Technical Field

[0001] The utility model relates to the technical field of CRRT blood filter auxiliary equipment, in particular to a CRRT blood filter fixing component. Background Art

[0002] Continuous renal renal therapy (CRRT) refers to a group of extracorporeal blood purification treatment technologies and is a general term for all treatment methods that continuously and slowly remove water and solutes. The blood purification filter is an essential component of a continuous blood purification therapy machine and is currently typically secured using a simple bracket and clamps. The most common clamping structures currently used are C-shaped grooves with curved clamps to clamp and secure the cylindrical blood filter. However, to prevent the blood filter from falling, this design often incorporates springs or bolts to tightly press the curved clamps against the blood filter, which can easily lead to damage due to excessive external pressure on the blood filter. Utility Model Content

[0003] The purpose of the present utility model is to provide a CRRT blood filter fixing assembly to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solutions: a CRRT blood filter fixing assembly, comprising a CRRT device and a blood filter, wherein a fixing mechanism is fixedly provided on the right outer wall of the CRRT device, and the blood filter is placed in the fixing mechanism;

[0005] The fixing mechanism includes a fixing plate, a bottom supporting plate, and a top pressure plate. The fixing plate and the bottom supporting plate are fixedly mounted on the right outer wall of the CRRT device. The top pressure plate is arranged above the fixing plate, and the bottom supporting plate is located below the fixing plate. A lifting component is arranged between the fixing plate and the top pressure plate. An S-shaped groove is provided on the top of the fixing plate. The blood filter is placed at the innermost side of the S-shaped groove. A limiting component is provided inside the S-shaped groove. The limiting component blocks the right side of the blood filter.

[0006] The limiting component includes a convex body, which is movably arranged in an S-shaped groove. An elastic airbag is fixedly installed on the front side of the convex body. The convex body and the elastic airbag form a semicircular plate. The back side of the convex body is rotatably connected to a threaded rod 2 through a bearing. The outer wall of the threaded rod 2 is threadedly connected to the inner wall of the fixed plate. A sliding rod 2 is fixedly installed on the back side of the convex body. The rear end of the sliding rod 2 movably passes through the inner wall of the S-shaped groove.

[0007] Furthermore, the lifting component includes a sliding rod and a threaded rod. The bottom end of the sliding rod is fixedly connected to the top of the fixed plate. The bottom end of the threaded rod is rotatably connected to the top of the fixed plate through a bearing. The outer wall of the threaded rod is threadedly connected to the inner wall of the top pressure plate. The top end of the sliding rod moves through the bottom of the top pressure plate.

[0008] Furthermore, the inner wall of the S-shaped groove and the outer wall of the elastic airbag are both provided with smooth rubber pads.

[0009] Furthermore, the bottom supporting plate and the top pressure plate are both provided with avoidance grooves, and the pipes at the top and bottom ends of the blood filter pass through the avoidance grooves.

[0010] Furthermore, a limit seat is fixedly installed on the top of the bottom supporting plate, the limit seat is sleeved on the bottom end of the blood filter, and a notch corresponding to the limit seat is opened on the limit seat.

[0011] Furthermore, a protective shell is fixedly installed on the right outer wall of the CRRT device, and the protective shell covers the left end of the fixed plate, the bottom support plate, and the top pressure plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. An S-shaped groove is provided for placing and limiting the blood filter. Since the blood filter does not act as a force-bearing member, the S-shaped groove is used to limit the blood filter and prevent it from falling off. This placement method is not only convenient, but also prevents the blood filter from being damaged by the force exerted by the force-applying member on the blood filter. A top pressure plate is provided to limit the upper part of the blood filter to prevent the blood filter from popping up, and a limiting component is provided to limit the blood filter.

[0014] 2. Because the convex body and elastic airbag in the limiting component only serve as blocking members to block the blood filter, there is no need to apply force on the blood filter. When taking out and placing the blood filter, the soft and easily deformable elastic airbag can be squeezed to allow the blood filter to pass through the limiting component. The position of the convex body can be adjusted by rotating the second threaded rod to match a blood filter that is not too thick. The top pressure plate can be raised and lowered by the lifting component to match a blood filter that is not too long. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1-4 The utility model provides a technical solution: a CRRT blood filter fixing assembly, comprising a CRRT device 1 and a blood filter 2. A fixing mechanism 3 is fixedly provided on the right outer wall of the CRRT device 1, and the blood filter 2 is placed in the fixing mechanism 3;

[0022] The fixing mechanism 3 includes a fixing plate 301, a bottom supporting plate 303, and a top pressure plate 304. The fixing plate 301 and the bottom supporting plate 303 are fixedly mounted on the right outer wall of the CRRT device 1. The top pressure plate 304 is arranged above the fixing plate 301, and the bottom supporting plate 303 is located below the fixing plate 301. A lifting component 305 is provided between the fixing plate 301 and the top pressure plate 304. An S-shaped groove 302 is provided at the top of the fixing plate 301. The blood filter 2 is placed at the innermost part of the S-shaped groove 302. A limiting component 306 is provided inside the S-shaped groove 302, blocking the right side of the blood filter 2.

[0023] The limiting component 306 includes a convex body 3061, which is movably arranged in the S-shaped groove 302. An elastic airbag 3064 is fixedly installed on the front of the convex body 3061. The convex body 3061 and the elastic airbag 3064 form a semicircular plate. The back of the convex body 3061 is rotatably connected to the second threaded rod 3062 through a bearing. The outer wall of the second threaded rod 3062 is threadedly connected to the inner wall of the fixed plate 301. The back of the convex body 3061 is fixedly installed with the second sliding rod 3063. The rear end of the second sliding rod 3063 movably passes through the inner wall of the S-shaped groove 302. A bottom supporting plate 303 is provided for supporting the blood filter 2, and an S-shaped groove 302 is provided for placing and limiting the blood filter 2. Because the blood filter 2 does not serve as a force-bearing member, the S-shaped groove is used to limit the blood filter 2, which can prevent the blood filter 2 from falling off. The placement method is not only convenient for placement, but also prevents the blood filter 2 from being damaged due to the force exerted by the force-applying member on the blood filter 2. A top pressure plate 304 is provided to limit the upper portion of the blood filter 2 to prevent the blood filter 2 from popping up. A limiting component 306 is provided to limit the blood filter 2 because the convex body 3061 and the elastic airbag 3064 in the limiting component 306 only serve as blocking members to block the blood filter 2, and there is no need to apply force on the blood filter 2. When the blood filter 2 is taken in or out, the soft and easily deformable elastic airbag 3064 can be squeezed to allow the blood filter 2 to pass through the limiting component 306. The position of the convex body 3061 is adjusted by rotating the threaded rod 3062 to match a blood filter 2 of not too thick or too thin. The top pressure plate 304 is raised and lowered by the lifting component 305 to match a blood filter 2 of not too long.

[0024] The lifting component 305 includes a sliding rod 3051 and a threaded rod 3052. The bottom end of the sliding rod 3051 is fixedly connected to the top of the fixed plate 301. The bottom end of the threaded rod 3052 is rotatably connected to the top of the fixed plate 301 via a bearing. The outer wall of the threaded rod 3052 is threadedly connected to the inner wall of the top pressure plate 304. The top end of the sliding rod 3051 movably penetrates the bottom of the top pressure plate 304. By rotating the threaded rod 3052, the top pressure plate 304 is moved up and down, thereby adjusting the distance between the top pressure plate 304 and the fixed plate 301 to match blood filters 2 of different lengths.

[0025] The inner wall of the S-shaped groove 302 and the outer wall of the elastic airbag 3064 are both provided with smooth rubber pads 5, which form a buffer between the inner wall of the S-shaped groove 302 and the outer wall of the blood filter 2;

[0026] The bottom support plate 303 and the top pressure plate 304 are both provided with avoidance grooves 7. The pipes at the top and bottom of the blood filter 2 pass through the avoidance grooves 7 to ensure that the pipes above the blood filter 2 will not get stuck when the blood filter 2 is placed in the S-shaped groove 302.

[0027] A limit seat 6 is fixedly mounted on the top of the bottom support plate 303. The limit seat 6 is sleeved on the bottom end of the blood filter 2. A notch is formed on the limit seat 6 corresponding to the notch. The limit seat 6 is provided to limit the bottom end of the blood filter 2, further preventing the blood filter 2 from tilting.

[0028] A protective shell 4 is fixedly installed on the right outer wall of the CRRT device 1. The protective shell 4 covers the left end of the fixed plate 301, the bottom support plate 303, and the top pressure plate 304. The top of the protective shell 4 is provided with a notch corresponding to the slide rod 3051 and the threaded rod 3052. The protective shell 4 is provided to form a layer of protection to reduce the probability of external objects colliding with the blood filter 2.

[0029] Working principle: When the blood filter 2 needs to be placed, it is placed from the rightmost end of the S-shaped groove 302 so that the blood filter 2 enters the innermost side of the S-shaped groove 302. When the blood filter 2 passes through the limiting component 306, the elastic airbag 3064 can be squeezed, causing the elastic airbag 3064 to deform, allowing the blood filter 2 to pass through the gap between the limiting component 306 and the S-shaped groove 302.

[0030] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
