[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Although the present invention specification may include embodiments in many different forms, for some preferred embodiments described in detail in the specification and shown in the drawings, it should be understood that: these contents disclosed in the present invention specification should be regarded as schematic illustrations of the principles of the present invention, and these shown embodiments are not intended to limit the scope of protection of the present invention.

[0028] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In order to further clarify the aspects, viewpoints and advantages of the present disclosure, the present disclosure will be described in more detail by referring to the specific embodiments in the accompanying drawings.

[0030] According to an embodiment of the present disclosure, the present invention provides a multi-way valve device mainly used for performing angiography.

[0031] Figure 1-2 is a schematic diagram showing a multi-way valve arrangement. Figure 2 As shown, the multi-way valve device mainly includes a valve body 1, a control button 2, a valve stem 3 and a base body 4, as well as a selection component 5 and a nut 6. The high-pressure pipeline channel is connected to the opening A of the base body 4. Generally, the multiple fluid channels include a converter channel, a saline channel and a contrast medium channel. One end of the high-pressure pipeline channel is connected to a catheter inserted into the patient's body.

[0032] In addition, a selection component 5 is provided at the distal end of the valve body 1. According to the position of the control button 2, the selection component 5 can select at least one channel from the converter channel, the saline channel and the contrast medium channel, connect the selected channel to the valve stem 3, and can connect or cut off the communication between the converter channel and the high-pressure pipeline channel. In this case, when the control button is in the first position, the selection component 5 can select the high-pressure pipeline channel connected to the valve stem 3. However, when the control button is in the second position, the selection component 5 can select the converter channel connected to the high-pressure pipeline channel. At this time, only the contrast medium channel can be connected to the valve stem, and the converter channel and the saline channel are closed. When the control button 2 is in the third position, the selection component 5 can select the converter channel connected to the high-pressure pipeline channel and the saline channel connected to the valve stem 3. At this time, the contrast medium channel is closed. When the control button 2 is in the first position, the converter channel and the saline channel are closed. When the control button 2 is in the third position, the converter channel and the high-pressure pipeline channel are closed. Only the saline channel is connected to the valve stem 3. When performing angiography, a three-ring syringe is required. According to an embodiment of the present disclosure, there is provided an angiography injection system, which includes a multi-way valve switching device, an insertion connector and a three-ring syringe.

[0033] The valve stem 3 is arranged in the valve body 1 and fixed on the control button 2. Here, the valve stem includes a channel for transmitting fluid. An extension is provided at the distal end of the valve stem and the end close to the valve body 1. Therefore, relative to the valve body 1, when the control button 2 rotates radially, the valve stem 3 rotates radially synchronously therewith. In other words, the valve stem 3 is static relative to the control button 2.

[0034] The distal end of the valve body 1 is connected to the base body 4. Preferably, the base body 4 can be connected to the valve body 1 by a nut. The base body 4 can be connected to a plurality of fluid channels and a high-pressure pipeline channel. Figure 2As shown, the plug connector 7 is a connection device for connecting a multi-way valve switch device to a three-ring syringe. The plug connector 7 includes a base 9 having a hole, and a plurality of connection pins 10 are evenly arranged on the base. The connection selection component 5 is located at the distal end of the valve body 1. According to the position of the control button 2, the selection component 5 can select at least one channel from the converter channel, the saline channel and the contrast agent channel, connect the selected channel to the valve stem 3, and can connect or cut off the communication between the converter channel and the high-pressure pipeline channel. When the control button is in the first position, the selection component 5 can select the high-pressure pipeline channel connected to the valve stem 3. However, when the control button is in the second position, the selection component 5 can select the converter channel connected to the high-pressure pipeline channel. At this time, only the contrast agent channel can be connected to the valve stem, and the converter channel and the saline channel are closed. When the control button is in the third position, the selection component 5 can select the converter channel connected to the high-pressure pipeline channel and the saline channel connected to the valve stem 3. At this time, the contrast agent channel is closed. When the control button is in the first position, the converter channel and the saline channel are closed. When the control button is in the third position, the converter channel and the high-pressure pipeline channel are closed. Only the brine channel is connected to the valve stem 3.

[0035] The valve body 1 is a cylinder with a hollow cavity, including a distal end and a proximal end. The proximal end of the valve body 1 is connected to a control button 2 that can rotate radially but not axially. In actual operation, relative to the valve body 1, the control button 2 can be selectively rotated to three positions, namely, a first position, a second position, and a third position. Among them, the first position is located at the center position and is regarded as the starting position. By rotating the control button 2, different functional channels can be switched for angiography according to actual needs.

[0036] The selection assembly 5 includes a first valve plate 51 and a second valve plate 52. The first valve plate 51 is located at the distal end of the valve body 1 and is fixed to the valve stem 3. The first valve plate 51 can rotate with the rotation of the valve stem 3, so it can be called a power valve plate. The second valve plate 52 is fixed to the base body 4. Therefore, when the valve stem 3 rotates, the first valve plate 51 and the second valve plate 52 achieve relative radial rotation. In this way, different functional channels can be switched as needed during angiography.

[0037] During angiography, a three-ring syringe is required. According to an embodiment of the present disclosure, a multi-way valve device for angiography is provided, which includes a valve body, a control button, a valve stem, a base body, a selection assembly and a nut. The device also includes a plug connector and a three-ring syringe.

[0038] In the above steps, during the angiography process, a syringe is required to push the contrast agent. Therefore, the operator is required to turn these switches at the same time to control the injection and flow of the contrast agent. By using the three-way valve device of the present invention, the angiography operation can be simplified and the safety and efficiency of the operation can be improved.

[0039] The folding valve device is therefore adapted to allow the control button 2 to rotate with the rotation of the three-ring syringe 8. Therefore, the operation of the multi-way valve device can be controlled simply by rotating the three-ring syringe.

[0040] Using the multi-way valve device of the present invention to perform angiography includes the following specific steps:

[0041] Step 1, connect the saline tube to the saline channel;

[0042] Step 2, turn the control button to position 3 (i.e., the third position), pull back the syringe and infuse saline;

[0043] Step 3, turn the control button to position 2 (i.e., the second position);

[0044] Step 4, connecting the high-pressure pipe to the contrast medium channel;

[0045] Step 5, push the syringe to remove the air in the converter channel, and then connect the converter to the converter channel;

[0046] Step 6, disconnect the high-pressure pipeline and the contrast medium channel, and connect the contrast medium pipeline to the contrast medium channel;

[0047] Step 7: Connect the high pressure pipe to the conduit;

[0048] Step 8. Now the control button is in position 2 (i.e., the second position), connect the converter to the catheter to monitor the blood pressure signal; close the saline channel, connect the contrast medium channel to the syringe, and pull back the syringe to infuse the contrast medium;

[0049] Step 9. Turn the control button to position 1, close the converter channel to protect the converter, connect the high-pressure pipe to the valve stem, push the syringe to inject the contrast agent and perform angiography;

[0050] Step 10: Repeat steps 8 and 9 to prepare for the next injection;

[0051] Step 11, turn the control button to position 3, connect the converter to the catheter to monitor the blood pressure signal, and close the contrast agent channel;

[0052] Among them, the three fluid channels include a converter channel, a saline channel and a contrast agent channel.
