一种防压力性损伤呼吸机面罩An anti-pressure injury ventilator mask

技术领域technical field

本发明属于医用器械领域，具体是一种防压力性损伤呼吸机面罩。The invention belongs to the field of medical devices, in particular to a pressure injury-proof ventilator mask.

背景技术Background technique

呼吸机面罩作为呼吸机与患者之间的界面与患者直接接触，是用来辅助呼吸机进行通气的一个工具,在治疗过程中有着举足轻重的作用。一般患者使用呼吸机的时间最少要维持6-8h以上，面罩长时间的压迫增加了垂直压力，使颜面部面罩压迫处血流被阻断而容易发生压力性损伤，且压迫时间越长，压力性损伤导致溃疡的发生率越高。无创正压通气患者回顾性调查发现，在使用无创正压通气过程中，颜面部压力性损伤发生率为25.49％。As the interface between the ventilator and the patient, the ventilator mask is in direct contact with the patient. It is a tool used to assist the ventilator in ventilation, and plays a pivotal role in the treatment process. Generally, the patient needs to use the ventilator for at least 6-8 hours. The long-term compression of the mask increases the vertical pressure, which blocks the blood flow at the compressed part of the face mask and is prone to pressure injury. The longer the compression time, the higher the pressure. Sexual injuries lead to a higher incidence of ulcers. A retrospective survey of patients with noninvasive positive pressure ventilation found that the incidence of facial pressure injury was 25.49% during the use of noninvasive positive pressure ventilation.

目前，为了减少压力性损伤，常用的解决办法对连续使用无创呼吸机的患者每隔4小时放松1次，或者采用敷料预防无创正压通气患者鼻面部压力性损伤。但上呼吸机的患者因病情比较重，需要较长时间使用无创呼吸机，有些甚至需要每天24小时持续使用多日，有的COPD患者甚至出院后在家还要经常佩戴面罩使用家用呼吸机。目前临床采用的各种防压敷料贴到脸上，敷料与皮肤接触的一面一般都粘有一层薄薄的可溶性透明胶以固定面贴不移动，粘贴时间太久对面部有一定的刺激，增加不适，敷料而且需要经常更换，增加患者费用，敷料还是避免不了产生压力性损伤，压力性损伤指局部的皮肤或皮下软组织损伤，通常发生在骨隆突处或医疗器械相关的位置。是皮肤完整的或开放性溃疡的损伤，并可能伴有疼痛。医疗器械相关性压力性损伤，损伤部位性状通常与医疗器械性状一致。由于面罩产生的医疗器械相关性压力性损伤，导致患者皮肤出现伤口甚至感染，无法再继续持续佩戴呼吸机面罩，增加患者痛苦及医疗花费(本技术方案中的伤口指代但不局限于压力性损伤所造成的伤口)。At present, in order to reduce pressure injury, the common solution is to relax patients who are continuously using non-invasive ventilator every 4 hours, or use dressings to prevent nasal and facial pressure injury in patients with non-invasive positive pressure ventilation. However, patients on ventilators need to use non-invasive ventilators for a long time due to their severe illness, and some even need to use them 24 hours a day for several days. Some COPD patients even often wear a mask at home to use a home ventilator after being discharged from the hospital. At present, various anti-pressure dressings used clinically are attached to the face. The side of the dressing that is in contact with the skin is generally pasted with a thin layer of soluble transparent glue to fix the surface patch and not move. Discomfort, dressings need to be changed frequently, increasing patient costs, and dressings still cannot avoid pressure injuries, which refer to localized skin or subcutaneous soft tissue injuries, usually occurring at bony prominences or medical device-related locations. An injury that is an intact or open ulcer of the skin and may be painful. In medical device-related pressure injuries, the characteristics of the injury site are usually consistent with those of the medical device. Due to the medical device-related pressure injury caused by the mask, the patient's skin has wounds or even infection, and it is no longer possible to continue to wear the ventilator mask, which increases the patient's pain and medical expenses (the wound in this technical solution refers to but is not limited to pressure. wounds caused by injuries).

当代医学亟需一款好的面罩应充分结合人体面部工程学特点确保配戴舒适、密封良好、从而提高疗效并确保无创呼吸机各项功能的准确运行，尤其应在设计一款预防压力性损伤或保护已经发生压力性损伤患者的伤口时，提供一种包裹患者伤口，避免伤口受到挤压而加深溃疡及感染的呼吸机面罩。Contemporary medicine urgently needs a good face mask, which should fully combine ergonomic features to ensure comfortable wearing and good sealing, thereby improving efficacy and ensuring the accurate operation of various functions of non-invasive ventilators, especially when designing a mask to prevent pressure injuries. Or when protecting the wound of a patient who has suffered pressure injury, a ventilator mask that wraps the patient's wound and prevents the wound from being squeezed to deepen ulcers and infection.

Thenotch 15 is adapted to be connected with the notch of the airway 3 .

具体实施过程如下：在使用过程中，医护人员将呼吸机面罩覆盖于患者面部，此时呼吸机面罩的颔部与患者的面部贴合，此时颔部的过渡弧9与患者脸部轮廓扣合，以保持呼吸机面罩的固定，随后颔部外凸的此时患者颔部的皮肤或伤口被外凸的部分包裹，避免皮肤或伤口被面罩本身压迫，皮肤在未被压迫的时候保持自然的完整情况，减少了皮肤受压迫后损伤的可能性，降低了患者面部感染的可能性。The specific implementation process is as follows: during use, the medical staff covers the face of the patient with the ventilator mask, and the chin part of the ventilator mask is fitted with the patient's face at this time, and thetransition arc 9 of the chin part is buckled with the contour of the patient's face. to keep the ventilator mask fixed, and then the skin or wound of the patient's chin is wrapped by the protruding part to prevent the skin or wound from being compressed by the mask itself, and the skin remains natural when it is not compressed. The complete condition of the skin reduces the possibility of injury after skin compression and reduces the possibility of infection of the patient's face.

当呼吸机面罩扣合后，在患者鼻翼两侧和鼻梁部位，由于设置了莫比乌斯结构，所以患者鼻翼两侧的皮肤或伤口与莫比乌斯环4结构贴合时始终处于莫比乌斯环4的表面位置，此时皮肤或伤口将莫比乌斯环4向内压，皮肤或伤口与弧形凹槽间隙配合，减少了皮肤或伤口受到的压迫感。When the ventilator mask is fastened, on both sides of the patient's nose and the bridge of the nose, due to the Mobius structure, the skin or wounds on both sides of the patient's nose are always in theMobius ring 4 structure when they are fitted. The surface position of theUsus ring 4. At this time, the skin or the wound presses theMobius ring 4 inward, and the skin or the wound fits with the arc-shaped groove to reduce the pressure on the skin or the wound.

接入输氧机2时，医护人员先将导气管3依次穿过导向口11和进气通道10，避免导气管3插入时失准，从而损伤患者的会厌部，同时在完成连接后操作人员将铰杆13向上扳动，此时将铰杆13的凹口15与凸起14对准扣合，在扣合过程中凸起14的的头部由开合过程转化为收束过程，扣合完成后凸起14的头部重新开合，此时对凹口15进行限制卡合，避免患者拔管。When connecting to the oxygen delivery machine 2, the medical staff first pass the airway tube 3 through theguide port 11 and theair intake channel 10 in order to avoid misalignment when the airway tube 3 is inserted, thereby damaging the epiglottis of the patient. Thehinge rod 13 is pulled upward, and at this time, thenotch 15 of thehinge rod 13 is aligned and buckled with theprotrusion 14. During the buckling process, the head of theprotrusion 14 is converted from the opening and closing process to the closing process, and the buckling process is completed. After completion, the head of theprotrusion 14 is re-opened and closed, and at this time, thenotch 15 is restricted and engaged to prevent the patient from extubation.

在需要吸痰时，医护人员将推板7移开，推板7后行时，依次带动连杆6和转动销5后移，此时推板7遮盖的缺口显露，此时医护人员通入吸痰器对患者喉部进行吸痰操作，此时将吸痰操作在不需拔管的情况进行，防止患者喉部痰液撒落对医护环境进行污染，同时简化了操作流程，患者，提升了操作效率。When phlegm needs to be sucked, the medical staff removes thepush plate 7, and when thepush plate 7 moves backward, it drives the connecting rod 6 and therotating pin 5 to move backward in turn. At this time, the gap covered by thepush plate 7 is exposed, and the medical staff enters the The sputum suction device performs sputum suction operation on the patient's throat. At this time, the sputum suction operation is performed without extubation, which prevents the sputum from the patient's throat from spilling and pollutes the medical and nursing environment, and simplifies the operation process. operational efficiency.

当吸痰完成后推板7受到扭簧8的作用力而自动回位，此时颔部的凹口15沿导气管3的缺口处滑入，避免了推板7产生震动从而错位的现象，保持了密封性。When the suction is completed, thepush plate 7 is automatically returned to the position by the force of thetorsion spring 8. At this time, thenotch 15 of the jaw portion slides in along the gap of the airway 3, so as to avoid the phenomenon that thepush plate 7 is vibrated and dislocated. Sealing is maintained.
