A throttling component and a conditioning and flowrate measurement device including a throttling component. The throttling component comprises a central throttling element and multiple peripheral throttling elements. The multiple peripheral throttling elements are sequentially sleeved on the exterior of the central throttling element, and are coaxial to the central throttling element; annular fluid channels are respectively formed between the central throttling element and its adjacent peripheral throttling element, and between adjacent peripheral throttling elements. A sensitive and clear differential pressure signal is generated while the throttling component stabilizes the flow, so that the accuracy and reliability of flowrate measurement can be improved.

A venturi flowmeter includes a ring of which the inside is hollow and which prevents inner wall abrasion or fatigue load accumulation at a main orifice and thus can reduce maintenance costs. The venturi flowmeter includes a main orifice of which the inside is hollow and an element of which one side has a hollow inside having the same diameter as that of a through-hole of the main orifice, and which has a tapered shape toward the other side thereof. A diffuser has one side having a hollow inside of the same diameter as that of the through-hole of the main orifice, and which has a tapered shape toward the other side thereof. A ring is connected between the main orifice and one side of the element. The ring includes a stopper formed along an inner wall and having a hollow central portion.

A sensing arrangement for a medical device includes a housing having a rigid portion and a flexible portion, a collar of the flexible portion attached to an exterior of the rigid portion such that a stem of the rigid portion extends into an interior of the flexible portion. A sensing element is positioned at least partially within a passageway of the rigid portion, with at least one wire extending from the sensing element through the passageway and into the interior of the flexible portion. Front and rear flanges protrude from the flexible portion and are adapted to allow the sensing arrangement to be attached into an aperture in a wall of the medical device. The stem of the rigid portion may be positioned between the collar and front flanges of the flexible portion, such that the stem does not extend through the aperture of the wall of the medical device. There are also provided a seal, a removable component, a medical device and a system.
