According to the invention, by changing the stress relation between the electromagnet and the permanent magnet, a sample can be taken and placed on the premise that the hand of a user does not enter the storage device, so that the possibility of the sample in the device being polluted is reduced. Meanwhile, when the sample is taken, the sample storage box where the target sample is located is only moved out, and other sample storage boxes are not exposed at the taking port, so that the possibility of sample pollution is further avoided. The invention is convenient for users to take and place samples by the way of rotating the shelf, has large capacity and simple and convenient operation, and can improve the efficiency of users.

According to a preferred embodiment, the electromagnet on the first surface in the sample storage slot pushes the sample storage box to move out quickly when being electrified, and the electromagnet on the first surface in the sample storage slot pushes the sample storage box to move in quickly when being electrified, and the first magnetic layer coated on the horizontal second surface of the sample storage box and the second magnetic layer coated on the opposite second surface of the sample storage slot keep balance with the gravity of the sample storage box in a manner of homopolar repulsion, so that the sample storage box is arranged in an approximately suspended manner in the horizontal direction. Compared with the technical means of mechanically moving the sample storage box in the prior art, the speed of moving the sample storage box in an electromagnetic suspension mode is higher. A disadvantage of mechanically moving the magazine and controlling its speed is that although the magazine can be moved at a predetermined speed, in the case of a moving carousel, the mechanical device needs to be provided with more sensing means and is affected by centripetal force, the mechanical parts are easily dislocated over a long period of time, and the weight of the carousel increases and the rotation becomes difficult, increasing the difficulty of rotation and power consumption. The sample storage box is arranged by adopting electromagnetic induction, the gravity influence of the sample storage box on the rotary table is reduced by the suspension force, the load of the rotary table is reduced, and the service life of the rotary table is prolonged.

Because the sample quantity and the sample weight in the sample storage box can be changed, the friction force between the sample storage box and the sample storage groove can be changed, and the moving acceleration can be changed accordingly. The sample magazine is not always maintained in a balanced condition. Therefore, the acceleration is changed by adjusting the force between the electromagnet and the permanent magnet, the influence of the speed on the sample is reduced to the minimum, and the storage of the sample is facilitated. Even if the sample is in a sealed state, some samples need to be kept still to avoid large-amplitude shaking, and some samples are not affected by shaking.

Preferably, the temperature sensor is preferably a wireless temperature sensor to facilitate movement of the cartridge. More than one sample is present in the cartridge. When the magazine is removed, other samples may be contaminated and the temperature may affect the quality of the samples if the time is too long. If only the time for removing the sample storage box is limited, it cannot be excluded that the sample is affected by an inappropriate temperature. Therefore, the moving-out time is determined according to the temperature change of the sample, so that the influence of improper temperature on the sample can be eliminated, the moving-out time of the sample storage box can be limited, and the unstable temperature of the sample caused by long-time operation of a user can be avoided.

Preferably, the turntable 23 is provided with a plurality of first handles 25. The first ends of the first handles 25 are each provided with a label 24. The label 24 is used to identify the corresponding sample storage box 4, so that the user can quickly find the target sample. The cover 20 is provided with an indicator block 26. Preferably, the cross-section of the indicator block 26 is diamond-shaped. Preferably, the indicator block 26 is adhesively attached to the lid 20. The indication block 26 is arranged to indicate the user to definitely take and place the sample, so that the working efficiency is improved. As shown in fig. 2, preferably, the rack 10 is provided with a plurality of sample storage grooves 11. Preferably, in the polygonal cross-sectional view of the rack 10, the sample storage grooves 11 are equally divided according to the polygonal angle, for example, when the rack is hexagonal, the boundary surface is hexagonal, and the sample storage grooves are triangles equally divided around the center of the hexagonal shape. The sample storage grooves 11 are all provided with sample storage boxes 4. Preferably, the sample storage box is matched with the sample storage groove in shape. Preferably, the sample storage box is not triangular, but is isosceles trapezoid with the same angle as the sample storage groove, so that the sample storage box has redundant space with the sample storage groove when moving in, and sharp collision of the sample storage box due to the edge of the sample storage groove is avoided. Preferably, the sample magazine 4 has a plurality of placement holes 7 therein. Preferably, the placement holes 7 are evenly distributed with respect to each other. The placement holes 7 are used for placing the samples. Preferably, the first end and the two vertical sides of the magazine 4 are provided with permanent magnets 36 for driving it to slide in the radial direction of the housing 18. At least one electromagnet 37 is disposed at a position of the article shelf 10 corresponding to the permanent magnet 36. Wherein the intersection of the two ends of the sample storage groove has a larger electromagnet 37. The electromagnet 37 is arranged to generate a repulsive or attractive force with the permanent magnet 36 provided at the first end of the cartridge 4 to drive the cartridge 4 to move in the radial direction of the housing 18. Wherein, preferably, the sample storage box 4 is trapezoidal, and the short end is opposite to the direction of the rotary table, and the long end is moved out of the sampling opening. The outer sides of two vertical waist ends of the sample storage box 4 are respectively provided with a first side end magnetic layer. At least one electromagnet 37 is arranged on the inner side of the two sample storage grooves opposite to the outer sides of the two waist ends which are vertically arranged on the sample storage box 4. The sample storage box 4 and the sample storage groove 11 are opposite in magnetic pole of the permanent magnet 36 which is closest to each other in the longitudinal direction and can generate repulsion action, and the current direction is changed to enable the magnetic pole to be the same and to generate attraction action. Under the condition that the shelf 10 rotates to any direction, at least one sample storage box 4 moves in at a constant speed and/or moves out at a constant speed in a mode of having electromagnetic buoyancy based on the magnetic force change between the permanent magnet 36 and the electromagnet 37. As shown in fig. 1, permanent magnets 36 are nested on both the upper side and the lower side of the sample storage box 4, and permanent magnets 36 are nested on both the upper side and the lower side of the sample storage groove 11, wherein: the permanent magnet 36 on the upper side of the sample storage box 4 and the adjacent end of the permanent magnet 36 on the upper side of the sample storage groove 11 have opposite magnetic poles and generate mutually repulsive acting force. According to the invention, by changing the stress relation between the electromagnet and the permanent magnet, a sample can be taken and placed on the premise that the hand of a user does not enter the storage device, so that the possibility of the sample in the device being polluted is reduced. Meanwhile, when the sample is taken, the sample storage box where the target sample is located is only moved out, and other sample storage boxes are not exposed at the taking port, so that the possibility of sample pollution is further avoided. The invention is convenient for users to take and place samples by the way of rotating the shelf, has large capacity and simple and convenient operation, and can improve the efficiency of users.

Preferably, the sample storage box 4 is pushed to move out rapidly by the homopolar repulsion between the electromagnet in the sample storage groove 11 and the permanent magnet 36 on the outer side surface, namely the first surface, of the short end of the sample storage box 4 under the condition of being electrified. The electromagnet in the sample storage groove 11 and the permanent magnet 36 on the first surface of the sample storage box 4 opposite to the electromagnet in the energized state push the sample storage box 4 to move rapidly.

The second horizontal surface of the sample storage box 4 is the outer side surface of the bottom end of the sample storage box 4. The second surface coated first magnetic layer and the opposing second surface of the sample well 11, i.e. the second magnetic layer coated on the bottom end surface of the sample well, are in homopolar repulsion equilibrium with the gravitational force of the sample magazine 4 such that the sample magazine 4 is disposed in a substantially levitated manner in a horizontal direction. Compared with the technical means of mechanically moving the sample storage box in the prior art, the speed of moving the sample storage box in an electromagnetic suspension mode is higher. A disadvantage of mechanically moving the magazine and controlling its speed is that although the magazine can be moved at a predetermined speed, in the case of a moving carousel, the mechanical device needs to be provided with more sensing means and is affected by centripetal force, the mechanical parts are easily dislocated over a long period of time, and the weight of the carousel increases and the rotation becomes difficult, increasing the difficulty of rotation and power consumption. The sample storage box is arranged by adopting electromagnetic induction, the gravity influence of the sample storage box on the rotary table is reduced by the suspension force, the load of the rotary table is reduced, and the service life of the rotary table is prolonged.

Preferably, the weight of the cartridge 4 is equal to the repulsive force to which its second surface is subjected when the cartridge 4 is empty. The sample storage box 4 is stressed in the longitudinal direction in a balanced manner under the action of magnetic force, so that the sample storage box is convenient to move. And at least one pressure sensor is arranged on the position, which is not overlapped with the first magnetic layer, of the second surface of the sample storage box 4. The pressure sensor is used for determining the pressure in the vertical direction between the sample storage box and the second surface of the sample storage groove.

The data processing unit 54 counts the repulsive or attractive force between the electromagnet 37 and the permanent magnet 36, and the current data of the electromagnet 37 based on the pressure data change monitored by the pressure sensor, a preset friction coefficient, the type of sample. Because the sample quantity and the sample weight in the sample storage box can be changed, the friction force between the sample storage box and the sample storage groove can be changed, and the moving acceleration can be changed accordingly. For example, as the sample in the cartridge increases, the weight increases and the pressure between the cartridge and the sample reservoir increases, thereby increasing the friction. If a uniform acceleration is to be achieved, the attraction or repulsion between the electromagnet and the permanent magnet is increased. The sample magazine is not always maintained in a balanced condition. Therefore, the acceleration is changed by adjusting the force between the electromagnet and the permanent magnet, the influence of the speed on the sample is reduced to the minimum, and the storage of the sample is facilitated. Even if the sample is in a sealed state, some samples need to be kept still to avoid large-amplitude shaking, and some samples are not affected by shaking. Therefore, the sample is moved into the sample reservoir as quickly as possible with respect to the type of sample, minimizing the possibility of contamination. Preferably, the data processing unit further comprises a storage unit for storing the sample category and the speed range that the sample can withstand, the stored historical data of the sample. Preferably, the data processing module is further connected to an information input device for a user to input data such as sample type and sample information. The information input device can be a touch input electronic screen and also can be a mobile phone terminal. Preferably, the mobile phone terminal is connected with the data processing module through a wireless signal. Preferably, the coefficient of friction between the materials is predetermined based on the known material settings. The type of the sample is preset, and based on the relationship between the friction coefficient and the pressure in mechanics and the maximum force associated with the type of the sample, the magnitude of the repulsive force or attractive force between the electromagnet 37 and the permanent magnet 36 can be calculated. According to the electromagnetic induction principle, the magnitude and direction of the current required by the electromagnet can be calculated by the repulsive force or attractive force. That is, the statistical algorithm is preset. After the current magnitude is calculated, the current magnitude is corrected through an error coefficient.

The control unit 55 adjusts the magnitude of the current of the electromagnet 37 based on the current data sent by the data processing unit 54 to adjust the acceleration of the movement in and/or out of the cartridge 4 to control the speed of the cartridge 4 within a threshold range that the sample can withstand. Because the sample quantity and the sample weight in the sample storage box can be changed, the friction force between the sample storage box and the sample storage groove can be changed, and the moving acceleration can be changed accordingly. The sample magazine is not always maintained in a balanced condition. Therefore, the acceleration is changed by adjusting the force between the electromagnet and the permanent magnet, the influence of the speed on the sample is reduced to the minimum, and the storage of the sample is facilitated. Even if the sample is in a sealed state, some samples need to be kept still to avoid large-amplitude shaking, and some samples are not affected by shaking. Therefore, the sample is moved into the sample reservoir as quickly as possible with respect to the type of sample, minimizing the possibility of contamination.

Preferably, the sample storage box 4 is provided with a speed sensor 56. The data processing unit 54 stores actual speed data of the sample storage box 4 fed back by the speed sensor 56 as historical data, and performs error correction and updating of a statistical algorithm according to the historical data. Wherein the updating of the error coefficients is mainly performed. Because the time for moving the sample storage box out or in is short, the real-time correction difficulty is high, and therefore the data correction and the correction and updating of the statistical algorithm have important significance. After the speed of the sample storage box exceeds the threshold range, the data processing module adjusts and updates the sample type, the weight, the statistical algorithm and the error coefficient, so that the speed of the subsequent samples of the same type and weight is within the threshold range. And repeating the steps, so that the data correction can make up for the defects of the stored data and the statistical algorithm thereof.

For example, the sample 0113 is a blood sample, and standing separates the serum from the platelets and is not suitable for vigorous shaking. Serum is typically taken for detection. Therefore, the blood sample can bear the speed in the range of 0.01m/s to 0.04m/s, and the correction error coefficient is +/-0.01. Most samples, including blood samples such as blood, plasma, anticoagulated whole blood, and erythrocytes, are suitable at a rate in the range of 0.01m/s to 0.04 m/s. If the shaking is severe, it may cause the detection to be inaccurate. For example, page 0115 of the sample is a blood sample, which reaches a maximum speed of 0.06m/s during removal. The velocity of 0.06m/s is clearly outside the threshold range. And the data processing module is used for counting the required attractive force or repulsive force again and calculating the corresponding correction current according to the electromagnetic induction principle. And calculating the difference between the corrected current and the actual current to be used as a new correction coefficient. With this repetition, the correction coefficient becomes more and more accurate.

As shown in fig. 1 and 2, the electromagnet is disposed inside the sample well 11, and the electromagnet 37 is in spaced or abutting relation with the permanent magnet 36, i.e., the sample magazine 4, in the radial direction of the housing 18 when the sample magazine 4 is in the storage state. With the electromagnet 37 energized, the cartridge 4 abuts against or moves away from the electromagnet 37 in a manner to slide in the radial direction of the housing 18 based on the magnetic force generated between the electromagnet 37 and the permanent magnet 36. For example, when a user needs to take and place a sample, the user only needs to press the switch, the magnetic pole of the electromagnet 37 is changed to enable the electromagnet to generate a repulsive force effect with the first end portion of the sample storage box 4 or the permanent magnets 36 on the two vertical side surfaces, and the sample storage box 4 is in a storage state, so that the longitudinal stress of the sample storage box 4 is balanced, the friction force between the sample storage box 4 and the sample storage rack 10 is small when the sample storage box 4 is stressed along the radial direction of the shell 18, the sample storage box 4 can smoothly slide out of the sample storage rack 10, an external tool entering device is not needed, and the external pollution source entering device can be effectively blocked when the sample is taken.

Preferably, the contamination-preventive storage device of the present invention further comprises a temperature control mechanism. The temperature control mechanism comprises at least one temperature sensor 39 arranged in the sample storage box 4. The temperature sensor 39 is connected to the control unit 55 in a data-transmitting manner.

When the temperature data of the sample in the sample storage box 4 in the moved-out state fed back by the temperature sensor 39 is close to the temperature threshold of the sample, the control unit 55 controls the early warning device to send out an early warning signal and actively adjusts the current magnitude and direction of the electromagnet 37, so as to control the sample storage box 4 to move into the sample storage tank 11 at a speed within the threshold range that the sample can bear. Because the time for moving the sample storage box out or in is short, real-time correction is unrealistic, so that the correction of data and the correction and updating of statistical algorithms have important significance. After the speed of the sample storage box exceeds the threshold range, the data processing module adjusts and updates the sample type, weight, statistical algorithm and error coefficient, so that the speed of the subsequent samples of the same type and weight is within the threshold range. And repeating the steps, so that the data correction can make up for the defects of the stored data and the statistical algorithm thereof. Preferably, a first partition 15 and a second partition 19 for forming the water storage area II are respectively nested and installed in the shell 18. Preferably, the housing 18 is provided with a pickup port 30 so as to penetrate the housing 18, the second partition 19, and the first partition 15. As shown in fig. 14, it is preferable that the extraction opening 30 includes at least two first plates 301 and at least two second plates 302. The first plate 301 and the second plate 302 form the fetching port 30 in an end-to-end connection manner. Preferably, when the electromagnet 37 is energized, the magazine 4 can be slid to move away from the object taking opening 30 through the electromagnet 37 based on the magnetic pole relationship between the adjacent ends of the permanent magnet 36 and the electromagnet 37 without departing from the object taking opening 30, or the magazine 4 can be slidably inserted into the rack 10 through the object taking opening 30 based on the magnetic pole relationship between the adjacent ends of the permanent magnet 36 and the electromagnet 37. As shown in fig. 14, the access opening 30 has a hollow rectangular parallelepiped shape with both ends open. The bottom surface of the sample storage groove 11 is in the same plane with the first side surface of the first plate 301 in the vertical direction. The access port 30 is used to communicate the interior of the device with the external environment so that the sample storage cassette 4 can be removed from the device for use by a user.

For example, the user may place the sample into the magazine 4 in response to the record label 24. When a target sample is to be found out from the device, the label 24 corresponding to the sample storage box 4 where the target sample is located only needs to be rotated until the label is pointed by the indicating block 26, at the moment, the electrode of the electromagnet 37 is changed to enable repulsive force to be generated between the label and the permanent magnet 36, and then the sample storage box 4 is separated from the device through the fetching port 30 under the action of the repulsive force, at the moment, only one sample storage box 4 needs to be taken out, and samples in other sample storage boxes do not contact with the outside. Preferably, the side of the magazine 4 is provided with a second handle 6. Under the condition that the rotating shaft 12 is acted by external force, the sample storage box 4 can rotate around the central axis of the rotating shaft 12.

Preferably, the number of the first handles 25 is the same as the number of the sample storage grooves 11. Therefore, one label 24 can correspond to one sample storage box 4, so that the samples can be classified clearly and are convenient to take and place. When the sample storage box 4 is pushed by the repulsive force between the sample storage box 4 and the electromagnet 37 to be separated from the device through the fetching opening 30, a user grasps the sample storage box 4 through the second handle 6 to stabilize the sample storage box, and after taking and placing a sample, the current direction in the electromagnet 37 is changed, so that the attraction force action is generated between the electromagnet 37 and the permanent magnet 36. The sample storage box 4 slides and is embedded into the sample storage groove 11 under the action of the attraction force, and the attraction force always exists during the storage process, so that the sample storage box 4 can be fixed by the action of the attraction force, and can overcome the centrifugal force to keep a state of being relatively static with the sample storage groove 11 during the rotation process of the rotating shaft 12. In the process, the hand of the user does not need to enter the device all the time, thereby effectively avoiding the pollution of other stored samples. Meanwhile, the medical user can find the target sample quickly, and the working efficiency of the user is greatly improved.

For example, it is standard that the sample storage case 4 can be taken out from the taking-out opening 30 when the positional distance between the optional switch 47 and the indication block 26 is minimum. Because the sample storage boxes 4 are circumferentially and evenly distributed in the storage area I, only one object taking opening 30 is formed in the storage area I for the sealing effect, the target sample storage box 4 needs to be opposite to the object taking opening 30 in a rotating mode around the central axis of the rotating shaft 12 before being taken, and the position relation between the switch 47 and the indicating block 26 is used as a basis for judging whether the sample storage box 4 is opposite to the object taking opening 30.

In the case where the electromagnet 37 slides to the end of the switch groove 48, the contact 51 can abut against the respective ends of the power supply wire 53 and the magnet wire 52. The switch 47 herein has the primary function of changing the direction of current flow through the electromagnet 37, in addition to the function of connecting the electromagnet 37 to the power source 38, and the operation principle of the switch 47 is similar to that of a two-position four-way reversing valve. The switch 47 can change the direction of current flowing through the electromagnet 37 in a sliding manner so that the magnetic pole of the electromagnet 37 changes based on the direction of current, the electromagnet 37 applies an attractive force or a repulsive force capable of overcoming the static friction force between the sample storage box 4 and the sample storage groove 11 to the sample storage box 4 through the permanent magnet 36 based on the magnetic pole state of the electromagnet, the longitudinal force balance of the sample storage box 4 is not absolute due to different sample storage amounts of the sample storage box 4, and the repulsive force between the electromagnet 37 and the permanent magnet 36 is enough to drive the sample storage box 4 in a full load condition. As shown in fig. 7, the current direction between the electromagnet 37 and the power source 38 in the present state is from left to right through the first portion of the switch 47, i.e., the first wire 49, such that the electromagnet 37 corresponds to one magnetic pole state, and when the switch 47 is slid from right to left such that the second portion thereof, i.e., the second wire 50, communicates the electromagnet 37 and the power source 38, the current direction flowing through the electromagnet 37 corresponds to the other magnetic pole state, from right to left. The magnetic pole state here is south-north pole relationship, for example, when the direction of the current flowing through the electromagnet 37 is from left to right, the right end of the electromagnet 37 is north pole, and the left end is south pole; when the current flowing through the electromagnet 37 is directed from right to left, the right end of the electromagnet 37 is south and the left end is north.

In the process, the cooling water in the water storage area ii enters the water tank 42 through the third connecting pipe 46 and the check valve 45, is cooled by the action of the refrigerant 44, and is injected into the water storage area ii through the first connecting pipe 43 to the pump 41 and the second connecting pipe 40.

Example 3

The power supply 38 is electrically connected to a voltage regulation module 57. The speed sensor 56 and the voltage regulation module 57 are both communicatively coupled to the data processing unit 54. Preferably, the voltage regulating module 57 may be an intelligent voltage stepless regulator, and is electrically connected to the power source 38. For example, at the moment that the sample storage box 4 receives the repulsive force, the sample storage box 4 moves under the action of the repulsive force because the sample storage box is in a suspension state in the horizontal direction, the repulsive force is continuously reduced in the process of gradually departing from the electromagnet 37, and therefore the sample storage box 4 is in an acceleration motion state with the reduced acceleration in the moving process. The voltage regulation module 57 is connected to the power source 38 because the sample is collected substantially in a glass container such as a test tube, and damage to the test tube may be caused by excessive vibration due to excessive speed. Specifically, at the instant when the electromagnet 37 is energized, the sample storage box 4 starts an acceleration motion with a continuously reduced acceleration due to the repulsive force, at this time, the speed sensor 56 arranged on the sample storage box 4 recognizes the acceleration data of the sample storage box 4 and transmits the acceleration data to the data processing unit 54 in real time, when it is predicted that the speed of the sample storage box 4 may be greater than a preset speed value in the moving-out process based on the change of the real-time speed, the data processing unit 54 sends a real-time signal to the voltage adjusting module 57 to adjust the voltage of the power supply 38, so that the magnetic induction intensity of the electromagnet 37 is reduced, the repulsive force effect on the sample storage box 4 is reduced, and the sample storage box 4 is decelerated to a preset speed under the weak friction force effect of the actual. On the contrary, if the speed of the sample storage box 4 is predicted to be smaller than the preset speed value in the moving-out process based on the change of the real-time speed, the whole force of the sample storage box 4 away from the electromagnet 37 is weakened due to the friction force action of the actual environment, and the motion of the sample storage box 4 may be stopped, so that the data processing unit 54 sends a signal to the voltage adjusting module 57 to adjust the voltage of the power supply 38, so that the magnetic induction intensity of the electromagnet 37 is increased, and the repulsive force action on the sample storage box 4 is increased to enable the sample storage box 4 to reach the preset speed value. The principle of operation when re-moving the cartridge 4 into the device is the same as when moving it out, and will not be described further.
