Abstract
The utility model discloses an infusion needle with a ventilating component, which comprises a needle seat, a small hose, a needle handle, a needle tube and a needle tube protecting sleeve. The infusion needle is characterized in that the ventilating component is mounted at the top end of the needle tube protecting sleeve. The ventilating component consists of a ventilating plug, and the ventilating plug is plugged in a ventilating hole of the protecting sleeve. Alternatively, the ventilating component consists of a ventilating plug and a water stopping air filter membrane, the ventilating plug is sleeved and fixed at the top end of the needle tube protecting sleeve, and a plug ventilating hole is separated from the ventilating hole of the protecting sleeve by the water stopping air filter membrane. Air can flow through the ventilating component while liquid cannot flow through the ventilating component, and simultaneously the ventilating component can prevent bacteria and dust from entering the infusion needle. The infusion needle with the ventilating component can prevent liquid medicine from flowing out via a needle hole to drop on the ground so as to be wasted and pollute environments, simultaneously, external bacteria and dust can be prevented from entering the infusion needle, and the infusion needle has the advantages of simple structure, simplicity in processing, safety, reliability and the like, is simple and convenient in operation without changing use habit of an operator and can be widely applied to clinical operation.
Description
Technical field
This utility model relates to the aseptic medical equipment that is used for the clinical transfusion purposes, especially relate to and a kind ofly be connected the supporting use in back, have with transfusion (blood) utensil ventilative, prevent the medicinal liquid water clock, prevent the transfusion needle of antibacterial and dust entering function.
Background technology
At present; The medical field transfusion needle is connected the supporting use in back with transfusion (blood) utensil usually; Common transfusion needle is formed by needle stand, little flexible pipe, needle handle, needle tubing and protective sleeve; Transfusion (blood) utensil is before transfusion, and medical personnel's interior whole emptyings of bubble of (blood) utensil pipeline of must manual work will infuse cause harm such as aeroembolism to prevent in the bubble entering patient body; Usually artificial deflated method is: after bottle plug puncture unit is inserted the infusion vessel bottle stopper, squeeze dropping funnel with hands, medicinal liquid is inhaled in the dropping funnel; After treating that medicinal liquid is full of about 2/3 volume of dropping funnel; Medicinal liquid flows in the long duct and to the transfusion needle direction and flows, and in the pin hole of transfusion needle, flows out at last, closes flow regulator then; Select to be fit to the position of puncture again, press usual manner puncture vein; In the process of this aerofluxus bubble; Often because offhand waste collection bucket, and drop on the ground after causing medicinal liquid to flow out in the pin hole of transfusion needle, not only polluted environment but also waste medicinal liquid; Therefore even waste several expensive medicinal liquids and cause doctor-patient dispute; Simultaneously in this process,, the antibacterial and the dust in the external world are got in the transfusion needle easily because of the end of the protective sleeve of common transfusion pin be an opening-wide state mostly.
Therefore; In the operation of clinical transfusion; Have air in the not only discharge line but also can prevent medicinal liquid water clock function, transfusion needle easy and simple to handle but provide a kind of, be used for preventing the pollution of the environment, the medicinal liquid of avoiding waste, prevent that antibacterial and dust from getting in the transfusion needle and just seem particularly important.
Summary of the invention
The purpose of this utility model is to provide a kind of can breathe freely, prevent medicinal liquid water clock, resistance bacterium, easy and simple to handle, safe and reliable transfusion needle in infusion process.
The purpose of this utility model is achieved in that
A kind of transfusion needle that has ventilative assembly, the needle tubing protective sleeve that is processed with the protective sleeve passage by needle stand, little flexible pipe, needle handle, needle tubing and top is formed, and characteristic is: on the top of needle tubing protective sleeve ventilative assembly is installed.
Said ventilative assembly is made up of porous plug, and porous plug is packed in the protective sleeve passage, can supply air to pass through but liquid can not pass through, and can prevent antibacterial and dust entering simultaneously.
Or; Said ventilative assembly is made up of the ventilative gag and the air filtration film that blocks water; Centre at ventilative gag is processed with the gag passage, and ventilative gag suit also is fixed on the top of needle tubing protective sleeve, and the air filtration film that blocks water that is placed in the ventilative gag separates gag passage and protective sleeve passage; Can supply air to pass through but liquid can not pass through, can prevent antibacterial and dust entering simultaneously.
This utility model is on the basis of traditional infusion pin, has set up ventilative assembly at the end of needle tubing protective sleeve.This utility model is the same with common transfusion needle operating procedure in use, need not change operator's use habit, and production and processing is simple.
This utility model in use; Usually be connected the supporting use in back with transfusion (blood) utensil, the bottle plug puncture unit of (blood) utensil of will infusing earlier inserts in the infusion vessel bottle stopper, squeezes dropping funnel with hands; Medicinal liquid is inhaled in the dropping funnel; After treating that medicinal liquid is full of about 2/3 volume of dropping funnel, it is interior and mobile to the direction of transfusion needle that medicinal liquid flows into the transfusion long duct, just stops to flow behind the end of medicinal liquid arrival needle tubing protective sleeve.Among this process, the gas in the pipeline is all discharged through ventilative assembly, thereby reaches the function of bubble in the emptying pipeline; Medicinal liquid flows out and is full of the inner chamber of needle tubing protective sleeve in the pin hole of transfusion needle; Medicinal liquid is water clock more not just; Prevent to drop on the ground after medicinal liquid from flowing out in the pin hole of transfusion needle, not only polluted environment but also waste medicinal liquid, simultaneously in this process; Because of ventilative assembly has fungi-proofing function, just can stop extraneous antibacterial and dust and get in the transfusion needle.
Therefore, the utlity model has following advantage: 1, in the bleeding process before transfusion, ventilative assembly has airing function, and the air in transfusion (blood) utensil pipeline can be discharged through ventilative assembly, has reached deflated purpose; 2, ventilative assembly has liquid-tight function, can prevent to drop on the ground and waste medicinal liquid and contaminated environment after medicinal liquid from flowing out in the pin hole of transfusion needle; 3, ventilative assembly has the function of fungi-proofing and dust protection, can prevent that extraneous antibacterial and dust from getting in the transfusion needle.4, simple, safe and reliable, the easy processing of product structure, easy and simple to handle need not change operator's use habit, can be widely used in clinical.
