Surgical suction floor mat

This disclosure relates to the field of surgical floor mats. More particularly, the disclosure relates to a simplified construction for a surgical floor mat configured to be comfortable to stand on for extended periods of time, to contain and route surgical fluids against spillage onto the floor, and to connect to a source of negative pressure for evacuation of fluids from the mat.

Improvement is desired in the construction of surgical suction floor mats. Because surgical floor mats are single use in nature, it is desired to reduce the cost of such floor mats by providing a design that is uncomplicated, yet provides the desired qualities of being comfortable to stand on for extended periods of time, being configured to contain and route surgical fluids against spillage onto the floor, and being configured to connect to a source of negative pressure for evacuation of fluids from the mat.

The present disclosure relates to a surgical suction floor mat of simplified construction.

The disclosure relates to a surgical suction floor mat for collecting and evacuating surgical fluids.

In one aspect, the mat includes a foam body having a surrounding border and a series of grooves defined on a first portion of the foam body. The grooves are located interior of the border and defined substantially across the foam body. The grooves uniformly increase in depth from adjacent a first side of the border of the foam body to a location adjacent an opposite second side of the border of the foam body, the grooves each being closed at a first end proximate the first side of the foam body and open an opposite second end;

A plurality of spaced apart upper surfaces are in-between the grooves and are of a substantially uniform elevation to permit a relatively uniform and level upper mat surface on which a user can stand. A collection channel is defined on a second portion of the foam body, the channel extending substantially perpendicular across the grooves, the collection channel being closed at each end and along one side of its length and the other side of the channel being open to and in flow communication with the grooves.

A suction fitting is in fluid communication with the channel and placeable in flow communication with a source of suction to evacuate fluids from the channel through the suction fitting.

The disclosure advantageously enables lightweight disposable surgical suction mats having simplified construction with a relatively uniform and level upper surface on which the user can stand.

With reference to the drawings, there is shown a surgical suction floor mat 10 according to the disclosure. The mat 10 includes a foam body 12 and a suction fitting 14 . If desired, an absorbent surgical drape 16 may be secured underneath and extend outward from the mat 10

The foam body 12 may be made of a foam material such as a closed cell polyurethane foam. The foam body 12 is preferably substantially fluid impermeable. The foam body 12 is preferably of one-piece molded construction. However, the body 12 may be made of multiple foam pieces adhered together. The foam body 12 is substantially rectangular and has a surrounding border 18 having apertures 18 a that may be used for carrying or for hanging the mat 12 for storage. A series of grooves 20 are located interior of the border 18 and defined across a dimension of the mat, such as in a direction from a front F of the body 12 to a rear R of the body 12 .

The grooves 20 uniformly increase in depth from the front F to the rear R of foam body 12 . That is, the grooves 20 are very shallow adjacent the front F and deepen toward the rear R so that each groove 20 provides a sloped drain surface 20 a that slopes from the front F of the mat 10 toward the rear R of the mat 10 . The grooves 20 are closed at their proximal end adjacent the border 18 at the front F of the body 12 and are open at their opposite terminal ends where they are the deepest, and terminate at a collection channel 22 that extends substantially perpendicular across the grooves 20 ( FIG. 4 ). The channel 22 has a depth corresponding to at least the maximum depth of the grooves 20 and is closed at each end and along one side of its length by the border 18 and the other side of the channel 22 is open to the grooves 20 .

The grooves preferably have a substantially uniform width of about 0.25 inches. The depth of the grooves 20 preferably uniformly taper from a depth of about 0.125 inches to about 0.75 inches over the length of the grooves, which length preferably is about 18 inches. Thus, the ratio of change in depth of the grooves to the length of the grooves is about 0.03.

The suction fitting 14 may be a suction T-fitting and may include a filter 24 . The filter 24 is preferably a foam filter made of a large pore side open cell polyurethane foam, known as a reticulated foam. The suction fitting 14 extends through an opening 26 through the border 18 at the rear side of the body 12 opposite the channel 22 and is in flow communication with the channel 22 . Surgical fluids travel via the grooves 20 to the channel 22 where they are evacuated by suction through the suction fitting 14 and a suction line 28 connected thereto.

The material in-between the grooves provides spaced apart upper surfaces 30 a that are of substantially uniform elevation to permit a relatively uniform and level, relative to the underying floor, upper surface 30 on which the user can stand. In this regard, the grooves 20 are preferably substantially parallel to one another. The portions of the border 18 immediately adjacent the grooves 20 have an elevation substantially corresponding to the elevation of the upper surfaces 30 a in-between the grooves to further provide a uniform and level surface on which the user can stand. In this regard, the relatively narrow width of the grooves 20 is easily spanned by the sole of the shoe of a user.

The use of a reticulated foam for the filter 24 advantageously diffuses the suction force or vacuum across the surface area of the filter 24 to create multiple small flow paths in a compact filter size for the travel of liquids. It has also been observed that the provision of multiple small dimensioned flow paths advantageously reduces the noises or sounds associated with the suctioning of the fluids from the mat and also advantageously provides effective filtration of relatively large particulates in the fluid that would tend to enter the suction fitting 14 and clog the suction fitting 14 and the suction lines 28 .

Turning to FIGS. 5 and 6 , there is shown an alternate embodiment of a surgical mat 50 according to the disclosure. The mat 50 is substantially similar to the mat 10 , except that it has two foam bodies 52 and 54 instead of the single foam body 12 , and it has a collection channel 56 that is covered.

The foam body 52 is substantially rectangular and has a series of grooves, such as the grooves 20 , defined thereon. The foam body 54 is adhesively joined to the rear of the foam body 52 . The foam body 54 is generally rectangular and includes the closed end channel 56 defined along a lateral edge. When the foam body 54 is adhesively joined to the foam body 52 , the channel 56 is adjacent with and in flow communication with the grooves 22 .

FIG. 6 shows a covering portion 54 a of the foam body pulled back so that the channel 56 can be seen. It will be understood that the foam body 54 defines part of the border 18 at the rear R of the mat 50 , with the fitting 14 extending therethrough for placement in flow communication with the channel 56 .

The disclosure advantageously enables lightweight disposable surgical suction mats having simplified construction with a relatively uniform and level upper surface on which the user can stand.

Turning to FIGS. 7-11 , there is shown an alternate embodiment of a surgical mat 60 according to the disclosure. The mat 60 is substantially similar to the mat 10 but includes additional features.

For example, the mat 60 includes a cut out 62 in the grooves 60 proximate the filter 24 to provide additional space in the collection channel 22 at the location of the filter 24 to enable utilization of a larger sized filter 24 in the collection channel 22 . This advantageously further increases the surface area of the filter and thereby further diffuse the vacuum to reduce noise.

The mat 60 also includes a construction of the edges 64 of the mat that is configured to provide a lower profile approach from the sides and rear of the mat 60 . For example, the lead-in chamfer on the edges 64 is elongated to provide a lower slope angle to reduce the potential for tripping when entering the mat 60 .

The mat 60 includes the grooves 20 which slope from the front F to the rear R of the mat 60 ( FIG. 10 ), as described in connection with the mat 10 to provide the sloped drain surfaces 20 a . However, in addition, the mat 60 also includes for the collection channel 22 a pair of oppositely sloped collection channel surfaces 66 that slope downward from lateral edges LE of the channel 22 to the location of the filter 24 , typically centrally located on the channel 22 , but, in any event, interior of the lateral edges of the channel 22 . The slope from the lateral edges to the interior location of the filter 24 promotes additional gravitational flow of fluids in the channel 22 to the filter 24 for suction removal.
