Abstract
The utility model discloses a hand vacuum fat sucking injector, composed of a needle cylinder, a piston, a piston rod of the piston and a needle tube. The main body of the needle cylinder is composed of two coaxial sleeve tubes, one of the two coaxial sleeve tubes is outside and is a metal sleeve tube with a window, and the inner coaxial sleeve tube is a glass transparent tube with scientific analysis scale or a plastic transparent tube with scientific analysis scale. The two coaxial sleeve tubes have a front cover and a back cover, and a columniform snap ring is arranged in the middle of the piston rod. The tail end of the needle tube is provided with a one-way onstate device. When the one-way onstate device is cut off, the piston rod is pull to cause the piston rod to be fixed at the edge of a hole at the back cover of the needle cylinder, thus previously generating and maintaining vacuum negative-pressure fat sucking operation. The utility model has the advantages of reasonable design, simple structure and convenient operation.
Description
This utility model relates to a kind of liposuction syringe, especially hand-held vacuum liposuction syringe.
Along with improving constantly of people's living standard, adopt medical means such as operation, medicine that people's body or looks are beautified and improved, become modern's consumption fashion.And the fatty sucking-off of body local plumpness is external or fat directly injected other position of human body, to reach local weight-reducing or moulding again purpose, be again the most common a kind of.In the prior art, Chinese patent 96215480.6 " rotary clamp type suction lipectomy syringe " is disclosed to be existing Dispoable medical syringe to be improved form, and design has card on syringe outer tube, has draw-in groove on the plunger.It both can be used for aspirating the subcutaneous fat operation, can be used for fat again and injected.But, cause practical operation still inconvenient because of structure is too simple.
The purpose of this utility model is exactly in order to provide a kind of reasonable in design, simple in structure, easy to operate, safe and reliable, can produce the hand-held vacuum liposuction syringe that negative pressure of vacuum also can be kept the liposuction operation in advance.
For achieving the above object, the technical scheme that this utility model is dealt with problems is: a kind ofly can give the hand-held vacuum liposuction syringe that produces earlier negative pressure of vacuum and can keep the liposuction operation, it comprises syringe, be positioned at intraluminal piston of syringe and piston rod thereof and be loaded on the needle tubing of syringe bottom.The syringe main body is made of two coaxial sleeves, and is outer for having the metal canula of oval window, interior for indicating graduated glass of volume or plastic, transparent pipe.Syringe two ends are with forward and backward lid, and protecgulum and metal canula are hinged, and its center has the trepanning of a female thread; Bonnet is threaded with metal canula, and its center has a rectangular opening.Piston rod is the metal rectangular cylinder, and front end is equipped with the piston of sealing gasket, closely matches with the inwall of plastic tube in the syringe; The centre of piston rod is provided with several gardens post snap ring, and the rear end links to each other with the push-and-pull handle.Needle tubing is forward and backward to be the metal needle and the backshank of hollow, and syringe needle has a plurality of side openings, and backshank is provided with Device in one-way on state, and end is not outer has screw thread to be connected with the centre bore of syringe protecgulum.
After taking abovementioned technology, compared with prior art, good effect of the present utility model is:
Since the backshank of needle tubing be provided with unidirectional conducting and put.Therefore,, pull back piston rod and can make formation negative pressure of vacuum in the syringe, produce negative pressure of vacuum earlier, make this utility model before needle tubing enters human body, can not form negative pressure of vacuum to reach to give as long as disconnect Device in one-way on state.
2. because the centre of piston rod has garden post snap ring, syringe bonnet center has rectangular opening, therefore, when pulling back piston rod, as long as piston rod garden post snap ring aligns with the bonnet central rectangular aperture, rotation push-and-pull handle, garden post snap ring can make things convenient for and be securely fixed in the edge of bonnet rectangular opening, do not have complicated structure and operation, only need to rotate push-and-pull getting final product fixed piston.When making vacuum draw, piston is stopped gliding move to the front end of syringe, to keep ideal negative pressure of vacuum, keep the liposuction operation.User is arbitrarily release easily also, makes piston and piston rod thereof return to home position and elimination vacuum.So, reasonable in design, simple in structure, easy to operate, safe and reliable.
3. the glass of syringe or plastic, transparent pipe are with the piston of sealing gasket and needle tubing disassembling, assembling and replacing convenient, in order to disposable use, and health, safety.
Below in conjunction with drawings and Examples this utility model hand-held vacuum liposuction syringe is described in further detail.
Fig. 1 is a hand-held vacuum liposuction syringe construction outline drawing.
As can be seen from Figure 1, hand-held vacuum liposuction syringe mainly is made up of syringe 4, the needle tubing that is positioned at syringe 4 intraluminal pistons 7 and piston rod 2 thereof and is loaded on syringe 4 bottoms, syringe 4 main bodys are made of two coaxial sleeves, outer for having the metal canula of ellipse garden shape window, interior for indicating graduated glass of volume 50～60ml or plastic, transparent sleeve pipe.Syringe two ends are with the forward and backward lid of metal, and protecgulum 8 is hinged with metal canula.Its center has the trepanning of a female thread.Bonnet 3 is threaded with metal canula, and its center has a rectangular opening.Piston rod 2 is the metal rectangular cylinder, and front end is equipped with the piston 7 of rubber gasket, closely matches with the inwall of plastic tubes in the syringe 4, and the centre of piston rod 2 has 1～3 garden post snap ring 5, and the rear end links to each other 1 with push-and-pull.Needle tubing is forward and backward to be the metal needle 11 and the backshank 10 of hollow, and external diameter is 4～6 millimeters, and internal diameter is 2～4 millimeters, has 1～5 side opening before the syringe needle 11, and backshank 10 is provided with Device in one-way on state 9, and end is outer to have screw thread to be connected with the centre bore of syringe 4 protecgulums 8.During practical operation, earlier the backshank 10 of needle tubing is tightened with protecgulum 8 centre bores of syringe, disconnect Device in one-way on state 9, firmly pull back piston rod 2, as long as the garden post snap ring 5 of piston rod 2 is alignd with the rectangular opening of syringe bonnet 3, rotate push-and-pull 1, can make garden post snap ring 5 be securely fixed in the edge of bonnet 3 rectangular openings, form and keep negative pressure of vacuum.Program is inserted subcutaneous layer of fat with needle tubing in accordance with regulations then, connects Device in one-way on state 9, can aspirate subcutaneous fat.After being filled, extract needle tubing immediately, the fat in the syringe 4 is pushed give in the container of getting ready earlier, reach the purpose of local weight-reducing.If desired its fat is injected other position of human body, then fat that can sucking-off is external is repeatedly with pure fat being injected other position after normal saline flushing, precipitation, the separation, to reach again moulding purpose again.
This utility model is mainly used in beauty treatment and orthopedic local weight-reducing or moulding again, also can be used for the vacuum draw that other fluid (as venom, pus) is gone up in medical treatment.
