Description

Technical Field

[0001] The present invention relates to the technical field of instruments and appliances, and in particular to an inflatable prone facial decompression device. Background Art

[0002] During prone surgeries such as thoracic and lumbar surgeries and posterior cranial surgeries, the patient's face is under continuous gravity pressure, especially the forehead and mandible as the main support points, which are prone to pressure injuries (such as pressure sores and nerve paralysis). Traditional support devices have the following defects, such as static compression risks, blind spots in disinfectant control, respiratory safety shortcomings, and lack of posture adjustment. During medical treatment operations, depending on the requirements of the surgical site and surgical method, such as surgery on the thoracic and lumbar spine or the back of the head, the patient is positioned prone during surgery. The head will exert considerable pressure on the face due to gravity. If the operation is long and the surgical position cannot be fine-tuned, the forehead and mandible as support points will be under pressure for a long time, causing pressure damage to the patient's facial skin. On the other hand, when medical staff disinfect the patient's head wound, the disinfectant may flow into the patient's eyes, causing eye burns.

[0003] Therefore, in response to the above problems, a new inflatable prone facial decompression device is proposed. Summary of the Invention

[0010] Furthermore, a three-way groove is provided at the top end of the adjustment seat, and a single-way groove is provided at the bottom end of the adjustment seat, which respectively correspond to the cheek airbag and the forehead airbag.

[0011] Furthermore, the buffer deflation structure includes a sleeve fixedly mounted on the bottom end of the conduit, a piston is slidably connected to the interior of the sleeve, a limiting spring is provided inside the sleeve, and one end of the limiting spring is cooperatively connected to the piston, an air outlet pipe is fixedly mounted on the bottom end of the sleeve, and an electromagnetic valve is provided at the connecting end of the sleeve and the conduit.

[0015] The technical solution provided by the present invention can have the following beneficial effects: 1. The filter mechanism of the present invention adopts a sliding plug-in design. It is fixed with the limiting block inside the support body through an L-shaped plug-in frame, forming a sealed protective cover that completely covers the ventilation groove. The internal filter can effectively intercept particulates in the air to prevent patients from inhaling foreign matter. The modular design supports quick disassembly, facilitating cleaning or replacement of the filter, ensuring long-term filtration efficiency. The built-in support ring strengthens the structural strength of the limiting block, making it durable and solving the problem of component deformation caused by frequent disassembly and assembly, providing patients with stable and reliable breathing safety. 2. The swing mechanism of the present invention provides multi-level angle adjustment through the convex-groove meshing structure of the connecting seat and the support seat. Clinicians can precisely adjust the support body at small angles (such as slight left and right tilt) according to the patient's needs to optimize the head position. After adjustment, the convex-concave structure automatically locks, effectively preventing accidental displacement during surgery. This design not only meets the needs of personalized body position adjustment, but also ensures absolute stability of the device during treatment, reduces neck pressure, and improves tolerance to long-term prone position. 3. The airbag support mechanism of the present invention uses an electromagnet to drive the adjustment seat, achieving independent inflation and deflation control of the forehead and cheek airbags, and precise zoning pressure regulation: the single-way / three-way slot design of the adjustment seat allows selective inflation of the forehead or cheek areas, targeted relief of local pressure points (such as the cheekbones and forehead), and avoids discomfort caused by uniform pressure; cyclic pressure cycling: the preset inflation and deflation program causes the airbag to alternate between a "support state" and a "flexible state", periodically shifting pressure points, promoting blood circulation, simulating natural micro-movements, and significantly reducing the risk of pressure ulcers; airflow-assisted comfort: the rubber strips on the surface of the forehead and cheek airbags reduce the skin contact area, and the internal air delivery grooves and strip grooves form a directional airflow channel, accelerating sweat evaporation and alleviating stuffiness; air pressure triggers the cover plate to move and release micro-airflow, further enhancing the heat dissipation effect; 4. The present invention adopts oblique groove flow control technology during the deflation process: the gradually inclined groove with shallow depth at the top and deep depth at the bottom of the sleeve inner wall is linked to the piston. In the initial stage, the groove body is not exposed (zero flow), and the ventilation cross-section is gradually increased as the piston moves downward. This design forces the deflation rate to increase slowly from zero, avoiding the instantaneous tissue rebound discomfort caused by the sudden drop in internal pressure of the airbag. The limiting spring provides controllable resistance, and the solenoid valve ensures sealing during inflation, together realizing the humanized operating experience of "fast charging and slow deflation".

[0033] Specifically, the buffer adjustment mechanism includes a rubber strip 31 fixedly installed at equal intervals on the surface of the forehead airbag 15, and an air delivery groove 32 is provided inside the rubber strip 31.

[0034] Specifically, strip-shaped grooves are equidistantly provided on the surface of the rubber strip 31 and are interconnected with the through holes on the rubber strip 31 to form an air passage.

[0035] In this embodiment, in order to increase the patient's facial comfort and breathing comfort when the patient adopts the prone position, reference is made to Figures 1 to 4 The specific implementation is as follows: the top of the support body 1 is designed with a facial depression 2 that matches the patient's facial contour and is used to stably support the patient's head. To ensure the patient's breathing is smooth when in a prone position, a special ventilation groove 3 is provided at the bottom of the support body 1. To prevent tiny foreign matter or particles from being inhaled by the patient through the ventilation groove 3 and causing discomfort, an air filter mechanism 4 is installed at the position of the ventilation groove 3. To ensure continuous and effective filtering efficiency and facilitate maintenance, the filter mechanism 4 is designed to be a detachable structure. During specific operation, the plug-in frame 7 can be removed from the support body 1, and then the internal filter 9 can be cleaned or replaced to ensure that the filter mechanism 4 remains in the best clean state during subsequent use. In terms of installation convenience, the filter mechanism 4 is snapped into place with the symmetrically arranged limiting blocks 11 inside the support body 1 through the plug-in frames 7 on both sides, achieving quick and stable installation. In particular, the two symmetrical plug-in frames 7 together form a complete protective cover after being installed in place, completely covering the ventilation groove 3, effectively blocking external impurities and preventing them from being inhaled by the patient.

[0036] It should be noted that: in order to enhance the deformation resistance of the limiting block 11 under long-term and frequent disassembly and assembly conditions and ensure a long-lasting and stable clamping effect, a support ring 12 is integrated inside it. The support ring 12 provides rigid support for the core structure and effectively resists the elastic attenuation caused by material fatigue, thereby ensuring a long-term and stable cooperation relationship between the filter mechanism 4 and the support body 1.

[0037] In this embodiment, in order to increase the patient's prone position, the patient's head can be rotated in a small range according to actual needs. Figure 5 The specific implementation is as follows: when fine-tuning of the head is required according to clinical operation or patient comfort requirements, it can be achieved by adjusting the relative angle between the support base 13 and the connecting base 14. The two are connected and locked using an innovative bump-groove engagement structure. This design allows angle adjustment in multiple preset gears and provides reliable mechanical locking after the angle is selected. The locking mechanism effectively prevents accidental displacement of the support body 1 during use, significantly improves the stability of the overall device, and thus provides more stable and precise support for the patient's head.

[0038] In this embodiment, in order to further increase the comfort of the patient when using the device, an airbag support mechanism 6 is installed on the facial concave area 2, which can adjust the patient's facial support position in real time during use. Figures 6 to 8 The specific implementation method is as follows: during patient use, gas from an external gas source is transported through the gas supply tube 25, passes through the one-way valve 24, the catheter 23, the mounting seat 19 and the adjustment seat 21 in sequence, and is finally injected into the forehead and parietal airbags 15 and / or the cheek airbags 16. The key point is that the system can accurately control the axial displacement of the adjustment seat 21 through the electromagnet 20 according to clinical needs or patient comfort feedback. This adjustment mechanism realizes the active selection of the inflation path, so that the forehead and parietal airbags 15 or the cheek airbags 16 can be inflated preferentially or independently. Through this differentiated inflation strategy, the device can provide customized flexible support for specific areas of the patient's face (such as the forehead or cheeks), thereby dynamically optimizing the facial pressure distribution and significantly improving the patient's overall comfort in the prone position.

[0039] Controlled deflation and cushioning mechanism: When the forehead airbag 15 or the cheek airbag 16 is deflated, the electromagnet 20 can also be used to drive the adjustment seat 21 to adjust the position to achieve selective deflation path control. This allows the target airbag (such as the forehead or unilateral cheek area) to be deflated first, avoiding the simultaneous rapid decompression of all airbags, which may cause discomfort to the patient.

[0040] The released gas is first guided into the sleeve 26, and the gas pressure acts on the piston 27, overcoming the elastic force of the limiting spring 28 and pushing the piston 27 downward. During this downward process, the piston 27 gradually reveals the preset oblique groove 30 on the inner wall of the sleeve 26. The key design is that the depth of the oblique groove 30 is gradually distributed from shallow at the top to deep at the bottom along the movement direction of the piston 27.

[0041] Initial stage (piston 27 at high position): the piston 27 does not expose the shallowest upper portion of the oblique groove 30 , the gas flow cross-sectional area is zero, and the degassing is restricted.

[0042] Progressive stage (piston 27 moves downward): As the piston 27 continues to move downward, the depth of the exposed oblique groove 30 and the effective flow area increase synchronously, and the degassing rate increases gradually.

[0043] The core function of this shallow-to-deep gradient groove design is to actively delay the initial deflation rate and achieve gradual and controllable pressure relief. It effectively prevents the sudden drop in pressure caused by the instantaneous rapid emptying of gas in the airbag, eliminates the discomfort in the patient's forehead or cheeks that may be caused by this, and significantly improves the comfort of the decompression process.

[0044] Supplementary explanation: The solenoid valve 37 provided at the connection between the sleeve 26 and the conduit 23 remains closed during the airbag inflation phase to ensure that gas does not leak through the sleeve 26 path, thereby ensuring the inflation efficiency and the reliability of pressure establishment.

[0045] In this embodiment, in order to further improve the comfort of the patient during use, the surface of the forehead airbag 15 is also provided with a buffer adjustment structure. Figure 9 The specific implementation is as follows: the surface of the forehead airbag 15 is integrated with a number of parallel rubber strips 31, achieving dual optimization goals: Minimizing the contact area: significantly reducing the direct contact area between the patient's forehead skin and the airbag surface, which not only effectively disperses local pressure, but also reduces the discomfort that may be caused by long-term compression; Maximizing air circulation space: A continuous air circulation channel is naturally formed between the skin and the airbag surface, which greatly promotes sweat evaporation and heat dissipation, significantly alleviating the discomfort caused by hot and humid skin. During the airbag inflation process, part of the gas is introduced into the air delivery groove 32 inside the rubber strip 31. As the internal air pressure increases, the gas acts on the cover plate 35, overcoming the preload force of the auxiliary spring 36, pushing the cover plate 35 and the connected mounting rod 34 upward (away from the airbag surface) to generate axial displacement. The cover plate 35 is removed from the central through hole of the mounting plate 33, exposing the through hole, and the pressurized gas inside the rubber strip 31 can pass. The exposed through-holes actively release the gas, and the released gas does not escape disorderly, but flows in a directed manner along the precisely designed strip grooves (forming a preset flow channel) on the surface of the rubber strip 31. This controllable, skin-close micro-airflow further enhances the contact and heat exchange efficiency between the skin surface and the air. The rubber strip 31 and its integrated dynamic airflow system together constitute an active surface ventilation and pressure management interface. It significantly improves the contact comfort and dryness of the patient's forehead area through a two-pronged approach through physical contact relief and actively guided local airflow circulation. It is particularly suitable for clinical scenarios where the prone position needs to be maintained for a long time.

[0046] It should be noted that the system can be configured to perform a preset period of inflation and deflation cycle on the airbag support mechanism 6. This operation drives the forehead airbag 15 and the cheek airbag 16 to regularly alternate between a full support state (providing maximum support height and contact pressure) and a semi-air flexible support state (significantly reducing support height and pressure, and presenting high flexibility). This dynamic pressure regulation mechanism effectively alleviates tissue fatigue caused by continuous compression by periodically shifting the pressure points in the forehead and cheek areas, promotes local blood perfusion, and simulates physiological micro-motion stimulation, thereby significantly reducing tissue compression discomfort caused by prolonged prone position and improving the patient's overall comfort and tolerance.
