The skin separatorThis utility model relates to the skin treating apparatus, especially the skin separator.
Vitiligo is a kind of common skin disease, aspect dermatosis such as treatment vitiligo, need carry out the cultivation of epidermis cell transplanting and epidermis cell, and this just needs a kind of skin separation instrument finish above-mentioned work.Skin separation instrument kind commonly used is a lot, but mostly adopts vacuum air pump as critical piece, causes whole instrument complex structure, volume big, and operation is difficult for, and power consumption is big, noise is strong, and is in the use, influential to patient's emotion.The negative pressure skin separometer of heating that Yuncheng County, Shandong Province medical apparatus and instruments seven factories produce just adopts vacuum air pump as core component, thereby has above-mentioned obvious defects, and costs an arm and a leg and make it can not get extensive use.
The purpose of this utility model is at above-mentioned deficiency, provides a kind of simple in structure, easy to operate, does not need electric energy, cheap skin separator.
Technical solution of the present utility model is such: a kind of skin separator, comprise pump bowl, vacuum table, suction cup, the termination of bleeding that it is characterized in that pump bowl has connection tube, there is one section hard tube the connection tube front portion, vacuum table is connected on the hard tube, in the junction of hard tube and pump bowl, there is a piston to be arranged in the hard tube, and a little activity space is arranged; Suction cup is connected to the other end of connection tube, and the junction at both is provided with valve.
This utility model has replaced electronic vacuum draw pump with manual pump bowl, and in conjunction with the special construction of connection tube, vacuum table, piston and valve, only pass through allows manual aspiration, can make in flexible pipe and the suction cup and form negative pressure, thereby play the isolating effect of skin, simple in structure, easy to operate easily and cost low, can extensively be promoted the use of.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the upward view of this utility model suction cup.
As shown in Figure 1, this skin separator comprises pump bowl 1, vacuum table 2, suction cup 3, the principle of bleeding of pump bowl 1 is opposite with ordinary bicycle inflator principle just, the termination of bleeding at pump bowl 1 has connection tube 4, connection tube 4 has certain length, one section hard tube 13 is arranged in its front portion, vacuum table 2 is connected on the hard tube 13, near pump bowl 1 one sides, in the junction of hard tube 13, there is a piston 5 to be arranged in the hard tube 13, in this end with pump bowl 1, the diameter of hard tube 13 is big slightly, piston 5 inside can rotate flexibly, and when the piston cup 7 of pump bowl 1 resetted under the interconnect function of spring 6, piston 5 can be under gas pressure, this end of sealing hard tube 13 makes to be negative pressure state in suction cup 3 and the connection tube 4.Suction cup 3 is connected on the other end of connection tube 4, and be provided with valve 8 in both junctions, suction cup 3 be shaped as the bowl-shape of back-off, be provided with bracing frame 9 in it, bracing frame 9 is positioned at suction cup 3 rims of a cup one side direction sunken inside, become an arc,, be convenient to pick up skin for the rim of a cup place of suction cup 3 leaves certain space.
During use, suction cup 3 covers on the skin, and one holds the holding rod 11 on the pump bowl 1, spurs then to move after pull bar 12 makes piston cup 7 by piston rod 10, in pump bowl 1, form negative pressure, thereby make piston 5 open connection tube 4, this negative pressure is picked up the skin that covers in the suction cup 3, when continuous pulling pull bar 12, when making the interior negative pressure value of connection tube reach set point, valve-off 8 makes suction cup 3 interior negative pressure constant, thereby makes the skin that is picked up be in the state of picking up always.Piston cup 7 in the pump bowl 1 resets under the propelling of spring 6 simultaneously, waits for next time and using.In the time will pulling up suction cup 3, open valve 8 at last, air admission suction cup 3, thus can easily take out suction cup 3.
