Description

Novel blood loop for blood purification

Technical Field

The utility model relates to a blood purification consumable, which belongs to the field of medical instruments, and is mainly used for a blood circuit connected with a filter in the blood purification treatment process.

Background

The novel blood circuit for blood purification is an extracorporeal connecting pipeline used for blood purification treatment of patients, and mainly provides a human body to be connected with a filter, removes certain metabolic waste or toxic substances in the body, and then leads blood back to the body.

Blood is frequently drawn out of the body, and clotting often occurs at the site of filters, venous jugs, tubing, etc., during extracorporeal circulation. But is most commonly coagulated with venous jugs, which occur at up to 23% and are located in the extracorporeal circuit before the return of blood to the patient. The blood coagulation of the venous pot often causes unsmooth blood return of a patient, further causes blood coagulation of the whole pipeline, increases blood loss of the patient, causes the patient to be forced to stop treatment, causes unplanned starting, and influences blood purification treatment effect. And meanwhile, the nursing workload and the economic burden of the patient are increased.

The novel blood circuit is mainly used in the field requiring blood purification treatment.

Compare with ordinary traditional straight type vein kettle, the vein kettle of hypotenuse structure when blood purification treatment, blood can directly not be too high drips into the liquid level, but sneaks into vein kettle blood along hypotenuse kettle inner wall, has increased blood flow, can effectually improve when the blood liquid level is low in the vein kettle, leads to in the kettle blood to form the torrent, and the blood coagulation problem that takes place in kettle wall department.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a blood return pipeline for improving blood coagulation so as to improve the existing straight type

The torrent appears in the blood return pipeline of vein kettle in clinical use to the emergence is congealed to provide a simple structure, convenient to use can effectively improve and appear the blood coagulation, and reduces medical personnel work load and reduce patient's economic burden, supplies the clinical novel blood circuit that need carry out the patient use of blood purification.

The utility model is realized by adopting the following technical scheme:

a novel blood loop for blood purification is formed by sequentially connecting a protective cap, a dialysis connector, a pipeline I, a puncture type sampling port, a pipeline II, a pressure sensor, a pipeline III, a three-way connector, a venous pot component, a pipeline IV, a clamp and a puncture needle connector, wherein a branch pipe component I is arranged on a bypass of the three-way connector, a branch pipe component II is arranged at the upper part of the venous pot component, and the branch pipe component I and the branch pipe component II are respectively formed by a conical connector protective cap, a conical connector, a small clamp and a thin pipe; the venous pot component consists of a pot cover, a pot body and a filtering catcher; the body of the venous pot is a hypotenuse pot, an asymmetric structure is adopted, and a blood outlet on the pot cover is positioned right above the hypotenuse of the pot body for a certain distance.

Furthermore, the novel blood loop for purifying blood is provided with the bevel edge type venous pot, and the assembly position of the pot cover and the pot body is provided with the foolproof step and the limiting groove.

According to the blood purification pipeline blood loop, in the blood purification treatment process of the venous pot, blood cannot directly drop to the liquid level too high, but flows into the blood of the venous pot along the inner wall of the inclined pot, so that the flowing time of the blood is prolonged, and the problem of blood coagulation at the pot wall caused by turbulent flow of the blood in the pot when the liquid level of the blood in the venous pot is too low can be effectively solved. The utility model also has the advantages of simple structure, reliable connection, simple manufacturing process and low production cost.
