Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of drainage system, relates in particular to a kind of novel drainage system that can effectively remove obturator.This drainage system can effectively improve the inadequate drainage that causes owing to obstruction in the drain process, is convenient to the clinicist and nurses sufferer, to reduce the discomfort of sufferer.
Background technology
At present, usually get rid of afterwards gas and the liquid of thoracic cavity or intraperitoneal accumulation with drainage tube in operation, this is a kind of extraordinary clinical treatment means.But existing most drainage tubes are a kind of simple silica gel or pvc pipe, not specially for the structural design that can effectively process obturator when the tube chamber internal congestion.For general thoracic cavity or abdominal operation, the drainage effect of existing general drainage pipe still can.But for a lot of patients, if any larger wound or the with serious pollution patient of intracavity, the hydrops of its body cavity inside is thickness comparatively, often with block or cotton-shaped secretions, and need long-time placing drainage, use in this case the general drainage pipe to be very easy to form and block.If can not in time dispose obturator this moment, meeting and then forms adverse influence to patient so that the drainage function of drainage tube weakens even completely loses.Just need to take measures to remove the obturator of drainage tube inside this moment, perhaps changes drainage tube.Even if but can remove obturator, and its process also quite wastes time and energy, and needs to consume a large amount of time energy, also brings huge misery and uncomfortable to the patient simultaneously, and serious even threat to life is changed drainage tube and has then been brought extra financial burden to the patient.
In patent US2011/0040286A1, a kind of structural design of removing obturator in the drain process is disclosed.This structure mainly is to have placed a cleaning piece with Magnet in drainage tube, guides the reciprocating motion of the seal wire of drainage tube inside by being arranged on the outer Magnet of drainage tube, and then realizes the removing of obturator.This design can in the situation of not destroying the inner gnotobasis of drainage tube, realize the removing of obturator.But also there is the following problem in this design: at first, the motion of the seal wire of drainage tube inside is to be undertaken by the attraction of magnetic force, this is a kind of contactless force, therefore just might occur not enough when external magnet magnetic force or when disturbed by external magnetic field and cause effectively to drive the situation that internal cleaning spare moves, it is more particularly to work as obturator, when blocking comparatively " closely ", this situation appears especially easily, at this moment, the drainage function of drainage tube will be affected, even forfeiture, the crisis patients ' lives; Secondly, the Magnet volume that is exactly drainage tube inside is larger, and the internal diameter of original drainage tube is just limited, and the large volume of inner magnet has further occupied the volume of drainage tube inside, has caused on the contrary the reduction of drainage tube drainage function; Again, this structural design cost is higher, also is a kind of extra burden for patient.Therefore we are for the problems referred to above, have developed a kind of simple and practically, can effectively remove the drainage tube of obturator.
Summary of the invention
The purpose of this utility model is to provide a kind of novel drainage system, and it can overcome the deficiency that existing drainage tube exists, smoothly with discharges such as the pneumatosis of inside, thoracic cavity, hydrops.Guaranteeing not destroy in the situation of the inner gnotobasis of drainage tube, when occuring to block, in time conveniently remove obturator.
The purpose of this utility model is achieved through the following technical solutions:
