Referring to fig. 1 to 3, a gynecological sampling assembly according to an embodiment of the present invention may be used for gynecological sampling, and includes a test tube 20 and an acquisition swab 10.
Specifically, tube 20 may be made of a transparent plastic material. The collection device is suitable for being accommodated in the test tube 20, and comprises a holding rod 101 and a collection head 102, wherein the holding rod 101 is detachably connected with the collection head 102, so that a user can operate to rotate the collection head 102, that is, when the collection device is used, an operator can hold the holding rod 101 with his/her hand, extend the collection head 102 into a patient through the vagina, and rotate the holding rod 101 to drive the collection head 102 to rotate so as to collect a sample.
The collecting head 102 may be made of medical plastic, such as PVC material, PE material, etc., the collecting head 102 includes a cylinder 1021 and a ball 1022, wherein a receiving cavity is defined in the cylinder 1021, a plurality of spiral channels 1021a communicating with the receiving cavity are disposed at intervals on a peripheral wall of the cylinder 1021, each of the spiral channels 1021a is spirally disposed around an axis of the cylinder 1021, one end of the spiral channel 1021a starts from a lower end of the cylinder 1021, and the other end of the spiral channel 1021a ends from an upper end of the cylinder 1021.
The cylinder 1021 has a rotation operation direction in which an operator drives the cylinder 1021 to rotate by using the grip lever 101 at the time of sampling, the rotation operation direction being opposite to the screw direction.
The peripheral wall of the cylinder portion 1021 is further provided with a plurality of spiral scraping strips 1021b protruding radially outwards of the cylinder portion 1021 at intervals, the plurality of spiral scraping strips 1021b are in one-to-one correspondence with the plurality of spiral channels 1021a, each spiral scraping strip 1021b is arranged next to a corresponding one of the spiral channels 1021a, and in the rotation working direction, the spiral channels 1021a are positioned in front of the corresponding spiral scraping strips 1021b, and preferably, the spiral angles of the spiral scraping strips 1021b and the spiral channels 1021a are both 45-80 degrees. That is, the number of spiral scratch pieces 1021b is equal to the number of spiral channels 1021a, and each spiral scratch piece 1021b is disposed behind the spiral channel 1021 a. Since the spiral direction of the spiral channel 1021a and the spiral scraping strip 1021b is opposite to the rotation direction, when the collection head 102 rotates along the rotation direction, the spiral scraping strip 1021b can scrape the sample in the vagina, so that the sample flows along the spiral direction and then flows into the accommodating cavity from the spiral channel 1021 a.
A ball head 1022 is formed at the lower end of the cylinder 1021, and the ball head 1022 has a spherical inner wall, and the inner wall of the receiving chamber and the spherical inner wall are provided with a medical cotton layer of a predetermined thickness. That is, the ball head 1022 is formed in a hemispherical shape and has a hollow structure, on one hand, the spherical ball head 1022 facilitates the insertion of the collection head 102 into the patient, on the other hand, the interior of the ball head 1022 can accommodate more sample, and the sample is not easily discharged from the ball head 1022.
When a user drives the cylinder portion 1021 to rotate through the grip lever 101, the spiral scraping bar 1021b scrapes a sample in the vagina, and the sample flows along the spiral direction of the spiral scraping bar 1021b, enters the accommodating cavity through the spiral channel 1021a and is attached to the medical cotton layer.
In a specific use process, the holding rod 101 of the collecting swab 10 can be held by hand, the collecting swab 10 is stretched into a patient through vagina, and then the holding rod 101 is rotated along the rotation working direction, so that the collecting head 102 rotates along the rotation working direction, at this time, the spiral scraping strip 1021b on the cylinder portion 1021 scrapes a sample in the body, the sample can flow along the spiral direction of the spiral scraping strip 1021b and flow into the accommodating cavity of the cylinder portion 1021 and the ball head portion 1022 through the adjacent spiral channel 1021a, and the medical cotton layer with a preset thickness is arranged on the inner wall of the accommodating cavity and the spherical inner wall of the ball head portion 1022, and has a strong adhesion effect, so that the sample can be adhered to the medical surface layer and is not easy to flow out from the spiral channel 1021 a.
According to the gynecological sampling assembly provided by the embodiment of the invention, the cylinder part 1021 is provided with the plurality of spiral channels 1021a and the spiral scraping strips 1021b at intervals, when the gynecological sampling assembly is used, the spiral scraping strips 1021b rotate along the rotating working direction, samples in the vagina are scraped, flow along the spiral direction of the spiral scraping strips 1021b, enter the accommodating cavity through the spiral channels 1021a and are attached to the medical cotton layer, so that more samples can be collected, the sufficient sample quantity is ensured, and the detection requirement can be met. In addition, since the collected sample is located in the accommodating chamber and is adhered to the medical cotton layer, when the collection swab 10 is put into the test tube 20, the sample is not easy to contact the tube wall of the test tube 20 and is not easy to flow out of the accommodating chamber, so that the sample is basically not lost in the process of delivering the sample, and the reliable detection is ensured.
Referring to fig. 3 to 4, in one embodiment of the present invention, an opening is formed between the one ends of two adjacent spiral scratch strips 1021b, and the one ends of two adjacent spiral scratch strips 1021b are closed, that is, the one ends of two spiral scratch strips 1021b are closed, so that when the collection head 102 is rotated, a sample is conveniently introduced from the opening between the two spiral scratch strips 1021b and flows along the spiral scratch strips 1021 b. And the one ends of the two spiral scraping strips 1021b are closed, so that the sample is prevented by the closed ends, and the sample can flow into the spiral channel 1021a smoothly.
Illustratively, the upper end of the cylinder part 1021 has an annular blocking part which surrounds the peripheral wall of the cylinder part 1021 and protrudes radially outward along the cylinder part 1021; the other end of the spiral channel 1021a is terminated by the annular blocking portion, so that the other ends of the two adjacent spiral scraping strips 1021b are sealed, and preferably, the annular blocking portion and the cylinder portion 1021 are integrally formed, so that the other ends of the spiral scraping strips 1021b can be sealed through the annular blocking portion, and the structure is simple.
