9 results about "Hypodermic needle" patented technology

An apparatus for the automated filling of cartridges of e-vapor devices may include a filling drum configured to receive at least one cartridge of an e-vapor device. The apparatus may additionally include a needle assembly including at least one hypodermic needle. The needle assembly is configured to transition between a lowered state and a raised state. The lowered state is where the hypodermic needle is moved down into the cartridge, while the raised state is where the hypodermic needle is lifted up and away from the cartridge. The apparatus may further include a pump assembly configured to pump a pre-vapor formulation into the cartridge when the needle assembly is in the lowered state. The pump assembly may include a variable amplitude cam system configured to adjust an amount of the pre-vapor formulation for pumping to the cartridge without changing start and stop times for the pumping.

A dosage verification system for use prior to administering an injection of a medicinal fluid drawn into the fluid chamber of a medical syringe, the system comprising a medical syringe having a barrel with an outwardly facing, flat indicia display surface, a plunger having a plunger seal disposed inside and slidably engaging an inwardly facing wall of the barrel and a plunger handle projecting rearwardly from the barrel, and a hypodermic needle projecting forwardly from the barrel, all in combination with an imaging device configured to view and selectively capture, store or transmit a digital image of the plunger position relative to the barrel when a dose of the medicinal fluid is drawn into the fluid chamber of the barrel prior to an injection to verify and provide a record of the dosage drawn, and to alert a user prior to injection when an incorrect dosage is drawn into the fluid chamber of the syringe.

Medical devices including an integrated dressing pad assembly. A medical device comprises a hypodermic needle having a distal tip configured to be inserted into a patient at an insertion location and a proximal end attached to a needle hub. An integrated dressing pad assembly is mounted to and positioned with respect the medical device or packaging so that the integrated dressing pad assembly is configured to be slidably engaged along the length of the hypodermic needle and applied to a patient at the insertion location when the medical device is used and the hypodermic needle is removed from the patient.

In the field of medical sharps, particularly subcutaneous injection needles, there is a need for improved needle assemblies. A needle assembly (10;80;100;110;120;130) for engaging with a syringe (58;90) having an elongated hollow syringe body (56) in which a plunger (34;88) is slidably received comprises a needle assembly body (12) having a subcutaneous injection needle (14) coupled to the needle assembly body (12) and extending from the distal end (16) of the needle assembly body (12). The needle assembly (10;80;100;110;120;130) also includes an actuator valve (18;132) movably received within the needle assembly body (12) and formed to define a propellant storage space (22;122). The actuator valve (18;132) is movable between a closed position in which the propellant is held under pressure in the propellant storage space (22;122) and an open position in which the propellant is released from the propellant storage space (22;122) and causes the needle (14) to shroud.

In the field of methods and apparatus for administering drugs, there is a demand for improved closed-loop transfer devices. A closed-loop transfer device (10) comprises a syringe (12) having an elongated hollow syringe body (14), in which a plunger (16) is slidably housed, defining a drug chamber (18) whose size changes depending on the degree of insertion of the plunger (16) within the syringe body (18). The closed-loop transfer device (10) also comprises a needle assembly (28;300) having a needle assembly body (30), to which a subcutaneous injection needle (32) is fixedly attached. The needle assembly body (30) is coupled to the syringe body (14) and maintains fluid communication between the internal conduit (40) of the subcutaneous injection needle (32) and the drug chamber (18). In addition, the closed-loop transfer device (10) also comprises a shield assembly (42) having a shield body (44). The shield body (44) is movably coupled to the syringe body (14), thereby allowing the shield assembly (14) to selectively operate to surround the needle (32). The shield body (44) and the syringe body (14) are provided with mutually cooperative forming parts for restricting the movement of the shield assembly (42) relative to the syringe (12) through a series of positions (200, 210, 220, 230, 240, 250, 260) corresponding to different operating states of the device (10).

In the field of medical sharp instruments, particularly in the field of subcutaneous injection needles, an improved needle assembly is needed. A needle assembly (10, 80, 100, 110, 120, 130) for engagement with a syringe (58, 90) having an elongate hollow syringe body (56) within which a plunger (34, 88) is slidably received includes a needle assembly body (12) having a hypodermic needle (14) coupled with the needle assembly body to extend from a distal end (16) of the needle assembly body. The needle assembly (10, 80, 100, 110, 120, 130) also includes an actuator valve (18, 132) movably received within the needle assembly body (12) and formed to define a propellant storage volume (22, 122). The actuator valve (18, 132) is movable between a closed position, in which propellant is held under pressure in the propellant storage volume (22, 122), and an open position, in which propellant is released from the propellant storage volume to shield the needle (14).

In the field of drug delivery methods and devices, improved closed system transfer devices are required. A closed system transfer device (10) includes a syringe (12) having an elongate hollow syringe body (14) within which a plunger (16) is slidably received to define medicament chambers (18) of different sizes depending on the extent of insertion of the plunger within the syringe body (18). The closed system transfer device (10) also includes a needle assembly (28; 300) having a needle assembly body (30) to which the hypodermic needle (32) is securely secured. The needle assembly body (30) is coupled with the syringe body (14) to maintain an internal conduit (40) of the hypodermic needle (32) in fluid communication with the drug chamber (18). In addition, the closure system transfer device (10) also includes a shroud assembly (42) having a shroud body (44). The shroud body (44) is movably coupled with the syringe body (14), whereby the shroud assembly (14) is selectively operable to enclose the needle (32). The shroud body (44) and the syringe body (14) include mutually cooperating formations to constrain movement of the shroud assembly (42) relative to the syringe (12) through a series of positions (200, 210, 220, 230, 240, 250, 260) corresponding to different operating conditions of the device (10).
