Detailed Implementation
[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0025] See Figures 1-6A novel automated microneedle stimulation drug spraying and hair growth device according to a preferred embodiment of the present invention includes a drug spraying system 100. The drug spraying system 100 includes a mounting plate 101, a microneedle stimulation unit 1 and a drug spraying unit 2 disposed on the mounting plate 101, wherein the microneedle stimulation unit 1 is used to puncture the scalp skin, and the drug spraying unit 2 is used to spray drug onto the punctured scalp skin.
[0026] The microneedle stimulation unit 1 includes a drive mechanism and a microneedle mechanism connected to the drive mechanism. The drive mechanism can drive the microneedle mechanism to reciprocate. The microneedle mechanism can repeatedly puncture the skin of the head, thereby piercing the skin and supplying medication.
[0027] The microneedle mechanism includes a microneedle housing 109, which comprises an upper first mounting cavity and a larger lower second mounting cavity. A piston is disposed within the second mounting cavity, and a push rod 108 is disposed within the first mounting cavity. The push rod 108 is connected to the piston, and the reciprocating motion of the push rod 108 causes the piston to reciprocate within the second mounting cavity. A drive handle 107 is connected to the end of the push rod 108, which is connected to one end of a connecting rod 106 of a drive mechanism. A microneedle fixing plate 1011 is connected to the bottom of the piston, and multiple microneedles 1012 are disposed on the microneedle fixing plate 1011. The length of the microneedles 1012 extending beyond the microneedle fixing plate 1011 is 0.5-1 mm, or 0.2-1.5 mm, depending on the specific needs of different populations. The microneedles 1012 are made of silicon, silicon oxide, or stainless steel, and this material structure has certain antibacterial properties and structural strength. The surface of the microneedle 1012 is coated with titanium nitride to improve the wear resistance, friction resistance and corrosion resistance of the microneedle, while maintaining the overall performance of the substrate.
[0028] A spring mounting cavity 1092 is also formed between the first mounting cavity and the push rod 108. A spring 1010 is installed in the spring mounting cavity 1092 and sleeved on the push rod. The spring 1010 can play a buffering role and also play a role in restoring the reciprocating motion.
[0029] The drive mechanism includes a motor 11, an eccentric wheel 102, a mounting housing 103, a slider 104, a lever 105, and a connecting rod 106. The eccentric wheel 102 is connected to the drive end of the motor 11. The mounting housing 103 is installed on the drive end side of the motor 11. The slider 104 is slidably installed inside the mounting housing 103. The eccentric wheel 102 is connected to a drive block 1021. The drive block 1021 extends into the drive groove inside the slider 104. The slider 104 is engaged with one side of the lever 105. The lever 105 is rotatably installed on the mounting housing 103 through the middle lever mounting rod 1051. One end of the lever 105 is connected to one end of the connecting rod 106.
[0030] The slider 104 has slider clips 1041 on both sides, and the mounting shell 103 has two slots for mounting the slider clips 1041, and the distance between the two slots is greater than the distance between the two slider clips 1041.
[0031] The lever 105 has a groove-shaped lever connection part 1052 on the side opposite to the slider 104, and the slider 104 has a slider drive head 1042 on the side opposite to the lever 105. The slider drive head 1042 is connected to the lever connection part 1052.
[0032] One end of the lever 105 is provided with a lever mounting rod 2 1053, which is connected to one end of the connecting rod 106.
[0033] In the drive mechanism, the eccentric wheel 102 is rotated by the motor 11, which in turn drives the drive block 1021 to rotate eccentrically. Since the slider 104 is laterally slidably installed in the mounting shell 103, the movement of the drive block 1021 can drive the slider 104 to move laterally reciprocally in the mounting shell 103. The reciprocating movement of the slider 104 thus drives the slider drive head 1042 to move reciprocally, which in turn drives the lever 105 to swing along the lever mounting rod 1051, which in turn drives the lever mounting rod 1053 to move up and down reciprocally, thereby realizing the reciprocating movement of the piston.
[0034] The device specifically includes a pump body 201, which is a common infusion pump body. The output end of the pump body 201 is connected to the bottom of the drug reservoir 203 through a first connecting pipe 202. The drug reservoir 203 has a storage space for storing the drug solution for injection. The bottom of the drug reservoir 203 is connected to the upper part of the dispenser 205 through a second connecting pipe 204. The bottom of the dispenser 205 is connected to multiple delivery pipes 206. The ends of the delivery pipes 206 are connected to nozzles 207. The nozzles 207 are installed on the mounting plate 101 of the drug administration spray system 100. The nozzles 207 are nozzles that can spray the drug solution. The nozzles 207 generally have multiple spray holes.
[0035] The mounting plate 101 is provided with a spray mounting hole 1013. The nozzle 207 is installed into the spray mounting hole 1013. The spray mounting hole 1013 can be round, or it can be set to an ellipse, triangle, square or other arbitrary shapes. You only need to set the outer shell of the nozzle 207 to the corresponding shape. Specifically, it can be fixed by glue during installation.
[0036] The mounting plate 101 is circular, and the spray mounting holes 1013 are arranged in a circumferential array on the mounting plate 101. The number of spray mounting holes 1013 is 3, 4, 5, 6, 7, or 8. The spray mounting holes 1013 can also be arranged in multiple circumferential arrays, such as two circumferential distributions, that is, an inner ring of spray mounting holes 1013 and an outer ring of spray mounting holes 1013.
[0037] The medicine storage container 203 is equipped with a medicine inlet, which is a door or one-way valve with a sealing strip on the medicine storage container 203. The medicine inlet is used to inject the medicine for increasing the volume of the medicine into the container.
[0038] The mounting plate 101 is also equipped with a microneedle stimulation unit 1, which is used to perform microneedle acupuncture on the head area after the medicine is sprayed, so as to facilitate the medicine to penetrate into the scalp.
[0039] The specific microneedle stimulation unit is installed onto the drug delivery spray system 100 through the threaded port 1091 on the microneedle housing 109.
[0040] The working principle of this device is as follows: This device involves filling the reservoir 203 with liquid medicine, then pressurizing and delivering the liquid medicine through the pump 201. The liquid medicine enters the distributor through the second connecting pipe, and after passing through the distributor, the liquid medicine enters the delivery pipe evenly. Then, it is sprayed onto the scalp where hair growth is needed through the nozzle, and works in conjunction with the microneedle stimulation unit.
[0041] In the microneedle stimulation unit, the rotation of the eccentric wheel is driven by a motor, which drives the reciprocating motion of the piston after mechanical transmission, thereby realizing the reciprocating motion of the microneedle. It can puncture the skin of the patient's head, and after puncture, the drug spraying unit can spray the drug solution.
[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
