Abstract
A kind of breathing circuit filter, it comprises: " └ " type first interface, the second interface, housing, filter course; Be formed with spatial accommodation in housing, filter course to be arranged in spatial accommodation and to be divided into two by the spatial accommodation in housing; " └ " type first interface is arranged on the first side of housing, for being connected with tracheal intubation; Second interface is arranged on the second side of housing, for being connected with respirator by pipeline; Described " └ " type first interface is connected with the first side of described housing integratedly by bellows.
Description
Technical field
This utility model relates to a kind of breathing circuit filter, particularly relates to a kind of breathing circuit filter that can possess Telescopic in the coupling part with tracheal intubation.
Background technology
Breathing circuit filter is usually used between tracheal intubation and respirator.In order to reduce the existence of air flue " dead space " as far as possible, the length that breathing circuit filter accounts in whole gas circuit is as far as possible little, and this also just makes breathing circuit filter be close to the connector of tracheal intubation.Be illustrated in figure 1 existing breathing circuit filter, directly and the interface grafting of tracheal intubation.But consider filter efficiency, filter area must ensure, this just makes breathing circuit filter form larger volume, is generally oblate spheroid shape.The incision of trachea of the breathing circuit filter patient proximate of larger volume, forms very large interference to other operations near cervical region, very inconvenience.Sometimes cause endotracheal tube warpage and affect in art ventilate for better exposing operating field and pushing endotracheal tube and breathing circuit filter.
Utility model content
In order to solve the problem, this utility model is intended to propose a kind of breathing circuit filter that can stretch with the coupling part of tracheal intubation.
Breathing circuit filter of the present utility model comprises " └ " type first interface, the second interface, housing, filter course; Be formed with spatial accommodation in housing, filter course to be arranged in spatial accommodation and to be divided into two by the spatial accommodation in housing; " └ " type first interface is arranged on the first side of housing, for being connected with tracheal intubation; Second interface is arranged on the second side of housing, for being connected with respirator by pipeline; Described " └ " type first interface is connected with the first side of described housing integratedly by bellows.
Preferably, described " └ " type first interface has through hole on the side that its tracheal intubation mouth is relative, and described through hole is removably by plug closes.
Preferably, the periphery of described through hole is formed by elastomeric material, can become large to make described through hole.
Preferably, the diameter of described through hole is 3mm.
Owing to adopting bellows with the connecting portion of tracheal intubation, under conventional sense, bellows is shunk, and farthest ensures that " dead space " is less.When needs implement treatment or inspection at cervical region, when needing the interference getting rid of breathing circuit filter, bellows is stretched, makes it to be in the state away from tracheal intubation, for space is won in operation and inspection operation.Operation and inspection operation shrink bellows after implementing, and make it to restore to the original state.In addition, " └ " type first interface is conducive to the trend changing air flue pipeline.
Corrugated tube and filter integrated design, can reduce the connector in two place's breathing circuits, thus reduce the uncoupling phenomenon generation performing the operation or operate the breathing circuit that tractive causes, and improves safety, more valuable when prone position operation.

Detailed description of the invention
Below, composition graphs 2-5 is described in detail to this utility model.
Breathing circuit filter comprises " └ " type first interface 1, second interface 5, housing 3, filter course 4.
Be formed with spatial accommodation in housing 3, filter course 4 to be arranged in spatial accommodation and to be divided into two by the spatial accommodation in housing 3.
" └ " type first interface 1 is arranged on the first side of housing 3, for being connected with tracheal intubation." └ " type first interface 1 is connected with the first side of housing 3 integratedly by bellows 2.
Second interface 5 is arranged on the second side of housing 3, for being connected with respirator by pipeline.
Under general state, in order to ensure that " dead space " is as far as possible little, breathing circuit filter remains retracted state, as shown in Figure 2.
When needs implement operation or other operations to cervical region, in order to reduce the interference of breathing circuit filter, stretching breathing circuit filter makes it to keep extended state, thus away from tracheal intubation and cervical region, as shown in Figure 3.Breathing circuit filter is returned to the state of Fig. 2 after implementing by operation or other operations.
Through hole 7 is for fiberoptic bronchoscopy, and branchofiberoscope is inserted by this through hole 7, is convenient to can keep respirator normal operating conditions when needing in art to carry out fiberoptic bronchoscopy, can normal ventilation oxygen supply during ensureing operation.The diameter of through hole 7 is preferably 3mm.When not using, this through hole 7 is closed by stopper 6.Peripheral part of through hole 7 can adopt rubber or silica gel elastomeric material to make, and through hole 7 in use can elasticity be expanded, closely to insert branchofiberoscope.
