Example two:
a transdermal patch special for short and small children in western high-altitude areas is basically the same as the first embodiment in that 2 upright posts 10 penetrate through the top and the bottom of a fixing plate 2 and are in sliding connection with the fixing plate 2 at the penetrating positions, pressing blocks 14 are arranged at the bottoms of the upright posts 10, and sucking discs 16 are arranged on two sides, close to each other, of negative pressure sponge layers 17, as shown in figures 2 and 3. The negative pressure sponge layer 17 is internally provided with a hose 18, one end of the hose 18 is connected with the suction cup 16, and the other end of the hose 18 penetrates through the side surface of the application main body 1 and forms a liquid inlet hole 24 at the penetrating position.
The bottoms of the columns 10 on both sides of the needle cylinder 15 penetrate the top and bottom of the fixing plate 2 and are connected with the fixing plate 2 in a sliding way at the penetrating position. The bottoms of the 2 upright posts 10 are respectively provided with a pressing block 14, and the pressing blocks 14 extrude sucking discs 16 arranged at two sides of the negative pressure sponge layer 17 which are close to each other, so that the sucking discs and the punctured positions of the skin are further fixed. The inside of negative pressure sponge layer 17 is equipped with hose 18, and the one end and the sucking disc 16 of hose 18 are connected, and the other end runs through the side of applying ointment or plaster main part 1 and forms feed liquor hole 24 in the department of running through, pours into a small amount of liquid (water) into to sucking disc 16 through feed liquor hole 24, seals feed liquor hole 24 when not using to inject simultaneously, makes sucking disc 16 can be better adsorb on human skin surface. After injection, the suction cup 16 is separated from the skin surface by opening the fluid inlet hole 24. The negative pressure sponge layer 17 is adsorbed with a drug for treating skin disorders caused by the injection of auxin.
The working principle is as follows: during the use, will keep somewhere the needle and fix through cassette 9 joint, keep somewhere the syringe spiral of injection usefulness of needle afterbody connection and place in rail 7, connect outside device (like the syringe) of dosing through the syringe during use and inject, inject through the syringe of the afterbody of keeping somewhere the needle, can realize the operation of injecting many times. The sterilized alcohol is injected into the sterilized cotton 16 through the liquid inlet hole 24. The pressing lever 4 is pressed downward with a force to move the pressing plate 3 downward, and the pressing piece 14 presses the suction cup 16 to further fix the skin by suction near the skin puncture site. The needle point of the remaining needle is punctured into skin, the first clamping piece 12 is clamped with the second clamping piece 23, and auxin is injected. After injection, the push rods 13 at the two sides of the application main body 1 are pushed inwards to separate the first clamping piece 12 from the second clamping piece 23, and the pressing plate 3 moves upwards under the action of the first spring 11 to separate the needle tip of the remaining needle from the skin. Can effectively treat skin diseases generated after the auxin is injected. The transdermal patch can be repeatedly injected for 2-3 times, and can be administered for 3 times per week with the lowest dose of 0.1 U.kg -1 ·d -1 rhGH, maximum dose 0.2 U.kg -1 ·d -1 And (4) injecting rhGH.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
