Definitions
- the present invention relates to a wiping tip for cleaning a male connector preferably used in enteral nutrition.
- Enteral nutrition is known as a method of administering a liquid substance containing nutritional supplements and drugs to patients who cannot eat food by mouth.
- a catheter is placed in a patient with a catheter inserted from outside the body into the gastrointestinal tract (for example, stomach).
- a nasal catheter inserted through the nose of a patient a PEG (Percutaneous Endoscopic Gastrostomy) catheter inserted into a gastrostomy formed in the abdomen of a patient, and the like are known.
- Liquids such as nutritional supplements, liquid diets (commonly referred to as "enteric nutritional supplements"), or drugs are administered to the patient via a catheter.
- the container that stores the liquid material is connected to the catheter (nasal catheter, PEG catheter, etc.) placed in the patient.
- a connector consisting of a male connector and a female connector is used.
- the male connector 910 shown in FIGS. 11A and 11B and the female connector 920 shown in FIGS. 12A and 12B are used.
- the male connector 910 of FIGS. 11A and 11B has a tubular male member 911 and an outer cylinder 913 surrounding the male member 911.
- the male member 911 and the outer cylinder 913 are connected to each other via a bottom plate 914 protruding in a flange shape along the radial direction from the base end portion of the male member 911.
- the outer peripheral surface 912 of the male member 911 is a tapered surface (so-called male tapered surface) whose outer diameter decreases as it approaches the tip.
- the male member 911 is provided with a flow path 917 that penetrates the male member 911 along the longitudinal direction thereof.
- a female screw 915 is provided on the inner peripheral surface of the outer cylinder 913 facing the male member 911.
- the female screw 915 is a right-hand screw.
- the female connector 920 of FIGS. 12A and 12B has a hollow cylindrical tubular portion (female member) 921.
- the inner peripheral surface 922 of the tubular portion 921 is a tapered surface (so-called female tapered surface) whose inner diameter increases as it approaches the tip.
- a spiral protrusion (male screw) 925 is provided on the outer peripheral surface of the tubular portion 921.
- the male connector 910 and the female connector 920 are connected by inserting the male member 911 into the tubular portion 921 and screwing the female screw 915 and the spiral protrusion 925. Since the outer peripheral surface 912 of the male member 911 and the inner peripheral surface 922 of the tubular portion 921 are tapered surfaces having the same diameter and taper angle, they are in liquid-tight surface contact.
- a female connector 920 is used as a connector on the upstream side (container side) and a male connector 920 is used as a connector on the downstream side (patient side) with respect to the flow direction of the liquid substance.
- the outer cylinder 913 surrounds the male member 911, and a female screw 915 is provided on the inner peripheral surface of the outer cylinder 913. Therefore, after performing the enteral nutrition method, a liquid substance (enteral nutritional supplement) tends to remain in the gap 916 between the male member 911 and the outer cylinder 913 (for example, in the valley of the female screw 915).
- the male connector 910 When the male connector 910 is provided at the upstream end of the catheter inserted into the patient, the male connector 910 is indwelled in the patient for a long period of time together with the catheter. If the male connector 910 continues to be indwelled in the patient with residual liquid material, the male connector 910 can become unsanitary. Further, the solidified product obtained by drying and solidifying the liquid material on the male connector 910 prevents the male connector 910 and the female connector 920 from being reconnected. Therefore, it is desirable to clean the male connector 910 cleanly.
- Patent Document 1 describes a wiping tip for cleaning the male connector 910.
- the wiping tip includes a tubular portion having water absorption.
- the tubular portion is inserted into the gap 916 between the male member 911 and the outer cylinder 913.
- the liquid material remaining in the gap is absorbed by the tubular portion and wiped off.
- Patent Document 1 describes that the tubular portion is made of a foam such as urethane or polyvinyl alcohol or a non-woven fabric, and can be manufactured by press molding, transfer molding, or the like. However, it is difficult to mold the foam or non-woven fabric of the above material into a tubular portion having a desired strength. If the tubular portion is too soft, the tubular portion is easily deformed when inserted into the gap 916 between the male member 911 and the outer cylinder 913. Therefore, the tubular portion cannot be inserted deep enough to reach the bottom plate 914, and it is difficult to wipe off the liquid matter adhering to the vicinity of the bottom plate 914. On the other hand, if the tubular portion is too hard, the tubular portion cannot be deformed according to the male connector 910.
- a foam such as urethane or polyvinyl alcohol or a non-woven fabric
- the conventional wiping tip has a problem that all the liquid matter adhering to the male connector 910 cannot be wiped off.
- An object of the present invention is to provide a wiping tip capable of cleaning a male connector provided with a female screw so as to surround a male member.
- the wiping tip of the present invention includes a hollow tubular body and a wiping cotton provided on the tubular body.
- the wiping cotton constitutes a thin film portion that covers the opening at the tip of the tubular body, and an outer peripheral portion that extends from the thin film portion and covers the outer peripheral surface of the tubular body over a predetermined length from the tip.
- the tubular body allows the wiping cotton to be deeply inserted into the gap between the male member and the outer cylinder.
- a wiping cotton is interposed between the tubular body and the male connector. Therefore, according to the present invention, it is possible to clean the male connector provided with the female screw so as to surround the male member.

- FIG. 12A is a perspective view of a female connector used as a container-side connector in enteral nutrition.
- FIG. 12B is a cross-sectional view taken along a plane including the central axis of the female connector.
- the wiping cotton may be provided at both ends of the tubular body.
- the male connector can be cleaned cleanly, for example, by sequentially using wiping cotton at both ends.
- the wiping cotton may be provided only at one end of the tubular body. Such an embodiment is advantageous for inducing the user to dispose of the wiping tip of the present invention.
- the wiping cotton may be impregnated with a cleaning liquid. Such an embodiment is advantageous for cleaning the male connector cleanly.
- a slit may be provided that penetrates the thin film portion. Such an aspect is advantageous, firstly, to facilitate the male member to break through the thin film portion, and secondly, to wipe and clean the outer peripheral surface of the male member evenly.
- the tubular body may be stuffed with cotton. Such an embodiment is advantageous for wiping off the liquid matter adhering to the tip of the male member.
- the wiping tip of the present invention may include a rod-shaped rod.
- a hole having a predetermined length may be provided from the end surface of the rod along the longitudinal direction of the rod.
- the portion of the rod provided with the hole may be the tubular body.
- the part of the rod excluding the tubular body is solid and has relatively high strength.

- the wiping tip of the present invention may be provided with the tubular body provided with the wiping cotton at one end and a handle at the other end. Such an aspect is advantageous in improving the cleaning work efficiency and ensuring the cleanliness of the wiping cotton.
- the wiping tip of the present invention wipes a male connector having a tubular male member, an outer cylinder surrounding the male member, and a female screw provided on an inner peripheral surface of the outer cylinder facing the male member. It may be used for cleaning. According to such an embodiment, the wiping tip of the present invention can be used to clean a male connector used as a patient-side connector in enteral nutrition.
- the thin film portion may be penetrateable by the male member.
- the tubular body may be inserted into the gap between the male member and the outer cylinder. According to this aspect, the tip of the male member and the surfaces of the male member and the tubular body that define the gap can be wiped and cleaned.
- the wiping tip of the present invention may be configured such that the thin film portion is penetrated by the male member and bent into the tubular body. According to this aspect, the bent thin film portion wipes off the liquid matter adhering to the outer peripheral surface of the male member.
- the outer diameter of the outer peripheral portion may be larger than the inner diameter of the female screw. Such an embodiment is advantageous for wiping off the liquid matter adhering to the groove of the female screw.
- the outer diameter of the tubular body may be the same as or smaller than the inner diameter of the female screw. According to such an embodiment, the wiping tip can be deeply inserted into the gap between the male member and the outer cylinder. This is advantageous for cleaning the male connector cleanly.
- the inner diameter of the tubular body may be the same as or larger than the maximum outer diameter of the outer peripheral surface of the male member.
- the wiping tip can be deeply inserted into the gap between the male member and the outer cylinder. This is advantageous for cleaning the male connector cleanly.
- the thin film portion broken by the male member can be reliably interposed between the male member and the tubular body. This is advantageous in preventing the tubular body from damaging the outer peripheral surface of the male member.
- FIG. 1A is a perspective view of the wiping tip 1 according to the first embodiment of the present invention.
- FIG. 1B is a cross-sectional view of the wiping tip 1.
- the wiping tip 1 includes an elongated rod-shaped tubular body (rod) 10 extending straight, and wiping cotton (wat) 20 provided at both ends of the tubular body 10.
- the tubular body 10 has a hollow tubular shape in which a hole 11 extending along the longitudinal direction of the tubular body 10 penetrates the tubular body 10.
- the hole 11 is a through hole connecting both ends of the tubular body 10, and communicates with the outside world through openings at both ends of the tubular body 11.
- Both the outer peripheral surface and the inner peripheral surface of the tubular body 10 have a circular cross-sectional shape.
- the inner and outer diameters of the tubular body 10 are constant in the longitudinal direction of the tubular body 10.
- the tubular body 10 has a strength that does not substantially deform when the user pinches it with a finger or applies a bending force or a twisting force.
- the material of the tubular body 10 is not limited, but resin materials such as polyethylene, polypropylene, polycarbonate, styrene ethylene, polyethylene terephthalate, polybutylene terephthalate, butylene styrene block copolymer, polyacetal, polyamide, and rigid polyvinyl chloride are used. Among these, polyolefin resins such as polyethylene and polypropylene are preferable. It is preferable that the tubular body 10 is integrally manufactured as a whole by injection molding the resin material.
- the wiping cotton 20 is a cotton-like material in which fibers are entwined.
- the material of the cotton wool 20 is not limited, but a material having water absorption such as cotton and rayon can be used, and absorbent cotton can be particularly preferably used.
- the wiping cotton 20 constitutes a thin film portion 21 that covers the opening at the tip of the tubular body 10 and an outer peripheral portion 23 that extends from the thin film portion 21.
- the outer peripheral portion 23 covers the outer peripheral surface of the tubular body 10 from the tip end of the tubular body 10 over a predetermined length.
- the wiping cotton 20 is provided at the end of the tubular body 10 so that the thin film portion 21 and the outer peripheral portion 23 are continuously formed.
- the method of attaching the wiping cotton 20 to the tubular body 10 is not limited, and may be substantially the same as the method of manufacturing a cotton swab, for example. That is, a cotton-like material having a predetermined size is pressed against the tip of the tubular body 10 so as to close the opening of the tubular body 10, and the tubular body 10 is rotated to push the cotton-like material to the outer periphery of the tubular body 10. Wrap it around the surface.
- the wiping cotton 20 may be firmly fixed to the tubular body 10 by using an adhesive such as PVA (polyvinyl alcohol). It is preferable that the adhesive is applied only to a part of the outer peripheral portion 23 (for example, the portion of the outer peripheral portion 23 that is farthest from the tip of the tubular body 10).
- the wiping cotton 20 is soft and elastic except where the adhesive is applied.
