Description

Technical Field

[0001] This utility model relates to the field of neck feeding and positioning auxiliary components, specifically to a neck auxiliary positioning bracket. Background Technology

[0002] During examinations of patients in the oncology radiotherapy department, clinicians in the radiotherapy department need to use appropriate neck support devices to support the patient's neck and prevent excessive patient movement that could lead to detection errors. However, the existing neck support devices used in oncology radiotherapy have poor applicability, resulting in varying degrees of tightness when restricting neck positioning for different patients. If they are too loose, they will not be able to effectively restrict the patient's neck, while if they are too tight, they may cause negative emotions or physical reactions in the patient, thus significantly affecting the patient's experience. Utility Model Content

[0003] The purpose of this utility model is to provide a neck auxiliary positioning bracket to solve the above-mentioned problems. The base plate is equipped with side limiting members on both sides of the neck pad, and the side limiting members are symmetrically distributed on both sides. Then, by the connecting studs of the side limiting members sliding laterally along the mating groove, the neck side plates on both sides can respectively abut against the two sides of the patient's neck. At the same time, the tightness of the neck side plates in positioning and restricting the patient's neck can be adjusted by turning the limiting nuts. The positioning and restriction operation and the tightness adjustment of the patient's neck are simple and easy to implement, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The present invention provides a neck auxiliary positioning bracket, including a base plate, the base plate being arranged flat, and a neck pad in the shape of an arc plate and arched upward is horizontally mounted on the top surface of the base plate.

[0006] The top surface of the substrate is provided with side limiting members on both sides of the neck pad, and the side limiting members on both sides are symmetrically distributed to position and restrict the patient's neck from both sides.

[0007] Preferably, each of the side limiting components includes a vertical plate, a connecting stud, and a neck side clamp. The vertical plate is vertically fixed along the longitudinal direction on the top surface of the base plate at both sides of the neck pad. The top surface of each vertical plate has a vertically formed mating groove, and the mating groove is a through groove in the transverse direction. The connecting stud is horizontally inserted into each mating groove in a sliding fit manner. The ends of the connecting studs at both sides that are close to each other are fixed to the neck side clamp by connecting sleeves. The neck side clamps at both sides are symmetrically distributed and their bottom contour surfaces are consistent with the top contour surface of the neck pad, so that the neck side clamps at both sides can move laterally along the surface of the neck pad. The connecting studs are coaxially engaged with limiting nuts at the positions corresponding to the neck side clamps and the vertical plate.

[0008] Preferably, each of the mating grooves is provided with a blocking and anti-detachment component at a position higher than the top of the outer periphery of the connecting stud, so as to restrict the connecting stud in the mating groove and prevent it from coming out vertically.

[0009] Preferably, the upper part of the mating groove is a straight groove and the lower part is an arc-shaped groove, and the bottom of the outer periphery of the connecting stud is in close contact with the lower inner periphery of the mating groove.

[0010] Preferably, the neck side plates are all arc-shaped plates and arch towards each other, while the outer surfaces of the neck side plates on both sides that are close to each other are covered with cushioning pads made of cushioning material.

[0011] Preferably, the limiting nuts are all hand-tightened knurled nuts.

[0012] Preferably, the outer ends of the connecting studs on both sides, which are far apart from each other, are fixedly fitted with handles for easy gripping.

[0013] Preferably, each of the blocking and anti-detachment components includes a mating hole, a locking hole, and a locking rod. The front of the upright plate has a mating hole longitudinally at a position higher than the top of the outer periphery of the connecting stud. The mating holes are all through holes and are perpendicularly connected to the corresponding mating grooves. The rear end face of each mating groove has a locking hole longitudinally, and the locking hole is longitudinally coaxial with the mating hole on the same side. The locking rod is inserted into each mating hole longitudinally and coaxially, and the rear end of each locking rod is coaxially mated with the corresponding locking hole. At the same time, the lowest position of the outer periphery of the locking rod is level with the highest position of the outer periphery of the corresponding side connecting stud.

[0014] Preferably, all locking rods are screw rods, and at least one of the mating hole and the locking hole on the same side is a threaded hole that is coaxially threaded with the locking rod.

[0015] Preferably, the front ends of the locking rods are coaxially combined with a gripping end for easy holding and applying force.

[0016] When using the aforementioned neck support bracket for auxiliary positioning of the patient's neck during tumor radiotherapy, an arc-shaped, upward-arching neck pad is horizontally mounted on the top surface of the base plate. This neck pad provides stable support for the patient's neck. Side limiting members are symmetrically distributed on both sides of the neck pad, and the connecting studs of these side limiting members slide laterally along the mating grooves, allowing the neck side clamps to abut against both sides of the patient's neck. The tightness of the neck side clamps can be adjusted by tightening the limiting nuts. The positioning and tightness adjustment methods are simple and easy to implement, adapting to patients of different body sizes and allowing for individual adjustments to the tightness, thus improving usability and comfort, and facilitating better deployment. During the treatment process, since the top of the fitting groove is open, the horizontally placed connecting stud can fall into the fitting groove from the top, allowing it to pass smoothly laterally through the groove. The combination of the connecting stud and the fitting groove is simple and easy to implement. Simultaneously, the fitting groove is equipped with a blocking anti-dislodgement component at a position higher than the top of the connecting stud's outer perimeter. The locking rod of the blocking anti-dislodgement component passes longitudinally through the fitting hole and then coaxially engages with the locking hole, thus restricting the connecting stud within the fitting groove and preventing it from vertically dislodging. Furthermore, the restriction preventing the connecting stud from vertically dislodging within the fitting groove is released once the locking rod sequentially disengages from the locking hole and the fitting hole. The combination and release methods of the connecting stud and the fitting groove are simple and easy to implement. This facilitates the use of the connecting stud in the fitting groove for positioning and restricting the patient's neck, and also facilitates the subsequent removal of the connecting stud from the fitting groove to separate the neck side clamp and the neck pad for easy cleaning and maintenance.

[0017] The beneficial effects are as follows: 1. This utility model has a neck pad with an arc-shaped plate shape and an upward arch on the top surface of the base plate. The neck pad can stably support the patient's neck. At the same time, the base plate is equipped with side limiting members on both sides of the neck pad, and the side limiting members are symmetrically distributed on both sides. The neck side clamps on both sides can be made to abut against the two sides of the patient's neck by sliding the connecting studs of the side limiting members laterally along the mating groove. The tightness of the neck side clamps can also be adjusted by turning the limiting nuts. The positioning and tightness adjustment of the patient's neck are simple and easy to implement. It can not only adapt to the neck positioning and restraint of patients of different body sizes, but also make adaptive adjustments to the tightness of the neck positioning and restraint according to different patients, improving the applicability and comfort of use, and facilitating better implementation of the treatment process.

[0018] 2. With the top of the mating groove open, the horizontally placed connecting stud can easily pass through the mating groove by falling in from the top. The combination of the connecting stud and the mating groove is simple and easy to implement. At the same time, the mating groove is equipped with anti-dislodgement components at a position higher than the top of the connecting stud. The locking rod of the anti-dislodgement component passes through the mating hole longitudinally and engages with the locking hole coaxially, which can restrict the connecting stud in the mating groove and prevent it from coming out vertically. At the same time, the restriction that the connecting stud cannot come out vertically in the mating groove can be released by simply letting the locking rod come out of the locking hole and the mating hole longitudinally. The combination restriction and release method of the connecting stud and the mating groove is simple and easy to implement. It is convenient to restrict the connecting stud in the mating groove for positioning and restricting the patient's neck. It is also convenient to remove the connecting stud from the mating groove and then separate the neck side splint and neck pad for easy cleaning and maintenance. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] See Figures 1-6As shown, this utility model provides a neck auxiliary positioning bracket, including a base plate 2, which is flatly arranged. A neck pad 1 with an arc-shaped plate shape and an upward arch is horizontally mounted on the top surface of the base plate 2. Preferably, the bottom end of the neck pad 1 is fixed to the top surface of the base plate 2 by a flat connecting plate 101. Side limiting members 3 are combined and arranged on both sides of the neck pad 1 on the top surface of the base plate 2, and the side limiting members 3 on both sides are symmetrically distributed to position and restrict the patient's neck from both sides. Specifically, each side limiting member 3 includes a vertical plate 303, a connecting stud 302, and a neck side clamp 307. The vertical plate 303 is vertically fixed on both sides of the neck pad 1 on the top surface of the base plate 2. The top surface of each vertical plate 303 is vertically provided with a mating groove 304, and the mating groove 304 is a through groove in the horizontal direction. The mating groove 304 is horizontally inserted through the connecting stud 302 in a sliding fit, and the connecting studs 302 on both sides are close to each other. The near ends are all fixed with neck side clamps 307 by connecting sleeves 305. The neck side clamps 307 on both sides are symmetrically distributed and the bottom contour surface of both sides is consistent with the top contour surface of the neck pad 1, so that the neck side clamps 307 on both sides can move laterally along the surface of the neck pad 1. The connecting studs 302 are coaxially engaged with the limiting nuts 308 at the positions between the corresponding neck side clamps 307 and the upright plate 303. The advantage of this setting is that, firstly, the neck pad 1 can stably support and place the patient's neck. At the same time, the connecting studs 302 of the side limiting member 3 slide laterally along the mating groove 304 so that the neck side clamps 307 on both sides can respectively abut against the two sides of the patient's neck. Moreover, the tightness of the neck side clamps 307 in positioning and restricting the patient's neck can be adjusted by turning the limiting nuts 308. The positioning and restriction operation and the tightness adjustment of the patient's neck are simple and easy to implement.

[0030] See Figures 1-3As shown, each of the mating grooves 304 is equipped with a blocking and anti-detachment component 4 at a position higher than the top of the outer periphery of the connecting stud 302. This component 4 is used to restrict the connecting stud 302 within the mating groove 304, preventing it from vertically detaching. Specifically, each blocking and anti-detachment component 4 includes a mating hole 403, a locking hole 401, and a locking rod 402. The front of the upright plate 303, at a position higher than the top of the outer periphery of the connecting stud 302, has a mating hole 403 longitudinally formed. These mating holes 403 are all through holes and vertically connected to the corresponding mating groove 304. The rear end face of each mating groove 304 has a locking hole 401 longitudinally formed, and the locking hole 401 is longitudinally coaxially aligned with the mating hole 403 on the same side. Each mating hole 403 has a locking rod inserted longitudinally coaxially. The fixed rod 402 and the rear end of the locking rod 402 are coaxially engaged with the corresponding locking hole 401. At the same time, the lowest position of the outer periphery of the locking rod 402 is level with the highest position of the outer periphery of the corresponding side connecting stud 302. The reason for this setting is that by blocking the locking rod 402 of the anti-loosening component 4 from passing through the mating hole 403 longitudinally and coaxially engaging with the locking hole 401, the connecting stud 302 can be restricted in the mating groove 304 and cannot be dislodged vertically. At the same time, the restriction that the connecting stud 302 cannot be dislodged vertically in the mating groove 304 can be released by simply allowing the locking rod 402 to sequentially dislodge longitudinally from the locking hole 401 and the mating hole 403. The combination restriction and release method of the connecting stud 302 and the mating groove 304 is simple and easy to implement.

[0031] See Figures 1-6As shown, the side limiting member 3 and the blocking and anti-slip member 4 have been optimized as follows. Specifically, for the side limiting member 3, the upper part of the mating groove 304 is a straight groove and the lower part is an arc-shaped groove. At the same time, the outer bottom of the connecting stud 302 is in close contact with the lower inner circumference of the mating groove 304, so that the connecting stud 302 can be well supported by the mating groove 304 and move stably along the mating groove 304 by the outer bottom of the connecting stud 302 being in close contact with the lower inner circumference of the mating groove 304. Optionally, the neck side splints 307 are all arc-shaped plates and arch towards each other. At the same time, the outer surfaces of the neck side splints 307 on both sides are covered and fixed with cushioning pads 306 of cushioning material. With this setting, the outer surface contour of the neck side splints 307 on both sides can more closely fit and restrain the corresponding lateral position of the patient's neck. At the same time, the cushioning pads 306 can directly contact the lateral position of the patient's neck to achieve a good cushioning and comfort effect. Furthermore, all limit nuts 308 are hand-tightened knurled nuts, allowing them to be tightened and loosened directly by hand. The outer ends of the connecting studs 302 on both sides, far apart from each other, are fixedly fitted with handles 301 for easy gripping. This allows the connecting studs 302 to slide laterally along the mating groove 304 by applying force through the handles 301, thereby changing the lateral position of the neck side clamp 307. Specifically, regarding the anti-detachment component 4, the locking rod 402 is a screw rod. At least one of the mating hole 403 and locking hole 401 on the same side is a threaded hole coaxially threaded with the locking rod 402. Preferably, when only one of the mating hole 403 and locking hole 401 on the same side is a threaded hole, the other hole should have a coaxial sliding fit with the locking rod 402. This arrangement facilitates the quick assembly and disassembly of the locking rod 402 with the mating hole 403 and locking hole 401 on the same side by tightening. Optionally, the front end of the locking lever 402 is coaxially combined with a holding end 404 for easy gripping and applying force, so as to use the holding end 404 as the point of force to turn the locking lever 402.

[0032] Using the above structure, specifically for auxiliary positioning of the patient's neck during tumor radiotherapy, a neck pad 1 in the shape of an arc plate and arched upwards is horizontally mounted on the top surface of the base plate 2. The neck pad 1 allows the patient's neck to be stably supported. Simultaneously, side limiting members 3 are symmetrically distributed on both sides of the neck pad 1 on the base plate 2. The connecting studs 302 of the side limiting members 3 slide laterally along the mating grooves 304, allowing the neck side clamps 3 on both sides to be positioned correctly. 07 is positioned against both sides of the patient's neck. The tightness of the neck side splint 307 can be adjusted by turning the limiting nut 308. The positioning and adjustment methods for the patient's neck are simple and easy to implement, adapting to patients of different body sizes and allowing for individual adjustments to the tightness, thus improving usability and comfort. This facilitates better implementation of the treatment process. Furthermore, due to the top of the groove 304... With the part open, the horizontally placed connecting stud 302 can fall into the mating groove 304 from the top, allowing it to pass smoothly laterally through the groove. The combination of the connecting stud 302 and the mating groove 304 is simple and easy to implement. At the same time, the mating groove 304 is equipped with a blocking anti-detachment component 4 at a position higher than the top of the outer periphery of the connecting stud 302. Then, the locking rod 402 of the blocking anti-detachment component 4 passes through the mating hole 403 longitudinally and then engages with the locking hole 401 coaxially, which can restrict the connecting stud 302 in the mating groove 304 and prevent it from moving vertically. The locking rod 402 can be released by sequentially disengaging from the locking hole 401 and the mating hole 403 in the longitudinal direction. This releases the restriction that the connecting stud 302 cannot be disengaged vertically in the mating groove 304. The combination restriction and release method of the connecting stud 302 and the mating groove 304 is simple and easy to implement. It is convenient to restrict the connecting stud 302 in the mating groove 304 for positioning restriction of the patient's neck. It is also convenient to separate the neck side splint 307 and the neck pad 1 after the connecting stud 302 is removed from the mating groove 304 for easy cleaning and maintenance.
