Two clamping portions of the hose clamp which can be moved relative to each other can be transferred into a closed relative position in which they pinch off the hose arranged therebetween in such a manner that it is not possible for any medium to flow through the interior of the hose. Moreover, the clamping portions can be moved with respect to each other into an opened relative position in which the hose arranged between the clamping portions is not pinched off, so that the medium is able to flow through the interior of the hose. The pump is distinguished in that a sensor is provided thereon, in particular in the seating for the hose clamp, which sensor detects at least when the hose clamp is received in the seating—whether their clamping portions are in the closed or opened relative position.

    Abstract: A precision syringe pump employing a syringe comprises a motor, a lead screw and a syringe driving head connected to the lead screw. The syringe comprises a cylinder and a plunger. The motor drives the lead screw to rotate clockwise or counterclockwise to drive the syringe driving head and push the plunger to move within the cylinder. The syringe pump further comprises: a magnetoresistive sensor, at least one permanent magnet and an MCU, the at least one permanent magnet being located on the lead screw and rotating therewith; the magnetoresistive sensor can sense the magnetic field generated by the at least one permanent magnet; the input end of the MCU is connected to the magnetoresistive sensor, and the output end of the MCU is connected to the motor; the MCU receives signals from the magnetoresistive sensor and controls, according to the signal feedback, the direction and velocity of the lead screw rotated by the motor.

  • Patent number: 10232109
    Abstract: A mini lead screw pump monitors the rotation of a lead screw by using a magnetoresistive sensor and an MCU, and uses feedback to control the rotation direction and speed of the lead screw through a motor controller so as to control the speed of infusion to a patient. Furthermore, this mini lead screw pump can control the infusion speed of insulin according to the patient's blood sugar concentration monitored by CGM. This mini lead screw pump has several advantages, comprising high sensitivity, high reliability, low power consumption, low cost, and ease of use.

  • Patent number: 10166331
    Abstract: Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device capable of delivering fluid to a user involves identifying a condition of the user that is likely to influence a response to the fluid in the body of the user and classifying the condition as a first type of a plurality of types of conditions. After classifying the condition as the first type, the method continues by adjusting control information for operating the infusion device based on the first type and operating the infusion device to deliver the fluid to the user in accordance with the adjusted control information.

  • Patent number: 10140328
    Abstract: An event notification system has an information system interface that operates to receive critical patient information in messages from dissimilar information systems. The information system interface has functionality that parses information in each message (including the critical information), detects from which information system the message are sent, and operates to detect critical information in each message. Critical information detected in a message received from a core information system is stored and compared to critical information (that should be the same as at least some of the stored critical information) detected in a message received from a non-core information system to determine whether the information is the same.

  • Patent number: 10117673
    Abstract: The present disclosure provides a pressure-depending clutching device for locating and safely positioning a needle in a body cavity. The device is capable of automatically engaging and disengaging the needle from a driving force. The device has a body with an interior space, a pressure-sensing element and a force-receiving element. The pressure-sensing element, the force-receiving element, and the complementary force-sending element form a driving force engaging mechanism for coupling the force-applying structure to the needle during operation. Before the needle reaches the target body cavity, the pressure in the needle causes the clutching device to assume an “engaged” state. When the needle reaches the body cavity, the change in pressure causes the clutching device to assume a “disengaged” state, thereby, automatically positioning the needle in the cavity to avoid overshooting.
