Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, and in particular to an automatic ultrasound probe coating machine and its operating method. Background Technology

[0002] Ultrasound examination is a diagnostic method that uses ultrasound waves emitted into the human body to capture reflected signals from tissues and convert them into images. These images are then combined with anatomical analysis. It offers advantages such as being non-invasive, radiation-free, real-time, and relatively inexpensive, making it an indispensable diagnostic tool in clinical practice. However, because the ultrasound probe is in close contact with the patient's body, situations may arise where there are skin infections or where ultrasound examinations need to be performed in sensitive areas such as the perineum. If the cleanliness of the ultrasound probe cannot be guaranteed, there is a high risk of cross-infection between patients.

[0003] Ultrasound probes play a crucial role in the medical field, especially in ultrasound examinations. To ensure the performance of ultrasound probes and extend their lifespan, regular maintenance and upkeep are necessary, with cladding being a vital component. Traditional cladding methods are mostly manual, which is not only inefficient but also poses hygiene and safety risks, such as potential probe contamination or damage due to improper handling.

[0004] A search revealed Chinese patent application number 201910554861.7, which discloses an automatic device for wrapping an ultrasonic probe. The device features a display screen on the front, a sealed chamber door on the upper surface, a coupling agent sealing chamber below the door (a hemispherical cavity), a nozzle with a nozzle switch below the coupling agent sealing chamber, an arc-shaped surface around the nozzle, a sensor A on the arc-shaped surface, a control panel on the upper part of the device, an inner chamber on the back, a back plate on the rear surface of the inner chamber, a wrapping motor mounted on the back plate, a planetary gear train connected to the output of the wrapping motor, and a plastic wrap roller connected to the output of the planetary gear train. A lithium battery compartment is located below the inner chamber, a U-shaped base is also located below the device, and a sensor B is located on the lower inclined surface of the device. This invention can automatically spray and wrap the ultrasonic probe with coupling agent, offering convenience, efficiency, and a good user experience.

[0005] The aforementioned device uses a planetary gear system to wrap the plastic wrap around the ultrasound probe. However, the wrapped plastic wrap is not further reinforced or restrained, and it is not sterilized during the wrapping process. Therefore, the plastic wrap may not be securely fixed, and it may easily move or fall off during the ultrasound probe's sliding examination on the patient's skin, failing to provide adequate protection. Furthermore, the lack of sterilization may cause infection when the unsterilized plastic wrap comes into contact with the patient's skin. Summary of the Invention

[0006] The existing technology has several technical problems. First, the plastic wrap used to wrap the ultrasound probe does not provide further reinforcement or restraint. Second, the plastic wrap is not sterilized during the wrapping process. This may result in the plastic wrap not being securely fixed, and the plastic wrap may easily move or fall off during the ultrasound probe sliding on the patient's skin, thus failing to provide good protection. Third, the plastic wrap without sterilization may cause infection when it comes into contact with the patient's skin.

[0007] Technical Concept: This application addresses the problems of existing technologies by providing a novel automatic ultrasonic probe coating machine. The unique technical concept of this application lies in the coordinated operation of a sun gear and planetary gear system to drive the coating mechanism, hot air film-fixing mechanism, and disinfection mechanism in a coordinated manner. This enables the simultaneous application of coupling agent to the inner side of the film and disinfectant to the outer side of the film during the coating process, while simultaneously heating and fixing the film. After coating is completed, the film is cut, achieving a convenient, fast, safe, and hygienic technical effect of protecting the ultrasonic probe.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This application provides an automatic ultrasonic probe laminating machine, including a laminating machine body and a probe holder disposed on the top of the laminating machine body. Two sets of pressure mechanisms and a film cutting mechanism are disposed on the side wall of the laminating machine body, and a linkage mechanism is disposed inside the laminating machine body. The linkage mechanism is correspondingly disposed with a laminating mechanism, a hot air film fixing mechanism and a disinfection mechanism.

[0009] Specifically, the coating machine body is a cylindrical cavity structure with a through top.

[0010] Furthermore, the linkage mechanism includes an outer gear ring disposed on the inner wall of the film-coating machine and a motor at the inner bottom. A sun gear is connected to the output end of the motor, and three planet gears are meshed on the sun gear. The three planet gears mesh with the outer gear ring.

[0011] Furthermore, the film coating mechanism includes a film winding roller, on which a film is wound and a retraction relief groove is opened at the bottom. A T-shaped connecting rod is slidably connected in the retraction relief groove. A spring is sleeved on one end of the T-shaped connecting rod, and a connecting seat is rotatably provided at the other end, with the end fixedly connected to any planetary gear. A limit block is rotatably connected to the top of the film winding roller. A coupling agent roller is connected between the connecting seat and the limit block. Both the coupling agent roller and the limit block are slidably engaged with the probe frame.

[0012] In particular, the retraction relief groove is a cuboid structure, and the bottom of the T-shaped connecting rod is a rounded rectangle structure, which allows the T-shaped connecting rod to move up and down in the retraction relief groove and ensures that the T-shaped connecting rod rotates synchronously with the film winding roller.

[0013] It should be noted that the coupling agent roller has a hollow structure and the coupling agent can permeate from the surface.

[0014] Furthermore, the coating mechanism also includes a coupling agent cavity opened on the probe frame and a delivery pipe connecting the coupling agent roller proximal pressure mechanism. Multiple connecting holes penetrating the coupling agent cavity are opened in the sliding groove at the bottom of the probe frame. Each of the multiple connecting holes is fitted with a pressing seat, which cooperates with the coupling agent roller.

[0015] Specifically, the pressing seat is an I-shaped disc mechanism, including an upper disc, a middle connecting rod and a lower disc. A cylindrical groove is opened in the center of the lower disc and the middle connecting rod, and three square slots are opened through the circumferential wall of the middle connecting rod. The coupling liquid enters the cylindrical groove through the square slots and finally flows into the interior of the coupling agent roller.

[0016] Furthermore, the hot air film-fixing mechanism includes a hot air blower, with a planetary gear rotatably connected to the bottom of the hot air blower and a limiting block rotatably connected to the top of the hot air blower. The limiting block slides into a limiting groove on the probe frame.

[0017] Furthermore, the disinfection mechanism includes a liquid storage chamber located within the outer gear ring. The liquid storage chamber is connected to another pressurization mechanism via a delivery pipe. The outer gear ring is provided with multiple seepage shafts. One end of each seepage shaft is connected to the liquid storage chamber, and the other end is connected to a probe holder. A coating roller is abutted against the side wall of each seepage shaft. One end of each coating roller is fixedly connected to a planetary gear, and the other end is rotatably connected to a limit block.

[0018] Furthermore, the pressurizing mechanism includes a pressurizing chamber disposed on the side wall of the film-coating machine body, a pressurizing cylinder disposed inside the pressurizing chamber, one end of the pressurizing cylinder being connected to the conveying pipe, and a pressurizing push rod being slidably connected to the other end, and a pressurizing spring being disposed between the pressurizing push rod and the inner wall of the pressurizing chamber.

[0019] Specifically, the film cutting mechanism includes an electric pusher blade disposed on the outer wall of the film-coating machine body and a blade groove extending through the inner wall of the film-coating machine body.

[0020] Preferably, the front wall of the film-coating machine is provided with a hatch.

[0021] An operating method for an automatic ultrasonic probe coating machine, characterized by comprising the following steps: S1: Insert the ultrasonic probe into the dialysis machine body through the probe holder; S2: The activation of the linkage mechanism drives the operation of the film covering mechanism, hot air mechanism, disinfection mechanism and film cutting mechanism; S3: During the operation of the film coating mechanism and the disinfection mechanism, the coupling agent and disinfectant are provided through the pressurization mechanism.

[0022] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a sun gear and planetary gear system to form a linkage mechanism, which in turn drives the film coating mechanism, hot air film fixing mechanism and disinfection mechanism to operate in a coordinated manner. This enables the application of coupling agent on the inside of the film and disinfectant on the outside of the film during the film coating process, while simultaneously heating and fixing the film. After the film coating is completed, the film is cut, achieving the technical effect of convenient, fast and safe protection of the ultrasonic probe.

[0023] 2. This invention uses a motor to drive the sun gear to rotate. Through the cooperation of the external gear ring set on the inner wall of the laminating machine with the sun gear, the three sets of planetary gears mesh with the sun gear and the external gear ring to achieve simultaneous revolution and rotation, thereby achieving fast and precise laminating, shortening the operation time and improving the overall efficiency.

[0024] 3. This invention features a film-winding roller for easy film winding, and a retraction groove at the bottom of the roller. A T-shaped connecting rod is slidably connected within the groove, with a spring fitted at one end. Pushing the film-winding roller compresses the spring, facilitating roller replacement and installation. A connecting seat is rotatably mounted at the other end of the T-shaped connecting rod, and the end is fixedly connected to any planetary gear. A limiting block is rotatably connected to the top of the film-winding roller, and a coupling agent roller connects between the connecting seat and the limiting block. Both the coupling agent roller and the limiting block slide against the probe holder. The coupling agent roller applies coupling fluid to the inside of the film during winding, ensuring the film adheres tightly to the probe, preventing air bubbles and wrinkles, and thus protecting the ultrasonic probe.

[0025] 4. This invention, through the creation of a coupling agent cavity on the probe holder and the provision of a delivery pipe connecting the coupling agent roller to the proximal end pressurizing mechanism, and the provision of multiple connecting holes penetrating the coupling agent cavity within a groove at the bottom of the probe holder, with pressing seats fitted into each connecting hole, engages with the coupling agent roller. The pressurizing mechanism pressurizes and delivers the coupling agent into the coupling agent cavity. Furthermore, the coupling agent roller contacts the pressing seats, thereby connecting the coupling agent cavity and the coupling agent roller, allowing the coupling agent to enter the coupling agent roller, achieving the technical effect of applying coupling agent to the inside of the film.

[0026] 5. This invention, by setting up a hot air blower and by rotatably connecting a planetary gear at the bottom of the hot air blower and a limiting block at the top, with the limiting block slidingly engaging with a limiting groove on the probe frame, achieves the technical effect of rapid and all-round heating and film curing by setting the limiting block and the rotational connection between the bottom of the hot air blower and the planetary gear. This is achieved by having the planetary gear revolve and rotate on its own axis while the hot air blower only revolves around the planetary gear, ensuring that the air outlet of the hot air blower is always aligned with the center of the film coating machine.

[0027] 6. This invention features a liquid storage chamber within an outer gear ring, connected to another pressurizing mechanism via a delivery pipe. Multiple percolation shafts are mounted on the outer gear ring, with one end connected to the liquid storage chamber and the other end connected to a probe holder. The pressurizing mechanism pressurizes and delivers disinfectant into the storage chamber, which then percolates through the percolation shafts. The percolated disinfectant is applied to a coating roller against the side wall of the percolation shaft. The coating roller then contacts the outer side of the film, thus achieving disinfection of the film. This effectively kills bacteria and viruses, reducing the risk of infection.

[0028] 7. The present invention achieves film cutting by using an electric pusher blade set on the outer side wall of the laminating machine. The electric pusher blade extends through the blade groove to cut the film, and the cut film tip will stick to the blade edge for easy reuse. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "front end", "rear end", "inner side", "outer side", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] The inventors discovered that during ultrasound examinations, disposable protective sleeves are currently used to protect the ultrasound probes from contamination and prevent cross-infection, thus avoiding contact between contaminated probes and patients. However, there are currently no suitable ultrasound probe sleeves available in clinical practice. Therefore, plastic wrap is often used as a protective sleeve, requiring two people to work together to apply coupling agent and then tear off a suitable size of plastic wrap to neatly wrap the probe surface, which is both time-consuming and labor-intensive. Alternatively, disinfectant wipes can be used to clean the probe after each use, which can be done by one person and saves time. However, ultrasound probes are precision instruments, and the organic solvents used in disinfectant wipes can damage the ultrasound probes, reducing their lifespan and increasing maintenance costs.

[0035] Based on the above findings, this application provides an automatic ultrasonic probe laminating machine, including a laminating machine body 1 and a probe holder 2 disposed on the top of the laminating machine body 1. Two sets of pressure mechanisms 3 and a film cutting mechanism 4 are disposed on the side wall of the laminating machine body 1, and a linkage mechanism 5 is disposed inside the laminating machine body 1. A laminating mechanism 6, a hot air film fixing mechanism 7 and a disinfection mechanism 8 are correspondingly disposed on the linkage mechanism 5. Example 1

[0036] Reference Figure 1-13 As shown, this application provides an automatic ultrasonic probe coating machine, including a coating machine body 1 and a probe holder 2 disposed on the top of the coating machine body 1. Two sets of pressure mechanisms 3 and a film cutting mechanism 4 are disposed on the side wall of the coating machine body 1, and a linkage mechanism 5 is disposed inside the coating machine body 1. A coating mechanism 6, a hot air film fixing mechanism 7 and a disinfection mechanism 8 are correspondingly disposed on the linkage mechanism 5.

[0037] Furthermore, the linkage mechanism 5 includes an outer gear ring 51 disposed on the inner wall of the film coating machine body 1 and a motor 52 at the inner bottom. A sun gear 53 is connected to the output end of the motor 52, and three planet gears 54 are meshed on the sun gear 53. The three planet gears 54 mesh with the outer gear ring 51.

[0038] Furthermore, the film coating mechanism 6 includes a film winding roller 61 on which a thin film 62 is wound. A connecting seat 66 is rotatably mounted on the film winding roller 61 and its end is fixedly connected to any planetary gear 54. A limiting block 67 is rotatably connected to the top of the film winding roller 61. A coupling agent roller 68 is connected between the connecting seat 66 and the limiting block 67. Both the coupling agent roller 68 and the limiting block 67 are slidably engaged with the probe holder 2.

[0039] In the specific operation, the planetary gear 54 rotates, which in turn drives the film roll 61 to rotate, thereby opening the film 62 so that the film 62 is rolled onto the ultrasonic probe.

[0040] In the above technical solution, the coating mechanism 6 also includes a coupling agent cavity 69 opened on the probe frame 2 and a delivery pipe 610 that connects to the proximal pressure mechanism 3 of the coupling agent roller 68. A plurality of connecting holes penetrating the coupling agent cavity 69 are opened in the sliding groove 21 at the bottom of the probe frame 2. Each of the plurality of connecting holes is fitted with a pressing seat 611, which cooperates with the coupling agent roller 68.

[0041] It should be noted that the top of the coupling agent roller 68 is a conical truncated structure, which facilitates the contact and pressing of the pressing seat 611 during the rotation along the slide groove 21, thereby realizing the connection between the coupling agent cavity 69 and the coupling agent roller 68.

[0042] Preferably, the hot air film-fixing mechanism 7 includes a hot air blower 71, with a planetary gear 54 rotatably connected to the bottom of the hot air blower 71 and a limiting block 67 rotatably connected to the top. The limiting block 67 is slidably engaged with the limiting groove 22 opened on the probe frame 2.

[0043] Specifically, by setting the limiting block 67 and the rotational connection between the bottom of the hot air blower 71 and the planetary gear 54, the hot air blower 71 only revolves while the planetary gear 54 revolves and rotates, so that the air outlet of the hot air blower 71 is always aligned with the center of the film coating machine body 1, achieving the technical effect of rapid and all-round heating and film solidification.

[0044] Furthermore, the disinfection mechanism 8 includes a liquid storage chamber opened in the outer gear ring 51. The liquid storage chamber is connected to another pressurization mechanism 3 through a delivery pipe 610. Multiple seepage shafts 81 are provided on the outer gear ring 51. One end of the seepage shaft 81 is connected to the liquid storage chamber, and the other end is connected to the probe frame 2. The side wall of the seepage shaft 81 abuts against a coating roller 82. One end of the coating roller 82 is fixedly connected to the planetary gear 54, and the other end is rotatably connected to a limit block 67.

[0045] It should be noted that the disinfectant in the storage chamber leaks to the surface through the seepage shaft 81. The rotation of the coating roller 82 causes the outer surface of the coating roller 82 to be coated with disinfectant. The disinfectant on the coating roller 82 is further coated onto the outside of the film 62 that wraps the probe, thereby achieving the disinfection treatment of the film 62.

[0046] Furthermore, the pressurizing mechanism 3 includes a pressurizing chamber 31 disposed on the side wall of the film-coating machine body 1. A pressurizing cylinder 32 is disposed inside the pressurizing chamber 31. One end of the pressurizing cylinder 32 is connected to the conveying pipe 610, and the other end is slidably connected to a pressurizing push rod 33. A pressurizing spring 34 is disposed between the pressurizing push rod 33 and the inner wall of the pressurizing chamber 31.

[0047] As an example, the film cutting mechanism 4 includes an electric pusher 41 disposed on the outer side wall of the film covering machine body 1 and a knife groove 42 that penetrates the inner side wall of the film covering machine body 1. Example 2

[0048] Based on Example 1, referring to Figure 13 As shown, in order to facilitate the installation and replacement of the film roll 61, a door 11 is provided on the front wall of the film coating machine body 1 and a retraction relief groove 63 is provided on the inner side of the film roll 61.

[0049] Specifically, a retraction relief groove 63 is provided at the bottom of the film roll 61, and a T-shaped connecting rod 64 is slidably connected in the retraction relief groove 63. A spring 65 is sleeved on one end of the T-shaped connecting rod 64, and a connecting seat 66 is rotatably provided on the other end, and the end is fixedly connected to any planetary gear 54.

[0050] During the specific operation, the hatch 11 is opened, and the film roll 61 is pushed to compress the spring 65. The T-shaped connecting rod 64 is pushed into the retraction relief groove 63, which facilitates the disassembly and replacement of the film roll 61.

[0051] Specific application examples: In cases requiring ultrasound-guided puncture or nerve block, all invasive procedures such as puncture and nerve block needle insertion must be disinfected with povidone-iodine. Povidone-iodine can damage the probe, and probes coated with coupling gel are difficult to disinfect, potentially contaminating sterile areas. Currently, clinically, common methods to address this issue include using disposable silicone gloves, disposable plastic wrap, or disposable sterile endoscope sleeves to wrap the coupling gel-coated probe. However, these methods all have some drawbacks: Disposable silicone gloves prevent the coupling agent from shifting, but they can affect the acoustic impedance of the ultrasound probe to some extent. Disposable plastic wrap is inconvenient, requiring at least two people to work together, and is easily damaged, causing the coupling agent to leak out. In clinical practice, the commonly used coupling agent is in a soft can, which needs to be manually squeezed onto the probe under pressure. When there is little coupling agent left in the can, it needs to be shaken forcefully to squeeze it out. Even in this case, some coupling agent at the bottom of the can is often wasted and discarded. This method is time-consuming, laborious, wasteful, and inconvenient.

[0052] Based on the above, this application provides an automatic ultrasonic probe laminating machine. In specific use, the door 11 is opened, and the film roll 61 with the film 62 wound on it is installed inside the laminating machine body 1. The ultrasonic probe is then inserted into the laminating machine body 1 through the probe holder 2. Initially, the head end of the film 62 is attached to the electric pusher 41. Further, the motor 52 is started, and the motor 52 drives the sun gear 53 to rotate. Through the engagement of the external gear ring 51 set on the inner wall of the laminating machine body 1 with the sun gear 53, the three sets of planetary gears 54 mesh with the sun gear 53 and the external gear ring 51 to achieve simultaneous revolution and rotation.

[0053] Furthermore, the rotation of the sun gear 53 and planet gear 54 drives the film coating mechanism 6, the hot air film fixing mechanism 7, and the disinfection mechanism 8 to operate.

[0054] Specifically, the planetary gear 54 rotates, which in turn drives the T-shaped connecting rod 64 to rotate. Through the cooperation of the T-shaped connecting rod 64 and the retraction relief groove 63, the film winding roller 61 is rotated, which in turn causes the film 62 to be pulled open and laid on the ultrasonic probe, thereby activating the electric pusher 41 to retract.

[0055] During the coating process, the coupling agent in the pressure cylinder 32 is transported to the coupling agent cavity 69 through the delivery pipe 610 under the action of the pressure spring 34. Further, as the coupling agent roller 68 rotates along the slide groove 21 opened on the probe frame 2, it abuts against the pressing seat 611, causing the pressing seat 611 to move upward, thereby connecting the pressing seat 611 with the coupling agent roller 68. This allows the coupling agent to enter the inner cavity of the coupling agent roller 68 and leak onto the surface of the coupling agent roller 68 and be coated onto the inner side of the film 62.

[0056] Furthermore, during the film coating process, through the setting of the limiting block 67 and the rotational connection between the bottom of the hot air blower 71 and the planetary gear 54, the hot air blower 71 only rotates while the planetary gear 54 revolves and rotates on its own axis, so that the air outlet of the hot air blower 71 is always aligned with the center of the film coating machine body 1, achieving the technical effect of rapid and all-round heating and film solidification.

[0057] Furthermore, the disinfectant in another pressure cylinder 32 is transported to the storage chamber through the delivery pipe 610 by the pressure spring 34, and further seeps to the surface through the seepage shaft 81. The outer surface of the coating roller 82 is coated with disinfectant by the rotation of the coating roller 82, and the disinfectant on the coating roller 82 is further coated to the outside of the film 62 covering the probe, thereby achieving the disinfection treatment of the film 62.

[0058] After lamination is completed, the electric pusher 41 is started to move forward along the blade groove 42 to cut the film 62. The cut end of the film 62 is pasted onto the electric pusher 41 for easy lamination in the next time.

[0059] It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this invention, and these should also be considered within the scope of protection of this invention. These modifications and improvements will not affect the effectiveness of the invention or the practicality of the patent.
