Description

Technical field:

[0001] The present invention belongs to the technical field of preparation of medical auxiliary equipment, and relates to an infection-preventing medical safety sampling device, in particular to a device for artificially 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] At present, in the medical and chemical sample inspection and testing activities, the demand for the collection of human solid-liquid composite test samples is increasing, especially in rural and outdoor places where the safety of sample collection is poor. For example, when the solid-liquid composite test samples are manually collected from the human oral cavity, nasal cavity, ear, anus and genitals, the test device used lacks safety and pollution protection. Throat swab collection refers to the process of using a medical swab to dip a small amount of secretions from the human throat and place it in a special culture, and then place it in a temperature-controlled device for culture. This process can understand the patient's condition and oral mucosal and pharyngeal infection. The collection site of the oropharyngeal swab should be the pharynx and tonsils. The step of pharyngeal swab collection is to ask the patient to sit down, tilt the head back, open the mouth, and use the swab to pass over the root of the tongue to the posterior pharyngeal wall and tonsil crypts, side walls, etc., and wipe repeatedly 3-5 times to collect mucosal cells. Gently remove the swab to avoid touching the tongue, uvula, cavity mucosa and saliva, and insert the swab 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, resulting in the sampling not being completed smoothly. In addition, when sampling with the mouth open, it is easy to contact the deep oral cavity, and airway bacteria will be tensely ejected, which can easily pollute the environment and infect medical staff. When sampling deep in the mouth, there is no light, the operating field is unclear, and the operation lacks accuracy.

[0003] The Chinese utility model patent with application number CN202221170861.0 discloses a new oral swab collection device. When collecting oral cells, the staff first needs to press the control panel to drive the control column to move downward until the fixed clip is exposed, and then fix the oral swab through the control knob to complete the assembly of the collection device. After the collection device is assembled, the protective tube is inserted into the patient's mouth, and the control panel is pressed to drive the oral swab to be exposed, and the oral cells are collected. After the collection is completed, the control panel is released, and the oral swab can be retracted into the protective tube under the drive of the spring, and the oral swab can be protected in time after the collection is completed. However, this technology cannot solve the problem that external bacteria are easy to infect the sample when the mouth is open during the sample collection process.

[0004] The Chinese utility model patent with application number CN202122368517.4 discloses an oral support device for assisting the collection of pharyngeal swabs. The tooth position positioning module is fixed in the user's oral cavity, and the user's oral cavity is supported by a hyperbolic oral support module to facilitate the collection of pharyngeal swabs. The tongue pressing module presses down the user's tongue root to avoid the tongue from interfering with the collection mechanism during the collection process. The device has a simple and ingenious structure and is easy to use. It ensures that the posterior pharyngeal wall of the person being collected is fully exposed, and assists medical staff or collection machines to successfully complete the pharyngeal swab sampling action. However, the device can only play a supporting role and cannot prevent external bacteria from contaminating the sample.

[0005] In summary, the existing medical sample collection tools, especially those used in non-hospital settings, lack safe, flexible and multifunctional collection equipment with multiple uses. Therefore, a medical safety sampling device that prevents infection is designed, which is provided with an upper and lower support part with a closed sleeve that can be opened and closed to open the mouth and prevent the mouth from closing. At the same time, it prevents airway bacteria from spraying out to pollute the air and infect medical staff, and avoids external air from polluting the sample and affecting the accuracy of the collected sample; it is provided with lighting to make the operation field clear and increase the accuracy of the operation. It can also be used for multifunctional artificial collection of solid-liquid composite test samples in the nasal cavity, ears, anus and genitals. Summary of the invention:

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and propose to design an infection-preventing medical safety sampling device to solve the problem of the collection efficiency being affected by the conditioned reflex closure of the human body when collecting solid-liquid composition test samples, to solve the problem of airway bacteria spraying out and polluting the air and infecting medical staff when sampling with the mouth open, to solve the problem of the outside air entering and affecting the accuracy of the sample, and to solve the problem of unclear field of vision when sampling deep in the mouth, such as the anus and the ear.

The operation hole enables the operator to see the sample and its surroundings in all directions when performing the sampling operation; the bottom of the outer surface of the upper handle is provided with a An elastic swab slot with a non-smooth inner surface is provided for inserting and placing the test swab and facilitating its removal; the cross-sectional structure of the lower support portion is the same as that of the upper support portion and is matched to form a clamp-type cavity structure, and the inner cavity of both of them is an arc-shaped structure to form a collection space that can smoothly accommodate the test swab; the lower handle used in conjunction with the upper handle is an integrated matching structure with the lower support portion, and the center lines of the two form a 90° angle; the front end of the upper support portion and the lower support portion are provided with an elastic rubber sleeve in the form of an outer sleeve, and the rubber sleeve is used to support and shield or isolate the edge of the sampling location to form a stable sampling cavity, so as to prevent the surrounding tissues of the sampling location from approaching and reducing the sampling space and affecting the sampling operation; the elastic rubber sleeve also has the effect of further protecting the surrounding tissues of the sampling location from being scratched and limiting the range of motion of the overall device. The connection between the lower support portion and the lower handle is tightly connected to the front end of the upper handle through a rotatable hinge. When the upper handle is pressed to move the lower handle closer, the front section of the upper support portion is lifted upward to form a sampling cavity with a parallel structure with the lower support portion.

[0008] When the present invention is in use, after removing the outer packaging of the device, the operator holds the upper and lower handles of the device and puts the front ends of the upper support part and the lower support part into the sampled area, presses the upper handle to bring the lower handles together, lifts the upper support part upward and is parallel to the lower support part, and stretches the sampled area to form a sampling cavity under the support and shielding of the rubber sleeve. The operator removes the test swab from the swab slot with the other hand, and passes the test swab from the operating hole through the sampling cavity to the sampling area to perform sampling.
