Description

Technical Field

[0001] The utility model belongs to the technical field of sputum suction, in particular to a handheld sputum suction device. Background Art

[0002] With the continuous advancement of medical technology and the in-depth development of pediatric medicine, the diagnosis and treatment of children's respiratory diseases are facing more and more challenges. Among them, the accumulation of phlegm in the throat is a common clinical problem in pediatrics, which may cause symptoms such as dyspnea and cough, and may even be life-threatening in severe cases.

[0003] The existing sputum suction device on the market inserts the sputum suction tube into the patient's throat. The air bag on the sputum suction device generates negative pressure to suck the sputum from the patient's throat. However, the traditional air bag has a ventilation process during the working process, which leads to the lack of continuity in the sputum suction process, which not only affects the work efficiency, but also has the risk of sputum reflux. Although the electric sputum suction device can perfectly solve this problem, it has the problems of high cost and inconvenience in carrying compared with the manual sputum suction device. Especially in the absence of power, the manual sputum suction device has become an important first aid tool. Utility Model Content

[0018] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0019] Example

[0020] A handheld sputum suction device described in this embodiment, such as Figures 1 to 4 As shown, it includes a sputum collecting box 9, a fan-shaped mounting frame 1 is fixed to the bottom of the sputum collecting box 9, the mounting frame 1 as a whole forms a fan-shaped structure that is wide at the bottom and narrow at the top, and the top of the mounting frame 1 is in a flat state. An adjustment plate 2 that swings left and right is hinged inside the mounting frame 1, and the adjustment plate 2 is located in the middle of the inner side of the mounting frame 1. The adjustment plate 2 can swing back and forth between the left and right inner side walls of the mounting frame 1 through the hinge; when installing, a hinge block 7 is fixed to the inner top of the mounting frame 1 corresponding to the front and rear sides of the adjustment plate 2, and a hinge hole is opened on the hinge block 7, and hinge columns 6 are fixed to the front and rear sides of the hinge end of the adjustment plate 2, and the hinge columns 6 are independently installed in the hinge hole.

[0021] like Figure 3 and Figure 4 As shown, two airbags 3 distributed on the left and right are arranged in the mounting frame 1, and the airbags 3 are of a foldable fan-shaped structure. The two airbags 3 are respectively located on the left and right sides of the adjustment plate 2, and the two sides of the airbags 3 are respectively connected to the side walls of the adjustment plate 2 and the inner wall of the mounting frame 1. When the adjustment plate 2 is located in the middle of the inner side of the mounting frame 1, the two airbags 3 are in a half-open state, and a hand paddle 5 is fixed to the swing end of the adjustment plate 2. When in use, the adjustment plate 2 can be moved to swing left and right by the hand paddle 5.

[0022] Corresponding to each airbag 3, a first mounting hole and a second mounting hole communicating with each other inside and outside are opened on the mounting frame 1. The first mounting holes are respectively located on the side walls on the left and right sides of the mounting frame 1, corresponding to the two airbags 3 distributed on the left and right; corresponding to the first mounting holes, a first air hole communicating with each other inside and outside is opened on the airbag 3, the airbag 3 on the left is communicated with the first mounting hole on the left through the first air hole, and vice versa, a one-way exhaust valve 4 for discharging the gas in the airbag 3 is installed in the first mounting hole, the one-way exhaust valve 4 is used to discharge the gas in the airbag 3, its air inlet end is communicated with the inside of the airbag 3, and its air outlet end is communicated with the outside of the mounting frame 1, when the airbag 3 is squeezed, the gas inside it is discharged through the one-way exhaust valve 4. The second mounting hole is provided at the top of the mounting frame 1 and communicated with the interior of the sputum collecting box 9. A second air hole communicating with the inside and the outside is provided on the airbag 3 corresponding to the second mounting hole. A one-way air inlet valve 10 is installed in the second mounting hole. The air inlet end of the one-way air inlet valve 10 communicates with the interior of the sputum collecting box 9, and the air outlet end thereof communicates with the interior of the airbag 3. There are two one-way air inlet valves 10, which correspond to two airbags 3 distributed on the left and right and communicate with the two airbags 3 respectively. When the airbag 3 is inflated, the airflow in the sputum collecting box 9 enters the airbag 3 through the one-way air inlet valve 10, so that a negative pressure is formed inside the sputum collecting box 9 to perform sputum suction. A suction nozzle 8 and a sputum collecting bottle 12 which are communicated with the inside are arranged on the side wall of the sputum collecting box 9; a connecting sleeve 11 is fixed on the rear side wall of the sputum collecting box 9, and a through hole which is communicated with the inside and outside is opened on the sputum collecting box 9 corresponding to the connecting sleeve 11, and the bottle mouth of the sputum collecting bottle 12 is connected to the connecting sleeve 11 by a thread; an internal thread which is threadedly matched with the external thread of the bottle mouth of the sputum collecting bottle 12 is opened on the inner side wall of the connecting sleeve 11, so that the sputum collecting bottle 12 and the sputum collecting box 9 can be disassembled, which is convenient for cleaning the sputum collecting bottle 12 or the sputum collecting box 9; the suction nozzle 8 is fixed on the top of the sputum collecting box 9, and a sputum suction hole which is communicated with the inside and outside is opened on the sputum collecting box 9 corresponding to the suction nozzle 8. When in use, the suction nozzle 8 is connected and communicated with the sputum suction tube, and the sputum suction tube enters the patient's throat, and the negative pressure is generated by the airbag 3 to suck the sputum from the patient's throat and enter the sputum collecting bottle 12 along the sputum collecting box 9.

[0023] Specific usage process: the suction nozzle 8 is connected to the sputum suction tube, and the sputum suction tube is inserted into the patient's throat. When in use, the side of the sputum collecting box 9 connected to the sputum collecting bottle 12 faces downward, so that sputum can enter the sputum collecting bottle 12; when in use, the medical staff holds the sputum collecting bottle 12 or the sputum collecting box 9 with one hand, and uses the hand paddle 5 to continuously move the adjustment plate 2 back and forth to swing left and right; the adjustment plate 2 swings to the left, and the air bag 3 on the left is compressed, and the gas inside it is discharged through the one-way exhaust valve 4 on the left. At the same time, the air bag 3 on the right is stretched to the left under the traction of the adjustment plate 2, and negative pressure is generated inside it, and the gas in the sputum collecting box 9 is introduced through the one-way air inlet valve 10 on the right. The air bag 3 on the right side is compressed, and the gas is discharged through the one-way exhaust valve 4 on the right side. At the same time, the air bag 3 on the left side is sucking air, so that the negative pressure in the sputum collecting box 9 continues to be generated, and the sputum suction work is continued, just like the air bags 3 on the left and right sides of the adjusting plate 2 are alternately sucked, so that the negative pressure generated in the sputum collecting box 9 can be continuous, and the sputum can be more effectively sucked out through the sputum suction tube, which effectively improves the work efficiency and avoids the risk of sputum reflux. The structure is simple and the production cost can be reduced to a certain extent.
