Description

Technical Field

[0001] The present invention relates to the technical field of magnetic resonance, and specifically to a head scanning fixing frame. Background Art

[0002] When a patient undergoes a head scan, the patient needs to change the scanning angle according to the instructions of medical staff. The patient's own rotation will cause inaccurate scanning positions, interfering with the medical staff's diagnosis of the diseased area. Moreover, multiple rotations of the head angle will also prolong the scanning time and reduce the work efficiency of medical staff. Therefore, a fixing frame is needed to fix the patient's head.

[0003] In this regard, Patent CN215191536U discloses a radiology magnetic resonance head fixing device that can drive a limiting plate to move up and down by a slider, and can limit and fix the upper surface of the head by the limiting plate, effectively fixing heads of different sizes by the fixing device.

[0004] However, due to substances such as facial oil or dandruff carried by the patient himself falling and adhering to parts such as the headrest and the fixing frame, when used next time, it will not only affect the scanning results, but also the bacteria or viruses that the patient may carry will cross-infect the next patient. Currently, it is necessary for the staff to clean the disposable medical paper covers that have been used on the headrest and the fixing frame part after each patient's scan, and finally put on the disposable medical paper covers. Each time after use, the staff needs to clean it, which greatly increases the labor of the staff. Moreover, most of the existing fixing brackets use telescopic rods or motors as the drive, and there will be a rustling sound during mechanical movement when adjusting the position, which makes the patient feel nervous, increases the patient's psychological pressure, and affects the accuracy of head scanning.

[0005] Therefore, we propose a head scanning fixing frame to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a head scanning fixing frame to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A head scanning fixing frame includes a scanning bed. A head scanner is installed at one end of the scanning bed. On both sides inside the head scanner, side brackets are installed, and a base fixed to the scanning bed is installed at the lower part. An inflatable headrest assembly is installed on the base, and an inflatable head fixing assembly is connected to the side brackets. A disposable film sleeve set one is sleeved on the surface of the inflatable headrest assembly, and a disposable film sleeve set two is sleeved on the inflatable head fixing assembly. One side of two adjacent disposable film sleeves one in the disposable film sleeve set one is connected to each other by a pull cord one to form a series structure. The disposable film sleeve set two includes several disposable film sleeves two. One side of two adjacent disposable film sleeves two in the disposable film sleeve set is connected to each other by a pull cord two to form a series structure. Initially, each disposable film sleeve one is sleeved together, and the disposable film sleeves two are sleeved together.

[0009] The outermost pull cord one and pull cord two are both connected to a film recycling assembly.

[0010] When the head scanning fixing frame is in use, after the patient lies on the scanning bed, the inflatable headrest assembly and the inflatable head fixing assembly are inflated to fix the patient's head. When the patient's scanning is completed, the inflatable headrest assembly and the inflatable head fixing assembly are deflated. At the same time, the film recycling assembly pulls the pull cord one and the pull cord two to pull out the outermost disposable film sleeve one and disposable film sleeve two, exposing the second outermost disposable film sleeve one and disposable film sleeve two.

[0011] For further improvement, a small silent air pump is installed on one side of the side bracket. The small silent air pump is connected to the inflatable headrest assembly and the inflatable head fixing assembly through an air delivery pipeline.

[0012] For further improvement, the inflatable headrest assembly includes a skeleton fixed on the base. A headrest airbag is installed on the skeleton. The base is connected to the inner side of the top of the headrest airbag by a tension spring one.

[0013] For further improvement, the inflatable head fixing assembly includes a telescopic airbag. A sponge push plate is fixed at the inner end of the telescopic airbag. The disposable film sleeve set two is sleeved on the sponge push plate. The outer end of the telescopic airbag is connected to the side bracket through a cross bar. Both ends inside the telescopic airbag are connected by a tension spring two.

[0014] For further improvement, the inner side of the sponge push plate is arc-shaped.

[0015] For further improvement, the film recycling assembly includes a barrel body. A hopper barrel is installed at the front end of the barrel body. A winch is radially passed through the barrel body.

[0016] Further improvement: A gas recovery power assembly is installed in cooperation with the film recovery assembly. The gas recovery power assembly includes a rotating shaft connected to a winch. The rotating shaft is connected to an outer shell ring. A number of rotating rods are evenly and fixedly connected to the rotating shaft along the circumferential direction. The rotating rods are connected to fan blades. A blowing pipe is installed in cooperation with the fan blades. The blowing pipe is connected to the headrest airbag () of the inflatable headrest assembly and the telescopic airbag of the inflatable head fixing assembly through an electronic valve.

[0017] After the patient's scan is completed, the electronic valve is opened, and the gas in the headrest airbag () and the telescopic airbag triggers the fan blades, causing the winch to rotate, pulling out the outermost disposable film sleeve one and disposable film sleeve two, and exposing the second outermost disposable film sleeve one and disposable film sleeve two.

[0018] Further improvement: A hinge is provided on one side of the back of the barrel body. A sealing cover is installed on one side of the hinge. A handle is installed at the front end of the sealing cover. A disinfectant atomizer is installed at the front end of the barrel body.

[0019] Further improvement: The hopper barrel faces the inflatable headrest assembly and the inflatable head fixing assembly. The sealing cover is rotatably connected to the barrel body through a hinge. The hopper barrel is connected to and communicates with the barrel body. The disinfectant atomizer is directly facing the inflatable headrest assembly and the inflatable head fixing assembly.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. After the patient's scan is completed, the gas filled in the headrest airbag and the telescopic airbag when fixing the patient's head by a small air pump is used. Utilizing the elasticity of the materials of the headrest airbag and the telescopic airbag itself and the pulling force of the tension spring one and the tension spring two, the space is compressed to push the gas, driving the film recovery assembly to automatically clean the disposable medical paper sleeve that has been used for the headrest and the fixing frame part, and spraying atomized disinfectant for disinfection treatment, eliminating the need for staff to clean every time after use, greatly reducing the labor of the staff.

[0022] 2. Avoid the rustling sound during mechanical movement when using a telescopic rod or a motor as the drive. Use a silent air pump to fix the patient's head with gas, reduce the sense of tension of the patient, relieve the psychological pressure of the patient, and improve the accuracy of head scanning.

[0023] 3. Facilitate the quick cleaning of the collected disposable film sleeve, convenient for maintenance, and high in practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figure 1-8, the present invention provides a technical solution: a head scanning fixing frame, including a head scanner 1, a scanning bed 10 is installed on one side of the head scanner 1, a side bracket 11 is arranged on the outer wall of one side of the scanning bed 10, a base 12 is installed at one end of the scanning bed 10, a small silent air pump 13 is installed on one side of the side bracket 11, and an air delivery pipe 14 is arranged at the output end of the small silent air pump 13; and

[0035] an inflatable headrest assembly 2, the inflatable headrest assembly 2 is arranged on the top of the scanning bed 10, the inflatable headrest assembly 2 is used for inflating to support the patient's head, and providing kinetic energy to the gas recovery power assembly 5 when deflating; and

[0036] an inflatable head fixing assembly 3, the inflatable head fixing assembly 3 is installed inside the side bracket 11, the inflatable head fixing assembly 3 is used for fixing the patient's head from both sides, and providing kinetic energy to the gas recovery power assembly 5 when deflating; and

[0037] a film recovery assembly 4, the film recovery assembly 4 is installed on the top of the base 12, the film recovery assembly 4 is used for recovering the disposable film sleeve two 34 and the disposable film sleeve one 23 sleeved on the outer surfaces of the inflatable headrest assembly 2 and the inflatable head fixing assembly 3; and

[0038] a gas recovery power assembly 5, the gas recovery power assembly 5 is arranged on one side of the film recovery assembly 4, and the gas recovery power assembly 5 utilizes the kinetic energy provided by the inflatable headrest assembly 2 and the inflatable head fixing assembly 3 when deflating after inflation to drive the film recovery assembly 4 to recover the disposable film sleeve two 34 and the disposable film sleeve one 23.

[0039] Furthermore, (such as Figure 4) The number of small silent air pumps 13 and air delivery pipes 14 is set to two groups, and the number of inflatable head fixing assemblies 3 is set to two groups. The two groups of small silent air pumps 13 and air delivery pipes 14 are respectively connected to both sides of the two groups of inflatable headrest assemblies 2 and one end of the two groups of head fixing assemblies 3. During actual use, first, let the patient lie flat on the scanning bed 10 with the head flat on the inflatable headrest assembly 2. Then, the doctor starts the small silent air pump 13, and the small silent air pump 13 starts to inflate. Through the air delivery pipe 14, the headrest airbag 22 in the inflatable head fixing assembly 3 and the telescopic airbag 31 in the inflatable head fixing assembly 3 are inflated. The headrest airbag 22 and the telescopic airbag 31 start to expand. The headrest airbag 22 stores energy for the first tension spring 21, and the telescopic airbag 31 stores energy for the second tension spring 32. At the same time, when the headrest airbag 22 and the telescopic airbag 31 start to expand, the headrest airbag 22 supports the patient's head, and the telescopic airbag 31 pushes the sponge push plate 33 from both sides closer to the patient's head until it clamps the patient's head to fix it. The sponge push plate 33 is set to be arc-shaped to better fit the patient's head. The sponge material can buffer between the head and the telescopic airbag 31 to prevent clamping the head too tightly and causing discomfort to the patient. After the patient's head is fixed, the doctor starts to operate the head scanner 1 to position and scan the patient's head;

[0040] Furthermore, (such as Figure 4 , Figure 5 and Figure 6)The inflatable headrest assembly 2 includes a framework 20. The framework 20 is installed on the top of the scanning bed 10. A first tension spring 21 is installed on the top of the framework 20. A headrest airbag 22 is sleeved on the outer surfaces of the framework 20 and the first tension spring 21. A first disposable film sleeve 23 is sleeved on the outer surface of the headrest airbag 22. A first pull rope 24 is installed at the top of the first disposable film sleeve 23. When the headrest airbag 22 is inflated, it will store energy for the first tension spring 21. Both sides of the headrest airbag 22 are connected to a small silent air pump 13 through an air delivery pipeline 14. The first disposable film sleeve 23 is provided in multiple groups, and a certain length of the first pull rope 24 is installed between each group of the first disposable film sleeve 23. The inflatable head fixing assembly 3 includes a cross bar 30. One end of the cross bar 30 is installed inside the side bracket 11. A telescopic airbag 31 is installed at one end of the cross bar 30. A second tension spring 32 is sleeved on the inner wall of the telescopic airbag 31. A sponge push plate 33 is provided at the end of the telescopic airbag 31. A second disposable film sleeve 34 is sleeved on the outer surface of the sponge push plate 33. A second pull rope 35 is installed at one end of the second disposable film sleeve 34. The telescopic airbag 31 will extend or contract inward when inflated and deflated. When the telescopic airbag 31 is inflated, it will store energy for the second tension spring 32. One side of the sponge push plate 33 is arc-shaped. The second disposable film sleeve 34 is provided in multiple groups, and a certain length of the second pull rope 35 is installed on each group of the second disposable film sleeve 34. During actual use, the length of each first pull rope 24 and the second pull rope 35 is exactly the distance from the winch 50 to the headrest airbag 22 and the sponge push plate 33. After each group of the first disposable film sleeve 23 and the second disposable film sleeve 34 is recycled, a new group will exactly remain on the surfaces of the headrest airbag 22 and the sponge push plate 33. At the same time, the first pull rope 24 and the second pull rope 35 are exactly straightened with the winch 50, without affecting the space of the patient's head;

[0041] Furthermore, (such as Figure 7 and Figure 8)A disinfectant atomizer 45 is installed at the front end of the cylinder body 40. The gas recovery power assembly 5 includes a winch 50. One end of the winch 50 is installed with a rotating shaft 51. A number of groups of rotating rods 52 are installed at the end of the rotating shaft 51. A fan blade 53 is arranged at the end of the rotating rod 52. An outer shell ring 54 is sleeved on the outer surface of the rotating shaft 51. A blowing pipe 55 is installed at the bottom of the outer shell ring 54. An electronic valve 56 is installed at the end of the blowing pipe 55. The winch 50 and the rotating shaft 51 are rotationally connected to the cylinder body 40. One ends of the first pull rope 24 and the second pull rope 35 are connected to one side of the winch 50. The end opening of the blowing pipe 55 is obliquely inserted at the bottom of the outer shell ring 54. The end opening of the blowing pipe 55 is directly facing the fan blade 53. The other end of the blowing pipe 55 is connected to the headrest airbag 22 and is in communication. The hopper 41 faces the inflatable headrest assembly 2 and the inflatable head fixing assembly 3. The sealing cover 43 is rotationally connected to the cylinder body 40 through a hinge 42. The hopper 41 is connected to the cylinder body 40 and is in communication. (The function of the hopper 41 is to expand the space at the entrance of the cylinder body 40, so that the first disposable film sleeve 23, the second disposable film sleeve 34, the first pull rope 24 and the second pull rope 35 can accurately enter the winch 50 inside the cylinder body 40 and be collected). The disinfectant atomizer 45 is directly facing the inflatable headrest assembly 2 and the inflatable head fixing assembly 3. During actual use, after the patient's head scanning work is completed, the head scanner 1 is turned off. The patient gets up from the scanning bed 10. Then the doctor opens the electronic valve 56. At this time, the headrest airbag 22 and the telescopic airbag 31 quickly retract under the elastic force of their own airbag materials and the pulling force of the first tension spring 21 and the second tension spring 32. When retracting, the air in the headrest airbag 22 and the telescopic airbag 31 will be blown into the inside of the outer shell ring 54 in the gas recovery power assembly 5 through the blowing pipe 55 opened by the electronic valve 56. Since the blowing pipe 55 is just inclined and directly facing the vicinity of the fan blade 53, the gas starts to blow a number of groups of fan blades 53. When the fan blades 53 are blown by the gas, they drive the rotating rods 52 to drive the rotating shaft 51 to rotate. The rotating shaft 51 starts to drive the winch 50 to rotate. When the winch 50 rotates and tightens, it pulls the first pull rope 24 and the second pull rope 35, and at the same time pulls the first disposable film sleeve 23 and the second disposable film sleeve 34 onto the winch 50 to be wound up. The first disposable film sleeve 23 and the second disposable film sleeve 34 have the characteristics of being soft and light, so they are easily wound up by the winch 50, completing the automatic collection of the used first disposable film sleeve 23 and the second disposable film sleeve 34. Finally, the doctor starts the disinfectant atomizer 45 to atomize and spray the disinfectant on the new headrest airbag 22, the surface of the new first disposable film sleeve 23, the second disposable film sleeve 34 and the scanning bed 10, as well as the side brackets 11, the telescopic airbag 31 and other places that the patient may come into contact with to complete the disinfection work;

[0042] Furthermore, (such as Figure 7) The film recycling component 4 includes a barrel body 40. A hopper barrel 41 is installed at the front end of the barrel body 40. A hinge 42 is provided on one side of the back of the barrel body 40. A sealing cover 43 is installed on one side of the hinge 42. A handle 44 is installed at the front end of the sealing cover 43. After the disposable film sleeve one 23 and the disposable film sleeve two 34 are used up, the staff pulls the handle 44 on the sealing cover 43 to open the sealing cover 43, and cleans the used disposable film sleeve one 23, the disposable film sleeve two 34, the pull rope one 24 and the pull rope two 35 wound on the winch 50. Then, a new set of disposable film sleeve one 23 and disposable film sleeve two 34 are sleeved on the headrest airbag 22 and the sponge push plate 33. At the same time, one ends of the pull rope one 24 and the pull rope two 35 are fixed on the winch 50. Finally, the sealing cover 43 is closed to complete the preparation work.
