Description

Technical Field

[0001] The utility model relates to the technical field of dental medical devices, in particular to an air purifier based on the negative pressure system of a dental comprehensive treatment bed. Background Art

[0002] Aerosol is one of the main disease transmission media, and a large amount of aerosol is generated during dental surgery; in order to reduce the spread of aerosol, the prior art adopts the following solutions:

[0003] 1. A saliva suction tube is a suction device directly placed in the patient's oral cavity for sucking out the liquid in the oral cavity, such as saliva, blood, etc.;

[0004] 2. A high-volume evacuator (HVE) for dentistry is a suction device closely attached to the patient's oral cavity. It can capture the aerosol and bacteria not captured by the saliva suction tube;

[0005] 3. Personal protective equipment is used for medical professionals working in high-risk environments. Personal protective equipment can protect professionals from any potential bacteria that may harm them. After the COVID-19 pandemic, the role of personal protective equipment in dental clinics has become more prominent;

[0006] 4. The purpose of an extraoral suction device is to suck out all the aerosol not captured by the saliva ejector or the high-volume evacuator in the patient's oral cavity. It has a flexible robotic arm that allows the doctor to change the angle and position of the device above the patient.

[0007] Although the existing solutions help reduce the spread of aerosol, they all have defects. The saliva suction tube may produce extremely loud noise, and saliva may flow back; the HVE attachment makes the patient feel uncomfortable and is difficult to clean; both of them will block the patient's oral cavity and limit the movement of medical staff. Personal protective equipment such as masks will distort the light, causing eye fatigue for doctors, and may reflect light, causing temporary blindness for doctors. Although the extraoral suction device can help reduce the spread of aerosol, the filtered air will be re-discharged back into the room, disturbing the surrounding air already contaminated by aerosol, causing the aerosol to further spread and rise, and prolonging its sedimentation time.
