Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically an inflatable positioning pad for supporting the patient's position during surgery. Background Technology

[0002] In surgical procedures, positioning pads are crucial for maintaining the patient's position and ensuring surgical safety. Traditional positioning pads are mostly made of fixed-shape sponge or rubber, which have the following drawbacks:

[0003] (1) The fixed structure cannot be adapted to patients of different body types, and it is difficult to meet the positional support requirements of different surgeries, which can easily lead to insufficient local support or excessive compression.

[0004] (2) Patients need to maintain the same position for a long time during the operation. Traditional positioning pads lack pressure distribution structure. Local tissues are compressed beyond the capillary tolerance limit, which can easily lead to complications such as pressure sores and nerve damage.

[0005] (3) Although the existing inflatable positioning pads have basic inflation functions, the inflation adjustment process relies on the experience of medical staff to manually adjust, which makes it impossible to detect local pressure abnormalities in a timely manner. The adjustment accuracy and efficiency are low, making it difficult to meet the requirements of clinical surgery for the safety and comfort of positioning management. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides an inflatable positioning pad, which solves the problems of poor adaptability, uneven pressure distribution and lack of pressure feedback of traditional positioning pads by using a modular airbag structure and a sub-airbag structure with a honeycomb topology arrangement inside, thereby improving the safety and comfort of surgical positioning support.

The modular airbag assembly comprises multiple independently controlled airbag sections, each containing 3-6 independent sub-airbags, all of which are arranged in a honeycomb topology. The pressure monitoring assembly includes several thin-film pressure sensors, with one sensor embedded in each sub-airbag. The airway assembly includes a valve matrix, a main air pipe, and branch air pipes, with each valve in the valve matrix connected to the inflation port of a sub-airbag via a branch air pipe. The heating assembly includes carbon fiber heating wires distributed between the two layers of composite material in the sub-airbags. The support frame, made of shape memory alloy, is fixed to the bottom of the modular airbag assembly in a grid pattern.

[0011] Preferably, the sub-airbag is made of a double-layer composite material, with an inner layer of TPU and an outer layer of high-elasticity silicone, and the two layers are integrally formed by hot pressing.

[0012] Preferably, the sub-airbag is made of multiple layers, consisting of a TPU layer, a carbon fiber heating wire, and a high-elasticity silicone layer from the inside out, with an antibacterial coating on the surface of the high-elasticity silicone.

[0020] (III) Beneficial Effects

[0021] This invention's inflatable positioning pad features modular airbag partitions and independent air valve control, allowing for adjustment of support in each area according to the patient's body shape and surgical needs. This solves the problem of poor adaptability in traditional positioning pads. The honeycomb-shaped micro-cell topology of the sub-airbags, combined with a shape memory alloy support frame, achieves uniform weight distribution. Combined with pressure monitoring via an embedded thin-film pressure sensor, it effectively prevents pressure sores and nerve damage caused by excessive local pressure. The shape memory alloy frame supports vacuum folding, reducing its volume to 1 / 5 of its original size, facilitating sterilization and storage. Furthermore, it automatically returns to its original shape after inflation, reducing the workload for medical staff.

[0022] In some preferred embodiments, the sub-balloon is made of a double-layer composite material, which has puncture-resistant, antibacterial, and antistatic properties. The carbon fiber heating wire can maintain the patient's body temperature during the operation and reduce the risk of hypothermia. Attached Figure Description

[0028] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This utility model provides an inflatable air level pad, including a modular airbag assembly, a pressure monitoring assembly, an air passage assembly, a heating assembly, and a support frame. The components are connected by hardware to form a complete support system, and the specific structure is as follows:

[0030] 1. Modular airbag assembly

[0031] like Figure 1 As shown, the modular airbag assembly 1 comprises four independently controlled airbag zones: a head and neck airbag 11, a chest airbag 12, a waist and hip airbag 13, and a leg airbag 14. Each airbag zone contains 3-6 independent sub-airbags 110. The figure shows four airbag zones as an example. These airbag zones are connected by a flexible, bendable band 15. The flexible band 15 is located in a recessed area to allow for the routing of branch airways.

[0032] All sub-airbags 110 have a honeycomb topological arrangement inside, consisting of several hexagonal honeycomb-shaped small air cells spliced ​​together. Each honeycomb-shaped small air cell forms a partition 1110 with adjacent honeycomb-shaped small air cells, and the partition surface is provided with several ventilation holes (such as... Figure 2 As shown, the small air chambers in each sub-airbag 110 share a common top wall and bottom. The upper and lower ends of the partition surface 1110 are not connected to the top wall or bottom, thus forming a channel for gas flow. The partition surface 1110 of adjacent small air chambers serves to bear weight and evenly distribute the pressure borne by the airbag. The side walls of adjacent sub-airbags 110 fit together to form a uniform load-bearing surface, with an overall load-bearing capacity of over 250 kg.

[0033] The structure of the sub-airbag 110 does not affect the inflation and deflation of each sub-airbag. At the same time, compared with the airbag with a whole air chamber structure, it has greater support force and support stability. The surface of each sub-airbag maintains a good uniform height, and it is not easy for the airbag to collapse locally when the user presses or turns over, which may cause some limbs to be squeezed and blood flow to be obstructed.

[0034] Each sub-airbag 110 has an independent inflation port 1101 and deflation port 1102 at its top. The inflation port 1101 is connected to the air circuit assembly through an air tube, enabling independent inflation and deflation of each sub-airbag 110. The sub-airbag 110 is made of double or multiple layers of composite material, with an inner layer of TPU 111 and an outer layer of high-elasticity silicone 112 (with anti-static properties). The two layers are integrally molded through a hot-pressing process, ensuring both sealing and durability.

[0035] like Figure 3 As shown, a soft pad 1' is laminated to the modular airbag assembly 1. The soft pad 1' can cover and wrap the relatively hard inflation port 1101, exhaust port 1102 and air supply pipe, etc., to avoid affecting the comfort of human use.

[0036] 2. Pressure monitoring components

[0037] The pressure monitoring component includes several thin-film pressure sensors. Each sub-airbag 110 has a thin-film pressure sensor embedded inside. The sensor thickness is ≤1mm, so it does not affect the normal inflation and support of the sub-airbag 110. The accuracy of the thin-film pressure sensor is ±1mmHg. Its signal output end extends through a wire (a wire channel pre-set in the side wall of the sub-airbag) to a terminal on the edge of the positioning pad. The terminal can be connected to an external display device to display the contact surface pressure data of each sub-airbag in real time. When the thin-film pressure sensor detects that the local pressure of the corresponding sub-airbag exceeds 32mmHg (the critical value for capillary closure), it can issue a pressure abnormality prompt through the external display device.

[0038] 3. Heating Components

[0039] The heating component includes a carbon fiber heating wire 31. The carbon fiber heating wire 31 is distributed in a mesh between the outer high-elasticity silicone 112 and the inner TPU layer 111 of the sub-airbag 110. The two ends of the carbon fiber heating wire 31 are connected to the wiring interface on the edge of the positioning pad through wires. The wiring interface can be connected to an external power adapter (the power adapter is an external general-purpose device). By adjusting the input voltage through the external power adapter, the temperature of the carbon fiber heating wire can be adjusted. The temperature adjustment range is 37-42℃, which meets the patient's temperature maintenance needs during surgery.

[0040] See Figure 4 As shown, the sub-airbag 110 is made of multiple layers, consisting of a TPU layer 111, a carbon fiber heating wire 31, and a high-elasticity silicone 112 from the inside out. The surface of the high-elasticity silicone 1112 is coated with an antibacterial coating. In this way, the carbon fiber heating wire 31 can be laminated onto the surface of the sub-airbag 110, giving the surgical pad an antibacterial effect.

[0041] 4. Gas circuit components

[0042] See Figure 5 As shown, the airway assembly 4 includes a valve matrix, a main air tube 42, and branch air tubes 43. The valve matrix is ​​a multi-channel mechanical valve group, containing independent valves 41 matching the number of sub-inflators 110. The outlet of each valve 41 is connected to the inflation port of a sub-inflator 110 via a branch air tube 43. The inlet of the valve matrix is ​​connected to the main air tube 42, which can be connected to an external air pump 44 (the air pump 44 is an external universal device and a silent air pump). By manually operating the valves of the valve matrix, independent inflation or deflation of each sub-inflator 110 can be achieved. The valve matrix is ​​equipped with a pressure gauge, which allows medical personnel to control the inflation pressure of the sub-inflators 110 as needed.

[0043] 5. Supporting frame

[0044] The support frame is made of shape memory alloy and has a grid-like structure. It is fixed to the bottom of the modular airbag assembly. The support frame is used to enhance the overall structural stability of the positioning pad. When the positioning pad is deflated, the shape memory alloy support frame can drive the airbag assembly to fold through a vacuuming operation. After folding, the volume is reduced to 1 / 5 of the original volume, which is convenient for disinfection and storage. The shape memory alloy support frame 5 has shape memory function and can automatically restore the initial support shape after inflation without manual adjustment.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
