Description

Technical Field

[0001] This invention relates to the field of medical inflatable mattresses, and more specifically to a medical inflatable mattress. Background Technology

[0002] Pressure ulcers, also known as bedsores or pressure injuries, are injuries, ulcers, or necrosis caused by prolonged pressure on local tissues, leading to impaired blood circulation, ischemia, hypoxia, and malnutrition of the skin and subcutaneous tissues.

[0003] Currently, medical air mattresses are a core professional device for the prevention and adjunctive treatment of pressure ulcers (also known as pressure injuries). Their main mechanism of action is to redistribute pressure between the body and the mattress surface through active or passive means, preventing local tissue ischemia and necrosis caused by prolonged pressure. Existing medical air mattresses generally have multiple inflation tubes, with the height adjusted by alternating inflation through these tubes. This approach, on the one hand, prevents the use of massage for the patient, and on the other hand, relies solely on the inflation tubes, limiting the height at which the patient can be lifted. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a medical inflatable mattress that solves the shortcomings of existing medical inflatable mattresses that rely solely on alternating inflation through inflation tubing to adjust the mattress height. These shortcomings include the inability to massage patients and the limited height that can be raised by relying solely on inflation tubing.

[0005] The technical solution adopted in this invention is as follows: A medical-grade inflatable mattress includes, from top to bottom, a gel layer, a support and cushioning layer, and a bottom layer. The support and cushioning layer includes several support plates and multiple sets of inflation tubes arranged at the bottom of the support plates. Each set of inflation tubes includes an air inlet tube, an air outlet tube, and a U-shaped coil. Multiple massage and impact components are mounted on the support plates. Each massage and impact component includes a central tube, which connects to the U-shaped coil and a horizontal tube. A drive component is mounted on the outside of the central tube. A movable ring is mounted above the output end of the drive component. The movable ring is connected to an upper sliding sleeve via a connecting rod. The upper sliding sleeve is mounted on the top of the central tube. A horizontal shaft is provided inside the upper sliding sleeve. A hollow massage ball is mounted on the horizontal shaft. Ventilation holes on the horizontal shaft connect to the interior of the massage ball. Multiple vertical holes are provided on the upper sliding sleeve. A horizontal hole with both ends connecting to the vertical holes is provided inside the horizontal shaft. A sealing end is provided at the top of the central tube. The top of the sealing end has a concave surface adapted to the massage ball. The lower part of the vertical holes connects to the cavity below the central tube through side holes. This invention, through alternating inflation, avoids the need for prolonged fixed-position changes of pressure points during surgery, eliminating the need for turning over and reducing the risk of pressure sores. The use of a drive device to move the movable ring and upper sliding sleeve up and down together allows for localized massage of the patient, further reducing the risk of pressure sores. With alternating inflation via inflation tubing, when one side of the patient needs to be lifted, the drive device pushes the movable ring and upper sliding sleeve upwards, allowing for further adjustment of the height of the medical air mattress, facilitating patient transport and turning by caregivers or nurses.

[0006] Optionally, the two ends of the U-shaped coil are connected to an air inlet pipe and an air outlet pipe, respectively. One end of each air inlet pipe and air outlet pipe is connected to a heating air pump through an external pipeline. The protruding section of the U-shaped coil is located on the outside of the supporting plate. The inner side of the U-shaped coil is provided with multiple rows of horizontal pipes with open ends. The horizontal pipes of two adjacent sets of air inlet pipes are interwoven.

[0007] Optionally, the surface of the massage ball is provided with a plurality of friction-enhancing protrusions, which are made of a heat-conducting material, and the bottom wall of the concave surface is also made of a heat-conducting material.

[0008] Optionally, the massage ball has deformability.

The connecting pipes are equipped with electromagnetic control valves, and the drive component, the heating air pump, and the electromagnetic control valve are connected to an external control unit.

[0010] Optionally, each support plate corresponds to two sets of inflation lines.

[0011] Optionally, the top of the massage impact component extends through the gel layer.

[0012] Optionally, the gel layer, the support buffer layer, and the bottom layer are covered with a surface layer.

[0013] Optionally, a temperature sensor is provided inside the U-shaped coil, and a pressure sensor is provided inside the massage ball. The temperature sensor and the pressure sensor are connected to the control unit.

[0014] This invention discloses a method of using a medical-grade air mattress, comprising the following steps: A method for using a medical-grade air mattress includes the following steps: The control unit controls the electromagnetic control valve to operate, so that one set of inflation lines is filled with hot air and the other set of inflation lines is disconnected, causing one side of the support plate to rise. At this time, the control unit controls the drive component on the raised side of the support plate to operate, pushing the movable ring to move upward and pushing the massage ball to lift the human body. And / or, the control unit receives temperature information collected by the temperature sensor in the U-shaped coil, controls the electromagnetic control valves on the air inlet and outlet pipes to regulate the airflow into the inflation line, thereby controlling the temperature inside the medical air mattress; And / or, the control unit receives the pressure signal sent by the massage ball, determines the pressure point of each massage ball, and periodically adjusts the height of each massage ball in conjunction with the inflation tube to adjust the patient's pressure point. At the same time, for pressure ulcer wounds, the control unit pushes the movable ring down to lower the massage ball, so that the gel layer can directly contact the wound surface and prevent further damage.

[0015] The beneficial effects of the present invention include at least the following: 1. This invention, through alternating inflation, avoids the need for prolonged fixed-position changes of pressure points during surgery, eliminating the need for turning over and reducing the risk of pressure sores. The use of a drive device to move the movable ring and upper sliding sleeve up and down together allows for localized massage of the patient, further reducing the risk of pressure sores. With alternating inflation via inflation tubing, when one side of the patient needs to be lifted, the drive device pushes the movable ring and upper sliding sleeve upwards, allowing for further adjustment of the height of the medical air mattress, facilitating patient transport and turning by caregivers or nurses.

[0016] 2. In this invention, the control unit receives the pressure signal sent by the massage ball, determines the force point of each massage ball, and periodically adjusts the height of each massage ball in conjunction with the inflation tube to adjust the patient's pressure point. At the same time, for pressure ulcers, it pushes the movable ring down to lower the massage ball, so that the gel layer can directly contact the ulcer and prevent further damage.

[0030] In some embodiments, the driving component may also be a magnetic generator, and the movable ring may be a permanent magnet. When the magnetic generator is energized, it generates a magnetic force that repels the movable ring.

[0031] In some embodiments, the massage ball has deformability.

[0037] This invention also discloses a method of using a medical-grade air mattress, comprising the following steps: The control unit controls the electromagnetic control valve to operate, so that one set of inflation lines is filled with hot air and the other set of inflation lines is disconnected, causing one side of the support plate to rise. At this time, the control unit controls the drive component on the raised side of the support plate to operate, pushing the movable ring to move upward and pushing the massage ball to lift the human body. And / or, the control unit receives temperature information collected by the temperature sensor in the U-shaped coil, controls the electromagnetic control valves on the air inlet and outlet pipes to regulate the airflow into the inflation line, thereby controlling the temperature inside the medical air mattress; And / or, the control unit receives the pressure signal sent by the massage ball, determines the pressure point of each massage ball, and periodically adjusts the height of each massage ball in conjunction with the inflation tube to adjust the patient's pressure point. At the same time, for pressure ulcer wounds, it pushes the movable ring down to lower the massage ball, so that the gel layer can directly contact the wound surface and prevent further damage.

[0038] Example 1

[0039] The technical solution adopted in this invention is as follows: like Figure 1 , Figure 2 and Figure 3 As shown, this invention discloses a medical inflatable mattress, comprising, from top to bottom, a gel layer 1, a support and cushioning layer 2, and a bottom layer 3, wherein the gel layer, support and cushioning layer, and bottom layer are covered by a surface layer 4. The bottom layer is connected to an inflation tube.

[0040] In this embodiment, the surface layer is made of PE. The bottom layer is made of PVC. The supporting plate is made of high-elasticity sponge.

[0041] The supporting buffer layer includes several supporting plates 5 and two sets of inflation pipes 6 arranged at the bottom of the supporting plates. Each set of inflation pipes includes an air inlet pipe 7, an air outlet pipe 8 and a U-shaped coil 9. The two ends of the U-shaped coil are connected to the air inlet pipe and the air outlet pipe, respectively. One end of each of the air inlet pipe and the air outlet pipe is connected to a heating air pump 10 through an external pipe. The protruding section of the U-shaped coil is located on the outside of the supporting plate. The inner side of the U-shaped coil is provided with multiple rows of horizontal pipes 11 with open ends. The horizontal pipes of adjacent sets of inflation pipes are interwoven.

[0042] In another embodiment, a partition 30 is provided inside the support buffer layer to divide the lower part of the support buffer layer into two independent cavities.

[0043] The support plate is equipped with multiple massage and impact components 12, with each support plate corresponding to two sets of inflation lines. The top of each massage and impact component passes through the gel layer. A partition on the support plate divides the support buffer layer into two sets of cavities.

[0044] like Figure 4 and Figure 5As shown, the massage impact assembly includes a central tube 13, which connects a U-shaped coil and a horizontal tube. A drive component 14 is mounted on the outside of the central tube. A movable ring 15 is mounted above the output end of the drive component. The movable ring is connected to an upper sliding sleeve 17 via a connecting rod 16. The upper sliding sleeve is installed on the top of the central tube. A horizontal shaft 18 is provided inside the upper sliding sleeve. A hollow, rollable massage ball 19 is mounted on the horizontal shaft. A vent hole 20 is provided on the horizontal shaft to connect to the inside of the massage ball. A plurality of vertical holes 21 are provided on the upper sliding sleeve. A horizontal hole 22 is provided inside the horizontal shaft with both ends connected to the vertical holes. A sealing end 23 is provided at the top of the central tube. A concave surface 24 adapted to the massage ball is provided at the top of the sealing end. The lower part of the vertical holes is connected to the cavity below the central tube through a side hole 29.

[0045] In this embodiment, the driving component is an electric push rod, and the output shaft of the electric push rod is connected to a movable ring.

[0046] In this embodiment, the horizontal axis of the upper sliding sleeve is parallel to the concave surface of the U-shaped coil and parallel to the air inlet or outlet pipe. When the control unit controls the drive component on the raised side support plate to operate, it pushes the movable ring upward, pushing the massage ball to lift the human body. The massage ball can reduce the resistance of the human body's lateral movement, facilitating the handling and transfer of the human body. When the movable ring is at its lowest point, the height of the massage ball is less than 80% of the height of the gel layer.

[0047] The heating air pump is provided with multiple connecting pipes 26 that communicate with the air inlet pipe and the air outlet pipe. The connecting pipes are equipped with electromagnetic control valves 27. The drive component, the heating air pump, and the electromagnetic control valve are connected to an external control unit.

[0048] A temperature sensor is installed inside the U-shaped coil, and a pressure sensor is installed inside the massage ball. The temperature sensor and the pressure sensor are connected to the control unit.

[0049] In this embodiment, the control unit controls the electromagnetic control valve to operate, so that one set of inflation lines is filled with hot air and the other set of inflation lines is disconnected, causing one side of the support plate to rise. At this time, the control unit controls the drive component on the raised side of the support plate to operate, pushing the movable ring to move upward and pushing the massage ball to lift the human body. During this process, the massage ball will roll.

[0050] The control unit receives temperature information collected by the temperature sensor in the U-shaped coil, and controls the electromagnetic control valves on the air inlet and outlet pipes to regulate the airflow into the inflation pipeline, thereby controlling the temperature inside the medical air mattress.

[0051] Example 2

[0052] The difference between this embodiment 2 and embodiment 1 is that, as Figure 6As shown, the surface of the massage ball is provided with a plurality of friction-enhancing protrusions 25, which are made of a heat-conducting material.

[0053] Example 3

[0054] The difference between Example 3 and Example 1 is that, as Figure 7 As shown, the massage ball has multiple friction-enhancing protrusions on its surface, which are made of a thermally conductive and elastic material. The massage ball has deformation capability. The bottom of the sealing end of the upper sliding sleeve is a concave plate 28 that conforms to the shape of a concave surface. The bottom wall of the concave plate is made of a thermally conductive material, and the concave plate itself is made of a thermally conductive metal.

[0055] In this embodiment, by pushing the movable ring down, the massage ball contacts the concave plate, improving heat exchange efficiency and avoiding low heat exchange efficiency due to insufficient airflow through the vent holes; the massage ball has a high internal temperature, which can heat and massage the human body, improving the massage effect.

[0056] Example 4

[0057] This invention also discloses a method of using a medical-grade air mattress, comprising the following steps: The control unit controls the electromagnetic control valve to operate, causing one set of inflation lines to be filled with hot air and the other set of inflation lines to be disconnected, causing one side of the support plate to rise. At this time, the control unit controls the drive component on the raised side of the support plate to operate, pushing the movable ring to move upward and pushing the massage ball to lift the human body.

[0058] The control unit receives temperature information collected by the temperature sensor in the U-shaped coil, and controls the electromagnetic control valves on the air inlet and outlet pipes to regulate the airflow into the inflation pipeline, thereby controlling the temperature inside the medical air mattress.

[0059] The control unit receives the pressure signal sent by the massage balls, determines the pressure point of each massage ball, and periodically adjusts the height of each massage ball in conjunction with the inflation tubing to adjust the pressure point of the patient. At the same time, for pressure ulcers, the control unit pushes the movable ring down to lower the massage balls, so that the gel layer can directly contact the ulcer and prevent further damage.

[0060] When a patient needs massage, the massage balls at the massage point can be controlled to move rhythmically up and down for massage. Combined with the circulatory inflation on both sides and the horizontal axis of the upper sliding sleeve parallel to the concave surface of the U-shaped coil, the patient can move periodically and automatically along the lateral direction, improving massage efficiency.

[0061] When the gas temperature inside the U-shaped coil is below two-thirds of the rated value and continues to rise within 3 minutes, all the massage balls are pushed to move down and up in a cycle. Under the action of surface tension, the massage balls roll and contact the concave plates, causing the temperature inside the massage balls to rise rapidly. Once the gas temperature inside the U-shaped coil rises to the rated temperature, the massage begins.

[0062] In this embodiment, the rated gas temperature inside the U-shaped coil is 30-60℃, set according to actual needs. When the patient's symptoms are mild or they are not ill, the rated temperature of the U-shaped coil is set to 60℃. When the patient's symptoms are severe, the rated temperature of the U-shaped coil is set to 30℃.

[0063] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
