Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a negative pressure suction device with a negative pressure pipeline protection function. Background Art

[0002] The negative pressure suction device is used to remove bleeding, exudate, pus, and contents of chest organs during surgery to reduce contamination. The principle of the negative pressure suction machine is to create a negative pressure state at the negative pressure head after the negative pressure machine draws negative pressure, and then the atmospheric pressure will squeeze the material outside the negative pressure head into the negative pressure head, thereby achieving the purpose of negative pressure suction.

[0003] When the existing negative pressure suction device is working, if the user fails to replace the liquid inside the container in time, the liquid in the container will flow back to the negative pressure suction device through the pipeline under the influence of the negative pressure suction device, thereby affecting the negative pressure suction device.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 efforts are within the scope of protection of the present invention.

[0026] Example 1:

[0027] like Figure 1-5 As shown, the present invention provides a negative pressure suction device with a negative pressure pipeline protection function, comprising a body 1, the top of the body 1 is open, a limiting pipe 4 is fixedly provided at the upper end of the inner bottom wall of the body 1, and a protection component 3 is provided inside the limiting pipe 4;

[0028] The protection component 3 includes a limiting rod 5 and a blocking block 6. The limiting rod 5 is arranged inside the limiting pipe 4. A fixing groove 12 is opened on one side of the limiting pipe 4. The blocking block 6 is arranged inside the limiting pipe 4 and the blocking block 6 is arranged on the outside of the limiting rod 5.

[0029] Specifically, a cover plate 11 is provided at the upper end of the body 1. A second connecting pipe 8 is provided on the top wall of the cover plate 11. The other end of the connecting pipe 8 is connected to a suction device. Advantageously, the cover plate 11 provides protection, preventing liquid from flowing out of the top of the body 1. The suction device draws the liquid, which then enters the interior of the body 1 through the second connecting pipe 8.

[0030] Specifically, the top wall of the cover plate 11 is provided with a connecting pipe 1 (7), located to the right of the connecting pipe 2 (8). The connecting pipe 1 (7) and the limiting pipe 4 are integrally provided. The other end of the connecting pipe 1 (7) is fixedly connected to a negative pressure suction device. Advantageously, under the action of the negative pressure suction device, liquid is drawn through the suction device and then enters the interior of the body 1 through the connecting pipe 2 (8).

[0031] Specifically, a circular groove 9 is formed on the top wall of the block 6 and extends through the block 6. A limit rod 5 is disposed within the groove 9, and a limit assembly 2 is disposed at the upper end of the bottom wall of the body 1. Advantageously, the block 6 rises with the rising liquid, thereby blocking the connecting pipe 7.

[0032] Example 2:

[0033] like Figure 1-5 As shown, as an improvement to the previous embodiment, the limiting assembly 2 includes a limiting pipe 4, a limiting rod 5, and a limiting block 10. The limiting rod 5 is fixedly mounted on the upper end of the inner bottom wall of the main body 1, and two limiting blocks 10 are fixedly mounted inside the connecting pipe 1 7. Advantageously, the limiting pipe 4 and limiting rod 5 provide a limiting effect during the movement of the blocking block 6. Simultaneously, the limiting blocks 10 also provide a limiting effect, preventing the blocking block 6 from continuing to move upward due to the effect of the negative pressure suction device.

[0034] When in use, the device sucks liquid through the suction device under the action of the negative pressure suction device, and the liquid then enters the interior of the main body 1 through the connecting pipe 2 8. Since a fixing groove 12 is provided on one side of the limiting pipe 4, the liquid can enter the interior of the limiting pipe 4, so the block 6 can also rise with the rise of the liquid. In this process, the setting of the limiting pipe 4 and the limiting rod 5 has a limiting effect until the top of the block 6 touches the limiting block 10. At this time, the block 6 blocks the connecting pipe 1 7, and the block 6 can no longer move, which also prevents the block 6 from continuing to move upward due to the effect of the negative pressure suction device. At the same time, the liquid will not affect the negative pressure suction device. Finally, the block 6 can be made of rubber.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
