Abstract
The utility model discloses an intravenous transfusion air guide needle which comprises a needle body, wherein the length of the needle body is matched with the height of a transfusion bottle; the air intake end of the needle body is connected with an air filter by a medical rubber pipe. The utility model effectively prevents bacteria which are contained in the air entering the transfusion bottle from polluting physic liquor, ensures transfusion safety and prevents transfusion infection.
Description
Technical field
This utility model belongs to the improvement of transfusion needle, particularly venous transfusion inducing QI pin.
Background technology
As everyone knows, the venous transfusion therapy has important role in the treatment of hospital, is indispensable method in the medical nursing work.And the safety of venous transfusion is more concerning millions upon millions of patients' health, the quality of medical care and the reputation of hospital.According to monitoring, dust particle greater than 0.5 μ m in relatively cleaner, as to be resting state indoor 50ml air reaches 5522, generally the dust particle greater than 0.5 μ m all reaches 8049 in dynamic air, and airborne antibacterial is normally attached on the dust granules, like this in the semi-hermetic type transfusion, infusion bottle is built-in changes dressings during liquid entering by transfusion needle when the air that contains antibacterial, will pollute the medicinal liquid in the infusion bottle, and the as easy as rolling off a log patient infusion that causes infects.
The utility model content
The purpose of this utility model is to provide a kind of venous transfusion inducing QI pin, can prevent from effectively to enter germ contamination medicinal liquid contained in the air of the built-in liquid of changing dressings of infusion bottle, guarantees the safety of infusing, and stops transfusion and infects.
The purpose of this utility model is achieved in that a kind of venous transfusion inducing QI pin, and the length of needle body is complementary with the height of infusion bottle at least, and the inlet end of needle body is connecting air filter by medical sebific duct.
During use, mouth of infusion bottle delead lid, sterilization, inversion are hung on the drip stand, this utility model inducing QI pin is taken out in sterile package, thrust a bottle Pi Sainei, pin was sent into until the bottle end of needle point near infusion bottle.Get universal disposable intravenous infusion set, folder closes air inlet pipe, and tip is thrust in the Infusion bottle lid, and medicinal liquid promptly enters in the tube for transfusion, presses venous transfusion procedure operation transfusion.Because liquid level in the high bottle outlet of needle point of this utility model inducing QI pin, the air that enters through air filter directly enters a bottle base space by needle tubing like this, in the displacement medicinal liquid input patient body, avoided contacting of air and medicinal liquid layer fully, can prevent the pollution of the air that enters medicinal liquid.Enter the air in the infusion bottle space, only contact with the medicinal liquid surface layer, because the surface tension of liquid effect, the microparticle of bringing into only can float on liquid surface, is difficult to pollute to the deep liquid diffusion.And surperficial liquid is the liquid that enters at last in the tube for transfusion, becomes raffinate to go out of use, and can not import in patient's body.So just solved the contaminated unsafe problems of transfusion liquid, approached the effect of total closed type transfusion, guaranteed the safety of infusing, stopped transfusion and infect.This utility model structure is very simple, and is easy to manufacture, safe and convenient to use, can increase how many use costs hardly, is easy to promote.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a main TV structure sketch map of the present utility model;
Fig. 2 is the structural representation of the another kind of embodiment of this utility model;
Fig. 3 is the A-A cross-sectional view among Fig. 2.
The specific embodiment
A kind of venous transfusion inducing QI pin as shown in Figure 1, comprises needle body 1, and the length of needle body 1 is complementary with the height of infusion bottle at least, and the inlet end of needle body 1 is connecting air filter 4 by medical sebific duct 3, and air filter 4 is the medical air filter.For the ease of needle body 1 is thrust in the infusion bottle, fixedly installing gripping sheet 2 in needle body 1 bottom near medical sebific duct 3, gripping sheet 2 is plastic sheet or sheet metal.Just can easily needle body 1 be thrust in the infusion bottle by pinching gripping sheet 2 like this, prevent the phenomenon of damaging needle body 1 because of undue force.This utility model can be used with existing universal disposable intravenous infusion set, only keep its transfusion function as long as the air inlet pipe clamp of disposable intravenous infusion set closed during use, and the inducing QI function is finished by this utility model inducing QI pin, pollutes thereby stop transfusion.
As further improvement of the utility model, embodiment as shown in Figure 2, mediastinum 9 is being set in the bottom of needle body 1, mediastinum 9 is divided into inlet channel 7 and liquid outlet channel 6 with the lower passage of needle body 1, the lower end of liquid outlet channel 6 is tube for transfusion 5 links, the upper opening 8 of liquid outlet channel 6 is positioned on the tube wall of needle body 1, distance between this opening 8 and needle body 1 needle point is less than the height of infusion bottle, the lower ending opening of inlet channel 7 links together with air filter 4 by medical sebific duct 3, and the upper end of inlet channel 7 is communicated with the needle body tube chamber.
As shown in Figure 3, the cross section of needle body 1 is circular, and inlet channel 7 wherein is semicircle with the cross section of liquid outlet channel 6.Better liquid sealing performance is arranged between cylindrical needle body 1 and the infusion bottle bottle stopper.By the architecture advances of this embodiment, make this utility model can replace existing universal disposable intravenous infusion set and use separately.
