Abstract

A peritoneal dialysis lean body mass detection device is characterized by comprising a grip strength handle, a parameter input device and a calculating display device. The grip strength handle is connected with a force measuring sensor. Grip strength obtained by the force measuring sensor and parameters input by the parameter input device are transmitted to the calculating display device. The calculating display device comprises a calculating device, and the calculating device calculates a lean body mass based on the grip strength obtained by the force measuring sensor and parameters such as gender and weight of a detected person according to the equations: male lean body mass=1*4.72+(centimeter numbers of height)*0.28+(kilogram numbers of weight)*0.27+(newton numbers of grip strength)*0.02-(number of dialysis months)*0.04-26.84, and female lean body mass=(centimeter numbers of height)*0.28+(kilogram numbers of weight)*0.27+(newton numbers of grip strength)*0.02-(number of dialysis months)*0.04-26.84. The calculating device displays an obtained lean body mass number on the display device.

Description

A kind of peritoneal dialysis lean body mass pick-up unit
Technical field:
The present invention relates to a kind of medical inspection device, particularly relate to a kind of peritoneal dialysis lean body mass pick-up unit.
Technical background:
Peritoneal dialysis (peritonealdialysis, PD) utilizes the peritonaeum of human body self as a kind of dialysis of dialysis membrane.Carried out the exchange of solute and moisture by the plasma fraction in the capillary of the dislysate and peritonaeum opposite side that pour into abdominal cavity, the metabolic product of retention in purged body and too much moisture, supplement the necessary material of body by dislysate simultaneously.By constantly upgrading peritoneal dialysis liquid, reaching kidney and substituting or the object of supportive treatment.When peritoneal dialysis treatment, by peritoneal dialysis catheters, peritoneal dialysis solution is filled with into abdominal cavity.In abdominal cavity, the side of peritonaeum is the blood containing refuse and excessive moisture in peritonaeum capillary, and opposite side is peritoneal dialysis solution, and the refuse in blood and unnecessary moisture enter in peritoneal dialysis liquid through peritonaeum.After a period of time, the peritoneal dialysis solution containing refuse and excessive moisture is released from abdominal cavity, then fill with new peritoneal dialysis solution of entering, so constantly circulate.Peritoneal dialysis is a kind of important way for the treatment of kidney failure, and peritoneal dialysis person refers to that needs carry out the crowd to maintain substance in vivo balance of peritoneal dialysis for a long time.
Muscle protein stores, and is to evaluate the good index of health, represents with lean body mass, and its international unit is kilogram, and gained lean body mass of the present invention is also using kilogram as unit, and the assessment of nutritional status for peritoneal dialysis person has important meaning.At present, for measuring the goldstandard of lean body mass: isotope water dilution method, or dual energy X-ray absorptionmetry, not enough below these two kinds of technical schemes: expensive, time and effort consuming, is not suitable for routine clinical use.Comparatively easy method has creatinine dynamic method, and the lean body mass English that this method measures is abbreviated as LBM-CK (kg), but, because the creatinine fluctuation of peritoneal dialysis person is comparatively large, so the method is not high for peritoneal dialysis person's accuracy; Also have anthropometric method to estimate lean body mass, its English is abbreviated as LBM-A (kg), due to peritoneal dialysis person, oedema may occur or other factors cause it comparatively to become thin, so the method is also inaccurate.
Summary of the invention:
Goal of the invention of the present invention is to provide one can cheap and simple peritoneal dialysis person people lean body mass pick-up unit, in order to complete object of the present invention, the present invention by the following technical solutions:
