Description
Technical field
It the utility model is related to technical field of medical instruments, and in particular to a kind of transfusion of fast and accurately regulation drop speed
Device.
Background technology
One of Main Means of clinical treating disease are venous transfusions, it was reported that have 90%-95% inpatients to need vein
Infusion treatment.Infusion reaction refers to that factor causes patient reaction not because the transfusion speed of venous transfusion is improper etc. in fluid transport therapy
Good phenomenon.
Transfusion speed too fast the problem of causing is：（1）Circulating blood volume can be sharply increased, aggravate heart burden, cause the heart
Force failure and pulmonary edema, particularly children, old age and thoracic injury, the patient of heart failure are more easy to occur, and can cause fatal
Reaction；（2）Cause the blood concentration of medicine too high, if blood concentration exceedes safe range, there may be toxic action,
Particularly some therapeutic indexs are narrow, toxic action big medicine and traditional Chinese medicine.
The problem of transfusion speed causes slowly excessively be：Blood concentration is too low.For many medicines, blood concentration is that medicine rises
Whether imitate, whether produce the determinant of adverse reaction and toxic reaction.If blood concentration is less than due treatment concentration,
Due therapeutic effect is not reached then.
Therefore, treatment and prognosis of the appropriate and accurate transfusion speed for venous transfusion patient are particularly important, and 60 drops/point
This transfusion speed of clock can meet most of medical intravenous transfusion.The speed regulation of traditional infusion device relies primarily on nurse few drops
Number, it is inconvenient and time-consuming so to adjust, it is often more important that, it can not accurately control transfusion speed.
Utility model content
The purpose of this utility model is to be directed to deficiency of the prior art, and provides a kind of quickly and accurately by transfusion
Speed is adjusted to the transfusion device of 60 drops/minute.
To achieve the above object, the technical scheme that the utility model is taken is：The defeated of speed is dripped in a kind of fast and accurately regulation
Liquid device, the bottle cork needle being sequentially communicated, Murphy type burette, woven hose, liquid medicine filter and defeated are provided with by liquid medicine flow direction
Liquid syringe needle, is arranged with flow regulator on the woven hose, is carved with the center on the flow regulator along its length
One corresponding drop speed is the graduation mark of 60 drops/minute.
Wherein, the internal diameter of the woven hose is set to 2.7mm, and external diameter is set to 3.8mm, and point Drops coefficient is set to 20, the decoction
The aperture of filter is set to 5.0 μm, and the length of flow regulator is set to 4.7cm.
Wherein, the bottle cork needle is also arranged with bottle stopper puncture protective case.
Wherein, the transfusion device is set at least one of polyvinyl chloride, thermoplastic elastomer (TPE), polypropylene, polyethylene system
Into transfusion device.
The beneficial effects of the utility model：
The transfusion device of a kind of fast and accurately regulation drop speed of the present utility model, compared with prior art, by flow
The graduation mark that a drop speed is 60 drops/minute is designed at the center of adjuster, in use, stream will be slided at the center of speed governing roller
At the center for measuring adjuster, you can transfusion speed quickly and accurately is adjusted into 60 drops/minute.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the transfusion device of fast and accurately regulation drop speed of the utility model.
Fig. 2 is the structural representation of flow regulator in Fig. 1.
Fig. 3 is the diagrammatic cross-section of flow regulator in Fig. 1.
Reference：
1- bottle cork needles, 2- Murphy type burettes pin, 3- woven hoses, 4- liquid medicine filters, 5- infusion niidls, 6- flows are adjusted
Save device, 61-60 drops/minute track line, 62- speed governing roller, 63- sides cavity.
Embodiment
The utility model is further described with the following Examples.
A kind of embodiment of the transfusion device of fast and accurately regulation drop speed of the utility model, as shown in figure 1, pressing medicine
Liquid flow direction is connected with bottle cork needle 1, Murphy type burette pin 2, woven hose 3, liquid medicine filter 4 and infusion niidl 5 in turn,
The woven hose 3 is arranged with flow regulator 6, as shown in figure 3, the flow regulator 6 includes being used for the tune for extruding woven hose 3
Fast roller 62 and for being rolled for the speed governing roller 62 with the extruding different degrees of to woven hose 3 in the flow regulator 6
Side cavity 63, as shown in Fig. 2 being carved with a 60 drops/minute track at center on the flow regulator 6 along its length
Line 61.
Specifically, the flow regulator 6 that the present embodiment uses is market regular flow adjuster, by designing the transfusion
The internal diameter of pipe 3 is set to 2.7mm, external diameter is set to 3.8mm, point Drops coefficient is set to 20（That is 20 drops=1ml ± 0.1ml）, liquid medicine filter
4 aperture be set to 5.0 μm, the length of flow regulator 6 be set to these parameters of 4.7cm so that, when the center of speed governing roller 62
When place is at the center of flow regulator 6, extruding of the speed governing roller 62 to woven hose 3 just make it that the drop speed of transfusion device is 60
Drop/minute.
During use：As shown in Fig. 2 flow regulator 6 will slided to just at the center of the speed governing roller 62 of flow regulator 6
Middle place（That is at 60 drops/minute track line 61）, you can transfusion speed is quickly and accurately adjusted to 60 drops/minute.
In the present embodiment, the bottle cork needle 1 is also arranged with bottle stopper puncture protective case（Not shown in figure）.Due to bottle stopper
Puncture needle 1 belongs to sharp medical apparatus, by being arranged bottle stopper puncture protective case, can eliminate bottle cork needle 1 to medical personnel
With the potential injury of patient.
In the present embodiment, the transfusion device carried out sterilization treatment using oxirane.Transfusion device is safer, hygienic.
In the present embodiment, the transfusion device is at least one in polyvinyl chloride, thermoplastic elastomer (TPE), polypropylene, polyethylene
Transfusion device made of kind.Using above-mentioned non-toxic high molecular material, not only safety, and soft, it is easy to fetch and coils.It is preferred that
, transfusion device is transfusion device made of polyvinyl chloride.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
It is logical it will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent substitution, without departing from this
The spirit and scope of utility model technical scheme.
