Description
Technical field
The invention belongs to medical instruments field, relate to a kind of drainage system, relate in particular to a kind of drainage system that can effectively remove obturator.This drainage system can effectively improve the inadequate drainage that is caused 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, after operation, use drainage tube to get rid of thoracic cavity or cumulative gas of intraperitoneal and liquid usually, this is a kind of extraordinary clinical treatment means.But existing most drainage tubes are a kind of simple silica gel or pvc pipe, and are unspecial in the structural design that when the tube chamber internal congestion, can effectively handle obturator.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 big 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 the long-time drainage tube of placing, use the general drainage pipe to be very easy to form in this case and block.If can not in time dispose obturator this moment, can make drainage tube drain function reduction in addition completely lose, and then patient is formed adverse influence.Just need take measures this moment to remove the inner obturator of drainage tube, perhaps change drainage tube.Even if but can remove obturator, and its process also quite wastes time and energy, and needs to consume great 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 in the drain process, removing obturator is disclosed.This structure mainly is in drainage tube, to have placed a cleaning piece that has Magnet, guides the reciprocating motion of the inner seal wire of drainage tube through the Magnet that is arranged on outside the drainage tube, and then realizes the removing of obturator.This design can realize the removing of obturator under the situation of not destroying the inner gnotobasis of drainage tube.But also there is the following problem in this design.At first be, the motion of the seal wire that drainage tube is inner is to carry out through the attraction of magnetic force, and this is a kind of contactless force; Therefore the situation that external magnet can not effectively drive the motion of internal cleaning spare just might occur, particularly more when obturator, obstruction is comparatively " closely " time; Occur this situation especially easily, at this moment, the drain function of drainage tube will be affected; Even forfeiture, crisis patient life; Secondly be exactly, the Magnet volume of drainage tube inside is bigger, and the internal diameter of original drainage tube was just limited, and the big volume of inner magnet has further occupied the inner volume of drainage tube, has caused the reduction of drainage tube drain function on the contrary; Be exactly once more, this structural design cost is higher, also is a kind of extra burden for patient.Therefore we are to 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
