Painless electric skin injection device

Abstract

The invention discloses a painless electric skin injection device, which comprises: a shell comprising a rear end main body and a front end handle; an injection module comprising a driving device, a first power supply module, an injector detachably mounted in the front end handle and a first trigger device, wherein the first power supply module is electrically connected with a driving device and the first trigger device; a cold compress module comprising a second power supply module installed in the rear end main body, a refrigeration device, a first heat conduction part located in the shell, a cold compress module located at the foremost end of the front end handle and a second trigger device installed on the front end handle, wherein the first heat conduction part is connected with the refrigeration device and the cold compress module, and the second power supply module is electrically connected with the refrigeration device and the second trigger device; and a control module mounted on the rear end main body and connected with the injection module and the cold compress module, wherein the driving device can drive the needle of the injector to penetrate through the cold compress module. According to the invention, parameters required by injection can be independently controlled, and whole-course painless injection is achieved.

Description

technical field [0001] The invention relates to the technical field of injection devices, in particular to a painless electric skin injection device. Background technique [0002] As the largest organ in the human body, skin is composed of epidermis and dermis, and contains accessory organs (sweat glands, sebaceous glands, hair follicles, etc.). As the outermost structure of the skin, the epidermis is in direct contact with the external environment and is composed of stratified squamous epithelium, which is thin and does not contain blood vessels. From the basal layer to the surface, it can be divided into 5 layers, namely, basal layer, spinous layer, granular layer, transparent layer and stratum corneum, which have the functions of preventing the outflow of tissue fluid, anti-friction and anti-infection. The dermis is composed of dense connective tissue, which is the papillary layer and the reticular layer in order from shallow to deep. The papillary layer is connected to...

Problems solved by technology

However, the additional anesthesia process not only greatly increases the treatment time, but also cannot completely avoid the pain problem during treatment

In addition, due to drug problems, there is a certain chance of allergic reactions, which often make patients feel fearful.

Bleeding problems may lead to skin bruising after injection, affecting immediate postoperative effects and work and life
