Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a ventilator tubing fixator for intensive care units. Background Technology

[0002] The ventilator tubing is the key channel connecting the ventilator and the patient. Its function is to deliver oxygen to the patient's airway. The layout and installation of the ventilator tubing directly affect the ventilation effect and patient safety. In order to ensure that the tubing is free from bends and pressure and that airflow is always unobstructed during the layout process, a special tubing retainer is required.

[0003] Ventilator tubing retainers are important devices used to stabilize and manage ventilator tubing, preventing tubing from dislodging, maintaining patency, reducing traction, and facilitating medical and nursing operations. On the one hand, the retainer needs to connect the tubing to the bed or equipment to prevent the tubing from being disconnected due to patient movement or external force. On the other hand, it also needs to support the tubing to allow it to stretch naturally and prevent the tubing from bending or folding and affecting airflow.

[0004] In practical use, it has been found that the clamping grooves of current fixtures are mostly custom-made for pipes of specific diameters, lacking flexibility and making it difficult to adapt to pipes of different specifications (such as children's and adults' pipes). In addition, the pipes sag due to their own weight, generating downward tension, especially for pipes with smaller diameters. After the pipes sag, the inner diameter is squeezed inward and becomes smaller, increasing airflow resistance. Utility Model Content

[0005] Therefore, this utility model provides a ventilator tubing fixator for intensive care units to solve the problem that existing tubing fixators cannot adapt to tubing of multiple sizes and cannot respond to changes in tubing tension, resulting in tubing compression.

[0006] To achieve the above objectives, the embodiments of this utility model provide the following technical solutions:

[0007] A ventilator tubing fixation device for intensive care units includes an outer support frame and an airbag pad disposed inside the outer support frame. The tubing body is spirally wound on the surface of the airbag pad. Multiple annular spacers capable of moving axially along the outer support frame are installed on the outer support frame. An adjustment component is installed on the same side of the multiple annular spacers, and the spacing between the two sides of the multiple annular spacers is adjusted by the adjustment component to clamp and fix the tubing body.

[0008] As a preferred embodiment of this utility model, the adjustment assembly includes a telescopic frame disposed between all the annular spacers, a torque clamp provided on the two outermost annular spacers, a bidirectional screw provided between the two ends of the outer support frame, and the torque clamp threaded onto the bidirectional screw. When the bidirectional screw rotates forward and backward, it drives the telescopic frame to expand or contract, thereby driving all the annular spacers to move away from the extension or closer to the clamping.

[0009] As a preferred embodiment of the present invention, the outer support frame includes two parallel fixed plates and a plurality of evenly distributed upper limit rods disposed between the two fixed plates, with the five upper limit rods evenly distributed at equal angles on the upper half of the fixed plates.

[0010] The two ends of the airbag cushion are attached to the inner walls of the two fixed plates, and the bidirectional lead screw is rotatably connected to the fixed plates.

[0011] In a preferred embodiment of this utility model, the annular spacer slides along the length direction of the upper limit rod via an adjusting component, and the lower half of the annular spacer is configured as a cavity structure, which can accommodate the pipeline body passing through.

[0012] In a preferred embodiment of this utility model, the telescopic frames are connected by multiple shafts, the middle shaft of the telescopic frame is welded to the annular spacer, and the shafts at both ends of the telescopic frame are welded to the torque clamp.

[0013] The embodiments of this utility model have the following advantages:

[0014] This invention employs an adjustable-spacing annular spacer to provide lateral physical protection for the ventilator tubing, preventing lateral compression between tubing sections. The central support uses a pressure-adjustable dual-chamber airbag structure to achieve a synergistic effect of dynamic pressure compensation and rigid support. It is compatible with various specifications of ventilator tubing, absorbs the downward tension generated by tubing of different specifications, avoids tubing compression caused by improper force, and thus ensures smooth airflow.

[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1 to 4 This utility model provides a ventilator tubing fixation device for intensive care units, including an outer support frame 1 and an airbag pad 4 disposed inside the outer support frame 1. The tubing body 5 is spirally wound on the surface of the airbag pad 4. Multiple annular spacers 3 that can move along the axial direction of the outer support frame 1 are installed on the outer support frame 1. An adjustment component 2 is installed on the same side of the multiple annular spacers 3, and the distance between the two sides of the multiple annular spacers 3 is adjusted by the adjustment component 2 to clamp and fix the tubing body 5.

[0027] In this embodiment, the spacing of the annular spacers 3 is first adjusted according to the diameter of the pipe body 5 so that the groove width of the annular spacers 3 is expanded to match the pipe diameter. The spacing of the annular spacers 3 is adjusted by the adjusting component 2. This adjustment process keeps the spacing between the annular spacers 3 evenly spread or close to ensure support stability.

[0028] Then, the tube body 5 is wound around the airbag pad 4. During the winding process, each turn of the tube body 5 is embedded in the groove of the annular spacer 3 and fits against the surface of the annular spacer 3. The annular spacer 3 separates the air tubes, forming a physical barrier. This not only separates the tube body 5 to prevent lateral compression, but also provides dynamic buffering support through the airbag pad 4. When the tube body 5 is compressed due to its own weight, the airbag pad 4 automatically compresses to absorb stress, keeping the inner diameter of the air tube constant and ensuring the airflow rate.

[0029] like Figure 2 and Figure 3 As shown, the adjustment assembly 2 includes a telescopic frame 203 disposed between all the annular spacers 3. Torque clamps 202 are provided on the two outermost annular spacers 3. A bidirectional screw 201 is provided between the two ends of the outer support frame 1, and the torque clamps 202 are threaded onto the bidirectional screw 201. When the bidirectional screw 201 rotates forward and backward, it drives the telescopic frame 203 to expand or contract, so as to drive all the annular spacers 3 away from the extension or close to the clamp.

[0030] In this embodiment, the bidirectional screw 201 is rotated according to the diameter of the tubing body 5. When the trachea diameter is large, the bidirectional screw 201 is rotated clockwise to drive the torque clamps 202 at both ends to slide outward. The telescopic frame 203 pushes the annular spacer 3 to unfold equidistantly along the surface of the airbag pad 4. The entire fixation device is fixed by clamping it onto the side rail of the hospital bed through the two torque clamps 202. The torque clamps 202 have built-in anti-slip rubber, which, together with the bidirectional screw 201 with a self-locking structure at the top, ensures that the annular spacer 3 remains fixed after adjustment, preventing the tubing body 5 from shifting or being squeezed due to external impact, and ensuring the continuous and stable operation of the ventilation system.

[0031] like Figure 2 and Figure 4 As shown, the outer support frame 1 includes two parallel fixed plates 102 and a plurality of evenly distributed upper limit rods 101 disposed between the two fixed plates 102. The five upper limit rods 101 are evenly distributed at equal angles on the upper half of the fixed plates 102.

[0032] The two ends of the airbag cushion 4 are attached to the inner walls of the two fixing plates 102, and the bidirectional lead screw 201 is rotatably connected to the fixing plate 102.

[0033] The annular spacer 3 slides along the length of the upper limit rod 101 via the adjusting component 2. The lower half of the annular spacer 3 is designed as a cavity structure, which can accommodate the pipeline body 5 through which it passes.

[0034] In this embodiment, the airbag 4 is fixed by placing two fixing plates 102 at both ends of the airbag 4 and bonding them to the airbag 4. Five upper limit rods 101 are placed on the upper half of the fixing plates 102, forming a stable outer support frame 1. The bidirectional screw 201 is located on the lower half of the fixing plates 102 and is rotatably connected to the fixing plates 102. Together with the upper limit rods 101, it forms a rigid support to support the annular spacer 3 and the airbag 4. When the annular spacer 3 slides laterally, the upper limit rods 101 control the annular spacer 3 to always slide horizontally along the airbag 4 and not squeeze the airbag 4. At the same time, the five upper limit rods 101 are equiangularly distributed to form an arc-shaped protective barrier, which can shield and protect the upper half of the pipe body 5 wrapped around the surface of the airbag 4 and prevent the pipe body 5 from being impacted by external forces.

[0035] The cavity in the lower half of the annular spacer 3 allows the pipe body 5 to pass through easily. When the pipe body 5 is bolted along the airbag pad 4, it passes through the cavity at the bottom, ensuring that the pipe body 5 is not squeezed by the annular spacer 3 when it is being wound along the airbag pad 4. At the same time, it can further limit the pipe body 5 and prevent the pipe body 5 from shifting.

[0036] In addition, the airbag 4 adopts a double-layer airbag, including an outer airbag layer and an inner airbag layer. The front end of the outer airbag layer and the inner airbag layer are respectively equipped with two independent air valves. The air pressure of the outer airbag layer is relatively small, which can absorb the weight of the pipeline body 5 and undergo corresponding deformation, absorbing most of the vertical stress. The air pressure of the inner airbag layer is relatively large. When the outer airbag layer is compressed downward, the inner airbag layer provides reverse support to the pipeline body 5 and the outer airbag layer, preventing the pipeline body 5 from bending downward at an excessive angle.

[0037] It should be noted that when the diameter of the pipe body 5 is small and the material is soft, the air pressure can be reduced. When the diameter of the pipe body 5 is large and the material is hard, the air pressure can be increased appropriately. Reasonable changes in air pressure can effectively absorb the downward tension generated by the suspension of the pipe body 5, avoid the compression of the pipe body 5 due to improper force, and thus ensure smooth airflow.

[0038] like Figure 2 and Figure 3 As shown, the telescopic frames 203 are connected by multiple shafts. The middle shaft of the telescopic frame 203 is welded to the annular spacer 3, and the shafts at both ends of the telescopic frame 203 are welded to the torque clamps 202.

[0039] In this embodiment, the two intersecting drive rods of the telescopic frame 203 are connected by a shaft, and the drive rods can rotate along the shaft. The top of the shafts at both ends of the telescopic frame 203 is welded to two torque clamps 202, and the top is also connected to the two edge annular spacers 3. The remaining shafts in the middle of the telescopic frame 203 are connected to the annular spacers 3 in the middle.

[0040] When the bidirectional lead screw 201 rotates clockwise, the two torque clamps 202 extend laterally along the bidirectional lead screw 201 towards both ends. At this time, the included angle of the drive rod of the telescopic frame 203 decreases, the distance between the shafts increases, and the linkage shaft in the middle drives the distance between the annular spacers 3 to increase equidistantly. Conversely, the distance decreases. Through the cooperation of the telescopic frame 203 and the bidirectional lead screw 201, the position of the plate 102-shaped spacer is fixed while the annular spacer 3 is adjusted equidistantly.

[0041] By employing an adjustable-spacing annular spacer 3 to provide lateral physical protection for the ventilator tubing, lateral compression between tubing is prevented. The central support uses an adjustable-pressure dual-chamber airbag pad 4 to achieve a synergistic effect of dynamic pressure compensation and rigid support. This not only adapts to various specifications and sizes of ventilator tubing but also absorbs the downward tension generated by tubing of different specifications, avoiding tubing compression caused by improper force, thereby ensuring smooth airflow.

[0042] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
