Embodiment 1

[0020] During use, the nasal mask is placed on the patient's nose, one end of the nasal mask is connected to the air supply device, and the other end is connected to the synchronous nitrous oxide oxygen flow adjustment and exhaust negative pressure exhaust system. Turn on the air supply device, the flow of nitrous oxide is controlled by the flowmeter at the intake end (synchronously adjust the flowmeter at the exhaust end to keep the two values ​​the same), then flow through the intake balloon, and then flow into the nasal mask in one direction, and the patient passes through the nasal mask The exhaust gas is discharged after breathing. The exhaust gas flows into the synchronous flow laughing gas negative pressure exhaust system from the nasal mask in one direction. The exhaust gas flows through the exhaust balloon, and the flow is controlled by the flow meter at the exhaust end (with

Abstract

The invention provides a synchronous laughing gas oxygen flow regulation and waste gas negative pressure removal system, and belongs to the field of medical equipment. The system is applied to regulation of flow in the laughing gas calming process of the dental department and removal of laughing gas waste gas in a consulting room. According to the basic principle, by means of synchronous regulation of double airbags and double flowmeters, a patient can obtain the most effective and comfortable gas flow, and meanwhile the laughing gas waste gas is effectively removed. The system comprises a nose mask, balloons (the air inlet balloon and the exhaust balloon), the flowmeters (the air inlet end flowmeter and the exhaust flowmeter), a one-way pipe and a negative pressure interface. Accordingly,the patient can obtain the most efficient and comfortable gas flow, the ideal calming effect is achieved, and meanwhile laughing gas leakage can be reduced and even eliminated, by means of the negative pressure system, the laughing gas waste gas in the dental clinic is safely and effectively removed, and it is guaranteed that the risk that medical staff are exposed in the laughing gas in career is avoided.

Description

technical field [0001] The invention relates to the field of medical equipment. Background technique [0002] Nitrous oxide, also known as "laughing gas", is a colorless, sweet-smelling gas. It is widely used as an inhaled analgesic in dental clinics, N 2 O mixed with oxygen acts as a sedative to reduce patient anxiety. [0003] The sedative effect of nitrous oxide is closely related to the flow rate of the mixed gas (nitrogen-oxygen mixed gas). If the flow rate is too small, the patient will feel oppressed, and the sedative effect will be weakened at the same concentration. When the flow rate is too large, although the sedative effect can be guaranteed, the patient will feel inflated, and the gas is particularly easy to leak, causing laughter pollution in the consulting room. [0004] In the past, the flow adjustment was placed at the intake end, and the flow was adjusted according to the change of the airbag, while the flow adjustment at the exhaust end was ignored. The...
