Estimating the term…
The invention relates to a device (1) for a medical treatment apparatus, the device being configured for measuring a flow of liquids in a lumen (S) inserted in the device, the device having a receptacle (D) and a first ultrasonic transducer (US1), wherein the receptacle (D) of the device (1) has a first guide side (A) and a second guide side (P), so that the lumen(S) has approximately a trapezoidal course when the tube is inserted in the device, wherein the first ultrasonic transducer (US1) is arranged at a first trapezoid corner, and wherein the first ultrasonic transducer (US1) in operation is designed to perform a measurement in or against a direction of flow in the lumen(S). The invention furthermore relates to an ensemble comprising the device and the lumen.
A device for a medical treatment apparatus, the device configured for measuring a flow of liquids in a lumen of a tube when the tube is inserted in the device, the device comprising a first guide side, a second guide side, and a first ultrasonic transducer, wherein a receptacle is defined in the device by the first guide side and the second guide side, wherein the receptacle defines a trapezoidal shape configured to receive the tube therein such that the lumen of the tube has approximately a trapezoidal course when the tube is inserted in the receptacle of the device, wherein the first ultrasonic transducer is arranged within the receptacle and at a first trapezoid corner, and wherein the first ultrasonic transducer in operation is designed to perform a measurement in or against a direction of flow in the lumen.
An ensemble comprising a device for a medical treatment apparatus and a tube, the device configured for measuring a flow of liquids in a lumen of the tube when the tube is inserted in the device, the device comprising a first guide side, a second guide side, and a first ultrasonic transducer, wherein a receptacle is defined in the device in between the first guide side and the second guide side, wherein the receptacle defines a trapezoidal shape configured to receive the tube therein such that the lumen of the tube has approximately a trapezoidal course when the tube is inserted in the receptacle of the device, wherein the first ultrasonic transducer is arranged at a first trapezoid corner of the receptacle, and wherein the first ultrasonic transducer in operation is designed to perform a measurement in or against a direction of flow in the lumen.
