Abstract

The utility model relates to a high frequency oscillating respirator, which comprises an air current source of high frequency, a connection pipe (7), a low passing pipe (8), a pressure gauge (10), a tachometer (12) and a tracheal cannula (11). The air current source of high frequency comprises an electric motor (3), a fly wheel (2), a connection rod (4) and an air chamber (5) or a linear electric motor (20) or the air chamber (5). Compared with the high-frequency respirator in an acoustic horn type, the high-frequency oscillation respirator adopts the electric motor to replace voice coils and thus a strong flow quantity amplitude is obtained. Compared with the respirator in a piston type, a rubber membrane replaces the piston and thus the noise is reduced. The high frequency oscillating respirator has adjustable air current frequency between 1 to 15Hz and adjustable amplitude between 50 ml to 400 ml with the advantages of large air current amplitude and low noise. The utility model is suitable for the animal experiment and the treatment of the respiratory distress syndrome of the medical clinic.
一种高频振荡呼吸机,它由高频气流源、连接管(7)、低通管(8)、压力计(10)、转速计(12)和气管插管(11)组成。高频气流源由电机(3)、飞轮(2)、连杆(4)和气室(5)组成,或由直线电机(20)和气室(5)组成。这种高频振荡呼吸机与喇叭式高频呼吸机相比,用电机取代了音圈,因而有较大的流量振幅;与活塞式呼吸机相比,用橡皮膜取代了活塞,因而降低了噪声。这种高频振荡呼吸机气流频率在1~15Hz之间可调,振幅在50ml~400ml之间可调,具有气流振幅大、噪声低的优点,适用于医学临床上呼吸窘迫综合症的治疗和动物实验。
