Description

Technical Field

[0001] This invention relates to the field of medical protective equipment technology, and in particular to a safety protective isolation panel for oral examination and pharyngeal swab collection. Background Technology

[0002] With the spread of the COVID-19 pandemic, both diagnosis and epidemic prevention require nucleic acid testing, and the specimens for nucleic acid testing are generally throat swabs. During throat swab sampling, on the one hand, patients need to be face-to-face after removing their masks, making it very easy for medical staff to be infected during the process of collecting the swab specimen from the patient's throat; on the other hand, the droplets or aerosols carrying pathogens produced by the patient's breathing increase the infection rate of medical staff; furthermore, the collection of throat swabs is particularly irritating to the throat, and patients are likely to cough or sneeze, greatly contaminating the environment around the ward, which is very detrimental to effective control of infectious diseases and poses a potential risk of cross-infection. What seems like a simple throat swab sampling has become one of the most dangerous operations on the front lines of epidemic prevention. How to completely prevent infection for both medical staff and those being sampled, and how to reduce the psychological stress on medical staff, are important challenges we now face.

[0003] During oral examinations and treatments, healthcare workers also face the risk of infection from patients. To eliminate this risk, current methods involve creating openings in transparent panels to allow collection swabs or other long-handled oral medical instruments to pass through unimpeded. While this panel structure does block droplets or aerosols carrying pathogens from the patient's breathing to some extent, the openings still allow for airflow. This means that droplets or aerosols carrying pathogens from the patient's breathing can still enter the healthcare worker's field of vision through the openings, posing a risk of infection. In addition, some people fix or insert the collection skewer into the middle of the panel. Although this structure avoids the drawback of directly opening holes in the panel, the collection skewer is not easy to remove and needs to be moved with the entire transparent panel to allow the skewer tip to enter the pharyngeal swab culture tube. In other words, when medical staff are operating with both hands, the hand holding the pharyngeal swab culture tube is easily touched by the panel facing the patient, which undoubtedly increases the risk of infection for medical staff. If the oral long-handled medical instrument is fixed or inserted into the middle of the panel, the actual operation requires constantly rotating the direction of the panel and constantly adjusting the distance between the panel and the examinee, which undoubtedly increases the difficulty of the work for medical staff. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a safe and protective isolation panel for oral examinations and throat swab collection that is simple in structure, easy to operate, reduces the psychological pressure on medical staff, and eliminates the risk of infection for medical staff.

[0005] To achieve the above objectives, the present invention provides a safety protective isolation panel for oral examination and pharyngeal swab collection, comprising a sheet-like transparent face shield body, a pharyngeal swab collection device with a collection tag, the sheet-like transparent face shield body being placed between the face of the pharyngeal swab collector and the subject, a foldable long strip of plastic hand strap being provided on one side of the face shield body, the two ends of the hand strap being fixed to one side of the face shield body, a slide rail being provided perpendicular to the hand strap on the other side of the face shield body relative to the hand strap for the collection tag to move, the outer end of the slide rail being provided with a perforation for easy entry and exit of the collection tag, the inner end of the slide rail being located at the center of the face shield body, and sealing strips made of elastic material being provided on both sides of the inner side of the slide rail, the width of the sealing strips on both sides of the inner side of the slide rail being greater than or equal to the width of the slide rail.

[0006] The main body of the face shield is circular or square in shape, and the perforation is circular, square, or semi-circular; the elastic material of the sealing strip is sponge, rubber, or silicone.

[0007] The oral examination and pharyngeal swab collection safety protection isolation panel of this invention has a simple structure and is easy to operate. The transparent face shield separates the collector from the subject, thus preventing the patient's droplet spray. Because the transparent face shield has a sliding channel that is sealed after being filled with an elastic sealing strip, it fundamentally eliminates the risk of the collector being infected by droplets or aerosols carrying pathogens generated by the patient's breathing that could easily enter the collector's face due to direct openings in the transparent face shield. It also avoids the risk of the collector being infected by the operator's hand holding the pharyngeal swab culture tube being touched by the face shield facing the patient when the collection tether is fixed or inserted into the middle of the face shield. At the same time, it also eliminates the problem of increasing the difficulty of the work by fixing or inserting long-handled oral medical examination instruments into the middle of the face shield.

[0008] The safety protection isolation panel for oral examination and pharyngeal swab collection of the present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0011] In the picture: 1. Main body of the face screen, 2. Hand strap, 3. Slide, 4. Perforation, 5. Sealing strip. Detailed Implementation

[0012] Example 1 Figure 1As shown, the oral examination and pharyngeal swab collection safety protection isolation panel of this embodiment includes a sheet-like transparent face shield body 1, which is circular in shape. A collection skewer is provided for pharyngeal swab collection. The sheet-like transparent face shield body 1 is placed between the face of the pharyngeal swab collector and the recipient. A foldable, long, strip-shaped plastic hand strap 2 is provided on one side of the face shield body 1, with both ends fixed to one side of the face shield body 1. On the other side of the face shield body 1, perpendicular to the hand strap 2, a slide 3 is provided for the movement of the collection skewer. The outer end of the slide 3 has a circular perforation 4 for easy entry and exit of the collection skewer. The inner end of the slide 3 is located at the center of the face shield body 1. Sealing strips 5 made of elastic material are provided on both sides of the inner side of the slide 3. The width of the sealing strips 5 on both sides of the inner side of the slide 3 is greater than or equal to the width of the slide 3. The elastic material used to make the sealing strips 5 is sponge, rubber, or silicone.

[0013] The collector holds the hand strap with one hand and places the sheet-like transparent face shield 1 between the collector's and the subject's faces. With the other hand, the collector holds the collection swab and pushes the swab head or the handle of another oral medical examination instrument through the perforation 4. Then, the swab stick or handle is pressed horizontally into the slide 3 and moved to the middle position of the face shield 1. At this point, the collector can insert the swab head or handle into the subject's mouth to collect or examine the pharyngeal swab. Because the slide 3 is fixed with sealing strips 5 made of elastic material on both sides, the slide 3 remains sealed even when the stick or handle of the collection skewer is inserted into it. Therefore, the transparent face shield body 1 is always sealed during use, which fundamentally ensures that droplets or aerosols carrying pathogens generated by the patient's breathing are blocked outside the face shield body 1. At the same time, during the use of the collection skewer or other oral long-handled medical examination instruments, the collector can hold the face shield body 1 still with one hand and hold the collection skewer or other oral long-handled medical examination instrument with the other hand, allowing the skewer head or handle to move up, down, left, right, forward, and backward in the oral cavity through the slide 3, making the operation of this embodiment flexible and convenient. In addition, after the collection skewer or handle is removed from the perforation 4, the disadvantage of fixing the collection skewer or other oral long-handled medical examination instrument to the face shield body 1 is avoided.

[0014] Example 2 Figure 2 As shown, the face shield body 1 of the oral examination and pharyngeal swab collection safety protection isolation panel in this embodiment is square in shape, and the perforation 4 is semi-circular. Other structural settings in this embodiment are the same as in embodiment one.
