Description

Technical Field

[0001] This utility model relates to the field of sputum cup technology, and in particular to a disposable sterile sputum cup. Background Technology

[0002] A sputum cup is a medical device primarily used to collect and temporarily store a patient's sputum, saliva, or other bodily fluids.

[0003] However, traditional sputum cups still have certain drawbacks. For example, during spitting, most patients spit phlegm all over the cup. Then, when moving the cup, it shakes or even tipes over, causing the phlegm to spill out and stick to the lid. So when the cup is opened, the phlegm sticks firmly to the lid at one end and to the cup wall at the other. This causes the phlegm to be stretched into long strands when the lid is opened, which may cause some of the phlegm to drip onto the work surface, contaminating it. Even if it doesn't drip, the operator needs to hold the cup in one hand and the lid, which is stuck to the cup with the phlegm strands, in the other, making it impossible to use one hand to collect the specimen, which greatly affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a disposable sterile sputum cup that does not require opening the cup lid after the patient has coughed up sputum and closed the lid, until the test is completed. Only the soft rubber protective cover needs to be opened. This avoids the biosafety problem of sputum sticking to the lid of the traditional sputum cup and causing the specimen to drip onto the operating table and contaminate the environment, as well as the problem of not being able to pull out the sputum and making it difficult to collect samples.

The spiral soft plastic cup 1 is connected to the hollow tube 3, the hollow tube 3 is connected to the plastic inoculation ring 4, and the plastic inoculation ring 4 is connected to the connecting tube 5.

[0030] A sliding rod 9 is movably connected to the inner surface of the top cover holder 6. A fixing plate 10 is fixedly connected to the lower end of the sliding rod 9. A first limiting ring 11 is fixedly connected to the outer surface of the sliding rod 9. The first limiting ring 11 can limit the movement range of the sliding rod 9. A first spring 12 is fixedly connected to the upper surface of the fixing plate 10. An L-shaped connecting plate 13 is fixedly connected to the outer surface of the top cover holder 6. A connecting rod 14 is slidably connected to the inner surface of the L-shaped connecting plate 13. A pull ball 15 is fixedly connected to one end of the connecting rod 14, and a second limiting ring 16 is fixedly connected to the other end of the connecting rod 14. The side surface of the second limiting ring 16 is fixedly connected to the first spring 12. The inclined insert 17 is fixedly connected, and the outer surface of the connecting rod 14 is provided with a second spring 18. The outer surface of the slide rod 9 is slidably connected to the top cover seat 6, and the upper end of the slide rod 9 is in contact with the soft rubber protective cover 8. The end of the first spring 12 away from the fixed plate 10 is fixedly connected to the top cover seat 6. The outer surface of the top cover seat 6 is in contact with the second limiting ring 16. The outer surface of the inclined insert 17 is slidably connected to the top cover seat 6. One end of the second spring 18 is fixedly connected to the L-shaped connecting plate 13, and the other end of the second spring 18 is fixedly connected to the second limiting ring 16. The inner surface of the inclined insertion hole 20 is adapted to the inclined insert 17.

[0031] Working principle: In use, the cup lid 2 is unscrewed using the threaded wire 19. The patient then spits sputum into the spiral soft plastic cup 1 and tightens it again to seal the cup. The sputum cup is then moved near the slide, and the pull ball 15 is pulled outwards, causing the connecting rod 14 to disengage the inclined insert 17 from the inclined insertion hole 20, thus releasing the restriction on the soft protective cover 8. Under the action of the second limiting ring 16, the second spring 18 is compressed. At this time, under the rebound force of the first spring 12 in a stretched state, the sliding rod 9 is pushed upwards through the fixing plate 10. With the cooperation of the first limiting ring 11, the soft protective cover 8, now freed from restriction, is pushed upwards to a certain height. The soft protective cover 8 can then be pulled out along the inside of the slot 7 to complete the opening operation. This is simple and convenient. Finally, the connecting tube 5 is placed on the slide. The spiral soft plastic cup 1 is squeezed, thereby changing the volume of the sputum inside the cup and squeezing it onto the glass slide through the hollow tube 3, plastic inoculation ring 4, and connecting tube 5 in sequence, so as to facilitate subsequent testing. This avoids the inconvenience of having to open the cup lid 2 to remove the sputum inside the spiral soft plastic cup 1. After the test, simply reinsert the soft rubber protective cover 8 into the slot 7 and press it down. Under the action of the inclined surface of the inclined insert 17, the inclined insert 17 moves outward and compresses the second spring 18. At the same time, the slide rod 9 is squeezed, and the first limiting ring 11 is stretched. When the inclined insert 17 corresponds to the inclined insertion hole 20, under the restoring force of the second spring 18, the inclined insert 17 will automatically lock into the inclined insertion hole 20, thereby completing the limiting and fixing of the soft rubber protective cover 8 and preventing it from falling off during the movement.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
