As an alternative embodiment, referring to fig. 2 and 5, a through hole 402 communicating with the drainage channel 401 is formed at the side of the grip portion 4, and the through hole 402 is communicated with the outside air, so that the stimulation and suction portion 1 connected with the negative pressure device can suck blood, tissue fluid, a washing solution, and the like when the through hole 402 is blocked.
The through hole 402 on the grip portion 4 is convenient for a user to open and close the suction function when holding the grip portion 4. Specifically, when the through hole 402 is blocked, a negative pressure environment is formed in the stimulation and suction portion 1 to which the negative pressure device is connected, and blood and tissue fluid near the target site are sucked into the fluid channel 101 due to the pressure difference and are sucked through the drainage channel 401. After the liquid is sucked, the switch on the negative pressure device needs to be matched by others because the operator performs the operation. In the above-described configuration of the present embodiment, the operator himself or herself can open the fluid passage 101 in the stimulus-suction portion 1 to the outside atmosphere by releasing the through hole 402, and the suction function is closed because there is no pressure difference between the target portion and the fluid passage 101.
The structure is simple, the use is more convenient, and the opening and closing of the suction function can be conveniently switched by an operator through one hand of the operation holding part 4.
The end face of the holding part 4 is provided with a connecting port for communicating with a negative pressure device, and the connecting end and the holding part are connected into a whole through injection molding.
The particular features, structures, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
