Description
Technical Field
The present invention relates to a hemodialysis control apparatus and method, and more particularly to a monitoring system for monitoring the use status of hemodialysis solution.
Background
Hemodialysis (HD), also called hemodialysis for short, is one of the kidney replacement therapy methods for patients with acute and chronic renal failure. Popular expression is also called kidney washing, which is one of the blood purification techniques. It utilizes the principle of semipermeable membrane, and can remove various harmful and redundant metabolic wastes and excessive electrolytes from human body by means of diffusion so as to attain the goal of purifying blood and correcting water electrolyte and acid-base balance. Hemodialysis is one of the safer, easy-to-use and widely-applied blood purification methods.
Hemodialysis's equipment includes hemodialysis machine, water treatment and cerini dialyser cerini, and they constitute hemodialysis system jointly. The hemodialysis liquid generally comprises a liquid A and a liquid B, which are respectively an acid liquid and an alkali liquid. The dialysate is pre-loaded into the dialysate barrel, and when in use, the pipette connected to the dialysis machine is inserted into the dialysate barrel, and the dialysate is pumped out into the dialysis machine.
Generally, a barrel of dialysate cannot be used up in dialysis of one patient, and the unused dialysate can be used up by a second patient. However, in some cases, the volume of dialysate in a barrel is not sufficient for two patients. Therefore, the nursing staff is required to pay attention to the dosage of the dialysate in the dialysate barrel, and the dialysate barrel filled with sufficient dialysate is replaced in time when the dialysate is used up, so that the phenomenon that the air is sucked into a dialysis pipeline when the dialysis machine runs a liquid suction process after the dialysate is used up is avoided. Although the existing hemodialysis machine equipment is provided with an air monitoring system, the hemodialysis machine equipment can not give an alarm to prompt the replacement of dialysate until the dialysate is vacuumed and bubbled after being used. The fact that air bubbles have been sucked in results in the interruption of the treatment by stopping the operation of the apparatus when the dialysis fluid is replaced. And the long-time alarm of the equipment can cause panic of the patient.

As shown in fig. 1 to 4, the loading tray 1 is provided on the upper surface of the monitoring device, and the weight sensor is installed in the monitoring device, and the weight sensor is located below the loading tray 1 and contacts with the loading tray 1. The central processing unit is installed in the monitoring equipment.
The alarm device is selected from a light alarm device, a sound alarm device or a combination of the light alarm device and the sound alarm device. The monitoring device of fig. 1 to 4, the alarm means comprise light alarm means 5 and sound alarm means 6. The light alarm device and the sound alarm device can be arranged at any position of the monitoring equipment, which can enable the monitoring equipment to play the role of alarm reminding. In a preferred design scheme, the upper surface of the carrying tray 1 is provided with a groove 11, and the light alarm device is embedded in the groove of the carrying tray. In order to ensure that objects (such as a dialysate barrel) can be stably placed on the carrying tray, the light alarm device arranged in the carrying tray is not higher than the supporting surface of the carrying tray. The dialysate barrel that uses now is transparent, puts the back on carrying the thing tray when the dialysate barrel, and the light alarm device who inlays on carrying the thing tray just lies in the below of dialysate barrel. When light sends the bright light, the light can shine the dislysate in the bucket through the dislysate bucket, lets the dislysate also refract the colour of light to let the nursing staff notice this alarm information more obviously.
The light alarm device can be an LED lamp strip or any other device capable of emitting light. The sound alarm device may be a buzzer or any other device capable of emitting sound. In a preferred design, the light color of the light alarm device may include a plurality of colors, for example, three-segment display of green, yellow and red, which respectively correspond to different alarm parameters. The sound alarm can also be divided into multi-section rhythm alarm modes, such as alarm sound relaxation, alarm sound urge or alarm sound sharpness, and the like, so as to respectively correspond to different weight parameters.
Various control thresholds or parameters can be fixedly set in a central processing unit of the monitoring equipment. Or the monitoring equipment can also comprise a parameter input device, later-stage parameter setting is carried out according to the actually used dialysate barreling quantity specification, and real-time weight can also be displayed on line. The parameter input device shown in fig. 1 and 5 is a liquid crystal touch screen 7, the touch screen 7 is connected with a central processing unit, and parameter settings include but are not limited to: starting weight of the dialysate barrel, starting sound alarm of sectional type alarm (for example, according to different alarm duration, divided into primary alarm, secondary alarm and alarm needing emergency treatment), network alarm starting mode, light alarm light color mode (for example, single color, gradient color or multiple colors), and the like.
The hemodialysis liquid generally comprises a liquid A and a liquid B, wherein the liquid A is used for adjusting the ion concentration of human body fluid and mainly comprises sodium, potassium, calcium, magnesium, glucose and other components, and the liquid B is used as a buffering agent for keeping the acid-base balance of the body fluid and mainly comprises sodium bicarbonate and other components. The solution A and the solution B need to be respectively packaged in different dialysate barrels, and if the solution A and the solution B are not separately packaged, the solution A and the solution B can generate chemical action to generate precipitation. Thus, in the embodiment shown in fig. 1 and 4, the monitoring device comprises two sets of carrier trays 11, a first weight sensor 21, a second weight sensor 22 and alarm means (a first light alarm means 51, a second light alarm means 52, a first sound alarm means 61 and a second sound alarm means 62), both sets of weight sensors and alarm means being connected to the central processor 3. The parameter input device can be selected from one group or two groups, wherein the two groups comprise two sets of parameter systems respectively aiming at the liquid A and the liquid B, and the two sets of parameter systems can be mutually switched when setting parameters. In another implementation, the monitoring device includes only one set of carrier trays, a weight sensor, an alarm device, and a set of parameter systems. When hemodialysis is carried out, two monitoring devices are adopted to respectively place the A liquid hemodialysis liquid barrel and the B liquid hemodialysis liquid barrel, and parameters are respectively set.
The monitoring device as shown in fig. 3 may further comprise an infusion control device 8, one end of which is connected to the central processor and the other end of which is connected to a component of the infusion pump 9 controlling the operation of the infusion pump. One end of the pipette 91 is inserted into the dialysate barrel and the dialysate is pumped out of the dialysate barrel by the infusion pump into the dialysis machine. The infusion pump can be a peristaltic pump or the like. When the monitoring equipment sends out light alarm and sound alarm information, the nursing staff still does not change the dialysate barrel on the monitoring equipment, the central processing unit can send out an instruction to the infusion control device, and the infusion control device is started. The infusion control device can reduce the liquid pumping speed of the infusion pump after being started so as to reduce the liquid reduction speed in the dialysate barrel, and more time is left for a nursing staff to replace a new dialysate barrel before the dialysate is used up. Or the infusion control device directly stops the operation of the infusion pump after being started, so as to avoid sucking a large amount of air and wait for the replacement of a new dialysate barrel by a nursing staff.
The monitoring device may further comprise a portable alarm device 10, wherein the portable alarm device 10 is connected to the central processing unit 3 in a wireless transmission manner, and the central processing unit may transmit the alarm information to the portable alarm device. When the nursing staff leaves the dialysis machine for a short time or leaves a patient who is doing dialysis for a short time, the nursing staff can know the using state of the dialysis liquid at any time by carrying the portable alarm device 10 and can timely come back to increase the dialysis liquid. This allows the caregiver to spend more time dealing with other care tasks.
The method for judging the use state of the hemodialysis solution comprises the following steps: (1) a monitoring device for the condition of use of the hemodialysis solution as described above is provided and a dialysate container containing dialysate is placed on the monitoring device. (2) When the weight measured by the weight sensor 2 is less than a preset threshold value (the preset threshold value refers to the weight when the liquid left in the dialysate barrel cannot meet the requirement of the dialysis dosage and causes the pipette to suck air), the central processing unit 3 sends an alarm instruction to the light alarm device 5, and the light alarm is started. If the light alarm is started, a new dialysate barrel is replaced (for example, the barrel is filled with dialysate), the weight measured by the weight sensor is larger than a preset threshold value, the central processing unit sends an alarm closing instruction to the light alarm device, and the light alarm is stopped. (3) When the starting time of the light alarm exceeds the preset time, the central processing unit sends an alarm instruction to the sound alarm device 6, and the sound alarm is started. If the sound alarm is started, a new dialysate barrel is replaced, and when the weight measured by the weight sensor is larger than a preset threshold value, the central processing unit sends out an alarm closing instruction to the light alarm device and the sound alarm device, and the light alarm and the sound alarm stop.
When the monitoring device further comprises an infusion control device 8, the central processing unit sends an instruction to the infusion control device to start the infusion control device to reduce the pumping speed of the infusion pump or directly stop the operation of the infusion pump at the same time or after the sound alarm is sent in the step 3 of the method.
In a further optimized design, the light alarm in the step 2 is divided into a multi-section alarm mode such as a primary alarm, a secondary alarm, an alarm needing emergency treatment and the like according to different light alarm duration, and the multi-section alarm mode corresponds to different light colors respectively. For example, the light alarm is started and belongs to a primary alarm section within 2 minutes, the color of the light is green, the light is orange when the alarm duration is a secondary alarm section within 2 to 5 minutes, and the light is red when the alarm duration exceeds 5 minutes and belongs to an emergency treatment section. The nursing staff can judge the alarm duration and the emergency degree according to the color of the light so as to arrange the priority of the dialysis liquid barrels to be replaced by different dialysis liquid patients in the dialysis process, and preferentially replace the dialysis liquid barrels used by the patients who have been alarming for a long time. Similarly, the sound alarm of step 3 may also adopt a multi-stage alarm mode, for example, the alarm sound is mild, sharp or sharp, etc. corresponding to different time periods.
An example of the clinical application of the monitoring device for the use state of hemodialysis solution. Turning on the dialysis machine power switch 41; ensuring that the previous disinfection is finished, placing a dialysate barrel filled with dialysate A and B at the corresponding positions of the monitoring equipment, connecting dialysate, selecting a dialysate replacement program, and performing self-inspection; after the liquid replacement procedure is finished, the liquid enters a dialysis device for exhausting; correctly executing the medical advice and inputting dialysis data parameters; starting monitoring equipment of the use state of the dialysate, and setting monitoring parameters according to the model of the dialysate barrel and the like; hemodialysis treatment is started. After receiving supervisory equipment's alarm information during the dialysis, the nursing staff in time knows the liquid quantity in the dislysate bucket to change new dislysate bucket. And returning blood after dialysis is finished, discharging residual liquid in the pipeline, and finishing the cleaning and disinfection of the dialysis machine. The monitoring device has good clinical application value, can well solve the problem that the residual amount of the dialysate in the dialysate barrel cannot be monitored in the prior art, realizes early warning, and has accurate and timely early warning information.
