Abstract
The invention discloses a vessel catheter sheath assembly, which comprises a puncture needle and a catheter sheath sleeved on a puncture needle tube, wherein the catheter sheath is in sliding hermetic contact with the puncture needle tube; a puncture needle tube seat is connected to the tail end of the puncture needle tube; a catheter sheath seat is connected to the tail end of the catheter sheath; a locking structure is arranged between the puncture needle tube seat and the catheter sheath seat; the catheter sheath seat is provided with an interface I which is communicated with the catheter sheath; the puncture needle tube seat is provided with an interface II which is communicated with the puncture needle tube; and when the puncture needle tube seat is locked together with the catheter sheath seat, the front end of the puncture needle tube extends out of the catheter sheath. The puncture needle tube and the catheter sheath are compounded in a device, and special matching and connecting structures are adopted for the puncture needle tube and the catheter sheath, so that operation is easy during placement of the catheter sheath in portal vein intervention, the placing time is shortened greatly, and pain and complications of a patient are reduced.
Description
Technical field
The present invention relates to a kind of medical treatment device, particularly a kind of vessel catheter sheath.
Background technology
When vascular interventional treatment, especially get involved at portal vein, need earlier catheter sheath to be put into portal vein, place catheter sheath, use sedinger method (four step rule) at present
1; Under the B ultrasonic guiding, deep vein puncture pin (16G) inserts portal vein.
2; Extract nook closing member in the deep vein puncture pin, whether the empty needle suction has blood to flow out.
3; Confirm that step 2 has blood to flow out, and inserts the soft seal wire of " J " type to portal vein through the deep vein puncture pin.
4; Extract the deep vein puncture pin, insert catheter sheath through seal wire.
There is blood to flow out through catheter sheath three-way cock suction, proves that catheter sheath inserts smoothly.
Because catheter sheath and puncture needle are separate, in use, operating procedure is many, the time is long, and the patient is influenced greatly.
Summary of the invention
The problem that the present invention will solve is: a kind of vessel catheter sheath suit is provided, makes it can shorten portal vein and get involved the time of placing catheter sheath.
In order to solve the problems of the technologies described above; The present invention includes puncture needle and the catheter sheath that is enclosed within on the puncture needle tubing, catheter sheath contacts with the slipper seal of puncture needle tubing, and the tail end of puncture needle tubing is connected with the puncture needle base; The tail end of catheter sheath is connected with the catheter sheath seat; Be provided with locking mechanism between puncture needle base and the catheter sheath seat, the catheter sheath seat is provided with the interface I that communicates with catheter sheath, and the puncture needle base is provided with the interface II that communicates with the needle tubing that punctures; When puncture needle base and the locking of catheter sheath seat, the front end of puncture needle tubing stretches out catheter sheath.
Blood flows out through catheter sheath when preventing to get involved, and is provided with the elastic packing barrier film in the described catheter sheath seat, and the puncture needle tubing interts in the elastic packing barrier film, and the puncture needle base is positioned at the membranous rear side of elastic packing, and the interface I is positioned at the membranous front side of elastic packing.
Insert conduit when getting involved for the ease of portal vein, and in order when inserting conduit, better to seal, described elastic packing barrier film is provided with cross and isolates band, the puncture needle tubing interts and isolates band central authorities at cross.
In order to make locking and the convenient for unlocking between puncture needle base and the catheter sheath seat, puncture needle base and catheter sheath seat are through being threaded, and described locking mechanism is the screw connection structure between puncture needle base and the catheter sheath seat.
In order to treat at the interventional therapy Chinese medicine, described interface I is connected with three-way cock.
Thrust portal vein in order more to help this catheter sheath suit, the front end of described catheter sheath is taper, and described puncture needle tubing front end is most advanced and sophisticated.
In order to prevent that better blood from flowing out from the interface II, described interface II is provided with lid, and lid is threaded with the interface II.
Beneficial effect of the present invention: will puncture needle tubing and catheter sheath of the present invention is compounded among the device; Puncture needle tubing and catheter sheath adopt special cooperation and syndeton, make when portal vein is got involved the placement catheter sheath, and be simple to operate; Shorten standing time greatly, reduce patient suffering and complication.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1, puncture needle tubing, 2, catheter sheath, 3, the catheter sheath seat, 3-1, interface I, 4, the elastic packing barrier film, 5, the puncture needle base, 5-1, interface II, 6, three-way cock, 7, lid.
The specific embodiment
A kind of specific embodiment as shown in Figure 1; It comprises puncture needle tubing 1 and the catheter sheath 2 that is enclosed within on the puncture needle tubing 1, and catheter sheath 2 contacts with 1 slipper seal of puncture needle tubing, and the slipper seal contact is meant that catheter sheath 2 and puncture needle tubing 1 are slidingly connected; And contact surface seals; Airtight and water makes puncture needle tubing 1 when suction and pumping blood, not have gas or liquid to get into puncture needle tubing 1 from the position that catheter sheath 2 contact with puncture needle tubing 1, is convenient to blood smoothly from needle tubing 1 extraction of puncturing.
The tail end of puncture needle tubing 1 is connected with puncture needle base 5; The tail end of catheter sheath 2 is connected with catheter sheath seat 3, is provided with locking mechanism between puncture needle base 5 and the catheter sheath seat 3, and is as shown in Figure 1; Locking mechanism adopts screw connection structure in this specific embodiment; Be provided with female thread in the catheter sheath seat 3, puncture needle base 5 is provided with external screw thread, and catheter sheath seat 3 is threaded with puncture needle base 5.Also can adopt other lock construction between puncture needle base 5 and the catheter sheath seat 3, like snap close, lock-screw etc.As long as can puncture needle base 5 is fixing with catheter sheath seat 3, can puncture needle base 5 and catheter sheath seat be opened in 3 minutes again and get final product.
The front end of catheter sheath 2 is taper, and puncture needle tubing 1 front end is most advanced and sophisticated.So more help inserting portal vein.
This catheter sheath suit laying method
B ultrasonic guiding down, disposable insertion vessel catheter sheath suit, to portal vein, suction interface II 5-1 makes 1 suction of puncture needle tubing hemorrhage, extracts puncture needle tubing 1, has blood to flow out through three-way cock 6 suctions, proves that catheter sheath 2 inserts smoothly.
The advantage of this catheter sheath suit
1: laying method is simplified, and the four step rule by original becomes one-step method.
2: shorten catheter sheath standing time, by original about 30 minutes foreshorten to 3 minutes, reduce the patient suffering.
3: improve success rate.
4: reduce complication.
