Description
[technical field]
This utility model relates to the blood sampling of a kind of infant, infusion set.
[background technology]
Continuous development along with modern medicine, lab testing has been one of indispensable important inspection method of diagnose and treat diseases, lab testing correctness as a result directly influences diagnosis, treatment and the rescue work of disease, how to guarantee that effective collecting blood sample becomes a great problem of pediatric nursing.Because the infant blood vessel is more tiny, concealment, the limb vessel depth is not surveyed, should not touch, puncture is once success often, suction time and be the generation that the tourniquet time lengthening also tends to cause mechanicalness haemolysis and blood coagulation, for reducing the infant misery, should be the scalp vein blood sampling to the infant first-selection.The method of infant scalp blood sampling at present adopts the scalp acupuncture venipuncture more, syringe pump, but infant is mismatched more first, cause suction failure or hematoma to form easily,, often cause blood volume not meet standard again second with the blood taking tube that reinjects behind the blood collection needle, influence the accuracy of lab testing, three then need the syringe dispensing as needing many parts of inspection blood, have increased the probability of sample contamination.Also have a kind of mode of taking a blood sample to be to use adult's scalp formula blood taking needle clinically at present, but, do not meet infant venous anatomy characteristics, strengthened the difficulty of puncture, cause iatrogenic injury easily because syringe needle is not only thick but also long.And, the venous blood collection of department of pediatrics clinical practice and venous transfusion adopt the operation of two steps to carry out usually, be to extract piercing needle behind the venous blood collection, change the position, venous transfusion is carried out in puncture more again, repeated localised puncture not only can be incured loss through delay rescue opportunity when rescuing critical infant like this, simultaneously, also can destroy blood vessel, increase the infant and the head of a family's misery.
[summary of the invention]
The purpose of this utility model is to provide the dual-purpose scalp formula of a kind of infant two-way blood taking needle, and the infant that carries out that it not only can be convenient and safe is taken a blood sample, and also can save time for rescuing critical patient simultaneously, and the protection blood vessel palliates the agonizing sufferings.
The purpose of this utility model realizes by the following technical solutions:
The two-way blood taking needle of the dual-purpose scalp formula of a kind of infant is characterized in that, it comprises scalp piercing needle 1, fixed-wing 2, connects flexible pipe 3, three way cock 4, threeway pathway control valve 5, blood taking needle 6, vacuum test tube 7, filter for transfusion 8; Three ports of three way cock 4 are connected respectively at scalp piercing needle 1, blood taking needle 6, filter for transfusion 8 by connecting flexible pipe 3; Threeway pathway control valve 5 is installed on the three way cock 4, scalp puncture needle 1 pipeline communicates with blood taking needle 6 pipelines during the I phase place, scalp puncture needle 1 pipeline communicates with filter for transfusion 8 pipelines during the II phase place, and filter for transfusion 8 pipelines communicate with blood taking needle 6 pipelines during the III phase place; Blood taking needle 6 ends are sealed rubber cover parcel.
Described scalp piercing needle 1 can adopt syringe needle 5～No. 7.
The beneficial effects of the utility model are:
1, aseptic degree height, the blood contamination probability is little, and is little to the interference of assay.
2, directly blood is injected blood taking tube, avoided that syringe injects the change that causes blood formed element in the blood taking tube, the haemolysis due to the hematoclasis with blood in the traditional method, assay is more true and reliable.Simultaneously, preset various additives in the blood taking tube, can satisfy clinical multinomial comprehensive blood testing fully.
3, vacuum test tube has preset a certain amount of negative pressure in process of production, and behind blood taking needle puncture intravasation, because the suction function in the blood taking tube, blood flows in the blood taking tube automatically, and blood sampling volume is accurate.
4, this scalp pin type blood taking needle needle point to be taken a blood sample advances visible blood-flow behind the blood vessel, and is therefore less demanding to operator's puncture technique, improves puncture success rate.
5, blood sampling can be finished synchronously with venous transfusion.Avoid the patient when venous transfusion and blood sampling the time need carry out twice puncture, thereby alleviated patient's misery.Also reduced staff's workload, time saving and energy saving, improved work efficiency.
[description of drawings]
Fig. 1 uses sketch map for this utility model embodiment.
[specific embodiment]
Below in conjunction with specification drawings and specific embodiments this utility model is further specified.
Be use sketch map of the present utility model as shown in Figure 1, the two-way blood taking needle of the dual-purpose scalp formula of infant comprises scalp piercing needle 1, fixed-wing 2, connects flexible pipe 3, three way cock 4, threeway pathway control valve 5, blood taking needle 6, vacuum test tube 7, filter for transfusion 8; Three ports of three way cock 4 are connected respectively at scalp piercing needle 1, blood taking needle 6, filter for transfusion 8 by connecting flexible pipe 3, and threeway pathway control valve 5 is installed on the three way cock 4.During the I phase place, threeway pathway control valve 5 is positioned on 51 the position, and scalp puncture needle 1 pipeline communicates with blood taking needle 6 pipelines; During the II phase place, threeway pathway control valve 5 is positioned on 52 the position, and scalp puncture needle 1 pipeline communicates with filter for transfusion 8 pipelines; During the III phase place, threeway pathway control valve 5 is positioned on 53 the position, and filter for transfusion 8 pipelines communicate with blood taking needle 6 pipelines, and blood taking needle 6 is terminal to be wrapped up for the sealed rubber cover.According to the physiological characteristics of infant, it is best that scalp piercing needle 1 adopts 5～No. 7 syringe needles.
During clinical manipulation, it is stand-by earlier threeway pathway control valve 5 to be adjusted to the I phase place, and this moment, scalp puncture needle 1 pipeline communicated with blood taking needle 6 pipelines.Select blood vessel then, routine disinfection skin, scalp puncture needle 1 one ends such as venous transfusion puncture sample are thrust vein, after seeing blood back, with the fixing fixed-wing 2 of infusion patch, blood taking needle 6 one ends are thrust vacuum test tube 7 since vacuum test tube 7 prefabricated vacuum capacity accurately, automatically blood is sucked test tube during blood sampling, avoided artificial suction.
As only being when operation blood sampling, after blood sampling finishes, extract scalp piercing needle 1 earlier, wait to bleed and extract vacuum test tube 7 end blood taking needles 6 again after stopping.
Further carry out venous transfusion as clinical needs by this venous channel, after then blood sampling finishes, earlier threeway pathway control valve 5 is adjusted to the III phase place, filter for transfusion 8 pipelines communicate with blood taking needle 6 pipelines, transfusion device 9 aerofluxuss, and wash down the micro blood that remains in the blood collection needles, cover blood taking needle cap.Again threeway pathway control valve 5 is adjusted to the II phase place, scalp puncture needle 1 pipeline communicates with filter for transfusion 8 pipelines, can begin transfusion.
Need to prove; particular of the present utility model is described in detail this utility model; for a person skilled in the art, in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out all within protection domain of the present utility model.
