Abstract
A grades mode Y type haemostasis valve comprises a Y type pipe (10); a joint (20) and a cap (30) respectively connected on both mouths of the pipe (10). The cap (30) comprises a bonnet (31) in threaded connection with the mouth of the Y type pipe (10), a spring seat (32) disposed in the bonnet (31) and a spring (33) disposed between the spring seat (32) and the bonnet (31); also comprises an elastic silica gel piece (34) having cross incisions (341) at middle and a grade position wrench (35); the elastic silicon gel piece (34) is disposed on the spring seat (32); the grade position wrench (35) is in movable connection with the bonnet (31) with one end sustained to the elastic silica gel piece (34) and the other end exposed on the outer surface of the bonnet (31). The haemostasis valve of the utility model can achieve better haemostasis effect in the process of assisting guide wire and conduit to enter blood vessel; and has three grade positions for controlling, achieves convenient operation and simple structure.
Description
Technical field
This utility model relates to medical apparatus and instruments, particularly is used for blood vessel hemostatic haemostatic valve.
Background technology
At present, known Y type haemostatic valve structure is by single Y spare, joint, buckles medicated cap and assemble.After seal wire or foley's tube buckled medicated cap one end and enter into human vas from Y type haemostatic valve, buckle elastica and seal wire or the conduit fluid-tight engagement that install the medicated cap the inside by Y type haemostatic valve, and reach the hemostatic effect.And the medicated cap of buckleing of a lot of Y type haemostatic valve designs to such an extent that be not quite reasonable, and what have passes through rotation with membrane closure, and the operating time is long, and amount of bleeding is more, and it is poor to cause haemostatic effect; Passing through of having place in the structure the inside of button medicated cap 3 different apertures (be respectively sealing state, be fit to the state that state that seal wire passes through and suitable conduit pass through) elastica, seal wire or conduit are along 3 film intravasations, and the film of the 3rd sealing just can play the hemostatic effect.But the shortcoming of this method is inconvenient operation, production cost height, causes to cost an arm and a leg, operation doctor's level is had relatively high expectations.
Summary of the invention
This utility model provides a kind of stepping formula Y type haemostatic valve, employing is acted directly on the silica gel valve block by the operation spanner that is exposed to outer surface, control its centre bore and produce different apertures, be applicable to different instrumentations or sealing, solve complex operation, the not good technical problem of haemostatic effect in the prior art.
The scheme that this utility model solves the problems of the technologies described above is: this stepping formula Y type haemostatic valve comprises Y-piece spare, be connected to joint and button medicated cap on two mouths of pipe of Y-piece spare, described button medicated cap comprises the bonnet of the Y-piece spare mouth of pipe that is threaded, be arranged at the spring base in the bonnet, the spring that between spring base and bonnet, is provided with, the flexible silicon film and the gear spanner that have the intersection otch in the middle of also comprising, this elastic silica gel sheet is located on the spring base, described gear spanner is movably connected on the bonnet, the one end is against the flexible silicon film, the other end is exposed to the bonnet outer surface, and described intersection otch is cross recess or star otch.
The beneficial effects of the utility model are, can reach better haemostatic effect in the process of assisting seal wire and conduit intravasation, and adopt three gears controls, and are easy to operate, simple in structure.
Description of drawings
Fig. 1 is that the master of this utility model stepping formula Y type haemostatic valve looks sketch map.
Fig. 2 is this utility model bonnet place partial structurtes cross-sectional schematic.
Fig. 3 a, 3b, 3c are the centre bore sketch map of this utility model flexible silicon film under three range states.
The specific embodiment
Describe specific embodiment of the utility model in detail in conjunction with above-mentioned accompanying drawing.
By among Fig. 1 to Fig. 3 as can be known, this stepping formula Y type haemostatic valve comprises Y-piece spare 10, is connected to joint 20 and button medicated cap 30 on two mouths of pipe of Y-piece spare 10; Described button medicated cap 30 comprises the bonnet 31 of Y-piece spare 10 mouths of pipe that are threaded, be arranged at the spring base 32 in the bonnet 31, the spring 33 that between spring base 32 and bonnet 31, is provided with, the flexible silicon film 34 and the gear spanner 35 that have intersection otch 341 in the middle of also comprising, this flexible silicon film 34 is located on the spring base 32, described gear spanner 35 is movably connected on the bonnet 31, and the one end is against flexible silicon film 34, and the other end is exposed to bonnet 31 outer surfaces.Spring is in order to three gears of conveniently regulating and controlling Y type haemostatic valve, and elastic silica gel can be with the change of Y valve gear, and shape also changes, so that the smooth intravasation of seal wire or sacculus dilating catheter and oozing of blood or leak blood not.When the button medicated cap was positioned at first grade, elastic silica gel was in complete closure state; Be used for the mouth of sealing duct this moment, avoids blood to flow out from conduit mouth; Put second grade position with have gentle hands Pressing fastener medicated cap, elastic silica gel is slightly opened, but perusal do not go out, and this size of opening is convenient to seal wire and is entered human vas, and oozing of blood can not take place in the process that enters or leak the blood phenomenon; When bonnet is in second grade (being semi-closed state), during from Y valve side shoot injection contrast agent or other liquid, bonnet can fall back on first grade (being complete closing state) automatically, and is more safe and reliable, one-handed performance is just passable, and traditional haemostatic valve all needs doctor's bimanualness.Place the position of third gear with hands Pressing fastener medicated cap, elastic silica gel is opened fully, enter human vas in order to sacculus dilating catheter this moment, the size of the size of sacculus dilating catheter and selection Y type haemostatic valve need match fully, so that conduit and the silica gel of opening fully can be combined closely, thus the oozing of blood when stoping the conduit intravasation or leak the blood phenomenon.
Described intersection otch 341 is cross recess or is the star otch.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
