Abstract
The invention discloses an automatic exhaust half-full transfusion system liquid-filter-storage dropping bottle. A transfusion system dropping bottle with an exhaust window comprises a dropping bottle cover, a dropping bottle hopper, an exhaust film, an exhaust film gland and a microporous film, wherein the dropping bottle cover and the dropping bottle hopper are in butt joint and are sealed to form a dropping bottle shell, liquid flows to the dropping bottle hopper from the dropping bottle cover, the side wall of the dropping bottle shell is provided with an exhaust hole, the exhaust film is covered on the exhaust hole on the side wall of the dropping bottle shell, and the microporous film is arranged at the downstream of the exhaust hole on the side wall of the dropping bottle shell; and when the bottle is used, the liquid can enter into the dropping bottle without operating the dropping bottle and can automatically reach to the position of the exhaust window on the middle part, in addition, the liquid can be retained under the microporous film in the dropping bottle through the hydrophilic tension of the microporous film after the liquid is drained, so the pressure can be prevented from being further reduced due to the drainage of the liquid, as the pressure of liquid medicine, the phenomenon that blood in blood vessel flows back to the transfer tube to cause blood coagulation is avoided, when transfusion is performed again, liquid medicine is full again to reach to the first liquid level, meanwhile the filtration of the liquid medicine is also realized. The bottle brings more convenience for operating personnel, and also is safer to use for patient.
Description
Technical field
The present invention relates to filter the liquid storage drop bottle from aerofluxus half full transfusion device.Particularly relate to a kind of transfusion device drop bottle that has exhausting window, can not operate drop bottle during use and just can realize that liquid enters drop bottle and the automatic exhausting window position that arrives the middle part, in liquid is walked empty back drop bottle, rely on the hydrophilic tension force of microporous membrane to make liquid still keep below the microporous membrane in addition, prevent that liquid emptying and pressure from further reducing.Because the pressure of medicinal liquid is arranged, avoid the vessel inner blood backflow to enter tube for transfusion and caused blood coagulation, when infusing once more, liquid can fill microporous membrane and the medicinal liquid automatic butt of last time once more, realizes the filtration to medicinal liquid simultaneously.The more convenient operator of this device are also safer for the patient.
Technical background
At present, the transfusion device drop bottle of all uses all can not aerofluxus, the plane of medicinal liquid produces negative pressure by the soft drop bottle of manual compression, attract the interior medicinal liquid of the medicinal fluid bag (bottle) on top dirty and finish, the operating time of incuring loss through delay other is in addition because difference in operation may form the tube for transfusion that bubble enters the drop bottle downstream; After liquid input finished, liquid level will reduce, and until vascular site, be very easy to cause blood to reflux to enter cause in the tube for transfusion and solidify and stops up, if during infusing, must the replacing transfusion device, bring a lot of inconvenience and delay treatment.
Summary of the invention
In order to solve above-mentioned existing in prior technology defective, the invention provides a kind of from aerofluxus half full transfusion device filtration liquid storage drop bottle, comprise drop bottle cover, drop bottle funnel, exhaust membrane, exhaust membrane gland and microporous membrane, drop bottle cover and drop bottle funnel Butt sealing constitute the drop bottle shell, liquid flows to the drop bottle funnel from the drop bottle cover, the drop bottle shell side wall has vent openings, and exhaust membrane covers on the vent openings of drop bottle shell side wall, and microporous membrane is installed in the downstream of drop bottle shell side wall vent openings; The position of microporous membrane is positioned on the downstream position of drop bottle shell side wall vent openings, and promptly the horizontal level of microporous membrane is lower than the horizontal level of drop bottle shell side wall vent openings; The exhaust membrane sealing covers the vent openings outside of drop bottle shell side wall, and the edge of exhaust membrane is glanded to overlay and is sealed on the drop bottle shell; The hard material manufacturing of drop bottle funnel, the heat seal of microporous membrane edge are sealed on the edge of this hard drop bottle funnel correspondence suitable for reading; The aperture of microporous membrane is between 0.01 micron to 14 microns, and microporous membrane is the water wetted material manufacturing; The top edge of drop bottle shell side wall vent openings is positioned at the approximate center of drop bottle, i.e. liquid level position; Drop bottle cover and drop bottle funnel are all used the hard material manufacturing, and both Butt sealings constitute the plastic dropping bottle shell of fully hard matter; The diameter of movement at position, drop bottle funnel microporous membrane suitable for reading place is greater than the diameter of the above structure of drop bottle shell side wall vent openings, and it is up-thin-low-thick that integral body is
Shape.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is a structural representation proposed by the invention;
The specific embodiment
As shown in Figure 1, for proposed by the invention filtered liquid storage drop bottle enforcement structural representation from aerofluxus half full transfusion device, comprise drop bottle cover 1, drop bottle funnel 4, exhaust membrane 2, exhaust membrane gland 7 and microporous membrane 3, drop bottle cover 1 and drop bottle funnel 4 Butt sealings constitute the drop bottle shell, liquid flows to drop bottle funnel 4 from drop bottle cover 1, the sidewall design of drop bottle shell has vent openings 5, exhaust membrane 2 seals on the outside of the vent openings 5 that covers the drop bottle shell side wall, and microporous membrane 3 is installed in the orientation, downstream of drop bottle shell side wall vent openings 5; Microporous membrane 3 edges are sealed on the edge of correspondence suitable for reading of drop bottle funnel 4, and the position of microporous membrane 3 is positioned at the downstream direction of drop bottle shell side wall vent openings 5, and promptly the horizontal level of microporous membrane 3 is lower than the horizontal level of drop bottle shell side wall vent openings 5; Exhaust membrane 2 seals on the outside of the vent openings 5 that covers the drop bottle shell side wall, and the edge of exhaust membrane 2 is deflated mould lid 7 and overlays on the edge 6 that is sealed in drop bottle shell perforate 5; Drop bottle cover 1 and drop bottle funnel 4 Butt sealings constitute the plastic dropping bottle shell of fully hard matter; Drop bottle funnel 4 diameter suitable for reading is greater than drop bottle cover 1 upper part diameter.The design of drop bottle cover 1 upper end has dosing mouth 12 in addition, these dosing mouth 12 outer suit sealed gum caps 13, and drop bottle cover 1 inner tip inwardly is extruded with minim pipette 10, and the bottom of drop bottle funnel 4 is extruded with the street corner 11 that connects flexible pipe downwards.
During use, upstream liquid enters and arrives the exhausting window top edge in the drop bottle automatically, stops and keeping the state that drips of liquid level observation state and liquid automatically, after flow of liquid is intact, owing to microporous membrane tension force keep liquid can not leave film below, realize that liquid remains in the drop bottle.When feed liquor once more, afterwards liquid and last time the liquid automatic butt, the liquid plane of formation arrives the top of exhausting window once more.
The invention solves in the manually-operated waste time and energy and liquid is walked empty back to the danger that patient causes, realize filtration simultaneously to medicinal liquid.
