Description

Technical Field

[0001] The present invention relates to the technical field of body positioning pads, and in particular to a body positioning pad used during surgery to prevent acquired pressure injuries during surgery. Background Art

[0002] Pressure injuries are localized injuries to the skin or subcutaneous tissue at bony prominences caused by pressure, combined shear forces, and friction. Studies have shown that, under normal circumstances, the innervated skin can tolerate 5 hours or longer of ischemia. However, sustained pressure on the tissue for more than 2 hours at a pressure of 69.75 mmHg can cause irreversible damage. Modern surgery is rapidly evolving, and many procedures are performed under a microscope, significantly extending operative times. For example, cranial surgeries often last over 8 hours. Keeping the patient in the same position for extended periods significantly increases the incidence of intraoperatively acquired pressure injuries. The incidence of intraoperatively acquired pressure injuries in hospitals is 3% to 14%. Therefore, patients undergoing neurovascular surgery, which requires prolonged recumbent surgery, are at high risk for intraoperatively acquired pressure injuries.

[0003] Intraoperatively acquired pressure injury (IAPI) refers to pressure injury (PI) to the skin and subcutaneous tissue during surgery, typically located over bony prominences or at interfaces involving medical devices or equipment. IAPIs are particularly common during surgery, especially in the context of a patient's inability to turn over. The resulting pressure on the skin from the surgical position can lead to redness, induration, and blisters after prolonged surgery.

[0004] Therefore, a positioning cushion is placed to support the patient, but the existing positioning cushion is only streamlined, which is not suitable for everyone. Moreover, long-term use will cause excessive local pressure, making it difficult to adjust the local pressure. Summary of the Invention

[0005] The purpose of the present invention is to provide a positioning pad for use during surgery to prevent acquired pressure injuries during surgery, and to solve the following technical problems: the positioning pad provides support, but the existing positioning pad is only designed to be streamlined, which is not suitable for everyone, and long-term use will cause excessive local pressure, making it difficult to adjust the local pressure.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A positioning pad used during surgery to prevent acquired pressure injuries during surgery includes a base pad, a wave pad is provided on the top of the base pad, the wave pad is a hollow structure, a plurality of sealing pads are provided inside the wave pad, the sealing pads form the wave pad into a plurality of airbag placement areas, each of the airbag placement areas is provided with an airbag and a heating rod, the airbag is connected to an airbag inflation port opened on the wave pad, the airbag inflation port is connected to an air source through a hose, and each of the hoses is installed with a control valve.

[0007] As a further solution of the present invention: a pressure sensor is embedded in the wave pad, and the pressure sensor is used to measure the pressure values ​​of different areas of the wave pad, and then transmit the pressure value signal to the controller, and the controller controls the air source and the control valve to open inflation.

[0008] As a further solution of the present invention: a plurality of through holes are provided on the wave pad.

[0009] As a further solution of the present invention: a driving motor is fixedly installed inside the base pad, and a driving wheel is fixedly installed on the output shaft of the driving motor; The inner array of the base pad is provided with a plurality of driven wheels and a balance wheel. The driving wheel, the driven wheel and the balance wheel are sleeved with a belt, and the belt is wound around the driven wheel in an S-shape. A threaded rod is fixedly mounted on the driven wheel, and the threaded rod is provided with multiple sections of double-groove threads, and a cam is sleeved on the threaded rod. A plurality of lifting buckets are arranged in an array above the threaded rod, connecting blocks are fixedly installed on both sides of the lifting buckets, a guide column is inserted into the bottom of the connecting block, a spring is sleeved on the guide column, and the lifting buckets are rotatably connected to massage balls.

[0010] As a further solution of the present invention: a rotary motor is fixedly installed inside the lifting barrel, a rotary disk is fixedly installed on the output shaft of the rotary motor, and a plurality of massage balls are installed on the rotary disk.

[0011] As a further solution of the present invention: the heights of the multiple lifting buckets in each section of the double-groove thread are arranged in an S shape.

[0012] As a further solution of the present invention: the heights of the multiple lifting buckets in each section of the double-groove thread are arranged in an increasing manner.

[0013] As a further solution of the present invention: a massage area is formed between the bottom pad and the wave pad, the lifting barrel extends into the massage area, and a central airbag is installed at the center of the massage area.

[0014] Beneficial effects of the present invention: The present invention measures the size of local pressure through a pressure sensor. When the pressure in one area is high, the air source and the control valve are opened to inflate the local airbag, thereby adjusting the pressure and improving the comfort level. The invention is highly intelligent and adaptable, and the inflation of the airbag is controlled individually through each control valve, which is more accurate.

[0015] The present invention can heat the wave pad by arranging the heating rod, thereby preventing the wave pad from getting wet and reducing moisture.

[0016] The cam of the present invention lifts the lifting barrel as it moves, and the massage balls then massage the body. The cam is symmetrically arranged, and the two sections of double-groove threads are also symmetrically arranged. In other words, the cam moves from both sides toward the center, which in turn drives the massage balls to continuously lift from both sides toward the center, thus massaging the body. This can reduce the risk of acquired pressure injuries during surgery. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1-3 As shown, the present invention is a body positioning pad used during surgery to prevent acquired pressure injuries during surgery, comprising a base pad 1, a wave pad 2 being provided on the top of the base pad 1, the wave pad 2 being a hollow structure, and the wave pad 2 being made of skin-friendly and breathable material, and being more comfortable to use, a plurality of sealing pads 26 being provided inside the wave pad 2, and the sealing pads 26 forming the wave pad 2 into a plurality of airbag placement areas 25, each of the airbag placement areas 25 being provided with an airbag 211 and a heating rod 23, and the setting of the heating rod 23 can heat the wave pad 2 to prevent it from getting wet and reduce moisture; the airbag 211 is connected to the airbag inflation port 28 opened on the wave pad 2, and the airbag inflation port 28 is connected to the air source 29 through a hose, and each of the hoses is installed with a control valve 210.

[0023] The provision of multiple airbags 211 is intended to be designed for different people. Each person has different circumstances, so the position where the airbag 211 needs to be inflated is also different, making it more adaptable.

[0024] The wave pad 2 is embedded with a pressure sensor 22, which is used to measure the pressure values ​​of different areas of the wave pad 2, and then transmit the pressure value signal to the controller, which controls the air source 29 and the control valve 210 to open and inflate. Due to different postures of people, they will be subjected to different forces. If the forces are different for a long time, the part with high pressure will easily form an acquired pressure injury during surgery. Therefore, the pressure sensor 22 is used to measure the local pressure. When the pressure in one area is high, the air source 29 and the control valve 210 are opened to inflate the local airbag 211, thereby adjusting the pressure and improving its comfort. In addition, it is highly intelligent and adaptable. Each control valve 210 is used to individually control the inflation of the airbag 211, which is more accurate.

[0025] The wave pad 2 is provided with a plurality of through holes 21 to facilitate heat dissipation.

[0026] Example 2

[0027] Based on Example 1, please refer to Figure 4-5As shown, a driving motor 31 is fixedly installed inside the base pad 1, and a driving wheel 32 is fixedly installed on the output shaft of the driving motor 31; a plurality of driven wheels 33 and a balancing wheel 34 are arranged in an array inside the base pad 1, and a belt is sleeved on the driving wheel 32, the driven wheel 33 and the balancing wheel 34, and the belt is wrapped around the driven wheel 33 in an S shape; a threaded rod 35 is fixedly installed on the driven wheel 33, and the threaded rod 35 is provided with multiple sections of double-groove threads, and a cam 310 is sleeved on the threaded rod 35; a plurality of lifting barrels 36 are arranged in an array above the threaded rod 35, and connecting blocks 39 are fixedly installed on both sides of the lifting barrel 36, and a guide column 37 is inserted at the bottom of the connecting block 39, and a spring 38 is sleeved on the guide column 37, and the lifting barrel 36 is rotatably connected to the massage ball 313.

[0028] The driving motor 31 is started to drive the driving wheel 32 to rotate. The driving wheel 32 drives multiple driven wheels 33 and a balance wheel 34 to rotate through a belt. The driven wheel 33 drives the threaded rod 35 to rotate. The threaded rod 35 drives the cam 310 to move back and forth. During the movement of the cam 310, the lifting barrel 36 is lifted, and then the massage ball 313 is used to massage the human body. Figure 4 It is obvious that the cam 310 is symmetrically arranged, and the two sections of double-groove threads are also symmetrically arranged. In other words, the cam 310 moves from both sides to the center, which in turn drives the massage balls 313 to continuously push up from both sides to the center for massage. This will reduce the occurrence of acquired pressure injuries during surgery.

[0029] A rotary motor 311 is fixedly mounted inside the lifting barrel 36. A rotating disk 312 is fixedly mounted on the output shaft of the rotating motor 311. A plurality of massage balls 313 are mounted on the rotating disk 312. When the rotating motor 311 is activated, the rotating disk 312 and the massage balls 313 rotate, thereby achieving a more effective massage effect while the massage balls 313 are rotating during the lifting massage process.

[0030] The height of the multiple lifting buckets 36 of each double-groove thread is S-shaped. The height of the multiple lifting buckets 36 of each double-groove thread is incrementally arranged, which is modified according to actual conditions, either S-shaped massage or incremental massage.

[0031] A massage area 27 is formed between the base pad 1 and the wave pad 2. The lifting barrel 36 extends into the massage area 27, and a central airbag 24 is installed at the center of the massage area 27. The inflation of the central airbag 24 is also carried out according to our actual needs. Due to the setting of the lifting barrel 36 and the screw rod 35, there will definitely be a depression in the middle. Sometimes it may be necessary to lift it up, and sometimes it may not be necessary. Therefore, the central airbag 24 is needed for support to play a role of adjustment.

[0032] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
