Abstract
The utility model provides an add outer cone joint of medicine, including outer cone joint body (1), add medicine spare (2), infusion passageway (3), add medicine passageway (4), rule awl (5), the inside cavity of outer cone joint body (1), hollow portion constitutes infusion passageway (3) and adds medicine passageway (4), infusion passageway (3) with add medicine passageway (4) intercommunication, add medicine spare (2) and seal up in the one end that adds medicine passageway (4), the outside that (5) were bored in rule sets up round double thread outer lane (6). Adding medicine spare and lieing in outer cone joint body, outer cone joint can dock with vein needle subassembly, and furthest dwindles with the distance between medicine position and the human body, reduces the potential safety hazard.
Description
Technical field
This utility model belongs to medical instruments field, particularly to a kind of dosing outer cone joint.
Background technology
During clinical infusion, interim dosing is the most common a kind for the treatment of means during the course.Particularly some drugs need to enter human body as early as possible, then the distance of dosing partial distance intravenous needle just determines medicine and enters the time of human body.
Current most of transfusion device dosing part with and the outer cone joint that docks of intravenous needle farther out, not reaching the medicine very first time enters the requirement of human body.And dosing passage may hide larger bubble because inner chamber is bigger, cause potential safety hazard.
In view of the deficiencies in the prior art, it is desirable to invent a kind of safer, closer to intravenous needle, the joint with medicine charging function.
Summary of the invention
This utility model provides a kind of dosing outer cone joint, can be joined directly together with intravenous needle, easy to operate, structure is more safe and reliable.
In order to reach object above, adopted the technical scheme that: a kind of dosing outer cone joint, including outer cone joint body, dosing part, infusion channel, dosing passage, Luer taper, the inner hollow of outer cone joint body, hollow space constitutes infusion channel and dosing passage, infusion channel and dosing channel connection, dosing part is sealed in one end of dosing passage, and the outside of Luer taper arranges a circle double thread outer ring.
As concrete technical scheme, described infusion channel, dosing passage connect in 45 degree of angles.Infusion channel, dosing passage connect discounting after the meaning in 45 degree of angles is to avoid flexible pipe bonding.
As concrete technical scheme, described dosing part can be welded on outer cone joint body, it is also possible to is that the mode using screw thread is screwed on outer cone joint body, dosing part and dosing passage interference fit.
As concrete technical scheme, dosing channel diameter about 2mm, the dead angle length≤3mm formed between dosing part and infusion channel.
Arranging dosing channel diameter 0～5mm, the meaning of the dead angle length≤10mm formed between dosing part and infusion channel is to reduce the probability of internal hiding bubbles, improves safety.
As concrete technical scheme, the inner surface of double thread outer ring is Double-layer threaded, in order to the fixing intravenous needle assemblies docked with Luer taper.
The beneficial effects of the utility model are: dosing part is positioned on outer cone joint body, and outer cone joint can dock with intravenous needle assemblies, reduce the distance between loading position and human body to greatest extent, reduce potential safety hazard.
Accompanying drawing explanation
Fig. 1 represents structural representation of the present utility model.
Wherein 1, outer cone joint body, 2, dosing part, 3, infusion channel, 4, dosing passage, 5, Luer taper, 6, double thread outer ring.
Detailed description of the invention
Provide this utility model preferred embodiment below in conjunction with the accompanying drawings, to describe the technical solution of the utility model in detail.
With reference to Fig. 1, a kind of dosing outer cone joint, including outer cone joint body 1, dosing part 2, infusion channel 3, dosing passage 4, Luer taper 5, double thread outer ring 6.
Outer cone joint body 1 uses macromolecular material integrated injection molding, inner hollow, and hollow space constitutes infusion channel 3 and dosing passage 4, and infusion channel 3 is connected with dosing passage 4.Dosing passage 4 diameter 0～5mm, the dead angle length≤10mm formed between dosing part 1 and infusion channel 3.Such design can allow bubble is more difficult when flowing through infusion channel 3 and dosing passage 4 to be rested in above-mentioned passage, and such exhaust process can be more efficient, reduces the probability that bubble is hidden.Infusion channel 3 and dosing passage 4 connect in 45 degree of angles, it is possible to give a discount after avoiding flexible pipe bonding.
Dosing part 2 can use natural rubber, uses thermofussion welding or bonding mode to be fixed on dosing passage 4, it is ensured that the sealing of dosing passage 4.When needing dosing, puncture dosing part 2 with the syringe of band pin, medicinal liquid is injected in dosing passage 4.
Dosing part 2 can also use the mode of nut, is screwed on dosing passage 4.When needing dosing, turn on nut, dock with dosing passage with the syringe without pin, medicinal liquid is injected in dosing passage 4.
Luer taper 5 is the female Luer of 6:100, can be connected with the joint of all identical taperings.Luer taper 5 is outside arranges a circle double thread outer ring 6, and double thread outer ring 6 inner surface is Double-layer threaded, can fix all devices docked with Luer taper 5.
Although the foregoing describing detailed description of the invention of the present utility model, but it should be understood by those skilled in the art that these are merely illustrative of, the scope of this utility model protection is as defined in appended claims.These embodiments, on the premise of without departing substantially from principle of the present utility model and essence, can be made numerous variations or amendment, but these changes and amendment each fall within protection domain of the present utility model by those skilled in the art.
