Description

Technical Field

[0001] The utility model relates to the technical field of sputum culture collection, in particular to a closed sputum culture collector. Background Technique

[0002] Sputum culture is one of the important means for diagnosing respiratory tract infections. Through sputum culture, it is possible to detect whether there are bacteria in the sputum, and determine the types and quantities of the bacteria, so as to guide clinicians to carry out targeted treatment;

[0003] It is found that the publication (announcement) number: CN214761196U discloses a closed sputum culture collector. In this technology, it is disclosed that "a closed sputum culture collector includes a container body and a cover body connected to the opening of the container body. A limiting groove is provided on the cover body, and a first through hole is provided on the limiting groove. The limiting groove is slidably connected with a sputum suction assembly. The sputum suction assembly includes a first baffle and a suction pipe. A second through hole corresponding to the first through hole is provided on the first baffle. The suction pipe is installed on the first baffle and corresponds to the second through hole. One side of the first baffle is connected to a second baffle through a connecting rod. When the secretion of the patient is sucked up, the second baffle is pushed into the limiting groove by finger, and at the same time, the first baffle is pushed to completely cover the first through hole. At this time, the first baffle is pushed away from the cover body. Finally, the connecting rod is manually broken to separate the first baffle from the second baffle, that is, the first baffle is separated from the cover body. Because the suction pipe is installed on the first baffle, the suction pipe is also separated from the cover body at the same time, and the closing can be completed";

The inner diameter of the bottom ring 10 is smaller than the bottom cross-sectional diameter of the collector body 3, and the outer diameter of the bottom ring 10 matches the inner diameter of the hollow ring 5.

[0035] In this embodiment: The collector body 3 can stand inside the hollow ring 5 without any fixation under the restriction of the hollow ring 5, facilitating the medical staff to replace the collector body 3.

[0036] In an alternative embodiment: The number of the threaded fixing plates 6 is two, and the threaded fixing plates 6 are distributed at the left and right ends outside the hollow ring 5. The length of the threaded rod 7 is 1.5 times the sum of the height of the weight block 13 and the length of the connecting rope 12.

[0037] In this embodiment: The suction cup 9 can adsorb on a flat surface, enhancing the stability of the sputum culture collector, avoiding tipping or shaking, and ensuring the safety of sputum collection.

[0041] In this embodiment: The collector body 3 is provided with the function of adjusting the angle under the fixation of the suction cup 9, facilitating medical staff to observe the sputum situation inside the collector body 3.

[0042] In an alternative embodiment: The overall shape of the weight block 13 is cylindrical, and the weight of the weight block 13 is twice the total weight of the water filled in the collector body 3.

[0043] In this embodiment: The collector body 3 can be kept balanced, avoiding the situation where medical staff forget to return the position after rotating the angle of the suction device 1, preventing sputum from overflowing, and reducing the risk of cross-infection.

[0044] Working principle and usage process of the utility model: Insert the sputum aspirator 1 into the socket, and insert the air delivery tube 2 extending from the bottom of the sputum aspirator 1 into the air hole on the left side of the top of the collector body 3. Connect the sputum delivery tube 4 to the infusion hole on the right side of the top of the collector body 3. After the collector body 3 is connected, take out the hollow ring 5, suck the suction cups 9 on the left and right sides of the bottom of the hollow ring 5 onto the tabletop of the hospital table. Then insert the bottom of the collector body 3 into the hollow ring 5 until the bottom of the collector body 3 touches the bottom ring 10 located below the inner side of the hollow ring 5. At this time, the weight block 13 connected to the collector body 3 by the connecting rope 12 also touches the tabletop. At this time, it is necessary to rotate the torsion plate 8 so that the weight block 13 is pulled by the connecting rope 12 and suspended. The torsion plate 8 drives the threaded rod 7 to rotate in the threaded fixing plate 6. The end of the threaded rod 7 away from the torsion plate 8 rotates on the top of the suction cup 9. At this time, the internal thread on the inner wall of the threaded fixing plate 6 and the external thread on the outer side of the threaded rod 7 are helically engaged with each other. The position of the threaded rod 7 remains unchanged, and the threaded fixing plate 6 drives the hollow ring 5 and the collector body 3 to move upward until the weight block 13 is suspended and then stops. The patient can concentrate the sputum in the collector body 3 through the sputum delivery tube 4. When the medical staff needs to observe the sputum in the collector body 3, the angle of the collector body 3 can be rotated. After the angle of the hollow ring 5 and the collector body 3 is rotated, the rotating shaft 11 connected to the hollow ring 5 and the threaded fixing plate 6 and the damping layer 14 on the outer side of the rotating shaft 11 also start to rotate. After the observation is completed, the collector body 3 returns to the vertical initial position under the action of the weight block 13.
