Description
Technical field
This utility model relates to a kind of blood-taking device, relates in particular to a kind of blood taking bag for gathering Cord blood, and described blood taking bag comprises blood taking needle and storage blood bag, and described blood taking needle and storage blood bag are communicated with by conduit.
Background technology
Find through medical practice and research, can save cases with leukemia child's life with neonatal Cord blood.The acquisition step of Cord blood is not finished in blood bank, but the hospital of delivering a child that entrusts the puerpera to live is responsible for collection.After neonate is cut off umbilical cord, medical personnel will extract Cord blood out and deposit storage blood bag in blood taking needle from umbilical cord and Placenta Hominis.Cord blood need to carry out heavy detection to Cord blood before warehouse-in, comprise cell quantity detection, the pathogenic microorganism examination (immunology detection), antibacterial culturing, stem cell content and active the detection.The first blood taking bag of the prior art comprises blood taking needle and storage blood bag, and described blood taking needle and storage blood bag are communicated with by long conduit (being generally about 1 meter).Such blood taking bag is applicable to the blood sampling to the blood donor.The blood donor needs blood count before donating blood, after blood matter is qualified, take a blood sample with blood taking bag again.Also have the second blood taking bag in the prior art, this blood taking bag is above-mentioned the first blood taking bag to be communicated with by threeway and sampler near near the conduit the blood taking needle consist of.It can carry out sampling operation in blood sampling.But the puerpera is before childbirth, and medical personnel can't sample and detect baby's Cord blood.The puerpera is in childbirth, and medical personnel can gather Cord blood by blood taking needle in time and deposit storage blood bag in from umbilical cord and Placenta Hominis, and still, inconvenience is sampled to Cord blood when gathering Cord blood and detected.Sampling and detection to Cord blood can only after the work that gathers Cord blood be finished, be taken out blood sample and detect from storage blood bag.Yet, use above-mentioned the first blood taking bag to gather Cord blood, after blood sampling work is finished, first the heat seal sealing is carried out in the conduit of blood taking bag, and blood taking bag is delivered to blood bank, when sampling, heat seal sealing cut off carry out sampling operation, like this, blood sample is contacted with extraneous the generation, be difficult to guarantee the not contaminated or not infected antibacterial of blood sample.The blood taking bag that uses above-mentioned the second to have sampler gathers Cord blood, after blood sampling work is finished, also need first the conduit of blood taking bag is carried out the heat seal sealing, the position of its heat seal sealing can only be near the conduit the close blood taking needle, that is to say, catheter length between sampler and the storage blood bag is longer, blood taking bag is delivered to blood bank, when sampling, because the catheter length between sampler and the storage blood bag is longer, the long conduit resistance that circulation produces to Cord blood is very big, so, only depend on the very difficult Cord blood that will store up in the blood bag of negative pressure of sampler to suck sampler, if by extruding storage blood bag Cord blood is clamp-oned the activity that sampler will affect Cord blood; And, after sampling, the Cord blood that remains in the conduit should not be turned back in the storage blood bag to guarantee to store up the quality of Cord blood in the blood bag.Will cause like this waste of Cord blood.This shows, conduit is longer, and the Cord blood of waste is more.
The utility model content
The technical problems to be solved in the utility model provides a kind of blood taking bag for gathering Cord blood.In the process of sampling, will store up at an easy rate the Cord blood sucking-off in the blood bag, simultaneously, the Cord blood of waste greatly reduces, and guarantees not contaminated, the not infected antibacterial of blood sample, is conducive to draw correct testing result.
In order to solve the problems of the technologies described above, a kind of blood taking bag for gathering Cord blood that this utility model provides, comprise blood taking needle and storage blood bag, described blood taking needle and storage blood bag are communicated with by conduit, described conduit is provided with a threeway near an end of described storage blood bag, the two ends of described threeway are communicated with described conduit, and an other end of described threeway is connected with hemostix by easy folding plug and conduit.
An other end of described threeway is communicated with the entrance of described easy folding plug by the other end that easy folding plug and conduit are connected with hemostix for described threeway, the outlet of described easy folding plug is communicated with an end of described conduit, and the other end of described conduit is communicated with the entrance of described hemostix; Perhaps, an other end of described threeway is communicated with an end of described conduit by the other end that easy folding plug and conduit are connected with hemostix for described threeway, the other end of described conduit is communicated with the entrance of described easy folding plug, and the outlet of described easy folding plug is communicated with the entrance of described hemostix; Perhaps, described conduit is divided into dummy pipe and rear tube, an other end of described threeway is communicated with an end of described dummy pipe by the other end that easy folding plug and conduit are connected with hemostix for described threeway, the other end of described dummy pipe is communicated with the entrance of described easy folding plug, the outlet of described easy folding plug is communicated with an end of described rear tube, and the other end of described rear tube is communicated with the entrance of described hemostix.
Catheter length between described blood taking needle and the described threeway is 75cm; Catheter length between described threeway and the described storage blood bag is 20cm; Catheter length between described threeway and the described hemostix is 5cm.
Conduit between described blood taking needle and the described threeway is provided with blood to be ended; Conduit between described threeway and the described hemostix is provided with blood to be ended.
Described blood taking needle is provided with protective sleeve.
This utility model has following beneficial effect with respect to prior art:
