An injection system is described that receives, from one or more sensors, a first group of one or more signals indicating a current volume of injection fluid dispensed from a fluid reservoir at a first time. The injection system determines, based on the first group of one or more signals, that a difference between a dispensed volume limit and the current volume of the injection fluid dispensed from the fluid reservoir at the first time is less than a necessary volume of fluid required to complete both a systolic injection phase and a diastolic injection phase. The injection system further, responsive to determining that the difference is less than the necessary volume of fluid required to complete both the systolic injection phase and the diastolic injection phase, controls the injection system to refrain from performing each of the systolic injection phase and the diastolic injection phase.

A device for performing a tracheotomy on a patient without the assistance of a medical professional. The device may include one or more mechanical arms that cause a blade to create an incision, cause a dilating tool to dilate the incision, and cause a tracheotomy tube to be inserted into the incision. The device may further include a scanner and/or a hollow needle connected to an air pressure sensor that may be used to detect whether the device is aligned with the patient's airway.

A system for infusing medication into a mammalian subject is provided. The system includes an injection system for controlling a flow of fluid from a fluid reservoir to a needle. A sensor is provided that detects a characteristic indicative of the fluid pressure in the needle. The injection system controls the flow of fluid to the needle in response to the characteristic detected by the sensor and the sensor continuously detects the characteristic as the needle is inserted into the subject. The system further includes a conductive element for providing electric nerve stimulation, wherein the system provides electric nerve stimulation in response to the sensor detecting a pressure exceeding an upper limit.

Systems and methods for pumping milk from a breast, wherein the milk is expressed from the breast under suction and milk is expulsed from the pumping mechanism to a collection container under positive pressure. In one approach, the breast pump assembly includes a breast adapter and a receptacle configured to cup the breast adapter, and the breast adapter is removable from the receptacle.

A system includes an endoscope configured for insertion into an internal body cavity and a fluid management system. The fluid management system includes a pump configured to pump fluid through the endoscope into the internal body cavity and a controller configured to determine a pressure within the internal body cavity based upon a current feedback signal received from the pump. A method includes supplying a drive signal to a pump to pump fluid into an internal body cavity, receiving a current feedback signal from the pump, and determining a pressure within the internal body cavity based on the current feedback signal.

The system comprises an intracavity device with an insertable portion having on its outer surface a sensor module which comprises at least a sensor of temperature, humidity or both; a second group of sensors comprising at least a volume sensor, a pressure sensor or both, wherein the fluid flows through the volume and/or pressure sensors; a fluid insufflation module; and a monitoring and control of the homeostasis module connected to the sensor module and to the second group of sensors and which comprises a processing unit.

The method comprises insufflating fluid into the cavity, to maintain a working volume and maintain the homeostasis of the cavity in a continuous manner, in particular the distensibility, temperature and humidity.

Provided are systems and methods for tactile sensing of a target tissue region of a patient in need thereof.

The present invention operates to significantly reduce over or under drainage of cerebrospinal fluid (CSF) from the brain or spinal cord using an extraventricular drain (EVD) in the brain or lumbar drainage device (LDD) and automated intracranial pressure (ICP) monitoring. The present invention attaches the drainage catheter of the EVD to a flow controller or valve which controls the flow of CSF from the drainage catheter and is electronically controlled by a stepper motor communicating with a pressure transducer receiving pressure signals indicating an ICP without the need for constant manual re-leveling.

A system for removing fluid from a urinary tract includes at least one sensor configured to detect signal(s) representative of pulmonary artery pressure and communicate signal(s) representative of the pulmonary artery pressure and a controller. The controller is configured to: receive and process the signal(s) from the at least one sensor to determine if the pulmonary artery pressure is above, below, or at a predetermined value; and provide a control signal, determined at least in part from the pulmonary artery pressure signal(s) received from the at least one sensor, to a negative pressure source to apply negative pressure to a urinary catheter to remove fluid from a urinary tract when the pulmonary artery pressure is above the predetermined value and to cease applying negative pressure when the pulmonary artery pressure is at or below the predetermined value.

A system for removing fluid from a urinary tract includes: at least one sensor configured to detect signal(s) representative of bioelectrical impedance and communicate signal(s) representative of the impedance; and a controller. The controller is configured to: receive and process the signal(s) from the at least one sensor to determine if the impedance is above, below, or at a predetermined value; and provide a control signal, determined at least in part from the signal(s) representative of the impedance received from the at least one sensor, to a negative pressure source to apply negative pressure to a urinary catheter when the impedance is below the predetermined value and to cease applying negative pressure when the impedance is at or above the predetermined value.
