An apparatus for injectate delivery includes a cartridge, a linear actuator, a rotary motor mechanically coupled the actuator, and a controller coupled to the motor. The controller controls a linear motion of the actuator by controlling an electrical input supplied to the motor in a first interval during which the motor is stationary with the linear actuator engaged with the cartridge to displace an injectate in the cartridge, a second interval following the first interval during which the controller accelerates the motor from stationary to a first speed selected to create a jet of the injectate from the cartridge with a velocity sufficient to pierce human tissue to a subcutaneous depth, a third interval during which the controller maintains the motor at or above the first speed, and a fourth interval during which the controller decelerates the motor to a second speed to deliver the injectate at the subcutaneous depth.

The invention relates to a supply system having at least one outlet for connecting to an applicator instrument, and having a controller (51) that controls at least one valve (50, 50, 50, 50) such that, within an application time interval of less than 4 s, in particular less than 2 s: a) a first fluid during at least a first delivery interval (T1) with a first pressure (ph) is conveyed in a first feed line (11); b) a second fluid during a second delivery interval (T2) following the first conveying interval (T1) is conveyed with a second pressure (pz) in a second feed line (23); and c) the first fluid, during at least a third delivery interval (T3), is conveyed with a third pressure (pl) in the first feed line (11).

A material for an injection nozzle is molded into a form that includes a sacrificial tip around the nozzle exit orifice. The sacrificial tip is then machined away using any suitable machining process to expose the exit orifice. In this manner, an injection nozzle can be fabricated with favorable geometric characteristics.

The invention relates to an instrument head, comprising: an exit opening (23); a first feed line (11) for the feed of a first fluid; a second feed line (12) for the feed of a second fluid; a reservoir (24) for storing the fluid fed via the second feed line (12); wherein the reservoir (24) is in fluid communication with the first feed line (11) and/or is adapted to be brought in fluid communication with the first feed line (11) via at least a valve (25) arranged in the instrument head, to deliver fluid stored in the reservoir (24) via the exit opening (23).

A needle-less injector having a housing comprising two or more separate chambers defined within said injector for containing liquid to be injected wherein each chamber comprises 1) a liquid outlet positioned at the front end of the injector; and 2) a dispensing member in contact with the liquid in said chambers and movable in a first direction to reduce the volume of said chamber to cause the liquid contained therein to be expelled through said liquid outlet, wherein the needleless injector further comprising a drive means for actuating said injector, wherein the distance between the liquid outlet for each of said chambers is at least 20 mm.

An injection device for use with a cartridge containing an injectate includes a housing. The housing includes an end wall at its distal end and an inner wall. The inner wall extends in a direction from the proximal end of the housing to the distal end of the housing and separates a first chamber from a second chamber in the housing. The housing includes a first opening disposed in the end wall and is in fluid communication with the first chamber. The housing includes a second opening is in fluid communication with the second chamber. A coupler is disposed in the first chamber for coupling to the cartridge. The first opening and the second opening are in fluid communication via a channel for transfer of fluid between the first chamber and the second chamber.

A disinfection tip is described for disinfecting a threaded connector of a syringe. The disinfection tip includes a cylindrical outer housing, a substantially cylindrical inner housing extending from a distal wall of the outer housing, a distal chamber defined by the outer sidewall of the inner housing, the inner wall of the outer housing and the distal wall of the outer housing, the distal chamber being in fluid communication with the cavity, the distal chamber retaining a disinfectant or antimicrobial agent when the disinfection tip is disposed within an outer wall of the luer connector of the syringe and, at least one jet orifice radially disposed on the inner rim in fluid communication with the distal chamber allowing for fluid to pass from the distal chamber through the jet orifice directing the disinfectant or antimicrobial agent towards a center of the outer housing when the disinfection tip is further inserted into the luer connector of the syringe, the insertion of the disinfection tip causing the volume of the distal chamber to reduce and expel disinfectant or antimicrobial agent through the at least one jet orifice.

Aspects of the present invention relate to a nozzle for a syringe for injecting blood plasma into a sinus cavity within a patients mouth. The nozzle comprises a body having a passage extending through the body along a longitudinal axis of the nozzle. The passage extends from a proximal end to a distal end of the body and an inlet to the passage is located at the proximal end of nozzle for receiving blood plasma from the syringe. An outlet from the passage is positioned at the distal end of the nozzle for distributing blood plasma in the sinus cavity. The outlet comprises an outlet aperture located on a distal tip of the nozzle and at least one exit gate extending from the passage through the distal end of the body. Aspects of the present invention relate to a thumb tab for plunging a plunger of a syringe, the thumb tab comprising a base portion for attachment to the plunger and a resiliently deformable spring element extending from the base portion. The spring element is moveable from a relaxed position to a compressed position in response to a user pressing on the spring element to depress the plunger within the syringe, in use. Aspects of the present invention relate to an osteotome, the osteotome comprising: a body having a longitudinal axis; the body having a distal end, and the body comprising a distal shoulder extending around an external surface of the body; the distal end of the body extending distally from the distal shoulder, and wherein the distal end of the body tapers in a distal direction from the distal shoulder towards a distal tip along the longitudinal axis.

This invention provides an insulin injection device, comprising: a wearable module, a detection module and a drug administration module, wherein the wearable module is used for fixing the detection module and the drug administration module to a body of a user; the detection module is used for detecting a blood glucose concentration of the user, determining a dose of required insulin according to the blood glucose concentration, generating a corresponding drug administration instruction according to the dose of the required insulin, and sending the drug administration instruction to the drug administration module; and the drug administration module is used for storing the insulin and injecting a corresponding dose of insulin into the body of the user according to the drug administration instruction. The device can bring convenience to patients regarding usage.
