Subcutaneous vein access port and medicine injection device having the same

A subcutaneous vein access port comprising:

• a housing formed therein with a receiving portion to which a medicine is supplied;
• a cover membrane disposed at an upper end of the housing and sealing an upper side of the receiving portion;
• a conduit provided to the housing and connected to the receiving portion;
• a light source emitting light such that the light from the light source is discharged outside through the cover membrane;
• a power supply disposed in the housing;
• a substrate disposed in the housing and electrically connecting the power supply to the light source, wherein the power supply is positioned on the substrate;
• a switch disposed under the substrate and comprising a push portion, the switch allowing electricity to be supplied to the light source when the push portion is pressed while allowing electricity supply to the light source to be stopped when the push portion is released;
• and
• an actuator directly contacting the push portion to be selectively pressed to turn the switch on/off,
• wherein the housing comprises a body formed therethrough with a coupling hole to which the conduit is connected;
• and a partition dividing an interior of the body into a first space and a second space,
• wherein the first space is defined above the partition and the second space is defined below the partition,
• the receiving portion is a space defined by the first space and a lower surface of the cover membrane,
• the power supply and the substrate are disposed in the second space,
• wherein the actuator comprises a sealing portion tightly contacting a mounting groove circumferentially formed in a stepped manner at a lower end of the body, and a pressing portion connected to the sealing portion to seal the second space,
• wherein the subcutaneous vein access port further comprises:
• a securing ring being inserted into the mounting groove and pressing the entirety of the sealing portion to secure the actuator to the body;
• a plurality of first coupling holes formed in the mounting groove in a circumferential direction thereof;
• a plurality of second coupling holes formed through the sealing portion to correspond to the first coupling holes;
• a plurality of third coupling holes formed through the securing ring to correspond to the second coupling holes;
• and
• a fastening member driven into the third coupling hole to be coupled to the first coupling hole through the second coupling hole to secure the actuator and the securing ring to the body.
