It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Referring to fig. 1 and 2, a testing apparatus 10 according to an embodiment of the present invention includes a carrier 110, a reagent pan 120, a sample holder 120, a code scanner 140, a position code 150, a sample tube, and a sample code. The reagent pot 120 may be fixedly disposed, the reagent pot 120 is configured to hold a reagent, the supporting member 110 may perform a circular motion, and may be substantially a disc-shaped structure and disposed around the reagent pot 120, so that the supporting member and the reagent pot 120 may be coaxially disposed, the supporting member 110 is provided with a plurality of supporting positions 111, the plurality of supporting positions 111 are sequentially arranged along an axial direction of the supporting member 110, and the supporting positions 111 may be a hole-shaped structure. The shape of the sample rack 120 may be substantially circular arc, so that the sample rack 120 is adapted to the shape of the bearing position 111, ensuring that the sample rack 120 can be accommodated in the bearing position 111. The sample rack 120 is provided with a plurality of sample sites 121, and the plurality of sample sites 121 may be arranged along an arc to form a row. When the sample racks 120 are received in the respective loading positions 111, the sample positions 121 on the respective sample racks 120 are arranged to form a circle, the sample positions 121 may also be hole-shaped structures, such as circular holes, square holes, elliptical holes, and the like, and the number of the sample positions 121 on one sample rack 120 may be five to ten, or may be less than five or more than ten. The shape of the sample tube is matched with that of the sample position 121, so that the sample tube can be accommodated in the sample position 121 and is used for accommodating a sample to be detected; and the sample code can be arranged on the sample tube in an attaching mode, and the sample code records the relevant information of the patient. In other embodiments, the carrier 110 may also move linearly, for example, the carrying positions 111 are arranged linearly on the carrier 110, the sample positions 121 are arranged linearly on the sample racks 120, and when the sample racks 120 are received in the carrying positions 111, the sample positions 121 on the sample racks 120 are arranged to form a straight line.

In some embodiments, the number of the scanners 140 is one, and the scanners 140 may be fixedly disposed relative to the reagent pans 120. The number of the position codes 150 is also one, and the code scanner 140 is fixedly arranged, for example, the code scanner 140 may be directly fixed on the reagent pot 120, or for example, the code scanner 140 may be fixed at a position located between the carrier 110 and the reagent pot 120. The position code 150 may be a bar code, a two-dimensional code, a three-dimensional code, or the like. During the movement of the carrier 110, when the sample code moves to the identification range of the code scanner 140 following the carrier 110, the code scanner 140 can scan the sample code, so as to identify and read the information in the sample code. When the position code 150 is within the identification range of the scanner 140, the scanner 140 can also identify the position code 150.

In some embodiments, the position codes 150 may be located just in front of the scanners 140, which may be understood as the scanners 140 and the position codes 150 are both spaced apart along the radial direction of the carrier 110, the scanners 140 are located outside the carrier 110, and the carrier 110 is disposed around the position codes 150. When one of the carrying bits 111 is made to correspond to the scanner 140 during the movement of the carrying member 110, the carrying bit 111 will be located just in front of the scanner 140 and between the scanner 140 and the position code 150, and then the carrying bit 111 is made to be within the identification range of the scanner 140. Therefore, when the sample rack 120 is not accommodated in the carrying position 111 of the carrying position 111 located right in front of the barcode scanner 140, the carrying position 111 can be marked as an empty position, so that no sample rack 120 in the carrying position 111 shields the position code 150, thereby ensuring that the barcode scanner 140 can recognize the position code 150 through the space of the empty position. When the sample rack 120 is received in the receiving position 111, the receiving position 111 can be marked as a full position, so that the sample rack 120 in the receiving position 111 can block the position, and the scanner 140 cannot pass through the sample rack 120 to recognize the position code 150. In other embodiments, for example, when the carrying bit 111 in front of the barcode scanner 140 is an empty position, the light emitted by the barcode scanner 140 is strong, so that the barcode scanner 140 can recognize the position code 150; when the carrying position 111 in front of the barcode scanner 140 is a full position, the light emitted from the barcode scanner 140 is absorbed or reflected by the sample holder 120, so that the barcode scanner 140 cannot recognize the position code 150. For another example, when the carrying bit 111 in front of the barcode scanner 140 is empty, the barcode scanner 140 is in an on state, so that the barcode scanner 140 can recognize the position code 150; when the carrying bit 111 in front of the scanner 140 is in the full position, the scanner 140 is in the off state under the trigger of the sample rack 120 in the full position, so that the scanner 140 cannot recognize the position code 150.

The working principle of the test apparatus 10 is described below:

when the carrier 110 moves and the carrying position 111 in front of the scanner 140 is a full position, the scanner 140 cannot recognize the front position code 150 under the shielding effect of the sample rack 120, and thus it is determined that the sample rack 120 is accommodated in the carrying position 111. And make the carrier 110 rotate intermittently, the angle that the carrier 110 rotates at each time is the angle spaced between two adjacent sample positions 121, therefore, for the convenience of description, two adjacent sample positions 121 are respectively marked as a first sample position and a second sample position, in the case that the first sample position is located right in front of the code scanner 140, the code scanner 140 can identify and read the sample code on the sample tube located in the first sample position, after the reading is completed, the carrier 110 rotates once, the first sample position will leave the right in front of the code scanner 140, and make the second sample position be located right in front of the code scanner 140, so that the code scanner 140 can identify and read the sample code on the sample tube located in the second sample position. And so on, until each sample site 121 on the sample rack 120 in the full position is located directly in front of the scanner 140. In the process of sequentially recognizing and reading the sample code at the full position by the scanner 140, the speed of the carrier 110 at each rotation is recorded as the normal speed. For example, if there are five sample sites 121 on the sample rack 120, the carrier 110 will intermittently rotate five times, so that five samples pass right in front of the scanner 140 in sequence. After the carrier 110 has completed five rotations, the next carrier position 111 adjacent to the full position is moved to the front of the code scanner 140; obviously, when the sample positions 121 on the sample rack 120 in the full position are all away from the front of the scanner 140, the carrier 110 will have five stops, i.e., five times the carrier 110 is at rest. In other words, the carrier 110 will have five stops during the arc of the carrier 110 over the full position.

During the movement of the carrier 110, when the carrying position 111 in front of the scanner 140 is an empty position, the shielding of the sample rack 120 can be eliminated, and the scanner 140 recognizes the front position code 150, so as to determine that the sample rack 120 is not accommodated in the carrying position 111. The carrier 110 will rotate continuously so that the next carrier position 111 adjacent to the empty position is within the identification range of the code scanner 140 within the set time. Specifically, the carrier 110 will always be in motion during the empty position leaving the front of the scanner 140, in other words, the carrier 110 will not stop during the arc occupied by the empty position of the carrier 110. Since the load bearing members 110 will have five stops during the rotation of the load bearing members 110 through the arc occupied by the full position, the load bearing members 110 will not have any stops during the rotation of the load bearing members 110 through the arc occupied by the empty position. It can be understood that the time required for the empty bit to enter the range identified by the scanner 140 is denoted as a first time, and the time required for the full bit to enter the range identified by the scanner 140 is denoted as a second time, and the first time will be less than the second time. Further, the speed of the continuous motion generated by the carrier 110 driving the empty position away from the code scanner 140 is a fast speed, which is greater than the normal speed, thereby further reducing the first time. In other embodiments, the continuous motion of the carrier 110 with the empty position away from the code scanner 140 may also have a speed equal to the normal speed.

Therefore, by the cooperation of the code scanner 140 and the position code 150, the status of the bearer bit 111 located in front of the code scanner 140 can be effectively determined, so that the bearer bit 111 can be determined to be an empty bit or the bearer bit 111 can be determined to be a full bit. When the carrying position 111 is an empty position, that is, the carrying position 111 is in an empty state not accommodating the sample rack 120, the carrying member 110 can move continuously, so that the empty position is driven to rapidly leave the code scanner 140 within a relatively short first time, so that the next carrying position 111 adjacent to the empty position is within the identification range of the code scanner 140. When the carrying position 111 is a full position, that is, the carrying position 111 is in a full position state for accommodating the sample rack 120, so that the carrying member 110 can perform clearance motion, and the carrying member 110 moves by an angle between two adjacent sample positions 121 each time, thereby ensuring that each sample position 121 can stay at a certain time right in front of the code scanner 140, and ensuring that the code scanner 140 can identify and read the sample code.

If the empty position and the full position are not determined by the joint action of the code scanner 140 and the position code 150, in operation, the carrier 110 is always in the clearance motion state, that is, the carrier 110 moves by the angle between two adjacent sample positions 121 every time, so that each sample position 121 can be ensured to stay in front of the code scanner 140 for a certain time, so as to ensure that the code scanner 140 can identify and read the sample code. There will still be a pause in the carrier 110 during the arc of rotation of the carrier 110 through the empty position, for example, five pauses will be present in the carrier 110 when the number of sample positions 121 on the sample rack 120 is five. In fact, the identification of the code scanner 140 is equivalent to doing useless work, given that no sample holder 120 is present in the empty position, i.e. no sample code is present. Therefore, it will take a lot of time for the carrier 110 to bring the empty position away from the barcode scanner 140, so that the identification and reading of the sample code on the full position requires a long waiting time, thereby reducing the identification and reading efficiency of the sample code, and finally reducing the testing efficiency of the whole testing device 10.

With the test apparatus 10 in the above embodiment, by the cooperation of the code scanner 140 and the position code 150, it can be determined whether the carry bit 111 located in front of the code scanner 140 is an empty bit or a full bit. When the empty position is determined, the bearing part 110 continuously moves, so that the pause time generated in the process that the bearing part 110 drives the empty position to leave the code scanner 140 is eliminated, the first time is shorter than the second time, namely, the empty position quickly leaves the code scanner 140 in the relatively short first time, the recognition and reading of the sample code on the full position are ensured to only need short waiting time, the recognition and reading efficiency of the sample code is improved, and the testing efficiency of the whole testing device 10 is finally improved. Further, when the speed of the continuous motion generated by the carrier 110 driving the empty position to leave the barcode scanner 140 is a fast speed, the time required for the empty position to completely leave the barcode scanner 140 can be further reduced, thereby further improving the testing efficiency.

In some embodiments, the number of the scanners 140 is one, and the scanners 140 are still fixedly disposed relative to the reagent pans 120. However, the number of the position codes 150 is plural, and the number of the position codes 150 is equal to the number of the carrying bits 111, so that the position codes 150 and the carrying bits 111 form a one-to-one correspondence relationship. The position code 150 may be arranged directly on the carrier 110 such that the position code 150 follows the carrier 110 with a relative movement. In view of the fact that each of the carrying positions 111 is provided with one position code 150, the relative position between the one-to-one position code 150 and the carrier 110 is always constant during the movement of the carrier 110. Thus, the scanner 140 and the position code 150 form a one-to-many relationship.

For convenience of description, the two different carrying bits 111 are respectively referred to as a first carrying bit and a second carrying bit, and the two different position codes 150 are referred to as a first position code and a second position code, the first position code corresponds to the first carrying bit, and the second carrying bit corresponds to the second position code. When the first carrying bit is in front of the barcode scanner 140 and in an empty state, the barcode scanner 140 may identify the first location code; when the second carrying bit is in front of the barcode scanner 140 and in a vacant state, the barcode scanner 140 can identify the second location code.

Therefore, similar to the embodiment in which the number of the position codes 150 is one, for the embodiment in which the number of the position codes 150 is plural, when the position code 150 cannot be recognized by the scanner 140, it is determined that the carrying position 111 corresponding to the position code 150 is a full position, and the carrier 110 is intermittently moved so that the sample positions 121 in the sample rack 120 are sequentially moved to the position right in front of the scanner 140, so that the sample codes are sequentially recognized and read. When the position code 150 can be identified by the barcode scanner 140, the carrying position 111 corresponding to the position code 150 is determined to be an empty position, so that the carrying member 110 continuously moves to drive the empty position to leave the barcode scanner 140 in a short first time, and thus, it can be ensured that only a short waiting time is required for identifying and reading the sample code on the full position, and finally, the testing efficiency of the whole testing apparatus 10 is improved.

The following test method may be formed by the test apparatus 10, and it is understood that the test method may be completed by the test apparatus 10, that is, the test method may be applied to the test apparatus 10, and the main steps of the test method are as follows:

s210, the carrier 110 is moved so that the sample tube follows the carrier 110. (ii) a

S220, enabling the bearing bit 111 to be within the identification range of the code scanner 140, enabling the position code 150 to be arranged corresponding to the bearing bit 111, and aiming at the bearing bit 111 corresponding to the position code 150; when the position code 150 can be identified by the code scanner 140, the carrying bit 111 is determined as an empty position where the sample rack 120 does not exist; when the position code 150 cannot be identified by the barcode scanner 140, the carrying bit 111 is determined to be a full bit of the sample rack 120. And S230, during the movement of the bearing member 110, the empty position is subjected to a first time from entering to leaving the identification range of the code scanner 140, and the full position is subjected to a second time from entering to leaving the identification range of the code scanner 140, wherein the first time is less than the second time.

Other specific steps of the testing method can refer to the related description of the specific structure and the operation principle of the testing device 10, and are not described herein again.

The invention also provides another testing method, which mainly comprises the following steps:

the carrier 110 is moved so that the sample code on the sample tube moves with the carrier 110.

With the scanner 140 being used to identify the designated sample code.

When the scanner 140 identifies one of the designated sample codes, the scanner 140 passes over the other non-designated sample codes that do not need to be identified, thereby identifying the next designated sample code.

In fact, a new control program may be added to the controller of the testing apparatus 10, specifically, the sample code to be tested is calibrated, so as to calibrate the sample bit 121 corresponding to the sample code, and the calibration information is input to the control program of the controller. In operation, the sample bits 121 corresponding to one of the sample codes are moved to the front of the scanner 140, so that the scanner 140 identifies and reads the sample code. After the identification and reading of the sample code are completed, the carrier 110 is directly driven to move continuously and the sample bit 121 corresponding to the next sample code is moved to the front of the scanner 140, so that the scanner 140 identifies and reads the sample code. And so on, finally enabling the code scanner 140 to identify and read all the sample codes to be tested. Therefore, the sample bits 121 corresponding to the sample code to be tested are marked as the sample bits 121 to be tested, so that the bearing bits 111 continuously move between two adjacent sample bits 121 to be tested, and the other sample bits 121 between the two sample bits 121 to be tested are prevented from pausing in front of the code scanner 140, thereby eliminating the pause time of the bearing member 110 rotating by the radian between two adjacent sample bits 121 to be tested, reducing the waiting time of the sample code to be tested, and also improving the testing efficiency.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
