Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary products technology, specifically to an inflatable neck and shoulder support pad. Background Technology

[0002] The jugular vein is an important deep vascular system in the neck, responsible for returning blood from the head and neck to the heart. It mainly consists of the superficial external jugular vein and the deep internal jugular vein. The internal jugular vein has a large diameter and, after originating from the jugular foramen at the base of the skull, descends along the lateral side of the common carotid artery within the carotid sheath, eventually joining the subclavian vein behind the sternoclavicular joint to form the brachiocephalic vein. Due to its relatively fixed course and large lumen, it is the preferred route for central venous catheterization, long-term intravenous infusion, and hemodynamic monitoring.

[0003] Exposing the jugular vein is a crucial step in clinical puncture or surgery, aiming to provide a clear path and stable field of vision for the procedure. The standard clinical position requires the patient to lie supine with the head pillow removed, head fully tilted back and turned to the opposite side to extend the neck. This position makes the sternocleidomastoid muscle landmark more prominent, aiding in the location and exposure of the jugular vein. To maintain this position, medical staff often place a soft pillow or special foam pad under the patient's shoulder to keep the neck extended; simultaneously, sandbags or soft pillows are used on the sides of the head and neck for fixation to prevent head rotation. However, using soft pads or foam pads presents several problems: their fixed height makes it difficult to achieve precise individual support. If the pad is placed too high, it can lead to excessive neck extension, potentially compressing the jugular vein and affecting blood return efficiency, while also increasing patient discomfort and airway management difficulties. If the pad is placed too low, it cannot maintain a stable neck posture during prolonged surgery, potentially causing changes in the target vessel's position. Furthermore, the support effectiveness of these pads is highly dependent on the operator's experience; even slight deviations in placement can affect support stability.

[0004] Therefore, how to design an inflatable neck and shoulder support pad that can be flexibly adjusted according to individual patient differences and provide continuous and stable support is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the technical defects in the prior art where it is difficult to achieve individualized and precise support by using soft pads or foam pads. If the pad is placed too high, it will easily compress the jugular vein and affect blood return. If it is placed too low, it will be difficult to provide stable support for a long time, which will lead to changes in the position of the target blood vessels. Thus, an inflatable neck and shoulder support pad that can be flexibly adjusted according to the individual differences of patients and provide continuous and stable support is provided.

[0088] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0089] This embodiment provides an inflatable neck and shoulder support pad, such as Figure 1-3 As shown, it includes: a head support pad 1, a neck support pad 4, an inflatable structure, and an installation structure; wherein, the head support pad 1 includes a head support base 2 and a head support soft pad 3 that is adjustablely mounted on top of the head support base 2, the head support soft pad 3 having a first inner cavity suitable for wearing on the patient's head; the neck support pad 4 includes a neck support base 41 and a neck support soft pad 42 fixedly connected to the top of the neck support base 41, the neck support soft pad 42 having a second inner cavity suitable for placing under the patient's neck; the inflatable structure is used to inflate or deflate the first inner cavity or the second inner cavity, causing the head support soft pad 3 or the neck support soft pad 42 to inflate or deflate back to its original shape; the installation structure is used to fix the head support base 2 and the neck support base 41.

[0090] When used on patients requiring full exposure of the jugular vein, the head support base 2 and neck support base 41 are first fixed in the appropriate position using the mounting structure. Then, a certain amount of gas is pre-inflated into the head support cushion 3 and neck support cushion 42 using the inflation structure. After inflation, the head support cushion 3 is placed on the back of the patient's head, and the neck support cushion 4 is placed under the patient's neck. The angle of the head support cushion 3 is then adjusted so that the patient's head turns to the opposite side to achieve neck extension. After adjustment, the head support cushion 3 and neck support cushion 42 are inflated again using the inflation structure according to the patient's actual condition, so that they expand and stably support the patient's head and neck. Compared with using soft pads or foam pads to support the head and neck, which are prone to problems such as neck hyperextension or support failure due to padding too high or too low, and are highly dependent on operating experience, the inflatable neck and shoulder support cushion of this embodiment can flexibly adjust the support height and shape according to the patient's needs, maintaining positional stability while achieving effective neck extension and avoiding intraoperative displacement, thus providing a more reliable and comfortable operating basis for jugular vein exposure.

[0091] It also includes a neck support airbag 5, which has a third inner cavity. The bottom of the airbag is fixedly connected to the top of the neck support base 41, and the top is fixedly connected to the bottom of the neck support cushion 42. The inflation structure can inflate or deflate the third inner cavity, causing the neck support airbag 5 to expand or deflate back to its original shape. The design of this neck support airbag 5 specifically considers the support needs of rickets patients. Since the neck of rickets patients is usually positioned higher, during use, air can be inflated into the neck support airbag 5 through the inflation structure, causing it to expand and lift the neck support cushion 42, thus allowing it to fit closely to the patient's neck and provide effective support.

[0092] like Figure 2-3 As shown, the head support cushion 3 is installed at an adjustable angle on the top of the head support base 2 via an adjustable structure; the adjustable structure includes a first tooth 31 and a second tooth 32, wherein there are several first teeth 31, which are uniformly formed on the top of the head support base 2; there are several second teeth 32, which are uniformly formed on the bottom of the head support cushion 3; the second teeth 32 can engage with the first teeth 31 at different positions, thereby allowing the head support cushion 3 to be installed at an adjustable angle on the top of the head support base 2.

[0093] The head support cushion 3 includes a cushion base 33 and a head cushion 35. The cushion base 33 has adjustment handles 34 at both ends. These handles allow the head support cushion 3 to be lifted, disengaging the first and second teeth. After adjusting the angle, it is lowered, and the first and second teeth at corresponding positions are engaged, thus adjusting the installation angle of the head support cushion 3 on the top of the head support base 2. The second tooth 32 is formed at the bottom of the cushion base 33. The head cushion 35 is fixedly connected to the top of the cushion base 33, with the first inner cavity formed inside. The head cushion 35 is suitable for wearing on the patient's head. When adjusting the patient's head angle, medical personnel hold the adjustment handles 34 on both sides of the cushion base 33, lift the cushion base 33, place it in the appropriate position, and engage it with the first tooth 31. Through the engagement of the second tooth 32 with the first tooth 31, the cushion angle can be finely adjusted and automatically fixed at the target position.

[0094] The head cushion 35 is fixedly connected to the top of the cushion base 33 via a connecting structure. The connecting structure includes a concave adhesive surface 36 and a convex adhesive surface 37. The concave adhesive surface 36 is formed on the top of the cushion base 33, and the convex adhesive surface 37 is formed on the bottom of the head cushion 35. The convex adhesive surface 37 can be matched and bonded to the concave adhesive surface 36. The structure also includes connecting slots 38 and connecting blocks 39. There are several connecting slots 38 formed on the top of the cushion base 33. There are several connecting blocks 39 fixedly connected to the bottom of the head cushion 35. When the convex adhesive surface 37 is bonded to the concave adhesive surface 36, the connecting blocks 39 are installed into the connecting slots 38 and bonded to the connecting slots 38.

[0095] like Figure 1 , 4As shown in Figure 7, the inflatable structure includes a first inflation tube 6, a three-way valve 7, a second inflation tube 61, a third inflation tube 62, a first handheld airbag 63, and a first one-way valve 8.

The three-way valve 7 includes a first connecting tube 71, a second connecting tube 72, and a third connecting tube 73 that communicate with each other. The first connecting tube 71 is connected to the other end of the first inflation tube 6. One end of the second inflation tube 61 is fixedly connected to the neck support cushion 42 and extends into the second inner cavity, while the other end is connected to the second connecting tube 72. One end of the third inflation tube 62 is connected to the third connecting tube 73. The first handheld airbag 63 is elastically deformable, has a first inflation chamber, and a first air inlet and a first air outlet communicating with the first inflation chamber. The first air outlet is connected to the third inflation tube 8. The other end of tube 62 is connected for inflating the third inflation tube 62; there are two first one-way valves 8, which are respectively fixedly installed on the first air inlet end and the first air outlet end of the first handheld airbag 63; the first one-way valve 8 installed on the first air inlet end is used to allow only external gas to enter the first inflation chamber from the first air inlet end, and the first one-way valve 8 installed on the first air outlet end is used to allow only the gas entering the first inflation chamber to enter the third inflation tube 62 through the first air outlet end; it also includes a first vent hole 64 and a first vent bolt 65; wherein, the inner wall of the first vent hole 64 has a first internal thread, which is opened on the third inflation tube 62 near the first handheld airbag 63 and communicates with the inner cavity of the third inflation tube 62; the first vent bolt 65 can be sealed and screwed to the first vent hole 64 for releasing air and depressurizing. When inflating the first or second inner cavity, first operate the three-way valve 7 to select the target inner cavity (head or neck), then repeatedly squeeze the first hand-held airbag 63. As the airbag rebounds, it draws in outside air through the first one-way valve 8 at the first air inlet end. When compressed, it enters the third inflation tube 62 through the first one-way valve 8 at the first air outlet end, and then is guided by the three-way valve 7 into the designated inner cavity, causing it to gradually inflate. During this process, the one-way valve effectively prevents gas backflow, ensuring that all airflow is injected unidirectionally into the target inner cavity. When deflation is required, loosening the first deflation bolt 65 outwards opens the first deflation hole 64, allowing gas to escape through it, achieving controlled deflation.

[0096] like Figure 1 , 8As shown, it also includes a fourth inflation tube 66, a second handheld airbag 67, and a second one-way valve 81; wherein, one end of the fourth inflation tube 66 is fixedly connected to the neck support cushion 42 and extends into the third inner cavity; the second handheld airbag 67 is elastically deformable, has a second inflation chamber, and a second air inlet and a second air outlet communicating with the second inner cavity, the second air outlet communicating with the other end of the fourth inflation tube 66 for inflating the fourth inflation tube 66; there are two second one-way valves 81, which are respectively fixedly installed on the second air inlet and the second air outlet of the second handheld airbag 67; the valve installed on the second air inlet... The second one-way valve 81 allows only external gas to enter the second inflation chamber from the second air inlet. The second one-way valve 81 installed at the second air outlet allows only gas entering the second inflation chamber to enter the fourth inflation tube 66 via the second air outlet. It also includes a second vent hole 68 and a second vent bolt 69. The second vent hole 68 has a second internal thread on its inner wall and is located near the second handheld airbag 67 on the fourth inflation tube 66, communicating with the inner cavity of the fourth inflation tube 66. The second vent bolt 69 can be screwed into the second vent hole 68 for sealing and depressurization. When inflating the third inner cavity, the second handheld airbag 67 is repeatedly squeezed. When the airbag rebounds, it draws in external air through the second one-way valve 81 at the second air inlet. When compressed, it enters the fourth inflation tube 66 through the second one-way valve 81 at the second air outlet, and then enters the third inner cavity, gradually expanding. During this process, the one-way valve effectively prevents gas backflow, ensuring that all airflow is injected unidirectionally into the third inner cavity. When venting is required, loosening the second vent bolt 69 outward will open the second vent hole 68, allowing gas to be discharged through the second vent hole 68, thus achieving controlled venting.

[0097] like Figure 4-5As shown, the three-way valve 7 further includes a valve seat 74, a valve core 76, and a valve cover 79; wherein, the valve seat 74 has a mounting cavity 75 with a top opening; the valve core 76 is rotatably mounted in the mounting cavity 75 through the top opening, and a first inflation channel 77 and a second inflation channel 78 communicating with the first inflation channel 77 are formed in the middle; the valve cover 79 is fixedly connected to the top of the valve core 76, and rotating the valve cover 79 can drive the valve core 76 to rotate in the mounting cavity 75; the top surface of the valve cover 79 is provided with an indicator arrow 80, which is used to indicate the passage; it also includes a limiting insertion hole 9 and a limiting insertion post 91; wherein, the limiting insertion hole 9 is formed on the inner bottom wall of the mounting cavity 75; the limiting insertion post 91 is fixedly disposed at the bottom of the valve core 76, and the valve core 76 is mounted When the valve core 76 enters the mounting cavity 75, the limiting pin 91 is matched and inserted into the limiting hole 9; the valve core 76 is also included with a mounting hole 92 and a mounting block 93; the mounting hole 92 is hexagonal and formed on the top of the valve core 76; the mounting block 93 is hexagonal and fixedly disposed on the bottom of the valve cover 79, and the mounting block 93 can be matched and inserted into the mounting hole 92, thereby fixing the valve cover 79 and the valve core 76 together; the valve core 76 is also included with an annular flange 94 and an annular mounting groove 95; the annular flange 94 is formed on the outer wall of the top opening of the valve seat 74; the annular mounting groove 95 is formed on the inner wall of the valve cover 79, and the annular flange 94 can be installed into the annular mounting groove 95, thereby fixing the valve cover 79 and the valve seat 74 together.
