摘要:
Disclosed is a medical device having an elastic modulus of 100 kPa or more and 2,000 kPa or less, a water content of 10% by mass or less, a tensile elongation of 50% or more and 3,000% or less, and a dynamic contact angle (advancing angle) relative to a borate buffer of 80° or less. The present invention can significantly reduce or avoid a phenomenon of adhesion to a surface when contacted with a surface outside or inside the body, which has hitherto been regarded as a problem in a conventional medical device.

The present invention relates to macroinitiators comprising at least one hydrophobic segments in a molecule, wherein a molecular weight of the hydrophobic segment is 300 to 1800. The present invention further relates to block copolymers, wetting agent and polymeric materials having the block copolymers of the present invention associated with, which is suitable for medical devices, particularly for ophthalmic devices, including contact lenses, ophthalmic lenses, punctal plugs and artificial corneas.
摘要:
A medical device includes a layer made of an acidic polymer and a basic polymer formed on at least a part of a surface of a base material, wherein at least one kind of an acidic polymer and a basic polymer forming the layers made of the acidic polymer and the basic polymer is a multi-component copolymer of three or more components.
摘要:
A medical device includes a layer made of an acidic polymer and a basic polymer formed on at least a part of a surface of a water-containing base material, wherein at least one kind of an acidic polymer and a basic polymer forming the acidic polymer or the basic polymer is a polymer having a hydroxy group.
摘要:
A low water content soft lens for eye is provided, which includes a layer made of an acidic polymer and a basic polymer on at least a part of a surface of a base material containing a polysiloxane compound. Adhesion of the lens to the cornea during wear, which has hitherto been regarded as a problem in a conventional low water content soft lens for eye, can be reduced or avoided when using the low water content soft lens.
摘要:
Provided are a low hydrous soft ophthalmic lens that can remarkably reduce or avoid a phenomenon in which a lens sticks to a cornea when worn and can reduce a decrease in the performance of a coating layer when rubbing the low hydrous soft ophthalmic lens for cleaning and a method for manufacturing the same. The low hydrous soft ophthalmic lens has a layer formed of a hydrophilic polymer on at least part of the surface of a base material containing a polysiloxane compound, and at least part of the inside of the layer is cross-linked.
摘要:
To provide a medical device which is excellent in wettability and lubricity and is also scarcely broken since it is soft, by a medical device in which a layer made of an acidic polymer and a basic polymer is formed on at least a part of a surface of a low water content soft base material, the low water content soft base material containing, as a main component, a copolymer containing a monofunctional monomer component M having one polymerizable functional group and one silicone moiety per molecule.
摘要:
A material for skin is provided including a silicone component-containing polymer obtained by polymerizing a silicone monomer having a carbon-carbon double bond, and a component selected from an antibacterial agent and an alcohol. Provided are a material for skin, which is transparent and has a moderate moisture content, and also has high oxygen permeability, and a method for producing the same.
