The limitation of the utility model.
Referring to Figures 1 and 2, in this preferred embodiment, a kind of negative pressure drum connector for nasobiliary drainage, including inner tube 1
And it is placed on the swivel nut 4 outside inner tube 1, wherein the both ends of inner tube 1 are respectively male connector 2 and female 3, and negative pressure rouses drainage tube and male connector 2
Connection, female 3 are connected with nose bile duct, and the setting of 1 inner hollow of inner tube is roused in drainage tube and female 3 with the negative pressure being connected in male connector 2
Nose bile duct, inner tube 1 is externally provided with the pipe clamp 5 of multi-clove type structure, and inner tube 1 is connect by pipe clamp 5 with 4 inclined-plane of swivel nut, and pipe clamp 5 is close
1 male connector of inner tube, 2 one end clamps the negative pressure drum drainage tube in male connector 2 after the extrusion deformation of swivel nut 4.
Negative pressure drum drainage tube and nose bile duct are the plastic circular hose with certain elasticity.Pipe clamp 5 is certain elasticity
Rigid plastics is made.Further, pipe clamp 5 is provided with the block 6 for preventing swivel nut 4 from slipping close to 2 one end of male connector.
In the present embodiment, the end of male connector 2 is provided with for being inserted in the cone mouth playing the guiding role to negative pressure drum drainage tube,
The diameter of 2 end cone mouth of male connector is less than negative pressure drum drainage bore, had not only facilitated and male connector 2 is inserted into negative pressure drum drainage tube, but also protected
Hindering male connector 2 can be by negative pressure drum drainage tube stay deformation, to have the function that male connector 2 and the negative pressure drum drainage seal of tube.Outside male connector 2
Diameter is greater than negative pressure drum drainage bore, has ensured that negative pressure drum drainage tube can be slided easily in male connector 2, has ensured quickly
Dismount connector.
The end of female 3 is provided with for being inserted in the cone mouth playing the guiding role to nose bile duct.The length of cone mouth in female 3
Greater than the length of cone mouth in male connector 2.The diameter of 3 end cone mouth of female is less than nose bile duct internal diameter, and 3 outer diameter of female is greater than in nose bile duct
Diameter.After 3 conical surface of female is inserted into nose bile duct, with screwing for swivel nut 4, nose bile duct is slowly deformed on 3 inclined-plane of female, thus
Lock sealing is realized on the inclined-plane of 3 cone mouth of female, until rotation 4 female 3 of swivel nut and nose bile duct relative displacement are not occurring.
In the present embodiment, pipe clamp 5 is used with flowering structure: pipe clamp 5 is made of multiple valves of being in charge of, adjacent two be in charge of between valve lead to
Fluting interval is crossed, is in charge of valve and includes the guide part being obliquely installed and be fixed on guide part close to the interconnecting piece of 3 side of female, be somebody's turn to do
Interconnecting piece is fixedly connected with inner tube 1, and swivel nut 4 is placed on the outside of guide part, and guide part is set between one end and inner tube 1 of male connector 2
There is gap, when rotating the clamping pipe clamp 5 of swivel nut 4, guide part clamps negative pressure drum drainage tube after the deformation of one end of male connector 2.Gear
Block 6 is fixed on guide part on one end of interconnecting piece.Multiple guide parts for being in charge of valve form a frustum cone structure.
This negative pressure for being used for nasobiliary drainage rouses connector, and the use process is as follows.
Swivel nut 4 is held, first connects male connector 2 with negative-pressure drainage tube, until negative pressure drum drainage tube enters in pipe clamp 5, and
The block 6 being arranged by 5 head of pipe clamp prevents swivel nut 4 from slipping.Negative pressure drum drainage tube is that the plastic circular with certain elasticity is soft
Pipe.Because 2 outer diameter of male connector is slightly larger than negative pressure drum drainage bore, the diameter of 2 head cone mouth of male connector is less than negative pressure drum drainage bore,
Facilitate and male connector 2 is inserted into negative pressure drum drainage tube, and ensures that male connector 2 can be by negative pressure drum drainage tube stay deformation, to reach
The effect of male connector 2 and the negative pressure drum drainage seal of tube；Simultaneously also because 2 outer diameter of male connector is ensured slightly larger than negative pressure drum drainage bore
Negative pressure drum drainage tube can be slided easily in male connector 2, ensure quick dismounting connector.
Then, swivel nut 4 is screwed, female 3 is connected with nose bile duct.After 3 cone mouth of female is inserted into nose bile duct, with swivel nut 4
Screw, nose bile duct slowly deforms on 3 cone mouth inclined-plane of female, to realize lock sealing on 3 cone mouth inclined-plane of female, directly
There is not relative displacement to female 3 when rotating swivel nut 4 and nose bile duct.
Swivel nut 4 is that inclined-plane connects with pipe clamp 5, and being each in charge of between valve has fluting to separate.Female 3 and nose bile duct lock sealing
Afterwards, continue to rotate swivel nut 4, swivel nut 4 and pipe clamp 5 generate relative displacement, and pipe clamp 5 deforms, and the negative pressure drum compressed in male connector 2 draws
Flow tube, prevent negative tube drainage tube using when there is unexpected fall off.
The negative pressure drum connector for nasobiliary drainage that the present embodiment proposes, structure is simple, easy to use, solves well
The problem of negative pressure of having determined drum drainage tube and nose bile duct quickly connect.Meanwhile this negative pressure drum connector for nasobiliary drainage is connecting
After connecing, negative pressure drum drainage tube and nose bile duct are all not easy to fall off, ensure that its bonding strength and job stability.
The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure transformation made based on the specification and figures of the utility model, it is relevant to be applied directly or indirectly in other
Technical field is also included in the patent protection scope of the utility model.
