Description

Technical Field

[0001] This utility model relates to the field of wound treatment technology, and in particular to an oxygen wound treatment device. Background Technology

[0002] Wound treatment is a comprehensive process aimed at promoting wound healing and reducing complications such as infection.

[0003] There are many types of wound treatment. When using oxygen for wound treatment, current hospitals lack dedicated equipment and rely on oxygen masks for direct oxygen delivery. Existing oxygen masks are connected to an oxygen generator via tubing. When using them, nurses need to hold the mask directly over the wound, which is inconvenient. Furthermore, due to manual operation, the distance between the mask and the wound is uncontrollable, increasing the risk of injury. Oxygen wound treatment also takes a long time, leading to considerable fatigue for nurses.

[0004] Chinese utility model patent (CN220676503U) discloses a wound oxygen therapy device, including an oxygen therapy mask. Fixing straps are fixedly connected to both sides of the mask's surface. A fixing hole is formed on one side of the mask's surface, and a sensing component is fixedly connected inside the hole. An oxygen tube is connected to the center of the mask's surface, and one end of the oxygen tube is connected to a cover plate. A heating chamber is snapped onto the bottom of the cover plate. A cavity is formed in the inner wall of the heating chamber, and a heating component is inserted into the cavity. An oxygen inlet pipe is connected to one side of the top surface of the cover plate. This wound oxygen therapy device, through the heating component, allows the oxygen generator to deliver oxygen into the heating chamber via the oxygen inlet pipe. Connecting to an external power source powers the heating element, and a temperature controller controls the heating temperature of the heating element to heat the flowing oxygen, preventing cold oxygen from blowing directly onto the patient's wound and causing discomfort. This patented method of securing the oxygen therapy mask to the patient with a strap results in the oxygen therapy mask being too close to the patient, creating high air pressure, which can easily cause secondary damage to the wound. Furthermore, the oxygen therapy mask can compress the patient, causing further injury to the wound and contaminating the oxygen therapy mask. Utility Model Content

[0030] Example 1

[0031] like Figures 1 to 7 As shown, a preferred embodiment of the present invention provides an oxygen wound therapy device, comprising a base 1, a lifting device 2, an oxygen generator 3, a mounting frame 4, and an oxygen blowing hood 5. The lifting device 2 is mounted on the base 1, and the mounting frame 4 is connected to the lifting device 2. The lifting device 2 drives the mounting frame 4 to move up and down. The oxygen blowing hood 5 is movably connected to the mounting frame 4 along its length. The oxygen generator 3 is mounted on the lifting device 2 and connected to the oxygen blowing hood 5 via a connecting pipe 9. This embodiment, by setting the lifting device 2 on the base 1, mounting the oxygen generator 3 and the mounting frame 4 on the lifting device 2, and movably connecting the oxygen blowing hood 5 to the mounting frame 4, achieves high overall integrity and facilitates the overall movement of the therapy device. In use, the therapy device is placed next to the patient, and the height of the oxygen blowing hood 5 can be adjusted using the lifting device 2. Furthermore, the oxygen blowing hood 5 is movable, allowing adjustment of its position on the mounting frame 4. Therefore, the oxygen mask 5 can be adjusted to be aimed at the patient's wound. The oxygen mask 5 is supported by the mounting frame 4 and the lifting device 2, eliminating the need for nurses to hold it, making it convenient to use. Furthermore, the height and position of the oxygen mask 5 are adjustable, maintaining a certain distance between it and the wound, avoiding contact and pressure on the patient, ensuring smooth and hygienic airflow from the oxygen mask 5, and preventing secondary damage to the wound. Therefore, the treatment device in this embodiment is convenient, safe, and comfortable to use.

[0032] Example 2

[0033] The difference between this embodiment and Embodiment 1 is that, based on Embodiment 1, the treatment device in this embodiment also includes a winding device 6.

[0034] The oxygen wound therapy device in this embodiment also includes a winding device 6, which includes a winding frame 601, a winding motor 602, a winding tube 603, and a winding shaft 604. The winding frame 601 is connected to the lifting device 2, the winding motor 602 is mounted on the winding frame 601, and the winding shaft 604 is rotatably connected to the winding frame 601. The winding motor 602 is connected to the winding shaft 604, and the winding motor 602 drives the winding shaft 604 to rotate. One end of the winding tube 603 is connected to the connecting pipe 9, and the other end of the winding tube 603 is connected to the oxygen blowing hood 5. The winding tube 603 is wound around the winding shaft 604. The oxygen blowing hood 5 is raised and lowered by the lifting device 2 and moved on the mounting frame 4. Therefore, during the adjustment of the position of the oxygen blowing hood 5, the pipe connecting the oxygen blowing hood 5 and the oxygen generating device 3 needs to be extended or shortened. If the winding device 6 is not used for winding, the pipe is easily trampled. In this embodiment, the winding tube 603 is connected to the connecting pipe 9. The winding tube 603 can be wound up by the winding motor 602 driving the winding shaft 604 to rotate, making the pipe easier to manage.

[0035] Furthermore, the winding device 6 in this embodiment also includes a conversion sleeve 605, which has an open end and a hollow interior. The winding shaft 604 has an open end and a hollow interior, and its side has an air outlet 6041 communicating with its interior. The conversion sleeve 605 is connected to the winding frame 601. One end of the connecting pipe 9 is connected to the oxygen generator 3, and the other end of the connecting pipe 9 is connected to one end of the conversion sleeve 605. The open end of the winding shaft 604 is sealed and rotatably connected to the other end of the conversion sleeve 605. One end of the winding tube 603 is connected to the air outlet 6041, and the other end of the winding tube 603 is connected to the oxygen blowing hood 5. In this embodiment, the connecting pipe 9 is connected to one end of the conversion sleeve 605, the winding shaft 604 is connected to the other end of the conversion sleeve 605, and the winding tube 603 is connected to the winding shaft 604. In operation, the oxygen generated by the oxygen generator 3 enters the conversion sleeve 605 through the connecting pipe 9, then enters the take-up shaft 604, and finally reaches the oxygen blowing hood 5 through the take-up tube 603. Since the take-up shaft 604 needs to rotate to retract or release the take-up tube 603, if the take-up tube 603 were directly connected to the oxygen generator 3, the connecting pipe 9 of the oxygen generator 3 could easily detach during the winding process. This embodiment uses the conversion sleeve 605 to keep the connecting pipe 9 of the oxygen generator 3 stationary during the operation of the take-up device 6, and the connection between the take-up shaft 604 and the take-up tube 603 ensures oxygen flow, preventing the pipe from detaching.

[0036] In addition, the winding frame 601 of this embodiment includes a support plate 6011 and a first support plate 6012 and a second support plate 6013 connected to the support plate 6011. One end of the support plate 6011 is connected to the lifting device 2. The first support plate 6012 and the second support plate 6013 are arranged in parallel and spaced apart. The winding shaft 604 is located between the first support plate 6012 and the second support plate 6013. Both the first support plate 6012 and the second support plate 6013 are provided with mounting holes 6014. The winding motor 602 is mounted on the first support plate 6012. One end of the winding shaft 604 passes through the mounting hole 6014 of the first support plate 6012 and is connected to the winding motor 602. The conversion sleeve 605 is connected to the second support plate 6013, and the conversion sleeve 605 is coaxial with the mounting hole 6014 of the second support plate 6013. One open end of the winding shaft 604 is connected to the mounting hole 6014 of the second support plate 6013 through a sealed bearing. In this embodiment, the support plate 6011 also includes a through hole 6015. The first support plate 6012, the second support plate 6013, the winding motor 602, and the winding shaft 604 are located below the support plate 6011. The winding tube 603 passes through the through hole 6015 and is connected to the oxygen blowing hood 5. Placing the winding motor 602, the winding shaft 604, and the conversion sleeve 605 below the support plate 6011 provides protection.

The positioning posts 703 are located above the placement plate 701, and the positioning ring 702 is located above the positioning posts 703. When the oxygen generator 3 is placed, it is positioned above the placement plate 701. In this embodiment, the top surface of the placement plate 701 is provided with a placement groove 707. The shape and size of the placement groove 707 are adapted to the oxygen generator 3. The placement groove 707 is used for positioning and limiting the oxygen generator 3. In this embodiment, the placement plate 701, positioning posts 703, and positioning ring 702 form an open basket structure, which facilitates the installation and removal of the oxygen generator 3.

[0041] In addition, the lifting device 2 in this embodiment is an electric telescopic pole. The lifting device 2 includes a main pole 201 and a secondary pole 202. The secondary pole 202 is inserted into the main pole 201. The oxygen generator 3 is installed on the main pole 201. The mounting bracket 4 is connected to the extended end of the secondary pole 202. The placement plate 701 is connected to the main pole 201. The use of an electric telescopic pole provides a certain height for the treatment, allows it to be placed on the ground for use, and is convenient to operate when powered on.

[0042] The placement rack 7 in this embodiment also includes two positioning blocks 704, two positioning screws 705, and two positioning nuts 706. One end of the placement plate 701 is provided with an arc-shaped groove 708. The two positioning screws 705 are connected to the placement plate 701 and are arranged in parallel. The two positioning screws 705 are located on both sides of the arc-shaped groove 708. The positioning blocks 704 are provided with positioning holes. The positioning blocks 704 are sleeved on the positioning screws 705 through the positioning holes. The positioning nuts 706 are connected to the positioning screws 705. The positioning blocks 704 are located between the positioning nuts 706 and the placement plate 701. The main rod 201 can be in the arc-shaped groove 708. The two positioning blocks 704 are clamped on the main rod 201. The positioning screws 705 are straight lines tangent to the arc-shaped groove 708. By rotating the positioning nuts 706, the positioning blocks 704 can move along the positioning screws 705. During the movement, the positioning blocks 704 are in close contact with the main rod 201 to achieve clamping. The positioning block 704, positioning screw 705 and positioning nut 706 of this embodiment facilitate the installation and disassembly of the placement frame 7 and the main rod 201, thereby facilitating the adjustment of the height and direction of the oxygen generator 3.

[0043] The other structures in this embodiment are the same as in Embodiment 2, and will not be described again here.

[0044] Example 4

[0045] The difference between this embodiment and embodiment three is that, based on embodiment three, this embodiment provides further explanation of the mounting bracket 4 and the oxygen blowing hood 5.

[0046] In this embodiment, the mounting frame 4 includes a mounting plate 401 and a moving motor 402. The moving motor 402 is mounted on the mounting plate 401 and is a linear motor. The oxygen blowing hood 5 is connected to a sliding member of the moving motor 402. The moving motor 402 includes a fixed member and a sliding member. The sliding member is slidably connected to the fixed member. When the moving motor 402 is working, the sliding member slides along the fixed member. When the moving motor 402 is working, its sliding member slides along its sliding axis, thereby driving the oxygen blowing hood 5 connected to the sliding member to move.

[0047] In this embodiment, the mounting plate 401 has a first mounting portion 403 and two second mounting portions 404. The two second mounting portions 404 are vertically connected to both ends of the first mounting portion 403, making the mounting plate 401 have a "U"-shaped structure. The second mounting portions 404 have receiving holes 405 extending through both sides of them. The receiving holes 405 extend along the length of the second mounting portions 404. The moving motor 402 is located in the mounting hole 6014, and the top of the oxygen blowing hood 5 is located between the two second mounting portions 404. In this embodiment, the first mounting portion 403 also has a mounting sleeve 406. The top end of the auxiliary rod 202 is inserted into the mounting sleeve 406 to realize the connection between the mounting frame 4 and the lifting device 2.

[0048] The oxygen blowing hood 5 in this embodiment is provided with an oxygen inlet 501 and multiple oxygen outlets 502. The oxygen inlet 501 is used for oxygen generated by the oxygen generator 3 to enter, and the oxygen outlets 502 are connected to the oxygen inlet 501. The oxygen inlet 501 is connected to the take-up tube 603 to supply oxygen into the oxygen blowing hood 5, and then the oxygen is blown onto the patient's wound through the oxygen outlets 502. The oxygen blowing hood 5 in this embodiment has a rectangular structure.

[0049] Furthermore, the base 1 in this embodiment is equipped with casters 8 for easy movement of the therapeutic device. The casters 8 are also braked swivel casters, allowing for positioning after the device has been moved into place.

The height of the mounting frame 4 is adjusted through the lifting device 2, and then the oxygen blowing mask 5 is moved through the moving motor 402, adjusting its position so that it is above the wound. The winding tube 603 is then tightened through the winding device 6. The oxygen generator 3 is turned on, and oxygen enters the conversion sleeve 605 through the connecting tube 9, then enters the hollow winding shaft 604, and then enters the oxygen blowing mask 5 through the winding tube 603, finally being blown out from the oxygen blowing mask 5 to treat the patient's wound. In addition, this utility model can also be used as an oxygen concentrator. In this case, the connecting tube 9 is disconnected from the oxygen outlet of the oxygen generator 3, and the tube of the oxygen mask is inserted to provide oxygen for the patient's breathing.

[0051] In summary, this utility model embodiment provides an oxygen wound therapy device. It features a lifting device 2 mounted on a base 1; an oxygen generator 3 and a mounting frame 4 are both mounted on the lifting device 2, and an oxygen blowing mask 5 is movably connected to the mounting frame 4.
