[0055] The following describes in detail the ointment quantitative applicator according to the embodiments of the present utility model with reference to the accompanying drawings.

[0056] Referring to Figures 1 to 6 As shown, the ointment quantitative applicator according to the embodiments of the present utility model includes a peristaltic pump 10, a medicine storage cylinder 20 and an application head 30.

[0057] Specifically, the peristaltic pump 10 includes a motor 101 and a pump head 102 driven by the motor 101. The pump head 102 has a medicine inlet 1021 and a medicine outlet 1022. The peristaltic pump 10 is the core component of this device, and the motor 101 provides the power source. The pump head 102 generally includes a pump head 102 housing, a rolling extrusion wheel assembly provided inside the pump head 102 housing, and a hose. The motor 101 drives the rolling extrusion wheel assembly to rotate. The medicine inlet 1021 on the pump head 102 is provided at one end of the hose, and the medicine inlet 1021 is connected to the medicine storage cylinder 20, thus enabling the connection between the medicine storage cylinder 20 and one end of the hose. The medicine outlet 1022 is provided at the other end of the hose. When the rolling extrusion wheel rotates, the ointment in the medicine storage cylinder 20 is conveyed from the medicine inlet 1021 to the medicine outlet 1022 by compressing and releasing the catheter, thereby achieving the precise conveyance of the ointment.

[0058] The advantage of the peristaltic pump 10 is that the ointment will not be contacted during the conveyance process, avoiding contamination. At the same time, the flow rate can also be precisely controlled by adjusting the rotation speed of the motor 101. This is crucial for the treatment of skin injuries that require precise dosage measurement.

[0059] The medicine storage cylinder 20 is detachably provided on the pump head 102 and is connected to the medicine inlet 1021. The medicine storage cylinder 20 is used to store the ointment. The detachable design of the medicine storage cylinder 20 enables the medicine storage cylinder 20 to be quickly disassembled and replaced, thereby facilitating the replacement and addition of the medicine. In addition, it is also convenient for cleaning and disinfection to ensure medical hygiene.

[0060] The applicator head 30 is provided on the pump head 102, and the applicator head 30 has an application surface adapted to contact the human body surface. A through hole H301 for connecting the medicine outlet 1022 with the application surface is provided on the applicator head 30. The material of the application surface needs to have a certain softness to avoid irritating or damaging the skin. At the same time, the shape of this surface also needs to be reasonably designed so that it can fit the skin surface to ensure uniform application of the ointment.

[0061] The through hole H301 in the applicator head 30 connects the medicine outlet 1022 of the pump head 102 with the application surface, enabling the ointment conveyed by the peristaltic pump 10 to be dispersed onto the application surface through the through hole H301 and then applied to the skin wound. Parameters such as the size and quantity of the through hole H301 need to be reasonably set to optimize the distribution effect of the ointment on the application surface.

[0062] When using this ointment quantitative applicator, first connect the medicine storage cylinder 20 filled with ointment to the pump head 102, and then start the motor 101. The peristaltic pump 10 can convey the ointment in the medicine storage cylinder 20 to the medicine outlet 1022 according to the set flow rate. Medical staff or patients only need to press the application surface of the applicator head 30 tightly against the skin for application, and the ointment can be evenly applied to the wound surface. The application amount can be adjusted according to needs by controlling the time or rotation speed of the peristaltic pump 10.

[0063] According to the ointment metering applicator provided by the embodiments of the present utility model, by integrating a peristaltic pump 10, a detachable medicine storage cylinder 20, and an applicator head 30 with an application surface, automatic extrusion of the ointment can be achieved, avoiding the inconvenience caused by manual operation. And through the control of the peristaltic pump 10, the dose of the ointment can be effectively controlled, thereby improving the accuracy of applying medicine to patients with skin injuries and ensuring that the expected therapeutic effect can be achieved. In addition, the device has a simple structure, can be operated by hand, and is simple to operate and convenient to use.

[0064] Referring to Figures 1 to 3 As shown, in an embodiment of the present utility model, the pump head 102 has a first side surface and a second side surface. An interface ring platform 1023 is provided on the first side surface, and the second side surface intersects the first side surface perpendicularly.

[0065] The medicine inlet 1021 is provided in the interface ring platform 1023. One end of the medicine storage cylinder 20 is adapted to be docked with the interface ring platform 1023 and communicated with the medicine inlet 1021. The medicine outlet 1022 is provided on the second side surface.

[0066] In this embodiment, the function of the interface ring platform 1023 is to be docked with one end of the medicine storage cylinder 20, so that the medicine storage cylinder 20 can be firmly and detachably connected to the pump head 102. The medicine inlet 1021 inside the interface ring platform 1023 is communicated with the medicine storage cylinder 20 after the medicine storage cylinder 20 is docked, so that the peristaltic pump 10 can extract the ointment from the medicine storage cylinder 20. The design of the interface ring platform 1023 makes the installation and disassembly of the medicine storage cylinder 20 very simple. Just insert one end of the medicine storage cylinder 20 into the interface ring platform 1023 for docking.

[0067] And a medicine outlet 1022 is opened on the second side surface. The position of the medicine outlet 1022 is far from the medicine inlet 1021, which is beneficial to the compact and reasonable layout of the structure. After the ointment is transported by the peristaltic pump 10, it flows out from the medicine outlet 1022, and then flows to the application surface through the through hole H301 of the applicator head 30. In addition, setting the medicine outlet 1022 on the second side surface can also avoid interference with other parts when the pump head 102 performs the application operation, making it more convenient to use.

[0068] Referring to Figure 3 As shown, in an embodiment of the present utility model, the medicine inlet is a conical nozzle, and an outlet hole H20 is provided at one end of the medicine storage cylinder 20.

[0069] When one end of the medicine storage cylinder 20 is docked with the interface ring platform 1023, the conical nozzle is inserted into the outlet hole H20 to form a seal, so that the ointment in the medicine storage cylinder 20 is sucked into the conical nozzle under the action of the peristaltic pump 10.

[0070] In order to achieve a reliable and efficient connection between the medicine storage cylinder 20 and the pump head 102 and ensure no leakage during the medicine paste delivery process, an innovative tapered nozzle design is adopted. Specifically, the medicine inlet on the first side of the pump head 102 is designed as a tapered nozzle, and the structure of this tapered nozzle can well cooperate with the medicine outlet hole H20 of the medicine storage cylinder 20.

[0071] The inner diameter of the medicine outlet hole H20 at one end of the medicine storage cylinder 20 is between the minimum outer diameter and the maximum outer diameter of the tapered nozzle, so that the tapered nozzle can be accurately inserted into the medicine outlet hole H20 to a certain depth. The outer conical surface of the tapered nozzle precisely fits and closely adheres to the inner wall of the medicine outlet hole H20 to form a seal, thereby preventing the medicine paste from leaking during the delivery process.

[0072] The tapered nozzle design in this embodiment enables a firm and reliable sealed connection between the medicine storage cylinder 20 and the pump head 102, ensuring that all the medicine paste in the medicine storage cylinder 20 can be accurately sucked into the pump head 102 without any liquid medicine residue or overflow, avoiding waste and pollution. At the same time, the tapered structure can also play a positioning role, enabling the medicine storage cylinder 20 and the pump head 102 to automatically obtain an ideal position when docked, improving the assembly convenience. When the peristaltic pump 10 starts to work, the medicine paste in the medicine storage cylinder 20 will be orderly sucked into the tapered nozzle under its negative pressure and then transported to the medicine outlet 1022. This negative pressure transportation method avoids dead angles and blockages and ensures the smoothness of the transportation path.

[0073] Refer to Figure 3 and Figure 4 As shown, in an embodiment of the present utility model, an external thread portion is provided on the outer peripheral surface of the said one end of the medicine storage cylinder 20, and an internal thread portion adapted to the external thread portion is provided on the inner peripheral wall of the interface ring platform 1023.

[0074] Through the threaded connection design, a reliable, accurate, and easily detachable and installable connection between the medicine storage cylinder 20 and the pump head 102 is achieved, and the relative position between the medicine storage cylinder 20 and the pump head 102 will be more accurate and firm. When the medicine storage cylinder 20 is screwed in and fully tightened, the centers of the medicine outlet hole H20 of the medicine storage cylinder 20 and the tapered nozzle of the pump head 102 will be highly coincident, which is beneficial to the accurate insertion of the subsequent tapered nozzle. At the same time, due to the existence of the tightening force, the medicine storage cylinder 20 will not easily shift or fall off, ensuring the reliability of the device during long-term use. In addition, the threaded connection method also enables the medicine storage cylinder 20 to be quickly disassembled and replaced. Just rotate it a few turns in the reverse direction, and the medicine storage cylinder 20 can be completely removed from the pump head 102, greatly facilitating maintenance work such as cleaning and disinfection.

[0075] Refer to Figure 5As shown, in an embodiment of the present utility model, the applicator head 30 is detachably connected to the pump head 102. The medicine outlet is a cylindrical nozzle. When the applicator head 30 is connected to the pump head 102, the cylindrical nozzle is adapted to be inserted into the through hole H301, and the outlet end of the cylindrical nozzle is adjacent to the application surface.

[0076] In this embodiment, the applicator head 30 and the pump head 102 are designed to be detachably connected, which enables the two to be conveniently assembled and disassembled, facilitating cleaning, maintenance and replacement. The connection method can adopt common mechanical connection methods such as snap fasteners and threads. In addition, this detachable connection method also allows the applicator head 30 to be used independently after being disassembled. For example, after the ointment is extruded onto the applicator head 30 by the peristaltic pump 10, the applicator head 30 can be detached from the pump head 102, and then the applicator head 30 can be used for applying medicine. In this way, a more convenient and flexible usage method is provided.

[0077] In addition, the medicine outlet 1022 of the pump head 102 is designed as a cylindrical nozzle. The outer diameter of the cylindrical nozzle is slightly smaller than the inner diameter of the through hole H301 on the applicator head 30, so that when the applicator head 30 is connected to the pump head 102, the cylindrical nozzle can be accurately inserted into the through hole H301. After the ointment is transported by the peristaltic pump 10 and flows out from the outlet end of the cylindrical nozzle, it can directly reach the application surface. The flow path of the ointment is smoother and straighter, ensuring that the ointment is quickly distributed to the application surface and also ensuring the quality and effect of medicine application.

[0078] Advantageously, the application surface is provided with a concave arc-shaped groove H302, and the through hole H301 is located in the middle of the concave arc-shaped groove H302 to extrude the ointment into the concave arc-shaped groove H302. The concave arc-shaped groove H302 is a shallow groove and should not be too deep. For example, its depth is 2 to 5 mm. On the one hand, the through hole H301 is designed at the center position of the concave arc-shaped groove H302, which can make the ointment flow out and concentrate in the groove first, and then spread evenly around, so as to obtain a better distribution effect. On the other hand, the concave arc-shaped groove H302 can store the ointment and keep the ointment from easily overflowing on the applicator head 30.

[0079] Refer to Figure 5 As shown, in an embodiment of the present utility model, the second side is provided with a plug-in groove H10. The cylindrical nozzle is located in the plug-in groove H10, and an annular magnetic sheet 1024 is arranged in the plug-in groove H10, and the annular magnetic sheet 1024 surrounds the cylindrical nozzle.

[0080] The applicator head 30 has a connection end, the connection end is adapted to the plug-in groove H10, and a metal sheet 302 adapted to be attracted to the annular magnetic sheet 1024 is arranged at the connection end.

[0081] During installation, simply align the connecting end of the applicator head 30 with the insertion slot H10 of the pump head 102, and then slowly approach and insert it. When the metal sheet 302 gradually approaches the annular magnetic sheet 1024, due to the magnetic force, the metal sheet 302 will be automatically adsorbed on the annular magnetic sheet 1024, thus reliably connecting the applicator head 30 and the pump head 102 together.

[0082] This magnetic adsorption connection method is extremely simple to operate. There is no need for manual buckling or tightening, and only a one-time gentle push is required to complete the assembly. More importantly, due to the existence of the magnetic force, there will be no shaking or displacement between the applicator head 30 and the pump head 102, ensuring the stability of the ointment delivery path. When disassembly is required, only a certain external force needs to be applied to overcome the magnetic force, and then the entire applicator head 30 can be pulled out from the pump head 102. This is much simpler and faster than the method of manual screwing or buckling, which is beneficial for the frequent disassembly, cleaning, disinfection, and maintenance of the applicator head 30.

[0083] Refer to Figures 2 to 3 and Figure 6 As shown, in an embodiment of the present invention, the applicator head 30 further has an application end, and a flexible layer 301 is provided on the end face of the application end, and the application surface is located on the flexible layer 301. The end face of the applicator head 30 is the part that directly contacts the human skin. Although traditional hard materials are wear-resistant and durable, they will cause irritation or discomfort to the skin when contacting. By providing the flexible layer 301 on the end face, the affinity with the skin can be increased, the contact pressure can be reduced, and thus the comfort during the application process can be improved. Common choices include materials such as non-woven fabric, foam plastic, and artificial leather.

[0084] The flexible layer 301 can be connected to the main body of the applicator head 30 by a variety of different assembly methods. For example, by bonding, buckling, etc., to ensure that the flexible layer 301 can be firmly installed and at the same time has a certain degree of detachability for easy replacement and maintenance.

[0085] Refer to Figures 1 to 3 As shown, in an embodiment of the present invention, it further includes a hand-held handle 11, the hand-held handle 11 is connected to the pump head 102 and is suitable for being held by the user, and the motor 101 is arranged in the hand-held handle 11. Preferably, some auxiliary operation areas can be reserved on the hand-held handle 11, such as a switch button, an adjustment key, a power indicator light, etc., to facilitate operations such as starting and controlling.

[0086] During actual use, the operator only needs to hold the handle part naturally with one hand or both hands, and the fingers can easily touch all the operation buttons. After turning on the power, the motor 101 starts to work and drives the pump head 102 to work. At this time, the hand-held handle 11 just acts as a force arm, and through the natural activities of the human arm and wrist parts, the applicator head 30 can be easily aligned and attached to the required medicated area for uniform and efficient application operations.

[0087] Through the design of the handheld handle 11, the ergonomics and actual operation requirements are fully integrated, greatly improving the portability and operability of the entire device.

[0088] Preferably, the handheld handle 11 and the medicine storage cylinder 20 are located on the same side of the pump head 102. In this way, the overall structural layout is reasonable, and it is convenient to hold and operate.

[0089] In an embodiment of the present utility model, a cylinder cover 201 is provided at the other end of the medicine storage cylinder 20. When adding medicine, the cylinder cover 201 can be opened, which is convenient for adding medicine. In addition, it is also more convenient during cleaning and disinfection.
