The invention relates to the technical field of oxyhemoglobin saturation sensors, in particular to a deformation elastic piece and a multi-position oxyhemoglobin saturation sensor formed by the deformation elastic piece.
Background
The basic principle of the blood oxygen saturation sensor is as follows: a light generating element is arranged to generate infrared light and red light, and after the infrared light and the red light penetrate through certain tissues of a human body, a light receiving element senses the infrared light and the red light and calculates an electric signal corresponding to the light, so that the blood oxygen saturation is finally obtained.
The conventional oximetry sensor is generally a clip structure composed of a lever and a spring, wherein a light generating element and a light receiving element are both disposed on the same side of a tissue, and a light reflecting member is required to be disposed on the other side of the tissue.
The traditional indicates abdomen formula oxyhemoglobin saturation sensor is owing to need the homonymy to set up electronic component, the opposite side needs to set up the reflection of light piece, causes thicker size and great weight, and this leads to its adaptation scene narrower, for example, it is difficult to adapt to and sets up in these human tissue positions of nose wing, ear, and its difficult reason of adaptation has: 1. the size is large, which results in the inability to insert into the nasal cavity, 2, the weight is large, the inability to adapt to hanging on the ears, 3, the fingers are thick, the nosewings and the ears are thin, and the stroke of the traditional lever and spring tissue is difficult to adapt. It is therefore desirable to develop a new sensor that can be simultaneously oriented to multiple sites, different tissues, different thicknesses, is lightweight, and can be inserted into the nasal cavity on a single side.
In order to achieve the purpose, patent No. 202120432774.7 discloses a new sensor, which discloses a clamping type oxyhemoglobin saturation monitoring probe, comprising an elastic arc-shaped clamping block, wherein the clamping block is made of elastic hot melt adhesive plastic and has good elasticity, so that the clamping block has proper clamping force, two ends of the clamping block are respectively provided with an inner clamping head and an outer clamping head, the inner clamping head and the outer clamping head are both silica gel sleeves made of transparent silica gel, the upper ends of the inner clamping head and the outer clamping head are both provided with a connecting part, the upper end of the connecting part is provided with an opening, and the connecting part, the inner clamping head, the connecting part and the outer clamping head are all integrally formed; the connecting part is sleeved at the two ends of the clamping block; the inner chuck is internally provided with a red light emitting tube, and the outer chuck is internally provided with a photoelectric detection sensor.
The patent states that: "be provided with ruddiness luminotron in the interior chuck, be provided with the photoelectric detection sensor in the outer chuck, interior chuck and outer chuck are the silica gel cover of transparent silica gel material", "connecting portion and interior chuck, connecting portion and the equal integrated into one piece of outer chuck", "connecting portion cover at the both ends of clamp splice", consequently can find out: in the technical scheme, the clamping blocks are used for driving the connecting parts to displace, and then the connecting parts drive the inner chuck and the outer chuck, so that the force transmission effect is realized in sequence. However, because the inner chuck and the outer chuck are silica gel sleeves, and the connection positions of the inner chuck and the outer chuck and the connection part are in flexible connection, when two ends of the clamping block are only inserted into the connection part, the inner chuck and the outer chuck are excessively outwards turned, and the red light emitting tube and the photoelectric detection sensor are arranged along with the inner chuck and the outer chuck, namely the inner chuck and the outer chuck are excessively outwards turned, and the red light emitting tube and the photoelectric detection sensor are also excessively displaced, which shows that the included angle between the inner chuck and the outer chuck is excessively increased, so that the emitted light cannot be transmitted to the photoelectric detection sensor.
Therefore, the present invention is directed to solving the above problems.

Compared with the prior art, the prior art is connected in order by the clamp splice of "elasticity hot melt adhesive plastics material", "connecting portion", "interior chuck and the outer chuck of transparent silica gel material", because the clamp splice has certain rigidity, and the clamp splice only inserts in "connecting portion", the elasticity of clamp splice is enough to make "connecting portion" and "interior chuck and the outer chuck of transparent silica gel material" take place to turn over between, this can lead to the angle between interior chuck and the outer chuck too big, finally lead to the unable accurate transmission of light to enter into on the response piece of opposite side.

The light receiving element 211 is a light sensing element that receives light passing through human tissue and converts the light into an electrical signal.
As shown in fig. 11, in this embodiment, in order to conveniently calibrate the positions of the light receiving element 211 and the light generating element 221, when in use, the light receiving element 211 and the light generating element 221 may be in a state of being approximately parallel to each other, so that on the basis of the conventional deformation portion, two extending straight sections are added, initially, the two extending straight sections are in an acute oblique state in opposition to each other, when the human tissue 5 is pressed inward from the opening thereof, the two extending straight sections serve as 2 arms, the two extending straight sections themselves do not deform, but the deformation portion is forced to deform to generate elastic potential energy, the two extending straight sections serve as clip arms to clip on both sides of the human tissue 5, and the two extending straight sections displace, i.e., swing around the deformation vertex of the deformation portion, so that the two extending straight sections gradually decrease from an acute angle and finally approach to zero degree, at this time, the two extending straight sections may be considered as being approximately parallel to each other, at this time, the elements assembled inside thereof may also move with each other, i.e., the elements are also in a parallel relationship, so that the two extending straight sections of the invention can ensure that the two extending straight sections directly swing together with the rigidity of the two extending straight sections, i.e., the two extending straight sections can be in a correct relationship. Since the efficiency of the correlation between the elements can be maintained within a range, it is not necessary to be in a parallel state after the wobbling. Therefore, in the present invention, the two extending straight sections provided need to be configured in the following states: as shown in fig. 12, when the deformation portion is in the energy storage state, the extension lines of the two extension straight portions intersect at a point O; as shown in fig. 13, when the deformation portion is expanded to store energy, the extension lines of the extension straight portions are changed to be parallel.

The deformation portion of minor arc can be convenient for preferentially ensure that the extension lines at the two ends of the deformation portion can intersect, and can be opened after human tissue is clamped, so that the extension lines at the two ends of the deformation portion tend to change in parallel.
Then can also set up above-mentioned extension straight section portion on the basis of the deformation portion of arc, V-arrangement, U-shaped, when guaranteeing no energy storage state, require the extension line of extension straight section portion can intersect, when deformation portion opens the energy storage, the extension line of extension straight section portion makes and tends to parallel change.
