More preferably, 3 elastics are equidistant is embedded in rear cover, when being inserted into seal wire or conduit, can effectively stop the leakage of blood.
Preferably, the elastic column section is round or similar round.
Preferably, the rear cover is sheath lid, and it is hollow, inside set haemostatic valve.
Herein, " front end " refers to one end when haemostatic valve is placed on conduit close to conduit, and " rear end " refers to hemostasis
Far from one end of conduit when valve is placed on conduit.
Device manufacturing provided by the utility model is at low cost, using simplicity, can effectively mitigate tissue blood vessel damage, reduce and suffer from
Person's pain, can effectively prevent blood back when carrying out seal wire operation, smaller size of lead can be also placed in by utility model device
Pipe, so that the applicable scene of conduit greatly improves, clinical application is very extensive.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of interventional therapy conduit hemostasis device of the utility model.
Fig. 2 is a kind of sectional view of the body assembly of interventional therapy conduit hemostasis device of the utility model.
Specific embodiment
The technical solution of the utility model is described further below in conjunction with drawings and examples.
It as depicted in figs. 1 and 2, is a kind of interventional therapy conduit hemostasis device provided by the utility model, the device packet
Contain: body assembly and extension component, the body assembly includes:
Shell 11；
Setting is in the intracorporal supervisor 12 of shell；
The pipe joint element 13 of supervisor front end is set, connecting conduit 1 is used for；
The rear cover 14 of supervisor rear end is set；And
The haemostatic valve 15 of rear cover inner wall is set；
The extension component includes: it is connected to the side pipe 21 of supervisor, and, the three-way cock 22 of side pipe end is set, is used
In intravascular injection drug and rinse haemostatic valve.
The pipe joint element 13 selects conduit to connect knob, and conduit connection knob is internally threaded, and can pass through rotation
The mode of conjunction is fixedly connected with a variety of conduits.
The haemostatic valve 15 is made of several elastics 151；In preferred embodiment, the haemostatic valve 15 is by being spaced
It is embedded 3 elastics composition in rear cover inner wall side by side, capable of blocking supervisor 12, (seal wire/conduit/drug is all by the pipeline
Into in conduit 1, elastic is exactly to prevent from leaking blood herein), as shown in Figure 2.3 elastics are equidistant to be embedded in rear cover,
When being inserted into seal wire or conduit, it can effectively stop the leakage of blood.
The elastic column section is round or similar round.
The rear cover is sheath lid, hollow, inside sets haemostatic valve.
When in use, such as most of blood vessel interposing catheter seal wires are identical for the hemostasis device of the utility model, need to be first with life
It manages salt water or heparin water or other sterile solutions and the present apparatus is rinsed by three-way cock, close threeway after inner air is discharged
Switch；Physiological saline is enclosed in the present apparatus, avoids bringing air when surgical procedure into and enters Endovascular, then utilizes device
The mode screwed that is threaded through of front end connects and comes into endovascular catheter tip, at this time again by back cover hole, into leading
Silk carries out interventional procedure, can play the anti-return blood of the utility model and leak the effect of blood.In short, the utility model provides one
While kind effectively prevent conduit blood back and leakage blood in blood vessel intervention operation, it is further provided one is used for the injection of drug
Side pipe.Under the auxiliary of the utility model, utilization efficiency of the conduit in art can further improve, in special vascular conditions
The number of replacement vagina vasorum can be reduced down, reduce operation risk and financial burden.
Further, all component materials of the utility model can be selected from by one in latex, silica gel, high molecular material
Kind is several, and high molecular material is, for example, polypropylene, polystyrene, polyurethane, polyvinylidene alcohol, polycarbonate, nylon
With Delrin (polyoxymethylene resin) etc., the combination of high molecular material that can also be two kinds or more.In a preferred embodiment, institute
There is component to be all made of good biocompatibility, flexility and resists the medical silica-gel system for losing that performance is good and allows indwelling time long
At.
Further, the pipe joint element of the utility model has a variety of internal diameter models available, can be led according to difference
The outer diameter of pipe selects different internal diameters, and conduit described in the utility model is circular cross-section.
In one embodiment, the utility model pipe joint element 13 after flushing is connected to and has been placed in leading for blood vessel
Pipe end enters seal wire by the rear cover tapping of the present apparatus, and seal wire is by haemostatic valve 15, supervisor 12, conduit 1, subsequently into
Endovascular effectively avoids blood and passes through wire catheter at this time since the elastic 151 in haemostatic valve 15 is wrapped in seal wire
Between gap leak out.
In one embodiment, when intervention operation in the case where seal wire and conduit have been in Endovascular, because leading
Silk can not be directly open using catheter tip in conduit and carry out intravascular drug injection.It can be connected at this time in catheter tip
Utility model device carries out endovascular drug injection (such as contrast agent, heparin) by side pipe, thus facilitate operation into
One step carries out, and reduces the operation for exiting seal wire, reduces operation risk.
