Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent temperature-controlled light therapy swaddling cloth and a dynamic control system for jaundice treatment. Background Art

[0002] Neonatal jaundice refers to a group of diseases caused by excessive bilirubin in the newborn's body. In severe cases, it can cause damage to the neonatal nervous system and lead to bilirubin encephalopathy, affecting the intellectual development of the newborn. Light therapy treats neonatal jaundice by irradiating the skin with light. When blue light is irradiated, the bilirubin in the superficial layer of the skin absorbs light and its structure changes from fat-soluble to water-soluble, which changes the metabolic pathway of bilirubin in the body and can be excreted from bile and urine, thereby alleviating neonatal jaundice.

[0003] Currently, the treatment of jaundice mainly uses equipment such as phototherapy boxes, but phototherapy boxes are large and difficult to move.

[0004] It is not portable enough and needs to be treated at a fixed location. A patent with application number CN2010206206344 discloses a flexible jaundice phototherapy blanket, which includes an external power supply device and a transparent and bendable phototherapy blanket. The phototherapy blanket is provided with multiple blue light-emitting devices, and the light-emitting devices are electrically connected to the external power supply device.

[0005] The above-mentioned technical solution is portable and can treat jaundice through blue light. However, its simple structure makes it impossible to control the temperature. Furthermore, the direct contact between the light-emitting device and the newborn's skin can cause discomfort to the newborn. Furthermore, it cannot be dynamically adjusted according to the treatment needs of jaundice. Therefore, there is an urgent need to develop an intelligent temperature-controlled light therapy swaddling and a dynamic control system for jaundice treatment. Summary of the Invention

[0006] The purpose of the present invention is to provide an intelligent temperature-controlled phototherapy swaddling and a dynamic control system for jaundice treatment to solve the problems of the inability to control temperature and discomfort caused to newborns raised in the background art.

Several two-position three-way solenoid valves are arranged on the main delivery pipeline, and the other two interfaces of the two-position three-way solenoid valve are respectively connected to the auxiliary delivery pipeline and the return pipeline. The auxiliary delivery pipeline is connected to one or more adjacent transparent elastic airbags. The two-position three-way solenoid valve is used to change the connection state between the main delivery pipeline and the auxiliary delivery pipeline to a connection between the auxiliary delivery pipeline and the return pipeline, and the return pipeline is connected to the heating assembly.

[0011] Preferably, the swaddling body comprises: an outer fabric; a breathable and heat-insulating layer arranged inside the outer fabric, and a transparent elastic airbag and a blue light-emitting component are arranged on the breathable and heat-insulating layer.

[0012] Preferably, the bottom of the transparent elastic airbag is provided with a first inner recess for placing the blue light emitting component, and the blue light emitting component is arranged in the first inner recess at the bottom of the transparent elastic airbag.

[0013] Preferably, the blue light emitting component is an LED blue light strip, which emits blue light with a wavelength of 425-475nm, and the control component controls the operation of the LED blue light strip through PWM dimming.

[0014] Preferably, a second inner recess for mounting a first sensor is provided on the top of the transparent elastic airbag, and the first sensor is a SHT30-DIS-B temperature and humidity sensor.

[0015] Preferably, the heating assembly includes a heating box; an electric heating wire arranged in the heating box; a second sensor and a medium arranged in the box.

[0016] Another object of the present invention is to provide a dynamic control system for jaundice treatment, comprising: the intelligent temperature-controlled phototherapy swaddling cloth described in any one of the above items; a bilirubin detection device; a host computer; wherein,

[0017] The host computer is electrically connected to the control component of the intelligent temperature-controlled phototherapy swaddle in a wired or wireless manner. The bilirubin detection device is used to monitor the total bilirubin level of the newborn and manually or automatically transmit the bilirubin level data to the host computer. The host computer is preset with a control program for different blue light intensities and irradiation times corresponding to different bilirubin levels.

[0020] The present invention provides an intelligent temperature-controlled phototherapy swaddle, which, by adding components such as a transparent elastic airbag and an electrical control box, can fill a heated medium into the transparent elastic airbag to maintain a stable body temperature for the newborn. When the temperature in the transparent elastic airbag drops, the low-temperature medium flows back to the heating component through a return pipe to be reheated, and the medium at a preset temperature is refilled into the transparent elastic airbag, thereby regulating the newborn's body temperature. The back-and-forth contraction of the transparent elastic airbag can not only massage the newborn, but also inhale dry air from the outside into the swaddle itself, thereby reducing the frequency of sweating in the newborn, keeping the body dry, and improving comfort.

Based on the above-mentioned intelligent temperature-controlled phototherapy swaddling, the total bilirubin of the newborn is measured by a bilirubin detection device, and the measurement results are input into the host computer. The host computer selects the appropriate blue light intensity and blue light exposure time according to the total bilirubin amount and sends them to the control component. The control component controls the blue light intensity and illumination time of the LED blue light strip through PWM dimming, thereby dynamically regulating the jaundice treatment. Thanks to the expansion and contraction of the transparent elastic airbag during operation, the newborn's body remains dry and refreshed, and there is no sweat and water vapor that affects the blue light treatment, thereby enabling more precise control.

[0030] The following is a preferred embodiment of an intelligent temperature-controlled light therapy swaddling cloth:

[0031] An intelligent temperature-controlled light therapy swaddle, such as Figure 1-2 As shown, it includes: a swaddling body 100; a transparent elastic airbag 200 provided on the inner wall of the swaddling body 100; a first sensor 300 provided on the transparent elastic airbag 200; a blue light emitting component 400 provided on the inner wall of the swaddling body 100; and an electric control box 500 connected to the swaddling body 100;

[0032] The electrical control box 500 includes: a box body 510; a delivery pump assembly 520, a heating assembly 530, a control assembly 540, and a power supply assembly 550 arranged in the box body 510; the delivery pump assembly 520 is connected to the transparent elastic airbag 200, and the delivery pump assembly 520 is connected to the heating assembly 530, and the delivery pump assembly 520 is used to deliver the heated medium in the heating assembly 530 to the transparent elastic airbag 200; the control assembly 540 is electrically connected to the blue light emitting assembly 400, the delivery pump assembly 520, the heating assembly 530, and the first sensor 300; the power supply assembly 550 is used to power the intelligent temperature-controlled phototherapy swaddle.

[0033] During operation, the preset temperature is set through the control component 540, and the control component 540 controls the operation of the heating component 530. The heating component 530 heats the medium in the heating component 530 to the preset temperature. The delivery pump component 520 pumps the heated medium into the transparent elastic airbag 200 to heat the transparent elastic airbag 200. The first sensor 300 detects the body temperature of the newborn. When the body temperature reaches the preset temperature, the control component 540 controls the heating component 530 to work intermittently to maintain the current temperature, thereby achieving temperature regulation.

[0034] As an embodiment of the present invention, Figure 4 As shown, the delivery pump assembly 520 includes a pump body 521, a main delivery pipeline 522, a two-position three-way solenoid valve 523, an auxiliary delivery pipeline 524, and a return pipeline 525. The suction end of the pump body 521 is connected to the heating component 530, and the output end of the pump body 521 is connected to the main delivery pipeline 522. Several two-position three-way solenoid valves 523 are provided on the main delivery pipeline 522. The other two interfaces of the two-position three-way solenoid valve 523 are respectively connected to the auxiliary delivery pipeline 524 and the return pipeline 525. The auxiliary delivery pipeline 524 is connected to one or more adjacent transparent elastic airbags 200. The two-position three-way solenoid valve 523 is used to change the connection state between the main delivery pipeline 522 and the auxiliary delivery pipeline 524 to the connection between the auxiliary delivery pipeline 524 and the return pipeline 525. The return pipeline 525 is connected to the heating component 530.

[0035] When the heating component 530 is heated, the pump body 521 pumps the medium in the heating component 530 into the main delivery pipeline 522, and the two-position three-way solenoid valve 523 is in the closed state. At this time, the main delivery pipeline 522 is connected to the auxiliary delivery pipeline 524, and the heated medium is pumped into the transparent elastic airbag 200. The transparent elastic airbag 200 expands and contacts the body of the newborn. When the first sensor 300 detects that the temperature drops to above the threshold, the control component 540 opens the two-position three-way solenoid valve 523. At this time, the auxiliary delivery pipeline 524 is connected to the return pipeline 525. The transparent elastic airbag 200 shrinks due to its own elastic action, and the low-temperature medium inside flows back to the heating component 530 through the return pipeline 525. The control component 540 closes the two-position three-way solenoid valve 523 again, and the pump body 521 pumps the heated medium into the transparent elastic airbag 200 again.

[0036] As an embodiment of the present invention, Figure 2 As shown, the swaddling body 100 includes: an outer fabric 110; a breathable and heat-insulating layer 120 arranged in the outer fabric 110, and a transparent elastic airbag 200 and a blue light emitting component 400 are arranged on the breathable and heat-insulating layer 120.

[0037] As an embodiment of the present invention, Figure 3 As shown, a first inner recess 210 for placing the blue light emitting component 400 is provided at the bottom of the transparent elastic airbag 200 , and the blue light emitting component 400 is disposed in the first inner recess 210 at the bottom of the transparent elastic airbag 200 .

[0038] As an embodiment of the present invention, the blue light emitting component 400 is an LED blue light strip, which emits blue light with a wavelength of 425-475nm. The control component 540 controls the operation of the LED blue light strip through PWM dimming.

[0039] As an embodiment of the present invention, Figure 3 As shown, the top of the transparent elastic airbag 200 is provided with a second inner recess 220 for installing the first sensor 300. The first sensor 300 is a SHT30-DIS-B temperature and humidity sensor for detecting temperature and humidity. When the newborn sweats, the first sensor 300 detects the humidity value signal and sends it to the control component 540. The control component 540 detects that the humidity signal exceeds the threshold. At this time, the control component 540 controls the corresponding two-position three-way solenoid valve 523 to open, and the volume of the transparent elastic airbag 200 shrinks. During the shrinkage process, the transparent elastic airbag 200 does not contact the newborn's body. At the same time, when shrinking, a negative pressure area will be generated between the newborn and the transparent elastic airbag 200, thereby inhaling the surrounding air. Through this air flow, the volatilization of sweat is accelerated, and the newborn is prevented from sweating in the swaddle and causing discomfort to the newborn.

[0040] As an embodiment of the present invention, the heating component 530 includes a heating box; an electric heating wire arranged in the heating box; a second sensor and a medium arranged in the heating box, wherein the medium is a gaseous fluid or a liquid fluid, such as air, water, coolant, etc. The medium in the box is heated by the electric heating wire, and the second sensor detects the temperature of the medium. When the temperature reaches a preset value, heating is stopped. When the temperature is lower than the preset value, the control component 540 controls the electric heating wire to work again.

[0041] As an embodiment of the present invention, the box body 510 is provided with a handle for easy carrying.

[0042] The following also provides a preferred embodiment of a dynamic control system for treating jaundice:

[0043] A dynamic control system for jaundice treatment includes: the above-mentioned intelligent temperature-controlled phototherapy swaddling; a bilirubin detection device; a host computer; the host computer is electrically connected to the control component 540 of the intelligent temperature-controlled phototherapy swaddling by wired or wireless means, the bilirubin detection device is used to monitor the total bilirubin level of the newborn and manually or automatically transmit the bilirubin level data to the host computer, the host computer is preset with a control program for different blue light intensities and irradiation times corresponding to different bilirubin levels, the total bilirubin of the newborn is measured by the bilirubin detection device, the measurement results are input into the host computer, the host computer selects the appropriate blue light intensity and blue light irradiation time according to the total bilirubin level and sends them to the control component 540, the control component 540 controls the blue light intensity and illumination time of the LED blue light strip through PWM dimming, thereby dynamically regulating the jaundice treatment, and using the expansion and contraction of the transparent elastic airbag 200 to keep the newborn's body dry and fresh, without sweat and water vapor affecting the blue light treatment, thereby enabling more precise control.

[0044] The bilirubin detection device is any one of a transcutaneous bilirubin monitoring device, a bilirubin oxidase method monitoring device, and a diazo reagent method monitoring device.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting.
