Description

A surgical mattress that can adjust the pressure of the patient's surgical position. Technical Field

[0001] This utility model relates to the field of medical and nursing technology, and in particular to a surgical mattress that can adjust the pressure of the patient's surgical position. Background Technology

[0002] During surgery, patients typically need to maintain a fixed position for extended periods to ensure the precision of the procedure. However, this static position can lead to prolonged pressure on local tissues, especially bony prominences such as the sacrum, coccyx, scapula, and heels, obstructing blood circulation and increasing the risk of postoperative pressure ulcers. Statistics show that patients undergoing surgery exceeding two hours have a significantly higher incidence of pressure ulcers, which not only affects postoperative recovery but may also lead to medical disputes. Therefore, how to dynamically adjust patient pressure distribution through improved surgical mattress design has become a critical issue that urgently needs to be addressed in clinical nursing and medical device fields.

[0003] Currently, traditional surgical mattresses mostly use static filling with flexible materials or a single airbag structure to achieve basic support. They lack the ability to dynamically sense and precisely control real-time pressure distribution. When local pressure suddenly increases, this design cannot respond quickly and adjust the support status of specific areas accordingly, which may lead to continuous pressure on areas of concentrated pressure.

[0004] This utility model is based on the above-mentioned circumstances. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a surgical mattress that can dynamically adjust the pressure of the patient's surgical position.

[0006] This utility model is achieved through the following technical solution:

[0007] A surgical mattress capable of adjusting the pressure of a patient's surgical position includes three cushion sections: a headrest section, a backrest section, and a legrest section. Each cushion section contains multiple evenly distributed main airbags. A group of secondary airbags is located next to each main airbag, and the group of secondary airbags includes several auxiliary airbags distributed around the main airbags. A first pressure sensor is located on the upper part of each cushion section corresponding to the position of the main airbags. The surgical mattress also includes an air delivery mechanism connected to the main airbags and auxiliary airbags, and a control system that controls the air delivery mechanism to inflate and deflate each main airbag and auxiliary airbag individually.

[0008] As described above, a surgical mattress capable of adjusting the pressure of the patient's surgical position includes each main airbag and auxiliary airbag, each of which includes an air supply tube for connecting to an air source. The air delivery mechanism includes a solenoid valve on the air supply tube and an air pump at the input end of the air supply tube. The air pump is used to inflate the secondary airbag group next to the main airbag corresponding to the first pressure sensor when the detection value of the first pressure sensor is at a preset threshold, thereby dispersing the pressure of the main airbag. The air pump is a dual-purpose inflator and deflater. When the detection value of the first pressure sensor is greater than a preset limit value, the air pump is controlled to deflate the main airbag corresponding to the first pressure sensor and inflate the secondary airbag group corresponding to the main airbag, thereby making the secondary airbag group higher than the main airbag to form a support area.

[0009] As described above, a surgical mattress capable of adjusting the pressure of the patient's surgical position includes three cushion parts: the headrest, the backrest, and the legrest, each comprising a flexible outer covering. The flexible outer covering has a cavity, and a base plate is provided within the cavity. The main airbag and the auxiliary airbag are both connected to the base plate, and the first pressure sensor is connected to the upper part of the main airbag.

[0010] As described above, a surgical mattress capable of adjusting the pressure of the patient's surgical position has a through hole on its flexible outer casing for a first pressure sensor to pass through.

[0011] The surgical mattress described above, which can adjust the pressure of the patient's surgical position, has a headrest, backrest, and legrest as a single integrated structure.

[0012] The surgical mattress described above, which can adjust the pressure of the patient's surgical position, has a separate structure for the headrest, backrest, and legrest.

[0013] As described above, a surgical mattress that can adjust the pressure of the patient's surgical position includes a headrest connected to a backrest via a connecting strap, and a backrest connected to a legrest via a connecting strap.

[0014] The surgical mattress described above is capable of adjusting the pressure of the patient's surgical position, and the control system is connected to an anesthesia machine and / or a monitor.

[0015] A surgical mattress capable of adjusting the pressure of a patient's surgical position includes three cushion sections: a headrest section, a backrest section, and a legrest section. Each cushion section has multiple main air chambers, and a group of secondary air chambers is provided next to each main air chamber. The group of secondary air chambers includes several auxiliary air chambers distributed around the main air chambers. A first pressure sensor is provided on the upper surface of each cushion section corresponding to the position of the main air chamber. The surgical mattress also includes an air supply mechanism connected to the main air chambers and auxiliary air chambers, and a control system that controls the air supply mechanism to individually inflate and deflate each main air chamber and auxiliary air chamber.

[0016] As described above, a surgical mattress capable of adjusting the pressure of the patient's surgical position includes a main air chamber and an auxiliary air chamber, each of which includes an air supply pipe for connecting to an air source. The air supply mechanism includes a solenoid valve on the air supply pipe and an air pump at the input end of the air supply pipe. The air pump is used to inflate the secondary air bladder group next to the main air chamber corresponding to the first pressure sensor when the detection value of the first pressure sensor is at a preset threshold, thereby dispersing the pressure of the main air bladder. The air pump is a dual-purpose inflator and deflater. When the detection value of the first pressure sensor is greater than a preset limit value, the air pump is controlled to deflate the main air chamber corresponding to the first pressure sensor and inflate the secondary air bladder group corresponding to the main air chamber, thereby making the secondary air bladder group higher than the main air chamber to form a support ring.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] This invention, by placing a first pressure sensor at the location of the main airbag in each pillow area, combined with a real-time detection and control system, can accurately sense changes in local body pressure of the patient. When the pressure value reaches a preset threshold, the system actively inflates the secondary airbag group to disperse the pressure of the main airbag; if the pressure exceeds the limit value, the main airbag is quickly deflated and the secondary airbags are inflated to form a higher support area, realizing dynamic regulation of "pressure transfer-rebalancing". This significantly reduces blood circulation disorders caused by prolonged pressure on local tissues, fundamentally reducing the probability of intraoperative pressure ulcers.

[0019] The primary airbag provides basic support through even distribution, while the secondary airbags are arranged around it to form a "satellite" auxiliary structure. When the primary airbag needs decompression, the secondary airbags inflate and tightly fill the support gaps, avoiding the collapse or positional shift problems caused by the deflation of a single airbag in traditional designs. The coordinated mechanism of the primary and secondary airbags can both distribute pressure and maintain the overall stability of the patient's position, making it particularly suitable for surgical procedures requiring delicate manipulation.

[0020] The control system employs a tiered approach based on pressure detection values: within a threshold range, it triggers secondary airbag inflation; above the extreme value, it activates primary airbag deflation and secondary airbag reinforcement. This strategy avoids the crude "full-area inflation and deflation" operation of traditional technologies, reducing pump energy consumption and enabling rapid response to high-pressure areas, ensuring accurate and timely pressure relief.

[0021] Through a closed-loop electrical connection between sensors, solenoid valves, and air pumps, the system automatically completes the pressure monitoring, decision-making, and execution process without requiring manual adjustments by medical staff. This intelligent design not only reduces operational complexity but also avoids human judgment errors, making it particularly suitable for continuous management of body pressure during long and complex surgeries. The pressure monitoring graph can also be displayed on the control system's screen, allowing for manual intervention to prevent excessive local pressure. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] As shown in Figures 1 to 7, a surgical mattress capable of adjusting the pressure of the patient's surgical position includes three cushion sections: a headrest section 1, a backrest section 2, and a legrest section 3. Each cushion section has multiple evenly distributed main airbags 41. A secondary airbag group is provided next to each main airbag 41. The secondary airbag group includes several auxiliary airbags 42 distributed around the main airbags 41. A first pressure sensor 5 is provided on the upper part of each cushion section corresponding to the position of the main airbags 41. The surgical mattress also includes an air delivery mechanism connected to the main airbags 41 and auxiliary airbags 42, and a control system 7 that controls the air delivery mechanism to inflate and deflate each main airbag 41 and auxiliary airbag 42 individually. Each main airbag 41 and auxiliary airbag 42 includes an air supply pipe 61 for connecting to an air source. The air delivery mechanism includes a solenoid valve 62 on the air supply pipe 61 and an air pump 63 at the input end of the air supply pipe 61. The air pump 63 is used to inflate the secondary airbag group next to the main airbag 41 corresponding to the first pressure sensor 5 when the detection value of the first pressure sensor 5 is at a preset threshold, thereby dispersing the pressure of the main airbag 41. The air pump 63 is a dual-purpose air pump for inflating and deflating. When the detection value of the first pressure sensor 5 is greater than a preset limit value, the air pump 63 is controlled to deflate the main airbag 41 corresponding to the first pressure sensor 5 and inflate the secondary airbag group corresponding to the main airbag 41, thereby making the secondary airbag group higher than the main airbag 41 to form a support area.

[0032] This invention, combined with a real-time detection and control system 7, can accurately sense changes in local body pressure on the patient. When the pressure value reaches a preset threshold, the control system 7 actively inflates the secondary airbag group to disperse the pressure on the main airbag 41; if the pressure exceeds the limit, the main airbag 41 is quickly deflated and the auxiliary airbag 42 is inflated to form a higher support area, achieving dynamic regulation of "pressure transfer-rebalancing," significantly reducing blood circulation disorders caused by prolonged pressure on local tissues, and fundamentally reducing the probability of intraoperative pressure ulcers. The main airbag 41 is evenly distributed to provide basic support, and the secondary airbag group is arranged around the main airbag 41 to form a "satellite" auxiliary structure. When the main airbag 41 needs to be depressurized, the secondary airbag group is inflated and tightly fills the support gap, avoiding the collapse or positional displacement problems caused by the deflation of a single airbag in traditional designs. The linkage mechanism of the main and secondary airbags can both disperse pressure and maintain the overall stability of the patient's position, making it particularly suitable for surgical scenarios requiring delicate operations.

[0033] Furthermore, the headrest portion 1, backrest portion 2, and legrest portion 3 each include a flexible outer covering portion 81. The flexible outer covering portion 81 has a cavity 810, and a base plate 82 is located within the cavity 810. The main airbag 41 and the auxiliary airbag 42 are both connected to the base plate 82, and the first pressure sensor 5 is connected to the upper part of the main airbag 41. The flexible outer covering portion 81 can be made of fabric or plastic. The main airbag 41 and the auxiliary airbag 42 are connected to the base plate 82 by adhesive or other connection methods. The base plate 82 can be an elastic rubber sheet or other flexible material.

[0034] Furthermore, the flexible outer casing 81 is provided with a through hole 811 through which the first pressure sensor 5 passes. This reduces the obstruction between the first pressure sensor 5 and the human body, thereby obtaining more accurate values.

[0035] In one embodiment, a second pressure sensor is provided on the upper part of each pillow pad corresponding to the position of the auxiliary airbag 42 to detect the pressure value at that location. The second pressure sensor is electrically connected to the control system 7.

[0036] In one embodiment, the first pressure sensor 5 and the second pressure sensor can be flexible piezoresistive sensors with a range of 0-200 mmHg.

[0037] In one embodiment, the headrest 1, backrest 2, and legrest 3 are integrated into a single structure, making the surgical mattress more portable.

[0038] In one embodiment, the headrest 1, backrest 2, and legrest 3 are separate structures. The headrest 1 is connected to the backrest 2 via a connecting strap, and the backrest 2 is connected to the legrest 3 via a connecting strap, so that the three pillows can be placed individually to fit the different positions on the operating table more closely.

[0039] In one embodiment, the control system 7 is connected to the anesthesia machine and / or a monitor. This connection can be made via a data cable or wireless communication methods such as Bluetooth. It acquires real-time data on the patient's blood pressure, blood oxygen saturation, body temperature, and humidity. The control system 7 can be a PLC controller or a computer terminal.

[0040] In one embodiment, the preset pressure threshold is 32-40 mmHg. When the detection value of the first pressure sensor 5 is within 32-40 mmHg, the air pump 63 is controlled to inflate the secondary airbag group next to the main airbag 41 corresponding to the first pressure sensor 5 to 15 mmHg, thereby dispersing the pressure of the main airbag 41. The preset limit value is 40 mmHg. When the detection value of the first pressure sensor 5 is greater than 40 mmHg, the air pump 63 is controlled to deflate the main airbag 41 corresponding to the first pressure sensor 5 to 5 mmHg and inflate the secondary airbag group corresponding to the main airbag 41 to 20 mmHg, thereby making the secondary airbag group higher than the main airbag 41 to form a support area.

[0041] When the anesthesia machine detects that the systolic blood pressure is less than 90 mmHg, the main air bladder 41 in the headrest 1 deflates and the main air bladder 41 in the legrest 3 inflates, thereby adjusting the body position to a "head-down, feet-up" position to increase venous return. After the blood pressure stabilizes, the main air bladders 41 in the headrest 1 and legrest 3 are then inflated and deflated to reset the body position. This product not only has intelligent inflation and deflation functions to regulate pressure, but also allows for manual intervention in pressure regulation and body position adjustment via a control terminal.

[0042] This utility model also discloses a surgical mattress capable of adjusting the pressure of a patient's surgical position, comprising three cushion portions: a headrest portion 1, a backrest portion 2, and a legrest portion 3. Each cushion portion has multiple main air chambers 91, and a secondary air chamber group is provided next to each main air chamber 91. The secondary air chamber group includes several auxiliary air chambers 92 distributed around the main air chambers 91. A first pressure sensor 5 is provided on the upper surface of each cushion portion corresponding to the position of the main air chamber 91. The surgical mattress also includes an air supply mechanism connected to the main air chambers 91 and auxiliary air chambers 92, and a control system 7 that controls the air supply mechanism to individually inflate and deflate each main air chamber 91 and auxiliary air chamber 92. Each main air chamber 91 and auxiliary air chamber 92 includes a device for... An air supply pipe 61 is connected to the air source. The air delivery mechanism includes a solenoid valve 62 mounted on the air supply pipe 61 and an air pump 63 located at the input end of the air supply pipe 61. The air pump 63 is used to inflate the secondary airbag group next to the main air chamber 91 corresponding to the first pressure sensor 5 when the detection value of the first pressure sensor 5 is at a preset threshold, thereby dispersing the pressure of the main airbag 41. The air pump 63 is a dual-purpose inflator and deflater. When the detection value of the first pressure sensor 5 is greater than a preset limit value, the air pump 63 is controlled to deflate the main air chamber 91 corresponding to the first pressure sensor 5 and inflate the secondary airbag group corresponding to the main air chamber 91, so that the secondary airbag group is higher than the main air chamber 91 to form a support ring. This solution eliminates the need to place airbags inside the pillow cushion; it directly uses its own partitioned air chambers for inflation and deflation.

[0043] Furthermore, the headrest 1, backrest 2, and legrest 3 are integrated into one unit, making them easy to carry. Alternatively, the headrest 1, backrest 2, and legrest 3 can be separate units, allowing each of the three cushions to be placed individually to better fit different positions on the operating table.
