The mounting groove 11 is provided with a fixing mechanism 7 to prevent the dedicated infusion tube 2 from falling off.

[0030] The fixing mechanism 7 includes: a protective cover 71 and an anti-falling block 72;

[0031] The anti-falling block 72 is fixedly installed on the side of the dedicated infusion tube 2, and fixed card slots 12 are provided at the tops of both sides of the installation slot 11, and fixed card strips 712 are fixedly installed on both sides of the protective cover 71, and the fixed card strips 712 are clamped with the fixed card slots 12. An anti-falling card slot 711 is provided on the protective cover 71, and the anti-falling card slot 711 is clamped with the dedicated infusion tube 2, and the anti-falling block 72 contacts the inner wall of the protective cover 71.

[0032] Among them, the design of connecting the collecting plate 3 with multiple input tubes 4 and an output tube 5 forms a multi-channel design to meet the clinical use requirements of multiple drugs;

[0033] The fixed clamping strip 712 and the fixed clamping slot 12 are clamped into a buckle locking structure, so that the protective cover 71 is fixed in the installation slot 11, so that the protective cover 71 can play a sealing effect; when the protective cover 71 in the fixing mechanism 7 is clamped with the dedicated infusion tube 2 by the anti-dropping clamping slot 711, it not only prevents the dedicated infusion tube 2 from being disconnected by external force, but also closes the protective cover 71 to play a sealing effect, preventing the joint between the input tube 4 and the dedicated infusion tube 2 from being contaminated, thereby facilitating disinfection and anti-pollution;

[0034] Among them, since there are multiple input tubes 4, the infusion channel can be added at any time, the operation is convenient, and the multiple infusion channels meet the needs of rapid infusion, so it is practical;

[0035] The collection tray 3, the output tube 5 and the output extension tube 6 are made of transparent materials, which are convenient for observing whether there is an infusion reaction, and can be embedded with a filter membrane to filter out infusion particles and impurities;

[0036] In a preferred embodiment, as shown in the attached Figure 1-4 As shown, a fixing piece 713 is fixedly mounted on the protective cover 71, so that the fixing piece 713 can be used to control the opening and closing of the protective cover 71;

[0037] In a preferred embodiment, as shown in the attached Figure 1-4 As shown, the shape of one end of the fixed clip 712 contacting the inner wall of the installation groove 11 is set to an arc shape, and the material of the fixed clip 712 is set to a highly elastic silicone material; so that the shape and material of the fixed clip 712 can be used to control the opening and closing of the protective cover 71 more smoothly.

[0038] In a preferred embodiment, as shown in the attached Figure 1-4 As shown, the minimum distance between the input tube 4 and the anti-dropping slot 711 is smaller than the minimum distance between the end face of the dedicated infusion tube 2 and the anti-dropping block 72, the diameter of the input tube 4 is larger than the diameter of the dedicated infusion tube 2, and the outer wall of the end of the dedicated infusion tube 2 is tightly fitted with the inner wall of the end of the input tube 4; so that the anti-dropping block 72 can be used to ensure that there is no gap between the ports where the dedicated infusion tube 2 and the input tube 4 are connected, and no leakage will occur when the drug solution flows from the dedicated infusion tube 2 to the input tube 4.

[0039] In a preferred embodiment, as shown in the attached Figure 1-4 As shown, one-way valves for guiding the drug solution to flow toward the collecting tray 3 are installed at the ends of the multiple input pipes 4 close to the collecting tray 3 .

[0040] When the dedicated infusion tube 2 is connected to the input tube 4 of the connector body 1, the one-way valve can be used to prevent backflow and blockage of the tube so that the liquid medicine flows along the input tube 4 into the collecting tray 3, and then flows from the output tube 5 to the output extension tube 6, and finally completes the intravenous injection operation; thus, the one-way valve is used to ensure that there is no blood return and reflux, and to prevent tube blockage;

[0041] In a preferred embodiment, as shown in the attached Figure 1-4 As shown, the number of input tubes 4 is at least 3; so that at least three input tubes 3 can be used to deliver drugs, thereby achieving a rapid infusion effect, and the unused infusion channel can use a one-way valve to avoid backflow in the input tube 4.

[0042] A method for using a multi-channel infusion extension tube, the specific operation is as follows:

[0043] Step 1: Prepare the equipment. If an infusion channel is required, connect the output interface of the drug to be delivered to the input end of the corresponding dedicated infusion tube 2; then proceed to step 2;

[0044] Step 2: After opening the protective cover 71 through the fixing piece 713, insert the output end of the dedicated infusion tube 2 to be used into the input tube 4; then proceed to step 3;

[0045] Step 3: close the protective cover 71 through the fixing plate 713, and at the same time, connect the anti-dropping slot 711 with the corresponding dedicated infusion tube 2, so that the anti-dropping block 72 contacts the inner wall of the fixing plate 713; then proceed to step 4;

[0046] Step 4: Check the flow of the drug solution according to the transparent connector body 1, and promptly connect the output extension tube 6 to the intravenous injection input end to be injected into the patient's body;

[0047] Among them, the connector body 1 is designed with transparent material to facilitate the observation of drug-drug reactions;

[0048] Step 5: Determine whether the remaining infusion channels need to be used. If necessary, connect the output interface to be delivered with the corresponding input end of the dedicated infusion tube 2; then perform steps 2 and 3 in sequence, and return to step 5; otherwise, the infusion is finished and all devices can be removed.

[0049] In a preferred embodiment, as shown in the attached Figure 1-4 As shown, during the infusion in steps 1 to 5, the dedicated infusion tube 2 needs to be kept above the output extension tube 6 so as to utilize gravity for infusion.

[0050] In a preferred embodiment, as shown in the attached Figure 1-4 As shown, in step 1 to step 5, if disinfection operation is required, the protective cover 71 is clamped on the dedicated infusion tube 2 to keep the input tube 4 inside the connector body 1 in a closed state before the disinfection operation can be performed.
