JPH0217082A - Nose plug - Google Patents

Abstract

PURPOSE:To prevent nose plugs from being deeply inserted into nostril by a method wherein a plasticizer is added at the central part of each column body formed by bundling long fibers made of acetate and a nonwoven fabric made of polypropylene is wrapped around the column body. CONSTITUTION:Each hook-shaped bend body 5 is made by upward-bending the middle part of a connecting wire 4 made of stainless steel and by downward- bending both the right end left end of the wire 4. After this hook-shaped bend body 5 is flatly wrapped by polypropylene, it is fitted with each column body 1 by being thrust at the central part 2 of the column body 1. Not only the column body 1 has good ventilation since it bundles long fibers made of acetate, also the long fibers of its inside is kept in column shape for a long period and not torn to pieces like absorbent wadding since the periphery of the body 1 is wrapped by a nonwoven fabric 3 made of polypropylene. Besides, both ends of the wire are well thrust into each the column body 1 and held since the central part 2 with a plasticizer added is properly hard and has elasticity. Furthermore, since the periphery part of the body 1 is not added with the plasticizer, each nose plug is soft and well fits the form of nostril different from a nose plug made of synthetic resin with continuous foams.

Description

Detailed Description of the Invention (Field of Industrial Application) This invention relates to a nasal plug for filtering dust, pollen, etc. floating in the air, and for preventing nasal secretions from flowing out.

(Prior Art) Conventionally, nasal plugs made of absorbent cotton or open-celled, porous synthetic resin are generally used.

(Problem B to be Solved by the Invention) However, although absorbent cotton has water absorption properties, since it is made of short fibers, the mis is easily torn off, and this adheres to the mucous membrane of the nasal cavity and irritates it.

In addition, nasal plugs made of synthetic resin such as open-cell polypropylene are highly absorbent and have no risk of tearing.
Not only is the air circulation insufficient, but the cross section of the end of the S stopper produces sharp protrusions due to the presence of air bubbles, which can touch and irritate the inner surface of the nasal cavity, and the entire body is hard and does not fit into the nasal cavity. be.

The present invention focuses on the fact that acetate fiber is a safe medical material along with polypropylene, and utilizes the property of non-woven fabric made of polypropylene and long tli fiber acetate without fear of tearing, thereby forming a nasal plug. , the purpose is to prevent the nasal plug from being inserted too deeply into the nasal cavity.

(Means for Solving the Problem) A plasticizer is added to the center 2 of a column 1 made of bundled long acetate fibers, and the outer periphery of the column is covered with a nonwoven fabric 3 of polypropylene (Claim 1).

Then, the central part of the narrow connection &i4 made of stainless steel is curved upward, and the plastic material of the column 1 is added to the hook-shaped bent parts 5 on the left and right ends covered with synthetic resin material. The portion 2 is inserted and connected (Claim 2).

(Function) The aggregate of long acetate fibers in the central part 2 of the column 1 becomes rigid and elastic by adding a plasticizer.
When inserted through the hook-shaped bent portion of the connection line between the left and right nasal plugs as shown in claim 2, the hook-shaped bent portion is tightly connected to the left and right nasal plugs due to its elasticity, and the nasal plug is not pulled out unnecessarily.

Furthermore, breathing air flows well through the gaps between the long acetate fibers, and during this time, dust, pollen, or nasal secretions adhere to the long fibers and are removed.

(Example) As shown in Figure 3, about 25,000 long acetate fibers with waves of about 1 cm in length are laid out, a plasticizer is added to the center part 2, and a column is formed. 1, and its outer periphery is covered with a nonwoven fabric 3 made of polypropylene.

In this way, the gap between the length m's becomes about 0.3 microns, and air can circulate well through this gap from the starting end to the ending end of the column 1.

Triacetin is added as a plasticizer to the center portion 2 of the column to impart appropriate hardness and elasticity to the acetate fibers.

Therefore, as shown in Fig. 1, the stainless steel connecting wire 4
The central part of the is curved upward, and the left and right ends are bent downward to form a hook-shaped bent part 5.
is flattened with polypropylene and inserted into the center 2 of the column 1 to connect the column 1 to the hook-shaped bent portion 5.

(Effects of the Invention) The column l according to the invention of claim 1 not only has good air circulation because it bundles the length M of acetate, but also has an outer circumference covered with a polypropylene nonwoven fabric 3, so that the inner length can be reduced. The fibers maintain a columnar shape for a long time and do not tear apart like absorbent cotton, and the center portion 2 to which the plasticizer is added is appropriately hard and elastic, so that the fibers can be connected to the columnar body 1 as in claim 2 of the present invention. The tip of the wire can be easily inserted and retained, and since no plasticizer is added to the periphery of the column, it is soft, and unlike conventional open-cell synthetic resin nasal plugs, it fits well into the shape of the nasal cavity. Since the end face of the upper column 1 is made of a cross section of long fibers covered with non-woven material '1rj3, there is no sharp protrusion on the end face unlike in conventional open-cell synthetic resin nasal plugs.

Next, according to the present invention of claim 2, the left and right columns l are inserted and connected to the hook-shaped bent portion 5, so that the column l is prevented from entering the deep part of the nasal cavity unnecessarily because it is blocked by the hook-shaped bent portion. Not only is it safe, but the part that appears outside across the nasal bridge that separates the left and right nasal cavities is only the central part of the connecting line 4, so there is no risk of it being visually noticeable even when the nose plug of the present invention is used. Moreover, since the hook-shaped bent portion 5 of the connecting wire 4 is covered with synthetic resin and formed thick, the tip of the hook-shaped bent portion is attached to the inner surface of the nasal cavity, compared to inserting the connecting wire 4 directly through the column 1. There is no risk of injury if touched, and it is difficult to remove, and since it is made of acetate or polypropylene, it is medically safe.
