Abstract
The utility model discloses a plasma-separating bag used with a blood-separating machine together compatibly, which is mainly used for separating ingredients of the blood of from a donor. The utility model consists of an airtight bag body, an inlet for whole blood, an outlet for plasma with poor ingredients and an outlet for plasma with rich ingredients. The inner space of the bag body is divided into an upper cavity body and a lower cavity body by an L-shaped thermosynthesis isolating line and one end of the two cavity bodies is intercommunicated while the other end is isolated. The outlet for plasma with rich ingredients is positioned on the end of the lower cavity body, that is, at the end of the flowing route of the plasma with rich ingredients. The inlet for whole blood and the outlet for plasma with poor ingredients are positioned on the upper end of the upper cavity body. The L-shaped thermosynthesis isolating line in the utility model divides the inner space of the bag body into an upper cavity body and a lower cavity body. The structure can effectively separate the plasma with poor ingredients from the plasma with rich ingredients and the structure is thus made more simple and compact. In addition, the utility model changes the prior mode of twice separations and accomplishes the blood separation at one time, thereby shortening the separating time greatly.
Description
Technical field
This utility model relates to a kind of disposable medical consumption apparatus, and the specifically a kind of and matching used blood plasma separation bag of blood separator is mainly used in separated plasma composition from blood donor's blood.
Background technology
At present, the method of traditional collection blood plasma is with separating cup type collection, generally form with the matching used blood plasma separation bag of blood separator by separation bag and collecting bag two parts, wherein separation bag comprises bag, the whole blood inlet, plasma fraction (poor composition) outlet that the plasma fraction that density is bigger (rich composition) outlet and density are less, be that blood centrifugalize in separation bag is gone out the bigger composition of density, it mainly is erythrocyte, again these heavy compositions are collected in the collecting bag, carry out the centrifugalize second time, the less poor blood plasma of isolated once more density withdraws from the collecting bag composition merging less with the density of separating for the first time in separation bag, be defeated by human body.This separate mode complexity, acquisition time is longer, in addition, the blood of human body composition compares permutatation according to it, be respectively erythrocyte, leukocyte, lymphocyte, platelet and blood plasma, only can import its desirable ingredients as required in the medical treatment to patient, such as, separating plasma need only be come out be defeated by patient, remainder is fed back to the blood donor, and is so more scientific and reasonable, both looked after patient's needs, having guaranteed the healthy of blood donor again to greatest extent, is a kind of saving to blood medicine source.But, regrettably, all do not adopt this scheme in the prior art, such as, in the Chinese patent 200420082755.2 and 200420039692.2, all do not solve the disposable problem of isolating utility, the isolating construction complexity, it is long to separate required time.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and provides a kind of and the matching used blood plasma separation bag of blood separator, it can carry out disposable separation to blood, isolate blood plasma and feedback blood donor's rich composition blood plasma, and simple and compact for structure.
The purpose of this utility model is achieved in that
Disposable use blood plasma separation bag, comprise airtight bag, whole blood inlet, poor composition blood plasma outlet, the outlet of rich composition blood plasma, in bag, the bag inner space is divided into upper and lower two cavitys by one " L " type thermal synthesis shielding wire, upper and lower two cavity one ends are communicated with, the other end is isolated, rich composition blood plasma outlet is positioned at the lower chamber end, the rearmost end of promptly rich composition blood plasma glide path, and whole blood inlet and poor composition blood plasma outlet are positioned at the upper end of upper cavity.
In order to improve separating effect, as improvement of the present utility model, between whole blood inlet and poor composition blood plasma outlet, also be provided with a guide pad, be mainly used in the glide path that enters the blood in the separation bag and lead, make it present " L " type glide path.
Operation principle of the present utility model is as follows:
Enter the upper cavity of separation bag when whole blood after, the blood constituent of greater density mainly is erythrocyte, leukocyte, platelet, under action of centrifugal force, to the outside of separation bag hematocrit, is sink in the lower chamber, withdraws from separation bag by rich composition blood plasma outlet then; And the less composition of density mainly is a blood plasma, withdraws from separation bag by poor composition blood plasma outlet.
This utility model has following advantage than prior art:
Because this utility model is divided into upper and lower two cavitys by one " L " type thermal synthesis shielding wire with the bag inner space in bag, this isolating construction has substituted original two bags of isolating constructions, can well poor, rich composition blood plasma be separated effectively, structure is simple more compact; In addition, it has changed original twice separate mode, make disposable being accomplished of separation of blood, shortened disengaging time widely, separating plasma is come out, remainder is fed back to the blood donor, more scientific and reasonable, both isolated blood plasma effectively, guaranteed the healthy of blood donor again to greatest extent, blood medicine source has been accomplished to save to greatest extent.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that adopts plasma separator of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As can be known from Fig. 1, disposable use blood plasma separation bag, comprise airtight bag 1, whole blood inlet 2, poor composition blood plasma outlet 3, rich composition blood plasma outlet 4, in bag, the bag inner space is divided into upper and lower two cavitys 6 and 7 by one " L " type thermal synthesis shielding wire 5, upper cavity 6, lower chamber 7 one ends are communicated with, the other end is isolated, rich composition blood plasma outlet 4 is positioned at lower chamber 7 ends, be the rearmost end of rich composition blood plasma glide path, whole blood inlet 2 and poor composition blood plasma outlet 3 are positioned at the upper end of upper cavity 6.
In order to improve separating effect, as improvement of the present utility model, between whole blood inlet 2 and poor composition blood plasma outlet 3, also be provided with a guide pad 8, be mainly used in the glide path that enters the blood in the separation bag and lead, make it present " L " type glide path.
