Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to a prone ventilation pillow. Background Technology

[0002] Prone ventilation, as an adjunctive treatment, can increase the patient's functional residual capacity, improve the diaphragm's movement pattern and position, facilitate the drainage of secretions, improve ventilation and blood perfusion, reduce the pressure of the mediastinum and heart on the lungs, improve chest wall compliance, promote the expansion of the lungs in atelectasis areas, and thus regulate the ventilation-perfusion ratio of the lungs.

[0003] In existing technologies, hospitals generally use pillows to support patients in order to relieve the pressure on their bodies, maintain smooth breathing, and maintain blood circulation throughout the body. In this way, the patient's head needs to be turned to one side. Therefore, if the patient maintains this position for a long time, it will cause cervical discomfort. In addition, the support of the pillow is not strong enough, and the patient's chest and abdomen will still be compressed when the patient is in a prone position for a long time.

[0004] To address the aforementioned issues, for example, Chinese utility model patent CN220213285U discloses a prone-position ventilation pillow. The size of the C-shaped pillow can be adjusted by moving the left and / or right pillow body, making it suitable for the face and head of different individuals and providing good facial support. This prone-position ventilation pillow allows the patient to lie face down, relieving neck pain. However, this patent only effectively supports the head and lacks a structure to support other parts of the patient's body, thus failing to alleviate discomfort. Another example is Chinese utility model patent CN210812148U, which discloses a prone-position ventilation pillow that adjusts the height and comfort of the patient during prone ventilation by controlling the gas volume of each inflation part, maximizing the effectiveness of prone ventilation. The multiple inflatable sections of a prone ventilation pillow can effectively support the patient's head, chest, and abdomen. However, the multiple inflatable sections cannot be effectively fixed, causing the inflatable sections to move during the patient's prone position. Furthermore, the shape of the inflatable sections may change due to changes in the direction of force, which may exacerbate the movement of the inflatable sections. For critically ill patients, this means that the inflatable sections may move out of their initial position and actually cause pressure on the patient. Utility Model Content

[0005] The purpose of this invention is to provide a prone ventilation pillow, which consists of multiple pillow bodies with adjustable spacing between them. It can be adjusted and fixed according to the patient's body size to effectively support the patient's key parts, thereby solving the technical problems in the prior art.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1 As shown, this utility model provides a specific embodiment of a prone ventilation pillow, including a head pillow 2, a jaw pillow 3, a chest pillow 4, an abdomen pillow 5, and a leg pillow 6, which are set on a support 1.

[0031] The support 1 is used to place the entire prone ventilation pillow on the hospital bed. The support 1 makes the head pillow 2, jaw pillow 3, chest pillow 4, abdomen pillow 5 and leg pillow 6 form a whole.

[0032] Head pillow 2 is used to support the patient's head, jaw pillow 3 is used to support the patient's jaw, chest pillow 4 is used to support the patient's chest, abdomen pillow 5 is used to support the patient's hips, and leg pillow 6 is used to support the patient's knees and lower legs; thus ensuring that the patient's head, chest, hips and lower legs and other major body parts are properly supported and avoid direct contact with the bed surface.

[0033] And ensure that the patient's abdomen is suspended to reduce pressure on the inferior vena cava, which helps maintain venous return.

[0034] Furthermore, soft padding or other elastic supports should be selected for the head pillow 2, jaw pillow 3, chest pillow 4, abdomen pillow 5, and leg pillow 6 to ensure that these areas are not compressed and that the patient's head, chest, hips, and lower legs, and other major body parts, are not excessively compressed.

[0035] Furthermore, the head pillow 2, jaw pillow 3, chest pillow 4, abdomen pillow 5, and leg pillow 6 are arranged parallel to each other, and can move relative to the support 1. The distance between the head pillow 2, jaw pillow 3, chest pillow 4, abdomen pillow 5, and leg pillow 6 can be adjusted according to the patient's body shape to effectively support the key parts of the patient's body and prevent the head pillow 2, jaw pillow 3, chest pillow 4, abdomen pillow 5, or leg pillow 6 from moving relative to each other when the patient is lying prone, thus avoiding pressure on the patient and helping to maintain normal respiratory rate and venous return.

[0036] This embodiment also provides an example in which the head pillow 2, jaw pillow 3, chest pillow 4, abdomen pillow 5, and leg pillow 6 can move relative to the support 1, as shown in the figure:

[0037] The bracket 1 is provided with two parallel slide rails 11. The headrest 2, jaw rest 3, chest rest 4, abdomen rest 5 and leg rest 6 are each provided with an independent base 12. Two sliders 13 are symmetrically provided on both sides of the bottom of the base 12. The bottom of the slider 13 has a vertically provided groove 15 along the moving direction of the slider 13, so that the slide rail 11 can be locked in the groove 15. The two sliders 13 are slidably connected relative to the two slide rails 11. By moving the base 12 corresponding to the headrest 2, jaw rest 3, chest rest 4 and abdomen rest 5, the distance between the headrest 2, jaw rest 3, chest rest 4, abdomen rest 5 and leg rest 6 can be adjusted.

[0038] Furthermore, the slide rail 11 has a horizontal through groove 14 corresponding to the movement range of each base 12 in the horizontal direction. The two ends of the slide seat are respectively provided with a limiting rod 16 inside the slide groove 15. The limiting rod 16 passes through the through groove 14 to limit the movement range of the base 12, so that medical staff and patients can clearly know the corresponding support parts of the head pillow 2, jaw pillow 3, chest pillow 4, abdomen pillow 5 and leg pillow 6.

[0039] To improve the movement accuracy of the headrest 2, jaw rest 3, chest rest 4, abdomen rest 5, and leg rest 6, and to control the spacing between them, this embodiment provides the following examples:

[0040] As shown in the figure: the slider 13 is provided with at least two gears 17 inside the slide groove 15. The gears 17 can be rotated. The rotation axis of the gears 17 is set perpendicular to the moving direction of the slider 13. The top of the slide rail 11 is provided with a rack 18. The gears 17 mesh with the rack 18. Through the meshing of the gears 17 and the rack 18, the movement between the slider 13 and the slide rail 11 can be better controlled.

[0041] A cylindrical slider 141 is provided in the through groove 14. Baffles 142 are provided on both sides of the cylindrical slider 141. A threaded hole 143 is provided along the axis of the cylindrical slider 141, penetrating the cylindrical slider 141 and the baffles 142. A through hole is provided in the cylindrical slider 141 at the same height as the threaded hole 143. A bolt 144 passes through the through hole and can be threadedly connected to the threaded hole 143 of the cylindrical slider 141.

[0042] By tightening the bolt 144, the baffle 142 can be attached to and locked with the slide rail 11, so that the baffle 142 and the slide rail 11 are relatively fixed, thereby limiting the relative movement between the slide and the slide rail 11, and thus fixing the position of the adjusted headrest 2, jaw rest 3, chest rest 4, abdomen rest 5 and leg rest 6.

[0043] A handle 145 is provided at the head of bolt 144 to facilitate the rotation of bolt 144.

[0044] Furthermore, to improve patient comfort when using the head pillow 2, jaw pillow 3, chest pillow 4, abdomen pillow 5, and leg pillow 6, the following embodiments are provided:

[0045] The head pillow 2 has a first groove 21 on the side facing the occipital bone, which is used to support the patient's forehead. The jaw pillow 3 has a second groove 31 on the side facing the head pillow 2, which is used to support the patient's lower jaw. The head pillow 2 and the jaw pillow 3 are combined to support the patient's head. The presence of the first groove 21 and the second groove 31 makes the head fit the patient's head better, and the patient's head and lower jaw fit the head pillow 2 and jaw pillow 3 better.

[0046] The patient's head can be positioned normally downwards, and the space between the headrest 2 and the jaw rest 3 can be used to place medical devices related to assisted breathing.

[0047] Two first U-shaped grooves 41 are symmetrically arranged on the side of the chest pillow 4 facing the abdomen pillow 5 to avoid pressure on the breasts of female patients; a second U-shaped groove 51 is arranged in the middle position of the abdomen pillow 5 facing the leg pillow 6 to avoid pressure on the genitals of male patients.

[0048] Furthermore, the contact surface between the leg pillow 6 and the patient's lower leg forms a 15° angle with the horizontal plane, allowing the patient to raise their lower leg while in a prone position for an extended period, thus preventing numbness caused by prolonged lower leg movement.

[0049] Furthermore, the leg pillow 6 has two upward-opening third U-shaped grooves 61 symmetrically arranged in the vertical direction with its central axis of movement as the axis of symmetry. The lowest position of the third U-shaped groove 61 is on the same plane as the support surface on the leg pillow 6 used to support the knee joint, so that the patient's lower leg can be placed flat in the third U-shaped groove 61 to promote blood circulation in the patient's lower limbs.

[0050] Patients can choose to place their lower legs flat in the third U-shaped groove 61 or raise their lower legs on the support surface of the leg pillow 6, which is inclined at 15° to the horizontal plane, according to their own needs. They can also alternate between the two positions while prone. The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
