Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, in particular to a blood perfusion device capable of automatic stirring. Background Art

[0002] Blood purification uses a perfusion machine to draw blood out of the human body, pass it through a perfusion device, which is filled with blood-purifying substances, such as adsorbent resins, and then return the blood to the patient. During the purification process, the blood begins to adsorb or purify when it comes into contact with the purifying substance. Under ideal conditions, the purifying substance (resin) is evenly distributed in the uniformly flowing blood, without aggregation or deposition. As the blood flows, the purifying substance moves evenly, thereby fully releasing the purification capacity. However, the purifying substances in blood perfusion often aggregate and deposit due to blood compatibility, nonspecific adsorption, and air cavities. The current blood perfusion device only has a shell and purifying substances. When aggregation and deposition occur, it can only rely on external knocking and slapping, etc., which has very limited effects and consumes manpower. When entering the bubble formation cavity, the deposition and aggregation phenomenon becomes more serious, the purification capacity cannot be released, and even endangers the patient's life safety.

[0003] There are three main reasons: First, the perfusion device needs to be pre-flushed before use. During the pre-flushing and treatment process, it is inevitable that gas will enter. Bubbles entering the perfusion device cause coagulation. At the same time, bubbles form a cavity in the perfusion device, causing blood to coagulate. The coagulated blood accelerates the aggregation and deposition of purification substances, which may affect the treatment effect at best and endanger the patient's life at worst. Second, the purification substance is generally an adsorption resin, or other substances immobilized on the resin. The density of the resin itself is similar to that of blood. During the purification process, the resin is non-specifically adsorbed or adhered to albumin in the blood by surface tension, causing the resin to aggregate and deposit. Third, when coagulation resin aggregates and deposits over a large area.

[0004] In order to protect the patient's life safety, release the purification capacity and achieve the purification effect, it is necessary to solve the aggregation and deposition during treatment and eliminate the threat of bubbles. Chemical methods are complicated and difficult to achieve the purpose. Physical methods such as knocking and colliding from the outside or stirring from the inside can meet the requirements, but the external collision and knocking force is uneven, and the effect of stable dispersion cannot be achieved. The low energy utilization rate causes resource waste. Summary of the invention

[0005] The invention discloses an automatically stirring blood perfusion device, aiming to solve the technical problem that purification substances in blood perfusion often aggregate and deposit and cannot be effectively solved.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:
