Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical research technology, specifically a processing device for isolating and purifying human bacterial strains. Background Technology

[0002] Human bacteria are closely related to the occurrence and development of many diseases. Isolating and purifying human bacteria allows for a deeper understanding of the biological characteristics and pathogenic mechanisms of specific strains, providing important theoretical basis and research foundation for the diagnosis, treatment, and prevention of related diseases. For example, identifying the specific types of certain pathogenic bacteria helps in the development of more targeted antibiotics and vaccines.

[0003] Currently, the use of a laminar flow hood is indispensable in the process of isolating and purifying human bacterial strains. It can provide a sterile operating environment to prevent samples and strains from being contaminated. Before use, the laminar flow hood requires ultraviolet (UV) lamps to sterilize the operating area. It is generally turned on 30-60 minutes in advance to kill microorganisms in the working area. When personnel enter the laminar flow hood for experimental operations, the UV lamps must be turned off because ultraviolet rays are highly irritating and harmful to human skin and eyes. Even short-term exposure can cause skin burns, eye damage, etc. Long-term or high-intensity exposure may also increase the risk of diseases such as skin cancer. In addition, the ozone produced when the UV lamps are turned on is also harmful to health. Before entering, it is necessary to wait for a period of time for the ozone to decompose. It is usually more appropriate to ventilate for 10-15 minutes before entering.

[0004] However, some users may not be able to control the time properly, resulting in insufficient sterilization time for the ultraviolet lamps before use. For example, turning them on for only a few minutes is not enough to kill bacteria and viruses in the work area. Or, if the personnel do not leave the clean bench when the ultraviolet lamps are turned on, prolonged exposure to ultraviolet light can cause damage to the skin and eyes. Alternatively, if the ozone is not completely decomposed during use, it can also cause health hazards. Therefore, we propose a treatment device for the isolation and purification of human bacterial strains. Utility Model Content

[0005] The purpose of this invention is to provide a processing device for the isolation and purification of human bacterial strains. It has the advantages of safe use and good sterilization effect. It solves the problems that some users may not be able to control the time well enough, such as not turning on the ultraviolet lamp for a sufficient amount of time before use, such as turning it on for only a few minutes, which is not enough to kill bacteria and viruses in the work area, or that the personnel have not left the ultraviolet table when the ultraviolet lamp is turned on, and have been exposed to ultraviolet light for a long time, which will cause damage to the skin and eyes, or that the ozone is not completely decomposed during use, which will also cause health hazards.

[0028] Example 1

[0029] Please see Figures 1-5 As shown, this utility model provides a technical solution: a processing device for isolating and purifying human bacterial strains, comprising:

[0030] The frame 1 has a control panel 101 fixedly installed on the upper front end, an alarm 102 fixedly installed on the top of the frame 1, ultraviolet lamps 104 fixedly installed at both the front and rear ends of the inner top of the frame 1, an ozone sensor 103 fixedly installed at the rear end of the inner top of the frame 1, and a timer 105 and an infrared sensor 106 fixedly installed at the front end of the inner top of the frame 1.

[0031] The filter chamber 4 is located on the inner surface of the upper end of the frame 1. A dispersion channel 403 is provided between the top of the inner side of the frame 1 and the filter chamber 4. An air collection channel 406 is provided at the lower end of the inner side of the frame 1.

[0032] A fan 3 has an air inlet pipe 301 between its air inlet end and the air collection trough 406. A gas supply pipe 306 is provided between the exhaust end of the fan 3 and the filter chamber 4. A second solenoid valve 305 is provided at one end of the gas supply pipe 306. An exhaust pipe 304 is connected to the end of the gas supply pipe 306 near the fan 3. A ventilation pipe 302 is connected between the upper right side of the frame 1 and the filter chamber 4. A first solenoid valve 303 is provided at one end of both the ventilation pipe 302 and the exhaust pipe 304.

[0033] The output terminals of ozone sensor 103 and infrared sensor 106 are electrically connected to the input terminals of control panel 101 via wires. The output terminals of control panel 101 are electrically connected to the input terminals of fan 3, ultraviolet lamp 104, alarm 102, first solenoid valve 303 and second solenoid valve 305 via wires respectively. Timer 105 is bidirectionally electrically connected to control panel 101. Fan 3 is fixedly installed on the upper rear side of frame 1.

[0034] This technical solution: Through the settings of the control panel 101 (with a built-in microprocessor), after the user turns on the device, the ultraviolet lamp 104, timer 105, ozone sensor 103, and infrared sensor 106 operate. After the preset ultraviolet sterilization time of timer 105 is reached, the control panel 101 turns off the ultraviolet lamp 104 and receives information from the ozone sensor 103 to determine whether the ozone concentration in the workbench exceeds the standard. If it exceeds the standard, the control panel 101 turns on the fan 3 and the first electrically controlled valve 303. Then, the fan 3 can draw gas from the workbench through the air inlet pipe 301 and the air collection tank 406 and deliver it to the exhaust pipe 304, which discharges it into the externally preset ventilation system. At the same time, the ventilation pipe 302 can draw in outside gas into the filter chamber 4. After the gas is filtered, it enters the workbench through the dispersion channel 403, thereby enabling the workbench to quickly become clean and hygienic. As the ozone concentration inside the workbench decreases, once the ozone concentration detected by the ozone sensor 103 meets the standard, the control panel 101 activates the alarm 102 to remind the user to use the workbench promptly. Simultaneously, the control panel 101 closes the first solenoid valve 303 and opens the second solenoid valve 305. The fan 3 then draws gas from the workbench through the air inlet pipe 301 and the air collection tank 406, delivering it to the air delivery pipe 306, and finally into the filter chamber 4. This achieves gas recirculation, maintaining stable indoor air cleanliness, temperature, and humidity. If the user is in a hurry to use the workbench, the infrared sensor 106 transmits the detected signal to the control panel 101 after the user enters the work area. The control panel 101 then promptly disconnects the ultraviolet lamp 104 to prevent ultraviolet radiation from harming the user.

[0035] It should be noted that the ozone sensor 103, infrared sensor 106, control panel 101, fan 3, ultraviolet lamp 104, alarm 102, first solenoid valve 303, second solenoid valve 305 and timer 105 used in this device can all be purchased directly from the market. At the same time, the connection method and electrical connection relationship of each component adopt mature conventional methods in the existing technology, so they will not be described in detail here.

[0036] Example 2

[0037] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, the inner cavity of the filter chamber 4 is provided with a coarse filter 401 and an activated carbon filter 402 fixedly installed from top to bottom. The lower end of the inner side of the dispersion channel 403 and one end of the inner side of the gas collection channel 406 are respectively fixedly connected to a first barrier mesh plate 404 and a second barrier mesh plate 405.

[0038] This technical solution: By setting up the coarse filter 401 and the activated carbon filter 402, the filtration effect of the filter chamber 4 on the gas can be guaranteed. By setting up the first barrier mesh plate 404 and the second barrier mesh plate 405, foreign objects can be prevented from entering the dispersion channel 403 and the gas collection channel 406, ensuring smooth gas flow.

[0039] Example 3

[0040] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, the upper end of the frame 1 is provided with an n-shaped groove 2. Two guide rods 201 are fixedly connected to the upper end of the n-shaped groove 2. The front and rear ends of the outer surface of the guide rods 201 are movably connected to guide wheels 205 through bearings. A traction rope 206 is wound around the outer surface of the guide wheel 205. A counterweight block 204 is fixedly connected to one end of the traction rope 206, and a glass sliding door 202 is fixedly connected to the other end of the traction rope 206. A rubber block 207 that slides in the n-shaped groove 2 is fixedly connected to the upper end of the glass sliding door 202, and a handle 203 is fixedly installed on the lower end of the front of the glass sliding door 202.

[0041] This technical solution: By setting the n-shaped groove 2, and after setting the guide wheel 205 on the outer surface of the guide rod 201, with the assistance of the traction rope 206 and the cooperation of the counterweight 204 (the weight of the counterweight 204 is the same as the weight of the glass sliding door 202 and the handle 203), the physical exertion of the user to open the glass sliding door 202 upward is reduced. With the assistance of the rubber block 207 sliding in the n-shaped groove 2 (the setting of the rubber block 207 is conducive to the position limitation of the glass sliding door 202), the height position of the glass sliding door 202 can be determined at any time, and the glass sliding door 202 will not fall down automatically during use.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
