The specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, infusion bottle alarm for infusion 1, hang on infusion bottle 2 and use, and mainly comprises snap ring 11, fuselage 12; Fuselage 12 is provided with air inlet and spigot joint 13.
Be provided with air flue in fuselage, an end of air flue communicates with spigot joint 13, and the other end communicates with air inlet.Be provided with pressure check valve in air flue, pressure check valve and spigot joint between air flue on be provided with perforate, be provided with pressure transducer in perforate.Also be provided with alarm device and control device in fuselage.The signal of pressure transducer passes to control device by holding wire, and the pressure signal that control device transmits pressure transducer is analyzed judgement, determines whether to open alarm device and reports to the police.
Air inlet pipe 3 one ends are socketed on spigot joint 13, and the other end is provided with air inlet needle, and the air inlet pinprick advances in bottle neck.Pressure transducer seals perforate, while in air flue, forming negative pressure, pressure transducer just can detect identical negative pressure signal, then the negative pressure signal detected is passed to control device, the pressure signal that control device transmits pressure transducer is analyzed judgement, determines whether to open alarm device and reports to the police.
When the pressure of negative pressure is less than the setting value of pressure check valve, pressure check valve is in closed condition, and when the pressure of negative pressure is greater than the setting value of pressure check valve, pressure check valve just can be opened air inlet, and extraneous air could flow into.
When medicinal liquid flows away while causing the negative pressure that produces in infusion bottle enough large, the air of inhaling in moving air inlet pipe enters supplementary, thereby make in air inlet pipe and air flue also to produce negative pressure, this negative pressure is greater than the setting value of pressure check valve, and pressure check valve is opened, extraneous air flows into air flue and air inlet pipe, add in infusion bottle, the inside and outside pressure of infusion bottle is averaged out, air stops entering infusion bottle, negative pressure in air inlet pipe and air flue reduces, and pressure check valve is closed.
Before use, the liquid pinprick that draws that is located at upper dropper end is entered to bottle cap, open by-pass cock, medicinal liquid is affected by gravity by drawing the liquid pin and enters upper dropper, then enter and drip capsule, and then dropper under flowing into, Bas Discharged in managing under the promotion of medicinal liquid, after the transfusion needle of medicinal liquid dropper end from being positioned at oozes two or three, then be inserted into transfusion needle on patient's remaining needle, set up the path of transfusion, then regulate the speed of transfusion by by-pass cock.
During normal infusion, due to bottle inner liquid medicine amount abundance, liquid level is not less than and draws the liquid pin, and return-air is intermittent.Only have when liquid level drops to a certain degree, just can produce the negative pressure of enough air amounts in bottle, only have negative pressure to acquire a certain degree, just can be air-breathing, when air enters infusion bottle, the pressure that medicinal liquid is produced substantially equates with atmospheric pressure with the pressure sum of γ-ray emission in bottle, stops suction, at the uniform velocity lower of medicinal liquid input human body, until the negative pressure produced in bottle again reach air-breathing degree just can be again air-breathing.
Owing to by by-pass cock, regulating the speed of transfusion, medicinal liquid in infusion bottle is at the uniform velocity dirty, therefore, producing enough negative pressure in bottle is also stable by the defeated frequency of crossing in bottle of extraneous air intake, at this moment, open the switch activated control system work be located on fuselage, control system is at first with within 1-2 minute, recording the pressure signal that pressure transducer transmits, the information such as signal intensity when air inlet frequency when control system is recorded normal infusion and air inlet, and by these information as reference value, then, the pressure signal that control system is constantly sent pressure transducer compares with the reference value of recording, determining whether to open alarm device reports to the police.
When liquid level during lower than the air inlet syringe needle, due to the separation that there is no liquid, therefore, will produce continuous negative pressure in air flue, the signal that pressure transducer returns to control system is exactly continuous negative pressure signal, and signal frequency also can change, when control system detects continuous negative pressure signal and frequency higher than reference value, control system is opened alarm device and is reported to the police, and reminds sufferer and nurse's transfusion to be near completion.
The signal intensity and the reference value that return to control system when control system monitor force sensor are consistent, but the air inlet frequency opens alarm device and report to the police lower than half of reference value, remind sufferer and nurse, and liquid-transport pipe-line causes transfusion speed to slow down because stop up.
As shown in Figure 3, infusion bottle alarm for infusion 1 hangs over infusion bottle 2 belows by snap ring 11, the annular that snap ring 11 is a side opening, and snap ring is stuck on the bottleneck of infusion bottle; Lower limb at snap ring is provided with the contiguous block 14 to downward-extension, and the lower limb of contiguous block is connected with the roof of fuselage 12, makes fuselage hang over the snap ring below.
When snap ring is stuck on bottleneck, fuselage is positioned at the bottle neck below.
Be provided with top-down groove 15 on the end face of upper tubing 5 at fuselage, groove is semicircle, and its diameter is greater than the diameter of upper tubing; During use, upper tubing is positioned at the transfusion tube seat.
