Background technology
At present, when infusing, infusion bottle or transfusion bag need to be suspended on the position higher than patient mostly, to increase the pressure of medicinal liquid, ensure that medicinal liquid flows into patient's vein, and anti-return blood phenomenon.In one-horse outdoor or field, then not there is the condition hanging infusion bottle or transfusion bag, therefore need a kind of do not need to hang people can the infusion set of normal infusion.In recent years, by the effort of technical staff, having have developed can product accordingly.Such as, notification number is the utility model patent " negative-pressure infusion apparatus " of CN202105252U.Transfusion bag is set to U-shaped by this patent, water delivery bag indentation, there is provided with retractor device, described retractor device to be arranged on inside water delivery bag between two bags of walls or to be arranged between two bags, the outside wall of water delivery bag, and the place described water delivery bag being provided with retractor device is provided with reinforcement.When giving patient infusion, U-shaped transfusion bag being enclosed within the arm of patient tightly, making U-shaped transfusion bag clamp arm and producing the pressure being greater than human blood-pressure, making medicine flow into human body smoothly.Although this patent achieves and normally completes transfusion when not hanging transfusion bag, U-shaped transfusion bag is only enclosed within patient's arm, easily causes patient uncomfortable, affects blood circulation.
Summary of the invention
In order to meet under simple and crude conditioned disjunction specific condition as the natural disasters such as earthquake, floods, war occur time, when not possessing transfusion condition as made up a prescription, high-altitude suspension infusion treatment.If war or accident severely injured people when couching, realizing infusion treatment instantaneously, just can save the life of critical patient.The invention provides a kind of do not need soft transfusion bag to be suspended on eminence, can automatic or manual formed negative pressure, all can the negative pressure assist device of soft bag infusion of infusion treatment at any height.
The present invention realizes above-mentioned technical purpose by following technological means.
The negative pressure assist device of soft bag infusion, comprise loading plate, be fixed on the first aluminum corner brace on loading plate, the second aluminum corner brace, the 3rd aluminum corner brace, pressure roller, pressure regulator, be arranged on the spool in the first aluminum corner brace, the second aluminum corner brace, the power supply of mutual series connection, switch, potentiometer, motor, and the first gear and the second gear; Described motor and the first gear are arranged in the 3rd aluminum corner brace, described second gear and spool are arranged in the first aluminum corner brace, the second aluminum corner brace, described spool is provided with clamping device, described pressure roller is positioned at the below of spool, and the two ends of described pressure regulator are all fixed on loading plate, mid portion is crossed over and is pressed on pressure roller.
Further, described clamping device is spool groove.
Further, described power supply, switch, potentiometer are all arranged on loading plate.
Further, described power supply is battery.
Power supply described in the present invention, motor provide power for the negative pressure assist device of described soft bag infusion, described first gear, the second gear by power transmission to spool, described spool pulls the top of transfusion flexible bag, and the medicinal liquid that pressure roller is extruded in transfusion flexible bag is evenly imported in human body.Described switch, potentiometer are as the electric power regulating system of described negative pressure assist device.Particularly, described switch is for controlling the unlatching of described negative pressure auxiliary device work, and described potentiometer is for controlling flow velocity and the flow of infusion products.Described loading plate is for placing plan infusion products, and the first gear, the second gear, spool, pressure roller, pressure regulator, motor, the first aluminum corner brace, the second aluminum corner brace, the 3rd aluminum corner brace are fixed thereon simultaneously, have feature simple and compact for structure.
The beneficial effect of the negative pressure assist device of soft bag infusion provided by the invention is: can provide for transfusion flexible bag the power producing negative pressure, soft bag infusion is not needed clinically hang, easy to use, transfusion flexible bag is positioned at any height, place all can input body by medicinal liquid uniformly.Can be widely used in hospital, family, outdoor or field rescue treatment, especially adapt to long period outdoor or field rescue and use needs, particularly during war, natural disaster lies in the treatment of the sick and wounded on stretcher.
In addition, the cost of manufacture of the negative pressure assist device of soft bag infusion of the present invention is low, can reuse, and the feature of environmental protection is good.
