An obstetric ultrasound examination aid

Abstract

This utility model relates to the field of medical device technology and discloses an obstetric ultrasound examination auxiliary device, including a cylindrical body. The bottom of the cylindrical body is provided with a support component for supporting it, and the middle of the bottom end of the cylindrical body is provided with a discharge component for discharging coupling agent. The top end of the cylindrical body is threadedly connected to a threaded cap, and the threaded cap is slidably connected to a pull rod. The bottom of the pull rod has two storage slots, and the inside of the storage slots is a limiting block that limits the pull rod. By opening the threaded cap, coupling agent can be added into the cylindrical body. By pulling the pull rod, the piston is compressed to the energy storage spring, which can store energy. After the threaded cap is installed, the limiting block is stored in the storage slot, which can ensure that the pull rod slides on the threaded cap. When the coupling agent is taken out by the discharge component, the energy storage spring can release energy and push the piston, thereby automatically squeezing out the coupling agent. The structure is simple and not easily damaged.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary device for obstetric ultrasound examination. Background Technology

[0002] Ultrasound examination, usually referring to B-mode ultrasound, is a medical examination method that utilizes the properties of ultrasound waves reflecting, absorbing, and scattering within the human body. An instrument receives these echo signals and converts them into images to observe internal structures. In obstetrics, ultrasound examinations are used to assess fetal growth and development as well as the health of the mother's uterus. Ultrasound coupling gel plays several important roles in ultrasound examinations. First, it eliminates air between the probe and the skin, ensuring that ultrasound waves can smoothly penetrate the skin and enter internal tissues, resulting in clearer and more accurate images. Second, it acts as a lubricant, reducing friction between the probe and the skin, making it easier for the probe to slide on the skin and reducing discomfort for the patient.

[0003] The "Coupling Agent Spraying Device for Obstetric Ultrasound Examination" disclosed in application number "202020878031.8" includes a cylinder, a threaded rod, and a fixing block. A connecting block is fixedly connected to one side of the fixing block, and a motor is provided on one side of the connecting block. A transmission rod is movably connected to the output end of the motor. A first gear is movably connected to one end of the transmission rod, a second gear meshes with one side of the first gear, a rotating rod is movably connected to the middle of the second gear, a third gear is movably connected to one end of the rotating rod, and a fourth gear meshes with one side of the third gear. This coupling agent spraying device for obstetric ultrasound examination is convenient for staff to handle and for medical personnel to operate. The transparent glass allows medical personnel to easily view the applied coupling agent dosage, and the cap prevents dust from entering the cylinder when not in use, thus affecting the use of the coupling agent.

[0004] However, the above method still has the following drawbacks: the coupling agent can be squeezed out by compressing the rubber piston in the cylinder, but a motor and gear drive the threaded rod to realize the transmission of the rubber piston. The structure is complicated, easy to be damaged, and increases the cost. It is also not convenient to heat the coupling agent. In the cold season, the coupling agent at room temperature will bring patients a cold and uncomfortable feeling. Utility Model Content

[0030] In this embodiment, preferably, the top of the cylinder 1 is fixedly provided with threads, the inner wall of the threaded cover 6 is threadedly connected to the threads, the middle of the top of the threaded cover 6 is provided with a rod groove 13, the pull rod 7 is slidably connected to the inside of the rod groove 13, and both sides of the top of the threaded cover 6 are provided with venting grooves 14 that communicate with the inside of the rod groove 13. The rod groove 13 can guide the pull rod 7, and the venting grooves 14 can ensure the consistency of air pressure inside and outside the threaded cover 6.

[0031] In this embodiment, preferably, a pull button 11 is fixedly provided at the top end of the pull rod 7. The pull button 11 is located outside the cylinder 1. Several anti-slip grooves are formed on the surface of the pull button 11. A screw 12 is fixedly provided at the bottom end of the pull rod 7. The diameter of the screw 12 is smaller than the diameter of the pull rod 7. A threaded groove 16 is formed in the middle of the top end of the piston 15. The screw 12 is threadedly connected to the inside of the threaded groove 16. The screw 12 and the threaded groove 16 facilitate the installation and disassembly of the piston 15. Two grooves 17 are formed on the surface of the piston 15. A sealing ring 18 is engaged inside the grooves 17. The sealing ring 18 is slidably connected to the inner wall of the cylinder 1. The surface of the sealing ring 18 is coated with an anti-aging agent. The sealing ring 18 can ensure the sealing between the piston 15 and the inner wall of the cylinder 1.

[0032] In use, first loosen the threaded cap 6 and open it. Then add coupling agent into the cylinder 1. Next, pull the lever 7 to compress the energy storage spring 19 with the piston 15. The energy storage spring 19 can store energy. Then unfold the limiting block 9 and make it fit against the top of the threaded cap 6 to keep the energy storage spring 19 in a compressed state. Then put the piston 15 into the cylinder 1 and tighten the energy storage spring 19. Finally, put the limiting block 9 into the storage groove 8. The energy storage spring 19 can transmit pressure to the coupling agent inside the cylinder 1 through the piston 15. The sealing ring 18 can maintain the seal between the piston 15 and the cylinder 1. By turning the lever 7 through the pull button 11, the lever 7 can be disassembled and removed from the piston 15 without occupying external space.

[0033] After the coupling agent is loaded inside the cylinder 1, the ball head 402 of the discharge component 4 can seal the threaded pipe 401. Under the pressure of the energy storage spring 19 and the piston 15, the leakage of the coupling agent can be prevented. By placing the bottom of the cylinder 1 on the support 301 of the support component 3, the support 301 can limit the cylinder 1 through the limiting groove 303. The setting of the placement groove 302 can ensure the placement space of the anti-slip knob 405.

[0034] When an ultrasound examination of the fetus is required, the cylinder 1 is removed from the support 301. The ball head 402 is rotated by the anti-slip knob 405 to make the first channel 403 and the second channel 407 coaxial. The energy storage spring 19 can release energy. Under the action of pressure, the piston 15 can automatically squeeze out the coupling agent. When the coupling agent is applied to the human body, the ultrasound probe can be used to perform an ultrasound examination of the fetus. After the squeezing is completed, the ball head 402 is rotated by the anti-slip knob 405 to make the first channel 403 and the second channel 407 misaligned, which can seal the threaded tube 401 and prevent the coupling agent from leaking.

[0035] In cold seasons, to avoid the discomfort caused to patients by the low temperature of the coupling agent, the heating wire 304 inside the placement groove 302 can heat the heat-conducting plate 2 before the coupling agent is extruded. The heat-conducting plate 2 can transfer heat to the coupling agent inside the cylinder 1, thus heating the coupling agent and avoiding discomfort to the human body during the examination.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
