Description
Technical field
The utility model belongs to medical instruments field, particularly a kind of lymphedema limbs volume measurement device.
Background technology
Lymphedema refers to soft tissue liquid that body some position lymph liquid backflow obstructions cause after body surface repeated infection
Subcutaneous fibrotic connective tissue proliferation, adiposclerosis.
It is at present domestic still few with regard to the research of extremity lymphedema measuring method, mainly have upper-arm circumference mensuration, water displacement method,
Perometer (Perometer) mensuration and bio-electrical impedance spectral measurement method (Bioimpedance
Spectroscopy, BIS) 4 kinds of measuring methods.
Its MAC mensuration measures the upper-arm circumference of limbs using survey tool, and this kind of measuring method is simple, quick, expend
It is low, but accuracy is not high, and error is larger, the ununified regulation of the position of measurement point and quantity, and cannot measure hand
Volume Changes.
Water displacement method is the goldstandard for measuring lymphedema, and water displacement method has two ways, and a kind of is in particular size
A certain amount of water is put in steel drum, then limbs certain length in bucket is put into into, limbs are extrapolated according to the height change of the water surface
Volume.Another kind piles in a reservoir water, and limbs are put into into the volume of the water that direct measurement is overflowed after container, or to this part
Water calculates volume after weighing.But this measuring method is excessively cumbersome, and equipment is not portable, not being suitable for upper limbs has the trouble of wound
Person, also easily causes cross-infection.In addition, water displacement method needs measurement of bending over, the probability of patient's tumble is increased.And water is replaced
There is the difference in obvious operator and between operator in method and upper-arm circumference mensuration.
Perometer (Perometer) mensuration is the volume that limbs are recognized using far-infrared technique, removable by one
Dynamic framework is slow, constant level's movement, and through the upper limbs of patient's extension, lower portion surrounding has parallel far infrared transmitting
Device, can obtain the volume of limbs by analyzing the shade position blocked by limbs.This kind of method measurement volume is quick, accurate
Rate is high, operating error is little, and Reliabity is also good than other instruments, but somewhat expensive and equipment volume is big.By measuring limb
Body volume and upper-arm circumference change to assess lymphedema, and accuracy rate is high, but for the lymphedema of obvious tumefaction not yet occurs in early stage
Often can not monitor out, it is impossible to which it is due to the change of muscle or fat or due to drenching that the volume or upper-arm circumference that differentiation is measured changes
The reason that bar liquid is assembled in tissue space.
Bio-electrical impedance spectral measurement method is the nothing that Human Physiology information is extracted using the electrology characteristic of biological tissue
Wound monitoring technology, it is to be input into faint detection electric current to human body using the electrode for being placed in body surface, then measures suitable position
Voltage change, so as to obtain the electrical impedance situation of change of linked groups or organ, to obtain physiology and pathological information.The method can
It is accurately to detect the sole instrument of this change to accurately distinguish the change of intracellular fluid and outer liquid, therefore can be used for clinical symptoms and go out
The early detection of lymphedema before now, BIS equipment is also little than Perometer and expense is low, and patient compliance is convenient, whole process
Quick painless, Noninvasive, and limbs need not be moved or uncomfortable posture is kept, the comfortable of patient is increased, subtract
The probability fallen is lacked.BIS by Food and Drug Administration by using, but have pacemaker or metal implants
Patient can not use.In addition, for chronic irreversibility lymphedema patient, because its tissue has occurred fibrillatable, also not
It is adapted to be detected using BIS.
From the foregoing, it will be observed that there is no one kind easy to operate in prior art, and can accurately measure all lymphedema patients
The device of limbs volume.
