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.

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.

A power input end and a power output end are provided. The tool has an interior bore along its entire length. The tool has an exterior surface with a hexagonal cross sectional configuration along its length from the power input end. The tool has a surface with a square cross sectional configuration from the power output end.
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 is structurally 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 liquid-absorbing pad assembly and method of making same are provided wherein such assembly comprises a top layer, a bottom waterproof layer, an absorbent layer between the top and bottom layers, and a multiple-purpose structure disposed between the absorbent layer and the top layer, such structure providing cushioning, means enabling immediate passage therethrough of liquid from the top layer, means substantially preventing reverse wicking of liquid that has passed through the structure, and a suspension which allows air to freely associate with the underside of said top layer for drying purposes.
