Electronic pain sense measuring pen

Abstract

The invention discloses an electronic pain sense measuring pen, which belongs to the field of medical instruments. The electronic pain sense measuring pen is characterized by being manufactured according to a principle that electric stimulation pain is generated when a high-voltage low-current electron impulse acts on human skin. The electron impulse is generated by adopting a piezoelectric effect principle of ceramic crystals. The electronic pain sense measuring pen consists of a pen head, a shell, a trigger switch, a piezoelectricity generator and a conducting wire. The electronic pain sense measuring pen has the advantage of measuring the level of anesthesia to determine the anesthetic effect and guide the anesthesia dosage when applied to intravertebral anesthesia and nerve blocking anesthesia. The electronic pain sense measuring pen avoids inaccurate feeling of pain stimulation of a patient because of the non-constant needling force in a needle punching method, ensures that the measurement result is more accurate, and cannot burn skin and do harm to a body at the same time of safe electric stimulation, thereby eliminating pains of patients, and reducing the probability of infection and blood-source spread diseases.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an electronic pain detection pen. Background technique [0002] It is often necessary to measure the anesthesia plane during spinal anesthesia and nerve block anesthesia to clarify the effect of anesthesia and guide the dosage of anesthesia. When measuring the level of anesthesia, the traditional acupuncture method is still used at present, that is, the needle of a disposable syringe is used to stimulate the patient's skin, and the anesthesia level and effect are judged according to the patient's feeling of pain from the needle tip stimulation. When the acupuncture method is used, since the operator only grasps the acupuncture strength by feeling, it cannot be quantitatively measured with a constant strength, which will affect the patient's subjective feeling of pain from needle tip stimulation to a certain extent. In addition, because the needle tip is very sharp, it will leave s...

Problems solved by technology

When the acupuncture method is used, since the operator only grasps the acupuncture strength by feeling, it cannot be quantitatively measured with a constant strength, which will affect the patient's subjective feeling of pain from needle tip stimulation to a certain extent.

In addition, because the needle tip is very sharp, it will leave some needle holes on the body surface when stimulating the patient's skin, which will bring pain to the patient and increase the chance of infection and blood-borne diseases. At the same time, the sharp needle may accidentally injure other people.

Some foreign anesthesiologists use blunt neurotip tester pins instead of disposable needles, which can greatly improve the safety of acupuncture, but the testing force is not easy to control accurately
