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

Abstract

The invention provides a device for indirectly measuring lymphedema by the compression degree of an air bag. The device is composed of a wearing piece, an operating platform and a lifting supporting piece, wherein the wearing piece, the operating platform and the lifting supporting piece are sequentially stacked and connected from top to bottom. The swelling degree of the forearm of a patient with lymphedema is quantitatively measured according to the compression degree of the air bag in the fixed space. Compared with existing equipment, the device has the advantages that (1) hospital infection control is better, and completeness and dryness of the skin can be guaranteed through no water body contact; (2) the measurement is more convenient and quicker: the self-adaptive sealing design is convenient for blocking and clamping; (3) quantitative measurement is facilitated through airflow measurement and calculation; and (4) the comfort of the patient is good: the design of the lifting desktop is convenient to adapt to the heights of different patients, and the somatosensory of the tested patient is better.

Description

technical field [0001] The invention belongs to medical equipment, and relates to a medical diagnosis device for postoperative lymphedema of a patient, in particular to a device for indirectly measuring lymphedema by the compression degree of an air bag, which is a device for measuring the degree of limb lymphedema. Background technique [0002] A hydraulic jack refers to a light and small lifting device that uses a rigid lifting piece as a working device to lift heavy objects in a small stroke of the top bracket or bottom claw. The most basic principle on which hydraulic transmission is based is Pascal's law, that is to say, the pressure of the liquid is the same everywhere. Thus, in a balanced system, the smaller piston exerts less pressure and the larger piston exerts more pressure, keeping the fluid still. Therefore, through the transmission of liquid, different pressures on different ends can be obtained, and a purpose of transformation can be achieved. The hydraulic ...
