Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
Shown in referring to figure 1, figure 2 and figure 3, the utility model embodiment provides a kind of Y type indwelling tube needle comprising plastic needle
Seat 1, attachment base 2, tube sealing clamp 10, puncture needle tube socket 7, sealing-plug 13 and ejector sleeve 14；Attachment base 2 and plastics needle stand 1 are using transparent
Material production, facilitates the transfusion condition of observation medical fluid after the completion of acupuncture treatment, while can find blood backflow in time, in time adjustment infusion
Posture avoids blood backflow overlong time, prevents danger；Tube sealing clamp 10 is formed using plastic production, passes through tube sealing clamp 10
The flow velocity of adjustable medical fluid, and can avoid tube sealing clamp 10 and scratch extension tube 9；The diameter of sealing-plug 13 is equal to plastics needle stand 1
Internal diameter, and sealing-plug 13 is tightly fixed to the inside of plastics needle stand 1, and sealing-plug 13 is made of halogenated butyl rubber, and
Halogenated butyl rubber has low-permeable, high damping property, resistance to ag(e)ing, weatherability, ozone resistance and chemical resistance, will not be with medicine
Liquid chemically reacts, and can avoid it and pollutes medical fluid, while can spring back hole repairing moment when puncturing needle tubing 7 and extracting out, prevents
Only medical fluid flows out.
Shown in Figure 1, the needle wing 5 is by copying human finger shape to make, and there are hemispherical bumps 6 on the surface of the needle wing 5,
Convex block is arranged along 5 chamfered shape of the needle wing, is met ergonomic designs, is facilitated medical staff preferably to grab when in use, together
When fixed-wing 16 be provided with two panels, and fixed-wing 16 is with the center line symmetry arrangement of plastics needle stand 1, in acupuncture treatment by fixed-wing 16
It is close to the skin of patient, plastics needle stand 1 can be prevented mobile, it is more stable to improve puncture success rate when making to puncture.
It is shown in Figure 3, the top that needle tubing 4 and ejector sleeve 14 are each fastened to puncture needle tube socket 7 is punctured, when pressing puncture needle tubing
When seat 7, ejector sleeve 14 pushes conduit 3 to be pierced into intravascular with puncturing needle tubing 4, and when unclamping puncture needle tube socket 7, spring 15 is by puncture needle
Tube socket 7 ejects, and ejector sleeve 14 and puncture needle tubing 7 are with the movement of puncture needle tube socket 7, and conduit 3 is left in place, and is implanted into conduit 3
Then blood vessel is extracted puncture needle tube socket 7 from plastics needle stand 1, and therefrom take out of needle tubing 4 is punctured.
When infusion, calparine cap 11 and nut cap 12 are removed from attachment base 2, attachment base 2 is connected with perfusion tube, then
Medical staff's index finger and the third finger clamp the needle wing 5, then lean against syringe needle 4 on the superficial skin of blood vessel, and by plastics needle stand 1
It is fixed on skin surface, plastics needle stand 1 is avoided to slide, the skin and blood vessel of the fixed site of puncture of another hand, the fixed pin wing 5
Hand thumb, which pushes to puncture branch holder 7 and push to puncture needle tubing 4 and ejector sleeve 14 and move spring 15, to be compressed, ejector sleeve 14 make conduit 3 with
Puncture needle tubing 4 be pierced into epidermis and enter blood vessel, then unclamp puncture needle tube socket 7, the rebound of spring 15 is by 7 bullet of puncture needle tube socket
Out, and puncture needle tubing 4 and ejector sleeve 14 is driven to be restored to original position, then puncture needle tube socket 7 is extracted out from the inside of plastics needle stand 1, and
It takes ejector sleeve 14, spring 15 out of and punctures needle tubing 4, sealing-plug 13 springs back to fill up through-hole and block rapidly, completes 3 implantable intravascular of conduit
It is interior, then tube sealing clamp 10 to be opened, medical fluid flows into attachment base 2 from perfusion tube, then flowed into plastics needle stand 1 by extension tube 9,
And flowed into blood vessel from conduit 3, achieve the purpose that infusion.
The utility model is not limited to above embodiment, for those skilled in the art, not
Under the premise of being detached from the utility model principle, several improvements and modifications can also be made, these improvements and modifications are also considered as this reality
Within novel protection scope.The content being not described in detail in this specification belongs to well known to professional and technical personnel in the field
