Problems solved by technology
The collector needs to be sterilized before use, but the disinfection process will cause some damage to the liquid anticoagulant
On the other hand, manual addition of anticoagulant will bring a certain risk of contamination, and in the actual operation of the hospital because the environment of the delivery room is not always very clean. Therefore, it is necessary to use convenient and feasible pre-sterile equipment, materials and aseptic technique for cord blood collection
In addition, adding too much or too little anticoagulant, or the failure of the anticoagulant itself will cause blood coagulation, thereby reducing the practical value of cord blood
Experiments have further proved that the use of liquid anticoagulants will also lead to a decrease in the recovery rate of cord blood cells due to changes in cell osmotic pressure

Embodiment
[0034] The collection box for collecting umbilical cord blood includes a collection box, in which a sterile container for collecting umbilical cord blood is arranged, and a sufficient amount of non-liquid anticoagulant is arranged in the container for collecting umbilical cord blood.
[0035] In this embodiment, the container for collecting umbilical cord blood is a syringe or a collection bag. Syringes or collection bags are two different collection instruments, and the different usage methods of the two collection instruments will be given below.
[0036] In order to ensure the anticoagulant effect, the non-liquid anticoagulant includes heparin, heparan-like additives, citrate, ethylenediaminetetraacetic acid and oxalic acid, and the non-liquid anticoagulant is freeze-dried or powdered.
[0037] In addition, one or more of sterile wipes, syringes, trays, identification labels, instructions for use, gauze, and needle holders are also arranged in the sterile box.

The invention discloses a collecting box for collecting cord blood and a use method of the collecting box. The collecting box comprises a collecting box, wherein a container for aseptically collecting cord blood is arranged in the box; and a sufficient non-liquid anticoagulant is filled in the container for collecting cord blood, and more specifically, the container for collecting cord blood is an injector or a collecting bag; the non-liquid anticoagulant comprises heparin, heparinoid type additives, citrate, ethylene diamine tetraacetic acid and oxalic acid. The invention also provides the use method of the collecting box for collecting cord blood. The use method comprises the following steps of: a, checking and disinfecting; b, checking the container; c, starting to collect; d, collecting a blood sample; e, repeatedly collecting; and f, mixing. All appliances and parts of the collecting box can be produced in batch, assembled and disinfected; the collecting box is good in stability, convenient to use and low in cost, and a human error of quantitative use of the anticoagulant can be eliminated; and meanwhile, the use method provided by the invention is simple to operate and a large amount of training time is saved.
Description
technical field [0001] The present invention relates to a collection box for collecting umbilical cord blood and a method of use thereof. Background technique [0002] Umbilical cord blood is the blood that remains in the umbilical cord or placental tissue of a newborn after the umbilical cord is cut. Normally, the umbilical cord is discarded as biological waste along with the placenta after the baby is born. Cord blood contains stem cells of high medical value, such as hematopoietic stem cells, which can be used in many different stem cell transplants and regenerative medicine applications, such as hematopoietic stem cell transplantation for the treatment of blood cell deficiency diseases and tumor diseases. Therefore, as an important source of stem cells and other mononuclear cells, infant umbilical cord blood, collecting and preserving these stem cells provides the necessary guarantee for future clinical application. [0003] Human hematopoietic stem cells are the mothe...
