Description

Technical Field

[0001] The present invention relates to the technical field of medical device equipment, and particularly relates to a headrest for a CT scanning device. Background Art

[0002] In the field of medical diagnosis, CT scanning is a key technical means for disease detection. Especially for patients without autonomous consciousness such as those in a coma, ensuring the stable fixation of their body posture is not only a prerequisite for obtaining clear images but also a core requirement for ensuring patient safety. Currently, the traditional CT scanning auxiliary device has long focused its design on the positioning of the patient's head, and restricts the patient's head through a headrest to reduce image artifacts caused by head shaking during scanning.

[0003] However, this design pattern exposes an obvious functional neglect: there is a serious lack of technology in the management of the patient's arms. The arms of patients without autonomous consciousness are prone to naturally drooping under the action of gravity due to the loss of nerve control. The scanning components of the CT device need to operate dynamically along a preset trajectory, and the risk of collision between the drooping arms and the scanning components increases significantly. Such a collision will not only directly cause physical injuries such as abrasions and contusions to the patient's limbs, but also lead to abnormal operation of the device, resulting in the interruption of the scanning process and distortion of the image data, ultimately affecting the doctor's accurate judgment of the condition and delaying the diagnosis and treatment opportunity. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a headrest for a CT scanning device, which can effectively fix the patient's arms, prevent the arms from colliding with the components of the CT scanning device due to gravity drooping during scanning, and can also flexibly adjust the position of the handrest according to the differences in the arm lengths of different patients, avoiding excessive outward orientation of the two elbows, and improving the comfort of the patient and the accuracy of scanning.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A headrest for a CT scanning device, including a headrest body installed on a CT scanning bed body. The headrest body is provided with an adjustable handrest. The handrest includes a wrapping member for fixing the arm and a moving member for driving the movement of the wrapping member. The moving member is slidably connected to the handrest. The handrest is provided with a control member connected to the moving member. By driving the moving adjustment mechanism to move along a preset direction through the control member, the position adjustment of the wrapping member is realized. Both the headrest body and the handrest are made of medical-grade materials that do not interfere with X-rays.

[0006] Preferably, the hand support member further includes a hand support plate, and the wrapping member is disposed on the hand support plate. The wrapping member includes a supporting airbag and a wrapping airbag, and the supporting airbag and the wrapping airbag are communicated through an air passage. The supporting airbag is triggered by the gravity of the arm to inflate the wrapping airbag, forming a self-wrapping state. This design does not require additional operations and automatically responds to the placement action of the patient's arm, and can quickly and efficiently fix the arm. Compared with the manual fixing method, it not only saves the operation time of medical staff, but also ensures the consistency and stability of fixation.

[0007] Preferably, the hand support member further includes a fixing plate and a support platform. The fixing plate is connected to the head support body, the hand support plate is connected to the support platform, the support platform is connected to the moving member, and there are two hand support members. The two hand support members are symmetrically disposed on both sides of the head support body, and the two hand support members are connected by a connecting plate. The two symmetrically designed hand support members can stably support the patient's arms at the same time, and the structural design of the fixing plate and the support platform enhances the overall stability of the hand support member.

[0008] Preferably, two one-way valves for communication are provided between the supporting airbag and the wrapping airbag. One of the one-way valves controls the flow of gas in the supporting airbag towards the wrapping airbag, and the other one-way valve controls the flow of gas in the wrapping airbag towards the supporting airbag. The two one-way valves respectively control the bidirectional flow of gas. One one-way valve realizes the inflation of the supporting airbag to the wrapping airbag, and the other controls the backflow of the wrapping airbag to the supporting airbag. This bidirectional air passage control design works in cooperation with the elastic reset member to ensure that the wrapping airbag inflates and wraps when the arm is placed, and deflates and resets after the arm is lifted, forming a complete and automatic working cycle.

[0009] Preferably, the wrapping airbag is an airbag with wrinkles on the side during use. The wrapping member further includes a reset member, and reset members made of elastic materials are provided in both the wrapping airbag and the supporting airbag. The wrinkled design of the wrapping airbag enables the wrapping airbag to expand laterally and closely fit the arm when inflated, improving the fixing effect. The reset member uses its own elasticity to quickly restore the wrapping airbag to its original state after the arm is lifted, and the wrinkles contract. The reset member in the wrapping airbag can be selected as an elastic rubber strip during use, and the reset member in the supporting airbag can be selected as a highly elastic sponge or a spring during use, which can reset the supporting airbag after the patient's arm is lifted.

[0010] Preferably, the moving member includes a moving plate and a clamping plate. A moving groove is provided on the fixed plate, and a plurality of clamping teeth are equidistantly arranged in the moving groove. The moving plate is movably arranged in the moving groove.

The clamping plate is elastically connected to the fixed block through the first spring and is in clamping cooperation with the clamping teeth on the fixed plate. The clamping plate is connected to the control member. The moving plate can achieve multi-level positioning in the moving groove. By controlling the engagement and disengagement of the clamping plate and the clamping teeth through the control member, the position of the wrapping member can be accurately adjusted. Medical staff can quickly and accurately adjust the position of the hand support according to the actual situation of the patient's arm, meeting the needs of different patients and improving the versatility and applicability of the head support.

[0011] Preferably, the control member includes a control grip and a cable assembly. A guide rod is provided on the control grip. The guide rod is movably arranged on the connecting plate. A second spring is sleeved on the guide rod. The second spring is located between the control grip and the connecting plate. One end of the control grip is connected to the cable assembly, and the other end of the cable assembly is connected to the clamping plate. The control grip drives the clamping plate to disengage from the clamping teeth through the cable assembly. There are two cable assemblies. The control grip is connected to the clamping plates on two moving members respectively through the two cable assemblies. When pulling the control grip, the guide rod moves to compress the second spring, and the clamping plate is driven to disengage from the clamping teeth through the cable assembly. The operation is simple and direct. Medical staff only need to simply pull the grip to complete the unlocking and adjustment of the moving member, reducing the operation difficulty and improving the work efficiency.

[0012] Preferably, the cable assembly includes a first cable, a pull rod, and a rotating rod. One end of the first cable is connected to the control grip, and the other end of the first cable is connected to the pull rod. The pull rod is movably arranged in the moving plate.

The two ends of the rotating rod are respectively connected to the second cable and the third cable through the connection ends three. When the first cable, the second cable, and the third cable are respectively connected to the control grip, the pull rod, the rotating rod, and the clamping plate, various connection methods can be used for connection. They can be bound and connected with metal ring buckles, or connection holes for the rope body to penetrate can be opened at the ends, and the rope heads in the connection holes can be squeezed and fixed by screwing bolts. When pulling the control grip, the force is accurately transmitted to the clamping plate through the first cable, the pull rod, the second cable, the rotating rod, and the third cable, driving its movement.

[0013] Preferably, a groove communicating with the movable groove is provided in the movable plate. A supporting block and a plurality of stabilizing blocks are provided in the groove. The supporting block is located below the pull rod. A supporting groove adapted to the pull rod is provided on the supporting block. The pull rod is located in the supporting groove. A hole for the first pulling rope to pass through is provided on the stabilizing block. The supporting block provides stable support for the pull rod, preventing it from shaking or shifting during movement and ensuring the accuracy of force transmission. The stabilizing blocks limit and guide the first pulling rope, reducing the friction and displacement of the first pulling rope during movement, further enhancing the stability and reliability of the operation of the control member, and improving the accuracy and smoothness of the adjustment of the entire movable member.

[0014] Preferably, a first guiding plate is provided on the movable plate, and a second guiding plate is provided on the connecting plate. Second guiding grooves are provided on both the first guiding plate and the second guiding plate. The first pulling rope is located in the second guiding grooves on the first guiding plate and the second guiding plate.

[0033] In the present application, each part is made of materials that have no impact on CT imaging during production and processing, such as carbon fiber composite materials, medical-grade polyetheretherketone, etc. When a patient needs to undergo a CT scan, medical staff assist the patient to lie on the bed, place the patient's head in a suitable position on the headrest body 1 to ensure that the head is comfortable and stable. Then, place the patient's arms on the armrest plates 23 of the two side armrest members 2 respectively, and the arms naturally rest on the supporting airbags 241. At this time, the gravity of the arms will compress the supporting airbags 241, causing the gas in the supporting airbags 241 to flow into the wrapping airbags 242 through the one-way valve. After the wrapping airbags 242 are inflated, the folds on the side will unfold horizontally and gradually fit the sides of the arms, forming a wrapping and fixation of the patient's arms. Medical staff can appropriately adjust the position of the arms according to the actual situation of the patient's arms to ensure the best wrapping effect; Since there are differences in the arm lengths of different patients, when placing the arms, it may occur that the two elbows are overly outward. At this time, medical staff can pull the control grip 51. When pulling the control grip 51, the guide rod 52 will move on the connecting plate 4, compressing the second spring 53. At the same time, the first pull rope 54 drives the pull rod 55 to move. The movement of the pull rod 55 will pull the rotating rod 56 to rotate through the second pull rope 57. The rotating rotating rod 56 will then pull the clamping plate 33 to move through the third pull rope 58, causing the clamping plate 33 to disengage from the clamping teeth 212 on the fixed plate 21. At this time, the moving member 3 is unlocked. Medical staff can push or pull the connecting plate 4, and the connecting plate 4 drives the moving plate 31 to move through the support platform 22, so that the moving plate 31 slides in the moving groove 211 of the fixed plate 21 along a preset direction, thereby driving the wrapping member 24 to move to a suitable position, making the patient's arms in a more natural and comfortable state, avoiding the elbows being overly outward. After the adjustment is completed, release the control grip 51, and the second spring 53 will return to its original state, pushing the control grip 51 back to its original position. The clamping plate 33 will re-engage with the clamping teeth 212 under the action of the first spring 3126 to fix the position of the moving member 3, completing the position adjustment of the wrapping member 24. After completing the fixation and position adjustment of the patient's head and arms, the CT scanning device can start the scanning work. During the scanning process, the wrapping member 24 will continuously fix the patient's arms to prevent the arms from drooping and colliding with the scanning device, ensuring the smooth progress of the scanning work; When the CT scan is over, medical staff assist the patient to lift the arms from the armrest member 2. At this time, the elastic reset members in the wrapping airbags 242 and the supporting airbags 241 use their own elastic restoring forces to cause the wrapping airbags 242 to return to the initial state. At the same time, the gas in the wrapping airbags 242 flows back to the supporting airbags 241 under the action of another one-way valve, and the folds on the wrapping airbags 242 contract, preparing for the next use.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may have any variations or modifications without departing from the said principles.
