Description

"PLACA COMPONENTE DE SUPORTE PARA TRANSDUTOR DE PRESSÃO  "PRESSURE TRANSDUCER SUPPORT COMPONENT BOARD
DESCARTÁVEL"  DISPOSABLE"
Campo da Invenção  Field of the Invention
A presente invenção trata de uma placa utiliza em um suporte para transdutor de pressão descartável. Mais especificamente, trata de uma placa utilizada em sistema de monitoração de pressão, que consiste em uma peça sustentada por uma garra para fixação à haste de sustentação de embalagens de soro, podendo compreender uma ou mais placas para transdutor de pressão e os respectivos transdutores descartáveis.  The present invention deals with a plate used in a disposable pressure transducer holder. More specifically, it is a plate used in a pressure monitoring system, which consists of a piece supported by a clamp for attachment to the serum packaging support rod, and may comprise one or more pressure transducer plates and their disposable transducers. .
Histórico da Invenção  Invention History
A maioria dos suportes para transdutores de pressão descartáveis existentes no mercado consiste em uma placa que pode ser para um ou mais transdutores, afixada a uma garra que, por sua vez, é afixada ao suporte de soro. O transdutor descartável fica encaixado a essa placa e o cabo de interface é encaixado ao cabo do transdutor descartável, ficando este pendurado pelo conector. Para identificar os diferentes canais de pressão que podem ser utilizados simultaneamente, são utilizadas etiquetas coloridas feitas de papel.  Most commercially available disposable pressure transducer holders consist of a plate that can be for one or more transducers attached to a jaw which is attached to the serum holder. The disposable transducer fits into this card and the interface cable fits into the disposable transducer cable, which hangs from the connector. To identify the different pressure channels that can be used simultaneously, colored labels made of paper are used.
Ocorre que a baixa durabilidade dos referidos cabos de interface e a falta de confiabilidade nas conexões são os maiores problemas relativos aos sistemas disponíveis atualmente. Pelo fato de os cabos ficarem pendurados ao transdutor pelo conector, a conexão fica suscetível à trações devido a puxões ou esbarrões acidentais de médicos, enfermeiros e do próprio paciente quando se movimenta no leito ou acomodação que está utilizando. Até mesmo o próprio peso dos cabos de interface provoca certa tração que, com o tempo, favorece sua desconexão ou rompimento. Esses problemas evidentemente acarretam falhas de contato ao longo do tempo, prejudicando de forma direta o acompanhamento das condições do paciente, além de provocar danos irreparáveis aos conectores do cabo ou do transdutor, o que requer suas substituições e acarreta em aumentando do custo de operação e de manutenção do sistema. Ainda outro problema bastante comum apresentado pelos suportes do estado da técnica é aquele relacionado com a posição dos cabos, que em caso de vazamento de soro haverá grande possibilidade de molhar o conector e com isso o danificar, prejudicando ou até mesmo impedindo o funcionamento adequado do transdutor de pressão. The low durability of these interface cables and the lack of reliability in the connections are the biggest problems related to the systems available today. Because the cables are hanging from the transducer by the connector, the connection is susceptible to traction due to accidental pulling or bumping of doctors, nurses, and the patient himself when moving in the bed or accommodation he is using. Even the very weight of the interface cables causes some traction that, over time, favors their disconnection or breakage. These problems evidently cause contact failures over time, directly impairing the patient's condition monitoring, as well as causing irreparable damage to the cable or transducer connectors, requiring their replacement and increasing the cost of operation and maintenance. system maintenance. Still another very common problem presented by the supports of the state of the art is that related to the position of the cables, which in case of leakage of serum will have a great possibility of wetting the connector and thus damaging it, impairing or even preventing the proper functioning of the connector. pressure transducer.
Adicionalmente, referidos suportes do estado da técnica apresentam problemas com as etiquetas de identificação neles utilizadas, que geralmente são confeccionadas em papel, estando, portanto, sujeitas à deterioração precoce. Isso ocorrendo, haverá dificuldade de identificação dos canais de pressão pelos profissionais médicos e enfermeiros, acarretando em dúvida e confusão que podem, evidentemente, ocasionar erros no manuseio do sistema e/ou na interpretação de resultados.  Additionally, such prior art carriers have problems with the identification labels used therein, which are generally made of paper and are therefore subject to early deterioration. This will cause difficulties in the identification of pressure channels by medical professionals and nurses, leading to doubt and confusion that can, of course, lead to errors in the handling of the system and / or interpretation of results.
Assim, constatado essa inadequação dos dispositivos do estado da técnica, foi desenvolvido um sistema de monitoração de pressão que adota o conceito de estação de trabalho. Cada estação de trabalho consiste em uma peça em forma de garra para fixação à haste de sustentação de embalagens de soro, uma ou mais placas para transdutor de pressão e os respectivos transdutores descartáveis.  Thus, finding this inadequacy of state of the art devices, a pressure monitoring system was developed that adopts the concept of workstation. Each workstation consists of a claw-shaped piece for attachment to the serum packaging support rod, one or more pressure transducer plates and their disposable transducers.
