Abstract

The utility model discloses a support type accelerating unit for infusion, which comprises a bracket 10, and a bottle hanging bracket 11. The essential technical proposal is that an air cylinder 2 which can accelerate infusion is arranged on the bracket; the bottle hanging bracket is connected with the case of the air cylinder by a fixing rod 16; the top of a piston rod arranged on the air cylinder is connected with a tensioner; the lower part of the air cylinder is provided with an air vent 9. The infusion pressure can be controlled at about 0.4 kg/cm+[2] by the utility model which can be used for clinically rapid infusion under various conditions, such as salvaging the wounded in hospitals and field construction.

Description

Support type accelerating unit for infusion

This utility model relates to a kind of stent-type transfusion accelerator, belongs to medical instruments field.

Use transfusion rescue various critical patients clinical be common, but need accelerate transfusion speed according to the state of an illness sometimes, when running into mobile relatively poor infusion solutions, also need accelerate transfusion speed artificially, ran into this type of situation in the past, can only lean on the nurse to press and quicken, so not only increase nurse's labor intensity, and transfusion speed be very unstable with hand push.

The purpose of this utility model is at the problems referred to above, and a kind of stent-type transfusion accelerator that weighing apparatus is pressed that is similar to is provided.

Description of drawings;

Fig. 1: this utility model master pseudosection.

Fig. 2: this utility model vertical view.

Fig. 3: transfusion schematic flow sheet.

The utility model is to realize like this (referring to accompanying drawing 1-3):

This utility model comprises support 10, hangs bottle stand 11, and its technical essential is that the cylinder 2 that can accelerate transfusion speed is housed on support 10.Hang bottle stand 11 and connect cylinder baffle through fixed bar 16, piston rod 5 tops on the cylinder connect chest expander, and gas port 9 is arranged at the bottom of cylinder.

Below the other technologies feature is launched explanation;

The said chest expander of this utility model is a combiner, and it comprises pulling force frame 4, extension spring pole 7, extension spring 8, and the two ends of extension spring are separately fixed on the support of pulling force frame and cylinder bottom.Extension spring pole is contained in the spring-pulling ring, and its top and pulling force frame flexibly connect, and the lower end is fixed on the support of cylinder bottom.Above-mentioned chest expander also can be used the replacements of pulling force frame 4, rubber band and rubber band pole.

5-12 location aperture 6 arranged on the piston rod 5, the pin 3 that control piston descends is housed on the top cover of cylinder 2, the loose pin of a control piston decline yardstick is arranged on the piston rod.

Gas port 9 connects infusion bottle 13 through air hose 14, and the gas port place can install tolerance control valve 15 or place a clip on air hose 14, controls ventilation.Cylinder 2 adopts cylinder alignment pin 12 to be connected with support 10.

Operation principle of the present utility model is as follows;

Carry piston 1 according to amount of infusion and rise, and on the location aperture 6 on the piston rod 5, insert pin 3 and loose pin respectively.During transfusion, extract pin 3, the gas in the piston 1 compressing cylinder 2 is discharged through gas port 9 and is entered in the infusion bottle 13 tolerance control valve adjustable gas output.

This utility model embodiment

Cylinder 2 capacity are decided to be 1000 milliliters, length 0.2m, and the pitch-row of the location aperture 6 on the piston rod 5 is pressed 100 milliliters of gas flows of the every discharge of cylinder and is calculated boring, and piston rod 5 location aperture is topmost discharged the tolerance punching by 50 milliliters, and infusion pressure is controlled at 0.4kg/cm ²About.

Piston adopts rubber skin plug, and skin scribbles medical glycerol beyond the Great Wall.
