Description

Technical Field

[0001] This utility model belongs to the field of fixed pillow technology, specifically relating to a head-fixing pillow. Background Technology

[0002] During local anesthesia in adults, the pain from muscle traction and the patient's fear of surgery can cause significant head displacement. Furthermore, when performing muscle surgeries in different locations, patients often need to move their eyes, which can also lead to unnecessary head movements. Children undergoing surgery are typically under general anesthesia, but this method lacks proper head fixation after anesthesia, and some patients may experience changes in head and eye position during surgery due to variations in the depth of anesthesia. Therefore, currently, there is a lack of head fixation devices suitable for the head circumference of both adults and children after anesthesia. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a head fixation pillow. The adjustable size of the first fixing parts on both sides can adapt to the head size of different patients and provide personalized fixation. The flexible material constituting the air bladder or water bladder can disperse pressure and improve comfort. At the same time, the support strength can be adjusted by filling with liquid or air.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A head-fixing pillow includes a second fixing part, with first fixing parts fixed on both sides of the second fixing part. The size of the first fixing part along the direction of the two first fixing parts can be adjusted according to the head size. The first fixing part is either an air bladder or a water bladder.

[0006] By adopting the above technical solution, the adjustable size of the first fixation part on both sides can adapt to the head size of different patients and provide personalized fixation. The flexible material that constitutes the air bag or water bag can disperse pressure and improve comfort. At the same time, the support strength can be adjusted by filling with liquid or air.

[0007] Preferably, both first fixing parts are airbags, and a first air valve is provided on the first fixing part. The two first fixing parts are respectively arranged from left to right along the second fixing part.

[0008] By adopting the above technical solution and using a uniform airbag, the structure of the airbag can be simplified, and the size can be adjusted quickly by inflating and deflating the airbag through the air valve. The first fixing part set on the left and right conforms to the symmetry of the human head, which facilitates the strengthening of fixation stability on both sides of the patient's head.

[0009] Preferably, both first fixing parts are cylindrical, and a first crease is provided along the axial direction of the top of each of the two first fixing parts. The first crease is provided from front to back along the second fixing part. Each of the two first fixing parts is provided with a fixing strap. When the first fixing part is folded along the first crease, the fixing strap detachably fixes the two sides of the crease of the first fixing part to each other. The fixing strap is provided along the circumference of the first fixing part.

[0010] Using the above technical solution, the cylindrical structure can conform to the curve of the side of the head. The first crease is set along the axis to guide the folding and deformation of the airbag, thereby improving the adaptability to different head circumferences of patients. In the initial state, i.e. the folded state, the first fixing part is folded along the first crease. The fixing strap fixes the two opposite contact surfaces of the first fixing part. Inflation is used to expand the circumference diameter of the first fixing part. When the inflation reaches the point where the fixing strap needs to be removed, the fixing strap is untied, so that the first fixing part continues to expand to both sides, thereby adapting to patients with smaller head circumferences.

[0011] Preferably, each of the two ends of the first fixing part is provided with a third crease radially, one end of the third crease intersects with the first crease and the third crease is perpendicular to the horizontal plane.

[0012] Using the above technical solution, the third crease is perpendicular to the horizontal plane, so that the airbag naturally unfolds to both sides when it is compressed, increasing the contact area and reducing local pressure. The crease intersects with the first crease to form a folding fulcrum, which enhances the controllability of the folding structure.

[0013] Preferably, the first fixing part is further provided with second creases on both sides, the second creases are symmetrically arranged on both sides of the corresponding third crease, and the ends of the second crease and the third crease on the same side intersect at a point.

[0014] Using the above technical solution, the symmetrical second and third folds intersect to form a multi-directional folding network, making the airbag more adaptable to the shape of the head and avoiding uneven support caused by single-point folding of the airbag.

[0015] Preferably, a strap is detachably provided between the two first fixing parts.

[0016] Using the above technical solution, the detachable strap provides additional fixing force, and during use, it generates pressure from above to adaptively squeeze the head, further preventing the head from shifting to the side. It is suitable for scenarios involving vigorous activities, and the detachable design makes it easy to clean or replace.

[0017] Preferably, each of the two first fixing parts is provided with a fixing rod, and the two ends of the fixing rod are respectively hinged to the first fixing part; the two ends of the strap pass through the fixing rod on the corresponding side and are flipped and pasted onto the body. Each end of the strap is provided with a corresponding first hook and loop fastener, which includes a first hook and loop female fastener and a first hook and loop female fastener. When the strap is flipped, the first hook and loop female fastener and the first hook and loop female fastener are attached.

[0018] Using the above technical solution, the hinged fixing rod allows for adjustment of the strap angle, which can adapt to different head circumferences and wearing angles. The Velcro flip-up design facilitates quick wear and the length is adjustable.

[0019] Preferably, the second fixing part is an airbag, and a second air valve is provided on the second fixing part.

[0020] Using the above technical solution, the second fixing part adopts an airbag, which forms a linkage adjustment with the first fixing parts on both sides to improve the overall adaptability. The air valve structure with independent air valves on the first fixing part and the second fixing part can realize the hardness graded control of the first fixing part and the second fixing part.

[0021] Preferably, a fourth crease is provided along the transverse central axis of the second fixing part, and in the deflated state, the second fixing part can be recessed along the transverse central axis; the fourth crease is connected to the third fixing part through a connector.

[0022] Using the above technical solution, the connector enables flexible expansion of the neck support module, and the fourth crease allows the second fixing part to be recessed, which facilitates the storage of the third fixing part of the subsequent expansion module.

[0023] Preferably, the connector includes two connecting straps, one end of which is fixed to the fourth crease on the second fixing part, and the other end of which is fixed to the corresponding side of the third fixing part. Both connecting straps are provided with a length adjustment structure.

[0024] Using the above technical solution, the length adjustment structure can precisely adjust the distance between the third fixation part of the neck support and the second fixation part, adapting to the physiological curvature and body shape requirements of different patients.

[0025] Furthermore, the length adjustment structure adopts either an adjustment buckle or a third type of Velcro.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0027] The adjustable size of the first fixation part on both sides can adapt to different patients' head sizes and provide personalized fixation. The flexible material that makes up the air or water bladder can disperse pressure and improve comfort. At the same time, the support strength can be adjusted by filling with liquid or air.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] The following is combined with Figures 1-3 This utility model will be described in detail.

[0036] Example 1

[0037] A head-supporting pillow, see attached. Figure 1It includes a second fixing part 8, on both sides of the second fixing part 8, a first fixing part 1, the size of the first fixing part 1 along the setting direction of the two first fixing parts 1 can be adjusted according to the head size; the first fixing part 1 adopts either an air bag or a water bag; through the adjustable size of the first fixing parts 1 on both sides, it can adapt to the head size of different patients and provide personalized fixation. The flexible material constituting the air bag or water bag can disperse pressure and improve comfort. At the same time, the support strength can be adjusted by filling with liquid or air.

[0038] In this embodiment, both first fixing parts 1 are airbags, and each first fixing part 1 is provided with a first air valve 17. The two first fixing parts 1 are respectively arranged from left to right along the second fixing part 8. The use of airbags simplifies the structure of the airbag and facilitates quick inflation and deflation of the air valve to adjust the size. The first fixing parts 1 arranged on the left and right conform to the symmetry of the human head, which facilitates enhanced fixation stability on both sides of the patient's head.

[0039] In this embodiment, both first fixing parts 1 are cylindrical, and a first fold 2 is provided along the axial direction of the top of each of the two first fixing parts 1. The first fold 2 is provided along the second fixing part 8 from front to back. Each of the two first fixing parts 1 is provided with a fixing strap 14. When the first fixing part 1 is folded along the first fold 2, the fixing strap 14 detachably fixes the two sides of the fold of the first fixing part 1 to each other. The fixing strap 14 is provided along the circumference of the first fixing part 1. The cylindrical structure can conform to the curve of the side of the head. The first fold 2 is provided along the axial direction to guide the folding deformation of the airbag, thereby improving the adaptability to different head circumferences of patients. In the initial state, i.e., the folded state, the first fixing part 1 is folded along the first fold 2. The fixing strap 14 fixes the two opposite contact surfaces of the folded first fixing part 1. Inflation is used to expand the circumference diameter of the first fixing part 1. When the airbag needs to be disassembled, the fixing strap 14 is untied, so that the first fixing part 1 continues to expand to both sides, thereby adapting to patients with smaller head circumferences.

[0040] The cylinder is the shape of the first fixing part 1 after it is inflated, and the narrowest distance between the two adjacent sides of the two cylinders is 120mm; the diameter of the two cylinders when fully inflated is 80mm.

[0041] One end of the fixing strap 14 is fixed to the surface of the fixing part 1, and the other end of the fixing strap 14 is fixed to the fixing part 1 via a second hook and loop fastener 15 relative to one side of the fixing part 1. The second hook and loop fastener 15 includes a second hook and loop female fastener. The second hook and loop female fastener is disposed on the fixing strap 14, and the corresponding second hook and loop female fastener is disposed on the fixing part 1.

[0042] In this embodiment, each of the two ends of the first fixing part 1 is radially provided with a third crease 4. One end of the third crease 4 intersects with the first crease 2 and the third crease 4 is perpendicular to the horizontal plane. The third crease 4 is perpendicular to the horizontal plane, so that the airbag naturally unfolds to both sides when it is compressed, thereby increasing the contact area and reducing the local pressure. The crease intersects with the first crease 2 to form a folding fulcrum, thereby enhancing the controllability of the folding structure.

[0043] The length of the third crease 4 is 60mm.

[0044] In this embodiment, refer to the appendix. Figure 3 The first fixing part 1 is also provided with second folds 3 on both sides. The second folds 3 are symmetrically arranged on both sides of the corresponding third fold 4, and the ends of the second folds 3 and the third fold 4 on the same side intersect at a point. The symmetrical second folds 3 and the third fold 4 intersect to form a multi-directional folding network, which makes the airbag more adaptable to the shape of the head and avoids uneven support force caused by single-point folding of the airbag.

[0045] Example 2

[0046] Unlike Embodiment 1, in this embodiment, a strap 6 is detachably provided between the two first fixing parts 1; the detachable strap 6 provides additional fixing force, and when in use, it generates pressure from above to adaptively squeeze the head, further preventing the head from shifting to the side, making it suitable for intense activity scenarios, and the detachable design facilitates cleaning or replacement.

[0047] Among them, the strap 6 is made of elastic material made of elastic fabric.

[0048] In this embodiment, two first fixing parts 1 are provided with fixing rods 5. The two ends of the fixing rods 5 are respectively hinged to the first fixing parts 1. Since it is a hinged connection structure, the two ends of the fixing rods 5 can rotate relative to the surface of the first fixing parts to adjust the angle. The two ends of the strap 6 pass through the fixing rods 5 on the corresponding sides and are flipped and pasted on the body. The two ends of the strap 6 are provided with corresponding first Velcro 7. The first Velcro 7 includes a first female Velcro and a first female Velcro. When the strap 6 is flipped, the first female Velcro and the first female Velcro are attached. The hinged fixing rods 5 allow the angle of the strap 6 to be adjusted, which can adapt to different head circumferences and wearing angles. The flip-and-paste design of the first Velcro 7 facilitates quick wear and the length is adjustable.

[0049] Example 3

[0050] Different from Embodiment 1, in this embodiment, the second fixing part 8 is an airbag, and a second air valve 18 is provided on the second fixing part 8; the second fixing part 8 being an airbag forms a linkage adjustment with the first fixing parts 1 on both sides, improving the overall adaptability. The air valve structures of the independent air valves on the first fixing part 1 and the second fixing part 8 can achieve hardness grading control of the first fixing part 1 and the second fixing part 8.

[0051] Among them, the state of the second fixing part 8 after inflation is a flat ellipsoid. After the second fixing part 8 is inflated, there is a concave part 13 in the middle.

[0052] In this embodiment, a fourth crease 9 is provided along the transverse central axis of the second fixing part 8. In the deflated state of the second fixing part 8, the second fixing part 8 can be concave along the transverse central axis; the fourth crease 9 is connected to a third fixing part 10 through a connecting member; the connecting member enables flexible expansion of the neck support module, and the fourth crease 9 enables the second fixing part 8 to be concave, which is convenient for the subsequent storage of the expansion module, the third fixing part 10, after being concave.

[0053] Among them, the third fixing part 10 is an airbag, and a third air valve 19 is provided on the third fixing part 10. The shape after inflation is a flat ellipsoid.

[0054] Embodiment 4

[0055] Different from Embodiment 3, in this embodiment, the connecting member includes two connecting bands 11. One end of the connecting band 11 is fixed to the position of the fourth crease 9 on the second fixing part 8, and the other end of the connecting band 11 is fixed to the corresponding side of the third fixing part 10. Length adjustment structures are provided on both of the two connecting bands 11.

[0056] Embodiment 5

[0057] Different from Embodiment 4, referring to the appendix Figure 2 , the length adjustment structure is an adjustment buckle 12. The design of the adjustment buckle 12 can precisely adjust the distance between the third fixing part 10 of the neck support and the second fixing part 8 to adapt to the physiological curvature requirements and body type requirements of different patients; among them, the adjustment buckle 12 is a day-shaped adjustment buckle 12, which is common knowledge well-known to those skilled in the art.

[0058] Embodiment 6

[0059] Different from Embodiment 4, referring to the appendix Figure 1The length adjustment structure is a third hook and loop fastener 16, and the connecting strap 11 is a detachable strap body attached with the third hook and loop fastener 16. The third hook and loop fastener 16 includes a third hook and loop sub-fastener and three third hook and loop female-fasteners. The design of multiple third hook and loop fasteners can adjust the length of the connecting strap 11 according to the needs, thereby accurately adjusting the distance between the third fixing part 10 of the neck support and the second fixing part 8, adapting to the physiological curvature needs and body shape needs of different patients.

[0060] It should be noted that the first air valve 17, the second air valve 18, and the third air valve 19 in this application are similar to the inflation valves on a lifebuoy, and can be connected to an air pump to inflate and deflate the airbag.

[0061] The steps for using a head-supporting pillow are as follows:

[0062] Step 1: The patient lies flat and places the back of the head on the second fixation part 8. At this time, the second fixation part 8 is not inflated and is flat. The sides of the head naturally fit against the first fixation part 1. At this time, the first fixation part 1 is an uninflated cylindrical air bladder.

[0063] Step 2: Inflate the first fixing part 1 on both sides through the first air valve 17 until the cylinder diameter is reached. Visually inspect or ask the patient if it fits the side of the head. If there is no pressure, continue to open the fixing strap 14 to open the first fold 2 and the second fold 3, so that the first fixing part 1 continues to inflate until it fits the curve of the head.

[0064] Step 3: Take the elastic fabric strap 6 and pass both ends of the strap 6 through the fixing rods 5 on both sides. At this time, the strap 6 covers the forehead area. Rotate and adjust the angle of the fixing rods 5, tighten the strap 6 to a moderate pressure, and flip the two ends of the strap 6 in opposite directions so that the Velcro at the end of the strap 6 is firmly bonded to the Velcro on the body.

[0065] Step 4: Inflate the second fixing part 8 through the second air valve 18 until the second fixing part 8 is flattened into an oval shape, and the middle of the second fixing part 8 naturally forms a concave part 13, which conforms to the shape of the back of the patient's head.

[0066] Step 5: Pull out the third fixing part 10 from the recessed part of the fourth fold 9 on the second fixing part 8, and inflate the third fixing part 10 into a flat ellipse. The thickness of the third fixing part 10 can adapt to the physiological curvature of the neck.

[0067] In the usage of this step embodiment 5, pull the H-shaped adjustment buckle 12 on the connecting strap 11 to pull the connecting strap 11 up or down along its length direction and lock it into the H-shaped buckle position, so that the upper edge of the third fixing part 10 supports the position of the patient's shoulder, thereby exposing the carotid artery for easy operation by medical staff.

[0068] In the usage of this step in Example 6, the third Velcro 16 is removed, adjusted to the appropriate position of the third Velcro mother, and reattached so that the upper edge of the third fixing part 10 supports the position of the patient's shoulder, thereby exposing the carotid artery for easy operation by medical staff.

[0069] It should be noted that:
