Description
Technical field
This utility model relates to medical apparatus and instruments, particularly to the haemostatic valve for Vascular haemostasis.
Background technology
Hemostatic valve is the indispensable spare part that percutaneous coronary gets involved operation, and this accessory is for being connected to the tail of guiding catheter
End, by artificial control, enters passage coronarius as apparatuses such as seal wire, sacculus and supports.
Haemostatic valve the most on the market mostly is single valve and double valve, uses single valve for conventional coronary procedure
Haemostatic valve the most enough, but for complicated vascular lesion, needs to use two seal wires to carry out single valve behaviour during interventional therapy
Make to exist some inconveniences: two seal wires due to from a valve the most out, easy adhesion and winding, need external artificially
Separation fix.
Y type haemostatic valve is conventional double valve haemostatic valve, and when needing to use two seal wires to carry out interventional therapy, seal wire is permissible
Respectively by two valves out, it is possible to be prevented effectively between seal wire and be mutually wound around interference, it is ensured that treatment is smoothed out.But Y type
Haemostatic valve there is also some shortcomings: due to many valves, its volume becomes big, stores and use inconvenience, and doctor can not basis
The change flexible operating of the treatment state of an illness；Secondly, in the middle of the process of change of equipment, still suffer from the situation that seal wire is subjected to displacement, impact
Operation process.
Utility model content
The purpose of this utility model is to provide a kind of U-shaped haemostatic valve, its simple in construction, it is possible to realize single valve and bivalve is flexible
Conversion, and seal wire is effectively fixed, easy to operate, substantially reduce operating time, it is ensured that patient safety.
The technical scheme that this utility model provides is as follows:
A kind of U-shaped haemostatic valve, carries arm including the liquid being connected with medical apparatus and instruments being arranged at main pipe side, with
It is provided with the first haemostatic valve on one mouth of pipe of the U-tube part that main pipe one mouth of pipe connects, another mouth of pipe is provided with unidirectional
Automatic closing valve.
Preferably, unidirectional automatic closing valve connects detachable second haemostatic valve parts.
Preferably, it is connected by screw-cap is fixing with detachable second haemostatic valve parts to automatic closing valve.
Preferably, another mouth of pipe of main pipe is provided with public female Luer.
Preferably, in the U-tube part of the first haemostatic valve, it is provided with seal wire fixed component.
Preferably, seal wire fixed component fits together with the tube wall of U-tube part, and the fixing end of seal wire fixed component comprises
There is 2-3 slotted eye, be used for fixing seal wire.
Preferably, the width of slotted eye is 1.5-2cm, and the degree of depth is 1.5-2.5cm.
Preferably, the material of seal wire fixed component is medical elastic rubber.
The U-shaped haemostatic valve that this utility model provides, has a dismountable haemostatic valve, can realize according to actual needs
Single valve and the conversion of double valve, simple in construction, convenient use.Meanwhile, it is additionally provided with seal wire fixed part in this U-shaped haemostatic valve
Part, can be used for arteria coronaria inner guide wire carrying out locking and fixing, prevents it from skidding off, deeply causes complication；Seal wire fixed part simultaneously
Part end face offers some slotted eyes, is used for distinguishing seal wire when using many seal wires, improves success rate of operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the U-shaped haemostatic valve of this utility model；
Fig. 2 is use schematic diagram during this utility model U-shaped haemostatic valve employing single valve；
Fig. 3 is the structural representation of detachable second haemostatic valve；

In figure, 1-main pipe, 2-liquid conveying arm, 3-U type pipe fitting, 4-the first haemostatic valve, detachable second hemostasis of 5-
Valve member, 6-screw-cap, 7-public affairs female Luer, 8-seal wire fixed component, the unidirectional automatic closing valve of 9-, 10-slotted eye.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with the accompanying drawings and be embodied as
The utility model is described in further detail for mode.
A kind of U-shaped haemostatic valve, including: include the liquid being connected with the medical apparatus and instruments conveying being arranged at main pipe 1 side
Arm 2, a mouth of pipe of the U-tube part 3 being connected with main pipe 1 one mouth of pipe is provided with the first haemostatic valve 4, on another mouth of pipe
It is provided with unidirectional automatic closing valve 9.When need not use bivalve, as long as seal wire carries out operating by the first haemostatic valve 4,
Unidirectional automatic closing valve 9 ensure that the mouth of pipe Guan Bi of U-tube part 3, as shown in Figure 2.
When many seal wire interventional therapys of needs, now detachable second haemostatic valve parts 5 (as shown in Figure 3) are passed through spiral shell
Silk cap is fixedly connected with unidirectional automatic closing valve 9, the most unidirectional automatic closing valve 9 and dismounting the second haemostatic valve parts 5 shape
Becoming path, seal wire can be entered by the second haemostatic valve, uses state diagram as shown in Figure 1.
Such as Fig. 1, shown in 2 and 4, inside the U-tube part 3 of the first haemostatic valve 4, it is being provided with seal wire fixed component 8, seal wire
The curved end of fixed component 8 fits together with the tube wall of U-tube part, and the fixing end of seal wire fixed component includes 2-3
Slotted eye 10, the width of slotted eye 10 is 1.5-2cm, and the degree of depth is 1.5-2.5cm.Slotted eye carries out locking and fixes seal wire, prevents it
Skid off, deeply cause complication；If be used for distinguishing seal wire when using many seal wires simultaneously, improve success rate of operation.
Haemostatic valve U-shaped to one provided by the utility model is described in detail above.Used herein specifically
Principle of the present utility model and embodiment are set forth by individual example, and the explanation of above example is only intended to help to understand this
The core concept of utility model.It should be pointed out that, for those skilled in the art, new without departing from this practicality
On the premise of type principle, it is also possible to this utility model is carried out some improvement and modification, these improve and modification also falls into this reality
With in novel scope of the claims.
