Abstract
The utility model discloses a venous tube used in department of cardiac surgery and relates to the technical field of medical devices used in the department of cardiac surgery. The venous tube adopts a hollow soft rubber tube, a lower umbrella-shaped ring with the bigger end in an upper position and the smaller end in a lower position is arranged at the lower end part of the tube, and an upper umbrella-shaped ring with the bigger end in a lower position and the smaller end in an upper position is arranged above the lower umbrella-shaped ring. The upper umbrella-shaped ring and the lower umbrella-shaped ring arranged at the lower end part of the venous tube are connected to form a shuttle shape, so as to reduce the in-out resistance force of a tube support, and improve the operation safety through preventing the doctor from tearing the vessel of patient when placing in or taking out the venous tube.
Description
Technical field
This utility model relates to the department of cardiac surgery technical field of medical instruments, relates in particular to a kind of department of cardiac surgery venous cannulation.
Background technology
In the clinical practice of cardiac operation, common by stages rescuing as congenital heart disease; Once more or the repeatedly bypass surgery of coronary atherosclerotic heart disease row coronary bypass; Change lobe or the capable valve replacement postoperative of valvular heart disease after the mitral stenosis row enclosed dilatation once more and valve occurs and damage, and the related complication of valve surgery and need carry out valve replacement surgery or the like once more.The patient of this class has extensive adhesion because heart had been accepted operation in the pericardial cavity, operation need be set up extracorporeal circulation once more.And once more or the repeatedly extracorporeal circulation of operation on heart, be a very thorny and dangerous job.For addressing the above problem, someone has done useful exploration and has proposed concrete technical scheme, disclosedly design on November 25th, 2009 as State Intellectual Property Office by Meng Qi, the patent No. is 200920019526.9, name is called the utility model patent of a kind of department of cardiac surgery with venous cannulation, its intubate is the flexible hose of a Gen Neitong, bottom in described intubate, be provided with the umbrella snare, the big end of described umbrella snare is last, the small end infra, can avoid extensively separating superior vena cava, postcava and right atrium as long as can see right atrium, can be cut an osculum at right atrium, intubate is inserted in the right atrium, further sent into caval vein again.At this moment, the umbrella snare can prop up the caval vein inwall in caval vein, thereby block venous blood flows into right atrium.Its shortcoming is: use the umbrella snare to be not easy to withdraw from after operation finishes as venacaval supporter, and umbrella snare edge is easy to generate turnup when withdrawing from, even causes tearing vein and cause that angiorrhexis causes massive hemorrhage.
Summary of the invention
The purpose of this utility model provides a kind of department of cardiac surgery venous cannulation safe and convenient to use.
The technical scheme that this utility model is adopted for achieving the above object is:
A kind of department of cardiac surgery venous cannulation, described intubate is the flexible hose of a Gen Neitong, the bottom of intubate is provided with big end at following umbrella snare last, the small end infra, it is characterized in that: the top of described down umbrella snare also is provided with big end infra, small end umbrella snare on last.
Department of cardiac surgery venous cannulation of the present utility model, the last umbrella snare that its bottom is provided with joins with following umbrella snare and is fusiformis, reduce the resistance of intubate supporter turnover, can make the doctor when placing and take out venous cannulation, prevent to tear patient's blood vessel, thereby improved the safety of operation.
Description of drawings
Accompanying drawing is the sketch map of a kind of department of cardiac surgery of this utility model with venous cannulation.
Among the figure: 1-intubate, umbrella snare under the 2-, the last umbrella snare of 3-.
The specific embodiment
Accompanying drawing is the sketch map of a kind of department of cardiac surgery of this utility model with a kind of specific embodiment of venous cannulation, this intubate is the flexible hose of a Gen Neitong, the bottom of intubate 1 is provided with big end at following umbrella snare 2 last, the small end infra, and the top of infra umbrella snare 2 also is provided with big end infra, small end umbrella snare 3 on last.
