Furthermore, an air suction opening is formed in the first negative pressure hemisphere and/or the second negative pressure hemisphere.
Furthermore, a one-way valve is arranged at the air exhaust port. Air is pumped to the one-way valve by using the air pump, so that air leakage is avoided.
Furthermore, the inner end of the first negative pressure hemisphere is connected with the inner end of the second negative pressure hemisphere.
Furthermore, the outer end of the first negative pressure hemisphere is detachably connected with the outer end of the second negative pressure hemisphere.
Furthermore, a buckle is arranged between the outer end of the first negative pressure hemisphere and the outer end of the second negative pressure hemisphere. The two connected negative pressure hemispheres can be connected in a sealing mode through the buckles after the angle positions are determined.
Furthermore, 3-9 puncture needle fixing points are arranged on the first negative pressure hemisphere. According to the practical situation, the puncture needle fixing points are selected correspondingly, and the puncture needle is fixed by the puncture needle fixing piece.
Preferably, 5 puncture needle fixing points are arranged on the first negative pressure hemisphere. The interval angle of the fixed positions of the 5 puncture needles is about 30 degrees.
Furthermore, a plurality of puncture needle fixing points are uniformly distributed on the same half circumference of the first negative pressure hemisphere along the circumferential direction.
Further, the diameter of the first negative pressure hemisphere is 4-6 cm.
In the utility model, the puncture needle fixing part is preferably made of silica gel, can naturally form an airtight state when no puncture needle is inserted, and can form an airtight connection with a corresponding fixed-point sealing piece when the puncture needle is fixed. An air exhaust port is arranged on the negative pressure hemisphere on one side, and when the negative pressure hemispheres on the two sides are closed, the negative pressure hemispheres are closed by a buckle.
When the puncture needle is used, firstly, an operator performs puncture positioning, after the puncture is in place, an assistant selects a proper puncture needle fixing position, the two negative pressure hemispheres are closed, the negative pressure hemispheres are slightly pressurized and fixed on the skin, the connecting hollow needle is used for exhausting air outwards from the air exhaust port, so that negative pressure is formed in the closed negative pressure hemispheres, and the puncture needle is stably fixed by taking local skin and a small amount of subcutaneous tissues as fulcrums. Because the general puncture operation is often short, the influence of transient negative pressure compression on local skin and subcutaneous tissues is not large, and if the operation time exceeds 15 minutes, the buckle can be loosened, so that the skin can rest.
Compared with the prior art, the utility model has the characteristics of it is following:
1) the operation is convenient and fast: the utility model discloses need not must numerous and complicated joining process, only need operation assistant help art person fix the pjncture needle at suitable angle after the art person accomplishes the puncture, seal the straining with both sides negative pressure hemisphere, the empty needle is bled and is made the negative pressure in the negative pressure hemisphere can.
2) The flexibility is good: the utility model discloses a plurality of pjncture needle fixed point can make puncture angle nimble change.
3) Good repeatability: if the puncture position is more than one, the operation process can be repeated, and the puncture needle is fixed again.
