Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a non-invasive ventilation device for infants that prevents bruising and suffocation, and a data processing method thereof. Background Technology

[0002] Currently, there are the following problems with assisted ventilation devices for newborns and children: 1. Non-invasive ventilation often cannot be truly non-invasive. If the non-invasive ventilation time is slightly longer, the child is prone to pressure injuries, including the nasal septum, nasal tip, nostrils and perianal skin.

[0003] 2. The device is difficult to fix, making clinical operation difficult, time-consuming, and prone to falling off and shifting, resulting in unstable air pressure transmitted to the child and affecting ventilation effect.

[0004] 3. Newborns or premature infants have delicate skin that lacks a well-developed protective barrier. Therefore, the delivery tubes need to be thin, flexible, and resistant to bending. However, traditional plastic extrusion tubes cannot simultaneously achieve both thin walls and good bending resistance. If the tubes are too thin, they may not be resistant to bending, posing a risk of suffocation to the infant. If they are too thick, the increased product weight will also significantly increase airflow resistance.

[0005] 4. Because the diameter of the neonatal transmission tube for premature infants is small (and the inner diameter is even smaller), and this section has no heating function, condensation easily forms in the tube. Due to the small inner diameter, even a small amount of condensation can block the tube, causing the infant to suffocate.

[0006] In non-invasive ventilation of infants, traditional devices such as generators and nasal cannulas often present problems such as difficulty in fixation, easy displacement, and pressure injuries. Infant ventilation tubing typically has a small inner diameter, resulting in high resistance and the risk of condensation clogging the tubing and causing suffocation.

[0007] The aforementioned problems combined negatively impact clinical efficiency, increase operational difficulty, and raise concerns about patient comfort and the risk of suffocation. Traditional products often require frequent switching between nasal canisters and masks, the use of hydrocolloid dressings, frequent checks for pressure sores, and placement of the child in an incubator for ventilation, among other auxiliary methods, to minimize pressure sores and ensure effective ventilation. These measures increase operational difficulty, costs, and clinical workload, thus reducing potential harm to the child.

[0008] Therefore, the urgent technical problem to be solved is how to provide a non-invasive ventilation device and data processing method for infants that is resistant to bruising and prevents suffocation, reduces pressure injury to patients, ensures smooth ventilation, is easy to operate, and reduces costs. Summary of the Invention

[0009] The purpose of this application is to provide a non-invasive ventilation device for infants that prevents bruising and asphyxiation, and a data processing method that reduces pressure injury to the patient, ensures smooth ventilation, is easy to operate, and lowers costs.

[0010] To achieve the above objectives, this application provides a non-invasive ventilation device for infants to prevent bruising and suffocation. The device includes: a nasal plug body, a water-permeable but air-permeable spring tube, and a fixing device; one end of the water-permeable but air-permeable spring tube is connected to the nasal plug body, and the other end is connected to an air source interface; the water-permeable but air-permeable spring tube includes: a spring and a pipe shell; the spring is disposed inside the pipe shell; the pipe shell is an elastomer; the fixing device is fixedly connected to the nasal plug body to directly fix the nasal plug body to the patient's face.

[0012] In the non-invasive ventilation device for preventing suffocation and fracture of infants as described above, the nasal plug body has an air vent.

[0013] In the non-invasive ventilation device for infants that is designed to prevent suffocation and fracture, as described above, the thickness of the outer shell of the tube ranges from 0.03 to 0.13 mm.

[0014] As a second aspect of this application, this application provides a data processing method for an anti-bend and anti-asphyxiation non-invasive ventilation device for infants, applied to the aforementioned anti-bend and anti-asphyxiation non-invasive ventilation device. The nasal plug body has an embedded pressure sensor, and the water-permeable but air-permeable spring tube integrates a flow sensor.

[0015] The data processing method for the anti-bending and anti-suffocation non-invasive ventilation device for infants as described above includes the following subroutine for determining suffocation risk: calculating the suffocation risk value based on dynamic airway flow data; comparing the suffocation risk value with a preset suffocation determination threshold; and determining that there is a suffocation risk if the suffocation risk value is greater than the preset suffocation determination threshold.

[0017] The data processing method of the anti-bending and anti-asphyxia infant non-invasive ventilation device described above includes calculating the real-time flow deviation based on the dynamic flow data of the airway. If the real-time flow deviation meets the predetermined warning conditions, an early warning is triggered and the emergency ventilation mode is started.

[0019] The data processing method for the anti-bending and anti-asphyxia non-invasive ventilation device for infants, as described above, further includes: constructing a risk priority ranking model for multiple infants and dynamically adjusting the monitoring level according to the asphyxia risk value.

One end of the water-permeable but air-permeable spring tube 2 is connected to the nasal plug body 1, and the other end is connected to an air source interface. The water-permeable but air-permeable spring tube 2 includes: a spring and a pipe shell. The spring is disposed inside the pipe shell. The pipe shell is an elastomer. The fixing device 3 is fixedly connected to the nasal plug body 1 to directly fix the nasal plug body 1 to the patient's face.

[0029] like Figure 2 As shown, the fixation device 3 includes: a hydrocolloid dressing 32 and a hook and loop fastener assembly 31; the hook and loop fastener assembly 31 is attached to the nasal plug body 1 by double-sided adhesive; the hydrocolloid dressing 32 is provided with a hook and loop fastener hook side, and the hook and loop fastener assembly 31 is provided with a hook and loop fastener hook side; the hook and loop fastener hook side 33 are connected in a cooperative manner; the hydrocolloid dressing 32 is used to directly fix the nasal plug body 1 to the child's face.

[0030] In a preferred embodiment of the present invention, the nasal plug body 1 has a vent. The vent can be used for non-invasive positive pressure ventilation, has lower airway resistance compared to similar products, and can be used for dual-channel non-invasive ventilation. An external air resistance connector can also be added to replace the generator for single-channel non-invasive ventilation.

[0031] In a preferred embodiment of the present invention, the thickness of the pipe shell ranges from 0.03 to 0.13 mm.

[0032] like Figure 3 As shown, this application provides a data processing method for an anti-bending and anti-asphyxia non-invasive ventilation device for infants, applied to the anti-bending and anti-asphyxia non-invasive ventilation device for infants, wherein a pressure sensor is embedded in the nasal plug and a flow sensor is integrated in a water-permeable but air-permeable spring tube, and the method includes:

[0033] Step S1: Real-time acquisition of perinasal contact pressure distribution data and airway dynamic flow data.

[0034] As a specific embodiment of the present invention, a pressure sensor is installed around the nasal plug to collect data on the nasal perinasal contact pressure distribution. A flow monitoring sensor is installed within the tubing of the ventilation device to collect dynamic airway flow data.

[0035] Step S2: Perform Kalman filtering noise reduction on the collected data to eliminate motion artifact interference; if the airway dynamic flow data meets the predetermined risk conditions, start the asphyxiation risk assessment subroutine.

[0036] Specifically, the collected perinasal contact pressure distribution data and airway dynamic flow data were processed using Kalman filtering to reduce noise and eliminate motion artifact interference.

[0037] The predetermined risk condition is: the airway dynamic flow rate data is below 0.3 L / min for 0.5 seconds for 0 consecutive seconds and shows a monotonically decreasing trend.

[0038] The asphyxiation risk assessment subroutine includes the following steps:

[0039] Step S210: Calculate the asphyxiation risk value based on the airway dynamic flow data.

[0040] The formula for calculating the asphyxiation risk value is as follows: ; in, ; in, express The risk of suffocation at any given moment; This indicates the weight of the impact of airway dynamic flow anomaly on the asphyxiation risk value; Represents a conditional factor, if If the dynamic airway flow rate at a given time is less than a predetermined threshold, then ,otherwise, ; Indicates the standard expected ventilation flow rate; express Dynamic airway flow at any given time; ; This represents the weight of the asphyxiation risk value in relation to the rate of change of the current airway dynamic flow rate compared to the previous airway dynamic flow rate. This represents the fluctuation value of normal respiratory ventilation flow rate; This indicates the weighting of the impact of dynamic airway flow fluctuations on the asphyxiation risk value. This represents the airway dynamic flow rate at time i. ; Preferred, Take a positive integer, and . The unit is s.

[0041] This application improves the accuracy of asphyxiation risk calculation and enhances the reliability and safety of ventilation devices.

[0042] Step S220: Compare the suffocation risk value with the preset suffocation judgment threshold. If the suffocation risk value is greater than the preset suffocation judgment threshold, then it is determined that there is a suffocation risk; otherwise, there is no suffocation risk.

[0043] Step S3: Calculate the nasal obstruction displacement index based on the pressure distribution data; if the nasal obstruction displacement index is less than a predetermined first threshold, it is determined to be a fixation failure.

[0044] The formula for calculating the nasal obstruction displacement index is as follows: ; in, Indicates the nasal congestion displacement index; Indicates the number of pressure sensors; This represents the pressure value of the j-th pressure sensor; This represents the contact area between the j-th pressure sensor and the face.

[0045] This application improves the accuracy of nasal obstruction displacement index calculation.

[0046] Step S4: Calculate the real-time flow deviation based on the airway dynamic flow data. If the real-time flow deviation meets the predetermined warning conditions, trigger the warning and start the emergency ventilation mode.

[0047] The formula for calculating real-time traffic deviation is as follows: ; in, Indicates the real-time traffic deviation; This represents the expected reference flow rate (L / min) at time t; This represents the dynamic airway flow rate at time t; Indicates the early warning condition factor; if ,but ;otherwise .

[0048] This application improves the accuracy of real-time flow deviation calculation, thereby enabling early warning judgment, activating emergency ventilation mode, and improving the safety of ventilation device use.

[0049] Step S5: Upload the warning information and physiological parameters to the NICU central monitoring system via Bluetooth Low Energy.

[0050] Specifically, if the real-time flow deviation meets the predetermined warning conditions, the warning information and the user's physiological parameters will be uploaded to the NICU central monitoring system for subsequent reference.

[0051] As a specific embodiment of the present invention, the method further includes: A risk priority ranking model for multiple children was constructed, and the monitoring level was dynamically adjusted according to the asphyxiation risk value. The higher the asphyxiation risk value, the higher the monitoring level.
