Abstract
Description
Technical fields:
[0001] This utility model belongs to the field of medical auxiliary device manufacturing technology, and relates to an infection-preventing medical safety sampling device, specifically a device for manually collecting solid-liquid composition test samples from the oral cavity, nasal cavity, ear, anus and genitals of the human body, which can effectively block the influence of external air or bacteria and safely and effectively avoid cross-infection of samples. Background technology:
[0002] Currently, the demand for human solid-liquid composition test samples is increasing in medical and chemical sample testing activities, especially in rural and field settings where sample collection safety is poor. For example, when manually collecting solid-liquid composition test samples from the oral cavity, nasal cavity, ear, anus, and genitals, the testing equipment used lacks safety and contamination protection. Pharyngeal swab collection refers to the process of using a medical swab to collect a small amount of secretions from the pharynx and placing it in a specially designed culture medium within a temperature-controlled device. This process can provide information about the patient's condition, including oral mucosal and pharyngeal infections. The collection site for oropharyngeal swabs should be the pharynx and tonsils. The procedure involves having the patient sit down, tilt their head back, and open their mouth wide. The swab is then used to swab across the base of the tongue to the posterior pharyngeal wall, tonsillar crypts, and lateral walls, 3-5 times repeatedly to collect mucosal cells. The swab is then gently removed, avoiding contact with the tongue, uvula, oral mucosa, and saliva. The swab is then inserted back into the sampling device or a suitable transport device. During this collection process, the person being sampled may involuntarily close their mouth or feel nauseous after being stimulated, which may prevent the sampling from being completed smoothly. In addition, when sampling with the mouth open, it is easy to come into contact with the deep oral cavity, and airway bacteria may be ejected with tension, which may contaminate the environment and infect medical staff. When sampling deep in the oral cavity, the lack of lighting makes it difficult to see the operation field clearly, resulting in a lack of operational accuracy.
[0003] Chinese utility model patent application number CN202221170861.0 discloses a novel oral swab collection device. When collecting oral cells, the operator first presses a control panel to move a control column downwards until the fixing clip is exposed. Then, the oral swab is fixed using a control knob, completing the assembly of the collection device. After assembly, a protective tube is inserted into the patient's mouth, and the control panel is pressed again to expose the oral swab for collection. After collection, releasing the control panel allows the swab to retract into the protective tube under spring action, providing immediate protection for the swab after collection. However, this technology cannot solve the problem of external bacteria easily infecting the sample when the mouth is open during sample collection.
[0004] Chinese utility model patent application number CN202122368517.4 discloses an oral support device for assisting in pharyngeal swab collection. A tooth positioning module is fixed in the user's mouth, and a hyperboloid oral support module supports the user's mouth to facilitate pharyngeal swab collection. A tongue depressor module presses down on the user's tongue root to prevent the tongue from interfering with the collection mechanism during the collection process. This device has a simple and ingenious structure, is easy to use, and ensures full exposure of the posterior pharyngeal wall of the person being sampled, assisting medical personnel or the collection machine in successfully completing the pharyngeal swab sampling. However, this device only provides support and cannot prevent external bacterial contamination of the sample.
[0005] Existing medical sample collection devices, especially those used in non-hospital settings, lack a versatile, safe, and flexible multi-functional collection tool. Therefore, this study seeks to design an infection-preventing medical safety sampling device. This device would feature an openable, closable upper and lower support section with a sealing sleeve to keep the mouth open, preventing it from closing and simultaneously preventing airway bacteria from being expelled and contaminating the air, thus infecting healthcare workers and avoiding external air contamination of the sample, which could affect the accuracy of the collection. Illumination would be included to provide clear visibility and increase operational accuracy. This device could also be used for multi-functional manual collection of solid-liquid composition test samples from the nasal cavity, ear, anus, and genitals. Summary of the Invention:
[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a safe medical sampling device to prevent infection. This device addresses the problem of sample collection efficiency being affected by the body's conditioned reflex closure when collecting solid-liquid composition test samples, the problem of airway bacteria being ejected and contaminating the air and infecting medical staff when sampling with the mouth open, the problem of external air entering and affecting the accuracy of the sample, and the problem of unclear field of vision when sampling from deep parts such as the mouth, anus, and ear.
[0007] To achieve the above-mentioned objectives, the main structure of this invention, a medical safety sampling device for preventing infection, includes: an upper support, an upper handle, an operating hole, a swab slot, a test swab, a lower support, a lower handle, a hinge, a rubber sleeve, a sampling chamber, a light, a button, and a battery. The upper support, symmetrical to the lower support, has an arc-shaped cross-section, and its front end is passivated into a smooth, rounded clamp-like structure to prevent injury to human tissue during sampling and to ensure proper sample clamping. The upper handle and upper support are integrally fitted, with their center lines forming an angle of 100-120°. A transparent operating hole is provided at the intersection of the upper handle and upper support for easy observation of the sample, allowing the operator to see the sample and its surroundings from all angles during sampling. The bottom of the outer surface of the upper handle... The device features an elastic swab slot with a non-smooth inner surface for inserting and easily removing the swab. The lower support has the same cross-sectional structure as the upper support, forming a clamp-like cavity structure. Both have an arc-shaped inner cavity that smoothly accommodates the swab. The lower handle, which works in conjunction with the upper handle, is an integral part of the lower support, with their center lines forming a 90° angle. The front ends of both the upper and lower supports are fitted with elastic rubber sleeves. These sleeves support and shield or isolate the sampling area edges, creating a stable sampling cavity and preventing surrounding tissue from converging and reducing the sampling space, thus affecting the sampling operation. The elastic rubber sleeves also further protect the surrounding tissue from scratches and limit the overall range of motion of the device. The lower support and lower handle are tightly connected to the front end of the upper handle via a rotatable hinge. When the upper handle is pressed and the lower handle is brought closer together, the front section of the upper support lifts upwards, forming a parallel sampling cavity with the lower support.
[0008] When using this utility model, after removing the outer packaging of the device, the operator holds the upper and lower handles of the device and places the front ends of the upper and lower support parts into the sampling area. Pressing the upper handle closes the lower handle, and the upper support part is raised upward to be parallel with the lower support part, thus opening up the sampling area. Under the support of the rubber sleeve, a sampling chamber is formed. The operator's other hand removes the test swab from the swab slot and passes the test swab through the operation hole into the sampling chamber to reach the sampling site for sampling.
[0009] Compared with existing technologies, this utility model features an openable and closable upper and lower support section with a closed sleeve at the front end for collecting oral solid-liquid specimens. This design opens the mouth to prevent the body from reflexively closing the mouth and affecting sampling, while also preventing the airway bacteria from being expelled and contaminating the air, infecting medical personnel, and avoiding external air contamination of the sample, thus preventing cross-infection and affecting the accuracy of sample collection. Illumination is included to provide clear visibility and increase operational accuracy. The switch is conveniently located near the handle for easy sampling. It can also be used for manual collection of solid-liquid composition test samples from the nasal cavity, ear, anus, and genitals, preventing accidental damage to surrounding tissues during sampling, effectively blocking external air or bacterial interference, and effectively avoiding cross-infection of samples. Its overall structure is reasonable, simple, safe, reliable, versatile, easy to popularize, and environmentally friendly. Attached image description:

Detailed implementation method:
[0011] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.
[0012] Example 1:
[0013] This embodiment relates to a specific structure of an infection-preventing medical safety sampling device. Its main structure includes: an upper support 1, an upper handle 2, an operating hole 3, a swab slot 4, a test swab 5, a lower support 6, a lower handle 7, a hinge 8, a rubber sleeve 9, a sampling chamber 10, a light 11, a button 12, and a battery 13. The upper support 1, symmetrical to the lower support 6, has an arc-shaped cross-section, and its front end is passivated into a smooth, rounded clamp-like structure to prevent injury to human tissue during sampling and to ensure proper sample holding. The upper handle 2 and the upper support 1 are integrally fitted, with their center lines forming an angle of 100-120°. An operating hole 3, with a transparent structure, is provided at the intersection of the upper handle 2 and the upper support 1 for easy observation of the sample, allowing the operator to see the sample and its surroundings from all angles during sampling. The outer surface of the upper handle 2... The bottom is provided with an elastic swab slot 4 with a non-smooth inner surface for inserting and inserting the test swab 5 for easy removal. The cross-sectional structure of the lower support part 6 is the same as that of the upper support part 1 and they are fitted together as a clamp-type cavity structure. Both of them have an arc-shaped inner cavity that can smoothly accommodate the test swab 5. The lower handle 7, which is used in conjunction with the upper handle 2, is an integral structure with the lower support part 6, and the center lines of the two form a 90° angle. The front end of the upper support part 1 and the lower support part 6 is fitted with an elastic rubber sleeve 9. The rubber sleeve 9 is used to support and block or isolate the edge of the sampling point to form a stable sampling cavity 10, preventing the surrounding tissues from getting close and reducing the sampling space, which would affect the sampling operation. The elastic rubber sleeve 9 also has the effect of further protecting the surrounding tissues from being scratched and limiting the range of motion of the overall device. The lower support 6 and the lower handle 7 are tightly connected to the front end of the upper handle 2 by a rotatable hinge 8. When the upper handle 2 is pressed to move closer to the lower handle 7, the front part of the upper support 1 is lifted upward to form a sampling cavity 10 with the lower support 6.
[0014] In this embodiment, after removing the outer packaging of the device, the operator holds the upper and lower handles 2 and 7 of the device and places the front ends of the upper support part 1 and the lower support part 6 into the sampling area. Pressing the upper handle 2 closes the lower handle 7, and the upper support part 1 is raised upward to be parallel to the lower support part 6, thus opening up the sampling area. Under the support of the rubber sleeve 9, a sampling cavity 10 is formed. The operator's other hand removes the test swab 5 from the swab slot 4 and passes the test swab 5 through the operation hole 3 through the sampling cavity 10 to reach the sampling site for sampling.
[0015] Example 2:
[0016] This embodiment relates to an improved infection-preventing medical safety sampling device. Its main structure is the same as in Embodiment 1, but the main structure is further enhanced with a natural light illumination system comprising an electrical information communication structure consisting of a lamp 11, a button 12, and a battery 13. The lamp 11, capable of emitting natural light, is fixedly installed on the bottom side of the front end of the arc-shaped sampling cavity 10 in the lower support 6; or the lamp 11 is fixed to either side of the two side walls of the operating hole 3 at the upper end of the upper handle 2, allowing the lamp nozzle to directly illuminate the space covered by the rubber sleeve 9, facilitating clear sampling. The light 11 has a linear focusing function, which can create a natural light atmosphere in the irradiated area, making it easier to clearly observe the color of the sample. A button 12 is provided on the outer surface of the lower part of the handle 7. A battery storage structure is embedded in the upper vertical surface of the button 12. The light 11, the button 12 and the battery 13 are connected by a embedded structure. When the upper handle 2 is pressed, the hand holding the lower handle 7 can squeeze the button 12, so that the light 11 is powered on and illuminates the sampled area, making it easier for the sampler to clearly observe the sampled area.
[0017] The lighting lamp 11 involved in this embodiment is an LED lamp or a laser lamp that can emit white light; the lighting lamp 11 is fixed to the inner side of the arc-shaped groove of the lower support part 6 and the lower handle 7 by a flexible corrugated tube, which is convenient for lighting irregular human organs.
[0018] Example 3:
[0019] The infection-preventing medical safety sampling device involved in this embodiment has the same main structure as Embodiment 1 or Embodiment 2, and is used to protect the sampling from contamination when collecting oral solid and liquid specimens. The length of the upper support part 1 is 3-6cm; the length of the lower support part 6 is 3-5cm. In this embodiment, after removing the outer packaging of the device, one hand holds the upper and lower handles 2 and 7 of the device and places the parts of the upper support part 1 and the lower support part 6 covered by the rubber sleeve 9 into the sample area of the sampled person's mouth. Press the upper handle 2 to bring the lower handle 7 together, and the upper support part 1 is raised upward to be parallel to the lower support part 6, opening the mouth. Under the cover and support of the rubber sleeve 9, a sampling cavity 10 is formed. The other hand takes the test swab 5 from the swab slot 4 and passes the test swab 5 through the operation hole 3 through the sampling cavity 10 to the sampling site for infection-preventing safety sampling.
[0020] Example 4:
[0021] This embodiment relates to an infection-preventing medical safety sampling device, whose main structure is the same as in Embodiment 1 or Embodiment 2. It is used for collecting solid-liquid samples from the nasal cavity. The upper support 1 is 1-3 cm long, the lower support 6 is 1-2 cm long, and the sampling cavity 10 has a diameter of 0.2-0.5 cm. In use, after removing the outer packaging, one hand holds the upper and lower handles 7 and inserts the upper support 1 and lower support 6 into the nasal cavity of the person being sampled. Pressing the upper handle 2 towards the lower handle 7 causes the upper support 1 to rise parallel to the lower support 6, opening the nasal cavity. With the rubber sleeve 9 providing support, the sampling cavity 10 is formed. The other hand removes the test swab 5 from the swab slot 4 and passes it through the operation hole 3 into the sampling cavity 10 to reach the sampling site for sampling. This method enables infection-preventing safe collection of solid-liquid samples from the nasal cavity, achieving the designed purpose.
