Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, in particular to a portable introduction instrument. Background Art

[0002] Since applying liquid medicine directly to the surface of the skin has a low performance and is not conducive to human absorption, an introduction instrument has come into being. The introduction instrument can introduce the liquid medicine into the deep layer of the skin through microneedles, allowing the skin to better absorb the introduction liquid and improve the effect of the introduction liquid. Existing introduction instruments are mainly large equipment or simple puncture devices, which have many inconveniences.

[0003] For example, the existing microneedle introduction device with Chinese patent number CN117205433A is mainly composed of a drive component, a connecting catheter, an injection needle, etc., and is limited to the introduction of liquid medicines through multiple and dense needles. Individual application conditions are limited and it cannot be carried with the individual. The needle tip is large and only has an introduction function without massage, smearing and other functions. The pain is too severe and needs to be combined with surface anesthetic drugs. It is not conducive to personal use at home and on the go, and is not suitable for use on the surface of nerve-rich skin tissue. For example, the existing handheld microneedle beauty introduction device with Chinese patent number CN209333005U and the handheld beauty liquid automatic introduction device with Chinese patent number CN215194983U do not have a massage function, and the liquid used is discharged separately, that is, it is applied first and then introduced. There are low accuracy and uneven application of the medicine, and both lack a blow-drying operation. For patients who have social needs after taking the medicine, after applying the medicine in the morning, the hair on the body surface will be affected by the application of the medicine and the hair will be affected in terms of fluffiness, resulting in visual greasy hair, which affects daily social interaction.

[0004] Therefore, in order to solve such problems, we proposed a portable introduction instrument. Summary of the Invention

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figure 1 - Figure 12 The portable introduction instrument includes a shell 1. The upper side of the shell 1 is matched with a sleeve 2 and a protrusion 3. The top of the sleeve 2 is coaxially corresponding and detachably fixed with a docking sleeve 4. The sleeve 2 can be fixed with the docking sleeve 4 by snapping or threading. A reciprocating rod 6 is slidably connected inside the docking sleeve 4. A disc block 7 is coaxially fixed to one end of the reciprocating rod 6. A plurality of microneedle tubes 8 are provided at the end of the disc block 7 facing away from the reciprocating rod 6. The plurality of microneedle tubes 8 are used for skin-breaking operations. The microneedle tubes 8 can also be used for injecting liquid medicine. The microneedle tubes 8 are provided with channels for passing liquid medicine. The front end of the microneedle tubes 8 is spike-shaped and has micropores connected to the channels. The liquid medicine can be discharged from the micropores. The spike-shaped front end is used to puncture the skin, and the micropores are used to inject liquid medicine. The other end of the reciprocating rod 6 is provided with a liquid storage structure for supplying liquid to the plurality of microneedle tubes 8. The sleeve 2 is provided with a driving structure for driving the reciprocating rod 6 to move back and forth. The shell 1 is also provided with a blowing and drying structure.

[0039] The housing 1 can be provided in various shapes and specifications, such as Figure 11 As shown, Figure 1 a is a circle, Figure 1 b is a triangle, Figure 1 c is a rectangle, Figure 1 d is a pentagon, and the housing 1 is not limited to the above shape, and can also be set to other feasible shapes, and the corresponding sleeves 2 and protrusions 3 are arranged on the surface of the housing 1.

[0040] As a technical optimization solution of the present invention, the bottom edges of the projection 3 and the docking sleeve 4 are both provided with identical threads. Several threaded holes 5 are provided on the upper side of the housing 1, into which the projection 3 and the docking sleeve 4 can be threadedly connected. Furthermore, a handle structure corresponding to the docking sleeve 4 is provided at the bottom of the housing 1, and an ice bead 34 is mounted on the top of the projection 3. The docking sleeve 4 can be threadedly connected to the threaded holes 5, thereby assembling the sleeve 2 and its components with the housing 1. The projection 3 can be threadedly connected to the threaded holes 5, thereby assembling the projection 3 and the ice bead 34 with the housing 1.

[0041] The above-mentioned ice beads 34 are existing metal balls, such as medical-grade 304 / 316 stainless steel balls. Before use, the ice beads 34 can be refrigerated to make their temperature lower than that of the skin, or soaked in hot water to make their temperature the same as or higher than that of the skin. The bump 3 is in the shape of a pointed cone, and the ice beads 34 are movably connected to the pointed cone end of the bump 3. The ice beads 34 can achieve a universal rotation effect, wherein the mechanical pressure generated by the rolling can relax the fascia and improve local circulation; and the low temperature of the ice beads 34 causes the blood vessels to contract / relax in stages, accelerates the removal of metabolic waste, and enhances the repair capacity. The ice beads 34 can achieve the effect of dilating blood vessels and improving tissue oxygen supply through the dual-effect synergy of "low temperature + mechanical stimulation" or "high temperature + mechanical stimulation". This device is prohibited for people with damaged skin, a history of frostbite, or blood circulation disorders.

[0042] As a technical optimization solution of the present invention, the handle structure includes a handle body 9, which is detachably fixed to the bottom of the housing 1, that is, it can be fixedly installed by bolts. The handle body 9 has a cavity that matches the sleeve 2. The middle portion of the handle body 9 is coaxially aligned with the docking sleeve 4 and the corresponding threaded hole 5. In other words, if the sleeve 2 is longer than the housing 1, the handle body 9 can provide an additional cavity to facilitate the installation of the sleeve 2. The handle body 9 is used to facilitate the operation of the housing 1 by hand.

[0043] The handle body 9 is not limited to one specification. Figure 12 As shown, the handle body 9 can be configured as follows Figure 12 The columnar shape shown in a can provide a cavity for the sleeve 2 to be set; Figure 12 b shows an inverted T-shape, in which a cavity corresponding to the sleeve 2 can be provided in the middle of the T-shape; Figure 12 As shown in c, the middle and side of the rectangular block can be provided with cavities corresponding to the sleeve 2, that is, multiple sleeves 2 can be provided, respectively located in the middle or on the side; Figure 12 d shows a two-section handle arrangement, with the two ends of the handle connected by a ball shaft, the housing 1 being connected to one of the handles, which is provided with a cavity corresponding to the sleeve 2. The handle body 9 is not limited to the above specifications, and may also be provided with other feasible specifications and shapes.

[0044] As a technical optimization solution of the present invention, a cross bar 10 is fixed transversely inside the docking sleeve 4, and the reciprocating rod 6 slides through the cross bar 10. The cross bar 10 has the effect of limiting the reciprocating rod 6, and can ensure that the reciprocating rod 6 slides and moves along the two ends of the docking sleeve 4. An annular stopper 11 is also coaxially fixed to the reciprocating rod 6. The annular stopper 11 is away from the disc block 7, and a first spring 12 is provided between the annular stopper 11 and the cross bar 10. The two ends of the first spring 12 are fixedly connected to the annular stopper 11 and the cross bar 10 respectively. The first spring 12 has the effect of resetting the reciprocating rod 6, so that the reciprocating rod 6 is reset after a disturbance, that is, after the reciprocating rod 6 is pushed toward one end of the disc block 7 by an external force, the first spring 12 can pull it back to its original position after the external force is removed, and the reciprocating rod 6 can achieve reciprocating telescopic movement.

[0045] As a technical optimization solution of the present invention, the end of the docking sleeve 4 facing away from the sleeve 2 is threadedly connected to a protective shell 13. The protective shell 13 is cylindrical, and the disc block 7 slides and mates with the inner wall of the protective shell 13. When the first spring 12 is in its natural state, the microneedle tubes 8 are all located within the end of the protective shell 13. The height of the end of the protective shell 13 is lower than the height of the ice bead 34 by 2 to 3 mm. In other words, the telescopic movement of the reciprocating rod 6 drives the disc block 7 to move, and thus the microneedle tubes 8. By operating the housing 1 by holding the handle body 9, the ice bead 34 of the protrusions 3 is brought into contact with the patient's skin, while the protective shell 13 is directed toward the patient's skin. As the reciprocating rod 6 drives the disc block 7 forward, the corresponding microneedle tubes 8 are able to pass the end of the protective shell 13. The disc block 7 moves forward a distance sufficient for the microneedle tubes 8 to puncture the skin. When the reciprocating rod 6 is not moving, the protective shell 13 provides protection, preventing the microneedle tubes 8 from puncturing the skin. Furthermore, the protective shell 13 can also adjust the distance between its port and the plurality of microneedle tubes 8 by rotating, thereby controlling the depth at which the microneedle tubes 8 pierce the skin.

[0046] As a technical optimization solution of the present invention, the liquid storage structure includes a liquid storage capsule 14. The liquid storage capsule 14 is used to place a corresponding amount of liquid medicine inside, which plays a temporary storage role and is convenient for subsequent direct use. The top of the liquid storage capsule 14 is provided with a port and the port is threadedly connected to a cover 15. The port of the liquid storage capsule 14 is made of hard plastic and can be effectively threaded and fixed with the cover 15. The cover 15 is provided with a number of liquid outlets 16. A sponge layer 17 is attached to the upper side of the cover 15. The sponge layer 17 is fixedly connected to the cover 15 by a number of clips 18. The clips 18 can be snap-connected to the liquid outlets 16. The number of clips 18 is less than the number of liquid outlets 16. The sponge layer 17 can be installed and fixed to the cover 15 by the clips 18. After the sponge layer 17 is installed, the several liquid outlets 16 allow the liquid medicine to pass through and soak the sponge layer 17. The sponge layer 17 absorbs water and maintains the liquid volume through capillary action. When left stationary, the water will sink under gravity.

[0047] As a technical optimization solution of the present invention, the lower end of the reciprocating rod 6 is connected to a first placement shell 21, the bottom of the first placement shell 21 is provided with an opening, the liquid storage capsule 14 is arranged in the first placement shell 21, and the top of the first placement shell 21 is provided with a rubber expansion cavity 22 corresponding to the sponge layer 17, the rubber expansion cavity 22 can be stretched in length, and the side of the rubber expansion cavity 22 can be set to be corrugated to facilitate the stretching operation. The rubber expansion cavity 22 is fixedly connected to the bottom of the reciprocating rod 6, and the thickness of the sponge layer 17 is not limited to one thickness specification. The sponge layer 17 can be set to a variety of thickness specifications, and its thickness is within the range of the rubber expansion cavity 22. For example, the thickness of the sponge layer 17 is half the thickness of the inside of the rubber expansion cavity 22 or the same as the thickness of the rubber expansion cavity 22. The thicker the sponge layer 17 is, the more water it absorbs. The microneedle tubes 8 are respectively connected to and communicate with a plurality of spiral tubes 23, which are spirally arranged around the interior of the reciprocating rod 6. The reciprocating rod 6 has an inner cavity corresponding to the spiral tubes 23. One end of each spiral tube 23 passes through the top of the rubber expansion cavity 22 and communicates with its interior. That is, a plate is fixed transversely inside the rubber expansion cavity 22, and the spiral tubes 23 pass through the plate and communicate with one end of the corresponding sponge layer 17. The spiral tubes 23 serve to communicate the liquid medicine. After the sponge layer 17 is squeezed, the liquid is squeezed out from the interior. At this time, some of the liquid is squeezed back into the liquid reservoir 14, while the other part of the liquid is squeezed and transported through the spiral tubes 23 to the corresponding microneedle tubes 8, and then discharged from the microneedle tubes 8. The capillary effect of the sponge layer 17 can prevent the liquid medicine from flowing out when it is stationary.

[0048] The above-mentioned several spiral tubes 23 are used to transfer the drug solution, and are not limited to setting up several spiral tubes 23 for transferring the drug solution. Several spiral grooves can also be set. Several spiral grooves also have small gaps, which can achieve a capillary effect. The capillary effect can prevent the drug solution from flowing out in a static state. The drug solution can be absorbed through the capillary effect and transferred to several microneedle tubes 8. By setting a sponge layer 17 and squeezing the sponge layer 17, the effect of increasing the amount of transferred liquid can also be achieved.

[0049] As a technical optimization solution of the present invention, an annular block 19 is provided at the bottom of the liquid storage capsule 14, and a number of slide bars 20 are fixed on the annular block 19. A slot hole that is engaged and slidably matched with the slide bars 20 is provided at the bottom of the liquid storage capsule 14, and a second spring 24 is fixed in the slot hole. The other end of the second spring 24 is fixedly connected to the corresponding slide bar 20. The annular block 19 can be coaxially aligned with the port at the bottom of the first placement shell 21 and snap-connected. The annular block 19 plays the role of positioning and installing the liquid storage capsule 14 inside the first placement shell 21. After the liquid storage capsule 14 is set inside the first placement shell 21, it can achieve telescopic sliding through the number of slide bars 20, and the corresponding second spring 24 plays the role of resetting the liquid storage capsule 14.

[0050] As a technical optimization solution of the present invention, the drive structure includes a second placement shell 25, the top of which is also provided with an opening, and the top of the second placement shell 25 is detachably fixedly connected to the bottom of the first placement shell 21. The first placement shell 21 and the second placement shell 25 can be fixed by snapping or threaded. The first placement shell 21 and the second placement shell 25 are both snap-fitted and positioned inside the sleeve 2. A telescopic motor 26 is fixed inside the second placement shell 25. The telescopic motor 26 is coaxially provided with a driving end 27, which can slide and match with the inner side of the annular block 19. A rubber protrusion 28 is provided at the bottom of the liquid storage capsule 14. The telescopic motor 26 can control the reciprocating telescopic movement of the driving end 27. The movement of the driving end 27 can push the liquid storage capsule 14, and the driving end 27 first contacts the rubber protrusion 28 at the bottom of the liquid storage capsule 14, achieving the effect of squeezing the rubber protrusion 28, causing the rubber protrusion 28 to deform, and then can push the inside of the liquid storage capsule 14, ultimately achieving the effect of pushing the internal liquid.

[0051] The telescopic motor 26 is an existing linear reduction motor, which can realize the reciprocating drive operation of the driving end 27. It also includes a battery for powering the telescopic motor 26. The battery and the telescopic motor 26 are arranged in a box body. The battery can be set to be detachable or rechargeable.

[0052] As a technical optimization scheme of the present invention, the blowing and drying structure includes several annular blocks 29 and an air inlet pipe 35. The several annular blocks 29 are coaxially aligned with the several threaded holes 5 respectively. The radius of the annular block 29 is larger than the radius of the threaded hole 5. The shell 1 is provided with an annular groove matching the several annular blocks 29. Several air outlet nozzles 30 are evenly provided on the upper side of the annular block 29. A docking nozzle 31 is provided on the side of the shell 1. Several annular blocks 29 are connected and communicated with the docking nozzle 31 through a connecting pipe 32. An annular cavity connecting the several air outlet nozzles 30 and the connecting pipe 32 is provided in the annular block 29. The air inlet pipe 35 can be detachably fixedly connected to the docking nozzle 31. The other end of the air inlet pipe 35 corresponds to a variable frequency fan device 33. The air inlet pipe 35 can be connected to the air outlet sleeve of the variable frequency fan device 33. An electric heating wire is installed inside the air outlet of the variable frequency fan device 33. The variable frequency fan device 33 can blow air under negative pressure, and the electric heating wire at its air outlet can heat the air, turning it into hot air. The hot air can be blown to the docking nozzle 31 through the air inlet pipe 35, and then enter the interior of several annular blocks 29 from several connecting pipes 32, and finally blown out from several air outlet nozzles 30. When using the control shell 1, the several air outlet nozzles 30 are facing the patient's skin, which can achieve a blowing and drying effect, and the variable frequency fan device 33 can realize alternating hot and cold air, making the application of the medicine more comfortable.

[0053] The above-mentioned variable frequency fan device 33 can also be replaced by an existing hair dryer. The air inlet pipe 35 can be connected to the air outlet of the hair dryer through a sleeve. The existing variable frequency hair dryer can also realize the alternating hot and cold blowing operation.

[0054] When the present invention is in use, the housing 1 is operated by holding the handle body 9 so that the ice beads 34 of the several protrusions 3 fit the patient's skin. During use, the protective shell 13 is facing the patient's skin. As the reciprocating rod 6 drives the disc block 7 to move forward, the corresponding several microneedle tubes 8 can move beyond the port of the protective shell 13. The distance that the disc block 7 moves forward can enable the several microneedle tubes 8 to puncture the skin. When the reciprocating rod 6 is not pushing, the protective shell 13 can play a protective role, that is, prevent the several microneedle tubes 8 from puncturing the skin. The protective shell 13 can also adjust the distance between its port and the several microneedle tubes 8 by rotating, thereby controlling the depth of the microneedle tubes 8 puncturing the skin. The movement of the reciprocating rod 6 is controlled by the telescopic motor 26. Specifically, the telescopic motor 26 controls the movement of the driving end 27. The driving end 27 pushes the liquid reservoir 14, which in turn squeezes the sponge layer 17. After the sponge layer 17 is squeezed, liquid is squeezed out of the sponge layer 17. At this time, some of the liquid is squeezed back into the liquid reservoir 14, while the remaining liquid is squeezed and transported through the spiral tubes 23 to the corresponding microneedle tubes 8, and then discharged from the microneedle tubes 8. After the sponge layer 17 is squeezed to its limit, it can continue to push the rubber telescopic cavity 22, causing it to expand, thereby achieving the effect of pushing the reciprocating rod 6 and moving the reciprocating rod 6.

[0055] During the above operation, the telescopic motor 26 can control the movement of the reciprocating rod 6 and can also achieve the effect of squeezing the sponge layer 17, so that multiple microneedle tubes 8 can perform puncture operations while also achieving multiple microneedle tubes 8 to discharge liquid. The driving end 27 first contacts the rubber protrusion 28 at the bottom of the liquid reservoir 14, squeezing the rubber protrusion 28, causing the rubber protrusion 28 to deform, and then push the rubber protrusion 28 into the interior of the liquid reservoir 14, ultimately impacting the internal liquid, ensuring that liquid is always present in the sponge layer 17. For example, when operating with the upper side of the housing 1 facing upward, the sponge layer 17 is also facing upward. At this time, the liquid cannot enter the sponge layer 17 from the liquid outlet 16 by gravity. At this time, under the push of the rubber protrusion 28, the liquid can be discharged upward from the liquid outlet 16 by impacting the internal liquid, achieving the effect of replenishing the liquid into the sponge layer 17, thereby ensuring the subsequent discharge of the liquid.

[0056] The aforementioned microneedle tubes 8 achieve a puncture frequency by controlling the reciprocating rod 6's extension and retraction frequency via the telescopic motor 26. The first spring 12 resets the reciprocating rod 6, allowing it to return to its original position once the thrust is removed. This allows the microneedle tubes 8 to rebound immediately after contact with the skin. During this brief contact between the microneedle tubes 8 and the skin, the medicinal solution can come into contact with the punctured area. The ice beads 34 roll against the skin during use, providing an instant cooling and massage effect.
