Abstract
The utility model discloses an automatic liquid stopping exhaust device for an infusion set, which comprises an upper liquid medicine filter cover (1) and a lower liquid medicine filter cover (2). A liquid inlet (3) is arranged on the upper liquid medicine filter cover (1), a liquid outlet (4) is arranged on the lower surface of the lower liquid medicine filter cover (2), a filter liquid stopping membrane (5) is arranged between the upper liquid medicine filter cover (1) and the lower liquid medicine filter cover (2), an exhaust pipe (6) is arranged on the upper liquid medicine filter cover (1), the outer end of the exhaust pipe (6) is communicated with the outside, the inner end of the exhaust pipe (6) is communicated with the inside of the upper liquid medicine filter cover (1) and spaced from the filter liquid stopping membrane (5), and a gas-permeable water-stopping membrane (7) is arranged at the inner end of the exhaust pipe (6). The gas-permeable water-stopping membrane allows gas to permeate while preventing liquid from permeating, so that the exhaust pipe is capable of exhausting the gas while preventing liquid medicines from flowing out, and then bubbles can be prevented. Simultaneously, gas circulation in a drip chamber is benefited, and the liquid medicines can be smoothly discharged from the drip chamber conveniently.
Description
Technical field
This utility model relates to the parts that a kind of transfusion device is used, and specifically is meant the automatic solution stopping exhaust apparatus of a kind of transfusion device.
Background technology
At present, transfusion device is a kind of medical apparatus and instruments, and it gives human body with the treatment disease medicinal liquid infusion through intravenous drip.Transfusion device of the prior art in use is easy to generate bubble, and in addition, because the gas circulation in the dropping funnel is not good, medicinal liquid is discharged and also had some setbacks.
Therefore, a kind of bubble that can prevent to produce is provided, also helps the gas circulation in the dropping funnel simultaneously, being convenient to the smooth automatic solution stopping exhaust apparatus of transfusion device of discharging of medicinal liquid becomes the industry technical issues that need to address.
The utility model content
This utility model technical issues that need to address are to provide a kind of bubble that can prevent to produce, and also help the gas circulation in the dropping funnel simultaneously, are convenient to the automatic solution stopping exhaust apparatus of transfusion device that medicinal liquid is discharged smoothly.
For solving the problems of the technologies described above; The technical scheme that this utility model adopts is: the automatic solution stopping exhaust apparatus of transfusion device, comprise liquid medicine filter loam cake and liquid medicine filter lower cover, and cover on the liquid medicine filter and be provided with liquid inlet; Be provided with liquid outlet below the liquid medicine filter lower cover; Be provided with between liquid medicine filter loam cake and the liquid medicine filter lower cover and filter the solution stopping film, be provided with exhaustor above the described liquid medicine filter loam cake, the exhaustor outer end is in communication with the outside; Inner and liquid medicine filter loam cake internal communication and and filter and keep between the solution stopping film at interval, exhaustor the inner is provided with the film that blocks water of breathing freely.
The outer end of described exhaustor is provided with air lock.
Cover on the described liquid medicine filter and be provided with liquid-feeding tube, the liquid-feeding tube outer end is provided with the latex plug.
Be respectively equipped with the fixed mount of clamping filtration solution stopping film above the bottom surface of described liquid medicine filter loam cake and the liquid medicine filter lower cover.
Owing to adopted above-mentioned structure; The ventilative film that blocks water of this utility model allows gas permeation and prevents that liquid from seeing through; Therefore exhaustor is preventing that the effusive while of medicinal liquid from can play scavenging action; Can prevent to produce bubble like this, also help the gas circulation in the dropping funnel simultaneously, be convenient to medicinal liquid and discharge smoothly.This utility model is simple in structure, has very strong practicality and promotional value.
Description of drawings
Fig. 1 is the cutaway view of the automatic solution stopping exhaust apparatus of transfusion device.
The specific embodiment
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing this utility model.
As shown in Figure 1, the automatic solution stopping exhaust apparatus of the described transfusion device of this utility model comprises liquid medicine filter loam cake 1 and liquid medicine filter lower cover 2.Liquid medicine filter loam cake 1 is provided with liquid inlet 3, and liquid inlet 3 is used to be communicated with transfusion catheter.Be provided with liquid outlet 4 below the liquid medicine filter lower cover 2, liquid outlet 4 is used to be communicated with dropping funnel.Be provided with between liquid medicine filter loam cake 1 and the liquid medicine filter lower cover 2 and filter solution stopping film 5; Filter solution stopping film 5 and mainly play the solution stopping effect; It can play the certain delay effect, when medicinal liquid is totally lost soon, diminishes and liquid is filtering under the tensile combined effect on the solution stopping film at fluid pressure; It is slack-off to filter solution stopping film 5 filtering speed, can stop infusing or changes medicine bottle and bring certain buffer time to medical personnel.Filter solution stopping film 5 and also can be secondary filter solution stopping film, to be used for the particulate matter in infusion process filtering medicinal liquid.Be provided with exhaustor 6 above the described liquid medicine filter loam cake 1, exhaustor 6 outer ends are in communication with the outside, inner and liquid medicine filter loam cake 1 internal communication and and filter and keep between the solution stopping film 5 at interval, exhaustor 6 the inners are provided with the film 7 that blocks water of breathing freely.The ventilative film 7 that blocks water allows gas permeations and prevents that liquid from seeing through, so exhaustor 6 can prevent to produce bubble preventing that the effusive while of medicinal liquid from can play scavenging action, also helps the gas circulation in the dropping funnel simultaneously, is convenient to medicinal liquid and discharges smoothly.
The outer end of described exhaustor 6 is provided with air lock 8, opens when air lock 8 is to use, and the time spent does not clog the outer end of exhaustor 6, prevents to pollute.
Described liquid medicine filter loam cake 1 is provided with liquid-feeding tube 9, and liquid-feeding tube 9 outer ends are provided with latex plug 10, medicine-adding infusion when liquid-feeding tube 9 is used to infuse.
Be respectively equipped with the fixed mount 11 of clamping filtration solution stopping film 5 above the bottom surface of described liquid medicine filter loam cake 1 and the liquid medicine filter lower cover 2; Fixed mount 11 can play the effect that clamping filters solution stopping film 5; Liquid outlet 4 and liquid inlet 3 interior end openings are kept at a distance with filtering solution stopping film 5 respectively, be convenient to filter solution stopping film 5 and play one's part to the full.
In a word; The above-mentioned preferred implementation though this utility model has been given an example; But should explain; Though those skilled in the art can carry out various variations and remodeling,, otherwise all should be included in the protection domain of this utility model only if such variation and remodeling have departed from the scope of this utility model.
