MOTOR DRIVEN FLUID ADMINISTRATION APPARATUS Filed Dec. 3, 1965 5e u g INVENTOR Wm'ven R. JQWQ l 3?) BY ATTORNEY5 Patented July 22, 1969 3,456,649 MOTOR DRIVEN FLUID ADMINISTRATION APPARATUS Warren R. Jewett, 44 Russell Ave., Orange, Conn. 06477 Filed Dec. 3, 1965, Ser. No. 511,503 Int. Cl. A61m /22 U.S. Cl. 128-214 3 Claims ABSTRACT OF THE DISCLOSURE A portable apparatus for use in the administration of liquids at a controlled rate comprising a syringe with movable plunger, a motor, and drive means all mounted on a patient supported base member. The drive means includes a threaded shaft which is arranged to move said plunger to force liquid from said syringe, The motor is arranged to drive said threaded shaft by means of a pair of gears and is pivotally mounted to enable disengagements of said gears.
This invention relates to an apparatus for administering fluids and more particularly to a small and lightweight portable system for the administration of physiological solutions at a controlled rate.
During the course of treating a patient in a hospital, it is often required that the patient who is being supplied with fluids intravenously be moved to another location in the hospital, for example, when it is required that X-rays be taken. The general hospital procedure is to have the bottle providing the intravenous fluid carried on a separate stand and be transported or rolled along the floor with the vehicle transporting the patient. This is done to maintain the intravenous site open as long as possible so that a doctor is not required to start a new site.
It has been found that this modus of operation is quite cumbersome for the nurse transporting the patient, inasmuch as both the patient and the stand carrying the intravenous fluid must be moved simultaneously. Additionally, in transporting the patient, a sudden turn or stop will often cause the needle in the patients vein to pull out, thus requiring that a new intravenous administration site be started.
In order to eliminate the above difficulties, applicant has provided a new, small and lightweight portable system which may be mounted on the patient, such as on a limb of the patient, and which is capable of continuously providing intravenous physiological fluids to the patient at a controlled rate.
This invention also provides apparatus which is adaptable for use on test animals, wherein fluids must be administered over long periods of time. Furthermore, the apparatus of this invention has application for dispensing fluids at a controlled rate, such as required in chemical analysis.
Accordingly, it is an object of this invention to provide a new and improved fluid administrtion apparatus.
Another object of this invention is to provide a new and improved small, lightweight portable apparatus for the administration of physiological solutions to a patient at a controlled rate.
A further object of this invention is to provide a new and improved fluid administration apparatus which may be secured to a patient while the patient is in transit so as to maintain an intravenous site open.
An additional object of this invention is to provide a new and improved fluid administration apparatus which does not interfere with the locomotion of a patient or a test animal.
Still other objects and advantages of the invention will in part be obvious and will in part appear hereinafter.
The invention accordingly comprises the apparatus possessing the features, properties, and relations of elements which will be exemplified in the apparatus hereinafter described and the scope of the invention will be indicated in the claims.
For a fuller understanding of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which FIG. 1 is a top view of the fluid administration apparatus according to the invention;
FIG. 2 is a side elevational view of the apparatus ac cording to the invention;
FIG. 3 is a sectional view taken along line 3-3- of FIG. 2; and
FIG. 4 is a schematic diagram illustrating an electric circuit for use in the apparatus shown in FIGS. 1-3.
Referring to FIGS. 1-3, there is disclosed at 10 the fluid administration apparatus according to the invention. The apparatus 10 includes a base plate 11 having a strap 12 coupled thereto for securing the apparatus to a limb of a patient. The base plate 11 may be formed with a contour similar to that of a limb of the patient and a foam rubber pad may be placed on the underside of the base plate so that the apparatus may be easily secured to the patient. If desired, means such as hinges may be coupled to the base plate 11 so as to permit the apparatus to be fastened to a stand or animal cage.
A syringe 13 is mounted on the base plate and has a tube 14 extending therefrom which is attached to a needle 15. The needle 15 may then be inserted into a patient in the normal manner. The syringe 13 is provided with a plunger 17 which is movable toward and away from the opening closest the tube 14. Mounted on top of the plunger 17 is a platten 18 which is secured to the top of a threaded shaft 19. The shaft 19 is provided with a flat 19a so that it may slide in supports 20a and 2012 along a corresponding flat provided in these supports. Positioned between Supports 20a and 20b is a drive gear 21 having a threaded hub 22 for engaging the shaft 19. The gear 21 meshes with a gear 23 mounted on a shaft 24 of an electric motor 25. The electric motor 25 is positioned on a support 26 which is piv-otally mounted at 27 to the base plate 11. At one end of support 26 there is provided a spring 28 which normally maintains the gears 21 and 23 in a meshing position. Also coupled to support 26 is a member 29 which, when depressed, may pivot motor 25 such that the gear 23 disengages the gear 21. Thus, after the plunger has been driven to the left (FIG. 1) by rotation of the gear 23 and gear 21, member 29 may be depressed to disengage gear 23 from gear 21 so that gear 21 may be rotated manually to return the plunger to its initial raised starting position. A battery 32 is also mounted on base plate 11 for providing energy to drive the motor 25.
Referring now to FIG. 4, there is disclosed an electrical circuit for operating and controlling the rate of fluid discharge from syringe 13. This circuit has the motor 25 and the battery 32 coupled in series with a potentiometer 33, an on-off switch 35 and a rnicroswitch 36. The microswitch 36 is positioned as shown in FIG. 1 for engaging the platten 18 so that the motor 25 may be deenergized. The switch 36 is normally in a closed position until it is opened by the platten 18. To adjlist the rate of fluid discharge, the resistance of the potentiometer 33 is adjusted to control the current flow provided to the motor.
It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efliciently attained and, since certain changes may be made in the above construction without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
I claim:
1. Fluid administration apparatus comprising a support member adapted to be afiixed to a patient, a syringe mounted to said base, said syringe having a movable plunger, a motor, drive means, said drive means including a shaft threadably received in support means therefor so that rotation of said shaft produces linear movement of said shaft, said shaft being arranged to move said plunger to force liquid from said syringe, a first gear threadably engaging said shaft, and a second gear mounted on the shaft of the motor for driving said first gear, said motor being pivotally mounted to said support member so that said motor may be pivoted to disengage said gears.
2. The apparatus of claim 1 wherein said support means comprises spaced apart members and said first gear is mounted to said shaft between said support members.
3. The apparatus of claim 1 further including biasing means urging said first and second gears into engagement.
