Description

DISPOSITIVOS 1NMOVILIZADORES TEMPORALES Y DESECHABLES DEL TIPO FÉRULAS ORTOPÉDICAS TEMPORARY AND DISPOSABLE MOVEMENT DEVICES OF THE ORTHOPEDIC SPLITS TYPE
La presente invención se desarrolla en el campo de Ia medicina. Particularmente, Ia presente invención proporciona novedosos dispositivos inmovilizadores temporales y desechables del tipo férulas ortopédicas para Ia inmovilización de cuello, brazos y piernas, cuando estos han sufrido de lesiones y requieren de atención pre-hospitalaria y de primeros auxilios.The present invention is developed in the field of medicine. Particularly, the present invention provides novel temporary and disposable immobilizer devices of the orthopedic splints type for the immobilization of the neck, arms and legs, when they have suffered from injuries and require pre-hospital care and first aid.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Es bien sabido que los accidentes de transito en Colombia constituyen un grave problema de salud pública que siguen siendo un factor alarmante para Ia sociedad, dado que generan consecuencias como Ia muerte de Ia victima o alteraciones graves de bienestar en los sobrevivientes. Entre estas alteraciones se encuentran las lesiones cervicales y las producidas en los miembros superiores e inferiores, las cuáles pueden llevar a una discapacidad temporal o definitiva del paciente. Bajo estas circunstancias, es de gran importancia el manejo que se Ie brinde a tales lesiones durante Ia atención inicial o pre-hospitalaria, o de primeros auxilios. En general, el personal responsable de Ia atención de estas lesiones sabe muy bien que en el momento que se producen, tanto el cuello como las extremidades constituyen partes del cuerpo inestables que deben ser inmovilizados de manera eficiente para facilitar su desplazamiento y evitar complicaciones posteriores.It is well known that traffic accidents in Colombia constitute a serious public health problem that continue to be an alarming factor for society, given that they generate consequences such as the death of the victim or serious disturbances of well-being in the survivors. Among these alterations are cervical lesions and those produced in the upper and lower limbs, which can lead to a temporary or definitive disability of the patient. Under these circumstances, the management provided to such injuries during initial or pre-hospital or first aid care is of great importance. In general, the personnel responsible for the care of these injuries know very well that at the time they occur, both the neck and the extremities constitute unstable parts of the body that must be immobilized efficiently to facilitate their displacement and avoid subsequent complications.
Actualmente se dispone de una variedad de dispositivos inmovilizadores que sirven para los propósitos de inmovilizar cuello y extremidades en caso de sufrir traumas. Por ejemplo, en el caso de inmovilizaciones del cuello existen varios dispositivos del tipo férulas, tales como los collares conocidos comúnmente como cuellos "Filadelfia" y "Ambú o multitalla". Sin embargo, es bien sabido que dichos collares son muy costosos Io que limita significativamente su uso. Por ejemplo, en cada ambulancia solamente se dispone de dos a tres collares, y esta situación los hace incapaces de suplir las necesidades en caso de eventos masivos o catástrofes. La misma situación ocurre en los diferentes centros hospitalarios, clínicas y centros de primeros auxilios. De esta manera, en caso de un accidente, o una situación masiva de pacientes con lesiones, el organismo de atención pre-hospitalaria tiene que esperar Ia devolución de los inmovilizadores por parte de Ia clínica o el hospital al que se desplazó el herido. Estas esperas normalmente son muy prolongadas debido a que los pacientes tardan en ser evaluados mientras se llevan a cabo todos los procedimientos médicos necesarios para el diagnóstico y tratamiento de las lesiones, Io cuál retarda considerablemente Ia devolución de las férulas que se hayan utilizado en los pacientes. Esta situación conlleva a generar largas esperas, en ocasiones fatales para los equipos de atención pre-hospitalaria (ambulancias, médicos, paramédicos etc.) mientras se recibe el retorno de los mismos; y además es posible que los pacientes se encuentren expuestos a infecciones o molestias por el uso masivo de los inmovilizadores, dado que los materiales de los cuales están fabricados estos dispositivos no son los adecuados para permitir Ia correcta transpiración de los tejidos. Adicionalmente, en países como el nuestro, donde los recursos son limitados, no es posible desechar estos elementos cada vez que se atiende un accidente debido al costo elevado que esto implica para los organismos de emergencia y primera respuesta.A variety of immobilizer devices are currently available that serve the purposes of immobilizing neck and limbs in case of suffer trauma For example, in the case of neck restraints there are several splint-type devices, such as collars commonly known as "Philadelphia" and "Ambú or multitalla" collars. However, it is well known that such collars are very expensive, which significantly limits their use. For example, in each ambulance only two to three collars are available, and this situation makes them unable to meet the needs in case of massive events or catastrophes. The same situation occurs in different hospitals, clinics and first aid centers. Thus, in case of an accident, or a massive situation of patients with injuries, the pre-hospital care agency has to wait for the return of the immobilizers by the clinic or the hospital to which the injured person moved. These waits are usually very prolonged because patients take time to be evaluated while all the necessary medical procedures for the diagnosis and treatment of injuries are carried out, which considerably delays the return of splints that have been used in patients . This situation leads to generating long waits, sometimes fatal for pre-hospital care teams (ambulances, doctors, paramedics, etc.) while receiving their return; and it is also possible that patients are exposed to infections or discomfort from the massive use of immobilizers, given that the materials from which these devices are manufactured are not adequate to allow the correct perspiration of tissues. Additionally, in countries like ours, where resources are limited, it is not possible to discard these elements every time an accident is attended due to the high cost that this implies for emergency and first response agencies.
De igual manera, el elevado costo de los inmovilizadores de plástico, polipropileno y resinas disponibles en el mercado, dificulta su implementación en lugares e instituciones como colegios, hoteles, clubes deportivos, gimnasios, fuerzas armadas y vehículos de transporte público, escolares y particulares, donde es frecuente Ia ocurrencia de accidentes menores que, en todo caso, pueden involucrar lesiones que requieran atención especial e inmediata. A las circunstancias anteriores se suma el hecho de ser elementos de mucho peso y excesiva rigidez, por Io cual ocupan mucho espacio, dificultando su transporte y almacenamiento.Similarly, the high cost of plastic, polypropylene and resins immobilizers available in the market makes it difficult to implement in places and institutions such as schools, hotels, sports clubs, gyms, armed forces and public transport vehicles, schoolchildren and individuals, where the occurrence of minor accidents that, in any case, may involve injuries that require special and immediate attention. In addition to the above circumstances, the fact of being elements of great weight and excessive rigidity, which occupy a lot of space, hindering its transport and storage.
Finalmente, existe otro tipo de ¡nmovilizadores disponibles actualmente en el mercado, que se caracterizan por ser inflables, de manera que permiten una mayor facilidad de transporte y almacenamiento, al paso que se pueden ajustar a todos los miembros. Sin embargo, estos inmovilizadores, al igual que los otros elaborados en materiales como el plástico, el polipropileno o varios tipos de resinas, exhiben serias desventajas por los altos costos del material y su elaboración.Finally, there are other types of immobilizers currently available in the market, which are characterized by being inflatable, so that they allow greater ease of transport and storage, while all members can be adjusted. However, these immobilizers, like the others made in materials such as plastic, polypropylene or various types of resins, exhibit serious disadvantages due to the high costs of the material and its preparation.
Es claro entonces que los inmovilizadores disponibles actualmente en el mercado exhiben desventajas significativas, dado que son muy costosos, Io cual limita su disponibilidad en ambulancias, hospitales, colegios, etc.; además se elaboran en materiales que no permiten Ia transpiración de los tejidos lesionados; algunos de ellos son elaborados en materiales radio opacos, y por Io tanto, al momento de tomar las radiografías, es necesario retirarlos con Ia consecuente molestia para el paciente.It is clear then that the immobilizers currently available in the market exhibit significant disadvantages, since they are very expensive, which limits their availability in ambulances, hospitals, schools, etc .; They are also made of materials that do not allow the perspiration of injured tissues; some of them are made of opaque radio materials, and therefore, at the time of taking the radiographs, it is necessary to remove them with the consequent discomfort for the patient.
Por consiguiente, es claro que aún existe en el estado de Ia técnica Ia urgente necesidad de un novedoso dispositivo temporal y desechable para Ia inmovilización de cuello y extremidades que sea efectivo en su propósito de inmovilización de dichas partes en caso de sufrir lesiones; que además reduzca de manera significativa los costos de fabricación, y mejore significativamente otros aspectos técnicos asociados con este tipo de dispositivos. DESCRIPCIÓN DE LAS FIGURASTherefore, it is clear that there is still an urgent need in the state of the art for a new temporary and disposable device for immobilization of the neck and extremities that is effective in its purpose of immobilization of said parts in case of suffering injuries; which also significantly reduces manufacturing costs, and significantly improves other technical aspects associated with this type of device.
