Described weighing device comprises two LOAD CELLSs, flat board 10 and pallet 2, described two LOAD CELLSs respectively have up and down a screw of a M8, described two LOAD CELLSs are fastened on described dull and stereotyped 10 by screw symmetry below, described pallet 2 by two screws above LOAD CELLS be fixed on two LOAD CELLSs above, described LOAD CELLS is S type LOAD CELLS, model is MS-1, and precision is 0.03%, and 10Kg be take interior error as 3g.
As shown in Figures 4 and 5, the control system of controlling the peritoneal dialysis machine of above-mentioned cooperation CAPD comprises PLC and expansion module thereof, touch screen, regulated power supply, alarm and relay, described PLC and expansion module thereof respectively with described touch screen, regulated power supply is connected with alarm, described PLC and expansion module thereof are also respectively by described relay and drain pipe clamping electromagnetic valve, injecting pipe clamping electromagnetic valve is connected with heater, described PLC and expansion module thereof are connected with the LOAD CELLS in weighing device by amplifier, described amplifier model is YHG-101, output signal is 4-20mA, described PLC and expansion module thereof are connected with the thermal resistance in heater by transmitter, described PLC and expansion module thereof are S7-200PLC and expansion module thereof, model is Siemens 6ES7214-1AD23-0XB0 and 6ES7231-0HC22-0XAB, described Siemens 6ES7214-1AD23-0XB0 is CPU module, being mainly used in storage and execution programs, control output, described 6ES7231-0HC22-0XAB is 4 tunnels analogy amount data acquisition modules, be mainly used in gathering the data of fluid temperature and drainage-fluid weight, and sent to CPU, then by CPU, it is processed.
The work process of this example:
1. the 0th bag of medicinal liquid is manually injected in human abdomen; (the 0th bag refers to before connecting machine, newly injects one bag of medicinal liquid in abdominal part, waits for by drain);
2. dialysis solution used is kept flat on hot plate, corresponding injection hose is put into and injected pipe clamping electromagnetic valve 9, cover bonnet, conduction hose is put into drain pipe clamping electromagnetic valve 8, cover bonnet, and drainage bag is lain on the pallet 2 in weighing device;
3. on touch screen, set relevant parameter: 0 bag of medicinal liquid is deposited abdomen time, 0 bag of medicinal liquid drainage time, the 1st bag of medicinal liquid and deposited abdomen time, medicine liquid heating temperature etc.;
4. the flexible pipe on dialyzate bag is connected with the Dialysis tubing on human body;
5. pipeline aerofluxus: be about to dialyzate bag with the valve on pipeline, break into two with one's hands, now the valve of the Dialysis tubing on human body should be in closure state, allow medicinal liquid from pipeline, flow in drainage bag, to get rid of the air in pipeline, till being 2kg by the artificial weight that claims medicinal fluid bag;
6. " zero clearing " button that the stop button on point touching screen, and click is weighed on picture, equipment is started working, and drain pipe clamping electromagnetic valve 8 and injection pipe clamping electromagnetic valve 9 clamp flexible pipe, and heater starts heating, and PLC starts timing;
7. according to the setting-up time on touch screen, 0 bag of medicinal liquid is deposited the abdomen time and is arrived, and drain pipe clamping electromagnetic valve 8 is opened, and starts drain;
8.0 bags of medicinal liquid drainage times arrive, and drainage flow is sufficient, alarm free, and drain pipe clamping electromagnetic valve 8 is closed, and injects pipe clamping electromagnetic valve 9 and opens, and starts to inject new medicinal liquid;
After 9.10 minutes, inject completely, start timing, deposit the abdomen time arrive when the 1st bag of medicinal liquid, alarm sends signal, the drain of prompting client need;
10. patient is put into drainage bag in ground geobasin, starts drain;
11. drains finish, and disconnect the connection of the Dialysis tubing on medicinal fluid bag top hose and human body, and flexible pipe is taken out from drain pipe clamping electromagnetic valve 8 and injection pipe clamping electromagnetic valve 9, treat complete;
0 drain weight of 12. records and drain weight for the first time.
Following table is the state table of opening, break of the Dialysis tubing valve that drain pipe clamping electromagnetic valve, injection pipe clamping electromagnetic valve and human body carry in above process.
This instrument coordinates CAPD at night, to carry out peritoneal dialysis treatment, adopt daytime manual mode to treat, and connect just before going to bed at night this instrument, will automatically dialyse night, do not need artificial participation, avoid like this patient or the family members liquid of changing dressings of getting up midnight, ensured that patient's sleep is had a rest, also can guarantee that dialysis fully, there will not be edema simultaneously.
Above the invention embodiment is had been described in detail, but described content is only the preferred embodiment of the invention, can not be considered to for limiting the practical range of the invention.All equalization variations of doing according to the invention application range and improvement etc., within all should still belonging to the patent covering scope of the invention.
