Description

Mechsler's point measuring ruler

Technical Field

The utility model relates to a human medical science measuring device, concretely relates to wheat point dipperstick.

Background

Acute appendicitis is one of the common acute abdominals in general surgery, and the Mai's point (Mc Burney point), also known as the appendix point, is an important sign of acute appendicitis. The position is located at the junction of the anterior superior iliac spine and the middle-outer third of the umbilical connecting line, and the McCloud point tenderness has important significance in the diagnosis of acute appendicitis. The medical measurement teaching aids of the dissection classes of teaching colleges and universities at the present stage are few, particularly, the tools for measuring the Mains point are also few, if the measurement is carried out on a living body by using the existing tools which are not designed for human anatomy, such as a meter ruler, a measuring tape, a protractor, a straight ruler combined device and the like, the living body is not discomfortable, the measured angle can also deviate due to factors such as breathing and shaking of the human body, and the obtained data can lack accuracy. If the position of the McLeod spot cannot be accurately measured, the following problems occur: 1. The body surface parts for describing the appendix points during the class of medical students are very fuzzy and wide, and the specific and accurate parts cannot be described by numbers, such as the length and the angle, which is not favorable for the deep learning of the students; 2. when the external inspection result of appendicitis is written on a case history in clinical work, a doctor still follows a fuzzy theory in a teaching book, cannot describe and record the body surface position in detail by using length and angle figures, and is not favorable for providing detailed operation data for a surgeon; 3. when a doctor performs an operation incision in the appendicitis excision, the doctor usually visually inspects the operation incision by taking the navel, the left and right anterior superior iliac spines and the like as marks, or judges that a Mai's point is at the middle and outer 1/3 intersection points of the connecting line of the right anterior superior iliac spine and the navel or at the right and middle 1/3 intersection points of the connecting line of the left and right anterior superior iliac spines according to the body surface projection of the appendix root, but the specific position of the appendix changes from person to person, and if the doctor only depends on the visual inspection of the Mai's point to perform the operation incision, the mode not only lacks accuracy, but also has certain risk. In addition, the existing measuring device is small in size, the scale on the upper portion of the device is small, a doctor needs to be close to a diseased part of a patient to see the measured scale when using the device, and therefore the device is inconvenient for the patient and the doctor, and the problem is solved by researching a Machs point measuring scale.
