[0002] Since critically ill patients often have hemodynamic instability and poor oxygenation, it is difficult to go out for lung CT examination. In recent years, lung ultrasound, as a bedside, rapid, and dynamic examination method, has a high diagnostic and treatment guidance value in the evaluation of lung diseases such as pulmonary interstitial edema, pneumonia, pulmonary consolidation, pleural effusion, pneumothorax, and subpleural masses. The BLUE-plus examination method is a modified lung ultrasound examination method. It is an important and reliable means for the diagnosis and clinical monitoring of lung diseases in critically ill patients. This examination method helps medical staff to quickly differentiate and diagnose a variety of lung diseases through a series of standardized steps and terminology. Usually, the operator's palm is compared with the patient's palm, and then the operator's palm is used to mark the various test points on the chest, determine the location of each test point, and perform the test. However, the size of the operator's palm and the patient's palm is different, and there will always be deviations when using the operator's palm to determine the location of the test point. If the patient's palm is printed on an intermediate carrier (such as white paper) and marked before being placed on the patient's chest, the intermediate carrier is usually disposable and has poor versatility. At the same time, this improved lung ultrasound examination method usually has 10 points to be evaluated, which is particularly complicated for a beginner in critical ultrasound.

In the adjustment state, the guide locking member 400 and the positioning ruler 300 can also rotate along the central axis of the guide locking member 400.

[0036] The utility model provides a detection point positioning auxiliary device for lung B-ultrasound detection. The positioning ruler 300 can be used to realize the positioning auxiliary of the detection point, and the positioning ruler 300 can be telescopically adjusted in length to adapt to the palm sizes of different people. When the guide locking member 400 is in the adjustment state, the positioning ruler 300 can slide along the corresponding strip groove 110, and can also rotate along the guide locking member 400, so as to realize multi-dimensional position adjustment to adapt to different patient palms. After the adjustment, the guide locking member 400 can be movably adjusted so that the guide locking member 400 is switched to the locking state, and the position of the positioning ruler 300 is locked, so that it is convenient to place the device on the patient's chest to perform positioning mark auxiliary of the detection point later; it can adapt to the palms of different patients to perform detection point positioning auxiliary, reduce position deviation, and has good versatility.

[0037] Reference Figure 4 In some embodiments of the utility model, the positioning ruler 300 is provided with a first threaded hole 301 corresponding to the strip groove 110, and the guide locking member 400 is provided with a stud 410 threadedly connected to the first threaded hole 301, thereby realizing the movable connection between the guide locking member 400 and the positioning ruler 300, so that the guide locking member 400 can be rotated forward and backward to realize the state switching.

[0038] Reference Figures 2 to 4 In some embodiments of the utility model, a guide column 420 adapted to the strip groove 110 is provided at the front end of the stud 410, that is, the diameter of the guide column 420 is adapted to the width of the strip groove 110, so that the guide column 420 can move along the strip groove 110 in the strip groove 110 and can also rotate around its own axis to achieve multi-dimensional adjustment.

[0039] Reference Figures 2 to 4In a further embodiment of the present invention, a close-fitting post 430 located at the front side of the strip groove 110 is provided at the front end of the guide post 420, and the close-fitting post 430 has a diameter greater than the width of the strip groove 110. When the guide locking member 400 is in the adjustment state, the close-fitting post 430 is separated from the front side of the positioning ruler 300, so that the guide locking member 400 can rotate and move, and the angle and position of the positioning ruler 300 can be adjusted; when the guide locking member 400 is in the locked state, the close-fitting post 430 is in close contact with the front side of the positioning ruler 300, and the friction between the close-fitting post 430 and the positioning ruler 300 is used to fix the position of the positioning ruler 300 and the guide locking member 400, and the guide locking member 400 is movable and adjusted to realize the switching between the adjustment state and the locking state, which is convenient to operate, and only needs to screw the guide locking member 400.
