Description
Technical Field
[0001] The utility model belongs to the technical field of hemodialysis fluid, and particularly relates to a sample placing rack for hemodialysis fluid. Background Technique
[0002] Hemodialysis fluid is a liquid that exchanges solutes with blood through diffusion on both sides of the dialysis membrane during hemodialysis. Hemodialysis fluid samples usually refer to liquid samples used during hemodialysis, and these samples can be used to detect the quality of the dialysis fluid, such as checking for the presence of bacteria or other contaminants. To sum up, the problems existing in the prior art are as follows: A sample placing rack for hemodialysis fluid is a device specifically used for storing hemodialysis fluid samples. It usually includes components such as a frame, a placing plate, and a partition plate. When in use, the sample tube is directly placed in the tube slot inside the frame cavity, and usually no limiting is done. The volume of the sample placing rack for hemodialysis fluid is relatively small, and it is usually directly carried by manpower when moving. If it accidentally drops, it is easy to cause the sample tube to fall to the ground and break, which is not only dangerous but also makes the sample unusable. However, the existing sample placing racks for hemodialysis fluid do not have components for more stable storage of the sample tubes. Therefore, a sample placing rack for hemodialysis fluid is specifically proposed to solve the above problems. Content of the Utility Model
[0003] In view of the problems existing in the prior art, the utility model provides a sample placing rack for hemodialysis fluid, which has the advantage of enabling the sample placing rack for hemodialysis fluid to store the sample tubes more stably, and solves the problems that the existing sample placing rack for hemodialysis fluid is a device specifically used for storing hemodialysis fluid samples. It usually includes components such as a frame, a placing plate, and a partition plate. When in use, the sample tube is directly placed in the tube slot inside the frame cavity, and usually no limiting is done. The volume of the sample placing rack for hemodialysis fluid is relatively small, and it is usually directly carried by manpower when moving. If it accidentally drops, it is easy to cause the sample tube to fall to the ground and break, which is not only dangerous but also makes the sample unusable. However, the existing sample placing racks for hemodialysis fluid do not have components for more stable storage of the sample tubes.
[0004] The utility model is realized as follows: A sample placing rack for hemodialysis fluid includes a frame and two device slots. The device slots are opened at the top of the frame. A number of sample tubes are movably connected inside the frame cavity. A limiting frame is arranged at the top of the frame. Two device shells that cooperate with the device slots are fixedly connected to the bottom of the limiting frame. The surface of the device shell is in contact with the inner cavity of the device slot. An extrusion control frame is movably connected inside the device shell. One side of the extrusion control frame away from the frame penetrates through the device shell and extends to the outside of the inner cavity of the device shell. A limiting device is arranged inside the device shell.
[0005] Preferably, the limiting device includes two limiting blocks. A moving hole is formed on the surface of the limiting block. A moving rod, which is fixedly connected to the inner cavity of the device housing and is used in cooperation with the moving hole, is movably connected to the inner cavity of the moving hole on the surface of the moving rod. A spring is fixedly connected to the opposite sides of the two limiting blocks. By providing the limiting device, when the limiting frame moves to the surface of the sample tube, the limiting device has a limiting effect on the position of the limiting frame.
[0006] Preferably, two extrusion rotating frames are movably connected to the inner cavity of the device housing through a rotating shaft. Extrusion columns, which are fixedly connected to the left and right sides of the limiting block and are used in cooperation with the extrusion rotating frames, are movably connected to the inner cavity of the extrusion rotating frames on the surface of the extrusion columns. The surface of the extrusion control frame contacts the surface of the extrusion rotating frame. By providing the extrusion rotating frame and the extrusion column, when the extrusion control frame moves, an extrusion force will be generated on the extrusion rotating frame. The extrusion rotating frame under the extrusion force will rotate along the surface of the extrusion column through the rotating shaft. The extrusion rotating frame can generate an extrusion force on the extrusion column, and the extrusion column under the extrusion force can drive the limiting block to move.
[0007] Preferably, limiting grooves, which are used in cooperation with the limiting blocks, are formed on the front and rear sides of the inner cavity of the device groove. The surface of the limiting block contacts the inner cavity of the limiting groove. By providing the limiting groove, when the device housing moves into the inner cavity of the device groove and the extrusion control frame is released, the restoring force generated by the spring restoring its shape will drive the limiting block to snap into the inner cavity of the limiting groove. The cooperation between the limiting block and the limiting groove has a limiting effect on the position of the device housing.
[0008] Preferably, an inner housing is fixedly connected to the bottom of the extrusion control frame. An outer housing is movably connected to the surface of the inner housing. The bottom of the outer housing is fixedly connected to the surface of the device housing. By providing the inner housing and the outer housing, when the extrusion control frame moves, it will drive the outer housing to move along the surface of the inner housing. The configuration and use of the inner housing and the outer housing have a limiting effect on the moving position of the extrusion control frame.
[0009] Preferably, four docking rods are fixedly connected to the bottom of the limiting frame. Four docking grooves, which are used in cooperation with the docking rods, are formed on the top of the frame. The surface of the docking rod contacts the inner cavity of the docking groove. By providing the docking rod and the docking groove, when the limiting frame moves, it will drive the docking rod to move into the inner cavity of the docking groove. The cooperation between the docking rod and the docking groove has a limiting effect on the moving position of the limiting frame.
[0010] Preferably, four anti-collision pads are fixedly connected to the inner cavity of the frame. The material of the anti-collision pad is foam cotton. By providing the anti-collision pad, when the frame accidentally falls to the ground, the anti-collision pad can protect the sample tube and prevent the sample tube from breaking.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. By using the cooperation of a limiting device, a limiting block, a moving hole, a moving rod and a spring, the present utility model solves the problem that the existing blood dialysis fluid sample placement rack is a device specifically used for storing blood dialysis fluid samples. It usually includes components such as a frame, a placement plate and a partition plate. When in use, the sample tube is directly placed in the tube slot inside the frame. Usually, there is no limit. The volume of the blood dialysis fluid sample placement rack is small, and it is usually directly carried by manpower when moving. If it accidentally falls, it is easy to cause the sample tube to fall to the ground and break, which is not only dangerous, but also makes the sample unusable. However, the existing sample placement rack for blood dialysis fluid does not have components for more stable storage of the sample tube.
[0013] 2. By setting the limiting device, the extrusion column under extrusion force will drive the two limiting blocks to move towards each other. When the limiting block moves, it will drive the moving hole to move along the surface of the moving rod. When the force generated by the movement of the limiting block causes the spring to undergo elastic deformation, the restoring force generated when the spring returns to its shape will drive the limiting block to snap into the inner cavity of the limiting groove. The limiting device has a limiting effect on the position of the limiting frame. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] In order to further understand the content, features and effects of the present utility model, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings.
[0020] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.
[0021] As Figures 1 to 4 shown, a sample placement rack for hemodialysis fluid provided by an embodiment of the present utility model includes a frame 1 and two device slots 2. The device slots 2 are opened at the top of the frame 1. A plurality of sample tubes 3 are movably connected in the inner cavity of the frame 1. A limit frame 4 is arranged at the top of the frame 1. Two device shells 5 that cooperate with the device slots 2 are fixedly connected to the bottom of the limit frame 4. The surface of the device shell 5 is in contact with the inner cavity of the device slot 2. An extrusion control frame 6 is movably connected in the inner cavity of the device shell 5. One side of the extrusion control frame 6 away from the frame 1 penetrates through the device shell 5 and extends to the outside of the inner cavity of the device shell 5. A limit device 7 is arranged in the inner cavity of the device shell 5.
[0022] Referring Figure 4 to
[0023] the above solution, by arranging the limit device 7, when the limit frame 4 moves to the surface of the sample tube 3, the limit device 7 has a limiting effect on the position of the limit frame 4.
[0024] Referring Figure 4 to
[0025] the above solution, by arranging the extrusion rotating frame 8 and the extrusion column 9, when the extrusion control frame 6 moves, it will generate an extrusion force on the extrusion rotating frame 8. The extrusion rotating frame 8 subjected to the extrusion force will rotate along the surface of the extrusion column 9 through the rotating shaft. The extrusion rotating frame 8 can generate an extrusion force on the extrusion column 9, and the extrusion column 9 subjected to the extrusion force can drive the limit block 701 to move.
[0026] Referring Figure 2 to
[0027] Adopting the above solution: By setting the limit groove 10, when the device housing 5 moves into the inner cavity of the device slot 2 and the extrusion control frame 6 is released, the restoring force generated by the spring 704 resuming its shape will drive the limit block 701 to snap into the inner cavity of the limit groove 10. The cooperation of the limit block 701 and the limit groove 10 has a limiting effect on the position of the device housing 5.
[0028] Reference Figure 3 , a inner housing 11 is fixedly connected to the bottom of the extrusion control frame 6. An outer housing 12 is movably connected to the surface of the inner housing 11. The bottom of the outer housing 12 is fixedly connected to the surface of the device housing 5.
[0029] Adopting the above solution: By setting the inner housing 11 and the outer housing 12, when the extrusion control frame 6 moves, it will drive the outer housing 12 to move along the surface of the inner housing 11. The configuration and use of the inner housing 11 and the outer housing 12 have a limiting effect on the moving position of the extrusion control frame 6.
[0030] Reference Figure 2 , four docking rods 13 are fixedly connected to the bottom of the limit frame 4. Four docking grooves 14 that cooperate with the docking rods 13 are opened at the top of the frame 1. The surface of the docking rod 13 is in contact with the inner cavity of the docking groove 14.
[0031] Adopting the above solution: By setting the docking rod 13 and the docking groove 14, when the limit frame 4 moves, it will drive the docking rod 13 to move into the inner cavity of the docking groove 14. The cooperation of the docking rod 13 and the docking groove 14 has a limiting effect on the moving position of the limit frame 4.
[0032] Reference Figure 2 , four anti-collision pads 15 are fixedly connected to the inner cavity of the frame 1. The anti-collision pads 15 are made of foam cotton.
[0033] Adopting the above solution: By setting the anti-collision pads 15, the anti-collision pads 15 can protect the sample tube 3 when the frame 1 accidentally drops to the ground, preventing the sample tube 3 from breaking.
[0034] The working principle of the present utility model:
[0035] During use, when the sample rack for hemodialysis fluid needs to store the sample tube 3 more stably, first, the user places the sample tube 3 in the inner cavity of the frame 1, and then pulls the extrusion control frame 6 downward. When the extrusion control frame 6 moves, it will drive the inner shell 11 to move downward along the inner cavity of the outer shell 12. When the extrusion control frame 6 moves, it will exert an extrusion force on the extrusion rotating frame 8. The extrusion rotating frame 8 under the extrusion force will drive the surface of the extrusion column 9 to rotate through the rotating shaft. The extrusion column 9 under the extrusion force will drive the two limiting blocks 701 to move towards each other. When the limiting blocks 701 move, they will drive the moving holes 702 to move along the surface of the moving rod 703. The force generated when the limiting blocks 701 move causes the spring 704 to undergo elastic deformation. When the limiting blocks 701 completely move into the inner cavity of the device shell 5, the limiting frame 4 is moved to the surface of the sample tube 3, and at the same time, the docking rod 13 is driven to move into the inner cavity of the docking groove 14. Then, the extrusion control frame 6 can be released. The restoring force generated when the spring 704 resumes its shape will drive the limiting blocks 701 to snap into the inner cavity of the limiting groove 10. The cooperation of the limiting blocks 701 and the limiting groove 10 restricts the positions of the device shell 5 and the limiting frame 4. When the sample rack accidentally falls to the ground, the limiting frame 4 restricts the position of the sample tube 3 to prevent the sample tube 3 from falling. At the same time, the anti-collision pad 15 can protect the sample tube 3. At this time, the sample rack for hemodialysis fluid needs to store the sample tube 3 more stably.
[0036] In summary: For the sample rack for hemodialysis fluid, by setting the limiting device 7, the limiting blocks 701, the moving holes 702, the moving rods 703 and the springs 704 to cooperate with each other, it solves the problem that the existing sample rack for hemodialysis fluid is a device specifically used for storing samples of hemodialysis fluid. It usually includes components such as a frame, a placement plate and a partition plate. During use, the sample tube is directly placed in the tube slot in the inner cavity of the frame, and usually no limiting is done. The volume of the sample rack for hemodialysis fluid is small, and it is usually carried manually when moving. If it accidentally falls, it is easy to cause the sample tube to fall to the ground and break, which is not only dangerous but also makes the sample unusable. However, the existing sample rack for hemodialysis fluid does not have components for storing the sample tube more stably.
