Embodiment Construction

[0023] Some embodiments will now be described with reference to the drawings.

[0024] reference figure 1 , The actuator assembly 10 and the cartridge holder 20 are provided for injecting the solid dosage formulation into the human or animal body.

[0025] The actuator assembly 10 includes a body part 12 and a box mounting part 14. The body portion 12 houses a mechanism for operating the actuator. The cartridge mounting portion 14 is configured to receive the cartridge 34 including the solid dosage formulation in the bayonet fitting 16 or similar structure.

[0026] Such as figure 2 As shown in, the cartridge holder 20 includes a cartridge holder body 22 opened at one end. The cartridge holder insert 24 can be inserted into the open end of the cartridge holder body 22. The cartridge holder insert 24 includes the cartridge storage portion 26 of the storage cartridge 34. The box storage portion 26 is defined by three curved forks 28 that are biased to abut against the box 34 to pu...

Abstract

The invention relates to an injection device for injecting solid dosage formulations into the human or animal body, the injection device comprising an actuator (10) with a cartridge mounting part (14), a cartridge with a cartridge storage part A holder (20), and a cartridge selectively movable between the cartridge storage portion and the cartridge mounting portion, wherein the cartridge (34) includes a solid dose formulation, and the actuator is receivable in the cartridge holder to move the cartridge The cartridge is selectively moved between the storage section and the cartridge installation section.

Description

Technical field [0001] An injection device that is particularly suitable but not clearly suitable for injecting solid dose formulations into human or animal bodies. Background technique [0002] The solid dosage formulation can be introduced into the human or animal body at a low speed via injection or at a high speed fired from a gun. High-speed dosing is not suitable for introducing solid dosage formulations into the human body, so much effort has been made to develop a solid dosage formulation that has the required shape and material properties to help It is easy to inject into the human body. In some cases, the solid dosage formulation can be introduced into the human body by a simple method such as pushing the solid dosage formulation through the skin without the aid of tools or devices. [0003] However, in order to avoid unnecessary damage to the human body, it is desirable to introduce the solid dosage preparation by applying only the force required for passing the solid ...
