Abstract
The invention relates to a method for sampling plasma acquired from human in a plasma bottle for testing purposes, and in particular relates to a method for acquisition of examination plasma from rigid plasma bottle and belongs to the technical field of medical instruments. A method for acquisition of examination plasma from rigid plasma bottle comprises the following steps: A) lying down the rigid plasma bottle after acquisition, flowing out the plasma from a sampling line, and extracting the plasma through a needle in a shield, wherein a filter plays the roles of aeration liquid separation, and the filtration membrane within the filter can be wetted plasma; and B) inserting an air compression device into the air-vent of the filter, inflating air into the sampling line, so as to return the residue plasma within the sampling line back to the plasma bottle. The device and method provided by the invention allow the residual plasma inside the sampling line back to the plasma bottle, save valuable blood resources, and solve the long-term puzzle and technical problems of hospitals and plasma sampling companies.
Description
Technical field
The present invention relates to check object, the method that the blood plasma in the plasma bottle complete human body collection is sampled, specifically, being the acquisition method of a kind of rigidity plasma bottle inspection blood plasma, belonging to technical field of medical instruments.
Background technology
When Plasma Pheresis/Apheresis Plasma machine gathers blood plasma, filtrated air in separate cup enters in cup along with blood, in cup, air is discharged in plasma bottle, because plasma bottle is solid-state, therefore, air in plasma bottle is discharged outside bottle along with the air strainer of plasma bottle, thus guarantee that blood plasma enters in plasma bottle and do not have resistance, when feeding back, because the red blood cell in separate cup is fed back to human body, air in plasma bottle is got back in separate cup along with plasma tube, negative pressure is produced for preventing plasma bottle, air outside plasma bottle through plasma bottle air strainer supplement enter in plasma bottle.
See Fig. 1, after completing sampled plasma, need to carry out sampling censorship to blood plasma, plasma bottle on Plasma Pheresis/Apheresis Plasma machine takes off by nurse, accumbency is placed on the table, blood plasma in bottle can flow to air strainer by sampling line and haemocyte samples puncture outfit place, object is first got rid of (now by the air in sampling line 6, the air strainer film of filtrator 2 may be dampened), then plasma sample is left and taken by the haemocyte sampling puncture outfit of plasma bottle, after stopple coupon inserts haemocyte sampling puncture outfit, blood plasma in bottle enters stopple coupon along with haemocyte samples puncture outfit.In this process, because the air strainer film of filtrator 2 may be sticky wet by blood plasma, so after sampling completes, residual plasma in sampling line 6 cannot flow back in plasma bottle 1, cause the waste of this section of blood plasma, hospital and blood collecting company sampled plasma use amount very huge, take care of the pence, this wasting phenomenon brings very large puzzlement to hospital and blood collecting company.
The solution of prior art concentrates on the filter densities performance of the air-filtering membrane 202 on research filtrator 2, if but filter densities is too low, then can there is the phenomenon of plasma lipid in the leakage of air strainer place, filter densities is too high, then there will be poor air permeability, be vented not smooth phenomenon, so the air-filtering membrane will developing the appropriate filter density performance that can solve this technical matters is a very difficult thing.
Summary of the invention
The technical issues that need to address of the present invention are: in the gatherer process of rigidity plasma bottle inspection blood plasma, after sampling completes, residual plasma in sampling line cannot flow back in plasma bottle, causes the waste of this section of blood plasma, and this wasting phenomenon brings very large puzzlement to hospital and blood collecting company.
The present invention takes following technical scheme:
An acquisition method for rigidity plasma bottle inspection blood plasma, is characterized in that, comprise the following steps:
A) will complete the rigidity plasma bottle accumbency of blood sampling, blood plasma flows out from sampling line 6, and the needle tubing 401 in protective cover 4 is extracted out; Filtrator 2 plays ventilation every liquid, and the filtering membrane 202 in it may be sticky wet by blood plasma;
B) adopt air compression plant to insert the blow vent of filtrator 2, in sampling line 6, be filled with air, the residual plasma in sampling line 6 is got back in plasma bottle.
Further, steps A) existing that plasma bottle is upright afterwards, then implementation step B).
A harvester for above-mentioned acquisition method, is characterized in that: comprise air compression plant, filtrator 2, and the gas outlet of described air compression plant coordinates with the vents seal of described filtrator 2.
Further, described air compression plant is injection needle tube.
Further, described air compression plant is sphygmomanometer ball.
Further, described air compression plant is inflator pump.
Beneficial effect of the present invention is:
1) residual plasma in sampling line can be made to get back in plasma bottle, save valuable blood resource.
2) puzzlement for a long time of hospital and blood collecting company and technical barrier is solved.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
An acquisition method for rigidity plasma bottle inspection blood plasma, comprises the following steps:
A) will complete the rigidity plasma bottle accumbency of blood sampling, blood plasma flows out from sampling line 6, and the needle tubing 401 in protective cover 4 is extracted out; Filtrator 2 plays ventilation every liquid, and the filtering membrane 202 in it may be sticky wet by blood plasma; Plasma bottle is upright;
B) adopt air compression plant to insert the blow vent of filtrator 2, in sampling line, be filled with air, the residual plasma in sampling line is got back in plasma bottle.
