Embodiment
As depicted in figs. 1 and 2, in a kind of isolator, infusion process, reminiscences 1 is hung up on infusion bottle 3, in reminiscences One isolator 2 is set between infusion bottle.
As shown in figure 3, described reminiscences 1 mainly includes the first snap ring 11, fuselage 12;Fuselage 12 is provided with and connects mouth 13, The one end for connecing mouth is connected with isolator, and the other end is provided with pressure sensor, and pressure sensor is connected to control by signal wire Device;Warning device and control device are additionally provided with fuselage.Control device is divided the pressure signal that pressure sensor is transmitted Analysis judges, decides whether to open warning device alarm.
As shown in Figure 4, Figure 5 and Figure 6, described isolator 2 include upper signal pipe 21, under connect mouth 22 and air bag 23;Upper letter Number pipe and under connect muzzle and connect to form a cavity, air bag is located in cavity;Air bag is the hollow capsules of one end open, openend Edge is connected with the inwall of cavity, and cavity is divided into two independent spaces, and one is signal space, and one is that air-flow is empty Between, the openend of air bag connects mouth under;Upper signal pipe 21 is socketed provided with interface with connecing mouth 13.
Outstanding suction nozzle and outlet nozzle are provided with mouth being connect under airflow space, outlet nozzle and air inlet pipe 4 One end socket, suction nozzle communicates with outside air, provided with pressure check valve in suction nozzle.
The other end of air inlet pipe is provided with air inlet needle, and air inlet needle is pricked into bottle neck;Air bag can be in the presence of negative pressure to entering The direction contraction distortion of valve;The deformation of air bag causes signal space to expand, so as to produce negative pressure, negative pressure signal is by connecing mouth 13 Pass to pressure sensor;When the pressure of the negative pressure in airflow space is less than the unlatching value of pressure check valve, pressure check valve It is closed, when the pressure of negative pressure is more than the unlatching value of pressure check valve, pressure check valve could open air inlet.
When decoction, which flows away, causes the negative pressure that is produced in infusion bottle sufficiently large, the air in dynamic air inlet pipe and airflow space is inhaled Into supplement so that air inlet pipe and airflow space also produce negative pressure, direction contraction distortion from air bag to suction nozzle;When air-flow is empty Interior negative pressure continues to increase, and until the negative pressure in airflow space is more than the unlatching value of pressure check valve, pressure check valve is opened, Extraneous air flows into airflow space and air inlet pipe, adds in infusion bottle, the pressure inside and outside infusion bottle is obtained balance, air The negative pressure for stopping entering in infusion bottle, air inlet pipe and airflow space reduces, and air bag replys original shape, and pressure check valve is closed.
Described pressure check valve mainly includes valve ball 24, spring 25, the second snap ring 26;In suction nozzle close to airflow space Inwall be provided with bayonet socket, during installation, valve ball 24 is filled in into suction nozzle from airflow space, then be pressed into spring 25, finally by second Snap ring 26 is snapped on the bayonet socket of suction nozzle inwall.
When airflow space is in negative pressure state, negative pressure can overcome the prestressing force of spring to the suction of valve ball, then valve ball Moved in suction nozzle to the direction of airflow space, the gap of extraneous air between valve ball and suction nozzle inwall enters air inlet Mouth, enters back into airflow space.When the negative pressure of airflow space reduces, negative pressure can not overcome the prestressing force of spring to the suction of valve ball When, valve ball is pushed back original position by spring, blocks the import of suction nozzle, prevents the air in the external world from entering.Therefore, valve ball and suction nozzle Inlet end between suction nozzle diameter of bore be less than valve ball diameter.
Before use, the liquid pin that draws for being located at upper dropper end is penetrated into bottle cap, regulation switch is opened, decoction is affected by gravity By drawing liquid pin into upper dropper, subsequently into drop capsule, and then lower dropper is flowed into, arrange the air in pipe under the promotion of decoction Go out, after oozing two or three drop from the transfusion needle positioned at lower dropper end when decoction, then transfusion needle is inserted on the remaining needle of patient, built The path of transfusion is erected, then by adjusting the speed that switch-mode regulation is infused well.
Due to by adjust the decoction in the speed that switch-mode regulation is infused well, infusion bottle be it is at the uniform velocity dirty, therefore, It is also stable by the frequency that extraneous air is sucked in infusion bottle that enough negative pressure are produced in bottle, and at this moment, opening is located at fuselage On switch start control device work, the pressure signal that control device is transmitted with 1-2 minute record pressure sensors first, control The information such as signal intensity when air inlet frequency when device processed records normal infusion and air inlet, and by these information as base Quasi- value, then, the pressure signal that control device constantly sends pressure sensor is compared with a reference value recorded, and is determined Whether warning device alarm is opened.
During normal infusion, because bottle inner liquid medicine amount is sufficient, liquid level, which is not less than, draws liquid pin, and return-air is intermittent.Only when When liquid level is declined to a certain extent, the negative pressure of suction air enough can be just produced in bottle, only negative pressure reaches to a certain degree, just meeting Air-breathing, when air enters infusion bottle, make the pressure that decoction is produced and gas is produced in bottle pressure sum substantially with atmospheric pressure phase Deng, stop suction, the at the uniform velocity lower drop input human body of decoction, until the negative pressure produced in bottle reaches that the degree of air-breathing just can be again again Air-breathing.
When liquid level is less than air inlet syringe needle, due to the separation without liquid, in airflow space, air inlet pipe and infusion bottle Air communication, therefore, when decoction continue to it is dirty when, air in infusion bottle can be made to produce negative pressure, it is empty in air inlet pipe and air-flow Between will produce continuous negative pressure, when negative pressure be more than pressure check valve unlatching value when, pressure check valve open, extraneous air Into airflow space and then enter infusion bottle, decoction is can continue to lower drop.
When airflow space produces negative pressure, negative pressure makes Direction distortion of the air bag to suction nozzle, signal space is produced negative pressure, The signal that pressure sensor returns to control device is exactly continuous negative pressure signal, and signal frequency can also change, and work as control When device detects continuous negative pressure signal and frequency and is higher than a reference value, control device opens warning device alarm, remind sufferer and Nurse's transfusion is near completion.
When the signal intensity that control device monitors pressure sensor return is consistent with a reference value, but air inlet frequency is less than base The half of quasi- value, opens warning device alarm, reminds sufferer and nurse, liquid-transport pipe-line because blocking causes transfusion speed to slow down.
Reminiscences 1 hangs over the lower section of infusion bottle 2 by the first snap ring 11, and the first snap ring 11 is the annular of a side opening, first Snap ring is stuck on the bottleneck of infusion bottle;Be provided with the contiguous block 14 that extends downwardly in the lower edge of the first snap ring, contiguous block it is following Edge is connected with the roof of fuselage 12, fuselage is hung over below the first snap ring.
When the first snap ring is stuck on bottleneck, fuselage is located at below bottle neck.
Towards top-down groove 15, groove is provided with the end face of upper tubing 5 it is semicircle in fuselage, its diameter is big In the diameter of upper tubing;In use, upper tubing is located in transfusion tube seat.
Due to infusion apparatus be all it is disposable, but reminiscences be need reuse, in order to prevent infusion apparatus with Connection between reminiscences may caused by cross-infection, therefore, set between reminiscences and infusion apparatus it is disposable every From device, it becomes possible to effectively prevent that the connection between infusion apparatus and reminiscences may caused cross-infection.
