Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically a chest fixation device for children. Background Technology

[0002] Chest X-rays are a common medical imaging examination for children. As a medical auxiliary device, they are used to observe the condition of the lungs, heart, ribs, and other structures within the chest cavity. They are an important tool for diagnosing respiratory diseases. During the examination, children may exhibit involuntary movements such as twisting, crying, or fussing due to fear, discomfort, or curiosity, thus requiring the use of a restraint device. However, existing restraint devices often require manual intervention. For example, medical staff may raise the patient's arms and use sandbags to compress the upper arms and abdomen to stabilize the body and immobilize it; or straps may be used to secure the limbs to the examination table; or one medical staff member may raise the patient's arms and hold their head while another manually compresses the structures below the chest to maintain a passive chest position. This can easily lead to resistance from the child due to the pressure of the restraint device, causing it to shift and lose its effectiveness.

[0003] To overcome the aforementioned deficiencies, existing technology (Chinese patent application number: 202120972258.3, application date: May 8, 2021) discloses a body fixation device for pediatric chest X-ray imaging, including a medical foam pad with a human-shaped groove, an arm fixation part, an abdominal fixation part, and a leg fixation part; the arm fixation part, abdominal fixation part, and leg fixation part are sequentially arranged above the arm, abdomen, and leg of the human-shaped groove on the medical foam pad. The grooved design of the foam pad regulates the patient's examination position and restricts the patient's movement space. The headrest design provides support for the patient's head and neck, solving the problem of the fixation device slipping off and causing injury around the patient due to resistance. The use of sandbags provides pressure, fixation, and radiation protection, achieving effective fixation of the body position, improving the success rate of chest X-ray examinations for infants and young children, improving image quality, and offering low material cost and easy operation.

[0004] Although existing technologies can restrain young children, the sandbags need to be placed and secured manually, which is time-consuming and prone to displacement, especially when the child struggles. In addition, the size of the human-shaped slot is fixed and it is difficult to adapt to different body types, resulting in poor restraint for young children. Therefore, the restraint device cannot meet the restraint needs of children of different body types.

[0005] Therefore, we proposed a chest fixation device for children that can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a child chest fixation device to solve the problems mentioned in the background art. When using the current fixation device, the sandbag needs to be manually placed and fixed, which is time-consuming and easy to shift, especially when the child struggles, it may fall off.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 The present invention provides the following technical solution:

[0027] Example 1: To address the problems of existing immobilization devices on the market, which require manual placement and securing of sandbags, are time-consuming and prone to displacement, especially when the child struggles, and may fall off, and whose fixed-size human-shaped grooves are difficult to adapt to different body types, resulting in poor immobilization for young children, this example discloses a pediatric chest immobilizer with the following technical details, which can be found in the attached document. Figure 1 -Appendix Figure 5 The system includes a chest X-ray CT stand 1, a base 2 fixedly mounted on the top of the chest X-ray CT stand 1, an anti-slip layer 3 fixedly connected to the top of the base 2, and grooves 4 symmetrically formed inside the anti-slip layer 3. A connecting plate 9 is fixedly mounted on the top of the anti-slip layer 3, and Velcro hook surfaces 10 are installed on the inner sides of the connecting plate 9. Mounting seats 5 are fixedly mounted on the top of the two sides of the anti-slip layer 3, and straps 6 are fixedly connected to the top of the mounting seats 5. Velcro loop surfaces 7 are fixedly connected to the top of the straps 6, and fixing bolts 8 are threaded inside the straps 6. A support base 11 is fixedly mounted on the top of the mounting seats 5, and a telescopic component for length adjustment is provided on the top of the support base 11. The telescopic component includes a support cylinder 12. The outer wall of the support cylinder 12 is provided with a mounting assembly for fixing; the mounting assembly includes a fixing ring plate 13, a protective pad 14 is fixedly installed on the inner wall of the fixing ring plate 13, a first hook and loop tape 15 is fixedly connected to the right side of the fixing ring plate 13, a second hook and loop tape 16 is fixedly connected to the left side of the fixing ring plate 13, and the second hook and loop tape 16 is pasted to the outer surface of the second hook and loop tape 16; the hook and loop surface 7 and the hook and loop hook surface 10 are pasted together, the hook and loop surface 7 and the binding strap 6 are tightly fitted together, and the binding strap 6 is made of soft cloth; the fixing ring plate 13 is fixedly connected to the support cylinder 12, and there are two support cylinders 12, and the fixing ring plate 13 is made of hard plastic.

[0028] Staff carefully place the child needing a chest examination onto the CT scanner seat 1, ensuring the child's feet are in contact with the anti-slip layer 3 and positioned within the symmetrically arranged grooves 4. These grooves provide foot positioning. Next, depending on the child's foot size, the straps 6 are manually wrapped around the instep, adjusting the Velcro loops 7 and hooks 10 to achieve the appropriate tightness for children of different sizes. The staff then rotates the retaining pin 8 inside the straps 6, inserting it into the connecting plate 9 to further reinforce the straps. The straps 6, made of soft fabric, conform well to the child's body without harming their skin, effectively securing the child's feet. After foot fixation is complete... The staff member places the child's back into contact with the protective pad 14 connected to the fixing ring plate 13. The protective pad 14 provides cushioning and protection, preventing the fixing ring plate 13 from directly contacting the child's back skin and causing discomfort or injury. Then, according to the child's body size, the staff member manually wraps the first Velcro strap 15 on the right side of the fixing ring plate 13 around the child's chest, and then wraps the second Velcro strap 16 on the left side around the child's chest, adjusts its position, and attaches it to the outer surface of the first Velcro strap 15, so that the fixing ring plate 13 can fit tightly against the child's chest, providing better support and fixation. Finally, the staff member raises the child's arm so that the child's hand is on the handrail 26, which helps the child maintain a relatively stable posture during the examination and reduces the impact of arm swaying on the examination results, so that the fixation device can adapt to the fixation needs of children of different body sizes.

[0029] Example 2: This example discloses a pediatric chest fixation device with the following technical features, facilitating height adjustment of the fixation device. Please refer to the attached document. Figure 1 Appendix Figure 4 and attached Figure 6 The support cylinder 12 has symmetrically arranged grooves 24 inside, and a sliding plate 25 is movably connected inside the grooves 24. A compression spring 17 is fixedly installed at the bottom of the sliding plate 25, and an extension rod 18 is fixedly connected to the top of the sliding plate 25. The top end of the extension rod 18 passes through the support cylinder 12, and several through holes are opened inside the extension rod 18. A handrail ring 26 is fixedly installed at the top left of the support cylinder 12. A fixed cylinder 19 is fixedly installed inside the fixed cylinder 19, and a movable plate 20 is movably connected inside the fixed cylinder 19. A locking rod 21 is fixedly installed on the right side of the movable plate 20, and the end of the locking rod 21 passes through a through hole. A pull rod 22 is fixedly connected to the left side of the movable plate 20, and a strong spring 23 is sleeved on the outer wall of the pull rod 22. The extension rod 18 is movably connected to the support cylinder 12, the extension rod 18 is tightly fitted to the sliding plate 25, and the sliding plate 25 is slidably connected to the grooves 24.

[0030] After the child's feet and back are secured to the restraints, the child's arms are raised. Based on the length of the child's raised arms, the staff pulls the lever 22 outwards sequentially. Lever 22 is connected to the moving plate 20. When lever 22 is pulled, it causes the moving plate 20 to move outwards within the corresponding fixed cylinder 19. During this movement, the moving plate 20 also causes the locking lever 21 to move outwards, retracting it into the fixed cylinder 19. Simultaneously, the moving plate 20 compresses the connected high-strength spring 23. The high-strength spring 23 undergoes elastic deformation due to compression, storing elastic potential energy. After the locking lever 21 retracts into the fixed cylinder 19, the staff manually pulls the extension rod 18 upwards, causing the extension rod 18 to move the slide plate 25 upwards within the slide groove 24. The extension rod 18 moves upward to a suitable position by sliding and simultaneously stretching the compression spring 17. Then, the staff releases the pulling rod 22. At this time, the elastic potential energy stored in the strong spring 23 begins to be released, generating a rebound force that drives the moving plate 20 to move. The locking rod 21 connected to the moving plate 20 also resets and is inserted into the corresponding through hole, thereby fixing the extension rod 18 inside the support cylinder 12. This allows for height adjustment of the fixture, ensuring that the child's arm is effectively supported and improving the fixture's adaptability to different children.
