[0047] A specific space is provided in the interior of the storage part 250 such that a second medicine may be accommodated in the specific space, and the accommodated second medicine is discharged from the storage part 250 by a pressure applied by the storage part 250 to be discharged through the second tube 220.

[0048] The first medicine and the second medicine are not limited, and as an example, the first medicine may be a medicine that requires continuous injection and may be a pain adjusting medicine injected according to the infusion rate, and the second medicine may be a pain adjusting medicine an amount of which corresponds to a dose, which is infused once, according to a preset demand dose amount that is additionally injected when the patient feels pain.

[0049] In the medicine infusing apparatus, the storage part 250 in which the second medicine is stored is generally far away from the patient for control thereof and disposed individually so that it is often difficult to promptly cope with a situation of the patient, and the medicine infusing apparatus according to the present invention includes a first tube 210, a second tube 220, and a storage part 250 in the interior of a compact cover to be conveniently used and controlled even only by connecting the tubes 210 and 220 to a medicine supply unit (not illustrated), and preferably, a member such as a belt is fastened to a fastening part 160 located on one side of the cover 100 such that the medicine infusing apparatus may be conveniently attached to the body of the patient.

[0050] Meanwhile, as illustrated in FIG. 3, flow rage adjusting apparatuses 230 for adjusting the flow rates of the flowing medicines are provided on the passages of the tubes 210 and 220. As illustrated, the flow rate adjusting apparatus 230 includes a glass tube 231 connected to sides of the tube 210 and 220, and a support that facilitates connections of the glass tube 231 and the tube 210 and 220 and surrounds a circumference of the glass tube 231 to support the glass tube 231. By adjusting the inner diameter of the glass tube 231, the flow rates of the medicine flowing through the tubes 210 and 220 may be adjusted.

[0051] A check valve 240 is installed on one side of the storage part 250 of the second tube 220, in detail, in a discharge direction of the second medicine discharged from the storage part 250 so that the medicine introduced into the storage part 250 through an inlet side of the second tube 220 is discharged to an outlet side before it is fully filled in the storage part 250 to prevent the medicine from being injected to the patient and to allow the second medicine to be discharged from the storage part 250 and discharged through the second tube 220 only when a specific pressure is applied to the storage part 250 even after the storage part 250 is fully filled with the second medicine.

[0052] The press part 300 is located on one side of the cover to be movable, and may apply or release a pressure to the storage part 250 located inside the cover 100 through movement thereof. Any means capable of applying a pressure from one side of the cover 100 such that the second medicine accommodated in the storage part 250 may be discharged is sufficient as a configuration of the press part 300.

[0053] In detail, as illustrated in FIGS. 2 and 4, a hinge opening 322 located on one side of the upper cover 110 passes through the upper cover 110 to be coupled to a hinge member 122 located on one side of the interior of the lower cover 120 so that the upper cover 110 may be hinged about the coupling part, and a protruding press member 313 is located on a surface of the press part 300 that is close to the cover 100 so that the press member 300 may apply or release a pressure to the storage part 250 by a hinge movement of the press part 300 through a press window 113 opened on the press part 300 of the cover 100.

[0054] Additionally, a medicine display window 320 formed of a transparent material may be provided on one side of the press part 300 so that the second medicine accommodated in the storage part 250 may be identified through the press window 113.

[0055] Accordingly, the user may promptly discharge and infuse the second medicine with a simple operation of pressing the press part 300 with a hand Meanwhile, when the usage of the second medicine is particular according to the kind of the second medicine or a side effect or a danger is caused by the injection timing, the simple infusion of the second medicine may be dangerous, and the regulation part 400 is provided as a means for regulating the infusion.

[0056] The regulation part 400 is a means that is located on one side of the lower cover 120 and capable of regulating movement of the press part 300 by providing a regulation means capable of regulating movement of the press part 300 in the lower cover 120.

[0057] In detail, the regulation part 400 may include a locking plate 410, a stopping pin 413, and a locking pin 420.

[0058] As illustrated in FIGS. 2, 5, and 6, the locking plate 410 is coupled to be rotatable through the coupling member 411 located around a central axis thereof and a coupling recess 131 located on one side of the lower cover 120, preferably, through snap coupling.

[0059] A seating part 412 having a specific space is provided around the central axis of the locking plate 410, in detail, inside the coupling member 411, a locking pin 420 that is inserted into and extracted from the seating part 412 is provided, the locking pin 420 is fixed not to be rotated, and an elastic member 430 that elastically support the locking pin 420 may be located between the locking pin 420 and the lower cover 120.

[0060] Regulation bosses 415 protruding toward the inside of the seating part 412 may be located at opposite lengthwise ends of the seating part 412, and opposite ends of the locking pin 420 may be located on opposite sides of the regulation bosses 415 as the locking plate 410 is rotated. Further, a through-hole 401 is formed on a lower surface of the seating part 412.

[0061] The stopping pin 413 extends from a side surface of the lower cover 120 of the locking plate 410 toward the lower cover 120, and the stopping pin 413 is located inside the cover after passing through the through-hole 133 formed in the lower cover 120 to be moved as the locking plate 410 is rotated so that an operation of the press part 300 may be regulated by preventing or allowing a hinge movement of the press part 300 as the stopping pin 413 extends from a side surface of the upper cover 110 of the press part 300 toward the upper cover 110 to be coupled to or separated from the stopping part 330 that passed through the upper cover 110.

[0062] The release member 500 includes a release boss 501 located on one side thereof, and an insertion boss 502 located around the release boss 501.

[0063] The locking plate 410 is rotated as the release member 500 is coupled to the regulation part 400 to be rotated.

[0064] Preferably, the release boss 501 is located at a central portion of one side of the release member 500 so that the locking pin 420 is pressed to be moved to the outside of the seating part 412 as the release boss 501 is inserted into the through-hole formed in the seating part of the locking plate 410 when the regulation part 400 of the release member 500 is coupled (see FIG. 8).

[0065] When the regulation part 400 of the release member 500 is coupled, the insertion boss 502 is inserted into a recess located on an opposite side surface of the lower cover 120 of the locking plate 410 so that the locking plate 410 is rotated as the release member 500 is rotated (see FIG. 7).

[0066] Next, an operation of the medicine infusing apparatus according to the present invention will be described.

[0067] As illustrated in FIGS. 1, 7, and 8, the press part 300 is adhered to the upper cover 110, and the first medicine is continuously introduced through the first tube 210 while the movement of the press part 300 is restricted in a state in which the stopping pin 413 is coupled to the stopping part 330. Further, because the storage part 250 continues to be pressed between the press part 300 and the lower cover 120 by the press member 313 located in the press part 300, the second medicine cannot be introduced into the storage part 250 through the second tube 220 to be stored.

[0068] Further, in this state, the locking pin 420 is stopped by the regulation bosses located in the seating part to prevent rotation of the locking plate 410. That is, the press part 250 is prevented from being operated by rotating the locking plate 410 by force by using a hand or another tool.

[0069] In this state, when it is necessary to infuse the second medicine, the release boss 501 passes through the through-hole formed in the seating part by coupling the regulation part 400 to the release member 500 so that the locking pin 420 is separated to the outside of the seating part by pressing the locking pin 420 as illustrated in FIG. 8.

[0070] Accordingly, the locking plate 410 maintained by the locking pin 420 and the regulation bosses is released to be rotated, and the locking plate 410 is rotated as the insertion boss 502 inserted into the recess of the locking plate 410 is moved if the release member 500 is rotated in this state, and accordingly, the stopping pin 413 is moved to be separated from the stopping part 330 and the press part 300 may be hinged upwards and downwards.

[0071] Accordingly, the second medicine is introduced through an inlet side of the second tube 220 to be introduced into and stored in the storage part, and the discharge of the second medicine is prevented by the check valve 240 located on an outlet side of the second tube 220 as described above while the second medicine is stored.

[0072] After it is identified through the medicine display window 320 that the second medicine is fully filled in the storage part 250, a pressure is applied to the storage part 250 by pressing the press part 300 so that the second medicine accommodated in the storage part 250 exceeds a pass pressure of the check valve 240 and is discharged and infused into the patient.

[0073] As described above, an operation of the press part 300 is allowed only by the release member 500 so that the second medicine may be infused. That is, the release member 500 functions as a key.

[0074] Accordingly, because the release member 500 is managed by a medical expert (a doctor or a nurse) after the second medicine is infused, the second medicine may be injected and a lockout interval may be safely managed so that a danger due to a misuse of the second medicine may be prevented.

[0075] As described above, the medicine infusing apparatus of the present invention may be conveniently used even only by connecting the first tube and the second tube to the medicine supply unit because the first tube, the second tube, and the storage part are provided inside the compact tube.

[0076] Further, the second medicine may be promptly discharged and infused through a simple operation of pressing the press part with a hand, and a danger of side effects due to a deficiency of a usage for injection of the second medicine may be effectively prevented.

[0077] Although the preferred embodiments of the present invention have been described, the present invention is not limited to the embodiments. That is, the present invention may be variously changed and corrected by those skilled in the art to which the present invention pertains without departing from the spirit and scope of the claims, and all the modifications and equivalents have to be regarded as pertaining to the scope of the present invention.
