Description

Technical Field

[0001] The utility model relates to the technical field of analyzers, in particular to a closed emergency sample injection device and an analyzer system. Background Art

[0002] The emergency injection function is a necessary function of current blood cell analyzers to meet the needs of emergency sample testing. The injection methods of emergency samples can generally be divided into open emergency injection and closed emergency injection. Open emergency injection means that the user manually opens the test tube cap and then places the test tube against the sampling needle extending from the analyzer to aspirate the sample. It is compatible with any test tube specifications. Closed emergency injection means that the test tube is directly placed in the test tube holder extending from the instrument, and then the test tube holder is retracted into the instrument to the sample aspiration position before aspiration. Therefore, under the closed emergency injection method, for puncturable test tubes, aerosol contamination is prevented, the risk of sample splashing is reduced, and the user's opening operation is reduced. Therefore, based on safety and ease of operation, the analyzers currently on the market are mainly closed emergency models. However, for closed emergency models, the test tube holder structure of the analyzer must be compatible with the various test tube specifications used by the user in order to meet the requirements of use. This also puts high requirements on the test tube compatibility and interactivity of various analyzers.

[0003] However, there are many deficiencies in various current analyzers. For example, the test tube type compatibility of the test tube holder is poor, or the compatibility is good but the test tube limiting structure of the test tube holder is complex. The motion component used to drive the test tube holder out of the bin occupies a large space, has a complex structure and is costly. Users need to select the test tube placement position when selecting the measurement mode based on the test tube, which increases the risk of human error in judgment; when the blood analyzer is used online with the fluorescent immunoassay instrument, or when forming an assembly line, taller serum test tubes (about 100mm) cannot pass through the inner feed channel of the blood analyzer, which restricts users to place the test tubes according to the rules (one row of test tube racks has one height specification sample tube), which causes inconvenience.

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0064] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0065] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0066] Combine Figure 1 and Figure 2 The embodiment of the present utility model provides a closed emergency sampling device, which is installed on a fixed bracket 1 in the sampling area of ​​the analyzer. The closed emergency sampling device includes: a linear drive component 2, an automatic position blocking component 3 and a placement seat component 4;

[0067] The linear drive assembly 2 is mounted on the fixed bracket 1 and can be driven linearly in the Y direction;

[0068] The placement seat assembly 4 can rotate relative to the fixed bracket 1 in the YZ direction, and a test tube placement position is provided on the top of the placement seat assembly 4;

[0069] The automatic blocking component 3 is slidably assembled on the fixed bracket 1 in the Y direction and is connected to the linear drive component 2; the automatic blocking component 3 is opposite to the placement seat component 4 on the Y direction and corresponds to the feed channel 8 in the sampling area (refer to Figure 6 )middle;

[0070] Among them, the linear drive component 2 is used to drive the automatic position blocking component 3 to slide to avoid the feed channel 8, while driving the automatic position blocking component 3 to link the placement seat component 4 to rotate in the YZ direction, thereby rotating the test tube placement position out of the warehouse.

[0071] In this embodiment, the automatic blocking component 3 is combined with the placement seat component 4, and the automatic blocking component 3 is provided with a avoidance function for the feed channel 8, which cleverly solves the problem of high test tubes being blocked when passing through the feed channel 8 when two analyzers are used online.

[0072] In this embodiment, the linear drive component 2 drives the automatic position blocking component 3 to move linearly in the Y direction, and the placement seat component 4 is linked to rotate in the Y and Z directions. The movement of the placement seat component 4 only requires the rotation space of the end to be realized, and the space occupied is very small. In addition, the rotation dumping method is adopted, so that the space after the test tube placement position is out of the warehouse is larger, which can better meet the operator's operating space for taking and placing test tubes (reference Figure 5 (see the schematic diagram of the warehouse exit status).

[0073] The avoidance function of the automatic position blocking component 3 added in this embodiment can also be used as an adjustment avoidance position in the production assembly process (when the automatic sampler and the main machine are just assembled, the relative position accuracy of the sampling needle and the automatic sample suction position 9 of the automatic sampler is not yet determined. The traditional method is to pre-lock the automatic position blocking component 3 (to prevent loss) when assembling the automatic sampler, remove it before debugging, and assemble the automatic position blocking component 3 after the position needs to be accurately adjusted to avoid damage to the sampling needle after position offset. However, such repeated disassembly and assembly operations are cumbersome and do not meet the requirements of modular assembly). The solution of this embodiment can first directly assemble the automatic position blocking component 3, and when adjusting, move the automatic position blocking component 3 to the avoidance position, and then drive it back to its original position after the adjustment is completed. The operation is simple.

[0074] Specific, combined Figure 3 Figure 4 In order to facilitate understanding of the technical effect of the present embodiment in which the automatic blocking component 3 and the placement seat component 4 are linked together, the sampling scheme of the conventional hematology analyzer is introduced: Conventional hematology analyzers usually use 2mL venous blood test tubes (height ≤ 85mm) for sample testing, so the automatic blocking component 3 of the sampling area is set at a height slightly higher than the 85mm test tube passing height (reference Figure 3), and at the same time, the bottom of the swab of the sampling needle of the analyzer is also slightly higher than the automatic blocking component 3, ensuring that the sampling needle can pass smoothly above the automatic blocking component 3, so as to minimize the downward sampling stroke of the sampling needle, reduce wear and tear, and increase the service life of the sampling needle. With the market demand for automation of testing laboratories, the online and assembly line forms of different types of analyzers are becoming more and more common. The height specifications of the test tubes used in different analyzers are different. For example, the serum test tubes used in fluorescent immunoassays are generally about 100mm high (reference Figure 4 ), if it forms an assembly line with a blood analyzer, the current automatic position blocking component 3 will block high test tubes from passing through the blood cell instrument, which requires the user to sort out the test tubes of different heights in advance and put them in different test tube racks according to specifications, but this will cause inconvenience to the user and is not smart enough (if the test tubes are mixed, the test tube rack cannot pass through the blood analyzer, which requires the operator to manually take out the test tube rack). One solution is to raise the existing automatic position blocking component 3 of the blood analyzer, and the sampling needle of the analyzer host should be raised accordingly, but this causes a large change in the layout of the analyzer unit, and the sampling needle will inevitably be lengthened, which increases the risk of wear and bending of the sampling needle and reduces the service life of the sampling needle. Therefore, in summary, the present embodiment designs the automatic position blocking component 3 to be slidable, so as to add a avoidance function for the feed channel 8, and at the same time uses the sliding function of the automatic position blocking component 3 as the driving force for the linkage placement seat component 4 to rotate out of the warehouse, thereby realizing the combination of the two, thereby achieving the above-mentioned beneficial effects of the present application.

[0075] Combine Figure 2 As shown, in one embodiment, the closed emergency sampling device also includes: a closed position blocking component 5, which is fixedly installed on the fixed bracket 1, and the closed position blocking component 5 is provided with a closed position sampling hole 521 for the sampling needle to pass through along the Z direction, and the closed position sampling hole 521 is located above the test tube placement position in the Z direction.

[0076] In this embodiment, the closed position blocking assembly 5 includes a vertical plate 51 and a closed position blocking piece 52. The closed position blocking piece 52 is arranged on the top of the vertical plate 51 and extends horizontally in the direction of the chamber out. A closed position sampling hole 521 is opened at the horizontal extension position. The closed position sampling hole 521 can be in the shape of a strip hole feature. The Y-axis position of the closed position sampling hole 521 is the closed sampling position 10 for sampling the emergency test tube in the closed emergency sampling device. The closed position sampling hole 521 is located above the test tube placement position in the Z direction. Based on this, when the sampling needle is sampling at the closed sampling position 10, it can pass through the closed position sampling hole 521 downward along the Z direction to enter the test tube placement position below for sampling. In addition, the closed position blocking piece 52 is used to prevent the sampling needle from contacting the top of the test tube with the sampling needle cleaning swab during the process of the closed sampling position 10 rising to aspirate the sample.

[0077] In one embodiment, the closed emergency sample injection device further comprises: a rotary drive assembly 6 , which is mounted on the fixed bracket 1 and can rotate in the YZ direction;

[0078] The bottom of the placement seat assembly 4 is axially connected to the rotation drive assembly 6, and the top of the placement seat assembly 4 is provided with two test tube placement positions in the X direction. The rotation drive assembly 6 is used to drive the placement seat assembly 4 to rotate in the YZ plane to switch one of the two test tube placement positions to correspond to the closed position sample suction hole 521 in the Z direction.

[0079] In this embodiment, the rotation drive assembly 6 may include a drive motor 62 and a drive bracket 61. The two sides of the drive bracket 61 are pivotally connected to the fixed bracket 1 through a rotating shaft 63. The drive motor 62 is fixedly installed on the drive bracket 61. The bottom of the placement seat assembly 4 is connected to the motor shaft of the drive motor 62, and the rotation center of the two test tube placement positions is coaxial with the motor shaft; the drive motor 62 can drive the placement seat assembly 4 to rotate a fixed angle around the rotation center of the two test tube placement positions, thereby realizing the switching of the two test tube placement positions.

[0080] In this embodiment, on the basis of setting two test tube placement positions, when the placement seat assembly 4 rotates out of the warehouse, both test tube placement positions will be out of the warehouse, but generally the test tube will only be loaded into one of the test tube placement positions. In order to avoid errors in the test tube placement position, a vertical rod is set on the driving bracket 61, and a placement blocking piece is extended laterally from the top of the vertical rod in the direction of out of the warehouse; when the placement seat assembly 4 is not out of the warehouse, the placement blocking piece and the closed position blocking piece 52 are respectively located above the two test tube placement positions. By rotating the driving assembly 6 to drive the placement seat assembly 4 to rotate, the two test tube placement positions can be switched below the placement blocking piece and the closed position blocking piece 52. Based on this, when it is necessary to load the test tube to the test tube placement position, the system responds to the designated test tube placement position selected by the user, controls the rotary drive assembly 6 to rotate, so that the designated test tube placement position corresponds to below the closed position blocking piece 52, and at this time the other test tube placement position is below the placement blocking piece, and then controls the automatic position blocking assembly 3 to slide and links the rotary drive assembly 6 to rotate in the YZ direction, so that the placement seat assembly 4 drives the placement blocking piece and the two test tube placement positions to rotate out of the warehouse together. After rotating out of the warehouse, the designated test tube placement position is away from the obstruction of the closed position blocking piece 52, and the test tube can be loaded, while the placement blocking piece remains unchanged relative to the other test tube placement position. The test tube cannot be placed in the other test tube placement position due to the obstruction of the placement blocking piece. The operator can only place the test tube in the designated test tube placement position, so that there will be no problem of misplacement.

[0081] In one embodiment, the closed emergency sample injection device further includes: an elastic reset member 7, the rotation drive assembly 6 is connected to the fixed bracket 1 via the elastic reset member 7, and the elastic reset member 7 is used to drive the rotation drive assembly 6 to rotate and reset.

[0082] In this embodiment, during the process of the rotating drive component 6 and the placement seat component 4 rotating out of the warehouse, the elastic reset component 7 will be stretched, so that the elastic reset component 7 generates an elastic force that drives the rotating drive component 6 and the placement seat component 4 to rotate back into the warehouse, thereby achieving stable traction back to the warehouse.

[0083] In this embodiment, the elastic return member 7 can be composed of a tension spring, a compression spring 43 or a magnet, so as to stably pull the rotation drive assembly 6 and the placement seat assembly 4 back into the warehouse.

[0084] The automatic position blocking component 3 of the present application is described in detail below.

[0085] In one embodiment, the automatic position blocking component 3 is provided with an automatic position sampling hole 321 for the sampling needle to pass through along the Z direction; when the automatic position blocking component 3 is in the feed channel 8, the automatic position sampling hole 321 corresponds to the automatic sampling position 9 in the feed channel 8 in the Z direction.

[0086] In this embodiment, the automatic position blocking assembly 3 may include a mounting plate 31 and an automatic position blocking piece 32. The mounting plate 31 is vertically arranged relative to the fixed bracket 1. The automatic position blocking piece 32 is arranged on the top of the mounting plate 31 and extends laterally toward the feed channel 8. An automatic position sampling hole 321 is provided at the laterally extended position. The shape of the automatic position sampling hole 321 may be a bar-shaped hole feature. Based on this, when the sampling needle is in the automatic position for sampling, it passes through the automatic position sampling hole 321 downward along the Z direction to enter the automatic sampling position 9 in the feed channel 8 (the automatic sampling position 9 here is a position in the feed channel 8 for sampling non-emergency test tubes) for sampling. In addition, the automatic position blocking piece 32 is used to prevent the sampling needle from contacting the top of the test tube with the sampling needle cleaning swab during the raising process of the automatic sampling position 9.

[0087] In this embodiment, in the online and assembly line forms of different types of analyzers, the automatic position blocking component 3 avoids the feed channel 8 by sliding in a direction away from the feed channel 8, so that the automatic position blocking piece 32 leaves the feed channel 8. Therefore, the bottom of the automatic position blocking component 3 can be slidably assembled on the fixed bracket 1 through a sliding part, and the sliding part is connected to the linear drive component 2. The sliding part can be driven by the linear drive component 2 to move and link the automatic position blocking component 3 to slide in a direction away from the feed channel 8, so that the automatic position blocking piece 32 avoids the feed channel 8.

[0088] Furthermore, the linear drive assembly 2 can drive the sliding member to slide linearly in the Y direction by means of motor synchronous belt transmission, motor screw transmission, cylinder push transmission, etc.

[0089] Furthermore, in some other ways of avoiding the feed channel 8, the automatic position blocking piece 32 can also be rotatably connected to the top of the mounting plate 31, and the automatic position blocking piece 32 can be rotated to rotate backward around the Z direction to avoid the high test tubes in the feed channel 8, or to rotate upward around the X direction to avoid the high test tubes in the feed channel 8.

[0090] In one embodiment, the sliding member may include a guide rail and a push plate 33 sliding on the guide rail, and the push plate 33 has a push rod 34 extending toward one side of the rotation drive component 6. Correspondingly, the drive bracket 61 of the rotation drive component 6 is provided with a baffle 64 corresponding to the push rod 34 in the Y direction.

[0091] In this embodiment, when the slider slides toward the rotary drive assembly 6, the push rod 34 on the push plate 33 abuts against the baffle 64, pushing the rotary drive assembly 6 to rotate out of the bin, thereby pushing the placement seat assembly 4 to rotate out of the bin. Specifically, the vertical plate 51 is located between the rotary drive assembly 6 and the automatic position blocking assembly 3. To achieve the abutment and push of the push rod 34 against the baffle 64, a roller is provided at the end of the push rod 34, which abuts and pushes the baffle 64. The vertical plate 51 also has a through-hole, with the push rod 34 and baffle 64 located on either side of the through-hole in the Y direction.

[0092] Combine Figures 6-8 In one embodiment, the automatic position blocking component 3 can avoid the feed channel 8 by sliding the sliding part, and at the same time, the sliding part can also realize the function of pushing the placement seat component 4 to rotate out of the warehouse. In order to ensure the realization of these two functions, the sliding path of the automatic position blocking component 3 in the Y direction can be optically coupled for identification and positioning.

[0093] In this embodiment, the automatic blocking component 3 is provided with an initial position, an avoidance position and an end position on the sliding path along the Y direction.

[0094] Combine Figure 6 In this embodiment, the automatic position blocking component 3 is used to block the contact between the test tube and the sampling needle cleaning swab in the feed channel 8 during the sampling process.

[0095] Combine Figure 7In this embodiment, when the automatic position blocking component 3 is in the avoidance position, the automatic position blocking component 3 moves toward the rotation drive component 6. At this time, the automatic position blocking piece 32 on the automatic position blocking component 3 has withdrawn from the feed channel 8. At this time, the push rod 34 and the baffle 64 are still in a separated state but the distance between them is reduced (they can be in a state of close contact with each other); the automatic position blocking component 3 in this state is used to avoid the high test tube in the feed channel 8 from passing through.

[0096] Combine Figure 8 In this embodiment, when the automatic position blocking assembly 3 is at the end position, it continues to move toward the rotation drive assembly 6 to a position further away from the feed channel. At this time, the automatic position blocking piece 32 is further deviated from the automatic sample aspirating position 9. At this time, the push rod 34 abuts against the baffle 64. The baffle 64 is pushed by the push rod 34, causing the entire rotation drive assembly 6 to rotate in the YZ direction around the rotating shaft 63 on both sides of the drive bracket 61, thereby driving the placement seat assembly 4 to rotate out of the chamber. Specifically, the rotation angle range of the rotation out of the chamber can be between 20° and 35° (too small test tubes are inconvenient to place, and too large test tubes have the risk of sample splashing).

[0097] In combination with 9 to 12, the placement seat assembly 4 of the present application is described in detail below.

[0098] In one embodiment, the placement seat assembly 4 includes: a main body 41, a closing plate 42, a spring 43, a support column 44 and an adapter 45; the main body 41 is hollowed along the Z direction and forms a second test tube placement position 49; the closing plate 42 is encapsulated at the bottom of the main body 41; the bottom of the spring 43 is connected to the top of the closing plate 42 and is located in the second test tube placement position 49; the bottom of the support column 44 is connected to the top of the spring 43 and is located in the second test tube placement position 49; the bottom of the adapter 45 is inserted into the second test tube placement position 49 and connected to the top of the support column 44; the top of the adapter 45 is used for inserting test tubes of various specifications.

[0099] In this embodiment, the closing plate 42, the spring 43 and the support column 44 are stacked and abutted in sequence in the inner hole of the main body 41 along the Z direction (vertical direction); the main body 41 has an outer cylindrical surface feature and a groove feature. The diameter of the outer cylindrical surface is between 7.5-8.8mm to limit the radial movement of the long micro test tube; the top groove feature is used to avoid the glue protrusion at the bottom of the "bullet head" of some long micro whole blood test tubes, and the inner diameter of the groove is ≥3mm.

[0100] In this embodiment, the second test tube placement position 49 is used to place a long micro blood test tube with an outer diameter of 11-13 mm; in addition, an adapter 45 is added and the adapter 45 is placed in the second test tube placement position 49. For details, see Figure 13a, b, c, and d in the figure respectively show the placement conditions, which are used to place a 1.5 mL EP tube 100a, a 0.5 mL EP tube 100b, a short micro blood test tube without a cap 100c, and a long micro blood test tube 100d in sequence.

[0101] In this embodiment, the spring 43 is in the form of a compression spring 43, and the effective working stroke of the spring 43 is in the range of 3-9 mm to support the sample aspiration requirements of test tubes of different height specifications. The types of needle height positions are reduced through axial elastic adaptation, thereby reducing the user's selection and judgment of test tube types.

[0102] In this embodiment, the second test tube placement position 49 adopts a lower needle height, and the axial elastic function of the spring 43 meets the sample aspiration requirements of test tubes of all specifications.

[0103] In one embodiment, the placement seat assembly 4 also includes: an adapter 46 and a clamping member 47; the adapter 46 is connected to the X-direction side of the main body 41; the bottom of the clamping member 47 is connected to the adapter 46, and the bottom of the clamping member 47 is connected to the adapter 46, and the clamping member 47 includes at least two opposite clamping arms with elastic deformation function; the space between the two clamping arms forms a first test tube placement position 48 for clamping the test tube, and the tops of the two clamping arms are inclined from the inside to the outside to form a guide port.

[0104] In this embodiment, the clamping member 47 is composed of at least two clamping arms, a guide mouth and a limiting cavity (i.e., the placement space of the first test tube placement position 48) and other features; the clamping arms are used to clamp the whole blood test tube, and the minimum limiting size between the clamping arms is in the range of 12-13.5mm (if the limiting size is too small, it is difficult to place the test tube; if it is too large, the test tube limitation is unreliable), and one section of the clamping arm adopts a narrow wall feature; the guide mouth plays a guiding role when placing the test tube, facilitating the insertion of the test tube into the limiting cavity; the inner diameter of the limiting cavity is ≤16mm to meet the placement of test tubes with an outer diameter of 11-15mm (such as venous whole blood test tubes and body fluid test tubes); the material of the clamping member 47 is plastic with sufficient elasticity and toughness, the elasticity ensures that the clamping arm can be easily opened when facing a thicker test tube, and the toughness ensures that the clamping arm will not break after repeated extrusion and deformation.

[0105] In one embodiment, a test tube position determination optical coupler 65 is provided on the drive bracket 61, a first test tube position baffle 461 is provided on the side of the adapter 46 facing away from the main body 41, and a second test tube position baffle 411 is provided on the side of the main body 41 facing away from the adapter 46. The drive component is used to drive the placement seat component 4 to rotate and can position the first test tube position baffle 461 or the second test tube position baffle 411 with the test tube position determination optical coupler 65.

[0106] In this embodiment, when the rotary drive assembly 6 drives the placement seat assembly 4 to rotate, the first test tube position block 461 and the second test tube position block 411 determine the position of the optical coupler 65 based on the test tube position for positioning, ensuring the levelness of the placement seat assembly 4. At the same time, by rotating the optical coupler outward at a fixed angle and then reversing the optical coupler back, the position of the test tube placement position can be determined.

[0107] In this embodiment, the first test tube position baffle 461 and the second test tube position baffle 411 are symmetrically arranged along the rotation center of the placement seat assembly 4, but there are differences in the baffle structure between the two. The test tube position can be determined based on the different baffles and the trigger state of the test tube position determination optical coupler 65. Specifically, when the first test tube position baffle 461 and the test tube position determination optical coupler 65 are positioned, the first reagent tube position is aligned with the closed position sample aspiration hole 521 in the Y direction; when the second test tube position baffle 411 and the test tube position determination optical coupler 65 (reference Figure 2 ) When positioning, the second reagent tube position is aligned with the closed position sampling hole 521Y.

[0108] In this embodiment, the first test tube position baffle 461 and the second test tube position baffle 411 can use the "code tooth" difference feature for feature identification (the optical coupler can be rotated out at a small angle and then returned to its position, and the state change triggered by the optical coupler can be used to determine which baffle it is).

[0109] The utility model simplifies the operation process by adding a rotary drive component 6 and a test tube placement determination optical coupler:

[0110] S1. The user clicks "Emergency" on the software interface and waits for the current automatic sampling position sample test to be completed. The automatic mode is paused and the linear drive component 2 controls the automatic position blocking component 3 to slide to the end position to push the placement seat component 4 to rotate out of the warehouse;

[0111] S2. Set up the analysis order (including number, sample type, measurement mode, etc.);

[0112] S3, manually placing the test tube into the first test tube placement position 48 or the first test tube placement position 48;

[0113] S4. Click "Start". The linear drive component 2 controls the automatic blocking component 3 to slide to the avoidance position or the initial position. The elastic reset component 7 drives the placement seat component 4 to rotate back to the chamber to aspirate the sample. After the aspiration is completed, it rotates out of the chamber.

[0114] S5. Take back the test tube that has been aspirated, and perform emergency aspiration of the next test tube in this way until it is completed. Click "Cancel Emergency" or exit at a scheduled time to complete.

[0115] Based on the process from S1 to S5, the user's manual switching of test tube positions is reduced, and the user's judgment on the matching of test tube positions and test tube types is reduced, thereby reducing the probability of errors and improving the degree of closed injection automation. This reduces the user's manual switching of test tube positions, improves the interactive experience, and reduces the user's judgment on the matching of test tube positions and test tube types, thereby reducing the probability of misplacing test tubes.

[0116] The embodiment of the present invention further provides a sample analysis system, comprising one or more analyzers used online; the above-mentioned closed emergency sample injection device is provided in the sampling area of ​​at least one analyzer.

[0117] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
