Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a neonatal position fixer for an invasive ventilator. Background Art

[0002] An invasive ventilator is a medical device used to assist or replace a patient's spontaneous breathing. It is directly connected to the patient's airway through endotracheal intubation or tracheotomy to provide pressurized air or other gas mixtures to ensure adequate gas exchange and stable vital signs. In the neonatal intensive care unit, invasive ventilators are often used to assist ventilation therapy for critically ill premature or weak newborn patients. Due to the special constitution of newborn patients, special attention should be paid to position management when using invasive ventilators to ensure the safe use of the ventilator circuit, maintain effective mechanical ventilation, and reduce the occurrence of complications.

[0003] At present, in order to prevent neonatal lung compression, medical practice usually uses sloped lying position or side-lying position to adjust the posture of the newborn. This posture management method is particularly important during invasive ventilator-assisted ventilation. It can not only help prevent milk reflux, but also significantly improve the comfort of the newborn. At the same time, in this operation, medical staff will also use pads or bedding stacking to ensure that the newborn maintains the correct correction position. However, this method has certain limitations: due to the soft material of pads and bedding, it is difficult to provide stable restrictions and effective restraints, resulting in insufficient fixation of the body position and easy displacement. At the same time, this method is also difficult to accurately and quickly ensure the angle and stability of the body position. When the newborn's own activities or the operation contact of medical staff may cause changes in the angle of body tilt, thus affecting the treatment effect.

[0004] Therefore, in view of the above problems, it is necessary to propose a newborn position fixator suitable for invasive ventilator. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings in the prior art, the present invention provides a neonatal position fixer suitable for an invasive ventilator.

The lower end of the connecting rod slides through the corresponding lower limb support plate and upper limb lifting plate, and an elastic member 1 is arranged between the connecting rod and the corresponding lower limb support plate and upper limb lifting plate. An assembly plate is arranged at the bottom of the bed, and an electric push rod 2 with a telescopic end facing upward is installed on the assembly plate. A connecting frame is connected to the telescopic end of the electric push rod 2, and both sides of the connecting frame are respectively in contact with and cooperate with the bottom end of the connecting rod on the same side.

[0012] As a further preferred scheme, the lifting mechanism also includes a pushing frame arranged at the bottom of the upper limb lifting plate, and inclined grooves are opened on both sides of the pushing frame. An electric push rod with the telescopic end facing backward is installed at the bottom of the lower limb support plate, and a push-pull rod is connected to the telescopic end of the electric push rod. The two ends of the push-pull rod are respectively slidably inserted into the inclined grooves on the same side, so as to push the upper limb lifting plate and lift the upper limb position of the newborn.

[0013] As a further preferred embodiment, a fitting component is provided on the bed body, which includes a skin-friendly pad placed on the bed body, which covers the lower limb support plate and the upper limb lifting plate, and Velcro is provided on both sides and the middle of the bottom of the skin-friendly pad, on which buckling rings are fitted, and the buckling rings are buckled on the hinged rods or mounting rods at corresponding positions to fix the position of the skin-friendly pad.

[0014] As a further preferred embodiment, at least two engaging grooves are also provided on both sides of the bed body, and a clamping mechanism for clamping and fixing bedding is arranged in the engaging grooves of the bed body. The clamping mechanism includes support rods respectively arranged in the engaging grooves, and sliding blocks are slidably arranged on the support rods, and the sliding blocks are provided with clamping parts for clamping bedding.

[0015] As a further preferred solution, the clamping mechanism also includes an insertion rod slidably inserted into each sliding block, an elastic member 2 is arranged between the insertion rod and the corresponding sliding block, and the support rod is also provided with arranged insertion holes that are plugged into and cooperate with the corresponding insertion rod.

[0016] As a further preferred solution, it also includes a supporting plate arranged on the rear side of the bed, and adjusting rods are arranged in an arranged and slidable manner on the supporting plate.

[0017] As a further preferred embodiment, the length of the lower limb support plate is shorter than that of the upper limb lifting plate so as to be suitable for the placement of the newborn's head and upper body, and the corners of the lower limb support plate and the upper limb lifting plate are rounded.

[0018] As a further preferred embodiment, the angle between the inclined groove and the front-rear axial horizontal line does not exceed thirty degrees.

[0019] The present invention overcomes the shortcomings of the prior art and can achieve the following beneficial effects:

[0020] 1. The present invention realizes precise adjustment and firm fixation of the neonatal body position by introducing a lifting mechanism and a limiting mechanism; when it needs to be adjusted to a sloped lying position, the electric push rod drives the upper limb lifting plate to lift up, and accurately controls the angles of the upper body and head of the neonate; and the adjustment of the lateral position is completed through the coordinated work of the connecting rod, the hinged rod and the sliding rod, and ensures that the adjusted position can be effectively fixed. These two sets of mechanisms can operate independently or in combination to form a surround-type limiting structure, which provides more stable and reliable support than traditional soft materials, prevents the neonate from position shifting during treatment, and thus ensures the realization of the treatment effect.

[0021] 2. The present invention adopts a skin-friendly pad design through the setting of a fitting component to improve the comfort of the newborn. At the same time, Velcro and buckle rings are used to ensure the fixation of the skin-friendly pad to avoid displacement during use and facilitate subsequent replacement and disassembly. Furthermore, the skin-friendly pad cooperates with the limiting structure to achieve surround limiting, which further enhances the safety of the newborn and ensures its stability and comfort throughout the treatment process.

[0022] 3. In order to facilitate the management of bedding on the newborn's bed, the present invention is also provided with a clamping mechanism, which can effectively fix the corners of the bedding through the clamping and fixing of the clamping member, thereby keeping the bed tidy.

[0023] 4. The present invention provides a placement ring and an adjustment rod, so that the pipeline of the invasive ventilator can be properly placed, avoiding the problem of twisting or falling off due to external force, thereby improving the safety and effectiveness of the treatment process.

[0036] Embodiment: An invasive ventilator neonatal position fixator, such as Figure 1-Figure 7 As shown, including:

[0037] Bed 1;

[0038] The positioning frame 11 is arranged on the top of the bed body 1, and its front and rear sides are convex, which can wrap the front and rear sides of the bed body 1 and limit the use area inside it, so as to effectively limit the range of movement of the newborn and prevent the pipe from falling off or being improperly positioned due to the movement of the newborn. A guide frame 12 is arranged on the positioning frame 11, and a light shield 13 attached to the positioning frame 11 is slidably arranged on the front and rear sides of the guide frame 12. The inner wall of the light shield 13 is coated with a light-shielding coating, and the light shield 13 can be slid and closed when needed to protect the newborn from light stimulation and prevent flying insects from entering;

[0039] An invasive ventilator 2 is installed at the rear of the bed 1. Through holes 111 for inserting pipelines are arranged on the rear side of the positioning frame 11, so as to stabilize the extension path and position of the air pipeline and ensure the smooth flow of the pipeline.

[0040] The lifting mechanism 3 is arranged on the bed body 1, and the lifting mechanism 3 includes a lower limb support plate 31 embedded in the front side of the top of the bed body 1, the highest point of the lower limb support plate 31 is level with the bed body 1, and an upper limb lifting plate 32 for supporting the head and upper body parts is hingedly arranged at the rear end of the lower limb support plate 31, allowing the upper limb lifting plate 32 to be hingedly raised or lowered, thereby realizing the raising or lowering of the upper limb part of the body of the newborn, and the corners of the lower limb support plate 31 and the upper limb lifting plate 32 are rounded to ensure the safety of the newborn when contacting the corners of the two, and the highest points of the upper limb lifting plate 32 and the lower limb support plate 31 are on the same horizontal line, so that at the beginning, the two can be stably embedded in the bed body 1, thereby ensuring the comfort of the newborn when lying flat, and at the same time, in order to meet ergonomics, the length of the lower limb support plate 31 is adjusted to be smaller than the upper limb lifting plate 32, so as to be suitable for the ratio of the head and upper limbs of the upper body of the newborn, thereby ensuring sufficient space during use;

[0041] The limiting mechanism 4 is arranged at the bottom of the bed body 1 and is used to limit the body position of the newborn. The limiting mechanism 4 includes a mounting rod 42. The lower limb support plate 31 and the upper limb lifting plate 32 are jointly provided with three left-right engaging grooves 41, two of which are respectively located at the head and tail ends of the upper limb lifting plate 32, and the other engaging groove 41 is located at the tail end of the lower limb support plate 31. The mounting rods 42 are fixedly arranged at the middle position of the engaging grooves 41, so that the positions of the three mounting rods 42 correspond to the head, upper body and lower body of the newborn, respectively, laying a position foundation for subsequent body position fixation. Articulated rods 43 are hingedly arranged at the left and right ends of the mounting rods 42, and the articulated rods 43 are also embedded in the engaging grooves 41 at the corresponding positions, so that each rod body can be fitly arranged on the lower limb support plate 31 and the upper limb lifting plate 32, thereby ensuring the overall aesthetics and For comfort of use, a sliding rod 431 is slidably provided at the bottom of the hinged rod 43, and the sliding rod 431 slides left and right. A connecting rod 47 is hinged on the sliding rod 431, and the lower end of the connecting rod 47 slides through the corresponding lower limb support plate 31 or upper limb lifting plate 32, and an elastic member 48 is provided between the connecting rod 47 and the corresponding lower limb support plate 31 and upper limb lifting plate 32. In this embodiment, the elastic member 48 is a spring, which can provide elastic support for the reset operation of the connecting rod 47, and an assembly plate 44 is provided at the bottom of the bed body 1. The assembly plate 44 is placed on the four legs of the bed body 1 to ensure the assembly stability of the assembly plate 44. An electric push rod 45 with a telescopic end facing upward is installed in the middle of the assembly plate 44, and a connecting frame 46 is connected to the telescopic end of the electric push rod 45, and the left and right sides of the connecting frame 46 are respectively in contact with the bottom end of the connecting rod 47 on the same side.

[0042] Specifically, in the above-mentioned limiting mechanism 4, the electric push rod 2 45 is the main driving member, which drives the connecting frame 46 to move upward so that it can contact and push the connecting rod 47 to move, and then the connecting rod 47 complies with the sliding and hinged action of the operation, forcing the hinged rod 43 above it to be pushed up and tilted, and the sliding rod 431 slides accordingly, thereby adjusting the position between the hinged rod 43 and the connecting rod 47, thereby realizing the lifting of the hinged rods 43 on both sides, and by adjusting the angle between the hinged rods 43 and the mounting rods 42 on both sides, a structure with a recessed middle and slightly raised ends is formed, so as to gently and firmly limit the body position of the newborn. Combined with the auxiliary support function of the upper limb lifting plate 32, this design provides a full range of position fixing solutions for newborns, which can not only quickly and accurately maintain the required body position angle and stability, but is also particularly suitable for situations where both slope lying position and lateral lying position need to be supported, thereby ensuring that the newborn maintains the correct posture when using the invasive ventilator 2, so as to ensure and enhance the stability and effectiveness of the treatment effect.

[0043] like Figure 2 and Figure 4As shown, the lifting mechanism 3 also includes a pushing frame 35 arranged at the bottom of the upper limb lifting plate 32, and inclined grooves 36 are provided on the left and right sides of the pushing frame 35. Taking the left view as the main viewing angle, the inclined grooves 36 are inclined at a backward inclination angle of no more than 30 degrees relative to the horizontal line of the front and rear axes, thereby ensuring that when the upper limb lifting plate 32 is raised, its inclination angle is maintained within 30 degrees, thereby providing a stable and suitable slope support for the newborn. An electric push rod 33 with a telescopic end facing backward is installed at the bottom of the lower limb support plate 31, and a push-pull rod 34 is connected to the telescopic end of the electric push rod 33. The left and right ends of the push-pull rod 34 are respectively slidably inserted into the inclined grooves 36 on the same side, so as to push the upper limb lifting plate 32 and lift the upper limb position of the newborn.

[0044] like Figure 3 and Figure 8 As shown, a fitting component 5 is provided on the bed body 1, and the fitting component 5 includes a skin-friendly pad 51 placed on the bed body 1, and the skin-friendly pad 51 can increase the comfort of use. The skin-friendly pad 51 covers the lower limb support plate 31 and the upper limb lifting plate 32, and Velcro 52 is provided on both sides and the middle of the bottom of the skin-friendly pad 51. The Velcro 52 is fitted with a buckling ring 53, and the buckling ring 53 is buckled on the hinge rod 43 or the mounting rod 42 at the corresponding position. The Velcro 52 and the buckling ring 53 are used to fix the skin-friendly pad 51 in place to ensure that the skin-friendly pad 51 will not shift and is also convenient for subsequent disassembly and replacement.

[0045] like Figure 3 and Fig. 9 As shown, three engaging grooves 41 are also provided on the left and right sides of the bed body 1. A clamping mechanism 6 for clamping and fixing bedding is provided in the engaging grooves 41 located on the bed body 1. The clamping mechanism 6 includes support rods 61 respectively arranged in the engaging grooves 41 at the front and rear ends, and sliding blocks 62 are slidably provided on the support rods 61. The sliding blocks 62 are all provided with clamping members 63. The clamping members 63 are used to firmly clamp and fix the bedding to prevent the bedding from slipping and affecting the safety and comfort of the newborn.

[0046] like Figure 3 and Fig. 9 As shown, the clamping mechanism 6 also includes an insertion rod 64 that is slidably inserted into each sliding block 62, and an elastic member 65 is provided between the insertion rod 64 and the corresponding sliding block 62. In this embodiment, the elastic member 65 is a spring, and the support rod 61 is also arranged with a socket 611 that is plugged into and cooperates with the corresponding insertion rod 64, so that the sliding block 62 and the upper parts can be locked in position after moving.

[0047] like Figure 2 and Figure 3As shown, it also includes a supporting plate 7 arranged on the rear side of the bed body 1, and adjusting rods 71 ​​are arranged on the supporting plate 7 in an arranged and slidable manner. The top ends of the adjusting rods 71 ​​are rotatably provided with placement rings 72 for placing treatment pipes. Threaded rods 73 matching the number of adjusting rods 71 ​​are also threadedly penetrated on the supporting plate 7, and the ends of the threaded rods 73 abut against the adjacent adjusting rods 71 ​​to fix the sliding position of the adjusting rods 71, so as to manage and organize various treatment pipes and ensure that the pipes are arranged in an orderly manner and do not interfere with the treatment of newborns.

[0048] When in use, the skin-friendly pad 51 is first covered on the lower limb support plate 31 and the upper limb lifting plate 32, so that the Velcro 52 thereon is in contact with the buckle ring 53 at the corresponding position, thereby ensuring that the skin-friendly pad 51 is placed flat on the bed body 1, and then the medical staff places the newborn on the skin-friendly pad 51, and pulls the pipeline of the invasive ventilator 2 through the through hole 111 at the appropriate position. The pipeline can also be passed through the placement ring 72 as needed, and the placement ring 72 is rotated to adjust the pipeline angle, and then the corresponding adjustment rod 71 is pushed to slide up and down on the bearing plate 7 to adjust the rear end height of the pipeline. After the adjustment is completed, the threaded rod 73 can be rotated to push it closer to the position of the corresponding adjustment rod 71, and the adjustment rod 71 is abutted and fixed, so as to stabilize the adjusted position of the pipeline, and then the pipeline is pulled to the newborn for assembly and use;

[0049] Then adjust the body position according to the newborn's physical treatment needs. You can choose a sloped lying position or a side-lying position:

[0050] First, when the newborn's body position needs to be adjusted to a sloped lying position, the electric push rod 33 is started to drive the push-pull rod 34 connected thereto to move backward, and the push-pull rod 34 slides along the inclined slot 36 of the push frame 35 as it moves, and simultaneously drives the push frame 35 and the upper limb lifting plate 32 to rotate in accordance with the push, and then the upper limb lifting plate 32 is lifted upward, and the bottom end of the connecting rod 47 placed thereon is separated from the contact with the connecting frame 46 until the adjustment is completed, and the newborn's lower limbs will be stably placed on the lower limb support plate 31, and the head and upper body will be lifted in accordance with the upper limb lifting plate 32, thereby limiting the upper limb position of the newborn, reducing the pressure on the lungs, and avoiding the reflux of milk, so as to improve the comfort of the newborn;

[0051] Secondly, when the newborn's body position needs to be adjusted to the lateral position, the electric push rod 45 is started, which drives the connecting frame 46 to move upward, so that it contacts the connecting rod 47 at the corresponding position, and pushes the connecting rod 47 to slide upward on the corresponding lower limb support plate 31 or upper limb lifting plate 32, and the elastic member 48 is deformed accordingly. As it moves, the connecting rod 47 pushes the hinge rod 43, so that the hinge rod 43 rotates on the mounting rod 42 and moves upward, and at the same time, the connecting rod 47 and the sliding rod 431 are hinged and rotated, and then the sliding rod 431 slides on the hinge rod 43 in accordance with the movement, so as to adapt to the lifting of the hinge rod 43. As the hinge rods 43 on both sides are lifted, the skin-friendly pad 51 is pushed and bent, forming a shape with protrusions on both sides and a concave shape in the middle, so as to effectively limit the lateral angle and the position on both sides of the newborn, thereby ensuring the stability of the newborn's body position;

[0052] Third, when the position of the newborn is not easy to adjust and fix, the medical staff can combine the above two operations to adjust to a position suitable for restricting the newborn's position. In this process, the upper limb lifting plate 32 can be lifted in combination with the first operation method to preliminarily restrict the newborn's head and upper limbs, and then combined with the above second operation method to lift the hinged rods 43 on both sides, so that the skin-friendly pads 51 are raised on both sides, and the newborn's upper limb position is stably restricted. At the same time, the use of the skin-friendly pads 51 on both sides can be combined to further stabilize the newborn's side positioning, forming a surround limit, thereby effectively fixing the newborn's position.

[0053] Then it can be used selectively according to needs. If the bed body 1 needs to be shielded from light, the light-shielding covers 13 on both sides can be pushed to slide inward and close together so that the two are closed, thereby blocking the external light source to a certain extent and also blocking the entry of flying insects. When it is necessary to cover the newborn with bedding, the corners of the bedding can be clamped on the clamping members 63 at the corresponding positions, and then the insertion rod 64 can be pulled up to disengage it from the insertion hole 611, and the elastic member 2 65 will be deformed accordingly. Then, the sliding block 62 can be pushed to slide on the support rod 61 to adjust the corner positions of the bedding and the flatness of the overall laying of the bedding. After the position adjustment is completed, the insertion rod 64 can be released, and the elastic member 2 65 will be reset accordingly. The insertion rod 64 is inserted into the corresponding insertion hole 611, thereby fixing the sliding block 62 and the upper components thereof. From then on, the overall operation process of the device is completed.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
