Description

Mixed specimen cup for sample collection Technical Field The utility model relates to the field of medical detection, in particular to a mixed specimen cup for sample collection. Background In the process of sample collection and treatment, especially in the process of treating a biological sample (such as sputum, urine, feces and other body fluid samples) with infectivity, a specific treatment reagent is usually required to be added after the sample is collected so as to achieve the purposes of keeping the activity of the sample, inhibiting the growth of microorganisms, delaying the spoilage process of the sample, pretreating the sample and the like. However, at present, methods of uncapping and liquid adding, double-layer container and premixing are mainly adopted for mixing biological samples and reagents, and the methods have disadvantages. The uncapping and liquid adding method requires an operator to manually open the cover of the specimen cup and add reagent into the cup. The process is complex, the risk of sample overflow exists, the risk of infection is high, the biological safety of operators is threatened, and meanwhile, the samples are also easily polluted by external environmental factors, so that the accuracy of the subsequent detection results is affected. The double-layer container method is characterized in that two independent containers are used for respectively containing the sample and the reagent, and the direct contact between the sample and the reagent is avoided to a certain extent, but the operation process is complex, and the use of the two containers increases the cost. The pre-mixing method is to preset the reagent in a sample cup used for sampling. While this approach simplifies the procedure, prolonged contact of the reagent with the sample can affect the accuracy and timeliness of the sample, especially when handling time sensitive samples, such as viral samples, premixing can result in reduced activity of the sample. In summary, the existing specimen cup technology has urgent need for improvement in aspects of biosafety, sample quality assurance, operation convenience and the like. Disclosure of utility model The utility model aims to solve the problems, and provides a mixed specimen cup for sample collection, which can improve the biosafety and the operation convenience during collection and effectively reduce the risk of sample pollution or quality damage. In order to achieve the above purpose, the technical scheme adopted by the utility model is that the mixed specimen cup for collecting samples comprises a cup body and a cup cover matched with the open end of the cup body, a liquid storage cabin extending into the cup body is arranged on the cup cover, the lower end of the liquid storage cabin is opened and the opening is sealed by a sealing film, a puncture part is arranged in the liquid storage cabin, the lower end of the puncture part is provided with a sharp part, the upper end of the puncture part is connected with a pressing part, the pressing part is arranged on the cup cover, the pressing part cannot displace when the pressing part is not acted by external force, and a preset safety interval is reserved between the lower end of the puncture part and the sealing film at the moment, so that the puncture part cannot puncture the sealing film in a non-working state. The reagent is stored in the reservoir, and when it is desired to inject the reagent into the sample in the specimen cup, the pressing portion is pushed downward, at which time the sharp portion pierces the sealing membrane, thereby mixing the reagent with the sample. Furthermore, the cup body is transparent, so that the appearance characteristics of the color, the volume and the like of the sample in the cup can be directly observed, and meanwhile, the mixing state, the reaction progress and the like of the reagent and the sample can be monitored in real time. Further, scale marks are arranged on the side wall of the cup body along the height direction of the cup body, so that the volume of a sample in the cup body can be visually displayed. The method is convenient for accurately judging and controlling the sample collection amount, thereby ensuring that the collected sample amount meets the detection requirement and further avoiding influencing the accuracy of the detection result due to the abnormal sample amount. Further, a circle of sealing flange is arranged on the outer side wall of the cup body and is contacted with the lower end of the cup cover, so that the tightness of the cup cover after the cup cover is covered is improved, and the risk of sample leakage is reduced. Furthermore, a sealing ring is arranged at the bottom of the cup cover. So as to improve the tightness of the cup cover after the cup cover is covered and reduce the risk of sample leakage. Further, the liquid storage tanks are arranged at intervals, and the number of the pressing parts is matched with that of the liquid storage
