Description

Technical Field

[0001] The utility model belongs to the technical field of sputum aspirators, and in particular relates to a respiratory tract sputum aspirator. Background Art

[0002] Clinically, many patients cannot cough up sputum on their own, especially newborns and infants, who need artificial assisted suction to keep their respiratory tract open.

[0003] However, the existing sputum suction device is an electric sputum suction device, which is not only expensive, bulky and inconvenient to carry, but also must rely on power to work. When performing rescue work outdoors, it is difficult to find a power source, which makes the electric sputum suction device unusable; at the same time, most of the existing electric sputum suction devices are driven by a motor, which drives the needle core in the syringe to move, thereby generating a certain negative pressure to absorb the sputum. Due to its too fast rotation speed, the pillow core will move too fast, which will cause the sputum to pass over the collection port of the collection bottle, and the sputum will not be able to fall into the collection bottle, and will accumulate in the syringe. When the motor works in reverse, the sputum will remain in the sputum suction tube, resulting in the failure of the sputum suction work, and will also cause secondary harm to the patient.

[0004] Therefore, how to complete the sputum suction work for patients is a problem to be solved at present. Utility Model Content

DETAILED DESCRIPTION

[0026] After the applicant's research and analysis, the reason for this problem (when the motor works in reverse, sputum will remain in the sputum suction tube, which will lead to the failure of the sputum suction work and cause secondary harm to the patient) is that the existing sputum suction device is an electric sputum suction device, which is not only costly, bulky and inconvenient to carry, but also must rely on power to work. When performing rescue work outdoors, it is difficult to find a power source, making the electric sputum suction device unusable; at the same time, most of the existing electric sputum suction devices use a motor to drive the needle core in the syringe to move, which can generate a certain negative pressure to absorb the sputum. Due to its too fast rotation speed, the pillow core will move too fast, which will cause the sputum to pass through the collection port of the collection bottle, and the sputum cannot fall into the collection bottle, and will accumulate in the syringe, and then when the motor is reversed, the sputum will accumulate in the syringe. When the suction tube is working, sputum will remain in the suction tube, which will lead to the failure of the suction work and cause secondary harm to the patient. In order to complete the suction work of the patient, the utility model provides an adjustment component, and then the adjustment knob can be turned to make the syringe generate negative pressure, thereby completing the adsorption of the sputum. In this process, the intensity of the negative pressure depends on the rotation speed of the adjustment knob, which can control the speed of the sputum entering, so that the sputum can fall into the collection bottle. The collection bottle is threadedly connected to the syringe, so that the collection bottle can be disassembled, and the sputum in the collection bottle can be poured out. At the same time, the cooperation of the setting mounting seat and the limit plate and the limit block and the support seat can complete the limiting work of the syringe position, and then the installation and replacement of the syringe can be completed, thereby avoiding cross infection between patients.

In this process, the intensity of the negative pressure depends on the rotation speed of the adjusting knob 21, thereby controlling the speed of sputum entering, thereby enabling the sputum to fall into the collecting bottle 4. The collecting bottle 4 is threadedly connected to the syringe 3, thereby enabling the collecting bottle 4 to be disassembled, thereby enabling the sputum in the collecting bottle 4 to be poured out. At the same time, the setting of the mounting seat 24 and the limiting plate 27 and the limiting block 63 and the supporting seat 62 cooperate to complete the limiting work of the position of the syringe 3, thereby completing the installation and replacement of the syringe 3, thereby avoiding cross infection between patients.

[0032] Description of the working principle: When performing sputum suction, first extend one end of the sputum suction tube 6 into a predetermined position of the human body, and then the medical staff turns the adjusting knob 21, so that the syringe 3 can generate negative pressure, thereby completing the adsorption of the sputum. In this process, the intensity of the negative pressure generated depends on the rotation speed of the adjusting knob 21, so that the speed at which the sputum enters can be controlled, so that the sputum can fall into the collecting bottle 4. The collecting bottle 4 is threadedly connected to the syringe 3, so that the collecting bottle 4 can be disassembled, and the sputum in the collecting bottle 4 can be poured out.
