Description

Nursing teaching aid

Technical Field

The invention relates to the technical field of nursing teaching, in particular to a nursing teaching aid.

Background

The nursing is a process beneficial to the rehabilitation of patients, acupuncture is a common way in nursing, acupuncture means that a needle is inserted into the body of a patient at a certain angle under the guidance of the theory of traditional Chinese medicine, and acupuncture techniques such as twisting, lifting and inserting are used for stimulating specific parts of the human body so as to achieve the purpose of treating diseases, for example, a professional medical nursing injection teaching instrument disclosed by the publication number of CN108305521B, and the acupuncture has the beneficial effects that: the device is used for a medical nursing injection teaching instrument, plays a role in supporting the rubber block and simultaneously enables the fixing plate to rotate; the rubber block can be fixed through the fastening bolt, so that the rubber block is convenient to install and replace; the injection experiment can be carried out through the rubber block, so that the injection result can be conveniently observed; the rubber block can be supported, so that the stability of the rubber block is improved, and the operation is convenient; the whole injection teaching instrument is simple in structure, can be adjusted, can simulate injection training through the rubber block, can obtain a training result by observing the rectangular through hole, avoids causing injury to a human body, can also recover solution, is simple to operate and convenient to use, and has the beneficial effects that: it can greatly increase the interest of users and the intelligence, and can increase and accelerate the spread of traditional Chinese medicine acupuncture in China and the world. The needle bag has the advantages of wide application range, excellent characteristics and better prospect. Wherein the functionality can be increased by changing the material, and the training and learning of finger force, needle feeling and acupuncture can be completed. The materials used can improve the service life, moisture resistance and drop resistance, and the module can be replaced. The needle bag of the invention can enable the needle to be trained without breaking on the basis of increasing the interest. Different modules can be manufactured according to different materials at the later stage, and the functions can be added by purchasing different modules by a user; the shape of the nursing teaching aid can be changed, and the interestingness is increased, so that the existing nursing teaching aid meets the use requirements of people, and the following problems still exist.

In order to enable the medical student to master the acupuncture skill of acupuncture and moxibustion, the medical student generally uses a teaching aid for acupuncture and moxibustion teaching to practice so as to ensure the skill of the medical student in acupuncture and moxibustion, such as the seven points of the stomach hair in the acupuncture points of the human body, which are from the depression of the lower edge of the xiphoid process of the human body, one point of one inch directly, three points totally, and two points of five points by one inch, one inch and five points are opened aside, when the practitioner exercises acupuncture and moxibustion, the normative needle holding method and the depth of the acupuncture and moxibustion must be mastered skillfully, but the traditional acupuncture and moxibustion teaching aid cannot limit the needle holding method of the practitioner and cannot give an early warning to the depth of the acupuncture and moxibustion of the practitioner when the practitioner exercises, so that the practitioner cannot accurately judge the accuracy of the acupuncture and moxibustion depth, thereby greatly reducing the efficiency of the practitioner's practicing proficiency, and referring to the acupuncture and moxibustion bag disclosed as CN107731075B in the above-mentioned comparison patent, it can only increase the interest of the practitioner, the efficiency and precision of the practice of the practitioner are not substantially changed, so that a nursing teaching aid is urgently needed to solve the problem that the device can not only solve the problem that the needle holding manipulation of the practitioner is not standard enough during the needle insertion process, but also can be matched with the partial structure to warn the practitioner whether the depth of the needle insertion is correct or not.
