Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a funnel chest measuring scale. Background Technique
[0002] Funnel chest is a chest wall deformity in which the middle and lower parts of the sternum and its bilateral ribs in the anterior chest wall are abnormally sunken backward in a funnel shape. The deepest part is located at the root of the xiphoid process of the sternum. At present, the funnel index (FI) is commonly used clinically to judge the degree of deformity. FI = a×b×c / A×B×C, (the longitudinal diameter of the funnel chest depression is a, the transverse diameter of the depression is b, and the depth of the depression is c; A is the length of the sternum; B is the transverse diameter of the chest; C is the shortest distance from the costal angle to the vertebral body). However, there is still no unified measuring scale in clinical measurement, and only a tape measure is used for measurement, so the error is relatively large. Therefore, in view of the above problems, a funnel chest measuring scale is designed to better meet the actual use requirements. Summary of the Invention

The cylindrical scale is vertically connected to the rectangular scale. The cylindrical scale is connected to a fixing frame, and the fixing frame is fixed on the rectangular scale. A rubber limit plate is arranged on the front side of the fixing frame.
[0005] Preferably, the rectangular scale and the cylindrical scale are slidably connected. The length of the rectangular scale is 20 cm, the width of the rectangular scale is 1 cm, and scale lines are arranged on the rectangular scale. Through the function of the rectangular scale, it is convenient to measure the transverse diameter of the chest and the length of the sternum. With the sliding function between the rectangular scale and the cylindrical scale, the position of the cylindrical scale can be adjusted.
[0006] Preferably, silicone balls are fixed at both the upper and lower ends of the cylindrical scale. The diameter of the cylindrical scale is 0.4 cm, and the length of the cylindrical scale is 20 cm. Through the function of the cylindrical scale, it is convenient to measure the depth of the funnel chest depression. With the function of the silicone balls, it can avoid discomfort to the patient caused by the end of the cylindrical scale.
[0007] Preferably, a pointer is also fixed on the upper end surface of the fixing frame, and the pointer is slidably connected to the cylindrical scale. Through the function of the pointer, it is convenient to read the measurement data.
[0008] Preferably, the rubber limit plate contacts with the cylindrical scale to achieve the positioning function, and pressing plates are symmetrically fixed on the left and right sides of the rubber limit plate. Through the action of the pressing plates, it is convenient to provide a force for the movement of the rubber limit plate. Combining with the limiting function between the rubber limit plate and the cylindrical scale, the fixing function of the position of the cylindrical scale can be achieved.
[0009] Preferably, a sliding rod is further fixed on one side of the rubber limit plate close to the fixing frame, and the sliding rod is slidably connected with the fixing frame. One end of a spring is fixed on the sliding rod, and the other end of the spring is fixed on the fixing frame. When the rubber limit plate moves, through the sliding guiding function between the sliding rod and the fixing frame, the stability of the movement of the rubber limit plate can be ensured. Combining with the action of the spring, when the rubber limit plate is not affected by an external force, a basic force can be provided for the automatic reset of the rubber limit plate.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: The funnel chest measuring scale of the present utility model adopts a rectangular scale and a cylindrical scale connected vertically, which can conveniently measure the relevant data of the funnel chest of a patient. Compared with the traditional tape measure measurement, the measurement data is more accurate, and the entire measuring scale has a simple structure and can be operated with one hand, which more meets the actual use requirements.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0016] Please refer to Figures 1 - 3The utility model provides a technical solution: a funnel chest measuring ruler, comprising a rectangular ruler 1 and a cylindrical ruler 2, the rectangular ruler 1 is vertically connected to the cylindrical ruler 2, the cylindrical ruler 2 is connected to a fixing frame 3, the fixing frame 3 is fixed on the rectangular ruler 1, and a rubber limiting plate 4 is provided on the front side of the fixing frame 3.
