Description

Technical Field

[0001] The present invention relates to the technical field of beauty instruments, and in particular to a non-invasive beauty instrument and a use method thereof. Background Art

[0002] A mesotherapy device is a beauty instrument that uses modern technology to change skin condition or solve specific skin problems. Beauty instruments can be divided into ultra-micro-penetration mesotherapy devices, mesotherapy devices and needle-free mesotherapy devices (poreless mesotherapy devices) according to their working principles and application scenarios. Each mesotherapy device has its own unique advantages and technical characteristics.

[0003] In the existing hole-free mesotherapy instrument, a gas cylinder is provided to eject the high-pressure gas in the gas cylinder and assist the drug solution to enter the human skin, thereby breaking through the barrier of the skin surface and injecting nutrients or drugs into the subcutaneous tissue without using needles and electricity. However, the gas cylinder of the mesotherapy instrument is installed inside the instrument. When the gas cylinder is used up and needs to be replaced, various parts need to be disassembled before the gas cylinder can be taken out. Conversely, when installing the gas cylinder, other parts also need to be involved. Therefore, this process is relatively complicated, which not only wastes the time of the user, but also reduces the work efficiency of the user. Summary of the invention

[0038] The water absorbing member is fixedly connected to the outer shell and is located in the buffer cover.

[0039] As a further preferred solution, a method for using a non-invasive mesotherapy device is provided. Based on the above-mentioned non-invasive mesotherapy device, the method for using the non-invasive mesotherapy device is as follows:

[0040] Step 1: Place the syringe on the mounting plate, and put the gas cylinder into the mounting cylinder, then fix the push cylinder on the mounting cylinder, and the push rod is in contact with the gas cylinder;

[0041] Step 2: After the push rod contacts the gas cylinder, the installation cylinder is inserted into the support sleeve until the mouth of the gas cylinder contacts the support sleeve, and the movement of the installation cylinder is stopped. During this process, the installation cylinder squeezes the limit plate and the first elastic member is compressed;

[0042] Step 3: After stopping the movement of the installation cylinder, press the push rod, the push rod pushes the gas cylinder, and the gas cylinder pumps high-pressure gas into the gas storage chamber;

[0043] Step 4: The pressure in the gas storage chamber increases, the detection plate moves and pushes the hydraulic oil, so that the hydraulic oil drives the positioning block to move, and the positioning block is inserted into the upper limit hole of the installation tube and contacts one side of the gas cylinder. At this time, the positioning block limits the installation tube and the gas cylinder, and the gas cylinder is in the exhaust state;

[0044] Step 5: After the gas storage cavity is filled with high-pressure gas, the high-pressure gas in the gas storage cavity and the liquid in the syringe enter the needle together and are discharged from the needle to the skin;

[0045] Step 6: After the gas pressure in the gas cylinder decreases, the sensor also detects that the pressure in the gas storage chamber decreases, and the sensor controls the driving member to reduce the moving speed of the push plate;

[0046] Step 7: When the gas pressure in the gas cylinder is insufficient, the detection board is reset, and the positioning block releases the limit of the installation tube and the gas cylinder;

[0047] Step 8: The gas cylinder and the mounting tube are reset under the action of the first elastic member, and the gas cylinder and the mounting tube are taken out and replaced.

[0048] The beneficial effects of the present invention are as follows: the present invention threadably connects the installation tube and the support sleeve, so that the installation tube carries the gas cylinder into the support sleeve. At the same time, the installation tube is not completely placed in the support sleeve. When taking out the gas cylinder, it can be taken out by simply pulling the installation tube, thereby facilitating the installation and disassembly of the installation tube and the gas cylinder and improving the work efficiency of the user.

[0049] The present invention enables the gas cylinder carried by the installation tube to be automatically ejected through the pushing action of the first elastic member, thereby further reducing the workload of the user and thus improving the work efficiency of the user.

[0050] The present invention provides a pressure relief chamber in the support sleeve to buffer the high-pressure gas in the gas storage chamber, thereby preventing the high-pressure gas in the gas storage chamber from quickly pushing out the gas cylinder and causing damage to the user. At the same time, since the installation method of the installation tube is threaded, the thread can also prevent it from being quickly ejected.

[0051] The present invention limits the mounting tube and the gas cylinder by means of a positioning block, so that the gas cylinder is always in an inflated state, and at the same time improves the stability of the mounting tube and the gas cylinder during use, thereby preventing the gas cylinder from shaking, causing the bottle mouth to lose contact with the support sleeve, and further preventing the gas in the gas cylinder from entering the gas storage cavity.

[0052] The present invention detects the pressure in the gas storage cavity in real time through a sensor, and controls the moving speed of the push plate, thereby controlling the medicine discharge speed of the syringe, so that the gas discharge amount and the medicine liquid discharge amount are in a certain proportion, thereby improving the utilization rate of the medicine liquid and reducing the waste of the medicine liquid.

DETAILED DESCRIPTION

[0066] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as "setting" and "installation" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] Example 1: A non-invasive mesotherapy instrument, please refer to Figure 1-Figure 6, including: a shell 1, in which a support sleeve 2 is fixedly connected; a mounting tube 3, which is threadedly connected to the support sleeve 2, in which a gas storage chamber 201 is arranged, and a needle 4 is installed on the shell 1, and the needle 4 is connected to the gas storage chamber 201; a mounting plate 5, which is fixed to the shell 1, and a syringe 6 is installed on the mounting plate 5, and the syringe 6 is connected to the needle 4; a gas cylinder 7, which is installed in the mounting tube 3, and the gas cylinder 7 is connected and cooperated with the gas storage chamber 201, and the high-pressure gas in the gas cylinder 7 is used to push the medicine liquid to assist the medicine liquid to enter the body; a reset component, which is arranged in the support sleeve 2, and is used to push the gas cylinder 7 to pop out of the mounting tube 3; a trigger component, which is arranged on the mounting tube 3, and is used to push the gas cylinder 7 to move and eject the high-pressure gas therein.

[0068] It is worth mentioning that the shape of the shell 1 is L-shaped, which is convenient for users to hold and operate; a number of support plates are fixedly connected to the inner wall of the shell 1, and the support plates are used to fix the support sleeve 2. The upper side of the shell 1 is hinged with a cover plate, which can be opened to facilitate the replacement of the syringe 6. At the same time, the cover plate is made of a transparent material (such as an acrylic plate, but not limited to this); the gas storage cavity 201 is used to hold the gas discharged from the gas cylinder 7, which is convenient for detecting the content in the gas cylinder 7; the needle 4 is an existing structure, and an electric control valve is arranged inside it, and the electric control valve is located on the side of the needle 4 close to the gas storage cavity 201, and the electric control valve is used to control the discharge of the high-pressure gas in the gas storage cavity 201; the syringe 6 is an existing drug syringe, and is filled with liquid medicine; in the present invention, In the embodiment, the syringe 6 performs injection through the existing driving device, and an electric control button is arranged on the left side of the shell 1, through which the discharge of the gas in the gas cylinder 7 and the discharge of the medicine in the syringe 6 are controlled (that is, the driving device of the syringe 6 and the electric control valve in the needle 4 are electrically connected to the electric control button), which is convenient for users to operate; two symmetrical bosses are arranged on one side of the mounting cylinder 3, and symmetrical threaded grooves are arranged on the inner wall of the support sleeve 2, and the inclination angle of the threaded groove is greater than 45°, so as to facilitate the installation and replacement of the mounting cylinder 3, and the double thread can improve the stability of the mounting cylinder 3; the bottle mouth structure principle of the gas cylinder 7 is similar to that of a cassette furnace gas tank, and this mechanism can discharge the gas inside by pressing the air outlet pipe of the bottle mouth.

[0069] The working principle of the above scheme is as follows: when using the device, the user first places the syringe 6 on the mounting plate 5, and connects the piston rod of the syringe 6 to the driving device, then places the gas cylinder 7 into the mounting tube 3, and fixes the gas cylinder 7 and the mounting tube 3 as a whole through the trigger assembly. Thereafter, the mounting tube 3 is rotated into the support sleeve 2, and the convex column on the mounting tube 3 moves along the threaded groove of the support sleeve 2. When the bottle mouth of the gas cylinder 7 contacts the support sleeve 2, the mounting tube 3 contacts the reset assembly and makes the reset assembly work. At this time, the rotation of the mounting tube 3 is stopped to complete the installation of the gas cylinder 7. The mounting tube 3 is threadedly connected to the support sleeve 2, which facilitates the installation and disassembly of the mounting tube 3 and the gas cylinder 7, thereby improving the work efficiency of the user.

[0070] After the installation of the gas cylinder 7 is completed, the user pushes the gas cylinder 7, and the gas in the gas cylinder 7 rushes into the gas storage chamber 201. At this time, the gas pressure in the gas storage chamber 201 gradually increases. Then, the user presses the electric control button, and the electric control valve in the needle 4 opens, and the gas in the gas storage chamber 201 is discharged from the needle 4. At the same time, the driving device of the syringe 6 pushes the piston part thereon, so that the medicine in the syringe 6 is pushed into the needle 4. The medicine entering the needle 4 is ejected under the push of the high-pressure gas. In the process of the high-pressure gas pushing the medicine through the needle 4, since the inner diameter of the needle 4 is extremely thin, under the action of the needle 4, the high-pressure gas and the medicine form a liquid column, and the liquid column penetrates the skin and sprays into the subcutaneous tissue, thereby completing the injection of the medicine.

[0071] The user can observe the amount of medicine in the syringe 6 through the cover. When the medicine in the syringe 6 is used up or the gas pressure in the gas cylinder 7 is insufficient, the user can push the mounting tube 3 out through the reset component and take out the gas cylinder 7, thereby completing the replacement of the gas cylinder 7 and the syringe 6.

[0072] Further, please refer to Figure 5 , Figure 7 and Figure 8 The reset assembly includes: a limit plate 21, which is slidably connected in the support sleeve 2 and is squeezed and matched with the installation tube 3; a first elastic member 22, which is fixed between the limit plate 21 and the support sleeve 2; a pressure relief chamber 202 is provided in the support sleeve 2, and the pressure relief chamber 202 is connected to the air storage chamber 201; a truncated cone-shaped groove is provided on one side of the support sleeve 2 close to the pressure relief chamber 202, and the groove is located at the connection point between the pressure relief chamber 202 and the air storage chamber 201.

[0073] It is worth mentioning that the limit plate 21 is used to limit the gas cylinder 7. When the limit plate 21 stops moving, the gas cylinder 7 has been installed in place; the first elastic member 22 is a spring, and is in a compressed state in the figure (after the gas cylinder 7 is installed); the mouth of the gas cylinder 7 is located in the pressure relief chamber 202, and the pressure relief chamber 202 is used to buffer the high-pressure gas in the gas storage chamber 201 to prevent the high-pressure gas in the gas storage chamber 201 from quickly pushing the gas cylinder 7 out; the above-mentioned bevel is used to guide the mouth of the gas cylinder 7 to facilitate its alignment with the connection with the gas storage chamber 201.

[0074] The working principle of the above scheme is as follows: in the process of rotating the installation cylinder 3 into the support sleeve 2, when the installation cylinder 3 contacts the limit plate 21, the installation cylinder 3 squeezes and pushes the limit plate 21 to move, and the first elastic member 22 is compressed until the bottle mouth of the gas cylinder 7 contacts the support sleeve 2, and then the limit plate 21 stops moving. At this time, it indicates that the gas cylinder 7 is installed in place, and the installation cylinder 3 stops rotating.

[0075] After the gas pressure in the gas cylinder 7 is insufficient, the user stops pushing the gas cylinder 7 and takes out the gas cylinder 7. During the process of taking out the gas cylinder 7, the limiting plate 21 squeezes the mounting tube 3 under the push of the first elastic member 22, and the mounting tube 3 moves outward along the threaded groove. In this way, through the pushing action of the first elastic member 22, the mounting tube 3 carrying the gas cylinder 7 is automatically popped out, further reducing the workload of the user and thereby improving the work efficiency of the user.

[0076] When the mouth of the gas cylinder 7 loses contact with the support sleeve 2 (that is, the gas cylinder 7 loses communication with the gas storage chamber 201), since the gas in the gas storage chamber 201 is still in a high-pressure state at this time, the high-pressure gas in the gas storage chamber 201 will be filled into the pressure relief chamber 202, thereby releasing the pressure in the gas storage chamber 201, preventing the high-pressure gas in the gas storage chamber 201 from pushing the installation tube 3 and the gas cylinder 7 to pop out when the gas cylinder 7 is taken out, thereby causing damage to the user. At the same time, since the installation method of the installation tube 3 is threaded, the thread can also prevent it from popping out quickly.

[0077] Please check Figure 4 , Fig. 9 and Fig.10 The trigger assembly includes: a push cylinder 31, which is threadedly connected to the mounting cylinder 3; a push rod 32, which is slidably connected to the push cylinder 31 and is squeezed and matched with the gas cylinder 7; a second elastic member 33, which is installed between the push cylinder 31 and the push rod 32; a positioning assembly, which is arranged on the support sleeve 2 and is used to limit the mounting cylinder 3 and the gas cylinder 7.

[0078] It is worth mentioning that grooves are provided on the side of the push cylinder 31 away from the support sleeve 2 and the side of the push rod 3 away from the support sleeve 2, which is convenient for the user to rotate and operate; the second elastic member 33 is a tension spring, which is used to drive the push rod 32 to reset.

[0079] The working principle of the above scheme is as follows: after placing the gas cylinder 7 into the installation cylinder 3, the user rotates the push cylinder 31 into the installation cylinder 3, and the push cylinder 31 drives the push rod 32 to enter the installation cylinder 3. The push rod 32 contacts the gas cylinder 7 until the push cylinder 31 cannot move, then stops rotating the push cylinder 31, and then inserts the installation cylinder 3 into the support sleeve 2.

[0080] During the process of inserting the installation tube 3 into the support sleeve 2, when the bottle mouth of the gas cylinder 7 contacts the support sleeve 2, the locking assembly works and fixes the installation tube 3 to prevent it from popping out under the push of the first elastic member 22 and the high-pressure gas in the gas storage chamber 201.

[0081] When the gas in the gas cylinder 7 is filled into the gas storage chamber 201, the user pushes the pushing rod 32, the second elastic member 33 is stretched, and the pushing rod 32 pushes the gas cylinder 7, so that the bottle mouth of the gas cylinder 7 contracts and the gas inside is discharged. When the gas cylinder 7 is pushed to the exhaust state, the locking assembly locks the gas cylinder 7 so that it always remains in the exhaust state. At the same time, the locking assembly is limited to prevent the gas cylinder 7 from being ejected under the push of the high-pressure gas in the gas storage chamber 201.

[0082] When replacing the gas cylinder 7, the locking assembly releases the limit on the gas cylinder 7, the bottle mouth of the gas cylinder 7 is reset, the second elastic member 33 is reset, and then the installation tube 3 is taken out from the support sleeve 2, and then the push tube 31 is reversed to separate it from the installation tube 3, so that the gas cylinder 7 is taken out and replaced.

[0083] Please check Figure 4 , Fig. 9 and Fig.10 The positioning assembly includes: a first sleeve 41, which is fixed to the support sleeve 2 and communicated with the support sleeve 2; a positioning block 42, which is slidably connected to the first sleeve 41, and a limiting hole is provided on the mounting tube 3, the positioning block 42 is limitedly matched with the limiting hole on the mounting tube 3, and the positioning block 42 is limitedly matched with the gas cylinder 7; a third elastic member 43 is arranged between the positioning block 42 and the first sleeve 41; a pressure measuring assembly, which is arranged on the support sleeve 2 and is used to detect the gas pressure in the gas storage chamber 201.

[0084] It is worth mentioning that there are two parts in this scheme, and they are symmetrically distributed; hydraulic oil is filled between the first sleeve 41 and the positioning block 42, and the hydraulic oil is used to drive the positioning block 42 to move; the positioning block 42 is provided with an inclined surface and a protrusion, which is convenient for limiting the gas cylinder 7, and a sealing gasket is provided on the positioning block 42 to ensure the seal between it and the first sleeve 41 to avoid leakage of hydraulic oil; the third elastic member 43 is a tension spring, which is used to drive the positioning block 42 to reset.

[0085] The working principle of the above scheme is as follows: after the installation of the mounting tube 3 and the gas cylinder 7 is completed, the axis of the upper limit hole of the mounting tube 3 is aligned with the axis of the first sleeve 41, and the gas cylinder 7 blocks the limit hole on the mounting tube 3; when the user pushes the push rod 32, the gas cylinder 7 moves and gradually loses the shielding of the upper limit hole of the mounting tube 3, and the gas in the gas cylinder 7 is pumped into the gas storage chamber 201, and the air pressure in the gas storage chamber 201 increases. Thereafter, the gas triggers the pressure measuring assembly to work. After the pressure measuring assembly works, the hydraulic oil in the first sleeve 41 increases, and the hydraulic oil in the first sleeve 41 pushes the positioning block 42 to move (the third elastic member 43 is stretched), so that the positioning block 42 enters the limiting hole of the mounting tube 3, and with the movement of the gas cylinder 7, the air pressure in the gas storage chamber 201 gradually increases until the gas cylinder 7 is driven to completely lose the shielding of the upper limit hole of the mounting tube 3, and the positioning block 42 passes through the upper limit hole of the mounting tube 3 and fits with the side of the gas cylinder 7 until the positioning block 42 cannot move.

[0086] After the blocking block 42 stops moving, the user stops pushing the push rod 32, and the push rod 32 is reset under the drive of the second elastic member 33. At this time, the gas cylinder 7 cannot move due to the limiting effect of the blocking block 42, so that the gas cylinder 7 is always in an inflated state, thereby replacing the user to always push the gas cylinder 7. At the same time, it ensures that the gas cylinder 7 is always in a stable state, avoiding the gas cylinder 7 from being unstable in connection with the gas storage chamber 201 due to uneven force, thereby preventing the gas in the gas cylinder 7 from entering the gas storage chamber 201.

[0087] When the gas pressure in the gas cylinder 7 is insufficient, the gas pressure in the gas storage chamber 201 decreases, the pressure measuring assembly controls the oil pressure in the first sleeve 41 to decrease, the positioning block 42 is reset under the drive of the third elastic member 43, and loses the limiting position on the mounting tube 3 and the gas cylinder 7. Thereafter, the user disassembles and replaces the mounting tube 3 and the gas cylinder 7.

[0088] Please check Figure 4 , Figure 5 and Figure 8 The pressure measuring assembly includes: a second sleeve 51, which is fixed to the support sleeve 2 and connected to the air storage chamber 201, and a connecting pipe is connected between the second sleeve 51 and the first sleeve 41; a detection plate 52, which is slidably connected in the second sleeve 51; and a fourth elastic member 53, which is arranged between the second sleeve 51 and the detection plate 52.

[0089] It is worth mentioning that there are two parts in this scheme, and they are symmetrically distributed; hydraulic oil is filled between the second sleeve 51 and the detection plate 52, and the connecting pipe is also filled with hydraulic oil to ensure the transmission of power of the detection plate 52; a sealing gasket is arranged on the peripheral side of the detection plate 52 to ensure the seal between it and the second sleeve 51; the fourth elastic member 53 is a spring, which is used to drive the detection plate 52 to reset, and the side of the detection plate 52 facing the air storage chamber 201 is arranged as an arc-shaped surface, and the curvature of the arc-shaped surface is consistent with the curvature of the inner wall of the air storage chamber 201, thereby ensuring that in the initial state, the arc-shaped surface of the detection plate 52 and the inner wall of the air storage chamber 201 are on the same curved surface, thereby reducing the fluctuation of the gas in the air storage chamber 201.

[0090] The working principle of the above scheme is as follows: after the gas in the gas cylinder 7 is filled into the gas storage chamber 201, as the gas pressure in the gas storage chamber 201 increases, the gas therein pushes the detection plate 52 to move, and the fourth elastic member 53 begins to compress. At the same time, the detection plate 52 squeezes the hydraulic oil in the second sleeve 51, and the oil pressure in the second sleeve 51 increases. The hydraulic oil flows into the first sleeve 41 along the connecting pipe, and the hydraulic oil pushes the positioning block 42 to move, thereby completing the limiting of the mounting tube 3 and the gas cylinder 7.

[0091] When the gas pressure in the gas cylinder 7 is insufficient, the pressure in the gas storage chamber 201 decreases, the fourth elastic member 53 begins to reset and drives the detection plate 52 to move. During this process, the pressure in the second sleeve 51 decreases, the hydraulic oil in the first sleeve 41 flows back to the second sleeve 51, the positioning block 42 resets and releases the limit on the mounting tube 3 and the gas cylinder 7, until the fourth elastic member 53 and the detection plate 52 are completely reset, and the positioning block 42 is also completely reset.

[0092] Embodiment 2: During the exhaust process of the gas cylinder 7, as the gas pressure therein gradually decreases, the pressure discharged from the gas cylinder 7 will also gradually decrease. If the injection amount of the syringe 6 does not change at this time, the amount of the medicine liquid and the high-pressure gas will not match, and the medicine liquid will not be completely pushed by the high-pressure gas, resulting in the inability of the medicine liquid to enter the subcutaneous tissue, causing a waste of the medicine liquid.

[0093] To solve the above problems, the following solutions are proposed, specifically: Figure 4 and Fig.11 , and also includes: a driving component, which is arranged in the shell 1 and is used to adjust the discharge amount of the syringe 6. The driving component includes: a driving member 61, which is installed in the shell 1; a pushing plate 62, which is slidably connected to the mounting plate 5 and is squeezed and matched with the piston part of the syringe 6, and the pushing plate 62 is fixedly connected to the power output end of the driving member 61; a sensor 63, which is installed on the support sleeve 2 and is located in the air storage chamber 201.

[0094] It is worth mentioning that the driving member 61 is an existing driving structure. What is shown in this article is an electric reciprocating screw structure, but it is not limited to this. It can realize lateral movement, such as an electric push rod, a hydraulic push rod, etc.; the sensor 63 is a pressure sensor, which is used to detect the pressure in the air storage chamber 201, and then control the movement of the driving member 61.

[0095] The working principle of the above scheme is as follows: during the process of the gas cylinder 7 inflating the gas storage chamber 201 , the sensor 63 is always in working state and detects the gas pressure in the gas storage chamber 201 in real time.

[0096] When the pressure of the gas in the gas storage chamber 201 reaches the set value, the user opens the driving member 61 and the electric control valve in the needle 4, the driving member 61 pushes the push plate 62, and the push plate 62 pushes the piston part of the syringe 6, and the liquid medicine in the syringe 6 and the gas in the gas storage chamber 201 enter the needle 4 together. At this time, the discharge amount of the liquid medicine and the gas is in a certain proportion, and then the drug injection operation is started. During this process, the gas in the gas cylinder 7 is discharged at a uniform speed, and the pressure in the gas storage chamber 201 is constant. At the same time, the driving member 61 drives the push plate 62 to move at a uniform speed, so that the speed of the syringe 6 discharging the drug is in a uniform state. At this time, the sensor 63 has been detecting the pressure of the gas in the gas storage chamber 201.

[0097] When the pressure of the gas in the gas cylinder 7 decreases, the amount of gas discharged from the gas cylinder 7 will also decrease, causing the pressure in the gas storage chamber 201 to decrease. At this time, the amount of liquid medicine discharged is not proportional to the amount of gas discharged. After the sensor 63 detects the pressure reduction, the sensor 63 controls the driving member 61 to reduce the moving speed, thereby reducing the speed at which the syringe 6 discharges medicine, thereby ensuring that the amount of gas discharged is in a certain proportion to the amount of liquid medicine discharged, thereby improving the utilization rate of the liquid medicine and reducing the waste of the liquid medicine.

[0098] Example 3: During the use of this device, its main purpose is to assist in cleaning the face. The medicine liquid will not completely enter the skin, and some of the medicine liquid will remain on the skin surface. However, during the use of this device, the user is usually asked to lie flat on the bed, and the user then uses the device to operate. However, when there is too much medicine liquid remaining on the user's face, it will flow along the face to other locations, and then contaminate other locations.

[0099] To solve the above problems, the following solutions are proposed, specifically: Figure 1 , Figure 2 and Fig.12 , further comprising: a buffer cover 71 fixedly connected to the outer shell 1 ; a water absorbing member 72 fixedly connected to the outer shell 1 and located inside the buffer cover 71 .

[0100] It is worth mentioning that the buffer cover 71 is made of soft rubber material to ensure that the buffer cover 71 fits fully with the user's face, intercepts the medicine remaining on the face, and prevents the medicine from flowing; the absorbent part 72 is a sponge. During the movement, the absorbent part 72 absorbs and stores the medicine intercepted by the buffer cover 71. When the device is used up, the user removes the buffer cover 71 and the absorbent part 72, and squeezes out the medicine in the absorbent part 72 for the next use.

[0101] Example 4: This example provides a method for using a non-invasive mesotherapy device. Figure 1-Figure 12 , which can be applied to a non-invasive mesotherapy device in the above embodiment, and the method of use is as follows:

[0102] Step 1: Place the syringe 6 on the mounting plate 5, and place the gas cylinder 7 into the mounting tube 3, and then fix the push tube 31 on the mounting tube 3, so that the push rod 32 is in contact with the gas cylinder 7;

[0103] Step 2: After the push rod 32 contacts the gas cylinder 7, the installation cylinder 3 is inserted into the support sleeve 2 until the mouth of the gas cylinder 7 contacts the support sleeve 2, and the movement of the installation cylinder 3 is stopped. During this process, the installation cylinder 3 squeezes the limiting plate 21 and the first elastic member 22 is compressed;

[0104] Step 3: After the moving installation cylinder 3 stops, the push rod 32 is pressed, and the push rod 32 pushes the gas cylinder 7, and the gas cylinder 7 pumps high-pressure gas into the gas storage chamber 201;

[0105] Step 4: The pressure in the gas storage chamber 201 increases, the detection plate 52 moves and pushes the hydraulic oil, so that the hydraulic oil drives the positioning block 42 to move, and the positioning block 42 is inserted into the upper limit hole of the installation cylinder 3 and contacts one side of the gas cylinder 7. At this time, the positioning block 42 limits the installation cylinder 3 and the gas cylinder 7, and the gas cylinder 7 is in the exhaust state;

[0106] Step 5: After the gas storage chamber 201 is filled with high-pressure gas, the high-pressure gas in the gas storage chamber 201 and the liquid in the syringe 6 enter the needle 4 together and are discharged from the needle 4 to the skin;

[0107] Step 6: After the air pressure in the gas cylinder 7 decreases, the sensor 63 also detects that the pressure in the gas storage chamber 201 decreases, and the sensor 63 controls the driving member 61 to reduce the moving speed of the push plate 62;

[0108] Step 7: When the gas pressure in the gas cylinder 7 is insufficient, the detection plate 52 is reset, and the positioning block 42 releases the limit of the installation tube 3 and the gas cylinder 7;

[0109] Step 8: The gas cylinder 7 and the mounting tube 3 are reset under the action of the first elastic member 22, and the gas cylinder 7 and the mounting tube 3 are taken out and replaced.
