Technical Field

[0001] This utility model relates to the field of sputum suction devices, specifically a sustainable sputum suction device. Background Technology

[0002] In existing technology, for patients with tracheotomy, a cannula needs to be inserted at the incision site. The cannula is designed to open the patient's airway and assist the patient in breathing. When the patient coughs, sputum will be discharged out through the cannula. The cannula is normally in a closed state to prevent outside air from directly entering the patient's body. Therefore, when the patient coughs, the cannula can easily become blocked.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4In this embodiment of the present invention, a sustainable suction device includes a cannula 1 inserted into the trachea through a tracheostomy. A limiting baffle 2 is integrally formed at one end of the cannula 1 outside the trachea. A connecting pipe 3 is threadedly connected to the inner wall of the end of the cannula 1 outside the trachea. A blowout preventer 4 is installed at the output end of the connecting pipe 3. Two anti-backflow valve membranes 12 that can be opened outward are installed inside the limiting baffle 2. An oxygen supply mechanism is installed above the outer periphery of the connecting pipe 3. A sputum suction mechanism is installed on the inner wall of the connecting pipe 3 below the output position of the anti-backflow valve membranes 12.

[0019] In this embodiment: First, the connecting tube 3 is threadedly connected to the sleeve 1. Then, when the patient coughs up phlegm, the phlegm enters the interior of the connecting tube 3 through the sleeve 1. Under the action of the cough airflow, the two anti-backflow valve membranes 12 open, and the phlegm enters the first half of the connecting tube 3 through the anti-backflow valve membranes 12. Meanwhile, oxygen enters the patient's lungs through the oxygen supply mechanism, without affecting the patient's normal breathing. Then, the coughed-up phlegm is collected outward through the phlegm expectoration mechanism. During the patient's coughing process, the anti-spray plate 4 can effectively prevent the phlegm from being sprayed outward directly.

[0020] Please refer to this carefully. Figure 1 and Figure 2 The oxygen supply mechanism includes an oxygen pipe 5 fixedly installed above the outer periphery of the connecting pipe 3. The inner cavity of the oxygen pipe 5 is connected to the inner cavity of the connecting pipe 3. Two one-way inlet valve diaphragms 15 are installed at the output end of the oxygen pipe 5. A second limiting ring 16 protruding inward is integrally formed on the inner wall of the oxygen pipe 5 above the one-way inlet valve diaphragms 15. The farthest ends of the two one-way inlet valve diaphragms 15 are fixedly connected to the inner wall of the oxygen pipe 5. The other positions of the two one-way inlet valve diaphragms 15 are in contact with the inner wall of the oxygen pipe 5 but are not connected.

[0021] In this embodiment: Oxygen enters the connecting tube 3 through the oxygen tube 5, and then enters the patient's body through the sleeve 1. During the patient's cough, the airflow generated by the cough causes the one-way inlet valve diaphragm 15 to close and is blocked by the second limiting ring 16, preventing the one-way inlet valve diaphragm 15 from opening in the reverse direction and preventing sputum from entering the inner wall of the oxygen tube 5.

[0022] Please refer to this carefully. Figure 1 and Figure 2 The sputum clearance mechanism includes a suction tube 6 connected to the lower outer periphery of the connecting tube 3. The input end of the suction tube 6 is located below the output position of the anti-reverse valve diaphragm 12. The output end of the suction tube 6 is inserted into the inner cavity of the collection bottle 7. The bottle mouth of the collection bottle 7 is interference-fitted with a bottle stopper 8. The output end of the suction tube 6 passes through the bottle stopper 8 and enters the inner cavity of the collection bottle 7. The sputum clearance mechanism also includes an inhalation tube 9 that passes through the bottle stopper 8 and enters the inner cavity of the collection bottle 7. The input end of the inhalation tube 9 is connected to an air bag 10, and the output end of the air bag 10 is connected to an exhaust tube 11.

[0023] In this embodiment: by pressing the airbag 10, the air inside the airbag 10 is discharged through the exhaust pipe 11. When the pressure applied to the airbag 10 is removed, the air inside the collection bottle 7 enters the airbag 10, and the air pressure inside the collection bottle 7 decreases. Under negative pressure, the sputum in the connecting tube 3 enters the collection bottle 7 through the suction tube 6. At this time, medical staff can directly see the color of the sputum in the collection bottle 7 without direct contact with the sputum.

[0024] Please refer to the figure carefully. The inner walls of the intake pipe 9 and the exhaust pipe 11 are both connected to outward-opening one-way exhaust valve membranes 13. The inner walls of the intake pipe 9 and the exhaust pipe 11 are integrally formed with a first limiting ring 14 that restricts the one-way exhaust valve membranes 13 from opening inward. The top of the outer periphery of the two one-way exhaust valve membranes 13 are fixedly connected to the inner walls of the intake pipe 9 and the exhaust pipe 11, respectively. The other positions of the two one-way exhaust valve membranes 13 are in contact with the inner walls of the intake pipe 9 and the exhaust pipe 11 but are not connected.

[0025] In this embodiment: when the airbag 10 is pressed, the air inside the airbag 10 is discharged outward through the one-way vent valve membrane 13 in the exhaust pipe 11. When the force applied to the airbag 10 is removed, the external air cannot enter the airbag 10 through the one-way vent valve membrane 13 in the exhaust pipe 11. At this time, the air in the collection bottle 7 enters the airbag 10 through the one-way vent valve membrane 13 in the suction pipe 9. Therefore, the air pressure inside the collection bottle 7 decreases, and the resulting negative pressure can draw the coughed-up sputum into the collection bottle 7.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
