Description

Technical Field

[0001] The utility model relates to the technical field of microneedles, in particular to a microneedle patch introduction device. Background Art

[0002] In the current medical and beauty fields, microneedle technology has attracted widespread attention due to its ability to accurately and minimally invasively introduce drugs or active ingredients into the deep layers of the skin. However, existing microneedle patches usually rely on manual pressing, which has many influencing factors.

[0003] First, different users have different grasps of the pressure, which may lead to inconsistent penetration depth of the microneedles and affect the drug delivery effect of the microneedles. If the pressure is insufficient, the microneedles may not be able to fully penetrate the skin, thus affecting the absorption of the drug; conversely, if the pressure is too great, it may increase the patient's pain or affect the microneedle structure of the microneedle patch, causing deformation and breakage.

[0004] Secondly, the angle of the microneedle when pressed manually is also a factor that is difficult to control. Due to the unevenness and softness of the human skin surface, it is difficult to ensure that the microneedle penetrates the skin at a constant angle. Angle deviation will not only affect the structural stability and insertion safety of the microneedle, but may also affect the distribution and effect of the drug.

[0005] In order to solve the problem of unstable drug introduction caused by pressing with hands, which affects the drug administration effect, the prior art provides a microneedle introduction instrument such as CN105073180B, which only achieves a single introduction effect. However, due to the different tightness of the skin in different parts, the drug administration stability problem cannot be completely solved when the drug is administered. In order to completely solve the problem of stable drug administration, the prior art provides an introduction instrument such as WO2021121589A1 that introduces a microneedle patch after stretching the skin. It is equipped with a spring and a variety of contact and fastening components to achieve microneedle introduction. The structure is complex and the processing cost is high, which increases the cost investment of public medical care and also increases the cost of medication for patients. Utility Model Content

[0011] Wherein, a flange protrudes outward from the edge of the introduction member, and the abutting member can abut against one side of the flange close to the adsorption surface;

[0012] When pressure is applied to the adsorption mechanism from the adsorption member toward the adsorption surface, the flange can deform or break the abutting member.

[0013] In some embodiments of the present invention, a plurality of guiding grooves are axially formed on the inner side wall of the sleeve member, and a sliding block corresponding to the guiding groove extends outward from the flange.

[0014] In some embodiments of the present invention, the abutting member includes a ring body and an abutting block, and the abutting block is disposed on the inner side wall of the ring body;

[0015] A through hole corresponding to the abutting block is formed on the peripheral side of the sleeve member. The ring body is sleeved on the outer peripheral side of the sleeve member and the abutting block is fitted into the through hole, and the abutting block extends out from the inner side of the sleeve member for abutting against the flange.

[0017] In some embodiments of the present invention, a receiving cavity is formed on the side of the introduction member away from the adsorption surface, and the adsorption member is fitted into the receiving cavity.

[0018] In some embodiments of the present invention, a groove is formed on the side surface of the introduction member in the receiving cavity, and a kneading portion corresponding to the groove protrudes from the side surface of the adsorption member relative to the receiving cavity.

[0019] In some embodiments of the present utility model, the support arm and the positioning sleeve are hingedly arranged, and an elastic member for providing bending and resetting is arranged at the hinged position of the support arm and the positioning sleeve.

[0020] In some embodiments of the present invention, a first limiting member is protruding outwardly from the peripheral side of the sleeve member, and the first limiting member can abut against the positioning sleeve.

[0021] In some embodiments of the present invention, a second limiting member protruding from the inside is provided on a side of the sleeve member away from the positioning sleeve, and the second limiting member is used to abut against a side of the flange away from the adsorption surface.

[0022] In some embodiments of the present invention, one end of the support arm away from the positioning sleeve is coated with a flexible material.

[0023] The technical scheme of the utility model absorbs and positions the microneedle patch with ferromagnetic elements on the absorption surface, and embeds the absorption mechanism in the sleeve part, and abuts against the side of the flange close to the absorption surface through the abutment member, so that the abutment mechanism is positioned in the sleeve part, and the sleeve part is arranged on the positioning sleeve to achieve the positioning and coordination of the abutment mechanism, the absorption mechanism and the stretching mechanism; when the microneedle patch is attached, force is applied from the bottom to the positioning sleeve, so that the support arm is bent outward by the force, so that the skin area attached by the positioning sleeve is stretched and flattened, and the flatness of the skin area attached by the microneedle patch is improved; further force is applied from the bottom to the absorption member, and the flange is moved from the bottom to the support arm, so that the support arm is bent outward by the force, so that the skin area attached by the microneedle patch is stretched and flattened, and the flatness of the skin area attached by the microneedle patch is improved; further force is applied from the bottom to the absorption member, and the flange is moved from the bottom to the support arm, so that the support arm is bent outward by the force, so that the support arm is stretched and flattened outward by the support arm, and the flatness of the skin area attached by the microneedle patch is improved; further force is applied from the bottom to the absorption member, and the flange is moved from the bottom to the support arm, so that the support arm ... Under the action of the force, downward pressure is applied to the abutment piece. When the force exceeds a certain range, the abutment of the flange causes the abutment piece to deform or break. At this time, the flange impacts through the abutment piece from below under the action of the force, driving the adsorption mechanism to move from below, thereby driving the microneedle patch to be introduced and fit the skin under the action of the pressure. Under the premise of ensuring the flatness of the fit to the skin, the abutment piece is used to accumulate force for the fit of the microneedle patch, thereby achieving stable adhesion between the microneedle patch and the skin.

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

If the specific posture changes, the directional indications will also change accordingly.

[0037] In addition, the descriptions involving "first", "second", etc. in the present utility model are only for descriptive purposes, and cannot be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] Refer to the appendix Figures 1-4 , the present utility model provides a microneedle patch introduction device. The microneedle patch introduction device includes an adsorption mechanism 100, a spreading mechanism 200, and an abutting mechanism 300; through the spreading action of the spreading mechanism 200 on the skin, the flatness of the skin is improved, and through the cooperation between the adsorption mechanism 100 and the abutting mechanism 300, the adsorption mechanism 100 can stably apply force to the skin for introduction.

[0039] Among them, the adsorption mechanism 100 includes an introduction member 110 and an adsorption member 120, and the introduction member 110 is detachably connected to the adsorption member 120; the adsorption member 120 is arranged on one side of the introduction member 110, and the adsorption member 120 can provide an adsorption force through the introduction member 110. The other side of the introduction member 110 is an adsorption surface 111 for adsorbing and positioning the microneedle patch 1000; through the adsorption force provided by the adsorption member 120 on the adsorption surface 111, the adsorption effect on the microneedle patch 1000 with ferromagnetic elements is realized. When the adsorption member 120 is disassembled, there is no adsorption force between the microneedle patch 1000 and the adsorption surface 111, and the separation from the adsorption surface 111 is realized. Since the microneedle patch 1000 adheres to the skin, when the adsorption member 120 is separated from the microneedle patch 1000, the microneedle patch 1000 can still be stably embedded in the skin, ensuring the stability of drug delivery.

[0040] Furthermore, the spreading mechanism 200 includes a positioning sleeve 210 and a plurality of support arms 220. The plurality of support arms 220 are arranged at intervals on the circumference of the positioning sleeve 210. One end of the support arm 220 is connected to the circumference of the positioning sleeve 210, and the support arm 220 is arranged at an obtuse angle with the end face of the positioning sleeve 210. The support arm 220 can be bent outward relative to the positioning sleeve 210; through the other end of the support arm 220 to abut against and receive force from the skin and bend outward, the plurality of support arms 220 achieve the spreading and stretching effect on the skin, and can improve the flatness of the skin inside the positioning sleeve 210 within a certain range. It should be noted that the number of support arms 220 can be 2 or more, and no specific limitation is made here. In this embodiment, the number of support arms 220 is 4.

[0041] The abutment mechanism 300 includes a sleeve member 310 and an abutment member 320. The sleeve member 310 is arranged on the positioning sleeve 210. The abutment member 320 is protruded from the inner wall of the sleeve member 310. The adsorption mechanism 100 is embedded in the sleeve member 310 and can move in the sleeve member 310 and the positioning sleeve 210. The skin area facing the positioning sleeve 210 is the attachment area of ​​the microneedle patch 1000. The microneedle patch 1000 is close to the skin through the movement of the adsorption member 120 in the sleeve member 310 and the positioning sleeve 210.

[0042] The edge of the introduction member 110 is provided with a flange 112 protruding outwardly, and the abutment member can abut against a side of the flange 112 close to the adsorption surface 111;

[0043] When pressure is applied to the adsorption mechanism 100 from the adsorption component 120 toward the adsorption surface 111, the flange 112 can deform or break the abutment 320. When the abutment 320 is deformed or broken, the flange 112 can pass through the abutment 320 under the action of the force, thereby achieving the adsorption mechanism 100 driving the microneedle patch 1000 to adhere to the skin.

[0044] The microneedle patch 1000 introduction device based on the above technical features adsorbs and positions the microneedle patch 1000 with ferromagnetic elements on the adsorption surface 111, and the adsorption mechanism 100 is embedded in the sleeve member 310, and the abutment member 320 abuts against the side of the flange 112 close to the adsorption surface 111, so that the abutment mechanism 300 is positioned and arranged in the sleeve member 310, and the sleeve member 310 is arranged on the positioning sleeve 210 to achieve the positioning and coordination of the abutment mechanism 300, the adsorption mechanism 100 and the stretching mechanism 200; when the microneedle patch 1000 is attached, force is applied from below to the positioning sleeve 210, so that the support arm 220 is bent from the outside under the force, so that the skin area to which the positioning sleeve 210 is attached is stretched and flattened, thereby improving the flatness of the skin area to which the microneedle patch 1000 is attached; further, the adsorption member 120 is The flange 112 applies downward pressure toward the abutment 320 under the action of the force applied from below. When the force exceeds a certain range, the abutment of the flange 112 causes the abutment 320 to deform or break. At this time, the flange 112 impacts through the abutment 320 from below under the action of the force, driving the adsorption mechanism 100 to move from below, thereby driving the microneedle patch 1000 to be introduced and fitted to the skin under the action of the pressure. Under the premise of ensuring the flatness of the fitted skin, the abutment 320 is used to store force for the microneedle patch 1000, thereby achieving stable adhesion between the microneedle patch 1000 and the skin. At this time, the adsorption component 120 is separated from the introduction component 110, so that the microneedle patch 1000 and the introduction component 110 are separated, thereby achieving separation between the microneedle introduction device and the microneedle patch 1000.

[0045] Specifically, a plurality of guiding grooves 311 are axially formed in the inner sidewall of the sleeve member 310, and a sliding block 112A corresponding to the guiding grooves 311 extends from the outer side of the flange 112; through the fitting and sliding between the sliding block 112A and the guiding grooves 311, the stable sliding between the guiding member 110 and the sleeve member 310 is realized, and the movement stability between the adsorption mechanism 100 and the abutting mechanism 300 is improved.

[0046] In this embodiment, the abutting member 320 includes a ring body 321 and an abutting block 322, and the abutting block 322 is arranged on the inner sidewall of the ring body 321;

[0047] Wherein, a through hole corresponding to the abutting block 322 is formed in the circumferential side of the sleeve member 310, the ring body 321 is sleeved on the outer circumferential side of the sleeve member 310 and the abutting block 322 is fitted into the through hole, and the abutting block 322 extends out from the inner side of the sleeve member 310 for abutting against the flange 112; by sleeving the ring body 321 on the outer circumferential side of the sleeve member 310, the installation between the abutting member 320 and the sleeve member 310 is realized, and through the corresponding fitting between the through hole and the abutting block 322, the positioning fit between the abutting member 320 and the sleeve member 310 is realized, and further the stable abutting against the flange 112 is realized, so as to avoid dislocation and affect the introduction stability of the microneedle patch 1000.

[0048] Specifically, the material of the abutting member 320 is a flexible polymer material, such as silica gel, rubber or TPU; by abutting the flexible polymer material of the abutting member 320 against the flange 112, under the rigid shearing of the flange 112 on the sleeve member 310, the force breaking of the abutting member 320 can be realized, and further the force passing of the flange 112 in the sleeve member 310 can be realized.

[0049] Further, a receiving cavity is formed on the side of the guiding member 110 away from the adsorption surface 111, and the adsorption member 120 is fitted into the receiving cavity to realize the adsorption force conduction of the adsorption member 120 to the introduction surface, and at the same time realize the separation and removal of the adsorption member 120 from the guiding member 110; wherein, the adsorption member 120 generates an adsorption force by arranging a magnet 122.

[0050] In this embodiment, a groove 113 is formed on the side surface of the guiding member 110 in the receiving cavity, and a kneading portion 121 convex corresponding to the receiving cavity is formed on the side surface of the adsorption member 120 and is fitted into the groove 113. Through the receiving cavity provided with the groove 113, when the user separates the guiding member 110 from the adsorption member 120, the kneading portion 121 can be kneaded and picked up, improving the convenience of the user operation; preferably, there are 2 grooves 113 and they are symmetrically arranged, and there are 2 kneading portions 121 corresponding to the grooves 113, facilitating the user to take out the adsorption member 120 with two fingers and realizing the separation of the microneedle patch 1000 from the adsorption mechanism 100.

[0051] Among them, the support arm 220 and the positioning sleeve 210 are hingedly arranged, and an elastic member for providing bending and restoration is arranged at the hinge position of the support arm 220 and the positioning sleeve 210; so that the support arm 220 has a certain restoration elastic force, and when the skin is stretched, the support arm 220 can be located in the initial position, which is convenient for the user to stretch the skin from the initial position.

[0052] Furthermore, a first stopper 312 is protruded outwardly from the peripheral side of the sleeve member 310 , and the first stopper 312 can abut against the positioning sleeve 210 , so that the sleeve member 310 can be stably placed on the positioning sleeve 210 when subjected to force.

[0053] Specifically, a second limiting member 313 protruding from the inside is provided on the side of the sleeve member 310 away from the positioning sleeve 210. The second limiting member 313 is used to abut against the side of the flange 112 away from the adsorption surface 111 to limit the adsorption mechanism 100 in the sleeve member 310, thereby improving the assembly convenience between the adsorption mechanism 100, the limiting mechanism and the spreading mechanism 200.

[0054] In this embodiment, the end of the support arm 220 away from the positioning sleeve 210 is coated with a flexible material. The flexible material coating improves the user's comfort when the support arm 220 contacts the skin, increases the anti-slip property, and prevents the support arm 220 from causing scratches on the skin.

[0055] The effect of microneedle introduction is shown in the attached Figures 5-7 , Figure 5 This is the microneedle form without introduction and dissolution, and its microneedle structure is clearly visible; Figure 6 For microneedle patches that are introduced using an introduction device that only has an introduction function, the microneedles on the microneedle patch cannot be completely introduced into the skin because the skin is not flattened. Only the needle tip is dissolved, but the needle column is not dissolved, resulting in an unsatisfactory introduction effect; Figure 7 The microneedles of the device introduced by the present technical solution are introduced after the skin is flattened, so that the microneedles can be completely attached to the skin, and the needle tips and needle columns of the microneedle structure are completely dissolved, resulting in a good introduction effect.
