A kind of breathing circuit
The present invention relates to a kind of medical instrument, more particularly to a kind of breathing circuit.
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.
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.
In order to achieve the above objectives, the technical solution adopted by the present invention is as follows：
A kind of breathing circuit disclosed by the invention, including breeches joint, air intake duct, exhaust tube, collecting bowl, the air-breathing
Pipe and exhaust tube are screwed pipe, and a branch pipe of air intake duct one end and breeches joint connects, the other end setting air-breathing of air intake duct
Pipe fitting, another branch pipe in described exhaust tube one end and breeches joint are connect, the other end setting expiration pipe fitting of exhaust tube, institute
It states there are two collecting bowls, two collecting bowls connect respectively with air intake duct and exhaust tube, the madial wall of the exhaust tube and air intake duct
The collecting gutter for directing water into collecting bowl is equipped with, the collecting gutter is axially disposed, and the bottom of collecting gutter is less than the spiral shell of screwed pipe
Further, the side wall stage casing of the exhaust tube and air intake duct is respectively equipped with sliding part, and the collecting bowl is with sliding
Portion is slidably matched, be axially arranged with seam of the sliding part along exhaust tube or air intake duct, and seam, the seam are passed through at the top of the collecting bowl
Equipped with concave convex button, both sides are respectively equipped with the cam being adapted to concave convex button and recessed button, collecting bowl top both ends at the top of the collecting bowl
It is respectively equipped with pull head.
Preferably, the collecting bowl top surface is diamond shape equipped with protrusion, the protrusion, and the recessed button is respectively provided at convex with cam
The both sides risen, two pull heads are respectively provided at the both ends of protrusion.
Preferably, the collecting bowl includes cup lid, cup body, and the cup lid is threadedly coupled with cup body, and the cup lid center is set
There is through-hole.
Further, the cup lid is equipped with the valve deck being adapted to through-hole, and the valve deck bottom is connect with strut, the strut
Through through-hole, convex eaves is equipped in the middle part of strut, spring is equipped between the convex eaves and cup lid, the length of the strut is more than cup body
Further, the valve deck is circular platform type, and valve deck base diameter is less than top diameter.
Preferably, the air intake duct side wall is equipped with branch pipe interface.
Preferably, the branch pipe interface is equipped with check valve.
Further, the branch pipe interface is located at breeches joint end.
Further, the cross section of the collecting gutter is isosceles triangle.
Preferably, the cup body is transparent material.
The invention has the advantages that：
1. the position that the present invention can adjust collecting bowl is always positioned at the lowest part of breathing circuit, ensure the receipts of condensed water
2. collecting gutter can make the remaining condensed water of the screwed pipe bottom of thread import movable part automatically, and then flow into and catchment
Cup avoids the residual of pipeline condensed water；
3. the connection mode of concave convex button can ensure the leakproofness of pipeline, and can realize the slip of collecting bowl；
4. collecting bowl is directly installed on breathing circuit, is connected without threeway, the connection of pipeline and threeway can be avoided
Coming off causes the accident；
5. the protrusion of diamond shape is conducive to unlatching and the closure of concave convex button, facilitate the slip of collecting bowl；
6. cup lid is threadedly coupled with cup body, facilitates and remove the condensed water of collection；
7. the cooperation of valve deck, strut, spring so that when cup body is connect with cup lid, through-hole is opened, and condensed water can flow into cup
Body, and when removing cup body, valve deck is automatically closed, and ensures the seal of pipeline；
8. the design of branch pipe interface can avoid Sucked medicine from polluting lung ventilator；
The seal of machine pipeline 9. the design of check valve can ensure respiration, while also be able to that condensed water is avoided to enter administration
10. cup body is transparent material, facilitate the amount of observation condensed water.
