Abstract
Description
contexto da COVID-19 exige a avaliação do risco de produção de aerossol e consequente contaminação de profissionais de saúde e outros pacientes. Vale ressaltar que a capacidade do dispositivo minimizar esse risco deve ser considerada durante seu processo de escolha.
Listagem de sequências
A invenção trata-se de uma válvula para fluxo de oxigênio (7) oclusa por tampa quando inutilizada (8) localizada no dispositivo de entrada (6) que acoplada ao corpo do espaçador inalatório (1) que compreende um conduto (5) que se estende entre o dispositivo de entrada com orifício (2) para conexão a um nebulímetro dosimetrado que ao ser acionado permite ao usuário por meio do dispositivo de saída acoplado (3) antecedido por uma membrana unidirecional de fluxo (4) inalar o aerossol.
Claims (3)
- O espaçador inalador caracterizado por compreender um sistema com dispositivo de entrada para conexão de um dispersor aerossol que flui em direção ao orifício de saída antecedido por uma membrana unidirecional, a partir da qual o indivíduo pode inalar as partículas do medicamento pode gerar queda na saturação de Oxigênio durante sua utilização.
- A válvula de oxigênio caracterizada por uma entrada que permite o acoplamento de um sistema de circuito de oxigenioterapia, ocluída por tampa própria quando não utilizada, produzida em formato cônico triplo fundido garantirá a oferta de oxigênio ao paciente que fará uso diminuindo a desaturação.
- O espaçador inalador com válvula de oxigênio, de acordo com as reivindicações 1 e 2, caracterizado pelo acoplamento junto ao paciente com o fluxo de oxigênio tende a reduzir a dispersão de aerossol e garantir um adequado aproveitamento do fármaco.
