DESCRIPTION

Procedure for fixing a patient to an operating table when the patient is in the Trendelenburg position and for that purpose it includes a kit

Background

1. Technical field:

The present application is about a procedure for fixing a patient to an operating table when the patient is in the Trendelenburg position and an apparatus for this purpose. In US20100212087 such apparatus is disclosed.

2. Background information:

Background information is for informational purposes only and the information and publications mentioned below are not necessarily admitted to be the prior art.

The Trendelenburg position is used in operations of the lower body, such as the cervix. This position lowers the patient's head so that the legs and lower extremities of the body are elevated above the head. Often, the degree of descent is approximately ten degrees to twenty degrees, so that the head is maintained with the patient's back extending this range of angles below the lower part of the body. At certain times, the angle could be up to approximately forty-five degrees. The angle can be between about five degrees to about forty-five degrees in increments of one degree or in increments of fractions of one degree.

To minimize any injury to the patient on the table, various procedures have been used to hold the patient on the table. These procedures can injure the patient by providing unnecessary pressure to the neck, shoulders or arms, thereby aggravating the injury to the nerves and / or ulcers in the patient's body due to unnecessary pressure.

Object or objects

To reduce pressure points and pressures in small areas in the patient and also reduce these types of pressure to the patient's nerves, the present application describes a patient support apparatus as further disclosed in claim 1, a pad of Trendelenburg, a kit and procedures for using the Trendelenburg pad and a kit to reduce such pressures.

Summary

The pad is placed on a support table, such as a medical operating table, operating table or surgical table, so that the pad extends from the patient's buttocks area to the patient's shoulders and neck area . Straps are provided to hold the pad on the operating table, so that the pad does not move much during use. In addition, straps are provided to secure the patient to the operating table and place the patient firmly on the pad.

it is advantageous to orient the support or operating table and, therefore, the patient, with an inclination with respect to the horizontal. For medical procedures related to the lower part of the body, such as, for example, abdominal or gynecological operations, the Trendelenburg position can be used. This position involves a patient first lying horizontally on a support table. Then, the operating table or a portion thereof is tilted, so that the head and upper part of the patient's torso are vertically lower than the pelvic region and / or the patient's legs, as shown, for example, in Figure 6. In general, the support table is tilted so that the head and upper part of the patient's torso are lowered from the horizontal anywhere in a range of approximately five, ten or fifteen degrees to approximately twenty, thirty or forty-five degrees or more, in a steep Trendelenburg position, in increments of one degree or in increments of fractions of one degree. In addition to the positive Trendelenburg position, there is a negative or inverse Trendelenburg position, in which the head and upper torso are in a position vertically higher than the pelvic region and / or the patient's legs. As used herein, it should be understood that the phrase "Trendelenburg position" refers to both positions.

The present application discloses the use of a shape memory foam or a viscoelastic foam pad, as shown in Figure 1, to help hold the patient in a desired position on an inclined support table, such as in the Trendelenburg position, and help to minimize the patient's slippage, displacement or similar movements on the support table, movements that could be disturbing for a medical procedure that is being performed on the patient. The viscoelastic foam also cushions and supports the patient while promoting a distribution of pressure forces in the patient's body to reduce and / or minimize damage to nerves and / or tissue due to concentrated pressure forces. For example, viscoelastic foam will minimize or eliminate brachial plexopathy, including pain, less movement or less sensation in the arm and shoulder, minimizing pressure on the neck, arms and / or shoulders of the patient, and minimizing or thereby reducing a neuralgic episode. In at least one possible embodiment, the viscoelastic foam has characteristics that are selected to foster the preceding desired effects, which will be set forth in the following paragraph. All the features set forth in the following paragraph are according to at least one possible embodiment, and it should be understood that any one or more of the features could be combined with any one or more of the features according to at least one possible embodiment, and it should be understood that any interval disclosed in the following paragraph includes any value thereof, including increments of tenths and hundredths of the particular interval.

The recovery rate, that is, the time required for a viscoelastic foam to return to its initial form, is in the range of approximately 2-10 seconds for approximately 50 percent to 80 percent after deformation caused by placing an adult torso on a viscoelastic foam with a layer approximately 25.4 mm thick. The recovery rate is in the range of about 6-15 seconds for a recovery of about 80 percent to 90 percent after the same deformation as before. The recovery rate is in the range of approximately 10-35 seconds for a 100 percent recovery after the same deformation as before. The ball bounce of the viscoelastic foam is in the range of less than or substantially less than about one percent to about one percent or several percent units, or is in the range, or about in the range, of 0 , 1 percent up to 1.9 percent, or up to 3 percent or 5 percent, and up to several percentage units. The remanence to compression (the residual compression of the foam after twenty-two hours at seventy degrees Celsius) of the viscoelastic foam, for a compression of 25 percent of the foam, is in the range of less than one percent or tenths of a percentage unit, such as, for example, less than 0.4 percent or 0.3 percent, up to several percentage units. The compression retention of the viscoelastic foam, for a fifty percent compression of the foam, is in the range of less than one percent or tenths of a percentage unit, such as, for example, less than or equal at 0.5 percent, up to several percentage units. The deflection of the force of indentation of the viscoelastic foam, with a deflection of 25 percent, is in the range of several Newtons to tens of Newtons, such as in the range of approximately 44.4822 N to approximately 66.7233 N or in the range of about 31.13754 N to about 80.06796 N or is in the range of about 53.37864 N, such as, for example, 52.044, 52.48901, 52.9338, 53.37864, 53 , 8234, 54,2683, 54,7131, 55,1579 N. The coefficient of static friction between the viscoelastic foam and the surface of a support table is greater than 0.2, or is in the range of approximately 0, 2 or 0.5 to about 0.7 or 1.0. The viscoelastic foam is designed so that the patient can move on the viscoelastic foam less than 25.4 mm or up to approximately 25.4 mm or in the range of approximately 25.4 mm to approximately 76.2 mm. The air flow in the viscoelastic foam, or through it, is in the range of units of liters per minute to several tens of liters per minute, such as, for example, approximately 2831684.6 to 8495053.8 cubic mm per minute up to approximately 28316846.6 or 84950538 cubic mm per minute, or is in the range of about 15007928 cubic mm per minute, roughly 8495053.8 cubic mm per minute. The thickness of the viscoelastic foam is in the range from 19.05 mm to 25.4 mm, or up to approximately 25.4 mm or 38.1 mm or up to 76.2 mm or more, thickness that is selected to minimize and / or prevent one or more of the portions of a patient's body lying on the pad of

Viscoelastic foam bottoms on the operating table, depending on the weight and / or size of the patient. The tensile strength (with 25 percent deflection) of the viscoelastic foam is in the range of at least about 37.47 kPa or about 55.15 kPa to about 82.73 kPa or about 103.42 kPa, or in the range of approximately or equal to 68.94 kPa. The tear strength (in a 508 mm test per minute) of the viscoelastic foam is in the range of about one to about 8.8964 or 13,344 N or in the range of about 6.6723 N. The elongation (in a 508 mm per minute test) of the viscoelastic foam is in the range between 125 and 250 percent, or is in the range of approximately or equal to 172 percent, plus or minus 25 percent. The nominal density of viscoelastic foam is in a range of approximately 100 kilograms per cubic meter, or is in the range of approximately 75 or 83 kilograms per cubic meter to approximately 103 or 110 kilograms per cubic meter, such as, for example , 93.1 kilograms per cubic meter. The flammability of viscoelastic foam should pass various tests by CAL, FMVSS and FAR, and viscoelastic foam should exceed the European Union (EU RoHS) restriction standards for hazardous substances.

According to at least one possible embodiment, the viscoelastic foam pad can be of various lengths, and can extend well from the feet, either from the thighs or from a patient's buttocks either to the shoulders, either to the head or to the upper part of a patient's head. According to at least one possible embodiment, the viscoelastic foam pad or substantial portions thereof are pink, the straps for attaching the patient to the pad are lilac, and the straps for attaching the pad to the table or surface are white

As shown in Figure 1, a Trendelenburg pad 102 may comprise fasteners 104 that extend beyond the longitudinal sides of the Trendelenburg pad 102. Each end of the fasteners 104 may comprise a hook and loop fastener, such as a Velcro® fastener, configured and arranged to secure the Trendelenburg pad 102 to rails of the operating table or other adjacent structures, depending on the structure of support on which the patient is placed, which may or may not be an operating table. For example, each end of a fastener 104 may comprise a loop portion 108 and a hook portion 106, which extends beyond the loop portion 108. In addition, one or more portions of the fasteners 104 extending beyond the Trendelenburg pad 102 may comprise a tag 110 indicating the orientation of the Trendelenburg pad 102 with an operating table. For example, tag 110 may indicate "this side up."

In at least one possible embodiment of the present application, the Trendelenburg pad 102 may be a disposable pad and / or a single use pad.

Figure 2 shows a bottom view of a Trendelenburg pad 102 comprising fasteners 104 that extend latitudinally therewith. A central portion 112 of the fasteners 104 may be configured to be fixed with the Trendelenburg pad 102. For example, the central portion 112 may comprise hooks configured and arranged to be fixed with loops on the Trendelenburg pad 102. The Trendelenburg pad 102 may be configured to be fixed with two or more fixings 104. The fasteners may be Velcro®.

Figures 3A and 3B show a top view and a side view of a fixation 104, respectively. A central portion 112 of the fastener 104 may comprise loops on one side configured to be fixed with hooks in a Trendelenburg pad 102, as shown in Figure 2. A weld 115 can fix a hook portion 108 and a loop portion 106 to the central portion 112, wherein the ends of the fastener 104 comprise a hook portion 108 and a loop portion 106. It should be understood that the portion 108 or 106 may comprise hooks and the other portion 108 or 106 may comprise loops. A tag 110 can be attached to an upper side of the hook portion 108. One end of the hook portion 108 can be folded and welded at a weld point 111 to form a flange 109. The hooks 113 can extend from a bottom surface of the hook portion 108. Loops 107 may extend from a lower surface of loop portion 106.

Figure 4 shows a use of the Trendelenburg pad 102. For example, Trendelenburg pad 102 may be used:

1. Placing a surgical operating table 120, which has surgical operating table 120 rails, in a lithotomy position.

2. Placing a longitudinal distal end of the Trendelenburg pad 102 on a longitudinal distal end of the surgical operating table 120.

3. Centering latitudinally the pad 102 of Trendelenburg with the table 102 of surgical operations.

4. Placing the straps 104, which extend from the longitudinal edges of the Trendelenburg pad 102, lowering, away from the place where a patient 128 will be lying.

5. Attaching the straps 104 to the surgical operating table rails 124.

6. Extending a transfer sheet 126 over pad 102 of Trendelenburg.

7. Lay a patient 128 on the Trendelenburg pad 102 by placing the patient 128 so that the patient's shoulders do not extend beyond the edges of the Trendelenburg pad 102.

8. Lifting the transfer sheet 126, thereby lifting the patient 128 up and away from the Trendelenburg pad 102 to reposition the patient 128, as necessary.

9. Placing the patient's arms, as necessary.

10. Fixing straps 130 for the body around the patient and the surgical operating table.

11. Fixing the patient's legs in stirrups 122.

12. Placing the surgical operating table in the Trendelenburg position.

In at least one possible embodiment of the present application, a patient may be placed on a Trendelenburg pad 102, so that the patient's skin makes contact with the Trendelenburg pad 102, for example that the patient's skin makes contact with the Trendelenburg pad 102 in the sacral and scapular areas of the patient's body and be held by Trendelenburg pad 102. The transfer sheet 126 may be used and the patient replaced without dragging the patient through the Trendelenburg pad.

Also shown in Figure 4 are straps 130 for the body. The body straps 130 may comprise a hook strap 132 and a loop strap 134, such as a Velcro® strap. Each hook strap 132 and each loop strap 134 may comprise a buckle at one end. A hook strap 132 can be attached to a rail 124 of the operating table by winding it around it and extending through the buckle. A loop strap 134 can be attached to the other rail 124 of the operating table by winding it around it and extending through the buckle, or fixing it by extending the hook strap 132 around some other portion, or even thereto, from the operating table. The hook strap 132 and the loop strap 134 can be fixed around a patient 128, holding the patient 128 to the Trendelenburg pad 102. It should be understood that the straps 130 for the body are optional since the Trendelenburg pad 102 can provide adequate support of the patient 128 on a table 120 of surgical operations.

Figure 5 shows a Trendelenburg pad 102 having a mark or residual compression 130 of a patient therein. Trendelenburg pad 102 comprises viscoelastic foam that adapts to the patient's body and adapts itself to support the body. This form minimizes pressure points in the body and helps hold the body on the operating table.

The quality or holding capacity between the Trendelenburg pad and a patient will be a combination of the coefficient of friction between the patient and the viscoelastic foam and the retention capacity of the brand created by the patient in the viscoelastic foam, because the pad Trendelenburg is made of a viscoelastic foam in which a mark is formed and held in the foam for at least a time after the patient is moved from one position to another or from the operating table (see Figure 5 ). The equivalent total friction characteristic, which includes friction due to friction coefficient and friction force or similar to friction due to deformation of viscoelastic foam, may be equal to or greater than one. That is, the normal perpendicular force to the viscoelastic pad resulting from the patient's body and the component of the force of gravity on the patient parallel to the surface of the operating table at forty-five degrees are equal, which means that the characteristic Total equivalent friction will be equal to or greater than the normal perpendicular force. For an angle of forty-five degrees, the equivalent total friction characteristic is one, which is [sin 45 ° / cos 45 °]. Stated more generally, the equivalent total friction characteristic would be greater than the sine of the angle of inclination with respect to the horizontal divided by the cosine of the angle of inclination with respect to the horizontal. Since the angle can vary in increments of one degree or less, the range of values of the equivalent total friction characteristic could vary between any of those angles, so that it is at least the values of the sine divided by the cosine of each of these angles of inclination or greater, at least within the range of degrees greater than zero to forty-five degrees and also somewhat above forty-five degrees and even greater. The holding capacities are a combination of the holding capacity of the pad, of the body straps and the coefficient of friction of the pad with respect to the patient and the table, between the pad and the sheet between the pad and the patient , and between the sheet and the patient, for all the angles described.

Figure 6 shows a Trendelenburg pad 102 of the present application attached to a surgical table 120 with fixings 104. A patient 128 is placed on the Trendelenburg pad 102, and the surgical operation table 120 is in the position of Trendelenburg Also shown in Figure 6 is an aspect of the Trendelenburg pad 102 in which the straps 130 for the body are not needed to hold a patient 128 on the surgical operation table 120 in the Trendelenburg position.

Figure 7 is a computer illustration of a person disposed on a Trendelenburg pad of a possible embodiment of the present application. The person's silhouette is transparent or translucent, allowing

a vision of the brand on the Trendelenburg pad created by the person's silhouette. The Trendelenburg pad mark can provide the primary support to hold a person on the operating table depending on the patient's angle on the table.

When a table with an angle of forty-five degrees is tilted, if W is the weight of a patient, the normal force perpendicular to the surface of the operating table is 0.707W. The force along the table is 0.707W. The equivalent coefficient of friction includes the actual coefficient of friction and the holding capacity of the Trendelenburg pad and of the fasteners 130 of the present application for restraining a patient is 1.00.

The positioning provision and the provisions in the present application could be used in gynecological procedures, in colorectal procedures, in urological procedures, in laparoscopic procedures and in robotic procedures by naming some procedures for using this pad in the Trendelenburg position or in the position inverse of Trendelenburg or in laterally inclined positions. The positioning arrangement and embodiments of the Trendelenburg pad and the kit could also be used in the present application in all types of medical procedures in which it may be desirable to place a patient in a fixed position and / or point reduced and / or comfortable pressure, medical procedures that include surgical procedures and non-surgical procedures, such as explorations and / or non-surgical treatments.

The viscoelastic foam of the present application can be a polyurethane foam made by mixing polyhydroxy polyol with toluene diisocyanate or other and various methods, as is known in the art. For example, toluene diisocyanate can be used in combination with polyester and polyether polyols to make viscoelastic foam.
