Haemodialysis (Hemodialysis), clinic mean that some wastes in blood are removed by semipermeable membrane, blood
Dialysis is a kind of one of safer, easy, widely used blood purification method.During dialysis, doctor needs at any time
Extraction endotoxin is monitored, existing dialysis machine without special endotoxin sample tap, only dialyzate electrolyte sample tap, this
Sample sampling was not only inconvenient, but also be easy to cause the pollution of sample.
Utility model content
In view of the deficienciess of the prior art, the technical problem to be solved by the present invention is to provide a kind of haemodialysis control units
Endotoxin sampling apparatus can facilitate doctor to carry out endotoxin sampling and the pollution of sample.
To achieve the goals above, the utility model is to realize by the following technical solutions：A kind of haemodialysis control unit
Endotoxin sampling apparatus, including threeway socket, plug, pressure head and blood tube, the threeway socket include inlet, liquid outlet and
Acquisition port, the plug and the acquisition port grafting tight fit, the pressure head are covered on the outer end of plug, and removable with acquisition port
Connection is unloaded, one end of the separate acquisition port of pressure head offers the opening for exposing the plug, set on the pressure head of the open outer side
A block is set, the block is connect with pressure head by shaft；It is fitted with blood tube in the inlet and liquid outlet.Work as doctor
When needing sampling, the block in the present apparatus is opened, sampling probe is entered acquisition port across plug extracts sample, and plug has automatic
Closing function effectively can enter acquisition port by dust, after the completion of sampling, block is covered again, prevents dust from polluting plug.
Further, the plug material is medical silica-gel.Silicon rubber has good biocompatibility, non-stimulated, nothing
Poison, without allergic reaction, can effectively prevent dialyzate contaminated
Further, be provided with a limited step in the acquisition port madial wall circumferential direction, the plug be tightly fixed in
The limited step, the pressure head are flexibly connected with the acquisition port by screw thread.When plug carries out multiple repairing weld rear end face meeting
Form many pin holes that can not restore, it is necessary to which at this moment the pressure head being threadedly coupled with acquisition port is removed, pulled out by the plug more renewed
Fall plug, replace with new plug, be finally again threadably secured pressure head, this way it is possible to avoid with changing entire sampling dress
It sets, it is economical and practical.
Further, it is fixed with sealing ring in the inlet and liquid outlet.Sealing ring coordinates with the blood seal of tube, prevents
Dialyzate leaks.
Further, the blood tube is medical spiral barrel.Medical spiral barrel is to the evaporating of dialyzate in pipe, cold
Solidifying, gaseous flow, which is conducted heat, liquid spreads heat invigoration effect.
The beneficial effects of the utility model：
When doctor needs sampling, present apparatus block is opened, sampling probe is entered acquisition port across plug extracts sample, blocks up
Head has the function of self-closed, effectively can enter acquisition port by dust, after the completion of sampling, block be covered again, prevents dust
Pollute plug.
