Embodiment 1

[0029] Such as Figure 1-8 As shown, an autologous fat transplantation device for increasing the survival rate of fat cells includes a collection device, a processing device and an injection device. The collection device includes a fat collection device and a blood collection device. The fat collection device includes a fat removal support 1 and several liposuction chambers 2. There are several first sliding rails 3 on the liposuction bracket 1, and several first sliding blocks 31 are provided on the liposuction chamber 2. The liposuction chamber 2 can move on the first slide rail 3; the liposuction chamber 2 is provided with a piston 206, and the liposuction chamber 2 is divided into a working chamber 205 and a negative pressure chamber 207 by the piston 206, and one end of the negative pressure chamber 207 is provided with a negative pressure chamber. Pipeline 208, one end of the working chamber 205 is provided with a detachable needle 203, and the connection between the wor...

Embodiment 2

[0033] The difference between Example 2 and Example 1 is that the culture solution is an aqueous DMEM medium solution containing 15 mg / mL culture additive, the concentration of the aqueous DMEME medium solution is 5 mg / mL, and the culture additive includes the following parts by weight: Ingredients: 1 part baicalein, 5 parts choline chloride and 2.5 parts sorbitol.

Embodiment 3

[0035] The difference between Example 3 and Example 1 is that the culture solution is an aqueous DMEM medium solution containing 20 mg / mL culture additive, the concentration of the aqueous DMEME medium solution is 7.5 mg / mL, and the culture additive includes the following parts by weight: The number of ingredients: 3 parts of baicalein, 7.5 parts of choline chloride and 3 parts of sorbitol.

Abstract

The invention discloses an autologous fat transplantation device capable of increasing the fat cell survival rate. Multiple liposuction cavities and injection cavities are utilized for liposuction and injection steps, the positions of liposuction and fat injection in the human body are dispersed, and the problem of cutis laxa caused by over-concentrated liposuction position and the problem of low fat cell survival rate caused by over-concentrated fat injection position are prevented; the liposuction cavities and injection cavities are formed in a support by means of sliding blocks and sliding rails, needles of all liposuction cavities and injection cavities can be controlled to be in different working planes through limiting devices, and therefore the device conforms to the structure of the liposuction or injection part of the human body; in addition, fat cells and adipose-derived stem cells are separated from fat tissue which is taken out by means of a processing device, cultured respectively and then co-cultured, the adipose-derived stem cells are induced to be differentiated into capillaries in the fat cells, the survival rate of the fat cells is increased, and then the frequency of surgery is reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an autologous fat transplantation device for increasing the survival rate of fat cells. Background technique [0002] Autologous fat transplantation is to transplant the patient's own fat to the soft tissue defect, so that the recipient area can achieve the effect of plumping and shaping. Chinese patent CN103598901A discloses a fat transplantation device, which utilizes an integrated structure to filter and purify the extracted fat before directly implanting the fat. The activity of the fat will not be affected, and the pollution of the fat is also avoided; The fat is purified by the filter, and the purified fat is implanted into the human body with good compatibility. The structure is simple, the practicability is strong, and the industrialization is easy. [0003] But in actual work, we found that the fat survival rate after transplantation is low, generally 30% to 60%. The ke...
