Description

一种安全隔离式人工呼吸器A safety isolation artificial respirator

技术领域technical field

本发明涉及可植入式精密的电子设备技术领域,具体是一种安全隔离式人工呼吸器。主要用于协助医务人员抢救患者时实施人工呼吸,同时有效隔离患者与医务人员之间的气体、分泌物、体液,在不影响人工呼吸实施的情况下保障了人工呼吸实施者的健康及安全。该医疗设备还可用于协助经专业培训人员在非医疗区域内对突发呼吸心跳骤停人员。The invention relates to the technical field of implantable precise electronic equipment, in particular to a safety isolation artificial respirator. It is mainly used to assist medical personnel to implement artificial respiration when rescuing patients, and at the same time effectively isolate the gas, secretions, and body fluids between patients and medical personnel, ensuring the health and safety of artificial respiration implementers without affecting the implementation of artificial respiration. The medical device can also be used to assist specially trained personnel in non-medical areas for sudden respiratory and cardiac arrest personnel.

背景技术Background technique

昏迷患者或心跳停止患者在排除气道异物,采用徒手方法使呼吸道畅通后,如未恢复自主呼吸,应立即予以人工呼吸,以保证不间断地向患者供氧,防止重要器官因缺氧造成不可逆性损伤。正常空气中氧浓度约为21%,经呼吸吸入肺后人体大约可利用3%~5%,于是人体呼出气体中的氧浓度含量可达16%~18%,只要在进行人工呼吸时给患者的通气量稍大于正常,可使人工呼吸过程中氧含量的绝对值不少于自主呼吸时的氧含量,进而有效保证身体重要器官的氧供应,避免由于缺氧而导致重要脏器的损害。If the patient in a coma or a patient with cardiac arrest does not resume spontaneous breathing after removing foreign bodies in the airway and unblocking the airway with bare hands, artificial respiration should be given immediately to ensure uninterrupted supply of oxygen to the patient and prevent irreversible damage to vital organs due to hypoxia. sexual injury. The oxygen concentration in normal air is about 21%, and the human body can use about 3% to 5% after breathing into the lungs, so the oxygen concentration in the exhaled air of the human body can reach 16% to 18%, as long as the patient is given artificial respiration. The ventilation volume is slightly larger than normal, so that the absolute value of oxygen content during artificial respiration is not less than the oxygen content during spontaneous breathing, thereby effectively ensuring the oxygen supply of important organs of the body and avoiding damage to important organs due to hypoxia.

目前常用的人工呼吸方法有两种,即口对口呼吸和口对鼻呼吸。There are two commonly used artificial respiration methods, namely mouth-to-mouth breathing and mouth-to-nose breathing.

1.口对口呼吸1. Mouth-to-mouth breathing

根据患者的病情选择打开气道的方法,患者取仰卧位,抢救者一手放在患者前额,并用拇指和食指捏住患者的鼻孔,另一手握住颏部使头尽量后仰,保持气道开放状态,然后深吸一口气,张开口以封闭患者的嘴周围(婴幼儿可连同鼻一块包住),向患者口内连续吹气2次,每次吹气时间为1~1.5秒,吹气量1000毫升左右,直到胸廓抬起,停止吹气,松开贴紧患者的嘴,并放松捏住鼻孔的手,将脸转向一旁,用耳听有否气流呼出,再深吸一口新鲜空气为第二次吹气做准备,当患者呼气完毕,即开始下一次同样的吹气。如患者仍未恢复自主呼吸,则要进行持续吹气,成人吹气频率为12次/分钟,儿童15次/分钟,婴儿20次/分钟,但是要注意,吹气时吹气容量相对于吹气频率更为重要,开始的两次吹气,每次要持续1~2秒钟,让气体完全排出后再重新吹气,一分钟内检查颈动脉搏动及瞳孔、皮肤颜色,直至患者恢复复苏成功,或死亡,或准备好做气管插管。The method of opening the airway is selected according to the patient's condition. The patient is placed in a supine position. The rescuer puts one hand on the patient's forehead, pinch the patient's nostril with the thumb and index finger, and holds the chin with the other hand to tilt the head back as much as possible to keep the airway open. state, then take a deep breath, open the mouth to close the patient's mouth (infants and young children can be covered with the nose), and blow continuously into the patient's mouth for 2 times, each blowing time is 1-1.5 seconds, and the blowing volume is 1000 About milliliters until the chest rises, stop blowing, release the patient's mouth, and relax the hand holding the nostril, turn the face to the side, listen to the air to exhale with the ear, and take a deep breath of fresh air for the second Prepare for the next blow, and when the patient has finished exhaling, start the next blow. If the patient has not resumed spontaneous breathing, continuous insufflation should be performed. The insufflation frequency is 12 times/min for adults, 15 times/min for children, and 20 times/min for infants. The frequency of air is more important. The first two blows last for 1 to 2 seconds each time. Let the air be completely exhausted and then blow again. Check the carotid pulse, pupil, and skin color within one minute until the patient resumes recovery. Success, or death, or ready for intubation.

2.口对鼻呼吸2. Mouth-to-nose breathing

当患者有口腔外伤或其他原因致口腔不能打开时,可采用口对鼻吹气,其操作方法是:首先开放患者气道,头后仰,用手托住患者下颌使其口闭住。深吸一口气,用口包住患者鼻部,用力向患者鼻孔内吹气,直到胸部抬起,吹气后将患者口部张开,让气体呼出。如吹气有效,则可见到患者的胸部随吹气而起伏,并能感觉到气流呼出。When the patient has oral trauma or other reasons and the oral cavity cannot be opened, mouth-to-nose blowing can be used. Take a deep breath, wrap your mouth around the patient's nose, and blow forcefully into the patient's nostrils until the chest lifts up. After blowing, open the patient's mouth to allow the air to exhale. If the blow is effective, you can see the patient's chest rise and fall with the blow and feel the air exhaling.

因此不论是口对口人工呼吸还是口对鼻人工呼吸,施救操作者不可避免的与患者进行紧密接触,于是患者的气体、分泌物、体液等不可避免的被施救者所接触。由于心肺复苏大多发生在紧急情况下,于是施救的医务人员不可避免的暴露于危险之中。如果患者患有呼吸道传播疾病,例如肺结核传播期、人禽流感、非典、埃博拉等,施救者很可能会因为气体接触而发生感染;如果患者患有消化道传播疾病,口腔内残留呕吐物或者人工呼吸过程中呕吐发作,施救者接触到呕吐物后很可能会被交叉感染;如果患者患有口周疱疹,施救者在人工呼吸过程中与患者紧密接触,则给疱疹病毒感染的可能性非常大;此外梅毒是由一种由苍白螺旋体感染导致的一种性病,它可以通过口腔黏膜传播进入人体,若在人工呼吸过程中不采取相应措施,则可能被交叉感染。Therefore, whether it is mouth-to-mouth artificial respiration or mouth-to-nose artificial respiration, the rescue operator is inevitably in close contact with the patient, so the patient's gas, secretions, body fluids, etc. are inevitably contacted by the rescuer. Because cardiopulmonary resuscitation mostly occurs in emergency situations, the rescue medical staff are inevitably exposed to danger. If the patient suffers from respiratory diseases, such as tuberculosis transmission, human avian influenza, SARS, Ebola, etc., the rescuer is likely to be infected due to gas contact; if the patient suffers from digestive tract diseases, residual vomiting in the mouth If the patient suffers from perioral herpes and the rescuer is in close contact with the patient during artificial respiration, the rescuer will be infected with herpes virus. In addition, syphilis is a sexually transmitted disease caused by Treponema pallidum infection, which can be transmitted into the human body through the oral mucosa. If no corresponding measures are taken during artificial respiration, it may be cross-infected.

然而昏迷患者及心跳停止患者的抢救分秒必争,不允许施救者在抢救前确认被施救者是否患有传染病。于是绝大多数施救者在实施人工呼吸时出于职业习惯及本能反应,无丝毫犹豫得采取直接接触的口对口或口对鼻人工呼吸,忽略了自身的健康及安全。因此,为了保护心肺复苏过程中施救人员的健康及安全,一种有效的施救者与患者之间气体、分泌物、体液隔离措施必须被建立。However, every second counts for the rescue of comatose patients and patients with cardiac arrest, and the rescuer is not allowed to confirm whether the rescued person has an infectious disease before the rescue. Therefore, most rescuers do not hesitate to use mouth-to-mouth or mouth-to-nose artificial respiration with direct contact due to professional habits and instinctive reactions when implementing artificial respiration, ignoring their own health and safety. Therefore, in order to protect the health and safety of rescuers during CPR, an effective gas, secretion, and body fluid isolation measure between the rescuer and the patient must be established.

目前,常用的隔离措施是人工呼吸膜。人工呼吸膜的构造简单,主体有PVC膜做成一次性CPR屏障消毒面膜,中间的呼吸口由环氧乙烷消毒过的无纺布制作而成。虽然人工呼吸膜可以有效阻挡部分固体物,但对患者气体、分泌物、体液仍穿透过无纺布至施救者一侧,导致安全隔离失败。针对目前急救时人工呼吸施救者所面临的风险以及当前使用方法、器材的缺陷,我们发明了安全隔离式人工呼吸器,以解决以上问题。At present, the commonly used isolation measure is artificial respiration membrane. The structure of artificial respiration membrane is simple, the main body is made of PVC membrane to make a disposable CPR barrier disinfection mask, and the breathing port in the middle is made of non-woven fabric sterilized by ethylene oxide. Although the artificial respiration membrane can effectively block some solid objects, the patient's gas, secretions, and body fluids still penetrate through the non-woven fabric to the rescuer's side, resulting in the failure of safety isolation. In view of the risks faced by rescuers of artificial respiration during emergency and the defects of current use methods and equipment, we have invented a safety isolation artificial respirator to solve the above problems.
