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

Below by way of specific embodiment, technical scheme is described in detail:

The functional objective of native system is to utilize electronic technology and biotechnology to provide the blood of synchronization to the hemorrhage of operation process Liquid feeds back to be supported.Solve the problem that intraoperative hemorrhage patient blood feeds back not in time, blood supplemental amount is inadequate, reduce patient Owing in art, massive hemorrhage can not supplement in time, fully and the risk of life danger occurs, owing to the blood of feedback is that patient is autologous Blood, reduces blood transfusion cost and the blood transfusion risk of patient in art.

This system is filled safely by amount of bleeding monitoring device, blood recovery pipeline, blood recovery pump, blood filtration net, blood recovery Put and salt water feeder composition.By blood volume monitoring device according to the size of intraoperative blood loss, dynamically regulate the speed of blood recovery pump Degree, to realize the balance of blood recovery amount and amount of bleeding;Blood inputs in patient body, by feeding back after the filtration of filter Safety device carries out pressure and liquid level monitoring to the blood entered in patient body, it is to avoid air enters in patient body, saline supply Device provides isotonic saline solution, to keep the unimpeded of recirculation line and to prevent blood coagulation.(as shown in Figure 1)

During system start-up, feedback pump speed is initialized as 10ml/min, saline supply folder is opened, blood supply clip closure, blood Feedback folder is opened, and pipeline is full of by isotonic saline solution.System monitoring blood recovery liquid level and blood recovery pressure after startup, if blood Feedback liquid level is low or blood recovery pressure is beyond (being to the maximum between 0~500mmHg) in set point, and system sounds alarm is also Closedown blood recovery presss from both sides, to avoid entering in patient body due to air or in recirculation line, pressure anomaly causes the infringement to patient. The voltage-controlled system of blood supply that blood recovery revolution speed is recorded by pressure transducer before pump: as blood supply pressure <-10mmHg, return Defeated pump speed is with the decrease of speed of 10ml/sec, until blood supply is pressed onto and reaches between-10mmHg~+50mmHg, if fed back When pump speed reduces to 10ml/min, blood supply pressure still cannot arrive between-10mmHg~+50mmHg, shows blood collecting amount Little or no, now system is closed blood supply folder, is opened saline supply folder, blood recovery pump with the fixing speed of 10ml/min Degree slowly feeds back saline;As blood supply pressure > 50mmHg, blood recovery pump speed is with the speed increase of 10ml/sec, directly It is pressed onto to blood supply and reaches between-10mmHg~+50mmHg.If feedback pump speed increases to 500ml/min, blood supply Pressure still cannot arrive between-10mmHg~+50mmHg, shows that blood collecting amount is very big, feeds back pump with 500ml/m fixed speed Feed back blood, and send auditory tone cues.When blood supply is pressed between-10mmHg~+50mmHg, blood recovery pump keeps Present speed runs.
