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 liquefaction anti-pollution sputum cup 100 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.

As shown in fig. 2, a convex portion 13 extending radially inward is provided at the circumferential edge of the open end of the cup body 10. The thickness of the convex portion 13 is set to 6mm, and the thickness is set to 10-14 mm. Meanwhile, the circumferential edge of the cup cover 20 is provided with an inward flange, the flange is provided with a radial inward groove 22, and the groove 22 can be matched and installed with the bulge part 13 at the opening end of the cup body 10 to form connection. Thus, cap 20 is fittingly mounted with boss 13 via groove 22 to form a snap-fit sealing connection. 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, the sputum cup 100 further comprises a dropper (the dropper is used when in use, not included in the utility model), and the dropper is used for adding liquefied liquid to the cup body 10 to liquefy or absorb the sputum. For example, when the tuberculosis sputum is liquefied, 4% NaOH is added into the cup body 10 by using a dropper for concussion liquefaction, and the liquefied sputum in the sputum cup 100 is sucked by the dropper for subsequent detection. In this embodiment, the cap 20 is provided with a through hole 21. As shown in fig. 3, the through hole 21 is provided at a non-center of the cap 20. The dropper adds liquefied liquid or sucks sputum into 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.

As shown in fig. 1, a sealing plug 40 is press-fitted into the through-hole 21. The sealing plug 40 is preferably a rubber sealing plug (existing, directly purchased). Sealing plug 40 is used for sealing cup 10 to avoid sputum and external environment to contact, guarantee the accuracy of sputum liquefaction detection effect. The sealing stopper 40 is configured to be opened to allow the dropper to add a liquefied solution or suck sputum into the cup body 10 through the through hole 21. When nucleic acid extraction needs to be carried out, only the sealing plug 40 needs to be pulled out, then the dropper is operated at the through hole 21, the cover does not need to be opened, the operation is convenient, the pollution of sputum outflow to the detection environment and other personnel can be effectively avoided, and the safety is improved.

In the present invention, the sealing plug 40 comprises a first cylindrical portion and a second cylindrical portion. The first cylindrical portion and the second cylindrical portion are integrally provided, and the first cylindrical portion has a smaller diameter than the second cylindrical portion, thereby forming a stepped portion at a junction of the first cylindrical portion and the second cylindrical portion. The first cylinder part of the sealing plug 40 is mounted in the through hole 21 of the cup cover 20 in a pressing manner, so that sealing is formed between the sealing plug and the through hole 21 to ensure the sealing of the sputum cup 100, the axial end surface of the step part is in close contact with the upper end surface of the cup cover 20, and the outer wall surface of the first cylinder part is provided with a radial bulge to enhance the sealing between the sealing plug and the cup cover and prevent the sealing plug 40 from falling outwards. The end face of the shaft of the second cylinder part of the sealing plug 40 connected with the first cylinder part contacts with the upper end face of the cup cover 20 to form sealing, and the structure of the sealing plug 40 can enhance and ensure the sealing performance between the sealing plug and the cup cover 20, thereby effectively ensuring the sealing of the through hole 21.

According to the utility model, an extension part 23 for taking the sputum cup 100 is arranged at the radial outer side of the cup cover 20. The extension 23 is disposed radially outward of the through hole 21 in the cap 20. In one embodiment, the extension 23 is configured in a semi-circular shape and extends radially outward by a dimension of 14 mm. In the sputum testing process, the detection personnel can take the sputum cup through the extension, and the detection personnel of being convenient for operate.

According to the utility model discloses an anti-pollution sputum cup 100 of sputum liquefaction is particularly useful for the liquefaction of tuberculosis sputum, and sputum cup 100 disposable.

According to the utility model discloses an anti-pollution sputum cup 100 of sputum liquefaction can the sputum sample carry out liquefaction and handle to can avoid opening bowl cover 20 in the testing process, thereby the sputum flows out and the pollution that causes when effectively having avoided absorbing the sputum after the liquefaction, has improved the security performance of whole sputum liquefaction process. Adopt the block sealed between bowl cover 20 of phlegm cup 100 and the cup 10, can effectively guarantee the sealing performance of phlegm cup 100, avoid phlegm sample and external environment to contact, can guarantee the liquefaction effect of phlegm, and further avoid the phlegm to flow out and cause the pollution to external environment and other personnel to show the risk that has reduced the transmission disease. In addition, the sputum cup 100 has simple structure and low cost, and the operation of using the sputum cup 100 to carry out the sputum liquefaction treatment is simple and convenient, the liquefaction efficiency is high, and the liquefaction effect is good.
