Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a filter clip and a blood purification device. Background Art

[0002] Blood purification equipment is a medical device used to remove certain pathogenic substances such as waste, toxins and excess fluid from the patient's blood to maintain the body's internal environment balance such as electrolyte balance and acid-base balance to purify blood and treat diseases. It has been widely used in various medium and large hospitals, blood purification centers and other medical places. Among them, the physical safety of blood purification equipment has an important impact on the safety of blood purification treatment for patients.

[0003] Blood purification equipment usually needs to be equipped with a filter device on the main body to filter and purify the blood drawn out of the patient's body, and then return the blood purified by the filter device to the patient's body. In addition, blood purification equipment generally includes a variety of blood purification treatment modes such as hemodialysis mode, hemofiltration mode, hemoperfusion mode, plasma exchange mode, and immunoadsorption mode. Each blood purification treatment mode is generally used to treat specific clinical symptoms. For example, the hemodialysis mode is mainly used for the treatment of diseases such as acute and chronic renal failure, and the hemoperfusion mode is mainly used for the treatment of various critical diseases such as drug poisoning, poison poisoning, and sepsis. Among them, for different blood purification treatment modes, users can choose the corresponding type of filter device according to clinical treatment needs. For example, in the hemodialysis mode, a filter device including a hemodialyzer is generally selected; in the hemoperfusion mode, a filter device including a hemoperfusion device is generally selected.

[0004] Existing blood purification equipment usually also has a filter clamp on the main body to clamp the filter device and conveniently control the placement of the filter device. Therefore, the mechanical properties of the filter clamp play an important role in the clamping safety and stability of the filter device, and also have an important impact on the safety of blood purification treatment. However, the various operations of the existing filter clamp when clamping the filter device are inconvenient, and the safety and stability are not high. For example, it is difficult or even impossible to adjust the height of the filter device, and it is impossible to ensure that the filter device can be driven to rotate safely and stably, etc., which makes it difficult to meet the actual needs of clinical treatment of the filter device and reduces the safety of the patient's blood purification treatment. Utility Model Content

[0005] The purpose of the embodiments of the utility model is to solve the technical problems that the existing filter clamps are inconvenient to operate when clamping the filter device, have low safety and stability, and are difficult to meet the actual needs of clinical treatment.

[0006] In order to solve the above technical problems, the embodiment of the utility model provides a filter clamp, which adopts the following technical solution:

[0007] The filter holder comprises:

[0008] A mounting seat connected to the external body;

[0009] A clamping device, comprising a first clamping member and a second clamping member, wherein the first clamping member and the second clamping member jointly enclose a clamping space of independently adjustable size and are used to jointly clamp a target object in the clamping space;

[0010] An intermediate connecting device, comprising a connecting arm, wherein the connecting arm is located between the mounting seat and the clamping device;

[0011] Among them, one end of the connecting arm is connected to the clamping device in a damping rotation manner so that the clamping device can rotate circumferentially relative to the connecting arm; and / or the intermediate connecting device also includes a pitch rotation assembly, and the other end of the connecting arm is connected to the mounting seat in a damping rotation manner through the pitch rotation assembly so that the clamping device and the connecting arm can perform pitch motion relative to the mounting seat.

[0012] Compared with the prior art, the filter clip and blood purification device provided by the embodiment of the utility model mainly have the following beneficial effects:

[0013] The filter clamp makes the clamping space of the clamping device adjustable and independent of the rotation of the clamping device, so that the clamping device can not only clamp the target part stably, firmly and safely, but also can conveniently rotate circumferentially to any angle together with the target part; and / or, the connecting arm is connected to the mounting seat by damping rotation through a pitch rotation assembly, so that the clamping device and the target part can be adjusted and maintained at any height within the adjustable height range. That is, the filter clamp can not only ensure that the filter device and other target parts are safely, firmly and stably installed on the blood purification equipment through the clamping device, but can also rotate 360 ​​degrees at a fixed point with the clamping device, and / or be adjusted to any height at a fixed point within the adjustable range, so as to meet the needs of the filter device and other target parts for blood purification treatment of patients at any height.

[0014] In short, the filter clamp has multiple functions, reduces the difficulty of installing and clamping the filter device, facilitates adjusting the filter device and other target parts to the appropriate position, can meet actual clinical treatment needs, and is conducive to the safe and effective treatment of the patient's blood.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0045] The embodiment of the utility model provides a filter clamp 100, which can be used to clamp a filter device (not shown), and can also be used to clamp other objects, that is, the target part (not shown) clamped by the filter clamp 100 includes but is not limited to the filter device. Similarly, the filter device here includes but is not limited to a hemodialyzer and a hemoperfusion device. In addition, the filter clamp 100 can be applied to a blood purification device 1000, and can also be applied to other devices, without special restrictions. For the convenience of explanation, the following will be described by taking the filter clamp 100 used to clamp a filter device in a blood purification device 1000 as an example.

[0046] like Figures 1 to 3 As shown, the filter clamp 100 includes a mounting seat 1, a clamping device 2 and an intermediate connecting device 3, wherein the mounting seat 1 is connected to the external main body 200. In practical applications, the filter clamp 100 will be set on the main body 200 of the blood purification device 1000 at any angle. Exemplarily, one end of the mounting seat 1 can be detachably connected to the main body 200 of the blood purification device 1000, and the other end is connected to the other end of the intermediate connecting device 3, so that the entire filter clamp 100 is fixedly mounted on the main body 200 of the blood purification device 1000 through the mounting seat 1, and the specific installation angle of the mounting seat 1 and the installation position in the blood purification device 1000 can be determined according to actual needs.

[0047] Further illustratively, if Figure 1 and Figure 4 As shown, a first threaded hole is provided at one end of the mounting base 1, and a corresponding second threaded hole (not shown) is also provided on the main body 200 of the blood purification device 1000. One end of the mounting base 1 can be detachably connected to the main body 200 of the blood purification device 1000 through the threaded cooperation of the first threaded hole, the second threaded hole and screws, screws, bolts and other screw parts (not shown).

[0048] Of course, the mounting base 1 and the main body 200 of the blood purification device 1000 can be detachably connected together by means of snap connection, plug connection, rotational locking connection, etc., and can also be fixedly connected together by riveting, bonding, etc., depending on actual needs.

[0049] like Figures 1 to 3 As shown, in order to achieve the clamping of a target part including but not limited to a filter device, the target part is installed on the main body 200 of the blood purification device 1000 through the filter clamp 100, and the clamping device 2 includes a first clamping part 21 and a second clamping part 22, wherein the first clamping part 21 and the second clamping part 22 together form a clamping space 23 of adjustable size, and the first clamping part 21 and the second clamping part 22 are used to jointly clamp the target part in the clamping space 23.

[0050] Exemplarily, the first clamping member 21 and the second clamping member 22 are arranged opposite to each other, and there is a closed state and an open state between the two. Figure 1 As shown, in the initial state, that is, the state where the target part is not clamped, the ends of the first clamping member 21 and the second clamping member 22 away from the mounting seat 1 can freely abut against each other. In the open state, the ends of the first clamping member 21 and the second clamping member 22 away from the mounting seat 1 will move away from each other to form an opening (not shown). It should be noted that the size of the opening will be different depending on the size of the target part to be clamped.

[0051] Of course, in other examples, the first clamping member 21 and the second clamping member 22 may be kept open, and it is only necessary to ensure that the size of the opening can be adaptively adjusted according to the size of the target object so that the size of the clamping space 23 is obtained. In addition, it should be noted that when the clamping space 23 is adaptively adjusted, at least one of the first clamping member 21 and the second clamping member 22 can be adjusted, and the specific adjustment can be made according to the actual situation.

[0052] It can be understood that, in the open state, when target parts of different sizes are fully or partially accommodated in the clamping space 23, after releasing the first clamping member 21 and / or the second clamping member 22, the first clamping member 21 and the second clamping member 22 can be adaptively adjusted to form a clamping space 23 of a size matching the specific size of the target part. In short, the size of the clamping space 23 is adapted to the size of the target part, so that the clamping force of the first clamping member 21 and the second clamping member 22 on different target parts can be adjusted, so as to maintain the corresponding appropriate clamping force, that is, it can firmly clamp the target part such as the filter device without clamping the target part too tightly, so as to ensure the physical safety of the clamping of the target part such as the filter device.

[0053] like Figures 1 to 3 As shown, the intermediate connecting device 3 includes a connecting arm 31, wherein the connecting arm 31 is located between the mounting seat 1 and the clamping device 2, and one end of the connecting arm 31 is connected to the clamping device 2 for damping rotation so that the clamping device 2 can rotate circumferentially relative to the connecting arm 31, and the other end of the connecting arm 31 is connected to the mounting seat 1.

[0054] It should be particularly noted that the damping rotation connection function between the connecting arm 31 and the clamping device 2 and the adjustable size function of the clamping space 23 of the clamping device 2 are independent of each other. In other words, the clamping device 2 can independently adjust the size of the clamping space 23, and the size of the clamping space 23 can be adjusted without the interaction between the connecting arm 31 and the clamping device 2.

[0055] Understandably, on the one hand, through the damping rotation connection between the connecting arm 31 and the clamping device 2, the clamping device 2 can rotate 360 ​​degrees around the connecting arm 31 together with the target part, and stay at the target position at any time, that is, the filter device and other target parts can be easily rotated to any angle, which is convenient for meeting clinical needs. On the other hand, because the rotation operation and the clamping operation of the clamping device 2 are independent of each other, compared with the structure in which the clamping operation and the rotation operation of the clamping device 2 are linked to each other, the filter clamp 100 can ensure that the clamping device 2 can still stably, firmly and safely clamp the target part when the clamping device 2 drives the filter device and other target parts to rotate together.

[0056] and / or, if Figures 1 to 3 As shown, the intermediate connecting device 3 also includes a pitch rotation assembly 32, and the other end of the connecting arm 31 is connected to the mounting base 1 through the pitch rotation assembly 32, so that the clamping device 2 and the connecting arm 31 can make a pitch movement relative to the mounting base 1, so as to realize any height adjustment of the clamping device 2 within the adjustable height range, and the target part such as the filter device can be kept at the target height through the clamping device 2.

[0057] It should be noted that one end of the connecting arm 31 can be directly fixedly connected or detachably connected to the clamping device 2, or can be connected to the clamping device 2 in a damped rotation manner. It can be understood that in the present application, the filter clamp 100 has at least the following three structural forms:

[0058] In the first structural form, the size of the clamping space 23 of the clamping device 2 is independently adjustable so as to be adapted to clamp target parts of different sizes; and one end of the connecting arm 31 is connected to the clamping device 2 with damping rotation so as to be able to rotate around the connecting arm 31 to any angle together with the clamped target part, and the other end of the connecting arm 31 is directly fixedly connected or detachably connected to the mounting seat 1. That is, in this structural form, the filter clamp 100 has two functions: the clamping space 23 is adjustable and can rotate at any angle.

[0059] In the second structural form, the size of the clamping space 23 of the clamping device 2 is independently adjustable so as to adapt to clamping target parts of different sizes; one end of the connecting arm 31 is directly fixedly connected or detachably connected to the clamping device 2, and the other end is connected to the mounting seat 1 through the pitch rotation assembly 32 to achieve arbitrary height adjustment of the clamping device 2 and the clamped target part within the adjustable height range. That is, in this structural form, the filter clamp 100 has two functions: adjustable clamping space 23 and arbitrary height adjustment within the allowable range.

[0060] In the third structural form, the size of the clamping space 23 of the clamping device 2 is independently adjustable so as to adapt to clamping target parts of different sizes; one end of the connecting arm 31 is connected to the clamping device 2 with damping rotation so as to be able to rotate around the connecting arm 31 to any angle together with the clamped target part; the other end of the connecting arm 31 is connected to the mounting seat 1 with damping rotation through the pitch rotation assembly 32, so as to achieve any height adjustment of the clamping device 2 and the clamped target part within the height adjustable range. That is, in this structural form, the filter clamp 100 has three functions: adjustable clamping space 23, rotation at any angle, and any height adjustment within the allowable range.

[0061] The specific structural form of the filter clamp 100 can be determined according to actual needs.

[0062] In summary, compared with the prior art, the filter clamp 100 has at least the following beneficial effects: the filter clamp 100 has multiple functions, reduces the difficulty of installing and clamping the filter device, facilitates adjusting the filter device and other target parts to a suitable position, can meet actual clinical treatment needs, and facilitates safe and effective treatment of the patient's blood.

[0063] Specifically, the filter clamp 100 makes the clamping space 23 of the clamping device 2 adjustable and independent of the rotation of the clamping device 2, so that the clamping device 2 can not only stably, firmly and safely clamp the target part, but also can conveniently rotate circumferentially to any angle together with the target part; and / or, the connecting arm 31 is connected to the mounting seat 1 by damping rotation through the pitch rotation component 32, so that the clamping device 2 and the target part can be adjusted and maintained at any height within the adjustable height range. That is, the filter clamp 100 can not only ensure that the target part such as the filter device is safely, firmly and stably installed on the blood purification equipment 1000 through the clamping device 2, but also can be rotated 360 degrees at a fixed point with the clamping device 2, and / or can be adjusted to any height at a fixed point within the adjustable range, so as to meet the blood purification treatment needs of the target part such as the filter device at any height.

[0064] Embodiment 1 of the filter clip 100 of the present invention

[0065] In order to make the technical personnel in this field better understand the present utility model scheme, the following will be combined with the attached Figures 1 to 24 , clearly and completely describe the technical solution in Example 1 of the utility model.

[0066] In some specific implementations of the first embodiment of the present utility model, as Figures 4 to 7 As shown, in order to realize the damping rotation connection between the pitch rotation component 32 and the connecting arm 31 and the mounting seat 1, the pitch rotation component 32 includes a first connecting shaft 321 and a first damping structure, and the first damping structure includes a first damping component 322 and a first elastic member 323, wherein the first connecting shaft 321 is passed through the other end of the connecting arm 31 and the mounting seat 1, so that the connecting arm 31 and the mounting seat 1 can rotate relative to each other around the first connecting shaft 321, so as to realize the pitch movement of the connecting arm 31 and the clamping device 2, that is, to make a nodding action relative to the mounting seat 1.

[0067] Exemplarily, in order to achieve pitch movement of the connecting arm 31 and the clamping device 2 relative to the mounting base 1, the first connecting axis 321 can be set along a length direction perpendicular to the connecting arm 31. For example, if the connecting arm 31 is set longitudinally, the first connecting axis 321 is set horizontally.

[0068] In addition, the first damping component 322 can be used to damp the rotation of the connecting arm 31 relative to the mounting base 1 around the first connecting axis 321. In practical applications, the specific structure of the first damping component 322 can adopt an existing damping structure or a newly created damping structure, which is not particularly limited here, as long as it can damp the relative pitch rotation of the connecting arm 31 and the mounting base 1.

[0069] like Figures 6 to 8As shown, the first elastic member 323 is sleeved on the first connecting shaft 321 to buffer the damping rotation of the connecting arm 31 by means of compression and expansion. It can be understood that when the connecting arm 31 makes a pitching motion relative to the mounting seat 1, the first damping assembly 322 can damp the rotation of the connecting arm 31, and while the first damping assembly 322 performs the damping effect, the first elastic member 323 will be squeezed along the axial direction of the first connecting shaft 321 to generate an elastic expansion force, which can buffer and damp the rotation process of the connecting arm 31, so that the user can more smoothly and stably adjust the target part such as the filter device clamped by the clamping device 2 to any suitable height without using much effort.

[0070] It should be noted that, during the relative rotation of the connecting arm 31 and the mounting seat 1, the mounting seat 1 remains stationary, and the connecting arm 31 and the first connecting shaft 321 rotate relative to the mounting seat 1, or the mounting seat 1 and the first connecting shaft 321 remain stationary, and the connecting arm 31 rotates relative to the mounting seat 1 and the first connecting shaft 321. Take the example of the connecting arm 31 and the first connecting shaft 321 rotating relative to the mounting seat 1 together:

[0071] like Figure 3 and Figure 5 As shown, in some specific implementations of the first embodiment, the mounting seat 1 includes a seat body 11 and a connecting portion 12, and the connecting arm 31 includes an arm body 311 and two rotating seats 312, wherein the two rotating seats 312 are connected to the arm body 311 and are arranged side by side in the axial direction of the first connecting shaft 321. The connecting portion 12 of the mounting seat 1 is inserted into the gap 313 between the two rotating seats 312, and the first connecting shaft 321 is inserted into the connecting portion 12 and the two rotating seats 312. Specifically, the middle part of the first connecting shaft 321 axially passes through the connecting portion 12 of the mounting seat 1, and the two ends of the first connecting shaft 321 are respectively fixedly installed on the two rotating seats 312, so that the first connecting shaft 321 and the two rotating seats 312 are connected and fixed together, so that the first connecting shaft 321, the connecting arm 31, the clamping device 2 and the target part are pitched and rotated relative to the mounting seat 1, so as to adjust the height of the target part.

[0072] like Figure 7 and Figure 8As shown, the first damping assembly 322 includes a first concave-convex structure 3221 and a first plug-in 3222, wherein the first concave-convex structure 3221 has a plurality of first grooves 32211 arranged circumferentially, and the first concave-convex structure 3221 is disposed on the connection portion 12 of the mounting seat 1, specifically, the first concave-convex structure 3221 can be directly formed on the connection portion 12, and can also be indirectly disposed on the connection portion 12. The first plug-in 3222 is radially plugged into the first connecting shaft 321, so that when the connecting arm 31 and the first connecting shaft 321 rotate relative to the mounting seat 1, the first concave-convex structure 3221 can rotate relative to the first concave-convex structure 3221, and can be concave-convexly matched with the corresponding first groove 32211.

[0073] It can be understood that the first plug-in 3222 is fixedly mounted on the first connecting shaft 321, so that when the connecting arm 31 and the first connecting shaft 321 rotate relative to the mounting base 1, the first plug-in 3222 can also rotate with the first connecting shaft 321, and the first plug-in 3222 can be stuck in the first groove 32211 or detached from the first groove 32211 during the rotation. If the first plug-in 3222 fits into the first groove 32211, the pitch rotation of the connecting arm 31 and the clamping device 2 will be stuck or paused, so as to realize the fixed-point height adjustment of the target parts such as the filter device.

[0074] For example, in order to fix the first plug-in 3222 on the first connecting shaft 321, the first connecting shaft 321 is provided with a first mounting hole 3212 in the radial direction (see Fig.13 ),like Figure 8 and Fig.12 As shown, the first plug-in unit 3222 is plugged into the first mounting hole 3212 to be fixedly mounted on the first connecting shaft 321 .

[0075] like Figure 7 and Figure 8 As shown, the outer wall of the first connecting shaft 321 is convexly provided with a limiting rib 3211, and the first elastic member 323 is located between the limiting rib 3211 and the first concave-convex structure 3221, so as to be axially squeezed by the limiting rib 3211 when the first plug-in 3222 is separated from the corresponding first groove 32211. It can be understood that when the connecting arm 31, the first connecting shaft 321 and the first plug-in 3222 rotate relative to the mounting seat 1, the first connecting shaft 321 will have a slight axial movement during the process of the first plug-in 3222 being separated from the corresponding first groove 32211. When the first connecting shaft 321 moves axially, the limiting rib 3211 arranged on the first connecting shaft 321 can axially squeeze the first elastic member 323 to generate an elastic telescopic force.

[0076] Among them, the elastic telescopic force can, on the one hand, enable the first connecting shaft 321 to quickly return to its original position, so as to ensure that the first plug-in 3222 quickly returns to cooperate with the corresponding first groove 32211, thereby ensuring that the height adjustment of the target part such as the filter device clamped by the clamping device 2 is safer and more reliable; on the other hand, it can buffer the damping rotation between the connecting arm 31 and the mounting seat 1, so that the fixed-point height adjustment of the target part can be achieved more smoothly and conveniently without too much effort.

[0077] Exemplarily, when the connecting arm 31 and the first connecting shaft 321 rotate together relative to the mounting base 1, in order to achieve stable and smooth pitching motion of the clamping device 2 and the connecting arm 31 through the first damping structure, the cooperation between the first damping component 322 and the first elastic member 323 has at least the following two specific implementations:

[0078] In a first specific embodiment (not shown), the first concavo-convex structure (not shown) is directly formed on the connecting portion 12. Specifically, the first concavo-convex structure is provided on one end of the connecting portion 12 of the mounting seat 1 close to the first plug-in 3222. For example, a plurality of first grooves arranged circumferentially are provided on one end of the connecting portion 12 of the mounting seat 1 close to the first plug-in 3222. In addition, the first elastic member 323 is limited to the connecting portion 12 and the limiting rib 3211.

[0079] When the first plug-in is disengaged from the first groove, the first plug-in will drive the first connecting shaft 321 to move slightly away from the first groove, so that the limiting rib 3211 will move toward the connecting part 12 to axially squeeze the first elastic member 323, so that the disengagement action of the first plug-in becomes gentle. During the continued rotation of the first plug-in, the first connecting shaft 321, the connecting arm 31 and the clamping device 2, under the action of the rebound force of the first elastic member 323, the first plug-in will slowly move closer to the connecting part 12, so that it can finally cooperate with another first groove of the first concave-convex structure 1, and the rotation cycle will be repeated to smoothly and conveniently realize the fixed-point height adjustment of the target part.

[0080] Alternatively, in a second specific implementation, the first concave-convex structure 3221 is indirectly disposed on the connecting portion 12. For example, Figure 7 , Figure 8 and Fig.12 As shown, the first damping assembly 322 further includes a first rotating shaft 3223, and the connecting portion 12 of the mounting seat 1 is axially provided with a first plug hole 121 (see Fig.14), a first concave-convex structure 3221 is provided at one end of the first rotating shaft 3223 close to the first plug-in 3222, and the first rotating shaft 3223 is sleeved on the first connecting shaft 321 and installed on the first plug hole 121. In addition, the first elastic member 323 is limited to the first rotating shaft 3223 and the limiting rib 3211, or the first elastic member 323 is limited to the connecting portion 12 and the limiting rib 3211.

[0081] Further exemplary, the first rotating shaft 3223 is installed in the connecting portion 12 of the mounting seat 1, such as Figure 7 , Fig. 9 , Fig.12 and Fig.14 As shown, the connecting portion 12 of the mounting base 1 is also provided with a second mounting hole 122 (see Fig.14 ), the second mounting hole 122 is communicated with the first insertion hole 121, the first rotating shaft 3223 is located in the first insertion hole 121, and the first rotating shaft 3223 is threadedly connected with the second mounting hole 122 and the first rotating shaft 3223 through the first fastener 123 to be installed in the connecting portion 12 of the mounting seat 1.

[0082] Similarly, in the initial state or when the first plug 3222 is in concave-convex cooperation with the first groove 32211, the end of the limiting rib 3211 away from the connecting portion 12 can be close to the corresponding rotating seat 312, and the two ends of the first elastic member 323 are respectively in contact with the limiting rib 3211 and the first rotating shaft 3223 or the connecting portion 12. When the first plug 3222 is separated from the first groove 32211, the first plug 3222 will drive the first connecting shaft 321 to move slightly away from the first groove 32211, so that the limiting rib 3211 will move towards the connecting portion 12 to axially squeeze the first elastic member 323, so that the first plug 3222 The disengagement action of 22 becomes gentle, and during the continued rotation of the first plug-in 3222, the first connecting shaft 321, the connecting arm 31 and the clamping device 2, under the action of the rebound force of the first elastic member 323, the first plug-in 3222 will instantly move closer to the connecting portion 12, and can cooperate with the next adjacent first groove 32211 in the first concave-convex structure 3221 to produce a jam, and with the continuous rotation of the first plug-in 3222, this jam will continue to occur intermittently, so that the operator can receive feedback on the rotation operation, which is more convenient for adjusting the height of the target part, and facilitates smoother and more convenient implementation of fixed-point height adjustment of the target part.

[0083] In some specific implementations of this embodiment 1, Figures 4 to 8 As shown, in order to facilitate the manufacture and installation of the rotating seat 312 in the connecting arm 31, each rotating seat 312 includes a rotating seat 3121 and a rotating wheel 3122, wherein the two rotating seats 3121 are arranged on the arm body 311 along the axial gap 313 of the first connecting shaft 321. Fig.15 and Fig.16As shown, the two swivel seats 3121 are integrally formed with the arm body 311 of the connecting arm 31 to form one part, so as to simplify the overall structure and facilitate quick installation.

[0084] For example Figures 4 to 8 As shown, the two rotating wheels 3122 are respectively inserted into the two ends of the first connecting shaft 321, and are detachably connected to the corresponding rotating seats 3121, so as to be assembled into two rotating seats 312 at the two ends of the first connecting shaft 321, so that the first connecting shaft 321 and the two rotating seats 312 rotate together along the central axis of the first connecting shaft 321 relative to the mounting seat 1.

[0085] For example, Fig.11 and Fig.12 As shown, the two wheels 3122 are provided with blind holes (not shown) in their axial direction, and the opposite ends of the first connecting shaft 321 are respectively inserted into the blind holes (not shown) corresponding to the two wheels 3122, so that the first connecting shaft 321 is fixedly connected to the two wheels 3122. Fig.13 As shown, the cross-sections of the opposite ends of the first connecting shaft 321 are non-circular surfaces to ensure that the first connecting shaft 321 and the two rotating wheels 3122 rotate together. Figure 4 , Fig.15 and Fig.16 As shown, each rotating seat 3121 is provided with a third mounting hole 31211, correspondingly, as shown in FIG. Figure 4 As shown, each rotating wheel 3122 is provided with a fourth mounting hole 31221 , and the rotating seat 3121 is threadedly connected to the third mounting hole 31211 and the fourth mounting hole 31221 in sequence through a second fastener 3123 , so as to be fixedly connected with the rotating wheel 3122 to form the above-mentioned rotating seat 312 .

[0086] Understandably, the two ends of the first connecting shaft 321 can be respectively inserted into the blind holes of the two rotating wheels 3122, and then the first connecting shaft 321 with the two rotating wheels 3122 can be inserted into the gap 313 between the two rotating seats 3121 along the length direction of the connecting arm 31, and the two rotating wheels 3122 can be respectively corresponding to the two rotating seats 3121, and finally each rotating seat 3121 and the corresponding rotating wheel 3122 can be threaded together through the second fastener 3123, so as to realize the rotation of the first connecting shaft 321, the connecting arm 31 with the two rotating seats 312 and the clamping device 2 around the central axis of the first connecting shaft 321 relative to the mounting seat 1. On the whole, the structure is simple and compact, and it is convenient for disassembly, assembly and manufacturing.

[0087] In some specific implementations of this embodiment 1, Figures 5 to 8 As shown, the connecting arm 31 includes a sleeve, a rotating connecting member 314 and a second damping structure, wherein Figure 2 , Figure 5 and Fig.15As shown, a rotating hole 3111 is axially opened at one end of the sleeve (the end away from the mounting seat 1); one end of the rotating connecting piece 314 is fixedly connected to the clamping device 2, and the other end is rotatably inserted into the rotating hole 3111, so that the rotating connecting piece 314 drives the clamping device 2 to rotate 360 ​​degrees relative to the sleeve around the central axis of the rotating connecting piece 314, and is independent of the clamping action of the clamping device 2, and the rotating connecting piece 314 is circumferentially limited by the rotating hole 3111 to ensure the stability and smoothness of the rotation.

[0088] It should be noted that, when the connecting arm 31 and the clamping device 2 can perform pitch motion relative to the mounting base 1, the sleeve of the connecting arm 31 is the arm body 311 of the connecting arm 31. Figure 8 As shown, to ensure that the sleeve of the connecting arm 31 can rotate relative to the mounting base 1 around the first connecting axis 321 together with the rotating base 312, the other end of the rotating connecting member 314 is spaced from the connecting portion 12 of the mounting base 1 to avoid interference between the rotating connecting member 314 and the connecting portion 12.

[0089] like Figure 4 , Figures 6 to 8 As shown, the second damping structure includes a second damping component 315, a stopper 316 and a second elastic component 317, wherein the second damping component 315 can be used to damp the circumferential rotation of the clamping device 2 and the rotating connection member 314 relative to the sleeve. In practical applications, the specific structure of the second damping component 315 can adopt an existing damping structure or a newly created damping structure, which is not particularly limited here, and only needs to be able to damp the circumferential rotation of the rotating connection member 314 and the clamping device 2.

[0090] like Figure 2 , Figure 6 and Figure 8 As shown, the stopper 316 is disposed on the rotating connection member 314, and the second elastic member 317 is sleeved on the rotating connection member 314 in the rotating hole 3111, so as to buffer the damping rotation of the rotating connection member 314 and the clamping device 2 through the extrusion of the stopper 316. It can be understood that when the operator manually rotates the clamping device 2 holding the target part such as the filter device, so that the rotating connection member 314 and the clamping device 2 rotate circumferentially relative to the sleeve, the second damping component 315 can play a damping role in the circumferential rotation of the rotating connection member 314, so that the rotating connection member 314 and the clamping device 2 can rotate 360 ​​degrees at a fixed point, and while the second damping component 315 implements the damping effect, the second elastic member 317 will be squeezed by the stopper 316 along the axial direction of the rotating connection member 314 to generate an elastic expansion force.

[0091] This elastic telescopic force can buffer and damp the circumferential rotation of the rotating connector 314 and the clamping device 2, so that the operator does not need to use a lot of force. On the one hand, it reduces the strong impact and friction between the components, ensures physical safety, and helps to increase the service life of the filter clamp 100; on the other hand, it can more smoothly, stably and conveniently rotate the target parts such as the filter device clamped by the clamping device 2 to any target angle, so that the filter device can perform blood purification operations at any angle.

[0092] In some specific implementations of this embodiment 1, Figure 4 , Figures 6 to 8 , Fig.17 As shown, in order to realize the damping effect of the second damping assembly 315, the second damping assembly 315 includes a second rotating shaft 3151 and a second plug-in unit 3153, wherein the second rotating shaft 3151 is sleeved on the rotating connecting member 314 and fixedly mounted on the rotating hole 3111 of the sleeve.

[0093] For example, the second rotating shaft 3151 is axially provided with an axial hole 31511 (see Fig.19 ), the rotating connecting member 314 is inserted into the shaft hole 31511 of the second rotating shaft 3151 along the length direction of the sleeve, so that the second rotating shaft 3151 is sleeved on the rotating connecting member 314. In addition, the sleeve is radially provided with a fifth mounting hole 3112 (see Fig.16 ), correspondingly, the second rotating shaft 3151 is provided with a sixth mounting hole 31512 in radial direction thereof which is in communication with the shaft hole 31511 (see Fig.19 and Fig. 20 ), wherein the second rotating shaft 3151 is threadedly connected to the fifth mounting hole 3112 and the rotating hole 3111 in sequence through the third fastener 3154 and the sixth mounting hole 31512 to be fixedly installed in the rotating hole 3111 of the sleeve.

[0094] It should be noted that the sixth mounting hole 31512 is a threaded hole, and the fifth mounting hole 3112 can be a threaded through hole or a light through hole. The third fastener 3154 can be a threaded member with external threads such as a screw or a bolt.

[0095] like Figure 6 , Figure 8 and Fig.17 As shown, a second concave-convex structure 3152 is disposed at one end of the second rotating shaft 3151. The second concave-convex structure 3152 has a plurality of second grooves 31521 arranged circumferentially (see Fig.19 ); The second plug-in 3153 is radially inserted into the rotating connection member 314 in the rotating hole 3111, so that when the clamping device 2 and the rotating connection member 314 rotate relative to the sleeve, the second concave-convex structure 3152 can rotate relative to the second concave-convex structure 3152 and can be concave-convexly matched with the corresponding second groove 31521. For example, Fig.18As shown, the rotating connecting member 314 is radially provided with a seventh mounting hole 3141 (see Figure 4 ), the second plug-in 3153 is inserted into the seventh mounting hole 3141 to be fixedly mounted on the rotating connecting member 314.

[0096] It can be understood that the second plug-in 3153 is fixedly mounted on the rotating connection member 314. In this way, when the rotating connection member 314 and the clamping device 2 rotate relative to the sleeve, the second plug-in 3153 can also rotate together with the rotating connection member 314 in the rotating hole 3111, and the second plug-in 3153 can be stuck in the second groove 31521 of the second concave-convex structure 3152 or disengaged from the second groove 31521 during the rotation together with the rotating connection member 314 and the clamping device 2. If the second plug-in 3153 is rotated to match the second groove 31521 with the concave-convex structure 3152, due to the obstruction of the second concave-convex structure 3152, the clamping device 2 and the rotating connection member 314 will continue to intermittently stop during the 360-degree rotation, so as to realize the fixed-point angle adjustment of the target parts such as the filter device.

[0097] It should be noted that the structure of the second damping component 315 is not limited to this structure, and may also be other suitable existing or newly created structures, which will not be described in detail here.

[0098] For example, in order to realize the buffering effect of the second elastic member 317 on the circumferential damping rotation of the clamping device 2 and the rotating connecting member 314, in some specific embodiments, as Figure 5 , Figure 6 and Figure 8 As shown, the above-mentioned limiting member 316 is a slide cylinder, wherein the slide cylinder is located on the side of the second rotating shaft 3151 away from the second plug-in 3153, and the slide cylinder is slidably sleeved on the rotating connecting member 314 in the rotating hole 3111, and one end of the slide cylinder can abut against the clamping device 2; the two ends of the second elastic member 317 are respectively limited at the second rotating shaft 3151 and the other end of the slide cylinder, so as to be axially squeezed by the slide cylinder when the second plug-in 3153 is separated from the corresponding second groove 31521.

[0099] Further exemplary, the slide cylinder is provided with a slide hole 3161 axially (see Fig.21 and Fig. 22 ), one end of the rotating connecting member 314 passes through the sliding hole 3161 and is fixedly connected to the clamping device 2, wherein the aperture of the sliding hole 3161 is slightly larger than the axial diameter of the rotating connecting member 314, so that the slide cylinder can slide axially relative to the rotating connecting member 314. In addition, under normal conditions, one end of the slide cylinder abuts against the clamping device 2. The other end of the slide cylinder (i.e., the end close to the second plug-in 3153) is also axially provided with a limiting groove 3162 (see Fig.21), wherein one end of the second elastic member 317 is inserted into the limiting groove 3162 and is limited and supported by the slide cylinder, and the other end is sleeved or abutted against the second rotating shaft 3151 to be limited between the second rotating shaft 3151 and the slide cylinder.

[0100] It can be understood that when the rotating connection member 314, the clamping device 2 and the second plug-in 3153 rotate circumferentially relative to the sleeve and the mounting seat 1, the rotating connection member 314 will have a slight axial movement in the process of the second plug-in 3153 disengaging from the corresponding second groove 31521. When the rotating connection member 314 moves axially, the clamping device 2 fixedly connected to the rotating connection member 314 will also move axially accordingly, so that the clamping device 2 will press against the slide cylinder that is against the clamping device 2, so that the slide cylinder moves axially in the direction of the second plug-in 3153. In this way, the slide cylinder will axially squeeze the second elastic member 317 to generate an elastic compression force.

[0101] On the one hand, the elastic compression force can quickly reset the rotating connecting member 314 so that the second plug-in 3153 maintains close contact with the second groove 31521 of the second concave-convex structure 3152, thereby ensuring that the target part such as the filter device clamped by the clamping device 2 can be more safely and reliably adjusted in angle; on the other hand, the elastic compression force can buffer the damping rotation of the clamping device 2, so that the target part such as the filter device clamped by the clamping device 2 can achieve fixed-point angle adjustment more smoothly and conveniently.

[0102] Alternatively, in some other specific embodiments of the present invention, in order to achieve the buffering effect of the second elastic member 317 on the circumferential damping rotation of the clamping device 2 and the rotating connecting member 314, the above-mentioned limit member 316 is arranged on the outer wall of the rotating connecting member 314, and is located on the side of the second rotating shaft 3151 away from the second plug-in 3153; the two ends of the second elastic member 317 are respectively limited to the second rotating shaft 3151 and the limit member 316, so as to be axially squeezed by the limit member 316 when the second plug-in 3153 is separated from the corresponding second groove 31521.

[0103] Similarly, it can be understood that when the rotating connector 314, the clamping device 2 and the second plug-in 3153 rotate circumferentially relative to the sleeve and the mounting seat 1, the rotating connector 314 will have a slight axial movement during the process of the second plug-in 3153 disengaging from the corresponding second groove 31521. When the rotating connector 314 moves axially, the limit member 316 arranged on the rotating connector 314 will also move toward the second rotating shaft 3151, so that the limit member 316 will axially squeeze the second elastic member 317 to generate an elastic compression force, so that the second plug-in 3153 maintains close contact with the second concave-convex structure 3152, and ensures that the filter device can achieve fixed-point angle adjustment more smoothly and conveniently.

[0104] In some specific implementations of this embodiment 1, Figures 1 to 4 , Fig.23 and Fig.24 As shown, in order to realize that the clamping device 2 can clamp target parts such as filter devices of different sizes, the clamping device 2 also includes a rotating connecting shaft 24 and a third elastic member 25, wherein the rotating connecting shaft 24 is inserted into the first clamping member 21 and the second clamping member 22 arranged oppositely, so that the first clamping member 21 and the second clamping member 22 rotate relative to the rotating connecting shaft 24. In addition, the third elastic member 25 includes an elastic body 251 and a first abutting end 252 and a second abutting end 253 extending from both sides of the elastic body 251, wherein the elastic body 251 is sleeved on the rotating connecting shaft 24, the first abutting end 252 abuts against the first clamping member 21, and the second abutting end 253 abuts against the second clamping member 22.

[0105] Understandably, when the first clamping member 21 and the second clamping member 22 rotate relative to the rotating connecting shaft 24 to adjust the size of the clamping space 23, the first abutment end 252 and the second abutment end 253 of the third elastic member 25 are respectively squeezed by the first clamping member 21 and the second clamping member 22 to generate elastic expansion and contraction force. On the one hand, the elastic expansion and contraction force can enable the first clamping member 21 and the second clamping member 22 to firmly clamp the target member such as the filter device in the clamping space 23; on the other hand, the elastic expansion and contraction force plays an elastic buffering role in the opening or closing between the first clamping member 21 and the second clamping member 22, so as to automatically adjust the clamping force between the first clamping member 21 and the second clamping member 22 to avoid physical damage caused by clamping too tightly or falling caused by clamping too loosely. That is, the clamping force between the first clamping member 21 and the second clamping member 22 can ensure the clamping completeness of the filter device on the basis of ensuring the stable clamping of the filter device, so as to achieve firm and safe clamping according to different sizes.

[0106] For example, in order to realize the relative rotation of the first clamping member 21 and the second clamping member 22 around the rotating connecting shaft 24 by rotating the connecting shaft 24, two eighth mounting holes 212 (see FIG. Fig.24 ), the mounting frame of the second clamping member 22 is provided with two ninth mounting holes 222 spaced apart from each other (see Figure 4 ),like Figure 1 , Figure 3 and Figure 4As shown, the mounting frame of the second clamping member 22 is inserted between the two eighth mounting holes 212, or, in other specific embodiments, the mounting frame of the first clamping member 21 can also be inserted between the two ninth mounting holes 222, which can be determined according to the actual opening positions of the two ninth mounting holes 222 and the two eighth mounting holes 212. Then, the rotation connection shaft 24 is inserted into the two eighth mounting holes 212 and the two ninth mounting holes 222, so that the first clamping member 21 and the second clamping member 22 are rotationally connected around the rotation connection shaft 24.

[0107] For example, in order to facilitate the adjustment of the size of the clamping space 23 between the first clamping member 21 and the second clamping member 22, as shown in FIG. Figures 1 to 3 As shown, the first clamping member 21 has a first handle 211, and the second clamping member 22 has a second handle 221, wherein the first handle 211 and the second handle 221 are located on the same side, so that the operator can directly hold the first handle 211 and the second handle 221 with their hands to control the opening or closing of the clamping device 2, thereby improving the convenience of the clamping device 2 in adjusting the size of the clamping space 23.

[0108] For example, in this embodiment, the first clamping member 21 is a stationary arm, and the second clamping member 22 is a movable arm. Figure 4 , Fig.23 and Fig.24 As shown, in order to achieve the fixed connection between the above-mentioned rotating connection member 314 and the clamping device 2, the first clamping member 21 is provided with a first connecting hole 213 along the axial direction of the rotating connection member 314, and the first clamping member 21 is also provided with a second connecting hole 214 in radial direction of the rotating connection member 314, which is communicated with the first connecting hole 213, and a third connecting hole 3142 is radially provided at one end of the rotating connection member 314, wherein one end of the rotating connection member 314 is plugged into the first connecting hole 213, and the rotating connection member 314 is sequentially inserted into the second connecting hole 214, the first connecting hole 213, the third connecting hole 3142 and the second connecting hole 214 through the latch 3155 to be fixedly connected to the first clamping member 21, so as to ensure that the rotating connection member 314 and the clamping device 2 rotate circumferentially relative to the sleeve and the mounting seat 1, thereby realizing the independent and smooth 360-degree rotation function of the clamping device 2.

[0109] Alternatively, in some other specific implementations of the first embodiment, in order to enable the clamping device to clamp target parts such as filter devices of different sizes, the clamping device (not shown) also includes a connecting seat (not shown) connected to the connecting arm 31 for damping rotation, wherein the first clamping member (not shown) and the second clamping member (not shown) are relatively arranged with respect to the connecting seat, and a clamping space (not shown) is formed between the first clamping member, the connecting seat and the second clamping member, and at least one of the first clamping member and the second clamping member is connected to the connecting seat for damping sliding.

[0110] Of course, in other specific implementations, the clamping device may also adopt other existing or newly created structures, as long as the size of the clamping space can be adjusted, and no special limitation is made here.

[0111] Embodiment 2 of the filter clip 100 of the present invention

[0112] The main technical features of this embodiment are substantially the same as those of the above-mentioned embodiment 1, and the main difference between this embodiment and embodiment 1 lies in that the specific structure of the pitch rotation assembly 32 between the mounting base 1 and the connecting arm 31 is different. For example, the connecting arm 31 and the first connecting axis 321 remain stationary, and the connecting arm 31 rotates relative to the mounting base 1 and the first connecting axis 321, instead of the connecting arm 31 and the first connecting axis 321 in embodiment 1 rotating together relative to the mounting base 1.

[0113] For example, in some specific implementations of the second embodiment, the mounting seat includes a seat body 11 and two support frames (not shown) arranged side by side with a gap, and the connecting arm includes an arm body 311 and a connecting portion (not shown), wherein the connecting portion of the connecting arm is connected to the end of the arm body 311, and the connecting portion of the connecting arm is inserted into the gap between the two support frames of the mounting seat (not shown). The first connecting shaft (not shown) is inserted into the connecting portion of the connecting arm and the two support frames of the mounting seat to enable the connecting arm to rotate relative to the first connecting shaft and the mounting seat. It should be noted that in this embodiment, the first connecting shaft and the mounting seat are fixedly connected, that is, the first connecting shaft mainly serves to enable the connecting arm and the mounting seat to be rotatably connected, and does not rotate itself.

[0114] In addition, illustratively, the outer wall of the first connecting shaft is convexly provided with a limiting rib (not shown), and the first damping assembly (not shown) includes a first concave-convex structure and a first plug rod, wherein the first concave-convex structure is provided on the connecting portion of the connecting arm and has a plurality of first grooves arranged circumferentially; the first plug rod is radially plugged into the first connecting shaft, so as to rotate relative to the first concave-convex structure when the connecting arm rotates relative to the mounting seat and the first connecting shaft, and can be concave-convexly matched with the first groove. The first elastic member is located between the limiting rib and the first concave-convex structure, so as to be axially squeezed by the limiting rib when the first plug rod is separated from the corresponding first groove.

[0115] It can be understood that the first plug-in is fixedly installed on the first connecting shaft, and is fixed relative to the mounting seat together with the first connecting shaft, and the first concave-convex structure is located on the connecting part of the rotating connecting arm. In this way, when the connecting arm rotates relative to the first connecting shaft and the mounting seat, the first concave-convex structure can rotate with the connecting arm, and during the rotation of the first concave-convex structure, the first plug-in connected to the first connecting shaft can be inserted into the first groove of the first concave-convex structure, and can also be separated from the first groove. If the concave-convex of the first plug-in fits into the first groove, the pitch rotation of the connecting arm and the clamping device can be stuck or paused, so as to realize the fixed-point height adjustment of the target parts such as the filter device.

[0116] If the first plug-in is disengaged from the corresponding first groove, the first connecting shaft and the limiting rib will move slightly axially, so that the first elastic member can be squeezed by the limiting rib in the direction of the first concave-convex structure to generate an elastic expansion force. In this way, on the one hand, the first connecting shaft can be quickly restored to its original position, so as to ensure that the first plug-in quickly returns to cooperate with the corresponding first groove, thereby ensuring that the height adjustment of the target member such as the filter device clamped by the clamping device is safer and more reliable; on the other hand, it can buffer the damping rotation between the connecting arm and the mounting seat, so that the fixed-point height adjustment of the target member can be achieved more smoothly and conveniently without too much effort.

[0117] Based on the above-mentioned filter clamp 100, an embodiment of the utility model also provides a blood purification device 1000, wherein the blood purification device 1000 includes the above-mentioned filter clamp 100, and also includes a main body 200 and a filter device (not shown), wherein the filter clamp 100 is arranged on the main body 200 for clamping the filter device.

[0118] In summary, compared with the prior art, the blood purification device 1000 has at least the following beneficial effects: the blood purification device 1000, by adopting the above-mentioned filter clamp 100, can not only clamp filter devices of different sizes to ensure the stability and physical safety of the filter device clamping, but also drive the filter device to rotate 360 ​​degrees to arbitrarily adjust the orientation of the filter device, and / or make a pitch movement to arbitrarily adjust the height of the filter device within the height adjustment range. The filter clamp 100 of the blood purification device 1000 is convenient and smooth in all operations of clamping the filter device, and has diverse functions and high safety, which is conducive to meeting the actual needs of clinical blood purification.

[0119] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the scope of the claims of the utility model.
