Description

Peritoneal dialysis equipment and dialysate bag subassembly

Technical Field

The utility model relates to the field of medical equipment, especially the auxiliary technology of peritoneal dialysis treatment.

Background

End-stage renal disease will cause the body to lose the function of expelling toxins through the kidneys, resulting in uremic toxins, water retention, and metabolic disorders such as minerals, electrolytes, etc. If these toxic metabolic wastes cannot be discharged in a timely manner, they will lead to death of the patient in severe cases. In the prior medical technology, the uremia toxin and water are usually removed by dialysis, the electrolyte and acid-base balance of the organism is kept, and the stable environment in the organism is maintained.

Peritoneal dialysis is a common form of dialysis used to replace kidney function. In peritoneal dialysis, sterile dialysate is injected into the abdominal cavity of a patient. The peritoneum serves as a natural dialyzer, metabolic waste products such as uremic toxins and various ions are dispersed or convected into the dialysate through the peritoneum, while water is removed to the peritoneal cavity through osmotic gradients. The spent dialysate is intermittently or continuously replaced with fresh dialysate to complete the peritoneal dialysis exchange process. Peritoneal dialysis usually needs 2-5 times a day, has certain requirements on environment and cleanliness of an operation process, can be automatically completed by a patient at home, greatly saves medical resources, is beneficial to maintaining normal social life of the patient, and has better life quality, thereby being widely applied in various countries in the world.

However, the peritoneal dialysis operation at present depends greatly on the patient himself, and the patient needs to adopt a constant temperature box or a preheating bag to heat the dialysate in advance, which takes 30 minutes to 2 hours; simultaneously sterilizing the environment and operators; before operation, the dialysate bag is weighed, and then connected with a dialysate pipeline to start dialysis operation; weighing the waste liquid bag after the operation is finished, manually recording and calculating the ultrafiltration volume of each time; in addition, at ordinary times, the patient or an assistant thereof needs to observe whether the waste fluid bag is clear (light transmittance) by eyes to judge whether the properties of the dialysate are normal or not so as to warn the occurrence of peritonitis. However, the traditional peritoneal dialysis operation mode at present basically depends on manual operation, which not only puts higher requirements on the independence and the experience of an operator, but also has complex procedures and takes time; in addition, in the aspect of preheating the peritoneal dialysis solution, the proper temperature is unreliable, the excessively low or high dialysate can be harmful to the human body and cause complications, and once the dialysate with the uncomfortable temperature is sensed to be infused into the abdominal cavity, the dialysis operation can only be suspended, and the treatment is interfered; in the light transmittance judgment of the peritoneal dialysis solution, demands are made on the eyesight and judgment of the operator, and the operator cannot be ensured to early detect turbid peritoneal dialysis solution (key signs of peritonitis) and treatment may be delayed.

The

pressure sensors

30c and 30d avoid the positions where the accommodating grooves are formed in the box body 302, so that the

pressure sensors

Preferably, the periphery of the cover 301 and/or the box 302 includes an upstanding hard or soft lip projecting from the hard upper surface. More preferably, the edge of the cover 301 and the edge of the box 302 can be connected by a zipper, so that the cover 301 is folded to cover the box 302 to form a closed state, thereby accommodating the inlet line fastener 20, the living room disinfecting device 40, the real-time dialysate metering suspension device 50 and the dialysate preheating device 60.

It will be appreciated that the rim is not required and that the receiving channel in the housing 302 may be designed to be deep so that the upper surface of the items received therein is flush with the rigid upper surface of the housing 302.

Preferably, the cover 301 is provided with receiving grooves corresponding to each other in shape and position, so that when the cover 301 is folded to cover the box 302, the receiving grooves on the cover 301 and the receiving grooves on the box 302 can be matched one to form a space for receiving the articles. This way, the thickness of the kit as a whole can be reduced while ensuring that the rigid upper surfaces of the cover 301 and the case 302 are flush with each other when unfolded.

In a preferred embodiment, the overall size of the kit may be up to about 200mm 100mm 50mm, provided that the article is received. It can be understood that the above dimensions are not limitations of the technical solution of the present invention, and the portability can be considered for reasonable selection on the premise of satisfying the requirements of peritoneal dialysis operation.

The ideal temperature range is 32-39 ℃ (the optimal implementation temperature is 34-37 ℃). The heating bag can be made into a bath cap form so as to be convenient for putting in and wrapping the dialysate bag and taking out the dialysate bag conveniently.

The heating bag 60 may be a graphene electric heating bag, and in this case, a power supply needs to be provided for the electric heating bag, and for example, an on-board DC12V cigarette lighter connector and a 220V/50Hz dual-purpose power supply connector are preferably provided for the heating bag to satisfy various use occasions.

The heating bag 60 may also be implemented using the principle of chemical heating. For example, the heating bag is designed to include a separate heat generating agent chamber and a water storage chamber, and the heat generating agent can generate heat when it encounters water. The specific material selection of the heat generating agent may be any one of the prior art or may be obtained from a commercially available source, such as quicklime, without limitation.

The temperature control valve can adopt a sensor-electric control valve form, and can also adopt a bimetal temperature-saving valve form.

When the heating bag 60 preheats the dialysate to a proper temperature, the dialysate can be heated without using the real-time heating module of the inlet line clip 20 in a room temperature environment. Of course, the inlet line clip 20 still needs to be clamped outside the inlet line 102a during use to collect data such as temperature, flow rate, etc. and transmit the data to the monitoring terminal 70.

When time does not allow the time to use alone that shower cap formula graphite alkene electric heating bag 60 preheats, the dislysate bag subassembly that uses moreover is the embodiment of the utility model provides a during the dislysate bag subassembly with heating core, can directly adopt income liquid pipeline buckle 20 to heat.

According to the weight change curve and the mutual logic sent by the liquid inlet pipeline buckle 20 and the weighing device 30, the monitoring terminal 70 automatically judges which operation type is (namely, judges the operation intention of the patient), automatically judges the current user operation stage according to the current state of the curve, and calculates and uploads the actual weight change curve data and the operation type data.

Fig. 5 is a graph comparing the weight change curves at different operating stages for several exemplary types of operation.

Aiming at standard operation F1, no-drainage (single-filling) operation F2, secondary (or multiple) drainage operation F3, secondary (or multiple) filling operation F4, no-filling (single-drainage) operation F5, multiple-filling and drainage alternate operation F6 and rapid exchange operation F7, time t is taken as an abscissa, weight L of a dialysate bag or a waste liquid bag is taken as an ordinate, weight change curves of the dialysate bag and the waste liquid bag are displayed, wherein a dotted line corresponds to the weight change curve of the waste liquid bag, and a solid line corresponds to the weight change curve of the dialysate bag. The time t is divided into five phases: a preparation phase T1, a flushing phase T2, a drainage phase T3, a filling phase T4 and a completion phase T5. The above curves are prestored as reference data in the monitor terminal 70.

During the peritoneal dialysis procedure, the monitoring terminal 70 monitors the change in weight of the dialysate bag and the waste bag in real time, compares the reference data, identifies the current procedure type and monitors the status of the procedure, in the following manner, for example:

1. the bag weight changes are the same for both the preparation phase T1 and the flush phase T2 for each type of procedure, where the dialysate bag is full in weight for the preparation phase T1 and the waste bag is near zero in weight, so the type of procedure is not generally identified and recorded in both phases, but the end of both phases is identified and marked.

2. When the weight of the waste liquid bag is kept unchanged for a period of time and the weight of the dialysate bag is gradually reduced after the preparation phase T1 and the flushing phase T2 are ended, the current operation phase is identified as a liquid filling phase, the current operation type may be a single liquid filling (no drainage) operation F2, a multiple liquid filling and drainage alternating operation F6 or a rapid exchange operation F7, and the operation type is further confirmed by combining the weight change amplitude of the liquid bag and the characteristics of the subsequent phases:

2.1, after the liquid filling stage T4 is finished, the weights of the waste liquid bag and the dialysate bag are not changed, wherein the weights of the waste liquid bag and the dialysate bag are close to zero, the current operation stage is identified as a finishing stage, and the current operation type is a drainage-free (single liquid filling) operation F2;

2.2, when the filling phase T4 is finished, if the weight of the dialysate bag is greatly reduced (almost reduced to zero), identifying the current operation type as fast exchange operation F7, and then the weight of the waste bag is greatly increased, further confirming that the operation type is fast exchange operation F7;

2.3, when the filling period T4 is finished and the weight of the dialysate bag is slightly reduced, identifying that the current operation type is a multiple filling and drainage alternate operation F6, then slightly increasing the weight of the waste liquid bag, and further confirming that the operation type is a multiple filling and drainage alternate operation F6.

3. When the weight of the dialysate bag remains unchanged for a period of time after the preparation phase T1 and the flushing phase T2 are completed, the current operation phase is identified as the drainage phase, the current operation type may be standard operation F1, secondary (or multiple) drainage operation F3, secondary (or multiple) filling operation F4 or single drainage operation F5, and the operation type is further determined by combining the change amplitude of the weight of the bag and the characteristics of the subsequent phases:

3.1, when the weight of the waste liquid bag is not increased continuously in the drainage process, but is increased firstly, then is kept unchanged for a short time and then is increased continuously, the current operation type can be identified as secondary (or multiple) drainage operation F3;

The monitoring terminal 70 obtains the weight change curves of the dialysate bag and the waste bag in the actual process by means of data sent by the weighing device and the real-time dialysate metering suspension device. Specifically, prior to the peritoneal dialysis operation, the dialysate real-time metering suspension or weighing device weighs the initial weight of the dialysate bag and sends it to the monitoring terminal 70 via bluetooth or other short-range wireless data transmission means, and the monitoring terminal 70 can calibrate the reference curve shown in fig. 5 based on the initial weight. In the peritoneal dialysis operation process, the real-time dialysate measurement suspension device records the weight change of the dialysate bag in real time along with time and sends the weight change to the monitoring terminal 70 in real time, and meanwhile, the weighing device weighs the weight change of the waste liquid bag in real time and sends the weight change to the monitoring terminal 70 in real time. The monitor terminal 70 can obtain the weight change curves of the dialysate bag and the waste bag in the actual process based on the received data.

The monitoring terminal 70 also includes a timing module. The monitoring terminal 70 can set a period for performing the peritoneal dialysis operation, for example, once a day, and perform an operation reminder at a set point in time.

The monitoring terminal 70 also includes a remote communication module. The monitoring terminal 70 can set the hospital, the designated medical staff or the family member in advance to carry out the operation auxiliary guidance at a remote place according to the needs of the patient. For example, the audio-video communication module can be used for providing remote video and voice operation guidance for the patient by medical staff and assisting the operation of the instrument according to real-time data.

The monitoring terminal 70 further includes a remote data transmission module for transmitting the real-time recorded irrigation amount, drainage amount, flow rate, temperature, turbidity, abnormal record and the like to a remote data center, such as a data center at a hospital server side or a cloud data center.
