Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Pain detection in current clinical work generally requires that several factors or requirements be met or met: firstly, a sharp and low-injury inspection tool is adopted in the pain sensation physical examination process to increase the inspection sensitivity; secondly, in order to avoid pain stimulus difference caused by different subjective examination intensities of the examiners during the physical examination process, the examinees should be given pain stimulus with the same strength intensity as much as possible; most importantly, continuous patient physical examination is often performed in clinical work, and a plurality of pain examination needles are required to be used without crossing and to be recycled immediately. At present, a plurality of medical instruments related to examination are innovated, the technical advantages of the medical instruments are mainly focused on the comprehensiveness of the examination instruments, and corresponding local technology research and development are carried out in consideration of the conditions of pressure application such as pain stimulation and the like, alcohol disinfection and cross use prevention and the like. However, in the actual clinical examination, probably because the design of the multifunctional physical examination tool cannot achieve the accuracy and the use effect of a single examination tool, no multifunctional physical examination tool is generally accepted by clinicians at present. The pain sensation physical examination needle with equal pressure is poor in portability due to the fact that a metal ball and the like are needed; alcohol disinfection physical examination needles also do not completely inactivate some specific microorganisms and proteins. Therefore, the technical inspectors are rarely used by clinicians in practical work. In addition, for the pain sensation physical examination, due to the difference between the age of the patient and the pain sensation of the patient, the pain stimulation level cannot be effectively achieved by using tools such as a cotton swab, a plastic examination needle and the like, so that the accuracy of the pain sensation physical examination cannot be ensured. The single reuse of the existing pins for physical examination in clinic has the risk of cross infection, and a plurality of pins are inconvenient to carry and carry out sharp instrument recovery. Based on the problems in the prior art, the pain sensation physical examination pen aims to be closer to clinical work requirements, improves and innovates the pain sensation physical examination tool aiming at the defects of the pain sensation physical examination process, and realizes the pain sensation physical examination pen integrating use and recovery, low cross infection risk and convenient carrying.
