Description

Blood perfusion ware fixing device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a blood perfusion device fixing device.

Background

In the medical field, a blood perfusion treatment method is generally used for treating diseases such as acute and chronic drug poisoning and uremia. The method is that the blood of a patient is led into a dialyzer through a pipeline, the blood is purified through the adsorption effect of an adsorbent in the dialyzer, and the dialyzed blood returns to the body through the pipeline, so that large and medium molecular toxins in the blood are removed, and the purpose of treatment is achieved. However, in clinical practice, the hemoperfusion apparatus is sometimes connected as required, and the fixed connection of the hemoperfusion apparatus to the whole commercially available dialysis machine is not designed, and there is no corresponding connector to fixedly connect the hemoperfusion apparatus to the dialysis machine, so that the use is inconvenient, and therefore, medical staff mostly adopt a temporary solution, namely, the blood tank is fixed to the dialyzer by means of the tourniquet strap. Obviously, the method not only easily enables the blood tank to loosen and slide off, has potential safety hazard, but also increases the workload of medical personnel and reduces the working efficiency.

In order to solve the above problems, CN 204193160 discloses a blood tank connector which can effectively fix a blood tank to a dialyzer, but since the connector is designed to the shape of the original cylindrical blood tank, the structure of the clamping portion is single, and the connector can be used only for blood tanks of the previous models. Most of the existing clinics use the Adsorba150C type hemoperfusion apparatus, the hemoperfusion apparatus is in a shuttle-shaped structure, i.e. the middle is thick and gradually reduces along two ends, if the connector is used again, the clamping position of the connector and the outer surface of the Adsorba150C type hemoperfusion apparatus can only generate line contact clamping fixation and is very unstable, the diameter of the hemoperfusion apparatus is continuously reduced along two axial ends, the central position is required to be found during clamping (to keep two ends of the hemoperfusion apparatus balanced), the operation difficulty is increased, and the hemoperfusion apparatus can fall off after being slightly collided due to poor clamping stability, and accidents are caused; CN2016200959766 discloses a fixed connector for a hemoperfusion apparatus and a dialyzer, which is fixed by clamping the hemoperfusion apparatus, and can be fixed in cooperation with the conventional hemoperfusion apparatus; however, a problem with similar clamping arrangements is that excessive clamping forces can damage the side walls of the hemoperfusion cartridge.
