Description

Sputum cup

Technical field

The utility model relates to medical treatment to assist detection instrument, more particularly, to a kind of sputum cup for facilitating oscillation to mix.

Background technique

The test of Sputum culturing identification and susceptibility is the most common infection in respiratory system etiological diagnosis method in China, main purpose It is auxiliary diagnosis, determines that pathogenic infection and the formulation for rational therapy scheme provide foundation.Phlegm is trachea-bronchial epithelial cell and alveolar institute The secretion of generation clinically generally takes nature expectoration or suction sputum method to collect sputum sample；In pathologic conditions such as pneumonia, tumours Under, sputum amount, character etc. can all change, and domestic status of carrying out is that operator is chosen using aseptic cotton carrier or oese at present One piece of thick part, Hand Inoculations to blood agar plate, haemophilus plate are taken, Mai Kangkai (or Yihong methylene blue or Chinese blue) is put down On plate and the Luoping Sha Bao plate, since the inhomogeneity and cause of disease of sample are wrapped up by mucin, leucocyte, Sputum culturing result is caused Inaccuracy is also easy to produce and fails to pinpoint a disease in diagnosis or situations such as mistaken diagnosis, influence the therapeutic effect of patient.Therefore it is generally required before Hand Inoculations pair Sputum sample this progress pre-treatment of coming is collected, the pre-treatment of sample is conventional bacteria testing process, culture, identification and susceptibility link Foundation stone, and realize micro-biological samples automation inoculation stand in the breach the problem of to be solved；Clinical research shows this warp of sputum sample After appropriate pre-treatment, machine on sticky sample can be not only solved the problems, such as, while the recall rate of pathogen can be improved.Existing phlegm Sample pretreatment is to be added into the Sputum cup for being loaded with sputum sample sheet and the isometric digestive juice of sputum, then in room temperature or 37 DEG C Under the conditions of, concussion or standing a period of time, it is dilute watery for making sticky this liquefaction of sputum sample.

At present there are mainly two types of the common Sputum cups in market: one is regular cylindrical body spiral mouth Sputum cups, and Sputum cup mouth is smaller, no It is poor so as to cause customer experience conducive to the collection of sputum sample sheet；Another kind is inversed taper platform shape flip Sputum cup, although Sputum cup rim of a cup compared with Greatly, convenient for collecting sample, but since floor space is larger, it cannot mix well and contact with phlegm digestive juice when sample size is few, digest Effect is poor；In addition above two Sputum cup is flat Sputum cup, and when sample size is few, sample is not enough to be paved with whole after addition digestive juice A Sputum cup, causes detecting liquid level to be difficult to realize；Meanwhile existing Sputum cup is since its bottom is circular flat, in bias It easily resonates between Sputum cup and Sputum cup support in concussion blending process, leads to digestion effect difference and expection, in turn result in inoculation and lose Rate raising is lost, time-consuming for sample digestion, reduces the flux of inoculation instrument.

Summary of the invention

The utility model aim is to provide a kind of sputum cup, and the sputum cup structure is simple, can be improved pre-treatment Middle reagent digestion effect.

To achieve the above object, the utility model can take following technical proposals:

Sputum cup described in the utility model, the upper opening cup body including having sealing cover, the top of the cup body is Up big and down small taper type structure, its underpart are prismatic structures or oval rod structure；The bottom wall of the cup body is up big and down small Taper or pyramid-shaped structures, being extended vertically downward at the bottom wall lower surface surrounding edge of cup body has lower part with cup body The height of the consistent annular rib in cross section, the annular rib is greater than or equal to the height of the cup body bottom wall；With the cup It is provided with scale marker vertically upward on the side wall of body bottom wall lower end corresponding position.

The sealing cover screws or activity button-fold is in the upper opening of the cup body.

The utility model advantage is that structure is simple, and using simplicity, processing cost is low.The up big and down small frustum in cup body top Shape structure facilitates the acquisition of sputum sample, and the crawl convenient for mechanical arm and movement of uncapping；Up big and down small taper or pyramid Shape bottom wall can ensure sputum and phlegm digestive juice comes into full contact with mixing, guarantee digestion effect, and when sample size is few, can also lead to It crosses realization detecting liquid level technology and draws sample；The annular rib of bottom of cup is conveniently caught in while protecting cup body bottom wall It shakes in vortex mixer, it is ensured that cup body does not resonate between saucer in bias concussion blending process, improves digestion effect, reduces Inoculation failure rate.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the bottom view of Fig. 1.

Specific embodiment

As shown in Figure 1, 2, sputum cup described in the utility model, the upper opening cup body 2 including having sealing cover 1 are close Capping 1 screws or activity button-fold is in the upper opening of cup body 2；The top of cup body 2 is up big and down small taper type structure, facilitates phlegm The acquisition of liquid sample, while the crawl convenient for mechanical arm and movement of uncapping.The lower part of cup body 2 is prismatic structures or cylindroid Structure, convenient firm is caught in the saucer of concussion vortex mixer, it is ensured that cup body 2 is not between saucer in bias concussion blending process It resonates, improves digestion effect, reduce inoculation failure rate.The bottom wall of cup body 2 be up big and down small taper or pyramid-shaped structures, Mixing can be also come into full contact with phlegm digestive juice when the amount of sputum specimen is less, it is ensured that digestion effect；In the bottom wall lower surface of cup body 2 Being extended vertically downward at surrounding edge has and the consistent annular rib 3 of the lower cross section of cup body 2, the height of annular rib 3 Degree is greater than or equal to the height of 2 bottom wall of cup body, forms protection to the bottom wall of cup body 2, while ensuring that cup body 2 can steadily block and being put in It shakes on the saucer of vortex mixer or is steadily placed on any table top.It is vertical on the side wall of 2 bottom wall lower end corresponding position of cup body to On be provided with scale marker 4, which is the volumetric marks to match with 2 inner cavity of cup body.

Process is digested by same sputum with common Sputum cup on the market using Sputum cup described in the utility model to carry out Comparison, work compare 238 sputum specimens, equally after addition phlegm digestive juice, shake 5min under room temperature, the knot of judgement digestion later Fruit draws sample after 50 μ l are handled with 200 μ lTIP, does not block TIP and is judged to digestion qualification, the result is as follows:

From upper table can, it is evident that Sputum cup described in the utility model digestion qualification rate be substantially better than it is existing on the market Common Sputum cup.
