Description

The low-cost residual urine liquid drainage measuring system of safety and sanitation

Technical field

The present invention relates to a kind of low-cost residual urine liquid drainage measuring system of safety and sanitation.

Background technology

Male more than 60 years old, the sickness rate of prostatic hyperplasia wherein, has the part patient that tangible urinary dysfunction is arranged up to more than 30%, comprises that urine retention, residual urine volume are many etc., and comparatively under the serious situation, the remnants amount of urinating reaches 400ml.In addition, the disturbance of consciousness of urinating can appear in the patient of some nerve injury, and residual urine volume is very big.As everyone knows, a large amount of urine amount remnants can seriously injure renal function, and therefore, the residual urine volume of understanding the dysuria patient just seems extremely important in clinical diagnosis.

The method of traditional measurement residual urine volume mainly is divided into two kinds: bladder is inserted with a drainage tube per urethra in (1); Measure through instruments such as measuring cup or graduated cylinders behind the drainage of urine; The drainage speed of general drainage pipe is slow; And going up urinary tract during drain has endlessly that urine flows into bladder, therefore, drainage time is long, waste time and accuracy relatively poor.(2) adopt three-dimensional type-B ultrasonic to measure, measure by internal calculation and accomplish, the method not only expense is high, and precision is low.

Also have some clinical workers to invent a kind of negative pressure pump that utilizes and carry out drain, automatic control system is controlled, the residual urine liquid drainage measuring system that liquid flow sensor and LOAD CELLS are measured.Like ZL200910191540; Quick urine drainage and determination system; Comprise negative pressure pump, drainage tube, metering device, liquid flow sensor and PLC automatic control system; Liquid flow sensor is arranged in the medium inlet of negative pressure pump, the signal of liquid flow sensor input PLC automatic control system, and the signal output part of PLC automatic control system is electrically connected with the control circuit of negative pressure pump; Metering device comprises pallet and LOAD CELLS, and pallet is fixedly set on the LOAD CELLS, the gravitational cue input PLC automatic control system of LOAD CELLS; It also comprises electrodynamic valve, and the medium inlet links to each other through electrodynamic valve with drainage tube, and the signal output part of PLC automatic control system links to each other with the command reception end of electrodynamic valve.This scheme is carried out negative pressure drainage (big or small with the flow of regulating urine in the drain pipeline by PLC automatic controlling system electrodynamic valve) through negative pressure pump to urine; Measure the amount of urine of drain gained again through metering device, advantage such as have that drainage speed is fast, accuracy of measurement is high and easy to operate.Yet there is following shortcoming in this scheme: (1) liquid flow sensor is placed in the drain loop, if disposable use, cost is too high, and patient can't accept; If want to recycle repeatedly, the very difficulty of cleaning, sterilize.(2) weighing device uses the pellet type LOAD CELLS, and in the use, operator do not note damaging pick off slightly, uses very inconvenient.(3) electrodynamic valve is placed between the medium inlet and drainage tube of negative pressure pump, and electrodynamic valve is as if disposable use, and cost is high, and patient can't accept; If reuse, must clean at every turn and sterilize, cleaning and sterilization not only bother but also are difficult to reach sanitary standard.

Summary of the invention

The objective of the invention is to solve the deficiency of prior art, a kind of low-cost residual urine liquid drainage measuring system of novel safety and sanitation is provided.

The objective of the invention is to realize: the low-cost residual urine liquid drainage measuring system of safety and sanitation through following technical scheme; It comprises drainage tube, peristaltic pump, urine drainage bag, the hook of weighing, LOAD CELLS, micro-control unit and display; Drainage tube links to each other with the inlet of peristaltic pump; The wriggling delivery side of pump links to each other with the inlet of urine drainage bag through flexible catheter, and urine drainage bag is articulated on the hook of weighing, and the hook of weighing is connected with LOAD CELLS; The gravitational cue outfan of LOAD CELLS is connected with the signal input part of micro-control unit, and the signal output part of micro-control unit is connected with display with peristaltic pump respectively.

Peristaltic pump of the present invention comprises that connecting wriggling of its inlet and outlet presses pipe.

Of the present invention wriggling presses pipe to press pipe for detachable disposable wriggling.

The invention has the beneficial effects as follows:

(1) employed wriggling presses pipe for disposable on the peristaltic pump, uses dismounting later, changes and get final product, solved the problem that the conventional negative press pump cleans and sterilization is difficult, and safety and sanitation and cost are low;

(2) micro-control unit calculates the flow rate of urine through the variable quantity of urine weight in the measured urine drainage bag, ban the expensive liquid flow sensor of tradition, has reduced system cost and has solved that liquid flow sensor cleans and the problem of sterilization difficulty;

(3) disposable urine drainage bag is hung on the coupling type LOAD CELLS measure, easy to use and not fragile, cost is also low than the pellet type LOAD CELLS;

(4) the measurement result accuracy of this measuring system is high, and safety is good, and is simple to operate; Measuring speed is fast, behind the complete one-shot measurement, need not to clean or any system unit of sterilizing; Only need to change drainage tube, wriggle and press pipe and urine drainage bag, three costs are added up and are no more than 10 yuan.
