Abstract
The utility model discloses an infusion apparatus comprising a puncture outfit, a liquid-adding device, a regulator, a filter and a puncture needle which are sequentially connected with one another through a hose. A dropper is arrange at the top of the liquid-adding pipe, a rising-stopper ridge is arranged on a cross section of the liquid-adding pipe, a floating plug with the bottom inlaid with a latex ring cap is arranged in a space between the rising-stopper ridge and the bottom of the liquid-adding pipe, one side of the latex ring cap is provided with a latex film ring, a liquid outlet pipe is arranged at the bottom of the liquid-adding pipe, and a latex film is opposite to the outlet pipe. When medical liquid is completed in actual use, the floating plug in the liquid-adding pipe can automatically seal the outlet pipe at the bottom of the liquid-adding pipe to prevent air from entering an infusion pipe under the outlet pipe, so that the air is prevented from entering a human body, and safe infusion is realized.
Description
Technical field
This utility model relates to medicine and hygiene fields, the transfusion device that uses when more specifically relating to a kind of the transfusion.
Background technology
At medicine and hygiene fields, transfusion is the conventional means in the medical treatment at present, is extensive use of disposable infusion set the patient is carried out venous transfusion, have the vein medicine easy to operate, improve curative effect, disposable use prevents the positive role of cross infection.And the used transfusion device of infusing adopts packed form or bottled form mostly, transfusion set does not possess self closing device, therefore in transfusion, medical personnel will nurse the decline situation of the medicinal liquid of transfusion device inside at any time, in order to avoid because of the medicinal liquid deficiency, in time do not change dressings or stop injection and cause accident.Use transfusion set in addition, inconvenient two kinds of medicinal liquids are infused jointly or are dripped medicinal liquid midway.
The utility model content
This utility model proposes a kind of safe transfusion device that makes things convenient for liquid feeding at the deficiencies in the prior art.
According to an aspect of the present utility model, a kind of transfusion device is provided, comprise the perforator, liquid-feeding tube, actuator, filter and the puncture needle that connect successively by infusion tube, the top of liquid-feeding tube is provided with dropper, and the cross section of liquid-feeding tube is provided with and only rises bank, only rise bank and liquid-feeding tube the bottom the space in be provided with floating plug, the bottom of floating plug is inlaid with latex ring medicated cap, latex ring medicated cap is for simultaneously being provided with the annulus of latex thin film, and the bottom of liquid-feeding tube is provided with drain pipe, and the latex thin film is relative with drain pipe.
Medicinal liquid enters in the liquid-feeding tube by perforator.Only rising the bank middle part is an annulus, and annulus is horizontally disposed with, and annulus is connected with the ring wall of liquid-feeding tube by three plastics barred bodies, and it is fixing within the specific limits with floating plug only to rise bank, and the position is too high with the rising of medicinal liquid liquid level to prevent floating plug; Floating plug is gear-like, and one side is convex surface, and one side is concave surface; Be provided with latex ring medicated cap in the concave surface of floating plug, latex ring medicated cap is for simultaneously being provided with the latex annulus of latex thin film, and the whole plug of latex ring medicated cap is in the concave surface of floating plug, and the latex thin film of latex ring medicated cap is over against the liquid outlet of liquid-feeding tube bottom.In infusion process, because medicinal liquid is to the buoyancy of floating plug, floating plug can not touch liquid outlet, and when medicinal liquid will be failed to the greatest extent, floating plug was not subjected to the buoyancy of medicinal liquid, latex ring medicated cap in the floating plug contacts with the liquid outlet of liquid-feeding tube, the latex thin film is close to liquid outlet, thereby the sealing liquid outlet makes air not enter into tube for transfusion under the liquid outlet, thereby prevent the air admission human body, realize safe infusion.Actuator is used for regulating the speed that medicinal liquid is carried.Filter filters medicinal liquid, by puncture needle the patient is carried out intravenous injection at last.
In some embodiments, the oblique upper of liquid-feeding tube is provided with filling opening.The convenient two kinds of medicinal liquids of filling opening are infused simultaneously, perhaps increase the transfusion medicinal liquid midway.
In some embodiments, perforator is provided with steam vent, and the upper end of steam vent is provided with baffle plate.It is bigger that baffle plate arranges, and when medical personnel infuse in reality, operates more conveniently, can easier perforator be injected in the infusion bottle.
In some embodiments, floating plug is gear-like.The floating plug of gear-like makes things convenient for passing through of medicinal liquid.
In some embodiments, only rising the bank middle part is an annulus, and annulus is horizontally disposed with, and annulus is connected with the ring wall of liquid-feeding tube by three plastics barred bodies.
In some embodiments, the external diameter of floating plug is less than the internal diameter than liquid-feeding tube.Make floating plug can be in liquid-feeding tube free floating.

The specific embodiment
Shown in Fig. 1-5, a kind of transfusion device comprises the perforator 1, liquid-feeding tube 2, actuator 3, filter 4 and the puncture needle 5 that connect successively by infusion tube 6.
The oblique upper of liquid-feeding tube 2 is provided with filling opening 21, the top of liquid-feeding tube 2 is provided with dropper 22, and the cross section of liquid-feeding tube 2 is provided with and only rises bank 26, only rises in the space of bank 26 and liquid-feeding tube 2 bottoms and is placed with floating plug 23, the bottom of floating plug 23 is inlaid with latex ring medicated cap 24, and the bottom of liquid-feeding tube 2 is provided with drain pipe 25.Floating plug 23 is gear-like.The floating plug 23 of gear-like makes things convenient for passing through of medicinal liquid.The external diameter of floating plug 23 is less than the internal diameter of liquid-feeding tube 2, thus make floating plug 23 can be in liquid-feeding tube 2 free floating.Filling opening 21 convenient two kinds of medicinal liquids of liquid-feeding tube 2 oblique uppers are infused simultaneously, perhaps increase the transfusion medicinal liquid midway.Only rising bank 26 middle parts is an annulus, and annulus is horizontally disposed with, and annulus is connected with the ring wall of liquid-feeding tube 2 by three plastics barred bodies.Only rise bank 26 floating plug 23 is fixed within the specific limits, the position is too high with the rising of medicinal liquid liquid level to prevent floating plug 23.Floating plug 23 is gear-like, and one side is convex surface, and one side is concave surface.Be provided with latex ring medicated cap 24 in the concave surface of floating plug 23.Latex ring medicated cap 24 is provided with the annulus of latex thin film 241 for one side.Latex ring medicated cap 24 whole plugs are in the concave surface of floating plug 23, and the latex thin film 241 of latex ring medicated cap 24 is over against the drain pipe 25 of liquid-feeding tube 2 bottoms.
In infusion process, owing to the buoyancy of medicinal liquid to floating plug 23, floating plug 23 can not touch drain pipe 25; When medicinal liquid will be failed to the greatest extent, floating plug 23 is not subjected to the buoyancy of medicinal liquid, latex ring medicated cap 24 in the floating plug 23 contacts with the drain pipe 25 of liquid-feeding tube 2, latex thin film 241 is close to drain pipe 25, thereby sealing drain pipe 25, make air not enter into infusion tube 6 under the drain pipe 25, thereby prevent the air admission human body, realize safe infusion.Actuator 3 is used for regulating the speed that medicinal liquid is carried.4 pairs of medicinal liquids of filter filter, and carry out intravenous injection by 5 couples of patients of puncture needle at last.
