Description

Technical Field

[0001] This invention relates to the field of pet medical equipment and provides a body positioning device for animal CT scans. Background Technology

[0002] Pet CT scans use X-rays and computer processing technology to generate cross-sectional images of the animal's internal body, helping veterinarians make accurate diagnoses and develop treatment plans. Through CT scans, veterinarians can observe complex fractures, joint injuries, brain diseases, oral problems, and tumors in animals, thus providing more precise treatment and care for their pets.

[0003] To ensure the accuracy and clarity of CT scan results for animals, they must be restrained in a specific position to prevent movement during the scan. Typically, the animal is placed on a special scanning bed and restrained using straps or other devices. For some small pets, chemical sedatives may be necessary to keep them still during the scan.

[0004] While existing animal CT scan immobilization devices can meet scanning needs to some extent, they still have some shortcomings. Particularly when immobilizing a pet's limbs, head, and tail, existing devices are often cumbersome and inefficient. Because pets often struggle during the scan due to fear or discomfort, the immobilization devices struggle to quickly and accurately secure their limbs, head, and tail. This not only increases the difficulty and time of the scan but may also affect the accuracy and clarity of the scan results. Utility Model Content

[0005] To address the aforementioned deficiencies, the present invention aims to provide a body positioning device for animal CT scans, thereby solving the problems mentioned in the background art. The device includes a support platform mounted on a base, with a movable bed slidably connected to the top of the support platform along its length. The top of the movable bed is provided with several sliding grooves, and several positioning buckles are slidably connected to the sliding grooves. The positioning buckles are engaged within the sliding grooves and can slide along the trajectory of the sliding grooves. The sliding grooves include two head and tail fixing grooves arranged along the length of the movable bed, four limb fixing grooves arranged obliquely, and several arc-shaped grooves arranged on the limb fixing grooves. The positioning buckles are provided with a tightening and loosening mechanism.

[0006] Furthermore, the four limb fixation grooves are centrally symmetrically distributed, and several arc-shaped grooves are evenly arranged along the length of each limb fixation groove, with the curvature of the arc-shaped grooves pointing towards the center of the extension lines of the four limb fixation grooves.

[0007] Furthermore, the positioning buckle includes an insert that is snapped into the inside of the slide groove, and the insert can slide inside the slide groove; a column is installed on the top of the insert, the column is a cylindrical structure, and a locking ring is threadedly connected to the outer side of the column through a threaded part.

[0008] Furthermore, a locking pad is fixedly connected to the bottom of the locking ring, and the locking pad is made of a soft material.

[0009] Furthermore, the elastic buckle mechanism includes a support mounted on the top of the column. The support has through slots on two opposite sides. An elastic Velcro is inserted into the through slot. One end of the elastic Velcro is fixedly connected to a locking post.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0022] See Figure 1-4 The purpose of this utility model is to provide a positioning device for animal CT scans, including a support platform 2 mounted on a base 1. A movable bed 3, which can slide along the length of the support platform 2, is slidably connected to the top of the support platform 2. The base 1 is provided with a drive mechanism that can drive the movable bed 3 to slide on the support platform 2. This positioning device is used in conjunction with a pet CT scanner to perform CT scans on pets. During the X-ray scan, the movable bed 3 moves at a constant speed towards the scanning position of the CT scanner under the drive mechanism, thereby forming a scan model. The scanning imaging principle of the CT scanner and the operating principle of the movable bed 3 driven by the drive mechanism are existing technologies. For details, please refer to Chinese invention patent application number CN201910821286.2, filed on September 2, 2019: "A Multi-segment Pet Diagnostic Bed and Its Positioning Method".

[0023] The top of the mobile bed 3 has several sliding grooves 31, and several positioning buckles 4 are slidably connected to the sliding grooves 31. The positioning buckles 4 are engaged within the sliding grooves 31 and can slide along the trajectory of the sliding grooves 31. This method allows the positioning buckles 4 to be adjusted in position on the mobile bed 3. The positioning buckles 4 can be used to fix the pet's limbs and can also be responsible for positioning the tail and head, preventing the pet's body from swaying or moving on its own during the movement of the mobile bed 3, which could lead to unclear scan images. In actual use, to prevent the pet from moving during the CT scan, a sedative is needed to ensure that the pet remains still during the scan, and the positioning buckles 4 are used to quickly position the pet's posture.

[0024] Specifically, the slide groove 31 on the moving bed 3 includes two head and tail fixing grooves 311 arranged along the length direction of the moving bed (that is, the direction of movement of the moving bed 3), four limb fixing grooves 313 arranged obliquely, and several arc-shaped grooves 312 arranged on the limb fixing grooves 313.

[0025] The four limb fixation grooves 313 are centrally symmetrically distributed. At the same time, each limb fixation groove 313 has several arc-shaped grooves 312 evenly distributed along the length of the limb fixation groove 313. The curvature direction of the arc-shaped grooves 312 is towards the center of the extension line of the four limb fixation grooves 313. Thus, the slide groove 31 can match the limb fixation points of various pets of different sizes, and fix the pets more scientifically at the fixation points.

[0026] The positioning buckle 4 includes an insert 41 that snaps into the inside of the slide groove 31 and can slide inside the slide groove 31. A post 42 is mounted on the top of the insert 41. The post 42 has a cylindrical structure. A locking ring 420 is threaded to the outer side of the post 42 through a threaded part 421. A tensioning buckle mechanism for securing the pet's limbs is fixedly connected to the top of the post 42.

[0027] Therefore, when using this fixation device, the pet is first sedated to ensure it remains still. Then, the pet is placed on the mobile bed 3. Based on the pet's size and scanning requirements, the position of the positioning buckle 4 is adjusted within the sliding groove 31 on the mobile bed 3 using the sliding positioning buckle 4. The head and tail fixing groove 311 is used to fix the pet's head and tail, while the limb fixing groove 313 and its arc-shaped groove 312 are used to match and fix the pet's limbs. The positioning buckle 4 slides within the sliding groove 31 via the insert 41. When it reaches the appropriate position, the locking ring 420 on the rotating column 42 moves downwards, and correspondingly, the insert 41 moves upwards, thereby reducing the distance between the insert 41 and the locking ring 420. Friction locks the position of the positioning buckle 4, completing its positioning and fixation. Subsequently, the drive mechanism is activated, causing the mobile bed 3 to move at a constant speed within the CT scanner's scanning position, thus completing the scanning imaging.

[0028] Preferably, a locking pad 422 is fixedly connected to the bottom of the locking ring 420. The locking pad 422 is made of a soft material, preferably rubber. The rubber locking pad 422 can provide a certain elastic deformation when the locking ring 420 is tightened, while increasing the friction and achieving better tightening and fixing.

[0029] Preferably, the fastening mechanism includes a support 43 fixedly connected to the top of the column 42. The support 43 has slots 432 on two opposite sides, and a Velcro fastener 44 is inserted into each slot. One end of the Velcro fastener 44 is fixedly connected to the locking post 441, and the other end passes through both slots 432 and folds back to fit against the top surface of the Velcro fastener 44. The Velcro fastener 44 uses a common double-sided Velcro fastener, allowing for easy tightening and loosening.

[0030] Preferably, the top of the support 43 is provided with a recess 431, and the top of the recess 431 is provided with an anti-slip layer. The anti-slip layer is an adhesive part of soft rubber, which can increase the friction between the pet's limbs and prevent the pet's limbs from coming out of the fastening mechanism.

[0031] Preferably, a limiting block 411 is fixedly connected to the top of the insert 41. The limiting block 411 has a cylindrical structure, and the column 42 has a slot that matches the limiting block 411. The limiting block 411 can rotate inside the slot. Thus, during the adjustment of the fastening mechanism, the support 43 can freely rotate on the top of the moving bed 3 to adjust the fixed direction.

[0032] In summary, in actual use, the pet is first sedated to ensure it remains still. The pet is then placed on the mobile bed 3. Depending on the pet's size and scanning requirements, the sliding positioning buckle 4 adjusts its position within different types of grooves 31. The head and tail fixing groove 311 secures the pet's head and tail, while the limb fixing grooves 313 and arc-shaped grooves 312 match and secure the pet's limbs. After the positioning buckle 4 slides into position within the groove 31 via the insert 41, the locking ring 420 is rotated to reduce the distance between the insert 41 and the locking ring 420, locking the position through friction. The elastic buckle 44 of the elastic buckle mechanism passes through the through-groove 432 on the support 43 to secure the pet's limbs. The anti-slip layer on the recess 431 at the top of the support 43 prevents the pet's limbs from slipping out. Furthermore, the limiting block 411 at the top of the insert 41 allows the support 43 to rotate freely to adjust the fixing direction. Then, the drive mechanism is activated, moving the mobile bed 3 at a constant speed towards the CT scanner scanning position to complete the scanning and imaging.

[0033] Therefore, this device, through its unique groove layout 31, including centrally symmetrically distributed limb fixation grooves 313 and curved grooves 312, can match the limb fixation points of various pets of different sizes, scientifically and effectively securing the pet. The sliding and locking design of the positioning buckle 4 facilitates adjustment of the fixation position. The use of the elastic magic buckle 44 in the elastic buckle mechanism makes pet limb fixation easy and convenient. When used with a pet CT scanner, this device can quickly and accurately fix the pet's position, preventing the pet's body from swaying or moving voluntarily during scanning, effectively improving the clarity of the scan image, providing a more reliable basis for the diagnosis of pet diseases, and also improving the efficiency and quality of the overall scanning work.

[0034] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
