Abstract
The utility model relates to the needle of an infusion device, which is composed of an air inlet passageway and a liquid outlet passageway. The air inlet passageway of the needle head part inserted in an infusion bottle is longer than the liquid outlet passageway, so the air outlet of an air passageway can be positioned above the liquid surface of medicine liquor; so the air entering the air passageway is avoided contacting with the medicine liquor of a bottle, which solves the pollution to the medicine liquor by the unclean air and the polluted air; probable iatrical accidents caused by the pollution of the medicine liquor are avoided.
Description
This utility model relates to the syringe needle on the transfusion device that supplies transfusion usefulness in a kind of medical treatment, and particularly a kind of inlet channel and liquid outlet channel are formed, and are used for being inserted in the syringe needle for transfusion device on the infusion bottle.
Fluid therapy in the medical treatment has become general therapy commonly used.For the medicinal liquid in the infusion bottle is imported human body, adopted a kind of transfusion device, at the syringe needle that has to be used for being inserted on the infusion bottle on the transfusion device, this syringe needle has dual pathways formula structure, a passage outputs to human body for medicinal liquid, and another passage then enters infusion bottle for outside air, keeps the balance of bottle inner and outer air pressure, so that medicinal liquid normally exports, and the medicinal liquid import and the air outlet slit that are positioned at the needle tip of syringe needle are in sustained height., the needle point of syringe needle just can make medicinal liquid output in the medicinal liquid because can only submerging, thereby must could arrive ullage space the infusion bottle through medicinal liquid from the air that needle tip inlet channel inlet enters, this process provides capital chance to air with contacting of medicinal liquid.Problem is that statistics shows, contains about 300,000 of antibacterial in every cc of air, and particularly in populous, the accumulative place of patient, then air will be subjected to severe contamination.Obviously, unclean and contaminated air produces pollution with fully contacting then of medicinal liquid to medicinal liquid, thereby is communicate illness in the infusion process, even causes malpractice that approach is provided.
The purpose of this utility model is to provide a kind of syringe needle for transfusion device, the air and the medicinal liquid that enter in the infusion bottle is isolated, thereby make air have no chance to contact with medicinal liquid, solves the pollution problem of unclean air to medicinal liquid with this.
This utility model is realized by this way: at original syringe needle, only need the former air duct that is positioned at syringe needle one end is extended upward certain-length, the air duct outlet can be reached on the infusion bottle herb liquid liquid level, can reach the purpose of medicinal liquid and air insulated, guarantee the normal output of medicinal liquid simultaneously again.Air duct when the air admission syringe needle, then directly enter the space on the liquid level in the infusion bottle along passage, avoided and the contacting of medicinal liquid, because various antibacterials and virus are atomic little and extremely light, thereby its major part vacillates on liquid level, and small part contacts with liquid level and can only swim in liquid level, when medicinal liquid will be use up because the limitation in height of liquid outlet channel inlet, naturally residual certain medicinal liquid in the bottle is with getting final product that it is abandoned.
This utility model is simple and rationally, it is extremely convenient to make, has solved the pollution problem of air to medicinal liquid, thereby has avoided so and the malpractice that may form.
The embodiment that provides below in conjunction with accompanying drawing further specifies this utility model.
Fig. 1 is the present embodiment sketch map.
Fig. 2 is a present embodiment inlet channel cross-sectional view.
Fig. 3 is the cross-sectional view of present embodiment liquid outlet channel and inlet channel coupling part.
Fig. 4 is the cross-sectional view of present embodiment liquid outlet channel.
With reference to the accompanying drawings 1, syringe needle is made up of inlet channel 1 and liquid outlet channel 2, liquid outlet channel 2 has medicine liquid outlet 3 and infusion tube interface 4, during use, infusion tube is connected on the interface 4, the needle point of syringe needle inserts in the infusion bottle, and the channel outlet of syringe needle inlet channel 1 is positioned on bottle inner liquid medicine liquid level, and it is dustproof to add dustproof sponge plug at the air inlet of passage 1.
Claims (1)
1, a kind of syringe needle for transfusion device has needle point, is made up of inlet channel and liquid outlet channel, it is characterized in that: syringe needle is positioned at the length of inlet channel of needle point one end greater than the length of liquid outlet channel.
