Description

Technical Field

[0001] This invention relates to the field of lung-clearing and sputum-expelling technology, specifically to a lung-clearing and sputum-expelling device for respiratory medicine. Background Technology

[0002] Internal medicine, a branch of medicine, is further divided into various specialties based on different systems, such as respiratory medicine, cardiovascular medicine, gastroenterology, nephrology, hematology, endocrinology and metabolic diseases, and rheumatology. It also includes infectious diseases, psychiatry, and neurology. Internal medicine is a comprehensive discipline in clinical medicine, with a broad scope and strong holistic approach, studying the etiology, diagnosis, and prevention of diseases in various systems and organs of the human body. Respiratory medicine is a branch of medicine that specifically treats diseases related to the respiratory system. Sputum is a fluid secreted by the respiratory tract when stimulated, also called phlegm. Its components include mucus, foreign bodies, pathogenic microorganisms, various inflammatory cells, and necrotic sloughed mucosal epithelial cells. With severe air pollution, respiratory inflammation is easily caused, and the accumulation of phlegm in the respiratory tract can obstruct breathing. Normally, phlegm is expelled by coughing, but for sick people, this phlegm cannot be expelled in time, thus blocking the trachea, affecting the respiratory system, and in severe cases, causing suffocation and death. Therefore, doctors need to use external tools to clear the phlegm from the patient's respiratory tract.

[0003] In existing technologies, common negative pressure suction devices store sputum directly in a collection bottle after suctioning. The sputum may contain bacteria, viruses, or other pathogenic microorganisms. Since the collection bottle is under negative pressure during suction, these bacteria will be drawn into the negative pressure generating device and then discharged into the external environment through the negative pressure device. This may spread to other patients or medical personnel, causing cross-infection and increasing the risk of nosocomial infection. Therefore, this invention proposes a lung-clearing and sputum-expelling device for respiratory medicine. Summary of the Invention

[0004] The purpose of this invention is to provide a respiratory medicine lung-clearing and sputum-expelling device to solve the problem mentioned in the background art that, after the sputum is suctioned, it is directly stored in the sputum collection bottle. The sputum may contain bacteria, viruses or other pathogenic microorganisms. Since the sputum collection bottle is under negative pressure when suctioning sputum, these bacteria will be sucked into the negative pressure generating device along with the negative pressure, and then discharged into the external environment through the negative pressure device. This may spread to other patients or medical personnel, causing cross-infection and increasing the risk of nosocomial infection.

An external water pump 1502 is fixedly connected to the rear side of the flushing fluid storage bottle 1501. The input end of the external water pump 1502 is connected to the inside of the flushing fluid storage bottle 1501 through a pipe. The filling port 1503 facilitates the injection of flushing fluid, and the sealing cap above can prevent the flushing fluid from being contaminated. The external water pump 1502 on the rear side of the upper part is connected to the inside of the flushing fluid storage bottle 1501 through a pipe, which can provide stable power to deliver flushing fluid to the suction tube 707, realize the flushing of the inside of the tube, and reduce hygiene dead corners.

[0044] In one embodiment of the present invention, the backflushing assembly 15 further includes a diverter 1505. The diverter 1505 has a first channel 1506 laterally opened inside, and a second channel 1507 is opened in the upper middle part of the diverter 1505. The first channel 1506 and the second channel 1507 are interconnected. This integrated channel design makes the diverter 1505 compact in structure, and can simultaneously realize the functions of negative pressure transmission and backflushing fluid delivery, simplifying pipeline connection, reducing leakage risk, and improving the integration and reliability of the device.

[0045] In one embodiment of the present invention, a first connector 1508 is fixedly connected above the diverter 1505 at the position of the second channel 1507. A liquid delivery pipe 1504 is sleeved on the outside of the first connector 1508, and the end of the liquid delivery pipe 1504 is fixedly connected to the output end of the external water pump 1502. A second connector 1509 is fixedly connected to the right end of the first channel 1506 on the right side of the diverter 1505.

The upper part is detachable. The left side of the diverter 1505 is fixedly connected to the left end of the first channel 1506. The outer side of the third connector 1511 is sleeved with the second negative pressure tube 1512. The end of the second negative pressure tube 1512 is connected to the negative pressure mechanism 14 through a connector. The detachable connection of each connector and pipe facilitates installation, maintenance and replacement. This pipeline layout allows the negative pressure system and the backflushing system to be connected in an orderly manner through the diverter 1505, ensuring precise coordination of suction and backflushing actions and improving the synergy of the device.

[0046] In one embodiment of the present invention, a wedge-shaped blocking block 1513 is slidably connected inside the second channel 1507. A sealing gasket 1514 is fixedly connected to the bottom of the blocking block 1513. A connecting rod 1515 is fixedly connected to the middle of the bottom surface of the blocking block 1513. The lower end of the connecting rod 1515 passes through the bottom surface of the diverter 1505 and is fixedly connected to a fixing block 1516. The fixing block 1516 has snap-fit ​​notches 1517 on both the left and right sides above it. The slidably connected wedge-shaped blocking block 1513, together with the bottom sealing gasket 1514, can effectively seal the channel and prevent backflushing liquid from flowing into the negative pressure airway. The blocking block 1513 is connected to the fixing block 1516 by the connecting rod 1515 through the snap-fit ​​notches 1517 above it, which facilitates the fixing of the blocking block 1513 and realizes the precise switching between the first channel 1506 and the second channel 1507. This ensures smooth negative pressure during suctioning and smooth liquid delivery during backflushing, improving the accuracy of operation.

[0047] In one embodiment of the present invention, rotating seats 1519 are fixedly connected to the bottom surface of the diverter 1505 on both the left and right sides of the connecting rod 1515. A clamping rod 1520 is rotatably connected inside each of the two rotating seats 1519. A return spring 1518 is sleeved on the outside of the connecting rod 1515. The upper end of the return spring 1518 is fixedly connected to the bottom surface of the diverter 1505, and the lower end of the return spring 1518 is fixedly connected to the top of the fixing block 1516. The return spring 1518 sleeved on the outside of the connecting rod 1515 can automatically drive the sealing block 1513 to reset when the clamping rod 1520 is released, ensuring convenient and stable channel switching and improving the flexibility and reliability of device operation.

[0048] When using this device, push the handle 5 to move it to the patient's bedside via the universal casters 3 under the crossbeam 2; adjust the height of the scissor lift 1 to match the height of the suction assembly 7 with the patient's airway (e.g., adjust to chest level for supine patients), ensuring a comfortable angle when the suction tube 707 is inserted to avoid airway traction; remove the sterile suction tube 707 from the storage box 4, attach it to the insertion tube 705, and press it firmly to seal using the pressing plate 706; insert the sputum collection bottle 701 into the snap-fit ​​sleeve 6, and tighten the bottle cap 702 with the sealing ring 703 to ensure the sputum collection bottle 701 is securely sealed. 1. Seal to prevent negative pressure leakage; inject disinfectant 711 into the sputum collection bottle 701, the liquid level should be 5-10mm above the lower end of the first connecting tube 704, open the sealing cap of the filling port 1503 of the rinsing solution storage bottle 1501, inject physiological saline (or special rinsing solution), and close the sealing cap; connect the power supply of the display and control device 9 and the negative pressure mechanism 14, start the equipment self-test, and ensure that the miniature camera 12, the supplementary light ring 13 and the negative pressure are normal, attach the miniature camera 12 at the end of the wire 10 to the end of the suction tube 707 and temporarily fix it with the retaining ring 11, then start... The auxiliary light ring 13 is used to slowly insert the suction tube 707 into the patient's airway. Medical staff observe the airway through the display and control device 9, locate the location of sputum accumulation, and fine-tune the depth and angle of the suction tube 707 according to the display screen, so that the second suction hole 713 at the end of the suction tube 707 and the first suction hole 708 on the side are aligned with the sputum, avoiding the suction holes from adhering to the airway mucosa. The negative pressure mechanism 14 is activated, and the negative pressure is transmitted through the second negative pressure tube 1512 to the first channel 1506 of the diversion component 1505, and then through the first negative pressure tube 1510, the filter 710, and the second connecting tube. 709 enters above the liquid surface of the sputum collection bottle 701, creating a stable negative pressure inside the sputum collection bottle 701. Under the action of negative pressure, sputum in the airway is sucked into the suction tube 707 through the first suction hole 708 and the second suction hole 713, and then directly discharged into the disinfectant solution 711 of the sputum collection bottle 701 through the insertion tube 705 and the first connecting tube 704. The sputum is immediately soaked and inactivated by the disinfectant solution 711 to prevent the spread of bacteria. A small amount of atomized sputum in the sputum collection bottle 701 (rising with the negative pressure) enters the filter element 710 through the second connecting tube 709. The internal microporous plate 712 can intercept ≥0.2μm bacteria and viruses are further blocked from entering the negative pressure mechanism 14, ensuring that the discharged air is uncontaminated. After the sputum is suctioned, the negative pressure mechanism 14 is closed, the contaminants inside the sputum collection bottle 701 are poured into the waste bin, and the bottle cap 702 is screwed back on. The connecting rod 1515 is pulled to lower the sealing block 1513, which seals the left end of the first channel 1506, cutting off the negative pressure path and connecting the right end of the first channel 1506 with the second channel 1507. Then, the locking rod 1520 is rotated so that the end of the locking rod 1520 is engaged in the locking notch 1517. Next, the end of the suction tube 707 is aligned with the inside of the waste bin, and the external water pump 1502 is started. The flushing fluid in the flushing fluid storage bottle 1501 flows through the delivery pipe 1504 and the first connector 150. The 8-channel fluid enters the second channel 1507 of the diversion component 1505, then flows into the first channel 1506, and is reverse-flushed into the sputum collection bottle 701 via the first negative pressure pipe 1510 and the filter element 710. As the flushing fluid is injected, it flushes the inside of the first connecting pipe 704. The flushed wastewater is discharged into the waste bin through the suction pipe 707. After flushing, the two locking rods 1520 on the bottom of the diversion component 1505 are rotated to disengage them from the locking notch 1517 of the fixing block 1516; the return spring 1518 springs upward, causing the connecting rod 1515 and the sealing block 1513 to rise, opening the first channel 1506 and restoring the negative pressure suction state. After the internal flushing of the pipeline is complete, all components of the suction assembly 7 are sterilized with high-pressure steam, cooled, and reassembled for future use.
