Compared with the prior art, the special negative pressure blood drawing component for children, which adopts the technical scheme, has the following beneficial effects:
one, adopt the utility model discloses a subassembly is taken out to special negative pressure of children does not need to change the vacuum test tube and collects the blood sample when taking out the blood, and accessible negative pressure container once takes out the blood that needs the extraction, presss from both sides through only flowing and carry blood to vacuum test tube after taking out the blood and taking a blood sample, the difficult step of operation when reducing the infusion, makes the nurse can put attention on controlling children puncture department condition, avoids because children move about etc. make the venous test needle deviate from.
And the negative pressure container is made of transparent material and is provided with scales, so that the blood volume extracted by the negative pressure container can meet the requirement through observation and confirmation, and more pain of children caused by multiple blood sampling is avoided.
Third, because medical supplies's recovery needs classify, can conveniently separate first pipe and second pipe and negative pressure test tube through the lid, conveniently classify and retrieve them, and the structure of lid and negative pressure test tube is similar vacuum blood collection tube, when processing the preparation, can take and make the same mode with preparation vacuum blood collection tube and process, has the feasibility.
The negative pressure test tube is large in size, the operation of the flow stopping clamp is easily influenced by the displacement of the negative pressure test tube during blood sampling, the limiting structure can fix the negative pressure test tube during blood sampling, so that a nurse cannot conveniently control blood sampling through the flow stopping clamp due to the fact that the first guide tube and the second guide tube are driven to move by the movement of the negative pressure test tube during operation, and damage to children due to misoperation is avoided; when the vacuum blood collection tube draws blood from the negative pressure test tube, the sucking disc is attached in the bottom of negative pressure test tube, and the negative pressure test tube is vertical to be fixed on the desktop, need not the nurse and grips, makes things convenient for the vacuum blood collection tube to draw blood from the negative pressure test tube through the second pipe.
Fifthly, first butt joint can dismantle with the blood taking needle and be connected, and after finishing using, can dismantle the blood taking needle and put into the edge tool box, avoid because a blood taking needle, and make negative pressure test tube, first pipe and second pipe etc. all deposit in the edge tool box, categorised unreasonable.
Sixth, the second is to connecting can dismantle with the bloodletting head and be connected, after the use, can be to the categorised recovery of bloodletting head, and the second is to connecting also can be connected with the cylinder simultaneously, and the blood sample is used in the inspection that need not use the vacuum test tube collection such as collection blood gas analysis.
And the anticoagulant can prevent blood from coagulating, so that the blood coagulation influences the extraction effect when the blood is collected by the vacuum blood collection tube or the needle cylinder, and even the second catheter is blocked.
