Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary technology, specifically to a device for assisting pediatric magnetic resonance imaging (MRI) examinations under anesthesia. Background Technology

[0002] Magnetic resonance imaging (MRI) plays an irreplaceable role in the diagnosis of pediatric diseases. Through MRI, doctors can non-invasively observe the fine structures of a child's brain, spine, and other organs, accurately determining whether there are malformations or developmental delays. This allows for the timely detection and intervention of congenital diseases, preventing their progression. MRI does not use ionizing radiation, making it safer than X-rays or CT scans, which is especially important for children whose bodies are still developing. During an MRI scan, the patient's head is typically placed inside a cranial coil. This coil emits radiofrequency signals to excite the hydrogen nuclei in the head, generating magnetic resonance, and receives the magnetic resonance signals produced by these hydrogen atoms. This process also reduces external interference, improves image quality, and can be used to perform special examinations to obtain information about the structure and physiology of head tissues for imaging and diagnosis.

[0003] However, in practice, children are naturally active and restless during MRI examinations, making it difficult for them to remain still for extended periods. This can lead to motion artifacts in the images, severely impacting image quality and diagnostic accuracy. Furthermore, younger children may experience anxiety and fear when entering the MRI machine due to the confined space and noise, exhibiting uncooperative behavior or even crying. This not only hinders the smooth progress of the examination but may also result in inaccurate results. To address these issues, anesthesia or sedation is commonly used in clinical practice to assist children during MRI examinations. However, this process also brings new challenges. Under anesthesia or sedation, the patient's muscle tone decreases, and the tongue and surrounding soft tissues are prone to fall backward, leading to airway obstruction and threatening the patient's life. During transport, since the patient cannot enter the MRI room on their own and the transport bed is prohibited from entering, family members usually have to carry them in, which poses a risk of falling. When wearing headphones or sound-absorbing foam, the difference in head circumference between children and the cranial coil can cause differences in noise reduction effect and comfort. During the examination, intravenous drip, ECG monitoring, oxygen inhalation, and other tubing can easily fall off or get stuck when the MRI examination bed moves in and out. The MRI bed surface is relatively hard, which is not comfortable for children when lying flat and is also not conducive to the accuracy of spinal scans. Utility Model Content

[0004] To address the aforementioned problems, this invention aims to provide a device for MRI examinations under anesthesia in children, which can improve the safety, accuracy, and comfort of MRI scans in children.

[0005] The main idea of ​​the technical solution adopted in this utility model is as follows: By using a split mattress, the upper layer is made of elastic and soft material to conform to the child's body and improve comfort, while the lower layer is made of hard material to provide stable support and ensure the child's body stability during the examination, avoiding body movement due to bed discomfort that may affect imaging; by setting up a first airbag and a second airbag to elevate the patient's chin, the patient's tongue and surrounding soft tissues are prevented from easily falling back, which could lead to airway obstruction and threaten life safety; by setting up a handle, a third airbag, and Velcro rings, the safety, accuracy, and comfort of pediatric MRI scans are further improved.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A device for MRI examination under anesthesia in children includes a split mattress, which is divided into a headrest area for supporting the head and a main support area for supporting the body, both of which are composed of an upper pad and a lower pad connected to each other; a head adjustment component is located above the headrest area to adjust the patient's head to a tilted-back and chin-raised position.

[0008] Further, based on the above technical solution: the head adjustment component includes a first airbag, positioned above the headrest area, composed of multiple interconnected bulbs, the bulbs of the first airbag being arranged in a honeycomb pattern with the size of the bulbs increasing sequentially from the front row to the back row; a second airbag, arc-shaped, symmetrically connected at both ends to the second airbag, composed of multiple interconnected bulbs, the bulbs of the second airbag being of the same size; and a third airbag, spherical, symmetrically positioned on both sides of the first airbag.

[0009] Furthermore, through the above technical solution: the first airbag is interconnected with the second and third airbags respectively, and the front end of the first airbag is provided with an airbag inflation / deflation port.

[0010] Furthermore, through the above technical solution, the upper padding layer is made of an elastic, soft material, and the lower padding layer is made of a rigid material.

[0011] Furthermore, the lower pad layer is provided with at least two handles on both sides.

[0012] Furthermore, based on the above technical solution, the split mattress surface is provided with several Velcro loops near the foot of the bed and on both sides.

[0013] Furthermore, the upper padding layer is provided with at least one pair of fixing straps and is respectively connected to both sides of the upper padding layer, and each pair of fixing straps includes a left fixing strap and a right fixing strap.

[0014] The beneficial effects of this utility model are:

[0015] 1. Improved examination safety: The head adjustment component adjusts the inflation volume of the airbag to allow the patient to tilt their head back and lift their chin, which can help maintain airway patency to a certain extent and prevent the tongue and surrounding soft tissues from falling back and obstructing the airway under anesthesia, thus ensuring the respiratory safety of children during the examination. The handles on both sides of the lower pad facilitate transportation and greatly reduce the risk of children falling during transportation under anesthesia, allowing family members and medical staff to send children into the MRI room more safely and efficiently.

[0016] 2. Improved Examination Comfort: The upper layer of the split mattress is made of elastic and soft material that conforms to the curves of a child's body, avoiding the discomfort caused by a hard mattress during MRI examinations. This makes children more comfortable under anesthesia. The lower layer, made of firm material, provides stable support, preventing body movement from affecting imaging and also effectively fixing the spinal cord, improving the accuracy of spinal scans. This ensures that the child's body is in a stable and comfortable state during the examination. Noise-canceling headphones can be hung directly on the mattress hooks for easy access and can be adjusted to fit the child's ear contours, improving wearing comfort and sealing, and effectively isolating noise during MRI examinations.

[0017] 3. Improve examination accuracy: The fixation strap can fix the child's body in a proper position, avoiding motion artifacts caused by body movement; the head adjustment component can keep the child's head stable while tilting their head back and raising their chin, reducing the impact of head movement on imaging, thereby improving image clarity and accuracy, and providing doctors with high-quality imaging data for accurate diagnosis.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] The inventors discovered that children are naturally active and restless during MRI examinations, making it difficult for them to remain still for extended periods. Therefore, anesthesia or sedation is used to assist with MRI scans. However, under anesthesia or sedation, decreased muscle tone and the tongue and surrounding soft tissues are prone to posterior displacement, potentially obstructing the airway and threatening the patient's life. During transport, patients cannot enter the MRI room independently, and the transport bed is prohibited from entering, usually requiring a family member to carry them, posing a risk of falls. When wearing headphones or sound-absorbing foam, differences in head circumference can create distance between the headphones and the cranial coil, resulting in varying noise reduction effects and comfort levels. During the examination, intravenous drips, ECG monitoring, and oxygen supply lines are prone to detachment or jamming when the MRI bed moves in and out. The relatively hard MRI bed surface is uncomfortable for children lying flat and also affects the accuracy of spinal scans.

[0027] Based on the above findings, this application proposes a device for MRI examinations under anesthesia in children, which improves the safety, accuracy, and comfort of MRI scans in children by incorporating a split mattress, head adjustment component, handle, Velcro loop, and fixation strap. Example

[0028] See Figures 1-6 This application discloses a device for assisted MRI examination under anesthesia in children, including a split mattress 1, referenced... Figures 1-3The split mattress 1 is divided into a headrest area 107 for supporting the head and a main support area 108 for supporting the body. The width of the headrest area 107 is smaller than the width of the main support area 108. The main support area 108 is used to support the patient's shoulders and below. During an MRI scan, the headrest area 107 where the patient's head is located needs to be placed in a cranial coil. The cranial coil has different styles, such as orthogonal head coils, phased array coils, H coils, figure-eight coils, etc. The cranial coil is existing technology and will not be described in detail here.

[0029] Furthermore, the split mattress 1 consists of an upper layer 101 and a lower layer 102 connected to each other. The upper layer 101 is 3-4 cm thick, and the lower layer 102 is 1-2 cm thick. A total mattress thickness of 4-6 cm is considered suitable. The upper layer 101 is made of a soft, elastic material, such as memory foam or high-density foam, which conforms to the curves of a child's body, avoiding the discomfort caused by a hard surface during MRI examinations, making the child more comfortable under anesthesia. The lower layer 102 is made of a firm material, such as carbon fiber composite material or engineering plastics, providing stable support for the body, preventing body movement from affecting imaging, and effectively fixing the spinal cord, improving the accuracy of spinal scans, and ensuring the child is in a stable and comfortable state during the examination.

[0030] Next, refer to Figures 4-6 The headrest area 107 is provided with a head adjustment component 2, which includes a first airbag 201, a second airbag 202 and a third airbag 204, used to adjust the patient's head to a head-tilt and chin-raised position.

[0031] Specifically, both the first airbag 201 and the second airbag 202 are made of rubber. The first airbag 201 is rectangular, matching the shape of the headrest area 107, and its bottom is tightly bonded to the headrest area 107. It consists of multiple interconnected bulbs 203, which are arranged in a honeycomb pattern. The size of the bulbs 203 increases from the front row to the back row (in this embodiment, the direction from the headrest area to the main support area is from front to back). Figure 6 As shown, when inflated, the cross-section of the first airbag 201 is an inverted triangle, so that when the child's head rests on the first airbag 201, it is tilted backward.

[0032] Furthermore, a second airbag 202 is connected to the first airbag 201. The second airbag 202 is arc-shaped, conforming to the physiological curve of the human jaw and neck. Both ends of the arc are heat-sealed to the sides of the first airbag 201. The second airbag 202 is also composed of multiple interconnected balloons 203. The balloons 203 of the second airbag 202 are of the same size and are used to elevate the child's jaw. Each balloon 203 has interconnected ventilation holes, and the first airbag 201 and the second airbag 202 are interconnected.

[0033] Furthermore, a third airbag 204 is symmetrically arranged on both sides of the first airbag 201. The third airbag 204 is spherical, and the first airbag 201 and the third airbag 204 are interconnected. The third airbag 204 is located in the ear area of ​​the patient and is used to fill the gap between the ear area and the head coil after the patient wears the headphones. This accommodates the differences in head circumference among children, effectively isolates noise during MRI examination, and stabilizes the patient's ear environment. At the same time, it can also prevent the headphones from shifting due to gaps during the examination, which could affect the sound insulation effect or cause ear discomfort to the patient.

[0034] The first airbag 201 has an airbag inflation / deflation port 2011 at its front end. This port 2011 is connected to an external inflation device for inflating, deflating, and adjusting the pressure of the first airbag 201, the second airbag 202, and the third airbag 204, thereby adjusting the airbag thickness for different patients. It is worth noting that the pressure of the first airbag 201 and the second airbag 202 is sufficient to support the child's head and elevate the child's chin to tilt their head back. During use, the child's head rests on the first airbag 201, and the second airbag 202 is placed under the child's chin. As inflation begins through the air inlet 2011 at the front of the first airbag 201, the second airbag 202 gradually expands, raising the child's chin. The side of the first airbag 201 closest to the child's neck is thicker, while the side further away is thinner, tilting the patient's head backward. This prevents the child's head from tilting back and chin from falling back under anesthesia or sedation, which could lead to airway obstruction and threaten the patient's life. Simultaneously, the third airbag fills the gap between the patient's ear and the cranial coil, stabilizing the ear environment.

[0035] Next, refer to Figures 2-3The lower mattress 102 has at least two handles 103 on both sides to facilitate the movement of the mattress by family members or medical staff while the child is under anesthesia. In this embodiment, two handles 103 are provided on each side. The handles 103 can be soft handles made of cotton or hard handles. If they are hard handles, they can be provided with anti-slip textures to facilitate the movement of the mattress by medical staff. The surface of the split mattress 1 has several Velcro loops 104 near the foot of the bed and on both sides. When the MRI examination bed is moved in and out, the tubing for maintaining anesthesia through intravenous drip, connecting the ECG monitoring tubing, and keeping the oxygen inhalation tubing, etc., are all secured by the Velcro loops 104 to prevent the risk of tubing falling off or getting stuck. The upper padding layer 101 is provided with at least one pair of fixing straps and is respectively connected to both sides of the upper padding layer 101. Each pair of fixing straps includes a left fixing strap 105 and a right fixing strap 106. The fixing straps are provided with sliding buckles to adjust the tightness of the fixing straps, ensuring that the fixing straps can fit tightly against the child's body, preventing the child from moving unconsciously during the MRI examination under anesthesia, and ensuring safety and accuracy of the examination.

[0036] Application Examples:

[0037] When a child undergoes an MRI scan, the anesthesiologist first assesses the child, inserts an indwelling needle and administers medication, places the device described in this application on a transport bed, and has the anesthetized child lie on the split mattress 1. The child's head is placed on the first airbag 201 of the headrest area 107, the second airbag 202 is placed on the child's chin, and the second airbag 202 is located at the child's ear. Various tubing is fixed to the split mattress 1 with Velcro loops 104. The left fixation strap 105 and the right fixation strap 106 are wrapped around the child's body, and the tightness of the fixation straps is adjusted by sliding buckles to make them fit the child's body tightly. Then, the child is transported to the entrance of the MRI room via a transfer bed. Using the handle 103, the child is transferred to the examination bed. Noise-canceling headphones are put on the child, and the headrest area 107 where the child's head is located is placed in the cranial coil. Then, the external inflation device is connected to the airbag inflation / deflation port 2011, and the first airbag 201, the second airbag 202, and the third airbag 204 are inflated, so that the child's head is tilted back and the chin is raised. The third airbag 204 fills the gap between the headphones and the cranial coil. The MRI equipment is then started to perform a scan.
