Description

Technical Field

[0001] This utility model relates to a liquid collection device, specifically a sputum collection device, and belongs to the field of medical device technology. Background Technology

[0002] Patients with respiratory diseases produce a lot of sputum during their illness. The sputum needs to be coughed up from the mouth and collected to prevent the sputum from being accidentally coughed up and causing infection to medical staff and other patients. This reduces the damage to the air environment and the spread of viruses. The sputum is collected by a sputum collection device, which ensures the safety and effectiveness of the sputum collection process.

[0003] During hospitalization, patients are often weak and mostly lie down. Sputum collection devices are typically placed on the floor, usually on one side of the bed. When patients need to cough up sputum, they must sit up and tilt to the side to spit it into the collection device. Because the device is relatively far away, patients may not be able to accurately spit the sputum into it, and the sputum may end up outside the device, hindering effective collection. This necessitates subsequent cleaning by medical staff, increasing their workload and reducing the effectiveness of the collection device. Therefore, we have developed a sputum collection device to address these issues. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a sputum collection device, the specific technical solution of which is as follows: A sputum collection device includes a sleeve and a collection bucket. The collection bucket is located inside the sleeve. A slide is connected to the outer surface of the collection bucket. The outer surface of the slide is slidably connected to the inner wall of the sleeve. A toothed plate is connected to one side of the slide. A sliding sleeve is connected to the outer surface of the sleeve. A slider is slidably connected to the inner wall of the sliding sleeve. A spring is provided inside the sliding sleeve. A push rod is rotatably connected to the upper surface of the slider. A toothed plate is connected to one side of the slider. Gears are meshed on opposite sides of the toothed plate and the toothed plate.

[0005] Preferably, the inner bottom wall of the sliding sleeve is connected to a guide rod, the spring is sleeved on the outside of the guide rod, one end of the spring is connected to the inner bottom wall of the sliding sleeve, and the other end of the spring is connected to the inner bottom wall of the slider.

[0006] Preferably, the outer surface of the slider is connected to a positioning pin, the inner side of the sliding sleeve is provided with a slide rail, and the outer surface of the positioning pin is slidably connected to the inner wall of the slide rail.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This sputum collection device utilizes the interaction between toothed plate one, toothed plate two, gears, and a push rod. By pushing the push rod, a driving force is generated, which moves the slider. Simultaneously, the slider moves toothed plate two, which transmits power to toothed plate one via gears, causing toothed plate one to move as well. By moving toothed plate one, the height of the collection container is changed, bringing it closer to the patient. This allows the patient to accurately spit sputum into the collection container, improving its collection efficiency and reducing the workload of medical staff.

[0012] 2. This sputum collection device works by rotating a push rod while simultaneously rotating a stop rod. The stop rod contacts the slot, causing the cover to rotate and opening the inlet and outlet of the collection bin. The cover receives the pushing force of the stop rod through the slot inside the cover, thus enabling the cover to move. The cover closes and opens the inlet and outlet of the collection bin, reducing the evaporation of sputum and improving the safety of the collection bin during use. Attached Figure Description

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] Please see Figures 1-5 A sputum collection device includes a sleeve 1 and a collection bucket 2. The collection bucket 2 is located inside the sleeve 1 and has a cavity inside, through which sputum is collected.

[0017] The outer surface of the collection bucket 2 is connected to a slide block 3. The outer surface of the slide block 3 is slidably connected to the inner wall of the sleeve 1. The collection bucket 2 contacts the sleeve 1 through the slide block 3, maintaining the stability of the collection bucket 2 when it moves up and down.

[0018] A toothed plate 4 is connected to one side of the slide block 3, and a sliding sleeve 5 is connected to the outer surface of the sleeve 1. A slider 6 is slidably connected to the inner wall of the sliding sleeve 5. A spring 7 is provided inside the sliding sleeve 5. The sliding sleeve 5 provides support force to the slider 6 to maintain the stability of the slider 6 when it moves. The spring 7 provides pushing force to the slider 6 to push the slider 6 to move upward and reset the slider 6.

[0019] A push rod 8 is rotatably connected to the upper surface of the slider 6. The push rod 8 is positioned high to facilitate contact between the patient and the push rod 8. The patient pushes the push rod 8 to move downwards. After the push rod 8 moves downwards, it applies pressure to the slider 6, pushing the slider 6 to move downwards. At the same time as the slider 6 moves downwards, the spring 7 is compressed. The compressed spring 7 provides power for the slider 6 to reset.

[0020] One side of the slider 6 is connected to a toothed plate 9. The opposite sides of the toothed plate 4 and the toothed plate 9 are meshed with a gear 10, which transmits power through the gear 10. When the slider 6 moves downward, it drives the toothed plate 9 to move downward at the same time. After the toothed plate 9 moves, it pushes the gear 10 to rotate. After the gear 10 rotates, it pushes the toothed plate 4 to move upward. The toothed plate 4 pushes the collection bucket 2 to move upward through the slide block 3, so that the collection bucket 2 shortens the distance between itself and the patient.

[0021] A guide rod 11 is connected to the inner bottom wall of the sliding sleeve 5. A spring 7 is sleeved on the outside of the guide rod 11. One end of the spring 7 is connected to the inner bottom wall of the sliding sleeve 5, and the other end of the spring 7 is connected to the inner bottom wall of the slider 6. When the spring 7 repeatedly contracts and contracts, the spring 7 may deform. After the spring 7 is deformed, it will lose its support for the slider 6. The guide rod 11 provides support inside the spring 7 to prevent the spring 7 from deforming and improve the stability of the spring 7.

[0022] The outer surface of the slider 6 is connected to a positioning pin 12, and the inner side of the slide sleeve 5 is provided with a slide rail 13. The outer surface of the positioning pin 12 is slidably connected to the inner wall of the slide rail 13. The slide rail 13 guides the movement position and distance of the positioning pin 12, maintains the stability of the positioning pin 12, and limits the movement distance of the slider 6 to prevent the slider 6 from detaching from the slide sleeve 5.

[0023] A cover plate 14 is rotatably connected to the top of the collection bucket 2. A retaining plate 15 is connected to the upper surface of the cover plate 14. A retaining groove 16 is opened on the inner side of the retaining plate 15. The cover plate 14 seals the inlet and outlet of the collection bucket 2, reducing the evaporation of sputum to the outside. The cover plate 14 receives the pushing force of the stop rod 17 through the retaining groove 16 inside the retaining plate 15, thereby enabling the cover plate 14 to move. A stop rod 17 is connected to the outer surface of the push rod 8. One end of the stop rod 17 contacts the inner wall of the retaining groove 16. When the push rod 8 rotates, it drives the stop rod 17 to rotate simultaneously. The contact between the stop rod 17 and the retaining groove 16 drives the cover plate 14 to rotate. 4. After rotation, the inlet and outlet of the collection bucket 2 are opened, and the patient can spit the sputum into the inside. After the patient spits the sputum into the collection bucket 2, the push rod 8 is rotated in the opposite direction to move the stop rod 17 to a new position. At the same time as the stop rod 17 moves to a new position, the cover plate 14 is reset, thus closing the inlet and outlet of the collection bucket 2 to prevent the sputum from evaporating to the outside. The outer surface of the collection bucket 2 is connected to a baffle 18, and the baffle 18 is adapted to the cover plate 14. The height of the baffle 18 is higher than that of the collection bucket 2. The baffle 18 provides resistance to the cover plate 14, limiting the movement of the cover plate 14 and preventing the cover plate 14 from rotating too much and failing to cover the collection bucket 2.

[0024] The upper surface of the sliding sleeve 5 is connected to two bases 19, which are symmetrical. The inner wall of the base 19 is connected to a support shaft 20. The outer surface of the support shaft 20 is rotatably connected to the inner wall of the gear 10. The base 19 provides support for the support shaft 20 to maintain its stability. The support shaft 20 provides force to the gear 10 to maintain its stability during rotation.

[0025] In use, this invention works as follows: First, the hand contacts the push rod 8, pushing it downwards. Simultaneously, the push rod 8 pushes the slider 6 downwards, causing the second toothed plate 9 to move. The second toothed plate 9 drives the gear 10 to rotate, compressing the spring 7 as the slider 6 moves downwards. After the gear 10 rotates, it pushes the first toothed plate 4 upwards. Simultaneously, the first toothed plate 4 moves upwards via the slide block 3, causing the collection bucket 2 to move upwards. After the collection bucket 2 moves upwards, the distance between it and the patient is shortened. After the collection bucket 2 moves upwards, the slot 16 contacts the stop rod 17. Then, the push rod 8 is rotated, causing the stop rod 17 to move. The stop rod 17 moves via the locking plate 15, causing the cover plate 14 to move. The cover plate 14 then disengages from the collection bucket 2, opening the inlet and outlet of the collection bucket 2, allowing the patient to spit sputum into the collection bucket 2. After the patient finishes using the collection bucket 2, the collection bucket 2 is reset and covered using the same method.
