摘要:
An ophthalmic lens suited for extended-wear periods of at least one day on the eye without a clinically significant amount of corneal swelling and without substantial wearer discomfort. The lens has a balance of oxygen permeability and ion or water permeability, with the ion or water permeability being sufficient to provide good on-eye movement, such that a good tear exchange occurs between the lens and the eye. A preferred lens is a copolymerization product of a oxyperm macromer and an ionoperm monomer. The invention encompasses extended wear contact lenses, which include a core having oxygen transmission and ion transmission pathways extending from the inner surface to the outer surface.

摘要:
The invention relates to a process for coating a material surface, comprising the steps of: (a) applying to the material surface a tie layer comprising a polyionic material; (b) covalently binding a bifunctional compound comprising an ethylenically unsaturated double b3nd to the tie layer; and (c) graft polymerizing a hydrophilic monomer onto the compound comprising the ethylenically unsaturated double bond. The coated articles that are obtainable by the process of the invention have desirable characteristics regarding adherences to the substrate, durability, hydrophilicity, wettability, biocompatibility and permeability and are thus useful for the manufacture of biomedical articles such as ophthalmic devices.
摘要:
A defibrillator and method for delivering defibrillation energy to a patient are described. A patient ECG is analyzed and defibrillation energy is delivered to the patient in response to receiving manual input. The patient ECG is further analyzed while waiting for the manual input and the defibrillation energy is delivered to the patient after a time delay if the manual input is not received.
摘要:
A method and article for packaging an automatic external defibrillator for use without a prescription are described. The OTC AED is encased in a rigid polymeric disclosure which is a distinctive color or set of colors to enable the OTC AED to be readily distinguished in the home environment. The defibrillator is packaged in a box with multicolored depictions of the defibrillator on multiple sides of the box, which enable the distinctive coloring of the defibrillator to be readily identified by the exterior of the packaging.
摘要:
A CPR guidance device for placement and use on the chest of an adult patient. The device guides a rescuer in the application of an adult CPR protocol. The device also senses patient characteristics indicative of an infant patient. If the device senses that the patient in an infant, it appropriately warns the rescuer that the device is for adult patient use only.
摘要:
An automatic external defibrillator is shipped from the manufacturer with the battery installed in the battery compartment of the AED. During shipment a removable tab is located between a battery terminal and an electrical contact inside the battery compartment. Upon receipt of the AED the user pulls the tab to remove it from the battery compartment. This completes the circuit between the AED and its battery and the AED begins a self-test. A packaging panel covers the controls of the AED to prevent actuation of controls during the self-test. The packaging panel includes instructions for setup of the AED including indication of a control to actuate during or at the conclusion of the self-test.
