Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an analyzer. Background Technology

[0002] Analyzers (in vitro diagnostic medical devices) belong to the category of in vitro diagnostic reagents and instruments within medical devices. They refer to devices or systems that provide clinical diagnostic information by analyzing human samples (such as blood, urine, and tissues). Common types include biochemical analyzers, immunoassay analyzers, blood cell analyzers, and molecular diagnostic analyzers. An increasing number of analyzers are designed with structural improvements in mind, simplifying their design to achieve miniaturization and greater portability.

[0003] During analyzer testing, the sample to be tested needs to be protected from external light interference and to prevent uncertainties caused by human operation. Typically, the sample is placed in a designated area within the instrument for testing. To prevent contaminants from falling into the sample and contaminating it during testing, thus causing inaccurate results, a door is required to block light as the sample needs to enter and exit the analyzer. During continuous testing, the door needs to be opened and closed frequently. Utility Model Content

[0004] To address the aforementioned problems, an analyzer is provided, comprising: main body; The container is located on one side of the main body. The container contains a drive module, which is connected to a carrier. The carrier is used to load material racks. An opening is provided on the side of the container. Driven by the drive module, the carrier passes through the opening into the container. A door is installed on the container to cover the opening.

[0005] In one embodiment, the accommodating compartment includes a floor, to which the vehicle is slidably connected; and the door is pivotally connected to the floor.

[0006] In one embodiment, a resilient reset unit is connected between the hatch and the floor plate; When the reset unit is in a state of large deformation, the hatch is away from the opening; When the reset unit is in a small deformation state or a recovery state, the hatch covers the opening.

[0007] In one embodiment, driven by the drive module, the vehicle contacts the hatch and causes the hatch to rotate from the covered opening to a position away from the opening.

[0008] In one embodiment, the carrier includes a limiting track, a base plate, and a push block, with the limiting track and the push block respectively disposed on two surfaces of the base plate; The limiting track is slidably connected to the material rack, and the push block contacts the hatch.

[0009] In one embodiment, the carrier is provided with a slider, the slider and the push block are disposed on the same surface of the substrate, and a guide rail adapted to the slider is mounted on the base plate.

[0010] In one embodiment, the rack is provided with multiple sample compartments, which are distributed along a first straight line, and the drive vehicle of the drive module moves along the first straight line.

[0011] In one embodiment, a handle unit is provided on one end of the rack.

[0012] In one embodiment, a clearance groove is provided on one end of the material rack, so that the end of the material rack with the clearance groove forms a hook-shaped handle unit.

[0013] In one embodiment, a contact screen is mounted on one surface of the main body, and the hatch and the contact screen are located on the same side of the main body and the housing compartment.

[0014] The aforementioned analyzer, by having an opening in the housing chamber with a coverable door, allows for easy access for the material rack while simultaneously isolating the opening. Specifically, the opening is open when the material rack is being moved in or out, and closed at other times. This prevents external light sources from interfering with the internal test results during the detection process and effectively reduces the risk of dust entering the analyzer.

[0023] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0027] See Figure 1-3 As shown in some embodiments of this application, an analyzer includes a receiving chamber 4 and a main body 6, with the receiving chamber 4 located on one side of the main body 6. The receiving chamber 4 houses a drive module 5, which is connected to a carrier for loading a material rack 2. An opening is provided on the side of the receiving chamber 4, and the carrier passes through the opening under the drive of the drive module 5. A door 41 is installed on the receiving chamber 4 to cover the opening.

[0028] In this design, the hatch 41 is pivotally connected to the receiving chamber 4, allowing the hatch 41 to rotate relative to the receiving chamber 4. This means the relative position of the hatch 41 and the opening can be changed, enabling the hatch 41 to open and close. The analyzer hatch 41 opens when the material rack 2 is moving in or out, and closes at other times. This design avoids interference from external light sources with internal detection results and reduces the gas exchange area between the inside and outside of the analyzer, thus reducing the probability of dust entering the analyzer.

[0029] Specifically, the accommodating compartment 4 includes a base plate 11, a carrier slidably connected to the base plate 11, and a door 41 pivotally connected to the base plate 11. A resilient reset unit 43 is connected between the door 41 and the base plate 11. In one embodiment, the reset unit 43 controls the opening and closing of the door 41, including: when the reset unit 43 is in a large deformation state, the door 41 moves away from the opening; when the reset unit 43 is in a small deformation state or a recovery state, the door 41 covers the opening. In this embodiment, the push force of the carrier on the door 41 causes the reset unit 43 to elastically deform, and after the reset unit 43 elastically recovers, it drives the door 41 to reset. Preferably, when the reset unit 43 is in a small deformation state, the door 41 covers the opening, so that the door 41 applies a certain pressure to the surface of the accommodating compartment 4, ensuring the sealing between the door 41 and the opening. For example, the reset unit 43 is a torsion spring. The hatch 41 can be automatically reset by a torsion spring, which can effectively simplify the operation steps and prevent the operator from forgetting to close the hatch 41 due to negligence, thus affecting normal testing.

[0030] Furthermore, driven by the drive module 5, the vehicle contacts the hatch 41 and rotates the hatch 41 from covering the opening to moving away from the opening. The vehicle pushes the hatch 41 to rotate, thereby pushing at least part of the vehicle out of the receiving compartment 4 through the opening. When the vehicle has completely returned to the receiving compartment 4, the vehicle separates from the hatch 41, and under the restoring action of the reset unit 43, the hatch 41 covers the opening.

[0031] Furthermore, a contact screen is installed on one surface of the main body 6, and the hatch 41 and the contact screen are located on the same side of the main body 6 and the housing compartment 4. Because the hatch 41 and the contact screen are on the same side, the operator can operate the analyzer from the same side, which facilitates operation.

[0032] In some embodiments of this application, see Figure 4 , 5 As shown, the carrier is equipped with a connecting unit, and the material rack 2 is equipped with a mating unit. The carrier and the material rack 2 are slidably connected. As the material rack 2 slides relative to the carrier, the connecting unit gradually approaches the mating unit until the connecting unit and the mating unit engage, thereby restricting the relative movement between the carrier and the material rack 2. The carrier can improve the efficiency and stability of sample injection.

[0033] The carrier comprises a base plate 11 and two side plates 12, which are tightly connected to the base plate 11 and symmetrically arranged on both sides of the base plate 11. A limiting groove is formed between the two side plates 12, through which the feeding rack 2 passes, i.e., the feeding rack 2 slides within the limiting groove. The side plate 12 has a stepped cross-section and protruding ribs. The feeding rack 2 has sliding grooves 23 that match the ribs. The sliding connection between the carrier and the feeding rack 2 is achieved by the ribs engaging with the sliding grooves 23. Specifically, the stepped side plate 12 has a concave guide groove, and the feeding rack 2 has sliding protrusions 24 that engage with the guide groove. In this design, the ribs are installed in the sliding grooves 23, and the sliding protrusions 24 are installed in the guide grooves, allowing the carrier and the feeding rack 2 to engage with each other to achieve a sliding connection.

[0034] One end of the side plate 12 is connected to the base plate 11, and the other end of the side plate 12 is provided with a guide slope. The spacing between the two symmetrical guide slopes gradually decreases along the direction towards the base plate 11 until the width of the limiting groove between the two side plates 12 is consistent with the width of the material rack 2. The guide slope can guide the material rack 2 so that the protrusions and sliding protrusions 24 are accurately installed into the slide groove 23 and the guide groove, avoiding the phenomenon of jamming during the sliding of the material rack 2.

[0035] In this scheme, when the material rack 2 is fully inserted into the carrier, the mating unit on the material rack 2 and the connecting unit on the base plate 11 cooperate with each other to slide the material rack 2 to a predetermined position. The cooperation between the connecting unit and the mating unit prevents the material rack 2 from shaking or accidentally falling off during use.

[0036] In a preferred embodiment, the connecting unit and the mating unit can be mated by magnets attracting iron blocks or magnets attracting each other. The mutual attraction between magnets attracting iron blocks or magnets attracting each other (where the surfaces of the two magnets have opposite magnetic properties) ensures a stable connection between the rack 2 and the carrier. At the same time, when it is necessary to remove the rack 2, only a certain pulling force needs to be applied to overcome the magnetic force, which facilitates operation.

[0037] It is understood that the connection unit and the mating unit can be mated, including but not limited to the mating of a magnet and an iron block, a magnet and a magnet, or a snap-fit ​​and a bayonet. The connection unit and the mating unit can also be mated in a common detachable connection structure, such as a snap-fit ​​and a bayonet engagement. The detachable connection structure of the snap-fit ​​and bayonet not only provides a more secure fixation, preventing the material rack 2 from accidentally falling off during use, but also allows for easy disengagement through simple operation, thus enabling the material rack 2 to be removed from the carrier.

[0038] Furthermore, the material rack 2 has two opposing end faces, with the mating unit 21 located on one end face and a handle unit 22 on the other end face. The handle unit 22 facilitates the operator's gripping of the material rack 2, making it convenient for insertion and removal. Specifically, the other end face of the material rack 2 has a clearance groove 221, forming a hook-shaped handle unit 22 on the other end of the material rack 2. The hook-shaped handle unit 22 increases the gripping space for the fingers, improving the comfort and stability of operation and preventing slippage when pulling the material rack 2.

[0039] In use, the operator can grip the material rack 2 using the handle unit 22 and insert it into the carrier along the groove on the side plate 12. The guide ramp on the side plate 12 guides the material rack 2 smoothly into the correct position. Once the material rack 2 is fully inserted, the mating unit and the connecting unit cooperate to fix the material rack 2 in the predetermined position. At this time, the sample tube 3 is securely placed in the sample compartment 25 of the material rack 2, facilitating subsequent sample processing by the analyzer. When it is necessary to change the sample or remove the material rack 2, the operator only needs to apply a certain pulling force through the handle unit 22 to overcome the connecting force between the connecting unit and the mating unit and remove the material rack 2 from the carrier.

[0040] In some embodiments of this application, the rack 2 is provided with multiple sample compartments 25 for loading sample tubes 3. The rack 2 slides on the carrier along a straight line, and the multiple sample compartments 25 are arranged along this straight line on the rack 2. Furthermore, the drive module 5 drives the carrier to move along this straight line. An identification module is installed on the frame of the receiving compartment 4. As the rack 2 moves along this straight line, the sample tubes 3 loaded on the rack 2 are identified one by one by the identification module to obtain information from the sample tubes 3.

[0041] In this solution, the identification module is used to detect the sample tubes 3 temporarily stored on the rack 2. The identification module can be a barcode scanner, RFID reader, or camera, capable of reading the identification information on the sample tubes 3, such as barcodes, QR codes, or RFID tags. The rack 2 and the carrier can move relative to the identification module. When the drive module 5 drives the carrier to move, the sample tubes 3 on the rack 2 will pass through the detection area of ​​the identification module 4 in sequence, allowing the identification module to read the information of each sample tube 3 one by one.

[0042] Furthermore, the guide rail 15 is mounted on the base 42, and the slider 14 is mounted on the carrier. The slider 14 is slidably connected to the guide rail 15, which extends along this straight line. Driven by the drive module 5 and guided by the slider 14 and the guide rail 15, the carrier slides along this straight line.

[0043] In actual use, the operator first places the sample tube 3 into the sample compartment 25 of the material rack 2, and then inserts the material rack 2 into the carrier along the groove on the side plate 12. Once the material rack 2 is fully inserted, the mating unit on the material rack 2 cooperates with the connecting unit on the base plate 11 to fix the material rack 2 in the predetermined position. Next, the drive module 5 starts working, driving the carrier to move in a straight line, causing the sample tubes 3 on the material rack 2 to pass sequentially through the detection area of ​​the identification module. The identification module reads the identification information on the sample tube 3 and transmits the information to the analyzer's control system. Based on the read information, the control system controls the analyzer to perform subsequent analysis and processing on the corresponding samples.

[0044] This analyzer can automatically process multiple samples, completing sample identification and movement without manual intervention, greatly improving work efficiency and accuracy. Meanwhile, the linearly arranged sample compartments 25 and the linear movement drive simplify the mechanical structure, enhancing the analyzer's reliability and stability.

[0045] Furthermore, a push block 16 is also installed on the vehicle. The push block 16 and the slider 14 are mounted on the same surface of the vehicle, and the push block 16 extends from one end, so that when the vehicle is pushed out of the housing compartment 4, the push block 16 makes priority contact with the hatch 41.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
