Described silica gel valve 14 is fitted to the groove mouth of the first interface body end 15 between the releasing device 13 and the first interface body end 15, engage the first interface body end 15 by releasing device and fix.
The medical Y-shaped connector of the embodiment of the invention, described pressing device 11 also include one and cut off hole clipping 112, and as shown in Figure 3, described partition hole clipping 112 comprises that a blocked hole 1121 and discharges breach 1122; Described releasing device 13 also comprises a ladder buckle 133, and described ladder buckle 133 is provided with the level and smooth projection 1331 of stairstepping; The size of described ladder buckle 133 matches with the partition hole clipping 112 of pressing device with the position; Described ladder buckle 133 extends downwards outside the releasing device 13 at the end towards the described first interface body end 15, so that have certain elasticity, and this ladder buckle of finger presses when helping being hold by one hand.
When downward promotion pressing device, when its pressure surpasses the elastic force of spring, under the effect of pressure, hollow cylinder 113 is pushed through second perforate of releasing device 13 and the otch of silica gel valve 14, be communicated with the connecting pipe of Y joint, simultaneously, the blocked hole 1121 of the partition hole clipping 112 of pressing device 11 moves downward, cross the level and smooth projection 1331 of stairstepping of ladder buckle 133, be stuck on the blocked hole 1121, as shown in Figure 4, chucking is also being kept the opening of first interface 1, and the otch that the hollow cylinder 113 of pressing device 11 is pushed silica gel valve 14 open forms a passage, and the guiding device of medical apparatus and instruments such as guide wire is passed; End when the ladder buckle 133 of inwardly pushing releasing device 13, the level and smooth projection 1331 of the stairstepping of ladder buckle 133 is subjected to inside pressure and the disengaging blocked hole 1121 of inwardly withdrawing, after pressing device is discharged from blocked hole 1121, whole pressing device is owing to the thrust that spring makes progress is upspring, external force is eliminated, driving hollow cylinder 113 pops up, hollow cylinder 113 leaves silica gel valve 14, cut closure on the silica gel valve 14, the connecting pipe of the sealing Y joint and first connector 1, the connecting pipe of Y joint is in closed state, can prevent blood backflow (hemostasis) etc. in other medical apparatus and instruments of operation.
The medical Y-shaped connector of the embodiment of the invention, preferably, 11 hollow bulbs extend downwards described hollow cylinder 113 from top drilling along pressing device, its height is less than the height of pressing device 11, after pressing device 11 covers are received releasing device 13, hollow cylinder 113 can not touch silica gel valve 14, and promptly hollow cylinder 113 is after the pressing device cover is received releasing device, and it highly is equal to or less than the distance from the pressing device open pore to silica gel valve upper surface.
As shown in Figure 5, preferably, as a kind of embodiment, the releasing device of the embodiment of the invention also is provided with the single buckle 1321 of a rectangle in a relative side with the ladder buckle; As shown in Figure 6, pressing device 11 is provided with the single hole clipping 111 of a rectangle with partition hole clipping 112 relative sides; As shown in Figure 7, single hole clipping 111 sizes match with the single buckle 132 of releasing device 13 with the position, make pressing device 11 and releasing device 13 be mounted to one by buckle.Simultaneously, the level and smooth projection 1331 of the stairstepping of the ladder buckle in the releasing device 13 slides in the release breach 1122 of pressing device, from opposite side relative fixed pressing device 11 movably.When pressing device 11 is under pressure and when movable, the single buckle 1321 of releasing device and the level and smooth projection 1331 of the stairstepping of ladder buckle are can be along with the activity of whole pressing device movable, buckle or leave pressing device pressing device 11 single hole clipping 111 and discharge breach 1122.More preferably, described ladder buckle 133 extends the end of releasing device 13 downwards at the end towards the described first interface body end 15, also includes second projection 1332, and the jut of this second projection 1332 is higher than the level and smooth projection 1331 of stairstepping; The described first interface body end 15 is corresponding to the level and smooth projection 1331 of stairstepping of ladder buckle and the position between second projection 1332, one fin projection is set, make that in discharging the process of pressing device inwardly push ladder buckle 133 and use conveniently, design more meets hommization.
Preferably, as a kind of embodiment, the otch of described silica gel valve 14 is the otch that there is " ten " font the centre, and hollow cylinder 113 pushings that its openings of sizes is suitable in the pressing device 11 are passed.
Preferably, as a kind of embodiment, the first interface body end, 15 outsides are provided with two boss 151; Releasing device 13 outsides are provided with two containing holes 131, and its size matches with two boss 151 with the position, and two boss 151 can be snapped onto in two containing holes 131.After in silica gel valve 14 being placed on the first interface body end, 15 vertical grooves; Releasing device 13 is socketed in the first interface body end, 15 outsides, makes in two containing holes 131 of the releasing device 13 that two boss 151 of the first interface body end 15 snap onto; Like this, releasing device 13 has been fixed together with regard to being connected with the first interface body end 15, and silica gel valve 14 fixing cards are pressed between the two.
As a kind of embodiment, the use of medical Y-shaped connector that the embodiment of the invention is described in further detail below is as follows:
1) use of unlatching medical Y-shaped connector is as follows:
At first, the singlehanded pressing device 11 that promotes downwards, spring 12 is compressed, and the single hole clipping 111 that makes pressing device 11 is separated with the single buckle 132 of releasing device 13, and single buckle 132 enters in the space between pressing device 11 and the releasing device 13;
Then, hollow cylinder 113 compresses springs 12, pushes " ten " notched cut of silica gel valve 14 open, blocks the stairstepping projection 1331 of ladder buckle 133 up to the blocked hole 1121 of pressing device 11;
After this, unclamp pressing device 11.
At this moment, medical Y-shaped connector remains in opening, and the hollow parts of pressing device 11 hollow cylinders 113 and silica gel valve 14 open " ten " notched cut form a passage, and other medical apparatus and instruments are passed through.
2) it is as follows to close the medical Y-shaped connector use:
When medical Y-shaped connector is in opening,
At first, one hand clicks end second projection 1332 of the ladder buckle 133 of releasing device 13, the level and smooth projection 1331 of the stairstepping of ladder buckle 133 is separated with blocked hole 1121 and is entered into and discharges breach 1122, spring 12 stretches, pressing device 11 is upwards promoted, and hollow cylinder 113 leaves silica gel valve 14 and opens " ten " notched cut;
Then, pressing device 11 moves upward, and when pressing device 11 stop motions, " ten " notched cut of silica gel valve 14 is closed.
At this moment, medical Y-shaped connector is in closure state, and " ten " notched cut of silica gel valve 14 is closed, and can stop blooding in other medical apparatus and instruments of operation.
The medical Y-shaped connector of the embodiment of the invention is simple in structure, is easy to manufacture; One-handed performance is simply, easily and fast: in the process that medical Y-shaped connector is used, only need the singlehanded pressing device that promotes, just can make medical Y-shaped connector be in opening.Only need the singlehanded end that clicks the ladder buckle, but just medical Y-shaped connector is in closure state.
Should be noted that at last that obviously those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these revise and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification.
