The specific embodiments will now be described as follows:
the embodiment of the scalp fungus specimen collector provided by the invention, referring to fig. 1 and 2, comprises a sampling comb (2) and a sample unloading rod (1), wherein the sampling comb (2) comprises a comb body (21), a hole (211) with a threaded mouth is formed in the upper part of the comb body (21), and 5 scraping teeth (22) are formed in the lower part of the comb body; a semicircular groove (221) is formed in the lower end of the scraping tooth (22); the lower end surface (2211) of the semicircular groove (221) is a semicircular surface; one end of the sample unloading rod (1) is inserted into the hole (211) and then can be connected with the thread of the opening part of the hole (211) in a threaded manner.
The invention provides an embodiment 1 of a sample unloading rod (1), which is shown in fig. 1, 2, 3 and 4, and comprises a ball head part (11) and a holding rod part (12) connected to the lower end of the ball head part (11), wherein one side surface of the ball head part (11) is a smooth surface (111), and the upper end of the other side surface is provided with a groove (112) for scraping a sample in a semicircular groove (221) at the lower end of a comb body (21); the wall surface of the holding rod part (12) close to the ball head part (11) is provided with threads (121) for connecting the hole (211) in a threaded manner. See fig. 1, 2, 4.
The sample unloading bar (1) of the embodiment 2 provided by the invention, see fig. 3 and 5, has a structure similar to the sample unloading bar of the embodiment 1, and is structurally different in that the upper end of one side surface of the ball head part (11) is provided with a sample unloading convex line (113) in the shape of a spiral line convex line for scraping a sample in a semicircular groove (221) at the lower end of the comb body (21).
The sample collection principle of the invention:
the invention moderately extrudes the scalp of the patient through the semicircular arc surface at the lower end of the semicircular groove (221), and collects fungus and bacteria infected under dandruff and in hair follicles into the semicircular groove (221).
When the comb is used, medical staff cleans and disinfects hands of the medical staff, holds the upper part of the comb body (21) by one hand, lightly presses the lower end of the comb body (21) to an area which is formed by surrounding the upper ends of the two sides of the skull before connecting wires between the forehead and the two ears, and/or takes a part of alopecia (namely, sampling is performed to cover a lesion part), and then presses and comb the scalp against the hair growth direction, so that the scraping teeth sink into the lower part of the scalp by about 1mm, and combing and scraping are performed for at least 2 times.
After scalp sampling, medical staff holds the ball head part (11) of the sample unloading rod (1) connected with the upper part of the comb body (21) by the other hand, screws anticlockwise, separates the sample unloading rod (1) from the sampling comb (2), then holds the holding rod part (12), scrapes off the sample in the semicircular groove (221) by using a sample unloading structure (namely a groove or a sample unloading convex line) at the end part of the ball head part (11) of the sample unloading rod (1), smears the sample on a slide, then uses the smooth surface (111) of the ball head part (11) of the sample unloading rod (1) to fix the sample on the slide by an imprinting technology, and then checks the sample on the slide, or places the sample scraped from the semicircular groove (221) into a sterile culture bottle for checking.
After sample unloading is completed, the sample unloading rod (1) and the sampling comb (2) are cleaned and disinfected, a holding rod part (12) of the sample unloading rod (1) is inserted into a hole (211) at the upper part of the comb body (21) after the sample unloading is completed, a ball head part (11) of the sample unloading rod (1) is screwed clockwise, and a wire of the sample unloading rod (1) is received on the sampling comb (2).
The above examples of the present invention are merely illustrative of the present invention and are not intended to limit the embodiments of the present invention. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. Not all embodiments are exhaustive. All obvious changes or modifications which come within the spirit of the invention are desired to be protected.
