Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary devices, in particular to a prone position ventilation auxiliary pad. Background Art

[0002] Prone ventilation is widely used in the ICU as a lung protection strategy. Its main principle is to effectively improve the ventilation-blood flow ratio, re-expand the collapsed alveoli on the dorsal side, allow the secretions in the lungs and trachea to be well drained under the action of gravity, and reduce the pressure of the heart and mediastinum on the sagging lung area.

[0003] Prone ventilation as an auxiliary treatment method refers to the use of a turning bed, turning machine or manual operation to allow the patient to undergo mechanical ventilation in the prone position, so as to promote the expansion of the lungs in the drooping and atelectasis area, thereby achieving the adjustment of the ventilation-perfusion ratio and the improvement of the oxygenation of patients with respiratory failure, and ultimately ensuring the recovery of lung function as soon as possible and early weaning from the use of ventilators. The principle of prone ventilation is to improve alveolar ventilation function, increase the ventilation-perfusion ratio, improve oxygenation and prevent ventilator-associated lung injury.

[0004] The existing technology cannot be used by patients with tracheotomy or endotracheal intubation at the same time, and it is not easy to operate during sputum suction, which has a great impact on treatment and nursing. In addition, due to the fat or thin body shape of the patient, some prone ventilation devices are not suitable.

[0005] The utility model patent with application number 2020220561279 discloses an adjustable prone ventilation auxiliary pad, including a left head pad, a right head pad, a left shoulder and chest pad, a right shoulder and chest pad, a telescopic rod, and a mattress clamping plate arranged at the bottom of the left shoulder and chest pads and the right shoulder and chest pads; the left head pad, the right head pad, the left shoulder and chest pad, and the right shoulder and chest pad are sequentially connected to form a closed loop through the telescopic rod, and an artificial airway reserved hole is formed in the middle of the closed loop, and the left shoulder and chest pad and the right shoulder and chest pad each include an integrally arranged vertical portion and a horizontal portion, and the top of the horizontal portion is provided with a slope surface inclined from one end close to the left head pad to one end away from the left head pad. The utility model can reduce the pressure on the patient's facial skin in the prone position, and can perform sputum suction and other operations through the reserved artificial airway reserved hole to improve the patient's comfort.

[0006] When the patient is given prone ventilation treatment, the skin is easily damaged by compression due to the long time (preferably more than 12 hours a day); pressure sores are prone to occur, and the patient's head, neck, chest, abdomen and knees are also easily damaged; these parts of the patient often need to be padded for support and protection. And when the patient is in the prone position, because the upper body leans forward, the body needs to be supported by the hands and elbows. After long-term support, the patient is prone to physical fatigue. At the same time, critically ill patients have accumulated sputum and it is difficult for them to effectively expectorate independently. However, the above patents have not been able to solve this problem well. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Under the premise of not departing from the design concept of the utility model, various modifications and improvements made by ordinary people in this field to the technical solutions of the utility model should fall within the protection scope of the utility model. Example

[0029] like Figure 1 and Figure 2 As shown, a prone position ventilation auxiliary pad includes a left support pad 1 and a right support pad 2 arranged at the front for supporting the head and chest, and the left support pad 1 and the right support pad 2 are symmetrically arranged and the spacing between the left / right support pads is adjustable. The left support pad 1 and the right support pad 2 are connected by a connector, and the length of the connector is adjustable to adjust the spacing between the left support pad 1 and the right support pad 2. In this embodiment, the connector adopts an adjustment belt 10 respectively fixed to the left support pad 1 and the right support pad 2, and Velcro is fixed on the adjustment belt 10. The Velcro adjustment belt is used to adjust the spacing between the left support pad 1 and the right support pad 2 after fixing. The left support pad 1 and the right support pad 2 adopt a split air cushion design, which is convenient for operation in medical activities and can be adapted to different diagnosis and treatment beds.

[0030] The left support pad 1 and the right support pad 2 both include an elbow pad 3 arranged at the bottom, a support portion 4 in the middle, and an air cushion layer 5 arranged at the top. The support portion 4 is made of a material that can provide support, such as sponge, silicone, latex, or foam; the elbow pad 3 is a component that extends outward from the support portion 4, and the top surface of the elbow pad 3 can be made of a relatively soft material, such as air cushion, silicone, latex, sponge, or cotton cloth.

[0031] The air cushion layer 5 is provided with an upwardly protruding shoulder support portion 8 at a position between the head cushion 6 and the chest cushion 7. The head cushion 6 is hollow in design, and an inner protrusion 61 extending relatively inward is provided at the position for supporting the forehead. After the left support pad 1 and the right support pad 2 are assembled together, the hollow portion of the head cushion 6 can form an elliptical hollow portion that matches the face shape; the edge of the air cushion layer 5 on the top surface of the hollow portion is provided with a face contour groove 62 that is concave inward and high outward and matches the face contour. A chest contour groove 71 that is concave inward and high outward and matches the chest contour is provided at the inner edge of the air cushion layer on the top surface of the chest cushion 7; four vibration components 72 are symmetrically inlaid inside the chest contour groove. In this embodiment, the vibration component 72 adopts a conventional adjustable vibration element, which is fixed on the inner side of the air cushion layer; this embodiment does not make effective improvements to the vibration element, the control mode of the vibration element, and the fixing method of the vibration element, but only uses products similar to the vibration element in the massage device on the market, which will not be elaborated here.

[0032] The shoulder support portion 8 is an inverted L-shaped support portion with a wide and thick bottom, or a shark fin-shaped support portion with a wide and thick bottom and a narrow and thin upper portion.

[0033] A hip-leg auxiliary pad 9 for supporting the hip to the knee is arranged at the rear of the left support pad 1 and the right support pad 2; the hip-leg auxiliary pad 9 adopts an air cushion. The air cushion can be inflated to adjust the height of the air cushion and the fit of the human body. The height adjustment function enables the cooperation of the hip-leg auxiliary pad 9 with the left support pad 1 and the right support pad 2 to adjust the tilt angle of the human body.

[0034] Most of the body fluids and secretions are non-Newtonian fluids. Although the traditional slapping expectoration method is conducive to the thinning of sputum, the sputum in the upright position is more likely to settle downward to the end. In the prone position, at a reasonable angle, the vibration of the vibrating plate at the chest position can make the shear-thinned liquid more conform to the desired expectoration direction.

[0035] The hip and leg auxiliary pad 9 adopts the setting of air cushion, which can evenly disperse the pressure and increase the patient's prone position tolerance time. At the same time, it can also adjust the patient's tilt angle to find a balance between facilitating sputum discharge and craniomaxillofacial blood perfusion pressure.

[0036] The hip and leg auxiliary pad 9 can be connected to the left support pad 1 and the right support pad 2 through a Velcro adjustment belt 10. The components are connected using a Velcro adjustment belt 10 to facilitate adjustment of width and length and increase the adaptability of the patient.

[0037] The air cushion layer 5 or the air cushion is made of PVP material, and an air nozzle is arranged on the air cushion layer 5 or the air cushion. Air cushions made of PVP material are widely used in outdoor sports and family health care. The safety and reliability of the material are guaranteed. At the same time, the air cushion itself can reduce the occurrence of bedsores in long-term bedridden patients and reduce pressure injuries.

[0038] The above implementation is only for illustrating the technical concept and features of the utility model, and its purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and it cannot be used to limit the protection scope of the utility model. Any equivalent transformation or modification made according to the spirit of the utility model should be included in the utility model.
