Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically to a head dressing change auxiliary support device. Background Technology

[0002] In neurosurgical clinical nursing, dressing changes are a frequent procedure for patients with head trauma or after surgery. Existing dressing change methods and auxiliary devices have the following core problems: First, the current mainstream method is for medical staff / family members to manually support the patient's head or let the patient lie directly on a regular pillow. The former is labor-intensive and the patient's head is prone to shaking due to fatigue, which increases the patient's wound pain. The latter cannot fix the head position, and the dressing solution is prone to seeping into the pillow and soiling the sheets during dressing changes. In addition, the patient's neck is suspended in the air, which can easily cause discomfort. In existing technologies, some devices (such as folding support plates) can only provide support at a single angle and lack height adjustment functions, making them unsuitable for patients of different heights and positions. Some dressing aids are functionally limited and lack a liquid collection structure, failing to address the issue of medication contamination. For example, Chinese Patent Publication No. CN221106308U discloses a device for facilitating head dressing changes in comatose patients. Although it achieves multi-directional adjustment through telescopic devices and universal ball joints, and adds a neck support and lighting components, it has the following limitations: 1. The fixing method is a "clamp-type" that needs to be clipped onto the bed frame, making it unsuitable for non-bedridden patients (such as those in a semi-recumbent position) or scenarios without standard bed frames (such as outpatient dressing chairs); 2. It lacks a liquid collection function, making it impossible to prevent medication contamination of clothing or sheets during dressing changes; 3. The integrated Bluetooth-controlled lighting components have a relatively complex structure and high manufacturing costs, and the need for "intelligent lighting" during clinical dressing changes is not a core pain point.

[0003] In summary, existing technologies lack a head dressing assistance device that is simple in structure, flexible in adjustment, and can balance fluid collection with patient comfort, and targeted improvements are urgently needed. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable head dressing change auxiliary support device that is structurally simplified, reduces costs and failure rates, is easy to operate, integrates liquid collection functions, avoids drug contamination, and reduces subsequent cleaning work in order to overcome the shortcomings of existing technologies.

[0005] The present invention achieves the above objectives by adopting the following technical solution: an adjustable head dressing change auxiliary support device, characterized in that it includes a base, a height adjustment mechanism, and an angle adjustment plate, wherein the height adjustment mechanism is fixed on the base and is used to adjust the overall support height of the device;

[0006] The angle-adjustable support plate includes a support plate and a universal joint. The support plate is detachably connected to the top of the height adjustment mechanism via the universal joint. The universal joint is provided with an angle locking knob for fixing the angle of the support plate after adjustment. The angle-adjustable support plate is provided with a neck groove for supporting the patient's neck and an arc-shaped headrest adapted to the curvature of the back of the human head.

[0007] The tray is equipped with a liquid collection component to collect medication, cleaning fluid, or pus and blood generated during dressing changes.

[0008] As a further explanation of the above solution, the liquid collection component is connected to a liquid storage box, which is a pull-out structure and is detachably embedded in the bottom of the liquid collection component. The liquid storage box has a capacity of 300-500ml and volume scale lines are provided on the outside of the box.

[0009] Furthermore, the liquid collection assembly is connected to the lower surface of the angle adjustment tray via a snap-fit ​​or sliding groove structure, with a groove depth of 3-5cm and an opening width of 8-12cm.

[0010] Furthermore, the height adjustment mechanism includes a telescopic rod and a locking knob. The telescopic rod is a segmented sleeve structure, and the locking knob is used to tighten or loosen adjacent sleeves. Alternatively, the height adjustment mechanism includes a sleeve and pin holes. At least three pin holes are spaced axially on the side wall of the sleeve, and the height is fixed by inserting pins into different pin holes.

[0011] Furthermore, the inner arc surface of the arc-shaped headrest has an arc radius of R10-R15cm, and a medical silicone pad or a medical sponge pad is attached to the inner arc surface, the pad having a thickness of 0.5-1cm.

[0012] Furthermore, a breathable medical sponge pad is attached to the inner wall of the neck groove, and the surface of the sponge pad is covered with waterproof non-woven fabric.

[0013] Furthermore, the liquid collection component is a disposable integrated collection structure, including a waterproof paper collection pad and a fixing clip; the fixing clip is located at one end edge of the angle adjustment tray near the neck groove, and is used to fix the waterproof paper collection pad, which can be directly discarded after use.

[0014] Furthermore, the outer wall of the height adjustment mechanism is detachably connected to a flexible universal hose via an annular sleeve, and an LED lighting component is installed at the top of the hose. The illumination angle of the lighting component can be adjusted by bending the hose.

[0015] The beneficial effects that this utility model can achieve by adopting the above-mentioned technical solution are:

[0016] 1. This utility model adopts a head dressing change auxiliary support structure mainly composed of a base, a height adjustment mechanism, and an angle adjustment tray. Through the height adjustment mechanism and universal joint, the support height and angle can be accurately and quickly adjusted, which can easily adapt to various body positions such as lying flat and lying on the side, ensuring that the head is in the most stable position for dressing change.

[0017] 2. This utility model integrates liquid collection, which can effectively collect the medicine, pus, blood or cleaning fluid that flows down during dressing changes, avoiding contamination of bed sheets, pillows and patient clothing, reducing subsequent cleaning work and improving the cleanliness of the operating table.

[0018] 3. Simple structure and strong practicality: The core components are all mechanical structures (telescopic rod, universal joint, collection tank), without complex circuits or pneumatic components, which reduces manufacturing costs and failure rate, making it very suitable for clinical promotion.

[0019] 4. Improve patient comfort: The neck groove and curved headrest are ergonomically designed to provide even and comfortable support for the patient's head and neck, reducing discomfort during dressing changes. Attached Figure Description

[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of this utility model clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figures 1-2 As shown, this utility model is an adjustable head dressing change auxiliary support device, including a base 1, a height adjustment mechanism 2, an angle adjustment support plate 3, and a liquid collection component 4. The base 1 is a flat, rigid structure, generally made of stainless steel or ABS plastic, providing stable support for the entire device. It can be placed directly on the surface of a hospital bed, dressing chair, or treatment table without relying on a bed frame for fixation, making it suitable for use in multiple scenarios.

[0029] The height adjustment mechanism 2 is vertically fixed to the center of the upper surface of the base 1. It adopts a mechanical structure of telescopic rod + locking knob. The telescopic rod is multi-segmented with a travel range of 15-30cm, allowing adjustment of the overall height according to the patient's position. For example, lower support is needed when lying flat, and higher support is needed when in a semi-reclining position. After adjustment, the locking knob is used to lock the position and ensure stable support. It is worth noting that the height adjustment mechanism can also adopt a mechanical structure of sleeve + pin holes. The sleeve sidewall has at least three pin holes spaced axially, and the height is fixed by inserting pins into different pin holes. Of course, cylinder-driven lifting and adjustment is also possible, but since cylinder-driven methods are more common, they will not be elaborated here. The outer sidewall of the height adjustment mechanism is detachably connected to a flexible universal hose via a ring sleeve. An LED lighting component is installed at the top of the hose, and the illumination angle of the lighting component can be adjusted by bending the hose.

[0030] The angle-adjustable support plate 3 includes a support plate 3-1 and a universal joint 3-2. The support plate is connected to the top of the height adjustment mechanism via the universal joint and the corresponding support arm 3-3. The universal joint is equipped with a locking knob, which can adjust the angle of the support plate 360° (e.g., the support plate tilts 10-15° when lying flat, and 30-45° when lying on the side). After adjustment, it is locked to keep the head stable. Since the universal joint is a purchased product, its specific structure will not be described in detail here. The support plate 3-1 has a neck groove 3-11 in the middle, which conforms to the physiological curve of the neck and prevents the neck from being suspended. The upper part is equipped with an arc-shaped headrest 3-12 that is adapted to the curvature of the back of the human head (R10-R15cm). The inner silicone / sponge pad is lined to distribute the pressure on the head and reduce the pressure on the wound.

[0031] The liquid collection component 4 is detachably connected to the lower end of the tray near the neck groove (the medication naturally flows to this end during dressing changes). The liquid collection component 4 is a U-shaped collection trough connected to a storage box 5. The storage box 5 is a pull-out structure and is detachably embedded in the bottom of the liquid collection component. The U-shaped collection trough is connected to the tray via a snap-fit / sliding groove, allowing for quick disassembly and cleaning. The storage box has a capacity of 300-500ml and is marked with graduations for easy observation of the medication volume. After use, it can be pulled out, emptied, and cleaned. For outpatient quick dressing changes, it can also be replaced with a disposable waterproof collection pad, secured by a snap-fit ​​edge, disposable after use, and prevents cross-infection.

[0032] Taking postoperative dressing changes for a patient lying flat on their head as an example, the specific steps are as follows:

[0033] A. Device Placement: Place the base stably on the side of the patient's pillow on the bed, ensuring that the base is not tilted;

[0034] B. Height Adjustment: Loosen the locking knob of the height adjustment mechanism, extend the telescopic rod to 25cm (adapt to the head support height of a lying patient), and tighten the knob to lock the height;

[0035] C. Angle Adjustment: Loosen the locking bolt of the universal joint, tilt the angle adjustment plate 15° (so that the head is tilted slightly downward to facilitate the flow of the medicine to the collection component), and tighten the bolt to fix the angle;

[0036] D. Patient positioning: Gently lift the patient's head and place their neck into the neck groove (sponge pad fits the neck), with the back of the head resting on the curved headrest (silicone pad contacts the skin to reduce friction).

[0037] E. Liquid collection preparation: Check whether the buckle connection between the U-shaped collection tank and the tray is secure, and confirm that the liquid storage box is completely embedded in the bottom of the tank;

[0038] F. Dressing Change Procedure: Medical staff disinfect the wound and change the dressing. During the dressing change, the medicine and cleaning solution generated flow along the surface of the tray into the U-shaped collection trough and finally converge into the storage box.

[0039] G. Follow-up processing: After the dressing change is completed, gently remove the device, pull out the reservoir to pour out the medicine, clean the U-shaped tank and reservoir with medical disinfectant, and let them dry for later use; if it is an outpatient setting, simply remove the disposable collection pad and discard it without cleaning.

[0040] Compared with existing technologies (including prior art), this utility model has the following significant advantages: The base does not rely on a bed frame and can be placed on any plane, adapting to various scenarios such as outpatient clinics and wards; dual height and angle adjustment accommodates patients in different positions, including lying flat, side-lying, and semi-reclining, solving the scenario limitations of the prior art. An innovative liquid collection component actively collects medications and pus, preventing soiling of sheets / clothing; neither the prior art nor traditional devices have this function, reducing the workload of subsequent cleaning for medical staff. The core components are mechanical structures (telescopic rod, universal joint, collection slot), without complex components such as circuitry or Bluetooth, reducing manufacturing costs by more than 30%, lowering the failure rate, and facilitating clinical adoption; the prior art, due to its integrated lighting component, has higher structural complexity and cost. The ergonomic design of the neck groove and curved headrest, combined with silicone / sponge padding, evenly distributes pressure on the head and neck, preventing neck suspension and head compression; while the prior art has a soft support, it is not optimized for head pressure points during dressing changes, resulting in superior comfort.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
