A precision steerable and angled medication delivery system is disclosed. The system may direct a delivery mechanism in connection with a control syringe to delivery sites within a patient's body. In this manner, therapeutic injections may be performed at precise locations as desired. The precision steerable and angled medication delivery system may have a structure configured to orient at least a portion of an elongate penetrative feature such as needle to be at least partially non-parallel to a longitudinal axis, further facilitating performance of therapeutic injections at precise locations.

A multiple carrier injection system includes an adapter, having at least one arm, and a pen needle assembly. The pen needle assembly includes a hub retaining a needle and a bullet having a cover to seal the bullet, where the bullet encloses the hub in a first position. The arm engages the adapter to the hub, and the arm causes the hub to rotate within the bullet to move the hub into a second position.

A needle assembly for medical or surgical use is disclosed, such as for hemodialysis. A representative needle assembly comprises an outer needle assembly and an integral needle tip protector. A representative outer needle assembly comprises: an outer needle comprising: a first lumen; a first aperture with a sharp needle tip at a first distal end of the outer needle; and a second aperture arranged opposite the first aperture. In another embodiment, the outer needle has a longitudinal slot and the integral needle tip protector includes a sliding connector which is slidable in the longitudinal slot. The integral needle tip protector is arranged within the first lumen and moveable between a retracted configuration and an extended configuration, and comprises: a needle tip cover arranged to shield the sharp needle tip in the extended configuration, the needle tip cover having a smooth or beveled distal surface forming a blunt tip.

An injection device includes a cylinder having a cavity for receiving a liquid. A passage is connected to the cavity for inflow and/or outflow of the liquid. The passage can be connected to an injection component. A shut-off valve has a valve body and a flexible sealing ring with an opening. The valve body, proceeding from a release position in which the passage is freed, is at least partially movable through the opening of the sealing ring to a blocking position in which the valve body engages behind the opening so that movement of the valve body to the release position is blocked and the passage is sealed off against proximally directed flow. An adapter body is connected to the cylinder. The shut-off valve is arranged at a proximal end of the adapter body and at a distal end of the cylinder. The device can be used in a syringe.

A smart drug injection device is disclosed, comprising a main body, a circuit board, a display, a syringe and a transmission mechanism; the main body comprises an accommodating space and a power button; the circuit board comprises a control unit and a storage unit; the transmission mechanism comprises a motor, a screw rod, a propelling block and a movable clamp, with the control unit electrically connected to the storage unit, the power button, the motor and the display, the motor connected to the screw rod, the propelling block movably arranged on the screw rod, the movable clamp disposed at one end of the propelling block and movable between two positions; the syringe is on one side of the main body and comprises a cylinder and a needle holder, one end of the cylinder has a needle and the other end is assembled with the needle holder.

This medical container includes a tubular barrel defining a reservoir for a medical product and a longitudinal distal tip defining a fluid path in communication with the reservoir in order to allow the medical product to be expelled from the medical container. The distal tip and the barrel are made of glass and the distal tip is provided with a thread, the thread being configured to connect the distal tip to a connecting element having a complementarily shaped internal thread.
