Description
Technical Field
The invention relates to the technical field of oximeter, in particular to a portable blood oxygen analysis device for mobile health physical examination.
Background
The meaning of monitoring blood oxygen in outdoor scenes (non-medical professional scenes) is very important, for example, in outdoor activities, especially under conditions of high altitude, high temperature, high humidity, etc., the human body is at risk of insufficient oxygen supply. The following are the meanings of monitoring blood oxygen in some specific outdoor scenarios, such as: high altitude activities such as mountain climbing and hiking.
In high altitude areas, the air pressure is lower, the oxygen concentration is correspondingly lower, and the oxygen deficiency of the body is easy to cause. Therefore, when the high-altitude activity is carried out, monitoring the blood oxygen saturation can help people to know the adaptation condition of the body to the altitude environment, judge whether the body is suitable for the high-altitude environment or not, and avoid the problems of altitude reaction and the like.
When long-term outdoor activities such as hiking, camping, etc. are performed, the human body is exposed to the natural environment for a long time, and may be affected by insufficient oxygen supply. At the moment, monitoring the blood oxygen saturation can help people to find the condition of the oxygen deficiency of the body in time, and take measures in time to avoid unnecessary injury to the body.
Under high temperature, high humidity and other environments, metabolism of the human body can be accelerated, and more oxygen is needed to maintain normal physiological functions. At the moment, monitoring the blood oxygen saturation can help people to find the condition of hypoxia of the body in time, and avoid uncomfortable symptoms such as fatigue, dizziness and the like of the body.
The blood oxygen concentration test of medical profession is not suitable for the above outdoor environment, and mainly comprises the following performances: (1) the clamping body has poor cladding property on the finger belly, and as a general commodity with a limited model, the clamping device usually aims at adapting to the finger size of most users, and the difference of the clamping cladding property of different sizes under the clamping structure is large. Specifically, in order to enable a thinner finger to have a better clamping effect (key for ensuring a detection effect), a finger belly reserved space inside the clamping body is usually set smaller, and a problem caused by such a design is that when a user with a larger finger belly size measures, the opening front end of the clamping body is poor in closing effect, and the scissor lever structure of the whole clamping body is in an open posture. In the existing products, flexible structures such as silica gel and the like are usually used at the clamping positions of the finger abdomen, so that the purpose is to improve the hand feeling of the product contacting fingers on one hand, and to provide certain adaptability to the finger abdomen with different sizes on the other hand, but the scheme has extremely limited application range.
In addition, when the structure is used for the abdomen of a large-size finger, the whole clamping and fixing effect of the clamping main body is poor (because the front end is in an open state), and the whole equipment is easy to fall off in the measuring process.
(2) No environmental infrared shielding effect. When outdoor/outdoor measurement is carried out, the uncertainty of the environmental infrared signal is strong, and the environmental infrared signal directly acts on the sensor and is superposed into a measurement result.
When the sensor is used for detecting different main bodies (users), the relative positions of the sensor and the detection part are inconsistent, and the detection result has deviation. In the different postures of the problem (1), the relative angles of the infrared transmitting tube and the detecting tube (receiving tube) of the sensor and the finger belly are usually different from the postures of the product in verification (calibration). If the influence of this attitude difference is not taken into account in the data processing (the usual algorithm is not correcting the deviation of the detected angle either), the measurement results will deviate.
In order to solve the above problems, a portable blood oxygen analyzer for mobile health examination has been proposed.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The meaning of monitoring blood oxygen in outdoor scenes (non-medical professional scenes) is very important, for example, in outdoor activities, especially under conditions of high altitude, high temperature, high humidity, etc., the human body is at risk of insufficient oxygen supply. The following are the meanings of monitoring blood oxygen in some specific outdoor scenarios, such as: high altitude activities such as mountain climbing and hiking.
In high altitude areas, the air pressure is lower, the oxygen concentration is correspondingly lower, and the oxygen deficiency of the body is easy to cause. Therefore, when the high-altitude activity is carried out, monitoring the blood oxygen saturation can help people to know the adaptation condition of the body to the altitude environment, judge whether the body is suitable for the high-altitude environment or not, and avoid the problems of altitude reaction and the like.
When long-term outdoor activities such as hiking, camping, etc. are performed, the human body is exposed to the natural environment for a long time, and may be affected by insufficient oxygen supply. At the moment, monitoring the blood oxygen saturation can help people to find the condition of the oxygen deficiency of the body in time, and take measures in time to avoid unnecessary injury to the body.
Under high temperature, high humidity and other environments, metabolism of the human body can be accelerated, and more oxygen is needed to maintain normal physiological functions. At the moment, monitoring the blood oxygen saturation can help people to find the condition of hypoxia of the body in time, and avoid uncomfortable symptoms such as fatigue, dizziness and the like of the body.
Referring to fig. 1 to 11, a portable blood oxygen analyzer for mobile health examination, comprising: the blood oxygen analyzer comprises an oxygen analyzer body 1, wherein a sensor is arranged in the oxygen analyzer body 1 and is used for detecting finger pressure data; the oximeter body 1 is provided with an infrared shielding unit, and the infrared shielding unit can separate infrared radiation in the environment from the sensor and prevent the external infrared radiation from interfering with the detection data of the sensor.
Specifically, in an outdoor environment, there are many infrared radiations interfering with the accuracy of the detection data of the oximeter body 1, and the present invention employs an infrared shielding unit to separate the sensors so that the sensors directly act on the finger to be detected. The infrared shielding unit can be a coating for reflecting infrared radiation, or can be a clamping body made of an infrared radiation absorbing material, and the finger to be detected is included by the clamping body to realize isolation with the outside.
In this embodiment, the oximeter body 1 includes: the finger-touch device comprises two clamping plates 2 which are connected in a hinged mode, wherein at least one clamping plate 2 is provided with an infrared shielding unit, the infrared shielding unit is a bag cavity 3 provided with a coating layer or a medium layer made of infrared reflecting materials, and the bag cavity 3 can completely wrap fingers.
Specifically, the capsule cavity 3 is an elastic structure body with a cavity in the epidermis, when a finger to be detected is placed on the capsule cavity 3, extrusion deformation can be generated, the finger to be detected is wrapped in the elastic structure body, and the coating of the infrared reflecting material can isolate the interference between the detection area and external radiation; in addition, the cavity can be filled with a liquid medium or a gas medium with air pressure, wherein the medium can absorb infrared radiation, so that a small amount of infrared radiation passing through the surface of the capsule cavity 3 is absorbed therein, and the influence of external infrared radiation is further weakened.
In this embodiment, the capsule cavity 3 is provided with a connection surface 304, the connection surface 304 is fixedly connected with the inner wall of the corresponding clamping plate 2, the opposite surface of the connection surface 304 is a first pressure release channel 301, the first pressure release channel 301 is an extrusion surface where the capsule cavity 3 is in direct contact with a finger, and the sensor is arranged in the first pressure release channel 301, and when in use, the sensor is completely attached to the finger along with the first pressure release channel 301; two sides of the capsule cavity 3 are provided with second pressure release channels 302, and the thickness of the second pressure release channels 302 is larger than that of the first pressure release channels 301.
The first pressure release channel 301 has the thinnest skin thickness, and is deformed by extrusion at the first time when contacting with the finger to be measured, so as to wrap the whole finger surface therein. Specifically, in this embodiment, two capsules 3 are respectively installed on the inner walls of the upper and lower clamping plates 2. When the two clamping plates 2 are locked, the generated extrusion force is further increased, so that the second pressure release channels 302 with the skin thickness larger than that of the first pressure release channels 301 are expanded outwards, and the second pressure release channels 302 of the upper and lower two bag cavities 3 are in mutual extrusion contact on the same side, so that the fingers to be tested are thoroughly wrapped.
In this embodiment, a liquid medium or a gas medium with a certain pressure is disposed in the capsule cavity 3.
In this embodiment, the oximeter body 1 is provided with a locking mechanism 4, and the locking mechanism 4 includes:
the fixed magnetic blocks 401, wherein the fixed magnetic blocks 401 fixedly connected with one clamping plate 2 are arranged on two sides of the clamping plate;
the movable magnetic blocks 402, and the second pressure release channels 302 at two sides of the capsule cavity 3 are respectively and fixedly connected with the movable magnetic blocks 402;
when the first pressure release channel 301 is deformed by extrusion, the second pressure release channel 302 expands to two sides, driving the movable magnetic block 402 and the fixed magnetic block 401 to be adsorbed and locked.
When the device is not used, the fixed magnetic block 401 is not attracted with the movable magnetic block 402 because the capsule cavity 3 is in an expanded state, so that the magnetism is weaker, and the whole device is easier to open. However, when the finger to be tested is clamped, the movable magnetic block 402 is pushed by the capsule cavity 3 to move to the fixed magnetic block 401 to be attracted with the fixed magnetic block, and the magnetism is rapidly enhanced, so that the clamping plate 2 has a stronger closing effect. The structure realizes the effect of self-adaptive firm closing, compared with the effect of the traditional spring, the spring with larger elasticity is avoided to influence the use and assembly, and the clamping life is weakened due to the fatigue of the spring material. The opening in the unused state becomes extremely easy while providing a large closing force.

Specifically, the stay bar 6 is a hard stay bar 6 fixedly connected with the capsule cavity 3, and nylon bars, hard plastics and the like can be used. The movable magnetic block 402 is driven by the stay bar 6, so that the effect of pushing the movable magnetic block 402 to be adsorbed with the fixed magnetic block 401 can be achieved by reducing the deformation size of the second pressure release channel 302.
In this embodiment, the movable magnetic block 402 is provided with a guiding mechanism, and the guiding mechanism includes:

the movable magnetic block 402 is provided with a guide groove corresponding to the guide rail 5 and is in sliding connection with the guide rail 5.
Wherein, guide rail 5 is disposed on clamping plate 2 opposite to fixed magnetic block 401, so that when movable magnetic block 402 slidingly connected with guide rail 5 is adsorbed on fixed magnetic block 401, two clamping plates 2 are in locking state.
In this embodiment, a third pressure release channel 303 is disposed on the bladder cavity 3, the third pressure release channel 303 is located at two sides of the bladder cavity 3, specifically located between the connection surface 304 and the second pressure release channel 302, and has a thickness greater than that of the second pressure release channel 302, and an adjusting mechanism is disposed on the clamping plate 2 corresponding to the third pressure release channel 303, and the adjusting mechanism acts on the third pressure release channel 303 to adjust the pressure in the bladder cavity 3.
Wherein the clamping plate 2 of the oximeter body 1 provides a large internal space, which is filled by the adaptive bladder cavity 3. And according to the self-adaptive deformation of the capsule cavity 3, the complete coating of the finger and the standardization of the detection position/detection direction of the sensor are realized. An adjusting mechanism is provided on the oximeter body 1, and acts on the third pressure release channel 303 of the capsule 3 to press the third pressure release channel 303. The internal pressure of the capsule cavity 3 can be properly improved after the self-adaptive posture of the capsule cavity 3 is adjusted, the coating effect of the capsule cavity 3 on the detection finger is further improved, the shielding effect of the capsule cavity 3 on the ambient infrared radiation after the coating is formed, and the ten-thousand-bridge coating of fingers with different sizes can be met through the adjusting mechanism.
