Description

Portable subgingival plaque sampling rod

The technical field is as follows:

the utility model relates to a portable subgingival plaque sampling rod.

Background art:

currently, a curette method and an adsorption method are common sampling methods for subgingival plaque in the oral cavity.

1) Curette method: typically, a sterile periodontal curette is inserted into the periodontal pocket, and the subgingival plaque in the pocket is scraped off and placed in a sterile collection tube. The disadvantages are as follows: (1) the periodontal curettage device has a large and sharp working head, which often causes discomfort and pain to the patient. (2) The curette is used repeatedly after disinfection, and if a plurality of site samples are taken, a large number of instruments are needed, so that the curette is inconvenient to use. (3) Easily cause the problems of local gum bleeding, pollution and the like. (4) The method mainly comprises the step of mechanically scraping bacterial plaque to generally obtain attached subgingival bacterial plaque, and the quantity of the collected bacterial plaque is small and possibly not enough for subsequent detection.

2) An adsorption method: the adsorption method is usually a filter paper method/a moisture absorption paper tip method. The specific operation method comprises inserting the moisture absorbing paper tip or the cut filter paper strip (2 x 10mm) into periodontal pocket along tooth surface, stopping for 30s under resistance, taking out, and placing into a sterile collecting tube. The disadvantages are as follows: (1) the cutting and sterilization of the filter paper strips and the paper tips are required in advance, and the operation is complicated. (2) The paper tip or the filter paper strip needs to be clamped by tweezers, and the tweezers are easy to slip off and cause pollution. (3) The filter paper and the moisture absorption paper tip become soft after meeting water, can not move under the gum and can only be adsorbed in situ. (4) Non-adherent subgingival plaque is collected primarily and is collected in small quantities, which may be insufficient for subsequent testing.

The utility model content is as follows:

the utility model provides a portable subgingival plaque sampling rod for solving the problems in the prior art.

The technical scheme adopted by the utility model is as follows:

a portable subgingival plaque sampling rod comprises

The handle comprises a handle part and a connecting part which are integrally formed, and an angle of 130 degrees and 140 degrees is formed between the connecting part and the handle part;

the sampling head comprises an integrally formed sampling part and a breakable part, the breakable part is connected with the connecting part, the sampling part and the connecting part form 90-100 degrees, and sampling cotton made of polyester fibers wraps the sampling part.

Furthermore, the sampling part is a conical structure with a narrow head part and a wide tail part, the length of the sampling part is 8mm, the diameter of the head part of the sampling part is 0.5mm, the diameter of the tail part of the sampling part is 1mm, and the breakable part and the tail part of the sampling part are integrally formed.

Furthermore, the breakable part is provided with a notch for breaking.

Further, the material of the handle and the sampling head is polypropylene.

Furthermore, the tail end of the connecting part is provided with a connector, the connector and the connecting part mutually form 90-100 degrees, the breakable part is fixedly connected with the connector, and the sampling head is vertical to the connecting part.

Further, the handle is 9-10cm in length and 4-5mm in diameter.

The utility model has the following beneficial effects:

1) the utility model is a disposable operation tool, is convenient and fast to operate and effectively avoids pollution; the polyester fiber is adopted for sampling, the water absorption of the polyester fiber is good, the sampling amount can be increased, the possibility that plant DNA pollution is brought by cotton fibers is avoided, the subsequent PCR or genome detection is influenced, and the problems that the water absorption of nylon fibers is poor possibly, the sampling amount is insufficient and the like are avoided;

2) the collecting device can move left and right under the gum, is lifted up and down, has mechanical collecting and adsorptive collecting capabilities, can simultaneously adopt adhesive and non-adhesive subgingival bacterial plaque, has large collected sample amount and is convenient for meeting the subsequent detection requirement;

3) the L-shaped design simulates the angle of the periodontal probe, is convenient to insert into the periodontal pocket, and is particularly convenient to operate for the posterior tooth area.

Description of the drawings:

FIG. 1 is a block diagram of the present invention.

Fig. 2 is a partially enlarged view of the present invention.

The specific implementation mode is as follows:

the utility model will be further described with reference to the accompanying drawings.

Referring to fig. 1 and 2, the portable subgingival plaque sampling rod comprises a handle 1 and a sampling head 2.

The handle 1 comprises a handle part 11 and a connecting part 12 which are integrally formed, wherein the handle part 11 is 9-10cm long, 4-5mm in diameter and cylindrical, and is convenient to hold. The connecting portion 12 is a continuation of the handle portion at an angle of 130 and 140 degrees to the handle portion to facilitate insertion of the sampling tip into the periodontal pocket, particularly in the posterior dental region.

The sampling head 2 comprises an integrally formed sampling portion 21 and a breakable portion 22. The tail end of the connecting part 12 is provided with a connector 13, the connector 13 and the connecting part 12 form an angle of 90-100 degrees, the breakable part 22 is fixedly connected with the connector 13, and the sampling head 2 is vertical to the connecting part 12. The sampling part 21 is wrapped with sampling cotton made of polyester fiber (similar to a cotton swab).

The sampling head is wrapped by polyester fiber, so that the water absorption is good, and the sampling amount can be increased. The possibility that the cotton fiber can bring plant DNA pollution is avoided, and the subsequent PCR or genome detection is influenced. The problems that the nylon fiber possibly has poor water absorption, the sampling amount is insufficient and the like are avoided.

The sampling part 21 is a conical structure with a narrow head part and a wide tail part, the length of the sampling part 21 is 8mm, the diameter of the head part of the sampling part 21 is 0.5mm, the diameter of the tail part is 1mm, the handle 1 and the sampling head 2 are made of polypropylene, and the breakable part 22 and the tail part of the sampling part 21 are integrally formed.

The sampling head is 90-100 degrees with the connecting part 12, and the partial enlarged view is shown as 2, which is a taper with a narrow head part and gradually enlarged backwards. A break 23 is provided at a distance of 2mm from the end of the connector 13 to serve as a break. After the collection of the subgingival plaque is completed, the sampling part can be put into the sample collecting pipe, and the fracture is processed at the pipe orifice and is broken off, so that the sampling part is remained in the sample collecting pipe.

The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the utility model and these modifications should also be considered as the protection scope of the utility model.
