DETAILED DESCRIPTION

[0019] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1 and Figure 2The utility model provides a sputum suction tube for newborns, including a medical negative pressure device, a negative pressure connecting tube 3 is fixedly installed at the air suction end of the medical negative pressure device, the other end of the negative pressure connecting tube 3 is connected to a transfer cylinder assembly 1, the other end of the transfer cylinder assembly 1 is connected to a sputum suction tube main part 2, the transfer cylinder assembly 1 includes a sputum storage cylinder 11, a valve type piston 13 is slidably sleeved inside the sputum storage cylinder 11, a suction pipe head 12 connected to the inside of the sputum storage cylinder 11 is arranged on one side of the sputum storage cylinder 11, a push-pull pipe 14 is connected to the side wall of the valve type piston 13 away from the suction pipe head 12, the negative pressure connecting tube 3 is fixedly sleeved on the side wall of the push-pull pipe 14, and the sputum suction tube main part 2 is fixedly sleeved on the side wall of the suction pipe head 12.

[0021] Reference Figure 2 A handle 15 is fixedly connected to the side wall of the push-pull tube 14 , and the handle 15 can be provided to facilitate pushing and pulling the push-pull tube 14 .

[0022] Reference Figure 3 The air valve piston 13 includes a fixed block 133, one side of the fixed block 133 is fixedly connected to a valve housing 131, the valve housing 131 and the fixed block 133 are both slidably sleeved inside the sputum storage tube 11, one side of the valve housing 131 is provided with a through hole that penetrates to the inside, an inner valve body 132 is arranged inside the valve housing 131, a plurality of air holes that penetrate to the inside are provided on the side wall of the inner valve body 132, a threaded hole that penetrates to the other side is provided on one side of the fixed block 133, a push-pull tube 14 is threadedly sleeved in the threaded hole, one end of the push-pull tube 14 is fixedly connected to the inner valve body 132, and the push-pull tube 14 is communicated with the inside of the inner valve body 132, a gap is formed between the side wall of the inner valve body 132 and the inner wall of the valve housing 131, and the width of the inner valve body 132 is lower than the inner width of the valve housing 131. When the inner valve body 13 When the side away from the push-pull tube 14 does not contact the inner wall of the valve housing 131, the air valve piston 13 is in the valve open state. When the medical negative pressure device is in operation, the air flow can enter the valve housing 131 through the through hole of the valve housing 131, and the gas enters the gap between the valve housing 131 and the inner valve body 132 through the air hole of the inner valve body 132 and enters the inner valve body 132, and then flows into the push-pull tube 14, thereby making the transfer cylinder assembly 1 in the suction state. By rotating the push-pull tube 14, the push-pull tube 14 can drive the inner valve body 132 to move under the influence of the thread structure, so that it is close to the inner wall of the valve housing 131 and the through hole of the valve housing 131 is blocked. At this time, the air valve piston 13 is in the valve closed state. When the air valve piston 13 moves, the pressure inside the sputum storage tube 11 can be increased.

[0023] Reference Figure 3 A rubber sealing ring is provided on the side wall of the valve housing 131. By providing the rubber sealing ring, the sealing performance of the gap between the side wall of the valve housing 131 and the inner wall of the sputum storage tube 11 can be improved, thereby preventing sputum inside the sputum storage tube 11 from penetrating into the gap between the side wall of the valve housing 131 and the inner wall of the sputum storage tube 11.

[0024] Reference Figure 3A sealing gasket 134 is fixedly connected to the side of the inner valve body 132 away from the push-pull tube 14. The sealing gasket 134 can improve the sealing effect when the inner valve body 132 blocks the through hole of the valve housing 131.

[0025] Reference Figure 3 The fixing block 133 is fitted in the clearance inside the sputum storage tube 11 to avoid excessive resistance when the air valve piston 13 moves.

[0026] Reference Figure 4 Two positioning blocks 16 are fixedly connected to the inner wall of the sputum storage tube 11, and two embedding grooves are provided at one end of the side wall of the fixed block 133. The two positioning blocks 16 are respectively adapted to the two embedding grooves of the side wall of the fixed block 133. When the air valve piston 13 moves to make the positioning block 16 fit into the embedding groove of the side wall of the valve housing 131, the fixed block 133 can be positioned to prevent the fixed block 133 from rotating when the push-pull tube 14 is rotated.

[0027] The working principle of the utility model is as follows: when in use, the suction tube main part 2 is inserted into the nasal cavity, and the transfer tube assembly 1 can be pumped to negative pressure to generate suction through the medical negative pressure equipment under the connection of the negative pressure connecting tube 3, so that the suction tube main part 2 can absorb sputum in the nasal cavity under the action of the transfer tube assembly 1, and the sputum enters the interior of the transfer tube assembly 1 through the suction tube main part 2, that is, enters the interior of the sputum storage tube 11 through the suction tube head 12 for storage. When sampling the sputum of the newborn, the suction tube main part 2 is first unplugged, and then the valve of the air valve piston 13 is closed, and then the air valve piston 13 is driven to shift to the interior of the sputum storage tube 11 by pushing the push-pull tube 14, and the interior of the sputum storage tube 11 is pressurized so that the sputum in the sputum storage tube 11 is discharged through the suction tube head 12, thereby making the sampling process more convenient and quick.
