Abstract
The present invention relates to a needle unit for injecting liquids such as medicine or tattooing pigment spread to a skin, into the skin, and a dermatological liquid injection apparatus using the same. The present invention includes a body unit including a driving device, a cam member rotated by the driving device, and a connecting member reciprocally driven by the cam member; a needle unit detachably mounted to a front end of the body unit; and a rubber member installed to the needle unit, for blocking blood and liquid mixture which are discharged from a skin of a patient and flow into the needle unit, from flowing to the body unit during a medical procedure.
Claims16
A liquid injection apparatus comprising:
- a body unit comprising a driving device, a cam member rotated by the driving device, and a connecting member reciprocally driven by the cam member;
- a needle unit detachably mounted to a front end of the body unit;
- and
- a rubber member installed to the needle unit, for blocking blood and liquid mixture which are discharged from a skin of a patient and flow into the needle unit, from flowing to the body unit during a medical procedure,
- wherein the needle unit comprises:
- a needle support comprising a plurality of needles and a plurality of liquid discharge holes for ejecting liquid;
- a liquid reservoir coupled with the needle support in one opening and containing liquid;
- a movable rod connected to the liquid reservoir with one side and detachably connected to the connecting member with the other end;
- and
- a cap unit for surrounding the needle support and the liquid reservoir and comprising a support unit which the movable rod penetrates,
- wherein the liquid reservoir forms a first liquid injection hole of a long hole shape in one side, and the cap unit forms a second liquid injection hole in one circumference surface.
A liquid injection apparatus comprising:
- a body unit comprising a driving device, a cam member rotated by the driving device, and a connecting member reciprocally driven by the cam member;
- a needle unit detachably mounted to a front end of the body unit;
- and
- a rubber member installed to the needle unit, for blocking blood and liquid mixture which are discharged from a skin of a patient and flow into the needle unit, from flowing to the body unit during a medical procedure,
- wherein the needle unit comprises:
- a needle support comprising a needle;
- a movable rod connected to the needle support with one side and detachably connected to the connecting member with the other side;
- a cap unit comprising the needle support inside to move and containing the injected liquid;
- and
- a guide tip coupled to a front end of the cap unit for guiding the needle to reciprocally move to outside, and comprising a discharge hole for discharging the liquid,
- wherein the rubber member is disposed between the movable rod, tightly coupled to the support unit of the cap unit with one side, and tightly coupled to part of the movable rod with the other side,
- wherein the guide tip includes a first liquid injection groove formed in part of the rear side, and the cap unit includes a second liquid injection groove.
A needle unit of a dermatological liquid injection apparatus for injecting liquid such as medicine or tattooing pigment spread onto a skin, into the skin, comprising:
- a needle support comprising a plurality of needles and a plurality of liquid discharge holes for ejecting liquid;
- a liquid reservoir coupled with the needle support in one opening and containing liquid;
- a movable rod connected to the liquid reservoir with one side and detachably connected to one end of a driving unit in the liquid injection apparatus with the other side;
- and
- a cap unit for surrounding the needle support and the liquid reservoir and comprising a support unit the movable rod penetrates,
- wherein the liquid reservoir forms a first liquid injection hole of a long hole shape on one side, and the cap unit forms a second liquid injection hole in one circumference surface.
A needle unit of a dermatological liquid injection apparatus for injecting liquid such as medicine or tattooing pigment spread onto a skin, into the skin, comprising:
- a needle support comprising a needle;
- a movable rod connected to the needle support with one side and detachably connected to one end of a driving unit in the liquid injection apparatus with the other side;
- a cap unit accommodating the needle support to move and containing the injected liquid;
- and
- a guide tip coupled to a front end of the cap unit for guiding the needle to reciprocally move to outside, and comprising a discharge hole for discharging the liquid,
- wherein the guide tip includes a first liquid injection groove formed in part of the rear side, and the cap unit includes a second liquid injection groove.
