Description
Technical field
This utility model relates to medical instruments field, particularly a kind ofly is applicable to that intravenous vein prolongs pipe.
Background technology
In modern times in the curative activity, vein prolongs to be in control widely to be used, and the vein that uses at present prolongs pipe and is generally the threeway vein and prolongs pipe, prolong pipe used valve be three-way valve, three-way valve relies on three-way cock to come the flow direction of controlling liquid.But in clinical operation, the three-way valve that the threeway vein prolongs pipe except that an end with prolong manage be communicated with, all the other two ends connect transfusion device liquid and venous pump respectively; When in operation process; When needing interim dosing, the threeway vein prolongs pipe has not had the unnecessary port medicine of can annotating, can only unplug one of them port that connects transfusion device liquid or venous pump; Rely on the inside injectable drug of this transient port again; This brings very big trouble for the feeding operations in the clinical treatment, and the port after unpluging has increased and antibacterial and the chance that virus contacts, and brings potential safety hazard to the patient; And the length that existing vein prolongs pipe is generally 100mm, and often pipe is too short influence operation because of prolonging in use for doctor and nurse, and short vein prolongation is managed and is not easy to fix, often people restless and make the pipe slippage due to illness.
The utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, provides a kind of vein of feeding operations, moderate length that makes things convenient for to prolong pipe.
For realizing above-mentioned purpose, this utility model provides following technical scheme:
A kind of vein prolongs pipe, comprises prolonging pipe, and an end that prolongs pipe connects infusion connector, and said vein prolongs pipe and also comprises four-way pipe, and the other end of said prolongation pipe is communicated with one of them mouth of pipe of four-way pipe, is provided with three-way cock in the said four-way pipe.
Above-mentioned vein prolongs in the pipe, and said three-way cock can make any two mouths of pipe of four-way pipe manage conducting with prolongation simultaneously.
Above-mentioned vein prolongs in the pipe, and the length of said prolongation pipe is 150～500mm.
Above-mentioned vein prolongs in the pipe, and the length of said prolongation pipe is 150mm.
The vein of this utility model prolongs pipe through changing original tee T into four-way pipe; Still use three-way cock in the said four-way pipe; Increased the joint that is used as medicine thus; Can be in the operation intravenous injection directly through this joint dosing of being used as medicine, and need not unplug other mouth of pipe, influence the medicine that advances of other mouth of pipe; Vein after length increases prolongs just feeding operations of tube side, is convenient to fix, and due to illness people restless do not make the pipe landing.
Compared with prior art, the beneficial effect of this utility model:It is convenient that the vein of this utility model prolongs the pipe dosing, can reduce the contaminated chance of medicine; Moderate length is convenient to fix, and due to illness people restless do not make the pipe landing.
Description of drawings
Fig. 1 is that the vein of prior art prolongs the tubular construction sketch map.
Fig. 2 is the structural representation of this utility model.
Structural representation when Fig. 3 is embodiment 1 use.
Labelling among the figure: 1-prolongs pipe, and 2-infusion connector, 3-four-way pipe, 4-three-way cock, the 5-joint that is used as medicine, 6-prolong the pipe mouth of pipe.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is further described.
Embodiment 1
Shown in accompanying drawing 2; The vein of present embodiment prolongs pipe, comprises that length is the prolongation pipe 1 of 150mm, and an end that prolongs pipe 1 connects infusion connector 2; Said vein prolongs pipe and also comprises four-way pipe 3; The other end of said prolongation pipe 1 is connected with the prolongation pipe mouth of pipe 6 of four-way pipe 3, is provided with three-way cock 4 in the said four-way pipe 3, and said three-way cock 4 can make four-way pipe 3 any two mouths of pipe manage 1 conducting with prolongation simultaneously.
Present embodiment changes four-way pipe into through the tee T that original vein is prolonged pipe; Still use three-way cock 4 in the said four-way pipe 3; Four-way pipe 3 is except that prolonging the pipe mouth of pipe 6 and prolongation pipe 1 is communicated with, and all the other two mouths of pipe connect transfusion device liquid and venous pump respectively, and an also surplus mouth of pipe is as being used as medicine joint 5.Mouth of pipe A connects venous pump in the operation intravenous injection, and mouth of pipe B connects transfusion device liquid, and mouth of pipe A, mouth of pipe B and prolongation are managed the mouth of pipe 6 and communicated with each other through three-way cock 4, and medicinal liquid gets into four-way pipe through mouth of pipe A, mouth of pipe B, manages in the 1 inflow patient body through prolonging again; When the interim dosing of needs; Earlier three-way cock 4 is rotated counterclockwise 90 ° (shown in accompanying drawings 3), mouth of pipe A, the prolongation pipe mouth of pipe 6 and the joint 5 that is used as medicine communicate with each other, can be directly through joint 5 dosings of being used as medicine; And need not unplug other mouth of pipe; Influence the medicine that advances of other mouths of pipe, this moment, medicinal liquid got into four-way pipe 3 through mouth of pipe A, the joint 5 that is used as medicine, and flowed in the patient body through prolonging pipe 1 again; After treating that dosing is accomplished, again three-way cock 4 is turned clockwise 90 °, make four-way pipe 3 recover medicinal liquid conducting direction before.Vein after length increases prolongs pipe can reach 150mm, and moderate length is convenient to fix, and due to illness people restless do not make the pipe landing.
