  • Patent number: 9016281
    Abstract: A condom having an indicia disposed on the lower side of the roll when the condom is in the rolled configuration. Preferably, the indicia is a fluorescent marking disposed on the inner side of the condom disposed at a location so that, when the condom is in the rolled configuration, the indicia is visible from the lower side only. More preferably, the indicia is a ring-shaped marking extending about the inner side of the tubular body. In this configuration, a user holding a rolled condom can easily determine which is the upper side of the roll and which is the lower side of the roll. The user may then quickly orient the condom with the lower side facing toward the penis and unroll the condom in the proper direction.

  • Patent number: 5368029
    Abstract: An integral catheter and blood tester includes a needle unit which is receivable within a conventional catheter intravenous tube and housing. The catheter supports a piercing needle and interior chamber. A transparent tester housing is coupled to the needle unit and supports a test strip and test patch which extends into the flash chamber of the catheter needle. A constricting valve surrounds the test strip to maintain closure of the flash chamber. Once the catheter and needle have been inserted into the desired blood vessel, a quantity of blood is introduced into the flash chamber so as to wet the test patch. The test patch may, for example, include conventional litmus material used to test the pH of the test sample. Once the flash process is complete, the needle and tester housing are withdrawn from the catheter to permit conventional intravenous coupling to the catheter. Thereafter, the tester housing is separable from the needle unit to permit discarding of the needle unit.

  • Patent number: 5360018
    Abstract: A viewing device which includes a support; a splash guard with a peripheral wall enclosing an open area to permit visual observation therethrough, with the wall having a surface thereon to receive and support a disposable transparent film positioned across said open area; a post for positioning the splash guard; and a releasable restraint cooperating with the wall surface to releasably secure the transparent film positioned under tension across the open viewing area. There are also adjusting components to permit the splash guard to be positioned in varying angular orientations and at varying heights relative to the support. A variety of restraints are suitable, including resilient bands, toggle straps, flanged caps and compression springs. The device may be used with a variety of transparent films, polyethylene, polypropylene, cellulose acetate, polyester, polyvinylidene chloride and polysulfone.

  • Patent number: 5336192
    Abstract: A self-sealing valve device for an angiographic catheter includes a housing having a first end adapted to form a luer lock connection with the proximal end of the angiographic catheter. A central bore extends between the first end of the housing and an opposing second end, and a deformable elastomeric slit seal is supported across the central bore to selectively seal the proximal end of the catheter. The slit seal is adapted to permit a guidewire to be passed therethrough and advanced into the catheter while sealingly engaging the walls of the guidewire to prevent blood loss through the catheter. The second end of the housing is provided with a female luer lock connection fitting for receiving the conical tip of a syringe, stopcock, or the like, and forming a pressure-tight connection therebetween.

  • Patent number: 5316019
    Abstract: A condom applicator (2) comprising a rolled up condom (4) and a ring member (6) for applying the condom (4) by unrolling it over a penis, the ring member comprising a side wall (8), a flat portion (10), a first lip (12), a second lip (16), and first and second ends (18, 20) which are joined together by a frangible joint (22) which forms the ring member (6) into a complete ring in order to retain the condom (4) in position prior to use of the condom applicator (2) and which breaks during use of the condom applicator (2), and the ring member (6) being constructed to control the tendency of the first and the second ends (18, 20) to twist with respect to each other after the frangible joint (22) has been broken.

  • Patent number: 5316541
    Abstract: An enclosure which can be sterile for performing surgical procedures and a method for its use is disclosed that protects medical personnel from being infected by the patient and the patient from being infected by the surgical environment. The enclosure consists of a tent defining an isolated cavity and having flexible sides at least portions of which are transparent with connected gloves for accessing tools contained within the isolated cavity, an adhesive assembly for securing the enclosure to a patient and a support structure for supporting the tent. The surgeon can operate on a patient by making an incision through the enclosure, the adhesive assembly and the patient's skin. The incision and, consequently, the patient's body fluids, are all contained within the isolated cavity defined by the enclosure. Since the enclosure is collapsible and inexpensive, the entire structure can be disposed of after the surgery. Moreover, the enclosure can be quite small depending on the nature of the procedure.

  • Patent number: 5307794
    Abstract: An apparatus and method for facilitating the transfer of an oscillating ventilator apparatus from one patient to the next, without requiring disinfection of the air pulse generating diaphragm and components, by separating the airway of the patient from the air pulse generating apparatus by a patient isolation apparatus comprising a patient isolation connection unit which mounts a flexible, fluid-impervious diaphragm in sealing relation to the ventilator housing and in adjacent relationship to the outer face of the air pulse generating apparatus, whereby no fluids emanating from the patient can contact said air pulse generating apparatus. The patient isolation apparatus may be disposed of after use with one patient, or may be disinfected and reused.

  • Patent number: 5261421
    Abstract: Antimicrobial gloves such as those made of natural rubber latex may be manufactured by incorporating an antimicrobially effective amount of a non-ionic, sparingly water soluble antimicrobial agent, such as 2,4,4'-tricloro-2'-hydroxyphenyl ether, into the glove material prior to forming the glove. The antimicrobial agent may be present in amounts ranging from 0.1 to 10% by weight of the antimicrobial agent. The wearer contacting surface of the glove may also be dusted with a powder containing an antimicrobial effective amount of an antimicrobial agent such as chlorhexidine digluconate. The powder may comprise a complex of chlorhexidine digluconate and cyclodextrin.

  • Patent number: 5248307
    Abstract: A fluid shield for retarding the spraying and lateral leakage of body fluids from a pressurized anatomical structure includes a transparent flexible shield body terminating in a rim which defines an opening to the interior of the shield body. The rim is adapted to securely engage various body contours surrounding the structure so as to align the opening with the structure. The rim can be secured by adhesives or by manual pressure. The shield body can be penetrable by a surgical instrument for incising the structure, and fluids released from the ruptured structure are captured by the shield body for subsequent disposal. The shield body can be conveniently stored in a compressed stack disposed in a dispensing container. The outer surface of the rim can be textured to pull the next lower fluid shield of the compressed stack partially out of the dispensing container for subsequent removal.

  • Patent number: 5157379
    Abstract: A protective garment, such as a surgeon's glove, is monitored for the occurrence of a breach in that garment. The monitoring is performed using an improved version of the system disclosed in U.S. Pat. Nos. 5,036,309 and 5,109,215. The system is further improved by making the protective garment of one piece with one layer of electrically conductive material and one layer of electrically insulating material, and connecting one of the electrical contacts to the electrically conductive layer. Several forms of the protective garment are disclosed, including a dual layer garment and a triple layer garment. The triple layer garment has two forms, one of which includes an insulating layer sandwiched between two electrically conductive layers, and the other form of which has an electrically conductive layer sandwiched between two insulating layers.
