Description

一次性外用止血止液装置 Topical hemostatic disposable liquid stopper means

技术领域 FIELD

[0001] 本发明属于医疗器械领域,涉及一种一次性外用止血止液装置。 [0001] The present invention belongs to the field of medical devices, topical hemostatic relates to a disposable liquid stopper means.

背景技术 Background technique

[0002] 在临床护理工作中,常常会遇到患者因病情变化或术后并发症等各种原因出现伤口持续渗血渗液的现象,如引流管拔除后伤口渗液,中心静脉导管拔管后渗液等。 [0002] In clinical care, often encounter the phenomenon of wound exudate continued bleeding patients for various reasons, changes in condition or postoperative complications, such as drainage tube after removal of wound exudate, central venous catheter extubation after exudate and so on. 伤口持续渗液不仅增加患者的不适感,减弱患者的治疗信心,还增加医务人员的工作量,甚至引发医疗纠纷,目前临床上常用的止血、止液方法五花八门,但具体行之有效又物美价廉却未曾出现过。 Wound exudate not only continued to increase patient discomfort, weakened confidence in the treatment of patients, but also increased the workload of medical staff, and even lead to medical disputes, currently used to stop bleeding, stop solution method clinically varied, but the specific effective and reasonable price Lim has not appeared. 具体说明目前临床上常用的止血、止液方法: DETAILED DESCRIPTION currently used clinically hemostasis, stop solution method:

[0003] 1、更换敷料:是目前临床上最传统也是使用最广泛的方法之一。 [0003] 1, change dressings: is clinically most traditional and one of the most widely used method. 传统敷料包括纱布、棉垫、绷带等基本材料,。 Traditional dressings including gauze, pad, bandages and other basic materials. 主要通过频繁的更换伤口敷料,保持伤口干燥,直到伤口愈合为止。 Up mainly by frequent replacement of the wound dressing, the wound remains dry until the wound healed. 由于伤口渗血、渗液时间不固定,经常在患者更换体位时明显,而临床医生又因工作量大,事情多,不能做到及时换药。 As the wound bleeding, exudate time is not fixed, often evident when the patient change position, and clinicians because of the heavy workload, many things can not be done in time dressing. 持续渗液的伤口不仅容易引起患者感染,还使患者有湿冷、肮脏的感觉,同时由于湿透的伤口敷料粘性差,较易脱落,患者不敢随意更换体位,躯体处于僵硬状态,不仅影响患者休息还容易发生压疮事件,频繁更换伤口敷料增加医护人员工作量和患者经济负担。 Continuous wound exudate is not only easy to cause infection in patients, so that patients also have a wet, dirty feeling, and because wet wound dressing viscous, easier to fall off, the patient can not arbitrarily change position, the body in a stiff state, not only affects the patients rest also prone to pressure sores events, frequently changing wound dressings increase the workload of medical and economic burden on patients.

[0004] 2、造口袋:此方法可以将外渗液引流到造口袋内,避免外渗液污染患者衣服和床单,减少了医护人员的工作量,让患者感觉相对舒适。 [0004] 2, ostomy bag: This method can be outside exudate drainage into the ostomy bag, to avoid contamination of patients outside exudate clothes and bed sheets, reducing the workload of medical staff, so that patients feel relatively comfortable. 但此方法解决不了伤口渗液的根本问题,外渗液会因患者更换体位随时渗出,伤口长期处渗液状态,致使伤口不能愈合。 However, this method does not solve the fundamental problem of wound exudate, exudate outside because of patient change position at any time oozing wound exudate at the long-term status, resulting in a wound can not heal. 长时间的渗液不仅增加患者心理负担还容易引发患者感染。 Long exudate not only increase the psychological burden of patients also easily lead to infection in patients.

[0005] 3、液体胶(耳脑胶):该药物开封后要及时使用,不然会自然凝固。 [0005] 3, liquid glue (glue ear brain): the drug must be promptly used after opening, or naturally solidified. 为一次性耗材品,规格较大,但使用剂量却不多,每次只需几滴,剩余量容易浪费,且价格昂贵,不进医保。 Disposable supplies for the product, the bigger size, but dose not many, just a few drops each time, the remaining amount of waste is easy, and expensive, not into Medicare. 该药物在粘补伤口时,因为是液体结构,不易被控制,往往会粘到周围皮肤,尤其是在皮肤褶皱处,容易导致上下皮肤粘连不易分开。 When the drug stick wound up, since the structure is a liquid, can not easily be controlled, it will often stick to the surrounding skin, in particular skin folds, up and down easily lead to skin adhesion not easy to separate. 对肝硬化伴顽固性腹水的患者来说,因穿刺口持续性渗液,在液体胶还没有完全变成固体时,往往已被腹水稀释或随着腹水渗出而流失,止液效果不理想。 For patients with refractory cirrhotic ascites, exudate sustained by the puncture, when the liquid adhesive has not completely become solid, ascites dilution often has been the loss or bleeding as ascites, was not effective stop .

[0006] 4、橡皮塞:是临床上采用的一个小技巧。 [0006] 4, the rubber stopper: It is a trick used clinically. 将软橡皮塞对准伤口,然后按压橡皮塞顶部,在橡皮塞回弹的时候用医用纸胶把软橡皮塞固定住,约48小时后取下,查看伤口愈合情况。 Soft rubber plug align the wound, and then pressing the top of the rubber stopper, the soft plastic sheet with medical rubber stopper when the rubber stopper fixed springback, removed after about 48 hours, see wound healing. 此方法简单实用,效果明显,但缺点也很多。 This method is simple and practical, the effect is obvious, but there are many shortcomings. 首先,因患者的伤口位置各有不同,橡皮塞的妥善固定就存在问题。 First, because the wound position of the patient is different, properly secured to the rubber stopper of a problem. 对于邻近关节部位的伤口橡皮塞往往不易被固定,密封性差,容易发生血液、体液外漏。 To the adjacent joints often difficult to be wound rubber stopper fixed, poor sealing, prone to blood, body fluid leakage. 对于经常被摩擦到的部位,即便是用纸胶妥善固定,在患者不经意地碰触或更换更换体位时也容易发生橡皮塞移位或滑脱,导致血液、体液外漏。 For often friction to the site, even if the adhesive sheet properly secured to inadvertently touch or replace the rubber stopper is also prone to slipping replacement or displacement position in the patient, leading to blood, body fluid leakage. 长时间反复用纸胶固定,容易造成患者皮肤受损。 Prolonged and repeated paper glue, the patient likely to cause skin damage. 其次,因橡皮塞为不透明材质,肉眼看不到伤口的愈合情况,只能根据经验在48小时左右取下橡皮塞查看伤口愈合情况,然后决定是否继续治疗。 Secondly, because the rubber stopper opaque material, the naked eye can not see the healing of the wound, remove the rubber plug can only see the wound healing in about 48 hours based on experience, and then decide whether to continue treatment. 由此一来,不仅不能正确判断伤口愈合情况,还可能因长时间的压迫造成伤口周围皮肤坏死而不被发现。 As a result, not only can not correctly determine wound healing, it may also cause necrosis of the skin surrounding the wound for a long time without being detected oppression. 再者,橡皮塞为就地取材,没有严格的消毒处理,容易导致伤口感染。 Furthermore, the rubber stopper to make the best, there is no strict disinfection, easily lead to wound infection.
