Description

Technical Field

[0001] The utility model relates to the technical field of water light guns, in particular to a magnetic suction device, a handle and a push injection device for automatically identifying syringe specifications. Background Art

[0002] The water gun is a popular non-surgical injection beauty anti-aging technique. Through the magic anti-aging gun, water-light needles and other beauty liquids need to be injected with the help of the water-light gun as an injection device. When the existing injection device installs the water-light needle on the water-light gun, it is necessary to manually input the syringe specifications so that accurate injection can be performed. This method has certain safety hazards. Once the manual input is wrong, the injection volume will be deviated, affecting the safety of the person being injected. And every time the syringe is replaced, it is necessary to manually check the syringe specifications carefully and input them correctly, which is time-consuming and laborious.

[0003] For example, patent application CN218458470U discloses a device capable of automatically identifying syringe specifications, including a shell, a snap-on identification component is provided at the top of the shell, a water-light needle is provided at the top of the snap-on identification component, and an automatic injection component is provided inside the shell; in the snap-on identification component of the device, a resistor with a specific resistance value needs to be implanted on the syringe buckle of different specifications in the early stage, and the line connection between the resistor and the circuit board will be realized when snapping, so that the resistance value is identified by the circuit board detection circuit, so as to identify the syringe specification, and the detection of the resistor is a conventional technical means. In order to avoid excessive description of the document, no excessive description is made, and the syringe specification can be automatically identified, avoiding the link of manually inputting the syringe specification, avoiding the risk of manual input errors, ensuring the safety of the injector, and reducing the occurrence of medical accidents, saving time and effort, but in actual use, it is necessary to insert the automatic identification device into the slot and then perform the rotation docking operation. On the one hand, there are many operating steps, and on the other hand, if the rotation angle does not reach the specified angle, it is easy to cause the syringe to deviate and affect the final injection effect.

[0019] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0020] 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. 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.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a handle, the handle includes an upper shell 10 and a lower shell 11, the upper shell 10 and the lower shell 11 are detachably connected by bolts, the upper shell 10 and the lower shell 11 each have a cavity 12 inside, the bottom ends of the upper shell 10 and the lower shell 11 jointly form a plug-in chamber 13, the upper shell 10 and the lower shell 11 are detachably connected, which is convenient for early assembly and later maintenance. For installation and maintenance, only the bolts between the upper shell 10 and the lower shell 11 need to be removed to separate the upper shell 10 and the lower shell 11. At the same time, in order to ensure the sealing, a sealing strip can be installed between the upper shell 10 and the lower shell 11 to improve the sealing between the upper shell 10 and the lower shell 11, and the plug-in chamber 13 can be directly plugged into the syringe buckle 31.

[0022] An injection device, including a handle, and also including a driving motor 20 fixedly installed inside a mold cavity 12, a screw 21 is fixedly installed at the output end of the driving motor 20, an inner thread sleeve 22 is threadedly connected to the outer wall of the screw 21, an end of the screw 21 away from the driving motor 20 is rotatably connected to a lower shell 11 through a bearing, a slide 23 is fixedly installed on the side wall of the inner thread sleeve 22, a pusher 24 is fixedly installed on the side wall of the slide 23, and a slide groove and a slider slide are connected between the slide 23 and the upper shell 10 and the lower shell 11. Dynamic connection, when in use, start the drive motor 20, the drive motor 20 threadedly engages the screw rod 21, and the screw rod 21 threadedly engages the threaded sleeve 22. Since the threaded sleeve 22 is slidably connected to the upper shell 10 and the lower shell 11 through the slide seat 23, the threaded sleeve 22 can only slide horizontally and cannot rotate with the rotation of the screw rod 21. Therefore, when the threaded sleeve 22 rotates, the pusher 24 can be driven to move synchronously. The movement of the pusher 24 can directly push the syringe for injection, thereby realizing accurate quantitative injection, and the operation is convenient and safe.

[0023] Optionally, the inner wall of the pusher 24 is provided with a docking groove adapted to the injection needle. When in use, the syringe is clamped in the docking groove and can be used. The movement of the pusher 24 will drive the push handle of the syringe to move synchronously.

The negative pressure pipeline of the negative pressure needle 26 is installed through the handle and connected to an external control device. The bracket 25 can maintain the stability of the negative pressure needle 26. The negative pressure needle 26 can be directly replaced during disassembly and replacement. After the replacement is completed, the negative pressure needle 26 is inserted into the bracket 25, and then the negative pressure needle 26 is connected to the negative pressure pipeline for practical use.

A fixed value resistor 33, each resistor 33 represents a different model. After the insertion is completed, the resistor 33 can be detected by the chip in the handle (not shown in the figure), so as to be automatically identified. After insertion, a magnetic attraction force is generated between the magnetic body A30 and the magnetic body B32, so as to ensure that the syringe buckle 31 will not move up and down, so as to achieve the effect of quick installation and automatic identification. The material of the C-type buckle body 312 is plastic. The advantage of using plastic is that it can produce elastic deformation, so as to facilitate the syringe to be restrained on the inner wall of the C-type buckle body 312.
