Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a filter clip and hemodialysis equipment that are easy to assemble and disassemble. Background Technology

[0002] Continuous renal replacement therapy (CRRT) is a type of continuous renal replacement therapy that works by continuously and slowly removing water and solutes through extracorporeal blood circulation to replace kidney function. The filter is the core component used to remove waste and fluids from the blood; before use, the filter is clamped onto the hemodialysis machine using filter clips.

[0003] Currently, filter clamp installation and removal are quite cumbersome, requiring the locking part to be fixed by tightening screws or by rigidly fitting the locking part through the fixing rod. Therefore, when replacing the filter clamp, it is necessary to first loosen the nut on the fixing rod, then remove the filter clamp, and finally retighten the nut on the fixing rod, making the whole process rather troublesome.

[0034] 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.

[0035] Figures 1 to 8 The diagram shown is a structural schematic of one embodiment of a filter clip that is easy to assemble and disassemble according to the present invention. Its main body includes a base 100, a filter clip body 200, and a locking mechanism 300.

[0036] The base 100 is used for mounting and fixing the filter clamp body 200. At the end of the base 100 away from the filter clamp body 200, mounting ears 130 are spaced apart along the circumference of the base 100. Each mounting ear 130 has a mounting hole 1310. During installation, the mounting ears 130 are inserted into the interior of the main unit of the device and fixed to the front end of the device with screws.

[0037] The filter clamp body 200 includes a connecting section 210 detachably connected to the base 100 and a clamping section 220 for clamping the filter. The connecting section 210 can be connected to or separated from the locking mechanism 300, thereby realizing the connection or separation of the filter clamp body 200 and the base 100. Specifically, the connecting section 210 is provided with a cavity 2110 for accommodating the locking mechanism 300, and the top end of the connecting section 210 is provided with a telescopic hole 2120 communicating with the cavity 2110. Preferably, in this embodiment, in order to further facilitate the clamping of the filter, the clamping section 220 includes a first movable arm 2210 and a second movable arm 2220 that can move away from or close to each other. The first movable arm 2210 and the second movable arm 2220 together form a clamping space for clamping the filter. Both clamping arms are made movable. By placing the filter on the free ends of the first movable arm 2210 and the second movable arm 2220 and pushing it towards the clamping space, the filter can be clamped between the two movable arms. Furthermore, in order to improve the stability of clamping, anti-slip pads 2230 are adhered to the inner walls of both the first movable arm 2210 and the second movable arm 2220.

[0038] Preferably, in this embodiment, to better assemble the filter clamp body 200 with the base 100 and improve the stability of the equipment during use, the connecting section 210 has an assembly portion 250 extending towards the base 100 on its assembly surface near the base 100, and the base 100 has a recessed portion 120 adapted to the assembly portion 250 on its assembly surface near the connecting section 210. During assembly, the assembly portion 250 is inserted into the recessed portion 120. Preferably, in this embodiment, a positioning protrusion 240 is provided on the assembly portion 250, and a positioning groove 110 adapted to the positioning protrusion 240 is provided on the recessed portion 120. The positioning structure of the positioning protrusion 240 and the positioning groove 110 completes the positional engagement of the base 100 and the filter clamp body 210.

[0039] The locking mechanism 300 is used to fix the base 100 and the filter clamp body 200. The locking mechanism 300 includes a locking connecting shaft 310 with one end connected to the mounting surface of the base 100, a locking member 320 disposed in the connecting section 210 to lock or disengage the locking connecting shaft 310, and an elastic member 330 that limits the locking member 320 to a first state or a second state. In this embodiment, the elastic member 330 is a spring. When the locking member 320 is in the first state, the locking member 320 is disengaged from the locking connecting shaft 310. When the locking member 320 is in the second state, the locking member 320 is locked to the locking connecting shaft 310. By controlling the movement of the locking member 320, the elastic member 330 is in a compressed or reset state, thereby controlling the locking or disengagement of the locking member 320 by the locking connecting shaft 310, improving the portability of installing and disassembling the filter clamp body 200 and the base 100.

[0040] Specifically, in this embodiment, the locking member 320 includes a pressing section 3210 and a movable section 3220 connected in sequence. One end of the movable section 3220 is provided with an insertion hole 3220-1 for inserting the locking connecting shaft 310. An arc-shaped limiting block 3230 is provided on the bottom outer wall of the insertion hole 3220-1. The front end outer wall of the locking connecting shaft 310 is recessed inward to form a limiting groove 3110 that matches the arc-shaped limiting block 3230. The connecting section 210 of the filter clamp body 200, near the base 100, is provided with an assembly hole 2130 that matches the locking connecting shaft 310 along the axial direction of the connecting section 210. The assembly hole 2130 is perpendicularly connected to the cavity 2110. The locking member 320 is located in the cavity 2110 and can move radially along the connecting section 210. The locking connecting shaft 310 passes through the assembly hole 2130 of the connecting section 210 and the insertion hole 3220-1 of the movable section 3220 in sequence and is located in the cavity 2110.

[0041] Preferably, in this embodiment, the bottom of the movable segment 3220 is provided with a first groove 3220-2 for limiting the spring, and the outer wall of the connecting segment 210 located on one side of the spring is provided with an end cap 230. The inner wall of the end cap 230 is provided with a second groove 2310 for limiting the spring. The first groove 3220-2 and the second groove 2310 together form a space to accommodate the spring, limiting the spring within the first groove 3220-2 and the second groove 2310, and preventing the spring from shifting during movement. During operation, when the pressing part 3210 drives the movable part 3220 to move synchronously towards the elastic member 330, the elastic member 330 is compressed under the pressure of the movable part 3220, and the arc-shaped limiting block 3230 disengages from the limiting groove 3110 on the locking connecting shaft 310. When the outer wall of the pressing section 3210 is flush with the outer wall of the connecting section 210, the filter clamp body 200 can be detached from the base 100. When the pressing part 3210 is released and the movable part 3220 moves synchronously away from the elastic member 330, the elastic member 330 returns to the stretched state, and the arc-shaped limiting block 3230 engages with the limiting groove 3110. Under the action of the elastic member 330, one end of the pressing section 3210 passes through the telescopic hole 2120 and is located outside the connecting section 210. At this time, the filter clamp body 200 and the base 100 are installed.

[0042] This utility model also includes a hemodialysis device, which includes a filter clip that is easy to disassemble and assemble. When the filter clip is damaged, it can be quickly disassembled for repair or replacement of parts. After the repair is completed, the assembly work can be carried out.

[0043] Combination Figures 1 to 8 The filter clip of this embodiment is easy to install and remove, and the specific usage process is as follows:

[0044] First, insert the base 100 into the equipment body on the side of the mounting ear 130 to fix the base 100 to the equipment;

[0045] 2. Press the pressing section 3210, which drives the movable section 3220 to move closer to the elastic element 300. The elastic element 300 is compressed, and the locking connecting shaft 310 is inserted into the assembly hole 2130 provided in the connecting section 210. The positioning structure of the positioning protrusion 240 and the positioning groove 110 completes the positional matching of the base 100 and the filter clamp body 210.

[0046] Third, releasing the pressing section 3210 causes the movable section 3220 to move away from the elastic element 300, resetting the elastic element 300. The arc-shaped limiting block 3230 engages with the limiting groove 3110 on the locking connecting shaft 310, completing the locking and fixing between the base 100 and the filter clamp body 210. When the pressing section 3210 is pressed again, the arc-shaped limiting block 3230 separates from the limiting groove 3110 on the locking connecting shaft 310, disengaging the base 100 from the filter clamp body 210.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
