Description

Technical Field

[0001] The invention belongs to the technical field of microbial sterilization, and specifically relates to a medical nasal suction stick disinfection and sterilization microbial detection device and a disinfection and sterilization detection method. Background Art

[0002] Medical nasal suction sticks, also known as nasopharyngeal swabs or nasal swabs, are a common medical tool, mainly used to collect samples from the nasal cavity for microbial testing, virus screening, etc. They play an important role in diagnosing infectious diseases, allergy testing, and monitoring the health of the respiratory system. The disinfection and sterilization of medical nasal suction sticks is an important part of ensuring medical safety and preventing cross-infection. In order to effectively and efficiently complete the disinfection and sterilization of medical nasal suction sticks, it is necessary to select a suitable disinfection device. The existing technology generally does not perform further sterilization testing on medical nasal suction sticks after disinfection. There may be a situation in which the microorganisms are not effectively sterilized during the sterilization process, so there is still a risk of cross-contamination when the medical nasal suction stick is further processed later.

[0003] The existing Chinese patent document with publication number CN119101596A proposes an animal food microbial detection and sterilization device and a detection method thereof. By adopting an outer cylinder and an inner cylinder structure, and driving the inner cylinder to rotate by a first motor, the uniformity and sufficiency of the mixing of the sample and the reagent are achieved, and a crushing device with a blade is provided to achieve effective crushing and grinding of the sample, and finally use a detection head for detection to solve the above problems. However, the use of a special detection head for microbial inactivation detection is more complicated to operate, and the cost of using it for medical waste treatment is also high.

[0015] The present invention also provides a method for disinfection and sterilization of a medical nasal suction stick, comprising the following steps: Step 1: Mix a disinfectant solution to immerse the discarded medical nasal suction stick for disinfection and sterilization. Mix a mixed solution of ethanol and isopropanol in a disinfection barrel. The specific ratio is 40% ethanol and 30% isopropanol. Mix a disinfectant solution with a total alcohol concentration of 70%. Open the closed cover and put the used medical nasal suction stick into the disinfection barrel. When the motor is started, the vortex stirring blade is driven to rotate to generate a vortex under the disinfection barrel, so that the medical nasal suction stick is drawn into the bottom of the net bag by the vortex and is fully immersed and disinfected by the disinfectant solution. The second step is to spray the disinfected medical nasal suction stick with the fluorescent detection reagent to detect the sterilization effect, start the second motor to drive the first motor to rotate, and the lifting circle rises under the limit cooperation of the limit strip one, gradually making the net bag structure with the disinfected medical nasal suction stick out of the disinfection solution, and the counterweight circle is integrated with the auxiliary rising sliding sleeve. At this time, the second motor stops working and the lifting circle remains stationary, and the first motor is restarted to rotate in the opposite direction, driving the rotating rod to rotate in the opposite direction. At this time, the auxiliary rising sliding sleeve will continue to rise with the counterweight circle, so that the net bag structure is turned outward, and at the same time, the engaging seat also rotates with the rotating rod to rotate the flattening baffle bar to flatten the medical nasal suction stick on the net bag. During the flattening process, the fluorescent reagent solution is injected into the fluorescent detection reagent injection box through the injection tube, and the fluorescent reagent solution enters the reagent input tube through the fluorescent detection reagent injection box and is rotated and sprayed through the reagent spray head so that the fluorescent reagent solution is evenly sprayed and fully contacts with the disinfected medical nasal suction stick. After spraying for a period of time to ensure that the medical nasal suction stick fully absorbs the detection reagent, the injection is stopped, and the motor one is stopped to keep the net bag structure stationary. Step 3: Observe by turning on the illumination lamp inside the protective cover and turning off the indoor light to observe the medical nasal suction stick. If there is almost no or only a very small amount of green fluorescent signal in the medical nasal suction stick after disinfection and inactivation, it means that there are no or few living cells, which means that the disinfection effect is good and the microorganisms have been basically completely inactivated; Step 4: Take out the disinfected and sterilized medical nasal suction stick for subsequent treatment, and open the solution discharge pipe to release the treated solution in a centralized manner.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By designing the medical nasal suction stick disinfection and sterilization barrel assembly to cooperate with the detection reagent spraying assembly, the lifting circle, the counterweight circle and the net bag naturally fall down under the action of gravity when the medical nasal suction stick is immersed, so that the net bag structure is concave, which is convenient for concentrating the medical nasal suction stick for full immersion and disinfection and sterilization. The latter rises with the cooperation of the motor 1 and the rotating rod, which can not only separate the disinfected and sterilized medical nasal suction stick from the disinfection solution but also flatten it, so that it is convenient for full contact with the fluorescent detection reagent, and detects whether the microorganisms and bacteria are completely inactivated by fluorescent reagent detection. It is easy to use and economical, and solves the problem that the operation of microorganism inactivation detection using a special detection head in the prior art is relatively complicated and the cost of medical waste treatment is also high.

[0019] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figures 1 to 10The present invention provides a technical solution: a medical nasal suction stick disinfection and sterilization microorganism detection device, comprising a medical nasal suction stick microorganism disinfection and sterilization device housing (1), a sealing cover (11) is arranged above the medical nasal suction stick microorganism disinfection and sterilization device housing (1), a medical nasal suction stick microorganism disinfection and sterilization barrel assembly (3) is arranged inside the medical nasal suction stick microorganism disinfection and sterilization device housing (1), a detection reagent spraying assembly (2) is arranged above the sealing cover (11), and the medical nasal suction stick disinfection and sterilization barrel assembly (3) The invention comprises a sterilizing barrel (31), wherein a rotating rod (32) is arranged in the middle of the sterilizing barrel (31), a threaded rod (34) is arranged on one side of the sterilizing barrel (31), a lifting ring (36) is arranged outside the rotating rod (32), a counterweight ring (37) is arranged inside the lifting ring (36), a solution discharge pipe (311) is fixedly installed at the bottom of the inner wall of the sterilizing barrel (31), a sealing limit ring (313) is fixedly installed above the inner surface of the sterilizing barrel (31), and the sterilizing barrel (31) is fixedly installed with a liquid discharge pipe (311). A limit strip (312) is fixedly mounted on the inner surface of the sterilization barrel (31); the rotating rod (32) is rotatably mounted at the bottom center of the sterilization barrel (31); a motor (33) for driving the rotating rod (32) to rotate is fixedly mounted at the center of the bottom lower surface of the sterilization barrel (31); a vortex stirring blade (325) is fixedly mounted below the outer surface of the rotating rod (32); the threaded rod (34) is rotatably mounted on one side of the bottom of the sterilization barrel (31); and the bottom lower surface of the sterilization barrel (31) is fixedly mounted on the bottom of the sterilization barrel (31). A second motor (35) for driving the threaded rod (34) to rotate is fixedly installed on one side, an inner wall of one side of the lifting ring (36) is threadedly connected to the outer surface of the first motor (33), a side wall of the lifting ring (36) is provided with a limit slide groove matched with the first limit strip (312), a large fixed ring (361) is arranged above the lifting ring (36), a small fixed ring (371) is arranged above the counterweight ring (37), and a net (38) is fixedly installed between the lifting ring (36) and the counterweight ring (37) by bolts;In this embodiment, the lifting ring (36) fixes the upper part of the bag net (38) through the large fixing ring (361), and the counterweight ring (37) fixes the lower part of the bag net (38) through the small fixing ring (371), forming a detachable net bag. The net bag design makes it easy to take out the nasal suction stick after disinfection, and also facilitates the cleaning and maintenance of the inside of the container disinfection and sterilization barrel (31). A mixed solution of ethanol and isopropanol is prepared inside the disinfection and sterilization barrel (31). The specific ratio is 40% ethanol and 30% isopropanol, and the total alcohol concentration of the mixed disinfectant solution is 70%. It has good volatility and permeability, and has a strong bactericidal effect. Note that the disinfectant solution must reach more than half of the volume of the disinfection and sterilization barrel (31). The closed cover (11) is opened, and the used medical nasal suction stick can be put into the disinfection and sterilization barrel (31). The motor (33) is started to drive the vortex stirring blade (325) to rotate, and a vortex can be generated under the disinfection and sterilization barrel (31). The medical nasal suction stick is drawn into the bottom of the net bag by the vortex and is fully immersed and disinfected by the disinfectant solution. The motor (33) is started to drive the vortex stirring blade (325) to rotate. The eddy current generated by the rotation can effectively roll the medical nasal suction stick into the bottom of the net bag, ensuring that each part can fully contact the disinfection solution, improving the uniformity and thoroughness of the disinfection, and the eddy current effect accelerates the contact frequency between the disinfection solution and the surface of the nasal suction stick, shortening the disinfection time and improving the work efficiency. The detachable net bag structure composed of the lifting ring (36), the counterweight ring (37) and the bag net (38) can isolate the nasal suction stick to prevent the nasal suction stick from directly contacting the bottom or wall of the container, reducing the risk of cross contamination, and facilitating the removal of the disinfected nasal suction stick. The entire disinfection process is carried out in a closed container, avoiding the possibility of external contamination and ensuring the disinfection effect. ;

[0021] For example 2, please refer to Figures 1 to 10On the basis of the first embodiment, in order to facilitate the removal of the sterilized medical nasal suction stick, the present embodiment further proposes that a spiral ascending slideway (321) is provided on the upper outer surface of the rotating rod (32), a snap-fit ​​seat (322) is fixedly installed on the top of the rotating rod (32), a flattening baffle (323) is fixedly installed on the outer surface of the snap-fit ​​seat (322), a limit support seat (324) is fixedly installed on the lower outer surface of the rotating rod (32), and the limit support seat (324) is arranged on the vortex stirring blade (325). ), the external thread of the spiral ascending slideway (321) is connected to an auxiliary ascending sleeve (39), the side wall of the auxiliary ascending sleeve (39) is symmetrically fixedly installed with a second limit strip (391) adapted to the first limit strip (312), the lower part of the auxiliary ascending sleeve (39) is fixedly installed with a second magnetic ring (392), the upper surface of the counterweight ring (37) is provided with a baffle (372), and the inner side of the upper surface of the counterweight ring (37) is provided with a first magnetic ring (373) having a different magnetic pole from the second magnetic ring (392);In this embodiment, the counterweight ring (37) naturally falls under the action of gravity when the medical nasal suction stick is immersed and is supported and limited by the limiting support seat (324), so that the net bag structure is concave, which is convenient for concentrating the medical nasal suction stick. When the medical nasal suction stick is immersed in the disinfectant solution for a period of time under the action of the eddy current, the threaded rod (34) stops working to stop the rotating rod (32) from rotating, the motor 2 (35) is started to work to drive the motor 1 (33) to rotate, and the lifting ring (36) cooperates with the limiting position of the limiting strip 1 (312). The net bag structure gradually moves downward with the sterilized medical nasal suction stick out of the disinfectant solution until the counterweight ring (37) moves to the bottom of the auxiliary ascending sleeve (39). At this time, the auxiliary ascending sleeve (39) passes through the baffle (372). The baffle (372) is a stainless steel sheet with a bent and deformed gap. The baffle (372) mainly serves to shield the top of the magnetic ring (373) when the medical nasal suction stick is immersed, so as to prevent the medical nasal suction stick from entering the top of the magnetic ring (373). The magnetic ring 1 (373) and the magnetic ring 2 (392) are attracted and combined, and the magnetic ring 2 (392) and the magnetic ring 1 (373) are attracted together due to their different magnetic properties, so that the counterweight ring (37) and the auxiliary ascending sleeve (39) are combined into one. At this time, the motor 2 (35) stops working and the lifting ring (36) remains stationary. The motor 1 (33) is restarted to make it rotate in the reverse direction, driving the rotating rod (32) to rotate in the reverse direction. At this time, the auxiliary ascending sleeve (39) is held in place by the spiral ascending slideway (321) and the limit stop. The second strip (391) cooperates with the first limiting strip (312) to limit the position, and the auxiliary ascending sleeve (39) will continue to rise with the counterweight ring (37). The second limiting strip (391) will rise to the sealing limiting ring (313) and be limited. At this time, the counterweight ring (37) is above the lifting ring (36), so that the net bag structure is turned outward. At the same time, the locking seat (322) also rotates with the rotating rod (32) to rotate the flattening bar (323) to flatten the medical nasal suction stick on the net bag, so as to facilitate the spraying of the fluorescent detection reagent for detection. ;

[0022] For example 3, please refer to Figures 1 to 10On the basis of the second embodiment, in order to ensure that the fluorescent detection reagent can be sprayed evenly, the present embodiment further proposes that the detection reagent spraying assembly (2) comprises a fluorescent detection reagent injection box (21) fixedly mounted above the sealing cover (11), an injection pipe (211) fixedly mounted on the top of the fluorescent detection reagent injection box (21), a protective cover (22) fixedly mounted on the outer side of the lower surface of the fluorescent detection reagent injection box (21), an irradiation lamp (23) fixedly mounted on the inner side of the lower surface of the fluorescent detection reagent injection box (21), a reagent input pipe (24) fixedly mounted at the center of the bottom inner wall of the fluorescent detection reagent injection box (21), a reagent spraying head (25) rotatably mounted at the bottom of the reagent input pipe (24), and an elastic clamping joint (26) adapted to the clamping seat (322) fixedly mounted below the reagent spraying head (25); in the present embodiment, when the rotating rod (32) rotates to cause the auxiliary lifting sleeve (39) drives the counterweight ring (37) to rise, so that the medical nasal suction stick is flattened. During the process, a fluorescent reagent solution, such as SYTOX Green and PI, is injected into the fluorescent detection reagent injection box (21) through the injection tube (211). The fluorescent reagent solution enters the reagent input tube (24) through the fluorescent detection reagent injection box (21) and is sprayed through the reagent spray head (25). When the sealing cover (11) is closed, the reagent spray head (25) is engaged with the engagement seat (322) through the elastic engagement joint (26). Therefore, the rotation of the rotating rod (32) also drives the reagent spray head (25) to rotate so that the fluorescent reagent solution is evenly sprayed and fully contacts the disinfected and sterilized medical nasal suction stick. After spraying for a period of time to ensure that the medical nasal suction stick fully absorbs the detection reagent, the injection is stopped, and the motor 1 (33) is stopped to keep the net bag structure motionless. At this time, the irradiation lamp (23) inside the protective cover (22) is turned on and the indoor light is turned off. Because SYTOX Green and PI are fully absorbed by the medical nasal suction stick, the injection is stopped and the motor 1 (33) is stopped to keep the net bag structure motionless. 9 can penetrate all cells, while PI can only enter dead cells. Therefore, living cells will appear green and dead cells will appear red. Observe the medical nasal suction stick. If there is almost no or only a very small amount of green fluorescent signal in the medical nasal suction stick after disinfection and inactivation, it means that there are no or few living cells, which means that the disinfection effect is good and the microorganisms have been basically completely inactivated. The disinfected medical nasal suction stick can be directly taken out for subsequent processing without causing the risk of cross infection.

[0023] Example 4, please refer to Figures 1 to 10On the basis of the third embodiment, the present embodiment further proposes a method for disinfecting and sterilizing a medical nasal suction stick, comprising the following steps: step 1, preparing a disinfectant solution to immerse the discarded medical nasal suction stick for disinfection and sterilization, preparing a mixed solution of ethanol and isopropanol in a disinfection and sterilization barrel (31), wherein the specific ratio is 40% ethanol and 30% isopropanol, and the disinfectant solution is mixed to have a total alcohol concentration of 70%, opening the sealing cover (11) and placing the used medical nasal suction stick into the disinfection and sterilization barrel (31), and starting the motor 1 (33) to drive the vortex stirring blade (325) to rotate to generate a vortex under the disinfection and sterilization barrel (31), so that the medical nasal suction stick is drawn into the bottom of the net bag by the vortex and is fully immersed and disinfected by the disinfectant solution; step 2, spraying the disinfected medical nasal suction stick with a fluorescent detection reagent to detect the sterilization effect, and starting the motor 2 (35) to drive the vortex stirring blade (325) to rotate. The motor 1 (33) rotates, and the lifting ring (36) rises under the cooperation of the limiting bar 1 (312), gradually making the net bag structure with the sterilized medical nasal suction stick separated from the disinfectant solution, and the counterweight ring (37) and the auxiliary lifting sleeve (39) are integrated. At this time, the motor 2 (35) stops working and the lifting ring (36) remains stationary. The motor 1 (33) is restarted to make it rotate in the opposite direction, driving the rotating rod (32) to rotate in the opposite direction. At this time, the auxiliary lifting sleeve (39) will continue to rise with the counterweight ring (37), so that the net bag structure is turned outward, and at the same time, the locking seat (32) is locked. 2) The flattening bar (323) also rotates with the rotation of the rotating rod (32) to flatten the medical nasal suction stick on the net bag. During the flattening process, the fluorescent reagent solution is injected into the fluorescent detection reagent injection box (21) through the injection tube (211). The fluorescent reagent solution enters the reagent input tube (24) through the fluorescent detection reagent injection box (21) and is rotated and sprayed through the reagent spray head (25) so that the fluorescent reagent solution is evenly sprayed and fully contacts the sterilized medical nasal suction stick. After spraying for a period of time to ensure that the medical nasal suction stick fully absorbs the detection reagent, the injection is stopped. , and stop the motor 1 (33) to keep the net bag structure stationary; step 3, observe, turn on the irradiation lamp (23) inside the protective cover (22) and turn off the indoor light to observe the medical nasal suction stick. If there is almost no or only a very small amount of green fluorescent signal in the medical nasal suction stick after disinfection and inactivation, it means that there are no or few living cells, which means that the disinfection effect is good and the microorganisms have been basically completely inactivated; step 4, take out the disinfected and sterilized medical nasal suction stick for subsequent treatment, and open the solution discharge pipe (311) to release the treated solution in a centralized manner.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

10. A method for detecting the disinfection and sterilization of a medical nasal suction stick, implemented by a device for detecting the disinfection and sterilization of microorganisms of a medical nasal suction stick according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: prepare a disinfectant solution to immerse the discarded medical nasal suction stick for disinfection and sterilization. Prepare a mixed solution of ethanol and isopropanol in a disinfection barrel (31). The specific ratio is 40% ethanol and 30% isopropanol. The disinfectant solution is mixed to have a total alcohol concentration of 70%. Open the sealing cover (11) and put the used medical nasal suction stick into the disinfection barrel (31). Start the motor 1 (33) to drive the vortex stirring blade (325) to rotate, so that a vortex is generated under the disinfection barrel (31), so that the medical nasal suction stick is sucked into the bottom of the net bag by the vortex and is fully immersed and disinfected by the disinfectant solution. Step 2, spray the disinfected medical nasal suction stick with fluorescent detection reagent to detect the sterilization effect, start the motor 2 (35) to drive the motor 1 (33) to rotate, the lifting ring (36) rises under the limit cooperation of the limit strip 1 (312), and gradually makes the net bag structure with the disinfected medical nasal suction stick out of the disinfectant solution, the counterweight ring (37) and the auxiliary rising sleeve (39) are combined into one, at this time, the motor 2 (35) stops working and the lifting ring (36) remains stationary, restart the motor 1 (33) to make it rotate in the opposite direction, drive the rotating rod (32) to rotate in the opposite direction, at this time, the auxiliary rising sleeve (39) will continue to rise with the counterweight ring (37), so that the net bag structure is outside The clamping seat (322) is turned over, and at the same time, the flattening bar (323) is rotated along with the rotating rod (32) to flatten the medical nasal suction stick on the net bag. During the flattening process, the fluorescent reagent solution is injected into the fluorescent detection reagent injection box (21) through the injection tube (211). The fluorescent reagent solution enters the reagent input tube (24) through the fluorescent detection reagent injection box (21) and is rotated and sprayed through the reagent spraying head (25) so that the fluorescent reagent solution is evenly sprayed and fully contacts the sterilized medical nasal suction stick. After spraying for a period of time to ensure that the medical nasal suction stick fully absorbs the detection reagent, the injection is stopped, and the motor 1 (33) is stopped to keep the net bag structure stationary; Step 3: Observe by turning on the illumination lamp (23) inside the protective cover (22) and turning off the indoor light to observe the medical nasal suction stick. If there is almost no or only a very small amount of green fluorescent signal in the medical nasal suction stick after the disinfection and inactivation treatment, it means that there are no or few living cells, which means that the disinfection effect is good and the microorganisms have been basically completely inactivated; Step 4: Take out the disinfected and sterilized medical nasal suction stick for subsequent treatment, and open the solution discharge pipe (311) to release the treated solution in a centralized manner.
