit assembly includes sliding cavities 8 at the bottom of both sides of the pressure block 5, the internal sliding connection of the sliding cavity 8 is limited to the limit block 9, and the inner wall of the sliding cavity 8 is fixedly connected to the side of the limit block 9. The number of springs 10 inside the sliding cavity 8 is not less than three, and the springs 10 are evenly distributed in a linear array inside the sliding cavity 8. The other end of the spring 10 is fixedly connected to the limit block 9, and the inner wall of the cavity 4 is provided with a through groove 11 matching the limit block 9. The inside of the through groove 11 is slidably connected to a push block 12, and a fixed block 3 extends from one side of the push block 12. Slide blocks 15 are fixedly connected on both sides of the push block 12, and the inner wall of the through groove 11 is provided with a sliding block matching the slide block 15 Slot 16. When it is necessary to discharge the waste liquid in the patient's body, the pressing block 5 on the fixed block 3 can be pressed to move it downward. When the pressing block 5 clamps the tube body 1, the limit block 9 will pop out under the action of the spring 10 and engage with the through groove 11 on the fixed block 3, so that the venous end 2 pipeline can remain closed when the dialysis pipeline discharges the waste liquid, and the waste liquid can be discharged smoothly. When the waste liquid is completely discharged, the pushing blocks 12 on both sides of the fixed block 3 are pressed to push the limit block 9 to move into the sliding cavity 8. When the limit block 9 is separated from the through groove 11, the pressing block 5 can move upward. At this time, the venous end 2 pipeline can remain unobstructed, and the waste liquid can no longer be discharged, making the use of the dialysis pipeline more convenient.

[0024] From the above, it can be seen that the specific implementation of the present utility model is as follows:

[0025] When the patient needs to discharge the waste liquid in the patient's body during dialysis, the pressing block 5 on the fixed block 3 can be pressed to move it downward. When the bottom of the pressing block 5 clamps the tube body 1, the limit block 9 will pop out under the action of the spring 10 and engage with the through groove 11 on the fixed block 3, so that the venous end 2 pipeline can remain closed when the dialysis pipeline discharges the waste liquid, and the waste liquid can be discharged smoothly. When the waste liquid is completely discharged, the pushing blocks 12 on both sides of the fixed block 3 are pressed to push the limit block 9 to move into the sliding cavity 8. When the limit block 9 is out of the through groove 11, the magnets 13 provided on the guide blocks 6 on both sides of the pressing block 5 and the iron sheet 14 provided on the inner wall of the guide groove 7, the magnets 13 and the iron sheet 14 are attracted to each other to make the pressing block 5 move upward, thereby further ensuring that the venous end 2 pipeline remains smooth, thereby effectively ensuring the normal operation of the dialysis pipeline.
