Abstract

The utility model relates to a special sickbed for dialysis, which can monitor the body weight in real time. A weighing transducer is installed underneath the four feet of the bed and connected to a display screen which is used to demonstrate the weighing result through a cable. An interface of the weighing transducer is cylindrical and is plugged between the feet of the bed and the floor, and the lower end face of the weighing transducer is a force-measuring end. The special dialysis sickbed can monitor the weight, as well as the liquid load changes caused by food, water, blood transfusion and infusion accurately and timely in the circumstances that the patient staying in bed. The ultra filtration volume is adjusted in the process of dialysis for further fulfilling the dialysis and avoiding the complication caused by hypotension because of excessive ultra filtration, and the heart failure by liquid overload during the dialysis due to the lack of ultra filtration.

Description

A kind of special-purpose sick bed of dialysis that can monitor body weight in real time

One, technical field:

The utility model relates to medical sick bed, specifically relate to a kind of special-purpose sick bed of dialysis that can monitor body weight in real time.

Two, background technology:

Hemodialysis is one of effective ways of treatment renal failure in whole latter stage, in recent years, the blood purification technology makes much progress, dialysis machine becomes better and approaching perfection day by day along with the progress of microelectric technique and material science, and intelligent hemo system and biocompatible dialysis film and dialysis solution are in extensive use.Whole this index of urea clearance rate KT/V of medically normal employing reflects the single dialysis-effect, adopt this index to adjust the dialysis scheme, KT/V=-ln (R-0.008T)+(4-3.5R) uf/W, ln natural logrithm in the formula, the T dialysis time, 0.008T the carbamide growing amount is to the influence of KT/V in the dialysis procedure, the uf ultrafiltration volume, W dialysis back body weight, because used bed, patient can not survey body weight when lying on a bed dialysis, W is dialysis back body weight, so this index is actually the index that the adequacy of dialysing after the dialysis is estimated, dialysis Shi doctor adjusts the dialysis scheme by patient's body weight of weighing of going to bed before the dialysis, determines the time of dialysis.But, in the most patient dialysis procedure, all feeds in various degree, water inlet or since change of illness state need transfuse blood, infuse, body weight is changed, under these situations, medical personnel are rough estimate patient's intake and feed liquor amount often, and this part estimator is added in the ultrafiltration volume, but, this has deviation because of estimator and actual intake and feed liquor amount again, cause excessive ultrafiltration or ultrafiltration deficiency, ultrafiltration excessively can cause hypotension and produce serious complication, and the ultrafiltration deficiency can cause dialysis interval liquid load overweight and bring out heart failure.

Three, summary of the invention:

The purpose of this utility model provides a kind of special-purpose sick bed of dialysis that can monitor body weight in real time, and this special-purpose sick bed of dialysis that can monitor body weight in real time is used to solve the problem that used bed can not be monitored body weight in real time to hemodialysis patient.

The purpose of this utility model is to be achieved by following technical proposals: this special-purpose sick bed of dialysis that can monitor body weight in real time is below four footposts of bed LOAD CELLS to be installed, LOAD CELLS connects display screen by cable, and display screen is used to show weighing results; The interface of LOAD CELLS is columniform, is plugged between footpost below and the ground, and the lower surface of LOAD CELLS is the dynamometry end.

The columniform interface of LOAD CELLS in the such scheme has screw thread outward, is threaded between the interface of LOAD CELLS and the footpost.

The utlity model has following advantage and good effect:

This special-purpose sick bed of dialysis of body weight of can monitoring in real time is during patient treatment, under the situation of not leaving bed, can monitor body weight, even patient has feed in various degree in therapeutic process, water inlet, blood transfusion, transfusion, also can monitor out in time, for treatment provides data timely and effectively, particularly can be in dialysis procedure, accurately and timely monitor because of feed, water inlet, blood transfusion, the liquid load of infusing and producing changes, in dialysis procedure, ultrafiltration volume is adjusted, make dialysis more abundant, the hypotension of having avoided ultrafiltration excessively to cause causes serious complication and ultrafiltration deficiency to cause the overweight and heart failure that brings out of dialysis interval liquid load.

Four, description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of LOAD CELLS in this utility model;

Fig. 3 is the structural representation of the LOAD CELLS of another kind of embodiment in this utility model;

Fig. 4 is this utility model fundamental diagram.

Among the figure: 1 footpost, 2 LOAD CELLSs, 3 display screens, 4 interfaces, 5 dynamometry ends

Five, the specific embodiment:

As shown in Figure 1, this special-purpose sick bed of dialysis that can monitor body weight in real time is that LOAD CELLS 2 is installed below four footposts 1 of bed, the outfan of four LOAD CELLSs 2 is inserted on the plug connector of display screen 3 by cable, weighing results is shown on the display screen 3, display screen 3 is a liquid crystal display screen, on and off switch, zero setting button, range button are arranged on it, can be as required when measuring will the state of weighing at that time be changed to zeroly, make and in measuring process, can remove " preceding heavy " easily; As shown in Figure 2, the interface 4 of LOAD CELLS 2 is columniform, be plugged on footpost 1, the lower surface of LOAD CELLS 2 is a dynamometry end 5, after the installation, LOAD CELLS 2 is between footpost 1 and ground, and the dynamometry end 5 of LOAD CELLS 2 lower ends contacts with ground, and the cable connector on the cable connector of LOAD CELLS 2 and the display screen 3 is pegged graft.

Fig. 3 is the structural representation of the LOAD CELLS of another kind of embodiment in this utility model, as shown in the figure, outside the columniform interface 4 of this LOAD CELLS screw thread is arranged, and this LOAD CELLS 2 is threaded with footpost 1.Other structure is identical with the structure of LOAD CELLS shown in Figure 2.

Fig. 4 is this utility model fundamental diagram, as shown in the figure, act on the gravity of the dynamometry end 5 of LOAD CELLS, the Wheatstone bridge that foil gauge on the elastomer of LOAD CELLS 2 is formed has produced voltage sensing signal, signal magnitude is directly proportional with weight, through the amplification filtering circuit voltage signal is amplified, and transfers aanalogvoltage to the ISN numeral through the A/D change-over circuit again, digital signal by the central processor CPU calculation process after, show with digital form by display screen 3.

This utility model is owing to be installed in the electronics automatic weighing system between footpost 1 below and the ground, can the liquid load of dialysis patient be changed, it is body weight change, carry out real-time dynamic monitoring, targetedly therapeutic scheme is adjusted, determined the time of dialysis, can whether normally monitor the dialysis machine ultrafiltration volume again simultaneously, whole dialysis treatment is carried out under can monitoring, improved the adequacy and the curative effect of dialysis.
