Description

Technical Field

[0001] The present invention provides a pulse oximetry monitor for monitoring children, and particularly relates to the technical field of medical devices. Background Art

[0002] Pediatric patients are physically fragile, and their condition often changes rapidly. A pulse oximeter monitor can continuously and in real time monitor a child's blood oxygen saturation and pulse. By monitoring blood oxygen saturation, it's possible to promptly detect hypoxia in children.

[0003] Currently, a utility model with authorization publication number CN220385057U discloses a blood oxygen monitoring device for premature infants. This device uses a drive motor to drive a gear to rotate forward and backward, which in turn drives two blood oxygen probes to automatically switch between use. This prevents excessive heat accumulation after prolonged use of one probe, which could cause burns to the premature infant's skin. Furthermore, a utility model with authorization publication number CN215305816U discloses a wristband for monitoring heart rate and blood oxygen levels in infants. During use, a staff member places the device on the user's wrist or ankle, then passes one end of the fixing strap around the wrist or ankle, passes one end of the fixing strap through the notch, and exits through the inner limiting hole. The fixing strap is then passed through the outer limiting hole to the notch, thereby connecting the fixing strap to the positioning plate. This allows the device to be worn on the user, and the provision of an inflatable bag increases wearing comfort.

[0004] Both of the aforementioned pediatric blood oxygen monitoring devices use a single strap to secure the entire device to the child's limb. This single strapping method is unstable and prone to falling off during use, making it impossible to ensure the stability of the monitored blood oxygen saturation data. Furthermore, neither of these devices automatically adjusts the monitoring probe's position. If the probe remains in the same position for extended periods, it can cause discomfort to the child and can also lead to excessive heat accumulation in one location, potentially causing burns.

[0005] Therefore, the present invention proposes a pulse oximetry monitor for pediatric monitoring to remedy and improve the deficiencies of the prior art. Summary of the Invention

[0014] Preferably, the combined pipe and the air outlet nozzle are both made of hard PVC material, and the air outlet nozzle is horizontally located on one side below the monitoring probe and the semicircular cabin.

[0016] Beneficial effects of the present invention: This pulse oximetry monitor for pediatric monitoring uses a timing controller to control the timing of the start and stop of a small motor, driving the monitoring probe to automatically change its monitoring position on the sole of the child's foot. This avoids the monitoring probe from monitoring at the same position on the child's foot for a long time, which may cause local pressure and discomfort, thereby improving the child's comfort during monitoring. At the same time, the monitoring probe does not come into contact with the child's foot during the position change process, reducing the risk of friction damage to the child's foot caused by moving the monitoring probe. The automatic change of the monitoring probe's monitoring position allows monitoring at different locations on the child's foot, improving the comprehensiveness of the blood oxygen saturation monitoring data. The monitor can be conveniently worn on the child's foot through the cooperation of the provided foot cavity plate, support, positioning ring and other components. The monitor and the child's foot are restrained at three locations, effectively ensuring the stability of the monitor during use, thereby preventing the monitoring probe from easily shifting against the child's foot and ensuring the effectiveness of the monitoring probe in monitoring blood oxygen saturation. By cooperating with the adjustment screw and the sleeve block and other components, medical staff can freely adjust the distance between the support and the positioning ring to better suit children with different foot lengths and sizes, thereby improving the applicability of the monitor. The monitoring probe is clamped and fixed by two semicircular cabins, two sliding sleeves, a slotted plate and a spring. When the monitoring probe needs to be replaced, the two semicircular cabins are separated towards each other and the monitoring probe can be moved upward and taken out, thereby improving the convenience of replacing and installing the monitoring probe of the monitor. Through the cooperation of the fan blades and the air outlet nozzle and other components, when the monitoring probe changes its monitoring position, the heat around the monitoring probe and the semicircular cabin is also taken away, avoiding excessive heat accumulation around the two and causing burns to the soles of the children's feet, thereby improving the safety of the monitoring operation of the monitoring probe. At the same time, because the fan blades will only operate synchronously when the monitoring probe changes its position regularly, it also avoids the situation where the soles of the children's feet become too cold due to long-term continuous heat dissipation, reducing the discomfort caused to the children. The cotton strip can be used to absorb the sweat on the surface of the monitoring probe during the process of switching the position of the monitoring probe, thereby reducing the impact of sweat on the blood oxygen saturation monitored by the monitoring probe, thereby ensuring the effectiveness of the monitoring probe's monitoring; By utilizing the cooperation of torsion spring pawls, storage trays and other components, the used tampons can be automatically rolled up and the unused tampons can be automatically released during the process of changing the position of the monitoring probe, thereby ensuring the effectiveness and sustainability of the subsequent sweat absorption by the tampons.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Example 1: Figures 1 to 2 As shown, a pulse oximetry monitor for pediatric monitoring includes a foot-attaching cavity plate 1, the interior of which is configured as a cavity. Heat dissipation holes 102 are evenly distributed around the perimeter of the foot-attaching cavity plate 1. A through-hole 101 is provided on the foot-attaching cavity plate 1. A support 11 is slidably connected to the upper surface of the foot-attaching cavity plate 1 on the side away from the through-hole 101. The support 11 is arc-shaped, and a cotton layer is provided on the outer surface of the support 11 to better fit the child's heel and enhance the comfort of the support 11 and the child's heel. A strap 12 is provided on the side of the support 11 near the through-hole 101. One end of the strap 12 is fixedly connected to the outer surface of the support 11, and the other end of the strap 12 is provided with a Velcro tape that can be bonded to the outer surface of the support 11. An adjustment screw 13 is rotatably connected to the bottom surface of the inner cavity of the foot-adhering cavity plate 1. The end of the adjustment screw 13, which is closest to the support 11, extends to the outside of the foot-adhering cavity plate 1. Two sleeves 14 are symmetrically threaded onto the adjustment screw 13, and the adjustment screw 13 is provided with bidirectional threads. A positioning ring 15 is fixedly connected to the top surface of the sleeve 14 on the side away from the support 11. Specifically, the positioning ring 15 consists of an upper circular ring and an L-shaped plate fixedly connected to the circular ring. The end of the L-shaped plate, which is away from the circular ring, is fixedly connected to the top surface of the sleeve 14 on the side away from the support 11. The L-shaped plate in the positioning ring 15 is slidably connected to the foot cavity plate 1. A connecting rod on the top surface of another sleeve 14 extends upward from the foot cavity plate 1, and one end of the connecting rod is fixedly connected to the bottom surface of the support 11. Specifically, the foot cavity plate 1 and the connecting rod in the support 11, and the L-shaped plate in the positioning ring 15 are provided with strip grooves at positions corresponding to the positions, so that the support 11 and the positioning ring 15 can be horizontally displaced toward or away from each other along the track of the strip grooves. A monitor body 16 and a timing controller 17 are respectively installed on the peripheral wall of the foot cavity plate 1 near the positioning ring 15. A monitoring probe 18 is provided on the side of the through-port 101 near the monitor body 16. The monitoring probe 18 is electrically connected to the monitor body 16. The blood oxygen saturation is monitored after the monitoring probe 18 is in contact with the skin of the child's foot, and the data is displayed in real time through the monitor body 16. During use, a medical professional aligns the sole of the child's foot with the upper surface of the foot-attaching cavity plate 1, and then rotates the adjustment screw 13 forward and backward according to the length of the child's foot. The forward and reverse rotation of the adjustment screw 13 drives the two sleeves 14 to move horizontally toward or away from each other, thereby driving the support 11 and the positioning ring 15 to move horizontally synchronously along the track of the strip groove on the foot-attaching cavity plate 1, thereby adjusting the distance between the support 11 and the positioning ring 15. Ultimately, the positioning ring 15 needs to be placed on the big toe of the child's foot, and the support 11 can be attached to the heel of the child's foot. Then, the strap 12 is passed around the top of the child's ankle, and the end with the Velcro is attached to the outer surface of the support 11. This completes the restraint and fixation of the foot-attaching cavity plate 1, the support 11, the positioning ring 15, and the child's foot. As the sole of the child's foot contacts the upper surface of the foot-mounted cavity plate 1, the upper surface of the monitoring probe 18 comes into contact with the skin of the child's foot. This allows the monitoring probe 18 to monitor the child's blood oxygen saturation, and the monitor body 16 then displays the blood oxygen saturation data in real time. Therefore, through the coordination of the foot-mounted cavity plate 1, the support 11, and the positioning ring 15, the monitor can be conveniently worn on the child's foot. The three positions constrain the monitor to the child's foot, effectively ensuring the monitor's stability during use, preventing easy displacement of the monitoring probe 18 from the child's foot and thus ensuring the effectiveness of the monitoring probe 18 in monitoring blood oxygen saturation. Furthermore, through the coordination of the adjustment screw 13 and the sleeve 14, medical personnel can freely adjust the spacing between the support 11 and the positioning ring 15, thereby better accommodating children with different foot lengths and improving the monitor's usability.

[0021] Furthermore, if Figures 1 to 7 、 Figure 9As shown, the above-mentioned pulse oximetry monitor for pediatric monitoring also includes an active shifting mechanism arranged at the position of the through-hole 101 corresponding to the foot cavity plate 1, and the active shifting mechanism includes an inner plate 21 fixedly connected to the bottom surface of the inner cavity of the foot cavity plate 1, a small motor 22 is fixedly installed on the upper surface of the inner plate 21, a reciprocating screw rod 23 is rotatably connected to the upper surface of the inner plate 21, the output shaft end of the small motor 22 is fixedly connected to the reciprocating screw rod 23, and a displacement plate 24 is threadedly connected to the reciprocating screw rod 23, the bottom of the displacement plate 24 is slidably connected to the upper surface of the inner plate 21, and the displacement plate 24 is initially located on the side close to the small motor 22, and a limit groove for horizontal displacement of the displacement plate 24 is provided at the position corresponding to the bottom of the displacement plate 24 on the upper surface of the inner plate 21, and the two ends of the displacement plate 24 away from the reciprocating screw rod 23 are respectively fixedly connected with slotted plates 25, and the two slotted plates 25 are respectively installed inside the side close to each other. There is a sliding sleeve 26, and a spring 1 27 is fixedly connected between the sliding sleeve 26 and the groove surface of the slotted plate 25 away from the sliding sleeve 26. A matching block 29 is slidably connected to the top of the sliding sleeve 26, and a spring 28 is fixedly connected between the bottom surface of the matching block 29 and the inner bottom surface of the sliding sleeve 26. The end of the matching block 29 away from the spring 28 is fixedly connected to a semicircular cabin 210. There are two semicircular cabins 210, and the two semicircular cabins 210 form a complete disc shape. The above-mentioned monitoring probe 18 is placed horizontally in the two semicircular cabins 210, and the monitoring probe 18 is clamped and fixed by the two semicircular cabins 210 and the two sliding sleeves 26, the slotted plate 25 and the spring 1 27. When the monitoring probe 18 needs to be replaced, the two semicircular cabins 210 are separated toward each other, and the monitoring probe 18 can be moved up and taken out, thereby improving the convenience of replacing and installing the monitoring probe 18 of the monitor. The two semicircular chambers 210 are evenly spaced with multiple mesh holes. These chambers 210 are made of a heat-dissipating material, specifically aluminum. These meshed, aluminum chambers 210 improve the heat dissipation of the monitoring probe 18 and reduce heat accumulation during operation. A magnetic block 211 is fixedly connected to the side of the mating block 29 facing away from the semicircular chamber 210. An electromagnet bar 212 is fixedly connected to a position within the cavity plate 1 corresponding to the magnetic block 211. The electromagnet bar 212 is located directly below the magnetic block 211. A gap exists between the end of the electromagnet bar 212 closest to the mating block 29 and the mating block 29, allowing space for the mating block 29 to slide on the slotted plate 25. When energized, the magnetic properties of the electromagnet bar 212 are opposite to those of the magnetic block 211, and the electromagnet bar 212 is located in the horizontal movement path of the magnetic block 211.

[0022] During use: When the sole of the child's foot contacts the upper surface of the foot-attaching cavity plate 1, since the monitoring probe 18 is initially located above the through-hole 101, the sole of the child's foot will first contact the monitoring probe 18, and in the process of contact between the sole of the foot and the foot-attaching cavity plate 1, the monitoring probe 18, the semicircular cabin 210, and the matching block 29 will slide downward, and the spring 28 will be in a compressed state during this process. After the sole of the child's foot contacts the upper surface of the foot-attaching cavity plate 1, the spring 28 in a compressed state will always give the matching block 29, the semicircular cabin 210, and the monitoring probe 18 an upward elastic force, so that the monitoring probe 18 fits tightly against the sole of the child's foot, and then makes full contact with the sole of the child's foot, so that the monitoring probe 18 can effectively monitor the child's blood oxygen saturation.

[0023] Then, while the monitoring probe 18 is monitoring, the medical staff can control the timing of the small motor 22 to start and stop through the timing controller 17. When the small motor 22 is started, it drives the reciprocating screw 23 to rotate. The rotation of the reciprocating screw 23 then drives the displacement plate 24 to move horizontally along the track of the limit slot toward the side away from the small motor 22, thereby indirectly driving the synchronous displacement of the monitoring probe 18 and the magnetic block 211.

[0024] As the magnetic block 211 moves horizontally with the monitoring probe 18 away from the small motor 22, the timing controller 17 simultaneously energizes the electromagnet 212. Under the opposite magnetic force of the electromagnet 212 and the magnetic block 211, the magnetic block 211 vertically moves downward toward the electromagnet 212, thereby driving the matching block 29, the semicircular cabin 210, and the monitoring probe 18 to continue to move downward, thereby temporarily separating the monitoring probe 18 from the child's foot. When the monitoring probe 18 moves to the fixed position, the electromagnet 212 is de-energized. At this point, the magnetic block 211 and the electromagnet 212 are no longer magnetically attracted to each other. Consequently, the rebound force of the spring 28 drives the matching block 29, the semicircular cabin 210, and the monitoring probe 18 to automatically move upward, allowing the monitoring probe 18 to contact the child's foot again. Therefore, by timing the small motor 22 to start and stop at regular intervals by the timing controller 17, the monitoring probe 18 can be driven to automatically change its position, that is, change the monitoring position of the monitoring probe 18 on the sole of the child's foot. When the displacement plate 24 moves to the position where the electromagnet bar 212 is farthest from the small motor 22, the small motor 22 starts to drive the reciprocating screw 23 to continue rotating, which will cause the displacement plate 24 to gradually shift in the opposite direction and reset, thereby causing the monitoring probe 18 and other components to shift in the opposite direction. Therefore, by using the timing controller 17 to control the small motor 22 to start and stop at regular intervals, the monitoring probe 18 can be driven to automatically change its monitoring position on the sole of the child's foot, thereby avoiding the local pressure and discomfort caused by the monitoring probe 18 monitoring at the same position on the sole of the child's foot for a long time, thereby improving the child's comfort during the monitoring process. At the same time, the monitoring probe 18 does not contact the sole of the child's foot during the repositioning process, reducing the risk of friction damage to the sole of the child's foot caused by moving the monitoring probe 18. Moreover, the automatic change of the monitoring position of the monitoring probe 18 allows monitoring at different positions on the sole of the child's foot, thereby improving the comprehensiveness of the blood oxygen saturation monitoring data.

[0025] Example 2: The pulse oximetry monitor for children, such as Figure 7 、 Figure 8As shown, it also includes a matching ventilation mechanism provided on one side of the inner plate 21. The matching ventilation mechanism includes a cylinder 31 fixedly connected to the bottom surface of the inner cavity of the cavity plate 1. The cylinder 31 is rotatably connected to a rotating shaft 32. The rotating shaft 32 is located on the side close to the small motor 22. The output shaft of the small motor 22 and the rotating shaft 32 are both fixedly connected to a synchronous wheel 33. A synchronous belt 34 is connected between the two synchronous wheels 33. The side of the rotating shaft 32 close to the cylinder 31 is fixedly connected to a fan blade 35. The fan blade 35 is located inside the cylinder 31. The side of the cylinder 31 away from the rotating shaft 32 is fixedly connected to a combination pipe 36. The end of the combination pipe 36 away from the cylinder 31 is fixedly connected to an air outlet nozzle 37. The combination pipe 36 and the air outlet nozzle 37 are both made of hard PVC. Specifically, the combined pipe 36 is composed of two connecting pipes, one of which is connected to the cylinder 31, and the other is connected to the air outlet nozzle 37. The air outlet nozzle 37 is provided with a rectangular opening on the side away from the connecting pipe. The rectangular opening of the air outlet nozzle 37 is horizontally located on one side below the monitoring probe 18 and the semicircular cabin 210.

[0026] During use: At the same time, when the above-mentioned small motor 22 starts to drive the reciprocating screw 23 to rotate, it will also drive a synchronous wheel 33 fixedly connected to the small motor 22 to rotate synchronously, thereby driving another synchronous wheel 33 on the rotating shaft 32 to rotate synchronously through the cooperation of the synchronous wheel 33 and the synchronous belt 34, thereby driving the fan blades 35 to rotate synchronously, and after the fan blades 35 rotate, the air in the external environment of the foot cavity plate 1 will be drawn into the foot cavity plate 1 from the heat dissipation holes 102, and the external air will be sent into the air outlet nozzle 37 from the combination pipe 36 through the fan blades 35 and the cylinder 31, and finally the external air will be blown out from the air outlet nozzle 37 toward the bottom of the monitoring probe 18 and the semicircular cabin 210, thereby taking away the heat around the monitoring probe 18 and the semicircular cabin 210. Therefore, through the cooperation of the fan blades 35, the air outlet nozzle 37 and other components, when the monitoring probe 18 changes its monitoring position, the heat around the monitoring probe 18 and the semicircular cabin 210 will be taken away, avoiding excessive heat accumulation around the two and causing burns to the soles of the children's feet, thereby improving the safety of the monitoring operation of the monitoring probe 18. At the same time, since the fan blades 35 will only operate synchronously when the monitoring probe 18 changes its position regularly, it also avoids the situation where the soles of the children's feet become too cold due to long-term continuous heat dissipation, thereby reducing the discomfort caused to the children.

[0027] Example 3: Pulse oximetry monitor for pediatric monitoring, such as Figure 1 、 Figures 9 to 12As shown, it also includes a wiping replacement mechanism set in the inner cavity of the foot cavity plate 1. The wiping replacement mechanism is located on both sides below the through-hole 101. The wiping replacement mechanism includes two bottom plates 41 plugged into the bottom surface of the foot cavity plate 1. The bottom surface of the foot cavity plate 1 is provided with rectangular openings at positions corresponding to the two bottom plates 41, and the two bottom plates 41 are tightly plugged into the rectangular openings. The top surface of the inner cavity of the foot cavity plate 1 is evenly connected to four slotted disks 1 42, and each of the four slotted disks 1 42 is plugged with a storage disk 43. A cross plug is fixedly provided on the side of the storage disk 43 close to the slotted disk 1 42, and a cross socket is provided on the slotted disk 1 42 to match the cross plug, and the cross plug is tightly plugged into the cross socket. The storage tray 43 is located above a base plate 41. A ratchet disc 44 is fixedly connected to the bottom surface of the storage tray 43. A T-shaped plate 45 is fixedly connected to the side of the slotted plate 25 near the ratchet disc 44, away from the monitoring probe 18. A torsion spring pawl 46 is evenly and rotatably connected to the side of the T-shaped plate 45 away from the slotted plate 25. The torsion spring pawl 46 includes a plate body fixedly connected to the T-shaped plate 45, on which a pawl is rotatably connected. The side of the pawl near the plate body is in contact with the outer surface of the plate body, which is used to limit the rotation direction of the pawl. A torsion spring is connected to the portion where the pawl is rotatably connected to the plate body. The ratchet disc 44 is located on the horizontal movement path of the torsion spring pawl 46. Four slotted discs 2 47 are evenly and rotatably connected at a position corresponding to the inner cavity of the cavity plate 1 and the other base plate 41. Each of the four slotted discs 2 47 is plugged into a winding disc 48, which is tightly plugged into the slotted disc 2 47. A cotton strip 49 is wound on the winding disk 48, and one end of the cotton strip 49 away from the winding disk 48 is adhered to the storage disk 43. The portion of the cotton strip 49 between the winding disk 48 and the storage disk 43 is horizontal, and the initial position of the cotton strip 49 on the horizontal portion is located in the through-opening 101, and the position of the cotton strip 49 on the horizontal portion is lower than the position of the monitoring probe 18, and the cotton strip 49 on the horizontal portion is located on the path of horizontal movement of the monitoring probe 18, that is, after the monitoring probe 18 moves downward and then moves horizontally, its upper surface can be in contact with the lower surface of the cotton strip 49. A through groove for the cotton strip 49 to pass through is provided at the position corresponding to the foot cavity plate 1 and the cotton strip 49, and the through groove is arranged on both sides of the through-opening 101. A slot block 491 is fixedly connected to the position corresponding to the foot cavity plate 1 and the cotton strip 49. Specifically, the slot block 491 is located on the two side walls of the through-opening 101, and the slot block 491 corresponds to the cotton strip 49 one by one. The slot block 491 is made of elastic rubber material, and the cotton strip 49 passes through the slot block 491. The slot block 491 is used to ensure that the height of the cotton strip 49 located in the through-opening 101 is stable, but it will not affect the winding of the cotton strip 49.

[0028] During use: Considering that the monitoring probe 18 may become stained with sweat when it is in contact with the sole of a child's foot during monitoring, sweat can affect the monitoring effect of the monitoring probe 18. Therefore, when the monitoring probe 18 in the first embodiment moves downward and changes position horizontally, it enters the foot-attaching cavity plate 1 through the through-hole 101, allowing the upper surface of the monitoring probe 18 to contact the bottom surface of the cotton strips 49 in the horizontal portion. As the monitoring probe 18 moves horizontally, the cotton strips 49 absorb sweat from the upper surface of the monitoring probe 18. After the monitoring probe 18 changes position horizontally, it is positioned between two adjacent cotton strips 49, preventing contact between the monitoring probe 18 and the sole of the child's foot. Therefore, the cotton strips 49 absorb sweat from the upper surface of the monitoring probe 18 during the change of position, thereby reducing the impact of sweat on the blood oxygen saturation measured by the monitoring probe 18 and ensuring the effectiveness of the monitoring probe 18.

[0029] At the same time, when the monitoring probe 18 is repositioned, the slotted plate 25 near the side of the positioning ring 15 drives the T-shaped plate 45 to move synchronously, and the torsion spring pawl 46 drives the ratchet disc 44 to rotate, and the ratchet disc 44 drives the storage disc 43 to rotate synchronously. As the storage disc 43 rotates, the tampon 49 is gradually wound onto the storage disc 43, and the unused tampon 49 on the winding disc 48 is automatically released, so that the new unused tampon 49 is in contact with the upper surface of the monitoring probe 18 and absorbs the attached sweat. When the T-shaped plate 45 moves horizontally in the opposite direction along with the displacement plate 24 and the slotted plate 25, the torsion spring pawl 46 does not drive the ratchet disc 44 to rotate in the opposite direction, so that the used tampon 49 on the storage disc 43 will not be released. In this way, by utilizing the cooperation of the torsion spring pawl 46, the storage tray 43 and other components, the used tampon 49 can be automatically rolled up and the unused tampon 49 can be automatically released during the process of changing the position of the monitoring probe 18, thereby ensuring the effectiveness and sustainability of the subsequent sweat absorption by the tampon 49.

[0030] Furthermore, after use of the monitor, the medical staff can remove the monitor from the child's foot. The two bottom plates 41 are then opened, and the medical staff can grasp the cotton strip 49 and apply an external force greater than the elastic force of the slot block 491 to separate the cotton strip 49 from the slot block 491. The medical staff can then separate the receiving tray 43 from the slotted tray 1 42 and the winding tray 48 from the slotted tray 2 47. The receiving tray 43 and the winding tray 48 can then be removed from the foot-attached cavity plate 1, and the cotton strip 49 can be removed from the receiving tray 43 and the winding tray 48 and discarded. When the cotton strip 49 needs to be installed again, a new cotton strip 49 is wound on the winding disk 48, leaving a section of the cotton strip 49 not wound on the winding disk 48, and then the winding disk 48 and the storage disk 43 are respectively inserted back into the slotted disk 2 47 and the slotted disk 1 42, and then the cotton strip 49 wound on the winding disk 48 is pulled through the through slot and the slot block 491, and then the end of the cotton strip 49 not wound on the winding disk 48 is glued to the storage disk 43 with tape, and then the winding disk 48 is rotated so that the part of the cotton strip 49 between the storage disk 43 and the winding disk 48 is in a horizontal state, and then the two bottom plates 41 are inserted back into the bottom of the cavity plate 1, and the replacement of the cotton strip 49 is completed.
