Abstract
The utility model discloses a bagged liquor pump infusion device, comprising a plastic medical solution bag 1, an infusion tube 2, a perforating needle 3, a micro slow motor 12, a governing box 8 and a drain needle 4. An output shaft of the governing box 8 is fixed with an upper tube fluid driving wheel 6, on which an extrusion driving bowl 7 is symmetrically arranged. The extrusion driving bowl 7 rotates along an extrusion slot 5, through which the infusion tube 2 penetrates. The infusion device not only avoids the disadvantages of frangibility, cross infection and easy intrusion of atmospheric bacteria, but also has the advantages of without using of the hanger any more, convenient carrying, flexible use, no influence on the movement of patients and adjustable infusion speed, thus being able to be extensively beneficial to the infusion of various patients.
Description
This utility model relates to the improvement of transfusion device, and a kind of specifically packed liquid pump is gone into the formula transfusion device.
General transfusion device partly is made of glass medicinal liquid bottle, tube for transfusion, puncture needle etc. mostly at present, since this glass medicinal liquid bottle exist frangible, easily produce cross infection, atmospheric antibacterial easily enters shortcomings such as causing infusion reaction in the medicinal liquid, progressively replaced by plastic infusion bag.But the plastic bag transfusion device of usefulness is also the same with the transfusion of medicinal liquid bottle at present, needs medicinal fluid bag is hung on the support, utilize atmospheric pressure and medicinal liquid gravity to overcome the venous resistance, medicinal liquid is imported in the patient body, therefore, had the movable difficulty of patient too, transport shortcomings such as patient's inconvenience, amount of infusion be also wayward, in addition, it is also inconvenient, inaccurate to press the stalagmometer amount, can not be at regular time and quantity, for first aid patient pressurization, when quickening transfusion, more apparent inconvenience, wayward.
The purpose of this utility model be to provide a kind of need not support sling, can not produce cross infection, easy to use flexibly, can be at regular time and quantity, accurate measurement is adjustable, but both adjust blood pressure and regulate transfusion speed make things convenient for the active packed liquid pump of patient to go into the formula transfusion device again.
This utility model is achieved in that this packed liquid pump goes into the formula transfusion device, constitute by plastics medicinal fluid bag, tube for transfusion, puncture needle, miniature slow speed motor, governing box, fluid pin, its fluid pin inserts in the plastics medicinal fluid bag, tube for transfusion one end connects the fluid pin, the other end connects puncture needle, the fixing pipe liquid driving wheel of going up on the output shaft of its governing box, the symmetric extruding driving spin of establishing on the pipe liquid driving wheel, extruding drives spin and rolls along squeezing groove, tube for transfusion passes in the squeezing groove, drive spin extruding transfusion liquid in pipe by extruding, liquid in pipe is pressed in the patient body.This utility model is also implemented by following measure: squeezing groove arc length degree is consistent with the arc length that adjacent two extruding drive between the spin, the mouth that penetrates that the arc center of circle of squeezing groove and pipe liquid driving wheel concentric, tube for transfusion enter squeezing groove all is made as bell mouth shape with the extending port that stretches out squeezing groove; But extruding drives spin and is located at the end of adjust blood pressure spoke, but establishes pressure spring in the adjust blood pressure spoke, is fixed on the pipe liquid driving wheel but the adjust blood pressure spoke is symmetric, and the central shaft hole of pipe liquid driving wheel is fixed on the output shaft of governing box with pivot pin; Establish step-by-step variable gear in the governing box, establish speed governing on the governing box shell and turn round, establish the amount of infusion metering disk on the rotating disk that speed governing is turned round, turn round adjusting by the adjusting on the change speed gear box, according to metering disk indicated value control transfusion speed, press how many milliliter meterings of per minute, no longer calculate and drip number; The turning cylinder of miniature slow speed motor is connected transmission by gear with worm screw in the governing box, establish the plastics medicinal fluid bag in a side of pipe liquid driving wheel and place basket, tube for transfusion is placed the basket bottom by the fluid pin from the plastics medicinal fluid bag and is inserted in the plastics medicinal fluid bag, the plastics medicinal fluid bag is made of transparent plastic, so that observe the bag inner liquid medicine.
The utility model has the advantages that: compare with the vial medicinal liquid of present use, the shortcoming of having avoided frangible, cross infection, atmosphere antibacterial easily to enter, compare with the plastic bag transfusion device of present use, reuse suspension bracket not, easy to carry, use flexibly, does not influence patient and moves, in addition, transfusion speed is adjustable, is beneficial to various patient infusions.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 looks sketch map for this utility model structure master.
Fig. 2 drives spin drives the transfusion liquid in pipe in squeezing groove cross-sectional schematic for this utility model extruding.
Make this utility model with reference to accompanying drawing 1,2.This packed liquid pump is gone into the formula transfusion device, constitute by plastics medicinal fluid bag 1, tube for transfusion 2, puncture needle 3, miniature slow speed motor 12, governing box 8, fluid pin 4, plastics medicinal fluid bag 1 usefulness transparent plastic is made, be convenient to observe what of amount of liquid medicine, fluid pin 4 inserts in the plastics medicinal fluid bag 1, tube for transfusion 2 one ends connect fluid pin 4, the other end connects puncture needle 3, the fixing pipe liquid driving wheel 6 of going up on the output shaft of governing box 8, the symmetric extruding driving spin 7 of establishing on the pipe liquid driving wheel 6, extruding drives spin 7 and rolls along squeezing groove 5, and tube for transfusion 2 passes in the squeezing groove 5.Squeezing groove 5 arc length degree are consistent with the arc length that adjacent two extruding drive between the spin 7, the arc center of circle of squeezing groove 5 and pipe liquid driving wheel 6 concentrics, the mouth that penetrates that tube for transfusion 2 enters squeezing groove 5 is bell mouth shape with the extending port that stretches out squeezing groove 5, to reduce liquid flowing resistances in the tube for transfusion 2; But extruding drives spin 7 and is located at the end of adjust blood pressure spoke 9, but establishes pressure spring 14 in the adjust blood pressure spoke 9, but adjust blood pressure spoke 9 symmetric being fixed on the pipe liquid driving wheel 6, and the central shaft hole of pipe liquid driving wheel 6 is fixed on the output shaft of governing box 8 with pivot pin; Establish speed governing on governing box 8 shells and turn round 10, speed governing is turned round on 10 the rotating disk and is established amount of infusion metering disk 11; The turning cylinder of miniature slow speed motor 12 is connected transmission by the worm screw in gear and the governing box 8; Plastics medicinal fluid bag 1 is placed on the plastics medicinal fluid bag and places in the basket 13, and tube for transfusion 2 is placed basket 13 bottoms by fluid pin 4 from the plastics medicinal fluid bag and inserted in the plastic infusion bag 1.
