Background
Local anesthesia, also known as regional anesthesia, refers to the state of being blocked to some extent while the sensory nerve conduction function of a certain part of the body is temporarily blocked and the motor nerve conduction remains intact, by applying local anesthetic to the body part of a patient in a conscious state. This block should be completely reversible without causing any tissue damage. The local anesthesia has the advantages of simplicity, convenience, practicability, safety, patient wakefulness, less complication and small influence on the physiological function of the patient.
When local anesthesia is performed on a patient, the following matters need to be taken into consideration, namely 1, whether the patient has allergy history to local anesthesia is inquired before injection, the dosage is not too large once, and the local anesthesia with the lowest concentration is adopted. 2. Before injection, the injection should be pumped back to avoid entering blood vessel by mistake, and if the local anesthetic enters blood vessel by mistake to cause toxic reaction, the treatment should be carried out in time to avoid respiratory circulation failure. 3. The local anesthesia injection should be accurately positioned, and should be infiltrated layer by layer to the lower layer tissue, and the needle should be slowly inserted to avoid breaking the needle. 4. Local infiltration and anesthesia are not suitable for the infected and cancerous tumor. 5. Avoid the nerve injury caused by puncture. 6. Hematoma is easy to form during local anesthesia puncture, so the bleeding history is inquired before the operation, caution is needed when the operation is carried out near the rich part of the blood vessel, based on the above-mentioned caution, when the medical staff uses the injector to inject the anesthetic into the tissue of the patient, the insertion depth of the needle head and the extruding speed of the injector need to be controlled, and the thumb and the index finger of the medical staff are used in combination with the middle finger during the extrusion or the retraction of the existing injector, so that the operation of the medical staff is troublesome, and the injection of the anesthetic is difficult to control. Therefore, a local anesthesia device for clinical use in anesthesia department is provided.
