FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.
As shown in fig. 1, the present invention provides an anesthetic administration device, which includes a first three-way valve 1, a second three-way valve 2, a check valve 3, a first extension pipe 4, a second extension pipe 5, a third extension pipe 6, and a fourth extension pipe 7.
The first three-way valve 1 has a first port 11, a second port 12 and a third port 13, and the first port 11, the second port 12 and the third port 13 are communicated with each other. The second three-way valve 2 has a fourth port 21, a fifth port 22 and a sixth port 23, and the fourth port 21, the fifth port 22 and the sixth port 23 are communicated with each other. The second port 12 of the first three-way valve 1 is connected to the fourth port 21 of the second three-way valve 2, and the first three-way valve 1 and the second three-way valve 2 are connected to each other. The second port 12 of the first three-way valve 1 is connected to the fourth port 21 of the second three-way valve 2 using the first rotary connector 10 to reduce the pipe drop.
One end of the check valve 3 is connected to the first port 11 of the first three-way valve 1, so that the first three-way valve 1 and the check valve 3 are connected, and the check valve 3 can prevent the anesthetic from flowing backwards.
One end of the first extension pipe 4 is connected to the fifth port 22 of the second three-way valve 2, so that the second three-way valve 2 and the first extension pipe 4 are connected. One end of the first extension pipe 4 is connected to the fifth port 22 of the second three-way valve 2 using the second rotary connector 20 to reduce the pipeline dropping.
One end of the second extension pipe 5 is connected to the third port 13 of the first three-way valve 1, and connects the first three-way valve 1 and the second extension pipe 5. One end of the second extension pipe 5 is connected to the third port 13 of the first three-way valve 1 using a third rotary connector 30 to reduce the pipeline dropping.
One end of the third extension pipe 6 is connected to the sixth port 23 of the second three-way valve 2, so that the second three-way valve 2 and the third extension pipe 6 are connected to each other. One end of the third extension pipe 6 is connected to the sixth port 23 of the second three-way valve 2 using a fourth rotary connector 40 to reduce the pipeline dropout.
One end of the fourth extension pipe 7 is connected to the other end of the check valve 3, so that the check valve 3 and the fourth extension pipe 7 are connected, and the check valve 3 is located between the first three-way valve 1 and the fourth extension pipe 7.
When the intravenous anesthesia device is used, the other end of the first extension tube 4 is connected with the vein of a patient, the other ends of the second extension tube 5 and the third extension tube 6 are respectively connected with an anesthetic, and the other end of the fourth extension tube 7 is connected with an intravenous drip, so that the anesthetic and the intravenous drip can be conveyed to the patient end, and the intravenous anesthesia operation can be carried out. First three-way valve is connected with the check valve, and the check valve can prevent that narcotic from flowing against the current, can prevent that the narcotic that second extension pipe and third extension pipe were exported from flowing toward the direction of fourth extension pipe for narcotic can only flow toward the direction of first extension pipe and patient's end, can effectually avoid leading to the risk of reviving in the patient art because of vein narcotic flows against the current.
The above is, of course, only a specific application example of the present invention, and the scope of the present invention is not limited in any way. In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by using equivalent substitutions or equivalent transformations fall within the scope of the present invention.
