20090076443 | DEVICE AND METHOD FOR THE AUTOMATIC INITIATION OF AN INJECTION - A system and method to automatically initiate an injection procedure of a medicament into a patient. In the system, a delivery assembly includes an injector for infusing the medicament into the patient. Further, the system includes a monitor for detecting a parameter characteristic of the procedure, for instance, a pressure indicative of a partial vacuum between the injector and the injection site, a pressure exerted by the patient against the delivery assembly, a conductance, a capacitance, or an optical blood reading. Also, the system includes a timer for determining compliance of the parameter within a predetermined range during a first time interval. In response to the timer, an actuator initiates the injection procedure at the expiration of the first time interval. Further, the actuator may stop the injection procedure if the parameter is outside the predetermined range during a second time interval. | 03-19-2009 |
20090292246 | CASSETTE FOR A HIDDEN INJECTION NEEDLE - A system for injecting a fluid medicament into a patient includes a drive mechanism, and a cassette loaded with a pre-filled hypodermic syringe. When the cassette is loaded, the syringe is held firmly inside and the cassette can be selectively engaged with the drive mechanism. The drive mechanism has two motors. A first motor initially moves the hypodermic syringe from a position inside the cassette where its needle is concealed, to a position where the needle extends from the cassette for insertion into a patient for an injection. With the needle inserted, a second motor pushes the syringe stopper to expel a fluid medicament from the syringe. After an injection, the first motor withdraws the syringe back into concealment inside the cassette, to again firmly hold the syringe on the cassette. The cassette and syringe, in combination, can then be removed from the drive mechanism and discarded. | 11-26-2009 |
20100022955 | SYSTEM AND METHOD FOR AN INJECTION USING A SYRINGE NEEDLE - An auto-injector for injecting a fluid medicament into a patient from a pre-filled syringe requires a disposable cassette that is selectively engageable with the reusable injector. The syringe is latched onto the cassette, and the cassette is then engaged with the injector. Activation of the injector causes a first motor to move the syringe so its needle is extended from a concealed position inside the cassette for injection of the medicament. A second motor on the injector is then activated to expel fluid medicament from the syringe. Then, the first motor is again activated to withdraw the syringe into the cassette for disposal of the cassette/syringe after an injection. | 01-28-2010 |
20100036362 | Injection System with Hidden Needles - An auto-injector confines all functional components inside an enclosed housing, to keep its needle out-of-sight, at all times. Within the housing, a needle holder positions a needle at a location. A drive mechanism then simultaneously engages the needle with a fluid source and accelerates it with a predetermined momentum for insertion into a patient. After fluid delivery, the withdrawn needle is moved to storage within the housing for subsequent disposal. | 02-11-2010 |
20110224616 | AUTOINJECTOR SYSTEM - An autoinjector system for injecting a fluid medicament into a patient includes a re-usable autoinjector, and a disposable cassette loaded with a hypodermic syringe pre-filled with a fluid medicament. The autoinjector includes a first motor for injecting a needle of the hypodermic syringe into the patient and a second motor for expelling the fluid medicament from the syringe. | 09-15-2011 |

20130177455 | System, Method, and Apparatus for Infusing Fluid - A peristaltic pump, and related system method are provided. The peristaltic pump includes a cam shaft, first and second pinch-valve cams, first and second pinch-valve cam followers, a plunger cam, a plunger-cam follower, a tube receiver, and a spring-biased plunger. The first and second pinch-valve cams are coupled to the cam shaft. The first and second pinch-valve cam followers each engage the first and second pinch-valve cams, respectively. The plunger cam is coupled to the cam shaft. The plunger-cam follower engages the plunger cam. The tube receiver is configured to receive a tube. The spring-biased plunger is coupled to the plunger-cam follower such that the expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates pushes the plunger cam follower towards the plunger and thereby disengages the spring-biased plunger from the tube. A spring coupled to the spring-biased plunger biases the spring-biased plunger to apply the crushing force to the tube. | 07-11-2013 |
