Abstract
The invention relates to an aorta intubation tube. The main body of the aorta intubation tube is a composite reducer pipe, and an intubation chew formed by bending a right angle is arranged at one end of which the diameter is smaller. The intubation tube is characterized in that a through hole is formed in a right angle bending back, and an one-way valve through which blood can flow from outside to inside is mounted on the through hole. According to the invention, the through hole with the one-way valve is arranged in the right angle bending back of the intubation tube, so that the condition that after an external circulation aorta intubation tube is set in a baby without external circulation, the heart of the baby can enable the blood to flow easily and smoothly to an aorta, is ensured, and then, the blood is distributed to the whole body to provide required oxygen and nutrient substances, and maintain the stability of blood pressure and hemodynamics; when the external circulation begins and during the external circulation, along with the rising of the pressure in the aorta intubation tube, the one-way valve at the through hole generates functional closing, so that the condition that the blood flows to the far end of the aorta to discharge blood, and the blood does not return to the heart is ensured.
Description
Technical field:
The invention belongs to technical field of medical instruments, particularly relate to the special aortic cannulation of a kind of infant.
Background technology:
Along with the progress of society, the reach of science, most children with CHD all will carry out operative treatment in infant period.Infant heart is little, and blood vessel is thin, and the conventional aortic cannulation of application, after setting up extracorporeal circulation intubate, easily causes heart smooth to aorta row blood, so that blood pressure drops and affect hemodynamic stable.For overcoming above-mentioned drawback, the unit in the past had attempts to set up extracorporeal circulation with thinner aortic cannulation, but this may occur high pump pressure, is even forced to interrupt extracorporeal circulation.
Aortic cannulation is one of required material of open-heart surgery, and the aortic cannulation designed according to various operation is providing a great convenience for carrying out of operation on vessels of heart.But the conventional aortic cannulation of the many employings of infant operation on heart aortic cannulation at present, be also elbow bend intubate, in process of clinical application, there are the following problems: after 1, inserting, elbow back easily causes heart not smooth to aorta row blood; 2 and to insert aorta comparatively dark, also easily cause heart not smooth to aorta row blood.
How to improve the deficiency of existing aortic cannulation, namely become the object of the present invention's research.
Summary of the invention:
The object of the invention is design one and offer through hole at quarter bend back of the body place, and the aortic cannulation of unidirectional nest lobe is installed on through hole.
Technical solution of the present invention is achieved in that a kind of aortic cannulation, main body is a compound reducer pipe, the intubate that the less one end of diameter has right-angle bending and formed is chewed, it is characterized in that: at the quarter bend back of the body, place offers a through hole, this through hole is provided with blood can from the outer unidirectional nest lobe toward interior flowing.
Described through hole is opened in the center position of the quarter bend back of the body.
Described through hole is the long axis direction of slotted eye, this slotted eye, parallels with the axis of compound reducer pipe; It is suitable that the width of through hole and intubate chew diameter, and the length of through hole is the twice of width.
The present invention sets up the through hole being with unidirectional nest lobe at intubate quarter bend back of the body place, can ensure after infant sets up extracorporeal circulation aortic cannulation, and when not carrying out extracorporeal circulation, heart is unobstructed to aorta row blood, then whole body is distributed to, to provide required oxygen and nutrient substance, maintain blood pressure and hemodynamic stable; When extracorporeal circulation starts and period, along with pressure in aortic cannulation raises, the unidirectional nest lobe generating function of through hole is closed, ensures that blood flow arranges blood to distal aorta, and the heart that can not backflow.
Accompanying drawing illustrates:
Below in conjunction with concrete legend, the present invention will be further described:

Fig. 2 aorta blood flow schematic diagram
Wherein
1-intubate chews 2-quarter bend back of the body, 3-through hole, 4-unidirectional nest lobe
Detailed description of the invention:
With reference to Fig. 1, a kind of aortic cannulation, main body is a compound reducer pipe, the intubate that the less one end of diameter has right-angle bending and formed chews 1, and carrying on the back 2 places at quarter bend offers a through hole 3, and this through hole 3 is provided with blood can from the outer unidirectional nest lobe 4 toward interior flowing.Described through hole 3 is opened in the center position of the quarter bend back of the body 2, and this through hole 3 is the long axis direction of slotted eye, this slotted eye, parallels with the axis of compound reducer pipe, that is forms plane parallel with compound reducer pipe inner blood flow direction; It is suitable that the width of through hole 3 and intubate chew 1 diameter, and the length of through hole 1 is the twice of width.
The present invention relates to unidirectional nest lobe 4, namely check valve, only allow blood to chew in 1 from export-oriented intubate and flow into, guarantee heart is unimpeded to aorta row blood, and intubate aorta posterior blood flow is as Fig. 2 arrow.
Claims (3)
1. an aortic cannulation, main body is a compound reducer pipe, and the intubate that the less one end of diameter has right-angle bending and formed is chewed, and it is characterized in that: offer a through hole at quarter bend back of the body place, this through hole is provided with blood can from the outer unidirectional nest lobe toward interior flowing.
2. a kind of aortic cannulation according to claim 1, is characterized in that: through hole is opened in the center position of the quarter bend back of the body.
3. a kind of aortic cannulation according to claim 1 and 2, is characterized in that: through hole is the long axis direction of slotted eye, this slotted eye, parallels with the axis of compound reducer pipe; It is suitable that the width of through hole and intubate chew diameter, and the length of through hole is the twice of width.
