Description

[Detailed description of the invention] [Industrial application field] This invention is a test of an automatic urine test device that can quickly and accurately perform a huge amount of urine tests in mass screenings and the like without manual intervention. The present invention relates to a paper supply device.

(Prior art)

As is well known, urinalysis tests the physical and chemical properties of urine, and specifically includes physical quantities such as urine specific gravity, turbidity, color tone, pH, urine glucose, lactose,
Sugars such as fructose galactose, uric acid, amino acids, proteins,
It tests chemical components such as occult blood, urea, bilirubin, alcohol, and salts using test paper or other means.

By the way, in recent years, while the automation of clinical tests is rapidly progressing, the urine test in the group screening of school children, adults, women, elderly people, etc. is still being processed by many humans at present.

One possible cause of this automation delay is:
First, the number of samples at one time is enormous, from several thousand to tens of thousands, secondly, the operation is only performed during mass screening, and the operating efficiency of the machine is extremely low. Fourth, the reason is that the dedicated device cannot be amortized with only the inspection fee, and fourthly, the maintenance of the device becomes difficult if the inspection interval is long.

However, on the other hand, looking at the actual situation of urinalysis at the time of examination, first, it requires a huge amount of manpower and cost for sample reception and examination work, and moreover, it takes many days for test results to appear. Secondly, a group checkup other than the daily checkup operation will force the test workers to overwork, thirdly, the number of checkups at one time due to manual labor is limited, fourthly, Variations due to individual differences in test results even within the same laboratory, fifth, variations between facilities in test results, and sixth, doctor reports due to slower reporting of test results. There are many problems such as that the guidance will be mailed later, and the development of a fully automatic urinalysis apparatus that can solve all of these problems is strongly desired at present.

In order to respond to such a request, several types of fully automatic urine testing devices have already been proposed.However, these conventional fully automatic urine testing devices are of a type in which test sheets are immersed in urine one by one, Alternatively, a required amount of urine is aspirated with a pipette and then urine is dropped on a test paper, and any of these methods is adopted. Maximum number of samples processed per hour is about 20 for 8 items
The number of samples is very small, and the configuration is completely unsuitable for the mass screening.In addition, if this conventional device is to be applied to the mass screening, a plurality of the same model must be installed. However, there is a problem that the equipment cost is extremely high in total, and the actual situation is that the demand has not been sufficiently satisfied.

Therefore, the present applicant has previously proposed an automatic urine test apparatus shown in FIG. 6 in order to eliminate such a conventional problem.

The automatic urine testing apparatus includes a container transfer device 1 for holding and transferring five urine collection containers 10 in a row containing collected urine at predetermined intervals and transferring the urine collection containers 10, and the urine collection container provided in parallel with the container transfer device 1. It comprises a stick transfer device 2 for transferring the test paper sticks 5 corresponding to ten pieces, and a clamp device 3 for gripping the test paper sticks 5.

The container transfer device 1 is constituted by a known endless belt body, and the urine collection container 10 held so as not to fall off the endless belt body is sequentially transferred to the sampling position b at a predetermined intermittent timing.

The stick transfer device 2 is composed of an endless belt, and the endless belt has five test paper sticks 5.
And a plurality of urine suction holes 21 opened in proximity to the portion where the test paper stick 5 is placed,
Are attached at predetermined intervals.

Although not shown, the urine suction hole 21 sucks urine flowing down from the test paper stick 5 placed at a predetermined position of the tray and discharges the urine into a urine reservoir (not shown). The urine suction hole 21 is connected to a vacuum suction pump.

The clamp device 3 is provided with a plurality of (five in this embodiment) test paper sticks 5 corresponding to the number of the urine collection containers 10,
The test paper stick supply position a is rotated 90 degrees and transferred from the test paper stick supply position a to the sampling position b of the container transfer device 1.
After immersion in the urine in 10, each of these test paper sticks 5
Is controlled so as to be supplied to the stick transfer device 2.

That is, the clamp device 3 is an arm that grips each test paper stick 5 supplied by the test paper stick supply device 4 described later at the test paper stick supply position a.
30, a joint member 31 for holding the arm 30 rotatably in the vertical direction, a support member 32 for holding the joint member 31 rotatably in the horizontal direction, and rotating the arm 30 in the vertical direction. It is composed of an arm drive (not shown) and a joint drive (not shown) for rotating the joint member 31 in the horizontal direction.

Therefore, after the arm 30 grips each test paper stick 5 horizontally at the test paper stick supply position a, the clamp device 3 rotates 90 degrees in the horizontal direction and transfers it to the sampling position b. Is rotated downward by approximately 90 degrees, and each test paper stick 5 held by the arm 30 is immersed in each urine collection container 10 at the sampling position b.

Thereafter, the arm 30 pulls out each test paper stick 5 impregnated with urine from the urine collection container 10 and rotates again by 90 degrees while holding each test paper stick 5 at a required inclination angle to rotate each test paper stick. After the stick 5 is placed on the portion of the tray 20 on which the test paper stick 5 is placed, the gripping state is released, and then the arm 30 is turned 180 degrees to return the arm 30 to its original position, that is, the test paper stick. The test paper stick 5 is transported horizontally to the supply position a, and is continuously transported again according to the above procedure.

[Problems of the prior art]

However, in the above-mentioned automatic urine test apparatus proposed by the present applicant, a urine test at the time of mass screening can be automatically processed without any manual operation, and moreover, one apparatus and one hour -The number of samples processed per eight-item measurement can be at least about 10 times or more that of this type of conventional type, so that the time required for this type of test can be significantly reduced and speeded up. Although the measurement results can be unified easily, the reliability of this kind of inspection accuracy can be greatly improved. Is supplied to the stick transfer device 2, so that the configuration and control of the clamp device 3 become very complicated, cost becomes high, and maintenance becomes complicated. The had.

This invention intends to provide a test paper supply device for an automatic urine test apparatus that can reliably supply a test paper supply for the automatic urine test apparatus proposed earlier by the present applicant with a simpler configuration. is there.

[Configuration to solve the problem]

In order to achieve the above object, in the present invention, the device has a mount wound in a roll shape, and a stick supply unit for supplying a test paper on a stick to the front side of the mount, The test paper supply device of the automatic urine test device formed with an adhesive layer on the back side of the test paper is a technical premise, and the lower surface of the stick supply means and the hole of the test paper supply hole A groove is formed on both sides, and a mount molded body having a convex portion fitted with the groove is provided below the mount.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the accompanying drawings.

As shown in FIG. 1, the test paper supply device of the automatic urine test apparatus according to this embodiment is a container transporter that holds five urine collection containers 10 in a row containing collected urine at predetermined intervals and transfers them. Test papers (hereinafter referred to as test paper sticks) 5 provided in parallel with the apparatus 1 and corresponding to the number of the urine collection containers 10 described above.
Is configured to be transported.

As described earlier in the present application, the container transfer device 1 is configured by a known endless belt body, and the urine collection container 10 held so as not to fall off the endless belt body is provided at a predetermined intermittent timing. It is sequentially transferred to a sampling position (not shown).

On the other hand, the test paper supply device includes a mount 20 wound in a roll shape, a stick supply device 21 for supplying the test paper stick 5 to the front side of the mount 20, and a test paper stick 5.
Cutter 22 that cuts the mount 20 supplied with
And is composed of

The backing paper 20 is made of a mesh material, and one end wound in a roll shape is provided with a stick feeding device 21 as shown in FIG.
The test paper stick 5 is configured to be pulled out horizontally to the side, and is attached to the back side of the test paper stick 5 as shown in FIG. An agent layer 23 is formed. Note that a test paper section 24 is provided on the upper surface of the adhesive layer 23.

The stick supply device 21 has five inverted concave holes formed in the main body thereof, and the required number of test paper sticks 5 are stored in the inverted concave holes in a stacked state. Of course, when the lowermost test paper stick 5 is attached to the mount 20, the adhesive layer 23 of the test paper stick 5 above the lowermost test paper stick 5 is peeled off. It is configured not to adhere to the test paper section 24 via paper or the like. Therefore, the release paper is configured to be removed immediately before the test paper stick 5 comes to the lowermost layer.

The main body of the stick supply device 21 configured as described above is moved up and down by an elevating device (not shown), and the test paper stick 5 in the lowermost layer is pressed onto the surface of the mount 20 and adhered thereto.

At this time, grooves 25 are formed on the lower surface of the stick transfer device 2 on both sides of the hole to which the test paper stick 5 is supplied, as shown in FIG. Since the mount body 27 having the convex portion 26 that fits into the groove 25 formed in the stick transfer device 2 is disposed below the mount 20, the test paper stick 5 is pressed against the mount 20. At this time, as shown in FIG. 5, since dam portions are formed on both sides of the test paper stick 5, the urine of another person does not interfere with each other, and cross contamination can be effectively prevented.

After the test paper stick 5 is stuck to the mount 20 and the dam portions are formed on both sides in this way, the mount 20 is sent downstream by a predetermined size and cut by the cutter 22. Is transferred to the urine discharge position further downstream,
At this position, the urine is supplied from the pipette device P that has suctioned a required amount of urine from the urine collection container 10.

At this time, since the mount 20 is formed in a mesh shape as described above, urine flowing down on the mount 20
Is sucked by a vacuum suction pump (not shown) provided on the lower surface of the urine, and urine is discharged into the urine reservoir.

The pipetting device P is for sucking urine from the urine collection containers 10 arranged in a line, for example, and supplying the urine to the test paper sticks 5 arranged on the mount 20. Except for the configuration in which the direction can be rotated by 90 degrees, the other configuration is the same as that of a known pipette device, and a detailed description thereof is omitted here.

The test paper stick 5 is composed of, for example, seven types of test paper pieces impregnated with reagents corresponding to various urine tests and one test blank test paper piece in one row.
Used for urinalysis of humans. The test blank test strip is used to determine whether urine has been reliably supplied from the urine collection container 10 or not.

Although not shown, a detector for performing colorimetric quantitative measurement of the urine component impregnated in the test paper stick 5 is disposed downstream of the stick supply device, and a light source that appropriately varies a wavelength depending on an object to be measured. Irradiates the test paper sticks 5 from each other, receives the reflected light from each test paper stick 5 with a light receiving element (not shown), and measures the absorbance. The principle is the same as that of a known optical colorimeter. The same is true. still,
When measuring the turbidity of urine, one test paper stick 5
Is used for turbidity comparison, and light of a predetermined wavelength is reflected on the test paper stick 5, and the turbidity can be obtained from a change in the intensity of the received light. Of course, in order to avoid the influence of urine color, light having a wavelength not absorbed by urine may be selected and measured with a filter or the like.

The measurement of the color tone of urine is performed using the test strip for the test blank, and a light source having a spectroscope is irradiated with light of a specific wavelength to reflect the light. The coefficients can be determined. Further, if the wavelength of the light from the light source can be continuously varied, an absorption spectrum of urine can be obtained.

The automatic urine test apparatus according to the present embodiment is provided with means for determining whether urine has reliably adhered to each test strip. This means makes use of the fact that the intensity of the reflected light from each test strip varies depending on whether or not each test strip is wet. If the value is equal to or larger than the value, it is configured to be processed as "routine error".

On the other hand, the urine collection container 10 that has supplied urine to the test paper stick 5 at the sampling position is thereafter transferred to a post-processing position (not shown) by the container transfer device 1 and stocked.

By storing the urine collection container 10 at the post-processing position in this way, the urine determined as “positive”, “false positive”, “false negative” or “routine error” by the automatic urine test apparatus A can be obtained. It can be reexamined later.

In the above embodiment, the case where the number of urine collection containers 10 set in the container transfer device 1 is five in one row has been described as an example. However, in the present invention, urine for precision control is stored in this. By setting the one collected urine collection container for each row to form six per row, it is possible to check the discoloration and deterioration of the test paper stick. Of course, it is also possible to replace one of the urine collection containers 10 set in the container transfer device 1 with that for quality control.

[Effect of the invention]

The test paper supply device of the automatic urine test device according to the present invention is:
With the configuration described above, the test paper supply mechanism can be greatly simplified, and as a result, cost can be greatly reduced, maintenance is easy, and dams are provided on both sides of the test paper stick. Since the portions are formed, there is obtained an effect that urine of another person does not interfere with each other and cross contamination can be effectively prevented.
