Transplantation accounts for the ratio of half.
At present in not stop jumping CABG, the coronary artery bypass device mostly external import for being used,
Not only use cost is higher, and this kind of current divider also has the following disadvantages：(1) shunting bolt two terminal circle is blunt and compares main diameter
Greatly, there is a problem of inserting difficulty；(2) quality is excessively soft, it is not easy to be inserted into slightly narrow Ink vessel transfusing.
Utility model content
The utility model is solved the above problems by providing a kind of coronary artery bypass device with inflatable bladders.
The utility model employs following technical scheme：
The coronary artery bypass device that the utility model is provided, has the feature that, including：Insertion bar portion, in hollow form,
Two ends are insertion end；Cuff portion, with two cuffs, two cuffs are respectively set on two outer walls of insertion end；
And charging portion, it is connected with cuff portion, for being inflated to cuff portion, it is in contact with the inwall of blood vessel after allowing it to expand,
So that the blood flow at this is circulated by inserting bar portion.Wherein, charging portion includes inflation unit and gas-conducting cells, and inflation unit is set
Put in vitro, for being filled with air to gas-conducting cells；In a tubular form, two ends are connected gas-conducting cells with two cuffs respectively, middle
Part is connected with inflation unit, for directing the air into cuff in.
The coronary artery bypass device that the utility model is provided, also has the feature that：Charging portion also includes buffer cell,
The buffer cell is in hollow cryptomere, and one end is connected with gas-conducting cells, and the other end is connected with inflation unit.
The coronary artery bypass device that the utility model is provided, also has the feature that：Cuff portion and buffer cell are adopted
It is made of soft rubber material.
The coronary artery bypass device that the utility model is provided, also has the feature that：Insert the external diameter of bar portion for 2~
3mm。
Utility model is acted on and effect
According to the coronary artery bypass device that the utility model is provided, because insertion bar portion is stereoplasm tube, the insertion end at two ends
Outer wall on be respectively arranged with two cuffs, two cuffs are connected by gas-conducting cells with inflation unit, insertion need
Before the blood vessel for being shunted, cuff portion can be in that flat shape is attached on the outer wall of insertion bar portion, after Ink vessel transfusing is inserted, cuff portion
Can be expanded by inflation and then be in close contact with blood vessel so that blood is flowed by inserting bar portion so that this practicality is new
The external diameter of the insertion bar portion of the coronary artery bypass device of type can suitably reduce, and facilitate inserting and extracting out for insertion bar portion.
Brief description of the drawings
Fig. 1 is the structural representation of the coronary artery bypass device in the utility model embodiment.
Specific embodiment
Specific embodiment of the present utility model is illustrated below in conjunction with accompanying drawing.
Embodiment one
Fig. 1 is the structural representation of the coronary artery bypass device of the present embodiment.
As shown in figure 1, coronary artery bypass device 100 includes insertion bar portion 1, cuff portion 2, charging portion 3.
Insertion bar portion 1 is stereoplasm tube, and two ends are respectively insertion end 11 and insertion end 12.
In the present embodiment, the external diameter of insertion bar portion is 2~3mm, is made of polypropylene or polyethylene.
Cuff portion 2 includes cuff 21 and cuff 22, is separately positioned on the outer wall of insertion end 11 and insertion end 12.
Charging portion 3 includes inflation unit 31, buffer cell 32 and gas-conducting cells 33.Inflation unit 31 by air pressure valve and
Caisson is connected；The one end of buffer cell 32 is connected with inflation unit, and the other end is connected with gas-conducting cells 33.
Buffer cell 32 is also cuff, and one end is connected by tubule and air pressure valve, the centre of the other end and gas-conducting cells 33
Part connects.Gas-conducting cells 33 are arranged in insertion bar portion, and two ends are connected with two cuffs respectively, center section and inflation
Unit is connected, for directing the air into cuff in.
In the present embodiment, buffer cell and cuff portion are made of soft rubber.
The application method of the coronary artery bypass device 100 in the present embodiment is as follows：
Insertion bar portion 1 and cuff portion 2 are first inserted into Ink vessel transfusing；Then air pressure valve is opened, the air after filtering passes through
Buffer cell 32 and inflation unit 33 enter it is inflated in cuff 21 and cuffs 22 respectively, two cuff portions inflations
Afterwards, the inwall of its outer wall and blood vessel is in close contact, and is supported on blood vessel so that blood is flowed into insertion rod portion, and cannot
Flowed out from otch；Finally air pressure valve is closed so that buffer cell 32 and cuff portion 2 keep inflated condition.
Because cuff portion 2 and buffer cell 32 are communicated, therefore the two air pressure is equal.Therefore, buffer cell 32 can react cuff
The pressure in portion 2, when gas is not fully filled in buffer part 3, illustrates the pipeline gas leakage between two cuffs, it is necessary to change coronary artery point
Stream device 100.After ventilation terminates, air pressure valve is opened, the gas in cuff portion 2 is extracted out, in order to by coronary artery bypass device
100 take out from narrow tracheae.
Embodiment is acted on and effect
According to the coronary artery bypass device that the present embodiment is provided, because insertion bar portion is stereoplasm tube, the insertion end at two ends
Two cuffs are respectively arranged with outer wall, two cuffs are connected by gas-conducting cells with inflation unit, need to entered in insertion
Before the blood vessel of row shunting, cuff portion can be in that flat shape is attached on the outer wall of insertion bar portion, after Ink vessel transfusing is inserted, cuff portion energy
It is enough to be expanded by inflation and then be in close contact with blood vessel so that blood is flowed by inserting bar portion so that the utility model
The external diameter of insertion bar portion of coronary artery bypass device can suitably reduce, facilitate inserting and extracting out for insertion bar portion.
The utility model is not limited to the scope of specific embodiment, for those skilled in the art, only
Want various change in claim restriction and the spirit and scope of the present utility model for determining, these changes are apparent
, all are using the innovation and creation of the utility model design in the row of protection.
