  • Alert device for intravenous drip
    Patent number: 9662443
    Abstract: An alert device for use with an intravenous drip, comprises two induction ends and a control unit. The control unit comprises a circuit module, an alarm module and a power module. The two induction ends are located on a pipe of the intravenous drip and are contacting with an injection solution inside the pipe. The two induction ends are electrically connected to the control unit by wires. The circuit module detects the induction ends to determine whether the induction ends are in an open-loop status or not. The circuit module connects to the alarm module. The power module supplies power for the control unit. The induction ends uses the injection solution as a conducting means to form an electrically closed loop; when the induction ends do not contact with the injection solution, the induction ends become an open-loop, and thus the alarm module generates alarm signals.

  • Method of reconstituting a substance using an injector device
    Patent number: 9649442
    Abstract: The present invention is directed to an automatic reconstitution drug delivery device. The inventive device effects simple and automatic reconstitution of a dry drug. To effect reconstitution, a user displaces a release button which causes first and second chambers of a drug cartridge to communicate, resulting in automatic mixing of a diluent and dry drug to effect reconstitution of the dry drug. The user then simply sets the dose volume using a dose-setting mechanism, and administers the injection in a manner typical of self-injection drug delivery devices. Whole or partial automatic priming can be also achieved by the device.

  • Plastic stopper
    Patent number: 9642969
    Abstract: A stopper includes a main body portion defining an open rearward end configured to receive the plunger rod, an engagement portion provided along an inner circumference of the main body portion configured to engage at least a top portion of the plunger rod, a closed front end forming a flexible roof, and a first perimetrical skirt extending around an outer circumference of the main body portion toward the closed front end of the main body portion. When fluid pressure is increased inside the syringe barrel during an injection, the flexible roof expands in a radial direction toward an inner wall of the syringe barrel, the first perimetrical skirt is forced against the inner wall of the syringe barrel, and an engagement between the plunger rod and the engagement portion forces the main body portion to expand in the radial direction toward the inner wall of the syringe barrel.

  • Systems and methods for determining location of an access needle in a subject
    Patent number: 9642534
    Abstract: Systems and methods for epicardial electrophysiology and other procedures are provided in which the location of an access needle may be inferred according to the detection of different pressure frequencies in separate organs, or different locations, in the body of a subject. Methods may include inserting a needle including a first sensor into a body of a subject, and receiving pressure frequency information from the first sensor. A second sensor may be used to provide cardiac waveform information of the subject. A current location of the needle may be distinguished from another location based on an algorithm including the pressure frequency information and the cardiac waveform information.

  • System and method for an injection using a syringe needle
    Patent number: 9616173
    Abstract: An auto-injector for injecting a fluid medicament into a patient from a pre-filled syringe requires a disposable cassette that is selectively engageable with the reusable injector. The syringe is latched onto the cassette, and the cassette is then engaged with the injector. Activation of the injector causes a first motor to move the syringe so its needle is extended from a concealed position inside the cassette for injection of the medicament. A second motor on the injector is then activated to expel fluid medicament from the syringe. Then, the first motor is again activated to withdraw the syringe into the cassette for disposal of the cassette/syringe after an injection.

  • Implantable solid-liquid drug delivery apparatus, formulations, and methods of use
    Patent number: 9610398
    Abstract: Embodiments provide apparatus and methods for delivering liquid form medication within the body wherein the medication is stored in solid form and then mixed with a liquid in an apparatus implanted within the body. One embodiment provides an implantable apparatus for in vivo delivery of medication comprising a housing including a reservoir, a store of solid form medication (SSM) and a pump. An SSM element is added to the reservoir along with fluid to form a medication solution comprising at least one drug. The medication solution is then delivered to a delivery site using a pumping means to pump solution from the reservoir through a delivery member such as catheter to a delivery site. Embodiments of the invention are particularly useful for delivering medication to a patient to treat a medical condition over an extended period of time without requiring the patient to take external medication.
