Fault Analysis Of A One-time Infusion - Infusion, Clinical - Medical Device Industry

Clinical application of a one-time infusion, not only effectively avoid cross-infection

, and the convenient and affordable. However, the actual use of some of the problems often encountered, such as improper handling can cause adverse effects, even life-threatening. Now experience below.

Infusion tube into the air above the

Infusion, if infusion bottle stoppers inserted after infusion tube with ventilation tube needle bevel needle relative distance closer, and the ventilation is slightly lower than the infusion needle position control needle position, the infusion tube of liquid flow generated by suction will be ventilated infusion needle bubbles inhalation tube. In addition, insert the needle after the infusion bottle cork stopper surface due to thin, stability is not strong, if the fluid infusion tube in the body by moving patients and other external influences, the infusion tube connected to the corresponding direction of the needle may occur, the location on the mobile. Subsequently, the infusion tube into the air or after the transfusion is also a result of moving the needle and the ventilation pipe into the gas needle is in the location of change. If the two needles in the air can enter the location of air from the infusion tube can place the needle into the infusion tube Department.

Treatment: (1) to prevent the air from the infusion tube at the top into the can or replacement fluid infusion tube to insert the needle into the cork, avoid the two needle bevel relative, and to maintain a certain distance; (2) transfusion, if found infusion tube at the top of the intake, should immediately rotate one of the two needles, turn around the direction of the needle bevel, so that the needle bevel direction of support or opposition, can now prevent air continues to enter.

Leakage of liquid from the air tube

To prevent liquid outflow, common practice is to infusion bottle stoppers on the ventilation tube needles Unplug or hand grip or pliers grip the ventilation tube moment, to be transported to a certain amount of fluid before the needle insertion or ventilation open ventilation tube. This not only wasted time and wastage. Treatment: (1) To prevent liquid leakage can be added into liquid infusion bottle, the attention drawn air is greater than or equal to the amount of added liquid; (2) In the case of liquid leakage can be fluid Unplug the tube after the needle, infusion bottle upside down so bottle of air from the ventilation needles Plaza. When the air pressure tends to balance inside and outside the bottle, the infusion tube then insert the needle, you can stop the leakage phenomenon [1].

Venous return Clinical transfusion medicine sometimes change does not add the liquid, the larger negative pressure due to infusion bottle, resulting in more blood circulation, in patients prone to psychological pressure. Treatment: You can replace the liquid every time, the attention to ventilation needle into first infusion bottle stopper, when the negative pressure into a positive pressure infusion bottle, then insert the infusion tube needles, it will avoid the return of blood transfusion tube phenomenon.

Liquid drops to stop and accompanied by blood reflux

Sometimes lost to the middle of infusion, the liquid input to stop the blood returning to the scalp continuously silicone tube. Hand pressure, it can squeeze the blood vessels, let go, the blood continued to return. Processing can then take a smooth needle into infusion bottle stopper, you can restore the normal fluid state [2].
