Problems solved by technology

BIS has been approved for use by the FDA, but not for patients with pacemakers or metal implants
In addition, BIS is not suitable for patients with chronic irreversible lymphedema because of the fibrosis of their tissues
[0008] It can be seen from the above that there is no device in the prior art that is easy to operate and can accurately measure the limb volume of all lymphedema patients

Abstract

The invention discloses a lymphedema limb volume measuring device which comprises a measuring room, a negative pressure sucking pump, a measuring cylinder, an elastic sealing sleeve, a connecting pipe, an air communication valve and a connecting pipe valve. The measuring room is of a hollow structure, one end of the measuring room is provided with a hole into which a limb is allowed to stretch, the hole is sleeved with the elastic sealing sleeve, the front end of the elastic sealing sleeve stretches into the measuring room, the hole and the elastic sealing sleeve are mutually sealed, two through holes are formed in the top of the measuring room, one through hole is connected with the negative pressure sucking pump, the other through hole is provided with the air communication valve, a through hole is formed in the bottom of the measuring room and connected with the measuring cylinder through a connecting pipe, and the connecting pipe is provided with the connecting pipe valve. The lymphedema limb volume measuring device is simple in structure and convenient to operate.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a lymphedema limb volume measuring device. Background technique [0002] Lymphedema refers to hyperplasia of subcutaneous fibrous connective tissue and fat sclerosis after repeated infection of soft tissue fluid on the body surface caused by blocked lymphatic reflux in certain parts of the body. [0003] At present, there are few domestic studies on the measurement methods of limb lymphedema. There are mainly four measurement methods: arm circumference measurement method, water replacement method, blood loss meter (Perometer) measurement method and bioimpedance spectroscopy (BIS) measurement method. [0004] Among them, the arm circumference measurement method uses measuring tools to measure the arm circumference of the limbs. This measurement method is simple, fast, and low in cost, but the accuracy is not high and the error is large. The volume change of the part. [0005] Th...
