Abstract
The invention relates to a synchronous blood doping system applied to a haemorrhage patient in a surgery. The synchronous blood doping system applied to the haemorrhage patient in the surgery resolves the problems that blood doping for the haemorrhage patient in the surgery is not timely and the supplemented blood is not sufficient, and reduces the life risks generated when the blood can not be supplemented timely and sufficiently for the patient with massive haemorrhage. The transfused blood is the autoblood of the patient, so that the blood transfusion cost and transfusion risks are reduced for the patient in the surgery. The synchronous blood doping system applied to the haemorrhage patient in the surgery is composed of a bleeding amount monitoring device, a blood doping pipeline, a blood doping pump, a blood filtering net, a blood doping safety device and a saline feeding device. The bleeding amount monitoring device dynamically adjusts the speed of the blood doping pump according to the bleeding amount in the surgery to achieve balance between the blood doping amount and the bleeding amount. The blood doping safety device monitors the whole blood doping process, prevents abnormal pressure of the pipeline and prevents air from entering the body of the patient. The saline feeding device plays a role in keeping the blood doping pipeline through and preventing bleed from coagulation.

Detailed description of the invention
By specific embodiment, technical scheme of the present invention is elaborated below:
The functional objective of native system is to utilize electronic technology and biotechnology to provide synchronous blood recovery support to the hemorrhage of operation process.Solve the problem that intraoperative hemorrhage patient blood feeds back not in time, blood supplemental amount is inadequate, reduce patient because massive hemorrhage in art can not supplement the risk that occurs life danger in time, fully, because the blood feeding back is the autologous blood of patient, reduce patient's blood transfusion cost and blood transfusion risk in art.
This system is made up of amount of bleeding monitoring device, blood recovery pipeline, blood recovery pump, blood filtration net, blood recovery safety device and salt water feeder.By blood volume monitoring device, according to the size of intraoperative blood loss, the speed of dynamic adjustments blood recovery pump, to realize the balance of blood recovery amount and amount of bleeding; Blood inputting in patient body after the filtration of filter, by feeding back safety device, the blood entering in patient body is carried out to pressure and liquid level monitoring, avoid air to enter in patient body, provide isotonic saline solution by salt water feeder, to keep the unimpeded of recirculation line and to prevent blood coagulation.(as shown in Figure 1)
When system start-up, feed back that pump speed is initialized as that 10ml/min, saline supply with that folder is opened, blood supply clip closure, blood recovery folder open, pipeline is full of by isotonic saline solution.After starting, system monitoring blood recovery liquid level and blood recovery are pressed, if blood recovery liquid level is low or blood recovery pressure exceeds in set point (being to the maximum between 0～500mmHg), sound alarm close blood recovery folder of system, to avoid entering in patient body or recirculation line internal pressure causes the infringement to patient extremely due to air.Blood recovery revolution speed by pump before the blood supply pressure-controlled that records of pressure transducer: in the time that blood supply is pressed <-10mmHg, feed back the decrease of speed of pump speed with 10ml/sec, until blood supply is pressed onto between reach-10mmHg～+ 50mmHg, if when feedback pump speed reduces to 10ml/min, blood supply is pressed between still cannot arrive-10mmHg～+ 50mmHg, show that blood collecting amount is little or do not have, now system closing blood supply presss from both sides, opens saline supply folder, blood recovery pump slowly feeds back saline with the fixed speed of 10ml/min; In the time that blood supply is pressed > 50mmHg, blood recovery pump speed is with the speed increase of 10ml/sec, until blood supply is pressed onto between reach-10mmHg～+ 50mmHg.If when feedback pump speed increases to 500ml/min, blood supply is pressed between still cannot arrive-10mmHg～+ 50mmHg, shows that blood collecting amount is very large, feed back pump and feed back blood with 500ml/m fixed speed, and the prompting of sounding.When between be pressed in-10mmHg of blood supply～+ 50mmHg, blood recovery pump keeps present speed operation.
