An automatic locking valve for safely administering a dose of medication is disclosed. The automatic locking valve comprises a valve housing defined with a space and formed with input and output ports for intaking and discharging the medication, a spool-shaped on/off member having a diameter smallest at the center thereof and being tapered to linearly increase toward upper and lower portions of the on/off member so that the on/off member moves up and down depending on a closed state of the door, and a membrane attached to the space of the valve housing such that the membrane expands toward a lower portion of the space due to an elasticity of the membrane when the tube is blocked. The medication can be safely and accurately administered under a condition of installation with the door closed above the tube.

What is claimed is: 1. An apparatus for automatically administrating dose of medication consists of an automatic operating member, the apparatus comprising: a case (4) divided into three compartments, a medication storage chamber (6) for storing a medication pack, a control chamber (8) equipped an LCD (11), and a driving chamber (12) to control injecting the medication, said driving chamber (12) providing a pressure pump (28) for supplying the medication, and a tube (16) for transferring the medication from the medication pack to a needle (20), said tube (16) extended from inner driving chamber (12) to outer case (4), and a lid (22) having a bar (24) for supporting said tube (16) and a pressure protrusion (26), a ball-loose switch (14) for issuing a command signal via an electric line to inject the medication, said ball-loose switch (14) positioned at a predetermined distance outside of the case (4), an automatic locking valve (51) consisting of a valve housing (52), an input port (60) and an output port (62) for flowing the medication, wherein said valve housing (52) formed three parts of inner cavities and an outer cavity, which are a funnel-shaped inner cavity at top portion, an upside-down funnel-shaped inner cavity at lower portion, a disk-shaped inner cavity at middle portion for connecting between the top and lower inner cavity portions and an upside down Petri-dish shaped outer cavity at bottom portion, an on-off member (54) having a slimmed center (54c), wider diameters at top (54a) and bottom (54b) surface and tapered linearly from center to the top and bottom surface to form a concaved lateral surface, so that said on-off member (54) forming the funnel-shaped upper portion, the upside-down funnel-shaped lower portion, and the disk-shaped neck middle portion for suitably fitting into the inner cavities of said valve housing (52) is pushed down as closing said lid (22) to have a lateral clearance as a flow path of the medication and lifted up to block the lateral clearance as opening said lid (22), a membrane (56) attached around a rim of the upside down Petri-dish shaped bottom portion of said valve housing (52) for providing a cavity (58) below the bottom of said on-off member (54b) as the flow path of the medication, said membrane (56) expanding outward when the tube (16) is blocked by a foreign object, and a sensor (44) for detecting a status of blocking the tube (16) to issue a "high signal" when said membrane (56) is swollen to contact said sensor (44). 2. An apparatus for automatically administrating dose of medication as set forth in claim 1, wherein said on-off member has a convex top surface to be easily pushed down by the lid (22) when the lid (22) is closed. 3. An apparatus for automatically administrating dose of medication as set forth in claim 1, wherein said on-off member (54) has a flat bottom surface to provide said cavity (58) between said membrane (56) as a flow path of the medication. 4. An apparatus for automatically administrating dose of medication as set forth in claim 1, wherein said valve housing (52) forms trapezoidal cross section of a valve mounting seat for circumferentially contacting to the tapered lateral surface of said on-off member (54).
