Abstract
The utility model relates to a reverse-filling tube for coronary venous sinus. A tube body is divided into three chambers, wherein, a big chamber at the middle part is a filling chamber, a small chamber at the upper part is a pressure-measuring chamber, and a small chamber at the lower part is a saccule-inflating chamber. A saccule is arranged at the tube body near an inserted end and a filling hole is arranged on a tube wall connected with the saccule. An opening at one end of the pressure-measuring chamber is filled with the inserted end of the tube and a side hole is arranged at the filling chamber near the inserted end. Each chamber is respectively connected with a filling device, a pressure monitoring device and a gas charging valve by a connecting tube and a tube base. A steel wire reinforcement lining is arranged inside the tube wall to prevent the filling tube from being deformed after being compressed and bent and ensure the pipeline of each chamber clear. The utility model has the advantages of one tube with multi-function, squeezing-proof quality, bending resistance, good flexibility, convenient operation and easy control, and therefore, has a wide development prospect in medical catheters.
Description
This utility model relates to a kind of medical catheter, particularly a kind of retrograde coronary sinus perfusion pipe.
At present, mostly be expressing technique molding etc. greatly through continuous conduit what the clinical external cardioplegic solution perfusion that is used for diffusivity coronary atherosclerosis and aortic valve surgical patient of medical field was used, it is poor not to be provided with the anti-extruding of steel wire reinforcing line pipeline in it, easily bending, and cause pipeline not smooth, in operation, produce accident easily, bring unnecessary misery to patient.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and the retrograde coronary sinus perfusion pipe of a kind of anti-extruding, bend resistance is provided.
This utility model is realized by following measure:
The retrograde coronary sinus perfusion pipe is to be made of body, connection base, connection tube and base etc., be designed to 3 independently chambeies in the body, chamber broad in the middle is a filling cavity, the top loculus is a pressure measuring cavity, the bottom loculus is the balloon inflation chamber, be provided with sacculus in body near an end, a steel wire reinforcing line also is set in tube wall, it is not isometrical that pipe diameter is.
And have a full hole on the tube body wall of sacculus connecting part.Filling cavity has a side opening near position, an end, and pressure measuring cavity one end opening is in the body insertion end.
Description of drawings:
Fig. 1 is an overall structure sketch map of the present utility model;
Fig. 2 is this utility model body A-A cutaway view.
Below in conjunction with accompanying drawing this utility model is described further:
The retrograde coronary sinus perfusion pipe as depicted in figs. 1 and 2, be to constitute by body 2, connection base 4, connection tube 5,6,7 and base 9,10 etc., be designed to 3 chambeies in the body, chamber broad in the middle is that filling cavity 11, top loculus are the pressure measurement accent, the bottom loculus is balloon inflation chamber 13, and filling cavity 11 front end positions have a side opening 15, is provided with sacculus 1 near side opening 15 positions, filling cavity directly is opened on the body insertion end, and the other end is connected with device for casting with base 10 by connection tube.Pressure measuring cavity 12 1 end openings 16 are in insertion end, the other end is connected with the contrary pressure monitoring device of irritating with base 9 by connection tube 5, have a full hole 14 on the tube body wall of balloon inflation chamber 13 and sacculus connecting part, its sacculus is manual swelling bag, after sacculus is full the intrusion pipe insertion end is sealed in the coronary sinus vein place, balloon inflation chamber one end is connected with charge valve 8 by connection tube 7.Be provided with the steel wire reinforcing line between tube wall and three chambeies, the conduit insertion end is inserted human body because of need, and its diameter is less, and connecting line need be distinguished in each chamber of the other end, and for guaranteeing that pipeline is unobstructed and be easy to processing, its diameter is a bit larger tham the insertion end diameter.
The utility model has the advantage of according to clinical use needs, body is designed to three chambeies, can be respectively applied to sacculus Dilate, perfusion and pressure measurement, sacculus is safe and reliable, owing to add the steel wire reinforcing line in body, makes the anti-extruding of conduit. Bend resistance has again pliability, can guarantee to pour in the operation and carry out smoothly.
