DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 The utility model discloses an adjustable injection device for extracting stem cells and fat, including a syringe 1, a piston body 18 movably installed in the syringe 1, and a connecting sleeve 12. The connecting sleeve 12 is detachably installed at one end of the syringe 1, and at least two latex tubes 10 are arranged on the outside of the connecting sleeve 12, a flow control valve 11 is installed on the latex tube 10, and a needle assembly is arranged at the other end of the latex tube 10.

[0023] This embodiment realizes synchronous extraction at multiple positions in a region by setting up multiple needle assemblies. With the setting of the latex tube 10, the position of the needle assembly can be easily adjusted, thereby improving the practicability of the device. With the setting of the flow control valve 11, the flow inside each latex tube 10 can be individually controlled, thereby facilitating the control of the extraction or injection of fat at different positions in a single region, making it convenient for medical staff to conduct overall observation of a single region, thereby achieving a better cosmetic effect.

[0024] Furthermore, the adjustable stem cell and fat extraction injection device provided in this embodiment also includes a fixing component, which is arranged on the outside of the syringe 1 to fix the needle component to avoid unnecessary needle components causing harm to the user and improve the safety of the device.

[0025] like Figure 2-Figure 3As shown, the needle assembly includes a needle plug 13 installed at the other end of the latex tube 10, a needle holding handle 14 is provided on one side of the needle plug 13, and a needle 15 is installed on the other end of the needle plug 13. The needle 15 is a component made of stainless steel. The setting of the needle holding handle 14 makes it convenient for the user to hold the needle 15, so that the needle 15 can be inserted from different directions, which is convenient for the user to operate.

[0026] like Figure 1-Figure 4 As shown, the above-mentioned fixing component includes a needle cap 7 fixed to the outside of the syringe 1. The number of needle caps 7 is the same as the number of needles 15 for protecting the needles 15. A notch groove 17 adapted to the needle holding handle 14 is provided at the lower end of the outer side of the needle cap 7. The engagement between the notch groove 17 and the needle holding handle 14 facilitates the positioning, storage and use of the needle 15.

[0027] like Figure 2 and Figure 3 As shown, in order to achieve the fixation of the needle 15, rubber rings are evenly arranged on the outer surface of the needle bolt 13, and the outer surface of the rubber ring abuts against the inner wall of the needle cap 7. When the needle bolt 13 is inserted into the needle cap 7, the rubber ring abuts against the inner wall of the needle cap 7 to increase the friction force at the connection between the needle bolt 13 and the needle cap 7, thereby improving the stability of the needle bolt 13 when it is fixed, which is further beneficial to the fixation of the needle 15.

[0028] like Figure 1 and Figure 2 As shown, in order to further improve the fixing effect of the latex tube 10 and avoid the redundancy of the latex tube 10, a limiting ring 8 is fixed on the outer side of the syringe 1 at one end close to the connecting sleeve 12, and a limiting groove 9 adapted to the latex tube 10 is opened on the limiting ring 8, and the inner diameter of the limiting groove 9 is smaller than the outer diameter of the latex tube 10. The latex tube 10 is embedded in the limiting groove 9, which can improve the orderliness of the latex tube 10 when it is stored.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, in order to realize the extraction and injection of the present device, a top cover 4 is threadedly connected to the end of the syringe 1 away from the connecting sleeve 12, and a piston shaft 5 fixedly connected to the piston body 18 is installed inside the syringe 1. One end of the piston shaft 5 passes through the top cover 4 and is installed with a piston handle 6. The piston handle 6 is pressed or pulled so that the piston shaft 5 drives the piston body 18 to move inside the syringe 1, thereby realizing the extraction and injection of the syringe 1.

[0030] like Figure 3 and Figure 4As shown, in order to achieve the installation of the latex tube 10, a suction tube 19 is provided at one end of the syringe 1 close to the connecting sleeve 12, and through holes 20 are evenly opened on the surface of the suction tube 19, and a connecting sleeve 21 is fixedly provided at one end of the suction tube 19 close to the syringe 1. The connecting sleeve 12 is sleeved on the outside of the suction tube 19 and is threadedly connected with the connecting sleeve 21. The threaded connection between the connecting sleeve 21 and the connecting sleeve 12 facilitates the disassembly and replacement of the connecting sleeve 12, thereby improving the practicability of the equipment.

[0031] like Figure 1 and Figure 2 As shown, in order to facilitate the observation of the amount of fat or stem cells inside the syringe 1, scale lines 2 are provided on the surface of the syringe 1 along its axial direction, and a partition 3 is fixed to the end of the syringe 1 away from the connecting sleeve 12, and the partition 3 is fixed to the needle cap 7 to facilitate the fixation of the needle cap 7.

[0032] Furthermore, in order to avoid excessive or insufficient stock inside the syringe 1, an output tube is installed on the outside of the syringe 1 near the connecting sleeve 12, and a rubber cap 16 is installed on the output tube. The rubber cap 16 is pierced by an external needle tube to extract fat from the syringe 1 or input fat into the syringe 1, thereby improving the practicability of the device.

[0033] The working principle and use process of the utility model are as follows: when in use, the needle 15 is taken out from the inside of the needle cap 7 through the needle holding handle 14, and the needle 15 is inserted into the designated area of ​​the user. Through the arrangement of multiple needles 15 and latex tubes 10, the simultaneous extraction or injection of fat at multiple positions in the area is realized. Under the arrangement of the latex tubes 10, the adjustment of the position of the needle assembly is convenient, and the practicality of the equipment is improved. Under the arrangement of the flow control valve 11, the flow inside each latex tube 10 can be individually controlled, which is then conducive to controlling the extraction or injection of fat at different positions in a single area, and is convenient for medical staff to observe a single area as a whole, so that the cosmetic effect is better. The piston handle 6 is pressed or pulled so that the piston shaft 5 drives the piston body 18 to move inside the syringe 1, thereby realizing the extraction and injection of the syringe 1, avoiding multiple operations of the piston shaft 5 by medical staff, and being conducive to the user completing fat extraction or injection at one time, thereby improving the practicality of the equipment.
