RETRACTABLE NEEDLE CATHETER INSERTION DEVICE
20200345974 · 2020-11-05 ·

A retractable needle catheter insertion device is provided with a cannula and a needle positioned within the cannula to assist with insertion of the cannula. After insertion of the cannula into a patient, the needle can retract into a protective sleeve that contains the needle in order to reduce the chance that a medical practitioner will be inadvertently stuck by a used needle. The needle is carried by a needle support that is slidably disposed within the sleeve. A spring biases the needle support and needle toward a retracted position, and the device also includes an activation hub that works in conjunction with the needle support to control retraction of the needle. The retraction may be activated manually by the medical practitioner or may be activated automatically. A modular system and method of manufacturing is also provided in which catheters having either manually or automatic retraction can be manufactured using common parts.

Autoinjector

An autoinjector includes a case adapted to hold a medicament container, a needle shroud telescopically coupled to the case, and a plunger slidably disposed in the case. The needle shroud is movable between a first extended position, a retracted position, and a second extended position relative to the case. The plunger is movable between a proximal position, an intermediate position, and a distal position relative to the case. When the plunger is in the intermediate position and the needle shroud is in the retracted position, the plunger abuts the case to prevent the needle shroud from returning to the extended position. When the plunger is in the distal position and the needle shroud is in the second extended position, the plunger abuts the case to prevent the needle shroud from returning to the retracted position.

Drug delivery device with protective needle cap control and device activation mechanism

A drug delivery device includes an outer body receiving a cartridge with a needle, a needle cap adapted to be coupled to the outer body and to cover the needle and a control mechanism for activating the drug delivery device. The control mechanism includes a control element received within the outer body and axially and/or rotationally movable relative to the outer body between an initial position, a first activating position, and a second activating position. The control element is coupled to the needle cap and to the cartridge, the needle cap is retained on the outer body when the control element is in the initial position, the needle cap is released from the outer body and the needle is covered by the outer body when the control element is in the first activating position, and the needle is exposed when the control element is in the second activating position.

Intravenous catheter insertion device and method of use

A catheter insertion device with a housing and an interior space. An access needle and a guide wire supported by and moveable relative to the access needle. A restraining element attached to a handle to limit the motion of the guide wire relative to the access needle. A catheter insertion device with a housing and an interior space. An access needle and a guide wire channel attached to the access needle. A guide wire supported by the guide wire channel. A handle attached to the guide wire to move the guide wire relative to the guide wire support channel. A method of introducing a catheter into a vessel by inserting a guide wire substantially contained within a housing into a vessel. Next, advance a catheter over the guide wire and into the vessel. Next, withdraw the guide wire out of the vessel and completely into the housing.

SAFETY SYRINGE
20200324057 · 2020-10-15 ·

An apparatus for use with a syringe for providing a safety syringe, the safety syringe including a plunger configured during an inward stroke to expel a substance from a hypodermic needle attached at an open end of a barrel of the syringe, the apparatus including: a biasing member configured to bias a sheath towards a closed position at least partially covering the hypodermic needle, wherein the biasing member is configured to be released at a point on the inward stroke of the plunger to urge the sheath towards the closed position.

MEDICAMENT DELIVERY DEVICE
20200324056 · 2020-10-15 · ·

A medicament delivery device is disclosed having a housing, an actuation mechanism capable of delivering doses of medicament from a medicament container and arranged with a delivery member, a shield, a guard movable within the housing, wherein the guard is operably connected to the actuation mechanism. A protective cap is releasably arranged on the housing and having a shield remover. A blocking element on the guard is movable between a blocking position and a release position and has an engagement surface to engage a proximal area of the housing. The blocking element engages with a surface of the shield remover to retain the blocking element in the blocking position. The engagement surface causes a blocking of the guard from movement and removal of the protective cap enables a movement of the blocking element to a release position when the engagement surface engages the proximal area allowing the member guard to move.

Retracting sheath detachable safety needle with moving spring
10799648 · 2020-10-13 · ·

A passive safety needle device is disclosed having a housing, a needle hub, a needle cannula, a retractable sheath, a spring to bias the retractable sheath in a distal direction to cover the distal end of the needle cannula, a radial protrusion to cause the spring to move from the proximal spring position to the distal spring position, and a catch to secure the distal end of the spring to the distal end of the housing. The spring may bias the retractable sheath in a distal direction to cover the distal end of the needle cannula. The radial protrusion causes the spring to move from a proximal spring position to the distal spring position towards the catch located at the distal end of the housing.

Safety needle devices

A safety needle device is disclosed having a hub, needle cannula, housing, tether, retractable sleeve, locking member and spring element. The tether is movably disposed in the housing, the tether having a slot with an enlarged first guide path and a narrowed second guide path extending distally from the enlarged first guide path. The retractable sleeve is configured to move from an initial position to partially expose a distal tip of the needle cannula, a retracted position to fully exposes the needle cannula, and an extended position to fully cover the distal tip of the needle cannula. The proximal movement of one or more protrusions on the retractable sleeve, rotates the tether to move the at least one or more protrusions from the enlarged first guide path of the tether to the narrowed second guide path of the tether, this rotation activating the device.
