Abstract
The utility model discloses a blood vessel guide pipe sheath sleeve suit which comprises a puncture needle and a guide pipe sheath which is sleeved on a puncture needle pipe, the guide pipe sheath is in sliding seal contact with the puncture needle pipe, the tail end of the puncture needle pipe is connected with a puncture needle pipe seat, and the tail end of the guide pipe sheath is connected with a guide pipe sheath seat. A lock mechanism arranged between the puncture needle seat and the guide pipe sheath seat is provided with a connection port I communicated with the guide pipe sheath, the puncture needle pipe seat is provided with a connection port II communicated with the puncture needle pipe, and when the puncture needle pipe seat and the guide pipe sheath seat are locked, the front end of the puncture needle pipe is stretched out of the guide pipe sheath. According to the blood vessel guide pipe sheath sleeve suit, the puncture needle pipe and the guide pipe sheath are compounded in one device, the puncture needle pipe and the guide pipe sheath utilize the special match and connection structure, when the guide pipe sheath is placed in a portal vein in an intervention mode, operation simplicity is achieved, placing time is greatly shortened, and pain and complications of patients are lowered.
Description
Technical field
This utility model 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 first catheter sheath to be put into portal vein, place catheter sheath, use at present sedinger method (four step rule)
1; The B ultrasonic guiding is lower, and deep vein puncture needle (16G) inserts portal vein.
2; Extract nook closing member in the deep vein puncture needle, 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 deep vein puncture needle.
4; Extract deep vein puncture needle, 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 affected greatly.
Summary of the invention
Problem to be solved in the utility model is: a kind of vessel catheter sheath suit is provided, can shortens portal vein and get involved the time of placing catheter sheath.
In order to solve the problems of the technologies described above, this utility model comprises 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, 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, 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 from getting 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 rear side of elastic packing barrier film, and the interface I is positioned at the front side of elastic packing barrier film.
Insert conduit when getting involved for the ease of portal vein, and in order better to seal when inserting conduit, 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 threaded connection, 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 be conducive to 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.
For better anti-Hemostatic Oral Liquid flows out from the interface II, described interface II is provided with lid, and lid is threaded with the interface II.
This utility model beneficial effect: will puncture needle tubing and catheter sheath of this utility model is compounded among the device, puncture needle tubing and catheter sheath adopt special the cooperation and syndeton, make when portal vein is got involved the placement catheter sheath, simple to operate, greatly shorten standing time, reduce patient suffering and complication.
Description of drawings
Fig. 1 is structural representation of the present utility model;
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, catheter sheath 2 contacts with 1 slipper seal of puncture needle tubing, the slipper seal contact refers to that catheter sheath 2 and puncture needle tubing 1 are slidingly connected, and contact surface seals, airtight and water so that puncture needle tubing 1 does not have gas or liquid to enter 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 when suction and pumping blood.
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, be provided with locking mechanism between puncture needle base 5 and the catheter sheath seat 3, 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 and puncture needle base 5 are threaded.Also can adopt other lock construction between puncture needle base 5 and the catheter sheath seat 3, such as snap close, lock-screw etc.As long as can puncture needle base 5 is fixing with catheter sheath seat 3, puncture needle base 5 can be separated again getting final product with catheter sheath seat 3.
The front end of catheter sheath 2 is taper, and puncture needle tubing 1 front end is most advanced and sophisticated.So more be conducive to insert portal vein.
This catheter sheath suit laying method
B ultrasonic guiding is lower, disposable insertion vessel catheter sheath suit, and 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: complication.
