Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of anesthetic application, and particularly relates to an anesthetic application device. BACKGROUND

[0002] The purpose of applying anesthetic on the surface of skin (local surface anesthesia) is to reduce or eliminate the pain of skin and mucous membrane through local drug action, and it is often used for some medical, cosmetic or nursing operations that may cause pain. For example, long-term infusion, blood drawing, insertion of intravenous catheter (especially for children or people sensitive to pain), application of anesthetic can reduce the pain of needle penetration into the skin, or when taking skin tissue for pathological examination, anesthetic can relieve the pain caused by cutting or drilling, or when treating pigment nevus, hemangioma, scar, etc., the laser energy may stimulate the skin, and anesthetic can reduce the burning or stinging sensation, or when removing warts, corns and other skin lesions with liquid nitrogen, anesthetic can reduce the pain caused by low temperature stimulation, or when filling with hyaluronic acid, injecting with botulinum toxin, using water-light needle, etc., the needle penetration into the skin will cause pain, and anesthetic can improve the comfort.

[0003] At present, the common anesthetic application method is to apply anesthetic on the operation area with hands or other relatively hard spatulas after cleaning the skin. This manual application method has the following problems:

[0004] (1) When manually operating, it is difficult to accurately control the thickness of anesthetic, and local over-thickness or under-thickness (i.e. uneven application) may occur, the over-thickness of anesthetic has the risk of excessive absorption, which may cause adverse effects such as dizziness and palpitation, and the under-thickness of anesthetic may cause insufficient analgesic effect. Especially when treating a large area, manual application may cause the total dose to exceed the standard due to estimation error, especially for people with broken skin, the absorption amount of anesthetic through the epidermis increases, which may easily cause poisoning reaction (such as prolonged local numbness and central nervous inhibition).

[0005] (2) Manual application is difficult to control the application amount, therefore, in order to ensure uniform application, careful operation is required, which leads to low operation efficiency, time-consuming and tedious, and significantly prolongs the operation process.

[0006] Therefore, it is necessary to provide an improved technical solution for the above-mentioned deficiencies of the prior art. SUMMARY

[0007] The purpose of the present application is to provide an anesthetic application device to solve the technical problems of uneven application and low operation efficiency of the existing anesthetic application method.

[0008] In order to achieve the above-mentioned purpose, the anesthetic application device of the present application provides the following technical solution:

[0009] A medicine smearing device comprises a body, one end of the body is provided with a connecting unit for detachable connection with a package container containing medicine, the other end of the body is provided with a smearing unit for uniform smearing of medicine, and the body is further provided with a medicine outlet channel for communication between the connecting unit and the smearing unit, which extends to one side of the end of the smearing unit.

[0010] The end of the smearing unit is provided with a uniform smearing mechanism, and when in operation, the medicine squeezed out of the package container containing medicine flows out of the end of the smearing unit through the medicine outlet channel, and the smearing mechanism is used for directly and uniformly smearing the medicine.

[0011] As a further optimized technical solution, the uniform smearing mechanism comprises a smearing plate with a linear or rectangular shape in contact with the skin.

[0012] As a further optimized technical solution, a strip-shaped roller is rotatably arranged at the end of the smearing plate to uniformly smear the medicine.

[0013] As a further optimized technical solution, a limiting groove is arranged at the end of the smearing plate, and the strip-shaped roller is rotatably clamped in the limiting groove, and part of the structure of the strip-shaped roller extends into the end of the medicine outlet channel.

[0014] As a further optimized technical solution, a repeated smearing mechanism is arranged on the body, and the repeated smearing mechanism is arranged on the side of the smearing unit away from the medicine outlet channel, and is used for uniformly smearing the medicine smeared by the smearing unit again.

[0015] As a further optimized technical solution, the repeated smearing mechanism comprises a smearing brush, the brush handle of the smearing brush is arranged on the body, and the brush head of the smearing brush extends to the end of the smearing mechanism.

[0016] As a further optimized technical solution, the smearing brush is rotatably arranged on the body, and is used for adjusting the included angle between the smearing brush and the body to adjust the smearing thickness.

[0017] As a further optimized technical solution, the brush head of the smearing brush is a sheet-shaped structure processed by a high-molecular soft material.

[0018] As a further optimized technical solution, the width of the brush head of the smearing brush is greater than the width of the smearing end of the smearing plate.

[0019] As a further optimized technical solution, the smearing plate is in the shape of an isosceles triangle, and the base of the isosceles triangle constitutes the end of the smearing plate for smearing.

[0020] Beneficial effects: First, through the detachable connection design of the connection unit and the packaging container, the direct delivery of the anesthetic from the container to the application unit is realized, completely eliminating the step of manually accessing the anesthetic. This design not only shortens the operation time of single application, but also greatly improves the overall efficiency of medical and cosmetic operations, and avoids direct contact of the hands with the anesthetic, thereby reducing the risk of cross contamination from the source, in line with medical-grade hygiene standards. In addition, the end of the anesthetic outlet channel extends to one side of the end of the application unit, which cooperates with the application mechanism, so that the anesthetic flowing out of the end of the anesthetic outlet channel can be evenly applied by the application mechanism to the operation area. Compared with manual application, it does not need to repeatedly adjust the application thickness and uniformity, effectively improving the application efficiency and solving the common problems of local accumulation, uneven thickness in traditional manual application, significantly reducing the risk of poisoning caused by excessive absorption of anesthetic and the problem of poor analgesic effect caused by insufficient dosage.

[0021] Further, the repeated application mechanism is used to reapply the anesthetic applied by the application unit, and multiple applications of the anesthetic can further ensure the uniformity of the anesthetic application. The repeated application mechanism has a brush head width greater than the application end of the application plate, which ensures that the secondary flattening can completely cover the primary application area, especially the edge part, and eliminates the common leakage or accumulation phenomenon in the edge part of traditional application.

[0022] Further, the multi-angle adjustable function of the application brush can adjust the thickness of the application. Specifically, the application brush is rotationally connected with the body, and the included angle between the application brush and the body directly determines the pressure of the brush head on the skin surface. When the brush handle is rotated towards the body, the included angle decreases, the contact angle of the brush head with the skin is more "steep", and the normal pressure component of the brush head on the skin increases. Greater pressure will promote the spread of the anesthetic, further thinning the accumulated anesthetic layer, and ultimately forming a thinner application thickness. Conversely, when the included angle increases, the contact between the brush head and the skin is more "gentle", the vertical pressure component decreases, the extrusion effect on the anesthetic decreases, and the anesthetic remains in a relatively concentrated accumulation state under the action of its own viscosity, thereby forming a thicker application layer. In addition, the repeated application mechanism cooperates with the soft polymer brush head to ensure the flattening effect and avoid mechanical stimulation to the skin, thereby improving the comfort of the patient.

[0033] Embodiment 1

[0034] As shown in Figure 1 , Figure 2 and Figure 3 , the medicine smearing device comprises a body 100, the proximal end (the end close to the operator) of the body 100 has a connecting unit 110, in the embodiment, the connecting unit 110 can be an internal thread structure, which is detachably connected with the external thread outlet of a packaging container 200 containing medicine (such as a medicine hose). Or the connecting unit 110 has an external thread interface, which is detachably connected with the internal thread outlet of the packaging container 200 containing medicine. In other embodiments, the connecting unit 110 can also be a buckle structure or a magnetic attraction structure, as long as it can realize stable detachable connection with the packaging container 200.

[0035] The distal end (the end away from the operator) of the body 100 has a smearing unit 120, which is used for uniformly smearing the medicine on the skin surface. The body 100 is also provided with a medicine outlet channel 130, which is linear in shape and can improve the medicine discharging efficiency. One end of the medicine outlet channel 130 is in communication with the connecting unit 110, and the other end extends to one side of the end of the smearing unit 120, and the end of the medicine outlet channel 130 does not exceed the end of the smearing unit 120. In this way, the medicine can be prevented from being accumulated on the skin due to direct dropping without passing through the smearing mechanism. The end of the medicine outlet channel 130 is also provided with a diameter collection port 131, the inner diameter of which is smaller than that of the main part of the medicine outlet channel 130, which can control the discharging amount of the medicine and prevent the medicine from flowing out too fast.

[0036] The end of the applying unit 120 is provided with a uniform applying mechanism. When the medicine in the package container 200 is extruded and flows out of the end of the applying unit 120 through the medicine outlet channel 130, the uniform applying mechanism is used to directly apply the medicine uniformly.

[0037] In this embodiment, the uniform applying mechanism includes a straight or rectangular applying plate 121 which is in contact with the skin. In this embodiment, the end of the applying plate 121 which is in contact with the skin is straight (in this embodiment, the applying plate 121 is in the shape of an isosceles triangle, and the base of the isosceles triangle constitutes the end which is in contact with the skin), and in other embodiments, the end of the applying plate 121 which is in contact with the skin can also be rectangular when the end of the applying plate 121 is soft. The end of the applying plate 121 is provided with a limiting groove 123, and a strip-shaped roller 122 is rotatably clamped in the limiting groove 123. The axis of the strip-shaped roller 122 is parallel to the edge of the end of the applying plate 121, and part of the structure of the strip-shaped roller 122 extends into the collecting opening 131 at the end of the medicine outlet channel 130. When the medicine flows out of the collecting opening 131, it first contacts the strip-shaped roller 122. As the device moves on the surface of the skin, the strip-shaped roller 122 rotates and uniformly brings the medicine to the surface of the skin.

[0038] The body 100 is also provided with a repeated applying mechanism which is arranged on the side of the applying unit 120 which is away from the medicine outlet channel 130, and is used to flatten the medicine which has been initially applied. The repeated applying mechanism includes an applying brush 140, and the brush handle 141 of the applying brush 140 is rotatably arranged on the body 100 through a hinge structure. Specifically, the hinge structure includes a pin shaft 143 which is in interference fit with the brush handle 141 and the body 100. In this way, by rotating the brush handle 141 with force, the included angle between the applying brush 140 and the body 100 can be adjusted, and the included angle can be maintained. In other embodiments, other fixing structures can also be arranged to maintain the state of the adjusted included angle of the applying brush 140. In this way, by rotating the brush handle 141, the included angle between the applying brush 140 and the body 100 can be adjusted, so as to control the thickness of the applied medicine.

[0039] Specifically, during the adjustment of the included angle between the applying brush 140 and the body 100, the included angle directly determines the pressure of the brush head 142 on the medicine on the surface of the skin. When the brush handle 141 of the applying brush 140 is rotated towards the body 100, the included angle decreases, the contact angle of the brush head 142 with the skin is more "steep", and the normal pressure component of the brush head on the skin increases. The larger pressure will promote the medicine to spread and spread around, and the originally accumulated medicine layer is further thinned, and finally a relatively thin applied thickness is formed. Conversely, when the included angle increases, the contact of the brush head 142 with the skin is more "gentle", the normal pressure component decreases, the extrusion effect on the medicine decreases, and the medicine remains relatively concentrated in the accumulated state under the self-adhesion effect, thereby forming a relatively thick applied layer.

[0040] In the embodiment, the brush head 142 of the application brush 140 extends to the end of the application mechanism (i.e. below the strip-shaped roller 122), and the brush head 142 is a sheet structure made of a high polymer soft material such as silica gel. The sheet structure of the brush head 142 has different effective contact areas with the skin at different angles. When the angle is small, the brush head presses the skin at an inclined angle, the actual contact area is long and narrow, the pressure density on the unit area is higher, and the anesthetic is more easily pushed to the edge to diffuse; when the angle is large, the contact area of the brush head 142 with the skin is wider, the pressure distribution is more uniform, and the resistance of the anesthetic during diffusion is smaller, and it is easier to maintain a certain thickness. The dynamic change of the contact area and the pressure gradient cooperate with each other to realize the accurate control of the application thickness, and can ensure the leveling effect and avoid stimulating the skin.

[0041] In addition, the brush head 142 made of a high polymer soft material has a certain elastic deformation ability and will form different bending radii at different angles, thereby more conveniently realizing control of the application thickness of different anesthetics. When the angle is small, the brush head 142 is bent more, and the “flowing slope” formed by the edge is steeper, which can guide the anesthetic to flow to a wider range; when the angle is large, the brush head 142 is bent gently, and the edge flow guiding effect is weakened, and the flowability of the anesthetic in the contact area is reduced, thereby maintaining a thicker accumulation state.

[0042] The width of the brush head 142 of the application brush 140 is greater than the width of the application end of the application plate 121, so that in the secondary leveling, the entire area applied by the application plate 121 can be covered, and the edge area can be better treated to prevent the edge from accumulating anesthetics or not being applied in place.

[0043] Further, the brush head 142 of the application brush 140 is also an isosceles triangle shape, and the base of the isosceles triangle constitutes the end of the brush head 142 in contact with the skin. The purpose of this design is that the base of the isosceles triangle is a straight line structure, which is compatible with the shape of the application end of the application plate 121, and can better fit the skin surface. Whether it is a flat skin area or a slightly curved part, the straight line contact end can ensure that the contact pressure between the brush head 142 and the skin is more uniform, avoid the problem of poor local leveling effect caused by insufficient contact, and ensure that the anesthetic layer is evenly stressed during secondary leveling.

[0044] The working process of the embodiment is as follows: in use, the packaging container 200 containing medicine is connected and fixed with the connecting unit 110, the operator holds the body 100, the strip-shaped roller 122 of the smearing unit 120 is lightly attached to the skin surface where the medicine needs to be smeared, the packaging container 200 is squeezed, the medicine enters the medicine outlet channel 130 through the connecting unit 110, and then flows out through the collecting orifice 131 and contacts the strip-shaped roller 122; the device is moved, the strip-shaped roller 122 rotates on the skin surface, and the medicine is uniformly smeared on the skin; at the same time, the smearing brush 140 moves with the device, and since the width of the brush head 142 is greater than the width of the smearing end of the smearing plate 121, the medicine and the edge area after being smeared by the strip-shaped roller 122 can be fully and secondarily smoothed, so that uniform smearing is ensured. If the thickness of the medicine needs to be adjusted, the brush handle 141 is rotated to change the included angle between the smearing brush 140 and the body 100, the smaller the included angle, the greater the pressure of the brush head 142 on the medicine, and the thinner the smearing thickness, and vice versa.

[0045] In summary, the medicine smearing device provided by the application directly connects with the packaging container 200 through the connecting unit 110, simplifies the medicine taking process, controls the medicine outlet amount through the medicine outlet channel 130 and the collecting orifice 131, cooperates with the rotation of the strip-shaped roller 122 to realize the initial uniform smearing of the medicine, and then performs secondary smoothing through the smearing brush 140 with the width of the brush head 142 being greater than the width of the smearing end of the smearing plate 121 and being adjustable, so that the problem of uneven smearing in the traditional manual smearing is effectively solved; at the same time, the whole operation process is simple and efficient, the smearing time is shortened, the operation risk is reduced, and the device has high practical value.

[0046] It can be understood that the above description is only exemplary, and the embodiments of the application are not limited in this regard.

[0047] The above is only a preferred embodiment of the application, and is not intended to limit the application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the application is within the protection scope of the claims of the application.
