Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multi-airbag alternating inflation air mattress to prevent bedsores. Background Technology

[0002] Long-term bedridden patients (such as paralyzed patients, postoperative recoveries, and elderly disabled individuals) experience prolonged pressure on local tissues, leading to obstructed blood circulation, tissue ischemia, hypoxia, and necrosis, ultimately resulting in pressure ulcers. To alleviate the suffering of long-term bedridden patients, air mattresses are commonly used to reduce the probability of pressure ulcers. Currently, traditional air mattresses are one-piece designs. While they can distribute pressure on local tissues, they cannot provide precise and localized pressure relief for critical areas such as bony prominences. Furthermore, they have poor breathability and comfort. One-piece air mattresses hinder the evaporation of sweat and heat, creating a high-temperature and high-humidity microenvironment at the skin contact surface, which easily leads to skin maceration, decreased resistance, and increased risk of skin damage and infection. They fail to meet the comfort needs of long-term bedridden patients and cannot achieve the ideal effect of preventing pressure ulcers. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a multi-airbag alternating inflatable anti-bedsore air mattress, which solves the technical difficulties of integrated air mattresses in providing precise and localized pressure release for key areas such as bony protrusions, as well as their poor breathability and comfort.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A multi-airbag alternating inflatable anti-decubitus air mattress includes a base plate and a main air pipe. Several sets of airbag assemblies capable of inflation and deflation are provided on the top surface of the base plate. Each set of airbag assemblies is connected to a secondary air pipe for inflation and deflation. Two sets of main air pipes are installed opposite each other on both sides of the top surface of the base plate. Several closed chambers are evenly arranged in the length direction of the inner cavity of the two sets of main air pipes. Each closed chamber is connected to several secondary air pipes. A first solenoid valve is installed at the air inlet of several closed chambers. The two sets of main air pipes are connected to the main air pipe. An air pump is connected to the main air pipe.

[0005] Furthermore, the airbag assembly includes an airbag base, on which an air chamber connected to a secondary bronchial pipe is formed. Several independent airbags are installed on the top surface of the airbag base, with gaps between the airbags. Each airbag on the airbag base has a vent hole at its air inlet, which is connected to the air chamber. A second solenoid valve is installed on each vent hole.

[0006] Furthermore, the control terminal of the air pump is connected to a microcontroller control system, and the control terminal of the microcontroller control system is electrically connected to a control panel.

[0007] Furthermore, a pressure monitoring pad adapted to the size of the base plate is laid on the top surface of the airbag, and a pressure sensor is installed at the position where the bottom surface of the pressure monitoring pad contacts the airbag. The signal output terminal of the pressure sensor is connected to the signal receiving terminal of the microcontroller control system.

[0008] Furthermore, the control terminal of the microcontroller control system is electrically connected to the control terminals of the first solenoid valve and the second solenoid valve, respectively.

[0009] Furthermore, the top surface of each enclosed cavity is connected to three secondary air ducts.

[0010] Furthermore, the top surface of the pressure monitoring pad, the exterior of the secondary branch pipe, the branch pipe, and the main branch pipe are all covered with a protective layer.

[0011] Furthermore, the airbag is made of thermoplastic polyurethane material.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Gas is supplied through a main air pipe connected to an air pump. The gas output from the air pump enters the main air pipe, and the gas in the main air pipe enters two sets of main bronchial pipes. Then, it enters the closed chamber through the first solenoid valve at the air inlet of the closed chamber, and finally is delivered to each airbag assembly through multiple sets of auxiliary bronchial pipes. By controlling the opening and closing of the first solenoid valve, the inflation and deflation of the corresponding auxiliary bronchial pipes in the closed chamber can be precisely controlled, thereby realizing the inflation and deflation of multiple sets of airbag assemblies connected to the auxiliary bronchial pipes, changing the pressure on the local pressure points of the patient, and reducing the occurrence of pressure ulcers.

[0013] 2. The gas in the bronchial tube enters each ventilator through the air chamber on the airbag base, and then enters each airbag through the second solenoid valve at each ventilator. By controlling the second solenoid valve, the inflation and deflation of each airbag can be directly and precisely controlled, so as to achieve targeted pressure release on the patient's key pressure points, and further reduce the risk of pressure ulcers in these areas.

[0014] 3. The microcontroller control system is electrically connected to the input terminals of the first and second solenoid valves respectively, and automatically controls the opening and closing of the first and second solenoid valves.

[0015] 4. A pressure monitoring pad is laid on the top surface of the airbag, and a pressure sensor is installed at the position where the bottom surface of the pressure monitoring pad contacts the airbag. The pressure sensor can monitor the pressure on the patient's pressure points in real time. When the pressure exceeds the set pressure value, the microcontroller system controls the air pump to start and stop, and at the same time precisely controls the on / off state of the first and second solenoid valves to realize the automatic inflation and deflation of multiple airbags or a single airbag, thereby reducing the pressure on the patient's pressure points and reducing the occurrence of pressure ulcers.

[0016] 5. By setting up several sets of airbag components, each airbag in the airbag component is an independent airbag with ventilation gaps between them, the breathability and comfort of this device are enhanced. It can quickly promote the evaporation of sweat and heat dissipation on the skin surface of bedridden patients, keep the skin contact surface dry, reduce the risk of skin damage and infection, and meet the comfort needs of long-term bedridden patients.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] like Figure 1-5As shown, a multi-airbag alternating inflatable anti-decubitus air mattress includes a base plate 1 and a main air pipe 4. Several sets of inflatable and deflated airbag assemblies are arranged on the top surface of the base plate 1. The specific number of airbag assemblies is determined according to the patient's needs. Each set of airbag assemblies is connected to a secondary bronchial pipe 2 for inflation and deflation. Two sets of main bronchial pipes 3 are installed opposite each other on both sides of the top surface of the base plate 1. Several closed chambers 11 are evenly arranged along the length of the inner cavity of the two sets of main bronchial pipes 3. Each closed chamber 11 is connected to several secondary bronchial pipes 2. A first solenoid valve 9 is installed at the air inlet of each of the closed chambers 11. The main bronchial tube 3 and main air tube 4 are connected. The main air tube 4 is connected to an air pump 5. The gas output by the air pump 5 enters the main air tube 4. The gas in the main air tube 4 enters the two sets of main bronchial tubes 3 respectively, and then enters the closed cavity 11 through the first solenoid valve 9. Finally, it is delivered to each airbag assembly through multiple sets of auxiliary bronchial tubes 2. By controlling the opening and closing of the first solenoid valve 9, the inflation and deflation of the corresponding auxiliary bronchial tubes 2 in the closed cavity 11 can be precisely controlled, thereby realizing the inflation and deflation of multiple sets of airbag assemblies connected to the auxiliary bronchial tubes 2, changing the pressure on the local pressure points of the patient, and reducing the occurrence of pressure ulcers.

[0021] The airbag assembly includes an airbag base 7 with an air chamber 8 connected to the secondary bronchial conduit 2. Several independent airbags 6 are mounted on the top surface of the airbag base 7, with gaps between them. The specific number of airbags 6 is determined according to the patient's needs. Each airbag 6 on the airbag base 7 has a ventilation hole 12 at its air inlet, which is connected to the air chamber 8. A second solenoid valve 10 is installed on each ventilation hole 12. Gas from the secondary bronchial conduit 2 enters each ventilation hole 12 through the air chamber 8 on the airbag base, and then passes through the second solenoid valve 10 at each ventilation hole 12 before finally entering each airbag 6. By controlling the second solenoid valve 10, the inflation and deflation of each airbag 6 can be directly and precisely controlled, achieving targeted pressure release on key pressure points of the patient, further reducing the risk of pressure ulcers in these areas. The control terminal of the air pump 5 is connected to a microcontroller control system, and the control terminal of the microcontroller control system is electrically connected to a control panel.

[0022] The top surface of the airbag 6 is covered with a pressure monitoring pad 13 that is adapted to the size of the base plate 1. A pressure sensor 14 is installed at the position where the bottom surface of the pressure monitoring pad 13 contacts the airbag 6. The signal output terminal of the pressure sensor 14 is connected to the signal receiving terminal of the microcontroller control system. The signal of the pressure sensor 14 on the pressure monitoring pad 13 is transmitted to the signal receiving terminal of the microcontroller control system.

[0023] The control terminal of the microcontroller control system is electrically connected to the control terminals of the first solenoid valve 9 and the second solenoid valve 10, respectively, and the microcontroller control system automatically controls the opening and closing of the first solenoid valve 9 and the second solenoid valve 10.

[0024] Each sealed chamber 11 is connected to three secondary bronchial pipes 2, allowing the gas in the sealed chamber 11 to enter the three secondary bronchial pipes 2, thereby controlling the filling and releasing of the three secondary bronchial pipes 2.

[0025] The top surface of the pressure monitoring pad 13, the secondary bronchus pipe 2, the main bronchus pipe 4, and the main bronchus pipe 3 are all covered with a protective layer 15. The protective layer 15 is in direct contact with the patient. On the one hand, the protective layer protects the pressure monitoring pad 13, the secondary bronchus pipe 2, the main bronchus pipe 4, and the main bronchus pipe 3 from external damage, and on the other hand, it is easy to replace at any time. In order to improve the comfort of the protective layer 15 in contact with the patient, the protective layer 15 is made of soft material.

[0026] The airbag 6 is made of thermoplastic polyurethane material, which has high elasticity and flexibility. It can deform flexibly with the inflation and deflation of the airbag 6, and can closely fit different pressure points on the patient's body (such as the buttocks, back, and shoulders). This ensures effective pressure distribution and improves the patient's comfort. At the same time, the material has good resilience and is not easily deformed after repeated inflation and deflation, maintaining the support shape of the airbag 6.

[0027] In use, the number of airbag components is determined according to the patient's needs. After determining the number of airbag bases 7, the airbag bases 7 are installed on the base plate 1, and multiple independent airbags 6 are installed on the airbag bases 7. The number of airbags 6 is determined according to the patient's needs. A second solenoid valve 10 is installed on the air inlet vent 12 of the airbag 6 on the airbag base 7. The air chamber 8 of the airbag base is then connected to the secondary bronchus pipe 2. The other end of the secondary bronchus pipe 2 is connected to the closed chamber 11 of the main bronchus pipe 3. A first solenoid valve 9 is installed at the air inlet of the closed chamber 11 to connect the main bronchus pipe 3 to the main air pipe 4. A pressure monitoring pad 13 is then laid. Finally, a protective layer 15 is covered on the top surface of the pressure monitoring pad 13, the secondary bronchus pipe 2, the main air pipe 4, and the outside of the main bronchus pipe 3. Finally, the main air pipe 4 is connected to the air pump 5 and the power is turned on.

[0028] When the pressure monitoring pad 13 detects excessive pressure in a certain area of ​​the patient, the microcontroller control system controls the first solenoid valve 9. The first solenoid valve 9 controls the inflation and deflation of gas in the closed cavity 11, thereby controlling the inflation and deflation of gas in multiple sets of secondary bronchial pipes 2. Ultimately, this enables the inflation and deflation of multiple airbags 6 connected to the secondary bronchial pipes 2, achieving inflation and deflation of airbags 6 in different areas and changing the pressure at the local pressure point of the patient.

[0029] When the pressure monitoring pad 13 detects excessive pressure on a critical part of the patient's body, the microcontroller control system controls the second solenoid valve 10, thereby precisely controlling the inflation and deflation of the individual airbag 6 to achieve targeted pressure release on the critical pressure points of the patient, further reducing the risk of pressure ulcers in that area.

[0030] When the pressure monitoring pad 13 simultaneously detects excessive pressure on a certain part of the patient's body and excessive pressure on a certain critical part of the patient's body, the microcontroller control system simultaneously controls the first solenoid valve 9 and the second solenoid valve 10, thereby controlling the inflation and deflation of multiple airbags 6 at different locations and the inflation and deflation of a single airbag 6 at the critical part of the body, so as to achieve precise pressure regulation of local and specific parts to prevent pressure ulcers.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
