Embodiment 1
[0054] Example 1 A device for indirectly measuring lymphedema by the degree of compression of the airbag
[0055] refer to figure 1 , the present invention provides a device for indirectly measuring lymphedema by the compression degree of the air bag. This part consists of a patient wearer 28 , an operating platform 29 and a raised support 30 . The wearing part 28 , the operating platform 29 and the raising support part 30 are stacked and connected sequentially from top to bottom. The composition and connection of each component are described in detail later.
[0056] refer to figure 2 , wherein the wearer 28 is the main part of the patient's arm test and is the sampling (tested) part of the entire device. The device consists of a cartridge assembly 31 and two adaptive closure assemblies 32 . The composition and connection of each component will be described later.
[0057] refer to image 3 with Figure 4 , wherein the barrel assembly 31 is a container into which the...
Embodiment 2
[0065] Embodiment 2 uses the present invention (measure patient's right arm as example)
[0066] The first step of machine preparation: refer to Figure 26 , when the rotation of the L-shaped ball valve 48 is , the L-type ball valve 48 will be connected with the upper port (valve pipe 40) and the left port (suction pipe 51) and cut off the right port pipeline (inflatable pipe 45), and now the passage of the suction pump 63 is unimpeded. refer to Figure 22 , press the suction key 73, the suction pump 63 starts to work, the gas remaining in the annular airbag 38 will be discharged after reaching the flowmeter 57 through the suction pipe 51, and the suction pump 63 will suck all the gas in the annular airbag 38 clean , as the inhalation continues, the negative pressure in the annular airbag 38 is formed, and when the negative pressure reaches the threshold set by the suction pressure sensor 50, the suction pressure sensor 50 will transmit a signal power-off signal to the suct...
Embodiment 3
[0073] Embodiment 3 compares with conventional water volume displacement method
[0074] The advantages and disadvantages of the present invention and conventional water volume displacement method in table 1
[0075] water displacement method This device conversion medium water Air Nosocomial control water can cause skin infections anhydrous, dry applicability Prepare the measuring cylinder All-in-one comfort The water temperature is low, the patient bends over Sitting position, height adjustable Measurement positioning No standard for immersion depth U bar fixed Accurate reading Scale reading error is large digital security function none The degree of inflation of the airbag is controllable repeatability poor Perfect unity no uniform standard One machine unified Convenience Canister change and water change for each patient Convenience
