Description

Technical Field

[0001] The present invention relates to the technical field of hemodialysis pipelines, and in particular to a pipeline leakage-proof connection device. Background Art

[0002] Hemodialysis is a key medical treatment for patients with end-stage renal disease. It removes waste and excess water from the patient's blood through an artificial semipermeable membrane to replace the filtering function of the damaged kidneys. During the dialysis process, the dialysis tubing needs to be sealed with a connecting device to ensure that the blood can circulate safely and effectively in the dialysis system and the patient's body.

[0003] For example, the Chinese patent with publication number CN221845639U proposes a hemodialysis tubing leakage-proof connection device. The component is provided with a sleeve. When the dialysis tube and the indwelling tube are connected, the sleeve is rotated, and the sleeve does not drive the dialysis tube to rotate, thereby avoiding the situation where the dialysis tube rotates in the forward direction and becomes loose due to the elasticity of the dialysis tube. The block is stuck on the inner side of the card slot to prevent the indwelling tube and the sleeve from rotating in the reverse direction and becoming loose, effectively maintaining high-efficiency sealing performance, improving the safety and comfort of the patient's dialysis treatment, simple installation, and improving work efficiency. By setting a splint, the dialysis tube is fixed to the bed sheet to prevent the dialysis tube from falling off from the dialysis machine due to accidental pulling, thereby improving safety. However, in this scheme, only one sealing ring is used for sealing between the dialysis tube and the indwelling tube. When the sealing ring is damaged, the dialysate will flow into the sleeve, resulting in leakage, and the sealing effect is average. For this reason, we propose a pipeline leakage-proof connection device. Summary of the Invention

[0004] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a pipeline anti-leakage connection device to solve the problems mentioned in the background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A pipeline leakage-proof connection device comprises: a dialysis tube, one end of which is provided with a sleeve, and an indwelling tube is provided inside the sleeve; a connecting assembly, which is arranged inside the sleeve and is used to connect the dialysis tube and the indwelling tube, the connecting assembly comprising a connecting block, the connecting block is connected to the outer wall surface of the indwelling tube, the inner wall of the sleeve is provided with a connecting groove, the connecting groove and the connecting block are threadedly connected together, one side of the dialysis tube is connected to the first sealing gasket, and the inner wall of the sleeve is connected to the second sealing gasket. By rotating the sleeve, the connecting block and the connecting groove are threadedly connected together, so that the dialysis tube and the indwelling tube are connected together, which is convenient for patients to perform hemodialysis. The first sealing gasket and the second sealing gasket are used in combination to seal the connection between the dialysis tube and the indwelling tube to avoid leakage.

[0007] By adopting the above technical solution and setting up a connecting assembly, when in use, medical staff inserts the sleeve into one end of the indwelling tube, and rotates the sleeve to thread the connecting block and the connecting groove together, so that the dialysis tube and the indwelling tube are connected together, which is convenient for patients to perform hemodialysis. The first sealing gasket and the second sealing gasket are used in combination to seal the connection between the dialysis tube and the indwelling tube, avoiding leakage and improving the sealing performance.

[0008] Preferably, the connecting assembly further includes: a movable groove, the movable groove being opened on one side of the interior of the indwelling tube, and a movable plate being movably connected inside the movable groove; a guide tube, the guide tube being connected to one side of the interior of the indwelling tube, and the guide tube and the movable plate being movably sleeved together; two rotating rods, the two rotating rods being movably connected to the interior of the movable groove respectively, one end of the rotating rod being provided with a first thread groove, and the other end of the rotating rod being provided with a second thread groove, the thread directions of the first thread groove and the second thread groove being opposite, and the first thread groove and the movable plate being threadedly connected together; an extrusion block, the extrusion block being movably connected to one end of the rotating rod, and the extrusion block being threadedly connected to the second thread groove.

During the movement, the movable plate drives the rotating rod to rotate, and the rotation of the rotating rod can drive the extrusion block to move in the opposite direction of the movement of the movable plate. The extrusion block applies pressure to the second sealing gasket, thereby increasing the sealing performance between the second sealing gasket and the sleeve, thereby improving the sealing effect.

[0012] Preferably, a third sealing gasket is connected to one side of the extrusion block.

[0015] By adopting the above technical solution and setting a torsion spring, during use, when the rotating rod rotates, the torsion spring is driven to rotate and contract. After the dialysate stops flowing, the thrust restriction on the movable plate is released. The potential energy generated by the contraction of the torsion spring drives the mounting ring to rotate and reset, thereby resetting the movable plate and the extrusion block, thereby ensuring the use of the connecting assembly.

[0016] Preferably, the outer wall surface of the dialysis tube is connected with a rotating groove, and the inner side of the sleeve is connected with a rotating ring, and the rotating ring is movably sleeved with the rotating groove.

[0017] By adopting the above technical solution and providing a rotating ring, the sleeve can be limited in rotation by the rotating ring during connection, which makes it convenient for medical staff to maintain the stability of the sleeve rotation when rotating the sleeve, thereby improving practicality.

In combination with the anti-slip pad, the dialysis tube is fixed to the edge of the bed, which is convenient for use and prevents the dialysis tube from falling off the dialysis machine due to accidental pulling, thereby improving safety.

[0020] Preferably, a detection groove is provided on the outer wall of the sleeve, and a water immersion sensor is connected to the interior of the detection groove.

[0021] By adopting the above technical solution and setting a water immersion sensor, the internal situation of the casing can be monitored in real time through the water immersion sensor during use, and leakage can be discovered in time, thereby improving practicality.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] By setting up a connecting component, when in use, medical staff inserts the sleeve into one end of the indwelling tube and rotates the sleeve to thread the connecting block and the connecting groove together, so that the dialysis tube and the indwelling tube are connected together, which is convenient for the patient to perform hemodialysis. The first sealing gasket and the second sealing gasket are used in conjunction with each other to seal the connection between the dialysis tube and the indwelling tube to avoid leakage and improve the sealing performance. The dialysate will enter the interior of the indwelling tube through the dialysis tube, and the movable plate will be subjected to the force generated by the flow of the dialysate, driving the movable plate to move toward the front end of the indwelling tube. The movable plate drives the rotating rod to rotate during the movement, and the rotation of the rotating rod can drive the extrusion block to move in the opposite direction of the movement of the movable plate. The extrusion block applies pressure to the second sealing gasket to increase the sealing performance between the second sealing gasket and the sleeve, thereby improving the sealing effect.

[0024] By setting a baffle, when in use, when the movable plate moves forward, it drives the baffle to move in the limiting groove, so that the baffle is expanded, and a closed cavity is formed by the baffle and the movable plate to avoid contact between the dialysate and the rotating rod, which causes the dialysate to be contaminated and affects the use, thereby improving safety. By setting a third sealing gasket, when in use, when the extrusion block approaches the second sealing gasket, it drives the third sealing gasket to move, so that the third sealing gasket is fitted with the second sealing gasket, and a second layer of sealing protection is performed, further improving the sealing effect.

[0025] By setting a torsion spring, during use, when the rotating rod rotates, it drives the torsion spring to rotate and contract. After the dialysate stops flowing, the thrust restriction on the movable plate is released, and the potential energy generated by the contraction of the torsion spring drives the mounting ring to rotate and reset, thereby resetting the movable plate and the extrusion block to ensure the use of the connecting assembly. By setting a fixed plate, during use, the operator can place the placement plate on the bed railing, and rotate the rotating rod to drive the fixed plate to move toward the railing.
