Description

Technical Field

[0001] This utility model relates to the field of magnetic resonance imaging technology, specifically to a magnetic resonance coil device for examining the head and spine of an infant. Background Technology

[0002] Magnetic resonance imaging (MRI) is a medical application of the principles of magnetic resonance imaging. Compared with other auxiliary examination methods, MRI has advantages such as more imaging parameters, faster scanning speed, higher tissue resolution, and clearer images.

[0003] During an MRI scan, the patient needs to wear an external coil around the area being examined to perform the imaging. When performing an MRI on an infant's head, an infant head-spine coil is typically used. This coil usually consists of a base and a head cover. During the examination, the infant is placed flat on the base, and their head is inserted into the head cover. The coil inside the head cover then performs the imaging examination of the infant's head.

[0004] In the earliest infant head-spine coils, the base and head cover were an integrated structure, such as the infant whole-body radiofrequency coil device for magnetic resonance imaging systems disclosed in announcement number CN202196164U. This structure required an adult to hold the infant and insert their head into the head cover during the examination, which was time-consuming and prone to misplacement requiring repeated placement. Later, infant head-spine coils with openable head covers were developed, such as the magnetic resonance imaging system coil for infants disclosed in announcement number CN206460158U. In this coil, the upper head cover is fixedly connected to the lower head cover via buckles at both ends. During the examination, the upper head cover is opened by operating the buckles at both ends, and the infant is laid flat on the base with their head resting on the lower head cover before the examination.

[0005] It is evident that existing infant head-spine coils with openable head covers require medical staff to operate with both hands simultaneously to open the head cover, making single-handed operation impossible, which is inconvenient and affects examination efficiency. Utility Model Content

[0006] To address some or all of the problems existing in the prior art, this utility model provides a magnetic resonance coil device for examining an infant's head and spine, comprising a base and a head cover. The base is provided with a backrest for lying flat and a lower head cover for head support. The upper and lower head covers are connected and closed. Both the upper and lower head covers contain coil units. The upper head cover has a locking structure that is detachably connected to the lower head cover. The locking structure includes an unlocking button connected to the upper head cover, one end of which extends out of the outer wall of the upper head cover. The upper head cover contains a transmission assembly. The lower end face of the upper head cover has multiple locking tongues. The transmission assembly is connected to the unlocking button and the locking tongues respectively. The upper end face of the lower head cover has multiple engaging slots, each corresponding to a locking tongue. The unlocking button can drive the locking tongues to slide laterally within the upper head cover, thereby engaging or disengaging the locking tongues with the engaging slots.

[0007] As a further improvement of this utility model, the transmission component includes a linkage member and a sliding member. The linkage member is connected to the unlock button, the sliding member is slidably connected to the headgear cover, one end of the locking tongue is connected to the sliding member, the linkage member abuts against the sliding member, and can push the sliding member to slide laterally inside the headgear cover.

[0008] As a further improvement of this utility model, the linkage member is provided with a first inclined surface at one end near the sliding member, and the sliding member is provided with a second inclined surface. The first inclined surface abuts against the second inclined surface, and the first inclined surface can slide on the second inclined surface.

[0009] As a further improvement of this utility model, there are two sliding members, and the two sliding members are symmetrically distributed on the left and right sides along the center line of the head cover. Each sliding member is provided with at least one locking tongue.

[0010] As a further improvement of this utility model, the locking tongue and the sliding member are integrally formed.

[0011] As a further improvement of this utility model, a return spring is provided inside the head cover at a position corresponding to the sliding member. The two ends of the return spring are respectively connected to the head cover and the sliding member. The return spring is used to push the sliding member to move closer to the linkage member.

[0012] As a further improvement of this utility model, a positioning post is provided on the lower end surface of the head cover, and a positioning hole is provided on the upper end surface of the head cover, wherein the positioning post and the positioning hole are detachably inserted.

[0013] As a further improvement of this utility model, the upper cover of the headgear is provided with a limiting step surface, and the upper end of the lower cover of the headgear is provided with a guide boss, which can abut against the limiting step surface.

[0014] As a further improvement of this utility model, a handle is provided on the upper surface of the headgear cover, and the handle is located on one side of the unlock button.

[0015] As a further improvement of this utility model, the headgear cover is provided with a plurality of perforated holes in an array.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention allows for one-handed opening of the headgear cover by pressing an unlock button, improving operational convenience and thus increasing inspection efficiency. Normally, the headgear cover and lower headgear cover are closed together, with the locking tongue engaged with the corresponding snap-fit ​​groove. When an inspection is required, pressing the unlock button drives the transmission component, which in turn pushes the locking tongue to slide within the headgear cover, disengaging it from the snap-fit ​​groove. The headgear cover can then be lifted. The infant is then placed on the base, with their head resting against the lower headgear cover. The headgear cover is then replaced, locking the tongue in place with the corresponding snap-fit ​​groove. Magnetic resonance imaging (MRI) of the infant can then be performed via the coil unit.

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0023] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figure 1-3 As shown, a magnetic resonance imaging (MRI) coil device for examining an infant's head and spine includes a base 1 and a head cover 2. The base 1 has a backrest 11 for lying flat and a head cover 3 for head support. The head cover 2 and head cover 3 are shaped to fit together and are closed together. Both the head cover 2 and head cover 3 contain coil units. After the head cover 2 and head cover 3 are closed, a hemispherical cavity is formed inside, which can accommodate the infant's head. During the examination, the infant's head is completely covered, allowing the internal coil units to perform MRI imaging of the infant's head or spine.

[0026] The upper cover 2 of the head cover is provided with a locking structure, which is detachably connected to the lower cover 3 of the head cover. The locking structure makes it easy to separate the upper cover 2 of the head cover from the lower cover 3 of the head cover, so as to facilitate placing the baby on the base 1 and allowing the baby's head to rest on the lower cover 3 of the head cover.

[0027] Specifically, the locking structure includes an unlocking button 4, which is slidably connected to the headgear cover 2, with one end of the unlocking button 4 extending out of the outer wall of the headgear cover 2 for easy pressing by the user. The headgear cover 2 contains a transmission assembly, and its lower surface has multiple locking tongues 5. The transmission assembly is connected to the unlocking button 4 and the locking tongues 5 respectively. The upper surface of the headgear cover 3 has multiple engaging slots 31, each corresponding to a locking tongue 5. The unlocking button 4 can drive the locking tongues 5 to slide laterally within the headgear cover 2, thereby engaging or disengaging the locking tongues 5 from the engaging slots 31.

[0028] Normally, the upper head cover 2 and the lower head cover 3 are closed, and the locking tongue 5 is engaged with the corresponding locking slot 31. When the magnetic resonance coil device is needed to examine the infant, first press the unlock button 4. The unlock button 4 drives the transmission component to move, and the transmission component pushes the locking tongue 5 to slide laterally inside the upper head cover 2, thereby disengaging the locking tongue 5 from the locking slot 31. At this time, the upper head cover 2 can be removed from the lower head cover 3. Then, place the infant flat on the base 1, with the infant's back lying flat on the back support 11, and the infant's head resting against the lower head cover 3. Then, close the upper head cover 2 back onto the lower head cover 3 until the locking tongue 5 is engaged with the corresponding locking slot 31. After that, the infant can be examined by magnetic resonance imaging through the coil unit inside the upper head cover 2 and the lower head cover 3. The magnetic resonance coil device can open the upper cover 2 and the lower cover 3 of the headgear by simply pressing the unlock button 4 with one hand, which simplifies the operation, improves the convenience of operation, and thus improves the efficiency of inspection.

[0029] The transmission assembly includes a linkage 6 and a sliding member 7. The linkage 6 is fixedly connected to one end of the unlock button 4 that extends into the headgear cover 2. The sliding member 7 is slidably limited to the headgear cover 2. One end of the locking tongue 5 is fixedly connected to the sliding member 7. One end of the linkage 6 abuts against the sliding member 7 and can push the sliding member 7 to slide laterally within the headgear cover 2. During use, when the user presses the unlock button 4, the unlock button 4 will push the linkage 6 down, and the linkage 6 will push the sliding member 7 to slide laterally within the headgear cover 2. The sliding member 7 will then drive the locking tongue 5 to move synchronously, causing the locking tongue 5 to disengage from the locking groove 31, thereby unlocking the headgear cover 2 and the headgear cover 3.

[0030] Specifically, the linkage 6 has a first inclined surface 61 near the sliding component 7, and the sliding component 7 has a second inclined surface 71. The first inclined surface 61 abuts against the second inclined surface 71, and the first inclined surface 61 can slide on the second inclined surface 71. In use, when the unlocking button 4 drives the linkage 6 to descend, the first inclined surface 61 slides on the second inclined surface 71, and through the cooperation of the inclined surfaces, pushes the sliding component 7 to slide laterally inside the head cover 2, thereby achieving the purpose of driving the locking tongue 5 to slide laterally.

[0031] In this embodiment, each side of the unlock button 4 is provided with a linkage 6, and there are two sliding parts 7. The two sliding parts 7 are symmetrically distributed along the center line of the headgear cover 2. Each sliding part 7 abuts against a corresponding linkage 6, and each sliding part 7 is provided with two locking tongues 5. Pressing the unlock button 4 can simultaneously drive the two linkage parts 6 to descend, thereby pushing the sliding parts 7 on both sides of the headgear cover 2 to slide simultaneously, so that the four locking tongues 5 move synchronously, realizing unlocking. The locking tongues 5 are provided on both sides of the headgear cover 2, so that the headgear cover 2 and the headgear cover 3 form a multi-point engagement, which improves the stability of the connection between the headgear cover 2 and the headgear cover 3.

[0032] In other embodiments, the number of sliders 7, linkages 6, and locking tongues 5 can be any other number; it is sufficient to ensure that there is at least one locking tongue 5 on each of the left and right sides of the headgear cover 2.

[0033] In this embodiment, the locking tongue 5 and the sliding member 7 are integrally formed; in other embodiments, the locking tongue 5 and the sliding member 7 can also be two independent components, which can be fixed by screwing, snapping or other means.

[0034] A return spring 8 is provided inside the headgear cover 2 at a position corresponding to the sliding member 7. The two ends of the return spring 8 are connected to the headgear cover 2 and the sliding member 7, respectively. The return spring 8 is used to push the sliding member 7 to move closer to the linkage member 6. During use, when the headgear cover 2 is closed onto the headgear cover 3, the locking tongue 5 is first aligned with the locking groove 31. After the locking tongue 5 extends into the locking groove 31, the side wall of the locking groove 31 will squeeze the locking tongue 5, thereby pushing the locking tongue 5 and the sliding member 7 to slide inside the headgear cover 2. The sliding member 7 will compress the return spring 8. When the locking tongue 5 passes through the locking groove 31, under the elastic force of the return spring 8, it will push the sliding member 7 and the locking tongue 5 to move in opposite directions, thereby locking the locking tongue 5 into the locking groove 31 and locking the headgear cover 2 and the headgear cover 3 in place. On the other hand, during the pressing of the unlock button 4, the slider 7 will also compress the reset spring 8. After the unlock button 4 is released, the slider 7 will be pushed to slide laterally under the elastic force of the reset spring 8. The slider 7 pushes the linkage 6 to rise, so that the unlock button 4 rises and resets to the initial state.

[0035] To enable the upper cover 2 and lower cover 3 of the headgear to close quickly, a positioning post 21 is provided on the lower end face of the upper cover 2, and a positioning hole 32 is provided on the upper end face of the lower cover 3. The positioning post 21 and the positioning hole 32 are detachably connected. During installation, by aligning the positioning post 21 with the positioning hole 32 and inserting the positioning post 21 into the corresponding positioning hole 32, the upper cover 2 and lower cover 3 of the headgear can be quickly closed, improving the convenience of assembly and thus improving inspection efficiency.

[0036] On the other hand, a limiting step surface 22 is provided on the upper cover 2 of the headgear, and a guide boss 33 is provided at the upper end of the lower cover 3 of the headgear. After the upper cover 2 of the headgear is closed onto the lower cover 3 of the headgear, the guide boss 33 abuts against the limiting step surface 22. With the cooperation of the guide boss 33 and the limiting step surface 22, the stroke and position of the upper cover 2 of the headgear closing onto the lower cover 3 of the headgear can be limited, so that the upper cover 2 of the headgear can be aligned with the lower cover 3 of the headgear more quickly, improving the assembly efficiency and thus further improving the inspection efficiency.

[0037] To facilitate the removal of the upper cover 2 from the lower cover 3, a handle 23 is provided on the upper surface of the upper cover 2, and the handle 23 is located to the side of the unlock button 4. After the upper cover 2 is unlocked from the lower cover 3, the user can remove the upper cover 2 from the lower cover 3 by holding the handle 23; and the fact that the handle 23 is located to the side of the unlock button 4 allows the user to simultaneously unlock the upper cover 2 and remove the upper cover 2 from the lower cover 3 with one hand, further improving the convenience of operation.

[0038] In this embodiment, multiple perforated holes 24 are arranged in an array on the head cover 2. By setting the perforated holes 24, the infant can also observe the external environment during the examination, avoiding the fear and discomfort caused by the confined space and improving the comfort of the infant during the examination.

[0039] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
