Pillow

Abstract

The utility model relates to a pillow. The pillow comprises a neck pillow part and a fixing part. The neck pillow part extends in the first direction and is used for fixing the neck. The fixing part extends in a second direction different from the first direction and is connected with the neck pillow part. The number of the fixing parts is two. The two fixing parts are distributed in the first direction so that a head fixing space of the pillow can be formed between the two fixing parts. According to the pillow, the neck of a patient is allowed to make contact with the neck pillow part, the head is contained in the head fixing space, and the shoulders can abut against the side, away from the fixing part, of the neck pillow part. By means of the arrangement, the head of a patient is fixed through the fixing parts on the two sides, and the problem that a tracheal catheter and a venous catheter slip off due to shaking of the head of the patient in the first direction in the operation process is solved. Meanwhile, the neck pillow part can provide support for the neck of the patient, the situation that spinal nerve roots are pressed and neck muscles and ligaments are too nervous due to the hyperextension body position of the neck is avoided, and then the situation that blood backflow under the neck and vertebral artery blood flow are affected is avoided.

Description

Technical Field

[0001] The present application relates to the field of medical devices, and particularly to a pillow. Background Art

[0002] Thyroid surgery is one of the important means to solve thyroid space-occupying lesions. During the surgery, the patient needs to adopt a neck hyperextension position, making the patient's mandible, trachea, and sternum close to a straight line to fully expose the surgical field for the convenience of the surgery. The neck hyperextension position often compresses the vertebral artery passing through the transverse foramen of the cervical vertebra. The compression or spasm of the vertebral artery causes blood flow obstruction, resulting in cerebral ischemia, and thus the patient shows symptoms such as dizziness, headache, nausea, and vomiting after the surgery. And the proportion and severity of these symptoms increase with the prolongation of the duration of the neck hyperextension position.

[0003] For endoscopic thyroid surgery, it is required that the surgical field be fully exposed. When placing the traditional supine surgical position, the patient's head needs to be tilted backward, and at the same time, the neck is stretched to facilitate the exposure of the field of view. It is necessary to place multiple appropriate position pads on the head and shoulders to achieve the effects of exposing the field of view and fixing the patient. Therefore, this position placement requires multiple people to cooperate simultaneously for many times, which takes a long time. At the same time, during the placement process, it is necessary to swing the head and neck, which is likely to cause the slippage of the tracheal catheter and venous catheter. During the surgery, the neck hyperextension position is extremely likely to cause compression of the spinal nerve roots, and the neck muscles and ligaments are too tense, affecting the blood return in the neck and the blood flow of the vertebral artery, making the brain tissue in a transient ischemic state, thus showing symptoms such as dizziness, nausea, and vomiting.

[0004] Traditional position pads have fixed specifications, rigid materials, and poor resilience. When placing them, multiple people, multiple times, and multiple position pads are required, and the operation is cumbersome. They are prone to sliding under external force, resulting in a change in position. In addition, they cannot meet the needs of patients with different body types to fully expose the surgical field without excessive neck hyperextension. More and more studies have shown that using position pads or performing modified positions during thyroid surgery can better reduce the discomfort symptoms such as nausea and vomiting in patients after the surgery.

[0029] Here, the technical solutions in the embodiments (or "embodiment modes") of the present application will be clearly and completely described in conjunction with the drawings. When the following description involves the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] If there are terms related to directional indication or positional relationship in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial direction, radial direction, circumferential direction, etc.), such terms are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, terms such as "first" and "second" in the embodiments of the present application are only used for the purpose of description convenience and should not be construed as indicating or implying relative importance.

[0031] Reference Figure 1 and Figure 2 According to the present application, a pillow 100 is provided. The pillow 100 includes a neck support portion 1 and a fixing portion 2. The neck support portion 1 extends along a first direction X and is used for fixing the neck. The fixing portion 2 extends along a second direction Y different from the first direction X and is connected to the neck support portion 1. Among them, there are two fixing portions 2. The two fixing portions 2 are distributed along the first direction X to form a head fixing space 3 of the pillow 100 between the two fixing portions 2.

[0032] When using the pillow 100 of the present application, the patient's neck contacts the neck support portion 1, the head is received in the head fixing space 3, and the shoulders can abut against the side of the neck support portion 1 away from the fixing portion 2. By such a setting, the patient's head is fixed by the fixing portions 2 on both sides, avoiding the problem of slippage of the tracheal catheter and venous catheter caused by the shaking of the patient's head in the first direction X during the operation. At the same time, the neck support portion 1 can provide support for the patient's neck, avoiding the problems of compression of the spinal nerve roots, over-tension of the neck muscles and ligaments caused by the neck hyperextension position, and further affecting the blood return in the neck and the blood flow of the vertebral artery. Therefore, it can effectively relieve the patient's symptoms such as dizziness, nausea, and vomiting.

[0033] It should be noted that the present application sets the first direction X, the second direction Y, and the height direction Z as reference directions. And the first direction X is correspondingly shown as the width direction of the pillow 100 in the drawings, and the second direction Y is correspondingly shown as the length direction of the pillow 100 in the drawings. The first direction X, the second direction Y, and the height direction Z are shown as perpendicular to each other in the drawings. However, this should be regarded as illustrative rather than restrictive. The included angles between the first direction X, the second direction Y, and the height direction Z can be the same or different, and can also present any angle other than a right angle. The present application does not limit this.

[0034] In order to improve the comfort and fixation of the cervical pillow 1, in some embodiments, the cervical pillow 1 includes an arc-shaped upper surface 11. The arc-shaped setting allows the cervical pillow 1 to better fit the shape of the human neck, improves the comfort of the patient when leaning on the pillow 100, and avoids the sharp corner structure from excessively compressing the nerves and causing discomfort. In addition, the cervical pillow 1 also includes a recessed unit 12 that is recessed downward from the upper surface 11. The recessed unit 12 is used to fix the neck. By providing the recessed unit 12, when the patient's neck contacts the cervical pillow 1, the part of the cervical pillow 1 other than the recessed unit 12 can prevent the neck from swinging in the first direction X. It can be seen that through the cooperation of the recessed unit 12 and the two fixing parts 2, the pillow 100 can provide the patient with stable neck and head support and reduce the probability of postoperative discomfort.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the recessed unit 12 is centrally arranged on the upper surface 11 in the first direction X. The central arrangement of the recessed unit 12 can more reasonably utilize the space of the pillow 100. For example, the central arrangement of the recessed unit 12 allows the fixing parts 2 to be symmetrically arranged on both sides of the recessed unit 12, thereby avoiding the waste of space of the cervical pillow part 1 that does not contact the neck. Even in the embodiment where the fixing parts 2 on both sides are asymmetrically arranged, the central arrangement of the recessed unit 12 can also enable the patient's shoulders on both sides to be symmetrically contacted and supported, thereby improving comfort.

[0036] refer to Figure 1 In some embodiments, the recessed depth H1 of the recessed unit 12 is greater than or equal to 0.8 cm and less than or equal to 1.5 cm. For example, the recessed depth H1 can be 0.8 cm, 0.9 cm, 1.0 cm, 1.1 cm, 1.2 cm, 1.3 cm, 1.4 cm, 1.5 cm or any value therebetween. The recessed depth H1 enables the cervical pillow portion 1 on both sides of the recessed unit 12 to provide sufficient fixing force for fixing the neck and prevent the neck from shaking in the first direction X. In addition, it is easy to understand that the cervical pillow portion 1 needs to have sufficient thickness at the recessed unit 12 to provide neck support. If the recessed depth H1 is too large, the support of the recessed unit 12 is insufficient. It can be seen that the range of the recessed depth H1 can balance the neck support effect and the neck fixation effect.

[0037] refer to Figure 2, in some embodiments, the size L1 of the concave unit 12 in the first direction X is greater than or equal to 8 cm and less than or equal to 12 cm. For example, the size L1 can be 8 cm, 9 cm, 10 cm, 11 cm, 12 cm or any value therebetween. If the size L1 of the concave unit 12 in the first direction X is too large, it is difficult to provide the function of restricting neck swing. If the size of the concave unit 12 in the first direction X is too small, the comfort level for patients with a larger body size will be too low. The size L1 within this range can adapt to the neck sizes of the vast majority of patients, thereby providing good support ability and improving the comfort level when using the pillow.

[0038] In some embodiments, the size L2 of the neck pillow part 1 in the first direction X is greater than or equal to 38 cm and less than or equal to 42 cm. For example, the size L2 of the neck pillow part 1 in the first direction X can be 38 cm, 39 cm, 40 cm, 41 cm, 42 cm or any value therebetween. If the neck pillow part 1 is too long, it not only wastes materials but also takes up a large amount of space, which is not conducive to storage management. If the neck pillow part 1 is too short, it is difficult to adapt to the shoulder widths of patients with different body sizes, and it is difficult to provide good support for patients with wider shoulders. The size L2 within this numerical range can balance the volume and support performance of the neck pillow part 1.

[0039] In an alternative embodiment, the size W1 of the neck pillow part 1 in the second direction Y is greater than or equal to 10 cm and less than or equal to 13 cm. For example, the size W1 of the neck pillow part 1 in the second direction Y can be 10 cm, 10.5 cm, 11 cm, 11.5 cm, 12 cm, 12.5 cm, 13 cm or any value therebetween. The W1 within this numerical range can adapt to the neck lengths of most patients and provide good and comfortable neck support for patients.

[0040] Reference Figure 1 , the size H2 of the neck pillow part 1 in the height direction Z also has an important impact on the comfort level that the neck pillow part 1 can provide. If the neck pillow part 1 is too high, an excessive neck hyperextension posture is likely to cause discomfort to the patient. If the neck pillow part 1 is insufficient, the exposure of the surgical field is not sufficient. In some embodiments, the size H2 of the neck pillow part 1 in the height direction Z is greater than or equal to 10 cm and less than or equal to 12 cm. The size H2 can be, for example, 10 cm, 10.5 cm, 11 cm, 11.5 cm, 12 cm or any value therebetween. The size H2 within this numerical range can fully expose the surgical field without causing excessive neck hyperextension of the patient.

[0041] In various embodiments of the present application, the neck pillow portion 1 can be configured as a polyurethane slow-rebound sponge neck pillow. In other words, the neck pillow portion 1 is made of memory sponge material. The polyurethane slow-rebound sponge material has the ability of memory deformation and strong automatic shaping ability, which can evenly distribute the pressure of the whole body and prevent the patient's neck from being suspended in the air. In addition, the polyurethane slow-rebound sponge neck pillow can adjust itself and fit closely to the neck according to the different neck lengths and body shapes of different patients, which is conducive to avoiding the state of neck suspension, supporting and protecting the cervical spine, and avoiding neck discomfort in patients. The polyurethane slow-rebound sponge material has a certain hardness, which is convenient for medical staff to move and place, and improves the success rate of medical staff in placing the surgical position in one time, thereby significantly improving the satisfaction of surgeons and patients.

[0042] In order to further improve the adaptability of the pillow 100 to different patients, in some embodiments, the fixing part 2 is fixedly connected to the cervical pillow part 1, and the fixing part 2 is a flexible fixing part 2. The fixing part 2 can be a sandbag filled with granular materials such as sand, or it can be a cotton bag filled with cotton. The provision of the flexible fixing part 2 enables the fixing part 2 to be adaptively deformed according to the shape and size of the patient's head, while not applying excessive elastic force to the patient to cause discomfort to the patient's head. The fixing part 2 is fixedly connected to the cervical pillow part 1, which can improve the strength of the flexible fixing part 2 to a certain extent, so that the fixing part 2 can well fix the patient's head even if it is deformed.

[0043] In some optional embodiments, the fixing portion 2 includes a connecting unit 21 and a fixing unit 22. One end of the connecting unit 21 is connected to the cervical pillow portion 1, and the other end is connected to the fixing unit 22. Among them, the cross-sectional area of the connecting unit 21 is smaller than the cross-sectional area of the fixing unit 22. The connecting unit 21 with a small cross-sectional area has a high deformability, which facilitates the swing of the fixing unit 22. The fixing unit 22 with a large cross-sectional area can provide good support for the patient's head. By setting different cross-sectional areas for the fixing portion 2 at different positions, the fixing portion 2 can provide different functions in a targeted manner, which is conducive to improving the use experience of medical staff.

[0044] In some embodiments, in the second direction Y, the cross-sectional area of the fixing unit 22 first decreases and then increases. The change in cross-sectional area can improve the deformation ability of the fixing unit 22, so as to adapt to the head shapes and head sizes of different patients and provide good fixed support. The change in cross-sectional area of the fixing unit 22 of the pillow 100 in the accompanying drawings is shown to be symmetrical in the second direction Y, that is, the cross-sectional area becomes smaller in the middle position of the second direction Y and then increases. However, in other embodiments, the position of the change in cross-sectional area can also be closer to the cervical pillow portion 1, or further away from the cervical pillow portion 1. The present application is not limited to this.

[0045] like Figure 2As shown, in some embodiments, the dimension W2 of the fixing unit 22 in the second direction Y is greater than or equal to 21 cm and less than or equal to 25 cm. For example, the dimension W2 of the fixing unit 22 in the second direction Y can be 21 cm, 22 cm, 23 cm, 24 cm, 25 cm or any value therebetween. If the dimension W2 of the fixing unit 22 in the second direction Y is too large, it will cause waste of space; if the dimension W2 is too small, it will be difficult to adapt to the head sizes of patients of different ages, body types and genders in the second direction Y. The fixing unit 22 within this range can provide good head support for different patients.

[0046] In each embodiment, a waterproof cloth bag can be provided on the outer side of the pillow 100. The cloth bag made of waterproof material can well prevent the contamination of body fluids and blood during the operation, and is convenient for medical staff to wipe and disinfect the surface, improving the hygiene of the pillow 100.

[0047] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principle of this application shall be included within the scope of protection of this application.
