Description

Technical Field

[0001] This utility model relates to the field of microbial inoculation technology, and in particular to a compound self-disinfecting inoculation device with multiple inoculation heads. Background Technology

[0002] In the field of microbial inoculation, ensuring the safety and efficiency of the inoculation process is paramount. Microbial inoculation, as a fundamental operation in microbiological research and practical applications, is widely used in various industries such as medical testing, biopharmaceuticals, and food fermentation. During microbial inoculation, the sterilization of the inoculation needle is a crucial step in ensuring the safety and effectiveness of the inoculation.

[0003] Traditional inoculation devices use a single disinfection method, which is insufficient to completely kill pathogens carried on the inoculation needle. This can lead to the spread of pathogens to new samples or culture media during subsequent inoculation processes, causing cross-infection, affecting the accuracy of experimental results, and potentially threatening the health of operators. In addition, when performing continuous microbial inoculation operations, it is necessary to frequently change the inoculation tip to ensure inoculation accuracy and avoid cross-contamination. Traditional inoculation devices are cumbersome to change the inoculation tip, requiring operators to spend a lot of time and effort to complete the task, thus reducing inoculation efficiency.

[0017] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figure 1-4As shown, this embodiment provides a multi-inoculation-end compound self-disinfecting inoculation device, including: an inoculation syringe 1, an ultraviolet disinfection component 5 disposed inside the inoculation syringe 1, and an alcohol disinfection component 4 communicating with the ultraviolet disinfection component 5; the inoculation syringe 1 is hollow inside, has a preset receiving space, and is provided with a delivery tube 7 inside, the delivery tube 7 communicating with the ultraviolet disinfection component 5, the delivery tube 7 guiding and delivering the inoculation needle 10; the inoculation syringe 1 has a connecting end 2 and a needle outlet end 3 at both ends, the needle outlet end 3 being provided with a needle outlet; the alcohol disinfection component 4 is disposed inside the connecting end 2, a button 9 is provided on one side of the connecting end 2, the working surface of the button 9 is connected to a connecting rod 14, the connecting rod 14 is located inside the inoculation syringe 1, when the operator presses the button 9, the button 9 drives the connecting rod 14 to move; the side of the connecting rod 14 near the ultraviolet disinfection component 5 is connected to an extension rod 15. The extension rod 15 has a preset contact slope 1501 at one end; the ultraviolet disinfection component 5 is provided with a pushing component 6, which is used to hold the inoculation needle 10. Two adjacent inoculation needles 10 are magnetically connected by a third magnetic suction component 1001. The above connection method makes the storage and use of the inoculation needles 10 more convenient; the working surface at the top of the pushing component 6 is provided with a cutting component 21, which can contact the extension rod 15 to achieve precise pushing and cutting operations; a control switch 20 is provided on one side of the inoculation syringe 1. The control switch 20 is electrically connected to the alcohol disinfection component 4 and the ultraviolet disinfection component 5. The control switch 20 precisely controls the working state of the alcohol disinfection component 4 and the ultraviolet disinfection component 5 to ensure the safety and efficiency of the whole process; pressing the control switch 20 once turns on the alcohol disinfection component 4, and pressing it twice controls the ultraviolet disinfection component 5.

[0019] Furthermore, the transfer tube 7 is fitted with a sleeve 8, which is connected to the connecting rod 14. When the button 9 moves the connecting rod 14, the sleeve 8 can generate corresponding vibration, which accelerates the transmission speed of the inoculation needle 10 in the transfer tube 7. The transfer tube 7 is provided with a friction block 13 near the needle outlet 3. The friction block 13 can be tightly connected to the inoculation needle 10. When the inoculation needle 10 slides down the transfer tube 7 to the needle outlet 3, the friction block 13 can be tightly connected to the inoculation needle 10. Through friction with the inoculation needle 10, the friction block 13 can effectively fix the inoculation needle 10, preventing it from shaking or slipping at the needle outlet 3. This provides a stable operating basis for the operator to carry out microbial inoculation operations and improves the accuracy and reliability of the inoculation process.

[0020] like Figure 5As shown, the alcohol disinfection component 4 includes: an alcohol chamber 402, with an alcohol chamber cover 401 on the top working surface of the alcohol chamber 402. This not only facilitates the operator to replenish alcohol at any time, ensuring the continuity of disinfection work, but also effectively prevents alcohol evaporation, ensuring the concentration and disinfection effect of the alcohol; an alcohol atomizer 403 is provided at the bottom of the alcohol chamber 402, and the output end of the alcohol atomizer 403 is connected to the ultraviolet disinfection component 5. In use, the alcohol in the alcohol chamber 402 is converted into tiny droplets by the alcohol atomizer 403 and sprayed into the ultraviolet disinfection component 5, so that the alcohol can evenly cover the surface. The surface of the needle 10 enhances the comprehensiveness and effectiveness of disinfection; the alcohol atomizer 403 is existing technology and will not be described in detail here; the outer wall of the alcohol chamber 402 is provided with a stop block 17 and a first return spring 16 in sequence along its axial direction. The stop block 17 can contact the button 9, and the stop block 17 can contact the working surface of the button 9 to prevent the button 9 from damaging the outer wall of the alcohol chamber 402 due to excessive pressing pressure, thereby affecting the disinfection effect; the extension end of the first return spring 16 is connected to the connecting rod 14; the first return spring 16 undergoes elastic deformation after being squeezed, and when the button 9 is released... The first return spring 16 drives the connecting rod 14 and the extension rod 15 to return to their original positions, preparing for the next operation. The ultraviolet disinfection component 5 includes an ultraviolet chamber 501 with an opening on one side. The opening is slidably connected to the extension rod 15, and a sealing ring is provided at the connection between the opening and the extension rod 15 to effectively isolate the ultraviolet chamber 501 from the inside of the inoculation syringe 1. The inner wall of the ultraviolet chamber 501 is provided with a first magnetic suction member 503, which is magnetically connected to the pushing component 6 to accurately position and fix the pushing component 6, ensuring the position of the inoculation needle within the ultraviolet chamber 501. The system is stable, creating favorable conditions for ultraviolet disinfection. The inner wall of the ultraviolet chamber 501 is equipped with ultraviolet lamps 502 arranged in a circular array, ensuring that ultraviolet light can evenly cover all parts of the inoculation needle, greatly improving the disinfection effect. On the other side of the ultraviolet chamber 501, there is a chamber cover 504, which is hinged to the outer wall of one side of the inoculation syringe 1. This allows operators to easily open the cover 504 to remove the pusher component 6 and place a new batch of inoculation needles 10 onto it. It also facilitates cleaning and maintenance of the ultraviolet chamber 501, ensuring the safety and effectiveness of the disinfection process.

[0021] like Figure 6-8As shown, the pushing component 6 includes: a support frame 601, second magnetic suction members 602 disposed on both sides of the support frame 601, and a push plate 604 elastically connected to the support frame 601 via a thrust spring 603; the support frame 601 is provided with a limiting groove 605, and a fourth magnetic suction member is provided on the limiting groove 605; the limiting groove 605 is slidably connected to a third magnetic suction member 1001; the fourth magnetic suction member is magnetically connected to the third magnetic suction member 1001; this magnetic connection not only further fixes the position of the inoculation needle 10 in the limiting groove 605, but also allows the inoculation needle 10 to slide smoothly along the limiting groove 605, effectively preventing the inoculation needle 10 from deviating or shaking during the transmission process, ensuring that the inoculation needle can accurately reach the predetermined position; the second magnetic suction member 602 is magnetically connected to the first magnetic suction member 503, and the push plate 604 is connected to the inoculation needle. The pusher 6 is precisely positioned within the UV chamber 501, ensuring its positional stability during UV disinfection and allowing for uniform and effective UV disinfection of the inoculation needle 10. The pusher plate 604, under the action of the push spring 603, pushes the inoculation needle 10 to a preset position, ensuring the continuity and stability of the inoculation needle 10 during transport. The support frame 601 has a first opening 606 and a second opening 607 at both ends. The first opening 606 is adapted to the working size of the cutting component 21, allowing it to pass smoothly through the first opening 606 when the cutting component 21 moves under the action of the extension rod 15, thus achieving precise pushing and cutting of the inoculation needle 10. The second opening 607 is adapted to the working size of the inoculation needle 10, ensuring that the inoculation needle 10 can smoothly pass through the support frame 601 and enter the transport tube 7.

[0022] like Figure 7-8As shown, the cutting component 21 includes: a column 2101, side plates 2103 disposed on both sides of the column 2101, and a second return spring 2105 connected to the side plates 2103; the column 2101 has a connector 2102 and a cutting head 2106 at both ends, and the connector 2102 has a preset inclination arc, which can contact the contact inclined surface 1501; when the operator presses the button 9, the extension rod 15 moves under the drive of the connecting rod 14, and the inclination of the connector 2102... The inclined arc interacts with the contact inclined surface 1501, thereby driving the connector 2102 to move vertically, which in turn drives the column 2101 and the cutting head 2106 to move; the cutting head 2106 penetrates the first opening 606 and can push the third magnetic suction member 1001, thereby realizing the cutting and separation of the inoculation needle 10, allowing it to enter the transfer tube 7; a limiting rod 2104 is provided through the side plate 2103, and the limiting rod 2104 is fixedly connected to the top working surface of the bearing frame 601. The limiting rod 2104 restricts the movement trajectory of the side plate 2103 and the column 2101, ensuring the stability and accuracy of the cutting component 21 during movement, and further guaranteeing the positional accuracy of the cutting head 2106 for each movement, so that the cutting action can be performed repeatedly and accurately; when cutting the inoculation needle 10, the operator presses the button 9 to move the connecting rod 14, and the connecting rod 14 pushes the connecting head 2102 through the extension rod 15, and the connecting head 2102 drives the column 2101 to pass through the first opening 6. 06, and move towards the inoculation needle 10. At this time, the second return spring 2105 undergoes elastic deformation, and the cutting head 2106 on the column 2101 cuts and separates the third magnetic chuck 1001 on the inoculation needle 10 from the other third magnetic chucks 1001. The inoculation needle 10 falls into the transfer tube 7 through the second opening 607 by its weight. It should be noted that the extension rod 15 drives the column 2101 and the cutting head 2106 to move a distance greater than the distance from the cutting head 2106 to the third magnetic chuck 1001.

[0023] The inoculation syringe 1 is equipped with a lithium battery 18, which provides power to the entire device, ensuring independent operation in various usage scenarios and eliminating excessive reliance on external power sources, thus improving the device's flexibility and practicality. A display 11 is located on the working surface of the inoculation syringe 1 away from the control switch 20. The display 11 is electrically connected to the alcohol disinfection component 4 and the ultraviolet disinfection component 5, providing real-time and intuitive display of their operating status to the operator. The operator can clearly understand the operating status of the disinfection components 4 and 5, as well as important information such as the remaining power of the lithium battery 18, providing timely and accurate information. This provides a valuable basis for timely monitoring of the device's operation and making reasonable operational decisions. A charging port 12 is located below the display 11, facilitating the replenishment of power to the lithium battery 18 and ensuring continuous and stable operation of the device. For ease of gripping, a handle 19 is provided on one side of the connector 2102. The handle 19 conforms to ergonomic principles, allowing operators to easily grip it and reducing hand fatigue during prolonged operation. When the operator needs to push the cutting component 21 to perform the inoculation needle cutting operation, the handle 19 provides a stable and comfortable point of force, making the operation more precise and smooth, improving the operator's user experience, and making the device more convenient to use in practical applications.

[0024] Working principle: The operator places multiple inoculation needles 10, magnetically connected by the third magnetic chuck 1001, into the limiting grooves 605 on the support frame 601 of the pushing component 6. The inoculation needles 10 are fixed by the magnetic connection between the fourth magnetic chuck and the third magnetic chuck 1001. Then, the pushing component 6 is placed into the ultraviolet chamber 501 through the chamber cover 504, so that the second magnetic chuck 602 and the first magnetic chuck 503 are magnetically connected. Then, the chamber cover 504 is closed. Pressing the control switch 20 once activates the alcohol disinfection component 4. At this time, the alcohol in the alcohol chamber 402 enters the ultraviolet chamber 501 through the alcohol atomizer 403 to perform preliminary disinfection of the inoculation needles 10. Then, the operator presses the control switch 20 twice to activate the ultraviolet lamp 502, which irradiates and disinfects the inoculation needles 10 from all directions. When it is necessary to use the inoculation needles 10 to inoculate microorganisms, the operator presses the button 9. The button 9 moves the sleeve 8 and the extension rod 15 through the connecting rod 14. At this time, the extension rod 1... 5. The contact slope 1501 contacts the connector 2102 of the column 2101. Due to the preset inclination of the connector 2102, the column 2101 is displaced under the action of the contact slope 1501. The column 2101 drives the cutting head 2106 to pass through the first opening 606 and move towards the inoculation needle 10. At this time, the second return spring 2105 undergoes elastic deformation. The cutting head 2106 on the column 2101 cuts and separates the third magnetic suction member 1001 on the inoculation needle 10 from other third magnetic suction members 1001. The inoculation needle 10 falls into the conveying tube 7 through the second opening 607 by its weight. The inoculation needle 10 slides down the conveying tube 7 to the end near the needle outlet 3. At this time, the friction block 13 is tightly connected to the inoculation needle 10 to fix the position of the inoculation needle 10 and prevent it from shaking or slipping. At this time, the operator performs the inoculation operation on the microorganism. After the inoculation operation is completed, the operator pulls out the inoculation needle 10 and repeats the above operation to continue the next inoculation operation.

[0025] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
