Embodiment Construction

[0028] As mentioned in the background section, current injection pens are inconvenient to adjust the dose during injection.

[0029] Based on the above research, the embodiment of the present invention provides a fine-tuning injection pen. When adjusting the metering before injection, the digital cylinder, the adjustment cylinder, the ratchet connecting ring, the ratchet cylinder and the button connector are driven by rotating the knob. And the button moves upwards at the same time, in which the adjustment cylinder performs thread lead rotation movement, the adjustment cylinder and the ratchet connecting ring are ratchet assemblies, and due to the reaction force of the button spring, during the adjustment process, the ratchet connecting ring and the ratchet cylinder There will be a "click" sound under the action of the ratchet. When adjusting, the adjusted dose can be observed through the window. If the adjusted dose is too much, the dose can be recalled by turning the knob. Du...

Abstract

The invention discloses a fine adjusting injection pen. The injection pen comprises a differential screw drive mechanism, a dose adjustment mechanism, a shell and an injection mechanism, wherein the differential screw drive mechanism comprises a push rod, a push rod nut, a rotary positioning ratchet, an adjusting lever and a ratchet cylinder; the dose adjustment mechanism comprises a knob, a digital tube, an adjusting cylinder, a ratchet connecting ring and an adjusting connecting cylinder, and the adjusting lever is sleeved with the ratchet connecting ring; a differential screw is arranged in the shell in a drive mode, the shell is provided with a window, and the shell is internally provided with a refill holder; the injection mechanism comprises a key connecting piece, a key, a key spring and the like. In the process of adjusting, the contact part of the ratchet connecting ring and the ratchet cylinder makes a 'click' sound under the action of the ratchet, and in the process of retracement, a 'click' sound also be made; through the sounds, a user can be given with a voice warning, and furthermore, combined with a visual warning of the window, the dose adjustment is facilitated. In addition, the fine adjusting injection pen can be used repeatedly, and compared with a traditional direct-push-type injection pen, the injection precision can be effectively improved by transforming spiral motion into linear motion.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fine-tuning injection pen. Background technique [0002] Traditional drug injection usually requires professional medical personnel to use disposable sterile syringes for injection, which will inevitably produce glass debris and waste of drug solution during the injection process. [0003] In order to solve the above problems, a self-injecting injection pen has emerged as the times require. When injecting, you only need to put the medicine bottle into the injection pen and connect the matching needle to realize self-injection. The whole injection process will not produce Glass shards, the liquid medicine will not be transferred and will not be exposed to the air, so the safety of the medicine can be guaranteed and the convenience of the medicine can be improved. [0004] It can be applied to various first aid and chronic diseases such as diabetes, etc., to help patient...
