Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a disposable infusion device. Background Art

[0002] Intravenous infusion pumps used clinically are mainly divided into two categories based on infusion capacity and infusion accuracy, namely infusion pumps and micro-injection pumps. Infusion pumps are mainly used for conventional infusion, usually large-volume and high-flow-rate intravenous infusion. The minimum flow rate can be controlled at 1m / h, the accuracy is ±5%, and the single dose can reach 9999mL; micro-injection pumps are suitable for micro-injection and precise drug delivery. The minimum flow rate can be controlled at 0.1ml / h, the accuracy can be as high as ±2%, and the single dose is related to the specifications of the syringe. The maximum injection dose is 100ml.

[0003] During use of the current disposable infusion device, medical staff are required to inject part of the drug solution into the drug bottle through a syringe, and judge the dosage by observing the scale on the outer surface of the drug bottle. In actual use, the scale can only be observed at a close distance, which does not play a good display role. Medical staff need to observe the watch and their accumulated experience to judge the time for the second dose, which is very inconvenient to use.

[0004] To this end, we provide a disposable infusion device to solve the above problems. Utility Model Content

In actual use, the scale can only be observed at a close distance, which does not provide a good display effect.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a disposable infusion device, comprising an injection bottle, wherein the bottom of the injection bottle is connected to a fixed tube, the internal thread of the fixed tube is connected to a connecting plug, the bottom of the connecting plug is connected to an infusion tube, and the top of the infusion tube is connected to a core rod;

[0008] A display assembly is provided on one side of the liquid injection bottle, and the display assembly includes a first connecting tube, the first connecting tube is connected to one side of the fixed tube, the other end of the first connecting tube is connected to a measuring tube, a scale is provided on the surface of the measuring tube, and a suspended ball is provided inside the measuring tube.

[0009] The utility model is further configured such that a limiting block is fixedly connected to the interior of the measuring tube, and a color separation coating is provided on the surface of the measuring tube.

[0010] The present invention is further configured such that the top end of the measuring tube is connected to a second connecting tube, and the other end of the second connecting tube is connected to a liquid injection bottle.

[0011] The utility model is further configured such that a buckle is fixedly connected to the top of the liquid injection bottle, and a hanging strap is sleeved on the surface of the buckle.

[0012] The present invention is further configured such that the bottom of the infusion tube is connected to a liquid inlet tube, and a rubber stopper is installed on the surface of the liquid inlet tube.

[0013] The present invention is further configured such that a sealing groove is provided on the top of the connecting plug, and a sealing ring is installed inside the sealing groove.

[0014] The utility model has the following beneficial effects:

[0015] The utility model is provided with a display component. After the medical staff injects the medicine liquid into the injection bottle, the medicine liquid will enter the measuring tube through the first connecting tube. When the medicine liquid is injected into the measuring tube, the suspended ball will move upward due to the buoyancy and move simultaneously with the increase or decrease of the medicine liquid. The surface of the measuring tube is provided with three groups of gradient transparent coatings of different colors, so that the medical staff can observe the position of the suspended ball at a distance, which can effectively improve the display effect and facilitate the medical staff to administer medicine in time.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
