Abstract

A pulsating hydrojet lavage device comprising (a) curvilinear manifold means arranged about a longitudinal axis, including fluid inlet means and fluid outlet means, (b) a pump for pumping with pulsating pressure a washing fluid, and (c) supply means for conveying the washing fluid from the pump to the manifold means. The washing fluid may be a mixture of water, detergents and antiseptic liquids. One purpose of the device is to prepare quickly medical personnel for surgical operations.

Claims

1. A lavage device for hands and arms comprising:

a. curvilinear manifold means arranged about a longitudinal axis;

b. a portion of said curvilinear manifold means remote from said longitudinal axis including fluid inlet means;

c. a portion of said curvilinear manifold means adjacent said longitudinal axis including fluid outlet means;

d. said remote and adjacent portions of said curvilinear manifold means being mutually spaced and terminally interconnected;

e. a terminal end portion of said curvilinear manifold means being turned inwardly toward the longitudinal axis of said curvilinear manifold means;

f. a pulsating fluid supply connected to said fluid inlet means;

g. pump means in said fluid supply including means to provide a pulsating fluid supply at substantially 1,500 pulses per minute; and

h. drive means for said pump means.

2. a substantially cylinder-like inner wall having multiple inwardly directed outlet openings for discharging a washing fluid,

3. The lavage device of claim 2 in which the entrance to said washing chamber is closed with a flexible material so that an object to be washed is inserted in said washing chamber through said flexible material.

4. terminal portions of corresponding ends of each of said manifold units being turned inwardly toward the longitudinal axis of said washing chamber;

b. pump means for pumping with pulsating pressure a washing fluid at approximately 1,500 pulses per minute; and

c. supply means for conveying a washing fluid from said pump means to said manifold units.

5. The lavage device of claim 4 in which said washing chamber comprises at least three of the specified manifold units circumferentially arranged.

6. The lavage device of claim 4 in which said washing chamber is securely positioned within an enclosure means adapted so that an object to be washed may be inserted in said washing chamber, said enclosure means having drain means for removing discharged washing fluId.

7. The lavage device of claim 6 in which said enclosure means has an entrance which is closed with a flexible material so that an object to be washed is inserted in said washing chamber through said entrance.

8. A lavage device for hands and arms comprising:

a. at least two substantially cylinder-like washing chambers, each of said washing chambers comprising;

9. The lavage device of claim 8 in which the entrance to each of said washing chambers is closed with a flexible material so that objects to be washed are inserted in said washing chambers through said flexible material.

10. A lavage device for hands and arms comprising:

a. at least two cylinder-like washing chambers, each of said washing chambers comprising at least two manifold units circumferentially arranged with respect to the longitudinal axis of said washing chambers, each of said manifold units comprising;

11. The lavage device of claim 10 in which each of said washing chambers comprises at least three of the specified manifold units circumferentially arranged.

12. The lavage device of claim 10 in which said washing chambers are securely positioned within an enclosure means adapted so that objects to be washed may be inserted in each of said washing chambers, said enclosure means having drain means for removing discharged washing fluid.

13. The lavage device of claim 12 in which said enclosure means has an entrance before each of said washing chambers, each of said entrances being partially closed with a flexible material so that objects to be washed may be inserted in each of said washing chambers through said entrances.

14. A lavage device for hands and arms comprising:

a. a washing chamber defined by a plurality of L-shaped tubular elements circumferentially arranged in mutually spaced relation with respect to the longitudinal axis of said washing chamber, one leg of each of said L-shaped tubular elements secured at a terminal end thereof to a circular member, the terminal ends of the other legs of said L-shaped tubular elements being joined together at a central inlet means located on the longitudinal axis of said washing chamber, each of said tubular elements having a plurality of inwardly directed openings for discharging a washing fluid;

b. an enclosure means within which said washing chamber is securely positioned, said enclosure means adapted so that objects to be washed may be inserted in said washing chamber, said enclosure means havIng drain means for removing discharged washing fluid;

c. pump means for pumping with pulsating pressure a washing fluid at approximately 1,500 pulses per minute; and

d. supply means for conveying a washing fluid from said pump means to said washing chamber.
