Description

Technical Field

[0001] The invention relates to the technical field of medical device sterilization, in particular to a sterilization device for filter element pipette tips. Background Art

[0002] The main function of the medical filter tip is to prevent cross contamination, protect the safety of laboratory personnel and samples, and extend the service life of the pipette; the medical filter tip body 405 can significantly reduce the spread of harmful products, such as bacteria, viruses, volatile, corrosive or viscous chemicals, etc., which are very likely to cause cross contamination during the pipetting process. The filter tip body 405 adds a filter element to the top of the tip. This filter element is made of materials such as polypropylene and has an optimized pore size, which can ensure the barrier effect and good air permeability, thereby adding an effective barrier between the pipette and these potential contaminants.

[0003] During use, filter tips may come into contact with various harmful substances such as bacteria, viruses, and microorganisms. If these substances remain on the filter tips, they may not only contaminate the sample used next time, but also pose a threat to human health. Therefore, the filter tips must be sterilized after use to ensure their sterility and avoid harm to the human body.

[0004] A Chinese patent discloses a medical cleaning and sterilization device with a publication number of CN209550113U, and the application date is 2018.10.31. The patented technology cleans and / or sterilizes medical items by combining ultrasonic cleaning and high-temperature steam sterilization. The ultrasonic decontamination is thorough and the high-temperature steam sterilization effect is good. The device has a simple structure and is easy to operate. By designing a new structure of the tray and the internal structure of the inner cylinder, the switching between the cleaning state and the sterilization state can be achieved by simply changing the position of the tray in the inner cylinder. In addition, the high-temperature steam generation system realizes steam recycling, heat source recovery, and energy saving.

[0017] The sterilizing device for filter cartridge pipette tips has a guide block located at the rightmost side of a guide groove in an initial state so that the intervals between a group of nozzles are small. In this case, the steam generator is turned on, and the high-temperature steam generated by the steam generator enters the interior of the connection box through an air outlet pipe, and then the steam evenly enters each folded hose and is then sprayed out through a group of nozzles. Since the nozzle spacing is small, the sprayed steam is concentrated and discharged to the position of the pipette tip placement mechanism, so that the temperature of the position of the pipette tip placement mechanism is rapidly increased, thereby accelerating the death rate of microorganisms and improving the sterilization efficiency. Moreover, the cylinder can be started, and the cylinder output end makes the driving block move to the left along the guide rail, driving a group of guide blocks on the front side to the left.

In this case, the steam generator is turned on, so that when the nozzle sprays steam, the steam is discharged at different positions, and the dispersed discharge of steam can make the steam form a wider distribution in the sterilization space, thereby enhancing the permeability of the steam, and the dispersed discharge helps the steam to better penetrate into the corners and gaps of the sterilized items, improving the thoroughness of the sterilization, and the dispersed discharge of steam can make the temperature and humidity in the sterilization space more uniform, and the uniform temperature and humidity distribution helps to achieve a more uniform sterilization effect, avoiding the occurrence of dead corners or over-sterilization during the sterilization process.

DETAILED DESCRIPTION

[0028] like Figure 1-3As shown, a sterilization device for filter cartridge pipette tips comprises a sterilization box 10, a sealing door 11 is installed on the front of the sterilization box 10, and a pipette tip placement mechanism 40 is arranged on the left side of the interior of the sterilization box 10; a steam sterilization mechanism 20 is arranged on the right side of the exterior of the sterilization box 10, and the steam sterilization mechanism 20 comprises a connection box 201 fixedly connected to the right side of the sterilization box 10, a steam generator 202 is fixedly installed on the inner bottom side of the connection box 201, and the output end of the steam generator 202 is fixedly connected to an outlet pipe 203, and the other end of the outlet pipe 203 passes through the right side surface of the sterilization box 10 and is located inside the sterilization box 10.

[0029] Specifically, the steam generator 202 is composed of a heater and a heated water tank, and a water injection pipe 206 is fixedly connected to the right side of the water tank, and the water injection pipe 206 runs through the inside of the connection box 201; the right side of the inside of the sterilizing box 10 is fixedly connected to an air inlet pipe 204, and the other end of the air inlet pipe 204 is fixedly connected to the water tank, and a condenser 205 is fixedly installed on the air inlet pipe 204, and a check valve 207 is respectively installed on the air outlet pipe 203, the air inlet pipe 204 and the water injection pipe 206. When in use, the air outlet pipe 203 only allows the steam rising from the inside of the water tank to be discharged through the air outlet pipe 203, and the water injection pipe 206 only allows the outside to inject water into the inside of the water tank, and the air inlet pipe 204 only allows the excess steam inside the sterilizing box 10 to enter and return to the inside of the water tank after condensation.

[0030] Furthermore, a controller 12 is fixedly installed on the front of the connection box 201, and the controller 12 is electrically connected to the steam generator 202; a humidity detector 14 is fixedly installed on the left end of the inner top side of the sterilization box 10, and a temperature detector 13 is fixedly installed on the right end of the inner top side of the sterilization box 10, and the temperature detector 13 and the humidity detector 14 are electrically connected to the controller 12 respectively.

[0031] When in use, open the sealed door 11, install the used pipette tip on the pipette tip placement mechanism 40, close the sealed door 11, introduce an external power supply by operating the controller 12 to start the steam generator 202, and the steam generator 202 generates high-temperature steam, which rises upward and is discharged to the inside of the sterilization box 10 through the outlet pipe 203. When the steam fills the inside of the sterilization box 10, the penetrating high-temperature steam can effectively sterilize the filter tip body 405 carrying bacteria and patient bacteria. In this process, the temperature and humidity inside the sterilization box 10 are fed back by the temperature detector 13 and the humidity detector 14. The temperature detector 13 can ensure that the temperature inside the sterilization box 10 reaches the predetermined sterilization temperature by accurately measuring the temperature, thereby effectively killing microorganisms and improving the sterilization effect; during the steam sterilization process, the appropriate humidity level can ensure that the steam can fully penetrate into the product, thereby achieving a better sterilization effect. The humidity detector 14 can ensure that the humidity is controlled within an appropriate range.

[0032] refer to Figure 1 , 7 8. The tip placement mechanism 40 includes a tray 402 rotatably connected to the surface of the sterilization box 10, the right side of the tray 402 is connected to a support plate 403 through a buckle, the right side surface of the support plate 403 is provided with a plurality of groups of circumferentially arranged inclined slots 404, the filter element tip body 405 is placed inside the inclined slots 404; the inclined slots 404 are designed to gradually tilt toward the middle from left to right; and positioning components are respectively arranged on the outside of the inclined slots 404.

[0033] Preferably, a motor 401 is fixedly installed on the left side of the sterilization box 10, and the output end of the motor 401 is fixedly connected to the tray 402; a central through groove 406 is opened on the left side of the support plate 403, and a group of bypass grooves 407 are opened inside the central through groove 406, and the bypass grooves 407 are connected to the corresponding inclined slots 404.

[0034] When in use, when the steam is concentratedly sprayed onto the surface of the support plate 403, part of the steam enters the bypass groove 407 through the middle groove 406, and then enters each independent inclined slot 404 to sterilize the outside of the independent filter tip body 405; and when the nozzle 303 is gradually turned over, the turned nozzle 303 will gradually face the vertically arranged and inclined filter tip body 405, so that the high-temperature steam is directly sprayed into the filter tip body 405, further increasing the sterilization effect and efficiency of the filter tip body 405; After the steam enters the filter tip body 405, it adheres to the inner wall of the filter tip body 405 to form water droplets. The water droplets inside the upper filter tip body 405 will flow down along the inner wall of the filter tip body 405, while the water droplets inside the lower filter tip body 405 will flow deep and gather into a water mass at the deepest part of the filter tip 405. When the lower filter tip body 405 rotates to the upper side, the water mass flows down along the inner wall of the filter tip body 405 to flush the impurities in the filter element, thereby achieving the effect of cleaning the inside of the filter tip body 405. At the same time, the controller 12 starts the motor 401 through an external power supply, and the output end of the motor 401 drives the tray 402 and the support plate 403 to rotate, so that the filter tip bodies 405 at different positions can be flipped to a vertical position facing the nozzle 303, so that all the filter tip bodies 405 can be effectively sterilized. At the same time, after sterilization, the tray 402 can be separated from the support plate 403 by opening the snap fasteners, so that the support plate 403 can be easily taken out.

[0035] Furthermore, the positioning assembly includes a positioning ring 409 arranged on the right side of each inclined slot 404, the positioning ring 409 is fixedly connected to the support plate 403, and the inner bottom side shape of the positioning ring 409 is adapted to the bottom shape of the filter element nozzle body 405 after the tilted placement; the top of the positioning ring 409 is slidably connected to a pull rod 411, and the pull rod 411 extends downward and penetrates the positioning ring 409, and the top of the positioning ring 409 is fixedly connected to a support spring 412, and the top of the support spring 412 is fixedly connected to the handle portion at the top of the pull rod 411, and the bottom of the pull rod 411 is fixedly connected to a pressure block 410, and the bottom of the pressure block 410 is adapted to the shape of the top of the filter element nozzle body 405 after the tilted placement.

[0036] When in use, pull rod 411 is pulled upward, which drives pressure block 410 to move upward and supports spring 412, and then filter tip body 405 is inserted into the inclined slot 404, and then pull rod 411 is released, so that support spring 412 rebounds and drives pressure block 410 to press against the surface of filter tip body 405, thereby achieving the effect of positioning filter tip body 405.

[0037] refer to Figure 1-6 An adjustment mechanism 30 is provided on the right side inside the sterilization box 10, and the adjustment mechanism 30 includes a connection box 301 fixedly connected to the right side of the sterilization box 10, and the right side of the connection box 301 is fixedly connected to the air outlet pipe 203, and a group of vertically arranged folding hoses 302 are fixedly connected to the right side of the connection box 301, and a nozzle 303 with adjustable spacing is fixedly connected to the left side of the folding hose 302.

[0038] Preferably, a flow valve 304 is installed on the foldable hose 302, and the flow valve 304 is electrically connected to the controller 12. The flow valve 304 is controlled by the controller 12 to accurately adjust the steam discharge flow of each nozzle 303, which can avoid steam waste and effectively reduce energy consumption.

[0039] Specifically, a support plate 305 is fixedly connected to the right side of the interior of the sterilization box 10, and a fixed frame 306 is fixedly connected to the left side of the top of the support plate 305. The interior of the fixed frame 306 is hollow and has openings on the left and right sides. A group of guide grooves 307 are respectively provided on the front and rear sides of the fixed frame 306, wherein the guide groove 307 in the middle position is horizontal, while the guide grooves 307 on the upper and lower sides are gradually inclined toward the middle from left to right, and the inclination angle of the guide grooves 307 on the outside is larger; a connecting block 308 is fixedly connected to the outside of the nozzle 303, and connecting rods 309 are respectively fixedly connected to the front and rear sides of the connecting block 308. The outer side of the rod 309 is rotatably connected to a guide block 316, and the connecting rod 309 in the middle position is fixedly connected to the guide block 316, and the guide block 316 is slidably connected to the corresponding guide groove 307; the upper and lower sides of the front side of the fixed frame 306 are respectively fixedly connected to guide rails 312, and the inner side of a pair of guide rails 312 is slidably connected to a driving block 315, and a vertical groove is opened on the rear side of the driving block 315, and the vertical groove is slidably connected to a group of connecting rods 309 on the front side; a cylinder 310 is arranged on the right side of the driving block 315, and the base of the cylinder 310 is fixedly connected to the inner wall of the sterilization box 10, and the output end of the cylinder 310 is fixedly connected to the driving block 315.

[0040] In the initial state, the guide block 316 is located at the rightmost side of the guide groove 307, so that the intervals between a group of nozzles 303 are small. In this case, the steam generator 202 is turned on, and the high-temperature steam generated by the steam generator 202 enters the interior of the connecting box 301 through the exhaust pipe 203, and then the steam evenly enters each folded hose 302 and is then ejected through a group of nozzles 303. Since the distance between the nozzles 303 is small, the ejected steam is concentrated and discharged to the position of the suction head placement mechanism 40, so that the temperature at the position of the suction head placement mechanism 40 rises rapidly, thereby accelerating the death rate of microorganisms and improving the sterilization efficiency. In addition, the cylinder 310 can be started. The output end of the cylinder 310 causes the driving block 315 to move to the left along the guide rail 312, and drives the front group of guide blocks 316 to the left. When the guide blocks 316 are driven to the left, the guide blocks 316 slide inside the guide groove 307, so that the nozzles 303 on the upper and lower sides move upward while moving to the left, and the nozzles 303 on the outer sides move more upward, so that a group of nozzles 303 are evenly bifurcated outward with the center as the bifurcation point, and the distance between a group of nozzles 303 is increased. In this case, the steam is turned on. When the generator 202 and thus the nozzle 303 spray steam, the steam is discharged from different positions. The dispersed discharge of steam can make the steam form a wider distribution in the sterilization space, thereby enhancing the permeability of the steam, and the dispersed discharge helps the steam to better penetrate into every corner and gap of the sterilized items, thereby improving the thoroughness of the sterilization, and the dispersed discharge of steam can make the temperature and humidity in the sterilization space more uniform. The uniform temperature and humidity distribution helps to achieve a more uniform sterilization effect and avoid dead corners or over-sterilization during the sterilization process.

[0041] Furthermore, a group of guide grooves 307 are fixedly connected to the outer side with an inclined tooth plate 313 (except the middle guide groove 307), and the inclination degree of the inclined tooth plate 313 is adapted to the inclination degree of the corresponding guide groove 307, so that the inclined tooth plate 313 is longer towards the outer side; a gear 314 is fixedly connected to the outer side of the connecting rod 309 corresponding to the position of the inclined tooth plate 313, and the gear 314 is meshed with the corresponding inclined tooth plate 313.

[0042] In the process of the output end of the cylinder 310 driving a group of nozzles 303 to fork, the nozzle 303 drives the rear connecting rod 309 to move in the same direction, driving the corresponding gear 314 to transmit along the surface of the inclined tooth plate 313, so that the connecting rod 309 and the nozzle 303 are turned outward; while the nozzle 303 sprays steam, the nozzle 303 is turned outward, so that the sprayed steam is fan-shaped, and the fan-shaped gas injection can cover a larger area, so that more filter tips can be sterilized in one injection process; and, by positioning the output end of the cylinder 310 at different positions, the nozzle 303 is positioned at different flipping angles, allowing gas to be sprayed from multiple angles and positions, ensuring that each filter tip can be evenly and fully sterilized, especially those corners and gaps that are difficult to reach, the fan-shaped gas injection helps to form a strong airflow disturbance, so as to more effectively peel off and remove microorganisms attached to the surface of the filter tip.

[0043] The working principle of the present invention is: in the initial state, the guide block 316 is located at the rightmost side of the guide groove 307, so that the interval between a group of nozzles 303 is small. In this case, the steam generator 202 is turned on, and the high-temperature steam generated by the steam generator 202 enters the inside of the connecting box 301 through the outlet pipe 203, and then the steam evenly enters each folded hose 302 and then is sprayed out through a group of nozzles 303. Since the spacing between the nozzles 303 is small, the sprayed steam is concentrated and discharged to the position of the suction head placement mechanism 40, so that the temperature at the position of the suction head placement mechanism 40 is rapidly increased, thereby accelerating the death rate of microorganisms and improving the sterilization efficiency. In addition, the cylinder 310 can be started. The output end of the cylinder 310 causes the driving block 315 to move to the left along the guide rail 312, and drives the front group of guide blocks 316 to the left. When the guide blocks 316 are driven to the left, the guide blocks 316 slide inside the guide groove 307, so that the nozzles 303 on the upper and lower sides move upward while moving to the left, and the nozzles 303 on the outer sides move more upward, so that a group of nozzles 303 are evenly bifurcated outward with the center as the bifurcation point, and the distance between a group of nozzles 303 is increased. In this case, the steam is turned on. When the generator 202 and thus the nozzle 303 spray steam, the steam is discharged from different positions. The dispersed discharge of steam can make the steam form a wider distribution in the sterilization space, thereby enhancing the permeability of the steam, and the dispersed discharge helps the steam to better penetrate into every corner and gap of the sterilized items, thereby improving the thoroughness of the sterilization, and the dispersed discharge of steam can make the temperature and humidity in the sterilization space more uniform. The uniform temperature and humidity distribution helps to achieve a more uniform sterilization effect and avoid dead corners or over-sterilization during the sterilization process.
