Description

Newborn blood exchange system
Technical Field
The invention relates to the technical field of medical equipment, in particular to a newborn blood exchange system.
Background
Neonatal jaundice is one of the common diseases in clinic, namely, meristematic jaundice and pathological jaundice, under the condition of pathological jaundice, a series of complications can be caused by too fast or too high neonatal bilirubin level, and a serious infant has the risk of bilirubin encephalopathy, so that the serious infant needs to be hospitalized for manual intervention, namely, a common blue light irradiation therapy, albumin infusion, eating of related traditional Chinese medicines and the like. However, if the bilirubin level is extremely high, the conventional method cannot effectively reduce the bilirubin level, and the infant patient needs to be treated for a blood exchange.
The hemorrhaging treatment is one of important treatment measures for clinically treating the children with hyperbilirubinemia, and the timely and efficient hemorrhaging treatment has important significance for preventing the generation of bilirubin encephalopathy of the newborn. However, at present, no complete equipment is available for clinical use in clinic, manual operation is adopted in many cases, and the automation degree is low. Firstly, a unit with better conditions can use a blood transfusion pump at a blood transfusion end, but no related equipment and materials are available at an arterial blood drawing end, most of the units manually use an injector to draw blood, so that the labor is consumed, and the blood drawing speed cannot be guaranteed; secondly, in the whole operation process, a medical staff is required to continuously switch the whole blood infusion and the blood plasma infusion; thirdly, the whole blood changing operation needs to detect the blood specimen of the infant for many times, the risk of infection is increased when the artery interface is disconnected, and the operation is also complicated; fourthly, the extracted waste blood is often extracted in a needle cylinder and cannot be collected well in a centralized way; fifthly, the whole cost of manpower and material resources is high, the preparation time is long, the process is complicated, and the stability of the hemodynamics of the children patients cannot be ensured.
The general process of neonatal exchange is: the infant patient generally establishes two venous pathways, one arterial pathway, the arterial pathway and the venous pathway are not on the same side, the first venous pathway is used for infusing blood products, the second venous pathway is used for infusing maintenance liquid containing sugar, and the arterial pathway is used for drawing blood; the whole blood and the plasma need to be alternately infused according to a certain proportion, the speed of vein entry and the speed of artery exit are consistent, the balance of the blood system of the child patient is ensured, and the risk of sodium citrate poisoning is caused due to the infusion of a large amount of stock blood, so that the blood coagulation function of the child patient is abnormal, and therefore the calcium agent and the sodium citrate can be infused into the second vein for antagonism; when blood is drawn from the infant at the arterial end, the blood is easy to coagulate in the pipeline, so heparin sodium is additionally added for anticoagulation, and the pipeline is prevented from being blocked.
