Abstract
The utility model discloses a blood-chamber capacity detection device which comprises an upper cover, a capacity cavity, a connecting sheet, a weighing sensor and a connector, wherein, the upper end of the capacity cavity with a cylindrical cavity is provided with an opening, the opening is connected with the upper cover, the lower end surface of the capacity cavity is connected with the weighing sensor through a connecting sheet, a through hole is arranged at one side on the lower end of the capacity cavity, one end of the through hole is communicated with the cavity chamber of the capacity cavity, and the other end of the through hole is connected with a liquid-outflow connector, the two sides of the upper cover are provided with a through hole that is respectively connected with a liquid-inlet pipe connector and a gas-liquid mixing pipe connector, the through holes on the upper cover are communicated with the cavity chamber of the capacity cavity, another through hole is arranged at the center of the upper cover, and a floater detecter is inserted into the through hole to be fixed with a screw cap. The utility model has simple structure, and convenient and rapid utilization; when in use, the accuracy of the weighing sensor is primarily judged, and then the measurement of the blood-chamber capacity of a dialyser is performed, thereby improving the correctness of the test of the blood-chamber capacity.
Description
Technical field
The utility model relates to a kind of pick-up unit, particularly a kind of pick-up unit that is applicable to that the haemodialyser multiplexing machine detects the blood chamber vol of dialyzer in cleaning process.
Background technology
Have some capillary fiber pipes in the dialyzer, blood filters in these capillary fiber pipes, reach the purpose of cleaning blood, yet in use some capillary fiber pipe can stop up, the dialyzer effective blood volume is reduced, can't accurately judge whether dialyzer can also continue use, whether can also reach result of treatment if just can't not learn the true blood chamber vol of dialyzer after tested this moment.And present blood chamber vol detects not from imitating function, can not guarantee the accuracy of measurement data, so need to improve.
Summary of the invention
The purpose of this utility model is to disclose a kind of simple in structure, cleans in the dialyzer process pick-up unit that can detect its blood chamber vol at the haemodialyser multiplexing machine.
For reaching the foregoing invention purpose, the technical scheme that is adopted is: a kind of blood chamber vol pick-up unit, comprise loam cake, capacity chamber, brace, LOAD CELLS and joint, capacity chamber upper end open with tubular cavity, opening part is connected with loam cake, the capacity chamber lower surface is connected with LOAD CELLS by brace, capacity chamber lower end one side has through hole, one end of through hole is communicated with the chamber of capacity chamber, the other end is connected with liquid outlet joint, the loam cake both sides have two through holes that are connected with gas-liquid mixing tube joint with the feed tube joint respectively, on the through hole that covers be communicated with the chamber of capacity chamber, loam cake central authorities have through hole, and the float detecting device inserts in this through hole and by fixed by nut.
The float detecting device is connected and composed by ball float, guide rod and several tongue tube detecting devices, and ball float is socketed on the guide rod and is slidingly matched, and several tongue tube detecting devices place in the guide rod, and the tongue tube detecting device is connected on the watch-dog by lead.Float detecting device and loam cake junction are provided with O-ring seal.
During use, dialyzer is connected on the feed tube joint of cutting out, the gas-liquid mixed pipe adapter is connected with air pump and gas outlet, opening air pump is pressed into gas in the capacity chamber, capacity chamber is carried out emptying process, surplus liquid in the capacity chamber is discharged from liquid outlet joint, open feed tube after closing air pump and liquid outlet joint, blood in the dialyzer all flows in the capacity chamber, gas in the capacity chamber is discharged from the gas-liquid mixed pipe adapter, detect liquid level by the float detecting device this moment and whether reach and setting value, can learn whether the blood chamber vol is accurate in the dialyzer after comparing in conjunction with the detected weight numerical value of LOAD CELLS.
Of the present utility model simple in structure, easy to use, quick, in measuring process, at first judge the accuracy of LOAD CELLS, the measurement of carrying out the blood chamber vol of dialyzer has again improved the accuracy of blood chamber vol test.
