Abstract
The utility model discloses a soup self-closing tool, comprising a casing. The upper portion of the casing is provided with a liquid inlet hole, the lower portion is provided with a liquid outlet hole, a floating spool is arranged in the casing, the lower face of the floating spool is closely fitted with the face of the liquid outlet hole, the floating spool is a flat self-closing film, the lower surface of the flat self-closing film is a plane, the floor of the casing which is fitted with the lower surface of the flat self-closing film and is provided with the liquid outlet hole is a plane. The floating spool can be a ball, the liquid outlet hole is a concave spherical surface which is fitted with the ball, or the floating spool can be tundish-shaped, the length of the tundish is longer than the height of an inner cavity of the casing. The casing is divided into an upper casing and a lower casing, a filter web is arranged between the upper casing and the lower casing, the upper casing is clipped with the lower casing, the filter web is composed of two concentric circles which are connected by four tendons which are in decussation positions. The floating spool of the utility model can automatically close the liquid outlet hole, then the whole passage of a transfusion tool is closed, thereby avoid the back flowing of blood. The utility model has the advantages of simple structure, safety, reliability, convenience, practicability, and is labor-saving, time-saving.
Description
Technical field
This utility model relates to a kind of transfusion device that medicinal liquid is used of importing, and specifically is the self-closing device of medicinal liquid.
Background technology
At present, the transfusion device that people use in hospital is generally after medicinal liquid is totally lost, if medical personnel are absent from the scene or when in time not closing (or being not closed completely) transfusion device control valve, will cause the blood back phenomenon, the life security that also will jeopardize the patient when serious.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, even this utility model provides a kind of not close transfusion device control valve also can not cause the self-closing device of medicinal liquid of blood back phenomenon.
For achieving the above object, the self-closing device of medicinal liquid of the present utility model is made of housing, and housing top is provided with inlet, and the bottom is provided with liquid outlet, is floating spool in the housing, and floating spool bottom surfaces cooperates with the fluid actinal surface is airtight.
Described floating spool is dull and stereotyped self-closing film, and floating spool bottom surfaces is meant that with airtight cooperation of liquid outlet self-closing film lower surface is the plane, and the housing bottom surface that liquid outlet is set of matching with self-closing film lower surface is the plane, and two planes stick together and constitute airtight cooperation.
Described floating spool is a ball, and liquid outlet is the concave spherical surface that cooperates with ball.
The shape of described floating spool is a funnel-form, and the length of its funnel is greater than the lower housing cavity height.
Housing is divided into lower house, between the last lower house drainage screen is set, last lower house clamping.
Described drainage screen is that two concentric circulars join according to four decussation muscle.
After adopting such structure, described floating spool is meant in medicinal liquid can buoyant spool, owing in the self-closing device housing of medicinal liquid, be provided with floating spool, during transfusion, floating spool levitating, lower liquid outlet is unimpeded, after medicinal liquid is totally lost, even medical personnel are absent from the scene or when not needing the close transfusion device control valve, the floating spool of this utility model inside can be closed the medicinal liquid liquid outlet automatically, makes whole transfusion device passage airtight, is unlikely and causes the blood back phenomenon, and it is simple in structure, safe and reliable, convenient simple and easy, practical, time saving and energy saving people from province is existing with the not available function of transfusion device.

The specific embodiment
Constitute by housing 2 as Fig. 1, Fig. 2, the self-closing device of medicinal liquid shown in Figure 4, housing 2 tops are provided with inlet 1, the bottom is provided with liquid outlet 5, floating spool in the housing 1 is dull and stereotyped self-closing film 4, dull and stereotyped self-closing film 4 lower surfaces are planes, and the housing bottom surface that liquid outlet 5 is set of matching with the self-closing film lower surface of flat board is that two planes, plane stick together the airtight cooperation of formation.Housing is divided into lower house, and drainage screen 2 is set between the last lower house, last lower house clamping.
The inlet 1 of the self-closing device upper shell of medicinal liquid 2-1 links to each other with the utensil (ware) of transfusion bottle or Sheng medicinal liquid by conduit or latex tubing, the liquid outlet 5 of the self-closing device lower house of medicinal liquid 2-2 is connected with the transfusion device water dropper by conduit or latex tubing, when human body need be imported medicinal liquid, medicinal liquid flows in the inner chamber of the self-closing device upper shell of medicinal liquid 2-1 by inlet 1, in inner chamber through the self-closing device lower house of inflow medicinal liquid 2-2 after the filtration of drainage screen 3, medicinal liquid fashionablely just can make the dull and stereotyped self-closing film 4 in the self-closing device lower house of the medicinal liquid 2-2 floating continuing to flow, medicinal liquid is imported human body by the liquid outlet inflow catheter through the transfusion device water dropper like this, and after medicinal liquid is totally lost, flat board closes film 4 and just falls the liquid outlet 5 that gets lodged in the self-closing device lower casing of medicinal liquid 2-2 again, the sealing liquid outlet, so just make whole transfusion device pathway closure, the blood back phenomenon occurs even medical personnel are absent from the scene also to be unlikely.
At least one face of housing bottom surface of self-closing film lower surface and liquid outlet is a smooth flat; One of the housing bottom surface of self-closing film lower surface and liquid outlet is a smooth flat, and the stricture of vagina reason is set on another plane; The housing bottom surface of self-closing film lower surface and liquid outlet is smooth flat; The housing bottom surface of self-closing film lower surface and liquid outlet is texture.
The housing of present embodiment can be an integral body, because other position can be provided with drainage screen, this utility model also can not be provided with drainage screen.
As Fig. 2, Fig. 3, shown in Figure 5, floating in the present embodiment spool is a ball 6, liquid outlet 5 is the concave spherical surfaces that cooperate with ball, the inwall of the self-closing device lower house of medicinal liquid 2-2 inner chamber is that certain gradient is arranged, like this when medicinal liquid flows to end, ball falls and cooperates the sealing liquid outlet with concave spherical surface, and other structure and work process are same as the previously described embodiments.
As Fig. 2, Fig. 3, shown in Figure 6, the shape of floating spool is a funnel-form 7 in the present embodiment, the length of its funnel is greater than the lower housing cavity height, liquid outlet 5 is the inclined-planes that match with the funnel-form spool, medicinal liquid is when flowing to end like this, the funnel-form spool falls and cooperates the sealing liquid outlet with the inclined-plane, and other structure and work process are same as the previously described embodiments.
