Description

Technical Field

[0001] This invention relates to the field of medical device technology, and specifically to an auxiliary device for breast ultrasound examination. Background Technology

[0002] Ultrasound diagnosis involves an ultrasound diagnostic instrument emitting ultrasound waves into human tissues and using the sonographic data formed by the echoes produced by the tissues to detect and diagnose diseases. It is widely used in the field of medical diagnosis due to its painless, non-invasive, intuitive, and convenient characteristics. Currently, for ultrasound examinations of women's breasts, patients need to cooperate by fully exposing their breasts.

[0003] Chinese Patent No. CN110680389B discloses a breast fixation device for medical ultrasound examination, relating to the field of medical ultrasound examination auxiliary instruments. It includes a silicone anti-slip pad, a nursing body, an operating notch, a through hole, a rotating groove, rotating balls, a support rod, a fixing cylinder, a boss, a fixing frame, a cover plate, screw holes, and reinforcing ribs. The beneficial effects of this invention are: it is specifically designed to fix the patient's breast and protect privacy during cardiac ultrasound examinations. The design is simple, effectively fixing and maintaining the breast's position, facilitating examination from multiple angles for the ultrasound physician, and reducing the impact of breast obstruction on the examination area. Furthermore, this device can significantly reduce patients' embarrassment during ultrasound examinations of the surrounding breast areas, alleviating their psychological burden, relaxing them, improving examination comfort, and enhancing the efficiency and accuracy of ultrasound examinations.

[0004] While the breast fixation device in the aforementioned patent achieves breast position fixation and breast concealment, it is difficult to completely conceal the breast. Furthermore, the components that conceal the breast are connected via an external support rod, requiring the patient to adjust the concealing components in real time during the doctor's examination. This is not only cumbersome but also makes it difficult to quickly achieve multi-angle ultrasound examination. Moreover, the concealing components cannot achieve true fixation to the chest; changes in patient position or excessive touching by the doctor during examination can cause the concealing components to shift. Summary of the Invention

[0005] The purpose of this invention is to address the problems of conventional breast ultrasound examination auxiliary devices, which cannot achieve rapid multi-angle ultrasound exploration while fully protecting privacy, and have low reliability in privacy protection and examination stability. This invention provides an auxiliary device for breast ultrasound examination.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] An auxiliary device for breast ultrasound examination includes a contact ring, a circular cover rotatably mounted on top of the contact ring, a groove formed on the circular cover, a slider slidably mounted in the groove, a rubber ring fixed in the middle of the slider, a telescopic layer fixed between the slider and the groove, an air pump fixed to the side wall of the contact ring, a torque tube rotatably connected to the top of the air pump, a tie fixed between the torque tubes, and a positioning assembly movably mounted in the cavity of the contact ring. The positioning assembly includes a pressurizing chamber, multiple T-shaped elastic pistons movably connected to the bottom of the pressurizing chamber, a rubber cover fixed to the bottom of the T-shaped elastic pistons, wedge-shaped stepped blocks slidably inserted into both sides of the middle of the T-shaped elastic pistons, an elastic piston column slidably connected to the top of the pressurizing chamber, and a locking rod slidably connected to the top of the air pump.

[0008] Furthermore, the rubber ring is rectangular in shape to fit the ultrasonic probe, and the inner wall of the rubber ring includes multiple soft hairs.

[0009] Furthermore, the T-shaped elastic piston is hollow, and the elastic piston rod is slidably inserted into the middle of the T-shaped elastic piston.

[0010] Furthermore, the bottom of the wedge-shaped step block includes a wedge groove, and a support rod that is fixedly connected to the rubber cover is movably engaged in the wedge groove. The support rod is slidably connected to the outer wall of the T-shaped elastic piston.

[0011] Furthermore, the positioning assembly also includes a guide ring rotatably installed in the top wall cavity of the contact ring, a plurality of inclined grooves opened at the bottom of the guide ring, an arc groove opened at the top of the guide ring, and a pin fixedly provided on the lever that is movably connected to the arc groove.

[0012] Furthermore, the top of the elastic piston rod moves and abuts in the inclined groove, and the elastic force of the elastic piston rod is greater than the elastic force of the T-shaped elastic piston.

[0013] Furthermore, the bottom of the pressurization chamber is provided with a live groove that is sealed and connected to the T-shaped elastic piston.

[0014] Furthermore, the clamping rod includes a clamping portion that penetrates the torque tube.

[0015] Furthermore, the output end of the air pump is connected to the pressurization chamber.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention utilizes the winding effect of a torsion tube on the straps to control the two contact rings to be bundled together for easy storage. During use, the patient can freely control the stretching of the straps by grasping the two round covers on both sides according to the distance between the chests, so that the round covers and contact rings are attached to the outside of the chest, thereby completely covering the chest and protecting privacy. During the test, after the probe is inserted into the rubber ring, the probe is fixed by the movement of the slider and the reverse of the rubber ring, and its multi-directional deflection property allows the doctor to perform multi-angle detection and examination of the patient's chest.

[0018] 2. In this invention, after the contact ring is placed on the outside of the chest, air is continuously supplied to the pressurization chamber. Each T-shaped elastic piston automatically moves down under air pressure, driving the rubber cover to achieve multi-point adsorption connection. Since there are multiple rubber covers, each located in a different direction on the outside of the chest, the split adsorption connection is convenient to cope with different flatness of the outside of the chest. Utilizing the difference in elasticity between the T-shaped elastic piston and the elastic piston column, the T-shaped elastic piston and the elastic piston column move sequentially. Therefore, a low negative pressure is automatically formed inside the rubber cover in the early stage of complete adsorption, and then a high negative pressure is formed for reinforcement. At the same time, the clamping rod applies pressure to the inner wall of the torsion tube to eliminate the influence of the tension between the straps on the torsion tube on the positioning of the contact ring, thereby improving the reliability of the device for privacy protection and the stability of auxiliary examination.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 1-8 As shown, an auxiliary device for breast ultrasound examination includes a contact ring 1, a circular cover 2 rotatably mounted on the top of the contact ring 1, a groove 3 opened on the circular cover 2, a slider 4 slidably mounted in the groove 3, a rubber ring 5 fixed in the middle of the slider 4, a telescopic layer 6 fixed between the slider 4 and the groove 3, an air pump 7 fixed to the side wall of the contact ring 1, a torque tube 8 rotatably connected to the top of the air pump 7, a tie 81 fixed between the torque tubes 8, and a positioning assembly 9 movably mounted in the wall cavity of the contact ring 1. The positioning assembly 9 includes a pressurizing chamber 91, multiple T-shaped elastic pistons 92 movably connected to the bottom of the pressurizing chamber 91, a rubber cover 93 fixed to the bottom of the T-shaped elastic pistons 92, wedge groove step blocks 94 slidably inserted into both sides of the middle of the T-shaped elastic pistons 92, an elastic piston column 96 slidably connected to the top of the pressurizing chamber 91, and a locking rod 910 slidably connected to the top of the air pump 7.

[0030] More specifically, when using the device, the patient, based on the distance between their chests, freely controls the stretching of the straps 81 on both sides of the circular cover 2. After the circular cover 2, along with the contact ring 1, is placed around the chest, the doctor uses the air pump 7 to control the rapid and continuous supply of air into the pressurization chamber 91. Each T-shaped elastic piston 92 automatically moves downwards under air pressure, causing the rubber cover 93 to achieve multi-point suction connection. Since there are multiple rubber covers 93, each located in a different direction on the outside of the chest, this modular suction connection is convenient for handling varying degrees of flatness on the chest. While the rubber cover 93 is pressing against the skin and expelling internal air, the elastic piston column 96 continuously moves upwards relative to the T-shaped elastic piston 92. Therefore, a low negative pressure automatically forms inside the rubber cover 93 before complete suction. During this period, the rubber cover 93 deforms under pressure, causing the support rod 95 to move upwards, and the wedge-shaped stepped block 94 moves outwards under pressure to abut against the inner wall of the movable groove, thereby fixing the T-shaped elastic piston 92. Subsequently, as the pressurization chamber 91 continues to increase pressure, the elastic piston column... Based on its greater elasticity than the T-shaped elastic piston 92, 96 moves further upward relative to the T-shaped elastic piston 92 to increase the negative pressure of the rubber cover 93, thereby adsorbing and reinforcing it to ensure the firmness of the contact ring 1 connection. At the same time, the inclined groove 98 at the bottom of the guide ring 97 is squeezed by the elastic piston column 96, causing the guide ring 97 to deflect. Using the arc groove 99, the guide ring 97 then pulls the pin 911, causing the clamp 910 to apply pressure to the inner wall of the torque tube 8 to eliminate the influence of the tension between the straps 81 on the torque tube 8 on the positioning of the contact ring 1, thereby improving the reliability of the device for privacy protection and the stability of auxiliary examination. After the contact ring 1 is completely fixed to the periphery of the chest, the doctor controls the ultrasound probe to extend into the rubber ring 5. By using the slider 4 to move and the rubber ring 5 to fix the probe in the opposite direction and allow it to deflect in multiple directions, the doctor can perform multi-angle detection and examination of the patient's chest. The round cover 2, slider 4 and telescopic layer 6 can completely cover the chest to protect privacy.

[0031] like Figure 1 and Figure 5 As shown, in some embodiments, the rubber ring 5 is rectangular and adapted to the ultrasound probe, and the inner wall of the rubber ring 5 includes multiple soft hairs. Specifically, the round cover 2, the slider 4 and the rubber ring 5 can provide privacy protection for the chest, and the rubber ring 5 used for inserting the ultrasound probe, combined with the soft hairs, further enhances the comprehensiveness of the protection.

[0032] like Figure 4As shown, in some embodiments, the T-shaped elastic piston 92 is hollow, and the elastic piston column 96 is slidably inserted into the middle of the T-shaped elastic piston 92. Specifically, during the period when the rubber cover 93 is pressed against the skin and squeezes out the internal air, the elastic piston column 96 continuously moves upward relative to the T-shaped elastic piston 92. Therefore, a low negative pressure will automatically form inside the rubber cover 93 before complete adsorption. Subsequently, after the rubber cover 93 is fixed, the elastic piston column 96 moves further upward relative to the T-shaped elastic piston 92, thereby increasing the negative pressure of the rubber cover 93, adsorbing and reinforcing it, and ensuring the firmness of the connection of the contact ring 1.

[0033] like Figure 4 As shown, in some embodiments, the bottom of the wedge groove step block 94 includes a wedge groove, and a support rod 95 fixedly connected to the rubber cover 93 is movably engaged in the wedge groove. The support rod 95 is slidably connected to the outer wall of the T-shaped elastic piston 92. Specifically, when the rubber cover 93 adsorbs the skin, it deforms under pressure, causing the support rod 95 to move upward. The wedge groove step block 94 moves outward under pressure and abuts against the inner wall of the movable groove, thereby driving the T-shaped elastic piston 92 to be fixed, so that the elastic piston column 96 can be moved relative to the T-shaped elastic piston 92 to create a deep negative pressure on the rubber cover 93.

[0034] like Figure 2-6 As shown, in some embodiments, the positioning component 9 further includes a guide ring 97 rotatably installed in the top wall cavity of the contact ring 1, a plurality of inclined grooves 98 opened at the bottom of the guide ring 97, an arc groove 99 opened at the top of the guide ring 97, a pin 911 fixed on the locking rod 910 and movably connected to the arc groove 99, the top of the elastic piston 96 movably abutting in the inclined groove 98, and the locking rod 910 includes a locking part through which the torque tube 8 passes. Specifically, while the rubber cover 93 is deeply adsorbed by air pressure, the inclined groove 98 is squeezed by the elastic piston 96, which guides the guide ring 97 to deflect. Using the arc groove 99, the guide ring 97 then pulls the pin 911, so that the locking rod 910 applies pressure to the inner wall of the torque tube 8 to eliminate the influence of the tension between the straps 81 on the positioning of the contact ring 1.

[0035] like Figure 4 As shown, in some embodiments, the elastic force of the elastic piston column 96 is greater than that of the T-shaped elastic piston 92. Specifically, when the pressure chamber 91 is continuously pressurized, the T-shaped elastic piston 92 preferentially drives the rubber cover 93 to adhere to the skin. After low-pressure adsorption and fixation, based on the property that the elastic force of the elastic piston column 96 is greater than that of the T-shaped elastic piston 92, the pressure chamber 91 continues to pressurize. The T-shaped elastic piston 92 cannot be pressed down, and the elastic piston column 96 is pressed and then moves further up relative to the T-shaped elastic piston 92 to increase the negative pressure of the rubber cover 93, adsorb and reinforce it, and ensure the firmness of the connection of the contact ring 1.

[0036] like Figure 4As shown, in some embodiments, the bottom of the pressurization chamber 91 is provided with a live groove that is sealed and connected to the T-shaped elastic piston 92.

[0037] like Figure 1 and Figure 7-8 As shown, in some embodiments, the output of the air pump 7 is connected to the pressurization chamber 91.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
