Abstract
The utility model relates to a centrifugal bag provided with integrated blood composition separation and collection. The centrifugal bag is a soft bag which is formed by two layers of plastic film being molded through a high frequency thermal sealing method and provided with functional structures of a separation cavity and a collection cavity, and the sealing and the separation of the collection cavity and the separation cavity are realized through sealing strips. The sealing strips with different shapes are arranged in the both cavities, thereby ensuring that the cavities are divided into different blood composition circulating zones; simultaneously, soft pipes fixed on the centrifugal bag are respectively communicated with the zones and can be connected with other parts of a blood composition collection device, thus flow passages are provided for transmitting the blood composition of different zones. The optimum structural design of the centrifugal bag realizes the integration of separation and collection of the blood composition. The special structure utilizes the principle of highly efficient hydrodynamics, thereby ensuring that the blood and the blood composition in the both cavities can realize highly efficient separation and collection.
Description
Technical field
This utility model relates to a kind of centrifugal assembly with centrifugal separation of blood constituent and collection, and particularly a kind of blood constituent separates and collects incorporate centrifugal bag.
Background technology
In modern blood collecting technology, adopt the isolating method of blood constituent more, promptly the separation of whole blood of being gathered out by the blood donor becomes different compositions, and the composition that needs is taken out, and then remaining component blood is fed back to the blood donor.At present, had the blood that will gather by blood separator blood constituent to be separated, the disposable utensil that cooperates blood separator is based on the cup type two big classes of separating with pocket type, and present separation and collecting efficiency are very unsatisfactory.
Summary of the invention
The purpose of this utility model is the deficiency that exists at the disposable utensil separation bag that cooperates seperator, and a kind of fluid mechanics principle of utilizing is provided, and with the supporting use of novel blood component separator, realizes the centrifugal bag of blood constituent high efficiency separation and collection.
This utility model is to realize above-mentioned purpose by following structure, this blood constituent separates and collects incorporate centrifugal bag, comprise disengagement chamber, collecting chamber, flexible pipe, sealing strip, ellipse hole, reinforcement and manhole, it is characterized in that centrifugal bag is by the molding of two layers of plastic diaphragm high frequency heat seal, article five, flexible pipe directly is fixed between the two-layer diaphragm when centrifugal bag forming, by two sealing strips that are connected with each other with disengagement chamber and collecting chamber seal isolation, form two separate chambers, article one, crank-like sealing strip and a L shaped sealing strip are positioned at disengagement chamber, disengagement chamber is divided into three different zones, another L shaped sealing strip is positioned at collecting chamber, make collecting chamber form two zones, an end of these three sealing strips lays respectively between adjacent several flexible pipes.
The construction features and the operation principle of critical piece of the present utility model are as follows:
This utility model blood constituent separates and collects incorporate centrifugal bag, is to have realized the sealing of disengagement chamber, collecting chamber and at interval by sealing strip.In two chambers, difform sealing strip is arranged, chamber has been divided into different blood constituent race ways, for the blood constituent high efficiency separation provides the structure of optimizing with gathering.There is the flexible pipe that is fixed on the centrifugal bag to communicate with these zones respectively simultaneously, and can be connected, for the transmission of the blood constituent of zones of different provides flow channel with the miscellaneous part of blood component collection utensil.Ellipse hole, manhole and reinforcement match with exocentric structure part on the seperator respectively, and centrifugal bag is played fixation.
Centrifugal bag with said structure, can be connected with blood component separator exocentric structure part by centrifugal bag self structure, by with the cooperating of multi-cavity assembly, utilize the high efficiency fluid principle of dynamics, with blood in disengagement chamber after the high efficiency separation, enter collecting chamber again and realize the efficiently concentrating of blood constituent, thereby reach the isolating optimum efficiency of blood constituent.
Description of drawings
Fig. 1 is the structural representation that this blood constituent separates and collect incorporate centrifugal bag.
The specific embodiment
Embodiment 1
This blood constituent separates and collects incorporate centrifugal bag, is made up of disengagement chamber 1, collecting chamber 2, flexible pipe 3～7, sealing strip 8～12, ellipse hole 13, reinforcement 14 and manhole 15.Centrifugal bag is the molding of two-layer medical polyvinyl diaphragm high frequency heat seal, flexible pipe 3～7 is put between the two-layer diaphragm during molding, directly be fixed on the centrifugal bag, many sealing strips that form during molding, wherein sealing strip 10 is divided into disengagement chamber 1 and collecting chamber 2 with separation bag, and sealing strip 12 is connected two chambers have been realized in the back around centrifugal bag sealing with sealing strip 10.Sealing strip 8 and 9 is positioned at disengagement chamber 1, wherein an end of crank shape sealing strip 9 between flexible pipe 3 and 4, an end of L shaped sealing strip 8 between flexible pipe 4 and 5, make disengagement chamber 1 form three different zones.L shaped sealing strip 11 is positioned at collecting chamber 2, and the one end makes collecting chamber 2 form two zones between flexible pipe 6 and 7.Sealing strip 10 1 ends are between flexible pipe 5 and 6, and the other end links to each other with sealing strip 12.Reinforcement 14 is horizontal two and vertical two, lays respectively at the both sides and the base of centrifugal bag.
