Quick pregnancy examination scale

Abstract

The invention discloses a quick pregnancy examination scale, which belongs to the field of medical articles and comprises an outer scale, an inner scale, a positioning slide ring and a vernier. The outer scale is a tubular structure with a through groove in the middle, the inner scale is cylindrical, is nested in the outer scale and is slidably connected with the outer scale, the vernier and the positioning slide ring are slidably sleeved on the outside of the outer scale, and the positioning slide ring is located on the left side of the vernier. The quick pregnancy examination scale is simple in structure, convenient in manufacture, low in cost, small in size, light in weight, convenient in operation and carrying, high in loaded data volume and fast and convenient in inquiry, greatly reduces memory burden of medical staff, can be used for inquiring relevant data rapidly and accurately, and improves work efficiency of the medical staff. Data are checked by the aid of an amplifying lens and are clear, accuracy is improved, and work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a quick detection ruler, in particular to a quick detection ruler during pregnancy, which belongs to the field of medical supplies. Background technique [0002] At present, there are two types of measuring tools for pregnancy health care in clinical use: the rotary disc type and the ruler type. Although they provide a lot of convenience for clinicians, they are difficult to popularize because of the following disadvantages: 1. The disc is large in size and easy to carry. inconvenient. 2. Since the circumference of the disc is smaller as it gets closer to the center of the circle, it cannot accommodate more data, and the physiological constant indicators provided are less, which cannot fully reflect the growth and development of the fetus in the uterus. Accommodating more data leads to fewer functions of this type of product. In addition to calculating the pregnancy period and expected date of delivery, it is difficult for cli...

[0002] At present, there are two types of measuring tools for pregnancy health care in clinical use: the rotary disc type and the ruler type. Although they provide a lot of convenience for clinicians, they are difficult to popularize because of the following disadvantages: 1. The disc is large in size and easy to carry. inconvenient

2. Since the circumference of the disc is smaller as it gets closer to the center of the circle, it cannot accommodate more data, and the physiological constant indicators provided are less, which cannot fully reflect the growth and development of the fetus in the uterus. Accommodating more data leads to fewer functions of this type of product. In addition to calculating the pregnancy period and expected date of delivery, it is difficult for clinicians to make an accurate diagnosis of fetal growth and development, which often delays the timing of treatment. Therefore, this type of measurement Tools are not adapted to the needs of clinical diagnostic services
