THORACICAL SAFETY AND RETAINING DEVICE FOR PATIENTS AND TENSOR ELEMENT ASSOCIATED WITH THE SAME

DESCRIPTION

Field of the Invention

The present invention relates to a safety and thoracic retention device for agitated and / or aggressive patients, as well as to a tension element associated therewith, especially applicable in the emergency health and / or mental health field. 10

Background of the invention

Thoracic retention devices should be used as a last resort during the mechanical containment of agitated and / or aggressive patients according to hospital protocols, guaranteeing at all times the safety of the patient, of the health personnel and of third parties. In addition, they must always take into account a continuous supervision of the patient, a correct placement of the patient on the bed or stretcher in which the containment is carried out, as well as a correct use of the device during the agitation episode and / or the waits for pharmacological containment to act. Once the agitation disappears, the device must be removed with maximum speed.

Currently, various devices for the mechanical containment of this type of patients are known. One of the most representative is SALVAFIX®. It consists of a “¥” shaped chest harness that is attached to an abdominal belt at the back of the patient by velcro® through a fabric buckle. Then it goes up the dorsal area to a transverse belt or webbing, previously fixed to the bed frame by means of magnetic fasteners. Said ribbons surround the patient through each clavicular area joining each other in front of the neck in the form of a "blade" by means of a magnetic fixation element, another tape that serves as an extension and that rises towards the neck from the ventral area of the abdominal belt. This "¥" shaped webbing also has two "Y" sewn webbing with the function of circling the patient's chest at the height of the floating ribs and joining the extension that rises from the ventral area of the abdominal containment in another fixing point by means of a magnetic fixing element, located below, to which the belts or straps are connected with

"blade" shape. Once these magnetic elements have been closed, they cannot be opened manually, but require the use of specific tools.

This type of device has several drawbacks, both for the patient and for the healthcare staff. 5

As far as the patient is concerned, it should be noted that the thoracic retention is carried out through the use of two retention straps that, in a crossed way, extend each of them from the patient's abdominal area to the clavicular area near his neck. So, said retention straps can end up passing very close to the softer parts of the neck, putting the patient at risk. In addition, all tapes, bands and / or straps that use this type of device have flat and rigid surfaces that can be uncomfortable for the patient.

 fifteen

As for health personnel, it should be noted that the main problems arise during the placement of the device, and more especially when it is necessary to tighten the fixing straps and the type of stretcher does not allow it due to the lack of access to the frame, and You have to proceed to the union of its ends. This is due to the great diversity of widths, shapes and sizes presented by said support bases (beds, stretchers, etc.), as well as the thickness and fluffiness of the mattresses used thereon. As an example, those used in ambulances can be between 50 and 60 cm wide, between 70 and 80 cm in hospital beds, and more than 90 cm in beds. Therefore, when tensioning the fixing straps, the health personnel must manually pull them tightly, often in quite awkward positions due to lack of space (especially in ambulances and in boxes with beds attached to the wall), and with the patient acting against it, so that the device is firmly attached to said support base. It usually happens on many occasions that, once the magnetic fixing element is arranged, the fixing straps are not sufficiently tight to the bed or stretcher, giving a certain mobility to the patient that may jeopardize their safety and / or that of third parties , for example, giving headers to the railings, wall or sanitary personnel.

Another complication more than the existing ones, is the difficulty in the placement of the chest harness by the different parts that compose it and the risk of injuries perceived by the

health personnel having straps that pass very close to the soft tissue area of the neck when the patient is violently incorporated. In addition to the need to have magnetic keys and sufficient material for containment available at all times, to be able to quickly release the patient, in case of vital risk. 5

The present invention solves the problems described above by means of a safety and thoracic retention device for agitated and / or aggressive patients, as well as a tension element associated therewith, whose configuration allows the connection of a tension element to be carried out in the first place. a quick union of 10 both fixing straps, and secondly a progressive or gradual adjustment of the tension of the same on the bed or stretcher until reaching the desired tension, allowing later to join the ends thereof to release said tensioning element and reuse it on another device. In turn, the configuration of the harness that incorporates the device of the present invention also favors its correct disposition on the patient, avoiding risks for the same and ensuring its adequate containment and release in case of emergency of vital risk in a more comfortable way, Fast and safe, using a single magnetic fixation element that does not interfere with the rapid release of agitated / aggressive patients.

Detailed description of the invention

Figure 1 shows a view of the thoracic safety and retention device (1) for agitated and / or aggressive patients of the present invention arranged on a bed or stretcher (C). 25

As can be seen, said device (1) comprises:

- a retention harness (2) configured to fit the upper part of a patient's back (P);

- a first fastening tape or strap (3) that extends laterally from the retaining harness (2), and which has a first connecting end (31); Y

- a second fixing strap or strap (4) that extends laterally from the retaining harness (2) in the opposite direction to the first fixing strap (3), and which has a second attachment end (41);

where both joining ends (31, 41) are configured to join 35

each other around a bed or stretcher (C) on which the patient is disposed (P).

Said device (1) is characterized in that the second fixing strap (4) comprises an auxiliary end (5) for connecting a tensioning element (6), figure 4, in turn connected to the first connecting end (31) of the first fixing tape (3), allowing 5 to gradually tension the fixing bands (3, 4) around the bed or stretcher (C), figures 5 and 7.

In turn, the retention harness (2) comprises a back band or base (21) configured to fit on the patient's back (P), which has:

- a first side (21a) of which the first fixing tape (3) extends laterally; Y

- a second side (21b), opposite the first side (21a), from which the second fixing tape (4) and the auxiliary end (5) are laterally extended.

 fifteen

As can be seen in Figures 2 and 3, the retention harness (2) comprises a first retention strap (22a) and a second retention strap (22b) arranged in parallel, separated for example between 15 and 25 cm, configured to fit around the patient's acromioclavicular joints (P), figures 5 and 7. Likewise, the first retention strap (22a) comprises a first end of 20 adjustment (23a) to which it is attached by a first rotating joint (24a) a first rapid adjustment element (25a); while the second retaining strap (22b) comprises a second adjustment end (23b) to which a second rapid adjustment element (25b) is connected by means of a second swivel joint (24b). Said rotating joints (24a, 24b) allow the retention belts (22a, 22b) to better adapt to the pseudocircular shape of the acromioclavicular zone.

As an example, the retaining straps (22a, 22b) can each have a length of 80 cm and a width of approximately 2.5 cm. In turn, the rapid adjustment elements (25a, 25b) can be of the Velcro® male type of approximately 30-15 cm in length, also contributing to improving said adaptation.

In turn, the first retaining strap (22a) extends perpendicularly from the rear band (21) from a first fixed joint (26a), figure 1, integral with said

rear band (21) and opposite the first quick adjustment element (25a); while the second retaining strap (22b) extends perpendicularly from the rear band (21) from a second fixed joint (26b), figure 1, integral with said rear band (21) and opposite to the second rapid adjustment element (25b ). Also, the rear band (21) comprises a first fastening strip (27a) enabled to 5 allow the passage of the first adjustment end (23a) between said first fastening strip (27a) and the rear band (21); and a second fastening strip (27b) enabled to allow the passage of the second adjustment end (23b) between said second fastening strip (27b) and the rear band (21).

 10

The first retention strap (22a) and the second retention strap (22b) respectively comprise a first padded liner (28a) and a second padded liner (28b) for patient protection (P). Thus, being “foamized” the retention straps (22a, 22b) give the patient greater safety and comfort, and also facilitate the fixation of the rapid adjustment elements 15 (25a, 25b) of Velcro® type, figures 5 and 7. By way of example, the padded coverings (28a, 28b) can each have a length of approximately 70 cm of "foam" fabric.

The first fixing tape (3) and the second fixing tape (4) respectively have a first length (3L) and a second length (4L); where the second length (4L) is less than the first length (3L). For example, the first length (3L) can be about 120 cm, while the second length (4L) can be about 20 cm. This allows the point of attachment not to be just under the bed or stretcher (C), but on one side of the bed above the mattress, figures 5 and 25 7. So that the time and effort of the placement on the stretcher (C) by the health personnel, since it is not necessary for it to get under it to join both tapes (3, 4). In turn, the width of each tape (3, 4) can be, by way of example, about 2.5 cm.

 30

The first connecting end (31) and the second connecting end (41) respectively comprise first holes or adjustment eyelets (32) and second holes or adjustment eyelets (42) configured to coincide with each other, allowing the passage of an element fixing (7) between two matching adjustment holes (32, 42) to join both joining ends (31, 41). 35

The holes (32, 42) can be distributed at various points along the fixing straps (3, 4) to adapt to the different types of beds and stretchers (C). For example, the first fixing tape (3) can have a first group of first adjustment holes (32), not illustrated, about 60 cm from the first side (21a) of the rear band (21) for use in ambulance stretchers, and a second group of 5 first adjustment holes (32) from about 80 cm from the first side (21a) of the rear band (21) for use in hospital beds. The adjustment holes (32, 42) can be arranged in line along the fixing straps (3, 4), for example, every 4 cm.

 10

According to the present example, the auxiliary end (5) comprises a section of auxiliary belt or webbing (51), about 5 cm long by 2.5 cm wide, whose end has a first quick-release and quick-release element (52), buckle type female closure, sewn to said auxiliary tape (51).

 fifteen

As can be seen in Figure 4, the device (1) comprises a tension element (6) of the ratchet type which has a connector end (61) for connection to the auxiliary end (5) and an adjustment end (62) for its connection to the first connecting end (31). Said connector end (61) is formed by a section of tape or webbing (63) of about 20 cm, which extends from the tensioning element (6) to a second 20 quick-release and quick-release element (64), buckle type male closure complementary to the first quick-release and snap-in element (52). These quick-release and quick-release elements (52, 64) allow the tensioning element (6) to be released once the fixing straps (3, 4) have been tensioned, after joining both joining ends (31, 41), in order to use the tension element (6) in another 25 patients.

The tensioning element (6) allows the device (1) to be adjusted to the bed or stretcher (C) to save the sponge of the mattress, adjusting the patient set (P) - bed or stretcher (C) more firmly. 30

Figures 5 and 6 show respectively a mode of application of the device (1) of the present invention and a detail thereof, before proceeding to the union of the connecting ends (31, 41) of the fixing tapes (3, 4).

 35

As can be seen, the auxiliary end (5) is connected to the tensioning element (6), in turn connected to the first connecting end (31) of the first fixing tape (3). This allows to gradually tighten the fixing straps (3, 4) around the bed or stretcher (C). When the desired tension is reached, it is automatically maintained due to the tension exerted by the tensioning element (6). At that time, healthcare personnel can easily and effortlessly join the joining ends (31, 41) of both fixing straps (3, 4). To do this, you can use a single magnetic fixing element (7) formed by two magnetized pivots that join together through matching adjustment holes (32, 42).

 10

Figures 7 and 8 show respectively a mode of application of the device of the present invention and a detail thereof, after proceeding to release the tensioning element (6). Said process is carried out in an easy and comfortable way, simply by unhooking the first quick-release and quick-release element (52) of the female-type buckle type, of the second quick-release and quick-release element 15 (64) of the male-type buckle type.

It should be added, in view of the mode of application shown in Figures 5-8, that in relation to patient safety (P), the exposure of the patient's chest (P) to access it is improved with respect to known devices for both medical examination and monitoring. This also constitutes a vital security element, since it does not interfere with normorespiration, since no tape surrounds the patient's chest (P), thus making it impossible to suffocate due to tightening too much.

On the other hand, as previously mentioned, monitoring of the patient (P) 25 content is mandatory according to hospital protocols due to the possibility of lethal arrhythmias due to the sustained increase in heart rate and cardiotoxic substances or respiratory system depressants, which I could have consumed before the episode of agitation / violence. As well as pharmacological adverse effects of iatrogenic origin. 30

Profuse sweating caused by high physical exertion during agitation, ambient temperature and drugs that raise body temperature play against the electrodes used to monitor the patient as they detach from the patient's chest or give errors. In this sense, the device (1) of 35

Thoracic safety and retention of the present invention contemplates the possibility of implementing sensors (100) in contact with the skin, subject to the same device (1), which allows the information to be sent without wires, to a receiver (101) that would show it on a monitor located in the nursing control area in real time.

 5

In addition, according to hospital protocols, a person in mechanical containment has to be supervised at least every 15 minutes. During that time, the thoracic safety and retention device (1) of the present invention, being held by the patient's acromioclavicular zone (P), allows the placement of an accelerometer in order to count the number of scapular movements and thus be able to determine the level 10 of psychomotor agitation, with the aim of being able to justify its withdrawal when the agitation ceases, or to notify the physician to assess the administration of relaxing rescue drugs.
