Abstract
The invention discloses a liquid stopping buoy of an automatic liquid stopping infusion device; the liquid stopping buoy comprises a column-shaped liquid stopping buoy main body and a mounting groove which is formed in the bottom of the liquid stopping buoy main body, wherein a liquid stopping film is embedded in the mounting groove; the mounting groove of the liquid stopping buoy main body is shaped like a circular platform, which is bigger inside and smaller outside; and the top of the liquid stopping film is open, the bottom of the liquid stopping film is sealed, and the side wall of the liquid stopping film is matched with the mounting groove. A plurality of gas exhaust grooves are formed in the side wall of the mounting groove. The liquid stopping buoy disclosed by the invention has the advantages as follows: (1) through the design of the gas exhaust grooves, air between the liquid stopping film and the mounting groove is exhausted, so that the liquid stopping film is easy to be mounted in the mounting groove; (2) through the design of the gas exhaust grooves, medicine liquor stays in a groove above the liquid stopping film, so that the mass of the liquid stopping buoy is increased; therefore, the liquid stopping buoy can cover a pipe opening of a dropping pipette in a sealed way; (3) the liquid stopping buoy is effectively prevented from being clamped on a stopping gate; and (4) the liquid stopping film is uneasy to fall off.
Description
Technical field
The present invention relates to a kind of liquid buoy that ends, be specially a kind of only liquid buoy of automatic liquid-stopping infusion set, belong to technical field of medical instruments.
Background technology
Transfusion device is one of hospital's medical apparatus and instruments commonly used, is mainly used in the gravity type venous transfusion.Generally be to be connected to form by intravenous needle, helmet, infusion tube, liquid medicine filter, flow regulator, a kettle assembly, bottle plug puncture unit, air inlet pipe air filter.Under atmospheric effect, the liquid runs down infusion tube flows into and drips kettle in the bottle, and when dripping the kettle water column pressure greater than venous pressure, the liquid runs down flexible pipe in the bottle flows into passages through which vital energy circulates.
Dripping kettle mechanism and generally be comprised of two parts chamber up and down, be up and down isolated gate between two parts cavity, and a minim pipette runs through and drips the kettle bottom, is communicated with inside and outside the kettle; At the bottom of interior part exceeded a kettle, part outside was connected with infusion tube; One column is set in the described lower chamber ends the liquid buoy, end position corresponding with the minim pipette that drips the kettle bottom on the liquid buoy and be provided with only liquid film.
There are some defectives in this liquid buoy that ends: 1, owing to form comparatively airtight air chamber between barrier film and the mounting groove that ends the liquid buoy, be not easy installation; 2, owing to end liquid buoy lighter weight, often when medicinal liquid drips off, can not be overlying on very hermetically the mouth of pipe of minim pipette; 3, when medicinal liquid is more, only the liquid buoy floats and is against on the backstop grid, is stuck in sometimes on the backstop grid; 4, barrier film in use comes off easily.
Summary of the invention
The invention discloses a kind of only liquid buoy of automatic liquid-stopping infusion set, to solve the problems referred to above of prior art.
Purpose of the present invention can be achieved through the following technical solutions.
A kind of only liquid buoy of automatic liquid-stopping infusion set comprises that column is ended liquid buoy main body and at the mounting groove that ends the setting of liquid buoy bottom part body, is embedded only liquid film in the mounting groove; The described mounting groove that ends liquid buoy main body is interior large outer little round table-like; Described liquid film open top, bottom lock and sidewall and the mounting groove coupling of ending.
Be provided with some air discharge ducts on the described mounting groove sidewall.On the one hand, end liquid film when being installed to mounting groove, only air is discharged by air discharge duct between liquid film and the mounting groove, thereby is convenient to install; On the other hand, in the use procedure, medicinal liquid injects by air discharge duct and ends liquid film, owing to end the bowl-shape design of liquid film, medicinal liquid is retained in only liquid film top, has increased the weight of ending the liquid buoy, therefore when medicinal liquid drips off, can be overlying on very hermetically on the dropping liquid post.
Be provided with on the described sidewall that ends liquid buoy main body and be no less than three external tooth, on the one hand medicinal liquid is passed through smoothly, can reduce on the other hand only liquid buoy and the friction of dripping between the kettle wall, so that only the liquid buoy is floating and sinking all very sensitive.
The external tooth of described only liquid buoy is 0.5-2.0mm to the average distance of dropping funnel inwall.
Described top of ending the liquid buoy is provided with spherical crown shape projection, prevents that only the liquid buoy is stuck on the backstop grid.
Only liquid buoy by the present invention designs has following beneficial effect:
1, the design by air discharge duct so that end Bas Discharged between liquid film and the mounting groove, will end easily liquid film and be installed into mounting groove;
2, by the design of air discharge duct, medicinal liquid rests in the groove that ends the liquid film top, has increased the quality of ending the liquid buoy, therefore can be overlying on hermetically the mouth of pipe of minim pipette;
3, prevented that effectively only the liquid buoy is stuck in the backstop grid;
4, end the liquid film difficult drop-off.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of inversion state of the present invention
(figure ends liquid film and separates with mounting groove);
Among the figure: 1, end liquid buoy main body 2, mounting groove 3, end liquid film 4, air discharge duct 5, external tooth 6, spherical crown shape projection.
The specific embodiment
Further set forth construction features of the present invention below in conjunction with accompanying drawing and specific embodiment.
As depicted in figs. 1 and 2, a kind of only liquid buoy of automatic liquid-stopping infusion set comprises that column is ended liquid buoy main body 1 and at the mounting groove 2 that ends the setting of liquid buoy main body 1 bottom, is embedded only liquid film 3 in the mounting groove 2; The described mounting groove 2 that ends liquid buoy main body 1 be interior little round table-like greatly outward; Described liquid film 3 open tops, bottom lock and sidewall and mounting groove 4 couplings of ending.
Be provided with some air discharge ducts 4 on described mounting groove 2 sidewalls.On the one hand, end liquid film 3 when being installed to mounting groove 4, only air is discharged by air discharge duct 4 between liquid film 3 and the mounting groove 2, thereby is convenient to install; On the other hand, in the use procedure, medicinal liquid injects by air discharge duct 4 and ends liquid film 3, owing to end the bowl-shape design of liquid film 3, medicinal liquid is retained in only liquid film 3 tops, has increased the weight of ending the liquid buoy, therefore when medicinal liquid drips off, can be overlying on very hermetically on the dropping liquid post.
Be provided with the external tooth 5 that is no less than three on the sidewall of described only liquid buoy main body 1, on the one hand medicinal liquid passed through smoothly, can reduce on the other hand the friction that ends between liquid buoy and the kettle wall, floating and sinking all very sensitive so that end the liquid buoy.
The external tooth 5 of described only liquid buoy is 0.5-2.0mm to the average distance of dropping funnel inwall.
Described top of ending liquid buoy main body 1 is provided with a spherical crown shape projection 6, prevents that only the liquid buoy is stuck on the backstop grid.
