Description
Technical field
The present invention relates to a kind of device that records out blood flow, relate in particular to the device that records out blood flow in a kind of sham operated.
Background technology
Hemorrhage unavoidably in surgical operation, and a large amount of hemorrhage entail dangers to patient life and affect prognosis.For reducing amount of bleeding, therefore the application of controlled hypotension technology comes into one's own, but calculate blood volume method there be limited evidence currently of in research, classical way is sucked blood and is then weighed and calculate with dry gauze, the method in operation rough estimation still can, but for studying some drugs or the technology intervention effect to amount of bleeding, its degree of accuracy is poor, especially certain medicine of research at a time between when amount of bleeding in the intervention of section, degree of accuracy is thicker.And search in the literature again and study without other schemes.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, the device that records out blood flow in a kind of sham operated is provided.
The object of the invention is to be achieved through the following technical solutions: the device that records out blood flow in a kind of sham operated, this device comprises triple channel stopcock, syringe, pin type linker, venous detaining needle, small syringe, buret, PE pipe, three ends of triple channel stopcock connect respectively PE pipe, small syringe, syringe, the other end of syringe is connected with pin type linker, the external venous detaining needle of pin type linker; Buret is placed in venous detaining needle below.
Further, small syringe fills heparin sodium.
Further, in syringe, fill with heparin sodium.
This device designs for the collection of amount of bleeding, and simulation blood capillary oozing of blood is also collected, and improves the degree of accuracy that amount of bleeding is calculated, and in the time of controlled hypotension, as required sometime or the time period all can accurate Calculation amount of bleeding.The present invention makes simply, and with low cost, degree of accuracy is high, there will not be blood coagulation in metering process, is applicable to each medical colleges and schools and research institution and carries out the research of medicine or other intervention means, is easy to promote.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
In figure, triple channel stopcock 1, syringe 2, the pin type linker 3 of processing, venous detaining needle 4, small syringe 5, buret 6, PE pipe 7, three-way cock 10.
Detailed description of the invention
In a kind of sham operated, record out the device of blood flow, this device comprises triple channel stopcock 1, syringe 2, pin type linker 3, venous detaining needle 4, small syringe 5, buret 6, PE pipe 7, three ends of triple channel stopcock 1 connect respectively PE pipe 7, small syringe 5, syringe 2, the other end of syringe 2 is connected with pin type linker 3, the external venous detaining needle 4 of pin type linker 3; Buret 6 is placed in venous detaining needle 4 belows.
Small syringe 5 fills heparin sodium, manages 7 residual blood, anti-hemostasis-coagulation for cleaning PE.
In syringe 2, fill with heparin sodium, blood is put in one end, and the other end flows out heparin sodium, prevents pin type linker 3 and venous detaining needle 4 places blood coagulation.
Blood capillary in venous detaining needle 4 simulation experiment animal bodies, is equivalent to many places, visual area blood capillary and is compiled in a place, is convenient to collect.Because trickle in venous detaining needle contains a large amount of heparin sodiums, can there is not blood coagulation blocking pipe.
The device that records out blood flow in a kind of sham operated of the present invention, work process is as follows:
Before blood-letting, small syringe 5 fills heparin sodium, rotates the three-way cock 10 on triple channel stopcock 1, and passage a is communicated with passage c, and passage b closes, and promotes the piston of small syringe 5, makes heparin sodium clean PE pipe 7, prevents from managing the blood coagulation of 7 places at PE.
When blood-letting, in syringe 2, fill with heparin sodium, rotate the three-way cock 10 on triple channel stopcock 1, passage a is communicated with passage b, and passage c closes, now, blood by PE manage 7 and triple channel stopcock 1 enter syringe 2, in syringe 2, owing to having injected blood, heparin sodium is discharged in buret 6 by pin type linker 3 and venous detaining needle 4, the volume of the blood of putting into is the volume of buret 6 heparin sodiums.
Claims (3)
