Abstract
The invention relates to an extracorporeal circulation blood path, and belongs to the technical field of medical apparatuses and instruments. The extracorporeal circulation blood path is characterized in that the diameter of the upper end of an artery pot of the extracorporeal circulation blood path is obviously larger than that of the lower end of the artery pot, the diameter of the upper end of a vein pot of the extracorporeal circulation blood path is obviously larger than that of the lower end of the vein pot, the upper end of artery pot and the lower end of the artery pot are connected through an inclined element, the upper end of the vein pot and the lower end of the vein pot are connected through an inclined element, and artery blood hose pipes, vein blood hose pipes, the artery pot and the vein pot are respectively made of PVC materials containing ATBC. The extracorporeal circulation blood path of the structure is suitable for various hemodialysis machine types. Due to the adoption of the PVC materials containing the ATBC, safety of a product is ensued, and cost is low.
Description
Affiliated technical field
The present invention relates to a kind of extracorporeal circulation blood circuit, belong 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
The invention provides a kind of extracorporeal circulation blood circuit, it has and is suitable for various haemodialysis control unit types, safety characteristics such as be guaranteed, and material cost is lower.
The technical solution adopted for the present invention to solve the technical problems 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 invention:
Upper end (5) diameter of the tremulous pulse kettle (3) of extracorporeal circulation blood circuit and vein kettle (4) adopts gradient (6) to connect obviously greater than lower end (7) diameter between upper end (5) and lower end (7); Arterial blood flexible pipe (1), venous blood flexible pipe (2) and tremulous pulse kettle (3), vein kettle (4) 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.
Claims (2)
1. extracorporeal circulation blood circuit is characterized in that upper end (5) diameter of the tremulous pulse kettle (3) of extracorporeal circulation blood circuit and vein kettle (4) obviously greater than lower end (7) diameter, adopts gradient (6) to connect between the upper and lower side.
2. extracorporeal circulation blood circuit according to claim 1, it is characterized in that: arterial blood flexible pipe (1), venous blood flexible pipe (2) and tremulous pulse kettle (3), vein kettle (4) all adopt the PVC material that contains the ATBC non-o-benzene plasticiser.
