Abstract: A blood test device using a laser as a puncture member. More specifically, in a blood test device using a laser as a puncture member, the skin can be fixed at a definite position by raising the punctured skin under negative pressure, and thus the skin is brought into close contact with a blood sensor and the laser is focused on the vicinity of the blood sensor face. Thus, it is possible to provide a blood test device of the laser puncture type in which the skin can be surely punctured while giving little pain to a patient.

Abstract: A laser perforation device that has a simple structure and with which pain to a person in skin perforation is reduced. In the device, a laser beam emitted from a laser emitting device is branched into laser beam paths by splitters and mirrors and pierces skin by applying the split beams to the same position on the skin. Since the skin is pierced by a laser beam with a low output, pain to the person can be reduced.

Abstract: A plate on which a channel pattern is formed, which channel pattern includes a first channel into which a buffer agent is injected, and a second channel having, in a portion thereof, a quantification part that has a portion common to the first channel and holds a predetermined amount of a biological sample, the biological sample being injected into the channel including the quantification part, and the plate is rotated at a high speed by a filling unit to fill the buffer agent in the first channel, and thereafter, the second channel is pressurized by a discrimination unit to fill the biological sample in the second channel, and simultaneously, a predetermined amount of the biological sample is added into the buffer agent. Therefore, when performing discrimination of the biological sample, a discrimination result can be obtained accurately in a short time without the necessity of complicated preparation works.

Abstract: It is possible to provide a laser unit which can sting a skin with a small-diameter hole causing a small pain. The laser unit (1) includes: a laser rod (3) which applies a laser beam; a lens (7) which collects a laser beam applied from an irradiation unit; and a laser transmission plate (9) having a mirror portion on the side to which the laser beam comes in and a rough portion having an average surface roughness Ra on the side from which the laser beam goes out. With this configuration, the laser beam which has passed through the laser transmission plate (9) is scattered by the rough portion and the intensity of the laser beam applied to the skin is not concentrated to the center. Moreover, the laser beam generates an impulse wave when passing through the rough portion. That is, the energy is discharged in advance.

Abstract: A laser perforation device that has a simple structure and with which pain to a person in skin perforation is reduced. In the device, a laser beam emitted from a laser emitting device (33) is branched into laser beam paths by splitters (170a, 170b, 170c) and mirrors (171a, 171b, 171c) and pierces skin (13) by applying the split beams to the same position (177) on the skin (13). Since the skin is pierced by a laser beam with a low output, pain to the person can be reduced.

Abstract: A piercing device and a blood inspection device that have increased safety. The piercing device (111) has a piercing button (113) placed on the front surface of a first case (112a), a base (114) being a piecing opening provided projecting from the front surface of the first case (112a), and a laser emission device (115) received in the first case (112a). First safety means (117) prevents emission of a laser beam (115a) to the outside when the first case (112a) and a second case (112b) are superposed on each other. When the base (114) is depressed after the second case (112b) is moved from the superposed state where the second case (112b) is superposed on the first case (112a) to a non-superposed state where the second case (112b) is not, a switch (114b) detects the depression of the base (114) and second safety means (118) to enable depression of the piercing button (113).
