TECHNICAL FIELD

[0001] The present application relates to the technical field of medical supplies, in particular to a medical abdominal circumference measuring device. BACKGROUND

[0002] There is a small amount of liquid in the abdominal cavity of the human body to lubricate the organs, but when the amount of abdominal cavity fluid exceeds 200ml, it is abdominal effusion, which can make the abdominal circumference increase rapidly, cause the body organs to be pressed too much, and cause symptoms such as difficulty breathing, poor blood circulation, and abdominal pain. In order to observe the abdominal effusion, observe the treatment effect, and provide a basis for follow-up treatment, the abdominal circumference value of the patient needs to be measured and recorded continuously for many times.

[0003] The existing clinical practice is to measure with a flexible ruler, place the flexible ruler on the patient's waist, and read the data after wrapping around the navel once. In order to reduce errors, it is necessary to measure three times and take the average value. However, some patients with other diseases are inconvenient to move their bodies, and need multiple people to lift the patient and then place the flexible ruler on the patient's waist. In this process, the flexible ruler is easy to move, which can cause the measured data to deviate too much. In addition, due to the excessive abdominal effusion of the patient with abdominal effusion, the body weight increases significantly, making the process of lifting the patient time-consuming and laborious, increasing the workload of medical staff.

Detailed Implementation

[0034] A specific embodiment of the medical abdominal circumference measuring device of the present invention is as follows: Figs. 1-2 As shown, the medical abdominal circumference measuring device includes a housing 1 and a measuring tape measuring mechanism and a distance measuring circuit disposed within the housing 1. Specifically, the measuring tape measuring mechanism includes a rotating reset component and a flexible ruler 2 wound around the outside of the rotating reset component. In this embodiment, the rotating reset component is a spring 10. One end of the flexible ruler 2 is fixedly connected to one end of the spring 10. A measuring hole 3 is provided on the housing 1. The other end of the flexible ruler 2 passes through the measuring hole 3, and a stop strip 4 is installed at the end of the flexible ruler 2 that passes through the measuring hole, so that the end of the flexible ruler 2 is always limited to the outside of the housing 1. In use, the end of the flexible ruler 2 is pulled to make the flexible ruler 2 extend out of the housing. By reading the scale line on the flexible ruler 2 corresponding to the measuring hole 3, the length of the flexible ruler 2 extending out of the housing 1 can be obtained. After the measurement is completed, the flexible ruler 2 is released, so that the flexible ruler 2 automatically rewinds under the elastic force of the spring 10.

[0035] In the embodiment, the ratchet wheel is connected to the clockwork spring 10, the outer side of the ratchet wheel is provided with a pawl, the ratchet wheel and the pawl are in blocking cooperation in the direction of the tape measure recovery, so as to limit the tape measure after being pulled out, the housing is provided with a return button 11, the return button 11 is in transmission connection with the pawl, so as to drive the pawl to unlock the blocking of the ratchet wheel. When the tape measure is normally pulled out, the clamping grooves on the ratchet wheel can smoothly pass through the pawl in sequence, and when the clockwork spring is elastically contracted, the pawl can just clamp the clamping grooves on the ratchet wheel, so as to realize the clamping effect of the tape measure. When the measurement is completed, the return button 11 is pressed, so as to realize the automatic recovery of the tape measure. The design of the clockwork spring, the ratchet wheel and the pawl is shown in the patent document with the application number 2019219581917.

[0036] The housing 1 comprises a main body part and a handle part connected integrally, the tape measure mechanism is arranged in the main body part, the end of the main body part away from the handle part is provided with an arc-shaped abutting surface, the arc-shaped abutting surface is recessed inward, and the measuring hole 3 is arranged on the arc-shaped abutting surface.

[0037] The distance measuring circuit comprises a controller 9, a wireless distance measuring element 7, a display part 5 and a power supply 12, one side of the main body part is provided with a flat surface, the display part 5 is installed on the flat surface, the side of the main body part opposite to the flat surface is provided with a curved surface, the wireless distance measuring element 7 is installed at the position where the arc-shaped abutting surface and the curved surface intersect, the distance between the measuring hole 3 and the wireless distance measuring element 7 is 1-3 CM, and in the embodiment, the distance between the measuring hole 3 and the wireless distance measuring element 7 is 2 CM.

[0038] The flat surface of the shell 1 is also provided with a distance measuring switch 6, which is electrically connected with the display component 5. A positioning element 8 is arranged at the end of the flexible ruler 2 and is installed inside the stop strip 4. A controller 9 is also arranged in the shell 1 and is electrically connected with the wireless distance measuring element 7, the display component 5 and the distance measuring switch 6. In use, the wireless distance measuring element 7 is connected with the positioning element 8 through a Bluetooth signal. The working principle can be referred to the document with the title of “Bluetooth indoor distance measuring model research and precision analysis” (the authors are Zhang Yali, Wang Jian, Han Houzeng and Yang Deng) in the journal of “Surveying and Mapping Science”. The wireless distance measuring element 7 transmits the received Bluetooth signal to the controller 9. The controller 9 analyzes and processes the Bluetooth signal to obtain the distance between the wireless distance measuring element 7 and the positioning element 8 and displays the distance through the display component 5. In the embodiment, a power supply 12 is arranged in the shell 1 and a charging interface 13 is arranged on the shell 1. The power supply 12 is electrically connected with the charging interface 13 to ensure that the overall power of the device is sufficient. The straight-line distance between the wireless distance measuring element 7 and the positioning element is detected through the wireless distance measuring element 7. The distance between the measuring hole 3 and the positioning element 8 is obtained by reading the scale at the corresponding measuring hole 3 on the flexible ruler 2. Since there is a certain distance between the wireless distance measuring element 7 and the measuring hole 3, the distance from the wireless distance measuring element 7 to the measuring hole 3 will not be measured when the flexible ruler 2 is used for measurement. The starting scale of the flexible ruler 2 is equal to the distance between the measuring hole 3 and the wireless distance measuring element 7, that is, the starting scale of the flexible ruler 2 is 2 cm. The distance between the wireless distance measuring element 7 and the measuring hole 3 can be offset, which further ensures the measurement accuracy.
