Abstract

PURPOSE:To make sanitary inspection of urine and to improve the convenience of an instrument by providing a rolled test paper piece into a test paper piece cassette, drawing out said test paper piece automatically by every fixed length, dropping the urine from a urine drawing pipe thereto and effecting reaction. CONSTITUTION:The long-sized rolled test paper piece 31 disposed with many sheets of the test paper 35 at suitable spaced intervals is housed into the test paper pieces cassette 3. The test paper piece 31 is drawn out by a test paper piece feeding means 4 and a moistureproof film 36 of the test paper piece 31 is stripped and is taken up on a take-up roller 38. The test paper 35 of the test paper piece 31 is fed to an inspection section of a mounting base plate 33. The test paper 35 is supplied at every fixed length so as to meet the corresponding positions of a urine inspecting sensor 7 and a urine nozzle 55. The urine is automatically fed through the urine drawing pipe 51 to the urine nozzle 55 which drops the urine onto the test paper 35 to effect coloration reaction. The coloration is optically detected by the sensor 7 and the urinary sugar value is measured. Since the test paper piece is automatically fed to the inspection section at every fixed length, the sanitary and quick inspection is permitted.

Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention is an automatic urine test device that automatically measures, for example, urine, occult blood, urinary tract, etc. The present invention relates to an automatic urine testing device that automatically sends test strips of fixed length to a testing section.

(b) Prior art At present, for example, a urine sugar measuring device for measuring urine sugar uses a test paper piece (referred to as a test stick, which is a synthetic resin sheet with a test paper impregnated with a reagent attached to the top surface). There is no automatic transport to the urine testing department.

Conventional urine sugar needles have a control section equipped with a CPU (central processing unit), etc. inside the meter body, and an inspection section equipped with a light emitting element (light emitting diode) and a light receiving element (phototransistor). This structure includes an external test paper introduction opening into which a test paper portion of a test paper strip is inserted and arranged in correspondence with the test section.

When measuring urine sugar, one test stick is taken out of the stick box that stores many test strips, urine is dripped onto the test paper, and after a predetermined period of time, the test stick is inserted into the stick box of the meter body. 4 pieces i51'10
Insert and place it from the section to the position corresponding to the inspection section. Then, the light emitting element is caused to emit light, the reflected light is received by the light receiving element, and the urine sugar value is detected based on the amount of reaction light caused by the color reaction.

(C) Problems to be Solved by the Invention In conventional urine sugar needles, the meter body and the stick box that houses the test stick are separate bodies. Therefore,
During testing, it is necessary to take out the test stains one by one from the stick box, and this taking out work is time-consuming, and there is a disadvantage in that the testing work takes a long time, especially in mass medical examinations.

In addition, the test subject must apply urine to the test stick that has been taken out, grasp the urine-stained test stick with fingers, and insert it into the instrument testing section, which is extremely unhygienic. There were many disadvantages, such as the need to wash hands and the testing section of the instrument body after each test.

This invention solves the above-mentioned problems by incorporating a test strip cassette into the urine test main body, and automatically pulling out the long test strips stored in the cassette in fixed lengths for testing. An object of the present invention is to provide an automatic urine test device that is sanitary to transport to the department and has improved convenience in measurement.

(d) Means and operation for solving the problem In order to achieve this object, the automatic urine testing device of the present invention has the following configuration.

The automatic urine testing device is equipped with a urine collection introduction section, a test strip cassette that stores rolled test strips inside and is equipped with a test strip take-out section at the appropriate location, and a test strip take-out section of the test strip cassette. A urine collection means comprising a test strip feeding means, a urine test sensor disposed corresponding to the test strip take-out section, a urine collection body having a urine collection pipe connected to the urine collection introduction section communicating with a tip nozzle, and the urine collection means. and a conveyance means for reciprocating the urine collection body between the test paper portion of the sent-out test paper piece and the excess pressure removal means.

In the urine pulse testing device having such a configuration, a test strip cassette is replaceably arranged inside the urine testing main body. The test paper strip cassette stores long test paper strips in which a large number of test strips are arranged at appropriate intervals and are wound into a roll.

Now, when measuring urine sugar, the test strip feeding means automatically sends out a fixed length of test strips from the cassette, and the test strips are lined up in series at a fixed interval to positions corresponding to the urine test sensor and the nozzle of the urine sample. do. Here, for example, a blank value of the test strip located at the most extreme position, that is, the test strip located corresponding to the urine test sensor, is read. Then, the urine in the urine collection pipe is dripped onto the test paper following the most advanced test paper, that is, the test paper located corresponding to the nozzle of the urine collection body, via the urine collection body and the nozzle.

Next, the test paper strip is automatically fed out a predetermined length by the test paper strip feeding means, so that the test paper impregnated with urine is positioned corresponding to the urine measurement sensor. Here, light is projected onto the test paper from the light-emitting element of the measurement sensor, and the light-receiving element receives the amount of reflected light, reads the colored reaction light, and detects the urine sugar value etc. by comparing it with a blank value. At this time, at the same time, the urine collection body is moved backward from the test paper surface of the test strip and transferred to the surplus urine removal means side by the magnetic transport means, and the surplus pressure in the urine collection pipe is transferred through the nozzle of the urine collection body to the surplus pressure removal means. After being discharged to the (excess pressure removal pipe), the urine sample returns to its original position (on the surface of the test paper), and the nozzle is placed in a corresponding position on the test paper that will be sent out next.
