INFECTION PREVENTION BAG USED WHEN COLLECTING SPECIMEN FROM NASOPHARYNX

Abstract

When collecting a sample of influenza, coronavirus, and the like, the present invention protects a tester from a droplet infection due to a patient’s cough and/or sneeze caused by inserting a swab into nasopharynx to collect the sample from the nasopharynx. At the time of a virus test such as influenza, a patient’s nose and mouth are covered with a bag having a hole through which the testing swab can be passed, and the swab is inserted through the hole from the surface of the bag into the nasopharynx for collecting the sample, and therefore, the droplets scattered by cough and/or sneeze during the test are prevented from being scattered out of the bag, thereby an infection to a practitioner carrying out the test can be prevented.

MODE FOR CARRYING OUT THE INVENTION

[0016] Hereinafter, the best mode for carrying out the present invention will be described.

[0017] FIG. 1 shows a method of carrying out an infection prevention bag used when collecting sample according to the present invention. A bag main body 1 is characterized by having a shape of a bag. The reason is to prevent infected droplets discharged by cough and/or sneeze from being scattered out of the bag when a testing swab is inserted into the nasopharynx. The maximum capacity of a sneeze cannot exceed a lung capacity. At the same time, it is generally known that the lung capacity of adult men and women is from more than or equal to 3000 cc to less than or equal to 4500 cc. Considering these two points as well as the cost of materials and the time and effort for transportation and disposal, it is preferable that the capacity of the bag main body is from more than or equal to 3000 cc to less than or equal to 5000 cc. Also, it is preferable that the capacity of the bag main body for children is from more than or equal to 1600 cc to less than or equal to 2000 cc since the lung capacity of elementary school boys and girls is from more than or equal to 1600 cc to less than or equal to 1850 cc.

[0018] With regard to the material of the bag main body, a material which does not allow a virus to pass therethrough from the inside to the outside of the bag main body 1, that is a material made of a synthetic resin such as vinyl or polyethylene is most suitable. Further, a permeable material capable of observing the nasopharynx is most suitable in order to improve the efficiency of an operation for collecting sample.

[0019] A size of a hole 2 through which a testing swab 3 is passed depends on the size of the testing swab 3. The hole 2 should be as small as possible in accordance with the size of the testing swab 3. This is because there is a high probability that the virus is scattered from the hole 2 when a patient 6 sneezes.

[0020] Since there is a possibility that the droplets may be scattered due to the internal air pressure even if a circular hole is small, for example, a cut through which the testing swab 3 is passed can be made in the bag instead of the circular hole. The shape of the cut is not limited to a straight line as shown in the hole 2 of FIG. 3. As long as the testing swab 3 can be passed therethrough, the shape of the hole 2 should not be linear, but may be, for example, a Y-shaped or a cross-shaped cut.

[0021] In order to prevent the droplets from being scattered from the hole 2, the possibility of scattering of droplets can be more reduced by using a check valve 8 in the hole 2 as shown in FIG. 5 even when sneezing after the testing swab 3 is taken out.

[0022] The below shows an easier method than the method of using the check valve 8. In FIG. 6, the upper part shows an outside of the bag main body, the lower part shows an inside of the bag main body, and the right side shows a bag mouth side to be put on a mouth of a face of a patient. In order to stick and fix a simple droplet splash prevention valve 9 closing the hole 2 only to the inside of the bag main body 1 at the bag mouth side thereof, the simple droplet splash prevention valve 9 is stuck to a sticking part 10 on the bag mouth side so that the bag bottom side of the simple droplet splash prevention valve 9 is set free without fixing. As a result, the simple droplet splash prevention valve 9 can prevent the air generated inside of the bag main body 1 from flowing out of the hole 2 by a sneeze, and reduce the scattering of the virus from the hole 2, not only when the testing swab 3 is not inserted but also when the testing swab 3 is inserted.

[0023] With regard to the position of the hole 2, when explaining based on the front view of the bag main body of FIG. 2, it is preferable that the distance from the position of the hole 2 to the bag mouth part to be put on the face in a direction toward the bag bottom part is 4 cm or more. In this connection, the operation for collecting the sample cannot be properly carried out when the position of each naris of the nasopharynx from which the sample is to be collected and the position of the hole 2 of the bag main body 1 cannot overlap to each other. Thus, the distance from the hole 2 to the bag mouth part is important. Further, when a synthetic resin material such as vinyl or polyethylene is used for the bag main body, the bag main body is flexible. Therefore, even if the distance from the hole 2 to the bag mouth part to be put on the face is 4 cm or more and the hole is formed near the bag bottom part, the operation for collecting sample will not be disturbed since the capacity of the bag is in a degree of 5000 cc.

[0024] As described above, it is difficult to find the hole 2 since the hole is very small, and therefore, it is preferable to put a mark 4 showing a position of the hole. Although the mark 4 can be a printing, a sticker or the like to close the hole 2 that can be easily peeled off may be stuck to the hole 2 to show the position of the hole.

[0025] When the hole 2 is opened in the bag main body 1, the bag main body 1 may be punched through the bag main body by a hole punch or the like in order to simplify a manufacturing process. At this time, a plurality of holes may open, and in that case, it is preferable to stick a peelable sticker to each of the holes 2.

[0026] Although the bag main body 1 of FIGS. 1, 2, 4, and 5 shows a structure with an ear hook for wearing it on the face, the structure for wearing it on the face 5 is not necessarily required if the patient 6 can hold the bag main body 1 with both hands when collecting sample. However, such a structure is necessary for testing a hand handicapped person or preventing the virus from being scattered by releasing the hands when sneezing. The structure for wearing the bag on the face can be selected freely so long as the bag can be worn to the face.
