Abstract
The utility model relates to an extracorporeal circulation blood path and belongs to the technical field of medical devices. The extracorporeal circulation blood path is characterized in that the upper end diameter of an artery ampulla and the upper end diameter of a vein ampulla of the extracorporeal circulation blood path are obviously larger than the lower end diameter of the artery ampulla and the lower end diameter of the vein ampulla, and the upper end and the lower end of the artery ampulla and the upper end and the lower end of the vein ampulla are in inclination connection. An artery blood hose, a vein blood hose, the artery ampulla and the vein ampulla are made of a poly vinyl chloride (PVC) material containing acetyl tributyl citrate (ATBC) non-orthophthalic plasticizer. The extracorporeal circulation blood path is suitable for various hemodialysis machine models, and due to the fact that the PVC material containing the ATBC non-orthophthalic plasticizer is adopted, product safety is guaranteed, and the cost is low.
Description
Affiliated technical field
This utility model relates to a kind of extracorporeal circulation blood circuit, belongs to technical field of medical instruments.
Background technology
Extracorporeal circulation blood circuit is widely used product in the blood purification process clinically.Tremulous pulse kettle and the vein kettle of conventional extracorporeal circulation blood circuit are generally cylindricality or single pyramidal structure, product has selectivity to the haemodialysis control unit type, and the tremulous pulse flexible pipe of conventional extracorporeal circulation blood circuit and vein flexible pipe are the PVC material of DEHP o-benzene plasticiser, and there is the potential safety hazard of genotoxicity and carcinogenecity in product.Though have indivedual enterprises to adopt the PVC material of TOTM plasticizer, material cost is higher relatively.
Summary of the invention
This utility model provides a kind of extracorporeal circulation blood circuit, and it has and is suitable for various haemodialysis control unit types, safety characteristics such as be guaranteed, and material cost is lower.
The technical scheme that its technical problem that solves this utility model adopts is: the tremulous pulse kettle of extracorporeal circulation blood circuit and the upper end diameter of vein kettle adopt gradient to connect obviously greater than lower end diameter between the upper and lower side; Arterial blood flexible pipe, venous blood flexible pipe and tremulous pulse kettle, vein kettle all adopt the PVC material that contains the ATBC non-o-benzene plasticiser.The extracorporeal circulation blood circuit of this structure reached be suitable for various haemodialysis control unit types, security of products is guaranteed and lower-cost purpose.
Description of drawings
Fig. 1 is the structural representation of embodiment.
Among Fig. 1: 1. arterial blood flexible pipe, 2. venous blood flexible pipe, 3. tremulous pulse kettle, 4. vein kettle, 5. upper end, 6. gradient, 7. lower end
The specific embodiment
Below, accompanying drawings performance of the present utility model:
