Background

The disposable infusion pump is a medical device product which is regulated by the power generated by the elastic force of the liquid storage bag of the pump and continuously conducts intravenous infusion at a certain speed and in a trace amount.

At present, disposable infusion pumps are widely used for continuously infusing drugs such as analgesics, chemotherapeutics, somatostatin and the like through veins clinically, and the treatment effect is influenced even the safety of patients is harmed when the drug infusion speed is too slow or too fast. When the medicine is clinically infused, two ways of infusion are sometimes adopted, and a clinical nurse can judge the smoothness of one way of infusion of the infusion pump according to whether the other way of infusion is smooth or not. However, when these drugs are infused by a single infusion pump, clinical medical staff can roughly judge the accuracy and smoothness of infusion by weighing the infusion pump or observing the size of a bag in the pump with naked eyes, and the accuracy and the rigor of infusion are lacked. The common specifications of the clinical disposable infusion pump are generally 2ml/h and 5ml/h, and due to the slow flow rate, medical staff cannot judge whether the infusion path is blocked or not from the appearance of the infusion pump by naked eyes, so that the situation that the blockage of the infusion path cannot be found and treated in time at the first time possibly exists, the continuity of the drug infusion is interrupted, and the drug curative effect is influenced and even the safety of a patient is damaged after the completion time of the infusion is shortened.

Detailed Description

As shown in fig. 1 and fig. 2, in one embodiment, the infusion pump comprises a protective shell 100, a liquid storage bag 200 and an infusion tube 300, wherein the liquid storage bag 200 is arranged inside the protective shell 100, a medicine adding port 110 is arranged on the protective shell 100, the medicine adding port 110 is communicated with the liquid storage bag 200, a protective cap 111 is arranged on the medicine adding port 110, one end of the infusion tube 300 is communicated with the liquid storage bag 200, a puncture unit 400 is arranged at the other end of the infusion tube 300, and a flow monitor 500 and a blockage dredging mechanism 600 are arranged on the infusion tube 300.

When infusing the liquid medicine, the medical staff injects the medicine into the liquid storage bag 200 through the medicine adding port 110, wherein the liquid storage bag 200 is positioned on the protective shell 100 and protected by the protective shell 100, and after the medicine is added, the medicine adding port 110 is covered with the protective cap 111. Be equipped with flow monitor 500 on transfer line 300 for flow in the monitoring transfer line, when the jam appears in the transfer line, flow monitor 500 detects the flow reduction in transfer line 300 to give medical personnel with the jam condition feedback that appears, so that medical personnel in time handle through dredging stifled mechanism 600, avoid influencing treatment because of the jam. By providing the flow rate monitor 500, the presence or absence of clogging is determined, and thus, the presence or absence of clogging is determined from the appearance without a nurse.

As shown in fig. 4, the block-dredging mechanism 600 comprises a housing 610 and a balloon 310 arranged on the infusion tube 300, the infusion tube 300 passes through the housing 610, the balloon 310 is positioned in the housing 610, and a pressure unit for pressing the balloon 310 is arranged in the housing 610.

When blockage occurs in the infusion pipeline, the medical staff applies pressure to the balloon 310 through the pressure applying unit, the balloon 310 is flattened, after the force of the pressure applying unit is removed, suction force can be generated when the balloon is restored to the original state, and the medicine blocked on the infusion pipeline is sucked away, so that the infusion pipeline is dredged, and the problem of pipeline blockage is solved quickly.

Further, the pressing unit comprises a pressing rod 710, a spring 720 and a spring pressing rod 730, wherein one end of the pressing rod 710 penetrates through the shell 610 to be pressed against the balloon 310, the spring pressing rod 730 is transversely arranged on the pressing rod 710, two oppositely arranged supporting plates 800 are arranged on the inner wall of the shell 610, a cylinder 810 is arranged on the supporting plate 800, the spring 720 is arranged in the cylinder 810, pressing heads 731 inserted into the cylinder are arranged at two ends of the spring pressing rod 730, and the pressing heads 731 are pressed against the spring 720.

Medical personnel can push down through depression bar 710, exert pressure for sacculus 310, and after the pressure on depression bar 710 was removed, depression bar 710 returned initial position under the effect of spring 720, and medical personnel can be through pushing down depression bar 710 repeatedly, until dredging infusion pipe.

As shown in fig. 2 and 3, the protective case 100 includes an inner case 120 and an outer case 130, the inner case 120 is covered outside the reservoir 200, and the inner case 120 and the outer case 130 are integrated and filled with gas therebetween.

As the reservoir 200 is added to the medication, the reservoir 200 expands as the medication is added. The protective housing 100 adopts a two-layer structure, and when external force extrudes the protective housing 100, the force acts on the outer housing 130, and the force cannot be directly applied to the liquid storage bag 200, so that the deformation and displacement of the liquid storage bag 200 due to the acting force are avoided.

The flow monitor 500 is an infrared drop number sensor, which is provided with an alarm 510. The infrared drop number sensor is provided with a threshold value, when the drop number of the medicine in each unit time of the infusion tube 300 is lower than the set threshold value, the situation that the drop number is reduced due to blockage in the pipeline is explained, and medical staff is reminded to rapidly handle the medicine through the alarm 510.

Preferably, the alarm 510 includes a red warning lamp and an audible alarm. And an alarm signal is sent out through a red alarm lamp and a sound alarm.
