Abstract
The invention discloses a biological sampling swab, which comprises a connecting portion, a swab component and a container for containing reaction solution. The swab component is disposed at the lower end of the connecting portion. A reaction tube is sleeved to the bottom of the swab component. The swab component extends into the reaction tube. The connecting portion is provided with a liquid passage inside. A socket for moving down the container is reserved at the upper end of the connecting portion. The outer wall of the container is in sealed fit with the inner wall of the socket. At leastone spike is disposed on a base of the socket. A thin film is disposed on the lower portion of the container. After the container is moved down, the thin film is pierced by the spikes, and the reaction solution in the container flows into the reaction tube through the liquid passage. The biological sampling swab can be used for sampling and reaction testing simultaneously, and pollution in sampling and passing is well avoided. The biological sampling swab is convenient to operate, safe and reliable.
Description
Technical field
The present invention relates to a kind of biological detection instrument, especially relate to a kind of biological sampling swab.
Background technology
At biological field, collection and the transmission of biological specimen (comprising biomass cells and biomolecules) are important link.In the process of biological specimen collection and transmission, swab sampling is the most frequently used and sample mode the most easily.
At present, the structure of biological sampling swab commonly used comprises swab handle and swab head, and swab handle is a bar-shaped cylinder, has certain degree of hardness, and an end is portion of the handle, and the other end can be used as the position that makes the swab head.Put in the test liquid (the plain enzyme of fluorescent worm) with the bacterium that the sampling swab samples, and then come the number of bacterium in the detection statistics test liquid with testing apparatus.There are the following problems for the prior biological sample mode: germy sampling swab need be transferred in the test liquid, operated cumbersomely, operation sampling swab or test liquid may be contaminated simultaneously, cause the biological specimen sampling inaccurate.
Summary of the invention
Technical problem to be solved by this invention provides a kind of easy to operate, safe and reliable biological sampling swab.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of biological sampling swab, comprise connection section, swab assembly and the container that holds reaction soln, described swab assembly is arranged on the lower end of connection section, it is characterized in that being arranged with reaction tubes under the described connection section, described swab assembly stretches in the described reaction tubes, be provided with fluid passage in the described connection section, described connection section upper end is provided with the hole seat that moves down for container, be sealed and matched between the inwall of described container outer wall and hole seat, the base of described hole seat is provided with at least one sharp object, described container bottom is provided with film, after container moves down, sharp object punctures film, and the reaction soln in the container enters in the reaction tubes through fluid passage.
The base of described hole seat is provided with four sharp objects, and described four sharp objects are evenly distributed on the fluid passage top.
The tapered body of described sharp object, described sharp object and connection section are wholely set.
Described swab assembly comprises swab handle and swab head, and described swab head arranges the swab handle lower end.
Described swab handle is hollow form, fixes after described fluid passage is stretched in described swab handle upper end.
Described swab head is cotton swab head, and described cotton swab head encases described swab handle lower end.
Annular solid and outer shroud body in described connection section lower end has been wholely set form annular recesses between described interior annular solid and the described outer shroud body, and the upper end of described reaction tubes is stretched in the described annular recesses and can be enclosed within on the described interior annular solid.Before not using, in being enclosed within, reaction tubes on the annular solid, protects swab handle and swab head.During sampling, reaction tubes can be removed, put again after waiting sampling to finish.
Described container is straight-tube shape, and described film is arranged on the lower ending opening of described straight-tube shape container.
Be wholely set wear ring on the outer wall of described container, when container did not move down, wear ring leaned against on the wall end of hole seat, and after container moved down, the inwall of wear ring and hole seat closely cooperated.When container did not press down, wear ring can be used as the untapped mark of the present invention, when container because of press down move down after, can further increase tightness, the time do not allow liquid overflow in extruding, make liquid better toward dirty.
The arranged outside of described connection section has annular recessed filling portion, and described annular recess is certain radian.The recessed filling of annular portion makes things convenient for hand to pinch.Described reaction soln is the plain enzyme of fluorescence worm, and described film is the aluminium film.
Compared with prior art, advantage of the present invention is when needs are sampled, and earlier reaction tubes is extracted, directly with swab head contact biological specimen, after collecting biomass cells or biomolecules, reaction tubes is put, and behind the following pressure vessel, sharp object punctures film, reaction soln in the container enters in the swab handle through fluid passage, after penetrating cotton swab head at last, flow in the reaction tubes, the reaction soln in the reaction tubes and the biomass cells on the swab head or biomolecules are carried out chemical reaction.The present invention can finish simultaneously the sampling and test reaction, can avoid well sampling and transmittance process in pollution, the present invention is easy to operate, and is safe and reliable.
