Abstract
A medical sterilized oxygen filler for filling sterilized oxygen into transfusion bottles without altering gravity transfusion method or influencing transfusion speed during medical fluid (blood) transfusion. A soft plastic bag is used for connecting a plastic tube; the plastic bag is filled with a suitable volume of oxygen. When in use, the soft plastic tube is connected with an air inlet to a transfusion system, to fill purified sterilized oxygen during the transfusion in the condition of maintaining consistent pressure inside the transfusion bottle.
Description
When this utility model relates to a kind of medical transfusion (blood), in transfusion (blood) bottle, implement the device of aseptic filling oxygen.
Commercially available medical aseptic oxygenator is connected and forms with aerofluxus (close gas) valve closure by the rigid plastics pressure vessel at present, be filled with certain pressure oxygen in the plastics pressure vessel, the oxygenator air vent is connected with the disposable transfusion device air inlet pipe during use, regulate air bleeding valve then, charge into gradually in the infusion bottle after making the decompression of pressure vessel inner high voltage oxygen, reach the purpose of aseptic oxygenation.But because post-decompression oxygen and external atmosphere pressure still exist certain pressure poor, make the transfusion of gravity transfusion becoming pressure, and the big minor swing of this pressure differential, transfusion (blood) speed instability caused, not only increase burden, and work the mischief so that danger for patient's life and health to medical personnel.
The purpose of this utility model provides a kind of simple receptacle, aerofluxus (close gas) structure, and it can not only realize closed sterile soft oxygenation transfusion, and does not change the using method that disposable transfusion device can only the gravity transfusion.
The purpose of this utility model is achieved in that the flexible plastic pipe that connects a suitable aperture at medical aseptic soft plastic bag one end of a sealing with melt process, the plastic tube endoporus communicates with plastic bag inside, guarantee that pipe outer wall and the welding of medical plastic bag are closely airtight, behind the sterilization, get rid of gas in the bag, charge into the medical pure oxygen of suitable capacity, heat-sealable stopped pipe mouth.During use the oxygenation bag is hung upside down on drip stand, pinch plastic tube, oxygen in the closing bag with hands, cut and seal, be connected to the disposable transfusion device air inlet, get final product according to normal defeated infusion method operation then, along with liquid in the infusion bottle reduces gradually, oxygen is filled into infusion bottle gradually in the plastic bag.Finish the purpose of aseptic oxygenation transfusion.
Owing to adopt such scheme to avoid using existing medical aseptic oxygenator, infusion bottle pressure is raise, cause transfusion speed with infusion bottle internal pressure height speed instability.And do not change disposable transfusion device can only gravity the using method of transfusion.
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is example structure figure of the present utility model.
Fig. 2 is the I-I cutaway view of Fig. 1.
Fig. 3 is this utility model user mode.
Among the figure: 1, plastic bag; 2, plastic tube; 3, infusion bottle; 4, disposable transfusion device
In the embodiment shown in fig. 1, plastic bag (1) upper end is with the heat seal sealing, and extrudes a suitable big or small slotted eye, so that hang when using.Plastic bag (1) other end folds up a plastic tube (2), and plastic tube (2) outer wall is connected with the plastic bag hot melt, charges into behind the oxygen at distance plastic tube (2) port 3-5mm place heat sealing.
Claims (1)
- A kind of medical aseptic oxygenator, the container that holds oxygen connects an aerofluxus (close gas) valve, it is characterized in that the soft plastic bag that is filled with oxygen connects a flexible plastic pipe, seals.
