The embodiment of the application discloses an adjustable neck brace.

Referring to fig. 1 and 2, an adjustable neck brace includes a neck brace 1, a plurality of pressure sensors 2, a plurality of sets of flexible bladders 3, an air supply 4, and a control module 5.

Referring to fig. 1 and 2, the neck bracket 1 is hollowed out to form a window to expose the neck portion. The neck bracket 1 comprises an upper bracket 11 and a lower bracket 12, with a window located between the upper bracket 11 and the lower bracket 12. In this embodiment, the neck bracket 1 is provided with windows both in front and back and side edges are not provided. In other embodiments, a window may be provided on the side.

In which, referring to fig. 2, the outer peripheral sides of the upper and lower brackets 11 and 12 are provided with the height adjuster 6. The height adjusting member 6 can effectively adjust the distance between the upper and lower brackets 11 and 12, thereby adjusting the overall height of the neck bracket 1 to fit the neck heights of different patients. The height adjusting member 6 is a structure of the prior art, which is not described in detail, and can adjust the distance between the upper bracket 11 and the lower bracket 12.

Referring to fig. 2, a plurality of pressure sensors 2 are installed at both upper and lower sides of the neck bracket 1, and when a patient uses, the upper end of the upper bracket 11 contacts with the head of the patient, and the lower end of the lower bracket 12 contacts with the shoulder of the patient, the pressure sensors 2 can effectively monitor the feedback pressure data value, thereby facilitating a doctor to judge the neck recovery condition of the patient according to the pressure data later, or adaptively adjust the treatment scheme of the patient according to the pressure data. In the present embodiment, the pressure sensors 2 are provided in eight, the upper brackets 11 are provided in four, and the lower brackets 12 are provided in four.

Referring to fig. 2 and 3, a plurality of groups of elastic air bags 3 are arranged around the periphery of the neck bracket 1 and positioned at the window, a plurality of groups of vent valves 7 (see fig. 4 in detail) are arranged on one side of the elastic air bags 3 close to the inside of the neck bracket 1, and the vent valves 7 can be electromagnetic valves. In the present embodiment, the elastic air bags 3 are provided with three groups, and the three groups of elastic air bags 3 communicate with each other. The air supply piece 4 is located the outside of neck bracket 1 and is used for inflating elasticity gasbag 3, and air pump can be selected for use to air supply piece 4, and air supply piece 4 can be connected with the gas flowmeter for monitor the volume of inflating. The control module 5 is electrically connected with the air supply valve 7 and the air supply piece 4, respectively, and the control module 5 is connected with a plurality of control buttons, which are used for adjusting the working modes of the air supply piece 4 and the air supply valve 7.

When the external temperature is moderate, the control module 5 controls the air supply member 4 to supply the first inflation amount of air to the elastic air bags 3, and when the elastic air bags 3 are in the partially inflated state (as shown in fig. 3), the adjacent elastic air bags 3 are spaced apart. Thus the window is not completely covered, and the neck brace has certain ventilation to improve the comfort of the neck brace.

When the external temperature is low, the control module 5 controls the air supply member 4 to supply the air of the second inflation amount to the elastic air bag 3, the second inflation amount is larger than the first inflation amount, at this time, the elastic air bag 3 is in an inflated state (it can be understood that the elastic air bag 3 in fig. 3 can be inflated at the upper side and the lower side), and the adjacent elastic air bags 3 are abutted against each other and cover the window. Therefore, the external cold air can be effectively reduced from entering the neck support, so that the neck of a patient is relatively cold, and the warmth retention property of the neck support is enhanced.

When the external temperature is high, the control module 5 controls the vent valve 7 to be alternately closed and opened, and simultaneously controls the air supply member 4 to be intermittently activated so that the elastic air bag 3 is alternately inflated and deflated toward the inside of the neck bracket 1. Specifically, the vent valve 7 is closed first, and the air supply member 4 is activated to inflate the elastic air bag 3. When the inflation amount reaches the set standard, the air supply piece 4 is closed at the moment, and the ventilation valve 7 is opened, so that air is discharged from the ventilation valve 7 to be blown to the neck of the patient, thereby enhancing the ventilation effect and realizing a certain cooling effect.

Specifically, referring to fig. 2, a mounting frame 8 is provided at the window, and the mounting frame 8 is attached to the window side wall between the upper bracket 11 and the lower bracket 12. The mounting frame 8 includes a cross frame 81 and a vertical frame 82 connected to each other. In this embodiment, two cross frames 81 and two vertical frames 82 are respectively arranged, one is arranged on top of the other, the other is arranged on the left and right of the other, and the cross frames 81 and the vertical frames 82 are connected end to form a square frame.

Referring to fig. 2 and 3, a plurality of first limiting plates 9 made of hard materials are arranged on one side of the mounting frame 8 close to the neck, a second limiting plate 10 made of hard materials is arranged on one side of the mounting frame 8 away from the neck, and the elastic air bag 3 is located between the first limiting plates 9 and the second limiting plates 10. The number and the size of the first limiting plate 9, the second limiting plate 10 and the elastic air bags 3 are adaptively set according to the size of the window.

In this embodiment, two ends of each first limiting plate 9 are fixedly connected with the vertical frame 82 of the mounting frame 8. In other embodiments, the first limiting plate 9 may be mounted vertically. The elastic air bag 3 is located at one side of the first limiting plate 9 away from the neck, the first limiting plate 9 is arranged at intervals with the neck, the first limiting plate 9 is provided with a vent hole 91 (see fig. 4 in detail) communicated with the elastic air bag 3, and the vent valve 7 is located at the vent hole 91 to control the opening and closing of the vent hole 91.

When the elastic air bag 3 deforms, the first limiting plate 9 cannot deform because the first limiting plate 9 is hard. The elastic air bag 3 can only be abutted to the first limiting plate 9 in expansion deformation, so that the neck of a patient cannot be abutted, and the occurrence of the condition that the blood circulation of the neck of the patient is possibly unsmooth is reduced. Meanwhile, the first limiting plate 9 can improve the attachment point for the installation of the elastic air bag 3, so that shaking possibly generated when the elastic air bag 3 is inflated and deflated is reduced, and secondary injury possibly caused to the neck of a patient by shaking is further reduced.

Wherein, referring to fig. 3 and 4, the vent hole 91 includes a first vent hole 911 and a second vent hole 912 that are communicated with each other, the first vent hole 911 has a larger aperture than the second vent hole 912, the first vent hole 911 is located at a side of the first limiting plate 9 near the elastic airbag 3, the second vent hole 912 is located at a side of the first limiting plate 9 far from the elastic airbag 3, and the vent valve 7 is located at the first vent hole 911 to control the opening and closing of the first vent hole 911.

When high pressure air is ejected through the vent hole 91, the velocity of the air increases rapidly with a concomitant decrease in pressure. According to the law of conservation of energy, the kinetic energy of the air is increased and the temperature is reduced. Therefore, when air having a certain pressure is ejected from the elastic bag 3 through the first vent hole 911 and the second vent hole 912, the temperature of the air can be reduced to a certain level at this time. When the neck brace is used under the condition of higher external temperature, the air flows out from the vent hole 91, so that the circulation of external air and air at the neck can be quickened, the cooled air can be blown to the neck, and the comfort level of the neck brace is improved.

In addition, in the present embodiment, the second vent hole 912 is provided in a horn shape, and the opening of the horn is directed away from the elastic air bag 3.

Firstly, the horn shape can effectively disperse the air flow in the elastic air bag 3 to different directions, so as to avoid the impact on the same position of the neck as much as possible, thereby enlarging the contact surface area of the air flow and the neck and improving the ventilation effect in a high-temperature environment. Secondly, loudspeaker form can play the slow flow effect, reduces air velocity, avoids causing great impact force to the neck, consequently can effectively improve the comfort level when wearing the neck brace.

In this embodiment, in order to reduce noise that may be generated when the gas is discharged from the vent hole 91, the wall of the vent hole 91 is coated with a sound absorbing material. The sound absorbing material can effectively reduce noise, and further improves the comfort level of the patient. The sound absorbing material may be acoustic paint, polymer paint, or the like to reduce noise.

Referring to fig. 3 and 4, the first limiting plate 9 includes a heat conducting layer 92 and a heat insulating layer 93 fixedly connected, the heat conducting layer 92 is close to the elastic air bag 3, the heat conducting layer 92 is used for exchanging heat with the gas in the elastic air bag 3, and the heat insulating layer 93 is far away from the elastic air bag 3. The thermally conductive layer 92 includes a thermally conductive shell and a phase change material located inside the thermally conductive shell that is capable of phase changing to absorb heat when the temperature increases.

For example, the phase change material may be a polymer phase change material that changes phase at about 30 degrees celsius, and during the phase change, the polymer phase change material changes from a solid state to a liquid state to absorb heat. When the neck brace is used in a high-temperature environment, the phase-change material absorbs heat and liquefies at the moment, so that the temperature of the gas in the elastic air bag 3 can be effectively reduced, the temperature of the gas blown out of the vent hole 91 is further reduced, and cold air is blown to the neck of a patient to improve the comfort level of the patient.

When the neck brace is used in a low-temperature environment, the temperature of the gas in the elastic air bag 3 is correspondingly low, so that the heat insulation layer 93 can effectively prevent the heat transfer between the low-temperature air and the neck, and the heat insulation property of the neck brace in the low-temperature environment is enhanced. The insulating layer 93 may be made of mineral wool or other materials to further reduce heat transfer.

Referring to fig. 2 and 4, two ends of the second limiting plate 10 are also fixedly connected with the vertical frame 82 of the mounting frame 8, and the second limiting plate 10 may be made of hard plastic. When the air supply piece 4 inflates the elastic air bag 3, the first limiting plate 9, the second limiting plate 10 and the upper and lower transverse frames 81 can effectively limit the deformation direction of the elastic air bag 3.

When the neck brace is used in a low-temperature environment, due to the limiting effect of the first limiting plate 9 and the second limiting plate 10, the elastic air bags 3 can be rapidly expanded towards the upper side and the lower side, so that the two adjacent elastic air bags 3 can be rapidly abutted to close a window, and the warmth retention property of the neck brace used in the low-temperature environment is enhanced. Simultaneously, the cooperation of the second limiting plate 10 of stereoplasm and the first limiting plate 9 of stereoplasm makes the elastic air bag 3 expand more stable when deformation, is difficult for rocking, therefore can reduce as far as possible and rock the injury that probably causes patient's neck.

Referring to fig. 2, the upper cross frame 81 is fixedly connected to the upper bracket 11, and the lower cross frame 81 is fixedly connected to the lower bracket 12. The vertical frame 82 between each two first limiting plates 9 is provided with a stretching member 13, the stretching member 13 being adapted to deform to accommodate the height adjustment of the upper and lower brackets 11, 12.

Specifically, referring to fig. 2 and 5, the stretching member 13 includes two links 131, the centers of the two links 131 being hinged to form a scissors structure, and both ends of the links 131 being hinged to the vertical frame 82.

When the height between the upper bracket 11 and the lower bracket 12 is adjusted by the height adjusting member 6, at this time, the upper bracket 11 drives the cross frame 81 of the installation frame 8 to move, and the cross frame 81 moves to drive the vertical frame 82 to move, so as to drive the first limiting plate 9 and the second limiting plate 10 to move synchronously, and at this time, the connecting rod 131 correspondingly rotates to enable the space between the elastic air bags 3 to change uniformly.

The implementation principle of the embodiment is as follows:

when the external temperature is low, the control module 5 controls the air supply piece 4 to be inflated, so that the elastic air bag 3 is inflated to expand and close the window, and the heat insulation performance of the neck support is improved.

When the external temperature is moderate, the control module 5 controls the air supply piece 4 to be inflated, so that the air permeability of the neck brace can be increased by separating the elastic air bags 3.

When the external temperature is high, the control module 5 controls the air supply 4 to intermittently start and controls the closing and opening of the vent valve 7. The air supply member 4 is opened first, and the vent valve 7 is closed, so that the elastic air bag 3 is inflated. The gas supply 4 is then closed and the vent valve 7 is opened so that gas flows out of the vent hole 91 and blows towards the patient's neck. The ventilation and temperature reduction can be accelerated and the comfort level of the patient can be improved by circularly repeating the steps.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
