Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a head fixing device for medical image scanning. Background Art

[0002] Medical imaging head scan is an important diagnostic method used to detect and evaluate various diseases and lesions of the head. It is a routine computer tomography examination technology of the brain and is often used for emergency patients. It does not require the injection of contrast agents. It routinely uses non-spiral transverse scans with the scanning angle parallel to the auditory canthus line and the scanning range is from the foramen magnum to the top of the skull.

[0003] When a patient lies on a scanning bed for a head scan, the patient's head is usually required to be placed flat so that the eyes are facing upward. In specific operations, due to limitations such as hospital size or medical equipment, such as county-level hospitals, medical staff generally use a U-shaped support structure to fix the patient's head to meet the scanning requirements. However, during use, when the patient uses the U-shaped support structure to fix the head, the position of the patient's neck and back close to the neck will be as close to the movable bed board of the scanning bed as possible under the action of the patient's body gravity, which makes the patient's head easy to tilt upward, resulting in an uneven head placement problem. At the same time, due to the different head contours of patients, the U-shaped support structure cannot perfectly adapt to the heads of different patients to achieve accurate positioning. Therefore, the help of medical staff is needed before scanning to adjust the patient's head position to assist in positioning. Therefore, the utility model provides a head fixing device for medical imaging scanning to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a head fixing device for medical image scanning. By setting a fixing component, the patient can not only quickly and accurately position his head to the scanning area, but also fit the patient's head contour, which has a certain massage effect on the patient. The structure of the fixing component is closely connected and complementary in function, and the overall structure of the plate body is made of ABS plastic material, which is not only low in cost, but also simple in processing technology and easy to manufacture.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0010] Optionally, a C-shaped elastic plate is fixedly connected to the outer wall of the elastic soft pad, and the other ends of the two C-shaped elastic plates are fixedly connected to the rubber head pad.

[0011] Optionally, elastic clips are fixedly connected to the outer walls of the two C-shaped elastic plates, and a limiting groove is formed in the outer wall of the rubber head pad.

[0012] Optionally, a plurality of second segmented grooves are formed in the limiting groove, and a limiting elastic plate, two groups of first support plates and two groups of second support plates are respectively fixedly connected to the outer wall of the limiting groove.

[0013] Optionally, a massage hose is fixedly connected to one end of the first support plate, and a plurality of massage grooves are formed in the massage hose.

[0015] Optionally, one end of the limiting elastic plate is fixedly connected to the rubber head pad, and a plurality of third segmented grooves are formed in the limiting elastic plate.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above solution, by setting the fixing component, the patient can not only quickly and accurately position his own head to the scanning area, but also fit the head contour of the patient, which has a certain massage effect on the patient. The structure of the fixing component is closely connected and complements each other in function, and the overall structure of the plate body is made of ABS plastic material, which not only has a low cost, but also has a simple processing technology and is easy to manufacture.

[0018] By setting the fixing plate, when the fixing plate is installed on the scanning bed, the fixing plate can not only be fixed by relying on the pressure of the patient himself, but also the stability and firmness of the fixing plate can be improved by relying on the clamping force of the lower clamping plate and the inner clamping plate. In addition, lightweight grooves are provided on the fixing plate, the upper clamping plate and the lower clamping plate, which can not only reduce the weight of the fixing plate, making it more labor-saving for the user during actual operation, but also reduce the manufacturing cost.

[0019] By setting the elastic support plate, elastic soft pads and C-shaped elastic plate, since both elastic soft pads are screwed to one end of the elastic support plate by nuts, and the elastic soft pads are cashew-shaped and provided with second elastic holes, the comfort of the elastic soft pads is improved. When a patient uses it, it can effectively fix the patient's head without causing discomfort to the patient. When the patient leaves the scanning bed after the scan, the C-shaped elastic plate returns to its original shape under the action of elasticity. Cooperating with the elastic soft pads and the elastic support plate, it returns to the initial state, can quickly provide services for the next patient, and improves the efficiency of medical staff.

[0020] By setting the rubber head pad, not only can it provide a certain positioning effect when fixing the patient's head, but also, with the cooperation of the second segmented groove, the first elastic plate, the second elastic plate, the massage hose and the elastic tube, it can better fit the head contours of different patients and has a certain massage effect, improving the comfort of the patient and preventing the patient from moving involuntarily due to discomfort when the head is fixed, resulting in a failed scan.

[0035] As Figures 1 to 5 shown, an embodiment of the present utility model provides a head fixing device for medical image scanning, including a fixing plate 1. An upper clamping plate 101 and a lower clamping plate 103 are fixedly connected to the outer wall of the fixing plate 1. A semi-circular pad 102 is fixedly connected to the outer wall of the upper clamping plate 101. A plurality of first elastic holes 105 are formed in the semi-circular pad 102, and a plurality of first segmented grooves 106 are formed in the outer wall of the semi-circular pad 102. Three linearly arranged inner clamping plates 104 are fixedly connected to the outer wall of the lower clamping plate 103; a fixing component is used to assist in fixing the patient's head on the scanning bed, and the fixing component is connected to the fixing plate 1. Specifically, the semi-circular pad 102 is semi-circular in shape and is made of rubber. The semi-circular pad 102 fixedly connected to the outer wall of the upper clamping plate 101, with the plurality of first elastic holes 105 and the plurality of first segmented grooves 106 respectively formed therein, will cause the first elastic holes 105 to deform inward under the action of pressure, and cooperate with the first segmented grooves 106, so that the outer wall can adapt to fit the contours of different patients' necks. The upper clamping plate 101 and the lower clamping plate 103 provided in this application are both fixedly connected to the outer wall of the fixing plate 1. When installing the fixing plate 1 on the scanning bed, not only can the fixing plate 1 be fixed by means of the patient's own pressure, but also the stability and firmness of the fixing plate 1 can be improved by means of the clamping force of the lower clamping plate 103 and the inner clamping plates 104. The three linearly arranged inner clamping plates 104 on the lower clamping plate 103 can abut against the bottom outer wall of the bedplate of the scanning bed, which can not only adapt to different thicknesses of a certain bedplate, but also increase the clamping friction and are not easy to fall off. In addition, lightweight grooves are provided on the fixing plate 1, the upper clamping plate 101 and the lower clamping plate 103, which can not only reduce the weight of the fixing plate 1, making it more labor-saving for the user during actual operation, but also reduce the manufacturing cost.

[0036] As an implementation manner in this embodiment, such as Figures 1 to 5As shown, the fixing assembly includes two elastic support plates 2 screwed on the outer wall of the fixing plate 1 through nuts, one end of the two elastic support plates 2 are screwed on two elastic pads 3 through nuts, and the elastic pads 3 are provided with a plurality of second elastic holes 301, and the outer walls of the other ends of the two elastic support plates 2 are fixedly connected with elastic plates 201, and the outer walls of the elastic pads 3 are fixedly connected with C-shaped elastic plates 5, and the outer walls of the two C-shaped elastic plates 5 are fixedly connected with elastic clips 501, and one end of the two C-shaped elastic plates 5 are fixedly connected to the rubber head pad 4. Specifically, the two elastic support plates 2 included in the fixing assembly are symmetrically screwed on the outer walls of the fixing plate 1 on both sides through nuts, and the elastic support plates 2 are roughly in the shape of "C" with a section being a straight plate, which is plastic. The material has a certain elasticity. One ends of the two elastic support plates 2 are screwed to the outer walls of the two elastic pads 3 through nuts. There are four elastic pads 3 in total, two in each group, symmetrical about the center of the fixed plate. The other ends of the two elastic support plates 2 are fixedly connected to one end of the elastic plate 201 on the outer wall on the side close to the fixed plate 1, and the other ends of the two elastic plates 201 are fixedly connected to the inner wall of the rubber head pad 4. The elastic plate 201 is in an "S" shape and is made of plastic. The elastic pad 3 is in a cashew nut shape, which is made of rubber and has a second elastic hole 301. One ends of the two C-shaped elastic plates 5 are fixedly connected to the outer walls of the two elastic pads 3, and the other ends of the two C-shaped elastic plates 5 are fixedly connected to the outer wall of the rubber head pad 4. An elastic clip 501 is fixedly connected to the outer wall of the end of the C-shaped elastic plate 5 close to the rubber head pad 4, wherein the C-shaped elastic plate 5 is in a "C" shape, and the elastic clip 501 is roughly in a lying "S" shape, with the end away from the C-shaped elastic plate 5 slightly tilted, both of which are made of plastic. When the patient uses the device and lies on the scanning bed, the end of the elastic support plate 2 with the straight plate will be pressed down under the action of the gravity of the head, and then the "S"-shaped elastic plate 201 will deform toward the middle at both ends under pressure, and the other end of the elastic support plate 2 will also change due to the effect of the lever principle. Since it is in a "C" shape, its other end will drive the elastic cushion 3 to move toward the center of the rubber head pad 4, so that the elastic cushion 3 fits the patient's head. The elastic holes on the cashew-shaped elastic pad 3 will deform inwardly as the patient's head contour is squeezed, making it more suitable for the patient's head, especially there is a gap between each group of elastic pads 3, which is just located at the patient's ears, so that the patient's ears will not be squeezed and covered. When the elastic pad 3 fits the patient's head, the end close to the rubber head pad 4 will move backward, which will drive one end of the C-shaped elastic plate 5 fixedly connected to its outer wall to deform outward, and the deformation rate is not large. When the patient leaves the scanning bed after the scan is completed, the C-shaped elastic plate 5, the elastic pad 3 and the elastic support plate 2 can not only return to the initial state under the action of elasticity, but can also quickly provide services for the next patient. Since the device is not a disposable product, in order to keep it clean,A medical spunbond fabric needs to be placed on the rubber head pad 4 for easy washing and replacement. The outer wall of the protruding end of the elastic clip 501 abuts against the outer wall of the rubber head pad 4, and the medical spunbond fabric can be clamped, so that the patient will not drop the medical spunbond fabric during use. The above structural settings can not only fix the patient's head, but also improve the patient's comfort during use and relieve the work pressure of medical staff at the same time.

[0037] A rubber head pad 4 is fixedly connected to the outer wall of the fixed plate 1. A limiting groove 401 is formed on the outer wall of the rubber head pad 4. A number of second segmented grooves 402 are formed on the limiting groove 401. Limiting elastic plates 6, two groups of first support plates 403 and two groups of second support plates 405 are respectively fixedly connected to the outer wall of the limiting groove 401. One end of the first support plate 403 is fixedly connected to a massage hose 404. A number of massage grooves 407 are formed on the massage hose 404. One end of the second support plate 405 is fixedly connected to an elastic tube 406. One end of the limiting elastic plate 6 is fixedly connected to the rubber head pad 4. A number of third segmented grooves 601 are formed on the limiting elastic plate 6. Specifically, the rubber head pad 4 is in the shape of a lying "P", hollow in the middle, made of rubber, and has a certain elasticity. The rubber head pad 4 is fixedly connected to the outer wall at the center of the top of the fixed plate 1. A circular limiting groove 401 is formed on the outer wall of the top end of the rubber head pad 4. A number of second segmented grooves 402 are evenly formed on the outer wall of the circular limiting groove 401 with respect to the central part. At the same time, one end of the two groups of first support plates 403 is fixedly connected to the outer wall of the limiting groove 401, and the other end is fixedly connected to the outer wall of the massage hose 404. The first support plate is in the shape of a "C" and is made of plastic. The massage hose 404 is in the shape of a hollow cylinder and a number of massage grooves 407 are formed on its outer wall, and it is made of rubber. One end of the second support plate 405 is fixedly connected to the outer wall of the limiting groove 401, and the other end is fixedly connected to the outer wall of the elastic tube 406. The second elastic plate is in the shape of a cuboid and is made of plastic. The elastic tube 406 is generally in the shape of a hollow cylinder, but both sides are concave towards the center of the elastic tube 406 and it is made of rubber. One end of the limiting elastic is fixedly connected to the outer wall of the limiting groove 401, and the other end is fixedly connected to the rubber head pad 4 and is made of plastic. When the patient lies on the scanning bed, the head can be accurately positioned according to the limiting groove 401 on the rubber head pad 4. At this time, the top of the patient's head will abut against the outer wall of the limiting elastic plate 6 to assist in positioning. Since a number of third segmented grooves 601 are formed on the limiting elastic plate 6, when the patient's head is too large, the protrusion on the limiting elastic plate 6 that abuts against the patient's head will deform towards the front of the top of the head. Under the action of the head pressure, the second segmented grooves 402 will deform according to the contours of both sides of the patient's head. At this time, the inner wall of the rubber head pad 4 will abut against the outer wall of the end of the C-shaped support plate with a straight plate, driving it to displace downward. One end of the first support plate 403 will deform towards the other end after being stressed. The pressure-receiving surface of the massage hose 404 fixedly connected to one end of the first support plate 403 will deform towards its own center part, and will also displace along the direction of the patient's head contour. During the displacement process, a number of massage grooves 407 formed on its outer wall will provide a certain massage effect to the patient. The elastic tube 406 fixedly connected to one end of the second support plate 405 will also, while being stressed, the two sides concave towards the center of the elastic tube 406 will bend inwardly.To provide a certain buffering effect for the patient, the above structural settings can not only provide a certain positioning effect when fixing the patient's head, but also, in cooperation with the second segmented groove 402, the first support plate 403, the second support plate 405, the massage hose 404 and the elastic tube 406, better conform to the head contours of different patients, and have a certain massage function, improving the comfort of the patient and preventing the patient from having an uncomfortable feeling when the head is fixed, thus causing involuntary movement of the body and resulting in a failed scan.

[0038] The working principle of the technical solution provided by the present utility model is as follows: When in use, when the fixing plate 1 is installed on the scanning bed, not only can the fixing plate 1 be fixed by means of the pressure of the patient himself, but also the clamping force of the lower clamping plate 103 and the inner clamping plate 104 can be used to improve the stability and firmness of the fixing plate 1. Among them, the semi-circular pads 102 fixedly connected to the outer wall of the upper clamping plate 101, and the first elastic holes 105 and the first segmented grooves 106 respectively opened, will cause the first elastic holes 105 to deform inward under the action of pressure, and cooperate with the first segmented grooves 106, so that the outer wall can adapt to fit the contours of the necks of different patients. The three inner clamping plates 104 linearly arranged and distributed on the lower clamping plate 103 can abut against the bottom outer wall of the bed board of the scanning bed, which can not only adapt to different thicknesses of a certain bed board, but also increase the clamping friction and is not easy to fall off. In addition, lightweight grooves are provided on the fixing plate 1, the upper clamping plate 101 and the lower clamping plate 103, which can not only reduce the weight of the fixing plate 1 and make it more labor-saving for the user during actual operation. When the patient lies on the scanning bed, the head can be accurately positioned according to the limiting grooves 401 on the rubber head pad 4. At this time, the top of the patient's head will abut against the outer wall of the limiting elastic plate 6 to assist in positioning. Since a number of third segmented grooves 601 are provided on the limiting elastic plate 6, when the patient's head is too large, the protrusion of the limiting elastic plate 6 abutting against the patient's head will deform forward to the front of the head. Under the action of the head pressure, the second segmented groove 402 will deform according to the contours on both sides of the patient's head. At this time, the inner wall of the rubber head pad 4 will abut against the outer wall of the end of the C-shaped support plate with a straight plate, driving it to displace downward, and one end of the first support plate 403 will deform toward the other end after being stressed. The pressure-receiving surface of the massage hose 404 fixedly connected to one end of the first support plate 403 will deform toward the center of itself, and will also displace along the direction of the contour of the patient's head. During the displacement process, a number of massage grooves 407 provided on its outer wall will provide a certain massage effect for the patient. The elastic tube 406 fixedly connected to one end of the second support plate 405 will also deform inward with both sides concave toward the center of the elastic tube 406 while being stressed, providing a certain buffering effect for the patient. After lying on the scanning bed, under the action of the head gravity, the end of the elastic support plate 2 with a straight plate will be pressed down. Subsequently, the two ends of the "S"-shaped elastic plate 201 will deform toward the middle under the pressure, and the other end of the elastic support plate 2 will also change due to the action of the lever principle. Since it is in a "C" shape, the other end will drive the elastic soft pad 3 to displace toward the center of the rubber head pad 4, making the elastic soft pad 3 fit the patient's head. Among them, the elastic holes on the cashew-shaped elastic soft pad 3 will deform inward with the extrusion of the patient's head contour, making it more suitable for the patient's head. When the elastic soft pad 3 fits the patient's head, the end close to the rubber head pad 4 will move backward, driving one end of the C-shaped elastic plate 5 fixedly connected to its outer wall to deform outward, and the deformation rate is not large.When the patient leaves the scanning bed after the scan, under the action of elasticity, the C-shaped elastic plate 5, the elastic cushion 3 and the elastic support plate 2 can not only return to the initial state, but also quickly provide services for the next patient. Since this device is not a disposable item, in order to maintain cleanliness, a medical spunbond fabric needs to be placed on the rubber head pad 4 for easy washing and replacement. The outer wall of the protruding end of the elastic clip 501 abuts against the outer wall of the rubber head pad 4, and the medical spunbond fabric can be clamped, so that the patient will not drop the medical spunbond fabric during use.

However, those skilled in the art can fully understand the present utility model without these detailed descriptions.
