Description
Technical field
The present invention relates to field of medical device, particularly a kind of autologous fat collection, purification and transplantation device.
Background technology
In the medical field, after human body own fat being acquired, purified, then itself affected part is subcutaneously injected
Filling treatment, because instant effect, effect are good, is widely used in treatment, soft group of the hand of such as subcutaneous pitting defect or deformity
Knit atrophy（It is commonly called as chicken feet hand）Treatment, the treatment that genitals reshaping is moulded, the chest enlarge treatment of female breast, the moulding of buttocks control
The places such as treatment.It is divided into three steps, the first step in treatment：First the position more than the human body own fat gathers fat；Second step：
Oil droplet in fat after collection, manadesma, watery blood mixture are subjected to isolation of purified；3rd step：Effective lipochondrion after purifying
Human body corresponding site is expelled to be treated.
When carrying out fat acquisition in existing technology, one kind is acquired with syringe, and this mode of operation has expense
When, the laborious, shortcoming that collection fat mass is few, and lean in itself by operator, when fat utilization rate is low, the fat mass of collection
Needs of performing the operation are harder to meet, the time entirely performed the operation can be also therefore extended, overlong time causes fat cell to fat in vitro
Survival rate is low, so as to influence the effect of operation.Second is the continuation for being carried out using negative pressure fat suction machine operator's fat
After suction, the fat for disposably collecting sufficient amount, cleaning equipment is then recycled to oil droplet, muscle in fat blend after collection
Film, watery blood carry out purification separation, and this mode suction of fat speed is fast, but fat mixing during there is whole suction lipectomy
Thing has been at negative pressure state, and negative pressure is bigger, when the suction function time is longer, and the destruction to fat cell is bigger, causes
Fat cell survival rate is low, so as to influence the shortcoming of surgical effect；But also exist after fat acquisition, it is necessary to carry out subsequent purification
The complicated procedures of processing.The third is the pumping operation that fat is carried out using the internal negative pressure fat suction machine with negative pressure bottle,
Fat blend is pumped into after negative pressure bottle by negative pressure fat suction machine, and negative pressure bottle enters oil droplet, watery blood in fat blend after collection
Row purification separation, this mode there is also it is no solve fat for a long time in negative pressure state, fat cell survival rate is low asks
Lipochondrion, invisible watery blood, manadesma mixture after topic, and the simply standing finally obtained, also need follow-up handled.
When carrying out purified treatment to fat blend after collection, handled by centrifuge in current technology
Or cotton pad adsorption treatment, remove the watery blood in fat blend（Comprising invisible watery blood, invisible watery blood is referred to and fatty face
Color is approached, it is impossible to by visually differentiate, it is necessary to centrifuge or cotton pad adsorption conditionses under the watery blood that can just separate）Being obtained with oil droplet has
Imitate lipochondrion, centrifuge processing when need first fat blend is dispensed into centrifuge tube, then again centrifuge tube be put into from
Centrifugation is carried out in scheming and obtains lipochondrion, thus causes service speed slow, fat blend ingress of air overlong time, easily
It is contaminated, infects germ；And use artificial watery blood and oil droplet using in cotton pad absorbing fats mixture fast there is also operation
Degree is slow, and fat blend ingress of air overlong time is easily contaminated, infectd the shortcoming of germ.And both of which is present
It can not effectively go to take the shortcoming of manadesma in fat blend.
In current technology, when carrying out human body hypodermic injection filling, if not thorough containing separating in the lipochondrion injected
Manadesma, because of the blocking action of manadesma, injection can be caused to inject, and power is excessive, thus to the fat cell in syringe cause extruding
Damage；And if watery blood separation is not thorough in fat, again can be because of injection because contained watery blood, oil droplet amount are too high in lipochondrion
Effective lipochondrion it is very few, cause operation effect have a greatly reduced quality.
The content of the invention
In order to overcome prior art, will human body own fat collection, purification after be subcutaneously injected present in drawback,
Invention provides the negative pressure fat suction machine for having negative pressure bottle using existing inside as fat suction equipment, while suction of fat
Remove and extract intrafat visible watery blood and part oil droplet, with reference to associated mechanisms effect, obtain fat mixing after a certain amount of standing
It can be transferred in the absorbent packet with absorption cotton pad of no negative pressure in short time, turn in suction collection fat as far as possible after thing
Fat is moved to arrive without negative-pressure adsorption bag, prevent it is fatty for a long time because suction function and caused by cell survival rate reduce, into without negative pressure
The adsorption cotton that the invisible watery blood of remaining in fat blend in absorbent packet and oil droplet can be adsorbed built in bag is lined with effect and absorbed,
After the process of suction collection fat terminates, what is directly obtained in absorbent packet is effective lipochondrion and fraction of fascia tissue, after
Continuous filter effectively can filter manadesma in lipochondrion when being injected, so as to reach that liposuction speed is fast, fat cell is by negative
Press that action time short survival rate is high, contaminant filter effect is good in fat blend, Autologous fat granule to human body it is subcutaneous after can take
