Accurate trace-amount acupoint injection pen

Abstract

The invention discloses an accurate trace-amount acupoint injection pen which comprises a pen shell, an injector, a driving device, a push rod, an inductive sensor, a triggering circuit, a triggering device, a control panel, a control circuit board and a power supply.The driving device, the push rod and the injector are sequentially arranged in the pen shell from top to bottom, the driving device is connected with one end of the push rod, and the other end of the push rod abuts against the tail end of an injector piston.The inductive sensor is arranged on the inner wall of the pen shell.The control circuit board and the power supply are arranged at the upper portion inside the pen shell, and the control panel is arranged on the outer surface of the pen shell.The accurate trace-amount acupoint injection pen is different from a common muscle injector and can easily complete two actions of post-transdermal suction and injection.Even if an unskilled person uses the injection pen, the injector does not shake and shift, medical negligence is effectively prevented, and the accurate trace-amount acupoint injection pen facilitates large-area popularization and usage of an acupoint injection technology.The accurate trace-amount acupoint injection pen achieves safer, more accurate and trace-amount acupoint injection and is easy to operate and popularize.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a precise micro-acupoint injection pen. Background technique [0002] Acupoint injection is developed through the organic combination of traditional acupuncture techniques and modern medicines, which can quickly relieve clinical symptoms of patients, so it is widely accepted by doctors and patients. However, there is no special acupoint injector and device for human body acupoint injection on the existing market. Existing acupoint technology still uses traditional intramuscular injectors. Because there is still a big difference between buttock intramuscular injection and facial acupoint injection, many shortcomings have been found in clinical application: ①Different from ordinary intramuscular injection, the position is relatively fixed, and acupoints are distributed throughout the body during acupoint injection For various parts, traditional syringes are not easy to h...

Problems solved by technology

Existing acupoint technology still uses traditional intramuscular injectors. Because there is still a big difference between buttock intramuscular injection and facial acupoint injection, many shortcomings have been found in clinical application: ①Different from ordinary intramuscular injection, the position is relatively fixed, and acupoints are distributed throughout the body during acupoint injection For various parts, traditional syringes are not easy to hold and operate. ②If the subcutaneous nerves are densely distributed when injecting facial acupoints, the depth should be within a safe range. Traditional syringes tend to vibrate up and down during fine operations, which can damage muscle tissue and nerves. ③Acupoint injections For different acupoints, the injection volume is required to be more precise each time. Traditional syringes are operated by visual inspection, and too much or too little may affect the curative effect or accident. , it is easy to be too deep and too shallow to affect the curative effect or accident ⑤ When the traditional syringe is used for acupoint injection, the piston movement is too long. Acupoint injection is generally multi-point precise operation, which is relatively difficult. Long-term use may easily cause operator muscle fatigue, hand Trembling, prone to medical accidents ⑥Existing products do not have special acupoint injection devices and standard acupoint injection needles, and needle penetration is painful. This action needs to change gestures, which may cause the syringe to shake and shift if the operation is unskilled, and medical accidents may occur.
