Description

Technical Field

[0001] This application relates to the field of medical devices, specifically to a positioning device for pediatric cardiopulmonary resuscitation. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) is an important emergency measure for treating patients with cardiac arrest, and correct positioning and head immobilization are crucial for the effectiveness of resuscitation. Infants and young children have a prominent occipital protuberance on their heads, and due to the lack of targeted support design in related techniques, medical staff or rescuers often have to use temporary alternatives, such as using readily available pillows, towels, or other items to place under their heads.

[0003] However, the materials used for temporary head supports are often irregularly shaped and cannot conform to the contours of an infant's head, especially the occipital protuberance area. They are prone to displacement during resuscitation procedures, leading to head instability. Summary of the Invention

[0004] This application provides a positioning device for pediatric cardiopulmonary resuscitation, which can solve the technical problem that the temporary elevating material used during cardiopulmonary resuscitation is usually irregular in shape and cannot fit the contour of the infant's head, especially the occipital protuberance area, and is prone to displacement during resuscitation, resulting in unstable head position.

[0005] In a first aspect, embodiments of this application provide a positioning device for pediatric cardiopulmonary resuscitation, comprising: a shoulder support; an annular support pillow connected to the shoulder support, the annular support pillow having a bulge placement groove surrounding it, and the annular support pillow having a notch communicating with the bulge placement groove on the side near the shoulder support pillow; the annular support pillow being connected to a size adjustment mechanism for tightening the annular support pillow to adjust the size of the bulge placement groove. In conjunction with the first aspect, in one embodiment, the size adjustment mechanism includes: a BOA knob, the BOA knob being mounted on the annular support pillow; and a strap, the strap being wrapped around the periphery of the annular support pillow, with both ends of the strap connected to the BOA knob, the BOA knob being used to rotate and wrap around the strap to tighten the annular support pillow.

[0006] In conjunction with the first aspect, in one embodiment, the annular support pillow includes a first arc-shaped side and a second arc-shaped side arranged circumferentially along the annular support pillow, the first arc-shaped side and the second arc-shaped side being arranged radially spaced along the protrusion placement groove; a plurality of first guide members are installed on the first arc-shaped side, the plurality of first guide members being spaced apart along the length direction of the first arc-shaped side, and a plurality of second guide members are installed on the second arc-shaped side, the plurality of second guide members being spaced apart along the length direction of the second arc-shaped side; the straps alternately pass through the first guide members and the second guide members along a preset path, forming an alternating inner and outer binding structure.

[0007] In conjunction with the first aspect, in one embodiment, the thickness of the shoulder support member on the side closer to the annular support pillow is greater than the thickness of the shoulder support member on the side farther from the annular support pillow.

[0008] In conjunction with the first aspect, in one embodiment, the shoulder support and the annular support pillow are connected by a connector, the thickness of which is less than the thickness of the shoulder support near the annular support pillow. In conjunction with the first aspect, in one embodiment, the shoulder support member has an arc-shaped chamfer on the side away from the annular support pillow.

[0009] In conjunction with the first aspect, in one embodiment, both the shoulder support and the bottom surface of the annular support pillow are connected to anti-slip silicone pads.

[0010] In conjunction with the first aspect, in one embodiment, the shoulder support is made of memory foam material.

[0011] The beneficial effects of the technical solutions provided in this application include: A ring-shaped support pillow can support the infant's head. The notch in the ring allows the infant's neck to pass through, placing the infant's lenticule in the lenticule placement slot. This method not only supports the infant's head but also enhances head stability. Furthermore, the size adjustment mechanism can adjust the size of the lenticule placement slot to accommodate infants with different head sizes. Further, a shoulder support component elevates the infant's shoulders to a certain height, better meeting the needs of airway opening. This solves the technical problem that temporary elevators used in lung resuscitation in related technical centers are often irregularly shaped, unable to conform to the infant's head contour, and prone to displacement during resuscitation, leading to head instability.

[0015] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0016] This application provides a positioning device for pediatric cardiopulmonary resuscitation, which solves the technical problem that temporary elevating objects used during cardiopulmonary resuscitation are usually made of irregularly shaped materials, which cannot conform to the contour of an infant's head, especially the occipital protuberance area, and are prone to displacement during resuscitation, resulting in unstable head position.

[0017] See Figure 1The image shows a positioning device for pediatric cardiopulmonary resuscitation provided in this application embodiment. It may include: a shoulder support 1; and a ring-shaped support pillow 2 connected to the shoulder support 1. The ring-shaped support pillow 2 has a pylorus placement groove 21 surrounding it, and has a notch 22 on the side near the shoulder support pillow that communicates with the pylorus placement groove 21. The ring-shaped support pillow 2 is connected to a size adjustment mechanism 3, which is used to tighten the ring-shaped support pillow 2 to adjust the size of the pylorus placement groove 21. In this embodiment, the shoulder support 1 and the ring-shaped support pillow 2 can be detachably connected. Depending on the specific situation of different infants, it can be determined whether the shoulder support 1 is needed to elevate the infant's shoulders to better open the airway. In some other embodiments, the shoulder support 1 and the ring-shaped support pillow 2 can also be fixedly connected to reduce the adjustment process. Specifically, the size adjustment mechanism 3 can adjust the size of the pylorus placement groove 21 by making the pylorus placement groove 21 larger when the size adjustment mechanism 3 tightens the ring-shaped support pillow 2.

[0018] In this embodiment, the ring-shaped support pillow 2 can support the head of an infant. The notch 22 of the ring-shaped support pillow 2 allows the infant's neck to pass through, so that the infant's bulge is placed in the bulge placement groove 21, as if the infant's head is "embedded" into the bulge placement groove 21. This method can support the infant's head and enhance the stability of the head placement. In addition, the size adjustment mechanism 3 can adjust the size of the bulge placement groove 21 to accommodate infants with different head sizes. After the infant's head is placed in the bulge placement groove 21 of a suitable size, the side walls of the ring-shaped support pillow 2 can restrain the infant's head from turning to the left or right. Furthermore, by using the shoulder support 1 to raise the infant's shoulders to a certain height, it can better meet the needs of airway opening. The shoulder support 1 can fit the infant's shoulders and upper chest, and generate friction through contact with the torso to restrict the movement of the upper body. This solves the technical problem that the temporary elevating material used in lung resuscitation in related technical centers is usually irregular in shape and cannot conform to the contour of the infant's head, making it easy to shift during resuscitation operations and causing unstable head position.

[0019] See Figure 3 and Figure 4As shown, in some optional embodiments, the size adjustment mechanism 3 includes: a BOA knob 31, which is mounted on the annular support pillow 2; and a strap 32, which is wrapped around the periphery of the annular support pillow 2, with both ends of the strap 32 connected to the BOA knob 31. The BOA knob 31 is used to rotate and wrap around the strap 32 to tighten the annular support pillow 2. It should be understood that the BOA knob 31 can refer to a quick-tightening system commonly used in footwear or sports equipment in related technologies, which can work with the strap 32 to quickly tighten and loosen. In this embodiment, the strap 32 is wrapped around the outer surface of the annular support pillow 2, with both ends of the strap 32 passing through the BOA knob 31. When it is necessary to enlarge the protuberance placement groove 21, the knob is rotated directly in the set direction. During rotation, the strap 32 is locked, and the wrapped portion of the annular support pillow 2 tightens simultaneously, increasing the size of the protuberance placement groove 21. When it is necessary to restore the size of the protuberance placement groove 21 to the size when the annular support pillow 2 is not tightened, the knob is pressed. At this time, the knob will pop up or unlock, the strap 32 will automatically loosen, and the annular support pillow 2 will return to a relaxed state. It should be understood that when the annular support pillow 2 is in a relaxed state, the protuberance placement groove 21 has its minimum size, and the required adjustment size of the protuberance placement groove 21 is closely related to the tightness of the annular support pillow 2. Furthermore, to better achieve the effect of adjusting the size of the protuberance placement groove 21, the strap 32 wrapped around the annular support pillow 2 can be relatively dense. This method can quickly achieve the adjustment of the size of the protuberance placement groove 21, enhancing the ease of use of the body positioning fixation device.

[0020] In some optional embodiments, the annular support pillow 2 may include a first arc-shaped side 23 and a second arc-shaped side 24 arranged circumferentially along the annular support pillow 2, the first arc-shaped side 23 and the second arc-shaped side 24 being arranged radially spaced along the protrusion placement groove 21; the first arc-shaped side 23 is equipped with a plurality of first guide members 33, the plurality of first guide members 33 being spaced apart along the length direction of the first arc-shaped side 23; and the second arc-shaped side 24 is equipped with a plurality of second guide members 34, the plurality of second guide members 34 being spaced apart along the length direction of the second arc-shaped side 24; the strap 32 is alternately threaded through the first guide members 33 and the second guide members 34 along a preset path, forming an alternating inner and outer binding structure. Specifically, the first arc-shaped side 23 and the second arc-shaped side 24 together form the sidewall foundation of the protrusion placement groove 21. Multiple first guide members 33 and second guide members 34 are respectively installed on the first arc-shaped side 23 and the second arc-shaped side 24 to facilitate the passage of the strap 32 and effectively prevent the strap 32 from shifting position on the annular support pillow 2 during the tightening process. See also... Figure 4As shown, the strap 32 passes sequentially through the first guide member 33 and the second guide member 34 along a preset path at different angles. The strap 32 then passes through a, b, c, d… until its end is threaded through the BOA button 31, forming an alternating inner and outer binding structure. The strap 32 wraps from the front of the annular support pillow 2 to the back, and then back again, binding in an alternating pattern. It should be understood that the inner side refers to the side of the annular support pillow 2 closest to the protrusion placement groove 21, and the outer side refers to the side of the annular support pillow 2 away from the protrusion placement groove 21. The front of the annular support pillow 2 refers to the side that supports the infant's head, and the back refers to the side placed on the bed or floor. In this embodiment, the alternating inner and outer binding structure formed by the strap 32 can tighten the annular support pillow 2 as evenly as possible, making the size adjustment of the protrusion placement groove 21 more precise, conforming to different infants' heads, and enhancing support stability. In some other embodiments, the strap 32 can also be set up like shoelaces with a crisscross binding, but both ends must pass through the BOA button 31.

[0021] In some optional embodiments, the thickness of the shoulder support 1 on the side closer to the annular support pillow 2 is greater than the thickness of the shoulder support 1 on the side farther from the annular support pillow 2. In this embodiment, the thickness of the shoulder support 1 varies uniformly from the side farther from the annular support pillow 2 to the side closer to the annular support pillow 2, and the shoulder support 1 on the side closer to the annular support pillow 2 is thicker, which can naturally form an inclined support surface towards the annular support pillow 2. The inclination angle of the inclined support surface can be set from 15° to 30°. This structure allows the infant's shoulders to be moderately raised, which, together with the position of the head in the annular support pillow 2, helps maintain the head tilt angle required for airway opening. At the same time, the gradually varying thickness disperses shoulder pressure, improving support stability and comfort.

[0022] In some optional embodiments, the shoulder support 1 and the annular support pillow 2 are connected by a connector 4, the thickness of which is less than the thickness of the shoulder support 1 on the side closest to the annular support pillow 2. It should be understood that the thinner thickness of the connector 4 than the thickness of the shoulder support 1 on the side closest to the annular support pillow 2 avoids creating an abrupt step at the connection point. This arrangement ensures a stable connection between the shoulder support 1 and the annular support pillow 2, while also allowing for a smooth transition under the infant's neck, preventing neck pressure or congestion, improving postural comfort and safety, and without interfering with the airway opening angle.

[0023] In some optional embodiments, the shoulder support 1 has a rounded chamfer 11 on the side away from the annular support pillow 2. By setting the rounded chamfer 11, the sharp edges of the shoulder support 1 can be eliminated, avoiding injury or pressure to the infant's back and shoulders when in contact with the shoulder support 1, thus improving safety and comfort. In addition, the smooth transition of the rounded design can reduce the frictional resistance between the shoulder support 1 and clothing, sheets, etc., making it easier to quickly place or adjust the child's position.

[0024] See Figure 2 As shown, in some optional embodiments, the bottom surfaces of the shoulder support 1 and the annular support pillow 2 are both connected to anti-slip silicone pads. In this embodiment, the bottom of the connector 4 can also be connected to an anti-slip silicone pad. The anti-slip silicone pads on the bottom surfaces of the shoulder support 1, connector 4, and annular support pillow 2 are intended to increase the friction between the device and the placement surface. During cardiopulmonary resuscitation, the impact force of chest compressions can easily cause the device to slide as a whole. The anti-slip silicone pads can effectively prevent the device from shifting by increasing the frictional resistance of the contact surface, ensuring that the head and shoulders remain in a stable and fixed position.

[0025] Preferably, the shoulder support 1 is made of memory foam. Optionally, the ring-shaped support pillow 2 can also be made of memory foam. Memory foam has slow rebound properties, allowing it to automatically mold to the contours and pressure of the infant's shoulders, closely conforming to the shoulder curve. This evenly distributes shoulder pressure across the support surface, preventing poor blood circulation caused by localized pressure and reducing pressure marks or discomfort. Furthermore, memory foam provides support, and the shoulder support 1, with its own thickness design, stably maintains the required elevation angle of the infant's shoulders, ensuring the airway remains open and the body position doesn't shift. The ring-shaped support pillow 2 maintains a certain shape when the infant's head is placed on it.
