Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of oral cavity diagnosis and treatment equipment, belong to oral cavity comfort diagnosis and treatment technical equipment field, specifically one-time laughing gas inhalation anesthesia sedation pipeline, indispensable supporting equipment for laughing gas machine use. BACKGROUND

[0002] The chemical name of laughing gas (N2O) is nitrous oxide, which is a colorless, odorless, slightly sweet inorganic gas. It was first used for surgical operations and oral anesthesia in the mid-19th century and has been used worldwide for nearly 200 years. Laughing gas-oxygen inhalation sedation technology has become a common technique for relieving anxiety in oral diagnosis and treatment in many countries. Its safety and effectiveness have been fully proven, and there are relevant usage specifications.

[0003] During oral diagnosis and treatment, patients inhale a mixture of laughing gas and oxygen at an appropriate concentration, which can produce mild to moderate sedation and some analgesia. The analgesic mechanism of nitrous oxide is to promote the release of endogenous opioid peptides from neurons, activate opioid peptide receptors and descending γ-aminobutyric acid type A (GABAA) receptors, and activate the norepinephrine pathway that regulates the process of pain perception at the spinal cord level. The anti-anxiety mechanism is to directly or indirectly activate GABAA receptors through benzodiazepine binding sites.

[0004] Laughing gas machines are commonly used in clinical practice for inhalation sedation. Laughing gas machines are designed specifically for oral procedures to provide inhalation sedation. Currently, some hospitals use independent delivery systems, while others use pipeline delivery systems. Both independent delivery systems and pipeline delivery systems deliver different proportions of N2O and oxygen to patients through laughing gas inhalation nasal masks.
