Description

Technical Field

[0001] The utility model relates to hand and foot covers, and more specifically to an improved air pressure inflatable hand and foot cover. Background Art

[0002] In daily life, people with injured hands and feet are often seen. During the treatment and recovery stage, they often need external equipment to fix and apply pressure to their hands and feet. The common methods are splints or plasters, but some patients are not suitable for wrapping the entire upper or lower limbs. Often, only the patient's hands or feet need to be fixed and pressed. Therefore, air bag fixation and pressure have come into being. However, there are currently no hand and foot sleeves designed for hands and feet. Therefore, the utility model provides an improved air pressure inflatable hand and foot sleeve, which can be used for patients with lower limb fractures, ankle fractures or long-term bedridden patients, especially patients with limb wounds. It can promote blood circulation in the lower limbs and prevent deep vein thrombosis in the lower limbs. Utility Model Content

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be combined with the technical solution in the embodiments of the utility model for a clear and complete description. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] An improved air pressure inflatable hand and foot cover, comprising a cover 1 for wrapping around the hands and feet, the cover 1 is preferably made of polyester cloth, the overall shape of the cover 1 is preferably a triangle, and the triangle shape of the cover can adapt to the shape of the hand, and an air bag 3 is provided at the end of the cover 1 close to the skin, and the air bag 3 is made of PVC, rubber or TPU inner bag.

[0021] PVC

[0022] PVC has the characteristics of light weight, heat insulation, thermal insulation, moisture resistance, flame retardancy, and easy construction. Durability: PVC pipes can withstand high pressure and high temperature, and are not easily affected by chemical corrosion and abrasion, so they have a long service life in various applications.

[0023] TPU

[0024] TPU is a very environmentally friendly material with very good recyclability. It also has excellent high tension, high pulling force, strong and aging resistance, and is widely used in medical and health, electronic appliances, industry and sports. TPU is mainly divided into polyester and polyether types, with a wide hardness range of 60HA-85HD, and has the characteristics of wear resistance, oil resistance, transparency and good elasticity. TPU is a material with elasticity between rubber and plastic, and has good resistance to oil, mineral oil, animal and plant fats and lubricants and many solvents. It also has good weather resistance and excellent resistance to high-energy rays.

[0025] So it is very durable

[0026] rubber

[0027] 1) High elasticity: low elastic modulus, large elongation deformation, recoverable deformation, and can maintain elasticity in a wide temperature range (-50 ~ 150 ° C),

[0028] 2) Tensile strength: also known as tear strength or tensile strength, it refers to the load per unit cross section when the specimen is stretched to break. The unit is megapascal (Mpa), which was previously kilogram force per square centimeter (kgf / cm2).

[0029] 3) Tear strength: The load per unit thickness when a special test piece (with a cut or right angle) is torn, indicating the tear resistance of the material, with the unit of kN / m.

[0030] 4) Elongation at break: When the specimen is broken, the ratio of the elongated part to the original length is called elongation, which can be expressed as a percentage.

[0031] 5) Resilience: Also known as impact elasticity, it refers to the ability of rubber to recover to its original shape after being impacted, expressed as a percentage. 6) Hardness: It refers to the ability of rubber to resist external pressure, usually measured by a Shore durometer. The hardness range of rubber is generally between Shore A20-100.

[0032] The wrapping sleeve 1 is provided with a strap 2, and the strap 2 is preferably made of polyester cloth. A certain angle is set between the strap 2 and the wrapping sleeve 1. By utilizing the angle, when wrapping the hand, the strap 2 can be wrapped around the base of the thumb, so that the device can be worn stably and prevented from falling off. When wrapping the foot, the strap 2 is wrapped around the foot, and a triangle is formed by the angle between the strap 2 and the wrapping sleeve 1. By utilizing the stability of the triangle, the device can be worn more stably.

[0033] The wrapping cover 1 is provided with a first Velcro 5 on one side of the airbag 3, and the first Velcro 5 is provided at a position away from the strap 2. The strap 2 is provided with a second Velcro 6 at a position away from the wrapping cover 1. The wrapping cover 1 is provided with a third Velcro 7 on the side away from the airbag 3 for cooperating with the first Velcro 5 and the second Velcro 6 to fix the device. The third Velcro 7 is in a long strip shape, and its length is slightly smaller than the length of the wrapping cover 1. When the device is in use, the device is wrapped around the hand or foot, and the first Velcro 5 is firstly pasted on the third Velcro 7, and then the strap 2 is wrapped around the second Velcro 6 to cooperate with the third Velcro 7, so as to fix the device.

[0034] The airbag 3 is connected to an air tube 4, and one end of the air tube 4 away from the airbag 3 is connected to an external inflation device. One side of the airbag 3 is fixed to the wrapping sleeve 1. With this arrangement, the airbag 3 can be flipped on the wrapping sleeve 1, which is convenient for cleaning and disinfecting the device after use.

[0035] Example 2

[0036] The difference between this embodiment and embodiment 1 is only the installation method of the airbag 3. In this embodiment, a mounting sleeve is provided on the outside of the airbag 3. The mounting sleeve is preferably made of flannel. An opening for loading and removing the airbag 3 is provided on the mounting sleeve. The mounting sleeve can facilitate the installation and removal of the airbag 3, so that the device can be cleaned and disinfected except for the airbag 3 and the trachea 4 by washing.

[0037] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
