Description

Technical Field

[0001] This utility model relates to the medical field, specifically a non-invasive respiratory support and fixation kit. Background Technology

[0002] In clinical settings such as non-invasive respiratory support and oxygen therapy, respiratory therapy devices such as nasal cannulas or high-flow nasal intubations need to be stably fixed to the patient's face. Currently, the mainstream fixation methods mainly rely on two technical solutions:

[0003] One approach involves directly applying medical tape, using pressure-sensitive tape to attach the tubing to the cheek. This technique has drawbacks such as impaired skin barrier function, adhesion failure due to sweat secretion, and mechanical skin damage from repeated application and removal.

[0004] The second method involves securing the cap with straps: A medical fabric cap is worn, with elastic straps sewn onto both sides. These straps connect to a nasal cannula placed in the center, and are then secured by wrapping around the head below the ears. This method has a significant drawback:

[0005] (1) Imbalance in mechanical distribution leads to excessive local pressure. Long-term wear can easily cause pressure sores on the cheeks, the back edge of the ear, the sides of the nose, and other key bearing areas.

[0006] (2) It is difficult to adjust the facial fit, the breathing tube is prone to displacement due to head rotation, and the straps need to be repeatedly tightened and loosened when the patient changes position, making the strap adjustment operation inconvenient.

[0007] (3) The overall size of the cap fixing device is too large, which affects the heat dissipation of the patient's head and the operation of imaging examinations. In addition, the cap is a fixed size and cannot be used for all head shapes.

[0008] In summary, existing fixation technologies generally suffer from three major problems: poor biomechanical adaptability, insufficient dynamic stability, and low skin compatibility. There is an urgent need to develop new fixation devices to solve these technical bottlenecks. Utility Model Content

[0009] The purpose of this invention is to provide a non-invasive respiratory support and fixation kit that can stably and effectively maintain a nasal catheter on the patient's face, allowing for easy adjustment of the tightness of the fixation according to the patient's face shape, adapting to different head or face shapes, and stably maintaining the position of the catheter during non-invasive respiratory treatment, while avoiding pressure sores during treatment.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A non-invasive respiratory support and fixation kit includes a band body, a catheter, a nasal cannula, an adhesive patch, and an adjustment structure. The catheter is connected to the band body via the nasal cannula. The adhesive patch is located at the catheter and / or the nasal cannula. The adjustment structure includes a fixing base, a control button, a linkage component, and a locking component. The control button and the linkage component are both located at the fixing base. The fixing base is detachably connected to the band body. The control button is movable to retract a portion of the band body into the fixing base. The locking component is located at the control button to restrict the state of the control button.

[0012] Compared with existing technologies, the non-invasive respiratory support and fixation kit that adopts the above technical solution has the following beneficial effects:

[0013] The non-invasive respiratory support and fixation kit of this invention, used in conjunction with a nasal cannula mask, stably positions the catheter and corresponding nasal plug in the nasal region. By attaching an accessory, a portion of the catheter is stably positioned above the patient's head. When the fixation seat is assembled onto the band, the coordinated adjustment of the fixation seat, control button, and linkage components allows the band to be partially stored within the fixation seat, thus adjusting the overall length of the band. This ensures that when the band is worn around the face, it remains stable and effectively in place, effectively securing the nasal end of the catheter. This avoids the cumbersome, poorly adaptable, and side-effects of existing methods using caps for fixation. Furthermore, adjusting the tightness of the band requires only one control button, making operation convenient and efficient.

[0014] Preferably, the linkage assembly includes a movable rod, a driven rod, a driving gear, a driven gear, and two take-up rods. The control button is rotatably mounted on the fixed base. The movable rod is located inside the fixed base and connected to the control button. The driving gear is connected to the movable rod. The driven rod is rotatably mounted inside the fixed base. The driven gear is connected to the driven rod and meshes with the driving gear. The two take-up rods simultaneously connect to the portion of the driven rod without the driven gear. The side wall of the fixed base has an opening and an outlet for the belt to pass through. Rotating the control button drives the two take-up rods to wind the belt. Utilizing the meshing relationship between the driving gear and the driven gear, and the cooperation relationship between the two take-up rods and the driven rod, rotating the control button causes the two take-up rods to form a group and rotate around the center of the driven rod, thereby achieving the purpose of winding the belt. Furthermore, since the multiple protruding teeth on the gear structure are evenly spaced, precise control and refined operation of the winding degree can be achieved, thus enabling fine-tuning of the belt tension.

[0015] Preferably, the fixing seat is divided into a base and a docking seat. The linkage component, opening, and outlet are all located on the docking seat. The edge of the docking seat is provided with multiple insertion pieces, the surfaces of which are elastically set. The edge of the base has multiple insertion slots on the side facing the docking seat, and the side of the base facing the skin has a skin-friendly surface. The skin-friendly surface effectively protects the skin. The disassembly and assembly of the fixing seat and the belt can be met by directly applying force to separate or directly snapping the connection. It is also convenient to use. The elasticity of the insertion pieces increases the connection stability without affecting subsequent disassembly operations. In addition, it is convenient to place the belt at the winding rod position in advance during assembly for subsequent belt adjustment operations.

[0016] Preferably, the base is provided with pressure-relieving portions at the positions corresponding to the opening and the exit. Since the portion of the belt corresponding to the opening and the exit will twist moderately during winding, the pressure-relieving portions can isolate this portion of the belt from the skin, preventing excessive pressure on the skin from this small area of ​​the belt, and without affecting the adjustment of the belt.

[0017] Preferably, the locking component includes a locking button, a shaped rod, an anti-detachment plate, and a damping layer. The shaped rod is retractable and located on the side of the fixed base where the control button is located. The anti-detachment plate is located at the end of the shaped rod inside the fixed base. The locking button is located at the end of the shaped rod corresponding to the outer side of the fixed base. The damping layer is located on the surface of the shaped rod. The side of the locking button facing the control button has multiple locking teeth, and the outer periphery of the control button has multiple limiting teeth corresponding to the locking teeth. Since the shaped rod cannot rotate on the fixed base, the locking teeth and limiting teeth are engaged or disengaged by pressing or pulling the locking button, thereby achieving the locking or unlocking function of the locking button and the control button. Furthermore, the deceleration and buffering effect of the damping layer and the limitation of the anti-detachment plate prevent the risk of the locking component directly disengaging due to excessive force.

[0018] Preferably, the adjustment structure is semi-transparent. This semi-transparent structure allows light to pass through the fixing base and other structures, facilitating medical personnel's inspection of the assembly and the winding of the belt, and simplifying assembly and subsequent adjustments to the belt tension.

[0019] Preferably, the strap is detachably connected to a protective pad, and the side of the protective pad facing the skin has a skin-friendly layer. The protective pad can prevent pressure sores on the cheeks. The position of the protective pad can be adjusted according to the possible location of pressure sores, or multiple protective pads can be added. It can also effectively maintain the winding direction of the strap, preventing the strap from shifting.

[0020] Preferably, the protective pad has a limiting band on the side away from the skin-friendly layer. One end of the limiting band is fixedly connected to the protective pad, and the other end of the limiting band can be attached to the surface of the protective pad. By using a wrapping tape to fix it, the position of the protective pad on the tape can be adjusted by contacting the limiting tape midway, allowing for multiple adjustments and reuse.

[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] like Figures 1 to 6 The non-invasive respiratory support and fixation kit shown includes a strap 1, a catheter 2, a nasal cannula 3, an attachment 4, and an adjustment structure.

[0030] The band 1 is made of medical silicone or a flexible material (such as cotton fabric). The catheter 2 is connected to the band 1 through the nasal cannula 3. The attachment 4 is placed on the catheter 2 and / or the nasal cannula 3. In this embodiment, the attachment 4 adopts a dressing or hydrocolloid dressing structure and is placed on the position of the catheter 2 corresponding to the forehead.

[0031] The adjustment structure includes a fixed base 5, a control button 6, a linkage component 7, and a locking component 8.

[0032] The control button 6 and the linkage component 7 are both located on the fixed base 5. The fixed base 5 is detachably connected to the belt body 1. The control button 6 moves to drive part of the belt body 1 to be stored in the fixed base 5. The locking element 8 is located at the control button 6 to limit the state of the control button 6.

[0033] The linkage assembly 7 includes a movable rod 70, a driven rod 71, a driving gear 72, a driven gear 73, and two take-up rods 74. The control button 6 is rotatably mounted on the fixed base 5. The movable rod 70 is located inside the fixed base 5 and connected to the control button 6. The driving gear 72 is connected to the movable rod 70. The driven rod 71 is rotatably mounted inside the fixed base 5. The driven gear 73 is connected to the driven rod 71 and meshes with the driving gear 72. The two take-up rods 74 simultaneously connect the part of the driven rod 71 that does not have the driven gear 73. The side wall of the fixed base 5 has an opening 50 and an outlet 51 through which the belt 1 can pass. The control button 6 is rotated to drive the two take-up rods 74 to wind the belt 1.

[0034] Regarding the connection method between the fixed seat 5 and the belt body 1, the fixed seat 5 is divided into two parts and then assembled and disassembled. That is, the fixed seat 5 is divided into a base 52 and a docking seat 53. The linkage component 7, the opening 50 and the outlet 51 are all located on the docking seat 53. The edge of the docking seat 53 is provided with multiple insertion pieces 54. The surface of the insertion pieces 54 is elastically set. The edge of the base 52 facing the docking seat 53 is provided with multiple insertion slots 55. The side of the base 52 facing the skin is provided with a skin-friendly surface 56.

[0035] To prevent the tape 1 from twisting and pressing on the skin when it is wound up, the base 52 is provided with pressure-relieving parts 57 at the positions of the opening 50 and the outlet 51. In this embodiment, the pressure-relieving parts 57 are flexibly designed.

[0036] The locking component 8 includes a locking button 80, a shaped rod 81, an anti-detachment plate 82, and a damping layer 83.

[0037] The irregular rod 81 is retractable on the side of the fixed base 5 where the control button 6 is located. The anti-detachment piece 82 is located at the end of the irregular rod 81 inside the fixed base 5. The locking button 80 is located at the end of the irregular rod 81 corresponding to the outside of the fixed base 5. The damping layer 83 is located on the surface of the irregular rod 81. The locking button 80 has multiple locking teeth 84 on the side facing the control button 6. The control button 6 has multiple limiting teeth 85 corresponding to the locking teeth 84 on its outer periphery.

[0038] Furthermore, to facilitate assembly and inspection of the winding of the belt 1, all components of the adjustment structure are made semi-transparent.

[0039] In addition, it can prevent pressure sores on the face, and to effectively maintain the position of the strap 1, the strap 1 is detachably connected to a protective pad 9, with a skin-friendly layer 90 on the side of the protective pad 9 facing the skin. The protective pad 9 can be directly attached to the side of the strap 1 corresponding to the skin, or it can be wrapped around the strap 1 and then placed on the cheek. In this embodiment, for easy reuse and quick adjustment, the strap 1 is wrapped around it for connection. That is, a limiting band 91 is provided on the side of the protective pad 9 away from the skin-friendly layer 90. One end of the limiting band 91 is fixedly connected to the protective pad 9, and the other end of the limiting band 91 can be attached to the surface of the protective pad 9.

[0040] During use, the fixing seat 5 and the belt body 1 are first assembled. Force is applied to separate the docking seat 53 and the base 52, so that the belt body 1 is inserted between the opening 50, the outlet 51 and the two winding rods 74 respectively. The docking seat 53 and the base 52 are then inserted and fixed together. During the insertion process, medical staff can see through the docking seat 53 whether the belt body 1 is placed correctly. If it is not accurate, it can be adjusted in time.

[0041] Next, the protective pad 9 and the band 1 are assembled. A portion of the band 1 is placed on the surface of the protective pad 9 away from the skin-friendly layer 90. The limiting band 91 is then flipped so that it wraps around the band 1 and adheres to the surface of the protective pad 9. In this embodiment, the attachment 4 is used in the same way as the protective pad 9. The portion of the band 1 corresponding to the forehead is connected to the attachment 4 using the same method. The band 1, together with the central nasal cannula 3, forms a ring structure. The upper part of the patient's head passes through the band 1, and the attachment 4 is attached to the patient's forehead. The band 1 now wraps around the head around the cheek, avoiding contact between the band 1 and the ear. The skin-friendly surface 56 of the fixing seat 5 and the skin-friendly layer 90 of the protective pad 9 are in contact with the patient's facial skin.

[0042] Finally, the tightness of the belt 1 needs to be adjusted according to the patient's face shape. First, apply force upwards to pull the locking button 80, temporarily releasing the locking state of the locking teeth 84 and the limiting teeth 85. At this time, the control button 6 can rotate without being rotated. Due to the meshing relationship between the driving gear 72 and the driven gear 73, while the control button 6 drives the moving rod 70 and the driving gear 72 to rotate, the driven gear 73 is also rotated under force. The driven gear 73 simultaneously drives the driven rod 71 to rotate, and also drives the two winding rods 74 to move around the center of the driven rod 71 as an axis. Figure 5 As shown, when the two take-up levers 74 move, they drive a portion of the belt 1 to be wound into the fixing seat 5. Furthermore, the fixing seat 5 is not limited to the position shown in this embodiment and can be positioned at any location on the belt 1. Similarly, rotating the control knob 6 in the opposite direction releases the belt 1, allowing adjustment of the overall tension of the belt 1 during winding or release.

[0043] After adjustment to the desired level, press the locking button 80 to re-engage the locking teeth 84 with the limiting teeth 85 of the control button 6. Due to the non-rotational restriction of the shaped rod 81, the current state of the control button 6 is restricted, that is, the winding state of the two winding rods 74 on the belt body 1 is maintained, thereby achieving the locking of the belt body 1 after adjustment.

[0044] The above description is a preferred embodiment of the present utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered within the protection scope of the present utility model.
