20140343490 | LOCKABLE SYRINGE AND METHOD OF ASSEMBLING SAME - A lockable syringe having an actuating mechanism for rapidly and selectively placing a movable thread bearing plunger member and stationary internally threaded cylinder into or out of threaded engagement, particularly for using the syringe to pressurize therapeutic medical balloon catheters, or the like. The mechanism includes a plunger having both a piston at its end to engage a barrel portion of a unitary syringe body, selectively deployable and retractable threaded segment, and an internally threaded cylindrical structure disposed within a unitary syringe body having a barrel. The plunger is engageable with the threaded cylinder by means of a threaded segment, and an operator actuated desmodromic arrangement to controllably reciprocate the threaded segment in a positive manner in order to allow either rapid manual or thread controlled plunger and piston movement within the syringe's barrel for purposes of displacing or pressurizing working fluid contained therein. | 11-20-2014 |
20120067204 | ACTUATING MECHANISM FOR FLUID DISPLACEMENT AND PRESSURIZING DEVICE - A fluid displacement device, particularly for use of the device to pressurize balloon catheters, or the like. The device includes a plunger which is displaceable through a housing, and an actuating mechanism which engages the plunger. The actuating mechanism includes a nut member that is biased into engagement with a threaded portion of the plunger. The device has a press-to-release feature wherein the plunger is instantly releaseable by simply depressing a control surface to overcome a restorative spring force. Subsequently, the plunger can be translated using macro movements (i.e., by pushing or pulling the plunger). | 03-22-2012 |
20110121558 | BONDING SOCKET FOR HIGH PRESSURE MEDICAL HOSE - A socket for receiving a medical hose or tubing. The hose may be, for example, reinforced medical hose. The socket includes an internal conical feature which enters an end of the hose when the hose is inserted in the socket. The conical feature compresses the hose, and places the hose wall under radial compression, which tends to keep the hose retained in the socket, even during a high pressure application. The compression creates a barrier seal between the hose lumen and the conical feature to prevent fluid from contacting the very end of the hose. As such, there is less longitudinal force attempting to push the hose out of the socket. If a reinforced hose is used, the compression places the jacket bond line and each fiber under compression in order to raise resistance to pressurized fluid entry, should the barrier seal be breached. | 05-26-2011 |
20110073497 | CONTACT LENS CASE - An improved contact lens case which includes domes that are provided on hinged members. Preferably, the contact lens case is configured to efficiently utilize space and volume such that no more than 10 cc's of contact lens solution are required to disinfect contact lenses in the case. The hinged members are preferably non-planar which allows the domes to be provided on the hinged members, and allows the use of deep larger diameter, back-to-back cages on the stem, without having to resort to using more than 10 cc's of fluid to immerse contact lenses that are disposed on the domes, between each of the domes and a respective cage. Each of the hinged members has a cylindrically-curved shell form in which the axis of its curve is approximately parallel to the central axis of the central planar stem member. | 03-31-2011 |
20100310429 | METHOD AND DEVICES FOR IMPROVED DISINFECTION PROCESS - A method which enhances a disinfection process by using a catalyst which increases in effective surface area during the process. Also disclosed are contact lens disinfecting systems which are designed to maintain a high concentration of hydrogen peroxide solution for a longer period of time before increasing the overall surface area of catalyst exposed to the hydrogen peroxide solution. The devices utilize pressure from expanding oxygen generated within the system through use of a small catalyst, or through exposure of only a small portion of a large catalyst, to control deployment of the large catalyst for completing disproportionation of the hydrogen peroxide. | 12-09-2010 |

20100233049 | ADDITIVE EFFECT ENHANCED HYDROGEN PEROXIDE DISINFECTION METHOD AND APPARATUS - A method which enhances a disinfection process by obtaining an additive effect from energy and byproducts of the decomposition process. Also disclosed are contact lens disinfecting systems, wherein the systems are configured to create the desirable elevated pressure, oxygen saturation and sustained peroxide concentration conditions within a contact lens holding and reaction chamber, in order to enhance disinfection by additive effect. The systems are configured to provide that an elevated pressure is maintained in the reaction chamber before venting occurs. | 09-16-2010 |
