摘要： A manually compressible reservoir, such as a rubber bulb is provided in which a liquid medication is maintained and from which an outlet conduit extends to a selected body part. The prosthesis includes a piston for storing separately from the reservoir a predetermined dose of medication and which piston is responsive to the manual compression of the reservoir to discharge the predetermined dose and on release to automatically cause the medication to flow from the reservoir to restore a predetermined dose so that repeated operation and delivery of medication is possible.

摘要： The present invention generally provides a device for inserting needles and alleviating the discomfort associated with needle insertion. In certain embodiments, the device is suited for injecting butterfly needles and particularly butterfly needles that are attached to infusion tubing. The patient or caregiver loads a butterfly needle with tubing attached into the base of the drive plunger. The needle with tubing attached is retracted into the housing of the device by retracting the inner plunger. Once retracted, the device is activated and ready to administer a needle into the tissue of a patient. The device is then placed on the location of the skin where injection is desired. The surface that contacts the skin may be textured and may include a contact switch that causes the device to vibrate when slight pressure is applied through contact with the skin. Two trigger buttons in the housing of the device may be depressed to eject the needle at an angle essentially perpendicular to the surface of the skin into the tissue of the patient concurrently with the textured pads contacting the skin and vibrating, distracting the patient from the needle insertion. The inner plunger of the device is then depressed toward the surface of the skin to release the needle from the device. The wings and body of the butterfly may be secured to the skin, for example, with an adhesive such as tape.

摘要： A gear-driven infusion assembly is provided which has a housing, a gear assembly coupled to the housing, a shuttle assembly slidably coupled to the housing and operably coupled to the gear assembly, and a tube enclosure connected to the housing. The tube enclosure is configured to house a primary drug closure such as a syringe. The gear assembly includes a spool assembly having a pinion gear and a drive spool. When the spring rotates the drive spool, the drive spool drives the pinion gear, and the gear assembly drives the shuttle assembly. When the gear assembly drives the shuttle assembly, the shuttle assembly slides longitudinally along the housing. The gear assembly may be spring driven such that a spring rotates the pinion gear about the drive spool. An overspeed protection device is also provided which has a spool assembly including a drive spool.

摘要： Provided is a system and method for a removable syringe micro pump. The removable syringe micro pump includes a pump housing having a first end and opposite thereto an attaching end, and at least one sidewall there between, the housing having a base proximate to the first end and, the attaching end having an attacher structured and arranged to temporarily engage a syringe. At least one wave spring is nested within the housing and attached proximate to the base. The wave spring having has a compressed first position wherein the wave spring is disposed within the pump housing, and a second extended position wherein, the release of tension extends the spring normally away from the pump housing. The wave spring has a diameter pre-selected to pass within a barrel of the engaged syringe. And engage a plunger seal of the syringe. An associated method of use is also provided.

摘要： Provided is a system and method for a high flow at low pressure infusion system needle set for delivering a liquid from a reservoir to a patient. More specifically, provided is a high flow at low pressure infusion system needle set including a flexible tubing element having a first length and a first end structured and arranged to connect to the reservoir, and a second end opposite thereto, the flexible tubing element having a first internal diameter. A needle having a second length and a second internal diameter is coupled to the second end of the flexible tubing, the needle having a first portion providing a sharpened distal end for penetration of the patient's tissue and a second portion providing a second end in fluid communication with the second end of the flexible tubing element, the first portion and second portion generally normal to each other. The second end of the needle has an outside diameter, the flexible tubing element having an average first internal diameter along the first length, the average first internal diameter at least 25% larger than the outside diameter of the second end of the needle. An associated method of use is also provided.

摘要： A device, noteworthy by its compact construction, portability and use of a constant torque spring to dispense liquid under a uniform force, in which binding due to possible rotative movement in the slide that is powered by the torque spring is obviated, so that the slide tracks properly during liquid-dispensing service of the device, This is in contrast to torque spring-operated prior art devices in which special precautions were required to neutralize the turning movement unavoidably resulting when the torque spring assumed its characteristic helical coils during its functioning.

摘要： Using latent heat of vaporization of a selected evaporative fluid, an abnormally elevated testicular temperature is effectively diminished so as to contribute to obviating male infertility due to poor semen quality. Moreover, the evaporative method employed, and the device using such method, are particularly appropriate in that the cooling effect is achieved over a prolonged period so as to facilitate achieving the desired medical result, whereas merely diminishing the testicular temperature for a short duration would not be medically effective.
