Pressure ulcer support device for bedridden patients

Abstract

This utility model discloses a pressure ulcer prevention support device for bedridden patients, relating to the field of medical device technology. The device includes a support frame with two or more silent air compressors and solenoid valves mounted on its outer surface, forming two groups. Each group of silent air compressors has an intake filter and silencer assembly connected to its air inlet. Through the arrangement of silent air compressors, solenoid valves, air springs, a support frame, and a small mattress, this utility model allows for alternating operation of the two groups of silent air compressors and solenoid valves when the patient is bedridden for extended periods and finds it difficult to turn over. Initially, the first group of solenoid valves opens, releasing compressed air from the first group of air springs, causing the first group of supports and the first group of small mattresses to move downwards. At this time, the second group of small mattresses supports the patient, and the patient's contact area is exposed due to the downward movement of the first group of small mattresses. This allows the two pressure-bearing areas of the patient to alternately separate from the small mattresses, releasing pressure and thus inhibiting the formation of pressure ulcers.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a pressure ulcer prevention and support device for bedridden patients. Background Technology

[0002] Depending on the severity of the illness, there are different treatments for people who are sick. For example, some patients only have a simple cold, fever, or abrasions. After examination and medication, they can go home directly without hospitalization. On the other hand, some patients have more serious illnesses and need to be hospitalized or even bedridden for a long time.

[0003] In clinical practice, patients with external fixation or unstable conditions are usually unable to turn over, otherwise it is easy to injure the affected area and aggravate pain and discomfort. Long-term bedridden patients often develop pressure sores. Even if the mattress is improved by using excellent materials to enhance its pressure distribution, skin-friendliness, breathability, and comfort, it only slows down the occurrence of pressure sores. The area in contact with the bed is still under pressure, and the probability of pressure sores is still relatively high. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a pressure ulcer prevention and support device for bedridden patients, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure ulcer prevention and support device for bedridden patients, comprising a support frame. Two or more silent air compressors and solenoid valves are mounted on the outer surface of the support frame, forming two groups. The air inlet of each group of silent air compressors is connected to an air inlet filter and a silencer assembly. The air outlet of each group of silent air compressors is connected to a check valve. An air outlet silencer is connected to one side of each group of solenoid valves. A first air supply line and a second air supply line are respectively connected between the two groups of check valves and the two groups of solenoid valves. Multiple positioning plates and multiple positioning sleeves are fixed inside the lower part of the support frame. Two sets of air springs are connected inside the multiple positioning plates. Multiple positioning posts penetrate the tops of the multiple positioning sleeves. Two sets of brackets are fixed to the tops of the multiple positioning posts. Two sets of small mattresses are connected inside the two sets of brackets.

[0006] By adopting the above technical solution, firstly, before use, the two sets of silent air compressors are started and inflate the two sets of air springs through the first and second air supply lines, respectively. At this time, the two sets of air springs expand and lift the two sets of brackets, thereby raising the two sets of small mattresses. When the patient is bedridden for a long time and finds it inconvenient to turn over, the two sets of silent air compressors and the two sets of solenoid valves work alternately. The alternation interval can be controlled by adding a timer device such as a time relay. For example, it can be set to alternate between the first set of silent air compressors and the second set of solenoid valves every two or three minutes. The first silent air compressor and the first set of solenoid valves operate; the second set of silent air compressors inflates the second set of air springs through the check valve and the second air supply line, causing the second set of supports and mattresses to move upwards to contact the patient. Then, the first set of solenoid valves opens, releasing the compressed air from the first set of air springs, causing the first set of supports and mattresses to move downwards. At this point, the second set of mattresses supports the patient, and part of the patient's contact area is exposed due to the downward movement of the first set of mattresses. Afterwards, the first set of silent air compressors inflates the first set of air springs through the check valve and the first air supply line, causing... The first set of supports and mattresses moves upward to contact the patient. Then, the second set of solenoid valves opens, releasing compressed air from the second set of air springs, causing the second set of supports and mattresses to move downward. At this point, the first set of mattresses supports the patient, while other parts of the patient are exposed due to the downward movement of the second set of mattresses. This cycle repeats, causing the two sets of mattresses to move up and down alternately. This ensures that some areas of the patient are always unpressurized, thus preventing pressure sores caused by prolonged pressure on the skin. During the operation of the silent air compressor, its low noise level, combined with the reduced airflow noise from the intake filter and silencer assembly, further reduces the noise generated during operation. The solenoid valves also reduce airflow noise during exhaust through the exhaust silencer, effectively minimizing noise from the support device and minimizing disruption to the patient's rest. Furthermore, because the positioning sleeve, positioning column, and support are all made of POM material, they offer high structural strength and are lightweight. The low coefficient of friction of POM material also effectively reduces structural wear, extending the structure's lifespan.

[0007] Furthermore, the first and second air supply lines are respectively connected to two sets of air springs.

[0008] By adopting the above technical solution, the second set of silent air compressors inflates the second set of air springs through the check valve and the second air supply line, causing the second set of brackets and mattresses to move upwards and contact the patient. Subsequently, the first set of solenoid valves opens to release the compressed air in the first set of air springs, causing the first set of brackets and mattresses to move downwards. At this time, the second set of mattresses supports the patient, and part of the patient's contact area is exposed due to the downward movement of the first set of mattresses. Afterwards, the first set of silent air compressors inflates the first set of air springs through the check valve and the first air supply line, causing the first set of brackets and mattresses to move upwards and contact the patient. Subsequently, the second set of solenoid valves opens to release the compressed air in the second set of air springs, causing the second set of brackets and mattresses to move downwards. At this time, the first set of mattresses supports the patient, and the remaining part of the patient's body is exposed due to the downward movement of the second set of mattresses.

[0009] Furthermore, the air spring is in contact with the bottom of the bracket.

[0010] By adopting the above technical solution, when the two sets of silent air compressors start up, they respectively inflate the two sets of air springs through the first air supply line and the second air supply line. At this time, the two sets of air springs expand and lift the two sets of brackets, thereby raising the two sets of small mattresses.

[0011] Furthermore, the positioning post and the positioning sleeve are slidably connected, and both the positioning post and the positioning sleeve are made of POM material.

[0012] By adopting the above technical solution, compared with traditional mattresses, since multiple small mattresses are combined into one large mattress, there is no vertical limiting structure and it can be directly picked up and put in. Therefore, it can be transported in sections during subsequent handling, avoiding the inconvenience of transporting and drying large and heavy mattresses. When placing, the bracket is positioned by positioning sleeves and positioning posts, and the horizontal direction is limited to prevent the bracket from shifting and affecting the lifting work.

[0013] Furthermore, the bracket is made of POM material, and the two sets of brackets are slidably connected to each other, and the two sets of brackets are slidably connected to the support.

[0014] By adopting the above technical solution, the two sets of small brackets move up and down alternately, which in turn drives the two sets of small mattresses to move up and down alternately, so that some areas of the patient are always free from pressure, thereby avoiding the occurrence of pressure sores caused by long-term pressure on the patient's skin. In addition, POM material has the property of low surface friction coefficient, which can effectively reduce structural wear and thus extend the service life of the structure.

[0015] Furthermore, the mattress consists of a fabric, a mesh, and filling, wherein the fabric is an antibacterial cotton fabric, and the filling is latex, gel, or slow-rebound memory foam.

[0016] By adopting the above technical solutions, the small mattress uses skin-friendly fabric and fillings with strong pressure-dispersing and breathable properties, which can slow down the formation of pressure sores. When used in conjunction with the support structure, it can effectively inhibit the occurrence of pressure sores.

[0017] Furthermore, a stop is connected to the outer surface of the bracket, and the stop is detachably connected to the bracket by bolts.

[0018] By adopting the above technical solution, the silent air compressor and solenoid valve can be prevented from being damaged when medical staff and nurses move items. During maintenance, the bolts can be removed to disassemble the baffle, which avoids the baffle from affecting maintenance. The silent air compressor, intake filter silencer assembly, solenoid valve, exhaust silencer, first air supply line and second air supply line can be covered to increase aesthetics.

[0019] Furthermore, the bracket and the top of the mattress are both rounded.

[0020] By adopting the above technical solution, the edges of the support and the small mattress are rounded and without sharp corners, preventing patients, medical staff and nursing staff from bumping into the edges of the support and getting scratched.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model utilizes a silent air compressor, solenoid valves, air springs, a support frame, and a small mattress. When a patient is bedridden for extended periods and finds it difficult to turn over, two sets of silent air compressors and two sets of solenoid valves work alternately. Initially, the first set of solenoid valves opens, releasing compressed air from the first set of air springs, causing the first set of support frames and the first set of small mattresses to move downwards. At this time, the second set of small mattresses supports the patient, and some of the patient's contact areas are exposed due to the downward movement of the first set of small mattresses. Then, the first set of silent air compressors inflates the first set of air springs through a check valve and a first air supply line, causing the first set of support frames and small mattresses to move upwards and return to their original positions. Simultaneously, the second set of solenoid valves opens, releasing compressed air from the second set of air springs, causing the second set of support frames and the second set of small mattresses to move downwards. At this time, the first set of small mattresses supports the patient, and the remaining areas of the patient are exposed due to the downward movement of the second set of small mattresses. This allows the two pressure-bearing areas of the patient to alternately separate from the small mattresses, releasing pressure and thus inhibiting the formation of pressure ulcers.

[0023] 2. This utility model, through the setting of positioning sleeve, positioning post, bracket and small mattress, compared with the traditional mattress, uses multiple small mattresses to form a large mattress. There is no vertical limiting structure and it can be directly picked up and put in. Therefore, it can be transported in sections during subsequent transportation, avoiding the inconvenience of large and heavy mattresses for transportation and drying. When placing, the positioning sleeve and positioning post are used to position the bracket and limit the horizontal direction to prevent the bracket from shifting and affecting the lifting work; it is also convenient to disassemble and clean.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] Example 1:

[0033] Pressure ulcer support devices for bedridden patients, such as... Figures 1-5As shown, the system includes a bracket 1, characterized in that: two or more silent air compressors 3 and solenoid valves 5 are mounted on the outer surface of the bracket 1, divided into two groups; the inlet end of each group of silent air compressors 3 is connected to an inlet filter silencer assembly 4; the outlet end of each group of silent air compressors 3 is connected to a check valve 15; an outlet silencer 6 is connected to one side of each group of solenoid valves 5; a first air supply line 7 and a second air supply line 8 are respectively connected between the two groups of check valves 15 and the two groups of solenoid valves 5; multiple positioning plates 9 and multiple positioning sleeves 11 are fixed inside the lower part of the bracket 1; two sets of air springs 10 are respectively connected inside the multiple positioning plates 9; the first air supply line 7 and the second air supply line 8 are respectively connected to the two sets of air springs 10; multiple positioning sleeves 11 have multiple... Each positioning post 12 is slidably connected to a positioning sleeve 11. Both the positioning post 12 and the positioning sleeve 11 are made of POM material. Two sets of brackets 13 are fixed to the top of each positioning post 12. An air spring 10 contacts the bottom of the bracket 13. The brackets 13 are also made of POM material. The two sets of brackets 13 are slidably connected to each other and to the support 1. Two small mattresses 14 are connected inside each of the two sets of brackets 13. A second silent air compressor 3 inflates the second set of air compressors through a check valve 15 and a second air supply line 8. The second set of brackets 13 and the small mattresses 14 then move upwards to contact the patient. Subsequently, the first solenoid valve 5 opens to release the compressed air from the first set of air springs 10, allowing the first set of brackets to... The first set of small mattresses 13 and 14 move downwards, at which point the second set of small mattresses 14 supports the patient, and part of the patient's contact area is exposed due to the downward movement of the first set of small mattresses 14. Then, the first set of silent air compressors 3 inflates the first set of air springs 10 through the check valve 15 and the first air supply line 7, causing the first set of brackets 13 and small mattresses 14 to move upwards and contact the patient. Subsequently, the second set of solenoid valves 5 opens to release the compressed air from the second set of air springs 10, causing the second set of brackets 13 and the second set of small mattresses 14 to move downwards. At this point, the first set of small mattresses 14 supports the patient, and the remaining part of the patient's body is exposed due to the downward movement of the second set of small mattresses 14. This cycle repeats, causing the two sets of small mattresses 14 to move up and down alternately, thus providing overall support to the patient. Some areas are not subjected to pressure, thus preventing pressure sores from developing on the patient's skin due to prolonged pressure. During the operation of the silent air compressor 3, its own low noise level, along with the reduced airflow noise during intake by the intake filter silencer assembly 4, further reduces the noise generated by the silent air compressor 3. Additionally, the solenoid valve 5 reduces airflow noise during exhaust through the exhaust silencer 6, effectively reducing the noise generated by the lifting device and minimizing the impact on the patient's rest. Furthermore, since the positioning sleeve 11, positioning column 12, and bracket 13 are all made of POM material, they have high structural strength and are lightweight. The low coefficient of surface friction of POM material effectively reduces structural wear and extends the service life of the structure.

[0034] See Figures 1-5 In the above embodiment, the small mattress 14 consists of fabric, bed net and filling. The fabric is antibacterial cotton fabric, and the filling is latex, gel or slow rebound memory foam. The small mattress is still composed of filling, elastic elements, fabric and other structures, but its size is smaller than that of a traditional mattress. The skin-friendly fabric and the filling with strong pressure dispersion and breathability used in the small mattress 14 can slow down the formation of pressure sores. When used with the support structure, it can effectively inhibit the occurrence of pressure sores.

[0035] Example 2:

[0036] Based on the above embodiment one, the following settings are now implemented to enhance protection.

[0037] See Figures 1-5 In the above embodiment, a baffle 2 is connected to the outer surface of the bracket 1. The baffle 2 is detachably connected to the bracket 1 by bolts to prevent medical staff and nurses from bumping into the silent air compressor 3 and solenoid valve 5 when moving items. It can also cover the silent air compressor 3, the intake filter silencer assembly 4, the solenoid valve 5, the exhaust silencer 6, the first air supply line 7 and the second air supply line 8 to increase aesthetics. The bracket 1 and the small mattress 14 are all provided with rounded corners around the top to prevent patients, medical staff and nurses from bumping into the edge of the bracket and being scratched.

[0038] The implementation principle of this utility model is as follows: First, before use, the two sets of silent air compressors 3 are started and respectively fill the two sets of air springs 10 through the first air supply line 7 and the second air supply line 8. At this time, the two sets of air springs 10 expand and lift the two sets of brackets 13 respectively, thereby raising the two sets of small mattresses 14.

[0039] When patients are bedridden for a long time and it is inconvenient for them to turn over, the two sets of silent air compressors 3 and the two sets of solenoid valves 5 work alternately. The interval between alternation can be controlled by adding a timer device such as a time relay. For example, it can be set to alternate between the first set of silent air compressors 3 and the second set of solenoid valves 5 every two or three minutes.

[0040] The second set of silent air compressors 3 inflates the second set of air springs through the check valve 15 and the second air supply line 8. The second set of brackets 13 and the small mattress 14 then move upwards to contact the patient. Subsequently, the first set of solenoid valves 5 opens to release the compressed air from the first set of air springs 10, causing the first set of brackets 13 and the first set of small mattresses 14 to move downwards. At this point, the second set of small mattresses 14 supports the patient, and part of the patient's contact area is exposed due to the downward movement of the first set of small mattresses 14. Afterwards, the first set of silent air compressors 3 inflates the first set of air springs 10 through the check valve 15 and the first air supply line 7. When spring 10 is inflated, the first set of supports 13 and small mattress 14 move upwards to contact the patient. Then, the second set of solenoid valves 5 opens to release the compressed air in the second set of air springs 10, causing the second set of supports 13 and small mattress 14 to move downwards. At this time, the first set of small mattress 14 supports the patient, while the other part of the patient is exposed due to the downward movement of the second set of small mattress 14. This cycle repeats, causing the two sets of small mattress 14 to move up and down alternately. This ensures that some areas of the patient are not under pressure, thus preventing pressure sores caused by prolonged pressure on the patient's skin.

[0041] During the operation of the silent air compressor 3, its own low noise level, coupled with the reduced airflow noise during intake due to the intake filter silencer assembly 4, further reduces the noise generated during operation. Additionally, the solenoid valve 5 reduces airflow noise during exhaust through the exhaust silencer 6, effectively minimizing noise generated by the support device and reducing its impact on patient rest. Furthermore, the positioning sleeve 11, positioning column 12, and bracket 13 are all made of POM material, resulting in high structural strength and light weight. The low coefficient of friction of POM material effectively reduces structural wear, extending the structure's lifespan. The small mattress 14 uses skin-friendly fabric and breathable filling with strong pressure-dispersing properties, slowing the formation of pressure ulcers. Combined with the support structure, this effectively inhibits the occurrence of pressure ulcers. The first set of air springs 10, bracket 13, and small mattress 14, as well as the second set of air springs 10, bracket 13, and small mattress 14, can be arranged in an alternating, parallel, or side-by-side pattern.
