Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically provides a premature infant apnea warning and intervention device and an intervention method. Background Art

[0002] Apnea refers to the absence of respiratory movement for a period of time. For example, if breathing resumes after 5 - 15 seconds of apnea, it is called periodic breathing. If the breathing stops for more than 20 seconds, accompanied by a heart rate decrease of less than 100 beats per minute or the appearance of cyanosis, a decrease in blood oxygen saturation, and hypotonia, it is called apnea. Among premature infants with a weight less than 1.8 kg, the incidence of apnea can reach 20% - 30%; for very low - birth - weight infants (<1.5 kg), the incidence further increases to about 50%. When the weight of ultra - low - birth - weight premature infants is less than 1 kg, the probability of apnea reaches 90%.

[0003] The utility model with the patent number CN215305865U discloses a premature infant apnea warning and treatment device, including an apnea monitor, a pulse signal generator, a relay, a motor, and an inflatable airbag. Among them: the pulse signal generator is coupled with the apnea monitor and receives the electrical signal sent by the apnea monitor; the relay is coupled with the pulse signal generator, receives the electrical signal sent by the pulse signal generator, and outputs an electrical signal to control the motor; the motor is coupled with the relay to inflate the inflatable airbag and lift the back of the premature infant upward. The premature infant apnea warning and treatment device provided by this utility model can assist medical staff in timely warning and treating premature infants with apnea, avoiding time lag, achieving timely treatment, and reaching the best treatment effect.

[0004] The above - mentioned device inflates the inflatable airbag to lift the back of the premature infant upward. However, in the prior art, medical staff need to manually adjust the intensity and frequency of tactile stimulation according to the weight of the premature infant. However, premature infants generally gain three to five catties in weight within 28 days after birth, and the weight gain is relatively rapid. It is difficult for medical staff to constantly monitor the weight changes of several premature infants and timely adjust the appropriate tactile stimulation intensity, which requires increased supervision efforts and occupies a large amount of human resources.

[0014] An apnea warning and intervention device and intervention method for premature infants: Preferably,

[0015] S1: First, place the premature infant on the airbag pad and fix it with a medical strap. Then, attach the vibration sensor to the abdomen of the premature infant. The weight of the premature infant drives the lid of the box to move down a certain distance, thereby driving the judgment mechanism to move. The movement of the judgment mechanism drives the tactile stimulation mechanism to adjust the corresponding length, so that the tactile stimulation mechanism adaptively adjusts the resistance force on the back of the premature infant. And the downward movement of the lid synchronously drives the wedge rod to move down. The wedge rod touches the speed regulating mechanism, so that the speed regulating mechanism adaptively adjusts the frequency of the reciprocating mechanism driving the slide plate to move. The movement of the slide plate drives the tactile stimulation mechanism to move reciprocally synchronously, so as to adapt to the tactile stimulation intensity of premature infants with different weights.

[0016] S2: Judge that the abdomen stops rising and falling through the vibration sensor. When the premature infant stops breathing for 20 seconds, transmit an electrical signal to the apnea monitor and alarm through the speaker.

[0017] S3: Then, control the tactile stimulation mechanism and the speed regulating mechanism to work through the apnea device to perform tactile stimulation on the back of the premature infant, stimulate the back to activate the mechanoreceptors of the skin and muscles, transmit signals to the medullary respiratory center, and trigger the restoration of spontaneous breathing.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) The present invention realizes adaptive adjustment of the extended length of the plug-in rod according to the weight of the premature infant by providing a plurality of stimulating soft rods, a plurality of plug-in rods, a plurality of hollow rods, a main pipe, a driving shaft, a driving motor, a connecting pipe, a third piston column and a pipe sleeve, thereby achieving the goal of changing the resistance of the stimulating soft rod to the back of the premature infant according to the weight of the premature infant. For premature infants with a lighter weight, whose tactile nerves are not mature enough, they need a slightly larger tactile stimulation than that of heavier premature infants. In addition, as the weight of the premature infant increases, the retraction distance of the corresponding plug-in rod increases synchronously. When the driving motor drives the driving shaft to maintain a constant speed, the frequency of the corresponding stimulating soft rod resisting the back of the premature infant will be adaptively slightly increased, so that the tactile stimulation frequency of premature infants weighing less than 1.5 kg is adjusted more smoothly, avoiding discomfort to premature infants caused by excessive adjustment.

[0020] (2) The present invention realizes that the soft rod is stimulated to perform circular motion while the slide plate drives the entire rod to perform reciprocating linear motion by means of the first bevel gear, the second bevel gear, the sliding block, the inclined groove, the speed regulating motor, the mounting plate, the wedge block and the inclined block, thereby simulating the medical staff's technique of patting the back and stroking to relieve the breath. When the weight of a premature infant reaches 1.5 kg, the tactile nerve development is relatively complete and the tactile perception is more acute. At this time, the reciprocating motion speed of the slide plate is adaptively increased to ensure that the tactile stimulation is more obvious. The simulated stroking and relieving breath speed with better tactile stimulation is used for premature infants of different weights to achieve the best sleep apnea intervention effect.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 An embodiment provided by the present invention: A premature infant apnea warning and intervention device includes an apnea monitor 1 and an incubator 2. The end of the apnea monitor 1 is electrically connected to a vibration sensor 4. A judgment mechanism 6 is arranged inside the incubator 2. A box cover 10 is fixedly arranged on the top of the judgment mechanism 6. An airbag pad 9 is arranged on the top of the box cover 10. A wedge-shaped rod 13 is fixedly arranged on the bottom of the box cover 10. A slide plate 11 is slidably arranged at the bottom of the incubator 2. A tactile stimulation mechanism 7 is arranged on the slide plate 11. A reciprocating mechanism 8 is arranged at the bottom inside the box body. A speed regulation mechanism 5 is arranged on the side wall of the box body. A speaker 12 is arranged on the side wall of the apnea monitor 1.

[0030] Specifically, the judgment mechanism 6 includes four hollow cylinders 61, four first springs 62, four first piston columns 63, two second piston cylinders 64, two second piston columns 65, two telescopic rods 66 and a third piston column 67. The four hollow cylinders 61 are fixedly arranged inside the insulation box 2, the four first piston columns 63 are fixedly arranged at the bottom of the box cover 10, the four first springs 62 are respectively arranged inside the corresponding hollow cylinders 61, the two piston cylinders are respectively fixedly communicated and arranged on the side walls of two of the hollow cylinders 61, the two second piston columns 65 are respectively inserted and arranged inside the two piston cylinders, the two telescopic rods 66 are respectively fixedly arranged on the side walls of the two piston columns, and the third piston column 67 is fixedly arranged between the two telescopic rods 66. By placing the premature infant on the airbag pad 9, under the gravity of the premature infant on the box cover 10, the first piston column 63 is driven to move downward and compress the first spring 62, and the air inside the hollow cylinder 61 is squeezed out to the second piston cylinder 64, driving the second piston column 65 to extend out of the second piston cylinder 64, and synchronously driving the telescopic rod 66 and the third piston column 67 to move synchronously.

[0031] Specifically, the two second piston columns 65 are respectively in piston fit with the two second piston cylinders 64.

[0032] Specifically, the tactile stimulation mechanism 7 includes a plurality of stimulating soft rods 71, a plurality of plug-in rods 72, a plurality of hollow rods 73, a main pipe 74, a driving shaft 75, a driving motor 76, a connecting pipe 77 and a pipe sleeve 78. The inner side wall of the warming box 2 is provided with a slider 761 for limited sliding. The driving motor 76 is fixedly arranged on the slider 761. The driving shaft 75 is fixedly arranged at the end of the output shaft of the driving motor 76. The main pipe 74 is rotatably arranged at the end of the driving shaft 75. A sealing sleeve 741 is provided at the rotational connection between the main pipe 74 and the driving shaft 75. The sealing sleeve 741 is fixedly connected to the driving shaft 75. The connecting pipe 77 is fixedly arranged at the bottom of the main pipe 74. A plurality of the hollow rods 73 are fixedly arranged on the sealing sleeve 741 in a circular array and are connected with the main pipe 74. A plurality of the plug-in rods 72 are respectively plugged in the corresponding hollow rods 73. A plurality of the stimulating soft rods 71 ​​are respectively fixedly arranged at the ends of the plug-in rods 72. The pipe sleeve 78 is fixedly connected and arranged at the end of the connecting pipe 77. The movement of the third piston rod 67 forms a negative pressure inside the tube sleeve 78, so that the oil inside is sucked into the tube sleeve 78, so that the plug rod 72 retracts a certain distance from the hollow rod 73. When it is determined that apnea occurs for 20 seconds, the apnea monitor 1 controls the output shaft of the drive motor 76 to rotate, driving the drive shaft 75, the hollow rod 73, the plug rod 72 and the stimulating soft rod 71 to rotate synchronously. It is worth noting that the box cover 10 is provided with a through groove for the stimulating soft rod 71 to contact the back of the premature infant through the airbag cushion 9; the plug rod 72 is adaptively adjusted according to the weight of the premature infant. The extended length of the rod 72 can achieve the effect of changing the resistance of the stimulating soft rod 71 to the back of the premature infant according to the weight of the premature infant. The tactile nerves of premature infants with lighter weight are not fully developed, and they need slightly greater tactile stimulation than those of heavier premature infants. In addition, as the weight of the premature infant increases, the retracted distance of the corresponding plug-in rod 72 increases synchronously. When the drive motor 76 drives the drive shaft 75 to maintain a constant speed, the frequency of the corresponding stimulating soft rod 71 contacting the back of the premature infant will adaptively increase slightly, thereby meeting the differences in sleep apnea intervention for premature infants of different weights.

[0033] Specifically, the third piston rod 67 is piston-plugged with the pipe sleeve 78, and the hollow rod 73, the main pipe 74, the connecting pipe 77 and the pipe sleeve 78 are filled with oil.

[0034] Specifically, the reciprocating mechanism 8 includes a reciprocating screw rod 81 and a fixed plate 82 . The fixed plate 82 is fixedly arranged inside the thermal insulation box 2 . The reciprocating screw rod 81 is fixedly arranged through the fixed plate 82 . The reciprocating screw rod 81 is meshed with the slide plate 11 .

[0035] Specifically, the speed regulation mechanism 5 includes a first bevel gear 51, a second bevel gear 52, a sliding block 53, an inclined slot 54, a speed regulation motor 55, a mounting plate 56, a wedge block 57, an inclined block 58 and a reset assembly. The first bevel gear 51 is fixedly arranged at the end of the reciprocating lead screw 81. The mounting plate 56 is fixedly arranged inside the warming box 2. The inclined slot 54 is arranged on the mounting plate 56. The inclined block 58 is limited and slidably arranged in the inclined slot 54. The sliding block 53 is fixedly arranged at the top of the inclined block 58. The speed regulation motor 55 is fixedly arranged on the sliding block 53. The second bevel gear 52 is fixedly arranged at the end of the output shaft of the driving motor 76. The wedge block 57 is fixedly arranged on the side wall of the sliding block 53. The reset assembly is arranged on the side wall of the wedge block 57. When the box cover 10 moves downward, it drives the wedge rod 13 to move downward. After the wedge rod 13 moves downward a certain distance, it abuts against the wedge block 57. It should be noted that when the weight of the premature infant reaches 1.5 kilograms, the wedge rod 13 abuts against the wedge block 57. The wedge block 57 drives the inclined block 58 to slide inside the inclined slot 54, synchronously driving the sliding block 53, the speed regulation motor 55 and the second bevel gear 52 to move synchronously, so that the transmission ratio between the first bevel gear 51 and the second bevel gear 52 increases. The output shaft of the speed regulation motor 55 rotates to drive the second bevel gear 52 to rotate. The second bevel gear 52 rotates to drive the first bevel gear 51 to rotate. The first bevel gear 51 rotates to drive the reciprocating lead screw 81 to rotate. The reciprocating lead screw 81 rotates to drive the slide plate 11 to move. The slide plate 11 moves to drive the drive shaft 75 to move synchronously, so as to cooperate with the circular motion of the stimulating soft rod 71 to perform intermittent tactile stimulation on the back of the premature infant; it realizes the adaptive adjustment of the corresponding optimal tactile stimulation frequency and method according to the premature infants of different weights. While the stimulating soft rod 71 performs circular motion, the slide plate 11 drives its whole to perform reciprocating linear motion, so as to simulate the techniques of medical staff patting the back and stroking to relieve qi. When the weight of the premature infant reaches 1.5 kilograms, its tactile nerves are more developed and the tactile perception is more sensitive. At this time, the reciprocating motion speed of the slide plate 11 is adaptively increased to ensure that the tactile stimulation feeling is more obvious. For premature infants of different weights, the simulated stroking speed with better tactile stimulation feeling is adopted to achieve the best apnea intervention effect.

[0036] Specifically, the reset assembly includes a reset spring 59 and a side plate 510. The side plate 510 is fixedly arranged inside the warming box 2. The two ends of the reset spring 59 are respectively fixedly arranged on the side plate 510 and the side wall of the wedge block 57. After use, the reset spring 59 pulls the wedge block 57 to reset.

[0037] A premature infant apnea warning and intervention device and an intervention method, comprising:

[0038] S1: First, place the premature infant on the airbag pad 9 and fix it with a medical strap. Then, attach the vibration sensor 4 to the abdomen of the premature infant. The weight of the premature infant drives the lid 10 to move downward by a certain distance, thereby driving the judgment mechanism 6 to move. The movement of the judgment mechanism 6 drives the tactile stimulation mechanism 7 to adjust the corresponding length, so that the tactile stimulation mechanism 7 adaptively adjusts the resistance force on the back of the premature infant. And the downward movement of the lid 10 synchronously drives the wedge-shaped rod 13 to move downward. The wedge-shaped rod 13 abuts against the speed regulation mechanism 5, causing the speed regulation mechanism 5 to adaptively adjust the frequency of the reciprocating mechanism 8 driving the slide plate 11 to move. The movement of the slide plate 11 drives the tactile stimulation mechanism 7 to move reciprocally synchronously, so as to adapt to the tactile stimulation intensity of premature infants with different weights;

[0039] S2: Judge that the abdomen stops rising and falling through the vibration sensor 4. When the premature infant stops breathing for 20 seconds, transmit an electrical signal to the apnea monitor 1 and alarm through the speaker 12;

[0040] S3: Then, control the tactile stimulation mechanism 7 and the speed regulation mechanism 5 to work through the apnea device to perform tactile stimulation on the back of the premature infant, stimulate the back to activate the mechanoreceptors of the skin and muscles, and transmit signals to the medulla oblongata respiratory center to trigger the restoration of spontaneous breathing.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
