Description

[Detailed explanation of the device] (a) Industrial application field This device is a measuring device used for measuring urine sugar, for example, and has a storage chamber for test strips used for measurement inside the meter body. This invention relates to a small portable biochemical measuring instrument.

(b) Prior art At present, small portable biochemical measuring devices, such as urine sugar measuring devices, have a chamber containing the test strips (test strips with a drug coated on the tip called stags) used during measurements. Nothing with this exists.

Conventional portable urine sugar measuring devices usually have a microcomputer, a reflective sensor, a battery, etc. inside the device body, which consists of a pair of upper and lower halves, and a stick that is inserted at one end of the device body. It is equipped with a holder to hold it. For measurement, urine is soaked in the drug part of the stick, which is inserted into the holder of the device, light is projected onto the drug part, and urine sugar is measured based on the amount of reflected light.

(c) Problems to be solved by the invention As mentioned above, the static system is indispensable for measuring urine sugar.

However, conventional measuring instruments are not designed to accommodate the stakes at all. Therefore, the stake is stored in a dedicated stocker such as a bottle that is separate from the measuring instrument. Therefore, although measuring instruments and stakes should originally be stored as a pair, they are stored separately, making their management complicated, especially when carrying measuring instruments. There was a risk that I would be at a disadvantage, such as forgetting my phone.

This invention aims to solve the above-mentioned problems of conventional devices and to provide a portable small-sized biochemical measuring device with a test strip storage chamber that allows the test strip to be stored in the measuring device at all times. purpose.

(d) Means for solving the problem In order to achieve this purpose, the portable small-sized biochemical measuring device of this invention is capable of conducting a test in which the tip of the test paper is clamped at one end of the flat rectangular cylindrical body. Equipped with a paper holding part,
The rectangular cylindrical container has an electronic circuit section for measurement inside the prismatic cylindrical container, and a measurement display section on the surface of the prismatic cylindrical container, wherein the other end of the prismatic cylindrical container has an electronic circuit section for measurement. A cover body having an opening formed by cutting out a portion thereof, a test strip storage chamber provided in the opening of the rectangular cylindrical container body, and an engaging portion for opening and closing the opening of the test strip storage chamber. , an engagement/disengagement receiving piece that is tiltably disposed in the notch of the rectangular cylindrical vessel body and engages and disengages from the engagement portion of the cover body.

(e) Effect In a measuring instrument having such a configuration, the stake is always stored in a storage chamber inside the instrument body.

For measurement, the engagement part of the cover body and the engagement receiving piece are disengaged, the accommodation chamber is opened, the internal stick is taken out, and the tip of this stick is inserted into the holding part to perform the measurement. The stake removal work and measurement work are extremely simple.

(F) Embodiment The drawing shows a specific embodiment of the urinary sugar meter with a test strip storage chamber according to this invention.

The urinary sugar meter 1 has electronic components such as a microcomputer, an IC, and a battery built into the center of a flat rectangular cylindrical body 11. On the surface of the body 11,
A power switch 15, a measurement switch 14, and a measurement value display section 13 are provided.

At one end of the container body 11, a reflection sensor consisting of a light receiving/emitting element disposed inside the container is exposed, and a test strip holding portion 12 is provided for clamping and holding a stake at a position corresponding to the reflection sensor. .

A feature of this invention is that a storage chamber for storing the stake 5 is formed at the other end of the instrument body.

The stake storage chamber has an opening 16 formed by cutting out the end walls of the upper and lower halves of the container body 11, and a test strip storage frame 18 having a rectangular planar shape inside the opening 16.
A packing 19 with a protruding upper part is embedded in the upper peripheral surface of the housing frame.

The cover body 2 that covers the upper opening of the housing frame 18 has a size corresponding to the upper half notch of the container body 11, and has one end attached to the container body (notch piece) via a spring shaft. When installed, it is always energized upward (vertically). Further, at the other end, an engaging part 21 with a bent tip is provided to protrude downward, and a shaft bearing 32 is provided so as to be tiltable in an end wall notch in the lower half of the vessel body 11.
It can be freely engaged with and disengaged from the locking portion 31 of the deployed engagement receiving piece 3.

Further, on the inside (inside the back surface) of the cover body 2, there is provided a grooved presser frame 22 projecting downward, which presses and fits the protruding portion of the gasket 19 when the upper opening of the housing frame 18 is closed. , keeping the containment chamber sealed.

Although the embodiment shows an example in which the cover body 2 and the engagement receiving piece 3 are formed separately, the present invention is not limited to this, and for example, the engagement receiving piece may be formed continuously on the cover body. In this case, a known engagement/disengagement mechanism is provided between the extended protrusion (engagement receiving piece) of the cover body and the lower end of the container body 11. Moreover, the cover body 2 of the example is
Although a structure is shown in which the cover body is fixed to the container body 11 via a spring shaft, it is of course possible to have a structure in which the cover body is detachable from the container body. Furthermore, in implementation, the installation position of the cover body may be changed as appropriate, such as by setting it on the side wall side of the container body.

In a measuring instrument having such a configuration, the storage chamber 1
The stake 5 is always stored at 7 and prepared for measurement.

Now, when measuring, by pressing the cover body 2 downward and tilting the engagement receiving piece 3 outward, the engagement between the cover body and the engagement receiving piece is disengaged, and the storage chamber 17 is opened. be done. Next, the stick 5 in the storage chamber is taken out, and the tip of the stick soaked in urine is inserted and fixed into the holding part of the container body to measure the urine sugar.

Immediately after the removal of the stake 5 is completed, the cover body 2 is pressed downward against the spring. At this time, the engagement part 21 pushes the engagement receiving piece 3 outward and descends, and when the cover body is completely flush with the surface of the container body 11, the engagement part 21 is held in that state and the engagement receiving piece 3
return to the container side, and the engaging part 21 and the locking part 31
engage and fasten. As a result, the accommodating portion is closed, and at the same time, in this state, the gasket 19 of the accommodating frame fits into the holding frame 22 of the cover body, and the accommodating chamber is maintained in an almost completely sealed state, preventing deterioration and deterioration of the stake 5. is prevented.

(g) Effects of the invention In this invention, as described above, a stake storage chamber is formed in the main body of the measuring instrument itself.

According to this invention, the stake is always stored in a storage chamber that is integrally formed in the rectangular cylindrical body of the portable compact biochemical measuring instrument, and unlike conventional methods, the stake is stored separately during measurement. There is no need to prepare a special container. Therefore, with this invention, it is only necessary to manage the number of stakes in the storage room, and the inconvenience of managing both the measuring instrument and the container dedicated to stakes is eliminated. In addition, when carrying a measuring device, you only need to carry the measuring device, and unlike conventional methods, there is no disadvantage such as not being able to carry out measurements because you forget to carry a special container. have
