Description

Technical Field

[0001] The present invention belongs to the technical field of specimen management, and in particular, relates to a specimen management device for molecular pathology detection. Background Art

[0002] Molecular pathology testing is a high-precision, high-sensitivity detection method in the field of pathology. It is a pathological diagnosis technology that uses molecular biology technology to detect molecular genetic changes in cells and tissues at the gene level to assist pathological diagnosis and molecular typing, guide targeted treatment, and judge prognosis. Molecular pathology specimens are non-reproducible and have important value for diagnosis, treatment, and scientific research. Therefore, the requirements for the storage and management of molecular pathology specimens are becoming increasingly higher.

[0003] Currently available patents, such as the patent publication number CN112938180B and the publication date 2022-07-12, disclose a specimen management device for molecular pathology detection, which utilizes the driving action of the single-axis motor and the wind force of the fan rotation to achieve the driving and cleaning action of the connection between the box door and the storage box body during dehumidification work through the coordinated action of a single-axis motor, a driving mechanism, a pneumatic mechanism, a fan, a spring and a traction rope; however, the above-mentioned specimen management device for molecular pathology detection has the following disadvantages when actually used: 1. The wind force generated by the rotation of the dehumidification fan blows the air pressure plate of the same size to squeeze the second spring, and the traction rope is loosened to reset the first spring. In fact, it is only to realize the downward cleaning function of the cleaning brush. The structure is complicated and does not bring any unexpected technical effects.

[0004] 2. When there is a lot of dust, it is difficult for the dehumidification fan to drive the air pressure plate through the wind force of air circulation, so it is not very practical; and if you clean the dehumidification fan after it rotates, the cleaned dust will still be blown away by the wind force generated by the dehumidification fan, and effective cleaning effect cannot be achieved.

[0005] Therefore, in order to store and manage molecular pathology specimens more efficiently, conveniently, safely and scientifically, the present invention designs a specimen management device for molecular pathology testing, which integrates automated processing and environmental control functional modules to adapt to the high-quality development of modern pathology laboratories.

[0035] A specimen management device for molecular pathology detection, such as Figure 1-Figure 8As shown, it includes: a specimen management cabinet 1, on which a cabinet door 11 is hinged, and the cabinet door 11 is located at the front side of the specimen management cabinet 1; a plurality of specimen storage racks 2 are arranged in an up-and-down direction inside the specimen management cabinet 1, and the specimen storage racks 2 slide in the specimen management cabinet 1. By opening the cabinet door 11, specimens to be managed can be taken and placed on different specimen storage racks 2, and the specimen storage racks 2 can be taken and placed more conveniently by moving the specimen storage racks 2 forward; the specimen storage racks 2 are provided with a label pasting frame 20, and by pasting labels on the label pasting frame 20, it is convenient to classify the specimens placed on the label pasting frame 20, and it is also convenient to retrieve the specimens later. ; A plurality of electrically controlled lighting lamps 13 are installed on the left and right inner sides of the specimen management cabinet 1. When lighting is needed, the electrically controlled lighting lamps 13 are turned on to illuminate the label pasting frame 20. When lighting is not needed, the electrically controlled lighting lamps 13 are turned off; a ventilation system 3 is installed on the right side of the specimen management cabinet 1. The circuit of the ventilation system 3 is intermittently switched on and off. The ventilation system 3 is used to keep the inside of the specimen management cabinet 1 dry; the ventilation system 3 includes: an L-shaped ventilation pipe 31 having a first end and a second end. The first end of the ventilation pipe 31 is located inside the specimen management cabinet 1, and the second end of the ventilation pipe 31 is located outside the specimen management cabinet 1 The air inside the specimen management cabinet 1 and the air outside the specimen management cabinet 1 are circulated through the ventilation pipe 31; the ventilation net 1 32 connected to the first end of the ventilation pipe 31 and the ventilation net 2 33 connected to the second end of the ventilation pipe 31, the ventilation net 1 32 and the ventilation net 2 33 will intercept the dust in the air circulating in the ventilation pipe 31, so as to prevent the dust from affecting the ventilation system 3, ensure the normal ventilation and drying work, and prevent the dust from contaminating the specimens; the ventilator 34 is installed inside the ventilation pipe 31, and the ventilator 34 is controlled to start to speed up the circulation of air in the ventilation pipe 31, so as to perform the ventilation and drying work. The cleaning brush 35 is slidably arranged at the second end of the ventilation pipe 31 in a manner of contacting the ventilation net 2 33. The cleaning brush 35 is located above the ventilation net. A resistance sleeve 36 is rotatably arranged on one side of the cleaning brush 35. Before starting the ventilator 34, the cleaning brush 35 is driven downward by the resistance sleeve 36 to clean the dust attached to the ventilation net 2 33. The switch 41 is installed on one side of the specimen management cabinet 1. The switch 41 has a built-in controller electrically connected to the ventilator 34. The ventilator 34 is started by pressing the switch 41. The pressing block 42 is slidably arranged on one side of the specimen management cabinet 1. The pressing block 42 is suitable for moving back and pressing the switch 41.The driving component is installed on the right part of the management cabinet, and the driving component is used to drive the pressing block 42 to move forward and backward. In the first embodiment, when the circuit of the ventilation system 3 is connected, the driving component will drive the pressing block 42 to move backward to press the switch 41 to start the ventilator 34, and when the circuit of the ventilation system 3 is disconnected, the driving component will drive the pressing block 42 to move forward to reset and release the switch 41 to close the ventilator 34, and in the second embodiment, when the circuit of the ventilation system 3 is disconnected, the driving component will drive the pressing block 42 to move backward to press the switch 41 to start the ventilator 34, and when the circuit of the ventilation system 3 is connected, the driving component will drive the pressing block 42 to move forward to reset and release the switch 41 to close the ventilator 34. The use of this embodiment is that when the startup time of the ventilator 34 is required to be greater than the shutdown time of the ventilator 34 When the air conditioner is closed, the circuit of the ventilation system 3 can be disconnected and the ventilator 34 can be started to achieve the effect of energy saving and power saving; the extrusion frame 44 is connected to the pressing block 42, and a strip groove 45 surrounding the contact sleeve 36 is opened on the extrusion frame 44. The extension direction of the strip groove 45 is inclined to the sliding direction of the cleaning brush 35. When the pressing block 42 moves backward, it will first squeeze the contact sleeve 36 downward through the strip groove 45 on the extrusion frame 44, and the contact sleeve 36 will drive the cleaning brush 35 to move downward to clean the ventilation net 2 33. After cleaning, the pressing block 42 continues to move backward and presses the switch 41 to start the ventilator 34, so as to automatically clean first and then ventilate to prevent dust from being blown away by wind. The various steps are interrelated and coordinated with each other, and the structure is simple. It is not driven by wind, and the driving of the cleaning brush 35 is only achieved with the cooperation of the extrusion frame 44 and the contact sleeve 36. ;

[0036] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, for the first embodiment of the ventilation system 3, the driving component includes: a connecting spring 43, connected between the pressing block 42 and the specimen management cabinet 1, the connecting spring 43 is located inside the specimen management cabinet 1, and the connecting spring 43 is used for resetting the pressing block 42 that moves backward; an electromagnet 46, installed on one side of the specimen management cabinet 1, the pressing block 42 is magnetic, and the electromagnet 46 is suitable for magnetically adsorbing the magnetic pressing block 42 after power is turned on. When the circuit of the ventilation system 3 is connected, the electromagnet 46 is also energized and magnetically adsorbs the pressing block 42 to move backward and press the switch 41 to start the ventilator 34, and the connecting spring 43 is deformed. When the circuit of the ventilation system 3 is disconnected, the electromagnet 46 is also powered off and releases the pressing block 42. The pressing block 42 will move forward under the action of the connecting spring 43 to release the switch 41 to turn off the ventilator 34, thereby realizing the automation of drying and ventilation.

[0037] like Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, for the second embodiment of the ventilation system 3, the driving component includes: a connecting spring 43, connected between the pressing block 42 and the specimen management cabinet 1, the connecting spring 43 is located inside the specimen management cabinet 1, and the connecting spring 43 is used for resetting the pressing block 42 that moves forward; an electromagnet 46, installed on one side of the specimen management cabinet 1, the pressing block 42 is magnetic, and the electromagnet 46 is suitable for magnetically repelling the pressing block 42 with magnetism after being energized. When the circuit of the ventilation system 3 is energized, the electromagnet 46 is also energized and magnetically repels the pressing block 42 to move forward to release the switch 41 to close the ventilator 34, and the connecting spring 43 is deformed. When the circuit of the ventilation system 3 is disconnected, the electromagnet 46 is also powered off and no longer magnetically repels the pressing block 42. The pressing block 42 will move backward under the action of the connecting spring 43 to press the switch 41 to start the ventilator 34, so that when the start-up time of the ventilator 34 is greater than the shutdown time, the power-off time of the electromagnet 46 is greater than the power-on time, thereby achieving the effect of energy saving and power saving.

[0038] like Figure 7 As shown, the ventilation system 3 also includes: a cleaning plate 53, connected to the ventilation pipe 31, the cleaning plate 53 is located below the ventilation net 2 33, and the cleaning plate 53 is used to passively scrape off the dust on the cleaning brush 35 during the downward movement; a dust storage frame 51, connected to the right part of the specimen management cabinet 1, the dust storage frame 51 is located below the ventilation net 2 33, and the dust cleaned from the ventilation net 2 33 when the cleaning brush 35 moves downward will be scraped off by the cleaning plate 53 and fall onto the dust storage frame 51; a cover plate 52, covering the upper part of the dust storage frame 51 The cover plate 52 is connected to the extrusion frame 44 to store dust conveniently and prevent dust from floating around. When cleaning the ventilation net 33, the pressing block 42 moves backward and drives the cover plate 52 to move backward through the extrusion frame 44 to open the dust storage frame 51, so as to automatically collect dust. After the drying and ventilation are completed, the pressing block 42 moves forward and drives the cover plate 52 to move forward through the extrusion frame 44 to close the storage frame, so that the extrusion frame 44 achieves another automatic opening and closing effect on the basis of driving the cleaning brush 35 for cleaning.

[0039] like Figure 1 , Figure 6 and Figure 7As shown, the ventilation system 3 also includes: a limit rod 61, which is slidably arranged on the specimen management cabinet 1, and the limit rod 61 is suitable for blocking between the pressing block 42 and the switch 41. When the cabinet door 11 is closed, the cabinet door 11 will squeeze the limit rod 61 to move backward, and at this time, the pressing block 42 can move backward normally to press the switch 41; a reset spring 62, which is connected between the limit rod 61 and the specimen management cabinet 1, and the reset spring 62 is located in the specimen management cabinet 1; a pressure plate 12, which is connected to the cabinet door 11, and the pressure plate 12 is connected to the limit rod 61 The return spring 62 is initially in a compressed state. When the cabinet door 11 is opened, the pressure plate 12 will release the limit rod 61. The limit rod 61 will move forward under the action of the return spring 62 to block the pressing block 42. At this time, the pressing block 42 cannot move backward and the pressing switch 41 starts the ventilator 34. This reduces the amount of active ventilation when the cabinet door 11 is opened to take and place specimens, avoids dust from being brought in during air circulation and adhering to the specimens on the specimen storage rack 2, and also saves the unnecessary active ventilation steps of the ventilator 34.

[0040] like Figure 4 and Fig. 9 As shown, the ventilation system 3 also includes: a windshield 71, which is slidably arranged inside the specimen management cabinet 1, and the windshield 71 is suitable for blocking the first end of the ventilation pipe 31, so as to further reduce the circulation of air when the cabinet door 11 is opened, and prevent dust brought in by the air circulation from adhering to the specimen; a tension spring 72, which is connected between the windshield 71 and the specimen management cabinet 1, and the tension spring 72 is used for resetting the forward-moved windshield 71; a resistance rod 73, which is connected to the windshield 71, and the resistance rod 73 contacts and cooperates with the cabinet door 11 under the action of the tension spring 72, and the cabinet door 11 in the closed state will squeeze the resistance rod 73, so that the resistance rod 73 drives the windshield 71 to move away from the first end of the ventilation pipe 31, and the tension spring 72 is deformed at this time, and when the cabinet door 11 is opened, the windshield 71 will automatically and synchronously move forward to block the first end of the ventilation pipe 31 under the action of the tension spring 72.

[0041] like Figure 2 and Fig.10 As shown, the specimen storage rack 2 includes: a frame 21, which is arranged inside the specimen management cabinet 1; a plurality of partitions 22, which are arranged in a front-to-back direction inside the frame 21 at intervals, and different specimens are separated for storage and management by utilizing the intervals between the plurality of partitions 22, so as to facilitate distinction; a subdivision label plate 221, on which the frame 21 and the partitions 22 are slidably provided with subdivision label plates 221, and on the basis of the general classification by the label pasting frame 20, labels with more specific information are pasted on the front side of the subdivision label plate 221 to further subdivide the specimens placed behind it, and the sliding subdivision label plate 221 can adjust its position without affecting the observation and the taking and placing of the specimens.

[0042] As a preferred embodiment of the present invention, the partitions 22 are slidably disposed on the frame 21, and the spacing between the plurality of partitions 22 is slidably adjusted to adjust the space that can store specimens, thereby facilitating the storage and management of specimens of different sizes.

[0043] like Fig.11 and Fig.12 As shown, the specimen storage rack 2 also includes: a slider 81 slidably arranged on the frame 21, and the sliders 81 are connected to the multiple partitions 22, and a partition 22 at the edge (rear) of the multiple partitions 22 is fixed inside the frame 21; a scissor-type telescopic frame 82, which is installed between the sliders 81, and the scissor-type telescopic frame 82 has the same number of central hinges as the sliders 81, and the central hinges of the scissor-type telescopic frame 82 are hinged to the sliders 81 one by one, so that when the position of the frontmost partition 22 is adjusted front and back, through the extension and retraction of the scissor-type telescopic frame 82, with the rearmost partition 22 as the base point, the remaining partitions 22 are moved in an equidistant arrangement.

[0044] like Fig.11 and Fig.12 As shown, the specimen storage rack 2 also includes: a connecting column 83, which is rotatably arranged on the movable end of the scissor-type telescopic frame 82; a screw rod 84, which is rotatably arranged on the frame 21, and the front end of the screw rod 84 is connected with a rotating handle. The connecting column 83 is threadedly connected to the screw rod 84, and the screw rod 84 is rotated to drive the connecting column 83 to drive the scissor-type telescopic frame 82 to extend and retract, and a self-locking function is achieved through the thread of the screw rod 84 to prevent the partition 22 from sliding randomly, thereby improving the stability when storing and managing specimens.

[0045] like Figure 1 , Figure 2 and Figure 4 As shown, the ventilation system 3 has two ventilation systems 3, which are opposite to each other up and down. The first end of the ventilation pipe 31 in the upper ventilation system 3 faces upward, and the first end of the ventilation pipe 31 in the lower ventilation system 3 faces downward. Cold air is heavier and will naturally sink, while hot air is lighter and will rise. Therefore, hot air can be discharged through the upper ventilation system 3 in summer, and cold air can be discharged through the lower ventilation system 3 in winter.

[0046] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. They only express the preferred implementation modes of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention.

[0047] It should be pointed out that, for ordinary technicians in this field, several modifications, increases and decreases in quantity, improvements and substitutions can be made without departing from the concept of the present invention. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.
