Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to an ultrasound coupling agent application device. Background Technology

[0002] During ultrasound examination, the coupling agent serves as a crucial medium. Its function is to eliminate the air gap between the probe and the human skin, ensuring that ultrasound waves can effectively penetrate and transmit echo signals, thereby guaranteeing the clarity of the examination images and the accuracy of the diagnosis.

[0003] Currently, in clinical ultrasound applications, coupling gel application mainly relies on medical staff pouring the bottled coupling gel directly or applying it with a cotton swab. This traditional method has many drawbacks and can no longer meet the demands of modern ultrasound examinations for efficiency, hygiene, and standardization. Furthermore, the area covered by coupling gel on the skin is generally quite large to ensure coverage of the probe's examination area. However, coupling gel is usually quite cold, especially in low winter temperatures, and applying it over a large area of ​​skin can cause significant discomfort to the patient. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides an ultrasound coupling agent application device. Addressing the problems of traditional application methods relying on hand-held pouring or cotton swab application, which are cumbersome and inefficient, this invention employs a mechanical linkage control method for liquid dispensing. It features a detachable applicator with an integrated flow switch, opening / closing linkage, and controller, achieving continuous quantitative extrusion of the coupling agent without the need for manual pouring or swabbing. This solves the problems of cumbersome operation and low efficiency associated with traditional application methods. To address the issue of low coupling agent temperature causing discomfort to the patient during application, this invention creatively proposes a temperature regulation structure that integrates a water bath heating device and a drying system. The spiral heating tube in the water bath heating device achieves constant temperature heating of the coupling agent through heat exchange with the 37℃ water bath environment. At the same time, the PTC heating plate of the drying system can preheat the application component, so that the coupling agent and the application component can contact the skin at a temperature close to that of human body temperature. In order to solve the problems of uneven application, uncontrollable coverage, poor hygiene and easy cross-infection of traditional methods, a combination of vibration liquid dispensing and automatic cleaning and replenishment is adopted. The application component includes a vibration chamber, vibration ring and coil electromagnet, as well as a docking device that integrates cleaning, drying and replenishment functions. This achieves the technical effects of uniform application of coupling agent, precise and controllable coverage, and automatic cleaning, disinfection and sealing replenishment of the applicator after use.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides an ultrasound coupling agent application device, including an applicator, a docking device, a water bath heating device and a mounting platform. The docking device and the water bath heating device are both located above the mounting platform, and the applicator is mounted on the docking device.

[0006] Furthermore, the applicator includes a control component and an applicator component. The applicator component is mounted on the docking device and is fixedly connected to the lower end of the control component. The applicator is a handheld and detachable operating terminal that directly performs the functions of extruding and applying the coupling agent. It is the core component of the device that comes into contact with the patient.

[0007] Furthermore, the control component includes a grip shell, a flow switch, an opening and closing linkage, a liquid storage tank, a controller, a vibration pump, and a battery. The grip shell is mounted on the docking device, the flow switch is slidably mounted on the grip shell, the opening and closing linkage is slidably mounted inside the grip shell, and the liquid storage tank, controller, vibration pump, and battery are all located inside the grip shell. The liquid storage tank, controller, and vibration pump are connected in sequence. The control component integrates liquid supply, control, power supply, and gripping functions. Its internal mechanical and electrical structure realizes the linkage between the synchronous control circuit (vibration pump, coil electromagnet) and the liquid circuit (controller opening and closing) through a single flow switch, making operation intuitive and simple.

[0008] Furthermore, a sealing cover is slidably provided on the top of the liquid storage tank, and a sealing spring is connected to the lower end of the sealing cover. The sealing spring is also fixedly connected to the protrusion inside the liquid storage tank. The sealing cover and the sealing spring constitute the normally closed inlet of the liquid storage tank, which is only opened when docking with the replenishment system to prevent the coupling agent from leaking or becoming contaminated during handheld use.

[0009] Furthermore, the controller includes a control chamber, a closing slide chamber, an opening / closing connector, and a closing lock cylinder. The control chamber is located inside the grip shell, the closing slide chamber is located inside the control chamber, and the closing lock cylinder is slidably located inside the closing slide chamber. A vertical channel is provided inside the closing lock cylinder. The opening / closing connector is fixedly connected to one end of the closing lock cylinder. A closing spring is provided between the closing lock cylinder and the inner wall of the closing slide chamber. The upper end of the control chamber is connected to the liquid storage tank, and the lower end of the control chamber is connected to the inlet end of the vibration pump. The controller is a two-position, two-way valve controlled by a mechanical linkage. Its opening and closing state is directly determined by the operator's thumb movement, realizing precise and reliable manual control of the liquid circuit.

[0010] Furthermore, the inner end of the flow switch is provided with an inclined groove, and the flow switch is slidably connected to the opening and closing linkage through the inclined groove. The outer end of the opening and closing connector is provided with an inclined groove, and the opening and closing connector is slidably connected to the opening and closing linkage through the inclined groove. The inclined groove of the flow switch and the inclined groove of the opening and closing connector are in opposite directions. The opening and closing linkage is provided with a linkage baffle, and a return spring is sleeved on the opening and closing linkage. One end of the return spring is fixedly connected to the gripping housing, and the other end of the return spring is fixedly connected to the linkage baffle. This inclined groove linkage transmission mechanism converts the linear pressing action of the flow switch into the lateral sliding of the opening and closing connector, thereby driving the controller to open and close. It is a key mechanical conversion component connecting manual operation and internal hydraulic circuit control.

[0011] Furthermore, the application assembly includes an outer chamber and an application chamber. The outer chamber is fixedly connected to the bottom of the holding shell, and the application chamber is rotatably connected to the outer chamber. A fixed permanent magnet ring is provided at the upper end of the outer chamber. The application assembly is the output end of the device. Its internal vibration chamber is directly responsible for uniformly applying the coupling agent to the skin, while the outer chamber provides support and protection.

[0012] Furthermore, the coating chamber is equipped with a liquid chamber and a vibration chamber. The upper end of the liquid chamber is connected to the outlet end of the vibration pump. The vibration chamber is moltenly connected to the liquid chamber. The liquid chamber serves as a buffer and temporary storage area, receiving the coupling agent from the vibration pump. The vibration chamber, through its unique vibration ring structure, achieves the periodic and quantitative extrusion of the coupling agent.

[0013] Furthermore, a vibrating ring is rotatably installed inside the vibration chamber. A permanent magnet is mounted on the outer side of the vibrating ring, and a ring deflector is provided on the inner side of the vibrating ring. The N-pole of the permanent magnet points outward. A chamber deflector is provided inside the vibration chamber, and a deflector spring connects the chamber deflector and the ring deflector. The vibrating ring, permanent magnet, ring deflector, chamber deflector, and deflector spring together constitute an electromagnetically driven swing-type one-way valve. The coil electromagnet drives its periodic opening and closing, thereby achieving pulsed extrusion and uniform application of the coupling agent.

[0014] Furthermore, the inner side of the coating chamber is provided with coil electromagnets arranged in a ring. When the coil electromagnets are energized, the N-pole points inward. The coil electromagnets are the power source that drives the vibrating ring to oscillate periodically. By controlling the switching on and off of the power, a changing magnetic field is generated, which interacts with the permanent magnet to produce a repulsive force.

[0015] Furthermore, the liquid chamber is equipped with a pressure valve, and the pressure valve is slidably equipped with a pressure valve plate. A pressure spring is connected between the pressure valve plate and the inner wall of the top of the pressure valve. The pressure valve plays a role in balancing and buffering the system pressure. When the vibrating ring is closed, it stores the liquid pressure and releases the pressure to assist in extrusion when the vibrating ring is open, ensuring stable liquid output and protecting the internal pipeline.

[0016] Furthermore, the mounting platform has a double-layer structure. The upper layer of the mounting platform is equipped with a cleaning tank and a solvent tank, while the lower layer is equipped with a waste liquid tank. Casters are installed at the four corners of the bottom of the mounting platform, and an operating table is mounted on the top of the mounting platform. The double-layer mounting platform realizes functional zoning. The upper layer stores clean cleaning fluid and coupling agent, while the lower layer collects cleaning waste liquid. The casters give the entire device mobility, making it convenient to be used in different examination positions in the examination room.

[0017] Furthermore, the docking device includes a docking chamber, a docking mount, and a docking bracket. The docking chamber is located above the mount, the docking mount is located inside the docking chamber, the docking mount is provided with a docking groove, the docking bracket is slidably connected to the docking groove, and the docking mount is provided with a magnetic suction groove. The docking device provides a fixed parking, replenishment, and cleaning station for the applicator.

[0018] Furthermore, the docking chamber is equipped with a cleaning system and a drying system. The cleaning system includes a cleaning tank, a cleaning nozzle, a cleaning motor, a cleaning pump, a cleaning water supply pipe, and a wastewater drain pipe. The cleaning tank is located inside the docking chamber, and the cleaning nozzle is rotatably connected to the cleaning tank. The cleaning motor is located inside the docking chamber, and the cleaning nozzle is driven by the output end of the cleaning motor via a rubber belt. The cleaning pump is located inside the docking chamber. One end of the cleaning water supply pipe is connected to the cleaning nozzle, and the other end is connected to the cleaning tank. One end of the wastewater drain pipe is connected to the cleaning tank, and the other end is connected to the solvent tank. The cleaning system can automatically perform a circumferential spray cleaning of the application head after use, removing residual coupling agent and disinfecting it. It is a key automated module for ensuring cross-infection prevention and control.

[0019] Furthermore, the drying system includes a PTC heating plate and a drying fan. The PTC heating plate is installed inside the docking chamber, and the drying fan is installed on the side wall of the docking chamber. The air outlet of the drying fan is connected to the air inlet of the PTC heating plate, and the air outlet of the PTC heating plate is connected to the side wall of the cleaning tank. The drying system provides hot air drying after cleaning to quickly remove cleaning fluid residue from the surface of the application head, ensuring its immediate usability. It can also preheat the application head before application, further improving patient comfort.

[0020] Furthermore, the top of the docking chamber is equipped with a replenishment system, which includes a replenishment tube, a replenishment connector, and a photosensitive switch. The replenishment connector is located on the docking chamber, one end of the replenishment tube is connected to the replenishment connector, and the photosensitive switch is located on one side of the replenishment tube. The replenishment system is responsible for automatically and quantitatively replenishing the preheated coupling agent to the applicator when the reservoir is depleted. The photosensitive switch is used to detect whether the applicator is in place, thereby triggering the replenishment process.

[0021] Furthermore, the supplementary connector is provided with a connector sleeve, and a sliding connector is slidably provided inside the supplementary connector. The upper end of the sliding connector is slidably connected to the connector sleeve. A connector spring is provided between the sliding connector and the bottom inner wall of the supplementary connector. An annular electromagnet is provided at the bottom of the supplementary connector. The supplementary connector is an electromagnetically driven normally closed docking valve. When the applicator is correctly positioned and the photosensitive switch is triggered, the annular electromagnet is activated, attracting the sliding connector to move down, opening the sealing cover of the applicator's liquid storage chamber, and establishing a sealed supplementary channel.

[0022] Furthermore, the water bath heating device includes an insulation chamber, a heating base, a water bath chamber, a delivery pipe A, a delivery pump, a spiral heating pipe, and a delivery pipe B. The heating base is located above the mounting platform, the insulation chamber is located above the heating base, the water bath chamber is located inside the insulation chamber, the spiral heating pipe is located inside the water bath chamber, and the delivery pump is located outside the insulation chamber. One end of the delivery pipe A is connected to a solvent tank, and the other end of the delivery pipe A is connected to the inlet of the spiral heating pipe. One end of the delivery pipe B is connected to the outlet of the spiral heating pipe, and the other end of the delivery pipe B is connected to the other end of the replenishment pipe. The water bath heating device is the heating center of the coupling agent. It indirectly heats the coupling agent in the spiral pipe through the water bath, enabling it to be stably heated to a suitable temperature (such as 37°C), fundamentally solving the problem of patient discomfort caused by the cold coupling agent. It is a key module for achieving the core beneficial effects.

[0023] The beneficial effects of the ultrasound coupling agent application device provided in this solution are as follows: (1) In view of the shortcomings of the traditional method of operation being cumbersome and inefficient, the liquid dispensing structure is controlled by mechanical linkage consisting of a flow switch, an opening and closing linkage and a controller, which realizes the simplification and efficiency of operation. The operator only needs to hold the flow switch with one hand and press the flow switch with the thumb to simultaneously trigger the liquid circuit opening and closing and the vibration dispensing, eliminating a series of actions such as unscrewing the cap, pouring, recycling and wiping in the traditional method. (2) To address the drawback of the cold and uncomfortable feeling that the low-temperature coupling agent causes to the test subject, a dual temperature control structure with the water bath heating device and the drying system in the docking device is used to achieve precise optimization of the temperature of the coupling agent and the contact parts. The spiral heating tube indirectly and uniformly heats the coupling agent in a constant temperature water bath at 37℃; at the same time, the PTC heating plate of the drying system can preheat the coating component when it is parked. This design allows the temperature of the coupling agent to be stably controlled at 36.5℃-37.5℃ (fluctuation range ±0.5℃) during extrusion, and the temperature of the coating head contact surface is close to the human body temperature, thereby eliminating the cold feeling. (3) In view of the shortcomings of the traditional method, such as uneven coating, uncontrollable coverage and easy waste, a vibrating liquid outlet structure based on a vibrating chamber, a vibrating ring and a coil electromagnet is adopted, and combined with a rotatable coating chamber design, a breakthrough in coating quality and range control is achieved. The coil electromagnet drives the vibrating ring to open and close at high frequency and small amplitude, forming pulse extrusion, which makes the coating thickness of the coupling agent uniform. At the same time, the coating chamber can rotate relative to the outer chamber, allowing the operator to accurately adjust the coating area, thereby improving the matching accuracy between the coupling agent coverage area and the probe inspection area, and effectively avoiding the problem of insufficient or excessive waste of coupling agent. (4) In view of the shortcomings of traditional methods, such as poor hygiene and risk of cross-infection, a complete hygiene barrier is constructed by integrating an automated cleaning, drying, disinfection and sealing replenishment management system. After the applicator is put back in place after use, the cleaning system automatically sprays and scrubs the contact area with medical-grade cleaning solution. Then the drying system dries it with hot air. In addition, the replenishment system achieves sealed docking replenishment through an electromagnetically driven sliding joint and a sealing cover of the liquid storage tank, eliminating the possibility of the coupling agent being exposed to air and contaminated during storage and replenishment.

When the photosensitive switch 218 is turned off, it controls the annular electromagnet 222 to start. The annular electromagnet 222 attracts the bottom of the sliding joint 220, causing the sliding joint 220 to slide downwards. The sliding joint 220 compresses the joint spring 221, and the lower end of the sliding joint 220 pushes the sealing cover 108. The sealing spring 109 is compressed and shortened by the sealing cover 108. At this time, the sliding joint 220 connects to the liquid storage tank 106. The coupling agent enters the liquid storage tank 106 sequentially through the replenishment pipe 216, the joint sleeve 219, and the sliding joint 220. During replenishment... The transfer pump 305 pumps a fixed amount of coupling agent by default. The amount of coupling agent pumped is equal to the storage capacity of the liquid tank 106. After the coupling agent is replenished (i.e., the transfer pump 305 has finished pumping), the panel of the control table 405 displays a text prompt (the prompt content is implemented by programming, which is an existing method and is not limited). Then, the docking bracket 203 can be pulled out of the docking mount 202, and the applicator 1 on the docking mount 202 can be taken out. The replenished applicator 1 can be used for application. At the same time, the next applicator 1 can be installed in the same way. At least two sets of applicators 1 can be used for alternating application.During the reapplication process of the applicator 1, a cleaning and drying operation is automatically performed. First, the cleaning operation is performed, and the cleaning motor 212 and cleaning pump 213 are started at the same time. The cleaning motor 212 drives the cleaning nozzle 211 to rotate through the rubber belt. The cleaning pump 213 pumps the cleaning liquid in the cleaning tank 402 into the cleaning nozzle 211 through the cleaning water pipe 214. The cleaning liquid is sprayed onto the applicator component 102 at the bottom of the applicator 1 to disinfect and clean the main areas that come into contact with the patient's skin. The wastewater after cleaning is drained from the cleaning tank 210 into the wastewater drain pipe 215 and then into the waste liquid tank 401. After cleaning is completed, the cleaning motor 212 and cleaning pump 213 are turned off, and the PTC heating plate 223 and drying fan 224 are started to dry the cleaned applicator component 102. At the same time, the applicator component 102 can also be preheated.During the application process, the operator holds the outer casing 103 and presses the flow switch 104 with their index finger. This activates the vibration pump 117 and the coil electromagnet 127. The flow switch 104 slides inward and, through the inclined groove, drives the opening and closing connecting rod 105 to slide upward. The return spring 115 is compressed and shortened by the connecting rod baffle 116. Because the inclined groove of the opening and closing connector 112 is slidably connected to the opening and closing connecting rod 105, the upward sliding of the opening and closing connecting rod 105 drives the opening and closing connector 112 and the closing lock cylinder 114 to slide outward. This connects the inlet and outlet of the closing slide 111, while the closing lock cylinder 114 compresses the closing spring 115. The coupling agent shortens as it passes through the closed slide chamber 111 into the vibration pump 117, and is then pumped into the liquid chamber 120 by the vibration pump 117. After entering the liquid chamber 120, the coupling agent simultaneously fills the vibration chamber 121 and the pressure valve 128. After entering the pressure valve 128, the coupling agent pushes the pressure valve plate 129 outward, causing the pressure valve plate 129 to compress the pressure spring 130, thus shortening it to balance the pressure in the liquid chamber 120 and the vibration chamber 121. At the same time, the coil electromagnet 127 is activated. Initially, one edge of the coil electromagnet 127 is aligned with the center of the permanent magnet plate 123. The N-pole of iron 127 points inward, while the N-pole of permanent magnet 123 points outward. Due to the repulsion between like poles, permanent magnet 123 is affected by the magnetic force of coil electromagnet 127, causing vibrating ring 122 to rotate clockwise. During the rotation of vibrating ring 122, ring lever 124 and chamber lever 125 compress lever spring 126. At the same time, the channel of vibrating ring 122 connects with the channel at the bottom of vibrating chamber 121. At this time, the compressed spring force of pressure spring 130 is released, and the spring pressure and the pressure inside liquid chamber 120 discharge the coupling agent through the bottom of vibrating chamber 121. After that, coil electromagnet 127 is turned off. The extension of the paddle spring 126 causes the vibration chamber 121 to rotate and reset. The switching frequency of the coil electromagnet 127 is controlled by a built-in small PLC board. At this time, the coupling agent can be applied to the skin area of ​​the patient's test site. The annular groove at the bottom of the vibration chamber 121 ensures that the extruded coupling agent is uniform. The silicone heads at the bottom of the vibration chamber 121 and the outer chamber 118 maintain a certain distance between the vibration chamber 121 and the outer chamber 118 and the skin, allowing the coupling agent to be evenly applied to the patient's skin. After application, the other applicator 1 that has been replenished is removed, and the empty applicator 1 is replenished again.
