Description

Be suitable for phlegm sample collection and auxiliary device of pretreatment

Technical Field

The utility model relates to the technical field of experimental auxiliary equipment, in particular to an auxiliary device suitable for sputum specimen collection and pretreatment.

Background

The sputum specimens in the work of smear microscopy, improved Roche medium (L-J) culture detection and other molecular biology detection of mycobacteria need to be collected and pretreated, and a collecting container needs to have good tightness and no leakage. The purpose of pretreatment is mainly two: (1) removing undesired bacteria other than mycobacteria (decontamination); (2) the liquefied sample is convenient to detect.

Most of the existing sputum collection containers are ordinary sputum bottles with covers. The pretreatment step comprises two steps: (1) sucking the specimen in the sputum flask into an empty tube by using a suction tube; (2) adding 1-2 times of 4% NaOH into the tube, digesting, shaking, mixing, standing, and performing subsequent detection. However, the sputum specimen is sticky in nature, so that the operation of taking the sputum specimen into an empty tube by using a suction tube is difficult, and aerosol is easily generated in links such as multiple suction, blowing and beating, so that the biological potential safety hazard is caused.

In conclusion, the utility model designs the auxiliary device suitable for sputum specimen collection and pretreatment.

Disclosure of Invention

Drawings

The utility model is described in detail below with reference to the drawings and the detailed description;

FIG. 1 is a schematic view of the structure of the present invention;

fig. 2 is a cross-sectional view of the upper cover of the present invention.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

Referring to fig. 1-2, the following technical solutions are adopted in the present embodiment: the utility model provides a be suitable for auxiliary device of phlegm sample collection and pretreatment, includes upper cover 1, button 2, device body 3, lower cover 4 and sharp mouth 5, and device body 3 is soft body, and the top of device body 3 is screwed and is sealed have upper cover 1, and the bottom of device body 3 is provided with sharp mouth 5, and sharp mouth 5 outside has connect lower cover 4 soon, upper cover 1 in pre-installation 4% NaoH digestive juice, upper cover 1 top is provided with button 2.

It is worth noting that the inner wall of the upper cover 1 is provided with a sharp thorn 6, 4% of the NaoH digestive juice is pre-filled in a puncture inner container 7, and the bottom of the upper cover 1 is a digestive juice outlet 8.

It is worth noting that the bottom of the upper cover 1 is in an inverted cone shape, so that digestive juice can flow out of the digestive juice outlet 8 into the device body 3 conveniently.

In addition, the outer wall of the device body 3 is also provided with scales.

The specific operation of the embodiment is as follows: at first, unscrew upper cover 1, spit the sputum inside device body 3, according to the scale on the device body, spit the suitable amount of sputum, then screw upper cover 1 again, press the button, the spine inner bag for 4% NaoH digestive juice of pre-installation flows to device body 3 from digestive juice export 8 in with the processing before the sputum mixes, the defect that the tradition carries out the operation many times with the straw is avoided to this kind of mode, wait sputum and digestive juice mix after stewing, take off the lower cover 4 of bottom, extrusion device body 3 extrudes the mixed liquid of the inside, carry out subsequent detection again.

The device body of the embodiment adopts a soft device, so that the mixed liquid in the device body can be conveniently extruded like squeezing toothpaste, and the device is convenient and quick to operate, safe, reliable and high in practicability.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
