Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a constant temperature preservation device for pathogenic microorganism collection samples. Background Technology
[0002] Pathogenic microorganism samples refer to biological materials obtained from a patient's body or a suspected infection environment for the detection and analysis of pathogenic microorganisms. These samples may contain pathogens such as viruses, bacteria, fungi, and parasites, or related components such as antibodies, antigens, or nucleic acids. The purpose of collecting pathogenic microorganism samples is to confirm infection, determine the type of pathogen, monitor disease transmission, and conduct epidemiological studies. Sample collection is usually selected based on the patient's clinical symptoms, the suspected site of infection, and the requirements of laboratory testing.
[0003] Existing devices can only keep the device warm during actual use, but cannot actively cool the inside of the device, nor can they remove the condensate generated during cooling. The presence of water inside the device will cause a large number of bacteria to grow, which will then contaminate the collected samples. Therefore, we propose a constant temperature preservation device for pathogenic microorganism collection to solve the above problems. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figure 1As shown, a constant temperature preservation device for pathogenic microorganism collection includes a moving component 1, a fixing component 2 fixedly connected to the rear of the moving component 1, a placement component 3 rotatably connected to the front of the moving component 1, a placement plate 4 slidably connected to the inner cavity of the moving component 1, a constant temperature component 5 fixedly connected to the inner cavity of the moving component 1, a scraping component 6 rotatably connected to the front of the constant temperature component 5, a power component 7 fixedly connected to the inner cavity of the front of the moving component 1, and an LCD control panel 8 fixedly connected to the rear of the moving component 1.
[0025] In implementing this solution, the operator first places the fully charged power component 7 into the moving component 1, then places the collected sample on the placement plate 4, and then turns off the moving component 1. The operator then moves the moving component 1 by pulling it. When the operator needs to maintain the temperature inside the moving component 1 at 4 degrees Celsius, the operator activates the thermostat component 5 through the LCD control panel 8. The thermostat component 5 will then fill the moving component 1 with cold air. At the same time, when the thermostat component 5 generates low temperature, it will produce condensate. When the device is dragged, the scraping component 6 will scrape off the condensate to prevent the condensate from remaining for a long time and causing a large number of bacteria to grow.
[0026] The outer casing 11, scraper 66, exhaust pipe 55, and air duct 56 are all made of hard plastic, which is lightweight and resistant to disinfectant corrosion.
[0027] Specifically, in order to carry the device with you, such as Figure 1 and Figure 2 As shown, in this solution, the mobile component 1 includes a housing 11, with wheels 12 rotatably connected to the lower inner cavity of the housing 11, a pull rod 13 rotatably connected to the left and right ends of the housing 11, a placement slot 14 fixedly connected to the front end of the housing 11, a cover 17 rotatably connected to the upper end of the housing 11, a handle 15 rotatably connected to the upper inner cavity of the cover 17, and a pulley 16 fixedly connected to the outer surface of the wheels 12 located at the front.
[0028] When implementing this solution, the operator first puts the fully charged power unit 7 into the outer casing 11, then places the collected sample on the placement plate 4, then closes the cover 17, and then moves the device by pulling the lever 13.
[0029] Pull rod 13 is a telescopic rod. Pull rod 13 has a spring and fixing components inside, which can allow pull rod 13 to be freely stretched and fixed.
[0030] Specifically, in order to fix 17, such as Figure 1As shown, in this solution, the fixing component 2 includes a fixing plate 21. The front ends of the two fixing plates 21 are fixedly connected to the rear end of the outer shell 11. The upper ends of the two fixing plates 21 are fixedly connected to telescopic rods 22, and the upper ends of the two telescopic rods 22 are fixedly connected to barrier plates 23.
[0031] When this solution is implemented, when the operator closes the cover 17, the cover 17 will enter the placement slot of the outer casing 11. Then the baffle plate 23 will prevent the cover 17 from leaving the placement slot. The operator can then lift the device by the handle 15. When the operator wants to open the cover 17, he / she slides the baffle plate 23 down to open the cover 17.
[0032] Specifically, in order to maintain the device at 4 degrees Celsius, such as Figure 4 and Figure 5 As shown, in this scheme, the constant temperature component 5 includes a second outer shell 51. The lower end of the second outer shell 51 is fixedly connected to the bottom wall of the inner cavity of the first outer shell 11. A radiator 52 is fixedly connected to the inner wall of the inner cavity of the second outer shell 51. A motor 53 is fixedly connected to the rear end of the second outer shell 51. A fan 54 is fixedly connected to the output end of the motor 53 through a coupling. Three exhaust pipes 55 are fixedly connected to the right end of the second outer shell 51. The right ends of the three exhaust pipes 55 are all fixedly connected to an exhaust duct 56. The lower end of the exhaust duct 56 is fixedly connected to the bottom wall of the inner cavity of the first outer shell 11. Several holes are opened on the inner surface of the exhaust duct 56.
[0033] For further details, please refer to [link / reference]. Figure 4 The power assembly 7 includes a telescopic rod 71. The left end of the telescopic rod 71 is fixedly connected to the left side wall of the front inner cavity of the outer casing 11. The right end of the telescopic rod 71 is fixedly connected to a push plate 72. A mobile power supply 73 is slidably connected to the front inner cavity of the outer casing 11.
[0034] When implementing this solution, the operator places the power unit 7 into the outer casing 11, and the push plate 72 will push the power bank 73 forward so that the power port of the power bank 73 can be plugged in, while also preventing the power bank 73 from falling. Then, the operator starts the heat sink 52 and the motor 53 through the LCD control panel 8. The heat sink 52 starts to cool the surface of the outer casing 2 51 quickly, while the motor 53 drives the fan 54 to rotate, which carries the cold air on the surface of the outer casing 2 51 to the exhaust duct 56 through the exhaust pipe 55, so that the temperature inside the outer casing 11 is reduced and maintained at 4 degrees Celsius.
[0035] The device circulates air internally and does not require contact with external air to form a circulation.
[0036] The power bank 73 supplies power to the heat sink 52 so that the heat sink 52 can be used;
[0037] The model number of the radiator 52 is: Huilide 35W-JM.
[0038] Specifically, in order to scrape off the condensation produced during cooling, such as Figure 5 and Figure 7 As shown, in this scheme, the scraping component 6 includes a shaft 62, the outer surface of which is rotatably connected to the left hole of the second outer shell 51, a pulley 61 is fixedly connected to the left end of the shaft 62, a belt 63 is wound around the outer surface of the pulley 61 and the outer surface of the pulley 16, a guide rod 64 is fixedly connected to the left and right walls of the inner cavity of the second outer shell 51, a reciprocating screw 65 is fixedly connected to the right end of the shaft 62, and a scraper 66 is slidably connected to the outer surface of the reciprocating screw 65 and the outer surface of the guide rod 64.
[0039] When this solution is implemented, while the operator pulls the device, the pulley 16 will drive the belt 63 and the shaft 62 to rotate, which in turn drives the reciprocating screw 65 to rotate, causing the scraper 66 to scrape back and forth on the guide rod 64.
[0040] Specifically, in order to house the power bank 73, such as Figure 2 and Figure 6 As shown, in this solution, the placement component 3 includes a second cover 31. The left end of the second cover 31 is rotatably connected to the front end of the first outer shell 11. A second fixing plate 32 is fixedly connected to the front end of the first outer shell 11. A second pull rod 33 is slidably connected to the inner cavity of the second fixing plate 32. A spring 34 is fixedly connected to the lower end of the second fixing plate 32. The lower end of the spring 34 is fixedly connected to the second pull rod 33.
[0041] When implementing this solution, the operator pulls lever 2 33 upwards, causing spring 34 to contract and lever 2 33 to move away from cover 2 31. This allows cover 2 31 to be opened and the power bank 73 to be inserted. After the operator pulls lever 2 33 again, the operator closes cover 2 31 and then releases the lever. Spring 34 then stretches, pulling lever 2 33 back into cover 2 31, thus achieving a fixing effect.
[0042] In summary, the implementation process of this utility model is as follows:
[0043] The operator first pulls lever 2 33 upwards, causing spring 34 to contract and lever 2 33 to move away from cover 2 31. This allows cover 2 31 to be opened and the fully charged power bank 73 to be placed inside. After the operator pulls lever 2 33 again, cover 2 31 is closed. Then, the operator releases the lever, causing spring 34 to stretch and pull lever 2 33 back into cover 2 31, thus achieving a fixing effect. Next, the placement plate 4 is placed into outer casing 1 11, and then cover 1 1 1 is closed. By pulling the placement slot 14, the device can be moved.
[0044] When the operator closes the cover 17, the cover 17 will enter the placement slot of the outer casing 11. The baffle plate 23 will prevent the cover 17 from leaving the placement slot. The operator can then lift the device by the handle 15. When the operator wants to open the cover 17, he / she slides the baffle plate 23 down to open the cover 17.
[0045] When the power bank 73 is placed into the outer casing 11, the push plate 72 will push the power bank 73 forward so that the power port of the power bank 73 can be plugged in, while also preventing the power bank 73 from falling. Then, the operator will start the heat sink 52 and the motor 53 through the LCD control panel 8. The heat sink 52 will start to cool down the surface of the outer casing 2 51 quickly, while the motor 53 will drive the fan 54 to rotate, which will carry the cold air on the surface of the outer casing 2 51 to the exhaust duct 56 through the exhaust pipe 55, so that the temperature inside the outer casing 11 will be reduced and maintained at 4 degrees Celsius. When the operator pulls the device, the pulley 16 will drive the belt 63 and the shaft 62 to rotate, which will drive the reciprocating screw 65 to rotate, so that the scraper 66 will scrape back and forth on the guide rod 64 to remove the condensate on the surface of the outer casing 2 51.
[0046] It should be noted that the specific installation methods, circuit connection methods, and control methods of the motor 53, radiator 52, etc. used in this utility model are all conventional designs, and will not be described in detail in this utility model.
[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
