Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) This invention relates to a nasal plug that prevents nasal secretions from flowing out.

(Prior Art) Conventionally, nasal plugs are generally made of absorbent cotton or open-cell polypropylene.

(Problems to be Solved by the Invention) 17 However, absorbent cotton has water absorption properties, but since it is made of single fibers, the torn fibers adhere to the mucous membrane of the nose and irritate it.

In addition, porous nasal plugs made of open-cell polypropylene are highly water-absorbing and have no risk of tearing, but air circulation is insufficient and the cross section of the end face of the nasal plug has sharp protrusions due to the presence of air bubbles. It has the disadvantage that it touches the inner surface of the nasal cavity and irritates it, and is hard as a whole and does not fit into the nasal cavity.

The present invention focuses on the fact that acetate fibers and polypropylene are both safe medical materials, and utilizes the non-woven fabric made of polypropylene and the properties of long fiber acetate that are not likely to be torn to pieces, thereby producing nasal plugs and mass production thereof. The purpose is to measure the

(Means for solving the problem) A cylinder 1 is formed by rolling a long waved acetate fiber into a cylinder shape.

Then, a roll 3 of polypropylene band-shaped nonwoven fabric 2 is unwound to wrap around the cylinder 1 and advance in one direction, and then both side edges of the band-shaped nonwoven fabric 2 are glued 4 to form a cylinder a.

Next, as shown in Fig. 3, the cylinder a is cut to a certain length L, and the central part of each length L is cut off leaving a part m, and plug bodies 5.5 are formed on the left and right sides thereof. .

In addition, as shown in Fig. 6, a cylinder 1 in which a strong single fiber m1 such as tegus is inserted between long Fjh fibers of waved acetate is used, and the outside of the cylinder is wrapped with a nonwoven fabric 2 of polypropylene. A cylindrical body of a certain length L was cut out at the center, leaving only the single fiber m1, and plugs 5.
form 5.

In addition, as shown in Fig. 7, a cylinder 1 is used in which a spirally curled single fiber m2 made of synthetic resin is inserted between long H& fibers of wavy acetate, and the outside of the cylinder 1 is made of polypropylene. It is wound with a weave 62 to form a cylinder of a certain length, and the central part is cut off leaving the single fiber m2, and plugs 5.5 are formed on the left and right sides of the cylinder.

Alternatively, as shown in FIG. 8, a polypropylene strip-shaped nonwoven fabric is folded in its length direction to form a cylinder 1, and the outside is wrapped with a polypropylene strip-shaped nonwoven fabric 2 to form a cylinder of a constant length L. Then, the central part is cut out leaving a part m3, and plug bodies 5.5 are connected to the left and right sides thereof.

(Function) Although acetate is a long fiber, it has waves, so it gets entangled with each other and maintains the shape of the cylinder 1 well.

Moreover, the cylinder 1 is moved in one direction and wrapped in a band-shaped polypropylene non-woven fabric 2, and both side edges of the band-shaped non-woven fabric are glued to form a cylinder a continuously.

Next, the central part of the cylinder a cut to a certain length L is cut off leaving a part m, so that a pair of left and right plugs 5.5 connected by the part m can be automatically formed, as shown in FIG. As shown in
When this is used for a nasal plug, the long H&fibers of acetate can absorb nasal mucus and retain water well due to the capillary phenomenon between each fiber, and the risk of one plug body 5 becoming clogged deep in the nasal cavity is partially reduced.
It is prevented by

Also, if you pick up and pull out the remaining part m, the left and right plugs will be 5.5 mm.
can be easily extracted to the outside.

(Example) A cylinder 1 is formed by rolling a wavy acetate long fiber into a cylinder shape.

While moving this cylinder 1 in one direction as shown by the arrow in Fig. 2, the cylinder 1 is continuously wrapped while unraveling the band-shaped nonwoven fabric 2 of polypropylene wound into a paper wrapper, and both side edges of the band-shaped nonwoven fabric 2 are hot-melted. The cylindrical body a is formed by gluing.

Next, the cylindrical body a is continuously cut into constant lengths L, and the central portion of each length L is cut off leaving a portion m, thereby producing plugs 5.5 on the left and right sides thereof as shown in FIG. 4.

In this way, one pair of left and right nose plugs can be continuously produced in large quantities.

As shown in FIG. 6, a solid monofilament m1 of a fishing line such as a fishing line is inserted between the wavy acetate long fibers to form a cylinder 1, and the outside of the cylinder is wrapped with a nonwoven fabric 2 of polypropylene.

At this time, if the monofilament ml is glued to the nonwoven fabric 2, there is no risk of it coming out.

Then, the monofilament m1 was excised leaving behind, and plugs 5.
form 5.

Further, the single fiber m1 is made into a single fiber m2 made of synthetic resin and curled in a ds spiral shape, as shown in Figure @7.

In this way, the single fiber m2 not only does not come out from the plug 5, but also expands and contracts and is easily inserted into the left and right nasal cavities.

In addition, in the present invention, as shown in FIG. 8, a polypropylene strip-shaped nonwoven fabric is folded in the length direction to form a cylinder, and the outside of the cylinder is wrapped with a similar polypropylene strip-shaped nonwoven fabric to form a column on both sides of the strip. is glued, and its central part of a certain length L is cut off, leaving only a part, to form plugs 5.5 on the left and right sides thereof.

In this case, the end surface of the plug does not become fluffy like the cut surface of the fibers, so it does not irritate the mucous membrane of the nasal cavity.

Therefore, the nasal plugs shown in FIGS. 6 to 8 can be mass-produced by the same manufacturing method as the nasal plug shown in FIG. 4.

(Effects of the Invention) When the production method of the present invention is used, since the acetate long fibers have waves, they can be easily rolled into a cylinder shape, easily forming a cylinder 1, and a polypropylene strip paper is attached to this cylinder. Not only can a pair of nose plugs made of rolled medically safe material be produced in large quantities, but the left and right plug bodies 5.5 are connected by a part of m for safety, and the end surfaces are made of long acetate fibers. Because it consists of a cross-section, there is no risk of it being torn apart like with conventional monofilament absorbent cotton, and the laminated long acetate fibers elastically expand and contract in the radial direction to fit inside the nasal cavity, allowing each long fiber to The capillary phenomenon in the slits between the nasal passages effectively absorbs nasal secretions and retains water.

In addition, the left and right plugs 5.5 shown in Fig. 6 are solid monofilament m1.
The nose plug connected by this method securely connects the pair of left and right plug bodies 5.5 so that the single fibers are not cut unnecessarily, and is made of synthetic resin made by spirally curling the left and right plug bodies 5.5 as shown in Fig. 7. A nasal plug connected by a single fiber m2 has a length l of the single fiber m2.
Not only does it not come out of the aperture, but it also expands and contracts, so one of the plugs can be inserted deep into the nasal cavity, and the folded cross section of the nonwoven fabric can be seen at the end of the plug 5 shown in Figure 8. Unlike the end surface of conventional open-cell polypropylene porous nasal plugs, it does not produce sharp protrusions and does not irritate the inner surface of the nasal cavity, making it safe and allowing air to circulate well through the folded gap and due to its elasticity. Since it fits into the nasal cavity and can be formed from a single material, a band-shaped nonwoven fabric of polypropylene, it has the effect of reducing the number of parts.
