Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a head CT adjustment device for the imaging department. Background Art

[0002] The imaging department is one of the important auxiliary examination departments in the hospital. Many diseases in various clinical departments need to be examined through the imaging department equipment to make a clear diagnosis or auxiliary diagnosis. CT is an important device in the imaging department. During the CT scan, if the patient's head shakes, the imaging quality of the CT machine will be reduced, and only blurred images can be obtained, which will bring difficulties to the diagnosis of medical staff. Therefore, when performing a CT examination in the imaging department, a head fixation component is generally used to fix the patient's head, so as to avoid the head movement of the patient during CT irradiation and generate artifacts that affect the doctor's diagnosis.

[0003] In the prior art, a Chinese patent with the patent number CN110123359A discloses a CT examination adjustable headrest for the imaging department, which relates to the technical field of medical devices. It includes a base, and a groove is opened on the upper surface of the base. A fixing ring is fixedly connected to the upper surface of the base, and sliding sleeves are clamped on the left and right sides of the surface of the fixing ring, and sliding rods are sleeved in the sliding sleeves. For this CT examination adjustable headrest for the imaging department, through the mutual cooperation of the clamping device, the rotating block, the threaded rod and the support plate, when the patient's head is placed on the support plate, people rotate the rotating block, and the rotation of the rotating block drives the threaded rod to rotate. The rotation of the threaded rod under the action of the threaded hole will move upward, so as to adjust the angle of the patient's head to tilt up. At the same time, the valve is opened, and the negative pressure ball is pressed. The negative pressure ball inflates the airbag through the connecting pipe and the air inlet pipe, so that the clamping plate clamps the patient's head.

[0004] Therefore, the prior art clamps the patient's head by rotating the rotating block and opening the valve after the patient lies flat, which makes the device very inconvenient to use. At the same time, the device has a complex structure. For this reason, we propose a head CT adjustment device for the imaging department. Summary of the Invention

[0005] The purpose of the present invention is to provide a head CT adjustment device for the imaging department. The patient can lie flat on the CT scanning bed board, and the patient's head is horizontally placed inside the T-shaped frame. With the cooperation of the fitting component and the clamping component, the patient's head can be stably limited while ensuring comfort. It can also ensure that when the patient lies on the side, the patient's head can still be placed inside the T-shaped frame. Similarly, with the cooperation of the fitting component and the clamping component, the patient's head can be stably limited while ensuring comfort. It has the advantages of simple structure and convenient operation.

A rotating shaft is movably arranged at the upper end of the connecting frame. The middle side wall of the upper end of the T-shaped frame is connected to one end of the rotating shaft. An inclined reinforcing rod is arranged on the connecting frame.

[0009] Preferably, a circular through hole is opened at the end of the T-shaped frame. The fitting component includes a first telescopic column movably arranged inside the circular through hole at the lower end of the T-shaped frame. A first arc-shaped block is arranged at the upper end of the first telescopic column. A first arc-shaped airbag is arranged on the first arc-shaped block. A first cross plate is arranged at the lower end of the first telescopic column. A first spring is arranged between the first cross plate and the lower surface of the lower end of the T-shaped frame.

[0010] Preferably, the fitting component further includes second telescopic columns symmetrically and movably arranged inside the circular through hole at the upper end of the T-shaped frame. A second arc-shaped block is arranged at the upper end of the second telescopic column. A second arc-shaped airbag is arranged on the second arc-shaped block. A second cross plate is arranged at the lower end of the second telescopic column. A second spring is arranged between the second cross plate and the side surface of the side end of the T-shaped frame.

[0011] Preferably, an air pipe is connected through between the two second arc-shaped airbags and the first arc-shaped airbag. The two second arc-shaped airbags and the first arc-shaped airbag are made of a closed leather material. A detachable cotton cloth material cover is sleeved outside the two second arc-shaped airbags and the first arc-shaped airbag.

[0012] Preferably, the clamping component includes a C-shaped block arranged at the upper end of the connecting frame. An auxiliary shaft is movably arranged in the middle of the C-shaped block. A pull rod is arranged at the end of the auxiliary shaft. Pulling columns are symmetrically arranged at both ends of the pull rod. Second driving rods are arranged on the side walls of the two second arc-shaped blocks. Slide rails are respectively arranged at the ends of the second driving rods. The two slide rails are symmetrically distributed about the central axis of the auxiliary shaft, and the two pulling columns are respectively located inside the two slide rails.

[0013] Preferably, a first gear is arranged on the side wall of the pull rod. A second gear is arranged on the side wall of the T-shaped frame. The second gear meshes with the first gear. The thickness of the second gear is greater than the thickness of the first gear.

[0014] Preferably, a sliding through hole is formed in the lower end of the connecting frame. A first driving rod is movably arranged in the sliding through hole. One end of the first driving rod is connected to the side wall of the first arc-shaped block. A gear bar is arranged at the other end of the first driving rod. The gear bar meshes with the second gear. A third spring is movably arranged at the end of the first driving rod. The lower end of the third spring is connected to the connecting frame.

[0015] The technical effects achieved by the present invention are as follows:

[0016] For a head CT adjustment device for the imaging department of the present invention, a patient can lie flat on the CT scanning bed board. The patient's head is horizontally placed inside the T-shaped frame. The fitting component and the clamping component are coordinated to stably limit the patient's head on the premise of ensuring comfort. It can also ensure that when the patient lies on the side, the patient's head can still be placed inside the T-shaped frame. Similarly, the fitting component and the clamping component are coordinated to stably limit the patient's head on the premise of ensuring comfort. When the patient lies down and places the head inside the T-shaped frame, the present invention can automatically fit the patient's head and stably limit the patient's head without manual operation, making the device structure simple and the operation more convenient. When the patient changes from the supine position to the lateral position, the upper end of the T-shaped frame can rotate around the rotating shaft, so as to ensure that when the patient lies on the side, the patient's head can still be placed inside the T-shaped frame. Similarly, the fitting component and the clamping component are coordinated to stably limit the patient's head on the premise of ensuring comfort. Compared with the prior art, the use scenarios and the scope of use are wider.

[0017] For a head CT adjustment device for the imaging department of the present invention, when performing a brain CT on each patient, a set of cotton cloth material covers after disinfection is replaced, and then the replaced cotton cloth material covers are uniformly cleaned and disinfected. By replacing the cotton cloth material covers, the comfort of the second arc-shaped airbag and the first arc-shaped airbag fitting the patient's head is further enhanced, and at the same time, it is cleaner and more hygienic, making the device healthier and more hygienic and avoiding cross-infection of bacteria.

[0018] For a head CT adjustment device for the imaging department of the present invention, when the patient's head presses the first arc-shaped airbag, the first driving rod is synchronously pressed. The first driving rod drives the gear bar to slide downward. Since the gear bar meshes with the second gear, the second gear rotates. The second gear drives the first gear to rotate. The first gear drives the pull rod to rotate. During the rotation of the pull rod, the pull column is driven to rotate. When the pull column rotates around the auxiliary shaft and cooperates with the slide rail, the two slide rails move closer to the middle. The slide rails pull the two second driving rods to contract towards the middle, thereby driving the two second arc-shaped blocks to move closer to the middle synchronously, so as to clamp and limit the patient's head, and finally avoid the generation of artifacts in the results due to the shaking of the patient's head during the brain CT, making the shooting result more accurate.

It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the scope of protection specifically claimed by the present invention.

[0028] As Figure 1 shown, a head CT adjustment device for the imaging department includes a head adjustment device arranged at the end of the CT scanning bed board 1. The head adjustment device includes a connecting frame 2 arranged on the side wall of the end of the CT scanning bed board 1. A T-shaped frame 3 is movably arranged on the connecting frame 2. The end of the T-shaped frame 3 is bent. A fitting assembly 4 is movably arranged at the end of the T-shaped frame 3. A clamping assembly 5 is arranged on the side of the T-shaped frame 3. The clamping assembly 5 cooperates with the fitting assembly 4 to fix the patient's head.

[0029] As Figure 2 shown, in actual use of the present invention, the patient can lie flat on the CT scanning bed board 1, with the patient's head horizontally placed inside the T-shaped frame 3, and in cooperation with the fitting component 4 and the clamping component 5, the patient's head can be stably limited while ensuring comfort. It can also ensure that when the patient lies on their side, the patient's head can still be placed inside the T-shaped frame 3. Similarly, in cooperation with the fitting component 4 and the clamping component 5, the patient's head can be stably limited while ensuring comfort. When the patient lies down and the patient's head is placed inside the T-shaped frame 3, the present invention automatically fits the patient's head and stably limits the patient's head, eliminating the need for manual operation, making the device structure simple and the operation more convenient.

[0030] As Figure 1 shown, the connecting frame 2 is integrally L-shaped. The lower end of the connecting frame 2 is fixedly connected to the side wall of the end of the CT scanning bed board 1. The upper end of the connecting frame 2 is movably provided with a rotating shaft 6. The middle side wall of the upper end of the T-shaped frame 3 is connected to one end of the rotating shaft 6. The connecting frame 2 is provided with an inclined reinforcing rod 7.

[0031] It should be noted that when the patient changes from the supine position to the lateral position, the upper end of the T-shaped frame 3 can rotate 90 degrees around the rotating shaft 6, so that it can still ensure that when the patient lies on their side, the patient's head can still be placed inside the T-shaped frame 3. Similarly, in cooperation with the fitting component 4 and the clamping component 5, the patient's head can be stably limited while ensuring comfort. Compared with the prior art, the use scenario and the scope of use are more extensive.

[0032] As Figure 3 and Figure 4 shown, a circular through hole is provided at the end of the T-shaped frame 3. The fitting component 4 includes a first telescopic column 401 movably arranged inside the circular through hole at the lower end of the T-shaped frame 3. A first arc-shaped block 402 is provided at the upper end of the first telescopic column 401. A first arc-shaped airbag 403 is provided on the first arc-shaped block 402. A first cross plate 404 is provided at the lower end of the first telescopic column 401. A first spring 405 is provided between the first cross plate 404 and the lower surface of the lower end of the T-shaped frame 3. The fitting component 4 further includes second telescopic columns 406 symmetrically and movably arranged inside the circular through hole at the upper end of the T-shaped frame 3. A second arc-shaped block 407 is provided at the upper end of the second telescopic column 406. A second arc-shaped airbag 408 is provided on the second arc-shaped block 407. A second cross plate 409 is provided at the lower end of the second telescopic column 406. A second spring 410 is provided between the second cross plate 409 and the side surface of the side end of the T-shaped frame 3.

[0033] As Figure 3 and Figure 4As shown, in actual use, when the patient's head is placed on the first arc-shaped airbag 403, the first arc-shaped airbag 403 is squeezed, and the gas inside the first arc-shaped airbag 403 is squeezed and enters into the two second arc-shaped airbags 408 through the trachea 411. Finally, the two second arc-shaped airbags 408 and the first arc-shaped airbag 403 fully fit the patient's head, ensuring comfort.

[0034] As Figure 3 and Figure 4 shown, a trachea 411 is connected in a through manner between the two second arc-shaped airbags 408 and the first arc-shaped airbag 403. The two second arc-shaped airbags 408 and the first arc-shaped airbag 403 are made of a closed leather material, and a detachable cotton cloth material cover 412 is sleeved outside the two second arc-shaped airbags 408 and the first arc-shaped airbag 403.

[0035] As Figure 5 shown, in actual use, when performing a brain CT scan for each patient, a set of sterilized cotton cloth material covers 412 is replaced, and then the replaced cotton cloth material covers 412 are uniformly cleaned and sterilized. By replacing the cotton cloth material covers 412, the present invention further enhances the comfort of the second arc-shaped airbag 408 and the first arc-shaped airbag 403 fitting the patient's head, and at the same time is cleaner and more hygienic, making the device healthier and more hygienic and avoiding cross-infection of bacteria.

[0036] As Figure 5 shown, the clamping assembly 5 includes a C-shaped block 501 provided at the upper end of the connecting frame 2. An auxiliary shaft 502 is movably provided in the middle of the C-shaped block 501. A pull rod 503 is provided at the end of the auxiliary shaft 502. Pulling columns 504 are symmetrically provided at both ends of the pull rod 503. Second driving rods 505 are provided on the side walls of the two second arc-shaped blocks 407. Slide rails 506 are respectively provided at the ends of the second driving rods 505. The two slide rails 506 are symmetrically distributed about the central axis of the auxiliary shaft 502, and the two pulling columns 504 are respectively located inside the two slide rails 506. A first gear 507 is provided on the side wall of the pull rod 503. A second gear 508 is provided on the side wall of the T-shaped frame 3. The second gear 508 meshes with the first gear 507. The thickness of the second gear 508 is greater than the thickness of the first gear 507. A sliding through hole is opened at the lower end of the connecting frame 2. A first driving rod 511 is movably provided in the sliding through hole. One end of the first driving rod 511 is connected to the side wall of the first arc-shaped block 402. A gear rack 509 is provided at the other end of the first driving rod 511. The gear rack 509 meshes with the second gear 508. A third spring 510 is movably provided at the end of the first driving rod 511. The lower end of the third spring 510 is connected to the connecting frame 2.

[0037] As Figure 6As shown, it is worth mentioning that when the first arc-shaped airbag 403 is squeezed by the patient's head, the first driving rod 511 is synchronously squeezed. The first driving rod 511 drives the gear bar 509 to slide downward. Since the gear bar 509 meshes with the second gear 508, the second gear 508 rotates. The second gear 508 drives the first gear 507 to rotate. The first gear 507 drives the pull rod 503 to rotate. During the rotation of the pull rod 503, the pull column 504 is driven to rotate. When the pull column 504 rotates around the auxiliary shaft 502, in cooperation with the slide rail 506, the two slide rails 506 move closer to the middle. The slide rails 506 pull the two second driving rods 505 to contract towards the middle, thereby driving the two second arc-shaped blocks 407 to move closer to the middle synchronously, thereby realizing clamping and limiting of the patient's head. Finally, when taking a brain CT, the shaking of the patient's head is avoided from generating artifacts in the results, making the shooting results more accurate.

[0038] As Figures 1-6As shown in the figure, the working principle of the present invention is as follows: When performing a brain CT scan for each patient, a set of cotton fabric covers 412 after sterilization and disinfection is replaced, and then the replaced cotton fabric covers 412 are uniformly washed, sterilized and disinfected. By replacing the cotton fabric covers 412, the comfort of the second arc-shaped airbag 408 fitting the patient's head with the first arc-shaped airbag 403 is further enhanced, and at the same time, it is cleaner and more hygienic, making the device healthier and more hygienic, avoiding cross-infection of bacteria. The patient can lie flat on the CT scanning bed board 1, and the patient's head is horizontally placed inside the T-shaped frame 3, and the fitting component 4 and the clamping component 5 are coordinated to stably limit the patient's head on the premise of ensuring comfort. It can also ensure that when the patient lies on the side, the patient's head can still be placed inside the T-shaped frame 3. Similarly, the fitting component 4 and the clamping component 5 are coordinated to stably limit the patient's head on the premise of ensuring comfort. When the patient lies down and the patient's head is placed inside the T-shaped frame 3, the present invention automatically fits the patient's head and stably limits the patient's head, no longer requiring manual operation, making the device structure simple and the operation more convenient. Specifically, when the patient changes from the supine position to the lateral position, the upper end of the T-shaped frame 3 can rotate 90 degrees around the rotating shaft 6, so as to ensure that when the patient lies on the side, the patient's head can still be placed inside the T-shaped frame 3. Similarly, the fitting component 4 and the clamping component 5 are coordinated to stably limit the patient's head on the premise of ensuring comfort. Compared with the prior art, the use scenarios and the scope of use are more extensive. When the patient's head is placed on the first arc-shaped airbag 403, the first arc-shaped airbag 403 is squeezed, and the gas inside the first arc-shaped airbag 403 is squeezed and enters into the two second arc-shaped airbags 408 through the air pipe 411. Finally, the two second arc-shaped airbags 408 and the first arc-shaped airbag 403 fully fit the patient's head, ensuring comfort. When the patient's head squeezes the first arc-shaped airbag 403, the first driving rod 511 is synchronously squeezed. The first driving rod 511 drives the gear bar 509 to slide downward. Since the gear bar 509 meshes with the second gear 508, the second gear 508 rotates. The second gear 508 drives the first gear 507 to rotate. The first gear 507 drives the pull rod 503 to rotate. During the rotation of the pull rod 503, the pull column 504 is driven to rotate. When the pull column 504 rotates around the auxiliary shaft 502, in cooperation with the slide rail 506, the two slide rails 506 move closer to the middle. The slide rails 506 pull the two second driving rods 505 to contract toward the middle, thereby driving the two second arc-shaped blocks 407 to move closer to the middle synchronously, and further realizing the clamping and limiting of the patient's head. Finally, when taking a brain CT, the shaking of the patient's head is avoided from generating artifacts in the results, making the shooting results more accurate.

[0039] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special explanation and limitation.
