Abstract

The utility model is a disposable transfusion system which can identify the using of transfusion device. The utility model comprises a hard plastic plug, an upper soft plastic pipe, a soft plastic liquid-dropping bottle, a lower soft plastic pipe and a connector. These components are orderly connected in heat. The connector and the small soft plastic pipe are closely connected, and the small soft plastic pipe is connected with the needle. A hard plastic ball is arranged in the liquid-dropping bottle, and a layer of plastic identification film is provided between the upper and lower part of the soft plastic liquid-dropping bottle. The location of the hard plastic ball and the identification of the damaged film can be used to determine whether the transfusion device has been used or not.

Description

Disposable transfusion device

Technical field

This utility model is that a kind of disposable infusion device, particularly people can identify is used transfusion device.

Background technology

As everyone knows, present disposable transfusion device be by mould plug, air inlet soft plastic pipe, top soft plastic pipe firmly, the soft drop bottle, bottom soft plastic pipe, gauge tap, joint, thin soft plastic pipe, syringe needle moulded combines.During use, will mould plug firmly and insert in the medicine bottle, and make medicinal liquid enter soft moulding in the drop bottle in right amount, and then be full of whole bottom soft plastic pipe, thin soft plastic pipe, syringe needle, pay close attention to gauge tap this moment, syringe needle penetrated in the vein blood vessel of human body, opens gauge tap and can infuse.Though be printed on disposable transfusion device on these general transfusion device packings, but some illegal unscrupulous merchant washes the exhausted disposable transfusion device that buys through simple, packing is sold away again once more, such transfusion device people can't see and whether used, if use such transfusion device transfusion probably to bring very big harm to patient.

Summary of the invention

In order to overcome that existing disposable transfusion device people can not find out intuitively is the deficiency of exhausted transfusion device, a kind of disposable transfusion device that this utility model provides, it not only can be infused, and can find out it easily and whether use, and transfusion is more than two bottles or two bottles the time, be totally lost after one bottle, can stop automatically, use another bottle liquid medicine instead and save worry very much again conveniently.

The technical scheme that its technical problem that solves this utility model adopts is: mould air inlet and air inlet soft plastic pipe on the plug firmly, the air filter heat seal connects, mould the infusion hole on the plug firmly, the top soft plastic pipe, the soft drop bottle of moulding, the bottom soft plastic pipe, joint, thin soft plastic pipe, syringe needle is connected successively, gauge tap is arranged on the soft plastic pipe of bottom, the key of this new design is an average density is set in the drop bottle moulds bead firmly less than medicinal liquid density soft moulding, and at soft top of moulding drop bottle and lower part the intermediate heat thin and crisp plastic identification film of one deck that closes, and make and mould bead firmly on the identification film.Like this, people see and mould bead firmly on the identification film, and the identification film is excellent, illustrates that this transfusion device did not use; When people use, pinch soft top of moulding drop bottle with hands, bead is moulded in extruding firmly, make and mould bead bursting identification film firmly and fall into soft bottom of moulding drop bottle, use according to the using method of general transfusion device again to get final product, reflect thus, mould bead firmly below the identification film of breakage the time when people see, illustrate that this transfusion device used, whether use so people can find out transfusion device easily.When transfusion is carried out, owing to mould the density of the average density of bead firmly less than medicinal liquid, bead is in floating state, after a bottle liquid medicine was totally lost, the soft liquid level of moulding in the drop bottle descended, when liquid level drops to a certain degree, mould buoyancy that bead is subjected to firmly less than its gravity that is subjected to, mould firmly and ask for a short time and will fall behind soft bottom of moulding drop bottle, cover the transfusion outlet, transfusion will stop automatically.When changing another bottle liquid medicine, only need to insert in the new medicinal liquid bottle moulding plug firmly, reuse hands extruding is soft mould drop bottle in, top discharges portion of air, after loosing one's grip, because the soft air pressure of moulding in the drop bottle reduces, medicinal liquid in the medicine bottle is under the effect of self pressure and atmospheric pressure, enter soft moulding in the drop bottle, to equal its gravity that is subjected to floating because of the buoyancy that is subjected to again to mould bead firmly, therefore transfusion will go on again, the care-giver just waits for without the undue concentration attention and changing dressings like this, thereby has also reached the purpose that the care-giver is saved worry.

The beneficial effects of the utility model are that it can also allow people find out for people infuse easily, it has not used, can also alleviate the psychological burden of care-giver when changing dressings, duroplasts bead, plastic identification film during this is novel are easy to process, simple in structure.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Be vertical section of the present utility model structural map as shown in Figure 1; Fig. 2 is the soft profilograph of moulding drop bottle; Fig. 3 is the soft top profilograph of moulding drop bottle; Fig. 4 is the soft lower part profilograph of moulding drop bottle; Fig. 5 is the plan view of plastic identification film.

Among the figure 1, mould plug firmly, 2, air inlet, 3, infusion hole, 4, air inlet soft plastic pipe, 5, air filter, 6, the top soft plastic pipe, 7, mould bead firmly, 8, the plastic identification film, 9, the soft drop bottle (the soft soft lower part of moulding drop bottle of top, 9B of moulding drop bottle of 9A) of moulding, 10, bottom soft plastic pipe, 11, gauge tap, 12, joint, 13, filter membrane, 14, thin soft plastic pipe, 15, syringe needle.

The specific embodiment

Among the embodiment as shown in the figure, the lower end, air inlet soft plastic pipe (4), air filter (5) of moulding the air inlet (2) in the plug (1) firmly heat seal successively links to each other, mould firmly the lower end, top soft plastic pipe (6) of the infusion hole (3) in the plug (1), soft upper end of moulding drop bottle (9), bottom soft plastic pipe (10) successively heat seal link to each other, bottom soft plastic pipe (10) passes gauge tap (11) and links to each other with the upper end heat seal of joint (12), the lower end of joint (12) links to each other with thin soft plastic pipe (14) extruding, and the lower end of thin soft plastic pipe (14) links to each other with syringe needle (15) heat seal; Filter membrane (13) will cover the inside of whole joint (12) completely, mainly be that the soft diameter of moulding in the drop bottle (9) of moulding bead (7) firmly is soft 1/2～2/3 of the drop bottle diameter of moulding, can be hollow, but its average density must be less than the density of medicinal liquid, certain rigidity is arranged, can not be out of shape when pushing it, want energy bursting plastic identification film (8), heat seal is soft when moulding the top (9A) of drop bottle (9) and lower part (9B), heat seal will thoroughly separate them at their intermediary plastic identification films (8), and its diameter is identical with the soft diameter of moulding drop bottle (9), and will approach and crisp, when bead (7) is moulded in extruding firmly, be easy to plastic identification film (8) bursting, and drop to soft bottom of moulding drop bottle (9), soft bottom of moulding drop bottle (9) should be funnel-form, after moulding bead (7) firmly and falling down, downward infusion port can be covered completely.
