Description

Technical Field

[0001] This invention relates to the field of medical testing, and more particularly to an auxiliary device for medical testing. Background Technology

[0002] In the diagnosis and treatment of sleep-disordered breathing in children, sleep apnea testing is necessary, primarily for screening and diagnosing conditions such as obstructive sleep apnea. If these conditions are not addressed promptly, they can affect a child's growth and development, cognitive function, and cardiovascular health. Traditional testing devices often employ dual airflow sensors, inserted into each of the child's nostrils, with a horizontal tube connecting the two sensors for fixation and connection. However, because children's nostrils are generally smaller, this horizontal tube occupies limited space within the nasal cavity, physically obstructing and interfering with normal airflow. This can distort the detected airflow signal, affecting data accuracy and increasing discomfort for the child. To eliminate interference from the horizontal tube, existing technology has improved the nasal clip-type breathing detection device. It uses a nasal clip to clamp directly onto the child's nose bridge, replacing the horizontal tube connection below the nostrils. Although this method avoids direct obstruction caused by the horizontal tube below the nostrils, the skin at the root of the child's nose is delicate and the bones are not yet fully hardened. Prolonged or excessively tight clamping can easily cause local skin redness, pain, or even damage. More importantly, when the nasal clip applies pressure to clamp the root of the nose, it may compress the soft tissue of the nose, causing the internal breathing passage of the nose to collapse and constrict, thereby changing the natural state of airflow and affecting the child's breathing patency and the accuracy of the detection. Summary of the Invention

[0003] In order to overcome the shortcomings of existing medical testing devices for children's sleep-disordered breathing, which affect the accuracy of the test by interfering with the patency of children's breathing when testing sleep-disordered breathing in the nasal area, the present invention provides an auxiliary device for medical testing.

[0004] The technical implementation scheme of the present invention is as follows: an auxiliary device for medical testing, comprising a headrest, an anti-loosening band, a fixing band, an elastic band, a connector, a right fixing seat, a left fixing seat, an inner clamping block, and an airflow detection sensor; an anti-loosening band is fixedly attached to the upper side of the headrest; two fixing bands are fixedly attached to the headrest; the fixing bands are provided with a plurality of buckle block structures; two elastic bands are slidably connected to the headrest; the elastic bands are provided with a plurality of buckle hole structures corresponding to the buckle blocks; a connector is fixedly attached to the elastic band; a right fixing seat is fixedly attached to the right connector; a left fixing seat is fixedly attached to the left connector; the left fixing seat connects to the right fixing seat; a hollow channel structure is provided in the middle between the left fixing seat and the right fixing seat; an inner clamping block is fixedly attached to the connector; an airflow detection sensor is installed on each of the two inner clamping blocks facing each other.

[0005] As a preferred embodiment of the present invention, two back strips are fixedly connected to the back side of the headrest; two left and right limiting pillows are slidably connected between the two back strips.

[0006] As a preferred embodiment of the present invention, an outer clamping block is fixedly attached to the connector head, and the outer clamping block is located on the same side as the inner clamping block away from the airflow detection sensor.

[0007] As a preferred embodiment of the present invention, a blood oxygen detection transmitter is installed on the opposite sides of the two inner clamping blocks; and a blood oxygen detection receiver aligned with the blood oxygen detection transmitter on the opposite sides of the two outer clamping blocks is installed on the opposite sides of the two outer clamping blocks.

[0008] As a preferred embodiment of the present invention, the right fixed seat is slidably connected to the left fixed seat; an adjusting screw for adjusting the moving distance of the right fixed seat is installed on the left fixed seat.

[0009] As a preferred embodiment of the present invention, a thin-film sensor is installed on each of the two inner clamping blocks on opposite sides.

[0010] As a preferred embodiment of the present invention, a warning light electrically connected to the corresponding thin-film sensor on the same side is installed on the right fixed base; a warning light electrically connected to the corresponding thin-film sensor on the same side is also installed on the left fixed base.

[0011] As a preferred embodiment of the present invention, the head pad uses a skin-friendly silicone pad material.

[0012] As a preferred embodiment of the present invention, the head pad is provided with a plurality of anti-slip embossed structures.

[0013] As a preferred technical solution of the present invention, the head pad is provided with a plurality of breathable groove structures.

[0014] The beneficial effects of this invention are as follows: This invention provides an auxiliary device for medical testing. Two connectors, each fixing two inner clips, are connected to the headrest via a fixing strap and an elastic band. A hollow channel is formed in the right and left fixing seats between the two connectors to prevent interference with the smooth flow of respiratory airflow. By pulling the inner clips with the elastic band, a slight outward expansion and compression force is applied to the inner side of the child's nostrils, allowing the airflow detection sensor on the inner clips to be easily fixed inside the child's nostrils. Simultaneously, the child's nostrils remain expanded, ensuring normal airflow through the nasal passages. Furthermore, an adjustable screw, in conjunction with a thin-film sensor, constitutes an active safety protection system, which can prevent discomfort or soft tissue damage to the child's nostrils. The device issues warnings before damage occurs, enhancing the product's medical safety level and user trust. Furthermore, a pulse oximeter transmitter and receiver are integrated between the inner and outer clips, replacing fingertip pulse oximeters for pulse oximetry. This high integration of multiple detection components prevents them from becoming loose during sleep due to children's movement. It not only improves the accuracy of existing medical detection devices for children's sleep apnea when detecting breathing through the nasal area, which can interfere with the child's breathing, but also maximizes the comfort of the headrest. This is a typical example of human-centered design in wearable detection devices for children. Attached Figure Description

Detailed Implementation

[0017] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Example 1: An auxiliary device for medical testing in this example, such as... Figures 1-5 As shown, it includes a headrest 1, an anti-loosening strap 111, a fixing strap 11, an elastic band 12, a connector 13, a right fixing seat 14, a left fixing seat 15, a back strip 16, a limiting pillow 17, an inner clamping block 21, and an airflow detection sensor 3; the anti-loosening strap 111 is fixed to the upper side of the headrest 1, and the left and right ends of the anti-loosening strap 111 are fixed to the left and right sides of the headrest 1, respectively; two fixing straps 11 are fixed to the headrest 1; each of the two fixing straps 11 is provided with several buckle blocks 11. 01 Structure; Two elastic bands 12 are slidably connected to the head pad 1, and the elastic bands 12 are aligned with the fixing band 11 on the same side; each of the two elastic bands 12 has several buckle holes 1201, and the buckle holes 1201 are adapted to the buckle blocks 1101 on the fixing band 11 on the same side. By adjusting the corresponding position of the buckle blocks 1101 of the fixing band 11 and the buckle holes 1201 of the elastic band 12 on the same side, the buckle blocks 1101 of the fixing band 11 can be fastened. The elastic bands 12 are fastened in the corresponding buckle holes 1201, which can adjust the extension length of the two elastic bands 12 on the front side of the head pad 1 and fix the elastic bands 12 on the fixing strap 11 to adapt to the head circumference of different children. Each of the two elastic bands 12 has a connector 13 fixed to its opposite side. A right fixing seat 14 is fixed to the right connector 13. A left fixing seat 15 is fixed to the left connector 13. The left fixing seat 15 is connected to the right fixing seat 14. A hollow channel 1501 structure is opened in the middle between the left fixing seat 15 and the right fixing seat 14. Two back strips 16 are fixed to the back side of the head pad 1. A limiting pillow 17 is slidably connected between the left sides of the two back strips 16. A limiting pillow 17 is also slidably connected between the right sides of the two back strips 16. An inner clamping block 21 is fixed to each of the two connectors 13. An airflow detection sensor 3 is installed on the opposite side of each of the two inner clamping blocks 21. The airflow detection sensor 3 is powered by an external circuit.

[0019] like Figures 3-5 As shown, each of the two connectors 13 has an outer clamp 22 fixedly attached. The outer clamp 22 is located on the side of the inner clamp 21 away from the airflow detection sensor 3, and the two inner clamps 21 are located between the two outer clamps 22. A blood oxygen detection transmitter 41 is installed on the opposite side of each of the two inner clamps 21. A blood oxygen detection receiver 42 is installed on the opposite side of each of the two outer clamps 22, and the blood oxygen detection receiver 42 is aligned with the blood oxygen detection transmitter 41 on the same side. Both the blood oxygen detection transmitter 41 and the blood oxygen detection receiver 42 are powered by an external circuit.

[0020] In use, the tester first places the head pad 1 firmly against the back of the child's head, then places the anti-loosening strap 111 forward over the child's forehead, and places the inner clips 21 on the two connectors 13 firmly against the inside of the child's two nostrils. The two airflow detection sensors 3 are then placed into the two nostrils. At this time, the outer clips 22 on the two connectors 13 are firmly against the outside of the child's two nostrils, forming a state where the inner clips 21 and the corresponding outer clips 22 are clamped on the corresponding nostrils. Then, the elastic band 12 is slightly stretched and fastened to the corresponding fixing band 11. At this time, the stretched elastic band 12 pulls the inner clips 21 under the action of the reverse elastic force, applying a slight expansion and squeezing force to the inside of the child's nostrils, thereby opening the child's nostrils and keeping them in an expanded state, thus ensuring normal airflow in the child's nasal passages.

[0021] Afterwards, the testing personnel guided the child to lie on the testing bed and waited for the child to fall asleep. The testing personnel then monitored the child's sleep breathing status through the airflow detection sensors 3 in the child's two nostrils. During this period, the hollow channel 1501 between the left fixation seat 15 and the right fixation seat 14 ensured that the child's breathing airflow could flow smoothly. At the same time, the blood oxygen detection transmitter 41 and blood oxygen detection receiver 42 on the inner clamp 21 and the outer clamp 22 were respectively attached to the inner and outer sides of the child's nose. The blood oxygen detection transmitter 41 and blood oxygen detection receiver 42 were used to detect the blood oxygen saturation of the child's nose area, replacing the use of a fingertip blood oxygen detector. This achieved a high degree of integration of multiple detection components and prevented the various detection components from becoming loose due to the child's body shaking during sleep, ensuring that the sleep breathing test and blood oxygen saturation test of the child could be carried out normally.

[0022] When the child lies flat on the testing bed, the two limiting pillows 17 on the back of the headrest 1 are respectively positioned on the left and right sides of the child's head. The limiting pillows 17 provide lateral support to the child's head, preventing the child from turning over or shifting their head during sleep, thus maintaining the child's supine position for sleep apnea testing. When it is necessary to conduct sleep apnea testing in a side-lying position, the tester guides the child to lie on their side on the testing bed and moves the limiting pillows 17 on the back strip 16 so that the limiting pillows 17 are aligned with the middle area of ​​the back of the child's head. When the child's head is in a side-lying position on the testing bed, the limiting pillows 17 provide lateral support to the middle area of ​​the back of the child's head, preventing the child from turning over and returning to a supine position during sleep, thus maintaining the child's side-lying position for sleep apnea testing.

[0023] Example 2, based on Example 1, such as Figures 1-7As shown, in this embodiment of an auxiliary device for medical testing, a right fixed base 14 is slidably connected to a left fixed base 15; an adjusting screw 18 is rotatably connected to the left fixed base 15; the threaded structure of the adjusting screw 18 is screwed onto the right fixed base 14; a thin-film sensor 5 is installed on each of the two inner clamping blocks 21 on opposite sides, and the thin-film sensor 5 is powered by an external circuit; a warning light 6 is installed on the right fixed base 14; a warning light 6 is also installed on the left fixed base 15; the two warning lights 6 are electrically connected to the opposite side of the same circuit system. The corresponding thin-film sensor 5; when the head pad 1 is fixed to the back of the child's head according to the above steps, and the two elastic bands 12 are stretched to clamp the two inner clips 21 on the inner sides of the child's two nostrils respectively, the stretched elastic bands 12 pull the inner clips 21 under the action of the reverse elastic force, which causes the thin-film sensor 5 to apply an outward expansion and squeezing force to the inner side of the child's nostrils. At this time, the magnitude of the expansion and squeezing force applied by the inner clips 21 to the inner side of the child's nostrils will be detected by the thin-film sensor 5 in real time. When the thin-film sensor 5 detects the inner clips 21 applying an outward expansion and squeezing force to the inner side of the child's nostrils, the sensor will detect the expansion and squeezing force. When the applied expansion pressure exceeds the specified range, the warning light 6 on the same side will flash to alert the testing personnel that the current inner clamp 21 is applying too much expansion pressure to the child's nasal ala, which could easily damage the soft tissue of the child's nasal ala. At this time, the testing personnel will rotate the adjusting screw 18, which will move the right fixing seat 14 away from the left fixing seat 15, increasing the distance between the two inner clamps 21 on the right fixing seat 14 and the left fixing seat 15. This will reduce the length of the elastic band 12 being stretched and the magnitude of the generated reverse elastic force, thereby reducing the expansion pressure applied by the elastic band 12 to the inner clamp 21 on the child's nasal ala. This constitutes an active safety protection system that can issue a warning before causing discomfort or soft tissue damage to the child's nasal ala. This is especially important for children with delicate skin and mucous membranes, improving the medical safety level and user trust of the product, protecting children from physical pressure injuries to the greatest extent, and significantly improving the safety, comfort, and reliability of the entire testing process.

[0024] Example 3, based on Example 1, such as Figures 1-5As shown, an auxiliary device for medical testing includes a headrest 1 made of skin-friendly silicone material. The headrest 1 has several anti-slip raised textures 101. After being fixed to the back of a child's head, the headrest 1 adheres tightly to the back of the child's head through the anti-slip raised textures 101, preventing frequent head movement during sleep and thus reducing relative displacement between the headrest 1 and the child's head, enhancing the secure fixation of the headrest 1 on the child's head. The headrest 1 also has several ventilation grooves 102. When the headrest 1 is in close contact with the back of the child's head, the ventilation grooves 102 create several airflow channels, enhancing breathability and helping to expel heat and moisture from the head, keeping it warm. Keeping the contact area dry improves sleep comfort and reduces skin problems caused by stuffiness. Since the skin-friendly silicone pad material used in the head pad 1 has excellent flexibility, the ventilation grooves 102 make the material used in the head pad 1 more flexible in certain areas, improving the fit of the head pad 1 to different head shapes. This allows it to more flexibly adapt to the curvature of the back of the child's head. Based on the friction fixation provided by the anti-slip ridges 101, the better fit further reduces relative displacement. Ultimately, while ensuring a firm fixation, it maximizes wearing comfort, breathability, and adaptability, which is a typical example of humanized design in children's wearable detection devices.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
