Description

Technical Field

[0001] The invention relates to medical instruments, in particular to an axillary pad used for relieving compression of axillary nerves and blood vessels during side-lying surgery. Background Art

[0002] During side-lying surgery, the nerves and blood vessels in the armpit are easily compressed, which can cause many adverse effects on the patient. Traditional surgical auxiliary devices usually lack targeted protection for the axillary nerves and blood vessels, and it is difficult to effectively relieve the compression problem in this area. When the patient lies on his side for a long time, the pressure on the arm and side chest in the axillary area cannot be well dispersed and adjusted, which will not only cause discomfort to the patient and affect the surgical experience, but may even cause damage to the axillary nerves and blood vessels, thereby affecting the safety of the operation and the patient's postoperative recovery. In addition, the traditional device has a relatively simple function in terms of fixation and support, lacks flexibility and adaptability, and cannot be adjusted according to the physical characteristics of different patients. Moreover, problems such as displacement may occur during use, making it difficult to ensure continuous and effective support and protection for the axillary area, and unable to meet the needs of axillary nerve and blood vessel protection and patient comfort in side-lying surgery;

[0003] Based on this, it is necessary to develop a new type of armpit pad to solve these problems. Summary of the invention

[0014] Beneficial effects: The exquisite design of the gas control device is a highlight, which plays a vital role in relieving the compression of the axillary nerves and blood vessels. This device is composed of a series of precision components such as the gas control cavity, the hollow round block, and the rotating column. The components work well together to achieve precise control of the inflation and deflation process of the airbag. The control range of the airbag is precisely set between 5-8 cm. Within this range, the pressure on the axilla can be finely adjusted according to actual needs, which not only avoids the problem of insufficient pressure and ineffective support, but also prevents excessive compression or even damage to the nerves and blood vessels due to excessive pressure. The block and its related accessories, such as the telescopic slot, the locking rod, the reset spring rod, and the wedge-shaped card block, play a key stabilizing role in it. They can firmly lock the rotation angle of the hollow round block to ensure that the gas flow and on-off are precisely controlled. This precise control mechanism effectively prevents the occurrence of accidental gas leakage or pressure fluctuations, and provides reliable stability for the entire gas control process. At the same time, the positioning slot cooperates with the arc block, spring and other structures to further optimize the gas regulation and sealing effect. Through clever design, they avoid various potential risks caused by unstable components, so that the entire gas control device can maintain good performance in complex use environments. The anti-skid pad design in the device is unique. It can effectively prevent the armpit pad from sliding and avoid unnecessary interference to surgical operations due to position deviation.

[0015] In terms of design, the engagement distance of the U-shaped groove is set at about 15cm. This design further enhances the engagement comfort of the side chest, increases the stability and reliability of the entire device, and provides a solid and reliable guarantee for surgical operations. It greatly reduces the risk of surgical accidents caused by axillary pad problems, making the surgical process safer and more stable, and provides strong support for the operation of medical workers. The soft pad on the U-shaped groove is made of soft and elastic materials, such as silicone or soft fabric, which greatly reduces the discomfort and possible skin and tissue damage caused by compression in the patient's armpit during long-term surgery, and provides patients with a comfortable contact experience and buffering protection. The presence of the airbag can adjust the pressure in real time according to the patient's condition to avoid excessive compression, further improving the patient's comfort. In addition, the use of the anti-slip pad ensures the stability of the armpit pad position, avoids the patient's body shaking or additional compression caused by the sliding of the pad, and allows the patient to maintain a side-lying position more comfortably. These designs focus on the patient's feelings from multiple angles. While ensuring the smooth progress of the operation, they provide patients with a more comfortable and reassuring experience during the operation, reducing the physical and psychological burden caused by the armpit pad.

DETAILED DESCRIPTION

[0024] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1-7 As shown, an axillary pad for relieving axillary nerve and blood vessel compression during side-lying surgery is provided, comprising a support block 1, a U-shaped groove 2 is provided on the upper surface of the support block 1, storage grooves 3 are symmetrically provided on the upper surface of the U-shaped groove 2, an air bag 4 is fixedly connected inside the storage groove 3, an air inlet cavity 5 is provided on the lower surface of the air bag 4, and an air control device 6 is fixedly connected to the front surface of the support block 1;

[0027] Before the operation, medical staff need to carefully check the various parts of the armpit pad. Confirm that the support block 1 has no cracks or deformation, the U-shaped groove 2 and the storage groove 3 are not damaged, the airbag 4 has no air leakage, and the air control device 6 functions normally. The air control device 6 is tightly connected to the air inlet cavity 5 of the airbag 4. According to factors such as the patient's body shape and the expected duration of the operation, the airbag 4 is adjusted to a suitable initial state through the air control device 6. During the operation, after the patient lies on his side, the medical staff will accurately place the armpit pad under the patient's armpit so that the U-shaped groove 2 fits the contour of the armpit. During the operation, the medical staff will inflate or deflate the airbag in real time through the air control device based on the patient's feedback if the patient is awake or observes the skin condition of the armpit. If the local pressure in the armpit is high and the skin is abnormal, the airbag will be inflated through the air control device; if the patient feels bloated and uncomfortable, the air control device will be deflated to reduce pressure. Under the control of the air control device, the airbag cooperates with the support block to provide stable support for the armpit. After the operation, the air in the airbag is first emptied through the air control device to facilitate the removal of the armpit pad. Afterwards, clean and disinfect the armpit pad, using appropriate cleaning agents and disinfection methods to ensure that all parts are sterile for next use;

[0028] In terms of design, the soft pad on the U-shaped groove is made of soft and elastic materials, such as silicone or soft fabric, which greatly reduces the discomfort and possible skin and tissue damage caused by compression in the patient's armpits during long operations, and provides patients with a comfortable contact experience and cushioning protection. The presence of the airbag can adjust the pressure in real time according to the patient's condition to avoid excessive compression, further improving the patient's comfort. Furthermore, the use of anti-slip pads ensures the stability of the armpit pad position, avoids the patient's body shaking or additional compression caused by the sliding of the pad, and allows the patient to maintain a side-lying position more comfortably. These designs focus on the patient's feelings from multiple angles. While ensuring the smooth progress of the operation, they provide patients with a more comfortable and reassuring experience during the operation, reducing the physical and psychological burden caused by the armpit pad.

[0043] In this embodiment, the air control device 6 includes an air control cavity 7, a circular groove 8 is provided inside the air control cavity 7, a rotating column 9 is fixedly connected inside the circular groove 8, a limiting disk 10 is fixedly connected to the front surface of the rotating column 9, a hollow round block 11 is rotatably connected inside the circular groove 8, a rotating groove 12 is provided on the rear surface of the hollow round block 11, the inner side wall of the rotating groove 12 is rotatably connected to the outer side wall of the rotating column 9, an air outlet hole 30 is symmetrically provided on the inner side wall of the circular groove 8, an air outlet cavity 13 is fixedly connected to the outer side wall of the hollow round block 11, an air outlet long tube 14 is fixedly connected to the inner side of the air outlet hole 30, and an air outlet hole 30 is fixedly connected to the inner side of each of the air outlet holes 30. One end of the long air tube 14 away from the air outlet 30 penetrates into the interior of the support block 1 and is fixedly connected with the adjacent air outlet cavity 13. A turning port 16 is provided on the front surface of the air control cavity 7. An air inlet pipe 15 is fixedly connected to the front surface of the hollow circular block 11. The front end of the air inlet pipe 15 penetrates into the front surface of the air control cavity 7 and is rotatably connected to the inner side of the turning port 16. The outer wall of the air inlet pipe 15 is located in front of the air control cavity 7 and is fixedly connected with a locking block 17. A plurality of locking holes 18 are symmetrically provided on the front surface of the air control cavity 7. An air blocking block 31 is fixedly connected to the outer wall of the hollow circular block 11.

[0044] The air control device 6 is of vital importance in the armpit pad. It includes an air control cavity 7, in which a rotating column 9 is arranged in a circular groove 8, and a limiting plate 10 on the front surface of the rotating column 9 ensures the stability of the device. The hollow circular block 11 rotates in the circular groove 8, and its rotating groove 12 is connected to the outer wall of the rotating column 9. The air outlet hole 30 of the circular groove 8 is connected to the long air outlet tube 14, which passes through the support block 1 and is connected to the air outlet cavity 13. The air inlet pipe 15 of the hollow circular block 11 is rotatably connected in the rotating port 16 of the air control cavity 7, and the locking block 17 on the air inlet pipe 15 can be inserted into a locking hole 18 on the front surface of the air control cavity 7 to fix the rotation angle of the hollow circular block 11 and control the gas flow and on-off. At the same time, the air blocking block 31 on the outer wall of the hollow circular block 11 will block the air outlet 30 to varying degrees during rotation. In this way, the air control device 6 can accurately control the inflation and deflation of the airbag 4 through the coordination of various components, accurately adjust the airbag pressure during the operation, effectively relieve the compression of the axillary nerves and blood vessels, and ensure the smooth progress of the operation.

[0045] In this embodiment, a telescopic groove 19 is formed on the rear surface of the locking block 17, a locking rod 20 is slidably connected inside the telescopic groove 19, a reset spring rod 21 is fixedly connected to the front surface of the locking rod 20 and the inner side wall of the telescopic groove 19, and a wedge-shaped block 22 is fixedly connected to the rear end of the locking rod 20;

[0046] The locking block 17 is an important component in the air control device 6, and a telescopic groove 19 is provided on its rear surface. Inside the telescopic groove 19, a locking rod 20 is slidably connected. The locking rod 20 is not fixed, and it can slide in the telescopic groove 19 to achieve different locking functions. A reset spring rod 21 is fixedly connected between the front surface of the locking rod 20 and the inner side wall of the telescopic groove 19. The function of the reset spring rod 21 is to provide a reset elastic force for the locking rod 20. When the external force applied to the locking rod 20 disappears, the locking rod 20 can return to the initial position under the elastic force of the reset spring rod 21. The rear end of the locking rod 20 is fixedly connected to a wedge-shaped block 22. The wedge-shaped block 22 has a unique shape, and its wedge-shaped structure helps to cooperate with the locking hole 18. When the rotation angle of the hollow circular block 11 needs to be locked, the wedge-shaped block 22 will be inserted into the corresponding locking hole 18 to achieve the locking function. Due to the wedge-shaped design, the wedge-shaped block 22 can be inserted and removed from the locking hole 18 more smoothly, and can provide a relatively stable locking effect, preventing the hollow round block 11 from rotating accidentally, and ensuring the precise control of the gas flow and on-off by the gas control device 6. In this way, through the coordinated work of the locking block 17 and its auxiliary components, the operation of the gas control device 6 is made more flexible and reliable, providing a more sophisticated guarantee for the stable use of the armpit pad during surgery.

[0047] In this embodiment, a positioning groove 23 is provided on the inner upper surface of the circular groove 8;

[0048] A positioning groove 23 is provided on the inner upper surface of the circular groove 8 of the gas control device 6. The positioning groove 23 is used to position the gas outlet cavity 13 in the circular groove 8 and fix it when gas control is not required to prevent gas from leaking out.

[0049] In this embodiment, a spring slot 24 is provided on the right side of the air outlet cavity 13, an arc block 25 is slidably connected inside the spring slot 24, a wedge-shaped hollow tube 26 is fixedly connected to the right side of the arc block 25, and a plurality of springs 27 are fixedly connected between the left side of the arc block 25 and the inner side wall of the spring slot 24;

[0050] On the right side of the air outlet cavity 13, there is a spring slot 24. The spring slot 24 is a special structure that provides sliding space for subsequent components. An arc block 25 is slidably connected inside the spring slot 24. The arc block 25 can slide freely in the spring slot 24, so that its position can be adjusted according to different working conditions. The right side of the arc block 25 is fixedly connected to a wedge-shaped hollow tube 26, which can be engaged with different air outlet holes 30. At the same time, a plurality of springs 27 are fixedly connected between the left side of the arc block 25 and the inner side wall of the spring slot 24. The function of these springs 27 is to provide elastic support for the arc block 25. When the arc block 25 is subjected to external force, the spring 27 will undergo elastic deformation and store elastic potential energy; when the external force disappears, the spring 27 will release the elastic potential energy and push the arc block 25 back to its original position, so that the air outlet cavity 13 can contact different air outlet holes 30.

[0051] In this embodiment, a non-slip pad 28 is fixedly connected to the lower surface of the support block 1;

[0052] The lower surface of the support block 1 is fixedly connected with an anti-skid pad 28. The main function of the anti-skid pad 28 is to increase the friction between the support block 1 and the placement plane such as the operating table to prevent the armpit pad from accidentally sliding during use. During the operation, the patient is in a side-lying state, and the weight of the body will be partially applied to the armpit pad, and a certain amount of external force interference may be generated due to the surgical operation. Without the anti-skid pad 28, the support block 1 may be displaced on the operating table, affecting the position stability of the armpit pad, and further affecting its effect of relieving compression of the axillary nerves and blood vessels.

[0053] In this embodiment, a soft pad 29 is fixedly connected to the upper surface of the U-shaped groove 2;

[0054] A soft pad 29 is fixedly connected to the upper surface of the U-shaped groove 2. The main function of the soft pad 29 is to provide a more comfortable contact experience for the patient, and it can also play a certain buffering and protective role. During the operation, the patient's armpit is in direct contact with the U-shaped groove 2. Due to long-term compression, the patient's skin and armpit tissue may be uncomfortable or even damaged. The presence of the soft pad 29 can alleviate this sense of oppression and reduce the friction and pressure on the patient's skin and tissue. It can be made of soft, comfortable and elastic materials, such as silicone or soft fabric.

[0055] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
