一种气胸贴A pneumothorax patch

技术领域technical field

本实用新型属于医疗设备领域，涉及一种气胸贴。The utility model belongs to the field of medical equipment and relates to a pneumothorax patch.

背景技术Background technique

呼吸时随着胸壁扩张和膈肌收缩，胸腔内会产生负压，空气通过上呼吸道和支气管进入肺内；当胸壁回缩，膈肌松弛时，肺内产生正压将气体从呼吸道排出。开放性气胸是由于外伤导致胸壁组织全层受损造成的，当胸腔破裂并且伤口持续开放时，空气将从伤口进入胸腔并改变胸腔压力，空气无法进入肺内，最后导致气胸，肺萎缩，如果伤口超过气管直径，进入胸腔的空气将超过进入肺内的空气，从而导致机体缺氧。During breathing, with the expansion of the chest wall and the contraction of the diaphragm, negative pressure will be generated in the chest cavity, and air will enter the lungs through the upper airway and bronchi; when the chest wall retracts and the diaphragm relaxes, positive pressure is generated in the lungs to expel air from the airway. Open pneumothorax is caused by trauma to the full thickness of the chest wall tissue. When the chest cavity is ruptured and the wound continues to open, air will enter the chest cavity from the wound and change the pressure in the chest cavity. If the wound exceeds the diameter of the trachea, the air entering the chest cavity will exceed the air entering the lungs, resulting in hypoxia.

胸部开放伤的治疗方法是通过关闭伤口，避免空气进入胸腔。目前，一般采用无菌敷料或棉垫覆盖伤口，再用胶布或绷带包扎固定，使开放性气胸变为闭合性气胸并紧急送往医院进一步治疗。但是目前开放性气胸的紧急救治方法操作繁琐且效果不理想，传统敷料仅仅是单纯将创口封闭，胸腔内不断增加的积气、积血、积液不能排除从而存在隐患，这是导致伤员死亡的一个重要因素。Open chest wounds are treated by closing the wound to prevent air from entering the chest cavity. At present, sterile dressings or cotton pads are generally used to cover the wound, and then bandage or bandage is used to fix it, so that an open pneumothorax becomes a closed pneumothorax and is urgently sent to the hospital for further treatment. However, the current emergency treatment methods for open pneumothorax are cumbersome and unsatisfactory. Traditional dressings simply close the wound, and the increasing accumulation of gas, blood and fluid in the chest cavity cannot be eliminated, which leads to hidden dangers, which lead to the death of the wounded. an important factor.

具体实施方式Detailed ways

实施例：本申请提供了一种气胸贴，结合参考图1至图3，该气胸贴包括：基片1和单向阀2。Embodiment: The present application provides a pneumothorax patch, with reference to FIGS. 1 to 3 , the pneumothorax patch includes: a base sheet 1 and a one-way valve 2 .

单向阀2一体嵌于基片1上。The one-way valve 2 is integrally embedded on the substrate 1 .

单向阀2由内向外单向导通，对应胸腔伤口区域的位置，用于排出胸腔内的气体和/或液体。The one-way valve 2 conducts unidirectionally from the inside to the outside, corresponding to the position of the thoracic cavity wound area, and is used to discharge the gas and/or liquid in the thoracic cavity.

气胸贴的单向阀2对应伤口区域，基片1的内侧对应伤口周边区域。The one-way valve 2 of the pneumothorax patch corresponds to the wound area, and the inner side of the substrate 1 corresponds to the wound peripheral area.

基片1具备吸水能力，用于吸收单向阀导出的液体，基片1的内侧在单向阀2以外的区域设有自粘层5。The substrate 1 has the ability to absorb water, and is used for absorbing the liquid led out by the one-way valve. The inner side of the substrate 1 is provided with a self-adhesive layer 5 in the area other than the one-way valve 2 .

可选的，自粘层在未使用时有隔离层，在使用时将隔离层撕下露出粘性层进行粘贴固定。Optionally, the self-adhesive layer has an isolation layer when not in use, and when in use, the isolation layer is torn off to expose the adhesive layer for pasting and fixing.

可选的，基片1与单向阀2设有导液孔3，导液孔3与基片1成于一体；单向阀2设有排气孔4，排气孔4与外界相通。Optionally, the substrate 1 and the one-way valve 2 are provided with aliquid guide hole 3, and theliquid guide hole 3 is integrated with the substrate 1; the one-way valve 2 is provided with anexhaust hole 4, and theexhaust hole 4 communicates with the outside world.

导液孔3用于将通过单向阀2排出的积液积血导入吸水的基片1。Theliquid guide hole 3 is used to guide the fluid and blood accumulated through the one-way valve 2 into the water-absorbing substrate 1 .

在实际应用中，胸腔内的积液或积血通过单向阀2向外导出，由导液孔3导入基片1上，由于基片1是吸水材料，可以吸收导出的积液。对于胸腔内的积气，由单向阀2导出后直接由排气孔4排到外界环境中。In practical applications, the effusion or blood in the pleural cavity is led out through the one-way valve 2 and introduced into the substrate 1 through theliquid guide hole 3. Since the substrate 1 is a water-absorbing material, the derived effusion can be absorbed. The air accumulated in the thoracic cavity is directly discharged into the external environment through theexhaust hole 4 after being led out by the one-way valve 2 .

可选的，单向阀2是在胸腔正压大于预定值时开启并且胸腔正压小于或等于预定值时或胸腔负压状态下闭合的微压单向阀。Optionally, the one-way valve 2 is a micro-pressure one-way valve that opens when the positive thoracic pressure is greater than a predetermined value and is closed when the positive thoracic pressure is less than or equal to a predetermined value or in a state of negative thoracic pressure.

示例性的，在实际应用中，预定值可以选取3mmHg。Exemplarily, in practical applications, the predetermined value can be selected as 3 mmHg.

胸腔正常情况下是负压，在形成开放式气胸后，胸腔内由于积液和积气形成了正压，这种正压压力不会太大，通常略大于大气压，通过微压单向阀将积液积气排出，比如胸腔正压大于3mmHg时微压单向阀开启排出积气积液，使得胸腔恢复成正常的微负压，胸腔正压小于或等于3mmHg或胸腔为负压状态时微压单向阀闭合。Under normal circumstances, the thoracic cavity is negative pressure. After an open pneumothorax is formed, a positive pressure is formed in the thoracic cavity due to the accumulation of fluid and air. This positive pressure is not too large, usually slightly greater than the atmospheric pressure. Effusion of effusion and gas. For example, when the positive thoracic pressure is greater than 3mmHg, the micro-pressure one-way valve is opened to discharge the effusion and effusion, so that the thoracic cavity returns to a normal micro-negative pressure. Pressure check valve closed.

为了能排出胸腔内的积气和积液，同时起到封闭开放式气胸的作用，因此需要选用微压单向阀。需要说明的是，微压单向阀从内向外(即从胸腔内向外界环境)，需要满足胸腔正压大于预定值才会开启，当胸腔正压小于或等于预定值时均为闭合状态，当胸腔为负压时，外界气压大于胸腔压力，微压单向阀也是闭合的；微压单向阀从外向内(即从外界环境向胸腔内部)始终为常闭。In order to discharge the accumulated air and fluid in the pleural cavity, and at the same time play the role of sealing open pneumothorax, it is necessary to use a micro-pressure one-way valve. It should be noted that the micro-pressure one-way valve is opened from the inside to the outside (that is, from the inside of the thoracic cavity to the external environment), only when the positive thoracic pressure is greater than the predetermined value will be opened. When the thoracic cavity is under negative pressure, the external air pressure is greater than the thoracic cavity pressure, and the micro-pressure one-way valve is also closed; the micro-pressure one-way valve is always closed from the outside to the inside (that is, from the external environment to the inside of the thoracic cavity).

可选的，单向阀2的控制件材料包括硅胶、硅橡胶、异戊胶和聚四氟乙烯中的至少一种。Optionally, the material of the control member of the one-way valve 2 includes at least one of silica gel, silicone rubber, isoprene and polytetrafluoroethylene.

可选的，基片1的外侧和边缘为锁水结构。Optionally, the outer side and edge of the substrate 1 are water-locking structures.

通过将基片1的外侧和边缘制作成锁水结构，可以将基片1吸收的积血积液锁定在基片1内，保持气胸贴的外部清洁。By making the outside and edge of the base sheet 1 into a water-locking structure, the blood and effusion absorbed by the base sheet 1 can be locked in the base sheet 1, and the outside of the pneumothorax patch can be kept clean.

可选的，基片1的厚度为0.5-1cm。Optionally, the thickness of the substrate 1 is 0.5-1 cm.

可选的，基片1由高膨胀吸水材料组成，高膨胀吸水材料的吸水性能大于500％。Optionally, the substrate 1 is composed of a high-expansion water-absorbing material, and the water-absorbing performance of the high-expansion water-absorbing material is greater than 500%.

可选的，高膨胀吸水材料包括聚氨酯材料、吸水树脂、聚乙烯醇材料和藻酸盐材料中的至少一种。Optionally, the high expansion water absorbing material includes at least one of polyurethane material, water absorbing resin, polyvinyl alcohol material and alginate material.

开放性气胸胸腔内通常由积气、积液、积血，通过吸水材料能够有效吸收通过单向阀2排出的积血和积液，使用吸水性能高的高膨胀吸水材料能更好地吸收积血积液。The open pneumothorax usually contains air, fluid and blood in the pleural cavity. The water-absorbing material can effectively absorb the blood and fluid discharged through the one-way valve 2. The high-expansion water-absorbing material with high water absorption performance can better absorb the accumulation of blood. Hemorrhage.

需要说明的是，本申请中基片1的内侧指贴近胸腔的一侧，外侧指朝向外界环境的一侧。It should be noted that, in the present application, the inner side of the substrate 1 refers to the side close to the chest cavity, and the outer side refers to the side facing the external environment.

综上所述，本申请提供的气胸贴，通过基片和单向阀组成的气胸贴，将单向阀对准伤口位置，通过自粘层固定在胸腔上，操作简单，封闭性好，并且基片具备吸水能力，能够吸收由单向阀导出的积液，同时单向阀还能够排出积气，不仅能够将伤口封闭，防止外界气体、细菌进入胸腔，而且能够排出积液、积血、积气。To sum up, the pneumothorax patch provided by the present application uses a pneumothorax patch composed of a base sheet and a one-way valve, aligns the one-way valve with the wound position, and is fixed on the chest cavity through a self-adhesive layer, which is easy to operate, has good sealing, and The substrate has the ability to absorb water and can absorb the effusion derived from the one-way valve. At the same time, the one-way valve can also discharge the accumulated gas. gas.
