    • An apparatus (100) can be connected to an otoscope (500) and used to aspirate the middle ear and to deliver a medicament in the one operation. It can be operated by a single hand, allowing stabilisation of the patient's head during the procedure. The extent of vacuum application and of drug delivery is fully under user control both in terms of volume and duration. Aided by the otoscope (500), and operation of a lever (110) by the second finger extends the lumen (140) which will perforate the tympanic membrane (ear drum). Once the tympanic membrane is punctured, the user will press a vacuum push button (111) which allows fluid to be aspirated from the middle ear through the lumen (140). The extent of vacuum and its duration can be controlled because the clinician can control the movement of the button (111) between the extreme positions. The user will then press a lever (112) to administer a prescribed dose of drug into the middle ear. Again, the extent of medicament flow and its duration can be controlled because the clinician can control the movement of the lever (112) between the extreme positions. The extension mechanism lever (110) is then released.
    • 设备(100)可连接到耳镜(500)并用于吸入中耳并在一次手术中输送药物。 它可以通过单手操作,从而在手术过程中稳定患者的头部。 在体积和持续时间方面,真空应用和药物输送的程度完全由用户控制。 通过耳镜(500)辅助,并且通过第二手指操作杆(110)延伸将使鼓膜(耳鼓)穿孔的内腔(140)。 一旦鼓膜被刺穿,用户将按下真空按钮(111),其允许流体从中耳通过内腔(140)吸出。 可以控制真空度及其持续时间,因为临床医生可以控制按钮(111)在极限位置之间的移动。 然后用户将按压杆(112)将规定剂量的药物施用于中耳。 再次,可以控制药物流动的程度及其持续时间,因为临床医生可以控制杠杆(112)在极限位置之间的移动。 延伸机构杆(110)然后被释放。

    • A rotary device is described for use in a rotary engine, or a compressor, or turbine, the rotary device comprising two rotors disposed adjacent each other and rotatable about substantially parallel axes of rotation. Each of the rotors has protrusions extending therefrom at regular intervals about the circumference of each to define an open portion of a sealable compression chamber between adjacent protrusions. Each protrusion has two side surfaces and a projecting end surface, wherein the meeting point between each side surface and the projecting end surface defines a tip. The two rotors are arranged such that upon contra rotation of the rotors, a protrusion of one of the rotors engages between a pair of protrusions on the other rotor, and the tips of the engaging rotor are in constant sealing contact with the opposing side surfaces of the pair of protrusions for a predetermined period of time. During the predetermined period of time, a sealed chamber is formed and the volume of the chamber is reduced to a predetermined level by the contra rotation.
    • 描述了用于旋转发动机或压缩机或涡轮机中的旋转装置,该旋转装置包括彼此相邻设置并可大致平行的旋转轴线旋转的两个转子。 每个转子具有从其周围以规则的间隔延伸的突起,每个圆周围绕相邻的突起之间限定可密封的压缩室的开口部分。 每个突起具有两个侧表面和一个突出端表面,其中每个侧表面与突出端表面之间的汇合点限定一个尖端。 两个转子被布置成使得当转子反转时,一个转子的突起接合在另一个转子上的一对突起之间,并且接合转子的末端与相对的侧表面保持恒定的密封接触 该一对突起预定的时间段。 在预定时间期间,形成密封室,并且通过反向旋转将室的体积减小到预定水平。
