Problems solved by technology

The usual practice is: the doctor applies a certain force to the skin of the diseased tissue with his own fingers to judge, and each doctor's pressure and judgment standards cannot be unified
Even if the same doctor has different pressure levels and judgment standards in different time periods, there will be differences

Embodiment 1

[0037] Example 1 A device for measuring the stage of lymphedema by indentation depth

[0038] refer to figure 1 , the present invention is a device that indirectly reflects the composition of lymphedema tissue through the indentation depth on the body surface, and is suitable for judging the stage of lymphedema patients and the progress of swelling. The device consists of a shell 1, a shell plate 2, a time screen 3, a parameter setting key 4, an item turning key 5, a column shell 6, a negative pressure key 7, a depth screen 8, a confirmation key 9, a start key 10, and a chassis assembly 11. The measuring assembly 12 is formed by two housing holes 13 . refer to figure 2 , the whole structure is composed of upper, middle and lower parts, wherein the chassis assembly 11 is the middle part, the measurement assembly 12 is the lower part, and the rest is the upper part. The composition and relative relationship of each part will be described later.

Embodiment 2

[0042] Example 2 using the invention (patient's arm as an example)

[0043] Step 1 Patient Preparation: Refer to Figure 19 , ask the patient to sit on the chair, place the forearm on the table in a naturally relaxed state, and disinfect the skin area to be measured.

[0044] The second step machine setting, refer to image 3 and Figure 16 , press the negative pressure key 7 to check whether the vacuum pump 26 is working, press the parameter setting key 4, the flip key 5 and the confirmation key 9 to set two parameters: 1. Pressing pressure setting: the pressing force of the pressing ball 35 is controlled by the motor 33 provides that the power output by the motor 33 is adjusted by setting the threshold current intensity in the motor 33 circuit. The force that causes the pressure ball 35 to press down before each measurement is all the same. 2. Delay time setting: After the pressure ball 35 presses the skin and returns to the initial position (the telescopic column 38 exp...

Abstract

The invention provides a device for measuring a lymphedema period by indentation depth. The device is composed of a shell, a shell plate, a time screen, a parameter setting key, an item turning key, a cylindrical shell, a negative pressure key, a depth screen, an enter key, a start key, a chassis assembly, a measuring assembly and two shell holes. A suction nozzle negative pressure fixing method is adopted, and contact with the skin is safer and more stable; and an electrically-controlled pressing telescopic column is adopted, and current threshold value control is adopted, so that the repeatability and the pressing precision are higher; besides, the design of the upper limit and the time screen enables the delay measurement to be more scientific, the stop rebound to the upper limit in place is used as a timing starting point, the timeliness of the measurement and the measurement time after pressing can be set, the rebound interference of the recess is effectively avoided, and the setting of a unified measurement standard is facilitated. The receiver and the emission lamp are the basis of infrared distance measurement, wherein the infrared distance measurement is accurate, practical and rapid. The device is reasonable in design and suitable for judging the stage and swelling progress of the lymphedema patient.

Description

technical field [0001] The invention belongs to medical instruments, and relates to a device for measuring lymphedema stage by indentation depth, which is a medical diagnosis device for postoperative lymphedema of a patient, and is a device for measuring and evaluating swelling degree and stage. Background technique [0002] Infrared rangefinder: The principle of infrared distance measurement technology is to use the principle of non-diffusion when infrared rays propagate. The propagation of infrared rays takes time. When the infrared rays are emitted from the rangefinder and hit the reflector, they are reflected back and received by the rangefinder. The distance can be calculated according to the time from sending out to being received by infrared rays and the propagation speed of infrared rays. The advantages of infrared ranging are cheap, easy to manufacture, safe and high precision. As a precision measurement tool, infrared range finder has been widely used in various ...
