[0038] As shown in [Fig.l], [Fig.3] and [Fig.7], the present application provides an incubation device. One embodiment of the incubation device of the present application comprises: a support portion 10 and a cover plate structure 20, wherein the support portion 10 has a first support region 101 and a second support region 102, a first support hole 11 is provided in the first support region 101, and a second support hole 12 is provided in the second support region 102; and the cover plate structure 20 is disposed on the second support region 102 and has an opening position and a covering position, when the cover plate structure 20 is in the covering position, the cover plate structure 20 covers one side upper part of the second support region 102, and when the cover plate structure 20 is in the opening position, the cover plate structure 20 avoids the second support region 102 to expose the second support hole 12.

[0039] By applying the technical solutions of the present embodiment, the support portion 10 is configured to support a reaction cup 1 and provide a suitable incubation temperature for a sample in the reaction cup 1. The support portion 10 is provided with the first support region 101, the first support hole 11 is provided in the first support region 101, and the reaction cup 1 can be placed in the first support hole 11 to perform a routine object that is not likely to volatilize or evaporate; and the support portion 10 is further provided with the second support region 102, the second support hole 12 is provided in the second support region 102, the cover plate structure 20 is arranged on the second support region 102 and has the opening position and the covering position, when the cover plate structure 20 is in the opening position,the cover plate structure 20 avoids the second support region 102 to expose the second support hole 12, at this time, the reaction cup 1 can be placed in the second support hole 102, after the reaction cup 1 is placed, the cover plate structure 20 switches between the opening position and the covering position, the cover plate structure 20 covers the upper side of the second support region 102, so that the amount of evaporation or volatilization of the sample in the reaction cup 1 can be reduced, a change in concentration of the sample is reduced, that is, the reaction cup 1 can be placed in the second support hole 12 to carry out a special object which is likely to volatilize or evaporate. In the present embodiment, the incubations of the routine object and the special object are integrated into an incubation device,the actions of placing the reaction cup 1 into the first support hole 11 or the second support hole 12 and switching the cover plate structure 20 between the opening position and the covering position can all be implemented by a machine without the need for manual operation of a worker, thereby reducing the labor intensity of the worker and also avoiding misoperations caused by the introduction of manual operation. Therefore, the technical solutions of the present embodiment can effectively solve the problem in the related art that objects which are liable to volatilize or evaporate in an incubation process are incubated separately outside a reaction system, resulting in a tedious operation.

[0040] In the description of the present embodiment, the expression "routine object" means an element which is not likely to volatilize or evaporate during of the incubation process, and the term "special item" means an item that is likely to volatilize or evaporate during the incubation process.

[0041] For example, when performing a coagulation test, the routine object needs to be incubated for 1-5 minutes in a 37°C environment; when performing objects such as an aPTT correction test, a long-term incubation is required, the worker usually performs 2 hours of incubation in a water bath container outside the incubation device, during this process, the sample is likely to evaporate, and therefore it is a special object.APTT is the abbreviation of activated partial thromboplastin time, a coagulation function test indicator capable of reflecting the overall activity of coagulation factors in an intrinsic coagulation pathway, especially in the first stage, and is widely used for screening and measuring defects of intrinsic pathway coagulation factors, such as factors XI, VIII and IX, and can also be used for primary screening diagnosis of hemorrhagic diseases and laboratory monitoring of heparin anticoagulant therapy; and the correction test is also called a mixing test or mixing study, in which related test objects are tested again after a patient's plasma is mixed with plasma of normal people in proportion.Performing the TCA correction test in the incubation device of the present embodiment not only reduces the amount of evaporation in the incubation process, but also, since the incubation operations are performed in different support holes, when the item is incubated in the second support hole 12, the routine object can still be incubated in the first support hole 11, which does not affect the experimental process of the routine object.

[0042] Of course, the incubation device of the present embodiment is not only applicable to the TCA correction test which causes evaporation due to long-term incubation, but also to other objects in which the samples or reagents themselves are relatively volatile.

[0043] Furthermore, for tests such as the coagulation test, a doctor or an experimenter often needs to compare and analyze routine object and special object results to obtain a complete analysis result, however, in the prior art, the routine object is performed in an automatic incubation device and the special object is performed separately in the water bath container through the reaction cup with a cover, and due to the different incubation environments and transfer routes between the routine object and the special object, significant test errors are introduced, which poses higher requirements on the experience of the doctor or experimenter. In the present embodiment, the incubations of the routine object and the special object are integrated into a single incubation device, so that other environmental characteristics and reaction cup pathways among others remain relatively consistent, which is beneficial to control variables, thereby helping the doctor or experimenter to produce a reliable analysis result when fully analyzing the routine object and the special object.

[0044] It should be noted that, in the covering position, the structure of the cover plate 20 may be in sealing fit with an upper surface of the second support region 102 or only bear against but not seal the upper surface.

[0045] As shown in Figures 7 and 8, a gripping groove 16 is provided in the second support region 102, and the second support hole 12 is provided in a groove bottom wall of the gripping groove 16.By providing the gripping groove 16 and the second support hole 12 in the bottom wall of the groove of the gripping groove 16, on the one hand, an upper surface of the reaction cup 1 placed in the second support hole 12 can be lower or at the same level as the upper surface of the second support region 102, so that the interior of the second support region 102 is relatively closed when the cover plate structure 20 covers the upper surface of the second support region 102, thereby avoiding or reducing the occurrence of evaporation or volatilization; and on the other hand, a gripping mechanism for clamping the reaction cup 1 can extend into the gripping groove 16 to place or remove the reaction cup 1.

[0046] More specifically, as shown in [Fig.l], [Fig.3], [Fig.4], [Fig.5] and [Fig.7], the support portion 10 comprises a thermostatic element 13, a heating element 14 and a thermal insulation layer 15, the first support hole 11 and the second support hole 12 are both provided on the thermostatic element 13, the heating element 14 is arranged next to the thermostatic element 13 and can heat the thermostatic element 13 to 20°C-50°C, and the thermal insulation layer 15 covers a periphery of the thermostatic element 13 and the heating element 14 as well as a bottom of the thermostatic element 13 and the heating element 14, the thermostatic element 13 is made from a 6063-T5 aluminum alloy, the thermostatic element 13 comprises a first block thermostatic block and a second thermostatic block, which are provided in one piece, a space occupied by the first thermostatic block forms the first support region 101,and a space occupied by the second thermostatic block forms the second support region 102; the heating element 14 is a PI heating film or a silicone rubber heating tape and is bonded under the thermostatic element 13; the thermal insulation layer 15 is thermal insulation cotton and covers the periphery of the thermostatic element, 13 and the heating element 14 as well as the bottom of the heating element 14, so as to expose only an upper surface of the thermostatic element 13 to reduce the heat exchange between the support portion 10 and the outside, so that the thermostatic element 13 maintains a stable temperature.

[0047] It should be noted that the incubation device of the present embodiment is not limited to the coagulation test in which incubation is carried out at 37°C, and is also applicable to other objects in which incubation is carried out at relatively low temperatures (20°C to 50°C).

[0048] In the present embodiment, the first support region 101 and the second support region 102 share a thermostatic element 13 and a heating element 14, so as to reduce costs, facilitate the control of variables and help the physician to issue a reliable analysis conclusion.

[0049] As shown in [Fig.3], [Fig.4], [Fig.6] and [Fig.7], the incubation device further comprises a temperature sensor 181, a temperature control switch 182 and a support member 19, wherein the support member 19 is connected to the periphery of the support portion 10 and can be connected to a frame of a sample analyzer to fix the incubation device on the frame; the temperature sensor 181 is disposed in a central region of the thermostatic element 13 and can detect the temperature of the thermostatic element 13; and the temperature control switch 182 is electrically connected to the temperature sensor 181 and the heating element 14, and when the temperature sensor 181 detects that the temperature of the thermostatic element 13 is higher than a preset value, the heating element 14 is controlled to stop heating.

[0050] As shown in [Fig.4], [Fig.7] and [Fig.8], the structure of the second support hole 12 is the same as that of the first support hole 11. Thus, the first support hole 11 and the second support hole 12 can correspond to the reaction cups 1 with the same model number, therefore on the one hand, the model numbers of the reaction cups 1 corresponding to the incubation device are reduced and on the other hand, the special object and the routine object can be incubated using the reaction cups 1 with the same model number, thereby further reducing the introduction of errors during the overall comparison and analysis, so that the analysis result is more accurate.

[0051] As shown in [Fig.3], [Fig.7] and [Fig.8], a plurality of first support holes 11 are provided in the first support region 101 in an array, and a plurality of second support holes 12 are arranged in the second support region 102. Since the plurality of first support holes 11 and the plurality of second support holes 12 are formed in the array, the trajectory of the gripping mechanism can be conveniently controlled. More specifically, 36 first Support holes 11 are provided in the first support region 101 in a 2x18 fashion, and 6 second support holes 12 are provided in the second support region 102 in a 1x6 manner. Of course, in a specific implementation, the number of first support holes and the array mode of the first support holes, as well as the number of second support holes and the array mode of the second support holes are not limited to the above-mentioned shapes, but can be set by a designer according to needs.

[0052] As shown in [Fig.4], [Fig.8] and [Fig.9], a plurality of second support holes 12 are provided in the second support region 102 in an array, a plurality of partition plates 17 are arranged in the gripping groove 16, the plurality of partition plates 17 divides the gripping groove 16 into a plurality of gripping cavities 161 independent of each other, the plurality of gripping cavities 161 and the plurality of second support holes 12 are arranged in one-to-one correspondence, a cross-sectional area of the gripping cavity 161 is larger than a cross-sectional area of a corresponding second support hole 12, and an upper surface of the partition plate 17 is flush with an upper surface of the second support region 102.By arranging the partition plates 17, when the cover plate structure 20 is in the covering position, the second support region 102 forms a plurality of mutually independent incubation spaces, and the sample in a reaction cup 1 can be incubated in each incubation space, so that the case where the accuracy of the test result is affected by cross-contamination of the samples in the adjacent second support holes 12 during the incubation process can be reduced. Since the cross-sectional area of the gripping cavity 161 is larger than the cross-sectional area of the corresponding second support hole 12, a gripping space is formed between an upper end of the reaction cup 1 and a gripping cavity wall 161, so that the gripping mechanism can conveniently extend into the gripping space to place or remove the reaction cup 1..

[0053] As shown in [Fig.4] and [Fig.9], the second thermostatic block protrudes upwardly relative to the first thermostatic block, a barrier structure is formed between a circumferential side wall of the second thermostatic block and a circumferential side wall of the gripping groove 16, and when the cover plate structure 20 is in the covering position, a lower surface of the rotating plate 22 abuts against an upper surface of the barrier structure and the upper surfaces of the partition plates 17, so that the second support region 102 forms a plurality of incubation spaces independent of each other.

[0054] As shown in [Fig.9], when a reaction cup 1 is placed in the first support hole 11 and the cover plate structure 20 is in the covering position, an upper surface of the cover plate structure 20 is at the same level or lower than an upper surface of the reaction cup 1. Thus, when the incubations of the routine object and the special object are performed at the same time on the incubation device, the gripping mechanism can normally operate above the incubation device without complicated movements such as avoidance being required.

[0055] As shown in [Fig. 1] and [Fig. 7], the cover plate structure 20 comprises a rotating shaft 21 penetrating through the support portion 10 and a turntable 22 fixedly connected to the rotating shaft 21, and the rotating shaft 21 is capable of driving the turntable 22 to rotate, so that the cover plate structure 20 is switched between the covering position and the opening position. The structure for covering the upper side of the second support region 102 is designed as the turntable 22, and the turntable 22 is driven by the rotating shaft 21 to swing, thereby having the advantages of being simple in structure and reliable in control.

[0056] As shown in [Fig.l] to [Fig.3], the incubation device further comprises a position sensing structure 30, configured to sense a position of the cover plate structure 20. The position sensing structure 30 can sense the position of the cover plate structure 20 to determine whether the cover plate structure 20 is in the cover position or the open position.

[0057] Specifically, as shown in [Fig.l] and [Fig.2], the position sensing structure 30 comprises a sensing groove 31 and a sensing member 32 disposed on the rotating shaft 21, and when the rotating shaft 21 rotates, the rotating shaft 21 drives the sensing member 32 to switch between a state where it extends into the sensing groove 31 and a state where it is outside the sensing groove 31. In the present embodiment, the position sensing structure 30 further comprises two sensing arms 33 spaced apart from each other and connecting arms 34 connected to the end portions of the two sensing arms 33, the two sensing arms 33 and the connecting arms 34 together form the sensing groove 31, one of the two sensing arms 33 can transmit an optical coupling signal and the other can receive the optical coupling signal.When the cover plate structure 20 is in the covering position, the pickup element 32 extends into the pickup groove 31 to block a transmission path of the optical coupling signal; and when the cover plate structure 20 is in the opening position, the pickup element 32 is located outside the pickup groove 31, so that the signal . optical coupling signal can be transmitted smoothly. By determining whether the pickup arm 33 for receiving the optical coupling signal receives the optical coupling signal, it is possible to determine the position of the cover plate structure 20.

[0058] As shown in [Fig.3], [Fig.6] and [Fig.7], the incubation device comprises a drive portion 40, the drive portion 40 comprises a drive motor 41 disposed under the support portion 10 and a transmission structure 42 disposed between the drive motor 41 and the rotating shaft 21, and the transmission structure 42 comprises a first transmission wheel 421 sleeved on an output shaft of the drive motor 41, a second transmission wheel 422 sleeved on the rotating shaft 21, and a transmission belt 423 sleeved outside the first transmission wheel 421 and the second transmission wheel 422.More specifically, the drive motor 41 is a stepping motor, and the drive motor 41 drives the rotating shaft 21 and the turntable 22 to rotate at a certain angle via the first transmission wheel 421, the second transmission wheel 422 and the transmission belt 423, so as to change the position of the cover plate structure 20, thereby having the advantage of being simple in structure and easy to control. As shown in [Fig. 5], the drive portion 40 is further provided with a motor frame 43, and the drive motor 41 is installed under the support portion 10 via the motor frame 43.

[0059] Of course, in embodiments not shown, the cover plate structure may also be designed as a structure for switching between the covering position and the opening position by translation, for example, the translation of a cover plate is implemented by a rack structure or a worm nut structure to close the second support region or avoid the second support region.

[0064] In describing the present invention, it is to be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "transverse, longitudinal, vertical, horizontal" and "top, bottom" and the like are generally orientation or positional relationships illustrated on the basis of the drawings, in the absence of indications to the contrary, these orientation terms do not indicate or imply that the apparatuses or objects mentioned must have specific orientations or must be constructed and operate in specific orientations, and therefore cannot be construed as limiting the scope of protection of the present invention; and the Orientation words "inside and outside" refer to the inside and outside of the contours of the components themselves.

[0065] For ease of description, spatial terms, such as "on," "above," "on the top surface," "over," and the like, may be used herein to describe the spatial positional relationships between a device or feature and other devices or features illustrated in the figures. It is understood that the spatial terms are intended to encompass different orientations of a device in use or operation, in addition to the orientations described in the figures. For example, if the device of the figures is turned upside down, the device that is described as being "on top of other devices or structures" or "above other devices or structures" would then be positioned as being "below other devices or structures" or "below other devices or structures."Thus, the exemplary term "above" may include both "above" and "below" orientations. The apparatus may also be positioned differently (rotated 90 degrees or in other orientations), and the space-related descriptions used herein are interpreted accordingly.

[0066] Furthermore, it should be noted that the terms "first", "second" and other similar terms are used to define components and parts, and only serve to distinguish corresponding components and parts, and unless otherwise indicated, the above words have no particular meaning, and therefore cannot be interpreted as limiting the scope of protection of the present invention.

[0067] The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and amendments. All equivalent and similar modifications, improvements, and replacements made within the spirit and principles of the present invention are to be included within the scope of protection of the present invention.
