Venous transfusion means be widely used in clinical practice.And CVC needs conventional tube sealing to safeguard after infusion-completed,
To ensure clearness of catheter, it is easy to Long-Time Service.Traditional tube sealing method is first to be given birth to 10 milliliters of syringe pump 6-8 milliliters
Reason salt solution carries out washing pipe, is allowed to front institute's loading liquid completely into blood circulation, then with 5 milliliters of syringe pump 3-5 milliliter heparin
Natrium brine carries out pulsed positive pressure tube sealing.Whole process medical personnel need to consume two syringes, and a tube sealing mistake
Twice punctures of the Cheng Zaocheng to ductus venosus calparine cap, increases the damage to calparine cap and pollution probability.
Utility model content
The purpose of this utility model is to provide and a kind of the damage to calparine cap and pollution probability can be reduced in tube sealing
The special tube sealing suit of central venous catheter.
To reach above-mentioned purpose, the utility model is employed the following technical solutions：A kind of special envelope of central venous catheter
Pipe box is filled, it is characterised in that：The injection inner core in the injection outer tube is co-axially located at including an injection outer tube and one, described
Slide in injection inner core and a first piston is set, the first piston is fixedly connected with a push rod, the end of the push rod is arranged
Have one first by hand；Slide in the annular housing being made up of with the injection outer tube the injection inner core and one second work is set
Plug, the second piston is annular in shape and is nested with the injection inner core；The second piston is connected with the pushing cylinder fixation of an annular
Connect, the end of the pushing cylinder is provided with annular second by hand；The push rod is passed through from the described second centre bore by hand；
The front end of the injection inner core is provided with the first liquid outlet, and the front end of the injection outer tube is provided with the second liquid outlet, described
First liquid outlet connects the first port of a triple valve by flexible pipe, and second liquid outlet connects the triple valve by flexible pipe
Second port, the 3rd port of the triple valve connects an injection head；The triple valve has two gears, the triple valve
In the first gear when connect second liquid outlet and the injection head；When the triple valve is in the second gear, connection is described
Connection between first liquid outlet and the injection head and cut-out second liquid outlet and the injection head.
The beneficial effects of the utility model：The utility model when in use, loads liquaemin salt solution in injection inner core,
Load physiological saline in annular housing between injection outer tube and injection inner core, then injection head is connected with ductus venosus, will
Triple valve is adjusted to the first gear, by by hand propelled second piston by physiological saline in ductus venosus, then by triple valve
Be adjusted to the second gear, by by hand propelled first piston by Calciparine/sodium salt water injection in ductus venosus, whole tube sealing process, only
Ductus venosus calparine cap need to be punctured once, effectively reduce and which is damaged and probability is polluted.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail.These accompanying drawings are simplified schematic diagram,
Basic structure of the present utility model is only illustrated in a schematic way, therefore which only shows the composition relevant with the utility model.
As shown in figure 1, the utility model includes that an injection outer tube 1 and is co-axially located in the injection in injection outer tube 1
Cylinder 2, slides in injection inner core 2 and arranges a first piston 3, and first piston 3 is fixedly connected with a push rod 4, and the end of push rod 4 sets
One is equipped with by hand 5.Slide in the annular housing being made up of with injection outer tube 1 injection inner core 2 and a second piston 6 is set, second
Piston 6 is annular in shape and is nested with injection inner core 2.Second piston 6 is fixedly connected with the pushing cylinder 7 of an annular, and the end of pushing cylinder 7 sets
Be equipped with annular by hand 8.Push rod 4 is passed through from the centre bore by hand 8.The front end of injection inner core 1 is provided with the first liquid outlet
9, the front end of injection outer tube is provided with the second liquid outlet 10, the first liquid outlet 9 connects the first of a triple valve 11 by flexible pipe
Port, second port of second liquid outlet 10 by flexible pipe connecting tee valve 11, the 3rd port connection one of triple valve 11 are injected
12.Triple valve 11 has two gears, and when triple valve 11 is in the first gear, the second liquid outlet 10 is connected with injection head 12
It is logical；When triple valve 11 is in the second gear, the first liquid outlet 9 is connected with injection head 12 and cuts off the second liquid outlet 10 and injection
