Description

Technical Field

[0001] The utility model relates to the technical field of dialyzer processing and production, in particular to a fixing mechanism and a centrifugal rotating carrier. Background Art

[0002] The dialyzer glue injection process is one of the important processes on the dialyzer product production line. The purpose of centrifugal glue injection is to fill the gaps between the hollow fiber membrane bundles at both ends of the dialyzer with glue, so that when the patient uses the dialyzer product, the blood can only pass through the middle of the hollow fiber membrane, avoiding blood from entering the gaps between the hollow fiber membrane bundles and flowing out together with the dialysate, causing waste.

[0003] The traditional centrifugal rotating carrier adopts a spring plate and can accommodate two dialyzers. Since the spring plate is always subjected to the force of the spring, when the dialyzer is manually loaded into the centrifugal carrier, it will encounter greater resistance from the spring plate. It is impossible to load two or more dialyzers into the centrifugal rotating carrier at one time. The only way is to load two dialyzers in turn and then install the distributor on the dialyzer. That is, the dialyzer needs to be loaded first and then the distributor. The distributor port and the dialyzer need to be aligned in the centrifugal carrier before assembly, which increases the difficulty of manual loading and reduces the loading efficiency. Utility Model Content

[0004] The utility model aims to provide a fixing mechanism and a centrifugal rotating carrier, which are convenient for loading the assembled dialyzer and distributor into the centrifugal carrier together, and the top block can stably clamp the two ends of the dialyzer, reduce the difficulty of manual loading, and improve the loading efficiency.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] In a first aspect, the utility model provides a fixing mechanism, including a bracket, a swing rod and a clamping assembly;

[0007] The swing rod is rotatably connected to the bracket, and the swing path of the swing rod includes a starting point when not subject to centrifugal force and an end point when subject to centrifugal force;

[0008] The clamping assembly includes a top block and a connecting block, wherein the two ends of the top block along the plumb direction are rotatably connected to the swing rod and one end of the connecting block respectively, and the other end of the connecting block is rotatably connected to the bracket. When the swing rod rotates from the starting point to the end point, the top block moves away from the bracket under the push of the swing rod.

[0009] When the swing arm is not subjected to centrifugal force, the swing arm is located at the starting point of the swing path under the action of gravity, and the two top blocks in the oppositely arranged fixing mechanism are in a state of being away from each other, and there is enough space for manual discharge. At this time, the assembled dialyzer and dispenser can be placed together in the centrifugal rotating carrier; when the swing arm is subjected to centrifugal force, the swing arm swings under the action of centrifugal force, and the swing arm gradually swings to the end point of the swing path. During this process, the swing arm pushes the top block to move away from the bracket, which can press the end of the dialyzer, and the connecting block swings accordingly to cooperate with the swing arm to support the top block, thereby fixing the dialyzer.

[0010] Compared with the prior art, the fixing mechanism provided in the first aspect of the utility model facilitates loading the assembled dialyzer and distributor into the centrifugal carrier together. Since the connecting block and the rocker arm cooperate to support and limit the top block, the top block can stably clamp the two ends of the dialyzer during centrifugal rotation, reducing the difficulty of manual loading and improving loading efficiency.

[0011] Furthermore, the bracket and the top block are both rotatably connected to the top of the rocker arm, the position at which the rocker arm is rotatably connected to the bracket is lower than the position at which it is rotatably connected to the top block, and the position at which the connecting block is rotatably connected to the bracket is lower than the position at which it is rotatably connected to the top block.

[0012] The above arrangement enables the end of the swing arm connected to the top block to push the top block to the left when the swing arm rotates counterclockwise due to centrifugal force, and the connecting block rotates counterclockwise following the top block, so that the top block is close to the end of the dialyzer in the horizontal direction, thereby clamping the end of the dialyzer.

[0013] Furthermore, a counterweight block is provided at the bottom of the swing rod.

[0014] The setting of the counterweight block can make the swing rod be subjected to a greater centrifugal force, and the force applied by the swing rod to the top block increases accordingly, and the clamping surface of the top block can clamp the end face of the dialyzer more firmly.

[0015] Furthermore, it also includes an elastic member, which is connected to the bracket, and cooperates with the swing rod to limit the swing rod to the starting point when it is not subjected to centrifugal force.

[0016] The elastic member can limit the swing arm to the starting point when not subject to centrifugal force, thereby forming a space sufficient to accommodate the dialyzer between the top blocks in the two relatively arranged fixing mechanisms, making it easier to load the assembled dialyzer and distributor into the centrifugal carrier together.

[0017] Furthermore, the elastic member includes a first leg, a second leg and a spiral portion connecting the first leg and the second leg, the spiral portion is connected to the bracket, the first leg is against the bracket, and the second leg cooperates with the rocker arm and applies elastic force to the rocker arm.

[0018] The elastic member has a simple structure, and the bracket can limit the positions of the spiral portion and the first leg, so that the second leg applies an elastic force to the swing rod, so that the swing rod is limited to the starting point.

[0019] Furthermore, the bracket is provided with a first fixed shaft, the spiral portion is sleeved on the first fixed shaft, and the swing arm is rotatably connected to the first fixed shaft.

[0020] The above arrangement enables both the spiral portion and the rocker arm to cooperate with the first fixed shaft, without the need for an additional support structure for mounting the spiral portion, which can make the structure of the fixing mechanism simpler and more integrated.

[0021] Furthermore, the bracket is provided with a first protrusion, the outer circumferential surface of the first protrusion is provided with a first groove engaged with the first leg, the rocker arm is provided with a second protrusion, and the outer circumferential surface of the second protrusion is provided with a second groove engaged with the second leg.

[0022] The above arrangement can prevent the first leg from being separated from the first protrusion during use, and prevent the second leg from being separated from the second protrusion.

[0023] In a second aspect, the utility model also provides a centrifugal rotating carrier, comprising a distributor positioning plate and a plurality of pairs of fixing mechanisms described in the above scheme with different heights, wherein the plurality of pairs of fixing mechanisms are distributed around the distributor positioning plate, and the two fixing mechanisms in each pair of the fixing mechanisms have the same height.

[0024] The centrifugal rotating carrier provided by the second aspect of the utility model includes a distributor positioning plate and multiple pairs of fixing mechanisms. When the assembled dialyzer and the distributor are placed together in the centrifugal rotating carrier, the distributor positioning plate can play a positioning role for the distributor, and each pair of fixing mechanisms can clamp the two ends of a dialyzer during centrifugal rotation, thereby simultaneously clamping multiple dialyzers during rotation. Compared with the prior art, the centrifugal rotating carrier provided by the second aspect of the utility model is convenient for loading after assembling multiple dialyzers and the distributor, and the loading efficiency is higher.

[0025] Furthermore, the centrifugal rotating carrier also includes a base and a driving mechanism, the distributor positioning plate and each of the fixing mechanisms are installed on the base, the power output end of the driving mechanism is connected to the base, and the power output end of the driving mechanism drives the base to rotate.

[0026] The centrifugal rotating carrier has a simple structure and realizes the synchronous rotation of multiple fixing mechanisms through a driving mechanism, thereby ensuring the stability of the position of the dialyzer during centrifugation.

[0027] Furthermore, the centrifugal rotating carrier also includes a detection photoelectric device for detecting the rotation angle of the base.

[0028] The photoelectric detection can be used to detect the rotation angle of the base, realize real-time monitoring of the rotation angle of the base, and make it easier for personnel to understand the rotation status of the centrifugal rotating carrier.

[0029] Furthermore, the centrifugal rotating carrier also includes a workbench and a cylinder, the cylinder is supported on the upper surface of the workbench by a plurality of supporting legs, the base and each of the fixing mechanisms are arranged in the cylinder, and the driving mechanism is installed on the lower surface of the workbench.

[0030] Among them, the cylinder can protect the fixing mechanism, distributor and dialyzer inside it to avoid external interference during the centrifugation process. The workbench plays the role of supporting the cylinder to ensure that the centrifugation process proceeds more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0045] The first aspect of the present invention provides a fixing mechanism. Figure 1 and Figure 2 As shown, it includes a bracket 1, a swing rod 2 and a clamping assembly 4;

[0046] The swing rod 2 is rotatably connected to the bracket 1, and the swing path of the swing rod 2 includes a starting point when it is not subjected to centrifugal force and an end point when it is subjected to centrifugal force;

[0047] The clamping assembly 4 includes a top block 41 and a connecting block 42. The two ends of the top block 41 along the plumb direction are rotatably connected to the pendulum 2 and one end of the connecting block 42 respectively. The other end of the connecting block 42 is rotatably connected to the bracket 1. When the pendulum 2 rotates from the starting point to the end point, the top block 41 moves away from the bracket 1 under the push of the pendulum 2.

[0048] The fixing mechanism provided in the above embodiment does not require manual work to overcome the large resistance of the spring plate, which makes it easy to load the assembled dialyzer and distributor into the centrifugal carrier together. At the same time, due to the setting of the connecting block 42, the position of the top block 41 relative to the bracket 1 is always stable regardless of whether the rocker arm 2 is at the starting point or the end point. The clamping surface 411 of the top block 41 can more evenly transmit the clamping force to the end of the dialyzer, ensuring that the top blocks 41 on the two fixing mechanisms stably clamp the two ends of the dialyzer during centrifugal rotation, reducing the difficulty of manual loading and improving loading efficiency.

[0049] In an optional embodiment, the bracket 1 and the top block 41 are both rotationally connected to the top of the rocker arm 2, the position at which the rocker arm 2 is rotationally connected to the bracket 1 is lower than the position at which it is rotationally connected to the top block 41, and the position at which the connecting block 42 is rotationally connected to the bracket 1 is lower than the position at which it is rotationally connected to the top block 41.

[0050] like Figure 4 As shown, the above arrangement enables the end of the rocker arm 2 connected to the top block 41 to push the top block 41 to the left when the rocker arm 2 rotates counterclockwise due to the centrifugal force, and at the same time, the connecting block 42 rotates counterclockwise following the top block 41, so that the top block 41 is close to the end of the dialyzer in the horizontal direction, thereby clamping the end of the dialyzer.

[0051] Reference Figure 1 and Figure 3 The use process of the fixing mechanism is described in detail:

[0052] The top end of the top block 41 is hinged to the swing rod 2, and the bottom end of the top block 41 is hinged to the connecting block 42. The bracket 1, the swing rod 2, the top block 41 and the connecting block 42 can be regarded as forming a hinge four-bar mechanism. When the swing rod 2 is not subjected to centrifugal force, the swing rod 2 is located at the starting point of the swing path under the action of gravity, that is, Figure 3 At the position shown by the dotted line in the figure, the two top blocks 41 in the oppositely arranged fixing mechanism are in a state of being away from each other, and there is enough space for manual discharge. At this time, the assembled dialyzer and the distributor can be placed in the centrifugal rotating carrier together; when the pendulum 2 is subjected to the centrifugal force, the pendulum 2 swings counterclockwise under the action of the centrifugal force, and the pendulum 2 gradually swings to the end of the swing path, that is, Figure 3 At the position shown by the solid line in the figure, during this process, the swing rod 2 pushes the top block 41 to press the end of the dialyzer, and the connecting block 42 swings accordingly to cooperate with the swing rod 2 to support the top block 41, thereby fixing the dialyzer.

[0053] It should be noted that, in actual use, the swing angle between the starting point and the end point of the swing rod 2 can be set to be relatively small, so that the top block 41 can quickly clamp the end of the dialyzer when the fixing mechanism rotates. Figure 3 The illustration that the swing rod 2 has a larger swing angle is only for the sake of understanding, and does not limit the actual swing angle of the swing rod 2 .

[0054] The pendulum 2 can be kept at the starting position by its own weight, and can swing by its own weight under the action of centrifugal force. In order to make the centrifugal force on the pendulum 2 greater when the fixing mechanism rotates, in an optional embodiment, as Figure 2 As shown, the bottom of the rocker 2 has a counterweight 22 .

[0055] The arrangement of the counterweight block 22 can subject the swing rod 2 to a greater centrifugal force, and the force applied by the swing rod 2 to the top block 41 increases accordingly, so that the clamping surface 411 of the top block 41 can clamp the end face of the dialyzer more firmly.

[0056] In an optional embodiment, if Figure 5 As shown, the fixing mechanism further includes an elastic member 3, which is connected to the bracket 1. The elastic member 3 cooperates with the swing rod 2 to limit the swing rod 2 to a starting point when it is not subjected to centrifugal force.

[0057] In the above embodiment, the elastic member 3 can limit the rocker arm 2 to the starting point when it is not subjected to centrifugal force, so that a space sufficient for placing the dialyzer is formed between the top blocks 41 in the two relatively arranged fixing mechanisms, making it easier to load the assembled dialyzer and distributor into the centrifugal carrier together.

[0058] Of course, in other embodiments, the elastic member 3 may not be provided.

[0059] In an optional embodiment, when the fixing mechanism includes an elastic member 3, as Figure 5 and Figure 6 As shown, the elastic member 3 may include a first leg 31, a second leg 32 and a spiral portion 33 connecting the first leg 31 and the second leg 32, the spiral portion 33 is connected to the bracket 1, the first leg 31 is against the bracket 1, and the second leg 32 cooperates with the rocker arm 2 and applies elastic force to the rocker arm 2.

[0060] In the above embodiment, the elastic member 3 has a simple structure, and the bracket 1 can limit the positions of the spiral portion 33 and the first leg 31 , so that the second leg 32 applies elastic force to the swing rod 2 to limit the swing rod 2 to the starting point.

[0061] In an optional embodiment, if Figure 5 As shown, the bracket 1 is provided with a first fixed shaft 11 , the spiral portion 33 is sleeved on the first fixed shaft 11 , and the swing rod 2 is rotationally connected to the first fixed shaft 11 , thereby realizing the rotational connection between the swing rod 2 and the bracket 1 .

[0062] In the above embodiment, the spiral portion 33 and the rocker arm 2 are both matched with the first fixed shaft 11, and there is no need to additionally provide a supporting structure for installing the spiral portion 33, which can make the structure of the fixing mechanism simpler and more integrated.

[0063] In an optional embodiment, if Figure 5 As shown, the bracket 1 is provided with a first protrusion 12, and the outer peripheral surface of the first protrusion 12 is provided with a first groove 121 which is engaged with the first leg 31. The setting of the first groove 121 can make the position of the first leg 31 relative to the first protrusion 12 more stable when it is against the first protrusion 12, thereby avoiding the first leg 31 from being separated from the first protrusion 12 during use.

[0064] In an optional embodiment, if Figure 5 As shown, a second protrusion 21 is provided on the rocker arm 2, and a second groove 211 is provided on the outer peripheral surface of the second protrusion 21 for engaging with the second leg 32. The setting of the second groove 211 enables the second leg 32 to be more stable relative to the second protrusion 21 when it abuts against the second protrusion 21, thereby preventing the second leg 32 from being separated from the second protrusion 21 during use.

[0065] The first groove 121 and the second groove 211 may be respectively distributed at local positions of the circumference of the first protrusion 12 and the second protrusion 21 , or may respectively surround the entire circumference of the first protrusion 12 and the second protrusion 21 .

[0066] In a preferred embodiment, the first groove 121 and the second groove 211 surround the entire circumference of the first protrusion 12 and the second protrusion 21 respectively, which makes it easier to process the two grooves.

[0067] The second aspect of the present invention provides a centrifugal rotating carrier. Figure 7 As shown, the centrifugal rotating carrier provided by the embodiment of the second aspect of the utility model includes a distributor positioning plate 5 and multiple pairs of the above-mentioned fixing mechanisms with different heights. The multiple pairs of fixing mechanisms are distributed around the distributor positioning plate 5, and the two fixing mechanisms in each pair of fixing mechanisms have the same height.

[0068] The centrifugal rotating carrier provided in the second aspect of the utility model includes a distributor positioning plate and multiple pairs of fixing mechanisms. When the assembled dialyzer and distributor are placed in the centrifugal rotating carrier together, the distributor positioning plate 5 can position the distributor. The two fixing mechanisms in each pair of fixing structures are diagonally arranged, so as to clamp the two ends of a dialyzer during centrifugal rotation. Multiple pairs of fixing mechanisms can clamp multiple dialyzers at the same time during rotation, which is convenient for loading after the multiple dialyzers are assembled with the distributor, and the loading efficiency is higher.

[0069] In an optional embodiment, the centrifugal rotating carrier also includes a base 6 and a driving mechanism 7, the distributor positioning plate 5 and each fixing mechanism are installed on the base 6, the power output end of the driving mechanism 7 is connected to the base 6, and the power output end of the driving mechanism 7 drives the base 6 to rotate, thereby realizing the synchronous rotation of each fixing mechanism.

[0070] The centrifugal rotating carrier has a simple structure and realizes the synchronous rotation of multiple fixing mechanisms through a driving mechanism 7, thereby ensuring the stability of the position of the dialyzer during centrifugation.

[0071] The driving mechanism 7 can be, but is not limited to, a rotary motor.

[0072] In an optional embodiment, the centrifugal rotating carrier further includes a detection photoelectric device for detecting the rotation angle of the base 6 .

[0073] The photoelectric detection can be used to detect the rotation angle of the base 6, so as to realize real-time monitoring of the rotation angle of the base 6, and make it easier for personnel to understand the rotation state of the centrifugal rotating carrier.

[0074] In an optional embodiment, if Figure 7 and Figure 8 As shown, the centrifugal rotating carrier also includes a workbench 8 and a cylinder 9. The cylinder 9 is supported on the upper surface of the workbench 8 by a plurality of supporting legs 10, and its position relative to the workbench 8 remains unchanged. The base 6 and various fixing mechanisms are arranged in the cylinder 9. The base 6 can rotate relative to the cylinder 9. The bottom wall of the cylinder 9 can be provided with the above-mentioned detection photoelectric. The driving mechanism 7 is installed on the lower surface of the workbench 8, and the power output shaft of the driving mechanism 7 passes through the workbench 8 and the cylinder 9 to drive the base 6 to rotate.

[0075] In the above embodiment, the cylinder 9 can protect the fixing mechanism, the distributor and the dialyzer therein to avoid external interference during the centrifugation process. The workbench 8 supports the cylinder 9 to ensure that the centrifugation process proceeds more smoothly.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
