Description

Lip spreader

This creation relates to a medical rehabilitation device, especially a patient who can be used for chewing, dysphagia, or language disorders caused by injury, stroke, or other factors, so that the patient can use the rehabilitation device to recover the oral cavity and Lip function for normal function of lip muscle and cheek muscle.

At present, there are many sports equipment on the market to prevent the aging of muscles in various parts of the body, but there is no equipment to prevent the aging of muscles in the face and mouth. Therefore, it is difficult to effectively improve drooling, swallowing difficulties, and speech failure caused by stroke To be clear about other symptoms, dysphagia refers to difficulties in the movement of food from the mouth to the stomach. Generally speaking, the swallowing action can be divided into oral preparation period, oral period, pharyngeal period and esophageal period. Every period has the opportunity to cause swallowing abnormalities. This book focuses on helping cases of oral swallowing abnormalities during oral preparation and oral phases. This period of cases is easy to incorporate problems such as insufficient lip tension and insufficient cheek tension ... etc. Therefore, in order to increase the muscle tension of the cheeks, the person must perform facial movements, including a round mouth with a strong / lip shape and a mouth shape with the lips stretched to / 1 /, and repeat these two actions quickly, so that you can Increase the tension of the cheek muscles. However, there are also some cases where the muscle strength is insufficient to exercise. To prevent contractures, massage or active movement can be used to expand the range of movement. In addition to the above, this equipment is also needed for cases where the mouth cannot open by itself or the bite reflex is strong.

With current technology, patients with hemiplegia caused by cerebral congestion are often accompanied by involuntary drooling, unconsciously making food fall, difficulty swallowing, and unclear symptoms during chewing. Generally, the rehabilitation of the muscles around the oral cavity is performed; however, the aforementioned rehabilitation work, Republic of China Patent Application No. 87215548 "Buccous Rehabilitation Structure" patent case, in order to solve the above problems, its structure is a The upper lip placement part, the lower lip placement part, and the buccal muscle rehabilitation device constructed by the elastic connection part connected to the upper and lower lip placement parts, using the above rehabilitation device, the elasticity of the connection part is used to increase The mouth and cheek muscles are moderately burdened, and the muscles around the mouth are light for effective rehabilitation work.

The end of each protrusion of the second lip is a round lead angle and there is an inner space between each protrusion A second arc-shaped concave groove (123a, 123b); and a support member (21), which is detachably connected to the elastic body, and the support member is formed to be perpendicular to the protruding direction of the first lip Or arranged in a mutually perpendicular direction with the protruding direction of the second spreading lip to press against the upper lip so that the oral cavity is stretched up and down; wherein a pair of protrusions (111 ) Of The axial distance of is different from the axial distance of another pair of protrusions (112), which is used to form different outward expansion forces for the muscles on the left and right sides of the lips; one of the protrusions of the second lip The axial spacing between (121) is different from the axial spacing of another pair of protrusions (122), which is used to form different outward expansion forces for the muscles on the left and right sides of the lips. The lip spreader as described in item 2 of the patent application scope, wherein the elastic body is provided with a slot (13) penetrating through the elastic body, the support member is a half-moon-shaped structure and extends outward with a pivot Part (210), the supporting part is embedded in the slot with the pivot part, and the supporting part is rotated around the center of the slot to form an axis to change the position of the upper lip against the top to adjust Open the size of the mouth. A lip spreader as described in item 3 of the patent application scope, wherein one end of the support member has a notch portion (212), and the support member has an end with the notch portion against the upper lip, so that the support member Form fixed. The lip spreader as described in any one of patent application scopes 1 to 4, wherein the elastic system is a thermoplastic elastomer (TPE). The lip spreader according to any one of the patent application scopes 1 to 4, wherein the axial distance between the pair of protrusions (111) of the first lip is defined as a first expansion distance (d1 ), The axial distance between another pair of protrusions (112) is defined as a second expansion distance (d2), the axial distance between one pair of protrusions (121) of the second spreading lip It is defined as a third expansion distance (d3), and the axial distance between another pair of protrusions (122) is defined as a fourth expansion distance (d4). These expansion distances satisfy the following conditions: The first expansion The distance (d1) is smaller than the second expansion distance (d2); and the third expansion distance (d3) is smaller than the fourth expansion distance (d4). The lip spreader as described in item 6 of the patent application scope, wherein the third expansion distance (d3) is less than or equal to the first expansion distance (d1); Expansion distance (d2). The lip spreader as described in any one of the patent application scopes 1 to 4, wherein the bottom surface of the first arc-shaped groove is semicircular and extends from the bottom surface toward the two ends to connect the ends of the protrusions, At least one pair of protrusions respectively disposed at two ends of the first arc-shaped groove protrude outward from the elastic body slightly away from each other, and the bottom surface of the second arc-shaped groove is semicircular and The bottom surface extends toward the two ends and connects the ends of the protrusions. At least a pair of protrusions respectively disposed at the two ends of the second arc-shaped groove protrude outward from the arc-shaped protrusion slightly away from each other Stretch. The lip spreader as described in item 8 of the patent application scope, wherein the protrusions (111a, 112a, 111b, 112b) respectively disposed at the two ends of the first arc-shaped groove form a first clamping portion (110a , 110b), used to clamp the inner and outer sides of the oral cavity to form a fixed, and the protrusions respectively disposed at the two ends of the second arc-shaped groove form a second clamping portion (120) for clamping the internal and external oral cavity Fixed on both sides. The lip spreader as described in item 1 or 2 of the patent application, which further includes a storage slot (14), the storage slot penetrates the elastic body and is located on the first lip and the second lip In the position between them, the storage slot is an elongated groove and its two sides extend outward at an oblique angle (θ), and the oblique angle is between 30 and 45 degrees.
