As shown in fig. 2 and 3, the infant transportation apparatus 1 includes a frame 10, an incubator 11, a thermostat 12, an oxygen supply device 13, a first sign detection device 14, a display control device 15, and a power supply, all of which are provided on the frame 10.

The frame 10 is a mounting carrier for each device, and the bottom of the frame is provided with wheels 100, so that the whole infant transport apparatus 1 can be conveniently moved; a handle 103 may be provided on the frame 10 adjacent the display control 15 to facilitate movement of the infant transport apparatus 1.

The frame 10 further has a first platform 101 for placing the incubator 11, where the incubator 11 is connected to the first platform 101 by a movable connection, and can move on the first platform 101 in a straight line, for example, as shown in fig. 4, in a possible embodiment, a plurality of first rollers 1010 may be disposed on the first platform 101, and convex first guide portions 1011 are disposed on two sides of the first platform 101, and the incubator 11 is supported by the first rollers 1010 and limited by the first guide portions 1011 disposed on two sides thereof, so that the incubator 11 can move along a chute formed between the two first guide portions 1011. In other embodiments, incubator 11 and first platform 101 may also be connected by a rail.

In order to prevent incubator 11 from sliding on first platform 101 during movement, a locking mechanism may be provided on first platform 101 to limit the position of incubator 11, the locking mechanism being capable of fixing the position of incubator 11 on first platform 101 and being manually unlocked so that incubator 11 can slide on first platform 101. In this embodiment, the thermostat 12 is fixedly connected to the incubator 11 and can move in synchronization with the incubator 11, and therefore, the incubator 11 can be locked at the same time by locking the thermostat 12 by the locking mechanism. As a preferred embodiment, referring to fig. 5 and 6, the locking mechanism may adopt a technical scheme that a fixing buckle 110 is provided at one end of a constant temperature device 12, a stand 102 is provided on a first platform 101, a bayonet 1020 is provided on the stand 102 to be in butt joint with the fixing buckle 110, the fixing buckle 110 can be inserted into the bayonet 1020, the locking mechanism comprises a locking piece positioned in the stand 102, a spring against the locking piece and an unlocking button 1021, when the fixing buckle 110 is inserted into the bayonet 1020, the fixing buckle 110 pushes the locking piece to compress the spring downwards, and when the locking piece is aligned with a through hole of the fixing buckle 110, the spring drives the locking piece to be inserted upwards into the fixing buckle 110 to complete locking; pressing the unlock button 1021 may drive the latch to compress the spring downward to disengage the retaining buckle 110, effecting unlocking. Thus, the incubator 11 is more stable during movement and is safer. In other embodiments, the locking mechanism may also be a mechanical lock or an electromagnetic lock, or the like.

As a preferred embodiment, a photoelectric sensor may be provided at the bayonet 1020 for detecting whether the fixing button 110 of the incubator 11 is reliably fixed at the bayonet 1020, for example, whether it is reliably fixed may be judged by detecting the distance between the thermostat 12 and the stand 102. The photoelectric sensor is in communication connection with the display control device 15, and the display control device 15 can display whether the incubator 11 is fixed firmly in real time. If the fixing buckle 110 is improperly fixed to the bayonet 1020 or is accidentally separated from the bayonet during movement, the display control device 15 will prompt and alarm, so as to avoid medical accidents caused by sliding the incubator 11 from the first platform 101 during transportation.

Incubator 11 is for accommodating an infant, and as shown in fig. 3, includes a case 110 adapted for the infant to lie down, and a case cover 111 rotatably connected to case 110. The case cover 111 can be turned over with respect to the case body 110 to open or close the incubator 11, and in a closed state, a closed space isolated from the outside is formed in the incubator 11, thereby facilitating the adjustment and control of the environment in the incubator 11. Preferably, the box body 110 and the box cover 111 of the incubator are made of materials with good heat insulation effect, so that heat exchange between the inside and the outside of the box body is reduced, and the internal environment of the incubator 11 is more stable.

As a preferred embodiment, further referring to fig. 7, the incubator 11 includes a bed 112 disposed in the case 110, the bed 112 includes an arc-shaped concave bed plate 113, and the bed plate 113 of this structure can ensure that the infant lies flat in the middle position of the bed plate 113, and is not easy to roll, so that scanning can be smoothly performed.

The thermostat 12 enables a circulating air flow to be generated in the incubator 11 to control the ambient temperature in the incubator 11 and to supply oxygen to the incubator 11. The thermostat 12 includes a housing 120 connected to the case 110, a temperature sensing probe provided in the incubator 11, and an air filtering device, a fan and a heating device all provided in the housing 120. A gas port 121 is arranged at the top of the shell 120, a gas hole for gas circulation is arranged at the gas port 121, and a flow channel for guiding the movement of the gas flow is arranged in the shell 120. When the fan is operated, external air enters the flow channel in the shell 120 from the air hole, is filtered by the air filtering device and heated by the heating device, and then enters the incubator 11. The temperature sensing probe is used for detecting the temperature inside the incubator 11, and when the temperature is too high or too low, the temperature of the air entering the incubator 11 can be increased or reduced by changing the heating power of the heating device, so that the temperature inside the incubator 11 is constant, and the air filtering device can ensure the cleanliness of the air entering the incubator 11.

In order to make the temperature inside the incubator 11 more uniform, as shown in fig. 7 to 9, the bed 112 has a substantially rectangular parallelepiped shape, including a first end wall 1120 and a second end wall 1121 disposed opposite to each other, and two side walls 1122 between the first end wall 1120 and the second end wall 1121, wherein the first end wall 1120 is closer to the thermostat 12 than the second end wall 1121. An air supply channel 1123 positioned at the bottom of the bed plate 113 is arranged on the first end wall 1120, the air supply channel 1123 is in butt joint with an air supply port on the shell 120 so as to send heated air into the incubator 11, air outlets 1124 are arranged on the second end wall 1121 and the two side walls 1122, air in the air supply channel 1123 can be evenly dispersed into the incubator 11 through the air outlets 1124, and a certain interval is arranged between the air outlets 1124 and the inner wall of the incubator body 110 so as to prevent the air outlets 1124 from being blocked. The first inner wall 1100 of the box 110 opposite to the first end wall 1120 is further provided with a return air inlet 1125 communicated with the casing 120, for exhausting the air in the incubator 11 to realize the circulation flow of the air flow, and preferably, the return air inlet 1125 is located above the bed board 113 and is not directly communicated with the air supply channel 1123.

Since the air supply passage 1123 is located under the bed plate 113, it can directly heat the bed plate 113, making it more comfortable for the infant to lie down, and as a preferred embodiment, it is in direct contact with most of the area of the lower surface of the bed plate 113, for example, the area in direct contact is more than 80% of the area of the lower surface of the bed plate 113, so as to improve heating efficiency; meanwhile, the air outlets 1124 are formed in the three side faces of the bed body 112, three-face air supply can be achieved, and uniformity of the temperature inside the incubator 11 is better. The design of the air port ensures that the internal temperature can be quickly recovered even when the box cover 111 is closed after being opened, the bed board 112 can be quickly heated to the set temperature, and the temperature control effect is better; in addition, the air flow is not directly blown to the baby, so that the baby infant mattress is safer and more comfortable.

The thermostat 12 is connected to the incubator 11 and can slide synchronously with the incubator 11, and since the thermostat 12 needs to scan and image together with the incubator 11, the housing 120 thereof adopts an electromagnetic shielding structure, so that it can be reliably used in a magnetic resonance environment.

It will be appreciated that although the temperature in the incubator 11 is adjusted by taking heated air as an example, the temperature in the incubator 11 may be reduced by directly inputting external cooler air or by providing an air conditioning unit on the frame 10 to generate and input low temperature gas.

The oxygen supply device 13 is used for supplying oxygen to the incubator 11 to ensure the life safety of the infant, and comprises an oxygen bottle, an air-oxygen mixer and a plurality of pipelines, wherein the air-oxygen mixer is used for mixing air and oxygen in proportion, the pipelines are connected between the air-oxygen mixer and an interface 1210 arranged on the gas port 121, and the mixed gas can be sent to the constant temperature device 12, filtered and heated by the constant temperature device 12 and then sent to the incubator 11. The oxygen bottle, the air bottle and the air-oxygen mixer are respectively preferably a non-magnetic oxygen bottle, a non-magnetic air bottle and a non-magnetic air-oxygen mixer, and can be used in a magnetic resonance environment.

The first sign detecting device 14 is used for monitoring signs of the infant, such as heart rate, blood oxygen saturation, pulse and body temperature, and may include a heart rate blood oxygen module installed in the incubator 11, and detect each sign of the infant through a sensor such as a blood oxygen probe and a body temperature probe of the heart rate blood oxygen module. Meanwhile, the heart rate blood oxygen module is in communication connection with an external display control device 15 through a signal wire so as to send detection data to the display control device 15, and the display 150 of the display control device 15 displays the detected numerical value and gives an alarm when abnormality occurs.

The display control device 15 is communicatively connected to each sensor in the incubator 11, for example, to the temperature sensing probe and the heart rate blood oxygen module, and is capable of receiving data from each sensor and displaying the data on the display 150 thereof in real time. The user can implement man-machine interaction through the display 150, so as to perform operations such as modifying parameters, retrieving data, and the like, and preferably, the screen of the display 150 is a touch screen. When the data received by the display control device 15 is abnormal, for example, the temperature in the incubator is too high or too low, an alarm can be given in the form of sound, light and the like to remind the user, and thus, the display control device 15 may further comprise an alarm device such as a buzzer, a warning lamp and the like.

The power supply is used for supplying power to each electrical component on the infant transportation device 1 so that the relevant electrical component can work normally, and the power supply is communicated with the display control device 15, and can display battery information such as electric quantity, battery temperature and the like on the display control device 15 in real time. Preferably, the power supply is a storage battery, and the power supply output port and the charging port of the power supply are independently separated, so that the continuous work can be ensured by using alternating current for charging when the electric quantity of the storage battery is insufficient. The storage battery is provided with an alternating current inverter and can be provided for other alternating current equipment which is not the system.

It will be appreciated that, since the infant transportation apparatus 1 of the present application has the incubator 11 capable of adjusting temperature and supplying oxygen, the environment in the incubator 11 can be adjusted to be similar to or even better than that in a Neonatal Intensive Care Unit (NICU), and when transporting an infant, the environment in the incubator 11 can be adjusted to be consistent with that in the NICU first, then the infant is held in the incubator 11 by entering the NICU, and then the incubator cover 111 is covered, so that the infant transportation apparatus 1 is pushed out of the NICU. The infant's health can be prevented from being influenced by sudden changes in the environment, and meanwhile, the incubator 11 is internally provided with the first sign detection device 14 for monitoring the infant's signs, so that the infant's signs can be monitored in real time in the transportation process, and the safety is higher.

It will be appreciated that since the incubator 11 and the thermostat 12 need to be moved, the cables, air pipes, etc. connected thereto need to be somewhat spare in order to be able to meet the distance of movement of the incubator 11 and the thermostat 12.

When the infant is transferred from the NICU to the infant transfer apparatus 1, the infant transfer apparatus 1 can be pushed to transfer the infant to the imaging apparatus 2 for scanning imaging, as described above, and in this embodiment, the imaging apparatus 2 is a magnetic resonance imaging apparatus, as shown in fig. 10, which includes a gantry, and a magnetic resonance imaging system, a scanning bed 21, and a second sign detection device all mounted on the gantry.

The frame is a mounting carrier, and comprises a second platform 200 for mounting the scanning bed 21 and a shell 201 covered outside the magnetic resonance imaging system, wherein the shell 201 is made of environment-friendly materials so as to achieve attractive appearance and heat preservation.

As shown in fig. 10 and 11, the middle of the housing 201 is recessed to form a scanning cavity 202 for placing an infant for scanning, specifically, the scanning cavity 202 has a scanning position therein, at which the infant performs scanning. The second platform 200 is located at the bottom of the scanning chamber 202, which may be connected to the ground or other portion of the housing 201 by a bracket 203.

As shown in fig. 11 and 12, the scanner bed 21 is used for a baby to lie down, and includes a base 211 and a bed 212 connected to the base 211, and the base 211 is connected to the second platform 200. The bed 212 is provided with a binding belt fixing buckle 210 and a binding belt penetrating through the binding belt fixing buckle 210, so that the baby can be bound by the binding belt, the baby is prevented from moving, and the scanning is safer. The base 211 is movably connected with the second platform 200, and the base 211 can linearly move on the second platform 200, so that the scanning bed 21 can be moved to a scanning position of the magnetic resonance imaging system for scanning or moved out of the scanning position. The sliding connection mode between the two is not limited, and preferably, a second roller 2000 can be arranged on the second platform 200, two sides of the scanning bed 21 are limited by the shells 201 at two sides of the scanning cavity 202, and can move along the length direction of the scanning cavity 202; of course, a guide rail may be provided between the second stage 200 and the base 211.

The second stage 200 is capable of interfacing with the first stage 101 such that the incubator 11 can be moved from the first stage 101 to the second stage 200 and then to the scanning position for scanning. When the infant transfer apparatus 1 is moved into docking with the imaging apparatus 2, the first platform 101 and the second platform 200 are aligned such that the incubator 11 can be pushed from the first platform 101 onto the second platform 200.

As shown in fig. 10, in order to enable the infant transport apparatus 1 to conveniently dock with the imaging apparatus 2, the imaging apparatus 2 further includes a docking member 204 connected to the frame, and the docking member 204 is located outside the housing 201 and includes a base plate 2040 that is docked with the second platform 200, guide rollers 2041 provided on the base plate 2040, and two guide plates 2042 located on both sides of the base plate 2040. When docked, the base plate 2040 is flush with the guide plate 2042 or slightly below the guide plate 2042 so that the incubator 11 pushes up on the base plate 2040. The guide plate 2042 may be provided with a chamfer 2043 towards the inside of the end of the infant transfer apparatus 1 to form a flare to guide the incubator 11 into the docking member 204 and into the scanning chamber 202.

Further, referring to fig. 1 and 14, a vehicle body guide rail 3 for guiding the wheels 100 to move may be further disposed on the ground, which may better guide the infant transport apparatus 1 to dock with the imaging apparatus 2, thereby saving the positioning time for adjusting the infant transport apparatus 1 and improving the operation efficiency.

When it is desired to scan an infant in incubator 11, the scanner bed 21 may be pulled behind the second platform 200 to vacate the scan position and then the incubator 11 may be moved to the scan position for scanning. When scanning imaging of a conventional infant is desired, the infant may be placed on the scanner bed 21 and then pushed to the scanning position for scanning.

The second sign detection device is used for detecting the signs of the infant at the scanning bed 21, and can adopt a vital sign detection device special for magnetic resonance, and the probe is arranged at the scanning bed 21 for sign detection; the vital sign monitor can also be used for detecting infants by prolonging the filter special for vital sign detection into the scanning bed 21, and the use cost can be greatly reduced by using the conventional vital sign monitor because the vital sign detection device special for magnetic resonance is high in price.

The magnetic resonance imaging system is used for imaging infants, and is a mature technology in the prior art, so that the imaging can be realized by adopting the corresponding principle in the prior art, and after the scanning bed 21 or the incubator 11 is moved to the scanning position of the magnetic resonance imaging system, scanning imaging can be performed.

In this embodiment, the magnetic resonance imaging system includes a main magnet 230, gradient coils 232, and radio frequency devices.

As a preferred embodiment, the main magnet 230 is provided in a U-shaped open structure, as shown in fig. 13, which includes a magnet base 2300 and two oppositely disposed magnets 2301 connected to both sides of the magnet base 2300, the magnet base 2300 being installed under the second stage 200, and the magnets 2301 being located above the second stage 200 and on both sides of the scan cavity 202 to form a stable magnetic field. On the one hand, the main magnet 230 with the U-shaped open structure can effectively reduce the magnetic field escaping field, thereby being beneficial to improving the imaging quality, and on the other hand, the upper parts of the two magnets 2301 are not shielded, thereby being beneficial to taking and placing infants and being convenient for accompanying personnel to view the infants in real time.

Gradient coils 232 are positioned near the pole faces of the main magnet 230 in the scan volume 202 to generate a spatially linear magnetic field during imaging.

It will be appreciated that the two magnets 2301 form a scanning position therebetween, and that the length of the scanning chamber 202 is greater than the length of the scanning position to enable the scanning bed 21 to be moved out of the scanning position.

Further, in the present embodiment, there are two RF devices, as shown in FIG. 7 and FIG. 12, which are the first RF device 17 installed on the bed 112 and the second RF device 231 installed on the scanning bed 21, respectively, and since the infant in the NICU is usually smaller than the conventional infant, the first RF device 17 can be made smaller than the second RF device 231. The first rf device 17 and the second rf device 231 each include a portion located inside the bed 112 or the scanner bed 21 and a portion located outside thereof, the portion located outside being substantially semicircular in shape to form a space accommodating the scanning site.

The first rf device 17 and the second rf device 231 are preferably all integrated coils, and the integrated coils are designed to be compact and small, so that more space is available for installing the gradient coil 232, and the gradient coil 232 is far away from the pole face of the magnet and is closer to the B0 DSV region. By bringing the gradient coil 232 closer to the B0 DSV region, less current may be used to generate a particular gradient field strength. At the same time, the use of a smaller current means that a smaller lorentz force is generated, which will reduce the vibrations of the gradient coil 232, thereby reducing the impact on the mounting fixture impact, further reducing noise. The radio frequency power required for the 90 deg. flip angle radio frequency pulse can be made smaller as the coil is closer to the scanned area such as the head of the scanned person. When the coil is close to a scanning site such as the head of a scanned person, a more uniform emission of the B1 field can be achieved, which can reduce the deposition of radio frequency energy in so-called "hot spots" due to uneven emission excitation, thereby reducing low SAR values and improving the infant scanning safety.

Obviously, through setting up first radiofrequency device 17 on incubator 11 can make the baby directly scan the formation of image at incubator 11, need not to hold out to incubator 11 and scan the formation of image, more convenient and safe. Meanwhile, the imaging device 2 can be compatible with the infant transferring device 1 to scan and image infants in the incubator 11, and can also scan and image conventional infants, so that functions of the imaging device are more diversified, and the device is beneficial to fully utilizing the device.

As a preferred embodiment, the display control device 15 communicates with the control unit of the imaging device 2 to interact and transmit various parameters in real time, and if an abnormality is found, the display control device 15 will feed back and send out an alarm signal.

It will be appreciated that since the magnetic resonance system is sensitive to electromagnetic signals and has strong magnetic properties, the object entering the scan cavity 202 should be made of a non-magnetic material as much as possible, and for the electronic components, an electromagnetic shielding design may be used to reduce the influence on the magnetic field and ensure the reliability of its own operation. Preferably, the object located outside of the scan volume 202 is also made of a non-magnetic material as much as possible, for example, the carriage 10 may be made of a non-magnetic material.

After the scanning of the baby is finished, the sickbed body is pushed out, the binding belt is released, the baby is held away from the sickbed body, and the scanning is finished.

When scanning a critical infant (infant of NICU), it generally comprises the steps of 1. Before entering the NICU to transport the infant, the constant temperature is set by the display control device 15, after the temperature reaches the set value, the infant transport device 1 is pushed into the NICU, the infant is held in the incubator 11, the infant is connected to the heart rate blood oxygen probe, and if oxygen supply is needed, the oxygen supply device 13 is started. In the incubator 11, the part to be scanned of the infant is fixed at the scanning position of the first radio frequency device 17, the body of the infant is fixed by using the binding belt, and after the infant is fixed, the incubator cover is closed and locked. 2. After moving the infant transport apparatus 1 to the scanning room, the infant transport apparatus is first moved to connect with the imaging apparatus 2, then the scanner bed 21 is moved out of the scanning position, and the incubator 11 is moved to the scanning position for scanning. The display control means 15 is capable of displaying in real time the temperature inside the incubator 11, physiological monitoring sign data (body temperature, blood sample saturation, pulse) etc., while it is in real time data transmission and communication with the control unit of the imaging device 2. An alarm threshold value is set in the display control device 15, once the alarm threshold value is exceeded, audible and visual alarm is carried out outwards, and meanwhile, the control unit of the imaging equipment 2 can also send alarm information to remind operators to carry out emergency treatment, so that the life safety of infants is protected. 3. After the infant scanning is finished, the incubator 11 is pushed onto the infant transfer device 1, after the incubator 11 is fixed, the infant transfer device 1 is pushed back to the NICU, after the infant is reached to the NICU, the incubator 11 is opened, the infant restraint strap is loosened, the infant is held back to the original treated bed, and the operation is finished.
