[0027] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] like Figure 1 As shown, this invention discloses a dialyzer clamp for stably holding the dialyzer during hemodialysis to ensure its effective operation. The dialyzer clamp of this invention includes a fixed clamp assembly, a movable clamp assembly, and a rotating ring assembly. The fixed clamp assembly and the rotating ring assembly are detachably connected to maintain the fixed clamp assembly in a fixed position. This detachable connection allows for separation of the two components for easy replacement and maintenance. The movable clamp assembly and the fixed clamp assembly are detachably rotated to ensure that they are rotated together in the working state and detachable in the maintenance state.

[0030] The various components of this invention will now be described in detail.

[0031] Specifically, the fixing clamp assembly of the present invention includes a fixing clamp 1 and a first sleeve 2. The fixing clamp 1 and the first sleeve 2 are integrally formed. The portion between the fixing clamp 1 and the first sleeve 2 is provided with a receiving cavity 3 for connecting to a movable clamp assembly. The movable clamp assembly is installed in the receiving cavity 3. The first sleeve 2 is used to connect to a rotating ring assembly to fix the fixing clamp assembly. The fixing clamp 1 has a downwardly extending second handle 4 at the junction with the first sleeve 2 for easy gripping when operating the dialyzer clamp. In addition, a protruding tube clamp 5 is provided on the outside of the fixing clamp 1. The tube clamp 5 can clamp the tubing used in the hemodialysis process to ensure that the tubing remains clean.

[0032] In this invention, the rotating ring assembly includes a rotating ring 6 and a second sleeve 7. The second sleeve 7 is integrally formed on the outer wall of the rotating ring 6 and is mated with the first sleeve 2. The axis of the second sleeve 7 is perpendicular to the axis of the rotating ring 6, and the rotating ring 6 is provided with a first connecting hole 26, which is connected to the fixing clamp assembly via a pin 8.

[0033] In this invention, the movable clamp assembly includes a movable clamp 9, which has a connecting portion 10 extending into the receiving cavity 3. The connecting portion 10 extends outward from the movable clamp 9 and is rotatably connected to the receiving cavity 3. The movable clamp 9 has a first handle 11, which is paired with a second handle 4. When using the dialyzer clamp, the first handle 11 is gripped tightly with the hand, and the second handle 4 is gripped with the fingers and force is applied to easily pry open the movable clamp 9.

[0034] When the connecting part 10 is connected to the receiving cavity 3, the connecting part 10 is connected to the receiving cavity 3 through a connecting assembly. Specifically, the connecting assembly includes a first spring 14, a sliding sleeve 15, and a connecting rod 16. The connecting part 10 abuts against the bottom of the sliding sleeve 15. One end of the first spring 14 is located inside the sliding sleeve 15, and the other end abuts against the connecting rod 16. A disc can be connected to the end of the connecting rod 16 to provide support for the first spring 14. In addition, the internal through hole of the first sleeve 2 is a stepped hole adapted to the connecting rod 16. The disc of the connecting rod 16 is matched with the step of the stepped hole, so that the disc of the connecting rod 16 is confined within the first sleeve 2. At the same time, the rod body of the connecting rod 16 is also fitted with a second spring 27. The second spring 27 can buffer the movement of the connecting rod 16, so as to ensure the stability of the force applied when gripping the first handle 11 and the second handle 4. In this invention, since the first sleeve 2 has a stepped portion, the stepped portion of the first sleeve 2 can be inserted into the second sleeve 7 and dock with the second sleeve 7. The connecting part 10 is provided with a sliding part that abuts against the sliding sleeve 15. The surface of the sliding part that abuts against the sliding sleeve 3 is an arc-shaped surface to ensure that when force is applied to the first handle 11, the movable chuck 9 can rotate around the rotational connection position.

[0035] In this invention, the connecting part 10 is connected to the receiving cavity 3 via a rotating shaft 12. The rotating shaft 12 is a stepped shaft, meaning that both ends of the rotating shaft 12 have steps of the same specifications, and the diameter of the stepped portion is smaller than the diameter of the middle portion. Simultaneously, a second connecting hole 13 that mates with the rotating shaft 12 is provided on the cavity wall of the receiving cavity 3, and a third connecting hole is provided in the connecting part 10. The second connecting hole 13 is a gourd-shaped hole, wherein the small portion of the second connecting hole 13 matches the step of the rotating shaft 12, and the large portion and the third connecting hole match the middle portion of the rotating shaft 12. Under normal conditions, the rotating shaft 12 is pressed and positioned in the small portion of the second connecting hole 13 under the action of the first spring 14 and the sliding sleeve 15. During disassembly, the movable chuck 9 can be forcefully pushed to allow the rotating shaft 12 to enter the large portion of the second connecting hole 13, and then the rotating shaft 12 can be removed from the second connecting hole 13 to remove the movable chuck 9 from the fixed chuck 1.

[0036] In this invention, the end of the connecting rod 16 away from the disk is connected to the first connecting hole 26 via a pin 8, thereby positioning the connecting rod 16. It should be noted that the total length of the first sleeve 2 and the second sleeve 7 after docking is less than the distance from the bottom of the sliding sleeve 15 of the first spring 14 in its natural state to the connection position of the connecting rod 16 and the first connecting hole 26. At the same time, the length of the connecting rod 16 is equal to the distance from the stepped part of the first sleeve 2 to the first connecting hole 26, so as to ensure that when the connecting rod 16 is positioned and tightened by the pin 8, the first sleeve 2 and the second sleeve 7 can be docked precisely.

[0037] In this invention, such as Figure 2 As shown, anti-slip ribs 17 are provided on the inner wall of the fixed clamp 1. The anti-slip ribs 17 can increase the friction between the fixed clamp 1 and the dialyzer to prevent the dialyzer from sliding off.

[0038] In this invention, such as Figure 3 As shown, when installing the rotating ring 6, a fixing sleeve 18 can be first fitted into the support rod, and the rotating ring 6 is then fitted onto the outside of the fixing sleeve 18. A retaining ring 19 is provided at the top of the fixing sleeve 18, which is adapted to the rotating ring 6, such that the bottom surface of the retaining ring 19 abuts against the top surface of the rotating ring 6. The bottom of the fixing sleeve 18 has several symmetrically distributed positioning screw holes 20. A fastening ring 21 is fitted onto the lower part of the fixing sleeve on the support rod. The fastening ring 21 has a fourth connecting hole 22 corresponding to each of the positioning screw holes 20. Fastening screws 23 are connected to the positioning screw holes 20 and the fourth connecting holes 22, so that the fixing sleeve 18 is positioned in the support rod by the fastening ring 21 and the fastening screws 23. Furthermore, the distance from the positioning screw hole 20 to the bottom surface of the retaining ring 19 should be consistent with the length of the rotating ring 6, and the outer diameter of the fastening ring 21 should be consistent with the outer diameter of the retaining ring 19, so that the rotating ring 6 is positioned between the fastening ring 21 and the retaining ring 19.

[0039] In this invention, a corrugated gasket 24 is connected between the rotating ring 6 and the fixed sleeve 18. The corrugated gasket 24 can apply a preload to the rotating ring 6, ensuring a tight connection between the rotating ring 6 and the fixed sleeve 18 and preventing the rotating ring 6 from rotating. Simultaneously, corrugated mating surfaces 25 are provided at the mating points of the first sleeve 2 and the second sleeve 7, allowing the first sleeve 2 and the second sleeve 7 to be relatively tightly joined and preventing easy relative rotation.
