DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figure 1-Figure 7 A portable sputum suction device comprises a sputum suction device body 1 and a collecting cup 2 installed below the sputum suction device body 1, one end of the sputum suction device body 1 close to the collecting cup 2 is fixedly connected and communicated with an extension tube 3, the bottom surface of the extension tube 3 is connected with a flow stop component, the other end of the flow stop component is connected with a hose 6, the other end of the hose 6 is connected with a disinfection cup 7, the upper end of the disinfection cup 7 is connected to the lower end of the collecting cup 2, and the side of the extension tube 3 away from the sputum suction device body 1 is connected with a rubber septum 8.

[0026] The portable sputum suction device in the utility model is similar in structure to the existing portable sputum suction devices, such as the portable sputum suction device disclosed in the patent with publication number CN219941395U. The main improvement of the utility model is that after the user uses the sputum suction device body 1 outdoors, the inner wall of the sputum suction device body 1 can be rinsed and disinfected through the hose 6 and the disinfection cup 7, thereby avoiding cross infection when the sputum suction device body 1 is used for the second time. Figures 1 to 7 As shown, before the portable sputum suction device of the utility model is used outdoors, first add an appropriate amount of disinfectant water or cleaning liquid into the disinfection cup 7. When the patient uses the sputum suction device body 1 for the first time outdoors, insert one end of the disposable sputum suction tube through the rubber septum 8 into the extension tube 3, close the flow-stop component, and then use it according to normal steps; after use, pull the disposable sputum suction tube out of the extension tube 3. At this time, a part of sputum or other throat secretions will inevitably remain on the inner walls of the extension tube 3 and the sputum suction device body 1. At this time, open the flow-stop component, and start extracting again through the handle at the rear of the sputum suction device body 1. During the extraction process, because one end of the extension tube 3 is sealed by the rubber septum 8, it will flow along the flow-stop component and the hose 6 , the disinfectant is extracted from the disinfection cup 7, and the extracted disinfectant passes through the extension tube 3 and the inner wall of the sputum suction device body 1 and flows into the collection cup 2 again, so that the sputum or throat secretions remaining in the extension tube 3 and the sputum suction device body 1 can be washed into the collection cup 2, thereby avoiding cross infection of patients during subsequent use; and when the patient is outdoors for the second time, because the sputum or throat secretions remaining in the extension tube 3 and the sputum suction device body 1 have been washed away, and because a one-way valve is provided at the connection between the collection cup 2 and the sputum suction device body 1 (this is the prior art, so it is not described in detail), the sputum or throat secretions in the collection cup 2 will not flow into the extension tube 3 and the sputum suction device body 1, so the risk of cross infection of patients can be reduced.

[0027] Please refer to Figure 1-Figure 6 The flow stop assembly includes an outer ball 4, an inner ball 11 and a twist knob 5. The inner wall of the outer ball 4 is provided with a ball cavity 401. The inner wall of the inner ball 11 is penetrated with a through hole 1101. The upper end of the outer wall of the outer ball 4 is fixedly connected and communicated with the suction device body 1. The lower end of the outer wall of the outer ball 4 is communicated with the hose 6. The outer wall of the inner ball 11 is slidably connected with the inner wall of the ball cavity 401. One end of the twist knob 5 is fixedly connected with the outer wall of the inner ball 11. The other end of the twist knob 5 penetrates the inner wall of the ball cavity 401. The through hole 1101 is communicated with the suction device body 1 and the hose 6.

[0028] More specifically, when the extension tube 3 and the suction device body 1 are used for the first time, the knob 5 is turned, and the force applied to the knob 5 will drive the inner ball 11 to rotate in the ball cavity 401 until the through hole 1101 of the inner ball 11 is misaligned with the through holes at the upper and lower ends of the outer ball 4. At this time, the sputum sucked from the disposable suction tube in the extension tube 3 will be blocked by the inner ball 11 and will not flow into the hose 6 below, and can only enter the collection cup 2 for collection.

[0029] When the extension tube 3 and the inside of the sputum suction device body 1 need to be rinsed and disinfected after use, the knob 5 is turned to align the through hole 1101 of the inner ball 11 with the outer ball 4 so that disinfectant can be extracted from the disinfection cup 7 through the hose 6 during the extraction process of the sputum suction device body 1.

[0030] Please refer to Figure 3 The outer wall of the outer ball 4 is fixedly connected to two limit blocks 10, and the outer wall of one end of the twist 5 that passes through the ball cavity 401 is fixedly connected to a stop block 12, which is located between the two limit blocks 10, and the two sides of the stop block 12 are respectively abutted against the two limit blocks 10.

[0031] More specifically, by setting the limit block 10 and the stop block 12, the rotation direction and angle of the knob 5 can be limited so that the inner ball 11 can only rotate at a specific angle, thereby preventing the patient from rotating too much, resulting in the through hole 1101 being connected to the extension tube 3 during suction, which will not only affect the suction effect, but may also cause the sucked sputum to flow into the hose 6 and the disinfection cup 7, causing contamination.

[0032] The two ends of the hose 6 are respectively threadedly connected to the outer ball 4 and the disinfection cup 7. Through the threaded connection, the hose 6 can be easily disassembled and replaced when not in use or damaged. It should be particularly noted here that a one-way valve is provided at the connection between the hose 6 and the outer ball 4 and the disinfection cup 7, so that the disinfectant in the disinfection cup 7 can only flow into the hose 6, and vice versa, the liquid in the hose 6 cannot flow into the disinfection cup 7.

[0033] Please refer to Figure 4 and Figure 7 The bottom surface of the disinfection cup 7 is provided with a liquid inlet and outlet 701, and the inner wall of the liquid inlet and outlet 701 is threadedly connected with a sealing plug 9. By providing the liquid inlet and outlet 701 and the sealing plug 9, firstly, disinfectant can be added or discharged into the disinfection cup 7 through the liquid inlet and outlet 701; secondly, by means of threaded connection, it is more convenient to open when preparing to add or discharge disinfectant. It should be particularly noted here that a sealing gasket is provided at the connection between the sealing plug 9 and the liquid inlet and outlet 701 to prevent the disinfectant from flowing out.

[0034] The inner wall of the upper end of the disinfection cup 7 is threadedly connected to the outer wall of the lower end of the collection cup 2. Through the threaded connection, firstly, the connectivity between the disinfection cup 7 and the collection cup 2 can be increased, so that the disinfection cup 7 will not shake during use; secondly, when it is necessary to separate the disinfection cup 7 from the collection cup 2, it is also more convenient to operate. It should be specially noted here that: the end of the disinfection cup 7 close to the collection cup 2 can also be set as an opening, so that when adding and discharging disinfectant, the disinfection cup 7 can be separated from the collection cup 2 and discharged from this opening. This method has the same effect as the above-mentioned inlet and outlet 701 and the sealing plug 9, and is not specifically limited.

[0035] Please refer to Figure 5 and Figure 6 A connecting hole 801 is provided through the center of the rubber septum 8. By providing the connecting hole 801, it is more convenient to push open the rubber septum 8 when the external disposable suction tube is inserted, and after being pushed open, the friction between the rubber septum 8 and the disposable suction tube can be increased. It should be noted here that the connecting hole 801 has a very small aperture, and no external dust, debris, etc. will enter during normal sealing or during the flushing and disinfection stage (the effect is similar to the rubber sealing pad at the mouth of the infusion bottle).

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
