摘要： A system (5, 405) for infusing medication into a subject is provided. The system (5, 405) includes an injection system (50, 450) for controlling fluid flow from a fluid reservoir to a needle. A sensor (20) detects a characteristic indicative of fluid pressure in the needle. The injection system (50, 450) controls the flow of fluid to the needle in response to the characteristic detected by the sensor (20), which continuously detects the characteristic as the needle is inserted into the subject. The system may include a light assembly (100) connected with the injection system. The light assembly (100) may provide a continuously variable signal indicative of the fluid pressure in the needle. The system (5, 405) may further provide a mechanism that provides cues to the operator to insert the needle at a particular rate. The system may further include a conductive element (334) for providing electric nerve stimulation.

摘要： A method and apparatus are provided for locating a target region which is situated in a body of a subject, for example for the delivery of drugs. The system cooperates with a reservoir for receiving an injection fluid, a needle in fluid communication with the reservoir, and a sensor operable to detect a characteristic indicative of the fluid pressure in the needle. A signal generator supplies a success signal to an operator that indicates when the needle is present in the target region. A central controller controls the signal generator in response to signals received from the sensor.

摘要： A medical device for reducing the force necessary to penetrate living being tissue using a variety of reciprocating motion actuators, including piezoelectric, voice coil, solenoids, pneumatics or fluidics. The reciprocating actuator drives a penetrating member, such as a needle, through the tissue at a reduced force while the device detects the passage of the penetrating member through the tissue. Upon passage of the penetrating member through the tissue, electrical power to the reciprocating actuator is automatically terminated. One exemplary method for detecting this passage is via a fluid-containing syringe that is coupled to a channel within the penetrating member. Once the penetrating member tip has passed through the living tissue, the fluid within the syringe no longer experiences any pressure and a plunger within the syringe displaces indicating passage of the penetrating member tip. This motion can provide direct tactile feedback to an operator of the medical device or can automatically open a switch providing electrical power to the medical device. Alternatively, a pressure transducer can also monitor the pressure within the penetrating member channel and automatically activate the switch to cut off the electrical power.

摘要： A device (1) is designed for locating a region which is situated in a body (10). The device has a fluid-filled reservoir (30) which is closed off in a sealed manner by a displaceable plunger (32) and is connected to a hollow puncture needle (20). To measure the pressure prevailing in the fluid, the device has a pressure gauge (40). A signal converter (50) is used to convert a continuous pressure-measurement signal provided by the pressure gauge (40) into a form which is suitable for further processing. A synthesizer (60) is designed to process the converted pressure-measurement signal into a continuous sound signal which is representative of the pressure. If, during a displacement of the puncture needle (20), a needle point (21) reaches the anatomical cavity (15), the result is a readily perceptible change in the sound signal. The device records the pressure-measurement signal over the course of time.
