摘要:
A surgical drive comprises a main panel and a "critical zone" panel secured thereto. A fenestration is formed by cutting through the "critical zone" panel. The main panel is a light weight fabric having a relatively high coefficient of friction. The "critical zone" panel comprises a barrier panel lying against the main panel and an outwardly facing absorbent panel, having an irregular surface. The critical "critical zone" panel is folded to form troughs for capturing liquid incident to a surgical procedure. Corner constructions close the ends of the troughs.

A polyester wrapper fabric having permeability for penetration of steam in sterilization surgical instruments. The fabric is a two by two twill in which the filling yarns are core and affect texturized yarn. A herringbone weave is another embodiment. In other embodiments plain woven portions are combined with the twill and herringbone weaves to minimize ravelling.

摘要:
Reusable, launderable, sterilizable medical barrier fabric or instrument wrap tightly woven from 100% polyester fiber constructed of polyester yarn of from 50 to 150 denier, the sum of the ends and picks of at least 100 per linear inch, is treated with a flame-resistant, water repellent, antimicrobial finish. Medical wraps, garments and like sterilizable articles constructed of this fabric retain their desirable properties after repeated institutional launderings and/or steam sterilizations.

A system for linearizing non-linear transducer output signals includes an analog-to-digital converter having a plurality of digital outputs. A first group of the most significant bits of the analog-to-digital converter digital outputs are coupled to address inputs of a read only memory. The remaining digital outputs of the analog-to-digital converter are coupled to a first group of inputs of a digital multiplying circuit. A first group of data outputs of the read only memory are coupled to a first group of inputs of a summing circuit and represent intersection points of a piece-wise linear approximation to a mathematical curve representing the relationship between unlinearized data produced by the analog-to-digital converter and linearized data produced by the linearizing system. A second group of the read only memory data outputs are coupled to a second group of inputs of the digital multiplying circuit and represent the slopes of straight lines extending from one intersection point toward another. The digital multiplying circuit produces a product word, a predetermined number of bits of which are algebraically summed with the first group of read only memory data outputs. Since the carry bits are connected, the multiplier output is really summed with the entire first group.
摘要:
A medical gown and drape are disclosed in which regions thereof are imprinted with performance enhancing coatings. The gown has regions in the chest and sleeve areas imprinted with a liquid repellent coating to protect the wearer from fluids. The drape preferably has an absorbent or super absorbent coating surrounding a fenestration through which an operation may occur. The drape may also have regions coated with water repellent or friction enhancing materials. The gown further has adhesive closures rather than ties.

An improved surgical gown is provided which has, at its central operative field and the operative zones of the sleeves, a liquid repellent, moisture vapor transmitting material, an inner layer of a breathable material, and an intermediate layer of a liquid proof material interposed therebetween.
摘要:
A liquid impermeable barrier fabric which resists penetration of liquids under finite hydraulic heads and maintains that capable after upwards of 75 institutional washing/sterilization cycles. The barrier fabric istructurally characterized by a silicone membrane attached to a fabric substrate. The substrate is a tightly woven fabric which is constructed of polyester yarns. Attachment of the membrane to the fabric substrate by a bonding mechanism in which the silicone material is in intimate contact with a substantial portion of the looped portions of the yarn, which define the surface of the fabric. This bonding mechanism also includes hydrophilicity of the yarn surfaces with which the silicone is in intimate contact. The fabric is treated with a hydrophilic finish to provide this aspect of the bonding mechanism. This barrier fabric is provided through the use of coating/calendaring apparatus. A film of highly viscous, uncured silicone is formed with a Mooney viscosity of 45 and then pressed between rollers, into a fabric web, to attain the referenced intimate contact. The silicone is then cured.
摘要:
A technique and apparatus for increased sensitivity fluorescence and luminescence emission measurements in which the emission volume is enclosed in a closely fitting cavity having highly reflecting diffuse material inner walls, and with a detector viewing as much of the radiant cavity walls as possible.
摘要:
A pack of laundered, folded and sterilized articles and method of packaging same are provided wherein such articles have at least one band disposed in encircling relation around the pack and holding same in a compact manner wherein the band has overlapping fused end portions and such band is made of a material which does not contaminate the pack.
