Description

Technical Field

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

[0002] Medical nasal aspirators, also known as nasopharyngeal swabs or nasal swabs, are common medical tools used to collect samples from the nasal cavity for microbial testing and virus screening. They play an important role in diagnosing infectious diseases, performing allergy testing, and monitoring respiratory health. Disinfection and sterilization of medical nasal aspirators is crucial for ensuring medical safety and preventing cross-infection. To effectively and efficiently disinfect and sterilize medical nasal aspirators, a suitable disinfection device is required. Existing technology generally does not perform further sterilization testing on medical nasal aspirators after disinfection. This may result in ineffective microbial sterilization during the sterilization process, posing a risk of cross-contamination when the aspirator is subsequently handled.

[0003] The existing Chinese patent document with publication number CN119101596A proposes an animal food microbial detection and sterilization device and 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. 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-mentioned problems. However, the use of a special detection head for microbial inactivation detection is relatively complicated to operate, and the cost of medical waste treatment is also high.

[0004] Therefore, the present invention proposes a medical nasal suction stick disinfection and sterilization microbial detection device and disinfection and sterilization detection method, which solves the problem that the operation of microbial inactivation detection using a special detection head in the prior art is relatively complicated and the cost of medical waste treatment is also high. A disinfection barrel designed with a lifting net bag is used to immerse the discarded medical nasal suction sticks in a mixed solution of ethanol and isopropyl alcohol to disinfect and sterilize microorganisms and bacteria, and then a fluorescent reagent is sprayed to detect whether the microorganisms and bacteria are completely inactivated. The method is simple to use and economical. Summary of the Invention

[0015] The present invention also provides a method for disinfecting and sterilizing a medical nasal suction stick, comprising the following steps:

[0016] Step 1: Discarded medical nasal suction sticks are immersed in a disinfectant solution for sterilization. A mixed solution of ethanol and isopropyl alcohol is prepared in a disinfection barrel. The specific ratio is 40% ethanol and 30% isopropyl alcohol, and the total alcohol concentration is 70%. The closed cover is opened and the used medical nasal suction stick is placed in the disinfection barrel. When the motor is started, the vortex stirring blade is driven to rotate to generate a vortex under the disinfection barrel. 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.

[0017] The second step is to spray the fluorescent detection reagent on the disinfected medical nasal suction stick for sterilization effect detection, start the motor two to drive the motor one to rotate, and the lifting circle rises under the limited cooperation of the limit bar one, gradually making the net bag structure with the disinfected medical nasal suction stick separated from the disinfectant solution, the counterweight circle and the auxiliary lifting sliding sleeve are integrated into one. At this time, the motor two stops working and the lifting circle remains stationary, and the motor one is restarted to rotate in the opposite direction, driving the rotating rod to rotate in the opposite direction. At this time, the auxiliary lifting sliding sleeve will continue to rise with the counterweight circle, making the net bag structure everted, and at the same time, the engaging seat also rotates with the rotating rod to rotate the flattening block 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 pipe through the fluorescent detection reagent injection box and is rotated and sprayed by the reagent spray head so that the fluorescent reagent solution is evenly sprayed and fully contacts the medical nasal suction stick after disinfection and sterilization. After spraying for a period of time, ensure that the medical nasal suction stick fully absorbs the detection reagent, stop injecting, and stop motor one to make the net bag structure remain stationary.

[0018] Step 3: Observe the medical nasal suction stick by turning on the illumination light inside the protective cover and turning off the indoor lights. If there is almost no or only a very small amount of green fluorescent signal in the sterilized and inactivated medical nasal suction stick, it means that there are no or very few living cells, which indicates that the disinfection effect is good and the microorganisms have been basically completely inactivated.

[0019] Step 4: Take out the disinfected and sterilized medical nasal suction stick for subsequent processing, and open the solution discharge pipe to release the treated solution in a centralized manner.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] By designing a medical nasal suction stick disinfection and sterilization barrel assembly to cooperate with a detection reagent spray assembly, the lifting ring, the counterweight ring and the net naturally fall down under the action of gravity when the medical nasal suction stick is soaked, making the net bag structure concave, which is convenient for concentrating the medical nasal suction stick for full soaking and disinfection and sterilization. The back rises with the cooperation of motor 1 and the rotating rod, which not only can separate the disinfected and sterilized medical nasal suction stick from the disinfectant solution but also flatten it, making it convenient for full contact with the fluorescent detection reagent. The fluorescent reagent is used to detect whether the microorganisms and bacteria are completely inactivated. It is easy to use and economical, and solves the problem that the operation of microbial inactivation detection using a special detection head in the existing technology is relatively complicated and the cost of medical waste treatment is also high.

All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For example 1, please refer to 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 provided above the medical nasal suction stick microorganism disinfection and sterilization device housing (1), a medical nasal suction stick disinfection and sterilization barrel assembly (3) is provided inside the medical nasal suction stick microorganism disinfection and sterilization device housing (1), a detection reagent spraying assembly (2) is provided above the sealing cover (11), and the medical nasal suction stick disinfection and sterilization barrel assembly (3) is provided. The invention comprises a sterilization barrel (31), wherein a rotating rod (32) is provided in the middle of the sterilization barrel (31), a threaded rod (34) is provided on one side of the sterilization barrel (31), a lifting ring (36) is provided on the outside of the rotating rod (32), a counterweight ring (37) is provided on the inside of the lifting ring (36), a solution discharge pipe (311) is fixedly installed on the bottom of the inner wall of the sterilization barrel (31), a sealing limit ring (313) is fixedly installed above the inner surface of the sterilization barrel (31), and the sterilization barrel (31) is provided with a plurality of sealing rings. A limit strip (312) is fixedly installed on the inner surface of the sterilization barrel (31), the rotating rod (32) is rotatably installed at the bottom center of the sterilization barrel (31), a motor (33) for driving the rotating rod (32) to rotate is fixedly installed at the center of the bottom lower surface of the sterilization barrel (31), a vortex stirring blade (325) is fixedly installed below the outer surface of the rotating rod (32), the threaded rod (34) is rotatably installed on one side of the bottom of the sterilization barrel (31), and the bottom lower surface of the sterilization barrel (31) is fixedly installed. 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 limiting slide groove adapted to the first limiting strip (312), a large fixing ring (361) is provided above the lifting ring (36), a small fixing ring (371) is provided 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 isopropyl alcohol is prepared inside the disinfection and sterilization barrel (31). The specific ratio is 40% ethanol and 30% isopropyl alcohol, 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). Open the sealing cover (11) and put the used medical nasal suction stick into the disinfection and sterilization barrel (31). The motor (33) is started to drive the vortex stirring blade (325) to rotate. A vortex can be generated 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 soaked and disinfected by the disinfectant solution. The motor (33) is started to drive the vortex stirring blade (325) to rotate. The vortex generated by the rotation can effectively roll the medical nasal suction stick into the bottom of the net bag, ensuring that every part can fully contact the disinfectant solution, improving the uniformity and thoroughness of the disinfection, and the vortex effect accelerates the contact frequency between the disinfectant solution and the surface of the nasal suction stick, shortening the disinfection time and improving 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.

[0035] 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 seat (322) is fixedly installed on the top of the rotating rod (32), a flattening bar (323) is fixedly installed on the outer surface of the snap 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 the auxiliary ascending sleeve (39), the side wall of the auxiliary ascending sleeve (39) is symmetrically fixedly installed with the limit strip 2 (391) adapted to the limit strip 1 (312), the lower part of the auxiliary ascending sleeve (39) is fixedly installed with the magnetic ring 2 (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 magnetic ring 1 (373) having a different magnetic pole from the magnetic ring 2 (392);In this embodiment, the counterweight ring (37) naturally falls under the action of gravity when the medical nasal suction stick is soaked and is supported and limited by the limit support seat (324), so that the net bag structure is concave, which is convenient for concentrating the medical nasal suction stick. After the medical nasal suction stick is soaked in the disinfectant solution for a period of time under the action of the vortex, the threaded rod (34) stops working to stop the rotating rod (32) from rotating, and the motor 2 (35) is started to work to drive the motor 1 (33) to rotate, and the lifting ring (36) is limited in the limit bar 1 (312). The net bag structure gradually moves upward 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 main function of the baffle (372) is to block 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. 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 rising 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 rotate in the reverse direction, driving the rotating rod (32) to rotate in the reverse direction. At this time, the auxiliary rising sleeve (39) is held in the spiral rising slideway (321) and the limit The second strip (391) cooperates with the first limit strip (312) to limit the position, and the auxiliary rising sleeve (39) will continue to rise with the counterweight ring (37). The second limit strip (391) will rise to the sealing limit 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.

[0036] For example three, please refer to Figures 1 to 10On the basis of the second embodiment, in order to make the fluorescent detection reagent be sprayed evenly, the present embodiment further proposes that the detection reagent spraying assembly (2) includes a fluorescent detection reagent injection box (21) fixedly mounted above the closed cover (11), an injection tube (211) is fixedly mounted on the top of the fluorescent detection reagent injection box (21), a protective cover (22) is fixedly mounted on the outer side of the lower surface of the fluorescent detection reagent injection box (21), an irradiation lamp (23) is fixedly mounted on the inner side of the lower surface of the fluorescent detection reagent injection box (21), a reagent input tube (24) is fixedly mounted at the center of the bottom inner wall of the fluorescent detection reagent injection box (21), a reagent spraying head (25) is rotatably mounted at the bottom of the reagent input tube (24), and an elastic clamping joint (26) adapted to the clamping seat (322) is fixedly mounted below the reagent spraying head (25); in the present embodiment, when the rotating rod (32) rotates to make the auxiliary rising 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 closing cover (11) is closed, the reagent spray head (25) is engaged with the engagement seat (322) through the elastic card 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 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. At this time, the irradiation lamp (23) inside the protective cover (22) is turned on and the indoor light is turned off. Because SYTO 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 that has been disinfected and inactivated, 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.

[0037] For example 4, please refer to Figures 1 to 10On the basis of Example 3, this 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 isopropyl alcohol in the disinfection and sterilization barrel (31), the specific ratio being 40% ethanol and 30% isopropyl alcohol, and the disinfectant solution having 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 vortex stirring blade (325) by the motor 1 (33) to rotate to generate a vortex below 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, 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 rising 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 rotate in the opposite direction, driving 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), making the net bag structure turn outward, and at the same time, the locking seat (32) is closed. 2) The flattening bar (323) rotates along 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 motor 1 (33) to keep the net bag structure stationary; step three, 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 four, take out the disinfected and sterilized medical nasal suction stick for subsequent processing, open the solution discharge pipe (311) to release the treated solution in a centralized manner.

[0038] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

A method for detecting the disinfection and sterilization of a medical nasal suction stick, implemented by the medical nasal suction stick disinfection and sterilization microbial detection device according to any one of claims 1 to 6, 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 isopropyl alcohol in a disinfectant barrel (31). The specific ratio is 40% ethanol and 30% isopropyl alcohol. 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 disinfectant barrel (31). Start the motor 1 (33) to drive the vortex stirring blade (325) to rotate, which can generate a vortex under the disinfectant 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. 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, and the lifting ring (36) rises under the limit cooperation of the limit bar 1 (312), gradually making the net bag structure with the disinfected and sterilized medical nasal suction stick out of the disinfectant solution, and 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, driving 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 out of the disinfection solution. 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. 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 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 (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.
