Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a child care restraint device. Background Technology

[0002] When children undergo X-ray examinations, they may become uncooperative due to factors such as sensitivity or panic, and may find it difficult to remain still for even a short period of time during the examination.

[0003] Chinese patent CN107184228B discloses a body restraint device for X-ray imaging of children, which is functionally divided into four sub-assemblies: a fixed base and a fixed clamping plate forming a fixed clamping assembly; a movable base, a movable clamping plate, and a track forming a movable clamping assembly; a pneumatic shell, a pneumatic column, a motor, and an impeller forming a drive assembly; and a valve shell, a spring, and a baffle forming an exhaust assembly. The fixed clamping assembly is restrained on the ground in front of the X-ray machine, and the movable clamping assembly slides on the ground in front of the X-ray machine, with the child clamped between the fixed clamping assembly and the movable clamping assembly. The drive assembly is connected to the movable clamping assembly, providing push and pull forces to the movable clamping assembly. The exhaust assembly is installed on the pneumatic shell of the drive assembly, limiting the pressure of the movable clamping assembly on the child's body. However, this device still has the following technical problems: 1. The structure of this limiting device is relatively complex, which not only results in high cost but also makes it difficult to maintain, thus hindering its widespread promotion and use; 2. This device clamps and secures the child by opening and closing a movable clamping plate, requiring a relatively large operating space.

[0004] Based on this, the present invention designs a child care restraint device to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a child care restraint device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A child care restraint device includes a frame; A rotating platform is rotatably mounted on the top of the frame, and an angle positioning component for controlling the angle of the rotating platform is installed between the frame and the rotating platform. A base is fixedly mounted on the bottom of the rotating platform. The rotating platform is equipped with a movable restraint mechanism, which includes a torso restraint mechanism and an upper limb restraint mechanism. The two torso restraint mechanisms are symmetrically installed on the rotating platform, and an upper limb restraint mechanism is installed on the side of each torso restraint mechanism. The trunk restraint mechanism includes a mounting base, a support base plate, a main clamping plate, a translational rotation assembly, and a closing self-locking assembly. The translational rotation assembly is mounted on a rotating platform, and the mounting base is mounted on the moving end of the translational rotation assembly. The top of the mounting base is engaged with the bottom of the main clamping plate, and the bottom of the mounting base is fixedly connected to the top of the support base plate. The bottom surface of the support base plate slides against the top surface of the rotating platform. The mounting base is also equipped with a closing self-locking assembly, which automatically locks the main clamping plates in the two trunk restraint mechanisms after closing to restrain the child's trunk.

[0007] Furthermore, the translation and rotation assembly includes a limiting groove, a limiting slider, and a rotating rod. A limiting groove is provided on the rotating platform, the limiting slider is slidably connected to the limiting groove, the bottom of the rotating rod is fixedly connected to the top of the limiting slider, and the top of the rotating rod is rotatably connected to the mounting base.

[0008] Furthermore, the closing self-locking assembly includes a front ratchet assembly and a rear ratchet assembly. The front ratchet assembly is mounted on the rotary table and located between the limiting slider and the frame. The rear ratchet assembly is mounted between the rear sides of the mounting seats in the two torso restraint mechanisms. The front ratchet assembly and the rear ratchet assembly are used to enable the mounting seats in the two torso restraint mechanisms to move only towards each other.

[0009] Furthermore, the upper limb restraint mechanism includes an adjustable arm restraint assembly and a hand restraint assembly. The bottom of the adjustable arm restraint assembly is connected to the top of the support base plate, and the top of the adjustable arm restraint assembly is connected to the hand restraint assembly.

[0010] Furthermore, the adjustable arm restraint assembly includes a support rod, a secondary clamping plate, and an angle adjustment assembly. The bottom of the support rod is hinged to the top of the support base plate. Multiple locking blocks that engage with the support rod are fixedly installed at equal intervals along the length of the secondary clamping plate. An angle adjustment assembly is installed between the support rod and the support base plate.

[0011] Furthermore, the hand restraint assembly includes an L-shaped handle, a grip, and finger sleeves. One end of the L-shaped handle is telescopically mounted inside the top of the support rod, and the grip is fixedly connected to the other end of the L-shaped handle. Multiple finger sleeves are fixedly mounted on the grip.

[0012] Furthermore, an extension rod is rotatably installed inside the L handle. The end of the finger sleeve passes through the grip and the L handle, wraps around the extension rod, and is fixedly connected to the extension rod. By rotating the extension rod, the finger sleeve can be tightened or extended, so that the finger sleeve can meet the restraint effect for fingers of different sizes. The outer side of the adjusting inner rod is also threaded with a fastening bolt for fixing the extension rod relative to the L handle.

[0013] Furthermore, the main and auxiliary plates can be made of lead-free or lead-containing transparent acrylic material.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows: 1. In the initial state, the main clamps of the two trunk restraint mechanisms are in an outward-rotated open state, with a large operating space between the two main clamps. When performing X-ray examinations on children, the child is first placed on the base, and then the mounting seats of the two trunk restraint mechanisms are controlled to rotate inward and close by the translation and rotation components before being translated and brought closer together, gradually clamping and restraining the child's trunk. At the same time, the child's arms are raised and fixed on the upper limb restraint mechanism, forming a posture similar to raising hands, so that the child's entire chest cavity is fully opened, which is conducive to clear X-ray imaging of the child's trunk. It also achieves a fast and efficient restraint and fixation effect on the child's body. Furthermore, by rotating the rotating table, different parts of the child's body can be oriented towards the X-ray machine to meet different imaging needs, significantly reducing the labor intensity of medical staff.

[0015] 2. In this invention, during the process of controlling the two mounting seats to clamp and restrain the child's torso, the child's arms are raised, and the child's hands are placed on the handles. The child will naturally grasp the handles, and the child's fingers can be passed through the finger cots to guide the child to grasp the handles, thereby effectively increasing the child's sense of security during X-ray imaging and reducing the panic caused by restraint. Finally, when the mounting seats are fully closed, the main clamp and the auxiliary clamp work together to restrain the child's body, putting the child in a posture similar to raising their hands. At the same time, the operator can also rotate the adjusting outer cylinder to extend and retract the adjusting inner rod relative to the adjusting outer cylinder, thereby causing the support rod to drive the auxiliary clamp to rotate, allowing the child's arms to open. The opening angle of the child's arms can be adjusted by controlling the total length of the adjusting outer cylinder and the adjusting inner rod to meet different X-ray imaging needs and ensure the child's comfort during X-ray imaging.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0021] In some embodiments, please refer to the accompanying drawings. Figures 1-7 A child care restraint device includes a frame 1; a rotating platform 2 is rotatably mounted on the top of the frame 1, an angle positioning component 4 for controlling the angle of the rotating platform 2 is installed between the frame 1 and the rotating platform 2, and a seat base 3 is fixedly mounted on the bottom of the rotating platform 2; a movable restraint mechanism 5 is installed on the rotating platform 2, the movable restraint mechanism 5 includes a torso restraint mechanism 51 and an upper limb restraint mechanism 52, the two torso restraint mechanisms 51 are symmetrically mounted on the rotating platform 2, and an upper limb restraint mechanism 52 is installed on the side of each torso restraint mechanism 51.

[0022] The torso restraint mechanism 51 includes a mounting base 511, a support base plate 512, a main clamping plate 513, a translational rotation assembly, and a closing self-locking assembly. The translational rotation assembly is mounted on the rotary table 2, and the mounting base 511 is mounted on the moving end of the translational rotation assembly. The top of the mounting base 511 is engaged with the bottom of the main clamping plate 513, and the bottom of the mounting base 511 is fixedly connected to the top of the support base plate 512. The bottom surface of the support base plate 512 slides against the top surface of the rotary table 2. The mounting base 511 is also equipped with a closing self-locking assembly, which is used to automatically lock the main clamping plate 513 in the two torso restraint mechanisms 51 after closing to achieve restraint of the child's torso.

[0023] In the initial state of this invention, the main clamps 513 in the two trunk restraint mechanisms 51 are in an outward-rotated open state, and the operable space between the two main clamps 513 is relatively large. When performing X-ray examinations on children, the child is first placed on the sitting base 3. Then, the mounting seats 511 in the two trunk restraint mechanisms 51 are controlled to rotate inward and close by the translation and rotation components, and then move closer to each other, gradually clamping and restraining the child's trunk. At the same time, the child's arms are raised and fixed on the upper limb restraint mechanism 52, forming a posture similar to raising hands, so that the child's entire chest cavity is fully opened, which is conducive to clear X-ray imaging of the child's trunk. It also achieves a fast and efficient restraint and fixation effect on the child's body. Furthermore, by rotating the rotating table 2, different parts of the child's body can be oriented towards the X-ray machine to meet different imaging needs, significantly reducing the labor intensity of medical staff.

[0024] In some embodiments, the angle positioning component 4 includes a socket 41, a rod 42, and a support block 43. Multiple sockets 41 are arranged in a circumferential array on the side of the rotary table 2. The support block 43 is fixedly mounted on the top of the frame 1, and a rod 42 for insertion into the socket 41 is slidably connected to the support block 43. After rotating the rotary table 2, inserting the rod 42 into the corresponding socket 41 locks the angle of the rotary table 2, allowing different parts of the child's body to face the X-ray machine.

[0025] In some embodiments, the translation and rotation assembly includes a limiting groove 514, a limiting slider 515, and a rotating rod 516. The limiting groove 514 is provided on the rotary table 2. The limiting slider 515 is slidably connected to the limiting groove 514. The bottom of the rotating rod 516 is fixedly connected to the top of the limiting slider 515, and the top of the rotating rod 516 is rotatably connected to the mounting base 511. The self-locking closure assembly includes a front ratchet assembly and a rear ratchet assembly. The front ratchet assembly is mounted on the rotary table 2 and located between the limit slider 515 and the frame 1. The rear ratchet assembly is mounted between the rear sides of the mounting seats 511 in the two torso restraint mechanisms 51. The front ratchet assembly and the rear ratchet assembly are used to ensure that the mounting seats 511 in the two torso restraint mechanisms 51 can only move towards each other.

[0026] The front ratchet assembly includes a front ratchet plate 517 and a front pawl 518. The front ratchet plate 517 is fixedly mounted on the rotary table 2 and located in front of the limiting slide groove 514. One end of the front pawl 518 is hinged to the side of the limiting slider 515, and the other end of the front pawl 518 is engaged with the front ratchet plate 517. A torsion spring is also fixedly installed between the front pawl 518 and the limiting slider 515 so that the end of the front pawl 518 always abuts against the front ratchet plate 517. The rear ratchet assembly includes a rear ratchet plate 519 and a rear pawl 5110, which are located between the rear sides of two mounting seats 511. The rear ratchet plate 519 is fixedly connected to the rear side of the mounting seat 511 in one of the torso restraint mechanisms 51. One end of the rear pawl 5110 is hinged to the rear side of the mounting seat 511 in the other torso restraint mechanism 51, and the other end of the rear pawl 5110 is engaged with the rear ratchet plate 519. A torsion spring is also fixedly installed between the rear pawl 5110 and the mounting seat 511, so that the end of the rear pawl 5110 always abuts against the rear ratchet plate 519. When using this invention, after the child sits on the seat 3, the mounting bases 511 in the two trunk restraint mechanisms 51 are rotated inward to close, and then pushed inward to make the main clamping plates 513 on both sides gradually approach each other. Through the cooperation of the front ratchet plate 517 and the front pawl 518, and the cooperation of the rear ratchet plate 519 and the rear pawl 5110, the two mounting bases 511 can only move towards each other, gradually clamping and restraining the child. This is not only convenient to operate, but also provides a large internal operating space when the two main clamping plates 513 are open, which facilitates the operator to adjust the child's posture and is beneficial to the quality of subsequent X-ray imaging.

[0027] In some embodiments, the upper limb restraint mechanism 52 includes an adjustable arm restraint assembly and a hand restraint assembly, the bottom of which is connected to the top of the support base plate 512, and the top of which is connected to the hand restraint assembly.

[0028] Specifically, the adjustable arm restraint assembly includes a support rod 521, a secondary clamping plate 522, and an angle adjustment assembly. The bottom of the support rod 521 is hinged to the top of the support base plate 512. Multiple locking blocks that engage with the support rod 521 are fixedly installed at equal intervals along the length of the secondary clamping plate 522. An angle adjustment assembly is installed between the support rod 521 and the support base plate 512.

[0029] The angle adjustment assembly includes a connecting block 523, an adjusting outer cylinder 524, and an adjusting inner rod 525. The bottom of the connecting block 523 is hinged to the top of the supporting base plate 512. One end of the adjusting outer cylinder 524 is rotatably connected to the connecting block 523. The other end of the adjusting outer cylinder 524 is threadedly connected to one end of the adjusting inner rod 525. The end of the adjusting inner rod 525 away from the adjusting outer cylinder 524 is hinged to the outer wall of the supporting rod 521. An anti-slip layer is provided on the outer side of the adjusting outer cylinder 524.

[0030] The hand restraint assembly includes an L-shaped handle 526, a grip 527, and finger sleeves 528. One end of the L-shaped handle 526 is telescopically mounted inside the top of the support rod 521. The grip 527 is fixedly connected to the other end of the L-shaped handle 526. Multiple finger sleeves 528 are fixedly mounted on the grip 527. The grip 527 is made of foam material, which is soft and comfortable.

[0031] When using this invention, during the process of controlling the two mounting seats 511 to clamp and restrain the child's torso, the child's arms are raised, and the child's hands are placed on the handles 527. The child will naturally grasp the handles 527, and the child's fingers can be passed through the finger sleeves 528 to guide the child to grasp the handles 527, thereby effectively increasing the child's sense of security during X-rays and reducing the panic caused by restraint. Finally, when the mounting seats 511 are completely closed, the main clamp 513 and the auxiliary clamp 522 work together to restrain the child's body, putting the child in a posture similar to raising their hands. At the same time, the operator can also rotate and adjust the outer cylinder 524, causing the inner rod 525 to extend and retract relative to the outer cylinder 524, thereby causing the support rod 521 to drive the auxiliary clamp 522 to rotate, allowing the child's arms to open. The opening angle of the child's arms can be adjusted by controlling the total length of the outer cylinder 524 and the inner rod 525 to meet different X-ray imaging needs and ensure the child's comfort during X-rays.

[0032] In some embodiments, a retractable lever 529 is rotatably mounted inside the L handle 526. The end of the finger sleeve 528 passes through the grip 527 and the L handle 526, is wrapped around the retractable lever 529, and is fixedly connected to the retractable lever 529. By rotating the retractable lever 529, the finger sleeve 528 can be tightened or extended, so that the finger sleeve 528 can meet the restraint effect for fingers of different sizes. A fastening bolt is also threaded to the outside of the adjusting inner rod 525. By screwing in the fastening bolt to abut against the retractable lever 529, the retractable lever 529 can be fixed relative to the L handle 526.

[0033] In this embodiment, the main clamping plate 513 and the secondary clamping plate 522 are on the same circumference, with the secondary clamping plate 522 located in the middle of the main clamping plate 513. The two are spliced ​​together to form a semi-circular clamping plate structure to fit the child's body and achieve a good and stable restraint effect on the child's body.

[0034] In this embodiment, the quick-release modular design of the main clamp 513 and the auxiliary clamp 522 facilitates their disassembly and replacement, preventing cross-infection when different children use the device. The main clamp 513 and the auxiliary clamp 522 are made of lead-free or lead-containing transparent acrylic material, and the front end of the main clamp 513 has an imaging window, allowing X-rays to pass through the lead-free main clamp 513, the connecting block 523, and the imaging window with almost no loss, providing high-quality and clear imaging of the child's body parts. The lead-containing part blocks the X-rays, protecting the non-detection areas of the child.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
