Description

Technical Field

[0001] The invention relates to the technical field of mixing devices, in particular to a rupture-proof mixing device for a whole blood cell marker diagnostic reagent. Background Art

[0002] Whole blood cell marker diagnostic reagents are reagents used to detect the levels of specific cells or molecules in the blood, usually for disease diagnosis, monitoring disease progression or evaluating treatment effects; these reagents are widely used in medical laboratories and clinical medicine and can provide important biological information; the reagents need to be mixed before testing;

[0003] Existing mixing devices usually consist of a conveying device and a shaking device. The mixing device can only mix a few reagent samples at a time, which is very inefficient. In addition, during the mixing process, whole blood cells may rupture due to excessive centrifugal force, thereby affecting subsequent testing and reducing the accuracy of the test. Summary of the invention

[0007] Preferably, a motor is provided in the rotating chamber, a driving shaft of the motor is connected to the bottom of the rotating device, and a reagent tube is placed in the placement tray;

[0008] The staff places the reagent tubes in the placement tray, and then the controller controls the motor to start. The drive shaft in the motor drives the rotating device to rotate, and the rotating device then rotates around the axis of the drive shaft. While the motor drives the rotating device to rotate, the controller controls the rotating device to start, and the rotating device then drives each reagent tube to rotate individually, so that while the rotating device rotates over a large range, the reagent tubes also rotate individually, thereby improving the mixing of the whole blood cells in the reagent tubes, thereby improving the mixing effect of the whole blood cells. At the same time, the speed of the motor and the rotating device can be used to control the mixing rate of the reagent tubes, thereby avoiding the rupture of the whole blood cells during the mixing process, thereby improving the quality of the whole blood cell mixing.

[0009] Preferably, a plurality of placement grooves are provided on the placement plate, and the plurality of placement grooves are arranged around the axis of the placement plate, a movable cavity is provided on one side of the placement groove close to the rotating cavity, the placement groove is connected with the movable cavity, and a placement tube is provided in the placement groove.

[0010] Preferably, a ring gear is provided on the shaft wall of the placement groove, tooth grooves are provided on the inner wall and the outer wall of the ring gear, the ring gear is rotatably connected to the placement groove, a micro motor is provided in the placement disk, an output gear is provided on the driving shaft of the micro motor, a driven gear is provided between the ring gear and the output gear, and the ring gear is meshed with the output gear through the driven gear.

[0011] Preferably, an annular gear ring is provided on one side of the placement tube close to the moving chamber, the annular gear ring is meshed with the inner wall of the annular gear, the length of the annular gear ring is greater than the length of the annular gear, a plurality of fixing rings are provided inside the placement tube, the fixing rings are connected to the inner wall of the placement tube through a bracket, a plurality of the fixing rings are vertically equally arranged along the axis of the placement tube, a support plate is provided at the bottom of the placement tube, and the bracket, fixing ring and support plate are all made of rubber.

[0012] Preferably, a plurality of movable plates are provided inside the movable cavity, the plurality of movable plates are combined into a circle, the plurality of movable plates are radially arranged along the axis of the movable cavity, a plurality of movable grooves are provided on the inner wall of the movable cavity, a movable block is provided on the side of the movable plate close to the movable groove, the movable plate is slidably connected to the movable groove through the movable block, and the bottom of the placement tube is in contact with the upper surface of the movable plate.

[0013] Preferably, a rotating shaft is provided on the side of the movable plate away from the placement groove, and a plurality of cams are provided on the rotating shaft. The plurality of cams are equally arranged along the axis of the rotating shaft, and the raised portion of each cam faces a different direction. The side wall of the cam contacts the lower surface of the movable plate, and the cam is slidably connected to the movable plate.

[0014] Preferably, one end of the rotating shaft passes through the moving cavity and is provided with a bevel gear, and an end face gear is provided inside the rotating cavity, and the bevel gear is meshed with the end face gear;

[0015] After whole blood cells are placed in the reagent tube, the staff puts the reagent tube into the placement slot, and the reagent tube passes through the fixing ring in turn, and the fixing ring then wraps and fixes the reagent tube. When the reagent tube moves to the bottom of the placement tube, the reagent tube contacts the support plate, and the support plate holds the reagent tube. The fixing ring and the support plate cooperate with each other, and the fixing ring and the support plate wrap the reagent tube, which prevents the reagent tube from colliding with the inner wall of the placement tube during the rotation and mixing process, thereby causing the reagent tube to collide and break, thereby ensuring the integrity of the reagent tube during the mixing process and improving the protection of the reagent tube;

[0016] When the reagent tube is placed, the control starts the motor in the rotating chamber. The drive shaft in the motor drives the placement plate to rotate. During the rotation of the placement plate, the placement plate drives the placement slot to rotate, and the placement slot drives the reagent tube to rotate, thereby realizing the revolution of the reagent tube around the axis of the rotating chamber;

[0017] While the reagent tube is revolving, the controller controls the micro motor in the placement plate to start, and the driving shaft in the micro motor drives the output gear to rotate. When the output gear rotates, it drives the driven gear to rotate. When the driven gear rotates, it drives the ring gear to rotate. During the rotation of the ring gear, the ring gear and the annular gear ring are meshed and transmitted, so that the annular gear ring rotates. During the rotation of the annular gear ring, the annular gear ring drives the placement tube to rotate, and the placement tube drives the reagent tube to rotate. The reagent tube mixes the whole blood cells under the condition of coordinated revolution and rotation, thereby improving the mixing efficiency of the whole blood cells. The rotation rate is regulated by the controller, so that the centrifugal intensity of the whole blood cells in the reagent tube can be small, thereby avoiding the whole blood cells being ruptured by high centrifugal force, which leads to poor subsequent detection results, thereby improving the accuracy of subsequent detection;

[0018] When the motor drives the placement plate to rotate, since the rotating shaft passes through the moving cavity and is provided with a bevel gear, during the rotation of the placement plate, the placement plate drives the rotating shaft to rotate, and the rotating shaft drives the bevel gear to rotate around the axis of the placement plate. Since the bevel gear and the end gear are in meshing rotation, when the bevel gear rotates around the placement plate, it meshes with the end gear, and during the meshing process, the bevel gear rotates around its own axis, so that when the bevel gear rotates, it drives the rotating shaft to rotate.

[0019] When the rotating shaft rotates, it drives several cams to rotate. During the rotation of the cam, the side wall of the cam contacts the moving plate. When the raised part of the cam rotates toward the side close to the moving cavity, the raised part of the cam immediately pushes the moving plate to move, and the moving block on the moving plate moves along the moving groove, and the moving plate moves toward the side close to the moving cavity. During the movement of the moving plate, the moving plate pushes the placement tube to move, and the placement tube moves to the side away from the moving plate, and the placement tube moves along the axis of the placement groove, and then the placement tube extends out of the placement groove; when the raised part of the cam rotates toward the side away from the moving plate, the moving plate moves toward the side close to the cam, and then the placement tube moves toward the side close to the cam, so that the placement tube makes a vertical reciprocating movement along the axis of the placement groove, thereby realizing the stirring of the whole blood cells in the reagent tube, further improving the efficiency of the mixing of the whole blood cells, and by coordinating the revolution, rotation and reciprocating movement of the axis of the reagent tube, the quality of the mixing of the whole blood cells in the reagent tube is improved.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] 1. When the reagent tube is placed, the controller starts the motor in the rotating chamber. The driving shaft in the motor drives the placement plate to rotate. During the rotation of the placement plate, the placement plate drives the placement slot to rotate, and the placement slot drives the reagent tube to rotate, so that the reagent tube revolves around the axis of the rotating chamber; while the reagent tube revolves, the controller controls the micro motor in the placement plate to start, and the driving shaft in the micro motor drives the output gear to rotate. When the output gear rotates, it drives the driven gear to rotate. When the driven gear rotates, it drives the ring gear to rotate. During the rotation of the ring gear, the ring gear meshes with the annular gear ring, so that the annular gear ring rotates. During the rotation of the annular gear ring, the annular gear ring drives the placement tube to rotate, and the placement tube drives the reagent tube to rotate. The reagent tube mixes the whole blood cells under the conditions of the coordination of revolution and rotation, thereby improving the efficiency of the whole blood cell mixing. The controller regulates the rotation rate, so that the whole blood cells can be centrifuged at a low intensity in the reagent tube, thereby avoiding the high centrifugal force that causes the whole blood cells to rupture, which leads to poor subsequent detection results, thereby improving the accuracy of subsequent detection.

[0022] 2. When the rotating shaft rotates, it drives several cams to rotate. During the rotation of the cam, the side wall of the cam contacts the moving plate. When the raised part of the cam rotates toward the side close to the moving cavity, the raised part of the cam immediately pushes the moving plate to move, and the moving block on the moving plate moves along the moving groove, and the moving plate moves toward the side close to the moving cavity. During the movement of the moving plate, the moving plate pushes the placement tube to move, and the placement tube moves toward the side away from the moving plate, and the placement tube moves along the axis of the placement groove, and then the placement tube extends out of the placement groove; when the raised part of the cam rotates toward the side away from the moving plate, the moving plate moves toward the side close to the cam, and then the placement tube moves toward the side close to the cam, so that the placement tube makes a vertical reciprocating movement along the axis of the placement groove, thereby realizing the stirring of the whole blood cells in the reagent tube, further improving the efficiency of the mixing of the whole blood cells, and by coordinating the revolution, rotation and reciprocating movement of the axis of the reagent tube, the quality of the mixing of the whole blood cells in the reagent tube is improved.

[0041] As a specific embodiment of the present invention, a ring gear 221 is arranged on the shaft wall of the placement groove 22, and tooth grooves are arranged on the inner wall and the outer wall of the ring gear 221.

A plurality of fixing rings 242 are provided inside the placement tube 24, and the fixing ring 242 is connected to the inner wall of the placement tube 24 through a bracket.

A support plate 243 is provided at the bottom of the placement tube 24, and the bracket, fixing ring 242 and support plate 243 are all made of rubber.

[0043] As a specific embodiment of the present invention, a plurality of movable plates 25 are arranged inside the movable chamber 23, and the plurality of movable plates 25 are combined into a circle, and the plurality of movable plates 25 are radially arranged along the axis of the movable chamber 23, and a plurality of movable grooves 26 are arranged on the inner wall of the movable chamber 23, and a movable block is arranged on the side of the movable plate 25 close to the movable groove 26, and the movable plate 25 is slidably connected to the movable groove 26 through the movable block, and the bottom of the placement tube 24 is in contact with the upper surface of the movable plate 25.

[0044] As a specific embodiment of the present invention, a rotating shaft 27 is provided on the side of the movable plate 25 away from the placement groove 22, and a plurality of cams 28 are provided on the rotating shaft 27. The plurality of cams 28 are equally arranged along the axis of the rotating shaft 27, and the raised portion of each cam 28 faces a different direction. The side wall of the cam 28 contacts the lower surface of the movable plate 25, and the cam 28 is slidably connected to the movable plate 25.

[0045] As a specific embodiment of the present invention, one end of the rotating shaft 27 passes through the moving cavity 23 and is provided with a bevel gear 30, and an end face gear 31 is provided inside the rotating cavity 11, and the bevel gear 30 is meshed with the end face gear 31;

[0046] After whole blood cells are placed in the reagent tube, the staff puts the reagent tube into the placement slot 22, and the reagent tube passes through the fixing ring 242 in turn, and the fixing ring 242 then wraps and fixes the reagent tube. When the reagent tube moves to the bottom of the placement tube 24, the reagent tube contacts the support plate 243, and the support plate 243 holds the reagent tube. The fixing ring 242 and the support plate 243 cooperate with each other, and the fixing ring 242 and the support plate 243 wrap the reagent tube, thereby preventing the reagent tube from colliding with the inner wall of the placement tube 24 during the rotation and mixing process, thereby causing the reagent tube to collide and break;

[0047] When the reagent tube is placed, the control starts the motor in the rotating chamber 11. The drive shaft in the motor drives the placement plate 21 to rotate. During the rotation of the placement plate 21, the placement plate 21 drives the placement slot 22 to rotate, and the placement slot 22 drives the reagent tube to rotate, so that the reagent tube revolves around the axis of the rotating chamber 11;

[0048] While the reagent tube is revolving, the controller controls the micro motor in the placement plate 21 to start, and the driving shaft in the micro motor drives the output gear to rotate. When the output gear rotates, it drives the driven gear to rotate. The driven gear rotates and drives the ring gear 221 to rotate. During the rotation of the ring gear 221, the ring gear 221 meshes with the annular gear ring 241, so that the annular gear ring 241 rotates. During the rotation of the annular gear ring 241, the annular gear ring 241 drives the placement tube 24 to rotate, and the placement tube 24 drives the reagent tube to rotate. The reagent tube mixes the whole blood cells under the condition of the coordination of the revolution and the rotation, and the rotation rate is regulated by the controller;

[0049] During the process of the placement plate 21 being driven by the motor to rotate, since the rotating shaft 27 passes through the moving cavity 23 and is provided with a bevel gear 30, during the rotation of the placement plate 21, the placement plate 21 drives the rotating shaft 27 to rotate, and the rotating shaft 27 drives the bevel gear 30 to rotate around the axis of the placement plate 21. Since the bevel gear 30 and the end face gear 31 are in meshing rotation, when the bevel gear 30 rotates around the placement plate 21, it meshes with the end face gear 31, and during the meshing process, the bevel gear 30 rotates around its own axis, so that when the bevel gear 30 rotates, it drives the rotating shaft 27 to rotate.

[0050] When the rotating shaft 27 rotates, it drives several cams 28 to rotate. During the rotation of the cam 28, the side wall of the cam 28 contacts the moving plate 25. When the raised part of the cam 28 rotates toward the side close to the moving chamber 23, the raised part of the cam 28 immediately pushes the moving plate 25 to move, and the moving block on the moving plate 25 moves along the moving groove 26. The moving plate 25 moves toward the side close to the moving chamber 23. During the movement of the moving plate 25, the moving plate 25 pushes the placement tube 24 to move, and the placement tube 24 moves toward the side away from the moving plate 25. The placement tube 24 moves along the axis of the placement groove 22, and then the placement tube 24 extends out of the placement groove 22; when the raised part of the cam 28 rotates toward the side away from the moving plate 25, the moving plate 25 moves toward the side close to the cam 28, and then the placement tube 24 moves toward the side close to the cam 28, so that the placement tube 24 makes a vertical reciprocating movement along the axis of the placement groove 22, thereby realizing the stirring of the whole blood cells in the reagent tube.

[0051] Working principle of the present invention:

[0052] After whole blood cells are placed in the reagent tube, the staff puts the reagent tube into the placement slot 22, and the reagent tube passes through the fixing ring 242 in turn, and the fixing ring 242 then wraps and fixes the reagent tube. When the reagent tube moves to the bottom of the placement tube 24, the reagent tube contacts the support plate 243, and the support plate 243 holds the reagent tube. The fixing ring 242 and the support plate 243 cooperate with each other, and the fixing ring 242 and the support plate 243 wrap the reagent tube, thereby preventing the reagent tube from colliding with the inner wall of the placement tube 24 during the rotation and mixing process, thereby causing the reagent tube to collide and break;

[0053] When the reagent tube is placed, the control starts the motor in the rotating chamber 11. The drive shaft in the motor drives the placement plate 21 to rotate. During the rotation of the placement plate 21, the placement plate 21 drives the placement slot 22 to rotate, and the placement slot 22 drives the reagent tube to rotate, so that the reagent tube revolves around the axis of the rotating chamber 11;

[0054] While the reagent tube is revolving, the controller controls the micro motor in the placement plate 21 to start, and the driving shaft in the micro motor drives the output gear to rotate. When the output gear rotates, it drives the driven gear to rotate. The driven gear rotates and drives the ring gear 221 to rotate. During the rotation of the ring gear 221, the ring gear 221 meshes with the annular gear ring 241, so that the annular gear ring 241 rotates. During the rotation of the annular gear ring 241, the annular gear ring 241 drives the placement tube 24 to rotate, and the placement tube 24 drives the reagent tube to rotate. The reagent tube mixes the whole blood cells under the condition of the coordination of the revolution and the rotation, and the rotation rate is regulated by the controller;

[0055] During the process of the placement plate 21 being driven by the motor to rotate, since the rotating shaft 27 passes through the moving cavity 23 and is provided with a bevel gear 30, during the rotation of the placement plate 21, the placement plate 21 drives the rotating shaft 27 to rotate, and the rotating shaft 27 drives the bevel gear 30 to rotate around the axis of the placement plate 21. Since the bevel gear 30 and the end face gear 31 are in meshing rotation, when the bevel gear 30 rotates around the placement plate 21, it meshes with the end face gear 31, and during the meshing process, the bevel gear 30 rotates around its own axis, so that when the bevel gear 30 rotates, it drives the rotating shaft 27 to rotate.

[0056] When the rotating shaft 27 rotates, it drives several cams 28 to rotate. During the rotation of the cam 28, the side wall of the cam 28 contacts the moving plate 25. When the raised part of the cam 28 rotates toward the side close to the moving chamber 23, the raised part of the cam 28 immediately pushes the moving plate 25 to move, and the moving block on the moving plate 25 moves along the moving groove 26. The moving plate 25 moves toward the side close to the moving chamber 23. During the movement of the moving plate 25, the moving plate 25 pushes the placement tube 24 to move, and the placement tube 24 moves toward the side away from the moving plate 25. The placement tube 24 moves along the axis of the placement groove 22, and then the placement tube 24 extends out of the placement groove 22; when the raised part of the cam 28 rotates toward the side away from the moving plate 25, the moving plate 25 moves toward the side close to the cam 28, and then the placement tube 24 moves toward the side close to the cam 28, so that the placement tube 24 makes a vertical reciprocating movement along the axis of the placement groove 22, thereby realizing the stirring of the whole blood cells in the reagent tube.
