Description

Technical Field

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

[0002] The respiratory tract is an important channel for the human body to achieve internal and external gas exchange, and it plays a role in supporting the normal physiological metabolism of the human body. Newborns, the elderly and patients with respiratory tract diseases are prone to difficulty in expectoration. Excessive sputum, pus, etc. can easily block the respiratory tract in severe cases, directly leading to dangerous symptoms of difficulty breathing for patients.

[0003] In clinical procedures, suction is performed by connecting a negative pressure machine to a suction tube. However, the negative pressure machine is difficult to move, and more often a portable suction device is used for suction. For example, a syringe is connected to the suction tube. Due to the characteristics of the syringe itself, after completing a suction operation, if suction is required again, airflow will be pushed into the suction tube. If there is sputum in the suction tube that has not been stored additionally, it will be pushed back into the patient's body. Therefore, a suction device is needed to solve the above problem.

[0011] (III) Beneficial effects

[0012] Compared with the prior art, the utility model provides a sputum suction device, which has the following beneficial effects:

[0013] By pulling the syringe, the air pressure in the suction bottle can be reduced through the suction tube. The reduced air pressure causes the baffle to compress the spring and expose the mounting hole, so that the sputum sucked through the suction tube enters the suction bottle. After completing a suction operation, if suction is needed again, the rubber stopper can be opened. At this time, the air pressure in the suction bottle is balanced through the exhaust hole, and the baffle can be reset by the spring to block the mounting hole. Then the syringe can be pushed to reset, and then the rubber stopper can be plugged for suction. Blocking the mounting hole with the baffle can reduce the possibility of sputum being pushed back into the patient's body. BRIEF DESCRIPTION OF THE DRAWINGS

After completing a suction operation, if suction is needed again, the rubber plug is opened. At this time, the air pressure in the sputum suction bottle is balanced through the exhaust hole, and the baffle is also reset by the spring to block the mounting hole, and then the syringe can be pushed to reset, and then the rubber plug is plugged for suction. Blocking the mounting hole with the baffle can reduce the possibility of sputum being pushed back into the patient's body.

[0022] See also Figure 1-Figure 4 The two sets of mounting components include two sets of mounting plates and two sets of mounting screws. The two sets of mounting plates are fixedly connected to the mounting frame. Two sets of through holes are respectively arranged on the two sets of mounting plates, and two sets of screw holes are arranged on the buckle cover. The two sets of mounting screws slide through the two sets of through holes and are threadedly connected with the two sets of screw holes. The mounting screws are used to facilitate the disassembly and assembly of the mounting frame.

[0023] See also Figure 1-Figure 4 A connecting pipe is provided on the mounting hole, and the inner wall of the sputum suction tube is clamped with the outer wall of the connecting pipe, so that the sputum suction tube can be conveniently disassembled and assembled through the connecting pipe.

[0025] In summary, when the sputum suction device is in use, the syringe is pulled, and the air pressure in the sputum suction bottle can be reduced through the suction tube. The reduced air pressure causes the baffle to compress the spring and expose the mounting hole, so that the sputum sucked through the suction tube enters the sputum suction bottle. After completing a suction operation, if suction is needed again, the rubber stopper is opened. At this time, the air pressure in the sputum suction bottle is balanced through the exhaust hole, and the baffle is reset by the spring to block the mounting hole, and then the syringe can be pushed to reset, and then the rubber stopper is plugged to perform suction.
