Description

Technical Field

[0001] This invention relates to the field of electronic injector technology, specifically to an anti-backflow structure for an electronic injector booster device. Background Technology

[0002] Currently, most hyaluronic acid injections on the market use a booster device in conjunction with a syringe and needle. The basic principle of the booster device is as follows: a negative pressure pump generates suction, allowing the bottom shell of the hyaluronic acid needle to adhere to the skin in the area to be injected, producing a certain lifting effect. At the same time, sensors inside the booster device detect changes in airflow and transmit them to the control unit, which then issues the corresponding injection command.

[0003] The use of a booster device in conjunction with a syringe and needle greatly improves the efficiency of doctors' operations and the injection effect for users of mesotherapy. However, this injection method has obvious hidden dangers. It is difficult for the injected drug to be completely absorbed by the user's skin during the injection process. Some of the drug may be affected by the suction of the booster device's negative pressure and enter the booster device's main unit through the negative pressure air passage. With long-term use or excessive single injection volume, the air passage of the booster device is prone to blockage, corrosion of the internal electronic components of the booster device, and abnormal circuit short circuits, which will have a great impact on the injection effect, the lifespan of the booster device, and injection safety.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop an anti-backflow structure for an electronic injector booster device. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-backflow structure for an electronic injector booster device to solve the problems mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-backflow structure for an electronic injector booster device, comprising a body, a bottom shell on the body, an anti-backflow mechanism inside the bottom shell, the anti-backflow mechanism comprising a negative pressure pump disposed inside the bottom shell, a negative pressure pump inlet pipe at the air inlet end of the negative pressure pump, and a built-in liquid accumulation component at one end of the negative pressure pump inlet pipe;

[0007] The built-in liquid accumulation component consists of a built-in air tube seat and a built-in liquid accumulation bottle located below the built-in air tube seat. The built-in air tube seat is provided with an air outlet and an air inlet. The negative pressure pump inlet pipe is connected to the air outlet of the built-in air tube. An internal negative pressure pipe is inserted into the air inlet of the built-in air tube. An instrument negative pressure interface is embedded in the outer wall of the bottom shell. A negative pressure inlet pipe is provided on the instrument negative pressure interface. An external liquid accumulation component is provided at one end of the negative pressure inlet pipe.

[0008] The external fluid collection component consists of an external air tube seat and an external fluid collection bottle located below the external air tube seat. The external air tube seat is provided with an external air tube outlet and an external air tube inlet. The external air tube outlet is connected to a negative pressure inlet pipe. The external air tube inlet is provided with an external negative pressure pipe, and one end of the external negative pressure pipe is provided with a syringe.

[0009] Preferably, a cover is provided on the top of the bottom shell, a slot is provided at the edge of the bottom shell, and a positioning post is provided at the inner corner of the bottom shell. The slot and the positioning post are connected to the cover.

[0010] Preferably, the external liquid accumulation component is provided with a mounting bracket, which is concave in shape and is connected to the external liquid accumulation component and the bottom shell by bolts.

[0011] Preferably, the bottom of the machine body is provided with multiple casters, the front of the machine body is provided with a storage box, the side of the machine body is provided with a bracket, the bracket is connected to the machine body by bolts, and the bracket cooperates with the syringe.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention relates to an anti-backflow structure for an electronic injector booster device. The anti-backflow mechanism ensures that when the syringe travels along the gas path of the electronic injector booster device, the syringe first accumulates in an external liquid collection bottle. This external liquid collection bottle is easily visible to the operator and can be conveniently emptied at any time, eliminating the possibility of the syringe entering the main unit of the electronic injector booster device in most cases. However, in extreme situations such as failure to clean the external liquid collection bottle in time or a particularly viscous syringe, a small amount of syringe may enter the main unit along the gas path. In this case, the internal liquid collection bottle acts as a secondary accumulation point. The operator only needs to maintain the internal liquid collection bottle at fixed intervals to ensure that the syringe does not affect the normal gas path, contaminate the internal electronic components, or cause short circuits, greatly extending the service life of components and improving safety.

[0014] This invention relates to an anti-backflow structure for an electronic injector booster device. The cover and bottom shell are assembled in a detachable manner, which facilitates the operator to regularly clean the built-in liquid bottle inside the bottom shell. The bracket, storage box, and casters provided make it convenient for the operator to use the device, thereby improving the practicality of the equipment. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification. Example

[0020] Please see Figure 1 and Figure 2 As shown, the present invention provides a backflow prevention structure technical solution for an electronic injector booster device: it includes a body 1, a bottom shell 14 on the body 1, and an anti-backflow mechanism inside the bottom shell 14. The anti-backflow mechanism includes a negative pressure pump 31 installed inside the bottom shell 14. The air inlet end of the negative pressure pump 31 is provided with a negative pressure pump air inlet pipe 32. Specifically, the interface between the negative pressure pump air inlet pipe 32 and the negative pressure pump 31 is sealed. One end of the negative pressure pump air inlet pipe 32 is provided with a built-in liquid accumulation component. Specifically, the built-in liquid accumulation component is used for secondary accumulation to ensure that the injection will not affect the normal air path, nor will it contaminate the internal electronic components of the main unit or cause short circuit abnormalities.

[0021] The built-in liquid accumulation component consists of a built-in trachea seat 33 and a built-in liquid accumulation bottle 34 located below the built-in trachea seat 33. The built-in trachea seat 33 is provided with a built-in trachea outlet end 331 and a built-in trachea inlet end 332. The negative pressure pump inlet pipe 32 is connected to the built-in trachea outlet end 331. Specifically, the interface between the negative pressure pump 32 and the built-in trachea outlet end 331 is sealed. An internal negative pressure pipe 35 is inserted into the built-in trachea inlet end 332. Specifically, the interface between the built-in trachea inlet end 332 and the internal negative pressure pipe 35 is sealed. An instrument negative pressure interface 16 is embedded on the outer wall of the bottom shell 14. A negative pressure inlet pipe 36 is provided on the instrument negative pressure interface 16. One end of the negative pressure inlet pipe 36 is provided with an external liquid accumulation component. Specifically, the needle inside the external liquid accumulation component is easy for the operator to find and can be easily emptied at any time, eliminating the possibility of the needle entering the main unit of the electronic injector control booster device in most cases.

[0022] The external effusion assembly consists of an external trachea seat 37 and an external effusion bottle 371 located below the external trachea seat 37. The external trachea seat 37 is provided with an external trachea outlet end 372 and an external trachea inlet end 373. The external trachea outlet end 372 is connected to the negative pressure inlet pipe 36. Specifically, the interface is sealed. The external trachea inlet end 373 is provided with an external negative pressure pipe 39. One end of the external negative pressure pipe 39 is provided with a syringe 2.

[0023] In this embodiment, the injection is injected into the external collection bottle 371. The injection accumulated in the external collection bottle 371 is easily visible to the operator and can be emptied at any time. This eliminates the possibility of the injection entering the main unit of the electronic injector control booster device in most cases. The negative pressure pump 31 is turned on and operates, which generates negative pressure in the negative pressure pump inlet pipe 32 and acts on the air passage connected to it until the drug is injected into the syringe 2 through the external negative pressure pipe 39 and injected by the syringe 2.

[0024] If the operator fails to clean the external liquid collection bottle 371 in time for some reason, or if the injection is particularly viscous, a small amount of injection may enter the main unit through the gas pipeline. At this time, the internal liquid collection bottle 34 will play a secondary accumulation role. The operator only needs to maintain the internal liquid collection bottle at a fixed period to ensure that the injection will not affect the normal gas pipeline, nor will it contaminate the internal electronic components of the main unit or cause short circuit abnormalities.

[0025] Please see Figure 2 As shown, a cover 15 is provided above the bottom shell 14, a slot 141 is provided at the edge of the bottom shell 14, and a positioning post 142 is provided at the inner corner of the bottom shell 14. The slot 141 and the positioning post 142 are connected to the cover 15. Specifically, the cover 15 and the bottom shell 14 are detachably connected.

[0026] In this embodiment, since the cover 15 and the bottom shell 14 are detachably connected, it is convenient for the operator to clean the liquid in the built-in liquid collection bottle 34 regularly. The built-in liquid collection bottle 34 is used for secondary accumulation to ensure that the injection will not affect the normal gas path, nor will it contaminate the internal electronic components of the main unit or cause short circuit abnormalities.

[0027] Please see Figure 1 and Figure 2 As shown, the external liquid accumulation assembly is further provided with a mounting bracket 38, which is concave in shape and is connected to the external liquid accumulation assembly and the bottom shell 14 by bolts.

[0028] In this embodiment, the mounting bracket 38 facilitates the assembly of external liquid accumulation components.

[0029] Please see Figure 1 As shown, furthermore, the bottom of the body 1 is provided with multiple casters 13. Specifically, multiple casters 13 are provided. The front of the body 1 is provided with a storage box 11, and the side of the body 1 is provided with a bracket 12. The bracket 12 is connected to the body 1 by bolts and cooperates with the syringe 2.

[0030] In this embodiment, the caster wheel 13 facilitates the movement of the machine body 1, the storage box 11 facilitates the operator to place instruments and equipment, improving practicality, and the bracket 12 facilitates the placement of the syringe 2.

[0031] Specifically, the working principle and usage process of this invention are as follows: The injection is injected into the external liquid collection bottle 371. The injection accumulated in the external liquid collection bottle 371 is easily discovered by the operator and can be emptied at any time. This eliminates the possibility of the injection entering the main unit of the electronic injector control booster device in most cases. The negative pressure pump 31 is turned on. The negative pressure pump 31 operates, which generates negative pressure in the negative pressure pump air inlet pipe 32 and acts on the air passage pipe connected to it until the medicine is injected into the syringe 2 through the external negative pressure pipe 39 and injected by the syringe 2.

[0032] If the operator fails to clean the external liquid collection bottle 371 in time for some reason, or if the injection is particularly viscous, a small amount of injection may enter the main unit through the gas pipeline. At this time, the internal liquid collection bottle 34 will play a secondary accumulation role. The operator only needs to maintain the internal liquid collection bottle at a fixed period to ensure that the injection will not affect the normal gas pipeline, nor will it contaminate the internal electronic components of the main unit or cause short circuit abnormalities, until the entire work sequence is completed.
