Descrição do estado da técnica Description of prior art
[002] Já são conhecidos oxímetros compreendendo uma unidade que se adapta ao dedo do paciente, a qual está provida de sensores de oxigenação do sangue e do batimento cardíaco. Um desses dispositivos, que se encontra descrito no documento de patente BR 10 2015 028372 5 intitulado "Oxímetro de Pulso sem Fio para Uso Contínuo'''' revela, em sua Fig. 1, uma unidade 10 em forma de pinça para instalação no dedo do paciente. Oximeters are already known comprising a unit that fits the patient's finger, which is provided with oxygenation sensors of the blood and heart rate. One such device, which is described in patent document BR 10 2015 028372 5 entitled "Pulse Oximeter Wireless for continuous use '' discloses in its Fig. 1, a unit 10 in the form of clamp for installation in finger of the patient.
[003] Apesar de tais unidades se destinarem a uso contínuo, sua utilização durante períodos prolongados, principalmente à noite, apresenta o risco de saírem do dedo, uma vez que sua retenção se deve apenas à pressão entre as faces internas da pinça e a pele do paciente.  Although such units are intended for continuous use, their use for prolonged periods, especially at night, presents the risk of getting out of the finger, since their retention is due only to the pressure between the internal faces of the tweezers and the skin of the patient.
[004] Numa tentativa de obviar tal inconveniente, é por vezes utilizada uma fita de esparadrapo circundando completamente o oxímetro e fazendo contato em ambas as faces externas. Tal procedimento, porém, é pouco preciso pois, além de não garantir a fixação, apresenta os seguintes problemas:  In an attempt to obviate such inconvenience, a tape of tape is sometimes used by completely surrounding the oximeter and making contact on both outer faces. This procedure, however, is not precise, as it does not guarantee fixation, it presents the following problems:
- Baixa eficiência da fixação;  - Low fixing efficiency;
- Desconforto;  - Discomfort;
- Difícil repetibilidade do processo de fixação;  - Difficult repeatability of the fixing process;
- Alta dependência da habilidade do operador; - Impossibilidade de assegurar que a pressão exercida pela pinça seja aquela especificada pelo fabricante do oximetro; - High dependence on the operator's ability; - Impossibility to ensure that the pressure exerted by the caliper is that specified by the manufacturer of the oximeter;
- Possibilidade de comprometimento da circulação periférica no caso da pressão aplicada resultar excessiva.  - Possibility of compromising the peripheral circulation in case the applied pressure proves excessive.

According to another feature of the utility model, the attachment of the oximeter to the patient's finger is provided by the juxtaposition of said extension to the finger and by a strap having semipermanent retention means, surrounding the finger with the extension thereto juxtaposed . According to another feature of the utility model herein proposed, the oximeter comprises at least one spring attaching the first and second portions of its housing, which presses said parts against each other providing the closure of said housing over the of the patient, without, however, collaborating to the retention of the oximeter.
Descrição das figuras Description of the figures
[0011] As demais vantagens e características do modelo proposto serão melhor entendidas através da descrição detalhada do mesmo e das figuras que a ele se referem, nas quais:  [0011] The other advantages and characteristics of the proposed model will be better understood through the detailed description thereof and of the figures relating thereto, in which:
[0012] A figura 1 é uma vista em perspectiva do oximetro afixado ao dedo do paciente.  Figure 1 is a perspective view of the oximeter affixed to the patient's finger.
[0013] A figura 2 é uma vista em elevação lateral ilustrando a posição do dedo dentro do oximetro.  Figure 2 is a side elevational view showing the position of the finger within the oximeter.
[0014] A figura 3 mostra a posição da mola com relação ao invólucro bipartido.  Figure 3 shows the position of the spring with respect to the two-part housing.
Descrição detalhada Detailed Description
[0015] A Fig. 1 mostra o oximetro 11, cujo invólucro compreende uma primeira parte 13 e uma segunda parte 14, encerrando entre elas o dedo 12 do paciente mediante compressão mútua entre ditas partes. A figura mostra ainda o prolongamento 15 em forma aproximada de meia-cana provido na extremidade proximal da dita primeira parte, com dimensões que proporcionam sua adaptação ao dedo.  1 shows the oximeter 11, which housing comprises a first portion 13 and a second portion 14, the patient's finger 12 enclosing therebetween by mutual compression between said portions. The figure further shows the approximate half-cane extension 15 provided at the proximal end of said first portion, with dimensions that provide for its adaptation to the finger.
[0016] A fixação do oximetro é provida por uma cinta 16 dotada de meios de retenção, a qual envolve o dedo 12 do paciente juntamente com o dito prolongamento 15 a ele justaposto. Ditos meios de retenção são selecionados dentre o grupo que compreende um adesivo, um botão de pressão ou um fixador tipo "velcro". The fixation of the oximeter is provided by a strap 16 provided with retaining means, which surrounds the patient's finger 12 together with said extension 15 which is juxtaposed thereon. Said retention means are selected from the group comprising an adhesive, a push button or a Velcro fastener.
[0017] A Fig. 2 é uma vista simplificada em elevação, onde está mostrada a posição do dedo 12 em linha tracejada dentro do oxímetrol 1, onde, para fins de clareza, não estão representados os sensores de oxigenação do sangue e do batimento cardíaco.  2 is a simplified elevational view where the position of the finger 12 is shown in dashed line within the oxymeter 1 where, for clarity, the oxygenation sensors of the blood and the heart beat are not shown .
[0018] Nessa figura, observa-se que a retenção do oxímetro 11 ao dedo 12 do paciente é provida exclusivamente pela compressão da cinta 16 que envolve no seu interior tanto o dedo 12 como o prolongamento 15 da primeira parte 13 do invólucro, cujas dimensões e curvatura permitem ajustar sua concavidade à convexidade do dedo. O arranjo ilustrado permite individualizar, separando-as, a funcionalidade de retenção e aquela referente à pressão do efeito pinça exercida sobre o dedo.  In this figure, it is observed that the retention of the oximeter 11 to the patient's finger 12 is provided exclusively by the compression of the strap 16 which envelops therein both the finger 12 and the extension 15 of the first part 13 of the housing, the dimensions and curvature allow you to adjust your concavity to the convexity of the finger. The illustrated arrangement makes it possible to separate the retention functionality and the one relating to the pressure of the clamp effect exerted on the finger.
[0019] A Fig. 3 mostra, em vista simplificada, uma das molas 17 que, além de unir a primeira parte 13 e a segunda parte 14 do invólucro, exercem uma força 18 que pressiona ditas partes uma contra a outra provendo o fechamento de dito invólucro sobre o dedo do paciente, sem, todavia, colaborar para a retenção do oxímetro.  3 shows, in simplified view, one of the springs 17 which, in addition to attaching the first part 13 and the second part 14 of the housing, exerts a force 18 which presses said parts against each other, providing the closure of said envelope on the patient's finger, without, however, collaborating for the retention of the oximeter.
[0020] Graças à nova disposição apresentada pelo modelo ora proposto, a pressão exercida sobre o dedo do paciente deixa de depender do grau de habilidade do operador. Evita-se destarte, tanto a possibilidade de uma pressão excessiva, que tenderia a prejudicar a circulação, como uma pressão insuficiente que poderia resultar em erros de leitura das condições fisiológicas monitoradas pelos sensores do oxímetro 11.  Thanks to the new provision presented by the model proposed herein, the pressure exerted on the patient's finger no longer depends on the skill level of the operator. Both the possibility of excessive pressure, which would tend to impair circulation, and an insufficient pressure that could result in errors in reading the physiological conditions monitored by the oximeter sensors 11 are avoided.
[0021] Com efeito, as molas 17, cujas características são determinadas durante a manuf atura do oxímetro pelo fabricante, garantem que a pressão mantenha um valor uniforme e predeterminado, independentemente do tempo em que o dispositivo ficar instalado no paciente e da habilidade do operador, assegurando a uniformidade das medidas e a confiabilidade dos resultados. Indeed, the springs 17, the characteristics of which are determined during manufacture of the oximeter by the manufacturer, ensure that the pressure maintains a uniform and predetermined value irrespective of the time in which the device is installed in the patient and the operator's ability, ensuring the uniformity of measurements and the reliability of the results.
