one end of each hose 2 is respectively communicated with the two fluid infusion ports 12, and the other ends of the two hoses are respectively connected with a heparin cap or a positive pressure connector;
two conduit clamps 3 are respectively arranged on the two hoses 2 and are respectively used for opening or closing the corresponding hoses 2.
In this embodiment, the two fluid-filling ports 12 are respectively connected with the hose 2, and the other ends of the hose 2 are respectively connected with heparin caps.
When two kinds of liquid medicine are needed to be supplemented to a patient at the same time, after the transfusion port 11 in the expansion joint of the embodiment of the utility model is connected with the heparin cap at the tail end of the special needle 100 of the implantable drug delivery device, the two kinds of liquid medicine can be supplemented at the same time through the special needle of the implantable drug delivery device connected with the expansion joint, and the drawing is referred to as figure 2;
referring to fig. 3, when the patient needs to be supplemented with three kinds of liquid medicines at the same time, after the infusion port 11 in the expansion joint is connected with the heparin cap at the tail end of the special needle of the implantable drug delivery device, the infusion port 11 of the other expansion joint is connected with the heparin cap at the liquid supplementing port 12, so that the three kinds of liquid medicines can be supplemented simultaneously through the special needle of the implantable drug delivery device connected with the expansion joint.
By analogy, medical staff can adjust the number of expansion joints arranged at the tail end of the special needle of the implantable drug delivery device according to the medical requirements of patients, so that the special needle of the implantable drug delivery device can realize simultaneous drug supplementing of one, two or more liquid medicines, and the use is more convenient.
The three-way joint 1 may also be provided with three fluid-supplementing ports or more.
In order to facilitate connection, when the tail end of the special needle of the implantable drug delivery device is a heparin cap or a positive pressure connector, the infusion port 11 is a nipple, so that the three-way connector 1 is conveniently inserted into the heparin cap or the positive pressure connector through the nipple.
Referring to fig. 4-6, in this embodiment, the catheter clip 3 includes an upper arm 31 and a lower arm 32, the upper arm 31 includes an upper connecting portion 311, a pressing portion 312 and a clamping portion 313 that are sequentially disposed, a limiting member 314 is disposed on an upper end surface of the clamping portion 313, the lower arm 32 includes a lower connecting portion 321, a pressing portion 322 and a limiting portion 323 that are sequentially disposed, the upper connecting portion 311 is connected with the lower connecting portion 321, a boss matched with the clamping portion 313 is disposed on the limiting portion 323, a limiting groove 324 is disposed on a lower end surface of the boss, the upper arm 31 can rotate downward relative to the lower arm 32 until the clamping portion 313 is located below the boss, and the limiting groove 324 is clamped into the limiting member 314.
The upper end of the pressing part 312 is provided with anti-slip patterns, and the pressing part 312 and the pressing part 322 are used for mutually matching and pressing the hose therebetween to close the hose.
Referring to fig. 4, which is a schematic structural diagram of the catheter clamp 3 when the first hose 3 or the second hose 4 is opened, a medical staff presses the pressing portion 312 to rotate the upper arm 31 relative to the lower arm 32 until the upper arm 31 is clamped at the lower end of the boss and closes the hose, and referring to fig. 5, which is a schematic structural diagram of the catheter clamp 3 when the catheter clamp 3 closes the second hose 3, at this time, the limiting groove 324 extends into the limiting piece 314 to relatively fix the upper arm 31 and the lower arm 32, so as to avoid the upper arm 31 from being separated from the side portion of the lower arm 32.
In this embodiment, the limiting member 314 is a bar-shaped protrusion, the limiting member 314 is distributed along the width direction of the upper arm 31, and the limiting groove 324 is a bar-shaped groove matched with the limiting member 314.
After the limiting groove 324 extends into the limiting piece 314, the limiting piece 314 and the limiting groove 324 are structured so that the upper arm 31 can only move along the width direction relative to the lower arm 32, and the upper arm 31 cannot move along the width direction relative to the lower arm 32 due to the interconnection of the upper arm 31 and the lower arm 32, so that the bar-shaped limiting piece 314 and the limiting groove 324 cooperate to limit the upper arm 31 to move horizontally relative to the lower arm 32, and the upper arm 31 is prevented from falling out from the side part of the lower arm 32.
When the hose needs to be opened, the limiting part 323 of the lower arm 32 is pushed to rotate and move away from the upper arm 31, so that the limiting groove 324 rotates and moves away from the limiting piece 314, and the clamping connection between the upper arm 31 and the lower arm 32 is released.
Referring to the drawings, the cross section of the limiting groove 324 is arcuate, which facilitates the rotation of the limiting groove 324 relative to the limiting member 314 to release the clamping connection between the upper arm 31 and the lower arm 32.
The limiting member 314 and the limiting groove 324 are in a straight strip shape or a wavy shape or a zigzag shape, and can be continuous or discontinuous wavy or zigzag shape, so that the limiting member 314 and the limiting groove 324 are ensured to be mutually and stably limited.
In other embodiments, the limiting member 314 is hemispherical, and the limiting groove 324 is a recess matching the limiting member 314.
Of course, the present utility model is not limited to the above-described embodiments, and those skilled in the art can make equivalent modifications and substitutions without departing from the spirit of the present utility model, and these equivalent modifications and substitutions are included in the scope of the present utility model as defined in the appended claims.
