Description
Technical Field
The utility model belongs to the technical field of medical device, more specifically say, when involving cardiac surgery and the surgery operation under the extracorporeal circulation, guarantee unobstructed, safe drainage tubular product of left heart drainage.
Background
Extracorporeal circulation (extracorporeal circulation): the life support technology comprises the steps of utilizing a series of special artificial devices to drain cardiovenous blood to the outside of a body, carrying out gas exchange by an artificial method, adjusting temperature, filtering and then returning the blood to an internal arterial system. Is a life support device for heart surgical valves, congenital heart disease, large blood vessels and partial bypass operations, and plays an important role in the operation. Whether each device in the extracorporeal circulation is successful or not is directly related to the success or failure of the experiment. The left heart drainage tube commonly used in clinic at present has many defects: the opening of the tube wall is unreasonable, and the suction port without a protective device is easy to cause the blockage of the blood inflow port due to the absorption of the drainage tube to the endocardium caused by negative pressure in the drainage process; no fixing device is arranged after the implantation, so that the tube is easy to fall off; the left heart pipe trunk has no buckle device, which easily causes the air to flow back into the heart.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the prior art, the utility model provides a novel air bag left heart drainage tube, which solves the problem that the left heart tube repeatedly adsorbs endocardium to cause blockage in the extracorporeal circulation of the prior art.
The technical scheme of the utility model is that:
the utility model provides a novel gasbag left heart drainage tube, includes left heart pipe trunk, has set gradually card pressure formula switch, inflation connecting pipe, activity double wing fixing device and side suction hole on the left heart pipe trunk, and inflation connecting pipe communicates with each other with distal end inflation cuff through tubule of left heart pipe trunk lateral wall, and the side suction hole runs through left heart pipe lateral wall, and inflation cuff sets up on the left heart pipe trunk of side suction hole periphery.
The movable double-wing fixing device comprises a sleeve sleeved on the main stem of the left heart pipe, and double wings which can be movably adjusted are arranged at two ends of the sleeve.
The other end of the inflation connecting pipe is connected with an indication saccule.
The side suction holes are three rows and are uniformly distributed on the periphery of the left heart pipe.
The number of the inflatable cuffs is three, the inflatable cuffs and the side suction holes are arranged at intervals, and the near-vitro circulation end of the inflatable cuff is communicated with the inflatable connecting pipe and the three inflatable cuffs.
The utility model discloses beneficial effect:
the utility model discloses the device can form complete and safe left heart drainage pipe device, can in time adjust the switching of left heart pipe as required, guarantees that the drainage tube is unobstructed, avoids adsorbing with the endocardium.
Compared with the left heart tube commonly used in the existing clinic, the utility model provides a controllable switch device to ensure the safety of opening and closing and prevent air and the like from entering the heart; meanwhile, the side air bag is combined with the supporting effect, so that the blockage caused by the adsorption of the side suction hole and the endocardium can be effectively avoided.
The utility model discloses can realize the left heart drainage better and save operation time, alleviate the operation risk, easy operation can effectively avoid left heart pipe and tissue to adsorb, for it is unobstructed to provide the drainage in the extracorporal circulatory system operation patient art, has guaranteed critical patient's safety.

Detailed Description
In order to explain the present invention more clearly, the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1: the utility model discloses gasbag left heart drainage tube includes left heart pipe trunk 1, and card pressure formula switch 2 is located before the left heart union coupling negative pressure device, can keep opening and closing as required, and prevention air bubble etc. get into the heart. The inflation connecting pipe 4 is used for ventilating through a thin pipe on the side wall of the left heart pipe main body 1 (the thin pipe is arranged in the middle of the pipe wall), and is finally communicated with the far-end inflation cuff 6, the other end of the inflation connecting pipe is connected with the indicating saccule 3, so that the pressure of the cuff implanted into the heart and the supplement pressure when necessary are monitored, and the inflation cuff is guaranteed to play a supporting role all the time. The movable double-wing fixing device 5 comprises a sleeve sleeved on the main stem of the left cardiac tube, and two movably adjustable double wings are arranged at two ends of the sleeve so as to be strictly fixed at the wall end of a blood vessel after being implanted into the heart and ensure the safety of preventing the tube from being detached. As shown in figure 2, the side suction holes 7 are three rows and penetrate through the side wall, so that blood outside the tube is sucked into the inner cavity, and the side suction holes are uniformly distributed on the periphery of the left heart tube. The lateral suction hole is added, and the lateral suction hole is kept smooth through the support of the air bag. The number of the inflatable cuffs is three, the inflatable cuffs and the side suction holes are arranged at intervals, and the near-vitro circulation end of the inflatable cuff is communicated with the inflatable connecting pipe and the three inflatable cuffs.
The utility model discloses during the use, mainly include following step:
(1) a big mattress type suture is made at the root part of the right upper pulmonary vein and the connecting part of the left atrium, the purse string suture is carried out by using a placian thread, the heart inlet end of the left cardiac tube is punctured by a sharp knife and inserted into the left atrium, the purse string is tightened, and the double wings are fixed on the pulmonary vein by using a thin blocking tube to ensure the firmness.
(2) The inner core of the left heart tube is taken out, and the main stem clamping-pressing type switch of the left heart tube is closed to ensure the closing of the left heart tube.
(3) And connecting an extracorporeal circulation negative pressure device, inflating the indicating saccule end injector, and adjusting pressure change according to the indicating saccule condition.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention.
