Description
Technical Field
The invention relates to the technical field of umbilical cord blood sampling articles, in particular to a special umbilical cord blood sampling bag and umbilical cord blood sampling equipment.
Background
Umbilical cord blood is venous blood remaining in a placenta and an umbilical cord after a fetus is delivered and the umbilical cord is broken, is rich in stem cells, and is an important source of stem cells except bone marrow and peripheral blood. Umbilical cord blood is widely used clinically in the treatment of various blood diseases, hereditary and congenital diseases.
After the umbilical cord is broken, the umbilical cord blood in the placenta coagulates blood in a few minutes, and the optimal collection time of the umbilical cord blood is 1-2 minutes after the umbilical cord is broken. At present generally use venous blood collection bag to gather umbilical cord blood, the foetus is delivered to the navel to after breaking off, go into the umbilical vein with the blood taking needle puncture behind the disinfection umbilical cord, put the blood bag low, utilize the difference in height of placenta and blood collection bag, make umbilical cord blood flow income blood collection bag, concrete operating procedure is as follows:
preparing a blood collection bag: removing the blood bag, packaging, checking blood stasis, unscrewing the needle head, and preparing a disinfection bag;
disinfecting and puncturing: disinfecting an umbilical cord, disinfecting a puncture point by iodophor, and puncturing a blood taking needle into an umbilical vein;
collecting umbilical cord blood: fixing the blood taking needle by hands or hemostatic forceps, lowering the blood bag to have a height difference with the placenta, and continuously mixing the blood bag uniformly in the collection process;
and (5) finishing collection: when the umbilical cord is grey and sunken and no blood flows out, the blood stop is closed and the needle head is retracted.
The prior art has the following problems:
the collection amount is small: after the umbilical cord is broken, the umbilical cord blood coagulates in a few minutes, the time for collecting the umbilical cord blood is short, the umbilical cord blood can only flow downwards by gravity, the collecting flow rate is slow, the umbilical cord blood is not completely coagulated in the placenta, the collecting amount is small, and a large amount of umbilical cord blood is wasted in the placenta.
Mixing with the coagulum: in the later period of collection, the umbilical cord blood in the placenta and the umbilical cord begins to coagulate blood, and the small coagulated blood can enter a blood bag through the needle head, so that the subsequent detection and use are influenced.
