Description
Technical Field
[0001] This utility model relates to the field of medical coupling agent application technology, and in particular to a coupling agent application device for hospital ultrasound. Background Technology
[0002] Ultrasound diagnosis is a non-invasive, painless, convenient, and intuitive examination method used in hospitals, especially B-mode ultrasound, which is widely used and has a significant impact, and is considered one of the four major medical imaging technologies along with X-ray, CT, and MRI. Most ultrasound examinations require the application of a coupling agent to the diagnostic site before the procedure. This sticky substance is called ultrasound coupling agent. The coupling agent maximizes the transmission of the ultrasonic energy generated by the probe through the skin and into the body, and then maximizes the transmission of the sound energy from within the body to the piezoelectric crystal of the probe. Furthermore, during the examination, to allow for comprehensive observation of organs, the probe needs to be moved in all directions—up, down, left, and right. The ultrasound coupling agent greatly reduces resistance during movement, making it convenient and easy to use.
[0003] Existing coupling agent application devices are not convenient for accurately controlling the amount of coupling agent squeezed out during use, and it is not easy to squeeze out the coupling agent. In addition, the coupling agent is cold in winter, and applying it directly to the body will cause cold discomfort. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing coupling agent application devices, such as the inconvenience in accurately controlling the amount of coupling agent squeezed out and the difficulty in squeezing out the coupling agent. Additionally, the coupling agent is cold in winter, and direct application to the body can cause discomfort due to low temperatures. Therefore, this invention proposes a coupling agent application device for hospital ultrasound.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for applying coupling agent for hospital ultrasound, comprising: a storage box, wherein the top of the storage box is provided with an inlet, and the top of the storage box is rotatably connected to a sealing cover at the position of the inlet; the storage box contains a water tank and a storage chamber, and the medical coupling agent enters the storage chamber through the inlet for storage.
[0006] As a further embodiment of this utility model, a motor is installed at the bottom of the storage box, a rotating shaft is rotatably connected inside the storage compartment, the output end of the motor is fixedly connected to the bottom of the rotating shaft, a stirring blade is fixed to the outside of the rotating shaft by a connecting rod, a hook is fixed to the bottom of the motor, and a stop is provided on the inner side of the hook by a torsion spring.
[0007] As a further embodiment of this utility model, the stirring blade is provided with a scraper and a vertical groove inside, the connecting rod is provided with a hollow groove inside, a spring is provided inside the hollow groove and a crossbar is slidably connected thereto, one end of the spring is fixedly connected to the crossbar, and one end of the crossbar is fixed with a pull rope, which passes through the connecting rod, the rotating shaft and the motor, and a horizontal column is fixed at the bottom of the pull rope.
[0008] As a further embodiment of this utility model, the storage box is provided with a placement block inside, the placement block is provided with a placement groove inside, the storage compartment is connected to a retractable discharge pipe, one end of the discharge pipe is connected to an applicator head, and the applicator head can be placed in the placement groove of the placement block.
[0009] As a further embodiment of this invention, the water tank contains a supersaturated salt solution, and an electric heating element is installed inside the water tank.
[0010] As a further embodiment of this utility model, a piston is provided inside the applicator head, a piston rod is fixed to the top of the piston, and a handle is fixed to the top of the piston rod.
[0011] As a further embodiment of this utility model, a waste discharge pipe is provided at the bottom of the storage compartment, which is used to discharge the waste inside the storage compartment when cleaning the storage compartment.
[0012] The present invention provides a coupling agent application device for hospital ultrasound, which has the following advantages:
[0013] 1. The storage box is installed on the ultrasound machine. The installation method can be bolted, but is not limited to bolt installation. Rotate the sealing cover and open the inlet. Then pour the medical coupling agent into the storage chamber through the inlet. All parts in the storage chamber meet medical standards. When the coupling agent temperature is low in winter, the electric heating tube can be activated, and the supersaturated salt solution in the water chamber will heat up. After the water chamber heats up, the coupling agent inside the storage chamber will be heated to a temperature suitable for the human body.
[0014] 2. Initially, the pull rope is tightened. After tightening, the crossbar retracts in the slot, and the spring is compressed. At this time, the scraper returns to the inside of the stirring blade, and the crossbar enters the hook through the stop to prevent the tightened pull rope from loosening. Then, the motor is started to drive the rotating shaft to rotate. When the rotating shaft rotates, it drives the stirring blade to rotate through the connecting rod. When the stirring blade rotates, it agitates the coupling agent. The coupling agent on the outside of the storage chamber is close to the water tank, so the coupling agent on the outside will be heated first. The coupling agent on the inside of the storage chamber takes longer to heat. Therefore, by agitating the coupling agent, the overall heating time of the coupling agent in the storage chamber can be shortened, which is conducive to rapid use. After the coupling agent is heated to a suitable temperature, it enters the inside of the application head through the discharge pipe. Then, the doctor presses the handle to lower the piston rod. When the piston rod lowers, the piston falls in the application head and automatically squeezes out the coupling agent and applies it to the examinee's abdomen. This extrusion method can effectively control the amount of coupling agent squeezed out each time, squeezing out only the amount needed. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.
[0025] A device for applying coupling agent for hospital ultrasound includes: a storage box 1, with an inlet 2 at the top of the storage box 1, and a sealing cover 3 rotatably connected to the top of the storage box 1 at the inlet 2; a water tank 4 and a storage chamber 5 inside the storage box 1; the medical coupling agent enters the storage chamber 5 through the inlet 2 for storage; a waste discharge pipe is provided at the bottom of the storage chamber 5 for discharging waste material inside the storage chamber 5 during cleaning; the water tank 4 contains a supersaturated salt solution; and an electric heating element 23 is installed inside the water tank 4. By rotating the sealing cover 3 and opening the inlet 2, the medical coupling agent is poured into the storage chamber 5 through the inlet 2. All parts inside the storage chamber 5 meet medical standards. When the coupling agent temperature is low in winter, the electric heating element 23 can be activated, and the supersaturated salt solution inside the water tank 4 will heat up, thus heating the coupling agent inside the storage chamber 5 to a temperature suitable for the human body.
[0026] Furthermore, a motor 6 is installed at the bottom of the storage box 1, and a rotating shaft 7 is rotatably connected inside the storage compartment 5. The output end of the motor 6 is fixedly connected to the bottom of the rotating shaft 7. A stirring blade 9 is fixed to the outside of the rotating shaft 7 via a connecting rod 8. A hook 10 is fixed to the bottom of the motor 6. A stop block 11 is provided on the inner side of the hook 10 via a torsion spring. A scraper 12 and a vertical groove 13 are provided inside the stirring blade 9. A slot is provided inside the connecting rod 8. A spring 14 is provided inside the slot and a crossbar 15 is slidably connected to it. One end of the spring 14 is fixedly connected to the crossbar 15. A pull rope 17 is fixed to one end of the crossbar 15. The pull rope 17 passes through the connecting rod 8, the rotating shaft 7, and the motor 6, and a horizontal column 18 is fixed to the bottom of the pull rope 17.
[0027] It can be concluded that in the initial state, the pull rope 17 is tightened. After the pull rope 17 is tightened, the crossbar 15 retracts in the empty groove and the spring 14 is compressed. At this time, the scraper 12 returns to the inside of the stirring blade 9, and the crossbar 18 enters the inside of the hook 10 through the stop block 11 to prevent the pull rope 17 from loosening after tightening. Then, the motor 6 is started to drive the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, it drives the stirring blade 9 to rotate through the connecting rod 8. When the stirring blade 9 rotates, it agitates the coupling agent. Since the coupling agent on the outside of the storage chamber 5 is close to the water tank 4, the coupling agent on the outside will definitely be heated first. The coupling agent on the inside of the storage chamber 5 takes a long time to heat. Therefore, by agitating the coupling agent, the overall heating time of the coupling agent in the storage chamber 5 can be shortened, which is conducive to rapid use.
[0028] Next, the storage box 1 is provided with a placement block 19 inside, and the placement block 19 is provided with a placement groove inside. The storage chamber 5 is connected to a retractable discharge pipe 21. One end of the discharge pipe 21 is connected to an application head 22. The application head 22 can be placed in the placement groove of the placement block 19. The application head 22 is provided with a piston 24 inside. A piston rod 25 is fixed to the top of the piston 24. A handle 26 is fixed to the top of the piston rod 25. The coupling agent, after being heated to a suitable temperature, enters the interior of the application head 22 through the discharge pipe 21. Then, the doctor presses the handle 26 to lower the piston rod 25. When the piston rod 25 lowers, the piston 24 descends inside the application head 22 and automatically squeezes out the coupling agent.
[0029] Working principle: Storage box 1 is installed on the ultrasound machine. The installation method can be bolt installation, but is not limited to bolt installation. Rotate the sealing cover 3 and then the feed port 2 is opened. Then, the medical coupling agent is poured into the storage chamber 5 through the feed port 2. All parts in the storage chamber 5 meet medical standards. When the coupling agent temperature is low in winter, the electric heating tube 23 can be started. Then, the supersaturated salt solution in the water tank 4 is heated. After the water tank 4 is heated, the coupling agent in the storage chamber 5 can be heated to a temperature suitable for the human body. Initially, the pull rope 17 is tightened. After the pull rope 17 is tightened, the crossbar 15 retracts in the slot, and the spring 14 is compressed. At this time, the scraper 12 returns to the inside of the stirring blade 9, and the crossbar 18 enters the inside of the hook 10 through the stop block 11 to prevent the tightened pull rope 17 from loosening. Then, the motor 6 is started to drive the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, it drives the stirring blade 9 to rotate through the connecting rod 8. When the stirring blade 9 rotates, it agitates the coupling agent. Since the coupling agent on the outside of the storage tank 5 is close to the water tank 4, the coupling agent on the outside will definitely be agitated first. Heating the coupling agent inside the storage chamber 5 takes a long time. Therefore, turning the coupling agent over can shorten the overall heating time of the coupling agent in the storage chamber 5, which is beneficial for quick use. After the coupling agent is heated to a suitable temperature, it enters the interior of the application head 22 through the discharge pipe 21. Then, the doctor presses the handle 26 to lower the piston rod 25. When the piston rod 25 lowers, the piston 24 lowers inside the application head 22, automatically squeezing out the coupling agent and applying it to the examinee's abdomen. This squeezing method can effectively control the amount of coupling agent squeezed out each time, squeezing out only the amount needed. After a certain period of use, the inner wall of the storage chamber 5 may be covered with coupling agent residue. At this time, remove the horizontal bar 18 from the hook 10, and then the spring 14 returns to its original position, moving the horizontal bar 15 back to its original position. Then, the scraper 12 passes through the vertical groove 13. At this time, one side of the scraper 12 is located outside the stirring blade 9 and in contact with the inner wall of the storage chamber 5. Then, pour clean water into the storage chamber 5 from the feed inlet 2. After that, the stirring blade 9 rotates, which drives the scraper 12 to rotate, which helps to scrape off the residue adhering to the inner wall of the storage chamber 5. Then, open the waste discharge pipe at the bottom of the storage chamber 5 to discharge the waste and complete the cleaning of the storage chamber 5.
[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
