Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a sample disk of a biochemical analyzer. Background Art

[0002] A biochemical analyzer is a device that can complete some or all of the steps in biochemical analysis, such as sampling, adding reagents, removing interfering substances, mixing, incubating, colorimetric determination, result calculation, report writing, and cleaning, by imitating manual operations. It can perform analytical determinations of various reaction types, such as timing methods and continuous monitoring methods. In addition to the determination of general biochemical items, some can also perform the determination of special compounds such as hormones, immunoglobulins, and blood drug concentrations, as well as the application of analytical methods such as enzyme immunoassay and fluorescence immunoassay. It has the characteristics of being fast, simple, sensitive, accurate, standardized, and microscale. Generally, a biochemical analyzer will be provided with a sample disk to facilitate the storage of samples.

[0003] For example, Chinese patent document CN209356514U discloses a sample disk of a biochemical analyzer, which includes a disk body. Four reagent placement grooves are arranged at equal intervals in the horizontal direction on the top of the disk body. A discharge through hole is opened at the bottom of the reagent placement groove. A discharge pipe is fixedly connected to the inner wall of the discharge through hole. A sealing plug is threadedly installed at the bottom of the discharge pipe. A support rod is welded on the top of the disk body. An installation block is fixedly connected to the top of the support rod. A vertically arranged lead screw is threadedly installed on the installation block. A cylindrical rod is fixedly connected to the bottom of the lead screw. The cylindrical rod is located in the reagent placement groove. A current limiting block is fixedly connected to the bottom of the cylindrical rod. The bottom of the current limiting block presses against the top of the discharge through hole. A support column is fixedly connected to the bottom of the disk body. A bottom plate is fixedly connected to the bottom of the support column. The utility model realizes sampling according to demand, can accurately control the sampling amount, avoids waste of samples, and is easy to promote.

[0004] The following problems exist in the prior art:

[0005] When the prior art measures the sample volume, the current limiting block is driven to move by a threaded rod to control the sample entering the discharge pipe. However, when blocking or unblocking the discharge pipe, the current limiting block will generate multi-directional friction with the discharge pipe, reducing the service life of the current limiting block. At the same time, when the prior art receives the sample discharged from the discharge pipe, there is no support, and the height of the bottom plate from the discharge pipe is not adjustable. It is necessary for the staff to hold the container to receive the sample, and at the same time, it is necessary for the staff to remove the sealing plug. This causes the container held by the staff to tilt, resulting in sample loss and reducing the practicality of the device. Summary of the Utility Model

[0006] The utility model provides a sample disk of a biochemical analyzer to solve the problems raised in the above background art.

[0007] To solve the above technical problems, the technical solution adopted by the present utility model is as follows:

[0008] A sample disk for a biochemical analyzer, comprising a support plate. At the four corners of the top of the support plate, support legs are fixedly connected. At the top of the support legs, a sample disk is fixedly connected. At the top of the sample disk, support frames are fixedly connected in a linear array. An adjusting mechanism is inserted into the inner wall of the support legs. At the top of the support frames, a current-limiting mechanism is rotatably connected. The adjusting mechanism includes a plug rod, and the outer wall of the plug rod is inserted into the inner wall of the support legs. The current-limiting mechanism includes a rotating rod, and the top of the rotating rod is rotatably connected to the top of the support frames.

[0009] Preferably: A connecting plate is inserted on the outer wall of the plug rod, and the outer wall of the connecting plate is slidably connected to the outer wall of the support legs. On one side of the plug rod near the end, a spring is fixedly connected, and one end of the spring is fixedly connected to the outer wall of the connecting plate.

[0010] Preferably: A receiving plate is fixedly connected to the outer wall of the connecting plate, and the outer wall of the receiving plate is slidably connected to the outer wall of the support legs. At the front and rear parts of the left and right ends of the receiving plate, limiting blocks are fixedly connected. The outer walls of the limiting blocks are slidably connected to the inner wall of the support legs, and the shape of the limiting blocks is T-shaped.

[0011] Preferably: A limiting ring is fixedly connected to the top of the rotating rod, and the outer wall of the limiting ring is rotatably connected to the top of the support frames.

[0012] Preferably: A movable plate is fixedly connected to the bottom end of the rotating rod, and a metering tube is slidably connected to the outer wall of the movable plate. The top of the metering tube is fixedly connected to the bottom of the sample disk. Scales are provided on the outer wall of the metering tube, and a sealing plug is threadedly connected to the bottom of the scales.

[0013] Preferably: Four through holes I are provided in a circular array on the outer wall of the movable plate. At the bottom end of the movable plate, four positioning blocks are fixedly connected in a circular array. The positioning blocks are made of rubber. The bottom end of the movable plate is rotatably connected to a fixing plate, and the inner wall of the fixing plate is clamped with the outer wall of the positioning blocks. The outer wall of the fixing plate is fixedly connected to the inner wall of the metering tube. Four through holes II are provided in a circular array on the outer wall of the fixing plate, and the size of the through holes II is larger than that of the through holes I.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is as follows:

[0015] 1. The utility model provides a sample tray for a biochemical analyzer. By pulling the insertion rod, the insertion rod drives the spring to stretch, so that the outer wall of the insertion rod no longer plugs into the inner wall of the receiving plate. Subsequently, the receiving plate can be pulled to perform vertical translation, thereby changing the height between the receiving plate and the bottom end of the metering tube. When the height is appropriate, the insertion rod can be released, and the outer wall of the insertion rod plugs into the inner wall of the support leg again, achieving the effect of adjusting the height of the receiving plate.

[0016] 2. The utility model provides a sample tray for a biochemical analyzer. By rotating the rotating rod, the rotating rod drives the limiting ring to rotate inside the inner wall of the support frame. The limiting ring limits the rotating rod, so that the rotating rod can only rotate and cannot move up and down. At the same time, the rotating rod drives the movable plate to rotate, and the movable plate drives the positioning block to rotate synchronously, so that the outer wall of the positioning block no longer engages with the inner wall of the fixed plate. As a result, the first through hole and the second through hole gradually overlap, and the sample in the sample tray flows into the metering tube. The amount flowing into the metering tube is observed through the scale. When it is sufficient, the rotating rod is rotated to drive the movable plate to rotate synchronously. When the outer wall of the positioning block plugs into the inner wall of the fixed plate again, a certain resistance will be generated. At this time, the rotation of the rotating rod can be stopped. At this time, the movable plate has blocked the second through hole again, so that the sample cannot flow into the metering tube. Subsequently, the sealing plug can be removed, and the sample in the metering tube falls into the container, achieving the effect of controlling the sample taking amount.

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0025] As Figures 1-4 shown, a sample tray of a biochemical analyzer includes a support plate 1. Support legs 11 are fixedly connected to the four corners of the top end of the support plate 1. The top ends of the support legs 11 are fixedly connected to a sample tray 12. Support frames 13 are fixedly connected to the top of the sample tray 12 in a linear array. An adjusting mechanism 2 is inserted into the inner wall of the support leg 11. A flow-limiting mechanism 3 is rotatably connected to the top of the support frame 13. The adjusting mechanism 2 includes a plug rod 21. The outer wall of the plug rod 21 is inserted into the inner wall of the support leg 11. The flow-limiting mechanism 3 includes a rotating rod 31. The top of the rotating rod 31 is rotatably connected to the top of the support frame 13.

[0026] By changing the distance between the bearing plate 24 and the measuring tube 35 through the adjusting mechanism 2, and then controlling the amount of the sampled sample through the flow-limiting mechanism 3.

[0027] As Figure 2 、 Figure 3 shown, a connecting plate 23 is inserted on the outer wall of the plug rod 21. The outer wall of the connecting plate 23 is slidably connected to the outer wall of the support leg 11. A spring 22 is fixedly connected to one side of the plug rod 21 close to the end. One end of the spring 22 is fixedly connected to the outer wall of the connecting plate 23. A bearing plate 24 is fixedly connected to the outer wall of the connecting plate 23. The outer wall of the bearing plate 24 is slidably connected to the outer wall of the support leg 11. Limiting blocks 25 are fixedly connected to the front and rear parts of the left and right ends of the bearing plate 24. The outer wall of the limiting block 25 is slidably connected to the inner wall of the support leg 11. The shape of the limiting block 25 is T-shaped.

[0028] By pulling the insertion rod 21, the insertion rod 21 drives the spring 22 to stretch, so that the outer wall of the insertion rod 21 is no longer inserted into the inner wall of the receiving plate 24. Subsequently, the receiving plate 24 can be pulled to make the receiving plate 24 translate in the vertical direction. The receiving plate 24 drives the limiting block 25 to slide synchronously on the inner wall of the support leg 11. The limiting block 25 limits and guides the receiving plate 24, making the receiving plate 24 move more smoothly, thereby changing the height between the receiving plate 24 and the bottom end of the metering tube 35. When the height is appropriate, the insertion rod 21 can be released. Under the action of the elastic force of the spring 22, the outer wall of the insertion rod 21 is inserted into the inner wall of the support leg 11 again, thereby limiting the receiving plate 24 and making the receiving plate 24 unable to move, which is convenient for obtaining samples with utensils subsequently and achieves the effect of adjusting the height of the receiving plate 24.

[0029] As Figure 2 , Figure 4 shown, a limiting ring 311 is fixedly connected to the top of the rotating rod 31, and the outer wall of the limiting ring 311 is rotatably connected to the top of the support frame 13.

[0030] By rotating the rotating rod 31, the rotating rod 31 drives the limiting ring 311 to rotate on the inner wall of the support frame 13. The limiting ring 311 limits the rotating rod 31, making the rotating rod 31 only able to rotate and unable to move up and down.

[0031] As Figure 2 , Figure 4 shown, a movable plate 32 is fixedly connected to the bottom end of the rotating rod 31. The outer wall of the movable plate 32 is slidably connected to a metering tube 35. The top of the metering tube 35 is fixedly connected to the bottom of the sample tray 12. A scale 36 is provided on the outer wall of the metering tube 35, and a sealing plug 37 is threadedly connected to the bottom of the scale 36.

[0032] Observe the amount flowing into the metering tube 35 through the scale 36. When it is sufficient, rotate the rotating rod 31 to drive the movable plate 32 to rotate synchronously. When the outer wall of the positioning block 33 is inserted into the inner wall of the fixed plate 34 again, a certain resistance will be generated. At this time, the rotation of the rotating rod 31 can be stopped. At this time, the movable plate 32 has blocked the through hole two 341 again, making the sample unable to flow into the metering tube 35. Subsequently, the sealing plug 37 can be removed, and the sample in the metering tube 35 falls into the utensil.

[0033] As Figures 4-6 shown, four through holes one 321 are provided on the outer wall of the movable plate 32 in a circular array. Four positioning blocks 33 are fixedly connected to the bottom end of the movable plate 32 in a circular array. The positioning blocks 33 are made of rubber. The bottom end of the movable plate 32 is rotatably connected to a fixed plate 34. The inner wall of the fixed plate 34 is clamped with the outer wall of the positioning block 33. The outer wall of the fixed plate 34 is fixedly connected to the inner wall of the metering tube 35. Four through holes two 341 are provided on the outer wall of the fixed plate 34 in a circular array, and the size of the through hole two 341 is larger than the size of the through hole one 321.

[0034] When the rotating rod 31 rotates, it drives the movable plate 32 to rotate, causing the movable plate 32 to drive the positioning block 33 to rotate synchronously, so that the outer wall of the positioning block 33 is no longer engaged with the inner wall of the fixed plate 34. Thus, the first through hole 321 and the second through hole 341 gradually overlap, and the sample in the sample tray 12 flows into the metering tube 35.

[0035] The working principle of the present utility model: During use, different samples are respectively placed into the sample tray 12. Then, according to requirements, the required sample is obtained. First, the receiving plate 24 is adjusted to a suitable height according to the size of the container. The insertion rod 21 is pulled, causing the insertion rod 21 to drive the spring 22 to stretch, so that the outer wall of the insertion rod 21 is no longer inserted into the inner wall of the receiving plate 24. Subsequently, the receiving plate 24 can be pulled, causing the receiving plate 24 to perform a vertical translation. The receiving plate 24 drives the limiting block 25 to slide synchronously on the inner wall of the support leg 11. The limiting block 25 limits and guides the receiving plate 24, making the movement of the receiving plate 24 smoother. In this way, the height between the receiving plate 24 and the bottom end of the metering tube 35 is changed. When the height is appropriate, the insertion rod 21 can be released. Under the elastic force of the spring 22, the outer wall of the insertion rod 21 is inserted into the inner wall of the support leg 11 again, thereby limiting the receiving plate 24 and preventing the receiving plate 24 from moving. This facilitates obtaining the sample with a container later and achieves the effect of adjusting the height of the receiving plate 24. Subsequently, the container is placed directly below the metering tube 35. Then, according to the required amount of the sample, the rotating rod 31 is rotated, causing the rotating rod 31 to drive the limiting ring 311 to rotate on the inner wall of the support frame 13. The limiting ring 311 limits the rotating rod 31, making the rotating rod 31 only able to rotate and not move up and down. At the same time, the rotating rod 31 drives the movable plate 32 to rotate, causing the movable plate 32 to drive the positioning block 33 to rotate synchronously, so that the outer wall of the positioning block 33 is no longer engaged with the inner wall of the fixed plate 34. Thus, the first through hole 321 and the second through hole 341 gradually overlap, and the sample in the sample tray 12 flows into the metering tube 35. The amount flowing into the metering tube 35 is observed through the scale 36. When it is sufficient, the rotating rod 31 is rotated, driving the movable plate 32 to rotate synchronously. When the outer wall of the positioning block 33 is inserted into the inner wall of the fixed plate 34 again, a certain resistance will be generated. At this time, the rotation of the rotating rod 31 can be stopped. At this time, the movable plate 32 has blocked the second through hole 341 again, preventing the sample from flowing into the metering tube 35. Subsequently, the sealing plug 37 can be removed, and the sample in the metering tube 35 falls into the container, achieving the effect of controlling the sample taking amount. This greatly improves the use experience.
