Description

Technical Field

[0001] The utility model belongs to the technical field of blood cell analyzers, and specifically relates to an internal reagent storage device of a blood cell analyzer. Background Art

[0002] In the field of medical diagnosis, blood cell analyzers are indispensable equipment that provide doctors with key information about the patient's health status through automatic analysis of blood samples. These analyzers usually rely on precise reagents to perform various chemical reactions and biological analyses to obtain accurate diagnostic results.

[0003] Existing reagent storage devices inside blood cell analyzers mostly use simple physical structures, such as simple containers or drawers, for storing reagents. When in use, the container is opened and then installed inside the blood cell analyzer. When in use, blood and the solution inside the reagent are extracted to perform reaction detection.

[0004] However, the container needs to be opened when using it. If there are multiple groups of solutions used at the same time, when the first group is used, the subsequent containers are in an open state. It cannot effectively prevent the reagents from being contaminated by the external environment, such as dust, bacteria or other impurities, resulting in reduced detection accuracy during subsequent use.

[0005] To this end, we proposed an internal reagent storage device for a blood cell analyzer, which can ensure the purity and safety of the reagents. Utility Model Content

[0006] The purpose of the present invention is to provide an internal reagent storage device for a blood cell analyzer, which can ensure the purity and safety of the reagents.

[0007] The technical solutions adopted in this utility are as follows:

[0008] A reagent storage device inside a blood cell analyzer, comprising a carrying shell and a cover, wherein an electric telescopic rod is installed on one side of the carrying shell, and a plurality of groups of carrying holes for carrying different reagents are provided on the carrying shell, and connecting plates are provided on both sides of the carrying shell, and each connecting plate is provided with a slide groove and a first magnet;

[0009] A telescopic rod connected to the outside world is arranged on the top of the cover body, a groove is opened on the cover body, a sealing cover matching the bearing hole is arranged inside the groove, an elastic component, a plurality of second magnets and a plurality of third magnets are arranged on the inner wall of the bottom of the cover body, the second magnets and the third magnets are alternately arranged on the cover body, the second magnets and the first magnets are attracted to each other, and the third magnets and the first magnets repel each other, the elastic component is arranged inside the slider, and the slider is arranged inside the slide groove.

[0010] Furthermore, an identification card is provided on the carrying shell.

[0011] Furthermore, the width of the groove is the same as the width of the bearing shell.

[0012] Furthermore, the thrust of the electric telescopic rod is greater than the suction force of the first magnet and the second magnet.

[0013] Furthermore, the elastic component includes a through hole opened inside the slider, a hollow cylinder is arranged inside the through hole, a spring is arranged inside the hollow cylinder, a piston disk is arranged on the top of the spring, a connecting rod is installed on the top of the piston disk, and the top of the connecting rod passes through the hollow cylinder and is connected to the cover body.

[0014] Furthermore, the slide groove matches the slide block.

[0015] The technical effects achieved by this utility model are:

[0016] When the device is not in use, the first magnet on the bearing shell and the second magnet on the cover body attract each other, causing the cover body to move downward with the assistance of the elastic component, thereby ensuring that the sealing cover tightly seals the bearing hole to prevent the reagent from being contaminated by external impurities and dust. When the reagent is needed, the electric telescopic rod is started to drive the bearing shell to move. During this process, the slider moves smoothly in the slide groove, separating the first magnet from the second magnet. At this time, the first magnet and the third magnet generate a repulsive force, which drives the cover body to move upward through the elastic component, so that the bearing hole is completely exposed, which is convenient for the use of the reagent. Since the second magnet and the third magnet are staggered on the cover body, when the bearing shell continues to move, the first magnet will attract the second magnet again, repeating the above sealing process to ensure that the unused reagent continues to be protected. The device ensures the purity and safety of the reagent. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0025] like Figure 1-5 As shown, the technical solution adopted by the utility model is specifically as follows: a reagent storage device inside a blood cell analyzer, comprising a carrying shell 1 and a cover 2, an electric telescopic rod 3 is installed on one side of the carrying shell 1, a plurality of groups of carrying holes 4 for carrying different reagents are provided on the carrying shell 1, connecting plates 5 are provided on both sides of the carrying shell 1, and each connecting plate 5 is provided with a slide groove 6 and a first magnet 7;

[0026] The top of the cover 2 is provided with a telescopic rod 8 connected to the outside world. The function of the telescopic rod 8 is to drive the telescopic rod 8 to move up and down when the cover 2 moves up and down, which can not only achieve the effect of movement, but also achieve the effect of fixing the position.

[0027] A groove 9 is provided on the cover body 2, and a sealing cover 10 matching the bearing hole 4 is arranged inside the groove 9. An elastic component, a plurality of second magnets 11 and a plurality of third magnets 12 are arranged on the inner wall of the bottom of the cover body 2. The second magnets 11 and the third magnets 12 are alternately arranged on the cover body 2, the second magnets 11 and the first magnets 7 are attracted to each other, and the third magnets 12 and the first magnets 7 are repelled from each other. The elastic component is arranged inside the slider 13, and the slider 13 is arranged inside the slide groove 6.

[0028] Its working principle is as follows: first, different reagents are carried by multiple groups of bearing holes 4 on the bearing shell 1. When the device is not in use, the first magnet 7 on the bearing shell 1 and the second magnet 11 on the cover body 2 attract each other, so that the cover body 2 moves down with the assistance of the elastic component, thereby ensuring that the sealing cover 10 tightly seals the bearing hole 4 to prevent the reagent from being contaminated by external impurities and dust. When the reagent needs to be used, the electric telescopic rod 3 is started to drive the bearing shell 1 to move. In this process, the slider 13 moves smoothly in the slide groove 6 to separate the first magnet 7 from the second magnet 11. At this time, the first magnet 7 and the third magnet 12 generate a repulsive force, which drives the cover body 2 to move up through the elastic component, so that the bearing hole 4 is completely exposed, which is convenient for the use of the reagent. Since the second magnet 11 and the third magnet 12 are staggered on the cover body 2, when the bearing shell 1 continues to move, the first magnet 7 will attract the second magnet 11 again, repeating the above-mentioned sealing process to ensure that the unused reagent continues to be protected. The device ensures the purity and safety of the reagent.

[0029] The bearing shell 1 is slidably mounted on the outside, and the sliding movement here can be achieved by setting the sliding groove 6.

[0030] Meanwhile, the electric telescopic rod 3 is installed inside the blood cell analyzer, and is driven by electricity. The working principle of the electric telescopic rod 3 belongs to the prior art and will not be described in detail here.

[0031] In the prior art, the internal reagents of the blood cell analyzer play a vital role in the blood analysis process. These reagents mainly include diluent, hemolytic agent and cleaning solution. The main function of the diluent is to maintain the osmotic pressure of blood cells stable and prevent the volume and shape of cells from changing, so as to ensure that the blood cell analyzer can obtain more accurate data. The main function of the hemolytic agent is to dissolve the cell membrane of red blood cells and make the cytoplasm flow out, so that the instrument can measure the hemoglobin content according to the depth of color. The main responsibility of the cleaning solution is to clean the blood and various proteins in the instrument pipeline, reduce the cross contamination of blood, and ensure the reliability and accuracy of the results.

[0032] The utility model arranges three bearing holes 4 as a group, and each group of bearing holes 4 is provided with diluent, hemolytic agent and cleaning liquid for subsequent extraction by an extraction needle. At the same time, such an arrangement can better distinguish and avoid confusion.

[0033] In order to further distinguish them better, an identification card is provided on the carrying shell 1, which can facilitate people to distinguish them.

[0034] The width of the groove 9 is the same as the width of the bearing housing 1 , and such an arrangement enables the sealing cover 10 to correspond to the position of the bearing hole 4 , thereby ensuring the subsequent work to proceed.

[0035] It should be noted that the thrust of the electric telescopic rod 3 is greater than the suction force of the first magnet 7 and the second magnet 11. This arrangement can generate thrust on the electric telescopic rod 3, and the first magnet 7 and the second magnet 11 can be quickly separated without causing subsequent interference.

[0036] like Figure 5 As shown, the elastic component includes a through hole opened inside the slider 13, a hollow cylinder 14 is arranged inside the through hole, a spring 15 is arranged inside the hollow cylinder 14, a piston disk 16 is arranged on the top of the spring 15, a connecting rod 17 is installed on the top of the piston disk 16, and the top of the connecting rod 17 passes through the hollow cylinder 14 and is connected to the cover body 2.

[0037] When the cover body 2 moves up or down due to repulsion or suction, it drives the connecting rod 17 to make the piston disc 16 squeeze the spring 15 or move up and down through the elastic force of the spring 15, thereby performing the sealing and opening operations.

[0038] The slide groove 6 matches the slider 13 , which means that when the bearing shell 1 moves, the slide groove 6 and the slider 13 can slide, so that the sliding is smooth.

[0039] The working principle of the utility model is as follows: first, different reagents are carried by multiple groups of bearing holes 4 on the bearing shell 1. When the device is not in use, the first magnet 7 on the bearing shell 1 and the second magnet 11 on the cover body 2 attract each other, so that the cover body 2 moves down with the assistance of the elastic component, thereby ensuring that the sealing cover 10 tightly seals the bearing hole 4 to prevent the reagent from being contaminated by external impurities and dust. When the reagent needs to be used, the electric telescopic rod 3 is started to drive the bearing shell 1 to move. In this process, the slider 13 moves smoothly in the slide groove 6 to separate the first magnet 7 from the second magnet 11. At this time, the first magnet 7 and the third magnet 12 generate a repulsive force, which drives the cover body 2 to move up through the elastic component, so that the bearing hole 4 is completely exposed, which is convenient for the use of the reagent. Since the second magnet 11 and the third magnet 12 are staggered on the cover body 2, when the bearing shell 1 continues to move, the first magnet 7 will attract the second magnet 11 again, repeating the above-mentioned sealing process to ensure that the unused reagent continues to be protected. The device ensures the purity and safety of the reagent.

[0040] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
