Description
Technical field
This utility model, about a kind of sampling apparatus of medical field, particularly relates to the sampling apparatus of the rotary secretions of a kind of nasal cavity.More specifically relate to one and there is the cylindrical nasal secretion sampling apparatus of sampling.
Background technology
At present, because ambient air quality is poor, a lot of antibacterial, virus, microorganism even hazardous particle all can enter in body by respiratory tract as inhalation (inhalatio), cause suction body (such as human body or domestic animal) produce uncomfortable or cause disease.Owing to all there is the sticking nasal secretion of tool in the nasal cavity of these suction bodies, these inhalation (inhalatio)s usually all some adhere to by these nasal secretions, thus to detect nasal secretion be a kind of detection because inhalation (inhalatio) causes the effective detection method fast of disease.
At present, usually adopt cotton stick swab to carry out the endocrine collection of nasal cavity, then the secretions collected carried out antibacterial culturing or process further.Although this method is simple, cotton stick swab is made up of Cotton Gossypii and bamboo let, and be single use.In use, the cotton fiber of cotton stick swab likely comes off and pollutes the secretions collected, and causes the poor effect of sample even to sample failure, and needs repeated sampling, waste time and energy.Meanwhile, in sampling process, this cotton stick swab utilizes the mode of scraping nasal wall to sample usually, and swab end friction nasal membrane, this makes to be sampled object and does not feel well.This utility model, by providing a kind of revolving nasal-cavity sampling device, makes rotational structure gather secretions by the mode adhered in nasal cavity sampling process, reduces the friction between sampling structure and nasal wall, reduce the uncomfortable degree of detected object.After sampling terminates, sample collecting rotor can be sampled again through cleaning and drying, can reuse, and reduces sampling cost.In addition, sampling periphery arranges circular sampling pit, to increase sampling area, strengthens sample effect.The Handheld Division of described sampling apparatus is hollow-core construction, by being connected with Handheld Division by scavenge pipe, injects cleanout fluid, to clean nasal cavity to nasal cavity.
Utility model content
For solving the technical problem in the sampling that exists in above-mentioned this area, this utility model adopts rotary sampling structure collected specimens.After the sampling cylinder contact nasal wall of sampling apparatus, produce the rolling along nasal wall, adhere to the secretions of nasal cavity, finally obtain collected specimens.
The specific embodiments that this utility model adopts:
One has the cylindrical nasal secretion sampling apparatus of sampling, it is characterized in that, comprising:
Handheld Division and sample collecting rotor; Described Handheld Division comprises: stem, the first extension and the second extension;

Described sample collecting rotor comprises sampling cylinder, first protruding and the second projection, and described first projection and described second projection are stretched out from the cylindrical both ends of the surface of described sampling;
Described first pit is protruding for holding described first, described second pit is protruding for holding described second, to enable described sample collecting rotor rotate, and described sample collecting rotor can not be come off in sampling process from described first extension and the second extension;
Described sampling periphery arranges multiple sampling pit, and each described multiple sampling pit is circular pit.The material of described sample collecting rotor is polyethylene or politef.
Further, described circular pit diameter is less than 1/10 of the cylindrical circular cross section diameter of sampling.
Further, described circular pit diameter is less than 1/15 of the cylindrical circular cross section diameter of sampling.

Detailed description of the invention
As Figure 1-4, this utility model provides one to have the cylindrical nasal secretion sampling apparatus of sampling, comprising:
Handheld Division and sample collecting rotor 4; Described Handheld Division comprises: stem 1, first extension 2 and the second extension 3; Described stem 1 is cylindrical, and described stem inside has cylindrical hole 8, the axis of described stem 1 and the dead in line of described cylindrical hole 8; Described stem 1 has first end and the second end.
Described first extension 2 and described second extension 3 extend from described first end along the axis direction of described stem, described first extension 2 and described second extends 3 and is oppositely arranged, the first pit 9 and the second pit is respectively arranged with at the correspondence position of described first extension and described second extension opposite face, described first pit 9 is arranged on described first extension 2, and described second pit is arranged on described second extension.
Described sample collecting rotor comprises sampling cylinder 4, first protruding 5 and the second projection 6, and described first projection 5 and described second projection 6 are stretched out from described sampling cylinder 4 both ends of the surface.
Described first pit 9 is for holding described first projection 5, described second pit is for holding described second projection 6, to enable described sample collecting rotor rotate, and described sample collecting rotor can not be come off in sampling process from described first extension 2 and the second extension 3; Described sampling periphery arranges multiple sampling pit 7, and each described multiple sampling pit 7 is circular pit.
Be sampled body for adapting to difference, described stem diameter can be selected according to the nasal cavity size being sampled object.For increasing versatility, stem diameter is not more than 5 millimeters, and sampling cylinder axial length is not more than 4 millimeters.The cylindrical diameter of usual sampling is not more than 4 millimeters.Stem can be rigid material or elastomeric material.
Further improvement: for increasing sampling cylinder 4 and nasal secretion contact probability, sampling cylinder diameter can be greater than stem diameter.
Under partial picture, need to inject cleanout fluid to nasal cavity, nasal cavity is cleaned.Because stem 1 inside comprises cylindrical hole 8, the second end of Handheld Division can external cleaning device, cleaning solution is injected nasal cavity by described cylindrical hole, and flows out from the first end of Handheld Division, clean nasal cavity.Because first end is provided with sampling cylinder 4, sampling cylinder has barrier effect to the cleaning solution flowed out, the discomfort avoiding cleaning solution directly to impact nasal cavity producing.
The material of sample collecting rotor can be polyethylene or politef.For increasing the contact area of sampling cylinder and nasal secretion, circular sampling pit can be set at sampling periphery.The diameter of pit is be less than sampling cylinder circular cross section diameter 1/10, is preferably less than 1/15.Sample collecting rotor is by injection molding manner manufacture.
In sampling process, first by the sample collecting rotor assembling after cleaning-drying to Handheld Division.Then sampling apparatus is stretched into nasal cavity.After arriving precalculated position, move back and forth three to five times along stem axial direction, sample collecting rotor is rolled on nasal wall, and nasal secretion will adhere to sample collecting rotor surface.Subsequently, sampling apparatus is taken out.Finally sample collecting rotor is taken off and carry out antibacterial culturing, or secretions is separated.Sample collecting rotor after using is carried out cleaning and drying, to reuse.
The structure that this utility model adopts is simple, light and handy, and sampling fast, conveniently, can not produce secondary pollution to the sample gathered.Sampling apparatus can be reused, to reduce sampling cost after cleaning.
