Embodiment 1

[0046] The overall structure of a specific embodiment of the present invention, with reference to the prior art figure 1 As shown, at least one liquid stop member 20 that can float in the dropping funnel 10 is included. The dropping funnel 10 also has a liquid inlet 13 for introducing the dripping liquid L, and a dripping liquid outlet 12 .

[0047] Such as Figure 4 , Figure 5 As shown, the liquid stop component 20 in this embodiment at least includes a hermetic floating body 22 and a spherical membrane unit 23 which are fixedly connected. The airtight floating body 22 is used to provide the buoyancy to make the liquid stop member 20 float up, and the spherical film unit 23 has the function of closing the droplet outlet 12 to stop the liquid.

[0048] In the present invention, an anti-clogging structure is also provided between the liquid stop member 20 and the liquid inlet portion 13 . In this embodiment, the anti-clogging structure is arranged between the top surface 2...

Embodiment 2

[0053] Such as Figure 10 , Figure 11 As shown, the structure of this embodiment is basically the same as that of Embodiment 1. The liquid-stopping component 20 at least includes an airtight floating body 22 and a spherical membrane unit 23 fixedly connected, and the anti-clogging structure is arranged on the top surface 212 of the airtight floating body 22 and Between the liquid inlet parts 13.

[0054] The difference is that the anti-clogging structure in this embodiment is a drainage groove 213 provided on the top surface 212 of the liquid-stop component 20 . The shape of the orthographic projection of the drainage groove 213 should be different from the cross-sectional shape of the liquid inlet part 13, so that at least one liquid channel can be formed between the two when the two are abutted against each other for dripping liquid to go down.

[0055] Specifically, when the cross section of the liquid inlet portion 13 is circular as shown in this embodiment, in differen...

Embodiment 3

[0059] The structure of this embodiment is basically the same as that of Embodiment 2, except that the anti-clogging structure in this embodiment is at least one through hole (not shown) opened on the top surface 212 of the liquid-stop component 20 .

[0060] The positions of the inlet end and the outlet end of the through hole need to be specially set. That is, the inlet end of the through hole must communicate with the liquid inlet 13, and the outlet end of the through hole must communicate with the cavity of the dropping funnel 10, and the through hole itself does not destroy the sealing of the airtight floating body 22.

[0061] In this way, with the help of the drainage channel formed between the liquid inlet part 13 and the inner cavity of the drip storage tube 10 by means of the through hole, the smooth downward flow of the drip can be realized.

Abstract

The invention discloses a liquid stopping control device of a drop infusion apparatus, at least comprising a liquid stopping part, the liquid stopping part can float in a dropping funnel; the dropping funnel is also provided with a liquid inlet part for guiding dropping liquid; and an anti-blocking structure is arranged between the liquid stopping part and the liquid inlet part. By adopting the structure, the invention effectively prevents the condition that the dropping liquid can not downwards flow because the liquid stopping part blocks the liquid inlet part by arranging the anti-blocking structure between the liquid stopping part and the liquid inlet part, thereby reducing the operation troubles of medical workers; compared with the prior art, liquid stopping control device of the drop infusion apparatus has greatly enhanced convenience and economic benefit on operation and member manufacture and assembly cost.

Description

technical field [0001] The invention relates to the technical field of drip transfusion devices, in particular to a liquid stop control device for drip transfusion devices. Background technique [0002] At present, clinically, in the drip transfusion process for medical treatment of patients, drip infusion sets with flow controllers and liquid stop control devices are widely used. [0003] Such as figure 1 As shown, it is a drip infusion set in the prior art, mainly including a dripping funnel 10, and a pointed joint 60 arranged above the dripping funnel 10 and communicating with it. The lower part of the dropping funnel 10 is provided with a droplet outlet 12, and is connected to a draft tube 11 through the droplet outlet 12. A flow controller 40 is arranged in series in the guide tube 11 , and a needle 50 is connected to the end of the guide tube 11 . [0004] In the implementation of drip infusion operation, pointed connector 60 is used to be inserted in the drip bottl...
