Distance between left room pressure-measuring pipe rear port is 6～10 centimetres.Upper according to the different situations of patient, such as adult and child
Span between caval vein and left atrium there are differences, so designed that the structure of different model, to meet differentiation requirement.
Preferably, the front port of described syringe is helicitic texture, uses screw thread between syringe and tee T the second interface
Mode connects.
Preferably, described sleeve pipe is that soft material is made.
Preferably, for being flexibly connected between described deep vein catheter front port and tee T first interface, described syringe
Also it is flexibly connected with between tee T the second interface.
Further, described flexible connection is socket.
Further, described deep vein catheter rear port flushes with sleeve pipe side.
Remarkable result of the present utility model is: compare with traditional technology, this programme simple in construction, by being surveyed in left room
The body of pressure pipe and the body of deep vein catheter are integrated into same body, solve be presently required simultaneously use deep vein catheter and
The problem that left room pressure-measuring pipe intubates, alleviates patient suffering, has saved cost, also makes to nurse convenient simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model and operation principle are described in further detail.
As shown in Figure 1:
The deep vein catheter system of a kind of band left atrium pressure measuring function, including tee T 1, syringe 2, left room pressure-measuring pipe 3
With deep vein catheter 4.
The body of described left room pressure-measuring pipe 3 and the body of deep vein catheter 4 share same sleeve pipe 6, the most left room pressure-measuring pipe 3
The leading inlet of leading inlet and deep vein catheter 4 is in released state, and both are distributed in " bifurcation " shape.Make left room pressure-measuring pipe 3
Separating with the leading inlet of deep vein catheter 4, back outlet and body are same entirety, i.e. share the effect of sleeve pipe 6.
Left room pressure-measuring pipe rear port 301 is positioned at sleeve pipe 6 end, and deep vein catheter rear port is positioned at side in the middle part of sleeve pipe 6, institute
Stating deep vein catheter front port connecting tee pipe 1 first interface, described tee T 1 second interface connects syringe 2.
In practical operation, said structure meets deep vein catheter rear port and is positioned at the superior vena cava of human body, and left room is surveyed
Pressure pipe rear port 301 is positioned at human body left atrium.
Further, described tee T 1 the 3rd interface is provided with the flexible pipe 5 connecting infusion bottle.Flexible pipe 5 is inserted in infusion bottle glue
Beyond the Great Wall, infusion bottle is built with heparin saline.
Preferably, described deep vein catheter 4 is double pipe structure, including front port one, front port two and rear port 1,
Rear port 2 402, wherein the distance between rear port 1 and rear port 2 402 is 1～2 centimetre, by this section in the present embodiment
Apart from named second segment distance S2, wherein S2=2cm.
Further, the distance between described rear port 1 and sleeve pipe 6 head end is 15～20 centimetres, in the present embodiment
By named for this segment distance first paragraph distance S1, wherein S1=18cm；Described rear port 2 402 and left room pressure-measuring pipe rear port
Distance between 301 is 6～10 centimetres, and this segment distance is the 3rd segment distance, S3=10cm.
Preferably, the front port of described syringe 2 is helicitic texture, uses spiral shell between syringe 2 and tee T 1 second interface
Stricture of vagina mode connects.
Preferably, described sleeve pipe 6 is made for soft material.
