Description
Technical field
This utility model is related to technical field of medical instruments, more particularly to a kind of sleeve pipe.
Background technology
Need to use sleeve pipe after human body fluid collection and separated body fluid, lid is typically stamped on sleeve pipe, for preventing
Only the body fluid in sleeve pipe leaks.In prior art, lid is mostly the opening for being stuck in sleeve pipe, and the shortcoming of this connected mode exists
Separate with lid with sleeve pipe in inconvenience.
Utility model content
To solve above-mentioned problems of the prior art, this utility model provides a kind of sleeve pipe, facilitates lid and sleeve pipe
Between separation.
The technical solution of the utility model is：A kind of sleeve pipe, including trocar sheath, inner sleeve and lid, the trocar sheath, institute
The one end for stating inner sleeve is opening, and the other end of the trocar sheath is blind end, and the other end of the inner sleeve is filter house,
The inner sleeve is placed in the trocar sheath, and the opening of the trocar sheath and the inner sleeve is end in the same direction, the lid
It is covered in the opening of the trocar sheath and the inner sleeve, the lid and the trocar sheath, the opening of the inner sleeve
Between for threaded connection.
The lid include diapire, the lateral wall and the medial wall on the inside of the lateral wall on the diapire,
The trocar sheath is threadedly coupled with the lateral wall, and the inner sleeve is threadedly coupled with the medial wall.
The opening of the trocar sheath arranges external screw thread, and on the lateral wall female thread is arranged.
The opening of the inner sleeve arranges external screw thread, and on the medial wall female thread is arranged.
The opening of the inner sleeve arranges female thread, and on the medial wall external screw thread is arranged.
Thread rotary orientation is identical with the thread rotary orientation on the inner sleeve on the trocar sheath.
Thread rotary orientation is contrary with the thread rotary orientation on the inner sleeve on the trocar sheath.
The filter house is filter membrane.
The filter house is several filtering holes for being arranged on the inner sleeve other end.
The utility model proposes sleeve pipe by will be set between lid and trocar sheath, the opening of inner sleeve screw thread connect
Connect, so as to facilitate lid to separate with trocar sheath, inner sleeve.
Description of the drawings
Fig. 1 is the structure chart of this utility model sleeve pipe；
Fig. 2 is the sectional view of the first embodiment of this utility model sleeve pipe；
Fig. 3 is the sectional view of second embodiment of this utility model sleeve pipe.
Specific embodiment
Such as Fig. 1, the utility model proposes sleeve pipe, including trocar sheath 10, inner sleeve 20 and lid 30.
Such as Fig. 2, one end of trocar sheath 10 is opening, and the other end of trocar sheath is blind end.One end of inner sleeve 20 is
Opening, the other end of inner sleeve is filter end.Inner sleeve 20 is placed in trocar sheath 10, and trocar sheath 10 and inner sleeve 20 are opened
Mouth end is end in the same direction, and lid 30 is covered in the opening of trocar sheath 10 and inner sleeve 20, lid 30 and trocar sheath 10, inner sleeve 20
Opening between for threaded connection.
Lid includes diapire 31, the lateral wall 32 and the medial wall 33 located at the inner side of lateral wall 32 on diapire 31, outward
Sleeve pipe 10 is threadedly coupled with lateral wall 32, and inner sleeve 20 is threadedly coupled with medial wall 33.
In the present embodiment, the opening of trocar sheath 10 arranges external screw thread, and on lateral wall 32 female thread is arranged.Inner sleeve 20
Opening arranges external screw thread, and on medial wall 33 female thread is arranged.
In the present embodiment, filter house has two kinds, and one is that filter house is filter membrane, and the film hole diameter of the filter membrane is 5-200 μ
m.Two are, filter house is several filtering holes for being arranged on the inner sleeve other end, a diameter of 5-200 μm of filtering holes.Filter house
Cell mucus and blood in for removing body fluid.
The distance between the filter house of inner sleeve 20 and the bottom surface of trocar sheath 10 are 5-80mm, are reserved in trocar sheath 10 certain
Space contains the liquid filtered out by inner sleeve 20, and the amount of liquid filtered out according to inner sleeve 20 determines the distance.
Such as Fig. 3, the present embodiment is with the first embodiment difference：The opening of inner sleeve 20 arranges female thread,
External screw thread is set on medial wall 33.
In the present embodiment, thread rotary orientation can be with identical with the thread rotary orientation on inner sleeve 20 on trocar sheath 10, it is also possible to phase
Instead, but it is equally applicable to the first embodiment.
The utility model proposes the mode that is threaded connection of sleeve pipe lid is connected with trocar sheath, inner sleeve, so as to
Lid is facilitated to separate with trocar sheath, inner sleeve.And, also cause lid to be connected more firm with trocar sheath, inner sleeve.
Only to illustrate design of the present utility model, one of ordinary skill in the art's specific embodiment above exists
Various deformation and change can be made under design of the present utility model, these deformations and change are included in guarantor of the present utility model
Within the scope of shield.
