DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0031] Example 1

[0032] like Figure 1-Figure 11As shown, this embodiment provides a multifunctional quantitative drug delivery device, including a drug dispensing head 1, wherein the drug dispensing head 1 includes a bending portion 2 and a connecting portion 3; the bending portion 2 is connected to a ball 4, and a first angle is formed between the bending portion 2 and the connecting portion 3; the connecting portion 3 is threadedly connected to a medicine squeezing bottle 5, and a pressing portion 6 is provided at one end of the medicine squeezing bottle 5 away from the connecting portion 3; a drug dispensing tube 7 is provided in the medicine squeezing bottle 5, and the drug dispensing tube 7 extends in a direction away from the pressing portion 6; when the pressing portion 6 is pressed, the ointment in the medicine squeezing bottle 5 is evenly coated on the surface of the ball 4 through the drug dispensing tube 7.

[0033] The curved portion 2 is located above the connecting portion 3, the connecting portion 3 is arranged along the height direction, and the curved portion 2 is bent toward the first direction. The curved portion 2 is aligned with the part of the user's skin to be massaged, and then the ball 4 is brought into contact with the part of the user's skin to be massaged.

[0034] The connecting part 3 is threadedly connected to the medicine squeezing bottle 5. The connecting part 3 is fixed and the medicine squeezing bottle 5 is rotated, so that the medicine dispensing head 1 and the medicine squeezing bottle 5 are fixed or separated, which makes it convenient to disassemble the medicine dispensing head 1 and replace the medicine squeezing bottle 5.

[0035] The bottom of the squeeze bottle 5 is provided with a pressing portion 6, which is a concave surface sunken into the squeeze bottle 5. The squeeze bottle 5 is filled with ointment, and the end of the medicine outlet tube 7 away from the squeeze bottle 5 is provided with a medicine outlet, which is in contact with the ball 4. The ball 4 serves to isolate the outside air and the second pipe 12, so that the second pipe 12 does not directly contact the air, thereby preventing the ointment from being exposed to the air and causing the ointment to deteriorate.

[0036] When the user presses the pressing part 6 , that is, applies a force toward the inside of the medicine squeezing bottle 5 , the ointment in the medicine squeezing bottle 5 can be pushed into the medicine outlet tube 7 , and then the ointment in the medicine outlet tube 7 is sprayed onto the surface of the ball 4 .

[0037] The pressing part 6 is arranged at the bottom of the squeeze medicine bottle 5, and the pressing part 6 is a groove. The cross section of the groove can be parabolic or semicircular, which is not limited here. In this embodiment, the cross section of the groove is parabolic as an example. When the multifunctional quantitative drug delivery device of the present invention is used to massage the user's skin, the squeeze medicine bottle 5 is placed vertically, and the pressing part 6 is pressed, that is, a vertical force is applied to the squeeze medicine bottle 5, so that the ointment passes through the first pipe 11 and the second pipe 12 and is applied to the ball 4. The first angle between the curved portion 2 and the connecting portion 3 can be an acute angle, or a right angle or an obtuse angle. In this embodiment, the first angle is an obtuse angle in the range of 120°-150° as an example. Since the curved portion 2 and the connecting portion 3 are not located on the same straight line, when the ball 4 is used to massage the user's skin, the force and the pressing force borne by the ball 4 are respectively located in two different directions, thereby reducing the force on the medicine dispensing head 1 and extending the service life of the medicine dispensing head 1.

[0038] The medicine dispensing head 1 of the present invention is an integrated structure composed of a bending portion 2 and a connecting portion 3. The integrated structure medicine dispensing head 1 is used to withstand the force generated when the ball 4 is pressed, which can improve the structural strength of the medicine dispensing head 1 and make the medicine dispensing of the medicine dispensing head 1 more stable. The medicine dispensing head 1 is detachably connected to the medicine squeezing bottle 5, which is convenient for the user to remove the medicine squeezing bottle 5 from the medicine dispensing head 1, replace the medicine squeezing bottle 5, or add ointment to the medicine squeezing bottle 5 when the amount of ointment in the medicine squeezing bottle 5 is insufficient.

[0039] The curved portion 2 has an end away from the connecting portion 3 and is provided with a receiving opening 8. The ball 4 is disposed in the receiving opening 8 and is rollingly connected to the receiving opening 8. The ball 4 isolates the medicine outlet tube 7 from the outside air to reduce air contamination of the ointment.

[0040] The receiving opening 8 has a certain curvature to fit the ball 4. The ball 4 contacts the user's skin. When the ball 4 is used to massage the user's skin, the ointment on the ball 4 can be evenly applied to the user's skin. Under the action of the friction between the ball 4 and the skin, the ball 4 rotates in the receiving opening 8. The ointment is slowly released in a massage manner, and the ointment gradually penetrates into the skin, achieving the purpose of relaxing the meridians and activating the collaterals and dredging the blood vessels.

[0041] The receiving port 8 has an arc surface 9, the first part of the ball 4 abuts against the arc surface 9, the second part of the ball 4 extends outward relative to the receiving port 8, and the ball 4 is in clearance with the receiving port 8; the ball 4 is used to perform rolling massage on the user's skin and quantitative drug administration. The rolling massage method can accelerate blood circulation and promote metabolism. The ball 4 is a spherical structure, the diameter of the ball 4 is smaller than the radial size of the receiving port 8, and there is a gap between the ball 4 and the receiving port 8, so that when the ball 4 rotates in the receiving port 8, a part of the ointment covering the surface of the second part of the ball 4 is applied to the user's skin surface, and the other part of the ointment flows back to the first part of the ball 4 from the gap between the receiving port 8 and the ball 4. The ball 4 is continuously rotated so that the first part of the ball 4 extends outward relative to the receiving port 8, and the second part of the ball 4 rotates back into the receiving port 8, and the first part of the ball 4 is used to massage the user's skin, thereby achieving the effect of saving ointment and reusing the ointment.

[0042] The first part of the ball 4 is located in the receiving port 8, and the second part of the ball 4 protrudes outward relative to the receiving port 8. During the rotation of the ball 4, the first part of the ball 4 rotates from the inside of the receiving port 8 to the outside of the receiving port 8, and the second part of the ball 4 rotates from the outside of the receiving port 8 to the inside of the receiving port 8.

[0043] The multifunctional quantitative drug delivery device provided in this embodiment includes a drug dispensing head 1, which includes a curved portion 2 and a connecting portion 3; the curved portion 2 is connected to a ball 4, and a first angle is formed between the curved portion 2 and the connecting portion 3; the connecting portion 3 is threadedly connected to a squeeze bottle 5, and a pressing portion 6 is provided at one end of the squeeze bottle 5 away from the connecting portion 3; a drug dispensing tube 7 is provided in the squeeze bottle 5, and the drug dispensing tube 7 extends in a direction away from the pressing portion 6; when the pressing portion 6 is pressed, the ointment in the squeeze bottle 5 is evenly coated on the surface of the ball 4 through the drug dispensing tube 7. When in use, the user presses the pressing portion 6 to squeeze the ointment in the squeeze bottle 5 into the drug dispensing tube 7, and the ointment in the drug dispensing tube 7 is coated on the ball 4 under the action of positive pressure. The ball 4 is brought into contact with the user's skin to push the drug dispensing head 1, and under the action of the friction between the ball 4 and the user's skin, the ball 4 rotates in the receiving port 8, and the ointment on the ball 4 is evenly coated on the surface of the user's skin. The ointment is slowly released by massaging, and the ointment gradually penetrates into the skin, achieving the purpose of relaxing the meridians and activating the collaterals, and dredging the blood vessels. When the ball 4 rolls on the user's skin surface, the user continues to press the pressing part 6, and the surface of the ball 4 abutting against the medicine outlet tube 7 changes, and the ointment is evenly coated on the surface of the ball 4, so that the ointment is evenly coated on the user's skin surface. The ball 4 is in contact with the user's skin, and the user's skin can be massaged. In the case where the ointment is evenly coated on the surface of the ball 4, the ball 4 rotates one circle, and the dosage is fixed. The user only needs to control the number of rotations of the ball 4 to control the dosage. The contact area between the ball 4 and the skin is small. After massaging one part of the user's skin surface, another part of the user's skin surface can be massaged, thereby achieving precise drug delivery in different small areas. Compared with the device of squeezing the medicine head 1 to spray the ointment in the prior art, the present invention adopts the method of pressing the pressing part 6 of the medicine bottle 5 to reduce the force on the medicine head 1, thereby extending the service life of the medicine head 1. The roller ball 4 can be used to roll and apply the ointment, which is convenient to use and has a massage function, thereby promoting the skin to absorb the ointment, accelerating blood circulation and stimulating metabolism.

[0044] Example 2

[0045] like Figure 1-Figure 11 As shown, this embodiment provides a multifunctional quantitative drug delivery device, including a drug dispensing head 1, wherein the drug dispensing head 1 includes a bending portion 2 and a connecting portion 3; the bending portion 2 is connected to a ball 4, and a first angle is formed between the bending portion 2 and the connecting portion 3; the connecting portion 3 is threadedly connected to a medicine squeezing bottle 5, and a pressing portion 6 is provided at one end of the medicine squeezing bottle 5 away from the connecting portion 3; a drug dispensing tube 7 is provided in the medicine squeezing bottle 5, and the drug dispensing tube 7 extends in a direction away from the pressing portion 6; when the pressing portion 6 is pressed, the ointment in the medicine squeezing bottle 5 is evenly coated on the surface of the ball 4 through the drug dispensing tube 7.

[0046] The multifunctional quantitative dosing device also includes a connecting head 10, the two ends of which are respectively connected to the medicine dispensing head 1 and the medicine squeezing bottle 5, and the end surface of the connecting head 10 close to the medicine squeezing bottle 5 is elliptical; the connecting head 10 is used to fix the position of the medicine dispensing head 1 when the medicine squeezing bottle 5 is rotated.

[0047] The medicine outlet pipe 7 includes a first pipe 11 and a second pipe 12, wherein the first pipe 11 is vertically arranged, and the second pipe 12 is bent, and the bending direction of the second pipe 12 is consistent with that of the bent portion 2, and the first pipe 11 and the second pipe 12 are connected or integrally formed.

[0048] A protective shell 17 is disposed on the outer side of the connector 10 . The protective shell 17 is a cylindrical structure. The connector 10 and the protective shell 17 are clearance-matched.

[0049] The connector 10 is arranged between the medicine dispensing head 1 and the medicine squeezing bottle 5. The connector 10 is a columnar structure, and the end face of the connector 10 facing the medicine squeezing bottle 5 is elliptical. The end face of the connector 10 facing the medicine dispensing head 1 is a gradual structure, and the radial dimension of the end face gradually decreases in the direction close to the medicine dispensing head 1. The opening at the top of the medicine squeezing bottle 5 is circular, and the end face of the connector 10 facing the medicine squeezing bottle 5 is set to be elliptical, and the two ends of the long axis of the elliptical end face of the connector 10 abut against the inner wall of the protective shell 17, and the two ends of the short axis of the elliptical end face of the connector 10 have a gap with the inner wall of the protective shell 17. When the user tightens or loosens the connection between the medicine squeezing bottle 5 and the connecting head 10, the medicine squeezing bottle 5 rotates, and the connecting head 10 tends to rotate relative to the protective shell 17. At this time, the elliptical end face of the connecting head 10 is stuck on the inner wall of the protective shell 17, thereby preventing the connecting head 10 and the medicine dispensing head 1 from rotating when tightening or loosening the medicine squeezing bottle 5, thereby improving the stability of medicine dispensing.

[0050] The maximum width of the gap between the elliptical end face of the connector 10 and the protective shell 17 is 0.5 mm. This gap allows the connector 10 to move in the height direction when it is squeezed in the height direction, thereby driving the first pipe 11 and the second pipe 12 to move away from the squeezing bottle 5.

[0051] The medicine outlet pipe 7 includes a first pipe 11 and a second pipe 12, wherein the first pipe 11 is vertically arranged, and the second pipe 12 is bent, and the bending direction of the second pipe 12 is consistent with that of the bent portion 2, and the first pipe 11 and the second pipe 12 are connected or integrally formed.

[0052] The first pipe 11 passes through the connector 10 . An elastic component 13 is sleeved on one end of the first pipe 11 close to the second pipe 12 . In this embodiment, the elastic component 13 is a spring.

[0053] The first pipe 11 is inserted into the squeeze bottle 5, and the first pipe 11 is connected to the second pipe 12. After the ointment in the squeeze bottle 5 is subjected to the squeezing force, the ointment is squeezed into the first pipe 11 under the action of positive pressure, and then enters the second pipe 12 from the first pipe 11.

[0054] The first pipe 11 is located in the connecting portion 3, and the second pipe 12 is located in the curved portion 2. The second pipe 12 has the same curved direction as the curved portion 2. After the ointment enters the first pipe 11, it is sprayed onto the ball 4 through the second pipe 12. The ball 4 contacts the user's skin, and the user pushes the ball 4 to rotate, so that the ointment is evenly applied to the user's skin surface.

[0055] The first pipe 11 passes through the connector 10, the first end of the first pipe 11 is inserted into the squeeze bottle 5, and the second end of the first pipe 11 is connected to or integrally formed with the second pipe 12. When the user squeezes the squeezing portion at the bottom of the squeeze bottle 5, the first pipe 11 extends away from the squeeze bottle 5, and the elastic component 13 stretches. When the external force on the squeezing portion disappears, the elastic component 13 gradually recovers from the stretched state to its original length, so as to drive the first pipe 11 back to the initial position.

[0056] like Figure 5 As shown, preferably, the first cavity 19 and the second cavity 20 are respectively provided on both sides of the second pipe 12, and the connecting line of the first cavity 19 and the second cavity 20 is a first straight line, and the first straight line and the central axis of the second pipe 12 are perpendicular to each other. The second pipe 12 passes through the space between the first cavity 19 and the second cavity 20, and the first cavity 19 and the second cavity 20 have a limiting effect on the second pipe 12 to ensure that the bending direction of the second pipe 12 is the same as the bending direction of the curved portion 2. The first straight line is perpendicular to the central axis of the second pipe 12, which can reduce the resistance of the second pipe 12, so that the second pipe 12 smoothly transitions from the end connected to the first pipe 11 to the end connected to the receiving port 8, thereby improving the drug dispensing effect.

[0057] A first buckle is provided at one end of the first pipe 11 located in the squeeze bottle 5, and the first buckle prevents the ointment from being sprayed out from the first pipe 11 through the second pipe 12 when the external atmospheric pressure is lower than the pressure in the squeeze bottle 5. A second buckle is provided at one end of the second pipe 12 close to the accommodating opening 8, and the second buckle prevents the ointment from being sprayed out from the second pipe 12 when the external atmospheric pressure is lower than the pressure in the squeeze bottle 5.

[0058] The medicine discharging pipe 7 of this embodiment includes a first pipe 11 and a second pipe 12. The first pipe 11 is arranged vertically, and the second pipe 12 is arranged in a curved direction. The second pipe 12 is consistent with the bending direction of the curved portion 2. The first pipe 11 and the second pipe 12 are connected or integrally formed. The first pipe 11 runs through the connector 10, and an elastic component 13 is sleeved on one end of the first pipe 11 close to the second pipe 12. One side of the connector 10 is threadedly connected to the medicine squeezing bottle 5, and the other side of the connector 10 is threadedly connected to the medicine discharging head 1. The connector 10 can be removed from the top of the medicine squeezing bottle 5, or from the bottom of the medicine discharging head 1. When the user presses the pressing part 6 at the bottom of the medicine squeezing bottle 5, the ointment in the medicine squeezing bottle 5 is pressed into the first pipe 11. At this time, the first pipe 11 extends in a direction away from the medicine squeezing bottle 5, and the elastic component 13 sleeved on the first pipe 11 is stretched, and the ointment is sprayed on the ball 4 from the first pipe 11 through the second pipe 12. When the user removes the force applied to the squeezing portion, the elastic component 13 gradually recovers to its original length from the stretched state, driving the first pipe 11 back to the initial position.
