Hereinafter, a first embodiment of the present invention will be described in detail.

Figure 1 is a perspective view showing a nose plug according to a first embodiment of the present invention, Figure 2 is a cross-sectional view showing a nose plug according to a first embodiment of the present invention, Figure 3 is a nose plug according to the first embodiment of the present invention 4 is a perspective view showing a state in which the procedure and the inspection instrument are penetrated, and FIG. 4 is a cross-sectional view showing the state in which the procedure and the inspection instrument are penetrated through the nose plug according to the first embodiment of the present invention.

1 to 2, the nose plug according to the first embodiment of the present invention includes a nose plug body 10 and a sealing member (20).

Overall, the nose plug body 10 is worn on the nostrils, and inside the nose plug body 10, an inlet 11 for entry and exit of a procedure such as an endoscope and an inspection instrument 1 is formed, and a sealing member ( 20) seals the entrance hole 11. Therefore, when the procedure and inspection instrument 1, such as an endoscope, enters and exits the entrance hole 11 of the nose plug body 10, the sealing member 20 blocks the flow of droplets in the entrance hole 11, prevent infection; In particular, the sealing member 20 is fixed in close contact with the outer circumferential surface of the procedure and inspection instrument 1 even in a state in which the procedure and inspection instrument 1 is penetrated, thereby blocking the flow of droplets in the entry hole 11, infection can be prevented.

The nose plug body 10 serves to be worn on the nostrils.

For example, the nose plug body 10 may have a shape in which the diameter increases in the direction in which it is discharged from the nostril. In this case, when the nose plug body 10 is inserted into the nostril, it is possible to prevent the nose plug body 10 from being completely inserted into the nostril.

Inside the nose plug body 10, while the nose plug body 10 is worn in the nostrils, an inlet 11 that communicates with the nasal passages is formed.

For example, the entrance hole 11 may be formed in a penetrating shape along the longitudinal direction of the nose plug body 10 , and the procedure and inspection instrument 1 may be entered into the entrance hole 11 . Therefore, the operator can check the state of the mucous membrane of the nasal cavity by using the procedure and the inspection instrument 1 that has entered the entrance and exit holes 11, and through this, it is possible to identify respiratory diseases.

The sealing member 20 serves to block the flow of droplets in the entrance hole 11 when entering and exiting the entrance hole 11 of the procedure and inspection instrument 1 . The sealing member 20 may include a flexible material or may be made of a flexible material.

For example, the sealing member 20 may be formed in the form of a film covering a specific depth of the entrance hole 11 . When the procedure and inspection instrument 1 that has entered the entrance hole 11 is penetrated through the sealing member 20 , the sealing member 20 is closed by the elastic force of the sealing member 20 of the procedure and inspection instrument 1 . It is attached to the outer circumferential surface and fixed. As a result, when entering and exiting the entry/exit hole 11 of the procedure and inspection device 1, the sealing member 20 can block the droplet flow in the entry/exit hole 11, as well as the outer peripheral surface of the procedure and inspection device 1 can be firmly supported.

As another example, the sealing member 20 may include a plurality of cutouts 21 cut in a radial direction from the center of the membrane shape. The sealing member 20 may be separated into a plurality of unit members 22 by the plurality of cutouts 21 . When the operation and inspection mechanism 1 entered into and out of the entrance hole 11 is penetrated through the plurality of unit members 22, the plurality of unit members 22 are bent in the direction in which the operation and inspection mechanism 1 enters and exits. It is fixed in close contact with the outer circumferential surface of the procedure and inspection instrument 1 by the elastic restoring force.

At this time, the operation and inspection mechanism 1 can move freely on the plurality of unit members 22. In this way, even when the operation and inspection mechanism 1 freely moves, the plurality of unit members 22 can move freely on the operation and inspection It maintains a state in close contact with the outer circumferential surface of the mechanism (1). Therefore, when entering and exiting the entry/exit hole 11 of the procedure and inspection device 1, a plurality of unit members 22 can block the flow of droplets in the entry/exit hole 11, as well as free movement of the procedure and inspection device 1 can make movement possible.

Furthermore, the sealing member 20 may be composed of a plurality. A plurality of these sealing members 20 may be arranged along the other end from one end of the entrance hole (11). Here, the plurality of sealing members 20 may have different diameters. For example, the plurality of sealing members 20 may have a relatively large diameter as they are disposed from one end of the entrance hole 11 to the other end. . In other words, the plurality of sealing members 20 may have a relatively large diameter toward the direction in which the procedure and inspection instrument 1 is entered.

In addition, the plurality of sealing members 20 are formed in the form of a film covering a specific depth of the entrance hole 11 . Therefore, the diameter of each sealing member 20 may be determined according to the diameter of the entrance hole (11). Therefore, the entrance hole 11 may have a shape in which the cross-sectional area increases from one end of the entrance hole 11 to the other end, and therefore, the plurality of sealing members 20 move from one end of the entrance hole 11 to the other end. As it is disposed, it may have a relatively large diameter. In other words, the entrance hole 11 may have a shape in which the cross-sectional area increases in the direction in which the procedure and inspection instrument 1 is entered, and therefore, a plurality of sealing members 20 are provided with the procedure and inspection instrument 1 It may have a relatively large diameter as it goes in the direction in which it is entered.

As such, the plurality of sealing members 20 do not greatly limit the tilting angle of the procedure and inspection instrument 1 during the initial entry and exit of the entrance hole 11 of the procedure and inspection instrument 1, but then, the procedure and inspection instrument By gradually limiting the tilting angle of the procedure and inspection instrument (1) as the distance (1) enters and exits the entrance hole (11) increases, the end of the procedure and inspection instrument (1) contacts and stimulates the inner wall of the nostril It can help prevent sneezing.

In this regard, the first sealing member 20a, the second sealing member 20b, and the third sealing member 20c will be described in more detail by taking examples.

1 to 2 , the first sealing member 20a is disposed at one end of the entry hole 11 and has a first diameter, and the second sealing member 20b has one end and the other end of the entry hole 11 . It is disposed between and has a second diameter smaller than the first diameter, and the third sealing member 20c is disposed at the other end of the entrance hole 11 and has a third diameter smaller than the second diameter.

At this time, when entering and exiting the entrance hole 11 of the procedure and inspection instrument 1, the procedure and inspection instrument 1 penetrates the first sealing member 20a first, and the first sealing member 20a Since the tilting angle of the inspection mechanism 1 is not significantly limited, the operation and inspection mechanism 1 can be easily tilted. After that, the operation and inspection mechanism 1 penetrates through the second sealing member 20b, and the second sealing member 20b limits the tilting angle of the operation and inspection mechanism 1 to the second diameter, so that , the tilting angle of the procedure and inspection instrument (1) is limited to the primary. Thereafter, the operation and inspection mechanism 1 penetrates through the third sealing member 20c, and the third sealing member 20c limits the tilting angle of the operation and inspection mechanism 1 to the second diameter, so that , the tilting angle of the procedure and inspection instrument (1) is limited to the second. Thereafter, the procedure and inspection mechanism 1 penetrates the entrance hole 11 in a state in which the milting angle is limited by the first sealing member 20a to the third sealing member 20c. As a result, it is possible to prevent sneezing by contacting and stimulating the inner wall of the nostril with the distal end of the procedure and inspection instrument 1 .

Referring to Fig. 4, the operation of this embodiment will be described.
