[0055] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0056] Reference Figure 1-5 A sputum suction device is shown, comprising:

[0057] Pull-out assembly 100;

[0058] A gas flow regulating device 200 , which is fixed to the gas outlet of the drawer assembly 100 ;

[0059] A negative pressure pipe 300 , which is fixed to the outside of the gas flow regulating device 200 ;

[0060] The air pressure pipe 400 is fixed to the outside of the gas flow regulating device 200;

[0061] A three-way connector 500, the two ends of which are connected to the negative pressure pipe 300 and the air pressure pipe 400 respectively;

[0062] One-way ventilation device 600, which is fixed to the middle of the three-way connector 500;

[0063] A sputum suction tube 700 is fixed to the air inlet of the one-way ventilation device 600 and inserted into the patient's oral cavity;

[0064] The sputum storage component 800 is installed in the middle of the negative pressure pipe 300.

[0065] When the pulling assembly 100 is pulled and a negative pressure is generated by the external drawing of the pulling assembly 100, the gas flow regulating device 200 is driven to block the air pressure pipe 400 and connect it to the negative pressure pipe 300. Since the air pressure pipe 400 is blocked, the negative pressure acts on the one-way ventilation device 600, opening the one-way ventilation device 600, so that the sputum suction tube 700 extracts the sputum in the patient's mouth and transports it to the inside of the negative pressure pipe 300, and then enters the inside of the sputum storage assembly 800 along the negative pressure pipe 300.

[0066] When the pull-out assembly 100 is pushed inward, air pressure is generated in the pull-out assembly 100, and the air flow regulating device 200 is driven to block the negative pressure pipe 300 and connect it to the air pressure pipe 400. The air pressure enters the air pressure pipe 400 and flows, pushing the sputum in the negative pressure pipe 300 to flow, causing the sputum and air to enter the sputum storage tank 810, thereby storing the sputum and discharging the air.

[0067] The gas flow regulating device 200 generates air pressure when the pulling component 100 is pushed and transports it to the inside of the air pressure pipe 400, while blocking the negative pressure pipe 300, so that the air pressure enters the inside of the negative pressure pipe 300 through the air pressure pipe 400, and pushes the sputum into the inside of the sputum storage component 800, so that the pulling component 100 can push the sputum to move while pulling, thereby improving the sputum suction effect of the sputum suction device;

[0068] The negative pressure pipe 300, the air pressure pipe 400 and the one-way ventilation device 600 are connected by the three-way joint 500. When the air pressure pipe 400 delivers air pressure, the one-way ventilation device 600 remains blocked to prevent the air pressure from acting on the interior of the sputum suction tube 700.

[0069] The sputum suction tube 700 is inserted into the oral cavity to extract the sputum in the oral cavity.

[0070] In some embodiments of the present invention, referring to Figure 3 and Figure 4 As shown, the gas flow regulating device 200 includes:

[0071] The outer shell 210 is detachably fixed to the air outlet of the drawer assembly 100;

[0072] The air guide frame 220 is slidably mounted inside the outer shell 210 and slides rightward or leftward under the action of negative pressure or air pressure;

[0073] The spring 230 has two ends connected to the inner end wall of the outer shell 210 and the air guide frame 220 respectively.

[0074] The outer shell 210 guides the sliding of the air guide frame 220, thereby preventing the air guide frame 220 from deviating during sliding and causing gas to enter or leak.

[0075] The spring 230 is arranged to pull the air guide frame 220 to reset when the pressure or negative pressure decreases, and to block the negative pressure pipe 300 and the air pressure pipe 400.

[0076] In some embodiments of the present invention, referring to Figure 3 and Figure 4 As shown, the air guide frame 220 includes:

[0077] The sliding frame 221 is slidably installed inside the outer shell 210 under the action of air pressure;

[0078] An air guide hole 222 is provided on the sliding frame 221;

[0079] The sealing gasket 223 is bonded to the outer surface of the sliding frame 221 and contacts the inner surface of the outer shell 210 .

[0080] When the drawer assembly 100 draws air to generate negative pressure, the sliding frame 221 moves toward the drawer assembly 100 under the action of the negative pressure, stretching the spring 230, causing the spring 230 to store force and driving the air guide hole 222 to adjust its position. When the air guide hole 222 corresponds to the negative pressure pipe 300, the negative pressure will act on the sputum suction tube 700 and the one-way ventilation device 600 through the negative pressure pipe 300 to suction sputum, and the air pressure pipe 400 remains blocked. When the negative pressure decreases, the spring 230 pulls the sliding frame 221 to reset, causing the air guide hole 222 to be offset from the negative pressure pipe 300, thereby blocking the negative pressure pipe 300.

[0081] When the drawer assembly 100 is squeezed to generate pressure, the sliding frame 221 will move away from the drawer assembly 100 under the action of the pressure, and squeeze the spring 230, so that the spring 230 accumulates force and drives the air guide hole 222 to adjust its position. When the air guide hole 222 corresponds to the air pressure pipe 400, the pressure will enter the interior of the negative pressure pipe 300 through the air pressure pipe 400, and the negative pressure pipe 300 is in a state of being blocked by the sliding frame 221, and pushes the sputum inside the negative pressure pipe 300 into the interior of the sputum storage tank 810, and then stores the sputum and discharges the gas. When the pressure decreases, the spring 230 pulls the sliding frame 221 to reset, so that the air pressure pipe 400 is staggered with the air guide hole 222, and the air pressure pipe 400 is blocked.

[0082] Among them, the air pressure pipe 400 and the negative pressure pipe 300 can be blocked by the setting of the sliding frame 221 and the sealing gasket 223, and the air guide hole 222 is driven to correspond to the air pressure pipe 400 or the negative pressure pipe 300 when sliding, so that the air pressure is applied to the air pressure pipe 400 or the negative pressure pipe 300.

[0083] In some embodiments of the present invention, referring to Figure 5 As shown, the one-way ventilation device 600 includes:

[0084] The outer frame 610 is fixed to the middle opening of the three-way connector 500 and is connected to the suction tube 700;

[0085] The sealing ring 620 is fixed inside the outer frame 610 .

[0086] The outer frame 610 ensures the normal installation and use of the sealing ring 620, and a spherical groove is provided in the middle of the sealing ring 620 to allow the gas to pass normally and to seal and block the passage of the gas.

[0087] In some embodiments of the present invention, referring to Figure 5 As shown, the one-way ventilation device 600 further includes:

[0088] A positioning plate 630 , which is detachably fixed to the interior of the outer frame 610 ;

[0089] The blocking ball 640 is slidably mounted inside the outer frame 610 and opens the blocking ring 620 under the action of negative pressure;

[0090] The compression spring 650 has two ends fixedly connected to the blocking ball 640 and the positioning plate 630 respectively.

[0091] When negative pressure is applied to the interior of the outer frame 610, the negative pressure will draw the blocking ball 640 to move, causing the blocking ball 640 to open the blocking ring 620, allowing sputum to pass normally, and squeeze the compression spring 650, causing the compression spring 650 to compress and accumulate force;

[0092] When the negative pressure decreases, the pressure of the compression spring 650 is released, and the blocking ball 640 is pushed into the inside of the blocking ring 620 to block the blocking ring 620;

[0093] The outer frame 610 is blocked by the cooperation of the blocking ball 640 and the blocking ring 620, and the blocking of the outer frame 610 can be further away from the contact, so that sputum can pass normally.

[0094] The positioning plate 630 is provided to ensure the normal installation and fixation of the blocking ball 640 and the compression spring 650 , and the outside of the compression spring 650 can be wrapped with a plastic bag to prevent sputum residue from remaining on the outside of the compression spring 650 .

[0095] In some embodiments of the present invention, referring to Figure 2 As shown, the sputum storage component 800 includes:

[0096] A sputum storage tank 810 is connected to the negative pressure pipe 300;

[0098] One-way valve 830 , the one-way valve 830 is fixed at the top opening of the pressure relief pipe 820 .

[0099] Sputum flows under the action of negative pressure or pressure in the negative pressure pipe 300 and enters the sputum storage tank 810. When sputum flows under the action of pressure, gas also enters the sputum storage tank 810, and the air pressure inside the sputum storage tank 810 increases, opening the one-way valve 830 and allowing the gas to be discharged through the pressure relief pipe 820.

[0100] The sputum storage tank 810 is provided to store the sputum and facilitate centralized processing of the sputum.

[0101] The one-way valve 830 can prevent external gas from entering the sputum storage tank 810 through the pressure relief pipe 820 , and can allow the gas inside the sputum storage tank 810 to be discharged through the pressure relief pipe 820 .

[0102] In some embodiments of the present invention, referring to Figure 3 As shown, the drawer assembly 100 includes:

[0103] The pull-out tube 110 is fixed to the end of the outer shell 210;

[0104] The blocking plate 120 is slidably mounted inside the drawing cylinder 110;

[0105] The pulling rod 130 is fixed on the blocking plate 120 and extends to the outside of the pulling cylinder 110 .

[0106] The pulling rod 130 is pulled, so that the pulling rod 130 drives the blocking plate 120 away from the outer shell 210, so that negative pressure is formed inside the pulling cylinder 110 and acts on the interior of the outer shell 210. The pulling rod 130 is pushed, so that the pulling rod 130 drives the blocking plate 120 close to the outer shell 210, so that pressure is formed inside the pulling cylinder 110 and acts on the interior of the outer shell 210.

[0107] The blocking plate 120 is in sealed contact with the drawing tube 110 , and negative pressure or high pressure is formed under the drive of the drawing rod 130 .
