2. Description of the Related Art In recent years, various biosensors utilizing the specific catalytic action of enzymes have been developed and attempted to be applied to the clinical field, and particularly rapid and accurate measurement is possible. Biosensors have been put to practical use.

For example, in the case of a glucose sensor, where the number of diabetic patients is remarkably increasing, it is a very complicated procedure to measure and manage blood glucose level by centrifuging blood and measuring plasma as in the conventional case. Therefore, a sensor that can measure whole blood has been desired. As a device for realizing such a biosensor, Japanese Patent Laid-Open No. 61-2943 has been disclosed.
The biosensor described in Japanese Patent No. 51 is cited. According to the measurement method using this technology, a dedicated measuring instrument supplies a predetermined voltage to the electrode system of the sensor to measure the current value flowing between the electrodes, and the sample is based on the signal obtained by the measurement. The substrate concentration in the liquid is calculated and the value is displayed on the display of the measuring instrument.

Regarding the form of the biosensor and its measuring device, a biosensor cartridge having a plurality of biosensors set therein as described in JP-A-8-262026 is used to load the measuring device and operate a knob. By doing so, a biosensor dispensing device that can perform multiple measurements has been developed, and the sensor is attached to the mounting port of the measuring device main body for users such as diabetic patients who have many elderly people. At this time, the troublesome aspects have been improved such as accidentally dropping the sensor, inserting the sensor in the reverse direction, and further performing the measurement with the sensor inserted in the reverse direction.

Then, when the slide actuator 306 is activated or pushed to the test position, the biosensors are released from the sensor holding cavities 312 one by one, and thus are placed in the test position. The test end of the biosensor protrudes from the test end 305 of the housing,
The contacts on the sensor are coupled to a microprocessor (not shown) and / or other data processing circuitry on a printed wiring board located in the bivalve shell on top of the outer housing 304. As a result, the data obtained from the sensor can be processed when inserted into the blood to be tested. The processed data can then be displayed on the display unit in the upper case 301 of the device or subsequently stored for supply to other analytical instruments via a data port connector (not shown). it can.

Upon completion of the blood analysis test, slide actuator 306 is moved in the opposite direction toward the rear of the device housing to its standby position. As the slide actuator 306 is returned from its test position, the biosensor is removed from the biosensor dispenser 300 and the biosensor pack 310 is advanced (rotated), resulting in another biosensor being the biosensor pack 310. It can be used for the next blood glucose test to be performed.

The biosensor dispenser further includes a manual button (not shown) located on the rear of the upper clam shell portion of the outer housing 303 adjacent the data port connector (not shown). These buttons are used by the user of the device to enter data into the electrical components on the printed wiring board or to obtain information regarding the tests being performed. If data on the tests carried out were stored in the electrical circuit of the printed wiring board, this data could also be monitored via a data port connector, also attached to the rear of the upper bivalve shell part of the equipment housing. Or to computer equipment.

By using an elastic body such as PDM) or an elastomer, it is possible to make the shape easily compatible with the cartridge case 110 that is the mating material when pressing, and it is possible to improve the sealing property and the adhesiveness.

As described above, the biosensor cartridge according to the first embodiment and the biosensor dispensing apparatus to which the biosensor cartridge is attached have the biosensors stacked in the thickness direction housed in the biosensor cartridge. Since the cartridges are attached to the biosensor dispensing device and taken out one by one, the size and area of the biosensor cartridge can be reduced.
The biosensor dispensing device can be downsized, and moreover, the measurement operation can be continuously performed a plurality of times. In addition, because the biosensor cartridges are stored by stacking them with the biosensors facing in the same direction, there is no need for a mechanism to change the posture or direction when storing the biosensor, and the biosensor is a simple mechanism. Can be sent.

Further, since the biosensor stored in the biosensor cartridge and the storage position of the desiccant are stored in a state of overlapping in the thickness direction of the biosensor cartridge, the biosensor in the biosensor dispensing apparatus is stored. The area occupied by the sensor cartridge can be reduced, and the size can be reduced. Further, since the biosensor cartridge is provided with the biosensor pressing member for pressing the biosensor in the stacking direction from the upper surface to the lower surface inside thereof, it is possible to suppress warpage and floating that occur in the biosensor alone, and to reliably perform the biosensor. Can stick out.

When the biosensor is placed, it is equipped with a biosensor detent part that locks the biosensor, preventing the biosensor from returning to the inside of the measuring device after the measurement and entering the measuring device. The trouble of can be prevented. Further, since the tip portion of the biosensor detent portion is brought into contact with the electrode step portion of the biosensor, it is possible to prevent the individual biosensors from dropping into the inside of the apparatus main body.

Further, since the contact portion of the electrode arm is brought into contact with the sensor electrode portion of the biosensor at the position where the biosensor detent portion is sandwiched, the electrical contact can be surely maintained. Further, since the electrode arm is rotated by operating the biosensor protrusion member, it does not require electric power and can surely connect to the sensor electrode portion of the biosensor. .

(Embodiment 4) The biosensor cartridge according to Embodiment 4 of the present invention and the biosensor dispensing apparatus having the biosensor cartridge attached thereto have ribs formed on the inner wall of the cartridge case to prevent the biosensor from being erroneously loaded.
