A control valve 33 is installed on the first connecting tube 31 and the second connecting tube 32. By installing a connector 2 at the head of the negative pressure suction pipe 1, it is convenient to cooperate with the shunt tube group 3 through the connector 2, and then the negative pressure suction pipe 1 and the shunt tube group 3 can be connected to each other through the connector 2, and by designing the shunt tube group 3 into a structure that cooperates with the first connecting tube 31 and the second connecting tube 32, it can be ensured that when negative pressure suction is performed through the negative pressure suction pipe 1, the adsorption of two pipes can be achieved at the same time, and in order to ensure the flexibility of use, control valves 33 can be installed on both the first connecting tube 31 and the second connecting tube 32, so that when in use, the control valve 33 can be used to control the opening and closing of the first connecting tube 31 and the second connecting tube 32 respectively, and then during the actual suction operation, one of the three methods of opening the first connecting tube 31 alone, opening the second connecting tube 32 alone, and opening the first connecting tube 31 alone and the second connecting tube 32 together can be selected as needed.

[0026] Working principle: When actual negative pressure suction is used, the first connecting tube 31 and the second connecting tube 32 can be connected to different parts of the patient (such as the nasal cavity and the abdomen) respectively, so that when suction of the nasal cavity is needed, the control valve 33 on the first connecting tube 31 can be turned to open the first connecting tube 31, and when ascites drainage is needed, the control valve 33 on the second connecting tube 32 can be turned to open the second connecting tube 32. When the patient needs to perform suction and ascites drainage operations at the same time, the first connecting tube 31 and the second connecting tube 32 can be opened at the same time, and they can be closed when suction is not needed.

[0027] Example 2

[0028] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a double-head negative pressure suction device includes a negative pressure suction tube 1, a connector 2 is installed at the head of the negative pressure suction tube 1, the connector 2 is sealed and connected to the negative pressure suction tube 1, and a shunt tube group 3 is also installed on the connector 2, the shunt tube group 3 includes a first connecting tube 31 and a second connecting tube 32, and one end of the first connecting tube 31 and the second connecting tube 32 are both sealed and connected to the connector 2. By installing the connector 2 at the head of the negative pressure suction tube 1, it is convenient to cooperate and connect with the shunt tube group 3 through the connector 2, and then the negative pressure suction tube 1 and the shunt tube group 3 can be connected to each other through the connector 2, and the connector 2 can also select the conduction mode of the shunt tube group 3, and by designing the shunt tube group 3 into a structure in which the first connecting tube 31 and the second connecting tube 32 cooperate, it can be ensured that when the negative pressure suction is performed through the negative pressure suction tube 1, the adsorption of two pipes can be achieved at the same time.

[0029] Reference Figure 2 and Figure 6 As shown, the connector 2 includes a flow dividing shell 21 and a sealing cover 22. The sealing cover 22 is buckled on the upper end surface of the flow dividing shell 21, and the sealing cover 22 is sealed and engaged with the flow dividing shell 21. The structure of the connector 2 is set to ensure that the negative pressure suction tube 1 and the flow dividing tube group 3 are connected to each other through the flow dividing shell 21, and the sealing cover 22 is set on the flow dividing shell 21 to ensure that the upper end of the flow dividing shell 21 is sealed by the sealing cover 22, so that the negative pressure suction tube 1 and the flow dividing tube group 3 can be sealed, so as to facilitate stable suction operation.

[0030] Reference Figure 6 As shown, the sealing cover 22 includes a hard middle cover 221, a full-through upper cover 222 and a partition lower cover 223. The full-through upper cover 222 and the partition lower cover 223 are respectively arranged at the upper and lower ends of the hard middle cover 221, and the full-through upper cover 222 and the partition lower cover 223 are both fixedly connected to the hard middle cover 221. By fixing the full-through upper cover 222 and the partition lower cover 223 on the upper and lower ends of the hard middle cover 221, respectively, it is easy to install the sealing cover 22 by choosing to install it in the diverter shell 21 through the full-through upper cover 222 or to install it in the diverter shell 21 through the partition lower cover 223. When the full-through upper cover 222 is installed in the diverter shell 21, it can ensure that the first connecting pipe 31 and the second connecting pipe 32 are opened in both channels, while when the partition lower cover 223 is installed in the diverter shell 21, only a single channel can be opened or not opened.

[0031] Reference Figure 6As shown, the full-through upper cover 222 includes an upper plug plate 2221 and a support frame 2222. The upper plug plate 2221 is fixedly mounted on the upper end surface of the hard middle cover 221, and the support frame 2222 is fixedly mounted on the upper end surface of the upper plug plate 2221. The structural setting of the full-through upper cover 222 ensures that the upper plug plate 2221 can be inserted into the diverter shell 21 to achieve sealing during installation, and then supported in the diverter shell 21 by the support frame 2222 to ensure more stable installation.

The lower plug plate 2231 is fixedly mounted on the lower end surface of the hard middle cover 221, and the partition plate 2232 is fixedly mounted on the lower end surface of the lower plug plate 2231. The structural setting of the partition lower cover 223 ensures that the lower plug plate 2231 can be inserted into the diverter shell 21 to achieve sealing during installation, and the partition plate 2232 is supported in the diverter shell 21, so that the partition plate 2232 can be used to select the partition operation, and the angle of the partition plate 2232 in the diverter shell 21 can be changed to meet different usage requirements.

[0033] Reference Figure 2 As shown, an indicator mark 2211 is fixedly installed on the outer side of the hard middle cover 221, and a scale 1 211 and a scale 212 corresponding to the indicator mark 2211 are arranged on the outer side of the diverter shell 21. The installation angle of the hard middle cover 221 is easily determined by setting the indicator mark 2211. When the indicator mark 2211 is aligned with the scale 1 211, the first connecting tube 31 can be closed and the negative pressure suction tube 1 is connected to the second connecting tube 32, so that the second connecting tube 32 can be used alone. When the indicator mark 2211 is aligned with the scale 2 212, the second connecting tube 32 can be closed and the negative pressure suction tube 1 is connected to the first connecting tube 31, so that the second connecting tube 32 can be used alone.

[0034] Working principle: When actual negative pressure suction is used, the first connecting tube 31 and the second connecting tube 32 can be connected to different parts of the patient (such as the nasal cavity and the abdomen) respectively. When the first connecting tube 31 and the second connecting tube 32 need to be used at the same time, the full-through upper cover 222 on the sealing cover 22 can be installed in the diversion shell 21 to achieve sealing. When a single channel needs to be opened, the partition lower cover 223 on the sealing cover 22 can be installed in the diversion shell 21 to achieve sealing. At the same time, the indicator mark 2211 can be determined to correspond to scale one 211 or scale two 212 according to the channel to be opened. When adsorption is not required, the negative pressure suction tube 1 and the diversion tube group 3 can be separated by the partition plate 2232.

For those skilled in the art, the utility model can have various modifications and changes. 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.
