Abstract

The utility model relates to a dropping structure which is mainly composed of a dropping bag, a tube body and an injection needle, wherein, the tube body comprises a switching part which enables the liquid medicine which flows into the tube body from the dropping bag flows into the successive tube body via the switching part; the dropping structure has the improvement that a floating body is arranged in the switching part, a detector which can induct the height change of the floating body is arranged outside the switching part, thus the detector can detect whether the liquid medicine which flows into the switching part is too much or too little, and sufferers or medical staffs are warned.

Description

Drip structure

Technical field

This utility model relates to a kind of drip structure.

Background technology

In medical treatment, for helping sufferer to regain one's strength fast, rely on injection as drops such as glucose and other nutritional solutions mostly, or make long-time, medicine is injected in the body slowly, therefore also rely on medicinal liquid to be mixed with Glucose Liquid or normal saline solution, slowly injecting blood vessel in the drop mode enters in the body, so often can see in medical institutes that drip bag is suspended on the infusion stand and inject, or for ease of the sufferer action, when going to toilet or taking a walk, be to have portable structural design, make sufferer can promote the infusion stand action voluntarily, to keep the medical act of injection.

Yet generally when injecting, because inject time is very long, after the injecting liquid drug in the drip bag finished, patient or medical personnel were still unconscious, so this utility model designer research and development improvement that constantly progresses greatly, and developed a drop structure eventually.

Summary of the invention

Main purpose of the present utility model can be detected injection during drop, the drip structure whether output of medicinal liquid in drip bag changes immediately providing a kind of.

Another purpose of the present utility model provide that a kind of cost is low, simple in structure, also drip structure very easily in the use.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of drip structure is made up of drip bag, body and entry needle, and wherein said body is to include a switching part, makes after the intravital medicinal liquid of drip bag inflow pipe is via described switching part, flows into the body that continues again; It is characterized in that:

Be provided with a buoyancy aid in the described switching part, and the switching part outside is provided with the detector that can respond to this buoyancy aid height change.

Compared with prior art, the beneficial effect that the utlity model has is: when the amount of liquid medicine in the inflow switching part is too much or very few, can detect by described detector, to remind patient or medical personnel.

The specific embodiment

See also the 1st, 2 figure, graphic content is an embodiment of this utility model drip structure 1, mainly formed with entry needle 4 by drip bag 2, body 3, wherein said body 3 is to include a switching part 30, after making medicinal liquid in drip bag 2 flows into bodys 3 via described switching part 30, the body 3 that continues of inflow again.

Be provided with a buoyancy aid 31 in the described switching part 30, described switching part 30 is to contract to internal diameter, makes described switching part 30 be a L type, in buoyancy aid 31 then can be limited in.Switching part 30 outsides are provided with the detector 32 that can respond to these buoyancy aid 31 height change, but wherein said detector 32 is the light beam receiving elements 322 that comprise a beam emissions part 321 and receiving beam emission part 321 light beam that sends, and the top of buoyancy aid 31 is to be placed between beam emissions part 321 and the light beam receiving element 322, and the top of described buoyancy aid 31 is that the material that can block described light beam is made.Described detector 32 is provided with a folder and ends device 33, described folder ends device 33 and is arranged on the body 3 and can be controlled by described detector 32, described again detector 32 is provided with an attention device 34 that is used for reminding patient or medical personnel, and described attention device 34 is an audio unit or light-emitting device.

During enforcement, please consult shown in the 1st～3 figure, when carrying out fluid infusion, at first the healthcare givers after earlier entry needle 4 being inserted patient's injection part 5, temporarily is fixed on entry needle 4 on the injection part 5 with an adhesive tape 6 more again.When injecting, in the drip bag 2 medicinal liquid can splash in switching part 30 according to a speed of setting, flow out with fixed speed by described switching part 30 again, buoyancy aid 31 in the therefore described switching part 30, because of the relation that persists medicinal liquid in the switching part 30 can be floated, and described buoyancy aid 31 floats its top, back and just can be between beam emissions part 321 and the light beam receiving element 322, and can cover 321 emitted light beams of beam emissions part, and light beam receiving element 322 can't be received.

Therefore, as shown in Figure 3A, when rapid change that drip bag 2 medicinal liquids splash into (too fast), make that medicinal liquids accumulation in the switching part 30 is excessive and make buoyancy aid 31 upwards float, or shown in Fig. 3 B, when the speed that splashes into when drip bag 2 medicinal liquids is crossed slowly or is dripped off soon, make medicinal liquids in the switching part 30 reduce and make buoyancy aid 31 to sinking, this moment, described buoyancy aid 31 tops promptly can't be interdicted 321 emitted light beams of beam emissions part again, make light beam receiving element 322 be received described beam signal, and then interlock attention device 34 is to remind patient or medical personnel, also but the interlock folder ends device 33 clamping bodys 3 simultaneously, after treating that medical personnel handle, the pine oil folder ends device 33 and continues or stop injection according to circumstances.

More than explanation is just illustrative for this utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
