DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0037] Reference Figure 1-Figure 11A cardiology blood sampling and testing device comprises: a sample placement box 1, a top cover 10 fixedly mounted on the upper end of the sample placement box 1, a centrifuge 2 mounted inside the sample placement box 1, and a sampling device 3 fixed on the side of the sample placement box 1, wherein one half of the top cover 10 is configured as a rotating plate, and the other half is configured as a mounting plate, and a mounting opening is provided on the mounting plate;

[0038] The sampling device 3 includes a sampling end 31 and a sampling tube 32. The sampling tube 32 is installed at the bottom of the sampling end 31 and is located directly above the installation port. An internal flushing component 4 is provided inside the sampling end 31. The internal flushing component 4 is used to clean the inside of the sampling tube 32.

[0039] The internal flushing assembly 4 includes a cleaning rod 41, a scraping ring 42 and a plurality of nozzles 43. The cleaning rod 41 is telescopically slidably arranged inside the sampling end 31, and the plurality of nozzles 43 are annularly fixedly installed at one end of the cleaning rod 41 close to the sampling tube 32. The scraping ring 42 is fixedly connected to one end of the cleaning rod 41 close to the sampling tube 32.

[0040] A sealing component 5 is disposed inside the installation port, and a recoil component 6 is disposed inside the sealing component 5. The sealing component 5 is used to provide a sealed environment for the sampling tube 32, and the recoil component 6 is used to clean the outside of the sampling tube 32 in the sealed environment.

[0041] In the embodiment of the application of the above technical solution, during the sampling and detection process, the sampling device 3 is controlled to extract the sample inside the sample placement box 1. When the extraction is completed, the sampling tube 32 that has completed the sampling is transferred to the inside of the sealing component 5. At this time, the inner wall of the sampling tube 32 is flushed by controlling multiple nozzles 43. While flushing, the cleaning rod 41 is controlled to move inside the sampling tube 32. The scraper ring 42 at the end of the cleaning rod 41 scrapes and cleans the inner wall of the sampling tube 32, and the end of the sampling tube 32 is blocked. When the inside of the sampling tube 32 is cleaned, the outside of the sampling tube 32 is cleaned by the backflushing component 6. At the same time, the cleaning rod 41 prevents the waste liquid from re-entering the inside of the sampling tube 32 during the backflushing process, thereby ensuring the cleaning effect of the sampling tube 32.

[0042] The present invention can quickly clean the inner and outer walls of the sampling tube 32, thereby avoiding a large amount of sample remaining inside and outside the sampling tube 32 during the sampling process, and ensuring the accuracy of the detection.

[0043] The preferred technical solution in this embodiment is:

[0044] Reference Figure 4-6The centrifuge 2 comprises a rotating seat 21, a placement plate 22 and a plurality of clamping members 23. The rotating seat 21 is rotatably mounted inside the sample placement box 1. The placement plate 22 is fixedly sleeved on the rotating seat 21. The placement plate 22 is provided with a plurality of placement openings. The plurality of clamping members 23 are fixedly mounted inside the placement openings.

[0045] The sampling device 3 further comprises a fixing seat 33 and a control seat 34 . The fixing seat 33 is fixedly mounted on the side of the sample placement box 1 . The control seat 34 is fixedly mounted on the fixing seat 33 . The sampling end 31 is fixedly mounted on the control seat 34 .

[0046] The sample to be tested is placed in a sample tube or a sample cup, and the sample container is placed inside the clamp 23. The clamp 23 is controlled to rotate by the centrifugal device arranged inside the placement plate 22, so as to centrifuge the sample. The centrifugal force can make substances of different weights and densities settle or float in the sample container. Since the density of plasma is relatively low, it will float to the top layer of the centrifuge tube during the centrifugation process. However, due to its relatively high density, red blood cells will settle to the bottom of the centrifuge tube, thereby completing the separation of different components in the blood and facilitating the extraction and detection of different components.

[0047] During testing, the control seat 34 drives the sampling tube 32 to rotate and move up and down, so that the sample is extracted into the sampling tube 32 and then transferred to the testing equipment for testing. Through intelligent sampling, a large number of samples can be sampled and tested quickly, thereby improving the efficiency of testing.

[0048] Reference Figure 5-7 The internal flushing component 4 also includes a water tank 44, a water pipe 45 and a control module 46. The water tank 44 is fixedly installed at the bottom of the sampling end 31, the control module 46 is fixedly installed at the execution end of the sampling end 31, and the water pipe 45 is fixedly connected between the water tank 44 and the control module 46.

[0049] When flushing the inside of the sampling tube 32, the control module 46 controls the water pipe 45 to pump water from the inside of the water tank 44. The control module 46 has a control chip and a control valve inside, which are used to control the introduction of water, and introduce water into the nozzle 43 through the channel inside the cleaning rod 41, so as to clean the inside of the sampling tube 32 through the nozzle 43.

[0050] Reference Figure 6-9The sealing assembly 5 includes a sealing tube 51, a plurality of sliding rods 52, a plurality of clamping blocks 53 and a plurality of sealing blocks 54. The sealing tube 51 is fixedly installed inside the installation port. The sealing tube 51 is provided with ring openings on the upper and lower sides. A plurality of sliding openings are provided in an annular shape between the two ring openings. The sliding rod 52 is fixedly connected between the clamping block 53 and the sealing block 54 to form a sealing member. The plurality of sealing members are respectively slidably arranged inside the plurality of sliding openings to seal the upper and lower sides of the sealing tube 51.

[0051] The clamping block 53 is an arc-shaped block, and a plurality of the clamping blocks 53 form a clamping ring for clamping the sampling tube 32. The sealing block 54 is a fan-shaped block, and a plurality of the sealing blocks 54 form a sealing plate. The clamping block 53 and the sealing block 54 are slidably disposed inside the upper and lower ring openings, respectively.

[0052] A driving assembly 7 is provided at the upper end of the sealing tube 51, and the driving assembly 7 includes a shell 71, a plurality of driving rods 72, a plurality of telescopic rods 73 and a plurality of fixing rings 74. The shell 71 is fixedly installed on the upper end of the sealing tube 51, and the plurality of telescopic rods 73 are annularly fixedly connected to the inner side of the shell 71 and are horizontally arranged. The driving rod 72 is fixedly connected to the clamping block 53, and the fixing ring 74 is fixedly connected to the end of the telescopic rod 73 and is sleeved on the driving rod 72.

[0053] During the flushing and backwashing process, a large amount of cleaning liquid will be present inside the sealing tube 51. In order to prevent the cleaning liquid from leaking out, the upper and lower ends of the sealing tube 51 need to be sealed.

[0054] By controlling the synchronous extension and retraction of the multiple telescopic rods 73, the fixed ring 74 drives the driving rod 72 to move toward the center of the circle of the sealing tube 51. At this time, the clamping block 53 will slide inside the upper ring mouth, and at the same time, the lower sliding rod 52 will slide inside the sliding mouth, so that the multiple sealing blocks 54 below will also move toward the center of the circle. The multiple clamping blocks 53 form a clamping ring to clamp the upper part of the sampling tube 32 and seal the upper end of the sealing tube 51. The sealing plate formed by the multiple sealing blocks 54 seals the bottom end of the sealing tube 51 to prevent the outflow of cleaning liquid during the cleaning process.

[0055] Reference Figure 6-8 The recoil assembly 6 includes a plurality of recoil heads 61, a liquid guide ring 62 and a plurality of connecting tubes 63. A mounting hole is provided on the upper surface of the sealing block 54. The recoil head 61 is fixedly mounted inside the mounting hole. The liquid guide ring 62 is fixedly mounted at the bottom end of the sealing tube 51. The plurality of connecting tubes 63 are fixedly connected between the recoil head 61 and the liquid guide ring 62.

[0056] During the sampling process, both the inner and outer sides of the sampling tube 32 will come into contact with the sample. If the outer side of the sampling tube 32 is not cleaned, the residual sample will be mixed into the next sample, affecting the accuracy of the detection.

[0057] When multiple sealing blocks 54 form a sealing plate to seal the bottom of the sealing tube 51, the control valve inside the recoil head 61 sprays the cleaning liquid in the liquid guide ring 62, thereby forming a jet from bottom to top inside the sealing tube 51. Not only the waste liquid generated when cleaning the inside of the sampling tube 32 is sprayed upward to prevent the internal waste liquid from affecting the cleaning of the outer wall of the sampling tube 32, but also the cleaning liquid inside the sealing tube 51 can be quickly extracted by spraying upward, thereby reducing the residual cleaning liquid inside the sealing tube 51.

[0058] Reference Figure 7-10 A suction assembly 8 is provided at the upper end of the sealing tube 51. The suction assembly 8 is used to extract the cleaning liquid. The suction assembly 8 includes a liquid extraction ring 81, a liquid guide tube 82 and a liquid outlet pipe 83. The liquid extraction ring 81 is fixedly installed at the upper end of the sealing tube 51. A liquid extraction port is opened inside the clamping block 53. The liquid guide tube 82 is connected between the liquid extraction tube and the liquid extraction port. The liquid outlet pipe 83 is fixedly installed on the outside of the liquid extraction ring 81.

[0059] Since a large amount of cleaning liquid is used in the process of cleaning the inside and outside of the sampling tube 32, when the sealing tube 51 is in an unsealed state, the cleaning liquid is likely to flow out, causing the cleaning liquid to flow into the sample channel, affecting the sampling test results, and the generated cleaning liquid needs to be sucked out.

[0060] By setting a powerful fan suction machine on the outside (the fan suction machine belongs to the prior art and does not appear in the attached drawings of this device), the air suction port of the wind suction machine is connected to the liquid outlet pipe 83. When extracting, the large wind force generated outside is used to suck the cleaning liquid inside the sealing tube 51, and the generated waste liquid is sucked into the liquid extraction ring 81 through the liquid extraction port and the liquid guide tube 82 (the liquid guide tube 82 is elastic and can be extended, so as to ensure that the clamping block 53 can still be connected with the liquid extraction ring 81 through the liquid guide tube 82 during the sliding process) and then discharged through the liquid outlet pipe 83, thereby completing the extraction and discharge of the waste liquid inside the sealing tube 51 to avoid affecting the detection results.

[0061] Reference Fig.11 The bottom of the sealing tube 51 is provided with a bottom opening component 9, and the bottom opening component 9 is used to seal the bottom of the liquid guide ring 62;

[0062] The bottom port assembly 9 includes a plurality of sealing sheets 91 and a plurality of cleaning strips 92. The plurality of sealing sheets 91 are fixedly mounted on the bottom of the liquid guide ring 62. The plurality of cleaning strips 92 are fixedly connected to the upper surface of the sealing sheets 91. The cleaning strips are made of a water-absorbing material.

[0063] When the sealing tube 51 changes from a sealed state to an open state, a small amount of waste liquid that has not been completely extracted will drip from the inside of the sealing tube 51. The waste liquid is blocked by the bottom port assembly 9, and the bottom surface of the liquid guide ring 62 is set to a truncated cone shape, which can guide and collect the dripping waste liquid to avoid dripping of the waste liquid.

[0064] At the same time, after the sampling tube 32 is flushed, some water will remain on the outer wall of the sampling tube 32. When the sampling tube 32 moves downward under the control of the control seat 34, the sealing sheet 91 will be squeezed downward, so that the cleaning strip 92 contacts the side of the sampling tube 32, and the waste liquid on the side of the sampling tube 32 is absorbed by the cleaning strip 92. Similarly, after the sampling tube 32 is extracted, the sampling tube 32 will move upward, causing the cleaning strip 92 to contact the outer wall of the sampling tube 32 for cleaning, thereby improving the cleaning effect.

[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
