Measurement device and puncture device
View Patent ↗Disclosed are a measurement device and a puncture device that prevent thermal loss and enable decreased cost in laser units. A laser unit ( 200 ) of a measurement device ( 100 ) is equipped with a lens barrel ( 210 ), a laser rod ( 220 ) disposed inside the lens barrel ( 210 ), a flash lamp ( 230 ) which is disposed opposite the laser rod ( 220 ) inside the lens barrel ( 210 ) and in which an inert gas is sealed inside a hard glass tube ( 231 ), and supports ( 241, 242, 243, 244 ), which are made from a material with thermal conductivity of 100 W/(mK) or more, at least parts of which are disposed outside of the lens barrel ( 210 ), and which support the circumferential surface of the hard glass tube ( 231 ) in a housing.
1. A measurement device comprising a laser unit for puncturing, the laser unit including:
a lens-barrel;
a laser rod arranged inside the lens-barrel;
a flash lamp arranged to oppose the laser rod inside the lens-barrel and having an inert gas sealed in a hard glass tube; and
a support member at least a portion of which is arranged outside the lens-barrel and which supports an outer circumferential surface of the hard glass tube on a unit case and is made of a material having a thermal conductivity of 100 W/(m·K) or higher.
2. The measurement device according to claim 1 , wherein the support member supports the outer circumferential surface of the hard glass tube in an outer circumference direction of an electrode inside the hard glass tube.
3. The measurement device according to claim 1 , wherein the support members is arranged to block an opening of the lens-barrel.
4. The measurement device according to claim 1 , wherein the support member is a pair of support media arranged such that openings at both ends of the lens-barrel are blocked.
5. The measurement device according to claim 1 , wherein the support member is energized toward an opening of the lens-barrel.
6. The measurement device according to claim 1 , wherein the support member includes a thermal diffusion section extending in a direction of the outer circumferential surface of the lens-barrel.
7. The measurement device according to claim 1 , wherein the support member includes a heat transfer member to dissipate heat in the lens-barrel.
8. The measurement device according to claim 1 , wherein the unit case has a vent hole provided in an outer circumference direction of the lens-barrel.
9. The measurement device according to claim 1 , wherein a surface of the support member facing an opening of the lens-barrel is planished.
10. The measurement device according to claim 1 , wherein the support member is formed with a metallic material.
11. The measurement device according to claim 1 , wherein the support member is made of aluminum or an aluminum alloy.
12. A puncturing device that punctures a skin by radiating the skin with laser light by a laser unit, the laser unit comprising:
a lens-barrel;
a laser rod arranged inside the lens-barrel;
a flash lamp arranged to oppose the laser rod inside the lens-barrel and having an inert gas sealed in a hard glass tube; and
a support member at least a portion of which is arranged outside the lens-barrel and which supports an outer circumferential surface of the hard glass tube on a unit case and is made of a material having a thermal conductivity of 100 W/(m·K) or higher.
13. The puncturing device according to claim 12 , wherein the support member supports the outer circumferential surface of the hard glass tube in an outer circumference direction of an electrode inside the hard glass tube.
14. The puncturing device according to claim 12 , wherein the support member is arranged to block an opening of the lens-barrel.
15. The puncturing device according to claim 12 , wherein the support member is a pair of support media arranged such that openings at both ends of the lens-barrel are blocked.
16. The puncturing device according to claim 12 , wherein the support member is energized toward an opening of the lens-barrel.
17. The puncturing device according to claim 12 , wherein the support member includes a thermal diffusion section extending in a direction of the outer circumferential surface of the lens-barrel.
18. The puncturing device according to claim 12 , wherein the support member includes a heat transfer member to dissipate heat in the lens-barrel.
19. The puncturing device according to claim 12 , wherein the unit case has a vent hole provided in an outer circumference direction of the lens-barrel.
20. The puncturing device according to claim 12 , wherein a surface of the support member facing an opening of the lens-barrel is planished.
21. The puncturing device according to claim 12 , wherein the support member is formed of a metallic material.
22. The puncturing device according to claim 12 , wherein the support member is made of aluminum or an aluminum alloy.
