Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic syringes, in particular to an anti-embolism facial cosmetic injection device. Background Art

[0002] Plastic surgery is also known as reconstructive surgery or plastic surgery. Its treatment scope mainly covers injuries and diseases of skin, muscle and bone, as well as congenital or acquired defects and deformities of tissues or organs. Treatment includes two aspects: repair and reconstruction. Various tissues of the font are transplanted by surgical methods. Allogeneic, heterogeneous tissues or tissue substitutes can also be used to repair tissue defects or deformities caused by various reasons, so as to improve or restore physiological functions and appearance.

[0003] However, during the process of injecting drugs into the face, if the operation is improper and a larger blood vessel is punctured, it is easy to cause vascular embolism. If the operator does not discover it in time, it is easy to cause a medical accident. In addition, the injection method is mostly manual, and the amount of injected liquid cannot be accurately controlled, resulting in the failure to achieve the best cosmetic effect. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-embolism facial beauty injection device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses an anti-embolism facial beauty injection device, comprising a syringe and a limiting assembly, wherein a piston rod is arranged inside the syringe, an injection piston is arranged at one end of the piston rod, the injection piston is arranged inside the syringe and slidably cooperates with the syringe, an injection needle is installed at one end of the syringe, an observation chamber is installed on the outer side of the syringe near one end of the injection needle, the other end of the piston rod is fixedly connected with a push plate, the push plate is arranged on the outer side of the syringe, a return blood vessel is arranged inside the injection needle, one end of the return blood vessel is arranged in the observation chamber and communicated with the observation chamber.

[0007] The observation room is made of a transparent plate.

[0008] The limiting assembly includes an arc-shaped splint and a hinge shaft. There are two groups of arc-shaped splints, and the two groups of arc-shaped splints are arranged on the circumferential side of the syringe and are clamped with the syringe. The hinge shaft is arranged between the two groups of arc-shaped splints and is hinged with them. One end of the two groups of arc-shaped splints is fixedly connected to a connecting plate, and a compression spring is installed between the two groups of connecting plates.

[0009] The surfaces of the two groups of arc-shaped clamping plates are fixedly connected to the limiting thread blocks, and the inner parts of the limiting thread blocks are spirally connected to the limiting screw rods.

[0010] One end of the limiting screw is arranged on one side of the push plate.

[0011] The side surface of the syringe is provided with scale lines.

[0012] The utility model has the following beneficial effects:

[0013] The utility model provides an injection needle, an observation chamber and a return blood vessel. When the needle tip punctures the blood vessel, the blood in the blood vessel will quickly enter the return blood vessel along the needle tip under the push of blood pressure. Since the inner diameter of the return blood vessel is very small, the returning blood rises very quickly. The returning blood enters the observation chamber through the return blood vessel, so that medical staff can find the returning blood in time and perform subsequent operations. By providing a limit assembly, the position of the arc splint on the syringe can be adjusted according to the required injection volume, and then the position of the limit screw can be adjusted according to the scale line. Then, when the push plate pushes the piston rod to move in the syringe, when the required injection volume is reached, the push plate is resisted by the limit screw so that it cannot be pushed, thereby realizing the control of the injection volume and achieving the best cosmetic effect.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1-Figure 5 As shown, the utility model is an anti-embolism facial beauty injection device, comprising a syringe 1 and a limiting assembly 2, a piston rod 105 is arranged inside the syringe 1, an injection piston 106 is arranged at one end of the piston rod 105, the injection piston 106 is arranged inside the syringe 1 and slidably cooperates with the syringe, an injection needle 102 is installed at one end of the syringe 1, an observation chamber 103 is installed on the outer side of the syringe 1 close to one end of the injection needle 102, the other end of the piston rod 105 is fixedly connected to a push plate 101, the push plate 101 is arranged on the outer side of the syringe 1, a return blood vessel 107 is arranged inside the injection needle 102, one end of the return blood vessel 107 is arranged in the observation chamber 103 and communicated with the observation chamber 103.

[0027] The observation chamber 103 is made of a transparent plate.

[0028] The limiting assembly 2 includes an arc-shaped splint 201 and a hinge shaft 203. There are two groups of arc-shaped splints 201, and the two groups of arc-shaped splints 201 are arranged on the circumferential side of the syringe 1 and are snap-fitted with the syringe 1. The hinge shaft 203 is arranged between the two groups of arc-shaped splints 201 and is hingedly fitted therewith. One end of the two groups of arc-shaped splints 201 is fixedly connected with a connecting plate 202, and a compression spring 204 is installed between the two groups of connecting plates 202.

[0029] The surfaces of the two sets of arc-shaped clamping plates 201 are fixedly connected to the limiting thread blocks 205 , and the inner part of the limiting thread blocks 205 is spirally connected to the limiting screw rod 206 .

[0030] One end of the limiting screw 206 is disposed on one side of the push plate 101 .

[0031] Scale lines 104 are provided on the circumferential side of the syringe 1 .

[0032] It should be noted that, in actual use, the position of the arc splint 201 on the syringe 1 is first adjusted according to the required amount of liquid to be injected, and then the position of the limit screw 206 is adjusted according to the scale line 104.
