[0039] In addition, as shown in the accompanying drawings Figure 8 , the accompanying drawings Figure 9 and the accompanying drawings Figure 11 , the clamping pipe 6 is provided with a through groove 601, a connecting rod 602 and an electric control telescopic rod 603; the through groove 601 is arranged on the upper part of the inside of the clamping pipe 6 and slidably connects the sensing parts 5; one end of the connecting rod 602 is fixedly and perpendicularly connected to the upper part of the outside of the clamping pipe 6; the other end of the connecting rod 602 is fixedly connected to the top end of the electric control telescopic rod 603; the electric control telescopic rod 603 is fixedly connected to the top surface of the sensing parts 5 and is electrically connected with the switch 5201; when the switch 5201 is started, the electric control telescopic rod 603 is controlled to work through the controller, the clamping pipe 6 is driven to move downward through the connecting rod 602, and the triggering part 7 cannot work, and when the electric control telescopic rod 603 is extended upward to drive the clamping pipe 6 to move upward, the triggering part 7 can work.

[0040] In addition, as shown in the accompanying drawingsFigure 1 and attached Figure 2 As shown, the incubator body 1 also includes a hanging bracket 13, a side door 101, and a main door 102. The hanging bracket 13 is fixed and vertically erected on the top surface of the main body 12 and the left side of the cover 11. The side door 101 is movably connected to the outer sides of the left and right sides of the cover 11 via a shaft. The main door 102 is movably connected to the outer sides of the cover 11 and the door 2 via a shaft. The hanging bracket 13 allows the incubator to provide a base for hanging bottles for newborns or sick children to receive intravenous infusions. The side door 101 and the main door 102 allow medical staff to perform care operations on newborns or sick children without opening the cover 11 or the door 2 when they need care. This facilitates the entry of hands into the cover 11 while reducing the leakage of gas inside the incubator and ensuring the temperature and humidity balance inside the incubator.

[0041] In addition, as attached Figure 2 Appendix Figure 5 and attached Figure 6 As shown, the door 2 consists of a door panel 21 and a protective ring 22. Two main doors 102 are movably mounted on the outer side of the door panel 21 via a shaft. The protective ring 22 is attached to the edges of two sets of through holes inside the door panel 21, and the inside of the protective ring 22 is filled with gas. After the inside of the incubator 11 is preheated, the newborn or sick child can be placed inside the incubator 11 after opening the door panel 21. The infant placed in the incubator can quickly adapt to the temperature and humidity environment inside the incubator. Only one set of door panels 21 is provided. Compared with traditional incubators with doors on both sides, in the confined space of the hospital in emergency or disaster relief environments, the two sets of incubator bodies 1 are placed close together, and the two sets of door panels 21 are opposite each other. This does not affect the use of the incubator, but can reduce the floor space and increase the number of incubators that can be placed. The protective ring 22 is filled with gas, so that the protective ring 22 forms a small airbag, so that the arms will not be bumped by the edges of the through holes inside the door panel 21 when the hands are operating inside the incubator.

[0042] In addition, as attached Figure 5 Appendix Figure 6 and attached Figure 10As shown, the rear side panels of the door panel 21 and the cover 11 are respectively provided with a fixing ring 2101, a mounting groove 2102 and a retaining plate 2103. The inner wall of the fixing ring 2101 is provided with threads. The sensor 5 is fixedly engaged inside the mounting groove 2102. The retaining plate 2103 is provided above the inside of the mounting groove 2102. A retaining groove is formed between the retaining plate 2103 and the top surface of the mounting groove 2102. The top plate of the sensor 5 is engaged inside the retaining groove. The mounting groove 2102 allows the protective airbag 4 and the sensor 5 to be installed on the door panel 21. The retaining groove between the retaining plate 2103 and the mounting groove 2102 allows the top plate of the sensor 5 to be fixedly engaged. The fixing ring 2101 allows the supporting airbag 3 to pass through the door panel 21 and be inflated or deflated from the outside of the door panel 21. The fixing ring 2101 facilitates sealing the port of the supporting airbag 3 from the outside of the door panel 21.

[0043] In addition, as attached Figure 7 and attached Figure 8 As shown, the protective airbag 4 is equipped with an inflation tube 401, which is fixedly connected to the bottom periphery of the sensor 5. The inflation tube 401 contains an igniter and a gas generator, and the protective airbag 4 is also equipped with ventilation holes. When the sensor 5 senses that the incubator body 1 is subjected to a strong impact or tipping, the sensor 5 transmits a signal to the inflation tube 401, igniting the igniter inside the inflation tube 401. After the igniter is ignited, the sodium azide inside the gas generator is ignited, and the generated nitrogen gas is filtered and blown into the protective airbag 4, causing the protective airbag 4 to expand rapidly, thereby protecting the newborn or sick child. Moreover, after the four sets of protective airbags 4 are fully expanded, they cannot fill the inside of the box cover 11, thus ensuring that the protective airbags 4 will not cause secondary injury to the infant. The ventilation holes on the protective airbag 4 can quickly squeeze out the masonry inside the airbag after the infant collides with the protective airbag 4, avoiding secondary injury.

[0044] In addition, as attached Figure 8 Appendix Figure 9 and attached Figure 11 As shown, the trigger 7 includes a connecting rope 71 and a touch ball 72. One end of the connecting rope 71 is fixedly connected to the top plate of the sensor 5, and the other end of the connecting rope 71 is fixedly connected to the touch ball 72. When the bottom end of the locking tube 6 abuts against the touch ball 72, the touch ball 72 cannot touch the inner wall of the fixed tube 51. When the locking tube 6 moves upward, the touch ball 72 can swing. When the box cover 11 is subjected to a violent impact or tilting, the touch ball 72 touches the inner wall of the fixed tube 51, thereby activating the protective airbag 4 for protection.

[0045] In addition, as attached Figure 8 and attached Figure 11As shown, the sensing member 5 includes a fixed tube 51 and a fixed plate 52, the top plate of the fixed tube 51 is clamped in the clamping groove between the clamping plate 2103 and the mounting groove 2102, the inside of the fixed tube 51 is provided with a collision sensor and a PIR infrared sensor, the collision sensor is electrically coupled with the inflator tube 401, and the PIR infrared sensor is arranged on the main body 12, the fixed plate 52 is fixedly connected to the top of the fixed tube 51, the bottom surface of the fixed plate 52 is provided with a switch 5201, the inside of the switch 5201 is provided with a microcircuit controller, when the inner wall of the fixed tube 51 is touched to trigger the sensor, the inflator tube 401 is started to inflate the protection air bag 4, when the PIR infrared sensor senses that there is a person outside the main body 12, the controller starts the switch 5201, so that the clamping tube 6 can be moved downward, and the trigger member 7 cannot work, if the case cover 11 is subjected to a strong impact or falls at this time, the surrounding people can protect the incubator main body 1, if the PIR infrared sensor senses that there is no infant in the case cover 11, the controller starts the switch 5201, so that the clamping tube 6 can be moved downward, and the trigger member 7 cannot work, if the case cover 11 is subjected to a strong impact or falls at this time, no infant will be injured, so the protection air bag 4 does not need to be started.

[0046] The specific use and role of the embodiment are as follows: in the present application, when the supporting air bag member 3 is clamped to the inner edge of the case cover 11, the air outlet 32 penetrates the fixed ring 2101, the exposed part of the air outlet 32 is inflated by the air pump to inflate the supporting air bag member 3, after the inflation state is adjusted, the sealing cover 33 is used for plugging, after the sealing cover 33 is screwed, the sealing cover 33 is fixedly connected to the fixed ring 2101 through thread engagement, so that the sealing cover 33 can be fixedly connected to the inside of the fixed ring 2101 after plugging the air outlet 32, the tightness of the case cover 11 is ensured, after the inside of the case cover 11 is preheated, the door plate 21 is used to put the newborn or patient into the inside of the case cover 11 after the door plate 21 is opened;

[0047] When the electric control telescopic rod 603 extends upward to drive the clamping tube 6 to move upward, the touch ball 72 can swing, when the case cover 11 is subjected to a strong impact or falls, the touch ball 72 touches the inner wall of the fixed tube 51, the sensing member 5 transmits a signal to the inflator tube 401, the igniter in the inflator tube 401 is ignited, the igniter ignites to ignite the sodium azide in the gas generator, the generated nitrogen gas is filtered and blown into the protection air bag 4, so that the protection air bag 4 rapidly expands and bulges, thereby protecting the newborn or patient.

[0048] Finally, it should be noted that, in the description of the positions of various components and the cooperation relationship therebetween, etc., one component / pair of components is usually taken as an example, however, those skilled in the art should understand that such positions, cooperation relationship, etc. are also applicable to other components / other pairs of components.
