Description

The blood cell separator of disposable use pocket type

Technical field

This utility model relates to a kind of separator of collecting blood component, and particularly a kind of is that carrier carries out the medical consumption utensil of the isolating disposable use of centrifugal blood formula with soft bag.

Background technology

At present, human body is donated blood and is still the main source of medicinal blood.When donating blood, often only need certain or certain several specific blood component, for example blood plasma, platelet, erythrocyte or leukocyte etc., and other compositions can feed back to the blood donor, to avoid the waste of blood resource.Therefore, donate blood technology in the modern times, adopt blood component to gather isolating method 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, then remaining composition blood is fed back to the blood donor.

At present, there has been the blood that to gather blood component to be separated by blood separator, but cooperate the medical disposable material of seperator very different, not taking of having is totally-enclosed, what have does not have a supervising device, the separation bag unreasonable structure that has does not also have a kind of and the supporting use of blood component seperator at present, can carry out efficiently separating automatically, collection efficiency is higher, the blood donor is fed back safe disposable use blood component separator.

Summary of the invention

Present situation in view of above-mentioned blood component separator, the purpose of this utility model provides a kind of and the supporting use of blood component seperator, and the blood donor is fed back safety, can carry out efficient separation, the higher disposable blood component separator of collection efficiency automatically to the blood component of being gathered.

The disposable use pocket type blood cell separator that this utility model provides can realize above-mentioned purpose.This utility model comprises hemostix, also defeated filter, the whole blood bag, plasma bags, the erythrocyte bag, the product stock bag, supervising device, separation bag, multi-lumen tube and gas trap, it is characterized in that supervising device is three identical in structure devices, hemostix by connection tube respectively with first perforator, also defeated filter, first supervising device links to each other with second supervising device, first supervising device by connection tube respectively with defeated filter also, the whole blood bag, the erythrocyte bag links to each other with the gas trap, second supervising device by connection tube respectively with second perforator, the 3rd supervising device, plasma bags links to each other with multi-lumen tube, the 3rd supervising device by connection tube respectively with the product stock bag, the gas trap links to each other with multi-lumen tube, and multi-lumen tube links to each other with separation bag by connection tube.

The construction features and the operation principle of critical piece of the present utility model are as follows:

Supervising device: form by 10 valves, 4 pressure sensing contact points with corresponding to the input and output joint of valve and pressure sensing contact point respectively, cooperate with valve on the supervising device by the piston on the blood component seperator, realize opening or closing of liquid line, reach the automatic control of liquid stream direction.The pressure sensing contact point is positioned at the two ends of supervising device box body, malleation and negative pressure in measurement and the monitored pipeline.Each supervising device is measured the pressure of corresponding monitored pipeline by these four diverse locations, according to the switch of the different conditions control respective valves of each loine pressure.

Separation bag: be the soft bag of forming by two mutual disconnected space disengagement chambers and collecting chamber by the centrifugal storehouse of seperator optimal design.Self structure by bag is fixed on the rotating cylinder of blood component seperator, cooperation by multi-lumen tube, utilize the high efficiency fluid principle of dynamics, under the driving force of blood component seperator rotating cylinder, in disengagement chamber, the anticoagulant separation of whole blood is become packed red cells, leukocyte and platelet rich plasma, realize the efficiently concentrating of products of separated again by collecting chamber, thereby realize the isolating optimum efficiency of blood component.

Multi-lumen tube: fixed bearing, top connection and lower contact are assemblied in it on blood component seperator on it, so that cooperate with separation bag, realize reversing the reconciliation twisting action by bearing by the rotating cylinder of blood component seperator and two kinds of different rotation rates initiations of rotating cylinder bracket, thereby cooperate the blood component seperator to realize that the connected sum of separation bag and pipeline drives the high speed rotating of separation bag, to finish the optimization of separation process, improved collection efficiency.

This utility model has this disposable use pocket type blood cell separator and can carry out efficient separation, the higher remarkable advantage of collection efficiency automatically to the blood component of being gathered owing to adopted supervising device, separation bag and the multi-lumen tube with said structure novelty, complete function.Simultaneously,, therefore, can reduce cross infection to greatest extent, protection blood donor's health owing to adopt sealed self-circulation system.
