Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a suction head with a control switch. Background Art

[0002] During the operation, the suction device is an indispensable tool for sucking bleeding, exudate, pus, contents in thoracic viscera, etc. generated during the operation to ensure a clear surgical field and reduce the chance of contamination. The principle of the suction device is to create a negative pressure state at its suction head, so that the atmospheric pressure will squeeze the substances outside the suction head towards the suction head, thus completing the "suction" effect.

[0003] However, the traditional suction devices have obvious deficiencies in design: these suction devices usually do not have a control switch, and as long as the connected negative pressure exists, they will continuously suck, and cannot be precisely controlled according to the surgical needs. This continuous suction method may cause pollutants such as bacteria and dust in the operating room air to be sucked into the blood recovery reflux tank together. When this recovered blood containing bacteria is re-infused into the patient's body, it may cause postoperative infection and seriously affect the patient's recovery process.

[0004] Therefore, developing a suction device that can intelligently control the suction process and effectively avoid pollutants from entering the recovered blood is of great significance for improving the safety and efficiency of the operation. Content of the Utility Model

Detailed implementation manners

[0019] The technical solution of this patent will be further described in detail below in combination with the specific implementation manners.

[0020] As Figure 1 shown, a suction head with a control switch includes a hollow suction head body 1. An interface end 2 and a suction end 3 are respectively arranged at both ends of the suction head body 1. The interface end 2 is used to connect to a negative pressure machine, and the suction end 3 is used to suck out bleeding, exudate, pus, contents in thoracic viscera, etc. generated during the operation. An opening 4 is formed on the side wall of the suction head body 1 near the interface end 2, and the opening 4 is a strip-shaped opening 4. A slider switch 5 that can slide up and down at the opening 4 is arranged at the opening 4. The slider switch 5 is connected to a blocking device 6 for blocking the suction end 3. The blocking device 6 is arranged inside the suction head body 1. By sliding the slider switch 5 at the opening 4, the opening and closing of the blocking device 6 to the suction end 3 are controlled. It can be opened and used when the suction head is needed, and can be closed when not needed.

[0021] Further, sliding grooves 7 for facilitating the sliding of the slider switch 5 are arranged on both sides of the opening 4. The sliding grooves 7 are arranged inside the suction head body 1 and are integrally connected with the suction head body 1. The slider switch 5 can slide along the sliding grooves 7. The slider switch 5 includes a sliding part 8 arranged inside the suction head body 1 and a push block 9 connected to the sliding part 8. The sliding part 8 is used in cooperation with the sliding grooves 7 to enable the slider switch 5 to slide along the sliding grooves. The push block 9 is arranged outside the suction head body 1 for easy operation. A limiting strip 10 for limiting the slider switch 5 is arranged at the bottom of the opening 4. The limiting strip 10 is arranged outside the suction head body 1 and is integrally connected with the suction head body 1.

[0022] Further, the blocking device 6 includes a first folding part 11, a second folding part 12 and a liquid blocking part 13. The first folding part 11 is connected to one end of the slider switch 5; the second folding part 12 is respectively connected to the first folding part 11 and the liquid blocking part 13; the liquid blocking part 13 is arranged at a position close to the suction end 3. Among them, the cross-section of the liquid blocking part 13 is T-shaped, and a through hole 14 communicating with the suction end 3 is formed in the liquid blocking part 13, so that during the use of the suction head, the contents can be sucked into the suction head body 1 through the suction end 3 and the through hole 14. A protrusion 18 corresponding to the through hole 14 is arranged on the second folding part 12 for blocking the through hole 14.

[0023] Furthermore, first folding portions 11 are each provided with a first fold angle 15 between them and the slider switch 5, second fold angles 16 are each provided between the first folding portions 11 and the second folding portions 12, and third fold angles 17 are each provided between the second folding portions 12 and the liquid blocking portions 13. Opposite inclined surfaces are provided on the two first fold angles 15, the two second fold angles 16, and the two third fold angles 17 to facilitate the folding of the first folding portions 11 and the second folding portions 12. The plugging device 6 of the present utility model can be made of rubber, plastic, or other materials capable of achieving the above functions.

[0024] When using the suction head to suck, by default, the position of the slider switch 5 is at the top of the opening, and it can be used without pushing the slider switch 5 downward. When the suction head is not in use, push the slider switch 5 downward. At this time, the first folding portion 11 and the second folding portion 12 are folded. The second folding portion 12 is folded above the liquid blocking portion 13 and covers the liquid blocking portion 13. The protrusion 18 of the second folding portion 12 exactly covers the through hole 14 of the liquid blocking portion 13 to block the suction end 3. The present utility model can control the opening and closing of the plugging device 6 for the suction end 3 by the up and down sliding of the slider switch 5 in the opening 4.
