Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, the schematic diagram of the utility model push type Y-connector.Push type Y-connector includes Y-valve
Body, elastic Y-valve cap assembly, Y-valve adapter assembly, Y-valve body is circular tube structure, and Y-valve body includes that Y-valve body entrance point, Y-valve body extend
Section, Y-valve body interface end, seamless connection forms the whole of Y-valve body successively for Y-valve body entrance point, Y-valve body extension, Y-valve body interface end
Body, Y-valve body extension outside is provided with the injection junction block connected with Y-valve body extension inside, and elastic Y-valve cap assembly includes Y
Bonnet, rubber plug valve wedge, rubber plug valve, Y-valve cap is cylinder cap structure, the center of top of cylinder cap structure be provided with vertically to
The conducting tubular construction that Y-valve cap inside extends, rubber plug valve wedge is the circular tube structure that shaft section is assumed a " convex " shape, and conducting tubular construction is plugged
Slidably socket join structure is formed in the top small end cavity of rubber plug valve wedge, slidably Y-valve is arranged with the outside of socket join structure
Spring forms slidably elastic socket join structure, and Y-valve body entrance point stretches into Y-valve cap and formed with the big end cavity in the bottom of rubber plug valve wedge
Sealing connection, envelope is provided with the rubber plug valve between Y-valve body entrance point and rubber plug valve wedge, and pressing Y-valve cap is by turning on tubular construction
Free end top is opened or is taken out and closes rubber plug valve, and Y-valve body interface end is arranged with Y-valve adapter assembly, and Y-valve body is by Y-valve adapter assembly and finger
Guiding tube is connected.Such scheme employs hollow cylinder channel design, i.e., opening plug using hollow cylinder produces service aisle
Structure, presses during work and opens plug, rollback plug closure during reset so that service aisle is more succinct unobstructed.
In clinical practice, the effect of rubber plug valve is the unsuitable outflow of anti-Hemostatic Oral Liquid, but existing punched-type plug
The haemostatic effect of valve is not good.In order to improve the haemostatic effect of rubber plug valve, this programme employs positive and negative cross plug structure, such as Fig. 3
Shown, plug uses cross-rib structure so that seal wire is smaller through frictional force, and cutting mode is made using positive and negative cross cutting profile
Must be open sufficiently large and guarantee plug sealing.I.e. rubber plug valve is with certain thickness bi-concave elastic packing film, elasticity
Cross reinforcing rib structure is provided with the concave surface of sealed film, cross reinforcing rib structure is provided with cross and penetrates gap, presses Y-valve
Cap pushes up to open or take out by turning on the free end of tubular construction and closes cross and penetrate gap.When tubular construction insertion is turned on, cross-formed slits
Gap can allow it to pass through and twine to tie up to play a part of sealing thereon, and when tubular construction extraction is turned on, cross gap is closed automatically
Close in case Hemostatic Oral Liquid flows out.Further, in order to improve the sealing effectiveness of cross plug, convenient conducting tubular construction smoothly enters glue
Plug valve, this programme employs tapered cross and penetrates gap, i.e., front wide and rear narrow gap interface, i.e. the ten of the outside of rubber plug valve
The cross of the inner side that the A/F that font penetrates gap is more than rubber plug valve penetrates the A/F in gap, and this structure is being led
Through-pipe structure enters fashionable its outside width that has benefited from and is open and can smoothly insert, and has benefited from the inside of it turning on when tubular construction is exited
Narrow opening and preferable sealing effectiveness can be played.
The use of Y-connector for convenience so that the elastic operation of Y-valve cap easily facilitates operation technique, this programme is adopted
With block circulation channel design, i.e., using triangle circulation slider channel design, realize that bonnet presses the activity of resilience.Such as Fig. 4,
Shown in 5, the big end lateral wall in bottom of this programme rubber plug valve wedge is provided with elastic-buckle structure, and the madial wall of Y-valve cap is provided with
Projection cube structure, presses Y-valve cap, and projection cube structure forms elastic snapping with elastic-buckle structure, and the free end top for turning on tubular construction is opened
Rubber plug valve, it is big along rubber plug valve wedge bottom in the presence of Y-valve spring after elastic snapping that rotation Y-valve cap causes that projection cube structure departs from
Rotation return groove on the lateral wall of end moves back initial position, and the free end of conducting tubular construction is taken out and closes rubber plug valve.Above-mentioned buckle knot
The structural improvement of the structure and its self-return experience of Y-connector, simplifies operation technique.
In order to further improve the ease of use of Y-connector, this programme also discloses a kind of Y-valve free to rotate
Adapter assembly, i.e. rotary joint structure, using separate type combining structure at valve body and female Luer, are enclosed by O-shaped silica gel
To sealing function, realize that the public Rule of rotation will not be rotated with moving valve, it is easier to operate.As shown in Fig. 2 specifically Y-valve body connects
Circumferentially arranged with Y-valve collar eaves on the lateral wall of mouth end, Y-valve adapter assembly includes Rule male joint, sealing connecting component, and sealing connects
Connected components include Y-valve tetrafluoro packing ring, packing ring gland, O-shaped silica gel ring, and packing ring gland is set in Y-valve body interface end, packing ring gland
Envelope is provided with Y-valve tetrafluoro packing ring between Y-valve collar eaves inside bottom surface, and Rule male joint is set in and rotatable cunning is formed on packing ring gland
Dynamic socket, envelope is provided with O-shaped silica gel ring between Rule male joint and packing ring gland, and the one of Rule male joint being set on packing ring gland
End outside forms rotary sliding socket with Y-valve collar eaves inner side.Above structure causes that Rule male joint be free to and it
He connects medical device, the state without influenceing Y-valve body.
In order to extend the range of application of Y-connector so that the Y-connector of this programme can apply larger gauge catheter
Situation, this programme additionally uses inner chamber macroporous structure, i.e., the service aisle of whole product is designed using the big chamber of 3.2mm,
Can be by larger gauge catheter, the inner chamber latus rectum of specifically Y-valve body is 3.2mm.
The push type Y-connector of this programme is mainly used in PTCA operations, and auxiliary sets up guide wire entrance in vitro
The service aisle of human body, wherein Y-connector are used to help guide wire and enter human body.Public female Luer is connected when product is used
Guiding catheter, pressing bonnet open plug insertion guide wire after and rotate bonnet depart from buckle, bonnet is in spring pressure lower valve
Cap resilience returns to initial position, and guide wire enters human body through the plug of closure after plug closure.The push type Y types of this programme
Connector opens plug and produces service aisle structure using hollow cylinder so that service aisle is more succinct unobstructed.Using positive and negative ten
Word plug structure causes that seal wire is smaller through frictional force, and be open sufficiently large and guarantee plug sealing.Using block circulation passage
Structure realizes that bonnet presses the activity of resilience.The public Rule of rotation is realized using separate type combining structure at valve body and female Luer
Will not be rotated with moving valve, it is easier to operate.Based on above feature, the push type Y-connector of this programme is same compared to existing
Class product has substantive distinguishing features and progress.
The push type Y-connector of this programme is not limited to the content disclosed in specific embodiment, occurs in embodiment
Technical scheme can be with individualism, it is also possible to mutually include, those skilled in the art according to this programme combination common knowledge make
The simple alternative for going out falls within the scope of this programme.
