The specific embodiment
As depicted in figs. 1 and 2, a kind of isolator for infusion bottle in infusion process, hangs up reminiscences 1 on infusion bottle 3, and an isolator 2 is set between reminiscences and infusion bottle.
As shown in Figure 3, described reminiscences 1 mainly comprises snap ring 11, fuselage 12; It is spigot joint 13 that fuselage 12 is provided with, and spigot joint one end is connected with isolator, and the other end is provided with pressure transducer, and pressure transducer is connected to control device by holding wire; In fuselage, be also provided with alarm device and 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.
As shown in Figure 4, Figure 5 and Figure 6, described isolator 2 comprises signal pipe 21, lower spigot joint 22 and air bag 23; Upper signal pipe and lower spigot joint socket form a cavity, and air bag is positioned at cavity; Air bag is the hollow utricule of an end opening, and the edge of opening is connected with the inwall of cavity, and cavity is divided into two independently spaces, and one is signal space, and one is airflow space, and the opening of air bag is towards lower spigot joint; Upper signal pipe 21 is provided with interface and spigot joint 13 sockets.
Be provided with outwards outstanding suction nozzle and outlet nozzle being positioned on airflow space lower spigot joint, one end of outlet nozzle and air inlet pipe 4 is socketed, and suction nozzle communicates with outside air, is provided with pressure check valve in suction nozzle.
The other end of air inlet pipe is provided with air inlet needle, in air inlet pinprick bottle inlet mouth; Air bag can be under the effect of negative pressure to the direction contraction distortion of suction nozzle; The distortion of air bag causes signal space to expand, thereby produces negative pressure, and negative pressure signal passes to pressure transducer by spigot joint 13; When the pressure of the negative pressure in airflow space is less than the unlatching value of pressure check valve, pressure check valve is in closed condition, and when the pressure of negative pressure is greater than the unlatching value of pressure check valve, pressure check valve just can be opened air inlet.
When medicinal liquid flows away while causing the negative pressure that produces in infusion bottle enough large, inhale air in moving air inlet pipe and airflow space enter supplementary, thereby make air inlet pipe and airflow space also produce negative pressure, air bag is to the direction contraction distortion of suction nozzle; Negative pressure in airflow space continues to increase, until the unlatching value that is greater than pressure check valve in airflow space, pressure check valve is opened, extraneous air flows into airflow space and air inlet pipe, adds in infusion bottle, and the inside and outside pressure of infusion bottle is averaged out, air stops entering infusion bottle, negative pressure in air inlet pipe and airflow space reduces, and air bag is replied original shape, and pressure check valve is closed.
Described pressure check valve mainly comprises valve ball 24, spring 25, snap ring 26; On inwall at suction nozzle near airflow space, be provided with bayonet socket, during installation, valve ball 24 filled in to suction nozzle from airflow space, then be pressed into spring 25, finally snap ring 26 is snapped on the bayonet socket of suction nozzle inwall.
When airflow space is during in negative pressure state, negative pressure can overcome the prestressing force of spring to the suction of valve ball, valve ball direction to airflow space in suction nozzle moves, and extraneous air enters suction nozzle from the gap between valve ball and suction nozzle inwall, then enters airflow space.When the negative pressure of airflow space reduces, when negative pressure can not overcome the prestressing force of spring to the suction of valve ball, spring pushes back original position by valve ball, blocks the import of suction nozzle, and extraneous air can not be entered.Therefore, the suction nozzle diameter of bore between valve ball and the inlet end of suction nozzle is less than the diameter of valve ball.
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 liquid pin and enters upper dropper, then enter and drip capsule, and then dropper under flowing into, under the promotion of medicinal liquid, by the Bas Discharged in pipe, when the transfusion needle of medicinal liquid dropper end from being positioned at oozes after two or three, then transfusion needle is inserted on patient's remaining needle, set up the path of transfusion, then by by-pass cock, regulate the speed of transfusion.
Owing to regulating the speed of transfusion by by-pass cock, medicinal liquid in infusion bottle is at the uniform velocity dirty, therefore, in bottle, producing enough negative pressure is also stable by the frequency in extraneous air intake infusion bottle, at this moment, open the switch activated control device work being located on fuselage, control device is 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 device is recorded normal infusion and air inlet, and by these information as reference value, then, the pressure signal that control device is constantly sent pressure transducer compares with the reference value of recording, determining whether to open alarm device reports to the police.
During normal infusion, because bottle inner liquid medicine amount is sufficient, liquid level is not less than and draws liquid pin, and return-air is intermittent.Only have when liquid level drops to a certain degree, in bottle, just can produce the negative pressure of enough air amounts, only have negative pressure to acquire a certain degree, just can be air-breathing, when air enters infusion bottle, the pressure that medicinal liquid produces is equated with atmospheric pressure substantially with the pressure sum of γ-ray emission in bottle, stop suction, at the uniform velocity lower of medicinal liquid input human body, until the negative pressure producing in bottle again reach air-breathing degree just can be again air-breathing.
When liquid level is during lower than air inlet syringe needle, owing to there is no the separation of liquid, air communication in airflow space, air inlet pipe and infusion bottle, therefore, when medicinal liquid continues when dirty, can make the air in infusion bottle produce negative pressure, in air inlet pipe and airflow space, will produce continuous negative pressure, when negative pressure is greater than the unlatching value of pressure check valve, pressure check valve is opened, extraneous air enters airflow space and then enters infusion bottle, makes medicinal liquid can continue lower.
When airflow space produces negative pressure, negative pressure makes air bag to the Direction distortion of suction nozzle, make signal space produce negative pressure, the signal that pressure transducer returns to control device is exactly continuous negative pressure signal, signal frequency also can change, when control device detects continuous negative pressure signal and frequency higher than reference value, control device is opened alarm device and is reported to the police, and reminds sufferer and nurse's transfusion to be near completion.
When control device, to monitor the signal intensity that pressure transducer returns consistent with reference value, but air inlet frequency is lower than half of reference value, opens alarm device and reports to the police, and reminds sufferer and nurse, and liquid-transport pipe-line causes transfusion speed to slow down because stop up.
Reminiscences 1 hangs over infusion bottle 2 belows by snap ring 11, and snap ring 11 is the annular of 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 snap ring below.
When snap ring is stuck on bottleneck, fuselage is positioned at bottle neck below.
At fuselage, on the end face of upper tubing 5, be provided with top-down groove 15, groove is semicircle, and its diameter is greater than the diameter of upper tubing; During use, upper tubing is positioned at transfusion tube seat.
Because infusion apparatus is all disposable, but reminiscences is need to be reusable, in order to prevent the cross infection that may cause that is connected between infusion apparatus and reminiscences, therefore, disposable isolator is set between reminiscences and infusion apparatus, just can effectively prevents the cross infection that may cause that is connected between infusion apparatus and reminiscences.
Above-described embodiment is only for interpretation purposes of the present invention, and is not limitation of the present invention, and those skilled in the art, in essential scope of the present invention, make a variety of changes or substitute, and also should belong to protection category of the present invention.
