As an important device on the dental treatment chair, the suction device can not only absorb the saliva and water mist in the patient's mouth in time.
Moreover, it can assist the doctor to push the tongue body, and the dental aspirator can prevent the high-speed mobile phone and other instruments from causing damage to the patient's oral mucosa, and provide a clear and dry environment for treatment.
There are two types of suction devices: weak suction and strong suction. The combination of the two can effectively control cross-infection and reduce air pollution in the clinic.
Weak suction: mainly used to absorb water mist, saliva, blood, pus, etc. Strong suction: mainly used to absorb the splashes produced in most treatments.
1. Keep the patient in a comfortable supine position during the treatment process. Avoid touching the head of the suction device to sensitive parts such as the patient's throat. If there is a reaction such as choking or nausea, you should raise your left hand to signal the doctor or nurse to stop the operation.
2. The dental aspirator should be as close to the affected tooth as possible during suction, but its edge should not be close to the tooth. When suction, grasp the placement position and operation essentials to avoid interfering with the doctor's work area. For example, when the maxillary molar area is treated, the suction device should be placed near the maxillary tubercle; when the mandibular molar area is treated, the suction device should be placed near the lingual space of the molar.
3. The action is gentle to avoid the dental aspirator sticking to the mucous membrane and attracting one part for a long time.
Ⅱ. Use and maintenance of dental suction
1. Purpose
(1) In order not to obstruct the surgical field of vision, it is necessary to absorb water mist, powder, and saliva to keep the diagnosis and treatment site clear.
(2) Eliminate the discomfort of water mist, powder and saliva to the patient.
(3) The dental aspirator reduces the damage to the oral soft tissue caused by high-speed handpieces and other instruments, and ensures the operating space in the oral cavity.
(4) Maintain the cleanliness of the clinic and protect the environment.
2. Assembly of the suction head
(1) The suction head of the suction device used in the dental department is slightly different from the suction head used in other medical departments, and the suction tube of the suction device is relatively thin. When installing, the suction head can be directly inserted into the portable dental aspirator, and it is more convenient to replace the suction head.
(2) The suction head of the suction device used in facial and maxillofacial surgery is very small. This is to facilitate the suction head to be inserted into the operation area, and even suction in the extraction socket to make the operation area clear and clear.
3. Suction Procedures
(1) When the surgeon starts the treatment, the assistant should quickly take out the dental aspirator and the three-purpose gun.
(2) Place the suction device and the triple gun near the patient's mouth.
(3) After the operator's high-speed mobile phone and mouth mirror are placed, the suction device or triple-purpose gun should be quickly placed in the area near the treatment site.
4. Aspirator tip part
(1) The position of the dental aspirator during the treatment of the right mandibular molar area: the suction head faces the 9 o'clock direction of the patient's right buccal side, the front end of the suction head extends near the lingual space of the right molar, and the suction tube is in contact with the corner of the mouth.
(2) The position of the suction device during the treatment of the right maxillary molar area: the suction head faces the 9 o'clock direction of the patient's buccal side, the front end of the suction device extends to the maxillary junction of the right molar, and the curved part of the suction nozzle contacts the corner of the mouth.
(3) The position of the suction device during the treatment of the maxillary anterior teeth: the direction of the suction head is the direction of the maxillary 12 o'clock. Cotton rolls can be placed in the vestibular groove to prevent saliva and saliva from flowing out. The tip part is in midline contact with the patient's incisal end and retracts the lip.
(4) The site of the suction device during the treatment of the mandibular anterior teeth: the direction of the suction head is towards the 6 o'clock of the mandible. The part of the dental suction tip is in midline contact with the incisal end of the patient.
(5) The site of the suction device during the treatment of the left maxillary molar area: the suction head faces the 9 o'clock direction of the patient's right buccal side, and the front end of the suction device extends between the buccal side of the left molar and the mucosa and near the maxillary tubercle.
When the curved part of the suction nozzle and the corner of the mouth are in contact with the left mandibular molar, the part of the dental aspirator: the incision of the suction head faces the lower right.
