Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an air pressure therapeutic apparatus. Background Art
[0002] A pneumatic therapy device is a medical device that operates by sequentially and repeatedly inflating and deflating a multi-chamber airbag to create circulatory pressure on limbs and tissues. This circulatory pressure applies uniform and orderly compression from distal to proximal extremities, promoting blood circulation, preventing thrombosis, and improving lymphatic drainage, thereby accelerating tissue repair and alleviating symptoms such as swelling. During use, the airbag is in direct contact with the patient's skin. Due to prolonged use and potential sweat and medication residue, the airbag tends to become dirty. This contamination not only affects the aesthetics and comfort of the device but, more importantly, can serve as a carrier of pathogens, increasing the risk of cross-infection. Traditional airbag designs often utilize a monolithic structure, which presents significant cleaning challenges. Due to wrinkles and corners within the airbag, these areas are often difficult to clean thoroughly, allowing pathogens to remain and increasing the risk of infection. Utility Model Content

DETAILED DESCRIPTION
[0020] The present invention will be further described below with reference to the accompanying drawings:
[0021] Please attend Figure 1 、 Figure 2 ,as well as Figure 3The utility model is a pneumatic therapy device, comprising a main unit 1, a tracheal assembly 2 connected to the main unit 1, and an airbag limb sleeve 3 connected to the tracheal assembly 2. The tracheal assembly 2 comprises a main pipe 21 and a plurality of branch tracheae 22, and the airbag limb sleeve 3 comprises a plurality of airbags 31 enclosed and sleeved on the patient's limbs. The plurality of airbags 31 are connected one-to-one with the plurality of branch tracheae 22. The two ends of the airbags 31 are detachably enclosed and each two adjacent airbags 31 are detachably connected. The design of multiple airbags 31 allows them to be disassembled one by one after use, and a single airbag 31 can also be opened at the same time, which makes it more convenient for medical staff to perform deep cleaning and disinfection of the interior, prevents residual bacteria after use by different patients, and reduces the risk of infection for patients. At the same time, the detachable airbags 31 can also avoid the patient's painful area during use, reducing the patient's treatment pain.
[0022] When in use, first, the air bag 31 is sheathed on the patient's limbs. In the present embodiment, a first Velcro fur surface 311 is provided at one end of the air bag 31, and a first Velcro thorn bristle surface 312 adapted to the first Velcro fur surface 311 is provided at the other end of the air bag. The air bag 31 is enclosed and connected to form a cylindrical structure by the first Velcro fur surface 311 and the first Velcro thorn bristle surface 312. The area of the coverage of the first Velcro fur surface 311 and the first Velcro thorn bristle surface 312 can be designed to be relatively large, so that when the air bag 31 is sheathed, the connection between the first Velcro fur surface 311 and the first Velcro thorn bristle surface 312 can be adjusted according to the length of the patient's limbs, making it convenient for patients with different limb sizes to use. Since there is a certain amount of swelling on the limbs of patients using the air pressure therapy device, in order to make the patient more comfortable, a skin-friendly layer (not shown) is provided on the side of the air bag 31 close to the patient's limbs. When the air bag 31 is sheathed on the patient's limbs, the skin-friendly layer contacts the patient's skin to increase the patient's comfort. To prevent the airbag 31 from sliding during inflation and deflation, an anti-slip strip 6 is provided on the inner side of the airbag 31, closest to the patient's limb. This anti-slip strip 6 increases friction with the patient's skin, preventing the airbag 31 from sliding. Because the airbag 31 wraps around the patient's limb, the patient's skin is prone to sweating. To enhance ventilation, the outer surface of the airbag 31 is made of a breathable and waterproof material.
[0023] After the first airbag 31 is installed, the second airbag 31 is then enclosed and docked to the first airbag 31. To facilitate connection, the inner surface of one side of the airbag 31 is provided with a second Velcro surface 313, and the outer surface of the other side of the airbag 31 is provided with a Velcro bristle surface 314 that matches the second Velcro surface 313. The two adjacent airbags 31 are detachably connected via the second Velcro surface 313 and the second Velcro bristle surface 314. In use, during the enclosed connection process of the second airbag 31, the second Velcro surface 313 in the second airbag 31 is bonded to the second Velcro bristle surface 314 in the first airbag 31. Since the diameter of the patient's limb gradually increases from small to large, in order to enable the latter airbag 31 to cover the previous airbag 31 when connected, in this embodiment, the length of the airbag 31 gradually increases or decreases from the first to the last length. The design of docking multiple airbags 31 allows them to be disassembled one by one after use, making it more convenient for medical staff to perform deep cleaning and disinfection, preventing residual bacteria and reducing the risk of infection for patients. When connecting, the airbags can also avoid the patient's painful area during use, reducing the patient's treatment pain.
[0024] Please continue to see Figure 4 as well as Figure 5After the airbags 31 are docked, the branch air tubes 22 need to be connected to the airbags 31 one by one. Therefore, each airbag 31 is provided with an inflation connector 4 that connects to the branch air tube 22. To facilitate connection and fixation, the branch air tube 22 is provided with a connecting end 221 at the end near the inflation connector 4. The connecting end 221 has a plug section 2211 closer to the inflation connector 4 and a threaded section 2212 farther from the inflation connector 4. The end of the inflation connector 4 closer to the branch air tube 22 is provided with an insertion groove 41 for the plug section 2211 to be inserted into. A one-way stopper 411 is provided on the outer periphery of the inflation connector 4, located on the end of the insertion groove 41 farther from the branch air tube 22. A threaded sleeve 5, which is threadedly connected to the threaded section 2212, is slidably connected to the outer periphery of the inflatable connector 4. The end of the threaded sleeve 5, away from the branch air pipe 22, is provided with a mating portion 51 that engages with a one-way stopper 411 to prevent the threaded sleeve 5 from separating from the inflatable connector 4 in the direction of the branch air pipe 22. When the branch air pipe 22 is docked with the inflatable connector 4, the threaded sleeve 5 is slid to the position of the threaded section 2212 and then rotated to securely connect the branch air pipe 22 to the inflatable connector 4. This process only requires rotating the threaded sleeve 5. The threaded connection ensures a tighter connection between the branch air pipe 22 and the inflatable connector, making it less likely to fall off. To ensure better airtightness and prevent air leakage after the plug-in section 2211 is inserted into the plug-in slot 41, a sealing gasket 412 is provided within the plug-in slot 41. Specifically, the sealing gasket is set at the bottom of the plug-in slot 41. When the plug-in section 2211 is inserted into the plug-in slot 41, the sealing gasket 412 abuts against the end face of the plug-in section 2211 away from the branch air pipe 22. At this time, the sealing gasket 412 will be compressed and fill any possible tiny gaps, thereby improving the sealing effect.
[0025] In this embodiment, the insertion groove 41 and the inflatable connector 4 are integrally formed. To prevent the threaded sleeve 5 from detaching from the inflatable connector in the direction of the branch air pipe 22, the outer diameter of the insertion groove 41 is adapted to the outer diameter of the threaded section 2212 and is larger than the outer diameter of the inflatable connector 4, so that a step portion is formed between the outer wall surface of the insertion groove 41 and the outer wall surface of the inflatable connector 4. The step portion forms a one-way limiter 411 for limiting the threaded sleeve 5 from detaching from the branch air pipe 22. At the same time, the threaded sleeve 5 has a large-diameter section 52 that is closer to the branch air pipe 22 and has an inner diameter that is adapted to the insertion groove 41 and the threaded section 2212, and a small-diameter section (not shown) that is further away from the branch air pipe 22. The inner wall of the large-diameter section 52 is distributed with internal threads that are threadedly connected to the threaded section 2212. A step portion is formed between the small-diameter section 53 and the large-diameter section 52, and the step portion forms a mating portion 51 that is limited by the one-way limiter 411. When the threaded sleeve 5 is rotated toward the branch air pipe 22 to a certain position, due to the stepped portion formed between the small-diameter section and the large-diameter section 52, when the large-diameter section 52 moves to a certain position, the side wall of the small-diameter section will abut against the end of the insertion groove 41 away from the branch air pipe 22, that is, the mating portion 51 abuts against the one-way limiter 41, and the threaded sleeve 5 cannot move further. At the same time, the insertion groove 41 cannot be withdrawn from the threaded sleeve 5, and the connection is relatively stable.
[0026] The above are merely examples of the present invention, and the well-known specific structures and characteristics of the scheme are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these modifications should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention and the practicality of the present invention.
