摘要:
A non-electric heater apparatus for controllably heating and cooling fluid medicaments flowing from a medicament dispenser through the fluid delivery member of the apparatus by adding a suitable solution or solvent to a chemical component, such as magnesium chloride, or the like, to create an exothermic process that can be used to heat the fluid delivery member and the fluid flowing there through.
摘要:
A method and apparatus for measuring the physical characteristics of livestock animals such as cattle and hogs. The apparatus of the invention includes a plurality of strategically positioned cameras that are used to obtain data concerning volumetric, curvilinear (surface) and linear measurements of livestock animals such as cattle and hogs and the full carcasses thereof. In accordance with the method of the invention, the data is analyzed to provide information that substantially assists the commercial producer of livestock animals in producing a high-quality end-product for the consumer while adding profitability to the enterprise.
摘要:
An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes an elastic distendable membrane, chamber having a fluid outlet. The apparatus also includes a highly novel fluid flow indicator that provides a readily discernible visible indication of fluid flow through the apparatus. Additionally, the apparatus includes a novel adjustable flow rate control means for precisely adjustably controlling the rate of fluid flow from the reservoir of the device.
摘要:
A fluid operated timing device in which the timing interval is determined by the rate at which the fluid flows through a precisely configured rate control frit upon being forced through the frit by an energy source in the form of a compressible elastomeric member.
摘要:
An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes an elastic distendable membrane, chamber having a fluid outlet. Disposed within the fluid chamber is a thin fluid permeable member which precisely controls the rate of fluid flow through the fluid outlet. The apparatus also includes a highly novel fluid flow indicator that provides a readily discernible visible indication of fluid flow through the apparatus. Additionally, the apparatus includes a fill assembly comprising a prefilled vial that can be used to fill the fluid reservoir of the device with a selected medicinal fluid.
摘要:
A compact, patient controlled fluid dispenser for use in controllably dispensing fluid medicament at a selected uniform rate. The device is of an all mechanical construction and is ideally suited for the reliable patient administration of pain killing drugs in the home care environment. To positively regulate the patient administration of the medicament, the intervals at which a selected medicament can be administered, as well as the volume of the dose of the medicament to be administered, is preset by the treating physician and, once set, cannot be altered by the patient. More particularly, the device setting can only be operated by a small physician's key that remains in the possession and control of the treating physician or health care worker.
摘要:
An apparatus for delivering fluids at a precisely controlled rate which comprises a fluid dispensing component having a fluid reservoir for containing the fluids to be delivered and a reservoir fill component which can be removably interconnected with the fluid dispensing component. The dispensing component can be used for the precise infusion of pharmaceutical fluids to an ambulatory patient at controlled rates. The reservoir fill assembly is uniquely designed to accept a vial component of conventional construction which is partially received within a novel adapter subassembly that can readily be removably interconnected with the fluid dispensing component.

摘要:
An apparatus for accurately infusing fluids into a patient at specific rates over an extended period of time. The apparatus is of a low profile, laminate construction having a stored energy source in the form of a distendable membrane, which in cooperation with the base of the apparatus defines one or more fluid reservoirs each having a fluid inlet and a fluid outlet. The apparatus further includes a novel, conformable ullage made of formable materials. The conformable ullage uniquely conforms to the shape of elastomeric membrane as the membrane returns to its less distend configuration and in so doing can move between a central chamber and a toroidal chamber formed in the cover of the apparatus. This arrangement will satisfy even the most stringent medicament delivery tolerance requirements and will elegantly overcome the limitations of materials selection encountered in devices embodying solely rigid ullage construction. Additionally, the infusion cannula of the apparatus is connected to the base in a novel manner which permits expeditious subdermal delivery to the patient via a cannula which extends generally perpendicularly relative to the base.
摘要:
An apparatus for delivering medicaments to a patient which include a fluid dispensing device and a novel cooperating reservoir fill assembly which can be easily and quickly connected to the fluid dispensing device. The fluid dispensing device uniquely includes an elastomeric bladder stored energy type infusion means which can be used for delivering a wide variety of medicaments such as drugs, medicaments, bilogical agents, or other therapeutic agents at a substantially constant rate.
