Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to a ventilator trachea fixator. Background Art

[0002] As an important life support device, ventilators are widely used in scenarios such as intensive care, surgical anesthesia, and home care. The fixation device of the ventilator trachea is a key component to ensure the normal operation of the device and the safety of patients. However, most of the currently clinically used ventilator trachea fixation devices adopt a fixed structure, and the trachea is directly fixed at a specific position on the patient's face through tapes or straps. This fixation method has significant defects: since the position of the trachea cannot be flexibly adjusted, long-term fixation is likely to cause muscle fatigue around the patient's mouth or local skin compression damage. Especially for patients who need to use a ventilator for a long time, their comfort and safety are difficult to be effectively guaranteed. In addition, the traditional fixation method requires re-dismantling and pasting when adjusting the position of the trachea, which is cumbersome to operate and easy to cause contamination, increasing the workload of medical staff and possibly leading to an increase in the risk of infection. Summary of the Invention

[0003] In view of the technical defects of the existing ventilator trachea fixation devices, such as non-adjustable fixation position, discomfort caused by long-term single-point compression to patients, and cumbersome operation, the present invention provides an improved ventilator trachea fixator. The fixator realizes flexible adjustment and stable locking of the position of the ventilator trachea through the sliding adjustment mechanism and quick locking structure of the slide rail and the slider, and significantly improves the safety and comfort in clinical use.

[0004] The present invention provides a ventilator trachea fixator, which includes a baseband, a slide rail, a slider, a trachea holder, and a locking structure. Among them, the baseband is the basic structure of the entire device, and fixing holes are provided at both ends for connecting binding straps to fix the fixator to the patient's face; a slide rail and several card slots are provided along the length direction of the baseband. The slide rail is used for the sliding of the slider, and the card slots are used to lock the position of the slider. Further, the slide rail extends along the length direction of the baseband and is fixedly connected to the baseband. Its cross-section is T-shaped and matches the slider to ensure the stable sliding of the slider on the slide rail. In particular, the slider is a non-closed rectangular ring structure with a notch, which matches the cross-section of the slide rail to ensure smooth sliding and not easy to break away.

[0005] The trachea holder is fixed to the slider and is a non-closed elastic tubular structure with a trachea insertion notch for clamping the ventilator trachea. Further, the trachea holder and the baseband are arranged in a staggered and crossed manner to reduce the direct compression on the patient's face and improve the wearing comfort; the elastic tubular structure can adapt to tracheas of different diameters and has strong versatility. In particular, the trachea holder is fixedly connected to the pressing static handle and thus fixed to the slider.

[0006] The locking structure includes a static pressing handle, a movable pressing handle, a movable seat and teeth. Among them, the static pressing handle is fixed to the slider, one end of the movable pressing handle is elastically connected to the static pressing handle, and the other end is a free pressing end; the movable seat is connected to the part of the movable pressing handle away from the free pressing end, and is provided with two teeth distributed in a V shape, which are respectively connected to the left and right sides of the movable seat and cooperate with the card slots on the base belt to lock the position of the slider. When the movable pressing handle is released, the teeth are inserted into the corresponding card slots; when the movable pressing handle is pressed towards the static pressing handle, the movable seat drives the teeth to disengage from the card slots, thereby realizing unlocking.

[0007] Furthermore, an air tube strap is arranged on the static pressing handle to assist in fixing the ventilator tube and prevent the tube from slipping off. Particularly, the tube clamp, the static pressing handle, the movable pressing handle, the movable seat, the teeth and the slider can be integrally injection-molded, which simplifies the manufacturing process and improves the structural strength.

[0008] The beneficial effects of the present invention are achieved through the following technical solutions: First, the sliding fit structure of the slide rail and the slider enables medical staff to easily adjust the fixing position of the ventilator tube by moving the slider, avoiding muscle fatigue or skin damage caused by long-term single-point compression. Second, the design of the locking structure can quickly fix the position of the slider to ensure the stability of the tube; the press-to-unlock design simplifies the adjustment process and the position can be adjusted without disassembling the device. Third, the base belt and the tube clamp are arranged in a staggered and crossed manner, reducing the direct pressure on the patient's face. At the same time, the elastic tubular tube clamp can adapt to tubes of different diameters, enhancing the versatility. Finally, the overall structure is reasonably designed, easy to operate and highly stable, significantly improving the safety and convenience of clinical use.

[0009] Particularly, the present invention solves the problem of cumbersome operation of the traditional ventilator tube fixing device through a specific implementation method. The ventilator tube is inserted into the tube clamp and is assisted to be fixed to the static pressing handle by the air tube strap; the movable pressing handle is pressed towards the static pressing handle to drive the movable seat to move, so that the teeth disengage from the card slots, realizing the unlocking of the locking structure; the slider is moved left and right along the slide rail to adjust the left and right positions of the ventilator tube, avoiding muscle fatigue damage caused by long-term fixation at one position in the oral cavity; after the adjustment is in place, the movable pressing handle is released, and the teeth are inserted into the current corresponding card slots to realize the position locking of the ventilator tube again.

[0010] Through the above technical solutions, the present invention not only solves many problems existing in the traditional ventilator tube fixing device, but also significantly improves the safety and comfort of clinical use, and has important practical value and popularization prospects.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0019] The present invention provides a ventilator trachea fixator, and the detailed implementation manners will be described with reference to Figure 1 to Figure 5 For the detailed description. The ventilator trachea fixator includes a baseband 1, a slide rail 2, a slider 4, a trachea card holder 12, and a locking structure. The functions and connection relationships of each component achieve operational simplicity and clinical use reliability through reasonable structural design in actual applications.

[0020] The baseband 1 is the basic structure of the whole device. Fixed holes 11 are provided at both ends of it, which are used to fix the device to the patient's face through a binding strap. The baseband 1 is made of a flexible material, which can closely fit the contour of the patient's face while avoiding excessive pressure on the skin. The slide rail 2 is fixedly connected to the baseband 1 and extends along the length direction of the baseband 1. The cross-section of the slide rail 2 is T-shaped, which matches the slider 4 to ensure the stable sliding of the slider 4 on the slide rail 2. The material of the slide rail 2 is selected from high-strength plastics or metal materials, which have sufficient rigidity to bear the weight of the slider 4 and the components carried thereon and the forces during use. At the same time, the surface is smooth-treated to reduce the frictional resistance and facilitate the movement and adjustment of the slider 4.

[0021] The slider 4 is a non-closed rectangular ring structure with a notch. The inner shape thereof matches the T-shaped cross-section of the slide rail 2 to ensure that the slider 4 can slide smoothly on the slide rail 2 and is not easily detached. Mounting interfaces are provided on the outer side of the slider 4 for fixing the pressing static handle 9 and other components connected thereto. The design of the slider 4 enables it to cooperate firmly with the slide rail 2 and will not loosen or fall off due to long-term use.

[0022] The trachea holder 12 is fixed on the slider 4 and is a non-closed elastic tubular structure with a trachea clamping notch, which is used to clamp the ventilator trachea. The elastic characteristic of the trachea holder 12 enables it to adapt to ventilator tracheas of different diameters, with a wide range of applications. The trachea holder 12 and the baseband 1 are arranged in a staggered and crossed manner, and this arrangement reduces the direct pressure on the patient's face and improves the wearing comfort. The material of the trachea holder 12 is selected from medical-grade silicone or other elastic materials, which have good flexibility and durability, can maintain a stable shape for a long time, and avoid damaging the ventilator trachea.

[0023] The locking structure includes a pressing static handle 9, a pressing moving handle 8, a movable seat 5 and teeth. The pressing static handle 9 is fixed on the slider 4, and a trachea binding strap 10 is arranged thereon, which is used to assist in fixing the ventilator trachea to prevent the trachea from slipping off. One end of the pressing moving handle 8 is connected to the pressing static handle 9 through an elastic connecting piece, and the other end is a pressing free end. The movable seat 5 is connected to the part of the pressing moving handle 8 away from the pressing free end, and two teeth distributed in a V-shaped manner are arranged, namely a first tooth 6 and a second tooth 7, which are respectively connected to the left and right sides of the movable seat 5. The teeth cooperate with the card slots 3 on the baseband 1 to realize the locking of the position of the slider 4.

[0024] When it is necessary to adjust the position of the ventilator trachea, medical staff press the pressing handle 8 in the direction close to the static pressing handle 9, driving the movable seat 5 to move, so that the first cogs 6 and the second cogs 7 disengage from the card slots 3, thus unlocking the locking structure. At this time, the slider 4 can move left and right along the slide rail 2 to adjust the left and right positions of the ventilator trachea, avoiding muscle fatigue damage caused by long-term fixation in one position in the oral cavity. After the adjustment is in place, release the pressing handle 8, and the first cogs 6 and the second cogs 7 automatically snap into the current corresponding card slots 3 under the action of elasticity, locking the position of the ventilator trachea again. The design of the locking structure enables the adjustment process without disassembling the device, with simple and reliable operation.

[0025] In order to further simplify the manufacturing process and improve the structural strength, the trachea holder 12, the static pressing handle 9, the pressing handle 8, the movable seat 5, the cogs and the slider 4 can be manufactured by using the integral injection molding technology. This manufacturing method not only reduces the production cost, but also improves the connection strength between components, reducing the risk of component loosening or damage caused by long-term use.

[0026] In the actual use process, the operation process of the ventilator trachea fixator is as follows: S1: Clip the ventilator trachea into the trachea holder 12 and assist in fixing it to the static pressing handle 9 through the trachea strap 10; S2: Press the pressing handle 8 in the direction close to the static pressing handle 9, driving the movable seat 5 to move, so that the first cogs 6 and the second cogs 7 disengage from the card slots 3, realizing the unlocking of the locking structure; S3: Move the slider 4 left and right along the slide rail 2 to adjust the left and right positions of the ventilator trachea, avoiding muscle fatigue damage caused by long-term fixation in one position in the oral cavity; S4: After the adjustment is in place, release the pressing handle 8, and the first cogs 6 and the second cogs 7 automatically snap into the current corresponding card slots 3 under the action of elasticity, locking the position of the ventilator trachea again.

[0027] The design of this ventilator trachea fixator solves many problems existing in traditional fixing devices. First of all, the sliding fit structure of the slide rail 2 and the slider 4 enables medical staff to easily adjust the fixing position of the ventilator trachea by moving the slider 4, avoiding muscle fatigue or skin damage caused by long-term single-point compression. Secondly, the design of the locking structure can quickly fix the position of the slider 4 to ensure the stability of the trachea; the pressing and unlocking design simplifies the adjustment process and the position adjustment can be completed without disassembling the device. Thirdly, the base belt 1 and the trachea holder 12 are arranged in a staggered and crossed manner, reducing the direct pressure on the patient's face. At the same time, the elastic tubular trachea holder 12 can adapt to tracheas of different diameters, enhancing the versatility. Finally, the overall structure is reasonably designed, with simple operation and high stability, significantly improving the safety and convenience of clinical use.

[0028] In specific application scenarios, this ventilator trachea fixator is applicable to various types of patients, including adults and children. For patients using a ventilator for a long time, medical staff can flexibly adjust the position of the trachea according to the specific needs of the patients, reducing the discomfort caused by local compression. In addition, the design of the elastic tubular trachea holder 12 enables this device to adapt to different models of ventilator tracheas without the need to replace additional accessories, further enhancing the practicality and economy of the device.

[0029] In summary, the ventilator trachea fixator provided by the present invention realizes flexible adjustment and stable locking of the position of the ventilator trachea through innovative structural design and technical solutions, solves many problems existing in traditional fixing devices, and significantly improves the safety and comfort of clinical use. The structural design of this device is reasonable and the operation is simple, having important practical value and popularization prospects.
