Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pharyngeal swab collection, in particular to a sterile pharyngeal swab collection device. BACKGROUND

[0002] A pharyngeal swab is a medical examination method for detecting pathogens by collecting pharyngeal mucosa surface cells and secretions in the throat area. It is mainly used for screening and diagnosis of viral, bacterial or fungal infections, such as the new coronavirus and influenza virus. During operation, a sterile swab is used to wipe the posterior wall of the pharynx and the tonsil area, and the sample is then sent to the laboratory for analysis.

[0003] A pharyngeal swab is a common non-invasive detection method that collects pharyngeal mucosa surface cells and secretions to detect the presence of genetic material (such as RNA / DNA) or antigens of specific pathogens.

[0004] In medical detection, disease screening and scientific research experiments, pharyngeal swab collection is an important means of obtaining biological samples. However, traditional pharyngeal collection methods have many limitations, as follows:

[0005] The operation process is prone to contamination: the current common method of collecting the pharynx relies on manual operation by medical personnel, who need to hold a sterile swab and insert it into the patient's mouth to collect pharyngeal mucosa surface cells and secretions, and then place the swab in a collection container. During this process, the hands of medical personnel inevitably come into contact with the swab, which is extremely easy to attach external bacteria, viruses and other pollutants to the surface of the swab, resulting in contamination of the collected sample and affecting the accuracy of subsequent test results. For example, in the detection of nucleic acids in pharyngeal mucosa surface cells and secretions of the new coronavirus, sample contamination may cause false negative or false positive results, delaying diagnosis and prevention opportunities.

[0006] Insufficient safety protection: In the traditional collection process, the breaking of the swab usually relies on manual operation, and the force and angle are difficult to control accurately, which can easily cause the fragments of the swab with pharyngeal mucosa surface cells and secretions to splatter, exposing medical personnel to pharyngeal mucosa surface cells and secretions containing pathogens and increasing the risk of occupational infection. At the same time, the splattered pharyngeal mucosa surface cells and secretions can also contaminate the surrounding environment, and if not handled properly, they can cause the spread of pathogens. In addition, the collection container has poor sealing, and the sample is easily in contact with the outside air during storage and transportation, leading to the growth of microorganisms or changes in sample composition, affecting the effectiveness of detection.

[0007] Low operation efficiency and complex process: Traditional collection needs to use multiple independent tools (such as swabs, collection bottles, etc.), and the operation steps are complicated. Medical staff need to frequently switch tools and adjust the operation posture, which takes a long time. Especially in large-scale sample collection, the problem of low efficiency is more prominent, which not only increases the workload of medical staff, but also prolongs the waiting time of the examinee. In addition, manual operation is difficult to accurately control the collection depth and intensity according to the oral structure of different patients, which may lead to insufficient sample amount or poor sample quality of the collected pharyngeal mucosa surface cells and secretions, affecting the reliability of the test results.

[0008] High risk of cross infection: In order to reduce costs, some medical institutions do not strictly supervise the reuse of collection tools, so that different patients may be cross-infected due to human negligence during the operation process without strictly following the aseptic operation specification. Once an infection occurs, it will have a serious negative impact on the health of patients and the reputation of medical institutions.

[0009] Therefore, the device provides a sterile collection device for pharyngeal swab. SUMMARY

[0015] Further, the sterile storage bottle body is made of transparent plastic, the center of the collection groove on the limiting piston is concentric with the center of the front end of the sterile storage bottle body, and two cutting grooves are symmetrically arranged on the sterile storage bottle body.

[0018] Further, the sterile collection swab, the collection bottle, the telescopic adjusting mechanism, the cutting mechanism, the sterile storage bottle and the flip mechanism are all disposable products.

[0019] The above-mentioned at least one technical scheme adopted by the embodiment of the application can achieve the following beneficial effects:

[0020] First, through the convenient and ingenious operation mode, the patient's pharyngeal swab part is collected and stored. During the collection and storage of the pharynx, the medical staff does not need to have any contact with the sterile collection swab. At the same time, the pharyngeal mucosa surface cells and secretions on the sterile collection swab will not splash to the medical staff due to the breakage of the sterile collection swab rod, avoiding the harm to the medical staff and environmental pollution.

[0021] Second, the device adopts a contactless patient pharyngeal swab site collection and a closed storage environment. In the current traditional pharyngeal collection process, the medical staff needs to manually take the swab, insert it into the patient's mouth for collection, and put it into the container. The whole process has the risk of hand contact with the swab, which easily introduces external bacterial contamination of the sample. Through the linkage design of the telescopic adjusting mechanism and the turnover mechanism, the device realizes contactless operation. The medical staff only needs to operate the external control component to drive the telescopic adjusting mechanism in the sterile storage bottle to push out the sterile collection swab, and then use the turnover mechanism to accurately send the swab into the collection bottle. The whole process does not directly touch the swab with the hands of the medical staff, which eliminates human pollution from the source and ensures the purity of the collected sample and the accuracy of the test results.

[0022] Third, in the traditional collection method, the pharyngeal mucosa surface cells and secretions may splash when the swab is broken due to improper force control. This not only poses a biological infection risk to medical staff, but also causes biological pollution of the environment. The cutting mechanism of the device uses precise cutting technology to smoothly cut the swab inside the sterile storage bottle. The design of the collection bottle forms a closed space, effectively preventing the pharyngeal mucosa surface cells and secretions from splashing, providing a safe operating environment for medical staff, reducing the risk of occupational exposure, and eliminating the risk of pharyngeal mucosa surface cells and secretions splashing. All components in the device that come into contact with the sample, such as the sterile collection swab, the collection bottle, and the sterile storage bottle, are designed as single-use sterile, and repeated use or human contact is avoided, fundamentally eliminating the possibility of cross-infection and meeting the high standard requirements of hospital infection control, thereby reducing the risk of cross-infection.

[0023] Fourth, the device adopts an integrated design, integrating collection of the pharynx, cutting, storage, and other links in one device. The mechanisms work closely together without the need for additional tools. Medical staff only needs simple training to quickly get started, simplifying the collection process, significantly shortening the collection time of individual samples, and improving work efficiency. For example, in the context of large-scale nucleic acid screening, the collection speed can be significantly accelerated, and the waiting time of personnel can be reduced.

[0024] The whole device adopts an ergonomic streamline design, comfortable to hold, and convenient for medical staff to operate with one hand. The operation button layout is reasonable, and no complex hand movements are required during operation, further improving the convenience of operation, and having visualization and warning functions. The collection bottle and sterile storage bottle are made of transparent material, and medical staff can directly observe the sterile collection swab sample collection situation.

DETAILED DESCRIPTION

[0039] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below in combination with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] The technical solutions provided by the embodiments of the present application will be described in detail below in combination with the drawings.

[0041] The embodiments of the present application provide a pharyngeal swab sterile collection device, which comprises a sterile collection swab 1 for collecting pharyngeal mucosa surface cells and secretions of a patient, a collection bottle 2 for storing the sterile collection swab 1 after collecting the pharynx, a telescopic adjusting mechanism 3 for limiting and telescoping the sterile collection swab 1, a cutting mechanism 4 for cutting the sterile collection swab 1, a sterile storage bottle 5 for storing the sterile collection swab 1 before collecting the pharynx to facilitate sterile collection, and an overturning mechanism 6 for overturning the sterile storage bottle 5. The overturning mechanism 6 is in screw connection with the collection bottle 2. The telescopic adjusting mechanism 3 is arranged inside the sterile storage bottle 5. The cutting mechanism 4 is arranged inside the sterile storage bottle 5. The sterile collection swab 1 is inserted on the telescopic adjusting mechanism 3. The sterile collection bottle 2 is arranged on the overturning mechanism 6.

[0042] The device is convenient and ingenious in operation mode for medical staff to take and collect and store the pharyngeal swab part of the patient. In the process of collecting the pharynx and storing, the medical staff does not need to have any contact with the sterile collection swab 1. Meanwhile, the pharyngeal mucosa surface cells and secretions on the sterile collection swab 1 will not splash to the medical staff due to the breaking of the sterile collection swab 1 rod, avoiding the harm to the medical staff and environmental pollution caused by the pharyngeal mucosa surface cells and secretions on the sterile collection swab 1.

[0043] The device adopts a contactless patient pharyngeal swab site collection and a closed storage environment: in the current traditional pharyngeal collection process, medical staff need to manually take the swab, insert it into the patient's mouth for collection, and put it into the container, with the risk of hand contact with the swab throughout the process, which can easily introduce external bacterial contamination of the sample. Through the linkage design of the telescopic adjusting mechanism 3 and the turnover mechanism 6, the device realizes contactless operation. Medical staff only need to operate the external control component to drive the telescopic adjusting mechanism 3 in the sterile storage bottle 5 to push out the sterile collection swab 1, and then use the turnover mechanism 6 to accurately send the swab into the collection bottle 2. Throughout the process, the medical staff's hands do not directly touch the swab, eliminating human contamination from the source and ensuring the purity of the collected sample and the accuracy of the test results.

[0044] The collection bottle 2 and the turnover mechanism 6 are connected by threads to form a tight sealing structure. When the sterile collection swab 1 is cut by the cutting mechanism 4, it automatically falls into the collection bottle 2. Then, the turnover mechanism 6 is removed, and the collection bottle cap 22 is screwed tightly with the bottle body to isolate the outside air and bacteria, preventing the pharyngeal mucosa surface cells and secretions from being contaminated during storage and transportation, and providing a reliable sample basis for subsequent testing.

[0045] In the traditional collection method, the pharyngeal mucosa surface cells and secretions may splash when the swab is broken due to improper force control, posing a biological infection risk to medical staff and causing environmental biological contamination. The cutting mechanism 4 of the device uses precise cutting technology to smoothly cut the swab inside the sterile storage bottle 5. The design of the collection bottle 2 forms a closed space, effectively preventing the pharyngeal mucosa surface cells and secretions from splashing, providing a safe operating environment for medical staff, reducing the risk of occupational exposure, and eliminating the risk of pharyngeal mucosa surface cells and secretions splashing. All components in the device that come into contact with the sample, such as the sterile collection swab 1, the collection bottle 2, and the sterile storage bottle 5, are designed as single-use sterile components, and repeated use or human contact is avoided through operation, fundamentally eliminating the possibility of cross-infection and meeting the high standard requirements of hospital infection control, thereby reducing the risk of cross-infection.

[0046] The device adopts an integrated design, integrating pharyngeal swab collection, cutting, storage, and other links in one device. The mechanisms work closely together without the need for additional tools. Medical staff can quickly get started after simple training, simplifying the collection process, significantly reducing the time for collecting a single sample, and improving work efficiency. For example, in a large-scale nucleic acid screening scenario, the collection speed can be significantly accelerated, and the waiting time for personnel can be reduced.

[0047] The whole device adopts an ergonomic streamline design, comfortable to hold and easy for medical staff to operate with one hand. The operation button layout is reasonable, and no complex hand movements are required during operation, further improving the convenience of operation, and having visualization and warning functions. The collection bottle 2 and the sterile storage bottle 5 are made of transparent material, and medical staff can directly observe the sample collection situation of the sterile collection swab 1.

[0048] The device can also be used for the detection process of oral saliva collection.

[0049] Based on the disinfection specifications of medical equipment, the device can be disinfected and reused after disinfection is completed.

[0050] Preferably, the collection bottle 2 includes a collection bottle body 21 and a collection bottle cap 22, the collection bottle cap 22 is in threaded connection with the collection bottle body 21, the turnover mechanism 6 is in threaded connection with the collection bottle body 21, and the collection bottle body 21 is pasted with a note label 23.

[0051] If the device is used for conventional microorganism detection, there is usually no need to store liquid in the sterile storage bottle 5, because conventional microorganism detection mainly observes the natural existence state of bacteria, fungi and other microorganisms in the pharyngeal mucosa surface cells and secretions. Adding liquid may dilute the sample concentration and change the microorganism survival environment, affecting the detection results. Only the sterile collection swab 1 after collection is cut in the bottle by the cutting mechanism 4, and the seal is maintained to prevent external pollution.

[0052] If the device is used for virus nucleic acid detection, the sterile storage bottle 5 may store virus preservation liquid. Such preservation liquid usually contains components such as guanidine salt {such as guanidine isothiocyanate} to lyse viruses, release nucleic acids, and inhibit nuclease activity to prevent nucleic acid degradation, ensure the integrity of the sample during transportation and storage, and improve the accuracy of subsequent nucleic acid extraction and detection.

[0053] If the device is used for pharyngeal mucosa surface cell and secretion biochemical indicator detection, the sterile storage bottle 5 may store buffer solution. Buffer solution can maintain the pH value of pharyngeal mucosa surface cell and secretion sample stable, prevent enzymes, proteins and other biochemical substances in the sample from inactivation or denaturation due to pH fluctuation, and ensure the authenticity of the detection indicators. For example, when detecting the hormone level of pharyngeal mucosa surface cell and secretion cortisol, buffer solution can avoid the influence of sample component change on the detection results.

[0054] The collection bottle body 21 pastes the note label 23, which facilitates medical staff to quickly record patient information, collection time, sample type and other key data, avoids sample confusion, and improves the accuracy and traceability of sample management.

[0056] The turnover cover 61 of the device is in threaded connection with the collection bottle body 21, the turnover knob 63 is rotated, the first magnetic block 64 and the second magnetic block 65 are magnetically connected to realize stable opening and closing control, when the sterile collection swab 1 is used for collecting the pharynx, the sterile collection swab needs to be sent into the collection bottle 2, the medical staff rotates the turnover knob 63, the magnetic connection ensures that the turnover action is stable and accurate, the throat mucosa surface layer cells and secretions are prevented from falling or splashing due to swab shaking, after the medical staff rotates one hundred and eighty degrees, the sterile storage bottle body 51 rotates one hundred and eighty degrees, so that the sterile collection swab 1 in the sterile storage bottle 5 is rotated to face the direction of the collection bottle 2, and after the sterile collection swab 1 is cut by the cutting mechanism 4, the head of the sterile collection swab 1 falls into the collection bottle 2 under the action of gravity, so as to store and collect the sample collected from the pharynx of the patient for subsequent detection work.

[0057] Preferably, the sterile storage bottle body 51 is made of transparent plastic, the center of the collection groove on the limiting piston 34 is concentric with the center of the front end of the sterile storage bottle body 51, two cutting grooves are symmetrically arranged on the sterile storage bottle body 51, the telescopic adjusting mechanism 3 includes an adjusting rod 31, a limiting block 32, a limiting plate 33 and a limiting piston 34, the limiting plate 33 is arranged on the inner side wall inside the sterile storage bottle body 51, the limiting plate 33 is provided with a sliding groove 35, the lower end of the limiting block 32 is slidably connected in the sliding groove 35 on the limiting plate 33, limiting magnetic blocks are arranged on the front and back sides in the sliding groove 35, the lower end of the limiting block 32 is provided with an auxiliary magnetic block for magnetically connecting with the corresponding limiting magnetic block, the limiting piston 34 is provided with a collection groove for inserting the sterile collection swab 1, the adjusting rod 31 is connected with the limiting block 32, and the adjusting rod 31 passes through the sterile storage bottle body 51 and is slidably arranged outside the sterile storage bottle body 51.

[0058] When it is necessary to collect the pharynx of the patient, the sterile collection swab 1 is first inserted into the sterile storage bottle body 51, and finally inserted into the sterile piston head 54 of the sterile piston head 53, so as to limit the sterile collection swab 1 in this way, and facilitate the subsequent collection of the pharynx. The center of the collection groove on the limiting piston 34 is concentric with the center of the front end of the sterile storage bottle body 51, and the front end is conical, which can make medical staff conveniently and accurately insert the sterile collection swab 1 into the collection groove on the limiting piston 34. The limiting piston 34 can also be moved as close as possible to the front end of the sterile storage bottle body 51 by pushing the adjusting rod 31, so as to facilitate the insertion of the sterile collection swab 1 into the limiting piston 34. Then, the adjusting rod 31 is pushed forward, which drives the limiting block 32 to slide on the limiting plate 33, and finally drives the sterile collection swab 1 on the limiting piston 34 to move out of the sterile storage bottle body 51, until the limiting block 32 moves from the rear side to the front side in the sliding groove 35 on the limiting plate 33. At this time, the sterile collection swab 1 is telescoped out of the sterile storage bottle body 51, and the telescoping length of the sterile collection swab 1 reaches the length of the collection of the pharynx of the patient. At this time, the medical staff can collect the pharyngeal mucosa and secretions of the patient through the sterile collection swab 1. After the collection of the pharynx of the patient is completed, the adjusting rod 31 is stretched back to the original position, which drives the sterile collection swab 1 to be collected into the sterile storage bottle body 51 for protection. The transparent plastic material allows medical staff to directly observe the internal condition of the sterile storage bottle body 51, so as to make the best operation. At this time, the sterile collection of the pharyngeal mucosa and secretions of the patient is completed.

[0061] Preferably, the sterile collection swab 1, the collection bottle 2, the telescopic adjusting mechanism 3, the cutting mechanism 4, the sterile storage bottle 5 and the turnover mechanism 6 are all disposable products;

[0062] The sterile collection swab 1, the collection bottle 2, the telescopic adjusting mechanism 3, the cutting mechanism 4, the sterile storage bottle 5 and the turnover mechanism 6 are all disposable, which eliminates the risk of cross infection from the source. After each use, the whole is discarded, without complicated cleaning and disinfection process, which not only saves time and labor cost, but also meets the medical safety standard, especially suitable for large-scale sample collection and high-risk pathogen detection scene, providing reliable safety protection for medical staff and patients.

[0063] The device is based on the concept of modular integration and automatic operation, and through the cooperative operation of each mechanism, the whole process of collecting the throat, storing, contactless, sterilization and high efficiency are realized, and the specific principles and steps are as follows:

[0064] 1. Preparation stage: swab pre-positioning

[0065] The medical staff rotates the adjusting rod 31 of the telescopic adjusting mechanism 3, and uses the sliding groove 35 of the limiting plate 33, the magnetic adsorption of the limiting magnetic block and the limiting block 32 auxiliary magnetic block to accurately push the limiting piston 34 to the front outlet of the sterile storage bottle 5. At this time, the collection groove on the limiting piston 34 is coaxially aligned with the center of the sterile storage bottle body 51, providing a stable interface for subsequent swab insertion.

[0066] 2. Swab loading

[0067] Insert the sterile collection swab 1 into the collection groove of the limiting piston 34. Since the collection groove is concentrically designed with the storage bottle body, the swab remains vertically stable after insertion. At the same time, the conical structure at the front end of the sterile storage bottle 5 serves as a guide to prevent the swab from shifting or bending during insertion, ensuring the integrity and cleanliness of the swab.

[0068] 3. Collecting the throat

[0069] The medical staff guides the patient to open the mouth, and adjusts the extension length of the limiting piston 34 through the adjusting rod 31 to make the swab accurately reach the sampling site in the oral cavity. The magnetic limiting system of the telescopic adjusting mechanism 3 ensures that the swab does not shake during the collection process due to the patient's oral movements, ensuring that the mucosal surface cells and secretions of the throat are sufficient and evenly attached to the swab.

[0070] 4. Swab storage

[0071] After collection is completed, the adjusting rod 31 is pushed in the opposite direction, driving the limiting piston 34 to retract along the sliding groove 35 of the limiting plate 33 to the inside of the sterile storage bottle 5. During this process, the sterile piston head 54 of the sterile storage bottle body 51 cooperates with the limiting piston 34 to keep the swab movement track stable, avoiding friction with the bottle wall to cause sample shedding or contamination.

[0072] 5. Flip positioning

[0073] Start the flip mechanism 6, rotate the flip knob 63, and use the magnetic linkage of the first magnetic block 64 and the second magnetic block 65 to drive the flip cover 61 and the connected sterile storage bottle 5 to rotate 180° synchronously. During the flipping process, the magnetic connection provides stable torque to ensure smooth rotation of the sterile storage bottle 5, so that the swab is accurately aligned with the inlet of the collection bottle 2 below.

[0074] 6. Swab cutting and transfer

[0075] The medical staff presses the pressing block 41 on both sides of the sterile storage bottle body 51 to drive the cutting plate 44 of the cutting mechanism 4 to slide along the fixed block 42. The cutting tool 45 on the cutting plate 44 is quickly closed under the elastic force of the spring 43, and the swab is accurately cut off. Since the cutting action is completed in the closed sterile storage bottle 5, and the cutting tool 45 is designed to be sharp, the splashing of the throat mucosa surface cells and secretions is effectively avoided. The cut swab falls directly into the lower collection bottle 2 under the action of gravity through the conical opening at the front end of the sterile storage bottle 5.

[0076] 7. Sample sealing

[0077] The collection bottle cap 22 is rotated counterclockwise to be separated from the collection bottle body 21 by screw threads; the collection bottle 2 loaded with the swab is taken out, and the cap is tightened to complete the sample sealing. The note label 23 on the collection bottle body 21 records the patient information synchronously, which is convenient for subsequent sample tracing and management.

[0078] Technical advantage summary

[0079] Contactless operation: The whole process is realized by mechanical transmission and magnetic control, so that the medical staff's hands do not touch the swab and the sample, and the risk of human pollution is eliminated.

[0080] Precise automation: The design of magnetic connection, sterile piston head 54, and concentric collection groove ensures accurate positioning of each step and reduces operation errors.
