Abstract

The utility model relates to a non-gravitation infusion apparatus comprising a box body, a screw, two guide rods, a box cover, a liquid pushing plate, a stepping motor, a worm gear and worm reducing device, a driving pulley, a synchronous belt, a driven pulley and a bag bottom compression device, wherein one end of the box body is provided with a convex-shaped hole; the liquid pushing plate is provided with two unthreaded holes and a threaded hole; the two unthreaded holes are respectively connected with the two guide rods; the threaded hole is connected with the screw; the bag bottom compression device is used for compressing and fixing the bottom of an infusion bag; the stepping motor and the worm gear and worm reducing device transmit power to the screw through the driving pulley, the synchronous belt and the driven pulley to drive the liquid pushing plate to move, squeeze the infusion bag, and then realize non-gravitation infusion. Infusion speed is controlled by the rotating speed of the stepping motor. The apparatus can realize infusion by a non-suspended liquid bag and is flexible and convenient in use, controllable in infusion speed and capable of avoiding filling pollution. The non-gravitation infusion apparatus is especially suitable for infusion in the process of transporting the wounded by car, boat or plane in wars or disasters, not limited by infusion height and space.

Description

A kind of non-gravity transfusion device

Technical field:

This utility model relates to a kind of medical instruments field, relates in particular to a kind of non-gravity transfusion device.

Background technology:

At present, known transfusion is a kind of therapy commonly used clinically, and its fluid bag generally need hang on the drip stand, and medicinal liquid relies on gravity to splash in the patient body during transfusion, thereby transfusion bag must keep certain height just can keep normal transfusion.The method of this dependence gravity transfusion not only can make patient activity be restricted; And also bring a lot of inconveniences under many circumstances; For example, help to hold high transfusion bag when patient need at one's leisure need go out the nursing staff, otherwise occur blood back or bulge phenomenon easily; Very inconvenient, inconvenience more just when first aid in the open air and the disaster relief particularly.In addition; Common ambulance receives the restriction of gravity infusion model, can only establish the monolayer sick bed in the ambulance, this big limitations the appearance of ambulance suffer from performance; Particularly war, calamity etc. are concentrated under the situation of rescue occasion or ambulance anxiety at needs, have influenced the efficient of rescue and rescue greatly.

The utility model content:

This utility model technical problem to be solved is the deficiency that overcomes above-mentioned prior art, provides a kind of structure comparatively simple, easy to use, can be with regard to transfusable non-gravity transfusion device under the situation that need not hang.

For realizing above-mentioned purpose; The technical scheme that this utility model adopts is following: a kind of non-gravity transfusion device; By box body, screw rod, two guide posts, lid, push liquid sheet, motor, worm type of reduction gearing, driving pulley, synchronously band, driven pulley and bag base pressure tightly device form, it is characterized in that: described box body one end is provided with the convex shape hole, and motor and worm type of reduction gearing are installed in the top of box body; Driving pulley and worm type of reduction gearing link through flat key; Described two guide posts and screw axis are parallel to each other, and described push liquid sheet is provided with two unthreaded holes and a screwed hole, and two unthreaded holes link with two guide posts respectively; Screwed hole and screw rod link, and the lower surface of push liquid sheet is curved.

The tight device of described bag base pressure is used to compress and the fixing bag end of transfusion bag, and the bag base pressure tightly installs to be made up of depression bar, support ear seat, pressure spring plate, positioning and guiding bar, dog screw, spring and top pressing board.Wherein, The support ear seat is connected through the method and the box body of welding, and described depression bar takes the shape of the letter U, and its two middle side part is provided with the long waist shaped hole; And link through bearing pin with the support ear seat; The depression bar both-side ends links through bearing pin and pressure spring plate, and pressure spring plate is fixed on the positioning and guiding bar through dog screw, and top pressing board is fixed on the box body through screw.

During use, start motor, the power of motor and worm type of reduction gearing is through driving pulley, band and driven pulley pass to screw rod synchronously, and the screw drive push liquid sheet moves, the extruding transfusion bag, and then realize that non-gravity infuses.The speed of transfusion is by the rotating speed control of motor.

This utility model can be realized non-suspention liquid bag transfusion, and flexible and convenient to use, transfusion speed is controlled, and can avoid adding chemicals contamination.Be particularly suitable for fighting, calamity and car, ship and aircraft transport the transfusion in wounded's process, do not receive transfusion height and spatial constraints.

The beneficial effect of this utility model is: structure is comparatively simple, and is easy to operate, and the transfusion speed may command just need not hang and can infuse.
