Abstract

PURPOSE:To easily prepare a bacterial liquid and to improve the safety of sanitation control by attaching a cap to a test tube which houses plural pieces of spherical solid materials and is graduated. CONSTITUTION:The cap 2 made of a synthetic resin material, polypropylene is attached to the test tube 1. Plural pieces, 2-6 pieces of the spherical solid materials (balls) 3 of about the size at which the balls can rotate in contact with each other in the test tube 1 are then housed into the test tube 1. The test tube 1 is graduated with every 0.5ml or 1ml or 2ml. A funnel-shaped adapter 4 is used to facilitate the transfer of expectoriation into the test tube 1 at the time of taking the expectoriation into the test tube 1. Thereafter, 4vol of 4% sodium hydroxide is added to 1 vol specimen and the test tube 1 is hermetically closed by the cap 2. The test tube is then oscillated to uniformize the specimen. The prepn. of the bacterial liquid is thereby facilitated and the safety of sanitation control is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a medical field or a sputum processing device used in the medical field.

[Background Art] In the medical field or medical field, when diagnosing a bacterial disease, it is necessary to collect a sample from a patient and test whether or not specific bacteria are detected in the sample. Ru. In this case, sputum from a patient is sometimes used as a test material, but if sputum is used as it is, it is too viscous and is therefore not suitable as a specimen for isolation culture.

Normally, chemicals are added to the collected sputum to reduce the viscosity of the sputum and homogenize it, making it a specimen for isolation and culture, but in this case, physical force must be applied to mix the medicine and sputum. Certain fungicides may be added to kill bacteria other than the target bacteria.

Conventionally, the general methods for treating sputum include: ■ Inhaling and expelling the drug and sputum with a pipette, and repeating this process to equalize the volume; ■ Storing the sputum in a container with a protrusion on the inside. However, a method is used in which the container is vibrated using a vibration VIR to equalize it.

The method described in ① above, in which the medicine and sputum are inhaled and expelled to equalize them, is a simple method, but the mixture of medicine and sputum forms bubbles, and since the container is operated with the container open, when the bubbles break, bacteria can form. This has the disadvantage that it is extremely undesirable in terms of hygiene control, as there is a possibility that the liquid may jump out of the container.

In addition, the method described in (■) above, in which a container containing sputum is vibrated with a shaker to homogenize it, can be operated without opening the container, so there is no problem in terms of safety compared to method (2) above, but it does not result in homogenization. This method cannot be said to be satisfactory either in terms of the time required or the degree of equalization.

DISCLOSURE OF THE INVENTION The present invention provides a device for treating sputum that overcomes the drawbacks of the prior art as described above.

That is, the present invention provides a sputum processing device comprising a cap attached to a graduated test tube containing a plurality of spherical solid materials, and a sputum processing device comprising the test tube and a funnel-shaped adapter. It provides processing equipment.

Below, the sputum processing device according to the present invention will be explained in detail.

The material used for the test tube in the device of the present invention is not specified, but it is preferably made of synthetic resin, especially polypropylene.The cap can be attached to the test tube in any format. Any ζ is applicable as long as it can seal the test tube well.

For example, a stopper type, a lid type, etc. are preferably used, but it is also possible to apply a screw cap type or a push-button type to the lid type.

The material of the spherical solid material is not specified, but any organic material such as synthetic resin or inorganic material such as glass or crystal can be used. Preferably, a glass ball is used.

The number of spherical solid materials used is a plurality, for example, 3 to 6, and the size is such that they can contact and rotate in a test tube.

Usually, in a test tube with an inner diameter of 14 m to 17 mm, the ball size is 2 mm to 7 mm in diameter.

The scale on the test tube is 0.5nZL or I.
It is best to increments every IIN or 2 rll.

The sputum processing device according to the present invention is used, for example, as follows.

First, sputum is taken into a test tube. At this time, using a funnel-shaped adapter makes it easier to transfer the sputum into the test tube. Add a predetermined amount of aqueous sodium hydroxide solution to a test tube containing sputum.6 Usually, 4 volumes of 4% sodium hydroxide are added to 1 volume of sample.

At this time, a sputum treatment agent such as N-acetyl cysteine can also be added. Seal the test tube with a cap and vibrate on a shaker to equalize.

The sputum treatment device according to the present invention has the following characteristic advantages.

(1) Since the bacterial solution is prepared in a closed system in a test tube, bacteria do not come out and it is safe in terms of hygiene management.

(2) Since the instruments can be sterilized in advance, the flow preparation operation becomes easier.

(3) Compared to conventional methods, the operation is simpler and homogeneous specimens can be obtained in a shorter time.

(4) Since it has a scale, the amount of sputum collected can be seen at a glance, so the amount of sodium hydroxide aqueous solution to be added can be added based on the scale, and there is no need to measure it in advance. .

(5) The use of polypropylene materials for test tubes and caps further provides the following advantages.

■ It won't break even if dropped, and there is little risk of licking.

■ Disposable products are provided.

■ Since the product can be sterilized using an autoclave during manufacturing, no toxic substances remain and there is no effect on the specimen.

(6) By using the adapter, sputum can be transferred directly from the patient's mouth to the device.
