[0002] In drug storage and drug testing, specially designed drug storage devices are usually used to store drugs. These devices can not only protect drugs from the external environment, but also achieve physical isolation between different types or batches of drugs through structures such as internal partitions, thereby avoiding cross contamination. However, although some existing drug storage solutions have been able to meet basic needs to a certain extent, they still have some limitations.

[0003] In the prior art (the patent application with publication number CN112027474A and patent name of intelligent medicine storage shelf), a bottom plate and a shelf body are included, a support plate is provided at the upper end of the bottom plate, a placement plate is provided on the outer surface of the support plate, and a partition structure is provided at the upper end of the placement plate and the bottom plate, and the partition structure includes a connecting strip, a magnetic strip, and a partition plate.

[0004] In the above patent, the design allows users to separate the area size according to actual needs to adapt to the storage requirements of different volumes or quantities of drugs. However, when it comes to liquid drugs, this fixed partition storage method shows some shortcomings. Long-term static storage of liquid drugs may lead to reduced activity of effective substances in drug samples, because liquid drug samples are prone to precipitation, which not only affects the uniformity and stability of the drug itself, but may also have a negative impact on the accuracy of effect evaluation in subsequent experiments or treatment processes.

[0016] A method for storing samples for drug testing, according to a drug separation storage device, comprises the following steps:

[0017] Step 1. When storing solid drug samples, first control the electric telescopic rod to open and drive the positioning head to move up and snap into the positioning seat, then control the double-headed motor to start and drive the positioning seat to rotate forward through the positioning head that is snapped into place, and the positioning seat drives the lead screw to rotate accordingly, and the lead screw drives the four groups of hinges on the lead screw sleeve to slide downward in the slide groove synchronously, and the four groups of hinges drive the four connecting arms to move downward synchronously, while the four guide rails and the guide rail mouths provide sliding support for the four groups of dividers, then the four connecting arms drive the four groups of dividers to slide outward and expand above the four groups of drug storage areas in the double-layer cabinet, so that the four groups of drug storage areas in the double-layer cabinet are exposed, and then Take off the cover plate on the four groups of dividers that have been expanded and in place, and place various solid drug samples in the four groups of exposed drug storage areas and the four groups of dividers that have been expanded and opened, respectively. After the various solid drug samples have been classified and placed, first cover the cover plate on the four groups of dividers, and then control the double-headed motor to drive the positioning seat to rotate in the opposite direction through the positioning head that is clamped in place. Similarly, the four connecting arms drive the four groups of dividers to move inward synchronously until they are reset and moved above the four groups of drug storage areas in the double-layer cabinet and are sealed. First, control the double-headed motor to pause, and then control the electric telescopic rod to close and drive the positioning head to move down and leave the positioning seat to the initial position.

[0018] Step 2, when storing liquid drug samples, first classify the separators containing the liquid drug samples into four groups of placement seats and annular racks, then control the double-headed motor to start and drive the driving synchronous wheel to rotate, and the four groups of limiting wheels cooperate with the limiting transmission of the synchronous belt, and because the wheel diameter of the four groups of driven synchronous wheels is larger than the wheel diameter of the driving synchronous wheel, the driving synchronous wheel drives the four groups of driven synchronous wheels to rotate synchronously at a low speed through the synchronous belt, and the four groups of annular rotating grooves and the limiting rotating racks provide rotation support for the four groups of placement seats, and the four groups of driven synchronous wheels drive the placement seats and annular racks on the four connecting pipes to rotate synchronously at a low speed, and the four groups of placement seats and the annular racks drive the four groups of separators containing liquid drug samples to rotate continuously at a low speed to prevent the liquid drug sample substances in the four groups of separators from precipitating, so that the liquid drug sample substances in the four groups of separators maintain fluid activity;

[0019] Step 3. When storing solid drug samples at low temperatures, first control the refrigerator to start in advance, and the double-headed motor drives the cam frame to rotate. At this time, the closed electric telescopic rod drives the positioning head to be in an idling state. Then, the cam frame drives the piston heads on the four push rod frames to reciprocate in the four groups of cylinder barrels. When the four push rod frames roll to the concave ends of the cam frame under the elastic reset force of the four reset springs, the piston heads on the four push rod frames are in a return suction state in the four groups of cylinder barrels. The turned-on refrigerator supplies cold air into the four groups of four-way valves through the four supply pipes on the five-way pipe in advance, and then the negative pressure suction generated in the four groups of cylinder barrels sucks the cold air supplied to the four groups of four-way valves into them. When the convex end of the cam frame rotates to the four push rod frames, the four return springs on the four push rod frames are forced to be in a compressed state. At this time, the four groups of piston heads are in a process exhaust state in the four groups of cylinder barrels. Then, the cold air in the four groups of cylinder barrels is pressurized and supplied to the four supply heads through the four groups of four-way valves under the extrusion pressure of the four groups of piston heads. This reciprocating process continuously passes the cold air generated by the refrigerator through the flow equalizing plates on the four supply heads, and then passes through the four groups of reserved openings to reach the four groups of medicine storage areas in the double-layer cabinet. The cold air in the four groups of medicine storage areas then passes through the four groups of hollow nets to reach the four groups of separators in a blocked state, so that the solid medicine samples in the four groups of medicine storage areas and the separators can be stored at low temperatures.

[0020] The drug separation storage device and storage method of the present invention have the following advantages:

[0021] 1. This medicine separation storage device and storage method can separate solid medicines and liquid medicines by using separator 1 and separator 2 when storing medicines, so that the medicines can be kept separated from each other.

[0022] 2. This drug partition storage device and storage method, when storing solid drug samples, firstly, a double-headed motor provides a unified driving source, and an electric telescopic rod adjusts the clamping stroke between the positioning head and the positioning seat, and then the lifting and lowering adjustment of the screw rod and the screw rod sleeve cooperates, and the four connecting arms are driven by the hinge to achieve the outward expansion or inward reset adjustment effect of the four groups of dividers. The four groups of dividers can be expanded outward to expose the four groups of drug storage areas in the double-layer cabinet, so that a large number of solid drug samples can be placed in the four groups of dividers and the four groups of drug storage areas in the double-layer cabinet for storage. The four groups of dividers can be reset inward to seal the four groups of drug storage areas in the double-layer cabinet, and then the four groups of cover plates can be used to seal the four groups of dividers to prevent external environmental factors from affecting the four groups of dividers and the solid drug samples stored in the drug storage areas. After meeting the storage needs of large-capacity solid drug samples, the storage time of the solid drug samples is extended, and the efficacy of the solid drug samples is guaranteed.

[0023] 3. This drug separation storage device and storage method, when storing liquid drug samples, is synchronized by a driving synchronous wheel, four sets of limiting wheels and a driven synchronous wheel, and the wheel diameter of the driving synchronous wheel is smaller than the wheel diameter of the driven synchronous wheel, and four sets of annular rotating grooves and a limiting rotating frame provide rotational support for the four sets of placement seats. Then, the four sets of driven synchronous wheels drive the four sets of placement seats and the separators 2 in the annular frame to rotate at a low speed through connecting tubes, so that the liquid drug samples in the four sets of separators 2 remain in a flowing active state, so as to prevent the effective substances in the liquid drug samples in the four sets of separators 2 from precipitating.

[0024] 4. This drug separation storage device and storage method, when providing low temperature conditions for solid drug samples in storage, first provides cold air supply by a refrigerator, and then supplies the cold air into four groups of four-way valves through four supply pipes by a five-way pipe, and at the same time, the cam frame, four push rod frames, piston heads and return springs perform reciprocating work, and generate pressurized gas in four groups of cylinder barrels. Under the action of the boost pressure, the cold air supplied into the four groups of four-way valves is forced to be pressurized and supplied into the four groups of supply heads, and after reaching the four groups of drug storage areas in the double-layer cabinet, the cold air passes through the four groups of hollow nets and reaches the four groups of separators. The solid drug samples stored in the four groups of drug storage areas and separators can be cooled, so that they can be stored at low temperatures for a long time and the material activity of the solid drug samples can be continuously maintained.

[0043] The present invention is specifically described below in conjunction with the accompanying drawings and specific embodiments:

[0044] like Figure 1-Figure 16 As shown, a drug separation storage device of the present invention has a core part of a horizontally placed double-layer cabinet 1. In order to ensure structural stability and supporting force, cabinet legs 2 are installed around the cabinet, and the cabinet legs 2 are independently threaded and adjustable, which not only increases the safety of the entire device, but also ensures that it can be placed stably even on uneven ground. Medicine storage areas are provided on all sides of the double-layer cabinet 1, which can effectively classify and store different types of medicines for easy management and retrieval. It is worth noting that a fixing frame 3 is fixed to the bottom of the double-layer cabinet 1, and this fixing frame 3 is connected to the surrounding cylinder barrels 4. The most direct benefit of adopting this double-layer horizontal design concept is that the height requirement of the entire storage device is significantly reduced, so that medical staff with shorter stature can easily access the required solid medicines and liquid samples from four directions.

[0045] A fixed cylinder 5 is fixedly installed at the top center of the double-layer cabinet 1. A set of adjustment components 6 is arranged around the fixed cylinder 5, and this set of components is closely matched with the medicine storage area. The adjustment component 6 mainly consists of two parts: one is a double-headed motor 61 located at the center of the inner cavity of the double-layer cabinet 1, and the other is a separator 69 that can slide in the medicine storage area. The double-headed motor 61, as a power source, can drive the separator 69 to move in the medicine storage area, meet the storage needs of large-capacity solid medicine samples, extend the storage time of solid medicine samples, and ensure the efficacy of solid medicine samples.

[0046] Around the fixed frame 3, there is a supply assembly 7 that cooperates with the cylinder barrel 4. The main function of this supply assembly 7 is to provide a cold storage environment for the solid drug samples in the drug storage area and the divider 69. Through an effective cooling mechanism, the supply assembly 7 can ensure that the solid drug samples stored in the four groups of drug storage areas and the divider 69 can be stored for a long time under low temperature conditions. This low-temperature storage method not only extends the shelf life of the medicine, but also helps to maintain the material activity of these solid drug samples, avoiding the reduction or failure of the efficacy due to excessive temperature. In addition, in order to ensure the quality of the liquid drug sample, an anti-precipitation assembly 8 is specially arranged around the double-layer cabinet 1. The function of this assembly is to prevent the active ingredients in the liquid drug sample from precipitating. By maintaining the liquid sample in a flowing state, the anti-precipitation assembly 8 can ensure that the effective substances inside the liquid drug are evenly distributed, thereby maintaining its optimal active state.

[0047] like Figure 5-Figure 12 As shown, the adjustment component 6 also includes an electric telescopic rod 62 embedded in an output shaft of a double-headed motor 61. A positioning head 63 is fixed to the piston rod end of the electric telescopic rod 62, and a positioning seat 64 is arranged above the positioning head 63. This structural design enables the entire system to use the double-headed motor 61 as a unified power source, and the electric telescopic rod 62 can accurately control the change in the relative position between the positioning head 63 and the positioning seat 64. Such an adjustment mechanism provides a basis for subsequent actions. A screw rod 65 is connected to the top of the positioning seat 64, and this screw rod 65 is rotatably matched with the fixed cylinder 5. A screw rod sleeve 66 is threadedly connected to the screw rod 65, and a plurality of hinges 67 are evenly distributed and fixed around the screw rod sleeve 66. One end of a connecting arm 68 is installed on each hinge 67, and the other end of these connecting arms 68 is connected to a separator 69 through a hinge seat. When the screw rod 65 rotates, it drives the screw rod sleeve 66 to move up and down, and then promotes the four connecting arms 68 to move through the hinge 67, so as to realize dynamic adjustment of the separator 69 in four directions to expand outward or contract inward.

[0048] The fixed cylinder 5 is designed with slide grooves 10 around it, which cooperate with the hinge 67 to provide sliding support for the hinge 67. Such a design enhances the stability of the hinge 67 during the lifting process and ensures that the entire adjustment process is smooth and stable. A guide bar 11 is installed at the bottom of the separator 69, and a guide rail opening 12 matching the guide bar 11 is set on the side of the double-layer cabinet 1 close to the medicine storage area. This guide rail system not only supports the smooth movement of the separator 69 when it expands outward or resets inward, but also prevents it from shaking or tilting during the movement, thereby ensuring the safety and stability of drug storage. In addition, a cover plate 13 is installed on the outside of the top of the separator 69, and the cover plate 13 can be tightly clamped to the separator 69 to play a blocking role. A pinch ear is provided at the center of the top of the cover plate 13 to facilitate the staff to open and close the cover plate and perform the operation of taking and placing the medicine.

[0049] Hollow nets 14 are embedded on both sides of the bottom of the separator 69. These hollow nets are designed in a triangular shape to ensure the connectivity between the separator 69 and the drug storage area. Such a design allows cold air to flow freely into the separator 69 through the hollow nets 14, thereby ensuring that the solid drug sample is stored in a suitable low-temperature environment, which helps to extend the shelf life of the drug and maintain its activity.

[0050] The double-layer cabinet 1 is staggeredly fixed with partitions around the medicine storage area, and these partitions are used in conjunction with the separators 69 to clearly separate the four groups of separators 69 from the medicine storage area. This layout not only helps to classify and store different types of solid medicine samples, but also improves management efficiency, allowing medical staff to quickly and accurately find the required medicines.

[0051] It is worth noting that the cross-sectional area of ​​the separator 69 is exactly the same as that of the drug storage area. This means that when the separator 69 is in a closed state, it can fit tightly against the top opening of the drug storage area and play a blocking role. In this way, the separator 69 actually acts as a top cover of the drug storage area, forming a sealed space. This sealing design helps to further improve the stability of the storage environment and prevent external factors such as temperature changes, humidity or dust from adversely affecting the quality of the drugs.

[0052] The core component of the supply assembly 7 is a refrigerator 71 fixed to the bottom of the fixed frame 3, which is responsible for generating cold air to maintain the low temperature environment required for the medicine. The bottom end of the refrigerator 71 is connected to a five-way pipe 72, which evenly distributes the cold air to four directions. The four supply pipes 73 coming out of the five-way pipe 72 are respectively connected to four groups of four-way valves 74, which are connected to the cylinder barrel 4 to control the flow of cold air to the medicine storage area.

[0053] A cam frame 75 is mounted on the other output shaft of the double-headed motor 61, and four push rod frames 76 are rollingly connected around the cam frame. A piston head 77 is fixed at one end of each push rod frame 76, and these piston heads are slidably matched with the inside of the cylinder barrel 4. A return spring 78 is also sleeved on the push rod frame 76 so that it can automatically return to its original position after completing a reciprocating motion. Through the coordinated work of the cam frame 75, the push rod frame 76, the piston head 77 and the return spring 78, the system can generate pressurized gas in the cylinder barrel 4.

[0054] When the pressurized gas acts on the four-way valve 74, it forces the cold air previously provided by the refrigerator 71 to be further pressurized and enters the four medicine storage areas in the double-layer cabinet 1 through the supply head 79 at the top. Subsequently, the cold air passes through the hollow mesh 14 arranged on both sides of the bottom of the divider 69 and finally reaches the inside of the divider 69. In this way, not only the solid drug samples in the medicine storage area are effectively cooled, but also the samples in the divider 69 can be kept in a suitable low temperature environment, thereby ensuring that the drugs can be stored for a long time and their material activity can be continuously maintained.

[0055] A reserved opening 15 is designed on one side of the double-layer cabinet 1 near the bottom of the medicine storage area, and a flow equalizer 16 is embedded inside the reserved opening. The flow equalizer 16 is connected and matched with the supply head 79 to ensure that the cold air coming out of the supply head 79 can be evenly distributed to the medicine storage area after flow equalization. The purpose of this design is to avoid turbulence or blockage of the cold air when it enters the medicine storage area, so as to ensure that the cold air can reach every corner smoothly and evenly.

[0056] The flow equalizing plate 16 adopts a circular honeycomb design, which can effectively improve the degree of equalization of the cold air. The honeycomb holes can divide the cold air into multiple small airflows, so that the cold air can be diffused more evenly, reducing the turbulence and uneven distribution problems that may occur when the cold air passes through the reserved opening 15. In this way, not only is the temperature distribution in the drug storage area more uniform, but it can also ensure that the cold air can smoothly pass through the hollow net 14 and further reach the inside of the separator 69, providing a stable low-temperature storage environment for solid drug samples.

[0057] The purpose of the anti-precipitation component 8 is to prevent the active ingredients in the liquid drug sample from precipitating and maintain its flow activity state. The component includes a driving synchronous wheel 81 fixed on the output shaft of the double-headed motor 61 near the cam frame 75. The driving synchronous wheel 81 is connected to the driven synchronous wheels 82 around it through a synchronous belt. The wheel diameter of these driven synchronous wheels 82 is larger than that of the driving synchronous wheel 81 to achieve low-speed rotation. In addition, the inner cavity of the fixed frame 3 is also provided with a limit wheel 83 that cooperates with the synchronous belt to ensure the stable operation of the synchronous belt.

[0058] A connecting tube 84 is embedded inside the driven synchronous wheel 82, and the top end of the connecting tube 84 is connected to the placement seat 85. The placement seat 85 is provided with an annular rotating groove 86, and a limited rotating frame 87 is installed in the annular rotating groove 86. The limited rotating frame 87 is fixedly matched with the double-layer cabinet 1 to provide rotation support for the placement seat 85. The top of the placement seat 85 is connected to an annular frame 88, and the two together constitute the space of the separator 2 89 for storing liquid drug samples.

[0059] When the double-headed motor 61 is started, the driving synchronous wheel 81 drives the four driven synchronous wheels 82 to rotate synchronously at a low speed through the synchronous belt. Since the driven synchronous wheels 82 are connected to the placement seat 85 through the connecting tube 84, they can drive the placement seat 85 and the separator 2 89 in the annular frame 88 above it to rotate slowly together. This low-speed rotation helps to keep the liquid drug sample in the separator 2 89 in a continuous flow state, thereby avoiding the precipitation of the effective substance.

[0060] The outer end of the ring frame 88 away from the placement seat 85 is designed with an arc chamfer. This design not only makes the appearance of the ring frame 88 smoother, but also protects the operator by avoiding accidents such as scratches when inserting or removing the separator 89 into the ring frame 88.

[0061] The top of the separator 89 is connected with a plugging head, which is used to seal the separator 89 and also facilitate the filling of liquid drug samples therein. The plugging head and the separator 89 are connected by threads, which can be quickly disassembled and assembled, making it convenient for medical staff to add and replace drugs. This design ensures sealing and improves operating efficiency.

[0062] In addition, the separator 89 itself adopts a thin-wall design, and can be made of a metal container or a glass container. This choice is mainly to enhance the cold air conduction effect, so that the cold air can be quickly transferred to the liquid drug sample through the container wall, thereby achieving efficient cooling. This efficient cooling is the key to keeping the liquid drug sample at low temperature, which helps to extend the shelf life of the drug and maintain its activity.

[0063] like Fig.12 - Fig.14As shown, during the storage of liquid drug samples, due to the material characteristics of the liquid drug samples, the liquid drug samples do not have a low-temperature preservation function, resulting in the liquid drug samples being affected by the external temperature and deteriorating, affecting the subsequent detection of the liquid drug samples. The outer end of the supply component 7 is provided with an auxiliary component 9 used in conjunction with the anti-precipitation component 8, and the auxiliary component 9 includes a shunt pipe 91 connected to the outer end of the four-way valve 74, and both ends of the shunt pipe 91 are connected to a three-way joint 92, and the top of the three-way joint 92 is connected to a rotating head 93, and the inner cavity of the rotating head 93 is rotatably connected to a connecting head 94 that is connected and matched with the connecting pipe 84, and the rotating head 93 and the connecting head 94 maintain an intercommunication state, and the cold air in the four groups of four-way valves 74 is supplied to the four groups of three-way joints 92 through the four shunt pipes 91, and then supplied to the four connecting pipes 84 by the four groups of rotating heads 93 and the connecting head 94;

[0064] The inner cavity of the placement seat 85 is designed with a flow guiding cavity 95, which is connected to the connecting pipe 84. On the circumference of one side of the placement seat 85 close to the second separator 89, a circle of dense small holes 96 are densely opened, and these small holes are connected to the flow guiding cavity 95. When the cold air enters the flow guiding cavity 95 in the placement seat 85 through the connecting pipe 84, it will be evenly conducted to the bottom area of ​​the second separator 89 through these dense small holes 96.

[0065] The inner cavity of the annular frame 88 is also provided with an extension cavity 97, which is also connected to the guide cavity 95. A plurality of cold delivery ports 98 are also provided around the extension cavity 97 near the second separator 89, and a flow equalization net 99 is embedded in the inner wall of each cold delivery port 98. In this way, the cold air from the guide cavity 95 can further pass through the extension cavity 97 and pass through the flow equalization net 99 in the cold delivery port 98 for flow equalization, ensuring that the cold air can evenly reach the side area of ​​the second separator 89.

[0066] Through this design, cold air not only enters from the bottom of the separator 89, but is also evenly distributed from the side, thereby achieving all-round cooling of the liquid drug sample. This helps to keep the liquid drug sample under suitable low temperature conditions, avoid the deterioration of the active ingredients due to temperature changes, and also maintain the activity of the substances inside. This low-temperature storage method is particularly conducive to subsequent precise testing work, ensuring the quality of the drug and the accuracy of the test results.

[0067] A method for storing samples for drug testing, based on a drug separation storage device, comprises the following steps:

[0068] Step 1. When storing solid drug samples, first control the electric telescopic rod 62 to open and drive the positioning head 63 to move up and snap into the positioning seat 64, then control the double-headed motor 61 to open and drive the positioning seat 64 to rotate forward through the positioning head 63 that is snapped into place, and the positioning seat 64 drives the screw rod 65 to rotate accordingly, and the screw rod 65 drives the four groups of hinges 67 on the screw rod sleeve 66 to slide downward in the slide groove 10 synchronously, and the four groups of hinges 67 drive the four connecting arms 68 to move downward synchronously. At the same time, the four guide rails 11 and the guide rail openings 12 provide sliding support for the four groups of separators 69, and then the four connecting arms 68 drive the four groups of separators 69 to slide outward and expand above the four groups of drug storage areas in the double-layer cabinet 1, so that the four groups of drug storage areas in the double-layer cabinet 1 are exposed, so as to facilitate the relative The corresponding medicines can be put in or taken out, and then the cover plate 13 on the four groups of separators 69 after expansion is taken down, and a variety of solid medicine samples are placed in the four groups of medicine storage areas exposed and the four groups of separators 69 after expansion and opening respectively. After the classification and placement of a variety of solid medicine samples are completed, the cover plate 13 on the four groups of separators 69 is first covered, and then the double-headed motor 61 is controlled to drive the positioning seat 64 to rotate in the opposite direction through the positioning head 63 after being clamped in place. Similarly, the four connecting arms 68 drive the four groups of separators 69 to move inward synchronously until they are reset to the top of the four groups of medicine storage areas in the double-layer cabinet 1 and are blocked. First, the double-headed motor 61 is controlled to pause, and then the electric telescopic rod 62 is controlled to close and drive the positioning head 63 to move down and leave the positioning seat 64 to the initial position;

[0069] Step 2: When storing liquid drug samples, first place the separators 89 containing the liquid drug samples in four groups of placement seats 85 and the annular frame 88, and then control the double-headed motor 61 to start and drive the driving synchronous wheel 81 to rotate, and the four groups of limiting wheels 83 cooperate with the limiting transmission of the synchronous belt. Since the wheel diameter of the four groups of driven synchronous wheels 82 is larger than the wheel diameter of the driving synchronous wheel 81, the driving synchronous wheel 81 drives the four groups of driven synchronous wheels 82 to rotate synchronously at a low speed through the synchronous belt. The four groups of annular rotating grooves 86 and the limit rotating frame 87 provide rotation support for the four groups of placement seats 85, and the four groups of driven synchronous wheels 82 drive the placement seats 85 and the annular frame 88 on the four connecting tubes 84 to rotate synchronously at a low speed. The four groups of placement seats 85 and the annular frame 88 drive the four groups of separators 89 with liquid drug samples to rotate continuously at a low speed to prevent the liquid drug sample substances in the four groups of separators 89 from precipitating, so that the liquid drug sample substances in the four groups of separators 89 can maintain the flow activity;

[0070] Step 3, when the solid drug sample is stored at low temperature, the refrigerator 71 is controlled to be turned on in advance, and the double-headed motor 61 drives the cam frame 75 to rotate. At this time, the closed electric telescopic rod 62 drives the positioning head 63 to be in an idling state, and then the cam frame 75 drives the piston heads 77 on the four push rod frames 76 to reciprocate in the four groups of cylinder barrels 4. When the four push rod frames 76 roll to the concave ends of the cam frame 75 under the elastic reset force of the four reset springs 78, the piston heads 77 on the four push rod frames 76 are in a return suction state in the four groups of cylinder barrels 4, and the refrigerator 71 in the turned-on state supplies the cold air into the four groups of four-way valves 74 through the four supply pipes 73 on the five-way pipe 72 in advance, and then the negative pressure suction force generated in the four groups of cylinder barrels 4 supplies the cold air into the four groups of four-way valves 74. When the cam frame 75 is sucked in, the convex end of the cam frame 75 rotates to the four push rod frames 76, forcing the four return springs 78 on the four push rod frames 76 to be in a compressed state. At this time, the four groups of piston heads 77 are in a process exhaust state in the four groups of cylinder barrels 4. Then, the cold air in the four groups of cylinder barrels 4 is pressurized and supplied to the four supply heads 79 through the four groups of four-way valves 74 under the extrusion pressure of the four groups of piston heads 77. In this way, the cold air generated by the refrigerator 71 is continuously processed by the flow equalizing plates 16 on the four supply heads 79, and then passes through the four groups of reserved openings 15 to reach the four groups of medicine storage areas in the double-layer cabinet 1. The cold air in the four groups of medicine storage areas passes through the four groups of hollow nets 14 and reaches the four groups of separators 69 in a blocked state, so that the solid medicine samples in the four groups of medicine storage areas and the separators 69 can be stored at low temperatures.

[0071] Step 4, when the liquid drug sample is stored at low temperature, the cold air discharged from the four groups of four-way valves 74 is first supplied to the four groups of three-way joints 92 through the four shunt pipes 91, and then passes through the four groups of rotating heads 93 and connecting heads 94 in a rotating and intercommunication state in turn, and reaches the connecting pipe 84 in a rotating state. The cold air is then supplied to the guide cavity 95 of the four groups of placement seats 85 and is conducted to the bottom area of ​​the separator 2 89 by the dense small holes 96. At the same time, the cold air supplied to the guide cavity 95 is conducted to the extension cavity 97 in the annular frame 88, and reaches the side area of ​​the separator 2 89 after being processed by the flow equalization network 99 in the cold delivery port 98. The bottom and side of the four groups of separators 2 89 with liquid drug samples in low-speed rotation can be cooled, and the liquid drug samples in the four groups of separators 2 89 in a low-speed rotating state can be stored at low temperature.

[0072] It should be noted that the specific models and specifications of the double-headed motor 61, the electric telescopic rod 62 and the refrigerator 71 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.
