Piercing device and blood inspection device

Disclosed are a measurement device and a puncture device that prevent thermal loss and enable decreased cost in laser units. A laser unit () of a measurement device () is equipped with a lens barrel (), a laser rod () disposed inside the lens barrel (), a flash lamp () which is disposed opposite the laser rod () inside the lens barrel () and in which an inert gas is sealed inside a hard glass tube (), and supports (), 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 (), and which support the circumferential surface of the hard glass tube () in a housing.

Measurement device and puncture device

A blood test device () ensuring successful measurement wherein fingers scarcely slip out from the blood test device and blood never sticks to other sites in the course from the puncture of the patient's skin to the completion of the blood test. This blood test device () comprises a cartridge () in which sensors () pooling blood oozing out from the punctured skin are stored in a layered state, a transport unit transporting a single sensor sheet () from the inside of the cartridge () to the outside, a holder () holding the transported sensor (), a laser emitting unit () puncturing the skin in the state where the sensor () is held by the holder (), and a pump () keeping the inside of the holder () and the inside of the cartridge () under negative pressure.

Blood test device

A blood test device by which the amount of plumped skin at a puncture site for conducting a blood test or collecting blood can be controlled so that a blood component can be accurately measured. The blood test device includes: a housing; an inner tube provided in one side of the housing; a reciprocating unit which reciprocates within the inner tube; a blood collection needle connected to the reciprocating unit; a blood sensor facing to the blood collection needle and being located at the tip of the inner tube; a measurement circuit to which a signal is fed from the blood sensor; and a negative pressure unit driven by the measurement circuit. An outer tube, that is a tube covering the inner tube, has an opening in the tip side of the inner tube, is capable of moving relative to the inner tube, and is provided so as to return to a definite relative position. The negative pressure provider can apply a negative pressure to the inside of the outer tube.

A lancet is pressed against a puncture needle cartridge while fitting a puncture needle loading inlet of the lancet to the axis of a puncture needle on the puncture needle cartridge. In order to facilitate the operation, one of plural puncture needles, arranged in parallel, is tilted up from its initial position at a predetermined angle, and the puncture needle is guided into a puncture needle holding rod of the lancet. Simultaneously, the puncture needle is pressed up to a position where the rear end part of the needle pushes the bottom surface of a puncture needle loading chamber of the puncture needle holding rod, whereby the puncture needle is loaded. When discarding a used puncture needle, the puncture needle is inserted into a lancet guide member of the puncture needle cartridge, whereby the puncture needle is reliably captured to be discarded.

Puncture needle cartridge and lancet for blood collection

A blood test apparatus having a simple constitution whereby stable measurement can be conducted by surely sampling the blood in an amount being small but sufficient for the test without placing too much burden on a patient. When a first skin contact sensor of this apparatus detects the skin, driving of a negative pressure unit is initiated. Thus, the skin rises and comes into contact with a second skin contact sensor. After piercing into the skin, the negative pressure supply is once ceased. Next, the negative pressure is applied again for a definite period of time. Thus, the opening in the skin is broadened, which facilitates the flow out of the blood.

Blood test apparatus and method of controlling the same

A blood test apparatus has a housing, a blood sensor, and a plurality of connectors. The blood sensor has a plurality of connection terminals that are electrically connected with each electrode of the electrode system; and a reference terminal that serves as a reference. The plurality of connectors are configured to connect to the plurality of connection terminals and the reference terminal of the blood sensor attached at a predetermined position in the blood test apparatus, respectively. And also, relations between the reference terminal and each of the plurality of connection terminals are measured to identify the reference terminal automatically.

Blood test apparatus having blood sensor

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.

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.

Laser perforation device and laser perforation method

A lancet having a slider with a puncture needle holding mechanism at one end thereof, and having a cam ring with a continuous cam groove, rotatable about a support shaft, and with a cam ring claw and an anti-return claw restricting the rotation. The lancet also having a ring spring applying a force to rotate the cam ring, having a rotatable stopper arm holding and releasing the rotation of the cam ring, and having a rotatable ratchet restricting the direction of rotation of the cam ring. A puncture needle unit including a puncture needle body integrally molded with a protrusion fitted to the lancet, a rotation stop rib, a puncture needle, and a puncture needle cap lightly pressed into the puncture needle body.

Lancet for blood collection and puncture needle unit

A blood test apparatus has a housing with an opening, and a plunger that moves back and forth inside the housing, the plunger having a projecting member. A fixing member fixes the plunger, which is provided in the housing. A blood sampling cartridge, in which a blood sensor, a puncturer, and a holder that holds the blood sensor and the puncturer, are integrated. The blood sampling cartridge is removably attached to the opening. The puncturer includes a lancet, one end of which is held by the plunger, and a blood collection needle attached to an other end of the lancet. A measuring circuit measures a signal obtained from the blood sensor to analyze components in the blood.

Blood test apparatus and blood test method

It is intended to provide a means of easily removing a portion of blood bleeding from pierced skin, which has not been taken into a blood sensor but remained on the skin, in a blood test with the use of a blood test apparatus. By using this means, it becomes unnecessary in the blood test to separately prepare a paper sheet, etc. for wiping off. More specifically speaking, a blood test apparatus wherein a blood sensor is provided within a blood sensor unit detachable to the blood test apparatus body and the blood sensor unit has a part to be in contact with the skin in the test and an absorption means. It is favorable that the part to be in contact with the skin in the test serves as the absorption means.
