Description

Technical Field

[0001] This utility model relates to the field of medical testing, specifically a mixed specimen cup for sample collection. Background Technology

[0002] During sample collection and processing, especially when handling infectious biological samples (such as sputum, urine, feces, and other bodily fluid samples), it is usually necessary to add specific processing reagents after sample collection to maintain sample viability, inhibit microbial growth, delay sample putrefaction, and pretreat the samples. However, currently, the mixing of biological samples and reagents mainly employs methods such as the open-liquid addition method, the double-layer container method, and the premixing method, all of which have shortcomings.

[0003] Open-liquid addition method: This method requires the operator to manually open the specimen cup lid and add reagents. This process is not only cumbersome, but also carries the risk of sample spillage, posing a high risk of infection and a threat to the biosafety of the operator. Furthermore, the sample is easily contaminated by external environmental factors, affecting the accuracy of subsequent test results.

[0004] Double-container method: This method uses two separate containers to hold the sample and reagent respectively. Although it avoids direct contact between the sample and reagent to some extent, the operation is complicated and the use of two containers increases the cost.

[0005] Premixing: This method involves pre-mixing reagents into the specimen cup used for sampling. While this simplifies the process, prolonged contact between the reagents and the sample can affect the accuracy and timeliness of the sample, especially when handling time-sensitive samples such as viral samples, where premixing may lead to reduced sample activity.

[0006] In summary, existing specimen cup technology has shortcomings in terms of biosafety, sample quality assurance, and ease of operation, all of which urgently need improvement. Utility Model Content

[0007] The purpose of this invention is to address the above-mentioned problems by providing a mixed specimen cup for sample collection, which can improve biosafety and ease of operation during collection, and effectively reduce the risk of sample contamination or quality damage.

[0008] To achieve the above objectives, the present invention employs a mixed specimen cup for sample collection. It includes a cup body and a lid adapted to the open end of the cup body. The lid has a liquid storage chamber extending into the cup body. The lower end of the liquid storage chamber is open and sealed by a sealing membrane. A puncture part is provided inside the liquid storage chamber, with a sharp point at its lower end. The upper end of the puncture part is connected to a pressing part, which is located on the lid. When the pressing part is not subjected to external force, it will not shift. Furthermore, a pre-set safety gap exists between the lower end of the puncture part and the sealing membrane, ensuring that the puncture part will not puncture the sealing membrane when not in use. Reagents are stored in the liquid storage chamber. When reagents need to be injected into the sample in the specimen cup, the pressing part is pressed down. The sharp point punctures the sealing membrane, thus mixing the reagents with the sample.

[0009] Furthermore, the cup is transparent, making it easy to directly observe the appearance characteristics of the sample inside, such as color and volume, while also allowing for real-time monitoring of the mixing state of the reagent and sample, as well as the reaction process.

[0010] Furthermore, the cup body has graduations along its height on its side wall, which visually displays the volume of the sample inside the cup. This facilitates accurate judgment and control of the sample collection volume, ensuring that the collected sample volume meets the testing requirements and thus avoiding the impact of abnormal sample volume on the accuracy of the test results.

[0011] Furthermore, a sealing flange is provided on the outer wall of the cup body, which contacts the lower end of the cup lid to improve the sealing performance after the cup lid is closed and reduce the risk of sample leakage.

[0012] Furthermore, a sealing ring is provided at the bottom of the cup lid to improve the seal when the lid is closed and reduce the risk of sample leakage.

[0013] Furthermore, the liquid storage chambers are spaced out, and the number of press points corresponds to the number of storage chambers. The spaced-out arrangement of the storage chambers allows for the separate storage of different reagents, ensuring each reagent has its own independent space and preventing mutual interference and confusion. The number of press points corresponds to the number of storage chambers, allowing each reagent to be released through a specific press point. Operators can select to press a specific press point according to actual needs to release the corresponding reagent, thereby achieving the orderly addition of multiple reagents, improving work efficiency and operational flexibility.

[0014] Furthermore, a label is provided on the outer side of the pressing part. The label can clearly indicate the reagent type corresponding to each pressing part, enabling operators to quickly and accurately identify and press the corresponding part, avoiding misoperation and ensuring accurate reagent release.

[0015] The beneficial effects of this invention are as follows: The required reagents are pre-sealed in the storage chamber. When sample and reagent mixing is required, the reagents are introduced into the container by puncturing the sealing membrane, thus achieving sample and reagent mixing in a closed environment. This design allows reagent addition and mixing to be completed without opening the lid, simplifying the operation process and effectively avoiding the risk of sample leakage, thereby significantly reducing biosafety risks and the risk of infection for operators. Simultaneously, it allows for precise control of the mixing reaction time, avoiding impact on sample accuracy and timeliness, and improving sample processing quality. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0020] Example 1, such as Figure 1 As shown, the structure of this embodiment is as follows: a mixed specimen cup for sample collection, which includes a cup body 1 and a cup lid 2 adapted to the open end of the cup body 1. The cup lid 2 and the cup body 1 can be connected by snap-fit, thread, etc. In this embodiment, a threaded connection is used. For this purpose, an external thread is provided on the upper part of the side wall of the cup body 1, and an internal thread adapted to the external thread is provided on the inner side wall of the cup lid 2. The thread can adopt a double helix structure. The cup body 1 can be made of medical grade transparent PP material. The cup body 1 is preferably cylindrical. The side wall of the cup body 1 is provided with a scale line 7 along its depth direction, and the value gradually increases from bottom to top. A sealing flange 8 concentric with it is provided on the outer side wall of the cup body 1.

[0021] The cup lid 2 is provided with a liquid storage chamber 3 extending into the cup body 1. The liquid storage chamber 3 and the cup lid 2 can be integrally molded. The lower end of the liquid storage chamber 3 is open and sealed by a sealing film 4. The sealing film 4 can be an aluminum foil composite film. Polyethylene covers one side of the sealing film of the liquid storage chamber 3. The thickness of the sealing film 4 can be 0.1 mm, or selected as needed. The sealing film 4 is fixed to the lower end of the liquid storage chamber 3 by existing heat sealing processes. A puncture part 5 is provided inside the liquid storage chamber 3. The lower end of the puncture part 5 is provided with a sharp point. The upper end of the puncture part 5 is connected to a pressing part 6. The pressing part 6 is provided on the cup lid 2. The pressing part 6 can be made of medical-grade TPE material with a hardness of 60 degrees. To install the pressing part 6, a through hole can be opened at the top of the cup lid 2. The outer wall of the pressing part 6 is connected to the inner wall of the through hole by a process such as two-color injection molding. A sealing ring 9 is provided at the bottom of the cup lid 2. The sealing ring 9 can be made of rubber, etc.

[0022] When there is more than one type of reagent, the liquid storage chambers 3 are spaced apart, and the number of pressing parts 6 is adapted to the liquid storage chambers 3. The pressing parts 6 are marked on the outside, and the types of markings include, but are not limited to, different numbers, letters and colors.

[0023] Specific mixing process: Before sampling, observe for any reagent leakage. After confirming there is no leakage, remove the lid 2 from the cup body 1, add the sample into the cup body 1, and then replace the lid 2 back onto the cup body 1. At this time, the upper end of the cup body 1 abuts against the sealing ring 9, and the lower end of the lid 2 abuts against the sealing flange 8. When it is necessary to mix the reagent with the sample, press down on the pressing part 6 to pierce the sealing membrane 4 with the sharp point, thereby allowing the reagent in the storage chamber 3 to enter the cup body 1 and mix with the sample. After mixing, store and transport the specimen cup upright.
