Technical Field

[0001] This utility model relates to the field of dialyzer technology, specifically an infection-proof hemodialysis device. Background Technology

[0002] Dialyzers primarily utilize the principle of semipermeable membranes, introducing the patient's blood and dialysate simultaneously into the dialyzer. The two flow in opposite directions on either side of the dialysis membrane, using the solute gradient, osmotic gradient, and water pressure gradient across the membrane to remove toxins and excess water while replenishing the body's necessary substances.

[0003] The delivery tubing of most existing dialyzers is directly inserted into the dialyzer connector without any securing device. When medical staff move around, they can easily bump into the delivery tubing, causing it to loosen from the dialyzer. If harmful substances from the outside enter the delivery tubing, it can easily cause infection in the patient, which has a great impact on the patient's health.

[0004] Therefore, those skilled in the art have provided an infection-resistant hemodialysis device to address the problems mentioned in the background section. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5In this embodiment of the present invention, an infection-proof hemodialysis machine includes a main body 1 of the hemodialysis machine. The main body 1 is provided with a first connector 2 for conveying blood, and a second connector 3 for conveying dialysate is provided on the outer wall of the main body 1. A delivery tube 4 is provided on the first connector 2 and the second connector 3 respectively. The delivery tube 4 is provided with a fastening component to prevent the delivery tube 4 from falling off the first connector 2 and the second connector 3. The main body 1 is a conventional semi-permeable membrane hemodialysis machine. The first connector 2 is installed on the top and bottom of the main body 1 respectively for conveying blood. The second connector 3 is installed on the outer wall of the main body 1 respectively and can convey dialysate. The delivery tube 4 is inserted into the first connector 2 and the second connector 3 respectively for conveying blood and dialysate.

[0023] In one embodiment, the fastening assembly includes a nylon sleeve 5 mounted on the delivery pipe 4. The nylon sleeve 5 has multiple movable grooves 6. A pressure block 7 is located on the nylon sleeve 5 and inside the movable grooves 6. A threaded tube 8 is provided on the nylon sleeve 5, and a rotating ring 9 is screwed onto the threaded tube 8. A limiting ring 10 is provided on the nylon sleeve 5. The nylon sleeve 5 is fixedly fitted onto the end of the delivery pipe 4. Multiple movable grooves 6 are equidistantly located on the outer wall of the nylon sleeve 5. Multiple pressure blocks 7 are integrally formed on the nylon sleeve 5 and are respectively located inside the movable grooves 6. The pressure blocks 7 are made of nylon and have a certain degree of elasticity. When the pressure blocks 7 are pressed by external force, they can... The deformation of block 7 allows it to press against the outer wall of the conveying pipe 4, making the connection between the conveying pipe 4 and connector 1 2 and connector 2 3 more secure and preventing the conveying pipe 4 from loosening. The threaded pipe 8 is fixedly sleeved on one end of the nylon sleeve 5. The rotating ring 9 is screwed onto the threaded pipe 8. The rotating ring 9 rotates on the threaded pipe 8, allowing it to approach the block 7. After the rotating ring 9 contacts the block 7, it can press against the block 7, making the block 7 press against the conveying pipe 4 and preventing the conveying pipe 4 from falling off. The limiting ring 10 is fixedly sleeved on the nylon sleeve 5, limiting the movement of the rotating ring 9 and the pressing ring 11 and preventing the pressing ring 11 from detaching from the threaded pipe 8 along with the rotating ring 9.

[0024] Wherein, the pressure block 7 is higher than the movable groove 6, and the thickness of the pressure block 7 is greater than the depth of the movable groove 6. When the rotating ring 9 moves toward the pressure block 7, the end of the rotating ring 9 can contact the pressure block 7. As the rotating ring 9 continues to move, the pressure block 7 can be pressed into the movable groove 6 by the rotating ring 9. When the rotating ring 9 presses the pressure block 7, it can make the pressure block 7 flush with the top of the outer wall of the nylon sleeve 5. Since the thickness of the pressure block 7 is greater than the depth of the movable groove 6, the pressure block 7 can press on the outer wall of the conveying pipe 4, which can cause the outer wall of the conveying pipe 4 to be concave and deformed, which can increase the squeezing force of the pressure block 7 on the conveying pipe 4, and can make the connection between the conveying pipe 4 and the connector 1 2 and connector 2 3 more secure.

[0025] Based on the above embodiments, specifically, a pressure ring 11 is rotatably connected to the rotating ring 9. The pressure ring 11 is provided with an umbrella-shaped surface 12. The pressure ring 11 is rotatably connected to the side wall of the rotating ring 9, and the umbrella-shaped surface 12 is opened on the inner wall of the pressure ring 11. When the rotating ring 9 rotates on the threaded tube 8 to press the pressure block 7, the umbrella-shaped surface 12 on the pressure ring 11 can fit tightly with the outer wall of the pressure block 7, which can increase the contact area between the pressure ring 11 and the pressure block 7, and can prevent the pressure block 7 from being directly pressed by the end of the pressure ring 11 and being damaged. The pressure ring 11 is rotatably connected to the rotating ring 9. When the pressure ring 11 presses the pressure block 7, under the action of the friction between the umbrella-shaped surface 12 and the pressure ring 11, the pressure ring 11 can stop rotating, and the pressure ring 11 can slide along the pressure block 7 and press the pressure block 7, which can prevent the pressure ring 11 from rotating with the rotating ring 9 and causing unnecessary wear on the pressure ring 11.

[0026] More specifically, the rotating ring 9 is provided with multiple levers 13, which are fixedly installed on the outer wall of the rotating ring 9, so that medical staff can rotate the rotating ring 9 by moving the levers 13, which can prevent slippage when the rotating ring 9 is rotated directly.

[0027] Furthermore, chamfers 14 are respectively provided on the ends of connector 2 and connector 3, which facilitates medical personnel to insert the delivery tube 4 into connector 2 and connector 3.

[0028] Based on the above embodiments, more specifically, the first connector 2 and the second connector 3 are respectively provided with a plurality of anti-detachment retaining rings 15. The anti-detachment retaining rings 15 are integrally formed on the outer wall of the first connector 2 and the second connector 3. After the delivery pipe 4 is inserted into the first connector 2 and the second connector 3, the anti-detachment retaining rings 15 can cause the inner wall of the delivery pipe 4 to be concave and deformed, which can increase the friction between the inner wall of the delivery pipe 4 and the first connector 2 and the second connector 3, and further prevent the delivery pipe 4 from loosening.

[0029] In use, firstly, insert the delivery pipe 4 into the connector 2. As the delivery pipe 4 is inserted, the anti-disengagement ring 15 squeezes the inner wall of the delivery pipe 4 and causes it to deform inward. As the delivery pipe 4 continues to be inserted, the end of the delivery pipe 4 abuts against the end of the main body 1. At this point, the delivery pipe 4 is inserted into place. Then, by turning the lever 13, the rotating ring 9 is driven to rotate. As the rotating ring 9 rotates, it moves on the threaded pipe 8 and approaches the pressure block 7. Subsequently, the umbrella-shaped surface 12 on the pressure ring 11 contacts the pressure block 7. Afterwards, the pressure block 7 is pressed by the pressure ring 11 and retracts into the movable groove 6. As the pressure ring 11 continues to move and press the pressure block 7, the pressure block 7 gradually squeezes the outer wall of the conveying pipe 4. When the end of the pressure ring 11 abuts against the limiting ring 10, the rotating ring 9 and the pressure ring 11 stop moving, and the position of the pressure block 7 is fixed by the pressure ring 11. The pressure block 7 continues to squeeze the outer wall of the conveying pipe 4. At this time, the conveying pipe 4 is firmly installed on the connector 2. Then, the other conveying pipes 4 can be installed on the connector 3 according to the above steps.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
