Description

Three chamber ditube drainage pipes
Technical field
This utility model relates to the technical field of medical apparatus and instruments, particularly relates to a kind of three chamber ditube drainage pipes.
Background technology
In prior art, the drainage catheter that department of general surgery thoracic cavity, abdominal postoperative are used, hospital's generic latex pipe self manufacture mostly, this homemade conduit can only play single drainage effect, and cannot to the dirt in thoracic, abdominal cavity carry out flushing remove, thus affect breast, after abdominal cavity operation treatment effect adopt, in addition, this conduit is comparatively hard, brings inconvenience to nursery work.It is better that existing Chinese patent CN202777383U discloses a kind of ditube drainage pipe practical function, but due to air inlet comparatively narrow, air inlet effect is undesirable, haves much room for improvement.
Utility model content
The purpose of this utility model is to solve the problem, and the basis of existing patent CN202777383U provides a kind of three chamber ditube drainage pipes.
The technical solution of the utility model is: a kind of three chamber ditube drainage pipes, comprise trocar sheath, interior pipe, pedestal and lid, described interior pipe is placed in trocar sheath inside, the front end of described trocar sheath is cecum, a conduction hole is provided with at the center of cecum, the front portion of trocar sheath is equipped with several trocar sheath conduction holes, the front portion of interior pipe is equipped with Tube Drain hole in several, the rear portion of described trocar sheath is connected with pedestal, through hole is provided with in the middle part of pedestal, described interior pipe passes from described through hole, the lid mated with pedestal is provided with in the outer end of interior pipe, it is characterized in that, described outer sleeve inner wall is provided with vertically a syringe pipe and a breather, syringe pipe, breather all synthesizes one with the inwall of trocar sheath, described syringe pipe, the front port of breather all penetrates trocar sheath cecum, the outer wall that described syringe pipe and trocar sheath are integrated is provided with some syringe pipe conduction holes, the outer wall that described breather and trocar sheath are integrated all arranges some breather passages with the outer wall being arranged in trocar sheath inner chamber, described pedestal is provided with pedestal limbers and pedestal passage, and pedestal limbers is communicated with syringe pipe through pedestal, and pedestal passage is communicated with breather through pedestal, described pedestal rear portion is provided with assembly cavity, and the front end of described lid is provided with an annular grooving, and annular grooving is set with annulus sealing ring, and the front end sleeve being set with the lid of annulus sealing ring loads in the assembly cavity at pedestal rear portion.
Described breather and syringe pipe are symmetric on outer sleeve inner wall.
The internal diameter of described breather is less than or equal to the internal diameter of described syringe pipe.
The front end of described interior pipe is at regular intervals apart from the front end of trocar sheath.
The outer end of described pedestal limbers and pedestal passage is separately installed with interface and cap stopper.
The cross section of the outer surface of described trocar sheath is circular.
The beneficial effects of the utility model
This utility model makes the gap between the trocar sheath in former patent and inner sleeve into breather, solve in use procedure not smooth problem of ventilating, trocar sheath is placed in abdominal cavity or thoracic cavity during use, connection water source, pedestal limbers can be rinsed as rinsed, interior pipe connects negative pressure device outward, interior pipe arbitrarily can move or extract cleaning out in trocar sheath in trocar sheath, such a construction ensures interior pipe not easily to block, improve drainage effect, avoid the problem of secondary intubate after blockage in the past, decrease the trouble of doctor and the misery of patient.
