Description

Technical Field

[0001] The invention relates to a specimen collection device for infectious disease prevention and control, belonging to the technical field of sampling devices. Background Art

[0002] Specimen collection equipment for infectious disease prevention and control refers to a series of medical devices specifically used to collect various human (or animal) samples, such as blood, sputum, feces, tissues, secretions, etc., for the purpose of detecting pathogens, monitoring disease dynamics, conducting epidemiological surveys, and other infectious disease prevention and control related purposes. The design and use of these devices play a vital role in accurately diagnosing infectious diseases, tracing the source of infection, assessing the scale of the epidemic and the effectiveness of prevention and control, especially in the detection of respiratory infectious diseases. Throat swabs are sterile swabs used to collect secretions from the patient's pharynx and tonsillar crypts; the swabs are generally made of polyester fibers or synthetic fibers, with a soft head that will not damage the mucosa. The collected secretions can be used to detect a variety of respiratory pathogens such as the new coronavirus and influenza virus.

[0003] A throat swab sampling device with Chinese patent number CN214907263U is used for a collector to collect throat swabs from a collected person. The throat swab sampling device includes: a support unit, a table top and a shield. A socket and at least one through hole are provided on the table top. The bottom of the shield vertically passes through the socket and is fixed on the top of the support unit. The shield is a curved structure, and the shield is used to isolate the collector and the collected person. The collector uses both hands to collect throat swabs from the collected person through the two sides of the shield. Thereby, the throat swab sampling device of the present invention can effectively isolate the collected person from the collector, thereby preventing the collector from being infected due to the collection of throat swabs;

[0004] A throat swab sampling device with Chinese patent number CN113633319A comprises: a sampling head device for fixing and carrying a throat swab, a transfer platform for connecting the throat swab sampling device and an external component, and a sampling motion device for driving the sampling head device to move; the sampling motion device comprises a housing, a fixed platform, a turntable motor installed between the fixed platform and the transfer platform, two side vertical plates installed on the fixed platform, a rotating shaft installed between the two side vertical plates, a crossbeam installed on the rotating shaft, a tension spring installed between the fixed platform and the crossbeam, a lead screw motor installed on the fixed platform, a top wheel installed at the front end of the lead screw of the lead screw motor, and an anti-rotation device installed on the fixed platform; the present invention is used to avoid infection between medical staff and the person being collected during throat swab collection, and improve the safety of throat swab collection; it meets the requirements of automation, lightweight, rapid collection action, collection comfort and safety, etc.

[0005] When taking pharyngeal swab samples, normal patients can open their mouths wide under the instructions of medical staff to facilitate the sampling tools to reach the pharynx and tonsil area for collection. However, unconscious patients cannot actively adjust their body position or cooperate with instructions. Medical staff will be restricted when locating the sampling site, making it difficult for medical staff to smoothly place sampling tools (such as pharyngeal swabs, oral swabs, etc.) into the mouth or other sampling sites.

[0006] To this end, a specimen collection device for infectious disease prevention and control is proposed. Summary of the invention

[0007] In view of this, the present invention provides a specimen collection device for infectious disease prevention and control to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0008] The technical solution of the present invention is achieved as follows: a specimen collection device for infectious disease prevention and control, including an auxiliary collection component, a disposable isolation cover is arranged on the outside of the auxiliary collection component, the auxiliary collection component includes two flared inner plates corresponding to the upper and lower parts, the ends of the two flared inner plates close to each other are provided with groove strips, a pair of elastic connecting parts are installed between the two groove strips, the two elastic connecting parts are arranged symmetrically between the left and right, the end of the flared inner plate away from the elastic connecting part is fixedly connected to a U-shaped outer extension plate, a sampling cotton swab strip is passed through the auxiliary collection component, a limiting component is arranged at the ends of the two U-shaped outer extension plates close to each other, the limiting component includes a plurality of elastic limiting ropes fixedly connected to the ends of the two U-shaped outer extension plates close to each other, and a limiting clamping ring is fixedly connected between the plurality of elastic limiting ropes.

[0009] Further preferably, the specific number of the multiple elastic limiting ropes is four, and the limiting locking ring is located on the side away from the auxiliary collection component.

[0010] Further preferably, a side opening is provided at the right end of the position limiting and locking ring, and the sampling cotton swab is engaged with the inner side of the position limiting and locking ring through the side opening.

[0011] Further preferably, the lower end of the auxiliary collection component located on the upper side is fixedly connected to a protruding inner column, and one end of the protruding inner column close to the sampling mouth is fixedly connected to a lighting lamp block.

[0012] Further preferably, the protruding inner column and the lighting lamp block are located between two corresponding upper and lower groove strip openings, and the lighting lamp block cooperates with the sampling cotton swab strip.

[0013] Further preferably, the left and right sides of the disposable isolation outer cover are fixedly connected with stretchable side elastic surfaces, and the stretchable side elastic surfaces and the stretching paths of the two flared inner plates are adapted to each other.

[0014] Further preferably, one end of the disposable isolation cover close to the sampling mouth is fixedly connected to a rear deepened enclosure sheet, and the outer side wall of the disposable isolation cover is fixedly connected to a water-absorbing outer layer.

[0016] Further preferably, the disposable isolation outer cover and the rear deepened enclosure piece cooperate to wrap the two expanded inner panels.

[0017] Further preferably, the auxiliary collection component, the disposable isolation cover and the sampling cotton swab strip all extend into the sampling oral cavity.

[0018] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0019] 1. When the present invention collects samples from unconscious patients, medical staff need to operate the auxiliary collection component in view of the patient's lack of autonomous oral function. In the initial stage, the medical staff manually presses the auxiliary collection component to place it smoothly and completely into the patient's mouth, and then releases the pressing force. At this time, the expanded inner plate in the auxiliary collection component relies on the elastic recovery characteristics of the elastic connector. The expanded inner plate can effectively assist in opening the patient's mouth, creating favorable conditions for subsequent sampling work, so that medical staff can smoothly and accurately deliver the sampling cotton swab to the predetermined sampling site, thereby improving the convenience and feasibility of the sampling operation.

DETAILED DESCRIPTION

[0033] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] like Figure 1-Figure 7 As shown, an embodiment of the present invention provides a specimen collection device for infectious disease prevention and control, including an auxiliary collection component 2, a disposable isolation outer cover 7 is arranged on the outer side of the auxiliary collection component 2, the auxiliary collection component 2 includes two flared inner plates 3 corresponding to each other, the ends of the two flared inner plates 3 close to each other are provided with groove strips 4, a pair of elastic connecting members 5 are installed between the two groove strips 4, and the two elastic connecting members 5 are arranged symmetrically between the left and right, the end of the flared inner plate 3 away from the elastic connecting member 5 is fixedly connected to a U-shaped outer extension plate 6, a sampling cotton swab strip 18 runs through the auxiliary collection component 2, a limiting component 12 is arranged at the ends of the two U-shaped outer extension plates 6 close to each other, and the limiting component 12 includes a plurality of elastic limiting ropes 9 fixedly connected to the ends of the two U-shaped outer extension plates 6 close to each other, and a limiting clamping ring 8 is fixedly connected between the plurality of elastic limiting ropes 9.

[0037] When performing throat swab sampling on unconscious patients, medical staff need to operate the auxiliary collection component 2 in view of the patient's lack of autonomous oral function. In the initial stage, the medical staff manually presses the auxiliary collection component 2 to place it smoothly and completely into the patient's mouth, and then releases the pressing force. At this time, the expanded inner plate 3 in the auxiliary collection component 2 relies on the elastic recovery characteristics of the elastic connector 5. The expanded inner plate 3 can effectively assist in opening the patient's mouth, creating favorable conditions for subsequent sampling work, so that medical staff can smoothly and accurately deliver the sampling cotton swab strip 18 to the predetermined sampling site, thereby improving the convenience and feasibility of the sampling operation.

[0038] The specific number of the multiple elastic limit ropes 9 is four. The limit locking ring 8 is located on the side away from the auxiliary collection component 2. A side opening 13 is opened at the right end of the limit locking ring 8. The sampling cotton swab strip 18 is engaged with the inner side of the limit locking ring 8 through the side opening 13. The lower end of the auxiliary collection component 2 located on the upper side is fixedly connected with a protruding inner column 10. The end of the protruding inner column 10 close to the sampling oral cavity 1 is fixedly connected with a lighting block 11. The protruding inner column 10 and the lighting block 11 are located between the two corresponding groove strips 4 above and below, and the lighting block 11 cooperates with the sampling cotton swab strip 18.

[0039] During the sampling process, the sampling position of the sampling cotton swab strip 18 is accurately limited by the limiting clamping ring 8 in the limiting component 12 with the help of the elastic limiting rope 9 that is evenly distributed on the outside. When the sampling is completed and the sampling cotton swab strip 18 is taken out, the limiting structure can effectively prevent it from touching other irrelevant parts of the patient's oral cavity, thereby ensuring the purity and standardization of the collected samples to the greatest extent, providing a solid guarantee for subsequent testing work. In order to further optimize the visualization conditions of the sampling operation, a combined structure of a protruding inner column 10 and a lighting lamp block 11 is also designed in the auxiliary collection component 2. In the actual sampling process, medical staff can move the protruding inner column 10 as needed. The column 10 is turned on, and then the lighting block 11 immediately emits bright light, clearly illuminating the sampling area, expanding the visual range of medical staff, making the positioning of the sampling site more accurate, and effectively improving the accuracy and success rate of sampling. Finally, a plurality of buffer granular balls 17 are integrated into the interior of the disposable isolation cover 7. During the contact with the patient's oral cavity, these buffer granular balls 17 can give full play to the buffering and flexible adaptation effects, effectively reduce the hard impact on the patient's oral mucosa, and significantly improve the flexible fit between the overall equipment and the patient's oral cavity, further improving the patient's comfort during the sampling process, and at the same time, it is also conducive to ensuring the smooth progress of the sampling operation.

[0040] Example 2

[0041] like Figure 1 , Figure 3-Figure 7 As shown, in one embodiment, the left and right sides of the disposable isolation outer cover 7 are fixedly connected with stretchable side elastic surfaces 14, and the stretching paths of the stretchable side elastic surfaces 14 and the two flared inner plates 3 are adapted to each other. The end of the disposable isolation outer cover 7 close to the sampling oral cavity 1 is fixedly connected with a rear deepening enclosure sheet 19, the outer wall of the disposable isolation outer cover 7 is fixedly connected with a water-absorbing outer layer 15, and the inner side of the disposable isolation outer cover 7 is fixedly connected with a flexible inner layer 16, and the inner end of the flexible inner layer 16 is filled with a plurality of buffer granular balls 17, the disposable isolation outer cover 7 and the rear deepening enclosure sheet 19 cooperate to wrap the two flared inner plates 3, and the auxiliary collection component 2, the disposable isolation outer cover 7 and the sampling cotton swab strip 18 all extend into the sampling oral cavity 1.

[0042] The stretchable side elastic surface 14 symmetrically arranged on the left and right sides of the disposable isolation cover 7 can flexibly adapt to the opening and closing action of the expanded inner plate 3 to ensure that the two work together during the entire sampling process. When the disposable isolation cover 7 contacts the surface of the patient's mouth, the water-absorbing outer layer 15 on its outside can rely on its own good water absorption. It can timely absorb the saliva secreted by the patient's mouth, effectively prevent the sampling process from being hindered by excessive saliva accumulation, and effectively ensure that the sampling efficiency is not affected. A plurality of buffer granular balls 17 are also integrated into the disposable isolation cover 7. In the process of contacting the patient's mouth, these buffer granular balls 17 can give full play to the buffering and flexible adaptation effects, effectively reduce the hard impact on the patient's oral mucosa, and significantly improve the flexible fit between the overall equipment and the patient's mouth, further enhance the patient's comfort during the sampling process, and also help to ensure the smooth progress of the sampling operation.

[0043] When the present invention is working: when implementing the throat swab sampling operation on an unconscious patient, in view of the patient's lack of autonomous oral function, the medical staff needs to operate the auxiliary collection component 2. In the initial stage, the medical staff manually presses the auxiliary collection component 2 to place it smoothly and completely into the patient's oral cavity, and then releases the pressing force. At this time, the expanded inner plate 3 in the auxiliary collection component 2 relies on the elastic recovery characteristics of the elastic connector 5. The expanded inner plate 3 can effectively assist in opening the patient's oral cavity, creating favorable conditions for subsequent sampling work, so that the medical staff can smoothly and accurately deliver the sampling cotton swab strip 18 to the predetermined sampling site, thereby improving the convenience and feasibility of the sampling operation. At the same time, in order to enhance the protection effectiveness, in the auxiliary collection component A disposable isolation cover 7 is provided on the outside of the component 2, which effectively blocks the direct contact between the auxiliary collection component 2 and the internal environment of the patient's oral cavity, reducing the risk of cross infection. The stretchable side elastic surfaces 14 symmetrically arranged on the left and right sides of the disposable isolation cover 7 can flexibly adapt to the opening and closing actions of the expanded inner plate 3 to ensure that the two work together during the entire sampling process. When the disposable isolation cover 7 is in contact with the surface of the patient's oral cavity, the water-absorbing outer layer 15 on its outside can rely on its own good water absorption. It can timely absorb the saliva secreted by the patient's oral cavity, effectively preventing the sampling process from being hindered by excessive accumulation of saliva, and effectively ensuring that the sampling efficiency is not affected. In addition, there is a matching mechanism between the end holding part of the sampling cotton swab strip 18 and the limiting component 12, and the sampling The sampling cotton swab strip 18 can smoothly slide into the internal space of the auxiliary collection component 2 from the side opening 13 of the limiting component 12, and then go deep into the patient's oral cavity to carry out sampling operations. At the same time, during the sampling process, the limiting clamping ring 8 in the limiting component 12 uses the elastic limiting rope 9 that is evenly distributed on the outside to accurately limit the sampling position of the sampling cotton swab strip 18. When the sampling is completed and the sampling cotton swab strip 18 is taken out, the limiting structure can effectively prevent it from touching other irrelevant parts of the patient's oral cavity, thereby ensuring the purity and standardization of the collected samples to the greatest extent, providing solid protection for subsequent testing work. In order to further optimize the visualization conditions of the sampling operation, the auxiliary collection component 2 is also designed with a protruding inner column 10 and a lighting block The combination structure of 11, in the actual sampling process, the medical staff can open the protruding inner column 10 as needed, then the lighting block 11 instantly emits bright light, clearly illuminates the sampling area, expands the visual range of the medical staff, makes the positioning of the sampling site more accurate, and effectively improves the accuracy and success rate of sampling. Finally, a plurality of buffer granular balls 17 are integrated into the interior of the disposable isolation cover 7. In the process of contact with the patient's oral cavity, these buffer granular balls 17 can give full play to the buffering and flexible adaptation effects, effectively reduce the hard impact on the patient's oral mucosa, and significantly improve the flexible fit between the overall equipment and the patient's oral cavity, further improve the patient's comfort during the sampling process, and also help to ensure the smooth progress of the sampling operation.

[0044] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
