Description
Technical field
The utility model belongs to technical field of medical instrument more particularly to a kind of double-end blood transfusion apparatus.
Background technique
In hospital clinical work, often there is patient to need to transfuse blood, and more than defeated one bag of blood.Two during blood transfusion
It needs to be separated with physiological saline between bag blood, this is that two bags of blood that blood source is different in order to prevent play Coagulation test.Existing single tube
Transfusion set, only one puncture needle of the top of perfusion tube, it is necessary to which plug puncture outfit is back and forth to be respectively connected to normal saline bag
Or blood bag, this not only operates very cumbersome, but also is not avoided that remained blood enters physiological saline, and it is anti-to may cause blood coagulation
It answers.In order to avoid the generation of above situation, Y shape transfusion set is usually used in blood transfusion now, and Y shape transfusion set includes two punctures
Needle, two puncture needles are respectively connected to normal saline bag and blood bag, say that blood transfusion tube is connected to perfusion tube using medical connection wye.But
It is the sticky larger of blood, therefore in transfusion procedure, blood all can be inevitably remained in blood bag and blood transfusion tube, thus can
Cause the waste of blood；Simultaneously because remain blood in blood transfusion tube, when puncture needle of transfusing blood is inserted into the transfusion bags in another blood source,
The blood in different blood sources can be made to mix in blood transfusion tube, may cause Coagulation test.
Utility model content
Avoid double end that Coagulation test occurs and that blood utilization rate is high defeated the purpose of this utility model is to provide a kind of
Blood device.
In order to achieve the above object, the base case of the utility model are as follows: a kind of double-end blood transfusion apparatus, including blood transfusion portion and defeated
Liquid portion, blood transfusion portion include blood transfusion tube and blood transfusion puncture needle, and infusion portion includes perfusion tube and body-free transfusion puncture needle, blood transfusion tube and perfusion tube
Separate blood transfusion puncture needle one end between be communicated with three-way connection, be also communicated with conduit on three-way connection, end of conduit connection
There is venipuncture needle, be equipped with flow-stopping clip on blood transfusion tube and perfusion tube, return pipe is communicated between delivery pipe and perfusion tube, flows back
Pipe is located at side of the flow-stopping clip far from three-way connection, is also equipped with flow-stopping clip on return pipe.
The working principle and beneficial effect of this base case are: fluid stopping when blood transfusion, on closing volume pipe and perfusion tube
Folder, opens the flow-stopping clip on blood transfusion tube, and blood flows to venipuncture needle from blood transfusion tube, transfuses blood；After the completion of blood transfusion, close defeated
Flow-stopping clip on blood vessel opens the flow-stopping clip on return pipe, and physiological saline flows through return pipe, blood transfusion tube top from perfusion tube, most
It flows into transfusion bags afterwards, clears up physiological saline to blood remaining in transfusion bags, avoid waste, improve blood
Utilization rate；When infusion, all flow-stopping clips are opened, pass through physiological saline in perfusion tube and blood transfusion tube inflow catheter, then pass through
Venipuncture needle flows into human body, can clear up blood remaining in blood transfusion tube when physiological saline flows through blood transfusion tube, remove
Blood in net blood transfusion tube avoids that Coagulation test occurs when replacement blood bag blood transfusion, while also improving the utilization rate of blood.
Further, chemical feed pipe is communicated on the perfusion tube, chemical feed pipe has rubber cock body far from the closed at one end of perfusion tube,
Other medical fluids can be added into chemical feed pipe by syringe in saline injection.
Further, part of the perfusion tube between chemical feed pipe and body-free transfusion puncture needle is equipped with liquid medicine filter.Pass through setting
Liquid medicine filter can prevent the bulky grain sundries in medical fluid to be injected into human body, guarantee transfusion safety.
Further, it is additionally provided with dropping funnel and flow regulator on conduit, so set, blood can be adjusted according to different patients
The flow velocity of liquid or medical fluid.
Further, the second filter screen for filtering blood impurity is equipped in dropping funnel, it can be to avoid by the second filter screen
Impurity injection in blood guarantees transfusion safety into human body.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of double-end blood transfusion apparatus embodiment of the utility model.
Specific embodiment
The utility model is described in further detail below by specific embodiment:
Description of symbols: blood transfusion puncture needle 1, body-free transfusion puncture needle 2, blood transfusion tube 3, perfusion tube 4, liquid medicine filter 5, reflux
