Summary of the invention
The purpose of the present invention is to provide the liquid diverters that one kind can invert flow direction, convey liquid by the liquid diverter When, the liquid flow direction flowed out by tube body front end can be reversed.
To achieve the above object, the present invention uses following scheme: can invert the liquid diverter of flow direction, it has one section of pipe Body, the front end of tube body are connected with a coronal body, and medial surface, the lateral surface of coronal body are smooth curved surface, and tube body front end goes out It is mouthful opposite with the medial surface of coronal body, and between the front end of tube body and its two sides of front end and the medial surface of coronal body there are For the channel of liquid communication.
By above scheme as it can be seen that inputting the liquid of tube body by preceding when liquid diverter provided by the present invention conveys liquid After the outflow of end, by the blocking of coronal body, guidance, the flow direction of liquid can take a turn for the worse.It closes lung device in the external film of application and comes It realizes in the functional treatment of cardiopulmonary substitution when using, after being inserted into artery as arterial duct, may make from arterial duct to artery The blood flow flow direction that the blood flow direction of middle injection is projected with left ventricle is consistent, to break the limitation of " equalization point ", does not increase even Reduce the forward direction resistance of heart.
Structure of the invention rationally, reliable performance, its application range is wider, be especially suitable for using external film close lung device come It realizes in the treatment of cardiopulmonary substitution and is used as arterial duct.
Detailed description of the invention
Fig. 1 is the structural schematic diagram and use state diagram of the embodiment of the present invention one;
Fig. 2 is the portion the D enlarged drawing of Fig. 1;

Specific embodiment
With reference to embodiments and attached drawing further illustrates the present invention.
Referring to Fig. 1
The liquid diverter provided by the invention for inverting flow direction, it has one section of tube body 1, and the front end of tube body 1 is connected with One coronal body 2, medial surface, the lateral surface of coronal body 2 are smooth curved surface, the outlet and the inside of coronal body 2 of 1 front end of tube body Face is opposite, and there are for the logical of liquid communication between the front end of tube body 1 and its two sides of front end and the medial surface of coronal body 2 Road 5.
It is more smooth when to make liquid reversal of direction of flow, in the present embodiment, coronal 2 medial surface of body and 1 front end exit of tube body Baffle 2a with a protrusion on the position of alignment, the middle part of baffle 2a is in gradually crowned.
To make the substantially uniform-diameter of the outer diameter of coronal body 2 and tube body 1, in the present embodiment, the front end of tube body 1 is in Shape is gradually tapered up, the lower part of coronal body 2 is on the outside of the front end of tube body, between the front end of tube body 1 and the medial surface of coronal body 2 Several dowels 3 connect, and have the gap passed through for liquid between each dowel 3.
Referring to Fig. 1, Fig. 2
For the operation convenient for this liquid diverter when being placed in into artery, in the present embodiment, the middle part of coronal body is equipped with A half-duplex channel of its medial and lateral is penetrated through, which is the direction one-way conduction along coronal external side to inside.This implementation In example, the specific structure of half-duplex channel is that it has a conduit 6, and conduit 6 penetrates through coronal body 2, is hinged on the inner wall of conduit 6 One baffle 7 is equipped with spring 8 between the downside of baffle 7 and the inner wall of conduit 6.In addition, the baffle 7 in conduit 6 can also be by a check valve Substitution.When in conduit 6 by having object to pass through under upper, baffle 7 can be open, and conduit 6 is connected.
