Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a protective device for an ultrasound probe used in anesthesia. Background Technology

[0002] The anesthesia ultrasound probe protection device mainly consists of a sterile isolation sleeve, a coupling agent replenishment structure, a fixation component, and auxiliary accessories. The sterile isolation sleeve, made of transparent medical polymer material, is the core component and isolates the probe from the patient's bodily fluids, preventing cross-infection. The coupling agent structure ensures clear imaging; the fixation component ensures a secure seal; and the auxiliary accessories include sterile packaging and sterilization indicators. Its uses are significant: it prevents cross-infection, protects the probe and extends its lifespan, ensures ultrasound imaging quality, and improves operational convenience through its disposable design and anti-slip structure. It is suitable for various anesthesia scenarios such as nerve blocks and vascular punctures, and is an important tool in modern minimally invasive anesthesia techniques.

[0003] Publication number CN114795284A discloses a medical ultrasound probe device with a protective structure, including an ultrasound probe body and a protective shell body fitted onto the ultrasound probe body. The protective shell body consists of a sheath and a protective cover. A coating assembly is provided on the sheath at the head of the ultrasound probe body. A coupling agent storage box for applying coupling agent to the surface of the protective film output by the coating assembly is installed on the sheath. The protective cover is fastened to the sheath outside the protective film. This device allows for convenient operation by holding the ultrasound probe body with the grip groove on the sheath, effectively protecting the ultrasound probe body from drop and damage. By setting the coating assembly, a protective film coated with coupling agent is formed between the ultrasound probe body and the patient's examination site. The protective film can be quickly replaced by rotating the rewind drum. During ultrasound examination, it offers high safety, avoids cross-infection, eliminates the need for separate application of coupling agent, and is convenient and quick to operate.

[0004] The aforementioned protective device for anesthesia ultrasound probes has the following shortcomings: the coupling agent is applied to the protective film through the coating component, which easily leads to uneven application, affecting the quality of ultrasound imaging. At the same time, it is impossible to monitor the remaining amount of protective film on the unwinding drum in real time, and the protective film often runs out midway. The thickness of the protective film gradually decreases with use, resulting in poor contact between the coating roller and the protective film, further aggravating the problem of uneven application of coupling agent. In addition, the protective film is prone to sticking to the unwinding drum, and jamming and folding may occur during release, affecting the stability of use. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a protective device for an anesthesia ultrasound probe to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: a protective device for an anesthesia ultrasound probe, comprising a protective shell, an unwinding mechanism disposed inside the protective shell, a detection mechanism disposed on the side of the unwinding mechanism, and a connecting mechanism fixedly connected inside the protective shell; The unwinding mechanism includes an unwinding drum driven by a motor. A first pulley is fixedly connected to the side of the unwinding drum, and a second pulley is located at the bottom of the first pulley. A belt is installed on the first and second pulleys. A gear is fixedly connected to the side of the second pulley, and a rack is meshed with the top of the gear. A coupling agent storage box is located on the side of the rack, and the side of the rack is located in and movably connected to the coupling agent storage box. A protrusion is fixedly connected to the unwinding drum. The testing mechanism includes a connector, on the side of which a first spring and an upper connecting block are fixedly connected. The first spring is sleeved on the upper connecting block, and its other end is fixedly connected to the protective shell. A display panel with scales is fixedly connected to the top of the upper connecting block. A lower connecting block is fixedly connected to the bottom of the upper connecting block. A connecting bracket is fixedly connected to the side of the lower connecting block. An application roller and a positioning shaft are rotatably connected to the connecting bracket. A display groove is provided on the protective shell, located outside the display panel, for displaying the scales on the display panel.

[0007] Furthermore, a handle is fixedly connected to the protective shell. The handle is made of silicone and has several anti-slip textures. The silicone material, with its high coefficient of friction, softness, skin-friendliness, and easy-to-clean properties, combined with the anti-slip textures, enhances the grip friction, preventing the device from slipping when the hands are wet or have coupling gel on them. This prevents damage to the probe, secondary injury to the patient, and image displacement, ensuring operational safety and accuracy. At the same time, the micro-elasticity of the silicone and the pressure-dispersing effect of the anti-slip textures can reduce hand fatigue during prolonged use, improve comfort, and also help buffer impact forces, extending the device's lifespan and providing practical support for the precise operation of anesthesia ultrasound.

[0008] Furthermore, a roller scraper is fixedly connected to the bottom of the connecting bracket, and a second spring is fixedly connected to the bottom of the lower connecting block. The bottom of the second spring is fixedly connected to the protective shell.

[0009] Furthermore, the protective shell is internally provided with a take-up drum, a scraping mechanism, and a positioning roller. The take-up drum is driven by a motor. The scraping mechanism is fixedly connected to the protective shell. The positioning roller is rotatably connected to the protective shell. A protective film is wound on the unwinding drum and the take-up drum. The protective film is disposed between the coating roller and the positioning roller.

[0010] Furthermore, the scraping mechanism includes a collection box, a connecting platform and a No. 3 spring are fixedly connected to the collection box, a scraper is fixedly connected to the top of the No. 3 spring, a number of locking blocks are fixedly connected to the connecting platform, and a protective film is set at the top of the scraper and the locking blocks.

[0011] Furthermore, the coupling agent storage box includes a storage box body, the storage box body has a storage cavity inside, the storage box body has an extrusion cavity at the top, and a piston rod is fixedly connected to the side of the rack, with the piston rod and the storage box body having an inclination angle of 75 degrees.

[0012] Furthermore, the connecting mechanism includes a device housing with a lower cavity and an upper cavity inside. An elastic plate is fixedly connected inside the device housing, and a connecting plate is fixedly connected to the elastic plate. Under the upward pulling force of the connecting plate, the deformable section in the middle of the elastic plate bends upward. The connecting plate is movably connected to the device housing, and the connection is sealed by a sealing ring. A connecting pipe is fixedly connected to the device housing, and the connecting pipe passes through the protective housing and communicates with the outside. The connecting pipe is mainly used to balance the air pressure in the lower cavity and the upper cavity inside the device housing. After the cover is opened, the elastic plate tends to move the connecting plate downward due to its own elasticity, and the connecting pipe can control the gas discharge speed in the cavity. By slowly releasing the gas, the rebound speed of the elastic plate is slowed down, thereby achieving the delayed downward movement of the probe body.

[0013] Furthermore, the protective housing has an internal cavity, and the probe body is movably connected to the cavity. A cover plate is provided at the bottom of the protective housing, and the cover plate is fixed to the protective housing by a threaded connection.

[0014] Beneficial effects: 0. This protective device for anesthesia ultrasound probes uses a motor-driven unwinding drum to release the protective film and a rewinding drum to simultaneously rewind the old film, achieving automatic replacement of the protective film and avoiding the risk of cross-infection. When the unwinding drum rotates, it drives the piston rod to squeeze the coupling agent storage box through pulleys, gears, and racks. The 75-degree tilt design allows the coupling agent to be squeezed out evenly and synchronously with the release of the protective film, solving the problems of tedious and uneven manual application, ensuring image quality, protecting the outer shell and connecting mechanism to ensure stable operation of components, and the overall automated operation greatly improves the safety, convenience, and efficiency of anesthesia ultrasound operation.

[0015] 1. This protective device for anesthesia ultrasound probes consists of a connector, a first spring, an upper connecting block, and a display panel that work together. The display panel scale changes can be observed through the display slot, allowing real-time monitoring of the remaining protective film on the unwinding drum for timely replacement. The upper connecting block, lower connecting block, second spring, and connecting bracket drive the application roller and positioning shaft to adjust their height according to the thickness of the protective film, ensuring that the application roller always maintains good contact with the protective film and guaranteeing image quality. The protrusion on the unwinding drum causes the connector to drive the application roller and positioning shaft to vibrate slightly, generating a "peeling force" to ensure the smooth release of the protective film.

[0018] 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.

[0019] Please see Figure 1 , Figures 3-5 A protective device for an anesthesia ultrasound probe includes a protective shell 1, an unwinding mechanism 2 is provided inside the protective shell 1, a detection mechanism 3 is provided on the side of the unwinding mechanism 2, and a connecting mechanism 8 is fixedly connected inside the protective shell 1. The unwinding mechanism 2 includes an unwinding drum 201, which is driven by a motor. A first pulley 202 is fixedly connected to the side of the unwinding drum 201. A second pulley 204 is provided at the bottom of the first pulley 202. A belt 203 is installed on the first pulley 202 and the second pulley 204. A gear 205 is fixedly connected to the side of the second pulley 204. A rack 207 is meshed with the top of the gear 205. A coupling agent storage box 208 is provided on the side of the rack 207. The side of the rack 207 is located in the coupling agent storage box 208 and is movably connected to the coupling agent storage box 208. A protrusion 206 is fixedly connected to the unwinding drum 201.

[0020] The coupling agent storage box 208 includes a storage box body 2081, a storage cavity 2082 is provided inside the storage box body 2081, an extrusion cavity 2083 is provided on the top of the storage box body 2081, and a piston rod 209 is fixedly connected to the side of the rack 207. The angle between the piston rod 209 and the storage box body 2081 is seventy-five degrees.

[0021] A handle 11 is fixedly connected to the protective shell 1. The handle 11 is made of silicone and has several anti-slip textures. The silicone material has a high coefficient of friction, is soft and skin-friendly, and is dirt-resistant and easy to clean. Combined with the anti-slip textures, it enhances the grip friction and prevents the device from slipping when the hands are wet or have coupling gel on them. This prevents damage to the probe, secondary injury to the patient, and image displacement, ensuring operational safety and accuracy. At the same time, the micro-elasticity of the silicone and the pressure-dispersing effect of the anti-slip textures can reduce hand fatigue during long-term holding, improve comfort, and also help to buffer impact forces, extend the life of the device, and provide practical support for the precise operation of anesthesia ultrasound (such as nerve block and vascular puncture).

[0022] In this embodiment, it is important to note that the motor-driven unwinding drum 201 releases the protective film 4, simultaneously driving the take-up drum 5 to rewind the old film, thus achieving automatic replacement of the protective film 4 and avoiding the risk of cross-infection. Simultaneously, as the unwinding drum 201 rotates, it is driven by pulley 202, belt 203, pulley 204, gear 205, and rack 207, pushing the piston rod 209 to compress the coupling agent storage box 208. The 75-degree angle between the piston rod 209 and the storage box 2081 ensures that the coupling agent is uniformly extruded synchronously with the release of the protective film 4, solving the problems of tedious manual application and uneven distribution, and ensuring image quality. The silicone grip 11 on the protective shell 1 enhances operating comfort and reduces hand fatigue. The protective shell 1 and the connecting mechanism 8 ensure stable operation of the components, and the overall structure achieves automated operation, significantly improving the safety, convenience, and efficiency of anesthesia ultrasound operations.

[0023] The specific working principle is as follows: The unwinding drum 201 is driven by a motor to rotate, slowly releasing the protective film 4 wound on it. The take-up drum 5 on the other side is driven by a motor to rotate and take back the protective film 4, thereby replacing different sections of the protective film 4 and forming a new unused protective film 4 at the cover plate 12. While the unwinding drum 201 is rotating, the gear 205 is driven to rotate through the transmission of the first pulley 202, belt 203 and the second pulley 204. The gear 205 drives the rack 207 meshing with it to move linearly. The rack 207 pushes the piston rod 209 to move towards the coupling agent storage box 208, squeezing out the coupling agent inside the coupling agent storage box 208, so as to achieve continuous and uniform extrusion of the coupling agent.

[0024] Please see Figures 1-2 The testing mechanism 3 includes a connector 301. A first spring 302 and an upper connecting block 303 are fixedly connected to the side of the connector 301. The first spring 302 is sleeved on the upper connecting block 303 and the other end of the first spring 302 is fixedly connected to the protective shell 1. A display panel 310 is fixedly connected to the top of the upper connecting block 303. The display panel 310 is provided with a scale. A lower connecting block 304 is fixedly connected to the bottom of the upper connecting block 303. A connecting bracket 305 is fixedly connected to the side of the lower connecting block 304. An applicator roller 308 and a positioning shaft 309 are rotatably connected to the connecting bracket 305. A display groove is opened on the protective shell 1. The display groove is located outside the display panel 310 and is used to display the scale of the display panel 310.

[0025] A roller scraper 306 is fixedly connected to the bottom of the connecting bracket 305, and a second spring 307 is fixedly connected to the bottom of the lower connecting block 304. The bottom of the second spring 307 is fixedly connected to the protective shell 1.

[0026] In this embodiment, it is important to specifically explain that: the connector 301, spring 302, upper connecting block 303, and display panel 310 work together to allow observation of scale changes on the display panel 310 through the display slot, enabling real-time monitoring of the remaining amount of protective film 4 on the unwinding drum 201. This solves the problem of unclear protective film remaining amount and facilitates timely replacement. The upper connecting block 303, lower connecting block 304, spring 307, and connecting bracket 305 drive the coating roller 308 and positioning shaft 309 to adjust their height according to the thickness of the protective film 4, ensuring the coating roller... 308 maintains good contact with the protective film 4, solving the problem of uneven application of coupling agent caused by changes in the thickness of the protective film and ensuring imaging quality; the protrusion 206 on the unwinding drum 201 causes the connector 301 to drive the coating roller 308 and the positioning shaft 309 to vibrate slightly, generating a "peeling force", which solves the problem of poor release and folding caused by the adhesion between the protective film 4 and the unwinding drum 201, ensuring smooth release of the protective film; the roller scraper 306 can assist in sorting the coupling agent, improving the coating effect, and improving the overall stability and reliability of the device.

[0027] The working principle of the device is as follows: As the unwinding drum 201 continuously releases the protective film 4, the thickness of the protective film 4 wound on the unwinding drum 201 continuously decreases. The connector 301 abuts against the side of the protective film 4 on the unwinding drum 201. As the thickness of the protective film 4 decreases, the first spring 302 drives the connector 301 to move towards the unwinding drum 201. The connector 301 drives the upper connecting block 303 to move. The upper connecting block 303, on the one hand, drives the display panel 310 to move towards the unwinding drum 201. The movement of the display panel 310 can be observed through the display slot, thereby determining the remaining amount of protective film 4 on the unwinding drum 201. On the other hand, the upper connecting block 303... The movement causes the lower connecting block 304 to move upward under the action of the second spring 307, thereby raising the height of the coating roller 308 and the positioning shaft 309. As the thickness of the protective film 4 on the unwinding drum 201 decreases, its height will also change upward. The coating roller 308 rotates and contacts the protective film 4, applying pressure to the protective film 4, thereby spreading the coupling agent evenly on the protective film 4. Through the cooperation of the upper connecting block 303, the lower connecting block 304 and the second spring 307, the relative position of the coating roller 308 and the protective film 4 does not change, ensuring that the uniformity of the coupling agent application on the protective film 4 remains consistent during use.

[0028] The unwinding drum 201 is fixedly connected to a protrusion 206, which causes the protective film 4 at the protrusion 206 to bulge. When the unwinding drum 201 rotates, the protrusion 206 drives the connector 301 to move a short distance toward the display panel 310. After passing the protrusion 206, the connector 301 returns to its original position. This movement causes the lower connector 304 and the coating roller 308 and positioning shaft 309 below it to vibrate during coating. The slight vibration generates a slight "peeling force" on the film surface, allowing the protective film to detach smoothly from the surface of the drum, avoiding "sudden release" or "partial folding" caused by adhesion.

[0029] Please see Figure 6 The protective shell 1 is equipped with a take-up drum 5, a scraping mechanism 6 and a positioning roller 7. The take-up drum 5 is driven by a motor. The scraping mechanism 6 is fixedly connected to the protective shell 1. The positioning roller 7 is rotatably connected to the protective shell 1. A protective film 4 is wound on the unwinding drum 201 and the take-up drum 5. The protective film 4 is placed between the coating roller 308 and the positioning shaft 309.

[0030] The scraping mechanism 6 includes a collection box 601, a connecting platform 603 and a No. 3 spring 605 are fixedly connected to the collection box 601, a scraper 602 is fixedly connected to the top of the No. 3 spring 605, and a number of locking blocks 604 are fixedly connected to the connecting platform 603. A protective film 4 is set at the top of the scraper 602 and the locking blocks 604.

[0031] In this embodiment, it should be specifically explained that: the card block 604 is used to break the dried coupling agent structure, and then the coupling agent is scraped off by the scraper 602. The coupling agent falls into the collection box 601 and is collected. The third spring 605 makes the scraper 602 always maintain an upward pressure on the protective film 4, which makes it easier to scrape off the coupling agent.

[0032] Please see Figure 6 The connecting mechanism 8 includes a device housing 801. The device housing 801 has a lower cavity 802 and an upper cavity 803 inside. An elastic plate 805 is fixedly connected inside the device housing 801. A connecting plate 804 is fixedly connected to the elastic plate 805. Under the upward pulling force of the connecting plate 804, the deformable section in the middle of the elastic plate 805 is bent upward. The connecting plate 804 is movably connected to the device housing 801 and the connection is sealed by a sealing ring. A connecting pipe 13 is fixedly connected to the device housing 801. The connecting pipe 13 passes through the protective housing 1 and communicates with the outside.

[0033] The protective housing 1 has an internal cavity 9, and the probe body 10 is movably connected to the cavity 9. The bottom of the protective housing 1 is provided with a cover plate 12, which is fixed to the protective housing 1 by a threaded connection.

[0034] In this embodiment, it should be specifically explained that when the cover plate 12 is connected to the protective shell 1, the cover plate 12 drives the connecting plate 804 to move upward, and the connecting plate 804 drives the elastic plate 805 to move upward. The two ends of the elastic plate 805 are fixed to the device shell 801, and the device shell 801 is fixed to the protective shell 1, so that the elastic plate 805 is deflected upward. After the cover plate 12 is opened, the elastic force of the elastic plate 805 causes the connecting plate 804 to move downward. At the same time, the connecting plate 804 drives the probe body 10 to move downward, bringing the probe body 10 to the position of the protective film 4. The connecting tube 13 is mainly used to balance the air pressure of the lower cavity 802 and the upper cavity 803 inside the device shell 801. Through the slow release of air by the connecting tube 13, the probe body 10 moves downward with a delay after the cover plate 12 is opened. During this process, the protective film 4 is replaced by the unwinding mechanism 2 and the winding drum 5.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
