Description
Technical field
This utility model is related to technical field of medical equipment, more particularly, to a kind of Non-heparin hemodialysis blood vessel.
Background technology
The mainstream therapies releasing edema at present are dialysed for extracorporeal blood：The blood of in patient body is extracted out, saturating through in vitro
The filtration of desorption device, the excessive moisture in blood is filtered, and the remaining blood through " concentration " feeds back in vivo, thus reaching releasing again
The purpose of edema.Hemodialysis are also the normal for the treatment of acute and chronic Delayed graft function (uremia) and acute drugs poisoning and pesticide intoxication
Use method.At present China has up to ten million Chronic Renal Failure Patients to need to sustain life with conventional hemodialysis (CHD) every year, and have by
The trend that year increases.Hemodialysis principle：Dialysis refers to that the solution of semipermeable membrane both sides passes through disperse, infiltration and Ultrafiltration, that is,
Solute is by the low side flowing of the high lateral concentration of concentration, and the high side of a lateral osmotic pressure that hydrone is forced down by infiltration
The process of flowing, is finally reached dynamic equilibrium.Hemodialysis are reached by the solution disperse between blood and dialysis solution and ultrafiltration
To therapeutic purposes.
Hemodialysis are primarily present following shortcoming：External due to extracting blood out, then feed back in patient body, blood
Can flow a period of time in vitro.With the prolongation of blood flowing time in vitro, blood easily solidifies in vitro, especially warp
It is easier in Non-heparin hemodialysis blood vessel during crossing the blood backflow into the human body after the dialysis of extracorporal dialysiss equipment
Middle solidification, thus causing bloody path blockage, now, not only needs again to replace duct of Arantius and arterial thus causing resource wave
Take, and certain threat can be caused to the life and health of patient.
In view of this it is necessary to be improved to Non-heparin hemodialysis blood vessel of the prior art, on solving
State problem.
Utility model content

For achieving the above object, this utility model provides a kind of Non-heparin hemodialysis blood vessel, including arterial
And duct of Arantius；Described arterial includes several tremulous pulse arms that tremulous pulse house steward connected with tremulous pulse house steward and clamping tremulous pulse props up
The holder of pipe, tremulous pulse kettle that described tremulous pulse arm is connected, described tremulous pulse kettle is provided with two exhaust heads, sets in described tremulous pulse kettle
There is drainage screen；Described duct of Arantius includes several vein arms and the clamping venous branch that vein house steward is connected with vein house steward
The holder of pipe, venous chambers that described vein arm is connected, described venous chambers are provided with exhaust head and air detection head, described quiet
It is provided with drainage screen in arteries and veins kettle.
In some embodiments, described drainage screen is provided with filtering holes.
In some embodiments, generally circular in shape, the oval, rectangle of described filtering holes or rhombus.
In some embodiments, described drainage screen is in parallel arrangement in tremulous pulse kettle and/or venous chambers.
In some embodiments, described drainage screen is in non-parallel arrangement in tremulous pulse kettle and/or venous chambers.
In some embodiments, described holder is collet or elastic cord.
Compared with prior art, the beneficial effects of the utility model are：Tremulous pulse arm is optionally clamped by holder
With vein arm, such that it is able to independently select blood circulation passage, effectively prevent blood vessel and block because of blood coagulation,
So that the blood after dialysis can swimmingly flow back into the human body, improve the safety coefficient of Non-heparin hemodialysis.

Specific embodiment
Shown each embodiment is described in detail to this utility model below in conjunction with the accompanying drawings, but it should explanation,
These embodiments are not limitation of the utility model, and those of ordinary skill in the art are according to these embodiment institute works
Equivalent transformation in energy, method or structure or replacement, belong within protection domain of the present utility model.
A kind of Non-heparin hemodialysis blood vessel as shown in Figure 1, Figure 2 and Figure 3, including duct of Arantius 100 and arterial
200.Duct of Arantius 100 and arterial 200 are rubber hose.This duct of Arantius 100 can be joined with extracorporal dialysiss equipment with arterial 200
Close and use, to form a blood circulation passage.
Described duct of Arantius 100 include vein arm 11 that vein house steward 1 connected with vein house steward 1 and vein arm 12 with
