Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a contamination-proof container for collecting bodily fluid samples. Background Technology
[0002] Currently, the process for obtaining bodily fluid samples from patients who need to have their urine or semen tested at the hospital is generally as follows: first, the bodily fluid sample is placed in a collection cup, then the sample in the collection cup is placed into a collection tube, and finally the patient hands the collection tube over to the hospital for subsequent testing. Therefore, the collection cup, which comes into contact with the bodily fluid sample first, has a significant impact on the test results.
[0003] Collection cups are usually left unsealed on the counter at the laboratory window, and patients can pick them up and put them away at will. As a result, collection cups in such an environment are easily contaminated, which can affect the test results of the samples and cause unavoidable losses and trauma to patients.

[0030] Please see Figure 1-5The present invention provides a pollution-proof body fluid sample collection container, comprising a collection cup 1 and a top cover 3. The top of the collection cup 1 is provided with a collection sleeve 2, and the top cover 3 is fastened to the top of the collection sleeve 2 and is threadedly connected to the collection sleeve 2. The lower end of the collection cup 1 is provided with a drain pipe 4 and a bottom cap 5, and the bottom cap 5 is fastened to the drain pipe 4 and is threadedly connected to the drain pipe 4.
[0031] The top cover 3 has a hollow groove 6 in the middle part, and the drain pipe 4 can be inserted into the hollow groove 6.
[0032] The cavity 6 is provided with a toggle block 7. The lower end of the toggle block 7 is provided with a vertical rod 8 that penetrates the top cover 3, and the bottom end of the vertical rod 8 is provided with a pressure plate 10 located inside the collection cup 1.
[0033] In this embodiment, both the top cover 3 and the bottom cap 5 are provided with anti-slip textures on their periphery.
[0034] In this embodiment, the collection cup 1, the collection sleeve 2, and the drain pipe 4 are an integrated structure.
[0035] Sample collection principle: When collecting body fluid samples, the collection sleeve 2 at the top of the collection cup 1 enlarges the opening of the collection cup 1, making sample collection more convenient. Since the collection cup 1, collection sleeve 2, and drain tube 4 are integrated into one structure, overall sealing and stability are ensured. When collecting samples from a patient, the top cover 3 is opened, and the body fluid is collected in the collection cup 1. The top cover 3 and collection sleeve 2 are connected by threads, ensuring the cleanliness of the inside of the collection cup 1 before collection and preventing external contaminants from entering.
[0036] Sample transfer principle: When it is necessary to transfer the body fluid sample in collection cup 1 to a designated test tube, first remove the top cover 3. At this time, pull the actuating block 7 in the empty slot 6. Since the lower end of the actuating block 7 is connected to the vertical rod 8 that passes through the top cover 3, and the bottom end of the vertical rod 8 is connected to the pressure plate 10, the movement of the actuating block 7 will drive the pressure plate 10 to rise. After sampling is completed, close the top cover 3 and press the actuating block 7 again. The pressure plate 10 will move downward under the action of the vertical rod 8. Because the pressure plate 10 has a sealing ring on its periphery that contacts the inner wall of the collection cup 1, the liquid sample in the collection cup 1 can be stably pressed into the test tube through the drain tube 4. The drain tube 4 facilitates the sample transfer operation, and when not in use, the bottom cap 5 is fastened to the drain tube 4, and the two are threaded together to prevent sample leakage and external contamination.
[0037] In this embodiment, the bottom of the empty groove 6 is provided with a sealing block 9 that is penetrated by the vertical rod 8, and the periphery of the pressure plate 10 is provided with a sealing ring that contacts the inner wall of the collection cup 1.
[0038] In this embodiment, the bottom of the collection cup 1 is provided with a plurality of anti-slip strips located around the drain pipe 4.
[0039] Contamination prevention and stacking principle: When not in use, the top cover 3 is fastened to the collection sleeve 2, acting as a seal to effectively prevent external contaminants from entering the collection cup 1 and contaminating the sample. When stacking sample collection containers, the collection cup 1 is inverted, allowing the drain tube 4 to be inserted into the hollow groove 6 in the middle of the top cover 3, achieving stable stacking. The bottom of the hollow groove 6 is equipped with a sealing block 9 penetrated by the vertical rod 8, further ensuring the sealing of the vertical rod 8 and preventing external air and contaminants from entering the collection cup 1 through the gap between the vertical rod 8 and the hollow groove 6. At the same time, multiple anti-slip strips located around the drain tube 4 at the bottom of the collection cup 1 increase the friction between the collection cups 1, making multiple collection cups 1 more stable after stacking and less prone to slipping.
[0040] In this embodiment, the top cover 3 is provided with a plurality of cavities 11, a disinfection block 13 is placed in the cavity 11, and a sealing sheet 12 is provided on the top of the cavity 11. The sealing sheet 12 is adhered to the upper end of the top cover 3, and the disinfection block 13 is made of alcohol cotton.
[0041] Disinfection principle: Multiple cavities 11 on the top cover 3 contain alcohol swab disinfection blocks 13, and the sealing sheet 12 on the top of the cavity 11 is attached to the upper end of the top cover 3. Before use, if it is necessary to disinfect the collection cup 1 or related areas, the sealing sheet 12 can be opened, and the alcohol swabs can be taken out to wipe and disinfect the opening of the collection cup 1, the collection sleeve 2, or other areas that need to be disinfected. This improves the functionality of the entire sample collection container and reduces the risk of sample contamination.
[0042] The collecting cup 1, top cover 3, and bottom cap 5 are all made of polypropylene plastic.
[0043] The collection cup 1, top cap 3, and bottom cap 5 are all made of polypropylene plastic. This material has good chemical stability, corrosion resistance, and hygiene. It will not react chemically with body fluid samples, ensuring that the properties of the samples are not affected. It also meets the hygiene standards for medical devices and is safe and reliable.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
