Description

  The present invention relates to an earlobe suction attachment attached to a tip of a suction tube of an earlobe suction device for suctioning earwax collected in an ear canal.

  The earwax is formed by mixing keratinized epidermal cells, hair, dust, etc. which have fallen off with secretions from the earwax gland and sebaceous gland in the ear canal. Ear plugging is a disease in which a large amount of earlobe accumulates and solidifies, causing the hole in the ear to narrow or clog. Symptoms of earlobe embolism include ear obstructions, deafness, tinnitus, ear-speaking symptoms, and other ear symptoms, as well as unusual symptoms such as throat discomfort, stomach discomfort and nausea.

  Among the earlobe suction devices, there is a type equipped with an electric motor for suctioning earlobes, and a device has been proposed in which a cylindrical nozzle is inserted into the ear canal to suck in the earlobes (Patent Document 1). However, since the nozzle tip inserted into the ear canal is simply a circular tube, it requires a certain technique to remove the earwax, and there is a problem that it is difficult to remove the earwax properly.

  There has been proposed an earpick type in which the tip is curved as the shape of the nozzle tip of the earlobe suction tool inserted into the ear canal (Patent Document 2). However, sneezing or the like may occur when the nozzle tip stimulates the inside of the sensitive ear canal, and furthermore, there is a high possibility that the inside of the ear canal is damaged by the nozzle tip.

  The present invention has been made in view of such problems, and provides an earlobe suction attachment which can be detachably attached to the tip of a suction tube of an earlobe suction device and can remove earwax in the ear canal easily and appropriately. The purpose is to

  The earlobe suction attachment according to the present invention is a flexible earlobe suction attachment that is removably attached to the tip of the suction tube of the earlobe suction device, inserted into the ear canal, and sucking foreign objects in the ear canal. A tubular body having a hollow portion penetrating in the longitudinal direction, and a trumpet shaped skirt portion provided at the distal end portion of the tubular body and having an outer diameter increasing toward the distal end is characterized.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the accompanying drawings, which are for the purpose of facilitating the understanding of the principle of the present invention, and the scope of the present invention is as follows: The present invention is not limited to the embodiment, and other embodiments in which a person skilled in the art substitutes the configuration of the following embodiments as appropriate are also included in the scope of the present invention.

  FIG. 1 shows an earlobe suction attachment 900 according to the present embodiment. The earlobe suction attachment 900 has a cylindrical body 100 having a hollow portion penetrating in the length direction, and a trumpet shaped skirt portion 200 provided at the tip end of the cylindrical body 100 and having an outer diameter increasing toward the tip. .

  The shape of the cylindrical body 100 is not particularly limited as long as it can be inserted into the ear canal. For example, assuming that the thickness of the cylindrical body 100 is 0.2 mm, the outer diameter is 2.5 mm to 6.5 mm and the inner diameter is 2.3 mm The cross-sectional shape of ~ 6.3 m is a circle. In addition, since the cross-sectional shape of the human ear canal is slightly elliptical, the longitudinal major diameter is about 9.0 mm, and the lateral minor diameter is about 7.0 mm, it is possible to make the cross-sectional shape of the cylindrical body 100 elliptical.

  The material for the earlobe suction attachment 900 is not particularly limited as long as it is flexible. For example, natural rubber, polychloroprene, polybutadiene, butadiene styrene rubber, butadiene acrylonitrile rubber, polyisoprene, chlorosulfonated polyethylene, poly Isobutylene, isobutylene isoprene rubber, acrylic rubber, urethane rubber, fluororubber, silicone rubber and the like can be used, preferably natural rubber.

  The cylindrical body 100 and the skirt portion 200 are integrally configured, and the rubber hardness thereof is, for example, not less than 55 and not more than 65 according to JIS K 6253 (2006).

  The earwax has a dry earwax and a wet earwax, but both can be suctioned by the earwax suction attachment 900. The dry earwax is a dry, gray-white, bowl-like earwax with about 7% of the Japanese being the owner of the dry earwax. Wet earwax is a brown, candy-like wet earwax, and about 90% of Western Europeans have wet earwax.

  The usage mode of the earlobe suction attachment 900 is as follows. That is, the proximal end located opposite to the distal end of the cylindrical body 100 in the length direction is attached to the distal end of the suction tube of the earlobe suction device by insertion or the like. Then, the earlobe suction attachment 900 is inserted into the ear canal with the skirt portion 200 at the top. The skirt portion 200 has a trumpet shape in which the outer diameter increases toward the tip, and therefore, when inserted into the ear canal, it is possible to scrape the earwax attached to the wall surface in the ear canal at the peripheral portion on the bottom side. The earlobe present in the external auditory canal is taken into the trumpet-shaped skirt portion 200, but even the relatively large earlobe is taken into the skirt portion 200 by suction and stably fixed. The earwax taken into the skirt portion 200 can be sucked and removed stably without spill when it is pulled out of the ear canal.

  FIG. 2 shows an earlobe suction attachment 900 according to another embodiment. As shown in FIG. 2, the trumpet-shaped skirt portion 200 is provided with a plurality of slits 210 which are slits formed from the distal end side to the proximal end side. In FIG. 2, four slits 210 are provided at regular intervals of 90 degrees in the circumferential direction.

  The usage mode of this earlobe suction attachment 900 is as follows. That is, since the skirt portion 200 is provided with the plurality of slits 210, when inserting into the external ear canal, each fin of the skirt portion 200 divided by the plurality of slits 210 adheres to the earwax attached to the wall surface in the external ear canal Scrape. The external auditory canal has an S-shaped bent shape, but depending on the human being, the degree of S-shaped bending may be large, and each fold of the skirt portion 200 divided by the plurality of slits 210 is curved S This is particularly effective because it softly abuts inside the letter-shaped ear canal and scrapes off earwax attached to the wall surface in the ear canal.

Example 1
An earlobe suction attachment according to this example was prepared as shown in FIG. The material was natural rubber, and the type A durometer hardness of JIS K 6253 (2006) was 60. The length of the cylinder was 50.0 mm, the height of the skirt was 6.0 mm, and the length of the bus bar was 7.0 mm. The cylinder had an outer diameter of 5.0 mm and an inner diameter of 4.8 mm, and the cross-sectional shape was a circle.

  As shown in FIG. 4, in a 10 cc plastic syringe with a tube diameter of 1.0 cm and a length of 5.0 cm, a dumpling-like crushed Japanese confection with a water content of 10% by weight was packed as a model-dried earwax.

  Next, insert the prepared earlobe suction attachment into the tip of the suction tube of the medical earlobe aspirator and attach it, insert the earlobe suction attachment into the plastic syringe with the skirt portion at the top, and model dry earlobe I tried to aspirate. As shown in FIG. 5, the model dry earwax attached to the wall in the syringe was scraped off when inserted into the plastic syringe, and the model dry earwax was taken in the skirt by suction and stably fixed by suction.

(Example 2)
Using the earlobe suction attachment prepared in Example 1, aspiration removal of the earlobes of multiple earlobe plugging patients was attempted. As shown in FIG. 6, the inside of the ear canal of the patient with earlobe plugging prior to suction removal was blocked with earlobe.

  The prepared earlobe suction attachment is inserted into and attached to the tip of the suction tube of the medical earlobe aspirator, and the earlobe suction attachment is inserted into the ear canal with the skirt portion at the top and suctioned, as shown in FIG. Thus, a large amount of earwax could be removed properly in a short time.

  It can be used for earlobe suction removal.
