Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, and particularly to a heart percussion measurement device. BACKGROUND

[0002] Heart percussion is a method of checking the size of the heart by the change of sound when the doctor taps the intercostal space of the patient's chest with his hand. The purpose is to determine the heart boundary, determine the size, shape of the heart and its position in the chest. The heart is a non-gas organ, and the part not covered by the lung is absolute dullness, and its boundary is absolute dullness boundary. The left and right boundaries of the heart are covered by the lung, and the percussion is relative dullness, and its boundary is relative dullness boundary. Percussion boundary refers to the relative dullness boundary of the heart percussion, because the relative dullness boundary reflects the actual size of the heart. When the heart is percussed, the left middle finger is parallel to the intercostal space, the right middle finger is vertically tapped on the left middle finger, and gradually moves inward, each time moving 0.5-1.0 cm. When the sound changes from clear to dull, it is the dullness boundary of the heart, and a measurement mark is made on the corresponding position on the surface of the chest. The shape and size of the heart are determined by the distribution area of several marks. The reference value of normal adult heart percussion measurement is: taking the front center line of the human body as the reference, the left boundary of the heart, ① the left second to third intercostal measurement point is 2-3 cm away from the front center line, ② the left third to fourth intercostal measurement point is 3.5-4.5 cm away from the front center line, ③ the left fourth to fifth intercostal measurement point is 5-6 cm away from the front center line, ④ the left fifth to sixth intercostal measurement point is 7-8 cm away from the front center line; the right boundary of the heart, ① the right second to third intercostal measurement point is 2-3 cm away from the front center line, ② the right third to fourth intercostal measurement point is 2-3 cm away from the front center line, ③ the right fourth to fifth intercostal measurement point is 3-4 cm away from the front center line.

[0003] Under normal circumstances, the distance from the left clavicular midline to the front center line plays a role in identifying the heart boundary measurement. The distance from the left clavicular midline to the front center line of a healthy patient is generally 8-10 cm. The distance between the left clavicular midline and the front center line needs to be judged according to the height, weight and age of each patient. For example, for adult population with larger body surface area, this distance may be longer; for underage people with smaller body weight, the distance between the left clavicular midline and the front center line may be shorter, especially for children, the distance between the two will be shorter.

[0004] In the prior art, the steps for medical staff to perform cardiac percussion measurement on patients are as follows: First, the doctor taps the surface of the chest outside the patient's heart with his hands, tapping out the left and right cardiac borders in turn and drawing measurement marks with a pen on the corresponding positions of the skin on the chest surface outside the heart. This operation requires the doctor to concentrate and operate carefully, not only to draw the measurement marks on the patient's skin surface, but also to ensure that all measurement marks are accurately positioned. Second, use a ruler to measure and register the distance between each measurement mark and the anterior midline of the human body in detail, draw a shape diagram of the measurement mark, and write down the measurement results. The disadvantages of this type of cardiac percussion are: the entire operation process is relatively messy and time-consuming, inefficient, difficult to operate independently, and often requires assistance from others. In addition, if the measurement mark is drawn in the wrong position, it will make the patient feel uncomfortable and difficult to operate. The measurement mark on the patient's skin needs to be cleaned afterwards, resulting in a poor experience, poor compliance, and low satisfaction for many patients. Summary of the Invention

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] As shown in Figures 1 to 9 The present application provides a heart percussion measurer. The rectangular pressing frame 19 can be made of flexible plastic material with a thickness of 3-4 mm, and the transparent plastic film 30 can be made of flexible plastic material with a thickness of 1-1.5 mm, which can be attached to the surface of the patient's chest. The horizontal ruler 15 and the vertical ruler 24 can be made of hard plastic material, which is convenient for sliding measurement. The use method is as follows: (see Figure 6 )(1) The doctor covers the rectangular pressing frame 19 on the transparent plastic film 30, and combines the hanging column 26 and the hanging hole 29 into the measurer body.(2) The patient lies flat and exposes the front chest, and the doctor places the measurer body on the patient's heart.(3) The doctor adjusts and positions the measurer body by moving it gently, aligns the first protruding indicator 20 with the front central line 6 and the protruding vertical line 27 to position the measurer body left and right, and places the horizontal ruler 15 between the left second to third intercostal space 10.(4) The horizontal connecting belt 17 is inserted into the patient's waist, and the vertical connecting belt 21 is inserted into the patient's back to keep the measurer body stable.(5) The specific method of percussion is from left to right, from bottom to top, and from outside to inside. The percussion is light tapping. When the left boundary is percussed, it starts from 2-3 cm outside the point with the strongest apical impulse, and the position is between the left fifth to sixth intercostal space 13. From outside to inside, when the percussion changes from clear tone to dull tone, a pen is used to make a measurement mark 32. In this way, each intercostal space on the left side is marked upwards until the left second to third intercostal space 10, and a measurement mark 32 is made respectively. When the right boundary is percussed, the liver upper boundary is first tapped, and from outside to inside, the dull tone boundary is tapped. From the right fourth to fifth intercostal space 7, each intercostal space on the right side is marked upwards until the right second to third intercostal space 9, and a measurement mark 32 is made respectively. When the sound changes from clear to dull during percussion, further repeated percussion is needed several times to avoid the obtained heart boundary being smaller than the actual range.(6) The distance from the front central line 6 to each measurement mark 32 is measured by the horizontal ruler 15, and each measurement mark 32 is drawn on the transparent plastic film 30 and a connected graph is drawn.(7) The second protruding indicator 23 on the left side of the vertical ruler 24 is aligned with the left midclavicular line 14 of the patient, the left side of the vertical ruler 24 is aligned with the left midclavicular line 14, and the distance 31 between the front central line and the left midclavicular line is measured by the horizontal ruler 15, which is recorded on the transparent plastic film 30 to ensure the accuracy of the measurement value and provide a basis for analyzing the patient's heart condition.(8) The patient's personal information card is filled in and put into the transparent plastic bag 28, and the measurement result is photographed and stored in the patient's medical record.(9) The heart percussion graph is analyzed (see Figure 8) The heart percussion measurement point distribution belongs to the normal state. (Ten), the heart percussion measurement point distribution belongs to the boot-shaped heart state, (see Figure 9 ) The left ventricle is enlarged, and the heart boundary is enlarged to the left and down, which is seen in hypertension, aortic valve disease.
