Abstract
The utility model relates to a coronary venous sinus retrograde infusion tube, which comprises a tube body, a steel reinforced lining embedded in a tube wall of the tube body, connecting tubes, a tube seat, a check valve and an air bag. The coronary venous sinus retrograde infusion tube is characterized in that the tube body is a structure with unequal diameter; the smaller diameter end is an insertion one, and the larger diameter end is an external one; three independent cavities are arranged in the tube body, wherein the large cavity in the middle is an infusion cavity, one small cavity of the cavities is a pressure metering one, and the other small cavity is an air bag expanding one; the infusion cavity, the pressure metering cavity and the air bag expanding cavity of the tube body are respectively connected with the tube seat through the connecting tubes. The coronary venous sinus retrograde infusion tube has the advantages that the tube body is designed into three cavities respectively used for air bag expanding, infusion and pressure metering, and the air bag is safe and reliable, so as to realize multiple functions by one tube. The steel reinforced lining is arranged in the tube body, so that the infusion tube is resistant to extruding and bending and has the flexibility, and the intraoperative infusion is ensured to be performed smoothly.
Description
Technical field
This utility model belongs to clinical field of medical appliances, particularly a kind of retrograde coronary sinus perfusion pipe.
Background technology
At present, mainly contain the band reinforcing line and not with two kinds of structures of reinforcing line at this type of external cardioplegic solution intrusion pipe of China's clinical practice.The intrusion pipe of band reinforcing line is domestic still not to have production, is imported product, costs an arm and a leg; The intrusion pipe with reinforcing line mostly is not the isometrical continuous conduit of expressing technique molding greatly, and the anti-extruding of pipeline is poor, easily bending, and cause pipeline obstructed, and in operation, produce accident easily, bring unnecessary misery to patient.
Summary of the invention
This utility model provides a kind of extruding simple in structure, anti-, bend resistance and the low retrograde coronary sinus perfusion pipe of cost for solving the technical problem that exists in the known technology.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is: the retrograde coronary sinus perfusion pipe, comprise body, be inlaid in the air bag on steel wire reinforcing line, connection tube, base, check valve and close body one end in the body tube wall, it is characterized in that: described pipe diameter is not for waiting gauge structure, diameter is an insertion end than small end, the bigger end of diameter is external end, and described insertion end head takes the form of inclined plane; Be provided with 3 independently chambeies in the body, chamber broad in the middle is a filling cavity, and one of them loculus is a pressure measuring cavity, and another loculus is the air bag expanding cavity, and the filling cavity of described body, pressure measuring cavity are connected with base by connection tube respectively.
This utility model can also adopt following technical scheme:
Have a full hole on the sidewall of described body air bag expanding cavity.
Described body filling cavity has one group of side opening near the sidewall at insertion end position.
Described body pressure measuring cavity insertion end is open shape structure, and has a side opening on the pressure measuring cavity sidewall.
Advantage and the good effect that the utlity model has are: because this utility model adopts technique scheme, promptly, body is designed to three chambeies, can be respectively applied for that air bag dilates, perfusion and pressure measurement according to clinical use needs, airbag safety is reliable, realizes a tube multifunctional.Owing in body, add the steel wire reinforcing line, make the anti-extruding of intrusion pipe, bend resistance has pliability again, can guarantee to pour in the operation and carry out smoothly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1, body; 1-1, filling cavity; 1-1a, side opening; 1-2, pressure measuring cavity; 1-2a, side opening; 1-3, full chamber; 1-3a, full hole; 2, reinforcing line; 3, connection tube; 4, base; 5, check valve; 6, air bag.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the retrograde coronary sinus perfusion pipe comprises body 1, is inlaid in the air bag 6 on steel wire reinforcing line 2, connection tube 3, base 4, check valve 5 and close body one end in the body tube wall.Described pipe diameter is not for waiting gauge structure, and diameter is an insertion end than small end, and the bigger end of diameter is external end, and described insertion end head takes the form of inclined plane.Be provided with 3 independently chambeies in the body, chamber broad in the middle is filling cavity 1-1, and one of them loculus is pressure measuring cavity 1-2, and another loculus is air bag expanding cavity 1-3.Filling cavity directly is opened on the body insertion end, and the air bag expanding cavity is in the sealing of body insertion end, and the other end of described filling cavity, pressure measuring cavity is connected with base 4 by connection tube respectively.Have a full hole 1-3a on the sidewall of body air bag expanding cavity, air bag coats the full hole 1-3a of expanding cavity wherein.Sidewall at the close insertion end position of body filling cavity has one group of side opening 1-1a.Described body pressure measuring cavity insertion end is open shape structure, and has a side opening on the pressure measuring cavity sidewall.Steel wire reinforcing line 2 is embedded in the plastic tube body fully, in case intrusion pipe pressurized or bending after strain guarantee that each chamber is unobstructed.Described air bag is manual swelling bag, after air bag fills during use the intrusion pipe insertion end is sealed in patient's coronary sinus vein place, and the external end of air bag expanding cavity links to each other with check valve 5 by connection tube 3.
After air bag fills during use the intrusion pipe insertion end is sealed in patient's coronary sinus vein place, the external end of air bag expanding cavity links to each other with check valve 5 by connection tube 3.In the body tube wall, be provided with the steel wire reinforcing line, in case intrusion pipe pressurized or bending after strain guarantee that each chamber is unobstructed.The intrusion pipe insertion end enters human body because of need, and its diameter is less, and each chamber of external end need connect connection tube respectively, and for guaranteeing that pipeline is unobstructed and be convenient to processing, its diameter is greater than the insertion end diameter.
