Figure 2 shows the structure of the cap in the sputum cup of figure 1.

In the present application, all the figures are schematic and are only intended to illustrate the principles of the present invention and are not drawn to scale.

Detailed Description

In the present application, the directional terms or limitations "up", "down", etc. used in the present application are all referred to with reference to fig. 1. They are not intended to limit the absolute positions of the parts involved, but may vary from case to case.

Fig. 1 schematically shows the structure of a sputum cup 100 for sputum liquefaction according to the present invention. As shown in FIG. 1, the sputum cup 100 includes a cup body 10, and the cup body 10 is used for holding sputum. Cup 10 includes cup lateral wall 11 and bottom 12 that forms an organic whole with cup lateral wall 11, and the upper end of cup 10 forms the open end to form a container that can hold sputum. Cup 10 is configured such that the cross-sectional area decreases from the open end to the cup bottom 12. In one embodiment, cup 10 is configured in a frustoconical shape.

According to the utility model, the thickness of the cup bottom 12 is set to be larger than that of the cup body side wall 11. The thickness of the side wall 11 of the cup body is 0.05mm-0.1mm, and the thickness of the bottom 12 of the cup body is 0.2mm-0.4 mm. In one embodiment, cup 10 is made of plastic.

As shown in FIG. 1, the sputum cup 100 further includes a cap 20. The lid 20 is adapted to sealingly engage the cup to seal the cup 10 to prevent sputum contained within the cup 10 from escaping. In one embodiment, the cap 20 is made of plastic.

According to the present invention, a flange 13 extending radially outward is provided at the circumferential edge of the open end of the cup body 10. The thickness of the flange 13 is set to 2mm to 4mm, and the outward extension dimension is not less than 4 mm. Meanwhile, the circumferential edge of the cup cover 20 is flanged inwards to form a clamping groove 22, and the clamping groove 22 can be matched and installed with the flange 13 at the opening end of the cup body 10 to form connection. Therefore, the cup cover 20 is fittingly installed with the flange 13 through the clamping groove 22, so that a clamping sealing connection is formed. The cup cover 20 can not only ensure the sealing performance of the sputum cup 100, but also effectively avoid the contact of sputum with the external environment, thereby improving the liquefaction effect of the sputum, effectively avoiding the contamination of the inspection environment and other personnel caused by the outflow of the sputum, effectively avoiding the germ transmission in the sputum, further avoiding the infection of diseases and improving the safety performance of the sputum cup 100.

According to the utility model discloses, sputum cup 100 still includes burette 30, and burette 30 is arranged in to adding liquefied liquid in order to carry out liquefaction to the sputum or absorb the sputum to cup 10. For example, when the tuberculosis sputum is liquefied, 4% NaOH is added into the cup body 10 by using the dropper 30 for concussion liquefaction, and the liquefied sputum in the sputum cup 100 is absorbed by the dropper for subsequent detection. In this embodiment, the cap 20 is provided with a through hole 21. As shown in fig. 2, the through hole 21 is provided at a non-center of the cap 20. The dropper 30 adds liquefied liquid or sucks sputum to the cup body 10 through the through hole 21. From this, in the processing procedure that liquefies the sputum, need not to open bowl cover 20 and can realize adding the liquefaction liquid or absorbing the sputum and carry out follow-up detection in cup 10, sputum outflow when can effectively avoiding shaking the liquefaction, and its easy operation, and can effectively avoid polluting, the security performance height.
