Abstract
The utility model relates to a double-layer pressurizing transfusion bag which overcomes the defects that the traditional transfusion bag can not automatically pressurize to realize the purposes of quick transfusion and blood transfusion when in need of pathogenetic conditions, the traditional transfusion bag always needs manual extrusion to complete, the operation is time consuming and laboursome, the dropping speed of liquid is not stable and the phenomenon of needle rolling is easy to occur. The double layer pressurizing transfusion bag adds a layer outside the original transfusion bag, thereby, the utility model achieves the purpose of quick transfusion by that air is injected into a gap between double layers by an injector or a miniature high-pressure inflator to maintain certain pressure.
Description
This utility model belongs to disposable medical transfusion articles for use, a kind of double-deck pressure transfusion bag that can realize transfusion fast or blood transfusion.
In clinical treatment, the normal due to illness needs of feelings must be infused or transfuse blood fast, but traditional transfusion bag can not realize by automatic pressurization, often need manual compression to finish, relatively waste time and energy and liquid infusion speed not steady.The purpose of this utility model is a kind of transfusion bag that can pressurize automatically of design, does not need manual compression just can realize the purpose of quick blood transfusion, transfusion, and drips speed steadily.
For achieving the above object, this utility model adopts following technical scheme:
Described double-deck pressure transfusion bag is to increase one deck again in the outside of former transfusion bag to form bilayer, establishes a check valve in outer field upper end and communicates with lacuna between the bilayer.
The utlity model has following superiority:
Because this utility model has adopted the outside of former transfusion bag to increase one deck more again, thereby make transfusion bag become double-deck two chambeies, what inner chamber was that original transfusion bag still adorns is liquid, exocoel is the lacuna between the bilayer, can be by the check valve on the skin to this gap gas injection and keep certain pressure, thus reach the purpose of quick blood transfusion, transfusion, avoided manual compression, time saving and energy saving and liquid droping speed is steady, and can avoid running pin.
Below in conjunction with the description of drawings specific embodiment of the utility model:
Figure one is the structural representation of double-deck pressure transfusion bag.
As shown in FIG.: 1. the suppending hole 2. of transfusion bag is that check valve (can by this valve to exocoel gas injection pressurization) 3. is that exocoel 4. is that inner chamber is the 5. skin of internal layer 7. transfusion bag of cutting tip 6. transfusion bag of transfusion bag of original transfusion bag (interior dress liquid)
Claims (1)
- Double-deck pressure transfusion bag is by internal layer (6), inner chamber (4), suppending hole (1), the cutting tip of transfusion bag (5) is formed, of the present utility model being characterised in that: described double-deck pressure transfusion bag, the outside that is again former transfusion bag increases the check valve (2) that one deck is outer (7) and outer upper end again, and pressurizes to exocoel (3) gas injection by check valve.
