Description

Technical Field

[0001] This invention belongs to the field of laboratory technology, specifically a convenient combination device for preserving and cleaning laboratory samples. Background Technology

[0002] In medical laboratories, specimen handling and storage are crucial. Proper specimen handling and storage techniques ensure specimen quality and guarantee the accuracy of experimental results. Specimen storage conditions directly affect the accuracy of results; therefore, appropriate storage conditions must be chosen. Blood specimens should generally be stored in a refrigerator at 4 degrees Celsius, avoiding prolonged exposure to room temperature. Urine specimens can be stored at room temperature, but the storage time should not be too long. Storage conditions for other types of specimens should also be selected based on specific requirements. The storage time for specimens should be determined according to the specific needs of the laboratory. Generally, blood specimens should not be stored for more than 72 hours, and urine specimens should not be stored for more than 24 hours. Specimens exceeding the storage time may produce false positive or false negative results, affecting the accuracy of diagnostic results.

[0003] Once a sample has been tested and is no longer needed, it must be disposed of as waste. The reagent tubes and other containers used to hold the samples must then be further cleaned and sterilized for future use. Traditionally, sample storage and cleaning of the containers are performed using separate devices, which is cumbersome. Existing technologies combine these two functions into a single device for both sample storage and cleaning. However, most of these devices are set up with two separate chambers for cleaning containers and storing samples. After cleaning, the sample containers must be removed and stored before other sample containers can be cleaned. However, when conducting large-scale sampling and cleaning outdoors, there is no suitable sterile place to store the cleaned containers. If the cleaned containers are removed and placed elsewhere, they may become contaminated with other bacteria during transportation. Therefore, it is necessary to propose a convenient combined sample preservation and cleaning device for laboratory use that can simultaneously store samples and clean the sample storage containers. Summary of the Invention

[0004] To address the problem of sample containers easily becoming contaminated with bacteria after being moved and cleaned, the present invention aims to provide a convenient sample preservation and cleaning combination device for laboratory use, which can reduce the possibility of bacterial contamination during the random movement of cleaned sample containers, thereby reducing the possibility of subsequent samples being contaminated by other substances.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A convenient combination device for preserving and cleaning samples in the laboratory includes a box, a handle fixedly connected to the top of the box, a partition plate inside the box that divides the inside of the box into a preservation chamber and a cleaning chamber, a cleaning component inside the cleaning chamber, and retrieval outlets on both sides of the box, each retrieval outlet having a sealing door.

[0006] The cleaning assembly includes a cleaning plate, which is fixedly connected to the cleaning chamber. The inner side of the cleaning plate has symmetrical grooves for placing test tubes. The inner side of the grooves has an elastic layer. Several transport wheels are also provided on one side of the two grooves. The transport wheels are coaxially fixedly connected to a rotating shaft. The rotating shaft extends into the cleaning plate and is fitted with a conveyor belt. A cleaning cylinder is fixedly connected to the outside of the transport wheels. The cleaning cylinder has several bristles. A cleaning frame is fixedly connected to the side of the cleaning plate near the partition plate. Several openings are provided at the bottom of the cleaning frame.

[0007] The top and bottom of the cleaning chamber are equipped with several rewash nozzles, which are connected to a liquid storage tank through connecting pipes. The liquid storage tank is located inside the inner wall of the chamber.

[0008] The inner wall of the storage chamber is equipped with several semiconductor cooling chips. The storage chamber is equipped with a sample storage rack and a reagent tube storage rack. Both the sample storage rack and the reagent tube storage rack are fixedly connected to the inside of the box, and the reagent tube storage rack is located above the sample storage rack. A reagent tube moving component is located above the reagent tube storage rack, and an opening and closing component is located on the partition plate near the reagent tube moving component.

[0009] The basic principle is as follows: placing the sample in the storage chamber preserves the sample. When the reagent tube containing the sample needs to be cleaned, the reagent tube is placed in the groove, the conveyor belt is started, and the cleaning cylinder rotates. Under the rotation of the cleaning cylinder, the reagent tube moves along the groove. As the reagent tube moves, the bristles on the cleaning cylinder continuously rotate and contact the outer wall of the reagent tube, cleaning it. Under the rotation of the cleaning cylinder, the reagent tube moves into the cleaning frame. The rewash nozzle is then started, spraying cleaning solution to disinfect and clean the reagent tube accordingly. The cleaned reagent tube is then moved from the cleaning frame to the reagent tube storage rack for storage via the reagent tube moving assembly.

[0010] The beneficial effects of the basic solution are: 1. Compared with the existing equipment that separates sample preservation and cleaning, this device can integrate storage and cleaning, thereby enabling convenient storage and cleaning of reagent tubes and reducing the possibility of other contaminants adhering to the reagent tubes during their movement.

[0011] 2. Compared with the existing technology where cleaning and storage are integrated, the present invention can store the cleaned reagent tubes in separate chambers, thereby realizing that the sample, cleaning and the cleaned reagent tubes are all stored in independent chambers, thus reducing the possibility of bacterial infection between chambers.

[0012] 3. In this invention, the transportation, cleaning and storage of reagent tubes can be conveniently achieved, reducing the tedious operation of manually taking the reagent tubes in and out, thereby increasing the convenience of the device.

[0013] Furthermore, part of the output shaft of the conveyor belt extends into the cleaning plate. A pressure sensor is provided on the cleaning cylinder corresponding to this part of the conveyor belt. The pressure sensor signal is connected to a controller. A cam is coaxially fixedly connected to the output shaft of the conveyor belt extending into the cleaning plate. A liquid chamber is provided between the symmetrically arranged conveyor belts. The liquid chamber is located inside the cleaning plate. Pressurization channels are connected to both sides of the liquid chamber. A piston is provided in each pressurization channel. A piston rod is fixedly connected to the side of the piston away from the liquid chamber. Several tension springs are fixedly connected to the side of the piston near the piston rod. The other end of the tension spring is fixedly connected to the inner wall of the pressurization channel.

[0014] Two infusion tubes are connected to the bottom of the liquid chamber. Each infusion tube is equipped with a silicone one-way cross valve. The infusion tubes extend to the bottom of symmetrical grooves. A cleaning nozzle is located at the bottom of the infusion tube, and a solenoid valve is installed on the cleaning nozzle.

[0015] The beneficial effects of the basic scheme are: under the action of the conveyor belt rotation, the cam rotates, the cam squeezes the piston rod, the piston rod moves to one side of the liquid chamber, the plug moves accordingly, the air pressure inside the liquid chamber changes, the silicone one-way cross valve opens under the action of this air pressure, the cleaning fluid flows into the infusion tube, at this time the opening of the reagent tube is just above the cleaning nozzle, the cleaning fluid can be sprayed into the inside of the reagent tube for thorough cleaning.

[0016] Because only the output shaft of some conveyor belts is equipped with cams, the cleaning solution inside the reagent tube can stay for a certain period of time to dissolve the stains inside the test tube. When the cleaning solution is almost completely drained by gravity, it can be sprayed out by the next cleaning nozzle to clean the reagent tube. This allows for flexible and resource-saving cleaning, ensuring a more thorough cleaning of the reagent tube.

[0017] Furthermore, the groove is a wavy arc shape, and the conveyor belt output shaft equipped with cams consists of three sets, with the three sets of cams located at the highest point of the groove and the lowest points on both sides, respectively.

[0018] The beneficial effects of the basic solution are as follows: When the reagent tube moves under the action of the cleaning cylinder, the movement path of the reagent tube is arc-shaped. When the reagent tube falls down from the highest point of the groove, the cleaning fluid inside the reagent tube can be shaken during this process, thereby increasing the impact force of the cleaning fluid in the reagent tube, thus achieving a more thorough cleaning of the inside of the reagent tube; and under the action of shaking, the cleaning fluid sprayed by the previous cleaning nozzle can fall out of the reagent tube more quickly. Therefore, when the cleaning fluid is sprayed into the reagent tube in the next cycle, it can reduce the residual contaminants from the previous cleaning and thus reduce the risk of cross-contamination.

[0019] Furthermore, the opening and closing assembly includes an opening on the partition plate, a closing plate is closed over the opening, an electric control cylinder is fixedly connected to the top of the closing plate, the output shaft of the electric control cylinder is coaxially fixedly connected to the top of the closing plate, and the cylinder body of the electric control cylinder is fixedly connected to the top of the housing.

[0020] The beneficial effects of the basic scheme are: when the electric control cylinder is activated, the sealing plate moves upward under the action of the electric control cylinder, the opening opens, and the subsequent reagent tube moving assembly can directly take the cleaned reagent into the storage chamber.

[0021] Furthermore, the reagent tube moving assembly includes a motor, which is fixedly connected to one side of the housing. The output shaft of the motor is fixedly connected to a lead screw, which extends through the side wall of the housing into the storage chamber. A nut seat is threaded onto the lead screw, and an inverted "Z"-shaped connecting rod is fixedly connected to the bottom of the nut seat. A connecting cap is fixedly connected to the end of the connecting rod away from the nut seat, and the connecting cap can contact the reagent tube.

[0022] A negative pressure pump is fixedly connected to the top of the box. The negative pressure pump is connected to a gas delivery hose. The gas delivery hose extends into the storage chamber and extends to the connecting cap, and is located on the top of the connecting cap. The gas delivery hose can output negative pressure gas to the inside of the connecting cap.

[0023] The beneficial effects of the basic solution are as follows: When the motor is started, the lead screw rotates, the nut seat moves laterally, and the connecting rod and connecting cap extend through the opening to the top of the cleaning frame. When the negative pressure pump is turned on, the reagent tube can be sucked to the connecting cap under the action of negative pressure suction. The lead screw is then started to rotate in the opposite direction and move the nut seat to one side of the storage chamber. When it is moved to the appropriate position, the negative pressure pump gradually decreases until the suction disappears, thus placing the reagent tube in the appropriate position for storage. This enables convenient movement and storage of the reagent tube, reducing the need to take the reagent tube to the outside for storage, which increases the risk of bacterial infection.

[0024] Furthermore, a partition plate is fixedly connected between the sample storage rack and the reagent tube storage rack, and the side walls of the partition plate are fixedly connected to the inner wall of the box.

[0025] The beneficial effect of the basic scheme is that by setting up the isolation plate, the sample storage rack and the reagent tube storage rack can be separated, thereby reducing the impact of external bacteria and other contaminants on the stored samples.

[0026] Furthermore, filter plates are fixedly connected to the lower parts of both the storage chamber and the cleaning chamber. The filter plates are provided with a number of filter holes. A connection port is provided at the lower part of the partition plate. The connection port is located below the filter plate and can connect the storage chamber and the cleaning chamber. A liquid pump is connected to the connection port.

[0027] The beneficial effects of the basic solution are: the water used to clean the reagent tubes will flow to the bottom of the filter plate, while the wastewater treatment pack can purify the wastewater. After treatment, the liquid pump is turned on, and the treated wastewater moves to the storage chamber. The partition can isolate the wastewater from the upper storage reagent tubes to reduce cross-contamination of bacteria. Subsequently, the treated wastewater can be taken out for testing to see if it meets the discharge standards. If it meets the discharge standards, it is discharged directly. If it does not meet the standards, it is treated again until it reaches the reasonable discharge standards and is discharged.

[0028] Furthermore, protective covers are provided on the electric cylinder, negative pressure pump, and motor.

[0029] The beneficial effects of the basic solution are: the protective sleeve design can protect the electric control cylinder, negative pressure pump and motor, and reduce the damage to the external environment when the box is moved for use. Attached Figure Description

[0036] Example 1

[0037] The basics are as follows: Figures 1-4 As shown: A convenient sample preservation and cleaning combination device for laboratory medicine includes a box 1, a handle 6 fixedly connected to the top of the box 1, a partition 40 inside the box 1, the partition 40 dividing the inside of the box 1 into a preservation chamber and a cleaning chamber, a cleaning component inside the cleaning chamber, and an retrieval outlet on both sides of the box 1, each retrieval outlet being equipped with a sealing door 3.

[0038] The cleaning assembly includes a cleaning plate 2, which is fixedly connected to the cleaning chamber. The inner side of the cleaning plate 2 is symmetrically provided with grooves 28 for placing test tubes. The inner side of the grooves 28 is provided with an elastic layer. Several transport wheels are also provided on one side of the two grooves 28. The transport wheels are coaxially fixedly connected to a rotating shaft. The rotating shaft extends into the cleaning plate 2 and is fitted with a conveyor belt. A cleaning cylinder 29 is fixedly connected to the outside of the transport wheels. Several bristles 30 are provided on the cleaning cylinder 29. A cleaning frame 26 is fixedly connected to the side of the cleaning plate 2 near the partition plate 40. Several openings 27 are provided at the bottom of the cleaning frame 26.

[0039] The cleaning chamber is equipped with several rewash nozzles 5 at the top and bottom. The rewash nozzles 5 are connected to a liquid storage tank through connecting pipes. The liquid storage tank is located inside the inner wall of the chamber 1.

[0040] The inner wall of the storage chamber is provided with several semiconductor cooling chips. The storage chamber is provided with a sample storage rack 20 and a reagent tube storage rack 18. The sample storage rack 20 and the reagent tube storage rack 18 are both fixedly connected to the inside of the box body 1. An isolation plate 19 is fixedly connected between the sample storage rack 20 and the reagent tube storage rack 18. The side walls of the isolation plate 19 are all fixedly connected to the inner wall of the box body 1. The reagent tube storage rack 18 is located above the sample storage rack 20. A reagent tube moving component is provided above the reagent tube storage rack 18. An opening and closing component is provided on the partition plate 40 near the reagent tube moving component.

[0041] The specific implementation process is as follows: When preserving the sample, open the sealed door 3 at the preservation chamber and place the reagent tube containing the sample on the sample preservation rack. The semiconductor cooling chip can control the temperature inside the preservation chamber, thereby enabling the sample to be conveniently preserved at low temperature.

[0042] When cleaning reagent tubes, open the closed door 3 at the cleaning chamber, place the reagent tube in the groove 28, and start the conveyor belt. Driven by the conveyor belt, the cleaning cylinder 29 can rotate. When the cleaning cylinder 29 rotates, the reagent tube can move along the groove 28 under the rotation of the cleaning cylinder 29. When the reagent tube moves, the bristles on the cleaning cylinder 29 can continuously rotate and contact the outer wall of the reagent tube to clean it. At the same time, under the rotation of the cleaning cylinder 29, the reagent tube can move into the cleaning frame 26. At this time, start the rewash nozzle 5. The rewash nozzle 5 will spray cleaning solution to disinfect and clean the reagent tube accordingly. After cleaning, the opening and closing component on the partition plate 40 is opened. At the same time, the reagent tube moving component moves the cleaned reagent tube from the cleaning frame 26 to the reagent tube storage rack 18 for storage. This realizes the transfer, cleaning and storage of reagent tubes. The whole process can be carried out in the box 1 in a convenient and easy manner. Meanwhile, because the reagent tubes are inserted and transported from the grooves on both sides, different test tubes can be input through separate channels, reducing the possibility of cross-infection. The dual-channel design can also increase the cleaning capacity of each test tube, making it suitable for environments with large-scale sampling.

[0043] Example 2

[0044] The difference from the above embodiment is that part of the output shaft of the conveyor belt extends into the cleaning plate 2. A pressure sensor is provided on the cleaning cylinder 29 corresponding to this part of the conveyor belt. The pressure sensor signal is connected to the controller. A cam 34 is coaxially fixedly connected to the output shaft of the conveyor belt extending into the cleaning plate 2. A liquid chamber 33 is provided between the symmetrically arranged conveyor belts. The liquid chamber 33 is located in the cleaning plate 2. Both sides of the liquid chamber 33 are connected to a pressurization channel 32. A piston 37 is provided in each pressurization channel 32. A piston rod 35 is fixedly connected to the side of the piston 37 away from the liquid chamber 33. The piston rod 35 can contact the cam 34. Several tension springs 36 are fixedly connected to the side of the piston 37 near the piston rod 35. The other end of the tension spring 36 is fixedly connected to the inner wall of the pressurization channel 32.

[0045] Two infusion tubes 39 are connected to the bottom of the liquid chamber 33. Each infusion tube 39 is equipped with a silicone one-way cross valve 38. The infusion tubes 39 extend to the bottom of the symmetrical grooves 28. A cleaning nozzle 4 is provided at the end of the infusion tube 39 located below the grooves 28. A solenoid valve is provided on the cleaning nozzle 4.

[0046] The specific implementation process is as follows: When the reagent tube moves to the position of the conveyor belt output shaft, the pressure sensor will receive the corresponding pressure signal. The pressure sensor will transmit the pressure information to the sub-controller. After receiving the information, the controller starts the solenoid valve. Under the action of the conveyor belt output shaft rotation, the cam 34 rotates, and the cam 34 can contact and squeeze the piston rod 35. The piston rod 35 moves to the side of the liquid chamber 33, and the piston 37 moves accordingly. Under the action of the movement of the piston 37, the air pressure inside the liquid chamber 33 changes. The silicone one-way cross valve 38 can open under this air pressure, and the cleaning fluid can then flow to the infusion tube. Within 39, the subsequent series of reactions only occur when the reagent tube moves to the output shaft of the conveyor belt. At this time, the opening of the reagent tube is located above the cleaning nozzle 4, so the cleaning solution can be sprayed into the interior of the reagent tube, and the interior of the reagent tube can be cleaned relatively thoroughly. At the same time, because only part of the conveyor belt output shaft is equipped with a cam 34, the cleaning solution inside the reagent tube can stay for a certain period of time to dissolve the stains inside the test tube. When the cleaning solution is almost completely drained by gravity, it can be sprayed out by the next cleaning nozzle 4 to clean the reagent tube. This achieves flexible and resource-saving cleaning, and ensures a more thorough cleaning of the reagent tube.

[0047] Example 3

[0048] The difference from the above embodiment is that the groove 28 is a wavy arc shape, and the conveyor belt output shaft with cams 34 is three sets, with the three sets of cams 34 located at the highest point and the lowest points on both sides of the groove 28, respectively.

[0049] The specific implementation process is as follows: Because the groove 28 is arc-shaped, when the reagent tube moves under the action of the cleaning cylinder 29, the movement path of the reagent tube is arc-shaped. As a result, when the reagent tube falls from the highest point of the groove 28, the reagent tube itself will produce irregular movement amplitude changes under the action of the height difference. As a result, the cleaning liquid inside the reagent tube can be shaken inside the reagent tube during this process, thereby increasing the impact force of the cleaning liquid on the reagent tube, thus achieving a more thorough cleaning of the inside of the reagent tube.

[0050] Example 4

[0051] The difference from the above embodiments is that the opening and closing assembly includes an opening provided on the partition plate 40, a closing plate 9 is closed on the opening, an electric control cylinder 8 is fixedly connected to the top of the closing plate 9, the output shaft of the electric control cylinder 8 is coaxially fixedly connected to the top of the closing plate 9, the cylinder body of the electric control cylinder 8 is fixedly connected to the top of the housing 1, and a protective sleeve is provided on the outside of the electric control cylinder 8.

[0052] The specific implementation process is as follows: When it is necessary to move the reagent tube after cleaning, the electric control cylinder 8 is turned on. Under the action of the electric control cylinder 8, the sealing plate 9 moves upward and opens, so that the reagent tube moving component can directly take the cleaned reagent into the storage chamber.

[0053] Example 5

[0054] The difference from the above embodiments is that the reagent tube moving assembly includes a motor 16, which is fixedly connected to one side of the housing 1. The output shaft of the motor 16 is fixedly connected to a lead screw 17, which extends through the side wall of the housing 1 into the storage chamber. A nut seat 13 is threaded onto the lead screw 17. An inverted "Z"-shaped connecting rod 14 is fixedly connected to the bottom of the nut seat 13. A connecting cap 12 is fixedly connected to the end of the connecting rod 14 away from the nut seat 13. The connecting cap 12 can contact the reagent tube.

[0055] A negative pressure pump 11 is fixedly connected to the top of the housing 1. The negative pressure pump 11 is connected to a gas delivery hose. The gas delivery hose extends into the storage chamber and extends to the connecting cap 12, and is located on the top of the connecting cap 12. The gas delivery hose can output negative pressure gas to the inside of the connecting cap 12. The negative pressure pump 11 and the motor 16 are provided with protective sleeves.

[0056] The specific implementation process is as follows: When moving the cleaned reagent tube, first start the motor 16. Driven by the motor 16, the lead screw 17 rotates, and then the lead screw 17 and the nut seat 13 form a ball screw 17 structure. Therefore, the nut seat 13 moves laterally, and then the connecting rod 14 and the connecting cap 12 extend through the opening to the top of the cleaning frame 26. At this time, the connecting cap 12 is aligned with the tail of the reagent tube, and the negative pressure pump 11 is turned on. Under the action of the negative pressure pump 11, a corresponding negative pressure is generated inside the connecting cap 12, and the reagent tube can be sucked to the connecting cap 12 under the action of negative pressure suction. When the reagent tube is sucked to the connecting cap 12, the lead screw 17 is directly started to rotate in the opposite direction and the nut seat 13 is moved to the storage chamber side. After moving to the appropriate position, the negative pressure pump 11 is slowly reduced until the suction disappears, so that the reagent tube is placed in the appropriate position for storage. This enables convenient movement and storage of the reagent tube, reducing the need to take the reagent tube to the outside for storage, which would increase the risk of bacterial infection.

[0057] Example 6

[0058] The difference from the above embodiment is that a filter plate 24 is fixedly connected to the lower part of the cleaning chamber, and a wastewater treatment pack 41 is provided at the bottom of the cleaning chamber. The filter plate 24 has a plurality of filter holes 25. A connection port 22 is provided at the lower part of the partition plate 40. The connection port 22 is located below the filter plate 24 and can connect the storage chamber and the cleaning chamber. A liquid pump 23 is connected to the connection port 27. A partition plate 21 is provided at the lower part of the storage chamber and is located above the connection port 22. Bleaching powder or sodium dichloroisocyanurate can be placed in the wastewater treatment pack 41.

[0059] The specific implementation process is as follows: When cleaning the reagent tubes, the cleaning water will flow to the bottom of the filter plate 24. At the same time, the sewage treatment package 41 can purify the sewage. After treatment, the liquid pump 23 is turned on. Under the action of the liquid pump 23, the treated wastewater can be moved to the storage chamber. The partition 21 can isolate the wastewater from the upper storage reagent tube to reduce cross-infection of bacteria. Subsequently, the treated sewage can be taken out for testing to see if it meets the discharge standards. If it meets the discharge standards, it is discharged directly. If it does not meet the standards, it is treated again until it reaches the reasonable discharge standards and is discharged.
