Description
Technical field
It is specifically a kind of embedded to be worn for the subcutaneous of haemodialysis artery and vein puncture the present invention relates to a kind of medical instrument
Thorn device.
Background technique
Haemodialysis, abbreviation hemodialysis, popular saying are also referred to as artificial kidney, wash kidney, are one kind of blood purification technology.
It utilizes semi-permeable membrane principle, is moved by harmful and extra metabolic wastes various in disperse, convection current body and excessive electrolyte
It is external out, achieve the purpose that purify blood, and achieve the purpose that correct Water-Electrolyte and acid-base balance.Hemodialysis is best
Vascular access is using internal arteriovenous fistula, and false aneurysm is formed and thrombosis is the main reason for internal fistula loses function.Internal fistula is lost
Main methods are implantation artificial blood vessel connection arteriovenous ends after function.Haemodialysis needs frequent progress vascular puncture, leads
It causes patient to fear puncture, influences the success rate punctured, be unfavorable for haemodialysis and carry out safely.
Summary of the invention
The purpose of the present invention is to provide a kind of subcutaneous embedded sting device for haemodialysis artery and vein puncture, with
Solve the problems mentioned above in the background art.
To achieve the above object, the invention provides the following technical scheme:
A kind of subcutaneous embedded sting device for haemodialysis artery and vein puncture, including puncture island, venipuncture portion
With arteriopuncture portion, the venipuncture portion and the setting of arteriopuncture portion are worn on puncturing island in venipuncture portion and artery
The top side detachable in thorn portion is equipped with one layer of puncture film, is communicated with vein end in the venipuncture portion, arteriopuncture connects in portion
It is connected with arterial end, blood vessel loop is communicated between venipuncture portion and arteriopuncture portion, connects venipuncture portion, arteriopuncture in portion
It is logical, so as to realize the flowing of blood in human body, guarantee to use safely after access punctures island.
It is further: it is described to puncture the island PC material high using biocompatibility, shape surface impulse- free robustness, ultra-thin knot
Structure gives patient's bring sense of discomfort when subcutaneously burying to reduce.
It is further: the venipuncture portion, arteriopuncture portion be blind hole, bury puncture island when make venipuncture portion,
Arteriopuncture portion is open outwardly.
It is further: the puncture film fabulous, puncture-resistant material using silica gel material or other biological compatibility,
Film service life is punctured once reaching, island can be also punctured by separation of simply performing the operation, replacement punctures film, effectively extends and puncture island
Service life.
Further: the vein end, arterial end, blood vessel loop use terylene, polytetrafluoroethylene (PTFE), polyurethane or natural silkworm
Silk.
Compared with prior art, the beneficial effects of the present invention are:
The device buries subcutaneous in patient forearm, by arterial end, vein end, punctures island and blood vessel loop and forms.For replacing
Need to be implanted into the patient of artificial blood vessel at present.Compared with prior art, have and puncture convenience, effectively prevent infection, service life
The advantages such as long, replaceable puncture film.
Patient can be made no longer to fear each vascular puncture, effectively improve puncture success rate.It is short since there are arteriovenous for inside
Road, blood flow is big, can effectively avoid thrombosis, prevents the generation of false aneurysm.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of subcutaneous embedded sting device for haemodialysis artery and vein puncture.
In figure: 1- punctures island, 2- venipuncture portion, 3- arteriopuncture portion, 4- vein end, 5- arterial end, 6- blood vessel loop.
Specific embodiment
Embodiment 1
Please refer to figure, in the embodiment of the present invention, a kind of subcutaneous embedded puncture dress for haemodialysis artery and vein puncture
It sets, including punctures island 1, venipuncture portion 2 and arteriopuncture portion 3, puncture the PC material high using biocompatibility of island 1, processing
Surface impulse- free robustness, superthin structure are shaped, gives patient's bring sense of discomfort when subcutaneously burying to reduce；The venipuncture portion 2
With the setting of arteriopuncture portion 3 on puncturing island 1, venipuncture portion 2, arteriopuncture portion 3 are blind hole, are made when burying and puncturing island 1
Outwardly, the top side detachable in venipuncture portion 2 and arteriopuncture portion 3 is equipped with for venipuncture portion 2, the opening of arteriopuncture portion 3
One layer of puncture film, punctures film fabulous biocompatibility, silica gel of puncture-resistant or other materials can be used and constitute, and wears once reaching
Film service life is pierced, can also puncture film by separation puncture island 1 of simply performing the operation, replacement, effectively extend puncture island 1 uses the longevity
Life, venipuncture portion 2, arteriopuncture portion 3 end on screw thread be stamped sealing cover, keep inner sealing, avoid infection.
Vein end 4 is communicated in the venipuncture portion 2, the other end of vein end 4 is connected to the vein blood vessel of human body,
Arterial end 5 is communicated in arteriopuncture portion 3, the other end of arterial end 5 is connected to the arteries of human body, venipuncture portion 2
It is communicated with blood vessel loop 6 between arteriopuncture portion 3, makes the interior connection in venipuncture portion 2, arteriopuncture portion 3, so as to realize people
The flowing of internal blood guarantees to use safely after access punctures island 1；The vein end 4, arterial end 5, blood vessel loop 6 are using existing
Mature artificial blood vessel technology and material production, material are polyurethane.
Embodiment 2
The vein end 4, arterial end 5, blood vessel loop 6 material can also be terylene, polytetrafluoroethylene (PTFE) or natural mulberry silk.
By arteriovenous end respectively with arteriovenous anastomosis, end, which is connected to, punctures island, and the blood vessel loop at rear portion forms short circuit.Every time
When dialysis, after sterilizing skin, from (arterial end) before puncture island, the piercing of (vein end) puncture portion can be completed puncture needle afterwards.Operation letter
Just, Low-grade nurse can also effectively avoid puncture failure with easy manipulation.Also no longer arm-rest belt is needed to fetter when puncture, into one
Step reduces the chance of thrombosis.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
