Some embodiments disclosed herein related to a device for transferring precise amounts of fluid from at least one source container to a at least one target container. In some embodiments, the fluid is first transferred from the source container (e.g., a vial) through a connector to an intermediate measuring container (e.g., a syringe). In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial. An air check valve or a bag or a filter can prevent the fluid from escaping through the air inlet. The precisely measured amount of fluid can then be transferred from the intermediate measuring container to the target container (e.g., an IV bag). In some embodiments the connector can include a source check valve and a target check valve to direct fluid first from the source container to the intermediate measuring container and then from the intermediate measuring container to the target container. Some embodiments of the device can include a motor and a controller for automatically actuating a plunger of the syringe to transfer the desired amount of fluid.

A controller for closed loop control of infusion devices is described. A variety of infusion systems are described that use the closed loop control architecture. In some embodiments the closed loop control may be adapted to current commonly used infusion means such as a gravity feed intravenous system. Other embodiments describe infusion pump system that use biasing or drive mechanisms of springs, elastomers, rotary and linear motors.

A method and apparatus for pressure infusion and temperature control of infused liquids includes a receptacle for receiving a liquid-filled bag containing intravenous solution or other liquid and an inflatable pressure device. The inflatable pressure device is disposed within a pressure device bag and is positioned proximate the liquid-filled bag in the receptacle. The inflatable pressure device expands within the pressure device bag upon inflation and exerts pressure on the liquid-filled bag. A heating element may be disposed on the inflatable pressure device bag to heat the liquid-filled bag to a desired temperature. The liquid may alternatively be maintained at a desired temperature, while flowing to a patient via a heating assembly disposed along a tube. The heating assembly includes a sleeve having a slot for receiving the tube and a plurality of individually controlled heaters. An infrared sensing device is mounted proximate a drip chamber to ascertain a drip count, while a temperature sensor is disposed within a holder that is positioned toward the entry site on a patient. A heat controller controls the heaters based on a drip count, while a safety controller disables heater operation in response to liquid temperature exceeding the desired temperature. Thus, the safety controller and heat controller, in combination, control the heating assembly heaters based on liquid temperature and flow rate, respectively. Alternatively, the liquid-filled bag may be heated to a desired temperature whereby the heating assembly includes a single heater controlled by a controller to maintain the liquid at the desired temperature during infusion of the liquid into a patient.

An intravenous drug access system. In one embodiment of the invention, the drug access system includes an IV bag having an inlet port and outlet port, whereby the inlet port is a female luer integral therewith. The integral female luer fitting may be fitted with a sealed end cap comprising a male luer insert with a closed end. An alternative embodiment of the present invention comprises a discrete pre-molded connector made with one spike at one end and a female luer fitting at the opposing end. The spike is used to penetrate a standard IV bag through a conventional inlet port.

An injection port for an intravenous bag including a generally hollow tube that is mountable to the intravenous bag. The hollow tube has a first end. A polymeric plug is mounted in the first end. The polymeric plug is integrally molded into the tube proximate the first end. A method for constructing the injection port including injecting a first molding material into a mold cavity, allowing the first molding material to at least partially cure and harden, moving a movable mold part to expose a first cavity defined by inner surfaces of the at least partially cured and hardened molding material, injecting a second mold material into the first cavity, allowing the second molding material to at least partially cure and harden such that the second molding material bonds with the inner surfaces and removing the injection port from the mold.

A multiport infusion device used as an intravenous administrator of prescribed fluid is provided. The device includes a band adapted to be secured to a user's body part near an intravenous therapy location. A multiport body is secured to the band and includes a multiport fluid exchange route fluidly communicating between a first port and at least a second port of the body's ports.

The present invention provides a pharmaceutical composition for treating patients with HIV infection. The pharmaceutical composition is in the form of an intravenous injection solution and optionally capsules. The pharmaceutical composition contains fourteen (14) ingredients, i.e., diffuse hedyotis, bistort rhizome, giant knotweed rhizome, Asiatic moonseed rhizome, baical skullcap root, bovine biliary powder, milkvetch root, barbary wolfberry fruit, sanqi, figwort root, Chinese magnoliavine fruit, turmeric root-tuber, hawthorn fruit, and Chinese angelica.

Disclosed is a method for lowering elevated uric acid levels in a patient having a plasma level of uric acid (pUAc) of more than about 6 mg / dL, the method consisting of administering to said patient an intravenous injections every 2 to 4 weeks of about 8 mg PEG-uricase.

A mixture for intravenous injection to treat damaged vascular structures contains a mixture of carbamide peroxide and a sclerosing agent. The injected mixture expresses blood from the affected vascular structure by formation of bubbles, in situ. The bubbles carry the sclerosing agent into contact with the lining of the vascular structure resulting in destruction. The size of the bubbles may be varied by adding hydrogen peroxide and varying the proportions of carbamide peroxide and hydrogen peroxide in the mixture.

An infusion and blood collection device allows clean blood collections into a collection tube via a previously installed angiocatheter without interrupting the administration of intravenous therapies after initial installation. The device optionally includes passive control of the blood collection flow rate to prevent contamination of the collected blood draw with the IV therapy fluid being simultaneously infused through the angiocatheter. A blood collection method uses an infusion and blood collection device to draw a clean blood sample from a patient and into a collection tube via a previously installed angiocatheter without interrupting the administration of intravenous therapies.

A vascular access device having a fluid chamber in which UV-C radiation is emitted to irradiate pathogens contained in an infusate flowing though the fluid chamber.

The invention discloses a superficial blood vessel display method, which comprises the following steps that: an LED (light-emitting diode) light source respectively emits near infrared light with two wavelengths; the near infrared light is polarized to obtain linearly polarized light which irradiates human body skin surface; blood vessels of human body subcutaneous tissues carry out multi-scattering on the linearly polarized light to obtain depolarized near infrared light; the depolarized near infrared light is polarized again to obtain polarized depolarized near infrared light; a camera respectively shoots the polarized depolarized near infrared light with two wavelengths to generate two blood vessel images; the camera performs signal processing and electronic processing on the two blood vessel images and sends the processed images to a projector; and the projector shows the blood vessel images and projects to the skin of a patient. The display method and instrument disclosed by the invention have the following beneficial effects: the blood vessel image of the patient are precisely projected to the skin of the patient without distortion, and vein, artery and skin tissues are marked with different colors, thereby guiding doctors and nurses to carry out intravenous injection and surgical operation.
