DETAILED DESCRIPTION OF THE INVENTION

(5) Hereinafter, an embodiment of the present disclosure will be described in more detail with reference to the accompanying drawings.

(6) According to an embodiment of the present disclosure, an infusion pouch set with a built-in injection medicine bottle having a vial function is configured to have,

(7) a discharge port 20 provided at an outlet 12 of a pouch container 10; and

(8) an injection port 30 provided at an inlet 14 of the pouch container 10; and

(9) the injection port 30 includes, an injection needle part 40 configured to have an injection needle 44 provided vertically on an upper part of an injection needle holder 42 which is welded to the inlet 14 of the pouch container 10;

(10) an inner cap 50 having a sealing membrane 52 which is coupled to the injection needle holder 42 of the injection needle part 40, accommodates the injection needle 44 therein, and is punctured by the injection needle 44 when lowered;

(11) an outer cap 60 which is vertically moveable along the same axis as the inner cap 50 and accommodates an injection medicine bottle 70 in an upside down state therein; and

(12) a packing holder 90 which is vertically movably coupled at an upper part of the sealing membrane 52 of the inner cap 50, and a lower part of the packing holder 90 accommodates a packing 80 which hermetically couples an inlet cover 72 with the sealing membrane 52 and has a vertical through-hole 82 at its center.

(13) The sealing membrane 52 formed inside the inner cap 50 so as to cover the inner diameter thereof is configured to have, a protruding part 53 which is convex upward and is concave downward when the packing holder 90 is pressed,

(14) an annular plate part 54, which is provided on an upper surface of the protruding part 53 in an annular plate form, and

(15) a hemispherical protruding part 55 protrudes so as to be inserted into a vertical through-hole 82 of the packing 80 at an inner diameter part of the annular plate part 54.

(16) The packing holder 90 is configured to have a tapered part 96 for receiving the shoulder of the injection medicine bottle 70 provided with a vertical guide 92 having a groove or protruding form perpendicularly disposed on an outer surface thereof to guide an injection to the inner cap 50 at a lower end of a tubular body part 94, which moves vertically with the inner cap 50, and

(17) a bottom plate 98 supported by the annular plate part 54 at the lower end of the tapered part 96 and has a protrusion insertion hole 97.

(18) At an inner cap 50 portion corresponding to the vertical guide 92 having a vertical groove or protrusion form on an outer surface of the tubular body part 94 of the packing holder 90, a movement guide 56 is formed, wherein the movement guide 56 includes a protrusion form or groove formed to the vicinity of an edge of the sealing membrane 52.

(19) The injection needle holder 42 of the injection needle part 40 is configured to have a holder tube 45 which is welded to the inlet 14 of the pouch container 10, a support plate 47 coupled to an upper end of the holder tube 45 for supporting an injection needle head part 46 having an injection needle through-hole 48 through which the injection needle tube penetrates, and a coupling dam 49 protruding at the upper part of the edge of the support plate 47 so as to be coupled with the inner cap 50.

(20) The infusion pouch set with a built-in injection medicine bottle having a vial function according to the present disclosure may have a horizontal ring 57 for supporting a C-shaped clip 100 formed integrally with a lower end of the inner cap 50 which is fixed to the outer diameter of the coupling dam 49 and is located on the inner diameter of the outer cap 60.

(21) The C-shaped clip 100 is configured to wrap the outer circumference of the inner cap 50 between the lower end of the outer cap 60 and the upper part of the horizontal ring 57 and to spread its opening so as to be horizontally separated when it is pulled outwardly. It is preferable that a handle ring protruding toward the opposite side of an opening portion is additionally provided at middle portion of the C-shaped clip 100 so as to be easily separated. However, another form in which a pulling function is performed by a ring, a protrusion or the like may be adopted.

(22) The bottom surface between the coupling dam 49 and the injection needle 44 may be formed with an inclined surface 49a so as to be inclined from the coupling dam 49 downwards toward the perimeter of the injection needle 44, and at the perimeter of the inclined surface 49a and the injection needle 44, an inclined through-hole 49b may be formed.

(23) The holder tube 45 and the injection needle holder 42 of the injection needle part 40 of the present disclosure are hermetically welded to the inlet 14 of the pouch container 10. Since the welding technique itself is a well-known technique, it is described simply as being welded.

(24) The support plate 47 of the injection needle holder 42 and the horizontal ring 57 of the inner cap 50 of the present disclosure are also welded. Although hook-coupling or screw-coupling means can be used, it is preferable to use a welding method for the purpose of providing airtightness when medicine is used.

(25) In the present invention, infusion solution is first filled into the pouch container 10 and then a discharge port and an injection port are formed, and the outlet 12 and inlet 14 are welded to be sealed.

(26) In use, the C-shaped clip 100 is separated to expose the lower end of the inner cap 50 and the horizontal ring 57 by grasping the handle of the C-shaped clip 100 and pulling it toward the opposite side of the open portion. In this case, a space is generated corresponding to the height of the C-clip 100. Therefore, when the outer cap 60 is rotated in a screw rotating manner, the external screw 58 along the inner cover 50 and the internal screw of the outer cap 60 are screw-coupled, and the outer cap 60 is lowered.

(27) When the outer cap 60 is lowered, the injection medicine bottle 70 accommodated inside the outer cap 60 is lowered at the same time. The injection medicine bottle 70 and the inlet cover 72 are sealed to push the packing 80 having a vertical through-hole 82 in its center and the packing 80 tends to rotate the packing holder 90 while pushing. However, the outer surface of the packing holder 90 has a vertical guide 92 which is coupled with a movement guide 56 of the inner diameter part of the inner cap 50 in a protrusion-groove coupled manner so that the vertical guide 92 is lowered vertically. In this case, in the initial coupling with the vertical through-hole 82 and protrusion insertion hole 97 of the bottom plate 98, as shown in FIG. 3, a hemispherical protruding part 55 is inserted so as to be in a protruding state. As a result, the packing holder 90 is lowered vertically while the bottom plate 98 of the packing holder 90 pushes the annular plate part 54 downward to cause the protruding part 52 to start becoming concave. At the same time, the distal end of the injection needle 44 punctures the hemispherical protruding part 55 in a fixed state, and then the injection needle 44 punctures the inlet cap 72 of the injection medicine bottle 70 to form the state shown in FIG. 4. Thus, the medicinal solution in the injection medicine bottle is naturally supplied through the injection needle hole 43 of the injection needle 44, and is mixed with the infusion liquid via the injection needle through-hole 48.

(28) It is a well-known technique to use other infusion needles to discharge to the body's blood vessels through the discharge port 20 of the outlet 12, and the explanation of the discharge is omitted.

(29) In the present invention, when the infusion container cannot be erected vertically while being transported or stored, even if the infusion solution in the infusion container moves to the space between the sealing membrane 52 and the supporting plate 47 through the injection needle hole 43 of the injection needle 44, the bottom surface of the support plate 47 forms an inclined surface 49a, and the lower end of the inclined surface 49a forms an inclined through-hole 49b communicating with the inner part of the infusion container so as to return the infusion liquid to its original position inside the infusion container again without any problems in use and acts to erase the impression of the infusion liquid that seems to flow downwards.
