摘要:
An antithrombogenic material having its surface modified by ion implantation is disclosed. This antithrombogenic material may, for example, be a silicone material which has its surface modified by introducing functional groups on its surface by ion implantation. The material exhibits improved compatibility to blood due to introduction of the functional groups by ion implantation and the doping effect of the implanted elements.

Provided are a temperature measuring probe separable from a main body which includes a signal processor, and an electronic clinical thermometer equipped with this probe. The temperature measuring probe includes a temperature measuring circuit supported by a flat, flexible, strip-shaped base member, in which the temperature measuring circuit is sealed by a coating member, such as a film, and/or a filler, one end thereof being treated to form a connector. This structure allows the overall probe to be formed into a film-, sheet- or plate-like configuration. Preferably, a core member is provided between the base member and coating member, with the flexibility and rigidity of the overall probe being decided by selecting the thickness, material and cross-sectional configuration of the core. The temperature measuring circuit preferably is composed of the minimum number of required circuit elements, and individual probes are provided with interchangeability by trimming, selection of characteristics or other treatment.

A cell adhesive material with excellent cell adhesion and cell proliferating property and a method for producing the same are provided. The adhesion and proliferation of cells can be improved remarkably by the surface modification of a cell adhesive material comprising a polymer material containing carbon as a constituting element, such as polystyrene or segmented polyurethane, wherein at least a part of the surface is modified by ion bombardment through ion implantation. The method for producing such cell adhesive material comprises implanting ions into at least a part of the surface of the polymer material. The cell adhesive material and the method for producing the same are promising for application to cell culture petri dishes and hybrid-type medicinal materials.

A temperature measuring probe includes a temperature measuring circuit having a temperature sensing body supported by a flat, flexible strip-shaped base member, in which the temperature measuring circuit is sealed by a coating member, such as a film, and/or a filler, one end thereof being treated to form a connector. This structure allows the overall probe to be formed into a film-, sheet-, or plate-like configuration. Preferably, a core member is provided to the base member and coating member, with the flexibility and rigidity of the overall probe being decided by selecting the thickness, material and cross-sectional configuration of the core. The core includes at least one cavity. The thickness of the core member at a portion of the at least one cavity being approximately the same as that of the temperature sensing body. The core member has a smoothly diminishing thickness from the at least one cavity toward the rearward end of the probe.

There is provided herein a curable silicone elastomer composition comprising the following components: (A) 100 parts by weight of a polyorganosiloxane having at least two silicon-bonded vinyl groups per molecule, (B) 1 to 300 parts by weight of fine powders of tungsten carbide and (C) a component for crosslinking of said component (A) selected from the group consisting of (1) a combination of (a) 0.1 to 10 parts by weight of a polyorganohydrogensiloxane having an average of at least two silicon-bonded hydrogen atoms per molecule and (b) 0.000001 to 0.1 part by weight of a platinum catalyst; (2) a combination of said (a), (b) and (c) 0.00001 part to less than 0.1 part by weight of an organic peroxide except from organohydroperoxide; (3) a combination of said (a) and (d) 0.00001 part to less than 0.2 part by weight of the reaction product between said (b) and (c); and (4) 0.1 to 3.0 parts by weight of an organic peroxide except from organohydroperoxide. The composition according to the present invention shows excellent X-xay shielding effect as well as excellent anticoagulative effect, and can give an elastomer of high quality by curing with a broad scope of catalyst systems.
摘要:
An antithrombogenic material whose stickiness to cells is maintained but whose stickiness to blood platelet is inhibited, is disclosed, which comprises a substrate and a biopolymer material coated on said substrate, the antithrombogenic material being obtained by irradiating the biopolymer material with ion beam to maintain its stickiness to a cell but reduce its stickiness to a blood platelet. In accordance with the present invention, there is also provided a method for producing the antithrombogenic material.
摘要:
A rotational drive sensor 31 which allows a radiation source 10 and a twomensional sensor 20 which are caused to be in one body to turn round a subject 50. An X-ray vessel 13 irradiates X-rays to the subject 50 in a pulsated manner. An X-ray/light conversion element 21 converts an X-ray transmitted image to an optical image. A CCD camera 23 picks up this optical image. An information processing unit 40 reconstructs a three-dimensional pictorial image on the basis of two dimensional pictorial images in plural directions obtained, and a display monitor 46 displays this three-dimensional pictorial image. A controller 39 controls the distance between the X-ray vessel 13 and the X-ray/light conversion element 21 and the focal size of the X-ray vessel 13 on the basis of the size of the subject 50. As a result, it is possible to obtain, in a short time, a three-dimensional pictorial image having less distortion and high resolution in a broad region, and to reduce X-ray exposure quantity to much more degree as compared to the conventional system.
