Description
Technical field
The disposable sterilized transfusion of a kind of venous transfusion of the present invention changes pipe, relates to a kind of aseptic pipe that changes that uses in the time of venous transfusion, belongs to the medical apparatus and instruments field.Be particularly related to and a kind ofly use when utilizing venous transfusion wireless monitoring detector and alarm that the liquid in the transfusion drip tube is carried out flow velocity, heating and temperature survey, can Effective Raise flow-speed measurement degree of accuracy, the aseptic transfusion of infusion heating uniformity and temperature survey accuracy changes pipe.
Background technology
At present, in the time of the clinical vein transfusion, the micro computerized intravenous transfusion control device that adopts, when measuring infusion flow rate, all be directly to measure on the basis of existing tube for transfusion, existing measurement to the medicinal liquid flow velocity is all measured by drippage mode in the measurement medicinal liquid dropper, optoelectronic induction Receiver on the transfusion drip tube groove two side and discharger are in the same horizontal line, in the measuring process to transfusion drip speed, mainly be medicinal liquid under action of gravitation in the mode of freely falling body by infrared spy window, then detect the mode of water droplet drippage, because indoor temperature change generated in case, on the transfusion drip tube wall that causes, a large amount of the accumulation globule or water smoke usually appear, because stopping of water smoke and the globule, so that can not accurately detecting water droplet, infrared remote receiver whether drips, so that the medicinal liquid flow velocity is difficult to reach accurate measurement, if and directly carry out the medicinal liquid flow-speed measurement, easily medicinal liquid is produced again and pollute, and the present various devices that transfusion drip tube is controlled, can't the accurately controlling medicinal liquid flow velocity, the mode that at present tube for transfusion is heated, the master has the electric auxiliary heating of employing, warm treasured pastes or makes transfusion drip tube carry out auxiliary heating on thermos flask, this directly to tube for transfusion or infusion bottle, the transfusion bag mode of heating, can cause the non-uniform temperature of infusing, the temperature that more can't accurately controlling medicinal liquid enters human body causes that easily patient does not accommodate malpractice.
Summary of the invention
In order to address the above problem, the disposable sterilized transfusion of a kind of venous transfusion of the present invention changes pipe and provides a kind of and use when utilizing venous transfusion wireless monitoring detector and alarm that the liquid in the transfusion drip tube is carried out flow velocity, heating and temperature survey, can Effective Raise flow-speed measurement degree of accuracy, the aseptic transfusion of infusion heating uniformity and temperature survey accuracy changes pipe.
The disposable sterilized transfusion of a kind of venous transfusion of the present invention changes pipe and is achieved in that the disposable sterilized transfusion of a kind of venous transfusion of the present invention changes pipe by upper sealed joint pipe, accurate impeller, spacing holddown groove, the metal coil pipe, the transfusion measuring tube, spacing measuring flume, the lower seal connection tube, the infusion flow pipe, turbine measuring flume and precision spindle form, upper sealed joint pipe is connected with the infusion flow pipe, the turbine measuring flume places on the infusion flow pipe, accurate impeller places in the turbine measuring flume by precision spindle, the infusion flow pipe is connected by the metal coil pipe with the transfusion measuring tube, spacing holddown groove and spacing measuring flume place respectively on the infusion flow pipe, and the lower seal connection tube places on the transfusion measuring tube.
During use, respectively upper sealed joint pipe is connected with tube for transfusion with the lower seal connection tube, then transfusion liquid turbine measuring flume and the spacing holddown groove on the infusion flow pipe of can flowing through successively, then enter the metal coil pipe, the spacing measuring flume of transfusion on the measuring tube of flowing through at last, liquid is with the accurate impeller propelled in the turbine measuring flume, can measure by photoelectric sensor the flow velocity of liquid, when the needs transfusion liquid stops to flow, can utilize stopping means to make the place's quick-make of spacing holddown groove, the metal coil design, make when heating to liquid, can homogeneous heating, utilize the temperature of temperature sensor in spacing measuring flume can accurately measure the transfusion measuring tube more, reach and improve the accuracy that flow rate of liquid in the venous transfusion dropper is measured, the purpose of infusion heating uniformity and temperature survey accuracy.
Beneficial effect.
One, simple in structure, convenient and practical.
Two, with low cost, be easy to promote.
Three, turbine measuring flume, accuracy and limitation that can the Effective Raise flow-speed measurement.
Four, spacing holddown groove design, can Effective Raise to the accuracy of tube for transfusion flow speed control.
Five, metal coil design, can Effective Raise tube for transfusion temperature the uniformity of heating.
Six, spacing measuring flume design can the thermometric accuracy of Effective Raise tube for transfusion.
