Compared with prior art, the utlity model has following beneficial effect:
Device is surveyed in the leakage blood examination that this utility model proposes; Main casing is made of one piece by transparent PC material; Except that first side plate and second side plate; The outer surface at all the other positions all applies one deck non transparent layer, has so not only guaranteed to be convenient to carry out the light transmission that light detects, and has guaranteed that again leakage blood examination survey device has good sealing; In addition, leaking blood examination survey device is to be formed by connecting main casing, loam cake and lower cover, and building block reduces, and is simple in structure, and assembling easily, and is easy to maintenance.
Description of drawings
Fig. 1 is the perspective exploded view of this utility model;
Fig. 2 is the schematic perspective view of this utility model.
The specific embodiment
In conjunction with illustrated in figures 1 and 2; Device is surveyed in the leakage blood examination that this utility model proposes; It comprises: by being arranged on the test section 11 in the haemodialysis control unit JIKE and being exposed at the main casing 10 that the outer connecting portion 12 of haemodialysis control unit JIKE is formed outward, and test section 11 and connecting portion 12 are made of one piece; Fixedly install a fixing head 13 between test section 11 and the connecting portion 12, can device be surveyed in the leakage blood examination that this utility model proposes through fixing head 13 and be fixed on the haemodialysis control unit; In addition, connecting portion 12 is cylindric, and its upper end is screwed together with loam cake 20 through O type circle 40, gland 30 successively, through the upper end sealing of loam cake 20 with connecting portion 12; And the lower end of test section 11 connects bonnets 60 through sealing gasket 50, uses screw 70 that sealing gasket 50, bonnet 60 are fixed on the lower end of test section 11, with the lower end sealing of test section 11.Therefore, form an annular seal space between main casing 10, loam cake 20 and the bonnet 60.
First discharging tube 141, second discharging tube 142 and the feed tube 15 in communication seals chamber are set on main casing 10.
The operation principle of this utility model is following:
The dialysis waste liquid of from dialyser, discharging gets into from feed tube 15 and leaks the annular seal space that devices are surveyed in blood examinations, flows out annular seal spaces from first discharging tube 141, second discharging tube 142 then.When not having blood in the dialysis waste liquid; It is water white liquid; Therefore; The white light that radiating circuit plate 80 sends sees through the waste liquid of dialysing in first side plate 111, the annular seal space, second side plate 112 is received 90 receptions of circuit board, and the light that this moment, circuit board for receiving 90 received also is white light.When in the dialysis waste liquid blood being arranged; The dialysis waste liquid will become redness; The white light that radiating circuit plate 80 sends; See through the waste liquid of dialysing in first side plate 111, the annular seal space, second side plate 112 becomes red light, what this moment, circuit board for receiving 90 received is red light, sends the alarm signal that blood takes place to leak in a prompting after sensing red light by the color reaction device on the circuit board for receiving 90.
In leaking the process that blood examination surveys, if produced bubble in the annular seal space, then can discharge, thereby guarantee the accuracy that detects from first discharging tube 141 or second discharging tube 142.
The above is merely the preferred embodiment of this utility model; Not in order to restriction this utility model; Any modification of being done within all spirit and principles at this utility model, be equal to replacement and improvement etc., all should be included within the protection domain of this utility model.
