Description

Technical Field

[0001] The utility model relates to the technical field of water light instruments, in particular to a tubular, precisely controllable, silent and lightweight water light instrument. Background Art

[0002] As people age and are exposed to the outside air for a long time, their facial skin will gradually become dull, loose, and have scars. The hydration device improves the skin by injecting hydration needles. The main ingredients of hydration needles are hyaluronic acid and collagen, which are administered by subcutaneous injection. After the injection, it can replenish the nutrients and moisture needed by the skin, while stimulating the regeneration of elastic fibers and collagen under the skin, nourishing subcutaneous cells, and quickly increasing the activity of subcutaneous cells. It can promote skin metabolism, remove some toxins in the skin, make the skin firm and tender, and play a role in reducing wrinkles, tightening the skin, and improving large pores.

[0003] Currently, all hyaluronic acid analyzers on the market are handheld, and use a DC screw motor to push the syringe for hyaluronic acid injection. The motor, screw, nut and other metal components in the handheld part are heavy and have a long structure. Holding the hand for a long time will cause wrist soreness and prone to tenosynovitis. At the same time, the motor makes a lot of noise when working at the face position, and the DC motor control has no brake and cannot stop accurately. The accuracy of the amount of liquid given each time is difficult to control, and there is a leakage problem after the accumulated error after multiple injections. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned prior art and provide a device which can reduce the weight and size of the handheld part of the water light instrument, reduce noise, and accurately control the amount of injected medicine.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a tubular, precisely controllable, silent, lightweight hyaluronic acid instrument, comprising a main unit, a hyaluronic acid needle, and a syringe. The syringe is installed in the main unit, and the hyaluronic acid needle and the syringe are connected through an infusion tube. A handle is installed at one end of the infusion tube close to the hyaluronic acid needle. An electric control component and a booster component are arranged in the main unit, and the booster component is connected to the piston rod of the syringe and is electrically connected to the electric control component.

[0006] Furthermore, the infusion tube is used to store all the liquid medicines, and the internal volume of the infusion tube is greater than the maximum infusion volume, and the volume is calculated by the tube diameter.

[0007] Furthermore, the booster assembly includes a motor, a syringe push plate and a screw, the screw is connected to the output end of the motor and is arranged parallel to the piston rod of the syringe, the syringe push plate is fixed to the piston rod of the syringe and is threadedly connected to the screw.

[0008] Furthermore, the motor is a closed-loop stepper motor, which has more precise start and stop control, thereby being able to accurately control the dosage.

[0009] Furthermore, the infusion tube is connected to the handle via a buckle.

[0010] The utility model is a tube-type, precisely controllable, silent and lightweight water light instrument, and its beneficial effects are:

[0011] 1. The consumables are changed from disposable syringes to disposable infusion tubes, which is cheaper;

[0012] 2. The DC motor drive in the original handheld part is removed and integrated into the host, which reduces the weight and size of the handle. The handle does not generate noise when working and works in a silent state.

[0013] 3. Adopt closed-loop stepper motor control, the motor start and stop control is precise, and the dosage of each medication can be accurately controlled;

[0014] 4. The handle has no power line connection, which is highly safe, more flexible and easy to control, and you won’t feel tired when holding it for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] As shown in the figure, a tube-type, precisely controllable, silent, lightweight water light instrument comprises a main unit 5, a water light needle 1, and a syringe 4. The syringe 4 is installed in the main unit 5. The water light needle 1 and the syringe 4 are connected through an infusion tube 3. The internal volume of the infusion tube 3 is greater than the maximum infusion volume of 5 ml. The infusion tube 3 is installed with a handle 2 at one end close to the water light needle 1. The infusion tube 3 is connected to the handle 2 by a buckle.

[0022] The host 5 is provided with an electric control component 9 and a booster component, and the booster component is connected to the piston rod 10 of the syringe 4 and is electrically connected to the electric control component 9. The booster component includes a motor 6, a syringe push plate 7 and a screw 8, and the screw 8 is connected to the output end of the motor 6 and arranged parallel to the piston rod 10 of the syringe 4. The syringe push plate 7 is fixed to the piston rod 10 of the syringe 4 and is threadedly connected to the screw 8.

[0023] The motor 6 can be a coreless motor, a servo motor, etc., but in order to accurately control the dosage, a closed-loop stepper motor is selected, and the motor start and stop control is more accurate.

[0024] Before injecting the prepared liquid medicine, the motor 6 is controlled by the electronic control component 9 to drive the screw 8 to drive the syringe push plate 7, and the piston rod of the syringe 4 is pulled to generate negative pressure, so that the prepared liquid medicine is drawn into the infusion tube 3. The internal volume of the infusion tube 3 is calculated to meet the maximum prepared liquid medicine volume, and the liquid medicine will not be drawn into the syringe 4. The syringe 4 is a reusable component. Conventional plastic syringes can be selected, which are discarded and replaced after multiple uses. Borosilicate glass syringes can also be selected, which are disinfected and cleaned after long-term use. Connect the infusion tube 3 to the water light needle 1, snap it into the handle 2, select the injection mode to start injecting the water light liquid medicine, and the electronic control component 9 will control the motor 6 in a closed loop according to the selected injection mode, drive the screw 8 to drive the syringe push plate 7, and push the piston rod of the syringe 4 to inject the prepared liquid medicine inside the infusion tube 3 from the water light needle 1 into the subcutaneous tissue in sequence.
