Description

Technical Field

[0001] The utility model relates to the technical field of water light syringes, and more specifically to a sterile medical water light syringe. Background Art

[0002] The water light injector is a device used for skin beauty treatment. It can inject water light agent into the skin layer through the injector, so as to remove spots, pores, sagging skin and other problems on the skin and achieve beauty effects.

[0003] Chinese Patent Authorization Announcement No.: CN215995281U provides an eye and face water light revitalizing injection, which makes the oblique incision fit the face to control the injection angle, making the entire manual water light injection process more convenient and ensuring the quality and effect of the manual water light injection. However, at present, the water light agent in a single syringe needs to be injected into different parts of the user's face respectively, and medical staff need to perform multiple injections, which is a large workload. It may cause the medical staff to inject the water light dose each time without being accurate enough, resulting in the problem of a single injection dose being larger or smaller, thereby reducing the therapeutic effect of the water light agent.

[0004] Therefore, a sterile medical hydro-injector is proposed in view of the above problems. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a sterile medical hydro-injector, which can insert the hydro-injection needle into the user's skin, and then the medical staff pushes the piston rod. When the piston rod moves one end distance, the limit block is stuck in the adjacent limit groove by the elastic force of the telescopic spring. At this time, the hydro-injection needle can be separated from the user's skin and inserted into another part of the user. Then the medical staff squeezes the arc sleeve to make the limit block away from the limit groove, releases the limit of the square rod, and repeats the above operation. It can accurately control the injection dose each time to be equal, reduce the probability of a single injection dose being larger or smaller, and thus improve the therapeutic effect of the hydro-injection agent.

[0026] Example:

[0027] See also Figure 1 A sterile medical hydro-injection syringe comprises a hydro-injection syringe 1, one end of which is fixedly connected to a hydro-injection needle 7, and a piston rod 2 is slidably connected inside the hydro-injection syringe 1, one end of the piston rod 2 is fixedly connected to a push plate 3, and a pair of square rods 4 are installed on the push plate 3 near one end of the hydro-injection syringe 1, and a pair of positioning components 6 are provided at the outer end of the hydro-injection syringe 1. By inserting the hydro-injection needle 7 into the user's skin and pushing the push plate 3, the piston rod 2 is controlled to move inside the hydro-injection syringe 1, thereby injecting the hydro-injection agent inside the hydro-injection syringe 1 into the user's skin.

[0028] See also Figure 2 The positioning assembly 6 includes a connecting plate 61, which is fixed to the outer end of the hyaluronic acid injection syringe 1. The connecting plate 61 and the square rod 4 are detachable structures. The connecting plate 61 and the square rod 4 are respectively fixed to the hyaluronic acid injection syringe 1 and the push plate 3 by screws, and can be disinfected for next use. The hyaluronic acid injection syringe 1, the piston rod 2, and the hyaluronic acid injection needle 7 are disposable and will be discarded after use. A through hole 62 is opened inside the connecting plate 61, and the square rod 4 passes through the through hole 62.

[0029] The positioning assembly 6 also includes an arc-shaped sleeve 65. Medical staff can place two fingers on the inner wall of a pair of arc-shaped sleeves 65 to facilitate the use of the syringe. The outer end of the arc-shaped sleeve 65 is fixedly connected to a slider 64. The bottom end of the connecting plate 61 is provided with a slide groove 63. The slider 64 is slidably connected to the slide groove 63, which can limit the movement trajectory of the arc-shaped sleeve 65 and enable it to move stably.

[0030] See also Figure 3 The outer end of the square rod 4 is provided with a plurality of equidistantly arranged limit grooves 5. Since the plurality of limit grooves 5 are equidistantly arranged, each time the limit block 66 is inserted into the limit groove 5, the injection to the same part is stopped, thereby accurately controlling the dose of each injection to be equal. Moreover, the dose of a single injection can be controlled by replacing the square rod 4, and the dose of a single injection can be adjusted by changing the distance between two adjacent limit grooves 5. A spring groove 67 connected to the through hole 62 is provided inside the connecting plate 61, and a telescopic spring 68 is installed on the inner wall of the spring groove 67. A limit block 66 matching the limit groove 5 is fixedly connected to one end of the telescopic spring 68. Under the elastic force of the spring groove 67, the limit block 66 can be inserted into the limit groove 5, thereby fixing the square rod 4 and limiting the position of the piston rod 2.

[0031] The outer end of the limit block 66 is fixedly connected to a connecting rope 69, and the end of the connecting rope 69 away from the limit block 66 is fixedly connected to the slider 64. The inner rotation of the connecting plate 61 is connected to a guide roller 610, and the outer end of the guide roller 610 abuts against the connecting rope 69, which can change the direction of the force, so that the water-light injection needle 7 can be inserted into the user's skin. Then the medical staff pushes the piston rod 2. When the piston rod 2 moves one end distance, the limit block 66 is clamped into the adjacent limit groove 5 by the elastic force of the telescopic spring 68. At this time, the water-light injection needle 7 can be separated from the user's skin and inserted into another part of the user. The medical staff controls the two fingers to move closer to each other, squeezes the arc sleeve 65, drives the slider 64 to move inside the slide groove 63, and under the action of the connecting rope 69, the limit block 66 is moved away from the limit groove 5, thereby releasing the limit of the square rod 4. Repeating the above operation can accurately control the injection dose to be equal each time, reduce the probability of a single injection dose being larger or smaller, and thus improve the therapeutic effect of the water-light agent.

[0032] The outer end of the limit block 66 is rotatably connected to a ball, which abuts against the inner wall of the limit groove 5. When the piston rod 2 is pushed, the ball at the outer end of the limit block 66 can contact and rotate with the outer end of the square rod 4, reducing the wear of the limit block 66.

[0033] Working principle: the medical staff can place two fingers on the inner wall of a pair of arc-shaped sleeves 65 and the thumb on the push plate 3 to hold the syringe, and then insert the water-light injection needle 7 into the part of the user that needs beauty treatment. Then the medical staff controls the two fingers to move closer to each other, squeezes the arc-shaped sleeve 65, drives the slider 64 to move inside the slide groove 63, and under the action of the connecting rope 69, the limit block 66 is moved away from the limit groove 5. Then the medical staff slowly pushes the piston rod 2 for a distance with the thumb, ends squeezing the arc-shaped sleeve 65, and injects the water-light agent inside the water-light injection syringe 1 into the user's skin. When the piston rod 2 moves to a certain distance, the limit block 66 is stuck in the adjacent limit groove 5 by the elastic force of the telescopic spring 68. When the medical staff cannot push the piston rod 2 again, the water-light injection needle 7 can be separated from the user's skin and inserted into another part. The above operation is continued to perform large-area water-light injection on the user.

[0034] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
