Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the present invention provides a novel cap, which comprises a first cylindrical member 10, a second cylindrical member 20 and a gas-permeable, water-impermeable membrane 40.
The first cylindrical member 10 has a first end and a second end, and both the first end and the second end of the first cylindrical member 10 are open ends.
The second cylindrical member 20 has a first end and a second end, the first end of the second cylindrical member 20 is an open end, the second end of the second cylindrical member 20 is connected to the outer wall of the first cylindrical member 10 by an annular connecting portion 30, and the annular connecting portion 30 is disposed along the radial direction of the first cylindrical member 10.
The membrane 40 covers the second end of the first cylindrical member 10.
The first cylindrical member 10 and the second cylindrical member 20 are coaxially arranged.
The first end of the first tubular member 10 is positioned within the second tubular member 20 such that if the medicament overflows from the first tubular member 10, the overflowing medicament will remain in the area between the first tubular member 10 and the second tubular member 20.
The surface of the first end of the annular connecting part 30, which is far away from the first cylindrical part 10, is provided with an annular bulge 50, the annular bulge 50 and the first cylindrical part 10 are coaxially arranged, the film 40 is circular, and the circumferential edge of the film 40 is connected with the inner circumferential wall of the annular bulge 50, so that the film 40 is firmly fixed.
The outer peripheral wall of the second cylindrical member 20 is provided with a radial convex ring 60, and the outer peripheral wall of the radial convex ring 60 is provided with a plurality of arc-shaped protrusions 61 which are distributed along the circumferential direction of the radial convex ring 60 at intervals, so that the novel cap can be pulled easily through the radial convex ring 60 and the arc-shaped protrusions 61.
The utility model also provides an infusion apparatus, it include the drip chamber with novel cap, be provided with exhaust apparatus in the drip chamber, the last exhaust passage who is linked together with the bottom liquid outlet of drip chamber that is provided with of exhaust apparatus, first tube-shaped part 10 of novel cap insert in exhaust passage, the outer wall of first tube-shaped part 10 and exhaust apparatus's exhaust passage's inner wall tight fit, 20 covers of second tube-shaped part of novel cap are put on exhaust apparatus, exhaust apparatus's tip offsets with annular connecting portion 30, and like this, novel cap covers exhaust apparatus's exhaust passage, through the ventilative waterproof characteristic of film 40, can make exhaust passage can only exhaust and can't permeate water.
