Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a head fixation structure for patient testing. Background Technology

[0002] The radiology department is a crucial department in hospitals that utilizes medical imaging technology for patient diagnosis and auxiliary treatment. Its core function is to capture images of the internal structures of the human body using various imaging devices, providing clinicians with key information for disease diagnosis, condition assessment, and treatment plan development. Radiology equipment is commonly used when examining areas such as the patient's head.

[0003] When examining a patient's head, the imaging examination relies on the equipment to accurately scan human tissues, which requires the patient's head to remain stable. However, some patients (such as elderly or young patients) cannot ensure head stability, leading to blurry scan data and motion artifacts. This necessitates rescanning and reduces efficiency.

[0004] Therefore, this utility model provides a head fixation structure for patient testing. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The patient examination head fixation structure of this utility model includes an examination bed; it also includes: a fixing frame, two of which are symmetrically installed on both sides of the examination bed, a sliding frame slidably connected inside the fixing frame, a plurality of through slots for inserting rods are opened on one side of the fixing frame, and a slot adapted to the insert rod is opened at one end of the sliding frame; an extension block that slides inside the sliding frame, an arc-shaped clamping plate is fixedly installed at one end of the extension block, and a gasket is installed on one side of the clamping plate.

[0007] Furthermore, a protrusion is fixedly installed inside the sliding frame, and a rubber positioning ball is wedged at the bottom of the protrusion. Several positioning grooves that are adapted to the positioning ball are opened at the top of the sliding frame.

[0008] Furthermore, one side of the clamping plate has two symmetrically arranged rectangular grooves, and a disposable protective pad is laid on the clamping plate through the rectangular grooves; one side of the clamping plate has several limiting grooves, and limiting posts are inserted into the limiting grooves.

[0009] Furthermore, the limiting post gradually shrinks from the end closer to the sliding frame to the end farther away from the sliding frame. The limiting post is made of rubber material, and one end of the sliding frame has a groove that matches the limiting post.

[0010] Furthermore, the sliding frame is sealed and slidably connected within the fixed frame. An air inlet pipe with a one-way valve is fixedly installed on the top of the sliding frame and communicates with the interior. An air outlet pipe with a one-way valve is fixedly installed on the bottom of the sliding frame and communicates with the interior. One end of the air outlet pipe is connected to the air outlet frame at the bottom of the clamping plate. A plurality of air outlet holes are opened on one side of the air outlet frame.

[0011] Furthermore, a filter screen is fixedly installed inside the air outlet of the air outlet frame, and a trumpet-shaped guide column is fixedly installed on one side of the filter screen. The guide column is hollow.

[0012] Furthermore, a U-shaped connecting rod is fixedly installed between the two limiting posts.

[0013] The beneficial effects of this utility model are as follows: 1. The head fixation structure for patient examination described in this utility model uses a clamping plate with a pad to fix the patient's head. The pad acts as a buffer and protects the patient's head, preventing discomfort caused by direct contact between the rigid clamping plate and the patient's head. The designed structure effectively clamps the patient's head and allows for timely adjustment of the clamping plate's position according to different patients' needs, thus expanding the clamping plate's applicability. Furthermore, the structure designed in this application ensures that the patient's head is fixed during the examination on the examination table, effectively preventing head movement and displacement that could lead to blurred scan data, motion artifacts, and the need for rescanning.

[0014] 2. The head fixation structure for patient testing described in this utility model utilizes a disposable pad to contact the patient, thereby avoiding direct contact between the patient and the pad, and effectively preventing cross-infection when the patient has an illness. After the previous patient finishes using the device, as the extension block moves towards the sliding frame with the clamping plate, the limiting post and other components such as the disposable pad move accordingly, causing one end of the limiting post to insert into the groove. Due to the shape design of the limiting post, it will be stuck in the groove. When the extension block returns to its original position with the clamping plate, the limiting post will not return to its original position. At this time, the disposable pad is no longer constrained and fixed, making it easy to remove the used disposable pad and expose the unused disposable pad for the next patient to use.

[0015] 3. The patient head fixation structure described in this utility model, when the patient finishes the examination and leaves the examination bed, compresses the internal gas as the extension block slides into the sliding frame. This causes the gas inside the sliding frame to enter the air outlet of the air outlet frame through the air outlet pipe and be ejected. Cleaning the area where the patient's head rests on the examination bed reduces the residue of impurities and prevents long or thick hair from forming high-density shadows or stripe artifacts in the image, thus affecting the accuracy of the examination. Timely cleaning also reduces the risk of cross-infection. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1 to 7As shown in the embodiment of this utility model, a head fixation structure for patient testing includes an examination bed 1; it also includes: a fixing frame 2, two of which are symmetrically installed on both sides of the examination bed 1; a sliding frame 3 slidably connected inside the fixing frame 2; a plurality of through slots 6 on one side of the fixing frame 2 for inserting rods 5; a slot 4 at one end of the sliding frame 3 that matches the insert rod 5; an extension block 7 that slides inside the sliding frame 3; an arc-shaped clamping plate 8 fixedly installed at one end of the extension block 7; and a gasket 9 installed on one side of the clamping plate 8. A protrusion 11 is fixedly installed inside the sliding frame 3; a rubber positioning ball 12 is wedged into the bottom of the protrusion 11; and a plurality of positioning grooves 10 that match the positioning ball 12 are opened on the top of the sliding frame 3.

[0021] During operation, when the patient is lying on the examination bed 1 for testing, the insertion rod 5 is pulled out from the through slot 6, which facilitates the sliding adjustment frame 3 in the fixed frame 2. The sliding frame 3, along with the extension block 7, clamping plate 8 and pad 9, moves to the appropriate position and stops. The insertion rod 5 is then reinserted into the slot 4 of the sliding frame 3 through the appropriate through slot 6 and fixed, so that the clamping plate 8 and pad 9 can be adapted to the position of different patients' heads.

[0022] Next, pull the extension block 7 inside the sliding frame 3, causing the extension block 7, along with the arc-shaped clamping plate 8 and the pad 9, to move towards the patient's head. As the sliding frame 3 moves, the positioning groove 10 continuously contacts the positioning ball 12, causing the positioning ball 12 to repeatedly enter and exit the positioning groove 10. When the extension block 7 reaches the appropriate position, it stops, and simultaneously, the positioning ball 12 enters the positioning groove 10 to assist in fixing the extension block 7. At this time, the clamping plate 8, along with the pad 9, is also fixed to the patient's head, and the pad 9 acts as a buffer and protects the patient's head, preventing discomfort caused by direct contact between the rigid clamping plate 8 and the patient's head.

[0023] The structure designed above effectively clamps the patient's head and allows for timely adjustment of the clamping plate 8 according to the needs of different patients, thereby expanding the applicability of the clamping plate 8. Simultaneously, the structure designed in this application ensures that the patient's head is fixed during the examination on the examination table 1, effectively preventing head movement and displacement that could lead to blurred scan data, motion artifacts, and the need for rescanning.

[0024] One side of the clamping plate 8 has two symmetrically arranged rectangular slots 13, and a disposable pad 14 passing through the rectangular slots 13 is laid on the clamping plate 8. Another side of the clamping plate 8 has several limiting slots 15, and limiting posts 16 are inserted into the limiting slots 15. The limiting posts 16 gradually decrease in size from the end closer to the sliding frame 3 to the end farther away from the sliding frame 3. The limiting posts 16 are made of rubber, and one end of the sliding frame 3 has a groove 17 that matches the limiting posts 16. A U-shaped connecting rod 23 is fixedly installed between two limiting posts 16.

[0025] During operation, several disposable pads 14 are laid on the clamping plate 8, with one side of each pad 14 in contact with the pad 9. Both ends of each pad pass through two rectangular grooves 13 and contact the back of the clamping plate 8. Then, a connecting rod 23, carrying two limiting posts 16, inserts portions of the disposable pads 14 into the limiting grooves 15 for fixation, thus securing the disposable pads 14 to the clamping plate 8. When the clamping plate 8 is used to clamp the patient's head, the disposable pads 14 contact the patient, preventing direct contact between the patient and the pad 9, effectively preventing cross-infection when the patient has an illness. After the previous patient finishes using the device, as the extension block 7 moves towards the sliding frame 3 along with the clamping plate 8, the limiting post 16 and other components such as the disposable pad 14 move along with it, causing one end of the limiting post 16 to insert into the groove 17. At the same time, due to the shape design of the limiting post 16, the limiting post 16 will be stuck in the groove 17. When the extension block 7 returns to its original position along with the clamping plate 8, the limiting post 16 will not return to its original position. At this time, the disposable pad 14 is no longer constrained and fixed, making it easy to remove the used disposable pad 14 and expose the unused disposable pad 14 for the next patient to use.

[0026] The sliding frame 3 is sealed and slidably connected within the fixed frame 2. An air inlet pipe 18, connected to the interior and equipped with a one-way valve, is fixedly installed on the top of the sliding frame 3. An air outlet pipe 19, also connected to the interior and equipped with a one-way valve, is fixedly installed on the bottom of the sliding frame 3. One end of the air outlet pipe 19 is connected to the air outlet frame 20 at the bottom of the clamping plate 8. Several air outlet holes are opened on one side of the air outlet frame 20. A filter screen 21 is fixedly installed inside the air outlet holes of the air outlet frame 20. A trumpet-shaped guide column 22 is fixedly installed on one side of the filter screen 21; the guide column 22 is hollow.

[0027] During operation, when the patient finishes the examination and leaves the examination bed 1, the extension block 7, as it slides into the sliding frame 3, compresses the internal gas, causing the gas inside the sliding frame 3 to enter the air outlet of the air outlet frame 20 through the air outlet pipe 19 and be ejected. The gas inside the sliding frame 3 is replenished through the air inlet pipe 18.

[0028] When the gas is ejected, it passes through the filter 21. Some of the gas is directly ejected through the hollow design of the guide column 22, while the other part is guided to the surrounding area through the trumpet-shaped guide column 22, thereby expanding the blowing area. This cleaning of the area where the patient's head lies on the examination bed 1 reduces the residue of impurities (referring to hair and dandruff), preventing long or thick hair from forming high-density shadows or stripe artifacts in the image, which would affect the accuracy of the examination. Timely cleaning also reduces the risk of cross-infection.

[0029] Working principle: When a patient lies on the examination bed 1 for testing, the insertion rod 5 is pulled out of the through slot 6, facilitating the sliding adjustment frame 3 within the fixed frame 2. This allows the sliding frame 3, carrying the extension block 7, clamping plate 8, and pad 9, to move to the appropriate position and stop. The insertion rod 5 is then reinserted into the slot 4 of the sliding frame 3 through the appropriate through slot 6 for fixation, ensuring the clamping plate 8 and pad 9 can adapt to different patient head positions. Pulling the extension block 7 within the sliding frame 3 moves the extension block 7, carrying the curved clamping plate 8 and pad 9, towards the patient's head. During this movement, the sliding frame 3 continuously contacts the positioning ball 12 with the positioning groove 10, causing the positioning ball 12 to repeatedly enter and exit the positioning groove 10. When the extension block 7 reaches the appropriate position and stops, the positioning ball 12 enters the positioning groove 10 to assist in fixing the extension block 7.

[0030] Several disposable pads 14 are laid on the clamping plate 8, with one side of the disposable pad 14 contacting the gasket 9, and both ends passing through two rectangular grooves 13 and contacting the back of the clamping plate 8. At this time, the connecting rod 23, along with two limiting posts 16, inserts parts of the disposable pads 14 into the limiting grooves 15 for fixation, thereby fixing the disposable pads 14 on the clamping plate 8. After the previous patient finishes using the device, as the extension block 7 moves the clamping plate 8 towards the sliding frame 3, the limiting posts 16 and other components such as the disposable pads 14 move along with them, causing one end of the limiting post 16 to insert into the groove 17. Due to the shape design of the limiting post 16, it will be stuck in the groove 17. When the extension block 7 returns to its original position with the clamping plate 8, the limiting post 16 will not return to its original position. At this time, the disposable pads 14 are no longer constrained and fixed, making it convenient to remove the used disposable pads 14 and expose the unused disposable pads 14 for the next patient to use.

[0031] When the patient finishes the examination and leaves the examination bed 1, the extension block 7, as it slides into the sliding frame 3, compresses the internal gas, causing the gas inside the sliding frame 3 to enter the air outlet of the air outlet frame 20 through the air outlet pipe 19 and be ejected. The gas inside the sliding frame 3 is replenished through the air inlet pipe 18. When the gas is ejected, it passes through the filter screen 21, and some of the gas is directly ejected through the hollow design of the guide column 22, while the other part of the gas is guided to the surrounding area through the trumpet-shaped guide column 22, thereby expanding the blowing area and cleaning the area where the patient's head is lying on the examination bed 1.
