Description

Technical Field

[0001] This utility model belongs to the technical field of nasal negative pressure replacement beds, specifically involving an improved version of the nasal negative pressure replacement bed. Background Technology

[0002] Nasal negative pressure replacement is a common physical therapy method, mainly used to treat chronic sinusitis, excessive nasal secretions, and other diseases. This method generates intermittent negative pressure to introduce medication into the sinuses and suction out purulent secretions, thereby achieving the therapeutic goal. Currently, existing nasal negative pressure replacement treatments are usually performed on a regular examination bed or a simple table. During the treatment, the patient needs to lie flat and tilt their head back by placing a pillow under their shoulders to form a special head-lower-shoulder-elevated position. Medical staff then use a negative pressure suction device in conjunction with the medication. However, in actual use, because the patient needs to maintain a passive head-lower-shoulder-elevated position for a long time, the neck muscles need to continuously tense and exert force to overcome the weight of the head, which can easily lead to soreness and stiffness in the neck and shoulder muscles, and even dizziness and headaches. The patient's comfort is extremely poor, especially for children, whose resistance and twisting due to discomfort significantly increase the difficulty and risk of the operation. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide an improved nasal negative pressure replacement bed, which solves the problem of patients maintaining a passive position with their head lower than their shoulders for a long time. This position requires the neck muscles to exert continuous tension to overcome the weight of the head, which can easily lead to soreness and stiffness in the neck and shoulder muscles, and even dizziness and headaches.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an improved nasal negative pressure replacement bed, comprising a bed body with a lifting groove. A worm gear and a worm are housed inside the bed body. A screw is installed in the lifting groove and is keyed through the lifting groove to the worm gear. The worm gear meshes with the worm. A locking mechanism is provided on the screw, comprising a first clamp, a second clamp, a first rotation adjustment seat, a second rotation adjustment seat, a locking knob, and end face teeth. A support plate is provided on the locking mechanism to adjust and lock the pitch angle of the support plate relative to the screw axis. A Velcro strap and an angle measuring instrument are provided on the support plate, and the Velcro strap is adhesively connected to the adhesive layer on the pillow. The support plate and the pillow have rounded transitions on both sides.

[0005] The beneficial effects of this utility model are as follows: by adjusting the angle and height of the support plate and the pillow on it, the head can be supported when the patient is in a head-low and shoulder-high position, and the weight of the head can be distributed to the support plate and the pillow, thereby reducing the load on the neck muscles and improving the comfort of the neck and shoulders.

[0006] To facilitate adjustment of the height of the support plate and its upper cushion: As a further improvement to the above technical solution: the lifting groove is vertically opened below the head end of the bed, and the outer end of the first rotation adjustment seat of the locking mechanism is located in the lifting groove and connected to the screw, while the outer end of the second rotation adjustment seat of the locking mechanism is connected to the support plate.

[0007] The beneficial effects of this improvement are: when the screw rotates, it can drive the first rotating adjustment seat, drive the locking mechanism and its upper components to move up and down, and adjust the height of the support plate and its upper cushion.

[0008] To facilitate adjustment of the bracket plate's operating angle: As a further improvement to the above technical solution: the first clamp and the second clamp are disposed opposite to each other at the outer ends of the first and second rotation adjustment seats and are connected by a locking knob, wherein the first and second rotation adjustment seats are respectively located on both sides between the first and second clamps, and the first clamp is rotatably connected to the first and second rotation adjustment seats on both sides by a damping shaft.

[0009] The beneficial effect of this improvement is that by rotating the locking knob, the first and second rotating adjustment seats can be locked and released, so as to adjust the angle of the support plate.

[0010] To facilitate adjustment and fixation of the support plate's pitch angle: As a further improvement to the above technical solution: the inner walls of the first and second rotating adjustment seats near the second clamp and the opposite side of the second clamp are all provided with intermeshing end face teeth.

[0011] The beneficial effects of this improvement are as follows: After the locking knob drives the second clamp to press the first and second rotating adjustment seats together, the end face teeth on the inner wall of the second clamp can mesh with the end face teeth on the opposite rotating adjustment seat. Under the huge friction force generated by the meshing, the angle of the support plate is infinitely locked, and the position of the support plate is fixed so that the angle is not easily changed by the head pressure during treatment. When the locking knob is loosened, the pressing state of the second clamp on the first and second rotating adjustment seats can be released, so that the support plate can be rotated to adjust the pitch angle of the support plate.

[0012] To facilitate the installation and removal of the pillowcase: As a further improvement to the above technical solution: the Velcro is set on the top wall of the support plate, while the adhesive layer is set on the inner wall of the pillow, and the pillow is soft and elastic.

[0013] The beneficial effects of this improvement are as follows: after the Velcro and adhesive layer are bonded together, the pillow can be installed and fixed on the outer end of the support plate, so as to improve the comfort of the patient's head and neck support. Similarly, by reversing the operation to separate the Velcro and adhesive layer, the pillow can be removed for independent cleaning, disinfection or replacement.

[0014] To facilitate observation of the tilt angle of the support plate: As a further improvement to the above technical solution: the angle measuring instrument is embedded in the side wall of the support plate.

[0015] The beneficial effects of this improvement are: by setting up an angle measuring instrument, medical staff can intuitively and accurately display the current tilt angle of the support plate when adjusting the angle of use, so as to set or record the most comfortable and effective data angle for different patients, thereby improving the standardization and personalization of treatment.

[0016] To facilitate adjustment and locking of the operating height of the locking mechanism and its components: As a further improvement to the above technical solution: a turntable is rotatably provided at the outer end of the bed body, and the turntable is connected to one end of the worm gear located inside the bed body.

[0017] The beneficial effects of this improvement are as follows: by shaking the turntable to drive the worm to rotate, the self-locking and smoothness of the worm and worm wheel transmission can be utilized to control the worm wheel to drive the screw to rotate. The worm drives the locking mechanism and its components to perform lifting and lowering movements. When the worm stops rotating, the worm wheel and the screw connected to it will automatically lock, preventing the locking mechanism and its components from falling down by gravity.

[0018] In summary, the beneficial effects of this design are as follows: By adjusting the height and angle of the support plate and its pillow, the design supports the patient's head in a head-down, shoulder-up position, transferring the weight load on the patient's head from the vulnerable neck and shoulder muscles to a stable mechanical structure. This reduces soreness, stiffness, and related discomfort caused by continuous muscle tension. The height adjustment via the worm gear and worm drive pair utilizes its inherent self-locking characteristic to ensure that the lifting mechanism automatically locks at any height, preventing the support plate from accidentally sinking during treatment and ensuring the stability and safety of the treatment. The locking mechanism facilitates the adjustment and locking of the support plate's tilt angle to accommodate different patients' head tilts. The angle measuring instrument provides objective and accurate quantitative data for angle adjustment, allowing medical staff to quickly and accurately set and reproduce the optimal treatment angle. The detachable pillow facilitates cleaning, disinfection, or replacement, increasing the convenience of clinical maintenance.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0022] like Figure 1-6As shown, the improved nasal negative pressure replacement bed includes a bed body 1. The bed body 1 has a lifting groove 2. A worm gear 4 and a worm 5 are housed inside the bed body 1. A screw 3 is installed in the lifting groove 2, and the screw 3 passes through the lifting groove 2 and is keyed to the worm gear 4. The worm gear 4 is meshed with the worm 5. A locking mechanism 6 is provided on the screw 3. The locking mechanism 6 includes a first clamp 601, a second clamp 602, a first rotation adjustment seat 603, a second rotation adjustment seat 604, a locking knob 605, and end face teeth 606. A support plate 7 is provided on the locking mechanism 6 to adjust and lock the pitch angle of the support plate 7 relative to the axis of the screw 3. A Velcro 8 and an angle measuring instrument 9 are provided on the support plate 7. The Velcro 8 and the adhesive tape on the pillow pad 10 are... Layer 11 is bonded together. The support plate 7 and the pillow 10 have rounded transitions on both sides. By adjusting the angle and height of the support plate 7 and the pillow 10, the head can be supported when the patient is in a head-down, shoulder-up position, distributing the weight of the head to the support plate 7 and the pillow 10, thereby reducing the load on the neck muscles and improving neck and shoulder comfort. The lifting groove 2 is vertically opened below the head end of the bed frame 1, and the outer end of the first rotating adjustment seat 603 of the locking mechanism 6 is located in the lifting groove 2 and connected to the screw 3. The outer end of the second rotating adjustment seat 604 of the locking mechanism 6 is connected to the support plate 7. When the screw 3 rotates, it can drive the first rotating adjustment seat 603, which in turn drives the locking mechanism 6 and its components to move up and down, thus adjusting the position of the support plate 7 and the pillow 10. Height adjustment is achieved by using the first clamp 601 and the second clamp 602, which are positioned opposite each other at the outer ends of the first rotating adjustment seat 603 and the second rotating adjustment seat 604, and connected by a locking knob 605. The first rotating adjustment seat 603 and the second rotating adjustment seat 604 are located on opposite sides between the first clamp 601 and the second clamp 602, respectively. The first clamp 601 is rotatably connected to the first rotating adjustment seat 603 and the second adjustment seat on both sides via a damping shaft. By rotating the locking knob 605, the first rotating adjustment seat 603 and the second rotating adjustment seat 604 can be locked and released to adjust the angle of the support plate 7. The first rotating adjustment seat 603 and the second rotating adjustment seat 604 are located near the second clamp 602. Both the inner walls of the first clamp 602 and the second clamp 602 have interlocking end face teeth 606. By using the locking knob 605 to press the second clamp 602 against the first and second rotation adjustment seats 603 and 604, the end face teeth 606 on the inner wall of the second clamp 602 mesh with the end face teeth 606 on the opposite rotation adjustment seats. Under the enormous frictional force generated by this meshing, the angle of the support plate 7 is infinitely locked, fixing its position and preventing it from changing due to head pressure during treatment. Loosening the locking knob 605 releases the pressure of the second clamp 602 on the first and second rotation adjustment seats 603 and 604, allowing rotation to adjust the pitch angle of the support plate 7.The Velcro 8 is attached to the top wall of the support plate 7, while the adhesive layer 11 is attached to the inner wall of the pillow pad 10. The pillow pad 10 is soft and elastic. After the Velcro 8 and the adhesive layer 11 are bonded together, the pillow pad 10 can be fixed to the outer end of the support plate 7 to improve the comfort of supporting the patient's head and neck. Similarly, by reversing the operation to separate the Velcro 8 and the adhesive layer 11, the pillow pad 10 can be removed for independent cleaning, disinfection, or replacement. The angle measuring instrument 9 is embedded in the side wall of the support plate 7. The angle measuring instrument 9 allows medical staff to intuitively and accurately display the angle of the support plate 7 when adjusting its use angle. The current tilt angle of the plate 7 is adjusted to set or record the most comfortable and effective angle for different patients, improving the standardization and personalization of treatment. A turntable 12 is rotatably mounted on the outer end of the bed body 1, and the turntable 12 is connected to one end of a worm gear 5 located inside the bed body 1. By shaking the turntable 12, the worm gear 5 is driven to rotate. Utilizing the self-locking and smooth transmission between the worm gear 5 and the worm wheel 4, the worm wheel 4 is controlled to drive the screw 3 to rotate. The worm gear 5 drives the locking mechanism 6 and its components to move up and down. When the worm gear 5 stops rotating, the worm wheel 4 and the connected screw 3 automatically lock, preventing the locking mechanism 6 and its components from falling under gravity.

[0023] The working principle of this utility model is as follows: In the initial state, medical staff rotate the turntable 12 located outside the bed body 1. Power is transmitted through the turntable 12 to the worm gear 5 fixed to it. The rotation of the worm gear 5 drives the worm wheel 4 meshing with it to rotate, causing the screw 3 connected to the worm wheel 4 to rotate in the lifting groove 2, and driving the locking mechanism 6 and its components connected to it to perform lifting and lowering movements, so as to adjust the height of the support plate 7 according to the support requirements. When the locking knob 605 of the locking mechanism 6 is loosened, the clamping force of the second clamp 602 on the first rotation adjustment seat 603 and the second rotation adjustment seat 604 is released, so that the end face teeth 606 respectively set on their opposite surfaces are disengaged. At this time, the support plate 7 can rotate around the locking mechanism 6. During the rotation adjustment, medical staff can refer to the reading of the angle measuring instrument 9 to adjust the support plate 7 and the pillow 10, which is bonded to the adhesive layer 11 via Velcro 8, to the optimal pitch angle that conforms to the patient's physiological curvature. After the angle is determined, the locking knob 605 is turned in the opposite direction to push the second clamp 602 against the rotation adjustment seat, forcing the end face teeth 606 to re-engage tightly. The huge frictional torque generated by the engagement of the end face teeth 606 can be used to achieve rigid locking of the pitch angle of the support plate 7, so as to support the patient's head tilted back during treatment. When the patient's head rests on the curved transition pillow 10, the weight of the head is distributed, the neck and shoulder muscles are released, and the comfort of maintaining the position is improved.
