Description

Technical Field

[0001] This invention relates to the field of burn unit dressing change equipment technology, specifically to an intelligent burn unit dressing change device. Background Technology

[0002] Burns generally refer to tissue damage caused by heat, including hot liquids (water, soup, oil, etc.), steam, high-temperature gases, flames, incandescent liquid or solid metals (such as molten steel, steel ingots), and strong radioactive radiation. They primarily affect the skin and / or mucous membranes, but in severe cases, can also damage subcutaneous and / or submucosal tissues, such as muscles, bones, joints, and even internal organs. Scalds are tissue damage caused by heat (such as flames, hot liquids, hot steam, hot metals, etc.), chemical substances (such as strong acids, strong alkalis, etc.), electric current, and radiation, typically specifically referring to damage to the skin and / or mucous membranes. The nine-point method, proposed by the Third Military Medical University of the Chinese People's Liberation Army, divides the adult human body surface area into 11 equal parts. The head, face, and neck account for 9%, the upper limbs for two 9% sections, the anterior and posterior trunk (each accounting for 13%) and perineum (accounting for 1%) for three 9% sections, and the lower limbs, including the buttocks, for five 9% sections plus 1% (46%).

[0003] Burns are a type of thermal damage to the skin. When an injury occurs, it is necessary to quickly remove the heat source and protect the wound for subsequent treatment. Since the skin is the body's outer defense, it is prone to infection after injury. It is necessary to protect the wound and regularly change dressings and clean it to maintain the stability of the injury. During dressing changes and cleaning, manual cleaning is usually used. However, during the burn recovery period, if skin ulceration is treated in time, a dressing change device can be used to assist and reduce the burden on the operator. However, existing dressing change devices are mostly manual, and manual application of medicine is difficult to control the force and operation of the hand, relying heavily on experience. Furthermore, other operations cannot be performed while applying medicine, resulting in low efficiency. Moreover, they can only deal with burns in one area and cannot be adjusted, so they cannot be used to assist in dressing changes on other areas such as the arms and torso, thus reducing the efficiency and comfort of use. Based on this, an intelligent dressing change device for burn departments is proposed. Summary of the Invention

The pressure pump is fixedly installed inside the rectangular frame. The output end of the pressure pump is connected to a water outlet pipe. The other end of the water outlet pipe is connected to a coil. A plurality of atomizing nozzles are connected to the bottom of the coil. The coil is fixedly installed at the bottom of the rectangular frame. The atomizing nozzles are evenly distributed in a circular linear pattern at the bottom of the coil. Both the protective shell and the telescopic inner shell have through grooves on their tops. The dimensions of the mounting cylinder are adapted to the dimensions of the through grooves.

[0014] Preferably, the telescopic roller dipping mechanism includes four high-precision electrically controlled telescopic rods, which are arranged in pairs. A telescopic sleeve is fixedly installed at the bottom end of each pair of high-precision electrically controlled telescopic rods. A flexible spring is movably sleeved inside the telescopic sleeve. The two ends of the flexible spring are respectively fixedly installed at the fixed part and the telescopic part of the telescopic sleeve. A mounting bracket is fixedly installed at the telescopic end of the telescopic sleeve. A hollow support roller is movably sleeved on the inner side of the mounting bracket via a bearing.

A fan blade is fixedly mounted on the output end of the small motor, located inside the hollow support roller, and its dimensions are compatible with those of the hollow support roller.

[0015] Preferably, the dipping cloth includes a gauze layer and an absorbent cotton layer. The gauze layer is fixedly installed on top of the absorbent cotton layer, and the dipping cloth is movably sleeved on the outside of the flexible silicone roller sleeve.

[0016] Preferably, a threaded strip is provided on the outer side of the mouth of the medicine bottle, a silicone gasket is fixedly installed on the outer side of the mouth of the medicine bottle, a fan-shaped groove is opened on the inner side of the silicone gasket, a threaded plate is fixedly installed on the inner wall of the medicine bottle, and the specifications and dimensions of the medicine bottle and the threaded strip are adapted to the specifications and dimensions of the mounting cylinder.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When using the device, the operator moves the device to the bed where the patient is lying, and then extends the length of the telescopic leg mechanism and the length of the protective shell and telescopic inner shell so that the device can span the patient's body. Then, a sterilized absorbent towel is placed at the relative position of the telescopic leg mechanism and the patient's body to prevent excess saline and medicine from flowing onto the bed. Then, the medicine bottle is filled with medicine or saline and installed on the inner side of the spraying mechanism. The hub drive motor starts to rotate and rolls through the rubber hub on the top of the outer sleeve and the central column, driving the rectangular frame to move, which in turn drives the spraying mechanism and the telescopic roller dipping mechanism to move, making it convenient to spray medicine on the patient's affected area. The dipping cloth installed at the bottom of the telescopic roller dipping mechanism absorbs water to prevent excessive liquid accumulation and makes cleaning convenient. The whole device is convenient for changing dressings on the body or limbs, increases the efficiency of dressing changes and reduces the workload of medical staff.

[0018] 2. After the medicine is applied, the small motor is started. The rotation of the small motor drives the fan blades to rotate, which causes the airflow to flow inside the hollow support roller and be discharged through the vent holes. This creates a breathable effect on the cloth, blows air onto the skin after wiping to speed up the drying of the liquid, and promotes uniform airflow. The airflow is blown simultaneously during the wiping process, which can increase breathability, facilitate the changing of medicine, and improve the overall use effect.

[0019] 3. This solution facilitates the spraying of saline or other medications using medicine bottles and a dipping cloth. It allows for the configuration of multiple medicine bottles as needed, enabling the preparation of multiple bottles for installation and operation, thus facilitating medication changes. The dipping cloth is easy to replace, clean, and disinfect. Furthermore, the overall structure is stable and easy to disassemble and assemble, making it convenient for use after disinfection and mitigating the risk of infection. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-12 This invention provides a technical solution: an intelligent dressing change device for burn units, comprising a protective shell 1, an active mechanism 4, a telescopic support mechanism 6, a medicine bottle 8, a dipping cloth 9, and a wedge strip 10. A telescopic inner shell 101 is movably sleeved on the inner side of one end of the protective shell 1. Several adjustment holes 102 are provided on both sides of the telescopic inner shell 101. Several adjustment bolts 103 are threadedly connected to the inner sides of both ends of the protective shell 1. Telescopic leg mechanisms 2 are fixedly installed at the bottom of the opposite ends of the protective shell 1 and the telescopic inner shell 101. A control panel 3 is installed on one side of the protective shell 1. A spraying mechanism 5 is installed on the outer side of the active mechanism 4. A telescopic roller dipping mechanism 7 is installed at the bottom of the active mechanism 4.

[0035] The active mechanism 4 includes a rectangular frame 401, a hub drive motor 402 is installed on the inner side of the rectangular frame 401, a rubber hub sleeve 403 is fixedly sleeved on the outer side of the hub drive motor 402, two limiting support rollers 404 are movably installed on the inner side of the rectangular frame 401 through bearing seats, and a vision acquisition camera 407 is installed at the bottom of the rectangular frame 401.

[0036] The telescopic support mechanism 6 includes three outer sleeves 601. Each of the three outer sleeves 601 has a bolt hole 602 at one end. Each of the three outer sleeves 601 has a central groove 604 inside. A central column 603 is movably sleeved inside the central groove 604. Several rubber strips 605 are fixedly installed on the top of the central column 603 and the outer sleeve 601. An internal mounting groove 606 is opened through the central column 603. A reinforcing telescopic column 608 is fixedly installed inside the central groove 604. A limit groove 607 is opened at the bottom of the central column 603.

[0037] The working principle of the above technical solution is as follows: During use, the operator moves the equipment to the bed where the patient is lying, then extends the length of the telescopic leg mechanism 2, and also extends the length of the protective shell 1 and the telescopic inner shell 101, so that the equipment can span the patient's body. If a limb is used, the arm or leg is passed through the middle of the telescopic leg mechanism 2. Then, a sterilized absorbent towel is placed at the relative position of the telescopic leg mechanism 2 and the patient's body to prevent excess saline and medication from flowing onto the bed. Then, the medicine bottle 8 is filled with medication or saline and installed inside the spraying mechanism 5. The hub drive motor 402 is started. The rotation is achieved by the rubber hub sleeve 403 rolling on top of the outer sleeve 601 and the central column 603. The rubber hub sleeve 403 and the rubber strip 605 increase friction to maintain relative stability, which then drives the rectangular frame 401 to move. This, in turn, drives the spraying mechanism 5 and the telescopic roller dipping mechanism 7 to move, facilitating the mobile spraying of medicine on the patient's affected area. The dipping cloth 9, which is attached to the bottom of the telescopic roller dipping mechanism 7, absorbs water to prevent excessive liquid accumulation and facilitates cleaning. Overall, this system is convenient for changing dressings on the body or limbs, increases the efficiency of dressing changes, and reduces the workload of medical staff.

[0038] In another implementation scheme, such as Figures 1-9 As shown, the adjustment holes 102 are linearly and evenly distributed on both sides of the telescopic inner shell 101 in a rectangular pattern, and the adjustment bolts 103 are linearly and evenly distributed inside the protective shell 1. The specifications and dimensions of the adjustment bolts 103 are compatible with the specifications and dimensions of the adjustment holes 102.

[0039] The adjustment hole 102 provides an installation position for the adjustment bolt 103 and limits the position of the protective shell 1 and the telescopic inner shell 101, so as to fix them after the length of the protective shell 1 and the telescopic inner shell 101 is adjusted, thereby increasing the structural stress. It works with the internal telescopic support mechanism 6 to increase the structural strength and facilitates the adjustment of the position as needed.

[0040] In another implementation scheme, such as Figures 1-9 As shown, a handle 104 is fixedly installed on the top of both the protective shell 1 and the telescopic inner shell 101. The handles 104 are of different sizes and are arranged in a nested manner. Side handles 106 are fixedly installed on opposite ends of both the protective shell 1 and the telescopic inner shell 101.

[0041] The size of the handle 104 is designed to avoid mutual obstruction when the protective shell 1 and the telescopic inner shell 101 are adjusted. The two sizes of the handle 104 are fitted together with the inner and outer walls, making it easy to lift when they overlap. This facilitates the handling of the equipment and allows for transport via the side handle 106. It also facilitates the application of force at both ends and the adjustment of the extension length, making operation easier and increasing the relative stability of the structure.

[0042] In another implementation scheme, such as Figures 1-9 As shown, the telescopic leg mechanism 2 includes two telescopic outer legs 201. An upper limit arc plate 204 is fixedly installed on the opposite side of the top of the two telescopic outer legs 201. A telescopic inner leg 202 is movably sleeved inside each of the two telescopic outer legs 201. A bottom support leg 203 is fixedly installed at the bottom of the telescopic inner leg 202. A lower flexible arc plate 205 is fixedly installed at the top of the bottom support leg 203. The position of the lower flexible arc plate 205 corresponds to the position of the upper limit arc plate 204.

[0043] During adjustment, the telescopic inner leg 202 extends outward from the inner side of the telescopic outer leg 201 and is fixed by bolts, facilitating the adjustment of the height of the protective shell 1 and the telescopic inner shell 101. After adjustment, if a dressing change is to be performed on a limb, the outrigger passes through the telescopic leg mechanism 2 and is positioned on the opposite side of the upper limit arc plate 204 and the lower flexible arc plate 205. If a dressing change is to be performed on the torso, the telescopic leg mechanism 2 is positioned on both sides of the torso, and the protective shell 1 and the telescopic inner shell 101 span the top of the torso, thus facilitating dressing changes in different positions and making it convenient to use.

[0044] In another implementation scheme, such as Figures 1-11As shown, rubber strips 605 are linearly and evenly distributed on the top of the outer sleeve 601 and the central column 603. The dimensions of the reinforcing telescopic column 608 are adapted to the dimensions of the inner mounting groove 606. The end of the reinforcing telescopic column 608 away from the outer sleeve 601 is fixedly installed inside the inner mounting groove 606 through a perforated plate. The opposite ends of the protective shell 1 and the telescopic inner shell 101 are threaded with three fixing bolts 105. The inner side of the inner mounting groove 606 away from the outer sleeve 601 is provided with threads adapted to the fixing bolts 105. The dimensions of the three fixing bolts 105 are adapted to the dimensions of the inner mounting groove 606 and the bolt hole 602. The protective shell 1 and the telescopic inner shell 101 are fixed to the inner mounting groove 606 and the bolt hole 602 by the fixing bolts 105 threaded connection.

[0045] Rubber strips 605 are evenly distributed on the top of the outer sleeve 601 and the central column 603 to increase friction for the rolling of the rubber hub sleeve 403 and the hub drive motor 402, preventing slippage and increasing the limiting effect. When the length of the telescopic support mechanism 6 is adjusted, the outer sleeve 601 and the central column 603 can be stretched. The central column 603 slides and is limited inside the central groove 604. The corner wrapping limit of the central groove 604 and the outer sleeve 601, together with the central extension of the central column 603, makes the top and bottom form a planar structure with the outer sleeve 601, which facilitates the planar rolling of the hub drive motor 402, the rubber hub sleeve 403 and the limiting support roller 404, thus ensuring stability during movement and adjustment. The reinforcing telescopic column 608 inside the inner mounting groove 606 is used to increase the load-bearing capacity at the connection between the central groove 604 and the central column 603, in conjunction with the central groove 604. The reinforced telescopic column 608 slides around the corners of the central column 603, ensuring relative structural stability. This means the sleeve of the reinforced telescopic column 608 extends into the inner mounting groove 606. This tight fit with the inner mounting groove 606 reduces vertical shear force. When the central column 603 moves, the inner mounting groove 606 moves outside the reinforced telescopic column 608. The inner mounting groove 606, through its opening and hollowed-out position, provides a fixed position and a pressure equalization position for the reinforced telescopic column 608, ensuring stability during adjustment and reducing mutual obstruction between structures. This increases structural strength and the stability of adjustment and movement. Furthermore, the reinforced telescopic column 608, along with the telescopic outer leg 201 and telescopic inner leg 202, can be replaced with an electrically controlled telescopic rod to add automatic adjustment capabilities. This facilitates the addition of other product specifications and intelligent control capabilities, leaving room for future improvements.

[0046] In another implementation scheme, such as Figures 1-11As shown, the bottom of the rubber hub sleeve 403 is in rolling contact with the top of the outer sleeve 601, the central column 603, and the rubber strip 605. The two ends of the hub drive motor 402 are fixedly installed on the inner wall of the rectangular frame 401. The limiting support rollers 404 are symmetrically and evenly distributed on the inner side of the rectangular frame 401. Three first limiting rings 405 are fixedly sleeved on the outer side of the limiting support rollers 404. Second limiting rings 406 are fixedly sleeved on the outer side of both ends of the limiting support rollers 404. The three first limiting rings 405 are rolled and engaged inside the limiting groove 607. The second limiting rings 406 are rolled and engaged on both sides of the outer sleeve 601. The outer side of the limiting support rollers 404 is in rolling contact with the bottom of the outer sleeve 601 and the central column 603.

[0047] The rubber hub sleeve 403 increases friction for the hub drive motor 402, facilitating relative stability. The mounting end of the hub drive motor 402 is fixed inside the rectangular frame 401 for subsequent stability. The limiting support roller 404 and the hub drive motor 402 are linearly distributed to form a triangular rolling support, which helps to keep the relative position of the rectangular frame 401 from shaking. The first limiting ring 405 engages with the limiting groove 607 and cooperates with the second limiting ring 406 and the two sides of the outer sleeve 601 to maintain the relative position of the limiting support roller 404. The limiting support roller 404 is fixed inside the rectangular frame 401 by the shaft seat, thus keeping the position of the rectangular frame 401 relatively stable and avoiding misalignment. Furthermore, there are limiting positions during extension and retraction, thus maintaining stability during adjustment and facilitating structural operation.

[0048] In another implementation scheme, such as Figures 1-12 As shown, the spraying mechanism 5 includes a mounting cylinder 501. A plastic rubber air guide tube 502 is fixedly inserted through the inner side of the mounting cylinder 501. The plastic rubber air guide tube 502 is U-shaped, with one end higher than the other, and passes through the side wall of the mounting cylinder 501. The outer end of the plastic rubber air guide tube 502 is connected to a one-way air inlet valve 503. A limit sealing ring 509 is fixedly sleeved on the inner side of the mounting cylinder 501. A water intake pipe 504 is connected to the bottom of the inner cavity of the mounting cylinder 501. The end of the water intake pipe 504 away from the mounting cylinder 501 is connected to a pressure pump 506 for pressurization. Pump 506 is fixedly installed inside rectangular frame 401. The output end of pressurizing pump 506 is connected to water outlet pipe 507. The other end of water outlet pipe 507 is connected to coil 505. The bottom of coil 505 is connected to several atomizing nozzles 508. Coil 505 is fixedly installed at the bottom of rectangular frame 401. Atomizing nozzles 508 are evenly distributed in a circular linear pattern at the bottom of coil 505. The top of protective shell 1 and telescopic inner shell 101 are both provided with through grooves 107. The size of mounting cylinder 501 is adapted to the size of through groove 107.

[0049] The plastic rubber air guide tube 502 is a flexible plastic pipe. When installing the medicine bottle 8, the plastic rubber air guide tube 502 is bent and inserted into the bottom of the medicine bottle 8. Then, before the medicine liquid flows out, the medicine bottle 8 is inverted inside the mounting cylinder 501 and fixed by rotation through the threaded connection. The limiting sealing ring 509 inside the mounting cylinder 501 limits the bottom of the medicine bottle 8. When the pressure pump 506 starts, it draws out the liquid inside the mounting cylinder 501 through the water pipe 504. At this time, the airflow enters the plastic rubber air guide tube 502 through the one-way air inlet valve 503 and equalizes the air pressure inside the medicine bottle 8. The medicine liquid is guided through the mounting cylinder 501 to the water pipe 504 and then through the pressure pump 506. 6. The water is pumped to the outlet pipe 507, and then guided through the outlet pipe 507 to the coil 505. Under the limiting condition of the coil 505, the water is guided into the interior of the atomizing nozzle 508. Through the atomization spray of the atomizing nozzle 508, the water is sprayed to the required location, which facilitates the spraying of physiological saline or medicine. It is convenient to configure multiple medicine bottles as needed, prepare multiple medicine bottles 8, and install and coordinate them as needed, which facilitates medicine changing operations and allows for the use of multiple medicines. If a solenoid valve is added to the connecting pipe of the atomizing nozzle 508, it is convenient to further enhance the intelligent control capability, facilitate point spraying according to the location, facilitate subsequent improvement and optimization via OTA, thereby reducing waste and increasing the effectiveness of use.

[0050] In another implementation scheme, such as Figures 1-11 As shown, the telescopic roller dipping mechanism 7 includes four high-precision electrically controlled telescopic rods 701. The four high-precision electrically controlled telescopic rods 701 are arranged in pairs, and a telescopic sleeve 702 is fixedly installed at the bottom end of each pair of high-precision electrically controlled telescopic rods 701. A flexible spring 711 is movably sleeved inside the telescopic sleeve 702. The two ends of the flexible spring 711 are respectively fixedly installed at the fixed part and the telescopic part of the telescopic sleeve 702. A mounting bracket 703 is fixedly installed at the telescopic end of the telescopic sleeve 702. A hollow support roller 704 is movably sleeved on the inner side of the mounting bracket 703 via a bearing. The hollow support roller 704 is hollow inside, with one end sealed and the other end open. A flexible silicone roller sleeve 705 is fixedly sleeved on the outer side of the hollow support roller 704. The flexible silicone roller sleeve 705 has an inverted trapezoidal wedge groove 706 on its outer side. Both the hollow support roller 704 and the flexible silicone roller sleeve 705 have several ventilation holes 710 inside. The ventilation holes 710 are evenly distributed in a circular linear pattern inside the hollow support roller 704 and the flexible silicone roller sleeve 705. The two ends of the ventilation holes 710 are respectively connected to the inside of the hollow support roller 704 and the outside of the flexible silicone roller sleeve 705. An L-bracket 707 is fixedly installed on the outer side of the mounting frame 703. A small motor 708 is fixedly installed on the inner side of the L-bracket 707. A fan blade 709 is fixedly installed at the output end of the small motor 708. The fan blade 709 is located inside the hollow support roller 704, and the specifications and dimensions of the fan blade 709 are compatible with the specifications and dimensions of the hollow support roller 704.

[0051] When the telescopic roller dipping mechanism 7 moves with the rectangular frame 401, if it absorbs the cleaned saline solution or medication, the high-precision electrically controlled telescopic rod 701 is activated to move downwards, causing the telescopic sleeve 702 and the bottom structure to move downwards as well. This causes the dipping cloth 9, installed on the outside of the flexible silicone roller sleeve 705, to contact the affected area. At this time, the flexible spring 711 inside the telescopic sleeve 702 provides tension and flexible support. When the dipping cloth 9 contacts the flexible silicone roller sleeve 705, it deforms, causing the telescopic sleeve 702 and the flexible spring 711 to change their extension and retraction, thereby allowing the flexible silicone roller sleeve 705 and the... The cloth 9 is applied to the affected area, allowing the liquid to be rolled and wiped, avoiding dynamic friction and reducing damage. After the liquid is applied, the small motor 708 is activated, which drives the fan blade 709 to rotate, causing airflow to flow inside the hollow support roller 704 and out through the vent 710. This creates a breathable effect on the cloth 9, allowing the skin to dry quickly and ensuring even airflow without causing direct airflow damage. The simultaneous airflow during the wiping process increases breathability, facilitates dressing changes, and enhances the overall effectiveness.

[0052] In another implementation scheme, such as Figure 6 and Figure 10 As shown, the dipping cloth 9 includes a gauze layer 901 and an absorbent cotton layer 902. The gauze layer 901 is fixedly installed on the top of the absorbent cotton layer 902. The dipping cloth 9 is movably sleeved on the outside of the flexible silicone roller sleeve 705, and the specifications and dimensions of the dipping cloth 9 and the wedge strip 10 are adapted to the specifications and dimensions of the inverted trapezoidal wedge groove 706.

[0053] The diaper cloth 9, in conjunction with the wedge-shaped retainer 10, is rolled onto the outside of the flexible silicone roller sleeve 705, with both ends of the diaper cloth 9 folded inside the inverted trapezoidal wedge groove 706. The wedge-shaped retainer 10 is then inserted, squeezing the folded portion of the diaper cloth 9 against the inverted trapezoidal wedge groove 706 to secure it. This facilitates replacement, cleaning, and disinfection. The overall structure is stable and easy to assemble and disassemble, allowing for convenient use after disinfection and mitigating the risk of infection. The gauze layer 901, on the outer side, is designed for easy contact with the skin and is made of natural or synthetic fibers, offering excellent absorbency and breathability. During dressing changes, the gauze can be soaked in saline solution to clean the wound or directly applied to absorb exudate and medication. Different sizes and textures of gauze are suitable for different types of wounds. For example, loose gauze is suitable for wounds with a lot of exudate, while finer gauze can be used to clean relatively clean wounds. Combined with absorbent cotton layer 902, it is convenient to absorb exudate and medicine. Made of degreased cotton, it is soft and highly absorbent. It is mainly used to soak up medicine or saline for local cleaning and disinfection of the wound. It can also be used to absorb small amounts of exudate. Combined with gauze layer 901 and flexible silicone roller sleeve 705, it increases the softness, reduces hard contact, and facilitates handling, thus facilitating dressing changes.

[0054] In another implementation scheme, such as Figure 5 and Figure 12 As shown, a threaded strip 801 is provided on the outer side of the mouth of the medicine bottle 8, and a silicone gasket ring 802 is fixedly installed on the outer side of the mouth of the medicine bottle 8. A fan-shaped groove 803 is opened on the inner side of the silicone gasket ring 802, and a threaded plate 804 is fixedly installed on the inner wall of the medicine bottle 8. The specifications and dimensions of the medicine bottle 8 and the threaded strip 801 are compatible with the specifications and dimensions of the mounting cylinder 501.

[0055] When installing the medicine bottle 8, the plastic rubber air guide tube 502 is inserted into the bottom of the medicine bottle 8. Then, before the liquid flows out, the medicine bottle 8 is inverted inside the mounting cylinder 501 and fixed by rotating the threaded strip 801 to the inner thread of the mounting cylinder 501. The silicone gasket ring 802 remains relatively stable due to its elasticity. Combined with the fact that the inside of the mounting cylinder 501 is a sealed space, the liquid inside the medicine bottle 8 remains relatively stable. When the pressure pump 506 draws water from the inside of the mounting cylinder 501 through the water pipe 504, the air pressure decreases and the liquid inside the medicine bottle 8 flows downward. By squeezing the silicone gasket ring 802, the gap of the fan-shaped groove 803 is deformed, and the liquid flows out. The air pressure is introduced into the medicine bottle 8 through the plastic rubber air guide tube 502 and the one-way air inlet valve 503, which facilitates the liquid to flow out when the pressure pump 506 draws water and keeps the liquid stable when it stops. This facilitates precise spraying of the medicine, makes it easy to control, prevents leakage, and increases the stability of control.
