Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a disposable breathable blood sampling container.
Background
There are generally two technical routes to clinically collect Platelet Rich (PRP):
1. disposable vacuum blood collection tube and separating gel.
The application method is that the disposable blood taking needle is matched to draw a human body vein blood sample, after one-time centrifugation, a needle capable of ventilating is inserted from the top end, a long needle is inserted, waste plasma above the needle is firstly drawn, and then useful PRP is drawn.
The main problems are three:
firstly, if the inserted needle has no bacterium blocking function and is directly communicated with the atmosphere, the possibility of pollution exists;
secondly, the rubber plugs above the blood sampling tubes are not special rubber plugs which can be punctured repeatedly, so that the puncturing performance is poor, and particle pollution can be caused;
thirdly, the long needle is difficult to control the direction during puncture, and good products which are well centrifuged can be damaged in the repeated fitting process, so that the preparation effect is influenced.
2. Disposable PRP preparation suit
The using method comprises the steps of firstly using a syringe to collect blood, then opening the centrifuge tube from the upper part to inject the blood sample, sealing the centrifuge tube with a disposable bacteria-blocking bag after sealing the centrifuge tube, performing centrifugation for one time or two times, replacing the bacteria-blocking bag after each centrifugation, opening a cap or an adhesive tape on the centrifuge tube, and extracting waste plasma and useful PRP (platelet-plasma) by using a long needle.
The main problems are three:
1. in such a preparation mode, the centrifugal tube needs to be opened for many times, so that the risk of bacterial contamination of blood exists;
2. the operation of drawing with a long needle is very inconvenient;
3. the use of the bacteria-stopping sleeve in the centrifugation process is very unsafe.
Therefore, there is a need for an improved centrifuge tube, and for this purpose we propose a permeable disposable air-permeable blood collection container to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a ventilative formula blood sampling container of disposable to solve the problem that proposes in the above-mentioned background art.
The technical scheme of the utility model is that: the utility model provides a ventilative formula blood sampling container of disposable, includes blood sampling container body, its characterized in that: the disposable blood sampling container is characterized in that a high-separation cover is arranged at one end of the blood sampling container body, a breathable waterproof membrane is arranged at one end of the blood sampling container body, the high-separation cover is hermetically connected with one end of the blood sampling container body, and a pierceable rubber plug is arranged at the other end of the blood sampling container body.
Or the high-barrier cover is replaced by a cover body fixedly connected with the breathable waterproof membrane, and the cover body is additionally provided with an air passage and an opening and closing cap.
Preferably, the high-barrier cover is in threaded connection or sleeved connection with the surface of the blood sampling container body, and the high-barrier cover is detachably mounted on the blood sampling container body.
The utility model discloses an improve and provide a ventilative formula blood sampling container of disposable here and compare with prior art, have following improvement and advantage:
one is as follows: the utility model can directly extract the needed blood products and reduce the production of long needles by arranging the rubber plug which can be punctured repeatedly at one end (the lower end during centrifugation) of the blood sampling container;
the second step is as follows: the high-barrier cover is matched with the breathable waterproof membrane, so that the pressure in the blood sampling container body can be adjusted, and blood is sealed in the blood sampling container body, so that secondary pollution is prevented;
and thirdly: the damage of the separation glue to the human body can be avoided.
