Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the present invention provides a liquid medicine introducing head 100, which includes: a lead-in head body 1 and a nano-wafer 2.
The introduction head body 1 is hollow, so that the introduction head body 1 can be used as a storage container for liquid medicine. The end face of one end of the leading-in head body 1 forms a working face. In order to facilitate liquid discharge, correspondingly, the working surface is provided with a liquid discharge hole 11 communicated with the interior of the leading-in head body 1. Thus, when the liquid medicine is stored in the inlet head body 1, the liquid medicine can flow out from the liquid outlet hole 11 to supply the liquid medicine. In one embodiment, the number of the liquid outlet holes 11 is multiple, and the plurality of liquid outlet holes 11 are distributed around the nano-chip 2, so as to achieve uniform supply of the drug.
In the molding mode, the lead-in head body 1 is integrally molded by injection molding. In one embodiment, the introduction head body 1 is made of a light-shielding material, so as to prevent the chemical liquid stored in the introduction head body 1 from changing its properties.
The nano-wafer 2 comprises a base and micro-needles arranged on the base.
The nanometer wafer 2 is a nanometer permeation promoting special tool developed according to the structure of human skin, and is formed by carving monocrystalline silicon through a nanometer technology process. The surface of the nanometer chip is a series of micro-needles arranged in an array, which can open the outermost horny layer of the skin without hurting the dermis layer, thus greatly improving the permeability of the drug.
The nanometer wafer 2 is directly embedded into a mounting groove formed when the leading-in head body 1 is injected, and the micro-needle on the nanometer wafer 2 extends to the working surface. At this time, the surface of the nano-wafer 2 in contact with the introduction head body 1 and the introduction head body 1 can be penetrated and bonded to each other more firmly. Therefore, the combination of the mode of gluing and the leading-in head body 1 is avoided, the defect of gluing mode fixing is overcome, and the assembly and the fixing of the nano wafer 2 are facilitated.
In order to achieve the interpenetration between the nano-wafer 2 and the lead-in head body 1, the nano-wafer 2 is synchronously embedded into the working surface of the lead-in head body 1 when the lead-in head body 1 is injection molded. Alternatively, the nano-wafer 2 may be embedded in the working surface of the lead-in head body 1 after the lead-in head body 1 is injection molded and before being cured. In the two assembling modes, because the leading-in head body 1 is not completely cured and molded and the temperature of the leading-in head body 1 is higher, the surfaces of the nano wafer 2 and the leading-in head body 1 which are contacted can be mutually permeated and fused, and firm combination is realized.
In order to protect the nano-chip 2 and the working surface and prevent the liquid medicine stored in the introduction head body 1 from leaking, a protective cover 3 is further installed at one end of the introduction head body 1, and the nano-chip 2 and the working surface are accommodated in a space defined by the protective cover 3. At this time, one side of the protective cover 3 opposite to the working surface is pressed on the liquid outlet 11, and correspondingly, one side of the protective cover 3 opposite to the working surface is further provided with an accommodating cavity for accommodating the extended nano-chip 2.
In order to fix the protective cover 3, in one embodiment, an external thread is provided on an outer peripheral wall surface of one end of the introduction head body 1, and the protective cover 3 is screwed to one end of the introduction head body 1 through the external thread. In other embodiments, the introduction head body 1 may be sleeved on one end of the introduction head body 1 by a snap-fit manner.
As shown in fig. 2, based on the liquid medicine introducing head 100, the present invention further provides a penetration enhancer 200 using the liquid medicine introducing head 100. Specifically, the penetration enhancer 200 includes: a housing 201, and the above-described drug solution introducing head 100 attached to the administration end of the housing 201.
In order to facilitate the connection and fixation between the housing 201 and the liquid medicine introducing head 100, a clamping structure 12 is further disposed on the circumferential outer side wall of the introducing head body 1, and the clamping structure 12 is a protrusion or a recess disposed on the outer side wall. When the fastening structure 12 is a protrusion disposed on the outer sidewall, a corresponding position in the inner cavity of the administration end of the housing 201 is provided with a fastening groove matched with the protrusion; when the engaging structure 12 is a recess disposed on the outer sidewall, a corresponding position in the inner cavity of the administration end of the housing 201 is provided with a buckle matched with the protrusion. Thus, after the liquid medicine introducing head 100 is used, the liquid medicine introducing head 100 can be taken down and discarded, and a new liquid medicine introducing head 100 is replaced, so that the use of a user is facilitated.
To sum up, the utility model discloses a nanometer wafer directly imbeds on leading-in head body working face in the leading-in head of liquid medicine, its mode of having avoided passing through the viscose combines together with leading-in head body, has overcome the defect when viscose mode is fixed, has made things convenient for nanometer wafer's equipment fixed.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
