[0037] The present application is made based on the discovery and understanding of the inventor on the following facts and problems:

[0038] The skin oxygen therapy mainly performs oxygen therapy on the skin around the anus, the buttocks and the perineum of the patient. In the process of skin oxygen therapy, the oxygen content of the skin tissue of the patient is increased by discharging oxygen to the skin of the patient, the dryness degree of the skin of the patient is improved, the moist damage to the skin of the patient is avoided, the skin healing and regeneration is promoted, and the metabolism of the skin of the patient is promoted, and the skin of the patient is recovered to health.

[0039] In the prior art, the skin oxygen therapy process needs to use a leg support and an oxygen supply device. The patient can put two legs on two leg supports of the leg support respectively. Since there is a certain distance between the two leg supports, when the patient puts two legs on the two leg supports respectively, the patient opens two legs, exposes the skin around the anus, the buttocks and the perineum, at this time, the oxygen supply device is arranged between the two legs of the patient, and the oxygen supply device can supply oxygen to the skin around the anus, the buttocks and the perineum of the patient.

[0040] In the skin oxygen therapy process, the leg support cannot be adaptively adjusted according to different needs of different patients, and the body position of the patient cannot be adjusted in time according to the actual situation of the patient during use, so the practicability is poor, the use experience of the patient is poor, and the position and stability of the oxygen supply device cannot be guaranteed, the stability of oxygen supply during the oxygen therapy process cannot be guaranteed, and the oxygen therapy effect is affected.

[0041] Therefore, the skin oxygen therapy device 100 is designed to integrate the leg support 3 and the oxygen supply assembly 4. Thus, the relative position of the leg support 3 and the oxygen supply assembly 4 is fixed, the setting stability of the oxygen supply assembly 4 is guaranteed, the stability of oxygen supply during the oxygen therapy process is ensured, the oxygen therapy effect is ensured, and after the two legs of the patient are put on the first support 31 and the second support 32 of the leg support 3 respectively, the direction and height of the legs of the patient can be adjusted according to the needs of the patient. Thus, the skin around the anus, the buttocks and the perineum of patients in different situations can be fully exposed, the skin oxygen therapy effect is ensured, and the difficulty of the medical staff in the process of skin oxygen therapy of the patient is reduced.

[0042] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout.

In addition, the features limited by "first" and "second" can be explicitly or implicitly included one or more features. In the description of the utility model, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0044] In the description of the utility model, it should be explained that, unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be directly connected, or indirectly connected through an intermediate medium, or it can be connected inside two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0045] The skin oxygen therapy device 100 according to the embodiment of the utility model is described below with reference to the drawings.

[0046] As shown in Figures 1-6 The skin oxygen therapy device 100 according to the embodiment of the utility model comprises a base 1, a first support 2, a leg support 3 and an oxygen supply assembly 4.

[0047] The first support 2 and the leg support 3 are both arranged on the base 1, wherein the first support 2 is fixedly arranged on the base 1, the oxygen supply assembly 4 comprises an air outlet cover 41, the first support 2 is used to support the air outlet cover 41 of the oxygen supply assembly 4, the leg support 3 comprises a first support 31 and a second support 32 arranged on both sides of the first support 2 respectively, the first support 31 and the second support 32 can support two legs of a patient respectively, since there is a certain distance between the first support 31 and the second support 32, when the patient's legs are respectively placed on the first support 31 and the second support 32, the patient's legs are opened, the skin of the perianal, buttock and perineum of the patient is exposed, the air outlet cover 41 is arranged on the first support 2 and between the first support 31 and the second support 32, and can supply oxygen to the skin of the perianal, buttock and perineum of the patient.

[0048] Since the base 1 integrates the leg cradle 3 and the air outlet cover 41, the relative positions of the first cradle 31 and the second cradle 32 and the air outlet cover 41 are fixed, the oxygen supply assembly 4 is prevented from supplying oxygen to the oxygen therapy skin area outside, and the stability of the leg cradle 3 and the air outlet cover 41 is ensured, thereby ensuring the stability of oxygen supply during oxygen therapy and ensuring the oxygen therapy effect.

[0049] Further, after the patient's legs are placed on the first cradle 31 and the second cradle 32 of the leg cradle 3 respectively, some patients need to adjust the orientation and height of the legs, that is, the height and angle of the first cradle 31 and the second cradle 32 need to be controlled. The leg cradle 3 is adjustably arranged on the base 1 and rotatably arranged on the first support 2, that is, the leg cradle 3 can adjust the orientation and height of the patient's legs according to the patient's needs. Therefore, it is ensured that patients in different situations can fully expose the perianal, buttock and perineal skin, ensure the skin oxygen therapy effect, and reduce the difficulty of the medical staff in the process of skin oxygen therapy.

[0050] The air outlet cover 41 defines an air outlet 411, and the air outlet cover 41 is arranged on the first support 2 in a manner that the pitch angle of the air outlet 411 is adjustable. By adjusting the pitch angle of the air outlet 411 of the air outlet cover 41, the oxygen supply height of the air outlet cover 41 can be controlled. For example, the oxygen supply height to the perianal skin should be lower than the oxygen supply height to the perineal skin, that is, the pitch angle of the air outlet 411 when supplying oxygen to the perianal skin is smaller than the pitch angle of the air outlet 411 when supplying oxygen to the perineal skin. When the oxygen supply range changes, the pitch angle of the air outlet cover 41 can be controlled conveniently.

[0051] According to the skin oxygen therapy device 100, the air outlet cover 41 and the leg cradle 3 are integrated on the base 1, the stability of oxygen supply is ensured, and the orientation and height of the patient's legs can be adjusted according to the patient's needs. Therefore, it is ensured that patients in different situations can fully expose the part of the skin that needs to be oxygenated, and the skin oxygen therapy effect is ensured.

[0052] As shown in Figure 1 and Figure 2 , in order to realize the limitation of the leg cradle 3, ensure that the leg cradle 3 can rotate around the first support 2 and ensure that the leg cradle 3 is adjustable in height, the leg cradle 3 comprises a sleeve 33, the first support 2 comprises a guide rod 21 extending in the vertical direction, and the sleeve 33 is sleeved on the guide rod 21. Therefore, the sleeve 33 can rotate relative to the guide rod 21, and the first cradle 31 and the second cradle 32 connected with the sleeve 33 can also rotate around the guide rod 21 of the first support 2.

[0053] The sleeve 33 can move up and down along the guide rod 21 to avoid the influence of the arrangement of the first support 2 on the height adjustment of the leg bracket 3.

[0054] The first support 2 further comprises a connecting portion 22 fixedly arranged above the guide rod 21, and the air outlet cover 41 is arranged on the first support 2 in a pitch angle adjustable manner through the connecting portion 22. The connecting portion 22 comprises a first bifurcated portion 221 and a second bifurcated portion, the first bifurcated portion 221 and the second bifurcated portion are arranged on the two sides of the first direction of the air outlet cover 41 respectively, and are connected with the top of the guide rod 21 at the same time. The air outlet cover 41 is rotatably connected with the first bifurcated portion 221 and the second bifurcated portion at the same time, and the rotation shafts extend along the first direction.

[0055] Referring to Figure 1 and Figure 2 , the first bracket 31 and the second bracket 32 are connected with the sleeve 33, so that the first bracket 31 and the second bracket 32 can move synchronously with the sleeve 33. Since the first bracket 31, the second bracket 32 and the sleeve 33 are connected to form an integral whole, the overall height of the leg bracket 3 can be adjusted by adjusting the height of one of the first bracket 31 or the second bracket 32.

[0056] As shown in Figure 2 and Figure 5 , the leg bracket 3 is provided with a locking structure 34, which is used to limit the leg bracket 3 to a position after the leg bracket 3 is rotated to the position relative to the first support 2, so that the relative position of the leg bracket 3 in the circumferential direction is fixed. After the position of the leg bracket 3 is fixed, the posture of the patient's leg is fixed, and the oxygen delivery assembly 4 can stably deliver oxygen to the skin around the anus, the buttocks and the perineum for oxygen therapy.

[0057] In some embodiments, the locking structure 34 is arranged on the sleeve 33, and the base 1 is provided with a plurality of locking matching structures arranged around the guide rod 21. The locking structure 34 is selectively matched with the locking matching structures to lock and fix the rotating position of the leg bracket 3. When the locking structure 34 is matched with any one of the plurality of locking matching structures arranged around the guide rod 21, the relative position of the sleeve 33 and the base 1 in the circumferential direction is fixed, the sleeve 33 cannot rotate relative to the guide rod 21, and thus the entire leg bracket 3 cannot rotate relative to the guide rod 21. The relative position of the leg bracket 3 and the base 1 in the circumferential direction is fixed, the posture of the patient's leg is fixed, and the oxygen delivery assembly 4 can stably deliver oxygen to the skin around the anus, the buttocks and the perineum for oxygen therapy.

[0058] And the locking structure 34 is arranged on the sleeve 33, the locking structure 34 and the locking matching structure matched with the locking structure 34 are closer to the rotation center of the leg bracket 3, avoiding that the arrangement of the locking structure 34 and the locking matching structure occupies a larger space above the base 1, and the locking structure 34 and the locking matching structure are closer to the rotation center, reducing the number of opening and positioning costs in the opening process of the locking matching structure.

[0059] With reference to Figure 4 The locking structure 34 comprises a connecting plate 331 and a limiting pin 342, the connecting plate 331 extends along the horizontal direction and is connected with the sleeve 33 to provide a position for the opening of the through hole 341, the connecting plate 331 is provided with the through hole 341 extending along the vertical direction, the limiting pin 342 can pass through the through hole 341 extending along the vertical direction and move along the vertical direction in the through hole 341, the limiting pin 342 comprises a limiting part 3421 and a locking part 3422, the locking part 3422 passes through the through hole 341 and can move along the vertical direction under the guidance of the through hole 341, the limiting part 3421 is arranged above the connecting plate 331 and extends along the horizontal direction, and the limiting part 3421 is connected with the upper end of the locking part 3422. The arrangement of the limiting part 3421 can avoid the locking part 3422 from being separated from the connecting plate 331 and the through hole 341 during the process of passing through the through hole 341 from top to bottom, and ensures that the limiting pin 342 is always limited by the through hole 341.

[0060] The locking matching structure comprises a matching hole 111, when the leg bracket 3 is unlocked, the limiting pin 342 only matches with the through hole 341 opened on the connecting plate 331, at this time, the leg bracket 3 is limited and connected with the base 1 only through the matching relationship between the sleeve 33 and the guide rod 21, and the leg bracket 3 can rotate relative to the guide rod 21, when the leg bracket 3 is locked, the limiting pin 342 matches with the through hole 341 and any one of the plurality of matching holes 111 at the same time, at this time, the leg bracket 3 has two matching and connecting positions of the matching of the sleeve 33 and the guide rod 21 and the matching of the limiting pin 342 and the matching hole 111, realizes two-point limiting, fixes the relative position of the leg bracket 3 and the base 1 in the horizontal direction, and realizes the locking and limiting of the leg bracket 3 in the circumferential direction.

[0061] Further, the matching of the limiting pin 342 and the matching hole 111 will not limit the leg bracket 3 in the vertical direction, and the leg bracket 3 can move along the vertical direction to adjust the height, avoiding that the locking of the leg bracket 3 in the circumferential direction by the locking structure 34 affects the height adjustment of the leg bracket 3, so that the height adjustment and the angle adjustment of the leg bracket 3 can be carried out respectively, which is beneficial to simplify the control of the skin oxygen therapy device 100.

[0062] With reference to Figure 1 And Figure 2In order to ensure the stability of the leg bracket 3, the leg bracket 3 further comprises a second support 35 and a third support 36, the second support 35 and the third support 36 are movably arranged above the base 1, the first bracket 31 is movably supported above the second support 35 in the vertical direction, and the second bracket 32 is movably supported above the third support 36 in the vertical direction.

[0063] The first bracket 31 and the second bracket 32 can move together with the sleeve 33 in the vertical direction, and the first bracket 31 and the second bracket 32 are arranged apart from the base 1. In order to ensure the stability of the arrangement of the first bracket 31 and the second bracket 32, and to ensure that the first bracket 31 and the second bracket 32 can be limited to a certain height, a second support 35 is arranged between the first bracket 31 and the base 1, and a third support 36 is arranged between the second bracket 32 and the base 1. The second support 35 and the third support 36 can support the first bracket 31 and the second bracket 32 below the first bracket 31 and the second bracket 32, respectively, and can withstand the weight of the legs above the first bracket 31 and the second bracket 32. Avoiding the stress concentration caused by the different directions of the supporting force of the first bracket 31 and the second bracket 32 and the direction of gravity, and ensuring the stability of the leg bracket 3 supporting the legs.

[0064] The second support 35 and the third support 36 can rotate with the first bracket 31 and the second bracket 32 around the first support 2. Since the second support 35 and the third support 36 are arranged above the base 1, the rotation of the second support 35 and the third support 36 relative to the base 1 will cause the friction of the contact part of the second support 35 and the third support 36 with the base 1, resulting in noise and damage to the structure. Therefore, the contact part of the second support 35 and the third support 36 with the base 1 is provided with a pulley. During the rotation of the second support 35 and the third support 36 relative to the base 1, the contact part of the second support 35 and the third support 36 with the base 1 changes from sliding friction to rolling friction, which reduces the friction between the second support 35 and the third support 36 and the base 1 without affecting the supporting force of the second support 35 and the third support 36 with the base 1 in the vertical direction.

[0065] In order to ensure the stability of the second support 35 and the third support 36, the second support 35 and the third support 36 have two support points on both sides in the length direction, which cooperate with the base 1. The two support points are each provided with a pulley. Specifically, the second support 35 is provided with a first pulley 352 and a second pulley 351, and the third support 36 is provided with a third pulley 362 and a fourth pulley 361.

[0066] In the process of rotating the second support 35 to the center of the third support 36, the first pulley 352 and the second pulley 351 arranged on the second support 35 are matched with two slide grooves arranged on the base 1, the third pulley 362 and the fourth pulley 361 arranged on the third support 36 are matched with two slide grooves arranged on the base 1, the slide grooves can limit and guide the pulleys in the process of moving, ensure the stability of the first support 2 and the second support 35 in the process of moving, and the slide grooves can also position the second support 35 and the third support 36 in the process of installing the second support 35 and the third support 36, so as to ensure the accuracy of installation.

[0067] In order to simplify the structure of the base 1, the first pulley 352 and the third pulley 362 are arranged at the same distance from the first support 2 and are matched with the first slide groove 112 arranged on the base 1, and the second pulley 351 and the fourth pulley 361 are arranged at the same distance from the first support 2 and are matched with the second slide groove 121 arranged on the base 1, so that only two slide grooves need to be arranged on the base 1 to realize the limiting and guiding of the second support 35 and the third support 36, the structure of the base 1 is simplified, and the production cost is reduced.

[0068] In addition, the first pulley 352 and the third pulley 362 are arranged at the same distance from the first support 2, the second pulley 351 and the fourth pulley 361 are arranged at the same distance from the first support 2, the structures of the second support 35 and the third support 36 are similar, and the same production method can be used for production, so as to reduce the structure design and mold opening cost of the skin oxygen therapy device 100.

[0069] In some embodiments, the base 1 can be formed as a whole complete bottom plate to reduce the gravity center of the whole device by using its own gravity, so as to ensure the stability of the whole skin oxygen therapy device 100.

[0070] In other embodiments, referring to Figure 1 and Figure 2 , the base 1 is composed of a frame structure to increase the contact area between the base 1 and the bed body while reducing the weight of the whole device, so as to ensure the stability of the whole skin oxygen therapy device 100.

[0071] Specifically, the base 1 is composed of an inner frame 11, an outer frame 12, and a radiation rib 13 connected between the inner frame 11 and the outer frame 12. As shown in Figure 1 and Figure 2 , the first slide groove 112 is arranged on the inner frame 11 of the base 1, the second slide groove 121 is arranged on the outer frame 12 of the base 1, and a plurality of spaced radiation ribs 13 are arranged between the inner frame 11 and the outer frame 12, which can connect the inner frame 11 and the outer frame 12 into one body to ensure the structural strength of the base 1.

[0072] The height of the leg support 3 is adjustable. Since the bottom of the leg support 3 is always in contact with the base 1, the height adjustment of the leg support 3 needs to be achieved by a lifting assembly 37 with variable height between the first bracket 31 and the second bracket 35; and / or between the second bracket 32 and the third bracket 36; and / or between the sleeve 33, the first bracket 31 and the second bracket 32 as a whole and the base 1. The change in height of the lifting assembly 37 changes the distance between the sleeve 33, the first bracket 31 and the second bracket 32 as a whole and the base 1, thereby achieving the purpose of adjusting the height of the leg support 3 to support the legs.

[0073] In some embodiments, the lifting assembly 37 can include a lifting rod, a driving cylinder, a combination of a fixed structure and a plurality of height-directionally arranged cooperating structures, etc., as long as the purpose of height adjustment is achieved, which is not limited here.

[0074] As shown in Figure 4 The lifting assembly 37 includes a driving member 371, a transmission member 372 and a lifting plate 373. The driving member 371 includes a first bevel gear 3711 extending in the horizontal direction, and the driving member 371 is rotationally connected with the second bracket 35 or the third bracket 36. At least part of the structure of the driving member 371 extends to the outside of the second bracket 35 or the third bracket 36, so as to facilitate the medical staff to manually drive the driving member 371 to rotate. Alternatively, the driving member 371 can be driven by a driving motor, and the driving member 371 rotates about a rotating shaft extending in the horizontal direction, and the height position relationship between the driving member 371 and the second bracket 35 or the third bracket 36 remains unchanged.

Thus, when the first bevel gear 3711 of the driving member 371 rotates under the action of external driving or motor driving, it can drive the second bevel gear 3721 meshing with the first bevel gear 3711 to rotate. Since the second bevel gear 3721 is fixedly connected with the lead screw 3722, the rotation of the second bevel gear 3721 drives the rotation of the lead screw 3722.

[0076] The lifting plate 373 is fixedly connected with the first bracket 31 and / or the second bracket 32. The lifting plate 373 is provided with a reserved position of a threaded hole 3731, and the contact area between the lifting assembly 37 and the first bracket 31 and the second bracket 32 is increased, so as to avoid excessive local stress and damage to the structure of the lifting assembly 37, thereby affecting the normal lifting of the leg support 3.

[0077] The lifting plate 373 is provided with a threaded hole 3731, and the threaded hole 3731 is matched with the lead screw 3722. When the lead screw 3722 rotates under the driving of the driving member 371, the lifting plate 373 provided with the threaded hole 3731 is limited to move in the horizontal direction by the first bracket 31 or the second bracket 32, so that the lead screw 3722 rotates in the threaded hole 3731 and drives the lifting plate 373 to rise or fall, thereby driving the first bracket 31 or the second bracket 32 fixedly connected with the lifting plate 373 to rise or fall, and further driving the whole lifting formed by the sleeve 33, the first bracket 31 and the second bracket 32 to rise or fall.

[0078] In some embodiments, a plurality of limiting guide structures are further arranged between the second bracket 35 or the third bracket 36 and the lifting plate 373, and the lifting plate 373 is movably arranged on the second bracket 35 in the vertical direction through the limiting guide structures.

The valve 44 communicates with the timing device 43 and the controller 45. The controller 45 controls the valve 44 to close according to the time set by the timing device 43.

[0085] In some embodiments, the controller 45 also communicates with the controllable low-temperature device 42 to control the opening and closing of the controllable low-temperature device 42, thereby controlling the oxygen supply temperature of the oxygen supply assembly 4.

[0086] As shown in Figure 1 and Figure 2 , the upper surfaces of the first bracket 31 and the second bracket 32 are formed in a downwardly concave arc shape, so that the shape of the first bracket 31 and the second bracket 32 is more ergonomic, and the patient's legs are more comfortable when placed on the first bracket 31 and the second bracket 32.

[0087] In some embodiments, the first bracket 31 and the second bracket 32 are covered with a leather cover that isolates the human skin from the first bracket 31 or the second bracket 32, reduces the local skin pressure when the legs are placed on the first bracket 31 or the second bracket 32, has good ventilation effect, avoids pressure sores, and improves the comfort of the patient during oxygen therapy. During use, the first bracket 31 and the second bracket 32 can also be externally provided with a disposable protective sleeve to avoid cross-infection between patients.

[0088] In some embodiments, the first bracket 31 and the second bracket 32 are detachably provided with a protective pad above, which can isolate the human skin from the first bracket 31 or the second bracket 32, reduce the local skin pressure when the legs are placed on the first bracket 31 or the second bracket 32, avoid pressure sores, and improve the comfort of the patient during oxygen therapy.

[0089] The protective pad can be a gel pad, which is soft in texture, can achieve sufficient buffering between the first bracket 31 or the second bracket 32 and the skin of the patient, avoid the formation of pressure sores, and is cool, breathable, sweat-absorbing, moisture-removing, and comfortable for the patient during oxygen therapy, and the gel pad is more convenient to clean and disinfect, which is conducive to the reuse of the skin oxygen therapy device 100.
