Description

Technical Field

[0001] The present invention relates to a medical appliance, in particular to a medical protective appliance. Background Art

[0002] The joints and muscles of the human body are important moving parts, and the coordination of various joints and muscles is required to complete the movement. However, frequent use of joints and muscles may cause muscle inflammation or strain, or damage to the ligaments, tendons and other tissues connecting the joints and muscles. During post-injury treatment or rehabilitation, the affected area needs to be fixed and pressurized, and ice or heat compresses are applied according to the situation.

[0003] Traditionally, there is a type of brace that is a piece of fabric. The brace is wrapped around the affected part. In order to ensure that it is firmly fixed and pressurized to a certain pressure, the brace is wrapped around the affected part in multiple layers, and relies on the elastic contraction of the fabric to pressurize the affected part. However, the process of putting on such a brace is very cumbersome and difficult to complete by an individual. When the entire joint is improperly pressurized, it may cause blood circulation problems or discomfort in the affected part. When the discomfort is to be adjusted, the brace often needs to be completely disassembled to adjust it, and the adjustment process is very time-consuming and laborious.

[0004] In order to solve the problems of the traditional protective gear mentioned above, an inflatable protective gear has appeared in the prior art. The inflatable protective gear has a protective gear body, an airbag, an inflation valve, and an air release valve. The airbag is formed in the protective gear body and is connected to the inflation valve and the air release valve. When inflating, an external inflation device is required to inflate the airbag through the inflation valve to achieve the effect of pressurization and fixation. Since the inflation device is an external device separated from the inflatable protective gear, when the user wants to adjust the pressure, the inflation device may not be readily available, making it extremely inconvenient to operate and use. Summary of the invention

[0005] The present invention provides an inflatable pressurized hot and cold compress protective device, which can mainly pressurize and fix joints and muscles to enhance supporting force and accelerate the healing of the affected part.

[0006] To achieve the above objectives, the present invention provides an inflatable pressurized cold and hot compress protective device, which has:

[0007] 1. Protective gear body;

[0008] an air bag formed in the body of the protective gear;

[0009] An inflation and deflation valve is arranged on the protective gear body and connected to the airbag; the inflation and deflation valve can selectively inflate and deflate the airbag.

[0010] Through the above structure, the advantage of the present invention is that the inflated airbag can pressurize and fix the target part to prevent swelling and secondary injury of the target part. And when the target part is over-pressurized, it is only necessary to press the first pressing piece to adjust the air pressure, which can improve the convenience of the user. Since the inflation and deflation valve is installed on the protective gear body, it does not need to rely on an external inflation device, and the inflatable pressurized hot and cold compress protective gear can be inflated and deflated in various scenarios.

[0011] As mentioned above, the inflatable pressurized hot and cold compress protective gear, wherein the inflation and deflation valve has:

[0012] An outer shell, an airflow space is formed inside the outer shell; the airflow space extends in a first direction and is connected to the airbag;

[0013] a first one-way valve disposed in the airflow space; when the first one-way valve moves in the first direction, the outside is connected to the airflow space, and air can pass through the first one-way valve;

[0021] A second elastic member connected to the second pressing portion and pushing the second pressing portion with a restoring force in a direction opposite to the first direction;

[0022] When the first pressing portion drives the first one-way valve to move in the first direction, the first one-way valve pushes the second pressing portion to move in the first direction, so as to drive the second one-way valve to move in the first direction.

[0023] As described above, the inflatable pressurized hot and cold compress protective gear, wherein:

[0024] The outer shell has:

[0025] A first blocking portion, which is disposed around the airflow space;

[0070] Please refer to Figure 1 , Figure 2 , Fig. 9 ,and Fig.10 The present invention provides an inflatable pressurized cold and hot compress protective device, which comprises a protective device body 1, a cold and hot compress belt 2, an air bag 3, an inflation and deflation valve 4, and a reinforcement member 5.

[0071] The protective gear body 1 is used to wrap around joints or muscle parts, such as shoulders, waist, elbows, knees, etc. The hot and cold compress belt 2 is detachably arranged on the protective gear body 1. In this embodiment, the protective gear body 1 has a belt opening. The hot and cold compress belt 2 can be accommodated in the belt opening of the protective gear body 1. In other embodiments, the hot and cold compress belt 2 and the protective gear body 1 can be locked with each other by a Velcro, thereby attaching the hot and cold compress belt 2 to the protective gear body 1, but it is not limited thereto. The hot and cold compress belt 2 includes a single-function cold compress belt or a hot compress belt, or a multifunctional compress belt with cold and hot compress functions.

[0072] The airbag 3 is formed in the protective gear body 1. The shape and distribution of the airbag 3 vary depending on the part of the human body where the inflatable pressurized cold and hot compress protective gear is worn. Figure 3 The first preferred embodiment shown is an inflatable pressurized cold and hot compress protective device worn on the knee, and the airbag 3 is located on the front side of the knee. The airbag 3 is in a strip shape around the kneecap and extends to the thigh and calf. Therefore, when the airbag 3 is inflated and pressurized, direct compression of the kneecap can be avoided, and the fixation and support of the knee joint can be strengthened.

[0073] Another example Figures 9 to 11The second preferred embodiment shown is an inflatable pressurized hot and cold compress protective device worn on the waist, and the airbag 3 is located on the back. The airbag 3 includes two sheet-like airbags with larger areas located on both sides, and a columnar airbag in the center along the length of the spine, and the sheet-like airbags are connected to the columnar airbags. Therefore, when the airbag 3 is inflated and pressurized, the sheet-like airbags on both sides can pressurize and fix the muscle groups supporting the spine, such as the spinal cord muscles, and the columnar airbag in the center provides support for the spine. Fig.12 The third preferred embodiment shown is an inflatable pressurized hot and cold compress protector worn on the shoulder, and the airbag 3 is located on the upper deltoid muscle of the shoulder to limit the excessive shoulder abduction of the wearer.

[0074] Please refer to Figure 1 The inflation and deflation valve 4 is arranged on the protective gear body 1 and connected to the airbag 3. The inflation and deflation valve 4 can selectively inflate and deflate the airbag 3. When the airbag 3 is inflated, the protective gear body 1 can be expanded and the protective gear body 1 is less likely to bend and deform, thereby pressurizing and fixing the target part, and making the hot and cold compress belt 2 fit the target part more completely.

[0075] Please refer to Figure 4 and Figure 5 The inflation / deflation valve 4 comprises an outer shell 40 , a first one-way valve 41 , a second one-way valve 42 , an inflation portion 43 , a first pressing portion 44 , a first elastic member 45 , a second pressing portion 46 , and a second elastic member 47 .

[0076] An airflow space is formed inside the outer shell 40. The airflow space extends toward the airbag 3 in a first direction and is selectively connected to the airbag 3. The outer shell 40 has a first blocking portion 401 and a second blocking portion 402. The first blocking portion 401 is disposed around the airflow space. The second blocking portion 402 is disposed around the airflow space and is separated from the first blocking portion 401 in a first direction.

[0077] The first one-way valve 41 is disposed in the airflow space and includes a first plate 411. In this embodiment, the first plate 411 is movable, and thus the first plate 411 can selectively abut against the first blocking portion 401 or separate from the first blocking portion 401. When the first one-way valve 41 moves in the first direction, the first plate 411 separates from the first blocking portion 401, allowing air to flow through the first one-way valve 41. In other embodiments, the first plate 411 is fixed, but may be bent and deformed by air pressure or airflow. For example, when the pressure in the airflow space is lower than the external air pressure, the first plate 411 bends and deforms, so that the first plate 411 separates from the first blocking portion 401, thereby allowing air to flow through the first one-way valve 41.

[0078] The second one-way valve 42 is arranged in the airflow space at a distance from the first one-way valve 41 in the first direction, and includes a second plate 421. In this embodiment, the second plate 421 is movable, and thus the second plate 421 can selectively abut against the second blocking portion 402 or separate from the second blocking portion 402. When the second one-way valve 42 moves in the first direction, the second plate 421 separates from the second blocking portion 402, allowing air to flow through the second one-way valve 42. In other embodiments, the second plate 421 is fixed, but can be bent and deformed by air pressure or airflow, thereby allowing air to enter the airbag 3 through the second one-way valve 42.

[0079] The inflatable portion 43 is a hollow shell and connects the airflow space between the first one-way valve 41 and the second one-way valve 42. Figure 6 When the inflatable part 43 is subjected to a squeezing force, the inflatable part 43 will be flattened and the air in the hollow shell will be sent to the airflow space. The air will push the second one-way valve 42 away from the second blocking part 402 from the first direction and enter the airbag 3. The inflatable part 43 is made of a highly elastic material. Figure 7 When the squeezing force is released, the compressed inflatable part 43 will rebound to its original state by the elastic restoring force of its own material, and at the same time, the air pressure in the hollow shell of the inflatable part 43 is lower than the external air pressure, so that the external air will enter the airflow space and push the first one-way valve 41 away from the first blocking part 401, and enter the inflatable part 43, so that the inflatable part 43 is filled with air again. In this way, the user can repeatedly press the inflatable part 43 to continuously fill the airbag 3 with air.

[0080] Please refer to Figures 5 to 8 The first pressing portion 44 is connected to the first one-way valve 41. The first pressing portion 44 can drive the first one-way valve 41 to move in the first direction. The first elastic member 45 is connected to the first pressing portion 44, and the restoring force of the first elastic member 45 pushes the first pressing portion 44 in the opposite direction to the first direction. The second pressing portion 46 is connected to the second one-way valve 42. The second pressing portion 46 can drive the second one-way valve 42 to move in the first direction. The second elastic member 47 is connected to the second pressing portion 46, and the restoring force of the second elastic member 47 pushes the second pressing portion 46 in the opposite direction to the first direction.

[0081] like Figure 8When the airbag 3 is inflated and the user presses the first pressing portion 44 to drive the first one-way valve 41 to move in the first direction, the first one-way valve 41 will separate from the first blocking portion 401 and push the second pressing portion 46 to move in the first direction, so as to drive the second one-way valve 42 to move in the first direction and separate from the second blocking portion 402, thereby connecting the airbag 3, the airflow space, and the outside world at the same time, so that the gas in the airbag 3 can flow out of the airbag 3 after being pressurized. When the inflatable pressurized hot and cold compress protective gear is worn, the target part will be subjected to the reaction force of the pressurization of the inflatable pressurized hot and cold compress protective gear, so the user only needs to press the first pressing portion 44 to achieve the deflation effect at one time.

[0082] Please refer to Figure 3 and Fig.11 The reinforcement 5 is an elastic belt that can be wrapped around the protective gear body 1. In this embodiment, the end of the reinforcement 5 and the belt body of the reinforcement 5 or the protective gear body 1 can be locked with each other by a Velcro tape, and the reinforcement 5 can be wrapped and pressurized on the target part by its own elasticity, and the end of the reinforcement 5 is attached to the belt body of the reinforcement 5 or the protective gear body 1. In this way, the inflatable pressurized cold and hot compress protective gear can be wrapped more firmly.

[0083] Please refer to Figures 5 to 8 When the user wears the inflatable pressurized hot and cold compress protective gear, the protective gear body 1 is wrapped around the target part. Then the inflatable part 43 is repeatedly pressed to pump air into the airbag 3. When the user wants to adjust the air pressure, the first pressing part 44 is continuously pressed, and the airbag 3 will be continuously deflated. When the air pressure reaches the appropriate level, the pressing of the first pressing part 44 can be stopped.

[0084] The present invention is not limited to the first preferred embodiment, the second preferred embodiment, and the third preferred embodiment. In other embodiments, it can be applied to more target parts, such as wrists, elbows, ankles, or necks, and the inflation and deflation valves 4 are installed at positions that are convenient for users to operate, and the shape of the airbags 3 varies according to the muscle distribution or bone structure of the target parts.

[0085] The advantage of the present invention is that the inflated airbag 3 can pressurize and fix the target part to prevent swelling and secondary injury of the target part, and can make the hot and cold compress belt 2 fit the target part more closely, achieving a better temperature transfer effect. When excessive pressure is applied to the target part, only the first pressing part 44 needs to be pressed to adjust the air pressure, which can improve the convenience of the user. Since the inflation and deflation valve 4 is installed on the protective gear body 1, it does not need to rely on an external inflation device, and the inflatable pressurized hot and cold compress protective gear can be inflated and deflated at will in various scenarios.
