A medicine temperature control device which is attachable to or detachable from a medicine pressure injection system and a driving method thereof are provided. A medicine temperature control device which is attachable to or detachable from a medicine pressure injection system includes a pressurization module which includes an expansion unit which expands to pressurize a container containing a medicine, a controller which supplies and pressurizes a fluid to the expansion unit and controls a temperature of the medicine, and a power source which supplies a power to drive the controller; and a temperature control module which includes a temperature control chamber to control a temperature of the medicine.

The present disclosure relates to a medicament delivery device. The medicament delivery device comprises a housing, a needle and a reservoir. The needle is configured to project from a distal end of the housing. The reservoir is disposed in the housing and has a flexible wall. The medicament delivery device further comprises a dispensing member and a biasing member. The dispensing member is disposed in the housing and the biasing member is configured to bias the dispensing member to move in an arcuate path relative to the housing such that the dispensing member moves across the flexible wall of the reservoir to dispense medicament from the reservoir when the reservoir contains medicament.

Provided is a medicine injection device capable of injecting a liquid medicine into a human body by using a medicine container configured to discharge the medicine contained therein along a designated path when a pressure is applied from outside, the medicine injection device including one or more medicine pressing units including one or more inflatable parts capable of being inflated by air to apply a pressure to the medicine container, and a first pumping unit capable of inflating one of the inflatable parts by including a first pump capable of generating air of a preset pressure, and a first pipe connectable to the one of the inflatable parts. According to the present invention, a risk of breakdown and a total manufacturing cost may be reduced due to a simple structure of the medicine injection device.

A drug delivery device includes a drug product container, a pressurized vessel, and an urging member. The drug product container can have at least one flexible wall and defining a cavity configured to contain a drug product. The pressurized vessel can contain a gas under pressure. And the urging member is in working connection with the pressurized vessel such that, upon at least partial release of the gas under pressure, the urging member moves from a first portion of the drug product container to a second portion, thereby ejecting at least a portion of the drug product from the drug product container.

A portable system and method for infusing fluid medicaments to a patient through an elastomeric fluid channel includes an airtight pressure shell for holding a collapsible bag of the fluid medicament to be infused. A pressure sensor connected to the pressure shell monitors decreases below ambient pressure inside the shell to determine when the ambient pressure becomes insufficient to continue assisting the withdrawal of fluid from the collapsible bag, to an external pinch/squeeze unit. At this point, an equilibrator operates to reestablish ambient pressure in the pressure shell for continued operation. In operation, the pinch/squeeze unit exerts radial forces on the elastomeric fluid channel. These forces act to sequentially push fluid medicament for infusion to the patient when the elastomeric fluid channel is occluded and stressed, and draw fluid medicament from the collapsible bag as the elastomeric fluid channel is unstressed.

A portable system and method for infusing liquid medicaments to a patient through an elastomeric fluid channel includes an airtight pressure shell for holding a collapsible bag of the fluid medicament to be infused. A pressure sensor connected to the pressure shell monitors decreases below ambient pressure inside the shell to determine when the sub-ambient pressure becomes insufficient to continue assisting the withdrawal of fluid from the collapsible bag to an external pinch/squeeze unit. An equilibration valve is synchronized with the pinch/squeeze unit to reestablish ambient pressure in the pressure shell for continued operation as the pinch/squeeze unit acts to sequentially push liquid medicament for infusion into the patient.

An elastomeric pump having at least one sensor for sensing changes in elongation of a bladder of the pump is provided. Also provided is an infusion assembly including an elastomeric pump having a bladder, at least one sensor for sensing changes in elongation of the bladder, and an indicator for providing one or more outputs of the sensor. The sensor may be a flexible sensor positioned in contact with the bladder of the pump, or a dielectric material may be incorporated into the material the bladder is made from such that the dielectric elastomer material of the bladder forms the sensor.

The needle is configured to project from a distal end of the housing. The reservoir is disposed in the housing and has a flexible wall. The medicament delivery device further comprises a dispensing member and a biasing member. The dispensing member is disposed in the housing and the biasing member is configured to bias the dispensing member to move in an arcuate path relative to the housing such that the dispensing member moves across the flexible wall of the reservoir to dispense medicament from the reservoir when the reservoir contains medicament.

A wearable drug delivery device and related methods are described. The wearable drug delivery device can include: a housing; a flexible bag disposed within the housing; a cannula in fluid communication with the flexible bag; and a pumping mechanism for forcing a drug from the flexible bag and into the cannula, wherein the pumping mechanism is proximate the flexible bag and includes a spring-loaded paddle or a driving bag.

Embodiments of this invention relate to a fluid delivery device. The fluid delivery device comprises a fluid reservoir for containing a fluid, a first drive mechanism configured to remove a predetermined amount of the fluid from the fluid reservoir when the first drive mechanism is actuated, a needle, a septum and a housing having an orifice. Also disclosed is a method for dispensing a fluid from a fluid delivery device into a patient.
