Angled syringe patch injector

A syringe cartridge comprising a reservoir part and an extension extending from said reservoir part, said extension defining a fluid path and comprising a molding and a first needle extending from said molding, the extension turning to a finite angle with respect to an axis of said reservoir part and wherein at least part of said first needle is likewise at said finite angle, at least some of said part of said first needle at said finite angle being enclosed within said molding of said fluid path. A drug delivery device may be used with the cartridge and includes a skin-contacting surface. In use the longitudinal axis of the interior of the cartridge may be disposed substantially parallel to the skin-contacting surface.

Drug Delivery Device For Drug Suspensions
20200030550 · 2020-01-30 ·

A drug delivery device is provided herein, the device including a reservoir for containing a medicament. The medicament includes a suspension of solids in a liquid carrier. The device also includes a needle having a distal end for injection into a patient, a proximal end in communication with the reservoir, and a lumen extending between the distal and proximal ends. A path is defined from the reservoir to the distal end of the needle through the lumen, the path having an inner diameter that decreases in a proximal to distal direction along at least a portion thereof. Advantageously, with the subject invention, a flow path may be defined which provides a more gradual transition in diameter from the reservoir to a distal tip of the needle. In this manner, changes in velocity of the suspension may be less abrupt than in the prior art, thus better maintaining solid particles in the suspension.

SYRINGE TYPE EJECTION DEVICE
20200030552 · 2020-01-30 · ·

A syringe type ejection device capable of reducing an amount of residual liquid is provided. A syringe type ejection device includes: a barrel; a nozzle disposed to face the barrel; and a core inserted in the nozzle, the barrel having a large-diameter portion provided with a discharge space for discharging liquid, the nozzle being provided with a holding space for holding the core, the holding space being in communication with the discharge space, and the core being inserted in the discharge space.

Plastic stopper

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.

Injection device

An injection device for delivering a liquid composition, including a generally elongated housing, arranged to hold an exchangeable cartridge containing the liquid composition. The housing includes a drive device, and a plunger rod connected with the drive device and connected to a plunger within the cartridge, when the cartridge is held at the housing, for driving the plunger within the cartridge. The plunger includes a rod connector connected with a front end portion of the plunger rod. The rod connector comprises a rod stop portion, wherein there is a longitudinal play between the plunger rod on one hand and the entrance opening and the rod stop portion on the other hand, thereby enabling the front end portion to move back and forth between the entrance opening and the rod stop portion without moving the plunger.

Syringe assembly with inverse delivery

A reduced profile syringe assembly is provided that includes an overall profile that is substantially similar to a profile of a syringe barrel. The syringe assembly includes a plunger rod that is significantly disposed within the syringe barrel when filled for use, with the plunger rod adapted to be retracted from the syringe barrel during dispensing of contents of the syringe barrel.

SYRINGE DESIGN FOR CYCLING PARTICULATE SUSPENSIONS
20240100255 · 2024-03-28 · ·

The present disclosure pertains to a syringe comprising: a syringe barrel having an open proximal end that opens into an interior having a cylindrical wall and an angled distal surface terminating at an outlet; a plunger rod; and a plunger seal, a proximal end of the plunger seal configured to be attached to a distal end of the plunger rod, and a distal end of the plunger seal configured to be inserted into the interior of the syringe barrel through the open proximal end, the plunger seal forming a seal with the cylindrical wall of the interior of the syringe barrel, and the distal end of the plunger seal terminating at an angled distal surface, wherein the angled distal surface of the syringe barrel is more acute than the angled distal surface of the plunger seal. The present disclosure also pertains to kits containing such a syringe.

PATCH INJECTOR WITH SLIDABLE JOINT
20190374719 · 2019-12-12 ·

An injector including at least one fluid reservoir having a needle, a surface attached to skin and coupled to the fluid reservoir by at least a first joint and a second joint at least a portion of one of the joints being slidable or having interlocking arms. At least a portion of a path of translation of a slidable portion of the first joint and a portion of a path of translation of the second joint are angled in respect to each another.

Low Dead Volume Adaptor for a Syringe
20240131261 · 2024-04-25 ·

An adaptor for a syringe including a shaft with a lumen and a seal. The shaft is sized and shaped to be inserted in the lumen of the syringe tip and create a seal with the opening of the syringe tip, and the seal is sized and shaped to be inserted into the needle hub and create a seal with the needle hub, such that the adaptor reduces the interior volume of the lumen of the syringe tip and the needle hub that is filled with medicament contained in the syringe. Also, an adaptor assembly comprising the adaptor and a delivery housing to which the adaptor is attached, a syringe body including the adaptor, a needle assembly including the adaptor, and a syringe including the adaptor. Further, a method of reducing the dead volume of a syringe in which the adaptor is provide in the syringe as described above.
