Description

A kind of breathing circuit
Technical field
The present invention relates to a kind of medical instrument, more particularly to a kind of breathing circuit.
Background technology
During medical rescue, often patient is helped to carry out assisted respiartion using lung ventilator, and lung ventilator is using In process, condensed water can be generated in breathing pipeline, the condensed water of aggregation can not only influence the conveying of oxygen, if condensed water is suitable The respiratory tract that pipeline enters patient, can cause to have difficulty in breathing and then brings danger to patient.
To solve the problems, such as this, at this stage, the air inlet pipe of breathing pipeline carrys out collecting pipe with setting collecting bowl in the middle part of air outlet pipe Condensed water in road, however in use, since the position of collecting bowl is fixed, usually because collecting bowl is not located in The lowest part of pipeline, and condensed water is caused to enter the respiratory tract of patient along pipeline without inflow collecting bowl in time, cause disease People's expiratory dyspnea is even blocked.
In addition, since collecting bowl is connected in breathing circuit by threeway, when receiving external force, three-way connection is easy It comes off, causes the accident.
And some patients need to carry out drug Inhalation in Treating while assisted respiartion, if drug added through lung ventilator Enter into breathing circuit, be easy to cause lung ventilator internal contamination and even damage.
In order to increase condensation effect enlarged contact face, present breathing circuit is screwed pipe, however each screw thread bottom Portion can all remain a part of condensed water, and remaining condensation dilutional hyponatremia also easily enters the respiratory tract of patient along pipeline, causes disease People's expiratory dyspnea is even blocked.In actual mechanical process, medical staff needs timing jitter or erects breathing circuit discharge The remaining condensed water of the bottom of thread, not only increases the workload of medical staff, also there are some potential safety problemss.
Invention content
The present invention is intended to provide a kind of breathing circuit, the position that can adjust collecting bowl is always positioned at breathing circuit Lowest part ensures the collection of condensed water;And pipeline can be avoided to be broken off;Sucked medicine pollution breathing can be avoided simultaneously Machine;It is also avoided that bottom of thread remaining condensed water, condensed water can be allowed all to flow into collecting bowl.
