The invention relates to an injection inducer device for use with a conventional injection syringe prefilled with a liquid medicament or preloaded with a soft capsule containing a liquid medicament. The device includes a seal preloaded in a front adapter end of the injection at position close to an injection opening of the adapter end and formed with a recessed guide groove. The device further includes a removable needle mounted at its front end with an adaptive cover, so that the removable needle can penetrate through the seal along the guide groove to enter a storage chamber of the injection syringe. The seal has a length in the longitudinal direction greater than the bevel length of the removable needle. The invention constitutes a substitution for the conventional medication bottles by virtue of the advantages of high portability, light weight, low frangibility, and high endurance for long distance transport.

Medicant mixing/administration systems are provided that can include: a medicant vial; a syringe assembly comprising a barrel and a piston; a protective material supporting the syringe assembly and medicant vial; and a member within the system, the member separating the piston of the syringe assembly from the medicant vial. Systems are provided that can include: a syringe assembly comprising a barrel and a piston; having a forward end and an opposing back end; a protective material supporting the syringe assembly; and a needle housing coupled to the protective material. Medicant mixing/administration methods are also provided that can include, within a package, sufficiently clearing a restraining member from between a medicant vial and syringe plunger to pierce the medicant vial with a piercing structure coupled to the syringe plunger, the piercing providing medicant from the vial to the syringe assembly. Additional methods can include, upon opening a package containing a syringe assembly, extending a needle housing from the package.

Syringe tip caps are described herein. Such syringe tip caps may include a cup, a cap, a locking feature, a peelable seal and an absorbent material. The cap having locking features and a chamber appropriately sized to adapt to and interlock with an annular wall of the cup.

A multi-use drug delivery device for extended use, wherein the multi-use drug delivery device comprising a multi-use main portion (310) and a single-use flow conducting device (360) adapted for conducting drug to the subcutaneous tissue of a subject, wherein the change from a connected configuration to an unconnected configuration of the main portion and the flow conducting device is through the intermediate configuration. The intermediate configuration comprises an equalizing channel defining an equalizing flow path (304) different from an unintended flow path (303). The equalizing channel is adapted for equalizing the fluid pressure in a fluid communication volume (301) to the fluid pressure in the external environment, upon changing the configuration from the connected to the intermediate configuration and thereby expanding an internal volume, whereby an equalizing fluid flow along the equalizing flow path is larger than an unintended flow along the unintended flow path, whereby equalization of the fluid communication volume is provided with a reduced risk of introducing microorganisms from the flow channel (362) into the reservoir (311).

A syringe assembly includes a plunger assembly, a syringe body, and a needle. The plunger assembly includes a plunger rod, a spring, a plunger base, and a plunger plug. The plunger rod includes a first end member having a first stepped part positioned in an inner wall thereof, a second end member, and a first accommodating room. The plunger base includes a plunger body, a projection, a second stepped part, a plunger member, and a locating member. The plunger body is received in the first accommodating room, and the projection abuts against the first end member. The spring is arranged around the plunger body and positioned between the first stepped part and the second stepped part. The plunger plug is mounted to the second end member, and defines a fixing groove. The syringe body includes a needle cannula, a needle base, a fixing pole, and a fixing valve. The plunger assembly is received in the needle cannula. The needle base is mounted to the needle cannula. The fixing valve is received in the needle base. The fixing pole is received in the fixing valve and protrudes out of the needle base. The needle is received in the fixing pole. The syringe assembly of the present invention is prevented from reuse and accidently damage because the needle can retract into the plunger rod using restoring force of the spring.

A syringe device includes a syringe barrel and piston having a fluid passageway extending from a vial port. Another syringe device includes a syringe barrel, a piston sleeve and an insert. A channel extends along a side of the insert. A valve controls fluid communication between the channel and the syringe barrel. Another syringe device has a syringe barrel, a piston sleeve and an insert. A valve controls fluid communication between a compartment within the insert and the syringe barrel. A method of preparing a medication includes providing a component within a syringe barrel and another component within a compartment of a piston insert. A seal is over-molded onto a tip of the insert and an end of a piston sleeve. The sleeve is rotated relative to the insert to establish fluid communication between the compartment and the barrel chamber.

Syringe assemblies are provided including a partially pre-filled syringe barrel and a plunger rod that incorporates one or more retention elements on the plunger rod that prevents solution from entering a non-sterile area of the syringe when the plunger rod is pulled back. Methods to manufacture a sterilized partially-filled pre-fill syringe assembly are also disclosed.

A syringe assembly includes a barrel defining a chamber therein, pressurized sterile air in the chamber, a plunger including a piston slidable in the chamber in a sealing relation to displace a fluid in the chamber, a seal configured to retain the pressurized sterile fluid in the chamber between the piston of the plunger and the seal when the plunger is stationary, and a needle assembly extending distally from the barrel and in fluid communication with the chamber of the barrel.

A needle cap assembly for use in combination with a needle pen comprising: (i) a needle cap having a needle cannula for injecting a fluid medication into an injection site, (ii) an internal cap configured to be disposed over an injection end of the needle cap, (iii) an external cap having a cavity configured to envelop the internal and needle caps, (iv) a sealing tab configured to seal a cavity of the external cap for enclosing or housing the needle cap assembly, and (v) a cleansing swab disposed in internally of the needle cap assembly. The cleansing swab is disposed internally of the needle cap and includes an absorptive material loaded with a cleansing fluid to clean an injection site prior to injection of fluid medication.
