Description

Technical Field

[0001] The utility model relates to the technical field of medical pillows, in particular to a pillow for correcting cervical vertebra scanning in a lying position. Background Art

[0002] CT technology is becoming more and more popular nowadays and has become a diagnostic tool for many diseases. With the improvement of people's living standards, many people pay more and more attention to their health. People choose CT examination to screen the causes of neck discomfort. However, when the radiologist performs a CT scan of the cervical spine on the patient, the shoulder occlusion distorts the image of the cervical-thoracic junction during the scanning of the human cervical-thoracic junction, which causes the deviation of the diagnosis of the cervical-thoracic junction, including spinal diseases, which seriously affects the diagnosis of the patient. This will prevent the patient from receiving more accurate treatment and cause the disease to be not discovered in time. Although ordinary pillows are placed under the patient's cervical spine, there is no way to adjust the patient's cervical curvature to adapt to the effective drooping of the shoulders to ensure the quality of the examination. Ordinary pillows cannot fix the neck of the examinee. Moreover, some examinees are afraid of shaking during the scanning process, which will cause distortion of the scanned image. Although all CTs currently have a scanning frame for the head, the head placed in the frame can play a certain role in fixing the cervical spine. Since the head frame is higher than the examination bed, the cervical spine of the examinee is in an over-flexed position, and the cervical spine cannot be unfolded normally, which will also affect the imaging diagnosis.

[0003] Due to radiation protection considerations, the examination bed in the CT machine room is generally not placed directly against the wall of the operating room, but is placed at an angle and not parallel to the wall, making it difficult for the examination technician to detect with the naked eye the uneven shoulders of the patient caused by incorrect lying posture.

[0004] Since the lower cervical vertebrae, especially the 6th and 7th cervical vertebrae, are often not clearly displayed due to overlapping shoulder structures, the patient is required to lower his shoulders as much as possible during cervical spine examination. However, this is often difficult to control and the scanned images are often not ideal. Repeated scanning is required, which not only affects work efficiency but also increases the number of times the patient is exposed to radiation.

[0005] At present, most devices that assist cervical spine CT scanning require airbag pressurization or shoulder and chest buckle elastic belts to pull the shoulders of the examinee, which is cumbersome to operate, and some inventions at the end of the elastic belts tie up the examinee's hands, which also increases the discomfort of the examinee. In addition, whether the airbag is adjusted to a moderate height depends entirely on the naked eye observation of the inspector, and there is no uniformity. If it is adjusted simply to cater to the comfort of the examinee, the effect is uneven.

[0006] For example, in the patent document with the patent application number CN201220322623.7 and the name "CT Head Scanning Fixing Pillow", a CT head scanning fixing pillow is disclosed, which belongs to a medical device, and includes a base and a pillow body arranged on the base, characterized in that: the pillow body is divided into a headrest and a neck pillow, trapezoidal fixing plates with fixing belts are arranged on both sides of the headrest, a soft cushion is arranged on the upper surface of the headrest, the neck pillow is a hollow structure, an inflatable tube is arranged on the neck pillow, and an air bag is arranged at the other end of the inflatable tube. This kind of fixing pillow needs to use a fixing belt to tie up the patient, which is easy to cause discomfort to the patient. In addition, the fixing belt and the inflatable bag often need to be adjusted according to the patient's body shape, which is cumbersome to operate and the durability is difficult to guarantee.

[0007] In view of this, it is necessary to improve and develop the headrest structure for assisting cervical spine CT scanning, so as to improve the efficiency of patients' cervical spine CT scanning and adapt to the increasingly busy patients' CT scanning needs. Utility Model Content

[0008] In order to solve the problem that the pillow used in current clinical medicine for cervical spine CT scanning cannot properly fix the subject in a suitable posture, and in order to ensure the success rate of the scan, it is often necessary to use air bags or elastic bands to pull the shoulders of the subject, which is troublesome and easy to cause discomfort to the patient, a lying position correction cervical spine scanning pillow is provided.

[0009] A lying-position correction cervical scanning pillow comprises a pillow base placed on an examination bed, an alignment base is arranged at the bottom of the pillow base, the width of the alignment base is the same as that of the examination bed, the left and right sides of the alignment base are parallel to each other, a cervical groove is arranged at the middle upper end of the pillow base, a cervical elevation slope is also coaxially arranged at the front end of the cervical groove, and the cervical elevation slope is inclined downward toward the front.

[0010] Furthermore, the cervical vertebra elevating slope is in the shape of an inverted triangle from the side close to the cervical vertebra groove to the front end, and the cervical vertebra elevating slope is integrally formed with the pillow base.

[0011] Furthermore, a cervical vertebra positioning portion with a recessed middle portion is provided on the front end of the cervical vertebra groove and the surface of the cervical vertebra lifting slope.

[0012] Furthermore, a concave back-of-the-head positioning portion is coaxially arranged in the middle of the rear side surface of the cervical vertebra groove.

[0013] Furthermore, a chamfered arc surface is provided between the middle portion of the cervical groove and the top of the back head positioning portion.

[0014] Furthermore, vertical planes are symmetrically arranged on the left and right sides of the alignment base, and chamfered arc edges are arranged on the upper and lower ends of the vertical planes.

[0015] Furthermore, positioning clips protruding downwards are symmetrically arranged on left and right sides of the bottom of the alignment base.

[0016] Furthermore, a plurality of anti-slip strips protruding downward are arranged at the bottom of the pillow base, and the anti-slip strips are V-shaped.

[0017] Furthermore, a convex arc surface is provided at the bottom center of the pillow base and the cervical vertebra elevating slope.

[0018] Furthermore, the width of the cervical groove is smaller than that of the pillow base, and the top of the cervical groove is higher than the top of the cervical elevation slope.

[0019] The advantages of the utility model are:

[0020] 1. Use the alignment base to quickly align the examination bed, effectively avoiding the deviation of the subject's lying position. No additional straps or other mechanisms are required to fix the subject, providing a good user experience.

[0035] like Figure 1-4 As shown, this embodiment provides a lying-position correction cervical scanning pillow, including a pillow base 1 placed on an examination bed (not shown in the figure), a positioning base 101 is arranged at the bottom of the pillow base 1, the width of the positioning base 101 is the same as that of the examination bed, the left and right sides of the positioning base 101 are parallel to each other, a cervical groove 2 is arranged at the upper middle end of the pillow base 1, a cervical elevation slope 3 is also coaxially arranged at the front end of the cervical groove 2, and the cervical elevation slope 3 is inclined downward to the front.

[0036] Since the width of the pillow is just in line with the width of the CT scanning examination bed, medical staff can quickly determine that the position of the pillow is parallel to the bed. The cervical groove 2 is set in the middle of the pillow, which fits the cervical spine of most people, avoiding uneven shoulders due to incorrect lying posture, and reducing hardening artifacts that block the observation of the lower cervical spine. In addition, the cervical elevation slope 3 raises the lower cervical spine of the examinee when he lies down, making the examinee's clavicles more flush and the shoulders closer to the bed surface.

[0037] The cervical vertebra elevating slope 3 is inverted triangle from the side close to the cervical vertebra groove 2 to the front end, and the cervical vertebra elevating slope 3 is integrally formed with the pillow base 1. The inverted triangle design is ergonomic, and can lift the cervical vertebra while making the shoulders tilt down close to the bed surface, avoiding the shoulders from blocking the cervical vertebra during CT scanning.

[0038] The front end of the cervical groove 2 and the surface of the cervical elevation slope 3 are provided with a cervical vertebra positioning portion 4 with a concave middle portion. The concave cervical vertebra positioning portion 4 can clamp the subject to be examined and improve the positioning stability.

[0039] The middle part of the rear side of the cervical groove 2 is coaxially provided with a concave back head positioning part 5. The back head positioning part 5 can similarly clamp the position of the head on the cervical spine of the subject to prevent the subject from tilting his head to cause the cervical spine positioning deviation.

[0040] A chamfered arc surface 501 is provided between the middle of the cervical groove 2 and the top of the back head positioning part 5. The chamfered arc surface 501 is ergonomic and can improve the comfort of the pillow. When the subject rests his head in the cervical groove 2, he will not touch any sharp protrusions.

[0041] The alignment base 101 is symmetrically provided with vertical planes 102 on both sides, and the upper and lower ends of the vertical plane 102 are both provided with chamfered arc edges 103. The design of the vertical plane 102 facilitates medical staff to observe the side of the alignment base 101 and the side of the examination bed for alignment; and the chamfered arc edge 103 can eliminate sharp corners to avoid collision damage.

[0042] The bottom of the pillow base 1 is provided with a plurality of anti-skid strips 6 protruding downwards, and the anti-skid strips 6 are V-shaped. The V-shaped anti-skid strips 6 can provide a strong surface friction force to prevent the pillow from being deflected by force.

[0043] The center of the bottom of the pillow base 1 and the cervical vertebra lifting slope 3 is provided with a convex arc surface 7. Since the pillow is generally made of soft material, and the surface of the CT examination bed mostly has a shallow depression, the convex arc surface 7 convex downwardly is provided to ensure that the bottom of the pillow fits the examination bed, and the anti-slip strip 6 is used to ensure the positioning stability of the pillow.

[0044] The width of the cervical groove 2 is smaller than the pillow base 1, and the top of the cervical groove 2 is higher than the top of the cervical elevation slope 3. The width of the cervical groove 2 is close to the width of the human neck, and the neck of the examinee can be clamped in the middle of the examination bed to avoid position deviation. In addition, the top of the cervical groove 2 is the highest point when the examinee lies down, which is ergonomic and can clamp the middle of the cervical spine to improve positioning stability. Example 2

[0045] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the bottom of the alignment base 101 is symmetrically provided with downwardly protruding positioning clips 8 on the left and right sides. The symmetrical positioning clips 8 can clamp the sides of the examination bed, further improving the positioning stability of the pillow and preventing the force deviation from causing the patient's posture to shift.

[0046] It is worth mentioning that during the examination, the subject is asked to lie on his back on the CT examination bed with his head and neck resting on the utility model. The medical staff then teaches the subject to cross his fingers and press back toward the front and lower part of the subject, so that the shoulders of the subject have a pulling force toward the feet of the human body, which replaces the effect of the elastic stretch belt in the past invention. The subject can press down with his own best strength to reduce the pain of using the elastic belt, and the technician can also reduce the operation time of debugging the machine to press down or to tie the belt for the subject, thereby simplifying the examination process.

[0047] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
