Description
Technical Field
The utility model belongs to the technical field of medical instrument, specifically relate to a sample pipeline for hemodialysis machine quality of water on-line measuring.
Background
At present, most of personnel related to hemodialysis rooms take samples after the water inlet pipe is detached from the connection part of a circulating pipeline after the hemodialysis machine is stopped when water quality detection is carried out on a water inlet of each hemodialysis machine, so that the operation is troublesome, water leakage, pollution and poor accuracy are easy, great risks exist, online sampling can be realized without stopping the hemodialysis machine, and the problems can be avoided by direct online detection.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to the above-mentioned problem, provide a sample pipeline for hemodialysis machine quality of water on-line measuring, need not to shut down and tear open and can realize on-line sampling and detection under the condition of managing.
The utility model discloses a realize through following technical scheme:
the utility model provides a sample pipeline for hemodialysis machine quality of water on-line measuring, includes the main line, its characterized in that: the two ends of the upper surface of the Y-shaped pipe are respectively communicated with the main pipeline through a bypass water inlet battery valve and a bypass water outlet battery valve, and a cleaning water outlet battery valve is arranged at one end of the lower surface of the Y-shaped pipe; y-shaped pipes which are close to the lower parts of the bypass water inlet battery valve and the bypass water outlet battery valve are also respectively communicated with a cleaning pipe through a cleaning water inlet battery valve; the middle part of the Y-shaped pipe connected with the bypass water inlet battery valve is communicated with the sampling pipe, and the sampling pipe is provided with a sampling electromagnetic valve.
Furthermore, the connection end of the sampling tube and the Y-shaped tube is obliquely arranged downwards, and the position of the sampling electromagnetic valve is higher than the position of the connection point of the sampling tube and the Y-shaped tube.

Detailed Description
The invention will be further described with reference to the following specific examples and the accompanying drawings.
As shown in figure 1, a sample pipeline for hemodialysis machine water quality on-line measuring, including main line 1, its characterized in that: the upper two ends of the Y-shaped pipe 2 are respectively communicated with the main pipeline 1 through a bypass water inlet battery valve 3 and a bypass water outlet battery valve 4, and a cleaning water outlet battery valve 7 is arranged at one end of the lower surface of the Y-shaped pipe 2; the Y-shaped pipe 2 which is close to the lower parts of the bypass water inlet battery valve 3 and the bypass water outlet battery valve 4 is also communicated with a cleaning pipe 8 through a cleaning water inlet battery valve 9; the middle part of the Y-shaped pipe 2 connected with the bypass water inlet battery valve 3 is communicated with the sampling pipe 5, and the sampling pipe 5 is provided with a sampling electromagnetic valve 6.
The connection end of the sampling tube 5 and the Y-shaped tube 2 is arranged obliquely downwards, and the position of the sampling electromagnetic valve 6 is higher than the position of the connection point of the sampling tube 5 and the Y-shaped tube 2.
The pipe diameter of the Y-shaped pipe 2 is smaller than that of the main pipeline 1.
The pipe diameter of the sampling pipe 5 is smaller than that of the Y-shaped pipe 2.
Before use, the bypass water inlet cell valve 3, the bypass water outlet cell valve 4 and the sampling electromagnetic valve 6 are closed, the cleaning water inlet cell valve 9 and the cleaning water outlet cell valve 7 are opened, residues in the Y-shaped tube 2 are cleaned by cleaning water entering from the cleaning tube 8, and the flow direction of the cleaning water is shown in the direction of a double arrow in fig. 1, so that sampling detection errors are reduced. After the cleaning is finished, the cleaning water inlet battery valve 9 is closed, and the cleaning water outlet battery valve 7 is closed after a period of time delay. Then the bypass water inlet cell valve 3, the bypass water outlet cell valve 4 and the sampling electromagnetic valve 6 are opened, the sampled water output from the sampling pipe 5 is subjected to water quality on-line detection, and the flow direction of the sampled water is shown as the direction of a single arrow in the figure 1.
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, and those skilled in the art should be equivalent replacement modes without departing from the spirit and principles of the present invention.
