Definitions

• the object of the present invention is to provide a cap for medical instruments that overcomes the problems inherent in the conventional technology described above and makes it easy to confirm that a urethral catheter has reached the bladder.
• the intermediate portion may incorporate either a magnet or an iron member
• the body portion and the lid portion may incorporate either the magnet or the iron member.
• the magnet and the iron member may be assembled so that the force that attracts the middle part and the main body part is stronger than the force that attracts the middle part and the lid part.
• the present invention provides a cap for a medical device that allows easy confirmation that a urethral catheter has reached the bladder.
• connection plug body 10 has a connection part 11 that can be connected to an external member such as a urethral catheter or a urine collection bag via a tube or the like.
• the connection plug body 10 has a urine discharge flow path (first flow path) 14 that penetrates from a base end 12 for fluid connection to an external member to a tip end 13 on the opposite side.
• the connection plug body 10 has a seat 15 on the tip end 13 side on which the intermediate part 20 is placed.
• the urine discharge flow path 14 is formed in a circular shape so as to penetrate the center of the connection part 11 and the seat 15, and the tip end 13 protrudes from the seat 15.
• the tip end 13 is formed in a cylindrical shape with a flange 13A on the outer circumferential surface, protrudes from the seat 15, and is provided so as to be able to fit with the intermediate part 20.
• the intermediate section 20 is provided on the connection plug body 10 so as to be swingable by the first hinge section 21, and is formed so as to be able to fit with the connection plug body 10 when closed with the first hinge section 21 as a fulcrum.
• the intermediate section 20 has a cylindrical outer wall 22 formed to have approximately the same diameter as the outer periphery of the seat section 15 of the connection plug body 10, and an exhaust flow path (second flow path) 24 formed in a cylindrical section 23 having approximately the same diameter as the tip section 13 of the connection plug body 10 is formed approximately coaxially with the outer wall 22.
• the cylindrical portion 23 is formed so that its body-side end 26, which is the end on the connection plug body 10 side, can be fitted into the tip portion 13 of the connection plug body 10, and when fitted into the tip portion 13, the body-side end 26 is hooked onto the flange 13A.
• the connection plug body 10 and the intermediate portion 20 are arranged so that the tip portion 13 of the connection plug body 10 and the cylindrical portion 23 of the intermediate portion 20 can be fitted into each other.
• the cylindrical portion 23 is also formed so that its lid-side end 27 can be fitted into the lid portion 30.
• the intermediate section 20 has an intermediate knob 25 formed on the opposite side of the cylindrical section 23 from the first hinge section 21, which is operated by the user when opening and closing the intermediate section 20 relative to the connection plug main body 10. Because the exhaust flow path 24 is located between the intermediate knob 25 and the first hinge section 21, when the user operates the intermediate knob 25 to swing the intermediate section 20 around the first hinge section 21 as a fulcrum, the cylindrical section 23 of the intermediate section 20 can be fitted into the tip section 13 of the connection plug main body 10 with a small force.
• the cylindrical portion 23 has a hydrophobic filter 28 in the exhaust flow path 24 that allows gas to pass but does not allow liquid to pass through, and the exhaust flow path 24 is formed so that the cross section of the flow path at the lid end 27 side of the hydrophobic filter 28 is smaller than that at the body end 26 side of the hydrophobic filter 28. Because the hydrophobic filter 28 is provided in the exhaust flow path 24, liquids such as urine that flow from the external member through the connection plug body 10 and into the body end 26 do not pass through to the lid end 27, but gases such as air can pass through to the lid end 27. In other words, the exhaust flow path 24 is designed to allow only gases such as air to be discharged from the lid end 27 when the lid 30 is open and not engaged with the intermediate portion 20.
• the lid 30 has an annular groove 33 formed around the seal 32 on the contact surface with the intermediate section 20, and a deodorizing sheet (deodorizing member) 34 is incorporated into this annular groove 33 to deodorize the gas that has reached the lid 30 through the hydrophobic filter 28 of the intermediate section 20. This allows the lid 30 to suppress odors from urine, etc.
• the deodorizing sheet 34 is formed in an annular shape so as to surround the lid end 27 of the exhaust flow path 24 of the intermediate section 20 when the lid 30 is closed. Note that instead of the deodorizing sheet 34, a scented sheet (scented member) containing a fragrance may be incorporated into the groove 33.
• the middle part 20 is open, i.e., the middle part 20 is open relative to the connection plug main body part 10, but the lid part 30 is closed relative to the middle part 20, as shown in FIG. 4.
• the medical instrument cap 100 of this embodiment comprises a connection plug main body 10 formed so as to be connectable to an external member, an intermediate portion 20 provided on the connection plug main body 10 so as to be swingable by a first hinge portion 21 and formed so as to be engageable with the connection plug main body 10, and a lid portion 30 provided on the intermediate portion 20 so as to be swingable by a second hinge portion 31 and formed so as to be engageable with the intermediate portion 20.
• connection plug main body 10 has a urine drainage flow path 14 formed therethrough that runs from the base end 12 for fluid connection to an external member to the opposite tip end 13, and the intermediate portion 20 has an exhaust flow path 24 formed therethrough that runs from the main body side end 26 which fits into the tip end 13 of the connection plug main body 10 for fluid connection to the external member to the opposite lid side end 27, and a hydrophobic filter 28 is provided within the exhaust flow path 24 which allows gas to pass but not liquid to pass through.
• the medical device cap 200 has a check valve 17 provided in the connection plug body 10, and a magnet 29 and iron plates (iron members) 16, 36 for closing the connection plug body 10, the middle section 20, and the lid section 30.
• the iron plate 36 of the lid 30 is fitted into the groove 33, and the deodorizing sheet 34 is fitted onto the iron plate 36.
• the deodorizing sheet 34 is positioned between the magnet 29 of the middle part 20 and the iron plate 36 of the lid 30.
• the medical instrument cap 200 has a magnet 29 built into the middle section 20, an iron plate 16 built into the connection plug body 10, and a magnet 36 built into the lid section 30. This allows the middle section 20 and the lid section 30 to be closed semi-automatically by the magnetic force of the magnet 29, making it easy to operate even for users with impaired hands.
• a magnet 29 is incorporated into the intermediate portion 20
• an iron plate 16 is incorporated into the connection plug body portion 10
• an iron plate 36 is incorporated into the lid portion 30, but this is not limited to this.
• a magnet may be incorporated into the connection plug body portion and the lid portion, an iron plate may be incorporated into the intermediate portion, or magnets may be incorporated into all of the connection plug body portion, intermediate portion, and lid portion.
