Abstract

The utility model provides an automatic carry transfusion system of many bottles of liquid medicines in proper order in succession, it still installs a float valve controller additional in order to control the expert, the disconnected of liquid medicine between the drain needle of conventional transfusion system and flow controller. The transfusion device composed of the utility model can realize automatic and continuous transfusion in sequence for a plurality of bottles of liquid medicine (or different liquid medicines), thereby reducing labor intensity, having simple operation and low cost.

Description

Infusion apparatus adapted for automatic and continuous transporting multiple bottles of liquid medicine

This utility model relates to a kind of transfusion device, particularly a kind of transfusion device of carrying medicinal liquid to the patient.

At hospital ward during to the defeated many bottle liquid medicines of patient or during different medicinal liquids, the bottle liquid medicine of normally being totally lost whenever, the nurse just must come the patient by the side of, and the fluid-directing needle that will transfer in the medicinal liquid empty bottle inserts another bottle that medicinal liquid is housed, to proceed infusion process again.Though it is uncomplicated that this infusion model is operated, because the ward patient is many, particularly the just intact patient of operation all needs many bottles of transfusions every day and requires the different medicinal liquid of input in the different time again.And the nurse must all need repeat to dial pin, this operation of contact pin whenever being totally lost one bottle, therefore commute the labor intensity that has just increased the nurse between a plurality of patients, and look after the patient at nobody sometimes and fail in time to observe that the transfusion medicine bottle is whether intact the phenomenon that blood flows backwards along transfusion needle also can occur.

The purpose of this utility model provides a kind of transfusion device of importing many bottle liquid medicines (and can be many bottles of different medicinal liquids) automatically and continuously successively.

This utility model is to realize like this, it is mainly by medicine bottle, fluid-directing needle, conduit, reducer, the flow display tube, tube for transfusion and entry needle and float valve controller etc. are formed this transfusion device, the float valve controller is to be connected between fluid-directing needle and the reducer, this float valve controller is arranged in outer tube bore by outer tube and one, and on can be in outer tube, the float valve that moves is formed down, outer tube is by integrant body, tee T, t-joint three parts are formed, the tee T that flows into outer tube bore for the medicine bottle medicinal liquid is arranged at the top that is the body of hollow cylindrical, the tee T that communicates with tube cavity has a tubule insertion tube intracoelomic cavity, the t-joint that flow to reducer for the outer tube inner liquid medicine is arranged at the body bottom, and the one end opening is cylindric and has sealing and closes the opening of the float valve of cavity and be packaged with thin film.

Using this utility model is to utilize to enter the buoyancy that the interior medicinal liquid of outer tube produces float valve, make the float valve come-up withstand a tubule mouth of pipe of insertion outer tube bore upper end tee T to the thin film of its upper end, make the medicinal liquid on outer tube top can not enter in the outer tube, when first bottle of liquid storage drips when most, this moment is owing to the buoyancy to float valve exists hardly, at this moment, the medicinal liquid in the medicine bottle can flow into outer tube pipe following current and entering in patient's body again above outer tube.Therefore the continuous transfusion of many bottle liquid medicines is to control automatically by means of the float valve in each infusion pipeline, so simplified the transfusion formality, has alleviated the labor intensity of nurse's transfusion.

Below in conjunction with accompanying drawing this utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is many bottle liquid medicine transfusion sketch maps;

As seen from the figure: the float valve controller is made of outer tube 12 and float valve 11, consider to reduce cost and be convenient to float valve 11 is packed in the outer tube 12, outer tube 12 can be made up of tee T 15, body 21, t-joint 10, and body 21 is an elongated cylinder, and inner chamber hollow is to hold float valve 11 and medicinal liquid.Because of the tee T 15 that is loaded on outer tube 12 tops can be made straight tee, its tubule 14 should overlap in the threeway mouth of pipe that inserts outer tube 12 tops, and tubule 14 length of inserting in outer tube 12 mouths of pipe should guarantee that the thin film 13 of float valve 11 upper ends can seal this tubule 14 mouths of pipe reliably.One end diameter of t-joint 10 should be designed to be set in outer tube 12 inner chambers or outer tube 12 peripheries, float valve 11 is made up of with the thin film 13 that is installed in this cylinder opening end the cylinder of hollow and one end opening, thin film 13 can be bonding, but clip is on cylinder, float valve 11 outside diameter of cylinder should be less than outer tube 12 internal diameters 2 millimeter, and the draw ratio of cylinder is about 1.5-2.5.The cylinder that will be packaged with thin film 13 is packed in outer tube 12 inner chambers, and tee T 15, t-joint 10 are installed in the relevant position on the outer tube 12 respectively, and the mode of installing can adopt welding, mode such as bonding.

During use, the float valve of mode device shown in the map interlinking 1 controller 4, behind good this transfusion device of suspention reducer 5 cuts out, earlier fluid-directing needle 19 is inserted in the medicine bottle 20, the pipe cap 17 of will exitting is opened, this moment, medicine bottle 20 interior medicinal liquids flowed into the cavity of resorption of the outer tube 12 of float valve controllers 4 through tube for transfusion 18, outer tube 12 giving drugs into nose liquid levels rise gradually, air in the outer tube 12 is overflowed along bleeder pipe 16, along with outer tube 12 inner liquid medicines further increase, float valve 11 floats after thin film 13 parcel to float valve 11 blocks the lower nozzle of a tubule 14 of tee T 15 gradually, fluid-directing needle 2 is inserted in the medicine bottle 1, medicinal liquid in the medicine bottle 1 is along fluid-directing needle 2, catheter 3, tee T 15 packages venting pipe cap 17 after air is overflowed, because of the closing function that has a float valve 11 and a tubule 14 to form, medicinal liquid in the medicine bottle 1 can not flow in the outer tube 12, at this moment, open reducer 5, the medicinal liquid in the medicine bottle 20 is along conduit 18, the pipette 9 of t-joint 10, reducer 5, flow display tube 6, conduit 7, entry needle 8 flows out.After the medicinal liquid in the medicine bottle 20 flows to end, medicinal liquid in the outer tube 12 of float valve control device 4 can reduce gradually, and float valve 11 will descend gradually, thin film 13 is no longer blocked the mouth of pipe of a tubule 14, at this moment, the medicinal liquid in the medicine bottle 1 will be automatically along fluid-directing needle 2, conduit 3, tee T 15, and a tubule 14 flows in the outer tube 12, and flow in the entry needle 8, thereby finish the process of automatic transport medicinal liquid downwards along the space between float valve 11 and outer tube 12 inwalls.When importing 3 bottles medicinal liquid for need, can connect by Fig. 2 mode and promptly on the basis of Fig. 1, add a transfusion device of the present invention again, and the pipette 9 usefulness conduits on the three way cock of the bleeder pipe 16 on the float valve controller 4 on first transfusion device and the float valve controller bottom of second transfusion device are communicated with realize three bottles of automatic infusions successively.The automatic infusion successively of medicinal liquid is then analogized by this more than three bottles.
