摘要:
A fluid dispenser for use in controllably dispensing fluid medicaments, such as antibiotics, oncolytics, hormones, steroids, blood clotting agents, analgesics, bio-pharmaceuticals and like medicinal agents from a reservoir that has been filled from pre-filled containers. The fluid dispenser includes a housing to which fill-vials can be connected for filling the dispenser reservoir with the fluid, and a stored energy source provided in the form of a substantially constant-force spring that provides the force necessary to continuously and uniformly expel fluid from the device reservoir. The fluid dispenser also includes a fluid flow control assembly that precisely controls the flow of the medicament solution to the patient.
摘要:
A dispensing device for dispensing medicaments to a patient that is made up of first and second stand-alone, interconnectable assemblies. The first of these assemblies comprises a fluid reservoir assembly that houses a fluid reservoir defining component while the second assembly comprises a fluid delivery and control assembly that includes a novel flow control means that functions to control the flow of medicinal fluid from the fluid reservoir of the first assembly toward the patient via a plurality of fluid flow control passageways. Because the stand-alone fluid delivery and control assembly is initially totally separate from the fluid reservoir assembly of the apparatus, the fluid flow passageways of the fluid delivery and control assembly can be effectively sterilized using conventional gamma ray sterilization techniques without adversely affecting the medicament contained within the fluid reservoir of the apparatus.
摘要:
A method and apparatus for measuring target animals, including livestock animals and full carcasses, and more specifically livestock animals such as cattle and hogs using a single camera system. More particularly, the method of the invention is directed toward obtaining key measurements of the target animal, such as animal weight, animal hip height and animal hip width.
摘要:
An elastomeric bladder stored energy type infusion apparatus that can be filled with a medicinal fluid and, after being filled, can efficiently deliver the medicinal fluid to the patient at a selected, adjustable rate. The apparatus includes a built-in dose dialing mechanism which can be preset by the treating physician or health care worker so that a precise volume of the medicinal fluid can be introduced into the fluid reservoir of the device for delivery to the patient.
摘要:
An elastomeric bladder stored energy type medicament delivery apparatus which can be filled with a medicinal fluid using a closed-end, vial-type fill container and after being filled, can efficiently deliver the medicinal fluid to the patient at a controlled rate. The closed-end, vial-type fill means can be readily connected to and disconnected from the novel fluid delivery component of the apparatus. The fluid delivery device can also be filled by means of a secondary reservoir fill means.
摘要:
An injectable medicament dispenser for use in controllably dispensing fluid medicaments such as insulin, antibiotics, oncolytics and the like from a prefilled container at a uniform rate. The dispenser includes a unique stored energy source in the form of a compressively deformable, polymeric elastomeric member that provides the force necessary to controllably discharge the medicament from the prefilled container which is housed within the body of the device. After having been deformed, the polymeric, elastomeric member will return to its starting configuration in a highly predictable manner.
摘要:
An apparatus for visually indicating fluid flow through a fluid system or apparatus such as a medical infusion device. The apparatus comprises a pair of thin, indicia bearing films disposed in an overlaying relationship. These films are shifted relative to each other by movement of mechanical actuators which are deflected solely by the pressure of the fluid within the fluid conduits of the system of the apparatus. The two films are stacked in closed proximity and are preferably constructed from a substantially transparent flexible material such as mylar. One surface of the inferior film is printed with a plurality of integrated symbols depicting various fluid flow conditions. The superior film functions as a mask over the inferior film and is printed with a pattern of diagonally extending, alternating clear and opaque stripes. The print ratio of the superior film permits viewing at any one time of only one of the symbols printed on the inferior film.
摘要:
A fluid delivery device for infusing medicinal fluids having a self-contained stored energy membrane for expelling fluids at a precisely controlled rate. The device is of a compact, low profile, laminate construction so that it can conveniently be used for the fluids, such as insulin and the like, into an ambulatory patient at controlled rates over extended periods of time. Included within the device are various fluid flow control elements including a unique hydraulic fluid rate control system for ultra low flow delivery. Also included is a highly novel flow indictor for providing a positive indication of fluid flow from the device and for indicating at any given time the amount of fluid remaining in the device.
摘要:
A fluid delivery apparatus which includes a fluid delivery assembly and a unique fill assembly that can be used to controllably fill the fluid reservoir of the fluid delivery assembly in the field. The fill assembly includes a fluid containing vial assembly mounted within a unique adapter assembly which functions to conveniently mate the vial assembly with several different types of fluid delivery assemblies of the character that embody self-contained stored energy means.
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 or layered 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 yieldable materials. The conformable ullage uniquely conforms to the geometry of elastomeric membrane as the membrane returns to its less distended 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 a 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.
