Problems solved by technology

The newly developed microneedle injection in recent years also affects the treatment effect of the lesion due to the limited depth of drug injection.
[0003] In recent years, the injection transdermal drug delivery devices sold on the market have the following technical problems: the needle of the traditional syringe cannot be adjusted, therefore, the treatment can only be performed at a certain depth of the lesion when injecting the drug, thus limiting the range of treatment ; Second, traditional syringes can only be injected one by one, which not only treats a small area, but also wastes a lot of time, prolonging the pain of the patient
These two problems greatly reduce the scope of application of this type of syringe, therefore, the syringe in the prior art is difficult to popularize and apply in the market
[0004] The injection drug delivery devices currently on the market not only have a small treatment area and high treatment costs, but also prolong the pain of the patient. This type of device is difficult to promote and apply. drug delivery device

Embodiment 1

[0024] Such as figure 1 As shown, an adjustable transdermal drug delivery device includes a drainage tube, a negative pressure device connected to one end of the drainage tube and an injection needle 1 connected to the other end of the drainage tube, and the injection needle 1 includes a The tube body 3 of the negative pressure interface 2, the adjustment knob 5 connected to one end of the tube body 3 and with the connecting part 4 extending into the tube body, and the needle holder 6 sleeved in the tube body 3 and fixedly connected with the connecting part 4 , the adjustment knob 5 can change the position of the needle holder 6 in the tube body 3, the connecting part 4 and the needle holder 6 are provided with a plurality of through holes passing through them, and the through holes on the connecting part 4 are connected with the needle The through hole on the seat 6 is connected, and a plurality of needles 7 are inserted in the through hole on the needle seat 6, and the end o...

Embodiment 2

[0033] The difference between this embodiment and Embodiment 1 is that the distance between adjacent side holes 8 is 0.2 mm.

Embodiment 3

[0035] The difference between this embodiment and Embodiment 1 is that the distance between adjacent side holes 8 is 0.3 mm.

[0036] The use process of the adjustable transdermal drug delivery device in the present invention is as follows: before use, first connect the negative pressure device to one end of the drainage tube, connect the other end of the drainage tube to the negative pressure interface 2 on the injection needle 1, Then connect the syringe with the liquid medicine to the end away from the needle; when in use, first turn the adjusting knob 5 to change the position of the needle seat 6 in the tube body 3, so that the needle 7 reaches the required length, and the needle 7 is vertical Insert into the lesion so that the nozzle of the tube body 3 is close to the skin of the human body, activate the negative pressure device, and push the liquid medicine to the lesion, at this time, the negative pressure attracts the cell membrane of the skin, causing it to expand and ...

Abstract

The invention discloses an adjustable transdermal administration device and a using method thereof, and belongs to the technical field of transdermal administration. A syringe needle comprises a pipe body with a negative pressure port, an adjusting rotary knob and a needle base, wherein the adjusting rotary knob is connected to one end of the pipe body and provided with a connecting part stretching into the pipe body, and the needle base is sleeved with the pipe body and fixedly connected with the connecting part; multiple through holes are formed in the connecting part and the needle base respectively and penetrate through the connecting part and the needle base, the through holes in the connecting part are communicated with the through holes in the needle base, multiple needles are inserted in the through holes in the needle base, and the end, away from one end of the pipe body, of the adjusting rotary knob is connected with a syringe. The using method includes the following steps that one end of a connecting pipe is connected with a negative pressure device, the other end of the connecting pipe is connected with the negative pressure port, the syringe with absorbed liquid medicine is connected to one needle; the length of the needle is adjusted, and the needle obtained after adjustment punctures the focus; the negative pressure device is started, and the syringe is slightly pushed. The adjustable transdermal administration device can meet the treatment requirements for different depths in clinic treatment and has the advantages of being simple in structure and high in applicability.

Description

technical field [0001] The invention relates to the technical field of transdermal drug delivery, in particular to an adjustable transdermal drug delivery device and a usage method thereof. Background technique [0002] Transdermal drug delivery is a type of drug delivery method that passes through the skin through a special device and enters local tissues or the circulatory system to achieve disease prevention or treatment. Transdermal drug delivery devices are most common in burn plastic surgery, because most patients have large scars and thick scars. If traditional transdermal drug delivery methods are used, only a certain amount of drugs can be injected in one injection. Due to the control of the total amount of drugs, Therefore, the area to be treated is limited. The newly developed microneedle injection in recent years also affects the treatment effect of the lesion due to the limited depth of drug injection. [0003] In recent years, the injection transdermal drug d...
