| 604183000 | Material expelled from reservoir having separate external feed means and discharge outlet | 6 |
| 604185000 | Reservoir squeezed to expel material therefrom | 3 |
| 20100249718 | Self-administration device for liquid medicine - A liquid medicine self-administration device including a flexible reservoir, an operating member, a pushing member to move with respect to the operating member and to induce pressure deformation of the reservoir, and engaging means engages the operating member. With the operating member engaged by the engaging means, the pushing member is relatively moved to the operating member based on restoring force of a spring member to push the reservoir by the pushing member. By disengaging means moving in unison with the pushing member, the engaging means is released from an engaged state with respect to the operating member, when the pushing member has moved to a predetermined location while pushing the reservoir. | 09-30-2010 |
| 20120271242 | ASSEMBLY FOR USE IN A DRUG DELIVERY DEVICE - The present invention relates to an assembly for a drug delivery device comprising a dispensing container and a reservoir container for holding a fluid medicinal product, wherein the dispensing container and the reservoir container are connected to one another and are in fluid communication, and wherein the dispensing container is squeezable for dispensing a dose of the fluid medicinal product from the dispensing container, the dispensing container being refillable with the fluid medicinal product from the reservoir container. | 10-25-2012 |
| 20100137808 | Cartridge For Auto-Injector Apparatus - A cartridge assembly apparatus for an auto-injector includes a flexible container containing a liquid medicant. A needle hub is connected to the flexible container. A needle is attached to the needle hub and extends proximally from the needle hub. A frame is connected to the needle hub and includes a frame proximal end extending proximally beyond a proximal end of the needle. The needle hub and the needle are displaceable relative to the frame in a proximal direction to insert the needle into a patient. | 06-03-2010 |
| 604186000 | Means for metering material flow to or from body | 3 |
| 20130066278 | MODULAR VALVE APPARATUS - Various embodiments are directed to a modular valve apparatus. The modular valve apparatus includes a retaining component having an opening on either end. The modular valve apparatus further includes a cap component having a hole bored through. The cap component may be adapted to be coupled with the retaining component. A generally annular spring component may be disposed within the retaining component and seated on a lower end extending axially toward an upper end of the retaining component. A check ball may be disposed within the retaining component and seated on the spring component. The check ball may be adapted to block the opening bored through the cap component while being held in place by the spring component. | 03-14-2013 |
| 20110245779 | Fluid Valve Systems - An apparatus includes a first valve having an inlet capable of being in fluid communication with a first fluid source and an outlet capable of being in fluid communication with the inlet. The first valve is capable of being in a first mode in which the inlet is in fluid communication with the outlet through a first flow path, and a second mode in which the inlet is in fluid communication with the outlet through a second flow path isolated from the first flow path. | 10-06-2011 |
| 20110178468 | MEDICINAL FLUID INJECTOR WITH BACKFLOW PREVENTION FUNCTION - A medicinal fluid injector having branch lines to inject a ringer solution together with a treatment solution is provided. If the vein of the patient is clogged, the treatment solution is not injected into the patient, but flows back into the ringer solution, which is injected into the patient through a free fall scheme. If the vein is open, the medicinal fluid is excessively injected at a time, causing fatal accident to the patient. To solve this problem, a check valve is installed in an injection tube to prevent the medicinal fluid or the blood from flowing back into the ringer solution even if pressure difference occurs in the medicinal fluid injector. If the medicinal fluid stagnates, an alarm is generated to notify medical staffs of the emergency, so that medicinal fluid injector is safely used. | 07-21-2011 |
