The cervical pillow comprises a substrate and an upper cover, the substrate is used for making contact with the back of a person, and the upper cover is arranged on the substrate in a sliding mode and used for making contact with the head of the person; when a person sleeps, the upper cover slides downwards relative to the substrate under the gravity action of the head, so that the cervical vertebra of the person is drafted in the longitudinal direction, and the longitudinal direction is the straight line direction in which the body of the person extends. According to the scheme, the cervical vertebra can be drafted in the longitudinal direction, and therefore cervical vertebra patients needing drafting can be effectively treated.

Description

Technical Field

[0001] The present invention relates to the technical field of pillows, and particularly to a cervical pillow capable of longitudinal stretching. Background Art

[0002] Under normal circumstances, the cervical vertebrae of a person have a certain forward curvature, i.e., the physiological curvature. The frequency of modern people using computers and mobile phones is increasing continuously. Prolonged head-down posture often leads to the reduction, disappearance or even reverse curvature of the cervical physiological curvature, and often develops into cervical spondylosis and extraforaminal nerve compression over time. Patients often show soreness in the head, neck and shoulder and back, limited neck movement, and in severe cases, symptoms such as weakness in the upper limbs, numbness in the fingers, dizziness, etc., seriously affecting the quality of life. Cervical pillows can often be used for treatment, and correction can be completed during daily sleep, with good convenience.

[0003] A cervical pillow can provide appropriate support for the neck, help maintain the physiological curvature of the cervical vertebrae, and reduce neck pressure. Using a cervical pillow can reduce neck fatigue and discomfort and improve sleep quality. Correct selection and use of a cervical pillow helps prevent the occurrence of cervical spondylosis and other neck problems. Stretching can relieve muscle spasm, expand the intervertebral space, and reduce the compression of the intervertebral disc on other tissues, thereby relieving pain, and is a commonly used method for the treatment of cervical spondylosis. However, the current cervical pillows do not provide enough stretching for the cervical vertebrae in the longitudinal direction (i.e., the straight line direction of the body extension), so that they cannot effectively treat cervical patients who need stretching. Summary of the Invention

[0004] An embodiment of the present invention provides a cervical pillow capable of longitudinal stretching, which can achieve the longitudinal stretching of the cervical vertebrae, so as to effectively treat cervical patients who need stretching.

[0005] An embodiment of the present invention provides a cervical pillow capable of longitudinal stretching, comprising:

[0006] A substrate for contacting with a person's back;

[0007] An upper cover slidably disposed on the substrate for contacting with a person's head;

[0008] When a person is sleeping, the upper cover slides downward relative to the substrate under the action of the gravity of the head, so as to achieve the longitudinal stretching of the person's cervical vertebrae, and the longitudinal direction is the straight line direction of the person's body extension.

[0009] Preferably, when the substrate is made of an airbag, the height of the substrate is adjustable, and the height direction of the substrate is perpendicular to the longitudinal direction.

[0010] Preferably, the substrate includes a horizontally arranged first bottom surface, a top surface inclined relative to the first bottom surface, and a first curved surface inclined relative to the first bottom surface. The top surface contacts the second bottom surface of the upper cover, and relative sliding can occur between the two. The first curved surface is for contacting a person's back, and a second curved surface arranged above the upper cover is for contacting a person's head.

[0011] Preferably, a self-lubricating material is coated between the top surface and the second bottom surface.

[0012] Preferably, the self-lubricating material includes any one of polyethylene, polytetrafluoroethylene, polyoxymethylene, and polyester resin.

[0013] Preferably, one of the top surface and the second bottom surface is provided with a groove, and the other is provided with a protrusion. The protrusion is slidably arranged in the groove.

[0014] Preferably, an elastic member is arranged in the groove. The elastic member abuts against the protrusion. When a person's head contacts the second curved surface, the elastic member is compressed. When the person's head leaves the second curved surface, the elastic member drives the upper cover to return to the initial position.

[0015] Preferably, a connecting rod inclined relative to the first bottom surface is arranged in the substrate. The first end of the connecting rod abuts against the upper cover, and the second end extends out of the first curved surface. The second end is for contacting a person's back to push the connecting rod to drive the upper cover to slide downward.

[0016] Preferably, the upper cover is made of silica gel or latex.

[0017] The embodiment of the present invention provides a cervical pillow capable of longitudinal stretching. By arranging a substrate and a slidable upper cover on the substrate, when a person sleeps, due to the gravity of the head, the upper cover slides downward relative to the substrate, so as to realize the longitudinal stretching of a person's cervical vertebra, and thus can effectively treat cervical vertebra patients in need of stretching.

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figures 1 to 5 shown, the embodiments of the present invention provide a longitudinally stretchable cervical pillow, including:

[0038] A substrate 1 for contacting with a person's back;

[0039] An upper cover 2 slidably disposed on the substrate 1 for contacting with a person's head;

[0040] When a person is sleeping, due to the gravitational force of the head, the upper cover 2 slides downward relative to the substrate 1 to achieve longitudinal stretching of the person's cervical vertebrae. The longitudinal direction is the straight line direction of the person's body extension (i.e., Figure 5 the left - right direction in

[0041] In this embodiment, by providing the substrate 1 and a slidable upper cover on the substrate 1, when a person is sleeping, due to the gravitational force of the head, the upper cover 2 slides downward relative to the substrate 1 to achieve longitudinal stretching of the person's cervical vertebrae, thereby effectively treating cervical vertebra patients who need stretching.

[0042] It should be noted that the longitudinally stretchable cervical pillow provided by the embodiment of the present invention is suitable for patients with cervical degenerative arthritis (cervical spurs) or intervertebral disc herniation complicated with nerve root compression, but not suitable for patients with spinal cord injury, blood vessel compression, etc. caused by cervical vertebra dislocation.

[0043] In an embodiment of the present invention, the substrate 1 is made of plastic, wood or an airbag, and the specific material of the substrate 1 is not limited herein.

[0044] In an embodiment of the present invention, when the substrate 1 is made of an airbag, the height of the substrate 1 (i.e., Figure 1 the h shown) is adjustable, and the height direction of the substrate 1 is perpendicular to the longitudinal direction.

[0045] It can be understood that by adjusting the height of the substrate 1, the gap of the cervical vertebrae can be initially improved. For example, by lowering the height, the gap of the cervical vertebrae can be increased. Moreover, the airbag can adapt to people with different cervical curvatures and different back thicknesses.

[0046] In an embodiment of the present invention, the substrate 1 includes a horizontally arranged first bottom surface 11, a top surface 12 inclined relative to the first bottom surface 11, and a first curved surface 13 inclined relative to the first bottom surface 11. The top surface 12 contacts the second bottom surface 21 of the upper cover 2, and the two can slide relative to each other. The first curved surface 13 is used to contact the person's back, and the second curved surface 22 arranged above the upper cover 2 is used to contact the person's head.

[0047] In this embodiment, by inclinedly arranging the top surface 12 above the first bottom surface 11, it is beneficial for the top surface 12 and the second bottom surface 21 of the upper cover 2 to more easily slide relative to each other, thereby being beneficial for the longitudinal stretching of the cervical vertebrae.

[0048] In some embodiments, both the top surface 12 and the second bottom surface 21 can be planes or curved surfaces, and specific limitations are not made herein.

[0049] In an embodiment of the present invention, a self-lubricating material is coated between the top surface 12 and the second bottom surface 21, so that the friction between the two can be reduced, which is conducive to relative sliding due to the weight of the head. It should be noted that the self-lubricating material is a material without viscosity, and its purpose is to reduce the friction between two contact surfaces.

[0050] In some embodiments, self-lubricating layers 3 can be provided on the surfaces of the top surface 12 and the second bottom surface 21, and the self-lubricating layer 3 is a surface layer formed by the self-lubricating material.

[0051] In an embodiment of the present invention, the self-lubricating material includes any one of polyethylene, polytetrafluoroethylene, polyoxymethylene, and polyester resin, and no specific limitation is made thereto herein.

[0052] In an embodiment of the present invention, a groove 14 is provided on one of the top surface 12 and the second bottom surface 21, and a protrusion 23 is provided on the other. The protrusion 23 is slidably disposed in the groove 14.

[0053] For Figure 3 and 4 example, the top surface 12 is provided with a groove 14, and the second bottom surface 21 is provided with a protrusion 23.

[0054] In an embodiment of the present invention, an elastic member (not shown in the figure) is provided in the groove 14. The elastic member abuts against the protrusion 23. When a person's head touches the second curved surface 22, the elastic member is compressed, and when the person's head leaves the second curved surface 22, the elastic member drives the upper cover 2 to return to the initial position.

[0055] In this embodiment, by providing an elastic member in the groove 14, it is convenient for the elastic member to drive the upper cover 2 to return to the initial position when a person's head leaves the second curved surface 22, so as to be further supplied for different people to use.

[0056] In some embodiments, the elastic member can be a spring, and no specific limitation is made thereto herein.

[0057] In an embodiment of the present invention, a connecting rod 4 inclined relative to the first bottom surface 11 is provided in the substrate 1. The first end of the connecting rod 4 abuts against the upper cover 2, and the second end extends out of the first curved surface 13 (that is, the second end protrudes from the first curved surface 13 to be conducive to contacting the back). The second end is used to contact a person's back to push the connecting rod 4 to drive the upper cover 2 to slide downward.

[0058] In this embodiment, if the stretching cannot be effectively achieved by relying on the weight of the head, then the pressure of the back can be relied on to press the second end of the connecting rod 4, so as to further drive the upper cover 2 to slide downward.

[0059] In an embodiment of the present invention, the upper cover 2 is made of silica gel or latex, and no specific limitation is made thereto herein.
