Description
Technical field
The utility model is related to medical instruments field more particularly to a kind of adherence hemodialysis conduits.
Background technology
Blood samples of patients is introduced into dialyzer by haemodialysis system, is expanded through infiltration using semipermeable membrane both sides solute concentration difference
Dissipate and ultrafiltration, reach and remove metabolite and toxicant, correct water, electrolyte balance disorder purpose.Haemodialysis
(hereinafter referred to as hemodialysis) includes renal replacement therapies, blood perfusion, immuno absorbence, Endotoxin adsorption and plasma exchange etc..It is each
Kind haemodialysis mode all respectively has feature, and is suitable for various disease and state, but no matter the hemodialysis of that type will be established
Arterial end blood introducing dialyzer is made blood purification by arteriovenous channel through Dialysis.Then again by the blood purified
It is fed back by vein end internal.Clinically common at present is a kind of foundation in the method progress arteriovenous channel that hemodialysis conduit punctures,
And hemodialysis catheter from lumen of artery draw blood carry out extracorporal dialysis when, due to suction function, vascular wall often adsorbs
It in lumen of artery bottom opening, is closed so as to cause lumen of artery bottom opening, leads to not draw blood and carry out extracorporal dialysis.
Utility model content
The utility model is intended to provide a kind of adherence hemodialysis conduit, can prevent hemodialysis conduit when hemodialysis from pasting
Wall, and two cavity length differences in hemodialysis conduit avoid artery from sucking blood influencing each other between vein blood back.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows：
A kind of adherence hemodialysis conduit, including Y tube body, the Y tube body include artery connecting tube, Connect of Vein pipe and
Tube chamber, the tube chamber include arterial lumen and vein tube chamber, and arterial lumen open top is connected to artery connecting tube, vein tube chamber
Open top is connected to Connect of Vein pipe；The arterial lumen is shorter in length than vein lumen length；Further include air bag, the air bag
On the upside of arterial lumen bottom opening and it is fixed on the tube wall where arterial lumen；The arterial lumen and artery connecting tube
Tube wall in be provided with gas passage, the one end open of the gas passage is connected to air bag, and another end opening of gas passage is located at
It is connected in artery connection pipe outer wall and with gas tube.
Preferably, partition board is equipped in the tube chamber, tube chamber or so is divided into arterial lumen and vein tube chamber by the partition board.
Preferably, the material of the Y tube body is medical plastic.
Preferably, the bladder shape is hemispherical.
Preferably, the vein lumen length is 20cm, and arterial lumen length is 16cm.
The utility model is simple in structure, easy to use.Hemodialysis conduit adherent blocking when can prevent hemodialysis, and
And two cavity length differences in hemodialysis conduit, avoid artery from sucking blood influencing each other between vein blood back.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In figure：1-Y shapes tube body, 2- arteries connecting tube, 3- Connect of Vein pipe, 4- tube chambers, 5- arterial lumens, 6- duct of Arantius
Chamber, 7- air bags, 8- gas passages, 9- gas tubes, 10- partition boards.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As shown in Figure 1, a kind of adherence hemodialysis conduit, including Y tube body 1, the Y tube body 1 include artery connecting tube
2, Connect of Vein pipe 3 and tube chamber 4, the tube chamber 4 include arterial lumen 5 and vein tube chamber 6,5 open top of arterial lumen with it is dynamic
Arteries and veins connecting tube 2 is connected to, and 6 open top of vein tube chamber is connected to Connect of Vein pipe 3；The arterial lumen 5 is shorter in length than duct of Arantius
6 length of chamber；Further include air bag 7, the air bag 7 is located on the upside of 5 bottom opening of arterial lumen and is fixed on 5 place of arterial lumen
On tube wall；Gas passage 8 is provided in the arterial lumen 5 and the tube wall of artery connecting tube 2, one end of the gas passage 8 is opened
Mouth is connected to air bag 7, and 8 another end opening of gas passage is located on 2 outer wall of artery connecting tube and is connected to gas tube 9.The pipe
Partition board 10 is equipped in chamber 4, tube chamber 4 or so is divided into arterial lumen 5 and vein tube chamber 6 by the partition board 10.The Y tube body 1
Material be medical plastic.7 shape of the air bag is hemispherical.6 length of vein tube chamber is 20cm, 5 length of arterial lumen
For 16cm.
In Clinical practice, the foundation in arteriovenous channel is carried out using the method that hemodialysis conduit punctures, then connects artery
It takes over and is connect respectively with haemodialysis control unit with Connect of Vein pipe, the blood of patient is entered from internal drainage in dialysis machine and is carried out thoroughly
Then blood backflow after dialysis is being entered patient's body, patient is made to complete dialysis treatment by analysis.Enter people when hemodialysis conduit punctures
When body blood vessel, the supravasal air bag of hemodialysis is inflated using gas tube, vascular wall is propped up in air bag expansion, keeps vascular wall separate
The bottom opening of arterial lumen avoids the effect due to vacuum suction that vascular wall is caused to be bonded arterial lumen, causes arterial lumen
Closure of openings.
The utility model is simple in structure, easy to use.Hemodialysis conduit adherent blocking when can prevent hemodialysis, and
And two cavity length differences in hemodialysis conduit, avoid artery from sucking blood influencing each other between vein blood back.
Certainly, the utility model can also have other various embodiments, without departing substantially from the spirit of the present invention and its essence
In the case of, those skilled in the art can make various corresponding change and deformations, but these phases according to the utility model
The change and distortion answered should all belong to the protection domain of the utility model the attached claims.
