Description
Technical Field
[0001] The utility model relates to the field of medical devices, in particular to a hydrodermoneedle device. Background Art
[0002] Hydrodermoneedles are widely used in the medical beauty industry to inject treatment fluids such as hyaluronic acid into the skin through needles, thereby achieving the purpose of beauty treatment.
[0003] A needle seat is provided around the needle of the hydrodermoneedle device. A space is formed between the needle seat and the needle. A pipe is connected to the side wall of the needle seat. While the needle seat is attached to the outside of the skin and the needle injects the treatment fluid, the pipe extracts the air in the space to generate negative pressure in the space to suck up the skin, so as to prevent the treatment fluid from leaking. At the same time, the sucked-up skin can also assist the human body in absorbing the treatment fluid and prevent side effects such as pain in the human body. However, under the action of negative pressure, some dirt will be sucked into the pipe or adsorbed on the inner wall of the needle seat, such as the leaked treatment fluid or the blood oozing out due to the puncture of the human skin. This makes it necessary to clean the pipe after the injection of the hydrodermoneedle device. In the prior art, gas is introduced into the pipe that sucks the patient's body fluid to blow out the dirt in the pipe. However, some stubborn dirt still adheres to the inner walls of the pipe and the needle seat. Since the needle and the needle seat of the hydrodermoneedle are in the same space and the needle will be inserted into the human body, it is very easy to cause cross-infection and pose a safety hazard to the patient.

[0026] Reference Figures 1 to 5 , a hydrodermabrasion needle device according to a preferred embodiment of the present utility model will be elaborated in detail below. The hydrodermabrasion needle device is used to inject a treatment fluid into the human body. The hydrodermabrasion needle device includes a device main body 10, an injection assembly 20, a suction assembly 30, and a cleaning assembly 40.
[0027] As Figure 2 and Figure 3 shown, the injection assembly 20 includes a syringe barrel 21, a piston 22, and a needle head 23. Among them, the syringe barrel 21 is detachably installed on the device main body 10, and the syringe barrel 21 is used to accommodate the treatment fluid. The piston 22 is slidably installed inside the syringe barrel 21. The needle head 23 includes a needle head main body 231 and a needle seat 232. Among them, the needle head main body 231 is detachably installed at the end of the syringe barrel 21 away from the piston 22 to facilitate the syringe barrel 21 to suck the treatment fluid. The needle seat 232 is arranged around the end of the needle head main body 231 inserted into the human body and forms a needle head space 2301 with the needle head main body 231. The needle head main body 231 communicates with the syringe barrel 21, and the needle head main body 231 can pierce into the human body. When the needle head main body 231 pierces into the human body, the treatment fluid inside the syringe barrel 21 can be squeezed by the sliding piston 22 and injected into the human body from the needle head main body 231.
[0028] The sucking component 30 is installed on the device main body 10. The sucking component 30 includes a connecting pipe 31, a gas pipe 32, and at least one conveying member 33. One end of the connecting pipe 31 communicates with the needle space 2301, and the other end communicates with the gas pipe 32. The conveying member 33 communicates with the connecting pipe 31 and the gas pipe 32, and the conveying member 33 can generate a negative pressure inside the connecting pipe 31, so that gas can be controllably sucked out from the needle space 2301 through the connecting pipe 31 and the gas pipe 32. Furthermore, a negative pressure is generated in the needle space 2301 to suck up the skin and simultaneously suck in dirt.
[0029] It can be understood that when the conveying member 33 operates to suck the gas in the needle space 2301 through the gas pipe 32 to form a negative pressure in the needle space 2301, the gas pressure in the needle space 2301 decreases, and the skin of the human body will be sucked up to prevent the leakage of the treatment liquid. At the same time, the sucked-up skin can also assist the human body in absorbing the treatment liquid and prevent side effects such as pain in the human body. However, under the action of the negative pressure, some dirt will be sucked into the connecting pipe 31 or adsorbed on the inner wall of the needle base 232, so a cleaning operation is required.
[0030] As an example, the conveying member 33 is implemented as a negative pressure pump.
[0031] The cleaning component 40 includes a liquid pipe 41 and a valve assembly 42. One end of the liquid pipe 41 communicates with the connecting pipe 31. The liquid pipe 41 is arranged to allow the passage of cleaning liquid, and the liquid pipe 41 communicates with the conveying member 33, so that the cleaning liquid can enter the connecting pipe 31 under the negative pressure of the conveying member 33 to clean the dirt in the connecting pipe 31 and the needle space 2301. The valve assembly 42 includes a gas valve 421 and a liquid valve 422. The gas valve 421 is installed on the gas pipe 32, and the liquid valve 422 is installed on the liquid pipe 41. The gas valve 421 and the liquid valve 422 can be controlled by the operator to block the pipeline. The gas pipe 32 is arranged to allow the passage of gas, so that when gas is introduced into the gas pipe 32 or liquid is introduced into the liquid pipe 41, the gas or liquid will only rush into the needle space 2301 from the connecting pipe 31 and then be discharged.
[0032] It is worth mentioning that when the hydrodermoneedle device is in treatment, the gas valve 421 is opened to convey the gas in the needle space 2301 out of the gas pipe 32 under the negative pressure generated by the conveying member 33, creating a negative pressure environment for injection, reducing skin swelling and facilitating the patient's absorption of the treatment fluid. At the same time, the liquid valve 422 is closed to prevent the liquid introduced into the liquid pipe 41 from interfering with the suction of the suction assembly 30.
[0033] In one embodiment, as Figure 2 shown, the number of the conveying members 33 is implemented as one. The conveying member 33 is arranged on the communicating pipe 31. In this way, one conveying member 33 can complete the conveyance of gas and liquid.
[0034] In another embodiment, as Figure 4 shown, the number of the conveying members 33 is implemented as two. One conveying member 33 is respectively installed on the gas pipe 32 and the liquid pipe 41. In this way, gas and liquid can be conveyed by their respective conveying members 33.
[0035] It can be understood that when the gas valve 421 is opened and the liquid valve 422 is closed, the conveying member 33 conveys gas into the communicating pipe 31 and the needle space 2301 to blow away most of the dirt in the communicating pipe 31 and the needle space 2301; when the gas valve 421 is closed and the liquid valve 422 is opened, the conveying member 33 conveys the cleaning liquid into the communicating pipe 31 and the needle space 2301 to deeply clean the dirt in the communicating pipe 31 and the needle space 2301.
[0036] Those skilled in the art can understand that before the injection starts, the operator installs the syringe 21 filled with the treatment fluid inside on the device main body 10, and then installs the needle 23 on the end of the syringe 21 away from the piston 22; when the needle body 231 penetrates into the human body, the piston 22 slides in the direction close to the needle 23, thereby squeezing the treatment fluid located inside the syringe 21, so that the treatment fluid is injected into the human body through the needle body 231; at the same time, the needle base 232 fits on the human body surface, the opening of the needle space 2301 is blocked by the human skin, and the conveying member 33 makes a negative pressure generated in the needle space 2301, thereby sucking up the human skin through the suction assembly 30; after the injection is completed, the gas valve 421 and the liquid valve 422 are opened successively, so that under the conveyance of the conveying member 33, the dirt in the communicating pipe 31 and the needle space 2301 is cleaned to avoid affecting the health of the next user.
[0037] Preferably, the hydrodermabrasion device further includes a displacement assembly 50, which is installed on the device main body 10 and is configured to drive the piston 22 to reciprocate in the syringe barrel 21.
[0038] Preferably, as Figure 2 shown, the displacement assembly 50 includes a driving member 51 and a driving belt member 52. The driving member 51 is installed on the device main body 10. The driving belt member 52 is slidably installed on the end of the piston 22 away from the syringe barrel 21 along the sliding direction of the piston 22, and the driving belt member 52 can be driven by the driving member 51 to slide along the sliding direction of the piston 22. In this way, the driving belt member 52 driven by the driving member 51 can drive the piston 22 to slide in the syringe barrel 21, so as to inject the treatment liquid in the syringe barrel 21 out through the needle head 23.
[0039] As an example, the driving member 51 is implemented as a cylinder. The driving belt member 52 is implemented as a slider.
[0040] Preferably, the driving member 51 includes a driving piece 511 and a screw rod 512. The driving piece 511 is installed on the device main body 10. The screw rod 512 is drivably connected to the driving piece 511 and is parallel to the sliding direction of the piston 22, so that the driving piece 511 can drive the screw rod 512 to rotate. The driving belt member 52 is threadedly connected to the screw rod 512 and is clamped to the end of the piston 22 away from the syringe barrel 21. When the screw rod 512 rotates, the driving belt member 52 reciprocates along the sliding direction of the piston 22, and then drives the piston 22 to reciprocate. When moving towards the needle head 23, the driving belt member 52 pushes the piston 22 to squeeze the treatment liquid in the syringe barrel 21.
[0041] Preferably, the cleaning assembly 40 further includes a cleaning container 43 for containing cleaning liquid. The cleaning container 43 is installed on the device main body 10 and is configured to communicate with the outside to add cleaning liquid when the amount of cleaning liquid is too small. The end of the liquid pipe 41 away from the connecting pipe 31 communicates with the cleaning container 43, so that the hydrodermabrasion device can perform cleaning operations at any time.
[0042] Preferably, as Figure 5As shown, the hydrodermabrasion needle device further includes a fastening assembly 60, and the fastening assembly 60 includes two fasteners 61 and a fastening screw 62. The two fasteners 61 are slidably mounted on the device main body 10 along a direction perpendicular to the extending direction of the syringe barrel 21, and the two fasteners 61 are relatively located on both sides of the syringe barrel 21 to sandwich the syringe barrel 21 in the middle. The fastening screw 62 passes through the two fasteners 61 and is screwed to the two fasteners 61, and the threads on the two fasteners 61 are opposite, so that when the fastening screw 62 rotates, the two fasteners 61 approach or move away from each other, thereby fastening or releasing the syringe barrel 21, so as to disassemble and assemble the injection assembly 20 and increase the firmness of the injection assembly 20 after assembly.
[0043] Preferably, the fastening screw 62 is arranged to be connected to a driving motor, so that the fastening screw 62 rotates, and then drives the two fasteners 61 to approach or move away from the syringe barrel 21, and fastens the syringe barrel 21 when approaching the syringe barrel 21. In this way, syringe barrels 21 of different sizes can be fixed on the device main body 10 by the fastening assembly 60.
[0044] It is worth mentioning that since the sizes of the syringe barrels 21 applied in the hydrodermabrasion needle device do not vary much, the method of using a driving motor to drive the fastening screw 62 is too wasteful, after all, the distance that the two fasteners 61 need to move is small.
[0045] More preferably, as Figure 1 and Figure 5 shown, the device main body 10 forms an installation space 101, a part of the two fasteners 61 is arranged in the installation space 101, the fastening screw 62 passes through the fasteners 61 located in the installation space 101 and at least one end passes through the wall of the installation space 101 formed by the device main body 10, and a hand-twisting part 621 is formed at one end of the fastening screw 62 outside the installation space 101. The hand-twisting part 621 can be hand-twisted by an operator, so that the fastening screw 62 is twisted and rotated by the operator, and then drives the two fasteners 61 to approach or move away from the syringe barrel 21, and fastens the syringe barrel 21 when approaching the syringe barrel 21. In this way, the syringe barrel 21 can be fastened and it does not need to be driven by a driving motor, which is very convenient.
[0046] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
