Description
Technical field
The utility model relates to medical instruments fields, the specially a kind of two-way blood back hemodialysis pipeline of not termination of pumping.
Background technique
Haemodialysis is that chronic renal function failure patients rely one of essential therapeutic arsenals in existence for a long time, and operating method is
Achieve the purpose that remove vivotoxin and moisture by dialyzer using extracorporal circulatory system.In very long therapeutic process, Bing Renxu
Hospital is periodically arrived to carry out vascular puncture, establish the operation links such as extracorporal circulatory system, piping connection.The various dialysis of Blood Purification Center
Machine is using frequent, bed is intensive, patient's mobility is big, although taking personal management of staying in the ward to look after the patient night and day, the measures such as air sterillization,
The presence for having floatability dust particle is still difficult to avoid that in air, machine, treatment time in lower machine operation set especially on patient
Section, the content of microorganisms in air is compared with other periods height.In such a case, the polluted threat of operation every time of nurse.
Currently, its method of the hemodialysis pipeline of domestic each hospital's use are as follows: dialysis terminates-side pipe connection physiological saline-
Pump artery end-termination of pumping is fed back with blood pump strength, then is fed back again with blood pump strength with natural gravity return blood pump prerolandic artery Rolando end-
Artery end is pumped, dialysis filter-vein end-blood back finishes-extraction arterial needle and intravenous needle-hemostasis by compression respectively.This mode
Cannot direct closed circuit two-way blood back, when closed blood back, it is necessary to stop blood pump, arterial end blood is made to feed back body under the effect of gravity
Extracorporeal blood feedback is carried out after interior again, is easy to increase the generation of dialyzer blood coagulation；Nurse operation complex steps.
Utility model content
In view of the deficienciess of the prior art, the utility model aim be to provide one kind do not need termination of pumping operation, it is closed not
Meeting cross-infection, and the two-way blood back hemodialysis pipeline of not termination of pumping easily to operate.
To achieve the above object, the utility model provides the following technical solutions: a kind of two-way blood back hemodialysis pipeline of not termination of pumping,
Including arterial end, vein end, the arterial end passes through blood pump pipeline with vein end and is connected, and the front end on arterial end in blood pump is set
It being equipped with liquid supplementation pipe, the first pipe clamp is housed in liquid supplementation pipe, vein end is provided with filter in the rear end of blood pump, and its: the arterial end
It is connected between vein end by loop pipe；And third pipe clamp is housed in loop pipe.
Connection between the liquid supplementation pipe and arterial end, loop pipe and arterial end and vein end is to be sealed to connect by threeway
It is logical.
One end of the loop pipe is connected to the lower end of the liquid supplementation pipe on arterial end, and liquid supplementation pipe and loop pipe on arterial end
Between have the second pipe clamp；The other end of the loop pipe is connected to the lower end of the filter of vein end.
The threeway sealing connection position of the arterial end vein end has strainer.
Compared with prior art, the utility model has the beneficial effects that because the utility model is added to loop pipe, then dialyse
After by liquid supplementation pipe connect physiological saline using blood pump strength simultaneously feed back pump after dialyzer arterial end and vein end, return
The hemostasis by compression again of arterial needle and intravenous needle is extracted after blood respectively.It is not required to termination of pumping in the process, nurse operation is simple, and guarantees
The safety of patient.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of two-way blood back hemodialysis pipeline of not termination of pumping, packet
Arterial end 1, vein end 2 are included, the arterial end 1 passes through 3 pipeline of blood pump with vein end 2 and is connected, in blood pump 3 on arterial end 1
Front end is provided with liquid supplementation pipe 4, and first pipe clamp 8 is housed in liquid supplementation pipe 4, and vein end 2 is provided with filter 5 in the rear end of blood pump 3, and
It: being connected between the arterial end 1 and vein end 2 by loop pipe 6；And third pipe clamp 7 is housed in loop pipe 6.
One end of the loop pipe 6 is connected to the lower end of the liquid supplementation pipe 4 on arterial end 1, and on arterial end 1 liquid supplementation pipe 4 with
There is the second pipe clamp 10 between loop pipe 6；The other end of the loop pipe 6 is connected to the lower end of the filter 5 of vein end 2.Circuit
The setting of pipe 6 can effectively act as the effect that blood back is not termination of pumping.
The threeway sealing connection position of the arterial end vein end has strainer 9.Play the role of filtering, prevents microthrombus
Into internal.
In actual use, the distance between liquid supplementation pipe 4 and loop pipe 6 on arterial end 1 guarantee in energy the utility model
It is all right to put the second pipe clamp 10 into, generally also just between 5-10mm, can guarantee in this way it is pre- to rush the time short, it is more efficient.And liquid supplementation pipe 4
The control of the distance between pump front tube 9 is between 100-200mm.Liquid supplementation pipe described in the utility model and arterial end, loop pipe
Connection between arterial end and vein end is to be sealed to be connected to by threeway.
When the utility model at work: progress preliminary filling, pipeline are installed according to blood flow direction first, open the second pipe clamp 10
Afterwards, by the pre- made arterial line of gravity (at this time for rush the pipeline portions between liquid supplementation pipe and loop pipe in advance), it is then shut off
Two pipe clamps 10, blood pump is rushed in advance with 100ml/min frequency, and pipeline closes termination of pumping after third pipe clamp folder 7 after being full of salt water.Completely
After punching in advance, normal hemodialysis can be carried out, at this point, the first pipe clamp 8 and third pipe clamp 7 are closed, the second pipe clamp 10 is opened；In blood back
When, the second pipe clamp 10 is closed, after opening the first pipe clamp 8 and third pipe clamp 7, blood back can directly be carried out by fluid infusion, do not needed
Carry out termination of pumping work.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
