Description

Technical Field

[0001] The invention belongs to the technical field of nursing, in particular to self-temperature regulating and pressure sore preventing nursing pants. Background Art

[0002] Pressure sores, also known as pressure ulcers or bedsores, are caused by long-term pressure on local tissues, resulting in persistent ischemia, hypoxia, and malnutrition, leading to tissue ulceration and necrosis. Skin pressure sores are a common problem in rehabilitation treatment and nursing. Pressure factors include vertical pressure, friction, and shear force. Nursing pants are a type of adult care product, made of PE film, non-woven fabrics, fluff pulp, polymers and other materials, and are suitable for use by people after surgery in hospitals, paralyzed patients, and people who cannot take care of themselves. With the accelerated pace of life, the demand for adult nursing pads continues to expand. Bedridden women, the elderly, women during menstruation, and even long-distance travelers all need to use adult nursing pads. The present invention is aimed at nursing pants for paralyzed patients.

[0003] At present, paralyzed patients are unable to move their bodies independently and are bedridden for a long time. The weight of the body when lying flat for a long time will put pressure on the buttocks, and the buttocks will be in a compressed state for a long time, which will reduce the blood circulation in the buttocks, thereby causing blood arrhythmia and hypoxia in the buttocks. Over a long period of time, the buttocks tissue of the paralyzed patients will ulcerate and necrotize, thereby forming pressure sores. At present, paralyzed patients will use nursing pants while lying in bed to reduce the cleaning of excrement and reduce the number of times paralyzed patients are moved. However, the current nursing pants have poor air permeability and do not have the function of preventing pressure sores, thereby reducing the air permeability of the buttocks of paralyzed patients and increasing the pressure sores on the buttocks. Therefore, the present invention provides self-temperature regulating and anti-pressure sore nursing pants. Summary of the Invention

[0005] In order to solve the problems raised in the above-mentioned background technology, the present invention provides self-temperature regulating anti-pressure ulcer nursing pants, which starts a controller controlled by an air injection pump and injects air into the interior of the air cushion through an air inlet pipe. Since the interior of the air cushion is in a sealed state, the gas inside the air cushion gradually increases and expands, which will squeeze the patient's buttocks and push out the pressure pad at the same time. The patient's buttocks are then squeezed and stimulated by the pressure pad and the protrusion respectively, and the pressure pad is pushed out to stimulate the patient's buttocks. In this way, the gas repeatedly enters the interior of the air cushion in turn, and pushes out the pressure pad in turn, stimulating the patient's buttocks, thereby improving the blood circulation of the patient's buttocks.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention achieves the purpose of blood circulation in the patient's buttocks by providing a pressure pad, a connecting valve and a connecting rope. The controller is started by controlling the air injection pump, and air is injected into the interior of the air cushion through the air inlet pipe. Since the interior of the air cushion is in a sealed state, the gas inside the air cushion gradually increases and expands, which will squeeze the patient's buttocks and push the pressure pad out at the same time. The patient's buttocks are squeezed and stimulated by the pressure pad and the convex block respectively. When the pressure pad is pushed out again, the connecting block stretches the connecting rope respectively, and one end of the connecting rope will drive the connecting valve, and the limit plate will limit the connecting valve, so that the interior of the air cushion is sealed, and the controller continuously The air inside the air cushion is filled with air, and the air inside the air cushion gradually increases. When the air cushion is in a saturated state, the gas will push open the middle part of the connecting valve, and the gas inside the air cushion enters the next air cushion through the connecting valve. The gas inside the first air cushion will decrease, and at the same time the connecting valve will be pushed open, and the pressure pads will be pulled into the air cushions through the connecting ropes. At the same time, the gas inside the next air cushion will push the pressure pad out to stimulate the patient's buttocks. In this way, the gas will repeatedly enter the air cushions in turn and push the pressure pads out in turn, stimulating the patient's buttocks, thereby improving the blood circulation in the patient's buttocks and achieving the effect of blood circulation in the patient's buttocks.

[0020] The present invention achieves the purpose of cooling the nursing pants by providing a circulation pipe, an electromagnetic pressure relief valve and an exhaust pipe. Gas is injected into the interior of the air cushion through a controller. When the gas enters the interior of the last air cushion, it enters the interior of the controller through the circulation pipe for circulation, thereby ensuring the temperature of the gas inside the air cushion. At the same time, the temperature of the patient's buttocks is monitored in real time by a temperature sensor. If the temperature is greater than a set value, the electromagnetic pressure relief valve will automatically open, so that the gas inside the air cushion is discharged through the exhaust pipe. Then, gas is drawn from the outside through the controller and injected into the interior of the air cushion. The gas inside the air cushion exchanges heat with the patient's buttocks, thereby reducing the temperature of the patient's buttocks and making the patient more comfortable, thereby achieving the effect of cooling the nursing pants.

[0021] The present invention achieves the purpose of cushioning the patient's buttocks by providing an air cushion, a support plate and a storage pocket. By putting the outer layer on the patient's upper body, the storage pocket will come into contact with the patient's buttocks. At the same time, the air cushion and the support plate are made of rubber material, and the air cushion will come into contact with the patient's buttocks. When the patient lies down flat, the air cushion will be located at the bottom of the patient's buttocks, supporting the patient's buttocks through the air cushion, thereby improving the patient's comfort. At the same time, the gaps between the air cushions will form ventilation, thereby improving the air permeability of the nursing pants, thereby effectively reducing the formation of pressure sores on the patient's buttocks, thereby achieving the effect of cushioning the patient's buttocks.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, the present invention provides self-temperature regulating anti-pressure sore nursing pants, including an outer layer 1 and a controller 9, an air injection pump 8 is fixedly installed on the front of the controller 9, a protective layer 4 is fixedly installed on the inner side of the outer layer 1, an inner layer 7 is fixedly installed on the inner side of the protective layer 4, fixing components 2 are fixedly installed on the left and right sides of the outer layer 1, a placement component 3 is fixedly installed on the back side of the inner wall of the inner layer 7, an air injection component 6 is fixedly clamped on the inner side of the placement component 3, a pressure application component 10 is fixedly installed on the front side of the air injection component 6, and an excretion port 5 is opened on the front side of the outer layer 1;

[0033] The fixing assembly 2 includes a fixing rope 201 , which is fixedly mounted on the left and right sides of the outer layer 1 . The left and right sides of the outer layer 1 are respectively fixedly mounted with first Velcro hook surfaces 202 , and the back side of the fixing rope 201 is fixedly mounted with a first Velcro fleece surface 203 .

[0034] The above scheme is adopted: when a paralyzed patient needs to use nursing pants while lying in bed, the fixing rope 201 is first removed, the outer layer 1 is unfolded, and the fixing plate 601 is placed inside the storage pocket 301, so that the second Velcro surface 302 contacts the second Velcro hook surface 303, and the fixing plate 601 inside the storage pocket 301 is fixed. At the same time, the air inlet pipe 602 and the circulation pipe 603 will pass through one side of the outer layer 1 and dock with the top of the controller 9. After the gas injection component 6 and the outer layer 1 are installed, the outer layer 1 is put on the patient's body, and the front and rear ends of the outer layer 1 are connected by the fixing rope 201. At the same time, the first Velcro surface 203 contacts the first Velcro hook surface 202, so that the outer layer 1 can be fixed to the patient's body. The fixing component 2 can meet the needs of paralyzed patients of different body shapes.

[0035] like Figure 8 As shown, the inner layer 7 is made of pure cotton material, the storage pocket 301 is made of the same material as the inner layer 7, the protective layer 4 is made of thickened polyurethane sponge material, and the outer layer 1 is made of intelligent fiber phase change material.

[0036] Adopting the above solution: by putting the outer layer 1 on the patient's body, it fits the body better, has high adaptability, and is applicable to a variety of diseases;

[0037] In the existing technology, smart fiber phase change materials are made by coating thermosensitive phase change materials with microcapsule technology and implanting them into the fiber, so that the fiber material has the function of absorbing, storing and releasing heat in the form of latent heat. During the temperature change process, the material changes between solid and liquid phases to achieve the effect of heat absorption and heat release, so that the textile fabric can respond and adjust to the temperature of the external environment, forming a stable temperature environment in the enclosed space in contact with the skin, giving the human body a sense of comfort.

[0038] Polyurethane sponge has good elasticity, making patients more comfortable when wearing nursing pants and reducing the induction of pressure sores. At the same time, polyurethane sponge is breathable and water-absorbent and can absorb sweat quickly.

[0039] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the placement component 3 includes a storage pocket 301, which is fixedly installed on the back of the inner wall of the inner layer 7. A second Velcro surface 302 is fixedly installed on the back of the storage pocket 301, and a second Velcro hook surface 303 is fixedly installed on the back of the inner wall of the inner layer 7 and inside the storage pocket 301;

[0040] The gas injection assembly 6 includes a fixing plate 601, which is fixedly connected to the inside of the storage pocket 301. A support plate 606 is fixedly installed at an equal distance on the back of the fixing plate 601. A temperature sensor 607 is fixedly installed on the top of the support plate 606. An air intake pipe 602 and a circulation pipe 603 are fixedly installed on the top of the controller 9. An electromagnetic pressure relief valve 604 is fixedly installed on the front of the circulation pipe 603. An exhaust pipe 605 is fixedly installed on the bottom of the circulation pipe 603.

[0041] The pressure assembly 10 includes an air cushion 101, and rectangular blocks 108 are fixedly installed on the left and right ends of the front of the air cushion 101, and a pressure pad 102 is fixedly installed in the middle of the front of the air cushion 101. A protrusion 103 is fixedly installed on the front of the pressure pad 102, and a connecting block 104 is fixedly installed on the back of the pressure pad 102. A connecting rope 105 is fixedly installed on one side of the connecting block 104, and a limiting plate 106 is fixedly installed at one end inside the air cushion 101. A connecting valve 107 is fixedly installed at one end inside the air cushion 101 and on one side of the limiting plate 106.

[0042] The above scheme is adopted: by separating the second Velcro surface 302 from the second Velcro hook surface 303, and then placing the fixing plate 601 inside the storage pocket 301, and at the same time passing the air inlet pipe 602 and the circulation pipe 603 through the side of the outer layer 1, and docking the circulation pipe 603 and one side of the air inlet pipe 602 with the top of the controller 9, the nursing pants can be put on the patient's body, and the controller 9 is started by the air injection pump 8 to inject air into the interior of the air cushion 101 through the air inlet pipe 602. Since the interior of the air cushion 101 is in a sealed state, the gas inside the air cushion 101 gradually increases and expands, and the rectangular block 108 squeezes the patient's buttocks and pushes out the pressure pad 102, and then presses the patient's buttocks through the pressure pad 102 and the protrusion 103 respectively. The buttocks are squeezed and stimulated, and when the pressure pad 102 is pushed out, the connecting block 104 stretches the connecting rope 105 respectively. One end of the connecting rope 105 will drive the connecting valve 107, and the limiting plate 106 will limit the connecting valve 107, so that the interior of the air cushion 101 is sealed. At the same time, the controller 9 continues to inject air into the air cushion 101. The gas inside the air cushion 101 gradually increases. The air cushion 101 is in a saturated state. At this time, the gas will push open the middle part of the connecting valve 107, and the gas inside the air cushion 101 enters the interior of the next air cushion 101 through the interior of the connecting valve 107. The gas inside the first air cushion 101 will decrease, and the connecting valve 107 will be pushed open, and the pressure pad 102 will be pulled into the interior of the air cushion 101 through the connecting rope 105 respectively;

[0043] When the gas inside the first air cushion 101 gradually decreases, the connecting valve 107 will be in the initial state, sealing the interior of the first air cushion 101. Then, air will be injected into the interior of the first air cushion 101 through the controller 9. The gas inside the air cushion 101 will gradually expand and push out the pressure pad 102 to stimulate the patient's buttocks. When the gas inside the first air cushion 101 reaches a saturated state, the connecting valve 107 will be opened again. At this time, the gas will enter the interior of the next air cushion 101, and the gas inside the next air cushion 101 will push out the pressure pad 102 to stimulate the patient's buttocks. Since the air cushions 101 are connected in parallel, the gas will repeatedly enter the interior of the air cushion 101 in turn and push out the pressure pad 102 in turn, stimulating the patient's buttocks, thereby improving the blood circulation in the patient's buttocks.

[0044] When the gas enters the last air cushion 101, it will enter the controller 9 through the circulation pipe 603 for internal circulation to ensure the temperature of the gas inside the air cushion 101. At the same time, the temperature of the patient's buttocks is monitored in real time through the temperature sensor 607. If the temperature is greater than the set value, the electromagnetic pressure relief valve 604 will automatically open, and the gas inside the air cushion 101 will be discharged through the exhaust pipe 605. The controller 9 will then draw gas from the outside and inject it into the air cushion 101. The gas inside the air cushion 101 will exchange heat with the patient's buttocks, thereby reducing the temperature of the patient's buttocks.

[0045] like Figure 1 、 Figure 2 、 Figure 3 As shown, one side of the air inlet pipe 602 in the air injection assembly 6 is connected to one side of the air cushion 101, the air cushions 101 are equidistantly fixed on the front of the fixed plate 601, and the air cushions 101 are connected in parallel, and the bottom of the circulation pipe 603 in the air injection assembly 6 is connected to the last air cushion 101, the thickness of the support plate 606 is less than the thickness of the air cushion 101, the fixed plate 601 is adapted to the inside of the storage pocket 301, and the air inlet pipe 602, the circulation pipe 603 and the controller 9 are disassembly structures, and the air inlet pipe 602 and the circulation pipe 603 are both made of rubber.

[0046] The above scheme is adopted: the controller 9 is started by controlling the air injection pump 8, and air is injected into the interior of the air cushion 101 through the air inlet pipe 602. The gas will enter the interior of the air cushion 101, causing the air cushion 101 to gradually expand and push out the pressure pad 102, squeezing and stimulating the patient's buttocks, thereby promoting blood circulation. At the same time, the controller 9 will continue to inject air into the interior of the first air cushion 101, and the gas inside the first air cushion 101 will enter the interior of the second air cushion 101. The gas inside the second air cushion gradually increases and pushes out the pressure pad 102. At the same time, since the air cushions 101 are connected in parallel, the gas will enter the interior of the air cushion 101 in sequence and push out the pressure pad 102 in sequence, squeezing and stimulating the patient's buttocks, thereby improving the blood circulation of the patient's buttocks, reducing the pressure on the buttocks, and effectively avoiding the formation of pressure sores.

[0047] At the same time, the fixing plate 601 is easy to disassemble, so that the nursing pants can be washed and recycled.

[0048] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the pressure pad 102 and the air cushion 101 are made of rubber material, and one side of the connecting rope 105 is fixedly connected to one side of the connecting valve 107. The connecting valve 107 consists of six sectors and is combined into a circular ring. One side of the connecting valve 107 is in contact with one side of the limiting plate 106. A rectangular hole is opened on the surface of the limiting plate 106, and the connecting rope 105 passes through the inside of the rectangular hole.

[0049] The above scheme is adopted: air is injected into the interior of the air cushion 101 through the controller 9, the gas inside the air cushion 101 gradually increases, the air cushion 101 will gradually expand, and the pressure pad 102 will be pushed to the top. The pressure pad 102 and the convex block 103 will squeeze and stimulate the patient's buttocks. The convex block 103 makes the stimulation effect better. At the same time, the connecting rope 105 will be stretched in the process of pushing the pressure pad 102 out. Since one side of the connecting rope 105 is fixedly connected to the connecting valve 107, the connecting valve 107 is fixed by the connecting rope 105 to prevent the gas inside the air cushion 101 from pushing the connecting valve 107 open. At the same time, the gas inside the air cushion 101 is saturated. In the state, the gas inside the air cushion 101 will push the connecting valve 107 and push the connecting valve 107 open. At this time, the gas inside the first air cushion 101 will pass through the inside of the connecting valve 107 and enter the inside of the next air cushion 101. During the opening process of the connecting valve 107, the gas inside the air cushion 101 will decrease. At this time, the connecting valve 107 will be fully opened. During the opening process, the other side of the connecting rope 105 is pulled. At this time, the pressure pad 102 is pulled into the interior of the air cushion 101 under the pulling of the connecting rope 105, thereby repeatedly pushing out and retracting the pressure pad 102 to stimulate the patient's buttocks, thereby improving the blood circulation of the patient's buttocks.

[0050] The working principle and use process of the present invention:

[0051] When a paralyzed patient needs to use the nursing pants while lying in bed, the fixing rope 201 is first removed, the outer layer 1 is unfolded, and the fixing plate 601 is placed inside the storage pocket 301, so that the second Velcro surface 302 contacts the second Velcro hook surface 303, and the fixing plate 601 inside the storage pocket 301 is fixed. At the same time, the air inlet pipe 602 and the circulation pipe 603 will pass through one side of the outer layer 1 and dock with the top of the controller 9. After the gas injection component 6 and the outer layer 1 are installed, the outer layer 1 is sleeved on the patient's body, and the front and rear ends of the outer layer 1 are connected by the fixing rope 201. At the same time, the first Velcro surface 203 contacts the first Velcro hook surface 202, so that the outer layer 1 can be fixed to the patient's body. The fixing component 2 can meet the needs of paralyzed patients of different body shapes.

[0052] During use, the controller 9 is started by controlling the air injection pump 8, and air is injected into the interior of the air cushion 101 through the air inlet pipe 602. Since the interior of the air cushion 101 is in a sealed state, the gas inside the air cushion 101 gradually increases and expands, and the rectangular block 108 squeezes the patient's buttocks and pushes out the pressure pad 102 at the same time. Then, the pressure pad 102 and the convex block 103 squeeze and stimulate the patient's buttocks respectively. When the pressure pad 102 is pushed out again, the connecting block 104 stretches the connecting rope 105 respectively, and one end of the connecting rope 105 drives the connecting valve 107 to limit The positioning plate 106 will limit the connecting valve 107, so that the interior of the air cushion 101 is sealed. At the same time, the controller 9 continues to inject gas into the air cushion 101. The gas inside the air cushion 101 gradually increases. The air cushion 101 is in a saturated state. At this time, the gas will push open the middle part of the connecting valve 107. The gas inside the air cushion 101 enters the interior of the next air cushion 101 through the interior of the connecting valve 107. The gas inside the first air cushion 101 will decrease. At the same time, the connecting valve 107 will be pushed open, and the pressure pad 102 will be pulled into the interior of the air cushion 101 through the connecting rope 105.

[0053] When the gas inside the first air cushion 101 gradually decreases, the connecting valve 107 will be in the initial state, and the interior of the first air cushion 101 will be sealed. At this time, air is injected into the interior of the first air cushion 101 through the controller 9, and the gas inside the air cushion 101 gradually expands and pushes out the pressure pad 102 to stimulate the patient's buttocks. When the gas inside the first air cushion 101 reaches a saturated state, the connecting valve 107 will be opened again, and the gas will enter the interior of the next air cushion 101, and the gas inside the next air cushion 101 will push out the pressure pad 102 to stimulate the patient's buttocks. Since the air cushions 101 are connected in parallel, the gas will repeatedly enter the interior of the air cushion 101 in turn and push out the pressure pad 102 in turn, stimulating the patient's buttocks, thereby improving the blood circulation of the patient's buttocks.

[0054] When the gas enters the last air cushion 101, it will enter the controller 9 through the circulation pipe 603 for internal circulation to ensure the temperature of the gas inside the air cushion 101. At the same time, the temperature of the patient's buttocks is monitored in real time through the temperature sensor 607. If the temperature is greater than the set value, the electromagnetic pressure relief valve 604 will automatically open, and the gas inside the air cushion 101 will be discharged through the exhaust pipe 605. The controller 9 will then draw gas from the outside and inject it into the air cushion 101. The gas inside the air cushion 101 will exchange heat with the patient's buttocks, thereby reducing the temperature of the patient's buttocks and making the patient more comfortable.
