Abstract
Description
Technical Field
[0001] The utility model relates to an infusion piece, in particular to a multi-channel infusion kit. Background Art
[0002] At present, in order to reduce damage to blood vessels and relieve pain to patients during intravenous infusion in clinical practice, usually only one infusion point is established on the patient's blood vessels. Usually, infusion needles, indwelling needles, PICC catheters and other instruments are connected to blood vessels to build vascular access. When intravenous infusion is given, it will enter the human blood through the vascular access. In clinical practice, different drugs need to be infused into patients for treatment, such as intravenous anesthesia, chemotherapy, etc., and multiple infusion tubes are often used for combined infusion. This requires multiple infusion lines to be connected to the vascular access. At present, there are many problems in clinical practice when multiple lines are connected and used through one or more tees. First, there is a lack of overall drug resistance research on special drugs such as anesthesia and chemotherapy drugs after combined use of various components, resulting in the risk of cracking and leakage of the equipment. After the three-way combination, the applicability has not been confirmed, and the intended use of the product will also change. Secondly, the arbitrary combination of multiple pipelines will cause cross-flow and liquid reflux between multiple channels, and the connection of each part will often leak. Utility Model Content
[0003] The utility model provides a multi-channel infusion kit for overcoming the defects of cross-flow and backflow problems caused by combining multi-channel pipelines in the prior art and poor combination and inapplicability of multiple pipelines temporarily assembled on site by clinical medical staff.
[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0005] The utility model discloses a multi-channel infusion kit, comprising a main circuit, a multi-channel component is installed on the main circuit, an extension pipeline is connected below the multi-channel component, and a terminal pipeline is connected behind the multi-channel component. The main circuit comprises a pipeline, and a puncture device, an exhaust drip bucket and a regulator are arranged on the pipeline in sequence. The multi-channel component comprises a three-way valve and a backflow prevention device connected through an interface.
[0006] Furthermore, the backflow prevention device is a one-way valve, a check valve or a non-return valve, which is used to prevent the backflow of the liquid medicine and the cross-flow of liquids between multiple channels.
[0007] Furthermore, the rotary handle at the junction of each channel on the multi-channel component has a color code of a different color to facilitate the distinction between different liquid medicines in each channel.
[0008] Furthermore, each channel on the multi-channel assembly can be equipped with a pressure infusion device such as an infusion pump or a syringe pump to achieve the purpose of precise infusion and process monitoring.
[0009] Furthermore, the terminal pipeline is provided with a liquid medicine filter for filtering the liquid medicine and an external conical joint that can be matched and connected with other instruments in sequence.
[0010] The beneficial effects achieved by the utility model are: the product structure is simple and clear, the operation is convenient in clinical practice, and the processing is convenient. The structure abandons the previous single-channel structure of the infusion tube, solves the problems of cross-flow and reflux caused by the combination of multi-channel pipelines, avoids the inconvenience caused by temporary assembly on site by clinical medical staff and the risk of poor combination and inapplicability of multiple pipelines. The infusion kit adopts its own multi-channel pipeline to meet the clinical multi-channel use requirements, and solves the safety hazards caused by the variety of drugs. The infusion is safer and more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0016] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0017] Example 1
[0018] like Figure 1-3 As shown, a multi-channel infusion kit includes a main line 1, on which a multi-channel component 2 is installed, and an extension pipeline 3 is connected below the multi-channel component 2, and a terminal pipeline 4 is connected behind it.
[0019] The multiple channel pipes of the infusion kit can be different types and functions of intravenous infusion pipes, such as infusion sets, analgesic pipes, chemotherapy pipes, and infusion extension pipes. By combining with the multi-channel component 2 with the anti-backflow device 2-1, the universal pipes are connected to the liquid medicine filter after the channels merge to form an integral kit.
[0020] The channels of infusion kits usually appear in two forms. One is a main line 1 and one or more extension lines 3. The main line 1 includes lines 1-4, which are provided with puncture devices 1-1, exhaust drip buckets 1-2 and regulators 1-3 in sequence. Lines 1-4 are connected to form the main line 1 by bonding with each other, and are used to be suspended on an infusion stand to achieve gravity or pump-powered infusion. The bypass is an extension line 3, which is mainly used for clinical infusion, temporary fluid addition, fluid replenishment, combined infusion, etc. The other two are that each main line 1 is composed of extension lines 3, which are used for clinical infusion, temporary fluid addition, fluid replenishment, combined infusion, etc.
[0021] The materials used in each part of the infusion kit are made of chemically resistant medical materials. Each interface of the multi-channel component 2 is equipped with an anti-backflow device 2-1, which is a one-way valve, a check valve or a non-return valve. The inlet of the multi-channel component 2 is only allowed to enter the liquid to prevent the liquid from flowing back, and the outlet of the multi-channel component 2 is only allowed to discharge the liquid to prevent the liquid from flowing back. Ensure that there is no cross-flow between the channels to prevent liquid backflow. Since each channel can be infused with different liquid medicines, the handles at the junction of each channel on the multi-channel component 2 will have different color codes to facilitate the distinction of liquid medicines. The pipelines of each channel on the infusion kit can be used with pressure infusion equipment such as infusion pumps and injection pumps to achieve the purpose of accurate infusion and process monitoring. The end pipeline 4 of the infusion kit is also equipped with a liquid filter 4-1 to ensure that the liquid medicine infused in each channel can be filtered through the liquid filter 4-1. The end of the infusion kit is an outer conical connector 4-2, which can be matched and connected with other instruments, such as indwelling needles, central venous catheters, etc.
[0022] The number of channels of the infusion kit is 2 to 8. The multi-way assembly is composed of multiple independent three-way valves 2-2 and multiple anti-backflow devices 2-1 connected as a whole through a conical interface. It can also be an integrated multi-way valve and an anti-backflow device 2-1 connected to each interface, or the Luer cone connection between the rotary valves and the rotary valves and the anti-backflow devices is eliminated, and they are directly integrated together to form a unified whole, forming an anti-backflow multi-way connection plate. The multi-way assembly is connected to each channel pipeline through a standard conical connector, so that each channel pipeline merges into an infusion path at the multi-way assembly.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
