Description
Technical field
This utility model relates to a kind of transfusion device, and especially a kind of barometric gradient pressurizing infusion set, belongs to the technical field of medical apparatus and instruments.
Background technology
Often need pressurize in anesthesia surgery and critical first aid quick infusion.The pressurizing infusion set using at present and sell, internal layer pressurised airbag is upper and lower symmetric design, and after giving inflating pressure, core projection, marginal portion volume is less than normal.This design easily makes medicinal liquid or blood products gather residual in bag upper end and periphery at pressure transfusion latter stage, cause administration, transfusion dosage inaccuracy or medicine, blood products waste.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of barometric gradient pressurizing infusion set, its compact conformation, can accelerate transfusion speed, and can reduce the residual, safe and reliable of liquid to greatest extent.
According to the technical scheme that this utility model provides, described barometric gradient pressurizing infusion set, comprise outer bag and be positioned at the pressurised airbag of described outer bag, the bottom of pressurised airbag arranges the airbag aeration mechanism being used for inflating to described pressurised airbag, and the top of pressurised airbag is provided with the transfusion bag hook for hanging transfusion bag; After pressurised airbag utilizes airbag aeration mechanism to inflate, the volume of pressurised airbag in outer bag diminishes from top to bottom gradually.
Described airbag aeration mechanism comprises the monitoring tube and inflating catheter that are connected with described pressurised airbag, and one end of described monitoring tube is connected with pressurised airbag through after outer bag, and the other end of monitoring tube arranges Pressure gauge; One end of inflating catheter is connected with pressurised airbag through after outer bag, and the other end of inflating catheter arranges inflating balloon, and the tail end of described inflating balloon is provided with inflation check valve.
Described inflating catheter is provided with three-way valve, and described three-way valve is between inflating balloon and pressurised airbag.
Described outer bag adopts transparent silicon poly-bag.
Top outside described outer bag is provided with outer bag fixation hook.
Advantage of the present utility model: pressurised airbag is in outer bag, after inflation, the volume of pressurised airbag from top to bottom diminishes gradually, thus can exert pressure by the liquid from top to bottom gradually in transfusion bag, ensure that liquid quick flowing from top to bottom in transfusion bag, avoiding liquid in transfusion bag assembles residual in upper end and periphery, and compact conformation is safe and reliable.

Description of reference numerals: 1-transfusion bag hook, 2-pressurised airbag, 3-outer bag, 4-Pressure gauge, 5-three-way valve, 6-monitoring tube, 7-inflating balloon, 8-inflate check valve, 9-inflating catheter and 10-outer bag fixation hook.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2: in order to can transfusion speed be accelerated, and the residual of liquid can be reduced to greatest extent, this utility model comprises outer bag 3 and is positioned at the pressurised airbag 2 of described outer bag 3, the bottom of pressurised airbag 2 arranges the airbag aeration mechanism being used for inflating to described pressurised airbag 2, and the top of pressurised airbag 2 is provided with the transfusion bag hook 1 for hanging transfusion bag; After pressurised airbag 2 utilizes airbag aeration mechanism to inflate, the volume of pressurised airbag 2 in outer bag 3 diminishes from top to bottom gradually.
Particularly, described outer bag 3 adopts transparent silicon poly-bag, it is softer that pressurised airbag 2 compares outer bag 3, the outer wall laminating of pressurised airbag 2 side is fixed on the inwall of outer bag 3, after pressurised airbag 2 is by the inflation of airbag aeration mechanism, between the outer wall of pressurised airbag 2 opposite side and the inwall of outer bag 3, there is the space holding transfusion bag, so that the extruding of pressurised airbag 2 pairs of transfusion bag can be realized, accelerate transfusion speed.Because the volume after pressurised airbag 2 inflation is for diminish gradually from top to bottom, namely the volume that pressurised airbag 2 upper end is given prominence to is greater than the outstanding volume in pressurised airbag 2 lower end, by the difference of pressurised airbag 2 filled volume, can effective extruding to transfusion bag be realized, reduce the residual of liquid in transfusion bag to greatest extent.
Further, described airbag aeration mechanism comprises the monitoring tube 6 and inflating catheter 9 that are connected with described pressurised airbag 2, and one end of described monitoring tube 6 is connected with pressurised airbag 2 through after outer bag 3, and the other end of monitoring tube 6 arranges Pressure gauge 4; One end of inflating catheter 9 is connected with pressurised airbag 2 through after outer bag 3, and the other end of inflating catheter 9 arranges inflating balloon 7, and the tail end of described inflating balloon 7 is provided with inflation check valve 8.
Described inflating catheter 9 is provided with three-way valve 5, and described three-way valve 5 is between inflating balloon 7 and pressurised airbag 2.Top outside described outer bag 3 is provided with outer bag fixation hook 10, outer bag 3 can be suspended at corresponding position and height by outer bag fixation hook 10.
During use by transfusion bag by the lower ending opening of outer bag 3 dispose into, and transfusion bag outer bag 3 being hung on pressurised airbag 2 upper end links up with 1 place, and transfusion bag is between the pressurised airbag 2 of outer bag 3 and internal layer.During inflation, three-way valve 5 is rotated to state obstructed with the external world, repeatedly extrude inflating balloon 7, make ambient atmos pass through to inflate check valve 8, inflating catheter 6 one-way flow, enter in the pressurised airbag 2 of internal layer.After inflation, internal layer pressurised airbag 2 expands, and exerts pressure from top to bottom, shows the pressure condition in pressurised airbag 2 by Pressure gauge 4, avoid the pressure in pressurised airbag 2 excessive, thus reach the object that flow rate of liquid is accelerated to the liquid in transfusion bag.The up big and down small structure of internal layer pressurised airbag 2 ensure that the liquid in transfusion bag flows from top to bottom fast, avoids the liquid that the upper and lower symmetric design of conventional pressurized transfusion bag air bag causes and gathers residual shortcoming in the upper end of transfusion bag and periphery.
