Abstract
The utility model relates to an artery intubation used in cardiopulmonary bypass heart direct vision operations, and the intubation head of the present artery intubation is a single-hole type, and the design is not perfect, and the resistance is big when bloods pass through, and the damage to blood ingredients and the artery veins is big, and the utility model is not easy in use and is bad in patients safety. The utility model is formed by connecting a joint with a socket through a pipe body, and the lateral walls of the socket are provided with lateral holes for blood flowing out, and a front port plugged inner cavity is a cone shape, and the effect of the utility model is that the bloods shunt evenly, and the resistance is reduced when bloods pass through, and the damage to blood ingredients and the artery veins is small, and the front port plugged inner cavity is a cone shape, of which is convenient in intubation and the cardiopulmonary bypass safety can be improved.
Description
One, affiliated technical field
This utility model relates to a kind of arterial cannulation of using when being used for open heart operation with extracorporeal circulation.
Two, background technology
At present, in open heart operation with extracorporeal circulation, venous blood becomes arterial blood by outside the venous cannulation lead body behind the artificial lung oxygenate, through the artificial heart arterial blood is failed the Huis' body intra-arterial through arterial cannulation again, thus the whole process of perfect aspect outer circulation.Used its intubate head of arterial cannulation is a monotrysian type at present, and this design is perfect not to the utmost, and resistance was big when blood passed through, and is bigger to blood constituent destruction, big to the damage of arterial blood tube wall, uses inconvenience, to the patient safety poor performance.
Three, summary of the invention
Order of the present utility model ground is to overcome the deficiencies in the prior art, and a kind of novel arterial cannulation of using when open heart operation with extracorporeal circulation is provided.Reach its blood constituent is destroyed less, little, easy to use to the damage of arterial blood tube wall, improve patient's safety.
Order of the present utility model ground is realized with following proposal:
Arterial cannulation is made up of 2 connecting pins 1 of joint 3 process bodys, and joint 3 other ends are connected with external arterial blood feeder vessels, it is characterized in that: plug 1 its sidewall has 2-4 the side opening 7 that flows out blood, and prosopyle shutoff inner chamber is cone-shaped 6.
Described arterial cannulation is characterized in that: be useful on deflated side opening 4 on the joint 3.
Described arterial cannulation is characterized in that: body 2 inner arms assembling supporting steel wire 5.
Described arterial cannulation is characterized in that: plug 1 is the straight peen form structure.
Described arterial cannulation is characterized in that: plug 1 is the elbow form structure.
Effect of the present utility model: its sidewall of the plug of arterial cannulation has a plurality of side openings, prosopyle shutoff inner chamber is cone-shaped, blood can only flow out by the side opening in the sidewall, blood shunt is even, blood by the time resistance reduce, blood constituent is destroyed less, little to the damage of arterial blood tube wall, intubate is convenient, improves patient safety.
Four, description of drawings
Describe this utility model embodiment in detail below in conjunction with accompanying drawing:
Fig. 1 is this utility model overall structure sketch map.
Fig. 2 is the structure for amplifying sketch map of Fig. 1 intercalation part.
Number in the figure explanation: 1. plug, 2. body, 3. joint, 4. steam vent, 5. steel wire, 6. block head, 7. areole.
Five, the specific embodiment
Referring to Fig. 1, arterial cannulation is made up of through body 2 patch plugs 1 joint 3.Joint 3 other ends are connected with external arterial blood feeder vessels, and the side opening 4 that joint 3 has is used for aerofluxus; Body 2 can divide strip steel silk 5 support types and two kinds of structures of strip steel silk 5 support types not; Plug 1 is the part of inserting in the arteries, can divide has straight peen form and elbow form structure, its angle any one numerical value between the 100-180 degree, and plug 1 sidewall has a plurality of side openings 7, prosopyle shutoff inner chamber is cone-shaped 6, and blood can only flow out by side arm hole 7.
Referring to Fig. 2, plug 1 its sidewall of arterial cannulation has a plurality of side openings 7, prosopyle shutoff inner chamber is cone-shaped 6, be used for shunting uniformly blood, blood can only flow out by the side opening in the sidewall 7, blood by the time resistance reduce, destroy less to blood constituent, little to the damage of arterial blood tube wall, intubate is convenient, improves patient safety.
