Abstract

PURPOSE:To provide a method and device for foreseeing AIDS (Acquired Immunodeficiency Syndromes). CONSTITUTION:A sampled blood is checked by applying the sample to rolled paper carrying an HIV reagent applied to the paper. At the time of applying the sample, a hollow needle 4 is put on the connecting tube 3 of a pipette 2 housed in a cylindrical container 1 and one end of the rolled paper 5 housed in the container 1 and carrying the HIV reagent is pulled out from the groove 8 of the container. Then the sampled blood 25 is applied to the paper 5 by means of the needle 4. It is contrived to disuse the used needle 4 and used part of the paper 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for predicting AIDS (acquired immunodeficiency syndrome).

[0002]

2. Description of the Related Art A person who has acquired immunodeficiency syndrome (AIDS) infection in Japan is 1991 according to a statement by the Ministry of Health and Welfare.
At the end of the year, the cumulative total was 1955 and the number of patients was 453. It is unknown how many potential patients there are.
It is said to be everyone. The disease is a disease in which lymphocytes are committed by the AIDS virus (HIV), making it easier for any weak pathogen to become infected. There is a reverse enzyme inhibitor such as AZT or DDI as a therapeutic drug for this disease, but it does not cure the disease fundamentally, but it is only a drug that suppresses the onset of the infected person. When these drugs are administered for a long time, not only the AIDS virus is ineffective but also side effects such as anemia occur. MCDS-71, α-INF, etc. developed in Japan were all for suppressing the onset of infected persons. AIDS virus (HIV) is transmitted through blood and body fluids.

[0003]

The present invention is based on this HIV
It is an object of the present invention to provide means for predicting infection, and as a result of the prediction, provide means for preventing non-infected persons from being infected with the AIDS virus from those infected with the AIDS virus.

[0005]

The blood of one person collected by the hollow needle of the cylindrical container for predictive examination is applied to the HIV reagent applied to the paper to check the HIV. Discard the checked hollow needle and paper, and collect blood of the other person using a new hollow needle and apply it to the HIV reagent of the new paper to check HIV. Use the skin attached to the cylindrical container. Attach multiple blood collection needles apart from each other,
Using a hollow card whose surface is coated with a reagent, the blood of one person's site injured by one blood collecting needle is applied to the HIV reagent of one site partitioned by the hollow card to check AIDS. The blood of the other person's site injured by another new blood collection needle is applied to the HIV reagent of the other site partitioned by the hollow card to check for AIDS. Use the skin contained in the hollow card.

EXAMPLE The present invention comprises means (1) for detecting the prevalence of AIDS, means (2) for detecting AIDS and measuring positive and negative, and means (3) for preventing AIDS infection. A method and apparatus for sequentially performing the steps are provided. That is, FIG.
2 is a perspective view and an exploded perspective view of an embodiment of the present invention, FIG. 3 is a vertical side view of FIG. 1, and FIGS. 4 and 5 are perspective views and exploded perspective views and vertical side views of other embodiments. It is a figure. In FIGS. 1, 2 and 3, reference numeral 1 denotes a cylindrical container to which a tip cylinder 1a is screwed, and a blood sampling dropper 2 is freely stored inside the cylindrical container 1. 3 is a connection pipe for the tapered hollow needle 4 of the dropper 2 and 5 is a roll paper with an HIV positive / negative test reagent (hereinafter referred to as HIV reagent) manufactured by Agen Bio Medical Co., Australia, which is loosely wound around the connection pipe 3. The roll paper 5 with the HIV reagent is provided with slits 6 in the form of a strip, and a groove 8 is formed by cutting the end of a sheet piece 7 partitioned by the slits 6 into the container 1.
It can be pulled out further and separated one by one. Reference numeral 9 denotes a cap applied to the rear end of the container 1, and a hollow needle mount 10 holding several replacement hollow needles 4 is attached to the rear end of the container 1 by the cap to attach the hollow needle mount 10 to the container 1. The hollow needle 4 is housed inside the container 1 by means such as screwing the cap 9 into the end portion and fitting. On the surface of the roll paper 5 with HIV reagent, blood 2 collected by the hollow needle 4
The HIV reagent 23 which is detected by printing 5 is applied, and the blood is transferred from the hollow needle 4 to the HIV reagent 23 and the applied blood 25 is visually observed to see if it coagulates or flows. A negative HIV carrier can be tested. The hollow needle 4 used once is discarded. Reference numeral 11 denotes a skin that is removably housed inside the tip of the container 1.

When the cylindrical container 1 has elasticity, the center of the cylindrical container 1 is pressed with fingers to dent the dropper 2 to expel the air from the dropper 2 and the tip of the hollow needle 4. By inserting the portion into a blood vessel and stopping the pressing of the cylindrical container 1 to restore it to the original cylindrical container, the dropper 2 automatically returns to the original state. However, when the cylindrical container 1 is made of a hard material, the base of the cylindrical container 1 is attached to the base of the elastic pressing pin 12, and the end of the pressing pin 12 is opened in the peripheral wall of the cylindrical container 1. Cylindrical container 1 from 13
The inner surface of the dropper 2 accommodated in the cylindrical container 1 is pressed by the tip of the pressing pin 12 to make it concave. Reference numeral 14 denotes a U-shaped elastic plate that is provided between the outer surface of the dropper 2 and the inner surface of the cylindrical container 1, and the U-shaped elastic plate 14 is used to insert the dropper 2 of the dropper 2 at the tip of the pressing pin 12. When the outer peripheral surface is pressed and the pressing of the pressing pin 12 is stopped, the U-shaped elastic plate 14 returns to its original state, and blood is sucked from the tip of the hollow needle 4 toward the dropper 2.

In FIGS. 4 and 5, reference numeral 20 denotes a blood collecting needle 21 in each of the cavities 26 provided with openings toward the outside of the four corners.
Is a hollow card having a skin 22 accommodated therein. HIV reagent 23, which is detected by applying blood 25 on the front surface of hollow card 20, has several parallel partition lines 24.
It is coated inside. At the four corners of the hollow card 20, the bases of a plurality of blood collection needles 21 are axially fixed, respectively. When not in use, the tip of the blood collection needle 21 is tilted inward so as not to project outside the card 20 and stored. ing. At the time of use, one of the blood collecting needles 21 is raised to the outside so as to project outward from the outer peripheral edge of the hollow card 20, and the skin of the earlobe or the like is broken at the tip of the blood collecting needle 21 to cause bleeding. Blood 2
5 is smeared in one compartment of the HIV reagent 23 applied in the partition line 24, and HIV positive / negative is tested.
Next, the skin 22 is taken out from the hollow chamber 26 of the hollow card 20 and used.

[0009]

As described above, the first effect of the present invention is that the blood of an individual who has collected blood is never transferred to another person. That is, the blood collected from the hollow needle is applied to the HIV reagent paper to check for AIDS infection. When the inspection is completed, the hollow needle and the reagent paper coated with blood are discarded. Similarly, the blood at the site of the wound that was injured with a blood sampling needle is applied to HIV reagent paper to test for positive / negative of AIDS infection. After the test, the used blood collection needle and the blood-coated HIV reagent paper are discarded. As described above, it is possible to eliminate the troublesomeness of having an AIDS-infected person to be examined at a specialized hospital, and the handling of the device is simple, which is a remarkable effect as a means for preventing the spread of AIDS.
