Description
Technical field
This utility model relates to medical tube for transfusion, is meant a kind of dual fail-safe safe transfusion tube especially.
Background technology
At present, the traditional tube for transfusion that in clinical treatment, uses (Jimo Fes pipe), need medical personnel constantly to observe liquid level in use, preventing that transfusion from finishing in the air admission tube for transfusion of back reaches backflow of blood, this tube for transfusion increases medical personnel's labor intensity, the present inventor is through research, invented can seal automatically after a kind of transfusion is finished, tube for transfusion safe in utilization.
The utility model content
The purpose of this utility model is to provide a kind of a kind of dual fail-safe safe transfusion tube easy to use, safe.
The purpose of this utility model is achieved in that a kind of dual fail-safe safe transfusion tube, comprise body, wherein: described body is made up of upper tube body and lower tube body, pass through the connector fixed seal connection between the upper and lower body, middle part at connector is provided with through hole, connector upper surface in the through hole periphery is provided with annular groove, one connecting rod is arranged in through hole, leave fluid passage between this connecting rod and the through hole, be provided with the umbrella hat that is positioned at upper tube body in the upper end of connecting rod, be provided with the buoyancy aid that is positioned at lower tube body in the lower end of connecting rod; The lower edge of described umbrella hat contacts sealing with the cell wall of annular groove.
The outer wall of the annular groove described in above-mentioned a kind of dual fail-safe safe transfusion tube is the inclined-plane.
The outer wall of the annular groove described in above-mentioned a kind of dual fail-safe safe transfusion tube is a vertical, and the lower edge of umbrella hat is upturned.
After this utility model adopts said structure, because of can forming with groove, the umbrella hat lower edge contacts sealing, after transfusion is finished, managing intravital liquid level position reduces, the umbrella hat lower edge is contacted with groove walls form sealing, simultaneously, the liquid level in the groove can also form the liquid level sealing, further strengthen sealing property, it is to the double insurance effect.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing, but do not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of this utility model;
Fig. 2 is the structural representation of the another kind of specific embodiment of this utility model;
Fig. 3 is a practical view of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of dual fail-safe safe transfusion tube of the present utility model, comprise body 1, body 1 is made up of upper tube body 11 and lower tube body 12, pass through connector 2 fixed seal connections between the upper and lower body 11,12, be provided with through hole 21 at the middle part of connector 2, connector 2 upper surfaces in through hole 21 peripheries are provided with annular groove 22, one connecting rod 3 is arranged in through hole 21, leave fluid passage 23 between this connecting rod 3 and the through hole 21, be provided with the umbrella hat 4 that is positioned at upper tube body 11 in the upper end of connecting rod 3, be provided with the buoyancy aid 5 that is positioned at lower tube body 12 in the lower end of connecting rod 3; The lower edge of described umbrella hat 4 contacts sealing with the cell wall of annular groove 22, and wherein the outer wall 221 of annular groove 22 is the inclined-plane, umbrella hat is formed with the outer wall 221 of groove 22 contact sealing.
The outer wall 221 of the annular groove 22 in this utility model also can be vertical, and the lower edge 41 of umbrella hat 4 is upturned, and can form the contact sealing equally, as shown in Figure 2.
When this utility model specifically uses, when normal infusion, liquid level in the lower tube body 12 is higher, buoyancy aid 5 up moves under buoyancy function, umbrella hat 4 is not contacted with groove 22 cell walls, transfusion liquid flows in the lower tube body 12 by the fluid passage 23 between through hole 21 and the connecting rod 3 through behind the upper tube body 11, realizes normal infusion; When no liquid in the upper tube body 11 flowed into, the liquid levels in I's body 12 constantly descended, and buoyancy aid 5 constantly descends with liquid level, driving umbrella hat 4 moves down, when the liquid level in the lower tube body 12 arrived certain position, the lower edge of umbrella hat 4 contacted with groove 22 walls, formed the contact sealing; Simultaneously, the liquid in the groove 22 forms the liquid level sealing, guarantees tube for transfusion and air insulated, prevents in the air admission lower tube body 12, also can prevent backflow of blood simultaneously.
