Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

The present application provides an applicator device, as shown in fig. 1-4, comprising:

a cylindrical housing 1;

a moving mechanism 3 mounted in the cylindrical housing 1, the moving mechanism 3 including an impact hammer 34, the impact hammer 34 being provided so as to be capable of reciprocating in a longitudinal direction of the cylindrical housing 1;

the medicine bin 2 is used for containing fluid medicines and is arranged at one end of the cylindrical shell 1, a contact part used for contacting a nursing part is arranged on the medicine bin 2, and at least one medicine outlet 211 is arranged on the contact part;

when the contact portion contacts the nursing position, the impact hammer 34 reciprocates toward and away from the nursing position, so that the medicine in the medicine bin 2 can overflow from the medicine outlet 21 to be smeared on the nursing position under the excitation of the impact hammer 34.

When the contact portion of the medicine applying device provided by the application is used for applying medicine to a nursing position, the impact hammer reciprocates, and the reciprocating motion of the impact hammer can not only excite medicine to be applied from the medicine outlet hole, but also can help the skin to absorb the medicine due to excitation of the impact hammer to the nursing position, so that the nursing effect is improved. And the difference of the medicine smearing effects caused by different people in treatment can be weakened by adopting the impact hammer under the impact vibration of fixed impact frequency, so as to achieve the basically uniform treatment effect.

Optionally, the contact portion for contacting the care site is made of a flexible material, such as silicone.

Optionally, an end of the drug outlet 211 facing the skin is formed in a horn shape.

The contact portion is made of flexible material, or the medicine outlet hole 211 is made of horn shape, so that when the contact portion contacts with skin, sucking disc effect is generated, under the action of the impact hammer 34, the skin vibrates up and down, and the medicine outlet hole 211 has sucking effect relative to the skin, so that kinetic energy is generated to suck medicine from inside to outside and apply the medicine to the skin. Similarly, the sucking effect can generate sucking force from outside to inside to the skin, so that pores of the skin can be opened and spread, the exchange of substances inside and outside the skin is facilitated, and the absorption of medicines is promoted.

In addition, the size of the medicine outlet hole 211 may be set according to the type of medicine, for example, when the medicine in the medicine cartridge 2 is a thick paste-like medicine, the medicine outlet hole 211 may be set to have a relatively large pore size so that the medicine can flow out of the medicine outlet hole 211 at an appropriate flow rate during vibration. While for fluid-like drugs, the drug outlet holes 211 may have smaller pore diameters, which may be set as: in the non-operating state of the impact hammer 34, fluid medicine cannot flow out of the medicine outlet hole 211 under the action of surface tension, and medicine can flow out of the medicine outlet hole 211 under the action of the movement impact of the impact hammer 34.

The medicine dispensing device with the medicine dispensing hole 211 with a proper aperture can be selected for the used medicine, or a plurality of different contact parts (or different medicine bins) can be arranged corresponding to one medicine dispensing device, and the proper contact parts or the whole medicine bin 2 can be replaced for different medicines.

In an embodiment in which the impact hammer 34 is configured to extend from the contact portion and retract from the contact portion to reciprocate, the impact hammer 34 mainly plays a role of striking a care site, but naturally plays a role of vibration, and when the contact portion contacts the skin, the impact hammer 34 reciprocates to strike the skin, thereby promoting absorption of the medicine by the skin and promoting overflowing of the medicine from the medicine outlet hole 211.

In one embodiment, the hammer 34 reciprocates within the range defined by the outer surface of the contact portion, i.e., the amplitude of the reciprocating motion of the hammer 34 does not exceed the contact portion, at which time the hammer 34 primarily vibrates, causing vibration of the entire applicator and the contacted care site, thereby promoting the escape of the drug from the drug exit orifice 211 and absorption of the drug by the skin.

In one embodiment, the medicine compartment 2 has an annular structure with an annular cavity, wherein one end of the medicine compartment 2 forms the contact part with the medicine outlet 211; the impact hammer 34 is arranged to extend into the central bore of the cartridge 2 for reciprocating movement.

Alternatively, as shown in fig. 2, the cartridge 2 includes an annular housing 22 having an annular cavity and being open at one end, and a cover 21 for covering the opening. A plurality of medicine outlet holes 211 are arranged on the cover 21, and the cover 21 forms the contact portion. The medicine outlet hole 211 may be disposed along a circumferential direction of the cover 21, the cover 21 may be connected to the annular housing 22 by means of a snap fit and a snap fit, or a thread may be disposed at a portion where the cover 21 and the annular housing 22 are abutted, and the cover 21 may be connected to the annular housing 22 by means of a threaded connection.

When in installation, the medicine to be smeared can be filled into the annular cavity of the annular shell 22, and the cover body 21 is covered, so that after the medicine is sealed in the annular cavity, the medicine bin 2 is installed on the cylindrical shell 1, or the medicine can be directly poured into the annular shell 22 installed on the cylindrical shell 1, and then the cover body 21 is covered on the opening of the annular shell 22.

When the treatment site is applied around the contact portion of the impact hammer 34, the impact hammer 34 located at the center reciprocates at the center, and vibration of the skin and the applicator and sucking effect of the drug outlet hole can cause the drug to overflow from the drug outlet hole 211 so that the drug is smeared on the skin, and the impact of the impact hammer 34 can also help the skin absorb and permeate the drug.

It will be appreciated by those skilled in the art that the applicator device provided herein may be structurally modified in various ways, for example, the opening of the cartridge 2 for the charge may be provided in the sidewall, so that the outlet opening 211 of the cartridge 2 is not provided in the cap 2 covering the opening, and thus the cap 2 is not a contact portion having the outlet opening 211, which is the end face of the cartridge for facing the skin side. The contact portion having the medicine discharge hole 211 is not limited to being provided around the impact hammer 34, and for example, the impact hammer 34 and the contact portion may be provided in parallel, and the impact hammer 34 may reciprocate on one side of the contact portion.

In one embodiment, as shown in fig. 4 and 5, the movement mechanism 3 further includes a driving mechanism for driving the impact hammer 34 to reciprocate, and the driving mechanism includes a motor 31, a cam 32, and a crank link 33.

Wherein, the motor 31 is installed in the tubular housing 1, the cam 32 is driven to rotate by the motor 31, one end of the crank link 33 is rotatably connected to a position of the cam 32 deviating from the rotation center, the impact hammer 34 is rotatably connected to the other end of the crank link 33, and when the motor 31 drives the cam 32 to rotate, the crank link 33 drives the impact hammer 34 to reciprocate.

Further, a battery compartment for mounting the battery 5 may be provided in the cylindrical housing 1, and a switch 6 may be provided in the cylindrical housing 1. The motor 31, the battery 5 and the switch 6 form a series circuit to control the start and stop of the motor 31 by the switch, thereby controlling the movement of the impact hammer 34.

For easy installation, the cylindrical casing 1 may be configured as two halves of a casing, in which an installation structure is disposed inside one half of the casing, for example, a slot capable of being clamped with the motor 31 or an installation hole for installing the motor 31, and a slot for clamping the battery 5 are disposed, and after the battery 5, the motor 31, the cam 32, the crank link 33, and the impact hammer 34 are mounted on the one half of the casing, the two halves of the casing are assembled.

Alternatively, as shown in fig. 5, the tip of the impact hammer 34 for contacting the skin is provided in a circular configuration, although other shapes are possible.

In one embodiment, the distal surface of the hammer 34 for contacting the skin is provided as a convex surface, and the hammer 34 having a convex surface is suitable for striking muscular tissue, and also suitable for striking a concave portion of a nursing site, particularly an acupoint or the like.

In one embodiment, the surface of the impact hammer 34 for contacting the skin may be provided as a concave surface, and the impact hammer 34 having a concave surface is adapted to strike the knee joint, elbow joint, or the like.

In one embodiment, the hammer 34 is made of a flexible material, which may be, for example, silicone, and the hammer 34 is adapted to strike a joint or bone.

In one embodiment, the hammer 34 is made of a rigid material, and the rigid material of the hammer 34 is suitable for striking muscle tissue.

For different nursing positions, an application device with a proper impact hammer 34 can be selected, a plurality of different impact hammers 34 can be arranged corresponding to one application device, and the proper impact hammer 34 is assembled for different nursing positions.

In some embodiments, the impact hammer 34 is configured to extend from the contact portion and retract from the contact portion to reciprocate, thereby delivering the drug to the care site while striking the care site to facilitate drug absorption.

However, the impact hammer 34 is not suitable for striking with the same striking strength for different medicines or different degrees of patients, and the striking strength of the impact hammer 34, specifically, the extension of the impact hammer 34 with respect to the contact portion is set to be adjustable according to the different permeabilities of medicines, different flowability, different dosage forms, the degree of patients at the affected part, and the like.

For example, in the case of bursitis under the patellar skin, the Qingpeng ointment may be applied to the patellar skin according to the prescription of the doctor, and because of the poor permeability and fluidity of the Qingpeng ointment compared to the aqueous medicine, the impact hammer 34 may be adjusted to have a larger extension to generate a larger impact strength to promote the penetration of the medicine into the skin.

In the case of patella injury, the patella surrounding skin is coated with the osteogenic water according to the doctor prescription, and the patella injury is not easy to use with a larger impact quantity due to the good fluidity and permeability of the osteogenic water, so that the impact hammer 34 can be adjusted to have a smaller extension amplitude, thereby generating a smaller impact strength to promote the drug to permeate into the skin.

In the embodiment shown in fig. 1 to 4, the movement mechanism 3 is mounted in the cylindrical housing 1, and the first connecting portion 11 is used for mounting the medicine cartridge 2 of an annular structure. Wherein the position of the medicine compartment 2 relative to the first connecting portion 11 is adjustable, so that the extension of the impact hammer 34 relative to the cylindrical housing 1 is adjustable. That is, the position of the medicine cartridge 2 relative to the cylindrical housing 1 is adjusted by using the medicine cartridge 2 as a stopper, so that the extent to which the impact hammer 34 can extend out of the medicine cartridge 2 can be changed, and the striking strength of the impact hammer 34 can be adjusted.

Optionally, an internal thread 23 is provided on the inner surface of the cartridge 2 facing the central hole, and an external thread for mating with said internal thread 23 is provided on the first connection portion 11, and the cartridge 2 adjusts the extension of the impact hammer 34 relative to said contact portion by adjusting the threaded connection position on the first connection portion 11.

Alternatively, a clamping structure positioned at different positions can be arranged between the medicine bin 2 and the first connecting portion 11, and the extension amplitude of the impact hammer 34 relative to the contact portion can be adjusted by adjusting the clamping position of the medicine bin 2 on the first connecting portion 11.

In the embodiment shown in fig. 6, the drug cartridge 2 is connected to the first connection portion 11 by means of a threaded connection, and when the drug cartridge 2 is screwed to be at the first limit position (when the limit distance between the drug cartridge 2 and the cylindrical housing 1 is h1 as shown in the drawing), the drug is administered to the knee portion of the patient by using the drug applicator with reference to fig. 9 and 10, and when the impact hammer 34 is started to strike, the length of the impact hammer 34 that can extend out of the drug cartridge 2 is M1, and at this time, the depth of the skin depression formed by the impact hammer 34 striking the skin is N1.

In the embodiment shown in fig. 7, the drug cartridge 2 is connected to the first connection portion 11 by means of a screw connection, and when the drug cartridge 2 is at the second limit position (when the limit distance between the drug cartridge 2 and the cylindrical housing 1 shown in the drawing is h 2), the drug is administered to the knee portion by using the drug applicator as shown in fig. 11 and 12, and when the impact hammer 34 is activated to strike, the impact hammer 34 can extend beyond the drug cartridge 2 by a length M2, and the depth of the skin depression formed by the impact hammer 34 striking the skin is N2.

Because h2 is greater when the medicine bin 2 is in the second limit position than h1 is in the first limit position, the length M2 of the impact hammer 34 that can extend out of the medicine bin 2 when the medicine bin 2 is in the second limit position is smaller than the length M1 of the impact hammer 34 that can extend out of the medicine bin 2 when the medicine bin 2 is in the first limit position, so that the skin depression depth N2 is smaller than N1, that is, the impact strength of the impact hammer 34 is smaller when the medicine bin 2 is in the second limit position than when the medicine bin 2 is in the first limit position. Thus, by adjusting the connection position of the cartridge 2, the stroke of the impact hammer 34 can be adjusted, thereby adjusting the impact strength of the impact hammer 34 to the care site.

It will be appreciated by those skilled in the art that the impact strength to the hammer 34 is not limited to being changed by changing the position of the cartridge 2, but that the movement mechanism 3 itself may be changed, for example, an adjustment mechanism may be provided on the cylindrical housing 1, which may change the mounting position of the movement mechanism 3, and the extent to which the hammer 34 protrudes from the cartridge 2 may be changed by changing the mounting position of the movement mechanism 3.

In one embodiment, the applicator device further comprises an auxiliary mechanism; the medicine bin 2 is positioned at one end of the cylindrical shell 1, the auxiliary mechanism is arranged at the other end of the cylindrical shell 1, and the auxiliary mechanism is used for smearing medicines and/or stimulating nursing positions.

Optionally, the auxiliary mechanism includes a scraping blade portion 41 and an massaging portion 42, the scraping blade portion 41 being provided for scraping the medicine, and the massaging portion 42 being provided for massaging the care site.

Specifically, as shown in the embodiment of fig. 1 to 4, the end of the cylindrical shell 1 away from the medicine compartment 2 is provided with a second connecting portion 12, the auxiliary mechanism includes a tail shell 4 mounted on the second connecting portion 12, and the scraping blade portion 41 and the massaging portion 42 are integrally formed on the tail shell 4.

The following describes, by way of specific examples, a specific procedure for nursing a patient site using the applicator device provided herein.

The affected part is located at the knee of the human body, as shown in fig. 8, the patella 101 is located at the knee position, the patella 101 is adjacent to the femur 103 of the thigh and the tibia 102 of the calf, respectively, the patella 101 forms a circumferential space around the patella 101 with the femur 103 of the thigh and the tibia 102 of the calf, and a plurality of tiny sliding bags 104 exist in the circumferential space, and the sliding bags 104 are edema causing pain.

Embodiment one:

the ointment of Qingpeng is applied to the peripheral part of the patella 101 by using the applicator shown in fig. 1-4 to treat bursitis, wherein the ointment of Qingpeng belongs to the pasty medicine A with poor permeability and fluidity.

Firstly, the paste medicine a is put into the annular shell 22 from one end opening, then the cover 21 is covered to complete the closing of the medicine bin 2, the medicine bin 2 is rotated relative to the first connecting part 11 of the cylindrical shell 11 to make the first limiting distance between the medicine bin 2 and the first connecting part be h1, as shown in fig. 6 and 9, wherein the limiting distance is calibrated by taking the length between the medicine bin 2 and the main body part of the cylindrical shell 1 as a calibration, and the limiting distance can be calibrated by other distances, for example, the distance between the medicine bin 2 and the tail end of the cylindrical shell 1, as long as the position change of the medicine bin 2 relative to the cylindrical shell 1 can be represented.

When the first limit distance is h1, as shown in fig. 10, the impact mechanism 3 is started, and the impact hammer 34 can extend out of the medicine compartment 2 by a length M1 at the time of the maximum working stroke, and when striking the skin, the depth of the skin depression is made to be N1.

In application, the applicator is placed on the skin at the knee, as shown in fig. 9 and 10, the cap 21 with the drug outlet 211 is in contact with the skin, the switch 6 is actuated, the motor 31 rotates to drive the impact hammer 34 to reciprocate through the cam 32 and the crank link 33, and impact vibration is performed on the skin at the knee. On the other hand, the pasty medicine A in the medicine bin 2 flows out of the medicine outlet 211 under the action of impact vibration and is coated on the skin; on the other hand, the energy efficiency generated by the impact vibration can improve the absorption of the skin to the ointment-like medicine A, and meanwhile, the impact hammer 34 can impact the sliding bag 104 around the patella 101, so that the treatment effect can be improved.

For the junction between the patella 101 and the tibia 102, because the bone structure can affect the even application of the medicine at the junction, after the paste medicine a is applied, as shown in fig. 13, the skin at the junction is relatively concave, and the doctor blade 41 on the tail housing 4 can be used to scrape the skin at the junction, so as to massage the skin at the junction, thereby achieving a better medicine absorption effect.

For the junction between the patella 101 and the femur 103, since the protrusion of the bone structure affects the even application of the medicine at the junction, after the paste medicine a is applied, as shown in fig. 14, the skin at the junction is relatively small in concave area, and the kneading portion 42 on the tail housing 4 can be used to knead the skin at the junction, thereby helping the absorption of the medicine and achieving a better medicine absorption effect.

In addition, the scraping blade 41 may be used as a scraping plate, and the knee part may be massaged by scraping.

Embodiment two:

the application device shown in fig. 1-4 is used to apply bone setting water to the surrounding area of the patella 101, wherein the bone setting water belongs to fluid medicine B with better permeability and fluidity.

First, the fluid medicine B is put into the annular housing 22 from one end opening, and then the cap 21 is covered to complete the closing of the medicine cartridge 2, and the medicine cartridge 2 is rotated relative to the first connecting portion 11 of the cylindrical housing 1 so that the second spacing distance therebetween is h2, as shown in fig. 7 and 11.

At the second limit distance h2, as shown in fig. 12, the impact hammer 34 can extend out of the medicine cartridge 2 by a length M2 at the maximum working stroke, and when striking the skin, it makes the depth of the skin depression N2.

In use, the applicator is placed on the skin at the knee, as shown in fig. 11 and 12, with the cap 21 having the dispensing orifice 211 in contact with the skin. The switch 6 is started, the motor 31 rotates to drive the impact hammer 34 to reciprocate through the cam 32 and the crank connecting rod 33, and impact vibration is carried out on the skin at the knee part. On the other hand, the fluid medicine B in the medicine bin 2 flows out from the medicine outlet 211 to be coated on the skin under the impact vibration effect; on the other hand, the energy efficiency generated by the impact vibration can improve the absorption of the fluid medicine B, and meanwhile, the impact hammer 34 can impact the sliding bag 104 around the patella 101, so that the treatment effect can be improved.

Wherein, for the junction position of the patella 101 and the tibia 102, after the medicine is smeared, the doctor blade part 41 on the tail shell 4 can be adopted to scrape the skin at the part, and the part can be massaged; for the junction between the patella 101 and the femur 103, after the medicine is applied, the skin at the junction can be rubbed by the massaging part 42 on the tail shell 4 to help the medicine absorption, so as to achieve better medicine absorption effect.

In addition, the scraping blade 41 may be used as a scraping plate, and the knee part may be massaged by scraping.

It should be noted that, in the second embodiment, the second limiting distance h2 is greater than the first limiting distance h1 in the first embodiment, so that the length M2 of the impact hammer 34 in the second embodiment that can extend out of the drug compartment during operation is smaller than the extending length M1 of the impact hammer 34 in the first embodiment, that is, the impact strength of the impact hammer 34 in the second embodiment is smaller than the impact strength of the impact hammer 34 in the first embodiment.

In the first embodiment, the paste-like drug a having poor flowability and poor permeability is used, and therefore, the drug absorption is promoted by using a large impact strength, whereas in the second embodiment, the fluid drug B having good flowability and permeability is used, and therefore, a small impact strength is used.

In addition, since the drug used in the second embodiment is the fluid drug B having a relatively good fluidity, and the drug used in the first embodiment is the paste drug a having a relatively poor fluidity, the aperture of the drug outlet hole 211 of the drug applicator used in the first embodiment is larger than the aperture of the drug outlet hole 211 of the drug applicator used in the second embodiment.

Preferred embodiments of the present application have been described in detail above with reference to the accompanying drawings, but the present application is not limited thereto. Within the scope of the technical idea of the present application, a number of simple variants of the technical solution of the present application are possible, including the combination of the individual specific technical features in any suitable way. In order to avoid unnecessary repetition, the various possible combinations are not described further.
