Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an auxiliary device that can reduce magnetic resonance noise. Background Technology

[0002] Magnetic resonance imaging (MRI) is a widely used imaging technique in clinical practice. MRI technology is non-invasive, radiation-free, and provides clear visualization of soft tissues, making it widely used in the medical field and significantly improving diagnostic accuracy for doctors. However, MRI scans produce considerable noise, typically ranging from 60 to 90 decibels, similar to construction site noise or heavy traffic. The noise primarily originates from changes in the machine's magnetic field and the operation of the gradient coils. The examination duration varies, generally between 15 and 30 minutes, during which the noise persists. For most people, this noise is tolerable, but it may be uncomfortable for those sensitive to sound, children, the elderly, and those experiencing anxiety.

[0003] To address the aforementioned issues, the current main approach is to use earplugs or earmuffs for prevention and control. However, earplugs alone have poor sound insulation and cannot effectively block noise. Earmuffs are prone to loosening and tilting during use, and when they move, they lose their original isolation function. In addition, existing earmuffs are difficult to lock and unlock with a single button and lack the ability to switch between sound isolation and non-isolation, which still has some shortcomings.

[0004] Therefore, an auxiliary device that can reduce magnetic resonance noise is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model designs an auxiliary device for reducing magnetic resonance noise, including: an arc-shaped bracket, an external support cover, and an adjustment component; the two ends of the arc-shaped bracket are fixedly connected to the external support cover, the external support cover is a hollow hemispherical structure, and a through hole is opened in the middle of the external support cover, on which the adjustment component is fixedly installed;

[0006] The adjustment assembly includes: a fixed cylinder, a support rod, a rotating head, and an internal connector. The fixed cylinder is fixedly installed on the through hole, and a spring is fixedly installed inside the fixed cylinder. The support rod is sleeved inside the spring, and the rear end of the support rod is fixedly connected to the spring, while the front end extends out of the fixed cylinder. A receiving joint is fixedly installed at the rear end of the support rod, and arc-shaped grooves are symmetrically installed on the side wall of the receiving joint, with grooves formed between the arc-shaped grooves. An internal connector is fixedly installed inside the rotating head, and a side strip is fixedly installed on the outer side wall of the internal connector. The side strip slides on the arc-shaped grooves and grooves. By rotating the rotating head, the sliding change of the internal connector on the arc-shaped grooves and grooves controls the extension and retraction of the support rod.

[0007] Furthermore, the front end of the support rod is detachably connected to an internal fixing assembly, which includes an internal fixing cover and an internal extension rod; a sleeve is fixedly provided at the rear end of the internal fixing cover, the sleeve is detachably installed on the support rod, an internal extension rod is fixedly installed inside the internal fixing cover, and a sealing head is fixedly installed at the front end of the internal extension rod; the end length of the internal extension rod is greater than or equal to the radius of the internal fixing cover.

[0008] Furthermore, the socket can be detachably installed on the support rod by means of threaded connection, insertion connection, or magnetic connection;

[0009] Furthermore, the support rod is made of silicone material, and the sealing head uses materials including silicone, sponge, and rubber;

[0010] Furthermore, a rear support is fixedly installed on one end wall of the arc-shaped support. The rear support has an arc-shaped structure that conforms to the biological anatomical structure of the human body from the back of the head to the neck. The arc-shaped support is telescopically connected by fixing bolts.

[0011] Furthermore, a fixing strap is fixedly provided at the lower end of the external support cover.

[0012] The beneficial effects of this utility model are:

[0013] This utility model discloses an auxiliary device for reducing magnetic resonance imaging (MRI) noise, comprising: an arc-shaped bracket, an external support cover, and an adjustment component; the two ends of the breathing tube are fixedly connected to the external fixation cover, which is a hollow hemispherical structure with a through hole in the middle, on which the adjustment component is fixedly installed; by rotating the rotating head on the adjustment component, the extension and retraction of the internal extension rod can be controlled, thereby moving the sealing head at the front end of the extension rod to block the patient's ear, thus enhancing the noise reduction effect. If the ear is not blocked, the external support cover alone will have a poor blocking effect and a greater impact on noise. Compared with traditional soundproofing devices, this device can achieve one-button blocking and can be adjusted as needed to remind the patient of their position, eliminating the need for frequent removal and wearing.

[0014] In addition, a rear bracket is fixedly installed on one side end wall of the arc-shaped bracket, and a fixing strap is fixedly installed at the lower end of the external support cover. The rear bracket can limit the device in front and behind, and the fixing strap can limit it in the upper and lower directions. By limiting the device in different directions, the problem of poor noise prevention caused by device displacement and sliding during use can be effectively solved. Attached Figure Description

Detailed Implementation

[0025] Example 1

[0026] An auxiliary device for reducing magnetic resonance imaging (MRI) noise includes: an arc-shaped bracket 1, an external support cover 2, and an adjustment component 3. The two ends of the arc-shaped bracket are fixedly connected to the external support cover, which is a hollow hemispherical structure. A through hole 22 is provided in the middle of the external support cover, and the adjustment component 3 is fixedly installed on the through hole 22. By rotating the rotating head 33 on the adjustment component 3, the extension and retraction of the internal extension rod 42 can be controlled, which drives the sealing head 43 at the front end of the extension rod 42 to move, thereby sealing the patient's ear and enhancing the noise reduction effect. If the ear is not sealed, the sealing effect is poor and the noise impact is significant when relying solely on the external support cover 2. Compared with traditional soundproofing devices, this device can achieve one-button sealing and can be adjusted as needed to remind the patient of the correct posture, eliminating the need for frequent removal and wearing.

[0027] Specifically, the adjusting assembly 3 includes: a fixed cylinder 31, a support rod 32, a rotating head 33, and an internal connector 331; the fixed cylinder 31 is fixedly installed on the through hole 22, and a spring is fixedly installed inside the fixed cylinder 31. The support rod 32 is sleeved inside the spring, and the rear end of the support rod 32 is fixedly connected to the spring, while the front end extends out of the fixed cylinder 31; a receiving joint 321 is fixedly installed at the rear end of the support rod 32, and arc-shaped inclined grooves 322 are symmetrically installed on the side wall of the receiving joint 321, with grooves 323 formed between the arc-shaped inclined grooves 322; the internal connector 331 is fixedly installed inside the rotating head 33, and a side strip 332 is fixedly installed on the outer side wall of the internal connector 331, sliding on the arc-shaped inclined grooves 322 and the grooves 323; the internal connector 331 is driven by rotating the rotating head 33. 1. The sliding transformation on the arc-shaped inclined groove 322 and the groove 323 controls the extension and retraction of the support rod 32. The specific working principle is as follows: when the rotating head 33 is rotated, the internal connecting head 331 inside the rotating head 33 will rotate accordingly. Under the rotation of the internal connecting head 331, the side strip plate 332 provided on the internal connecting head 331 will slide along the arc-shaped inclined groove 322. At this time, the support rod 32 moves forward under the action of pressure (the spring is compressed). When the rotating head 33 is rotated again, the internal connecting head 331 inside the rotating head will rotate accordingly. The side strip plate 332 provided on the internal connecting head 331 will slide along the groove 323 until it enters the arc-shaped inclined groove 322. At this time, under the action of the spring force, the bottom end of the arc-shaped inclined groove 322 contacts the side strip plate 332, forming a limiting effect. At this time, the support rod 32 retracts.

[0028] A rear support 11 is fixedly installed on one end wall of the arc-shaped support 1. The rear support 11 has an arc-shaped structure that conforms to the biological anatomical structure of the human body from the back of the head to the neck. The arc-shaped support 1 is also telescopically connected by fixing bolts 12. A fixing strap 21 is fixedly installed at the lower end of the external support cover 2. The rear support 11 can limit the device's movement, providing front-to-back limitation, while the fixing strap 21 provides vertical limitation. By limiting movement in different directions, the problem of device displacement and sliding during use, which leads to poor noise prevention, can be effectively solved. In this embodiment, the presence of the rear support 11 may cause discomfort to the patient's head (when the patient is in a supine position). Therefore, in this embodiment, the rear support 11 can also be made detachable, specifically as follows: Figure 7 As shown, it can be used as a normal headphone. The detachable design can be either threaded or directly plugged in, which is a common design for those skilled in the art and will not be explained further here.

[0029] Example 2

[0030] In this embodiment, based on the adjustment component 3 in embodiment 1, the support rod 32 can be moved back and forth. The front end of the support rod 32 is detachably connected to an internal fixation component 4. The internal fixation component 4 can seal the patient's ear. Specifically, the internal fixation component 4 includes an internal fixation cover 41 and an internal extension rod 42. A sleeve connector 44 is fixedly provided at the rear end of the internal fixation cover 41. The sleeve connector 44 is detachably installed on the support rod 32. The sleeve connector 44 can be detachably installed on the support rod 32 via threaded connection, insertion, or magnetic connection. Because it is detachable, it can be replaced for different patients, ensuring that one patient uses one internal fixation component 4, effectively reducing the probability of cross-infection. Additionally, an internal extension rod 42 is fixedly installed inside the internal fixation cover 41. The front end of the internal extension rod 42... An end-fixed occluder head 43 is fixedly installed. The occluder head 43 further blocks the patient's ear, reducing noise damage. Simultaneously, medical staff can rotate the rotating head 33 as needed to position the occluder head 43 away from the patient's ear, allowing for communication and prompting the patient to change position. In this embodiment, to ensure the occluder head 43 can smoothly contact and block the patient's ear, the end length of the inner extension rod 42 is greater than or equal to the radius of the inner fixing cover 41. The support rod 32 is made of silicone material. The occluder head 43 uses materials including silicone, sponge, and rubber. Utilizing the sealing properties of silicone, a design conforming to the structure of the human ear is created, allowing for use in noisy environments and effectively protecting the eardrum from noise damage. The sponge earplug is soft, comfortable, and smooth, providing good noise reduction and suitable for prolonged wear.
