Beneficial effect
The invention provides a kind of single intravenous infusion volume dropping funnel, it utilizes the former of stethoscope and microphone
Reason, in infusion process, by voice collection device, dripping of accurate acquisition medicinal liquid drop is fast, connects external system
Transfusion speed is precisely controlled by system, to realize the precision transfusion on the basis of gravity infusion.Compared to other essence
Close infusion set, the present invention has simple in construction, and flow velocity monitoring effect is good, and volume small occupied space is few, can make
The property made is strong, the features such as technology extending space is big；Clinical practice can effectively control transfusion speed, automatically cut
Only, not only improve nursing quality, energy-conserving and environment-protective, also have deeper technology wider space, make transfusion real time imaging
Monitoring is possibly realized.
Detailed description of the invention
Conventional disposable intravenous infusion set generally includes: wear a bottle pin, upper tubing, dropping funnel, lower tube for transfusion,
Flow control valve, air filtration bubble, capillary soft tube, puncture needle, in infusion process, the Peak Flow Rate of medicinal liquid is subject to
Medicinal liquid suspension height, wear a bottle pin hole footpath, upper and lower tube for transfusion caliber, capillary soft tube caliber, the shadow in puncture needle aperture
Ring, and be adjusted less than in the range of Peak Flow Rate under the regulation effect of flow control valve, the spy of dropping funnel
Different design makes medicinal liquid form drop when entering dropping funnel from upper tubing, it is thus possible to judge defeated according to the speed of dripping of drop
Liquid speed, the lower semisection at dropping funnel accumulates the medicinal liquid of certain altitude simultaneously, easily facilitates the observation that medicinal liquid drips speed,
Venous transfusion volume dropping funnel, according to the feature of conventional intravenous transfusion device, uses stethoscopic principle to add in dropping funnel
Volume device, makes drips in the drum surface of volume device, judges flow velocity by drop drips the analysis of speed,
Use process is essentially identical with conventional infusion device, after opening the transfusion device equipped with venous transfusion volume dropping funnel, by quiet
Arteries and veins transfusion volume dropping funnel is inverted, and just puts when containing the medicinal liquid less than dropping funnel hypomere or sound conduit height in dropping funnel
Dropping funnel, outer welding system is connected into sound leadout hole or by the dropping funnel outer catheter part of the sound conduit of dropping funnel hypomere and
Drain pipe road is affixed in outer welding system, after setting required transfusion speed on welding system outside, and medicinal liquid
Enter dropping funnel feed tube through upper tubing, at the dropping funnel feed liquor mouth of pipe, form drop, fall and be positioned at dropping funnel center
On the tympanum of the volume device of centre, the tympanum formed between tympanum shell and the tympanum shock tympanum drum surface to drop
The sound formed produces expansion, gathers and conduction, is conducted by sound wave by the sound conduit being connected with tympanum
To outer welding system, the sound wave of drop can be added up the frequency drawing drop by outer welding system, due to dropping funnel feed liquor
The caliber of the mouth of pipe is fixed, and the volume size of drop is also certain, so by the frequency to the drop sound wave gathered
Analyze and i.e. can determine whether medicinal liquid flow velocity in transfusion device, and use outer welding system by adjusting tube for transfusion caliber, control
Drop frequency processed reaches required transfusion speed, and in infusion process, the image that outer welding system can be used to configure is received
Collection and transmission system real-time infusion monitoring situation, it is achieved the high-end medical treatment and nursing such as remote adjustment transfusion speed, transfusion
At the end of, the tympanum in dropping funnel exceedes adjacent two drops physic liquors setting transfusion speed corresponding and fails to gather interval time
To acoustic information, outer welding system just according to circumstances can realize transfusion and cuts by the completely liquid medicine flow in stopping infusion apparatus
Only, preventing transfusion from terminating transfusion device and can not end the complication after punctures such as the blood back that causes in time.If continuing transfusion,
Only need to change medicinal liquid bottle and outside welding system release cut-off or set new infusion flow rate and can enter continuation transfusion
State.
Venous transfusion volume dropping funnel and the outer welding system one assembling of separate case application, constitute venous transfusion flow speed control
Device processed；After it is connected with upper tubing and lower tube for transfusion, constitute disposable accurate intravenous transfusion device.Disposably
Transfusion speed can be realized on the basis of gravity infusion pre-under the support of accurate intravenous transfusion device welding system outside
First set, it is also possible to the long-range real-time monitoring of transfusion speed during real limit venous transfusion and real-time pictures monitoring,
Realization for high-end transfusion nursing is laid a good foundation.
In process of production, the structural member in this case uses conventional manufacturing techniques to produce, and can manufacture
Property strong, production cost is low；Using multimode injection moulding to manufacture, production efficiency is high；Tympanum can use relatively soft, bullet
Property and the stronger latex material of toughness make, both can ensure that the sealing of tympanum was to strengthen the expansion to drop sound
And collecting effect, meanwhile, increase overall appearance effect.
Venous transfusion volume dropping funnel provided by the present invention, rational in infrastructure, deft design, energy-saving safe, property
Can be reliable and stable；Its voice collection device in the liquid outlet one end within dropping funnel, does not affect drop in dropping funnel
Formed and observing effect, do not increase the volume of dropping funnel and affect outward appearance, with the biography of disposable general infusion set dropping funnel
System style is similar or close；Dropping funnel liquid outlet can directly connect with lower tube for transfusion, does not affect the stream of medicinal liquid
Dynamic effect, dropping funnel, more than or equal to defined flow standard in GB, is fixed by its amount of flow by sound conduit
Design there is initiative, provide technical support and basis for the most high-end long-range monitoring infusion.
Being equipped with the disposable accurate intravenous transfusion device of the present invention, the work not changing medical personnel is practised
Used, its operation sequence is identical with conventional disposable intravenous infusion set, is easy to learn and use；Compared to other flow speed control
Device, has simple in construction, energy-saving safe, the features such as follow-up extending space is big, and manufacturability is strong；Clinic should
Medical personnel's labor intensity can be effectively reduced in, save the substantial amounts of people taken for regulation and control transfusion speed
Power resource, makes the most convenient specification of infusion management, nurses the most intimate.
