Description

Press-type transport medium vessel

The present invention relates to a container including a culture medium for collecting and transporting a sample.

All samples for microbiological testing should be sent to the laboratory immediately after collection to ensure the most accurate results. However, if it cannot be inspected immediately, it must be preserved or transported in a suitable environment.

Methods used for transporting specimens include syringes, sterile plastic bottles, etc., depending on the type of specimen (Blood, Pus, Urine, stool, etc.) and the culture environment of the transported bacteria (anaerobic, aerobic, viral, etc.). In general, however, many commercialized container containers, which consist of plastic tubes containing various bacterial media and sterilized disposable cotton swabs, are used.

The conventional transport medium container (EP Publication No. 0223745A119870527EP) is stored and maintained in a state where the sterilized swab and the collecting part are not submerged in the transparent tube in the sample preparation stage. Pressing the capsule, which is a reservoir, with one touch, the film at the lower end of the capsule is ruptured by the upper end of the swab, and the medium in the capsule flows along the outer surface of the swab so that the collecting part is submerged in the medium.

However, the conventional transport medium container is collected from the sample, the transparent tube is in place and the medium is extruded, the medium leaks between the capsule and the grip portion and between the transparent tube and the grip portion is exposed to problems such as collector infection is not used as a transport medium, Immediately used for reagent assay only and discarded on site.

As another medium for transport, the conventional transport medium (EP notification number 0643131A219950315EP) is inconvenient for inspection, such as the problem of contamination of the collector during exposure packaging and the use of a semi-solid transport medium, which causes the transport medium to come to the collector during inspection. Resulted.

The present invention is designed to solve the problems of the conventional transport medium, and improves the problem of the test container used only for the reagent reaction test, so that the medium can use only the liquid medium which is convenient for the test, The medium flows evenly along the inside and outside of the cotton swab to moisten the collecting part, and the triple leak prevention device is installed to prevent the external leakage of the medium so that it can be used for transporting medium.

As a triple leakage preventing device, the transport medium container of the present invention has a structure that prevents the medium from leaking into the gap between the capsule and the grip part when the sample containing the medium is recombined and the capsule containing the medium is pressed again. To have it.

Secondly, it has a double prevention structure that prevents the medium from leaking from the transparent tube and the contact portion of the grip.

Third, it was characterized by having a structure to prevent the flow of the medium by filling a foaming resin that selectively traps the medium under the transparent tube.

In addition, since the conventional transport medium container uses a semi-solid medium, the transport medium is buried in the collecting part at the time of inspection, thereby causing inconvenience in the test, and thus the present invention is designed to exclude the semi-solid medium and use only a liquid medium.

The grip cap 30 is a hat-shaped perforated center portion, the lower portion of the grip cap is provided with a recess 31 indented to engage with the projection 13 external to the grip upper end portion.

When the grip cap 30 is coupled to the grip portion 10, the groove 31 concavely in contact with the grip cap 30 while the grip cap 30 is worn on the upper portion of the capsule 20 having the medium 20 embedded therein. And the grip cap 30 is coupled to the grip part 10 by engaging the outer circumferential protrusion 15 installed on the upper part of the grip part 10.

The grip part 10 is a cylindrical synthetic resin material and is integrally connected to the cotton swab 12 and the funnel 13 including the collecting part 11, and the connection part is connected to the supports 17 and 18 having vent holes. The grip part of the assembled state wraps and protects the cotton swab 12 and the capsule 20, and becomes a passage for downward movement of the capsule 20, and a circular protrusion 15 is formed at the upper end of the grip part 10. The grip cap 30 and the grip part 10 are coupled to each other by being installed in the groove 31 installed in the grip cap 30.

In the middle of the grip portion 10, a stopper 14 is formed with a circular protrusion inscribed inwardly so that the capsule 20 having the medium 22 embedded therein is caught by the stopper 14 when the capsule 20 is downwardly operated. Is installed.

At least two convex protrusions 16 are installed at the lower end of the grip part 10 to secure the coupling with the transparent tube 40, and preferably, U-shaped grooves are installed to prevent the liquid medium from leaking out.

The transparent tube 40 is made of a transparent synthetic resin material, and after the medium is injected, the medium 22 is filled in the lower part, and optionally, a foamed resin (also called a sponge in the market, 41) is embedded in the lower part of the transparent tube so that the liquid Prevent flow.

At the time of sample collection, the transparent tube 40 is separated (FIG. 4), the strain is collected at the collecting unit 11 (see FIG. 5), and the transparent tube 40 is recombined to its original position. After the recombination of the transparent tube to the original position, when the extractor manipulates the capsule 20 containing the medium 22 in one touch, the film 21 at the lower end of the capsule is blown out by the upper end of the cotton swab 13 and the medium 22 ) Flows down inside and outside the swab 12 and then the collecting portion 11 is submerged in the medium 22 (see FIG. 6). It is stopped by a stopper 14 composed of a circular protrusion inscribed therein, and then the capsule is returned to its original shape by the frictional force of the jaw 23 of the lower end of the capsule in which the grip part wall 19 and the medium 22 are embedded. It is comprised so that the outflow of the medium 22 which flowed out may be shut off.

In the present invention, the sample transport container can be bulk packed in 10 units, 20 units, or 100 units by storing a cotton swab in a tube, and conventionally, only one unit individually. Alleviated the inconvenience of opening the sealed bag individually.

During the collection, the cotton swab was removed from the tube, and after collection, it was recombined to its original position, thereby eliminating unnecessary operations such as catching the capsule and the tube crosswise to prevent secondary infection or contact.

After the collection, the operation of locking the collection portion of the cotton swab to the medium was to push the capsule with one touch, so that the liquid medium in the capsule flows down the cotton swab so that the collection portion is submerged in the medium to minimize the loss of the sample.

In addition, the conventional transporting medium uses semi-solid transporting medium to prevent the outflow of the medium, which causes inconvenience to the inspection because the transporting medium is buried in the collecting part during the inspection. To improve it.
