Description

自动停止输液器Automatic stop infusion set

技术领域 technical field

本发明属于医疗器械，具体的涉及一种自动停止输液器。 The invention belongs to medical equipment, in particular to an automatic stop transfusion device.

背景技术 Background technique

目前，静脉输液是临床治疗的主要手段之一，也是护士每天的日常工作，基本手工操作，护士工作量大，劳动强度大 ，操作中因为疲劳，不能规范操作，造成重大后果的情况也会出现，最好有智能、自动输液器为护士使用。 At present, intravenous infusion is one of the main means of clinical treatment, and it is also the daily work of nurses. The basic manual operation, nurses have a large workload and labor intensity. Due to fatigue during the operation, the operation cannot be standardized, causing major consequences. , it is best to have an intelligent, automatic infusion set for nurses to use.

发明内容 Contents of the invention

本发明的目的在于提供一种自动停止输液器，该输液器能够自动、准确地将输液工作随药液的流完而停止，减轻护士的劳动强度。 The purpose of the present invention is to provide an automatic stop infusion device, which can automatically and accurately stop the infusion work when the liquid medicine is finished, so as to reduce the labor intensity of nurses.

本发明的目的及解决其主要技术问题是采用以下技 Purpose of the present invention and its main technical problem that solves are to adopt following technology

术方案来实现的：一种自动停止输液器，包括积液袋，积液袋上有进水口和出水口，积液袋内设支杆，支杆通过销钉连接在固定架上，密封球装在出水口上与支杆连接，支杆的另一端固定漏斗，漏斗下有小孔，漏斗上对着进水口。 It is realized by the operation plan: an automatic stop infusion device, including a fluid bag, a water inlet and a water outlet on the fluid bag, a strut is arranged in the fluid bag, the strut is connected to the fixed frame by a pin, and the sealed ball is installed. The water outlet is connected with the support rod, the other end of the support rod is fixed with a funnel, there is a small hole under the funnel, and the funnel faces the water inlet.

所述密封球的重量大于漏斗，漏斗加满液的重量大于密封球的重量。 The weight of the sealing ball is greater than that of the funnel, and the weight of the filling liquid of the funnel is greater than the weight of the sealing ball.

本发明工作原理： The working principle of the present invention:

由于支杆通过销钉连接在固定架上，密封球的重量稍微大于漏斗，所以在没有工作的时候密封球压在出水口上；药液通过进水口流进腔体，滴到漏斗里，由于小孔较小，从小孔中流出药液的速度小于进水口进药液的速度，就会在盛满后溢出来，此时，漏斗端重量大于密封球端，密封球被抬起来，药液从出水口流出去。当瓶中的药液用完，进水口停止进药液，小孔就会慢慢将漏斗中的药液滴完，此时密封球端重量大于漏斗端，密封球下降，将出水口密封，药液停止流动。 Since the rod is connected to the fixed frame by pins, the weight of the sealing ball is slightly larger than that of the funnel, so the sealing ball is pressed against the water outlet when there is no work; the liquid medicine flows into the cavity through the water inlet and drips into the funnel. The hole is small, and the speed of liquid medicine flowing out from the small hole is lower than the speed of liquid medicine entering the water inlet, and it will overflow after it is full. Flow out from the outlet. When the liquid medicine in the bottle is used up, the water inlet stops feeding the liquid medicine, and the small hole will slowly drop the medicine liquid in the funnel. At this time, the weight of the sealing ball end is greater than that of the funnel end, and the sealing ball descends to seal the water outlet. The medicine stops flowing.

本发明与现有技术相比具有明显的优点和有益效果。由以上技术方案可知，本发明能够自动、准确地将输液工作随药液的流完而停止，减轻护士的劳动强度。 Compared with the prior art, the present invention has obvious advantages and beneficial effects. It can be known from the above technical solutions that the present invention can automatically and accurately stop the infusion work when the liquid medicine is finished, reducing the labor intensity of nurses.

具体实施方式 Detailed ways

下面结合附图和较佳实施例，对依据本发明提出的自动停止输液器具体实施方式、特征及其功效，详细说明如后。 The specific implementation, features and effects of the automatic stop infusion set proposed according to the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

参见图1，一种自动停止输液器，包括积液袋，积液袋上有进水口1和出水口7，积液袋内设支杆5，支杆5通过销钉4连接在固定架8上，密封球6装在出水口7上与支杆5连接，支杆5的另一端固定漏斗2，漏斗2下有小孔3，漏斗2上对着进水口1。 Referring to Fig. 1 , an automatic stop infusion set includes a effusion bag with a water inlet 1 and a water outlet 7 on the effusion bag, and a strut 5 is arranged inside the effusion bag, and the strut 5 is connected to a fixed frame 8 through a pin 4 , sealing ball 6 is contained in water outlet 7 and is connected with pole 5, and the other end of pole 5 is fixed funnel 2, and aperture 3 is arranged under funnel 2, and on funnel 2, faces water inlet 1.

所述密封球6的重量大于漏斗2，漏斗2加满液的重量大于密封球6的重量。 The weight of the sealing ball 6 is greater than that of the funnel 2, and the weight of the liquid filled in the funnel 2 is greater than the weight of the sealing ball 6.

本发明工作原理： The working principle of the present invention:

由于支杆5通过销钉4连接在固定架8上，密封球6的重量稍微大于漏斗2，所以在没有工作的时候密封球6压在出水口7上；药液通过进水口1流进腔体，滴到漏斗2里，由于小孔3较小，从小孔3中流出药液的速度小于进水口1进药液的速度，就会在盛满后溢出来，此时，漏斗端重量大于密封球端，密封球6被抬起来，药液从出水口7流出去。当瓶中的药液用完，进水口1停止进药液，小孔3就会慢慢将漏斗2中的药液滴完，此时密封球端重量大于漏斗端，密封球6下降，将出水口7密封，药液停止流动。 Since the strut 5 is connected to the fixed frame 8 through the pin 4, the weight of the sealing ball 6 is slightly larger than that of the funnel 2, so the sealing ball 6 is pressed on the water outlet 7 when there is no work; the liquid medicine flows into the cavity through the water inlet 1 , drops into the funnel 2, because the small hole 3 is small, the speed of the liquid medicine flowing out from the small hole 3 is lower than the speed of the liquid medicine entering the water inlet 1, and it will overflow after it is full. At this time, the weight of the funnel end is greater than The sealing ball end, the sealing ball 6 is lifted, and the medicinal liquid flows out from the water outlet 7. When the medicinal solution in the bottle is used up, the water inlet 1 stops feeding the medicinal solution, and the small hole 3 will slowly drop the medicinal solution in the funnel 2. At this time, the weight of the sealing ball end is greater than that of the funnel end, and the sealing ball 6 descends, and the The water outlet 7 is sealed, and the medicinal liquid stops flowing.

本发明能够自动、准确地将输液工作随药液的流完而停止，减轻护士的劳动强度。 The invention can automatically and accurately stop the infusion work when the liquid medicine is finished, thereby reducing the labor intensity of nurses.

 以上所述，仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，任何未脱离本发明技术方案内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。 The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Any simple modification, Equivalent changes and modifications still fall within the scope of the technical solution of the present invention.
