Examples
Referring to fig. 1, the present invention provides the following technical solutions: a disposable negative pressure skin suction device comprises a piston adjusting pull handle 1, a pull rod non-return device 2, an air vent 3, a rebound spring 4, a negative pressure suction cylinder 5, a rubber piston 6, a sealing ring 7 and a negative pressure chassis 8, wherein the piston adjusting pull handle 1 is inserted in the center of the negative pressure suction cylinder 5, the pull rod non-return device 2 is fixed on one side, located on the piston adjusting pull handle 1, of the top of the negative pressure suction cylinder 5, the rubber piston 6 slides in the negative pressure suction cylinder 5, the sealing ring 7 is arranged at the bottom port of the negative pressure suction cylinder 5, and the negative pressure chassis 8 is arranged at the bottom of the negative pressure suction cylinder 5.
In the embodiment, the device comprises a piston adjusting pull handle 1, a pull rod check device 2, an air vent 3, a rebound spring 4, a negative pressure suction tube 5, a rubber piston 6, a sealing ring 7 and a negative pressure chassis 8, wherein the piston adjusting pull handle 1 is connected with the negative pressure suction tube 5 through the rebound spring 4, the upper end of the rebound spring 4 props against a negative pressure cavity, and the lower end of the rebound spring props against the rubber piston 6, and the device comprises the negative pressure chassis 8 and the negative pressure suction tube 5 with negative pressure value scales and is used for fixing axillary skin, and the skin is expanded and flattened inwards by the chassis protruding in the cavity, so that the large sweat glands are conveniently cut; and the pull rod backstop 2 is matched and clamped with the piston adjusting pull handle 1 according to the principle shown in figure 1, so that the operation is simpler, more time-saving and labor-saving, the traction injury around the incision is light, the postoperative recurrence rate is lower, and the complications are less; the negative pressure principle is good in effect when being used for adsorbing the skin, the negative pressure suction tube 5 is convenient to hold by hands at best, and the negative pressure base plate 8 is convex so as to be convenient for unfolding the skin.
Specifically, one end of a rubber piston 6 is fixed with a piston adjusting pull handle 1, and a rebound spring 4 is sleeved on the surface of a pull rod backstop 2 in a negative pressure suction tube 5.
In this embodiment, rebound spring 4 has a cushioning effect, and simultaneously can drive rubber piston 6 to rebound in negative pressure suction tube 5.
Specifically, one end of the rebound spring 4 is not fixed to the rubber piston 6, and the other end of the rebound spring 4 is not fixed to the inner wall of the negative pressure suction tube 5.
In this embodiment, rebound spring 4 adjusts to slide stably, has pressure assurance and cushioning effect, fixed mounting structure.
Specifically, the top of the negative pressure suction tube 5 is provided with an air vent 3.
Specifically, the negative pressure suction tube 5 is communicated with the cavity of the negative pressure chassis 8.
In this embodiment, the air holes 3 are used for guiding the flow, so that the negative pressure is formed inside the negative pressure suction tube 5.
The utility model discloses a theory of operation and use flow: the conventional skin preparation of the operation area, the patient lifts the upper limbs of the patient over the head and places the upper limbs of the patient on the top of the head, after the conventional disinfection and drape of the operation field and the local infiltration anesthesia work, an oval negative pressure chassis 8 of the disposable negative pressure skin suction device is aligned with the skin of the axillary hair area of the patient, the skin of the operation area is lightly pressed and flattened, a piston is pulled to adjust a pull handle 1, a rebound spring 4 is driven to compress through a pull rod backstop 2, the gas above a rubber piston 6 is discharged through a vent hole 3, a negative pressure environment is formed in a cavity below the rubber piston 6 so as to achieve the purpose of adsorbing and fixing the skin of the operation area, the arc-shaped convex negative pressure chassis 8 supports the adsorbed skin to enable the skin to be in an arc-shaped expansion and expansion state, so that the gland of the large sweat gland can be conveniently removed in the operation, in order to achieve the safe negative pressure environment, a graduated scale for marking the negative pressure value is arranged on a negative pressure suction, a rubber ring sealing ring 7 is arranged at the contact position of the negative pressure suction tube 5 and the skin, so that air is prevented from entering the negative pressure suction tube 5 to reduce the negative pressure value, the skin in the operation is ensured to be continuously fixed, meanwhile, the pull rod backstop 2 is matched with a piston to adjust the pull handle 1 to abut against, the pull rod backstop 2 is prevented from rebounding under the pressure of air pressure and a rebound spring 4, after the negative pressure chassis 8 attracts and fixes the skin, the skin angle is adjusted by lifting and swinging the hand-held negative pressure suction tube 5 to change the orientation of the negative pressure chassis 8 so as to be compliant with the operation to cut off the gland, when the gland is cut off, the piston is released to adjust the pull handle 1 by pressing the pull rod backstop 2, the piston adjusts the pull handle 1 to return to the lower end of the negative pressure suction tube 5 under the action of external air pressure and the rebound spring 4, the negative pressure environment disappears.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
