Description
Technical Field
The invention relates to the technical field of oxyhemoglobin saturation sensors, in particular to a multi-position oxyhemoglobin saturation sensor.
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 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 oxyhemoglobin saturation sensor is generally a clamp structure composed of a lever and a spring, wherein a light generating element and a light receiving element are both arranged on the same side of a tissue, and a reflective member is required to be arranged on the other side of the tissue.
The traditional finger abdomen type blood oxygen saturation sensor needs to be provided with electronic elements on the same side and a reflector on the other side, so that the sensor is thick in size and heavy, the adaptive scene is narrow, for example, the sensor is difficult to adapt to human tissue parts such as nasal wings and ears, and the reason for the difficult adaptation is as follows: 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; a red light emitting tube is arranged in the inner chuck, and a photoelectric detection sensor is arranged in the outer chuck.
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.

Example 1
As shown in fig. 1 to 13, the present embodiment provides a multi-site blood oxygen saturation sensor, which mainly comprises a deformable elastic member 1, a wire member 2, and an outer cover.
Referring to fig. 1 to 3, 5, 6 and 11:
deformation elastic component 1 includes a deformation portion 13, two extension straight section portions, and two extension straight section portions do respectively: the extension straight section A11 and the extension straight section B12 extend along straight lines from two ends of the deformation part 13 respectively;
the extending straight section A11 is provided with a receiving through hole A111, the extending straight section B12 is provided with a receiving through hole B121, a light receiving element 211 is arranged in the receiving through hole A111, and a light generating element 221 is arranged in the receiving through hole B121.
The light generating element 221 is an integrated element capable of emitting infrared light and red light, that is, two light emitting diodes are arranged in parallel on the integrated element, including a red light emitting diode with a wavelength of about 660nm and an infrared light emitting diode with a wavelength of about 900 nm.
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 the light receiving element 211 and the light generating element 221 are used, 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 a conventional deformation portion, two extending straight sections are added, initially, the two extending straight sections are in an acute oblique state relative 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 clamping arms to be clamped on both sides of the human tissue 5, and the two extending straight sections displace, i.e., swing around a 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 be in a state, at this time, the elements assembled inside thereof may also move with them, i.e., the elements are also in a parallel relationship, therefore, the invention may ensure that the two extending straight sections directly swing at the positions of the two extending straight sections, i.e., the deformation portions, and the two extending straight sections can be in a correct relative to the opposite to the corresponding to the rigid deformation portion, so that the rigidity of the two extending straight sections can be directly guarantee the corresponding to the deformation portion. 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 two extending straight sections which are directly and rigidly connected with the deformation part are created, the accommodating through holes are created in the two extending straight sections, and the element is directly assembled in the through holes, so that the element can swing along with the swing of the two ends of the deformation part, and the bijection effectiveness of the element is finally ensured.
In order to ensure that the component is held within the through hole, a through hole that is the same size as the component or slightly smaller than the component can be created to achieve an interference fit. In practical engineering, manufacturing errors of the through holes are difficult to guarantee, and manufacturing errors of elements exist, so that the embodiment of directly clamping the elements into the through holes is difficult to realize, and although the embodiment is difficult to realize, the protection scope of the invention does not exclude the embodiment.
In order to fix an element in a through hole, the invention provides a technical concept of bonding a step through hole, which specifically comprises the following steps: the accommodating through hole A111 or/and the accommodating through hole B121 is/are a step through hole; a step surface A1111 for blocking and adhering to the front edge of the light receiving element 211 is formed in the accommodating through hole A111 and/or a step surface B1211 for blocking and adhering to the front edge of the light generating element 221 is formed in the accommodating through hole B121;
the light receiving element 211 is fitted into the contents through hole a111 with its front surface facing the step surface a1111, and the light generating element 221 is fitted into the contents through hole B121 with its front surface facing the step surface B1211.
The assembly is preferably an adhesive assembly.
Preferably, the shape of the deformation part is one of an arc shape, a V shape and a U shape, and the deformation part is preferably a minor arc. The deformation part of the minor arc can be convenient for preferentially ensuring that the extension lines at the two ends of the deformation part can intersect, and can be opened after human tissues are clamped, so that the extension lines at the two ends of the deformation part tend to change in parallel.
The extension straight section part can be arranged on the basis of the deformation parts of the arc shape, the V shape and the U shape, when the energy storage-free state is ensured, the extension lines of the extension straight section part are required to be intersected, and when the deformation parts are opened for energy storage, the extension lines of the extension straight section part tend to change in a parallel mode.
Simultaneously, can also set up a hole 131 in deformation portion, its effect is to reduce deformation elastic potential energy, reduces the dynamics of oppressing to human tissue 5, can also promote simultaneously and alleviate whole weight, improves user experience.
