Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fixation strap for PET / CT brain examination. Background Technology

[0002] PET / CT stands for Positron Emission Tomography-Computed Tomography. It is an imaging examination device that organically combines two advanced imaging technologies: PET (Positron Emission Tomography) and CT (Computed Tomography). During a PET / CT examination, to ensure image quality and provide reliable diagnostic information, the patient lying on the examination table is usually required not to move their head during the procedure.

[0003] During examinations, comatose or agitated patients require head PET / CT scans to identify intracranial hemorrhage or hematoma, tumor compression, and other diseases such as lesion location, in order to promptly initiate targeted treatment, save the patient's life, and reduce disability rates. However, these patients are already in a coma during PET / CT scans, generally exhibiting symptoms such as delirium and agitation, with involuntary head movements, making it difficult to complete the head PET / CT scan or resulting in poor image quality. To help examiners complete the examination quickly and with high quality, a head immobilization device is needed to fix the patient's head to the examination table without damaging the patient or affecting the PET / CT image quality.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, this utility model provides a fixing strap for PET / CT brain examination, including a strap 4 fixed to a pillow body 11 of an examination bed 1. The strap 4 includes a fixed end and a movable adjustment end. Fixed connectors and adjustment openings 12 are respectively provided on opposite sides of the pillow body 11. The fixed end is fixedly installed on the fixed connectors. An installation cavity 13 is provided inside the pillow body 11. A rotating adjustment member 2 is rotatably provided in the installation cavity 13. The movable adjustment end of the strap 4 extends from the adjustment opening 12 into the installation cavity 13 and is wrapped around the rotating adjustment member 2. The driving end of the rotating adjustment member 2 extends from the end of the pillow body 11 and is connected to a rotating operating member 21. The rotating adjustment member 2 is driven by the rotating operating member 21 and can rotate in different directions to tighten or loosen the strap 4. A locking component 3 is provided on the pillow body 11, and a locking structure 24 is provided on the rotating adjustment member 2. The locking component 3 and the locking structure 24 have a locked state and an unlocked state.

[0023] Specifically, the examination bed 1 includes a bed frame and a pillow 11 set on the bed frame. The examination bed 1 is set in correspondence with the PET / CT examination equipment 16. The pillow 11 is for placing the patient's head during the examination. The pillow 11 may also be provided with a groove for placing the head. The belt 4 is installed on the pillow 11. The two ends of the belt 4 are a fixed end and an adjustable end, respectively. Fixed connectors and adjustment openings 12 are respectively provided on opposite sides of the pillow 11. The fixed end of the belt 4 is fixedly installed on the fixed connector. The other end of the belt 4 passes through the adjustment opening 12 into the mounting cavity 13. The section of the belt 4 between the fixed connector and the adjustment opening 12 is the fixed section, which can fix the patient's head on the pillow 11.

[0024] In this embodiment, a mounting cavity 13 is provided inside the pillow body 11, and the mounting cavity 13 is connected to the adjustment opening 12. The rotating adjustment member 2 is rotatably mounted in the mounting cavity 13, with one end of the rotating adjustment member 2 rotatably mounted inside the mounting cavity 13. A rotating channel 14 is provided on the pillow body 11. The driving end of the rotating adjustment member 2 extends from the end of the pillow body 11 and is connected to a rotating operating member 21. The movable adjustment end of the belt body 4 extends from the adjustment opening 12 into the mounting cavity 13 and is wound around the rotating adjustment member 2, thereby adjusting the rotating operating member 21. The rotation operation allows the rotating adjustment component 2 to rotate in the desired direction. For example, when the rotating operation component 21 and the rotating adjustment component 2 rotate in the first direction, the belt 4 gradually wraps around and tightens on the rotating adjustment component 2. This reduces the length of the fixed section on the belt 4 until the fixed section can fix the patient's head. Conversely, when the rotating operation component 21 and the rotating adjustment component 2 rotate in the second direction (opposite to the first direction), the belt 4 on the rotating adjustment component 2 gradually loosens. At this time, pulling the belt 4 can increase the length of the fixed section.

[0025] In this embodiment, a locking component 3 is provided on the pillow body 11, and a corresponding locking structure 24 is provided on the rotating adjustment component 2. The locking component 3 and the locking structure 24 cooperate with each other to have a locked state and an unlocked state. When the locking component 3 and the locking structure 24 are in the unlocked state, the rotating operation component 21 and the rotating adjustment component 2 can be driven to rotate. When the locking component 3 and the locking structure 24 are in the locked state, the rotating operation component 21 and the rotating adjustment component 2 are locked and cannot rotate.

[0026] The present invention provides a PET / CT brain examination fixation strap, comprising a strap 4 fixed to a pillow body 11 of an examination bed 1. The fixed end of the strap 4 is fixedly installed on a fixing connector of the pillow body 11. The pillow body 11 has an installation cavity 13 inside, and a rotating adjustment component 2 is rotatably installed in the installation cavity 13. The movable adjustment end of the strap 4 extends from the adjustment opening 12 of the pillow body 11 into the installation cavity 13 and is wrapped around the rotating adjustment component 2. The rotating adjustment component 2 can be driven to rotate by a rotating operating component 21, thereby realizing the winding or unwinding of the strap 4, thus fixing the examinee's head on the pillow body 11. At the same time, a locking component 3 is provided on the pillow body 11, and a locking structure 24 corresponding to the locking component 3 is provided on the rotating adjustment component 2. The rotating adjustment component 2 can be locked by the locking structure 24 and the locking component 3, thereby enabling the strap 4 to maintain fixation on the patient's head.

[0027] In this embodiment, preferably, the rotating adjustment member 2 includes a rotating body 22 and a rotating drive rod 23 disposed at the end of the rotating body 22. The pillow body 11 is provided with a rotating channel 14 communicating with the mounting cavity 13. The rotating channel 14 is coaxially disposed with the mounting cavity 13. The end of the rotating drive rod 23 extends out from the rotating channel 14 and is connected to the rotating operating member 21. The rotating body 22 is rotatably installed in the mounting cavity 13, and the rotating drive rod 23 is rotatably connected inside the rotating channel 14. The radial dimension of the rotating operating member 21 is larger than the radial dimension of the rotating drive rod 23. The rotating operating member 21 can drive the rotating drive rod 23 and the rotating body 22 to rotate.

[0028] In this embodiment, preferably, the pillow body 11 is provided with an opening 15, which is a cylindrical cavity. The opening 15 is coaxially arranged with the rotating channel 14, and the radial dimension of the opening 15 is larger than the radial dimension of the rotating channel 14. The locking structure 24 and the locking component 3 are both arranged inside the opening 15.

[0029] In this embodiment, preferably, the locking structure 24 includes an annular mounting member 25, which is fixedly mounted on the rotating drive rod 23. The annular mounting member 25 is rotatably disposed within the opening 15, and the annular mounting member 25 is provided with a plurality of locking grooves 251 along the circumferential direction.

[0030] In this embodiment, preferably, the locking component 3 includes an annular locking member 31, on which an annular moving plate 32 is provided. The annular locking member 31 and the annular moving plate 32 are an integral structure. The radial dimension of the annular moving plate 32 is larger than that of the annular locking member 31. The annular moving plate 32 is slidably connected within the opening 15. On the side of the annular locking member 31 away from the annular moving plate 32, there is a locking tooth 311 corresponding to the locking groove 251. The annular moving plate 32 and the opening 15 can be slidably connected through different structures. For example, an axial groove is provided on the side wall of the opening 15. There are at least two axial grooves. The axial grooves are arranged in a direction parallel to the axis of the opening 15. A sliding block is provided on the annular moving plate 32. The sliding block is slidably connected within the axial groove, so that the annular moving plate 32 can move along the axis of the opening 15.

[0031] In this embodiment, preferably, a connecting cylinder 33 is provided on the annular motion plate 32, and the connecting cylinder 33 is arranged around the rotating drive rod 23. An annular pull member 34 is provided at the end of the connecting cylinder 33. The locking assembly 3 also includes a spring member 35, one end of which is fixed to the bottom of the opening 15, and the annular motion plate 32 is fixedly connected to the other end of the spring member 35. When the spring member 35 is in the initial state, under the action of the spring member 35, the locking teeth 311 on the annular locking member 31 lock with the locking grooves 251 on the annular mounting member 25. In this way, the annular locking member 31 and the annular mounting member 25 are locked, and the rotating drive rod 23 is locked and cannot rotate. If it is necessary to adjust the locking mechanism, the locking mechanism can be adjusted accordingly. When the rotary drive rod 23 rotates, it pulls the annular pull member 34, causing the annular pull member 34 to move away from the annular mounting member 25 until the locking serration 311 separates from the locking groove 251. At this time, the spring member 35 is stretched and becomes elastic. Thus, the rotary drive rod 23 and the rotating body 22 can be driven to rotate by rotating the operating head. When the rotary drive rod 23 and the rotating body 22 rotate to the appropriate position, the pull on the annular pull member 34 is released. Under the action of the spring member 35, the annular locking member 31 moves to the initial position, and the locking serration 311 on the annular locking member 31 locks with the locking groove 251 on the annular mounting member 25.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
