  • Patent number: 6159185
    Abstract: An automatic sampling device is formed of a syringe with a hollow needle, a plug formed of a soft elastic member and slidably engaging the needle to cover at least an opening of the needle, and a guide mechanism situated between the plug and the syringe. The guide mechanism holds the plug to allow the plug to hold the tip of the needle along a center axis of the syringe and to allow the needle to move through the plug from the tip to a root of the needle. When the tip of the needle is located in the plug, the opening of the needle is closed to prevent passage of a fluid therethrough. Thus, a sample gas does not leak through the opening of the needle due to diffusion. Also, since the mechanism for holding the rubber plug provided at the needle tip also acts as the guide for holding the needle tip on the center axis of the syringe, the needle does not generally bend even if a force in an oblique direction is applied to the needle tip.

  • Patent number: 6159188
    Abstract: A process and apparatus (invention) permitting the distribution of micro or submicro liter or gram (exceptionally small) quantities of liquids and powders, (hereafter materials) in patterns and quantities that are especially well-suited for ophthalmologic patient self-application of drugs to his own eye(s) with substantially no overdose. The invention is thus also highly beneficial in those many topical drug applications where overdoses should be avoided. This is particularly applicable for the eye, where overdoses can have many deleterious medical consequences. Use of the invention permits exceptionally small doses of ophthalmologic drugs. Moreover, it also permits the repeatability of the quantity size of the materials chosen for delivery. In the case of drugs, particularly opthomologic drugs, this means that the invention permits the repeated multiple distribution of the same chosen drug/carrier quantity resulting in a uniform repeatable dosage.

  • Patent number: 6156002
    Abstract: A method for measurement of mass and energy transfer parameters (clearance and dialysance) in hemodialysis. A sensor is provided in the dialysate flow path downstream of the dialyzer and means are provided to add concentrate upstream of the dialyzer. A pre-determined amount of a substance whose dialysance is to be measured is added upstream of the dialyzer. The amount of substance not dialyzed in the dialyzer is measured downstream of the dialyzer by said sensor by integrating the concentration over time. Dialysance is calculated from the amount added upstream, the amount measured downstream and the dialysate flow. In case the substance is part of the dialysate the base concentration is subtracted during integration. The addition of the concentrate upstream of the dialyzer can be done manually or, alternatively by the mixing pump of the dialysis machine. Instead of an increase of the concentration with a concentrate dilution with water can be used as well.

  • Patent number: 6156024
    Abstract: An absorbent article, such as a diaper, containing leg cuffs coated with a lotion composition is disclosed. The lotions disclosed in the present invention minimize the abrasion between the cuffs and skin in the area where the cuffs contact the wearer's skin, resulting in less skin irritation. The lotion compositions also reduce the adherence of BM to the skin of the wearer, thereby improving the ease of BM clean up. The lotion composition comprises a plastic or fluid emollient such as mineral oil or petrolatum, an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the emollient on the surface of the diaper leg cuffs, and optionally a hydrophilic surfactant to improve the processability and/or stability of the lotion compositions. Because the emollient is substantially immobilized on the surface of the leg cuff, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.

  • Patent number: 6149638
    Abstract: An absorbent article includes an absorbent pad and an extensible outer cover. The absorbent pad comprises an absorbent core surrounded by a first folded layer and optionally a second folded barrier layer. Folds of the first and second folded layers unfold and thereby open when an extensible bodyside liner and/or outer cover of the absorbent article are extended. The folds, when opened, extend the respective folded layers in a respective cross-direction or longitudinal direction. Extension of the folds of the first and second folded layers prevents tearing of the absorbent pad and damage to, or release of superabsorbent material from the absorbent pad during extension of the absorbent article. The folds can comprise T-folds, C-folds, pleated arrangements, corrugations, or the like.

  • Patent number: 6149633
    Abstract: In a system which utilizes an endoscope and irrigation fluid during surgery within a body orifice, and in which irrigation fluid is withdrawn via a principal path into a suction canister, there is a substantially constant suction and withdrawal rate from the operative site to limit absorption of irrigation fluid within the patient, because a bifurcated flow path that leads to the suction canister not only from the endoscope but also from a drain bag receiving overflow from the body orifice via a tailored drape includes a substantially greater flow impedance in the drain bag path. The common suction line joined to the endoscope line and the drain bag line draws a flow through the endoscope that predominates, to maintain substantially constant withdrawal of irrigation fluid via that path, and substantially eliminates the possibility of loss of suction.
