Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a medical imaging examination bed. Background Art

[0002] Medical imaging refers to the technology and process of obtaining images of internal tissues of the human body or a part of the human body in a non-invasive manner for medical treatment or medical research. It includes the following two relatively independent research directions: medical imaging system and medical image processing. The former refers to the process of image formation, including the study of imaging mechanism, imaging equipment, imaging system analysis and other issues; the latter refers to further processing of the acquired images, the purpose of which is to restore the original unclear image, to highlight certain feature information in the image, or to classify the image pattern, etc. X-rays are used to examine the human body and diagnose diseases, forming a new discipline of radiological diagnosis and laying the foundation for medical imaging. To this day, radiological diagnosis is still the main content of medical imaging and is widely used.

[0003] Nowadays, hospitals are equipped with imaging detection instruments to perform imaging detection on patients, and imaging examination beds are important tools to assist patients in performing imaging detection. During the use of existing imaging examination beds, the height of the imaging examination beds is certain and the structure is fixed. Therefore, it cannot meet the needs of imaging detection instruments of various specifications to perform imaging detection operations on patients, which increases the use limitations of the imaging examination beds. Summary of the invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provides a medical imaging examination bed to adjust the height of the imaging examination bed.

[0005] To achieve the above object, the present invention adopts the following technical solution: a medical imaging examination bed, comprising a support base and a support body fixed on the support base, wherein the support body is vertically slidably matched with a bed body;

[0006] A plurality of drive groups are installed on the support seat, and the drive group includes a drive member and a main bevel gear fixed on the output shaft of the drive member, the main bevel gear is meshed with a slave bevel gear, a rotating shaft is fixed to the slave bevel gear, the rotating shaft is threadedly connected to the bed body, and the rotating shaft is rotatably connected to the support seat;

[0007] One side of the bed body is horizontally slidably connected with a headrest, and the other side of the bed body is horizontally slidably connected with a plurality of extension parts, which are evenly distributed along the width direction of the bed body.

[0008] The principle and effect of the above technical solution: (1) In this solution, when the height of the bed needs to be adjusted, the driving member drives the main bevel gear to rotate, the main bevel gear drives the slave bevel gear to rotate, and the slave bevel gear drives the rotating shaft to rotate. Since the rotating shaft and the bed are threadedly connected, and the bed is limited by the support body, the bed can move upward or downward stably, thereby achieving the purpose of height adjustment to adapt to different image detection instruments.

[0009] (2) In this solution, the headrest can be slid horizontally to accommodate the heights of different people. Of course, the extension part can also be slid horizontally to support the patient's legs to accommodate patients of different heights. In this way, the purpose of extending the bed can be achieved.

[0010] In a preferred embodiment of the present invention, guardrails are fixed on both sides of the bed.

[0011] Beneficial effect: The guardrail is used to protect the patient on the bed.

[0012] In a preferred embodiment of the present invention, a guide shaft vertically slidably connected to the guardrail is fixed on the support body.

[0013] Beneficial effect: During the rising or falling of the bed, the guardrail can always protect the patient. If the falling distance is too large (the bed moves into the support body), the guardrail can extend into the support body to protect the patient through the support body.

[0014] In a preferred embodiment of the present invention, a drive shaft is rotatably connected to the bed body, and threads with opposite rotation directions are arranged on both sides of the drive shaft. One end of the drive shaft is threadedly connected to a drive block, and the drive block is horizontally slidably matched with the headrest. The other end of the drive shaft is connected to a connecting plate, and a plurality of extensions are fixed on the connecting plate. A power member is arranged on the bed body, and a main gear is fixed to the output shaft of the power member, and the main gear is meshed with a slave gear coaxially fixed with the drive shaft.

[0015] Beneficial effect: In this solution, the power part drives the main gear to rotate, the main gear drives the slave gear to rotate, and the slave gear drives the drive shaft to rotate. Since the threads at both ends of the drive shaft rotate in opposite directions, the drive shaft synchronously drives the drive block and the connecting plate to move toward both sides of the bed, and then synchronously drives the headrest and the extension part to move toward both sides of the bed, thereby reducing the adjustment time.

[0016] In a preferred embodiment of the present invention, a slide groove is formed on the driving block, a slider is fixed on the headrest, and the headrest is horizontally slidably matched with the driving block through the slide groove and the slider.

[0017] Beneficial effect: In this solution, if the headrest is not adjusted to an appropriate position, the position of the headrest can be slid autonomously to make the patient's head more comfortable.

[0018] In a preferred embodiment of the present invention, guide blocks are fixed on both sides of the extension portion, and guide grooves are provided on the bed body to horizontally slide with the guide blocks.

[0019] Beneficial effect: The extension part is guided by the guide groove and the guide block during sliding, and the extension part is supported by the guide block in cooperation with the bed body, so as to improve the stability of the extension part.

[0020] In another preferred embodiment of the present invention, rolling wheels are arranged on the bed.

[0021] Beneficial effect: When the bed body moves upward or downward to adjust its height, the friction resistance between the bed body and the support body is reduced by the roller, which is conducive to the upward or downward movement of the bed body.

[0022] In another preferred embodiment of the present invention, a support block vertically slidably connected to the support body is fixed on the bed.

[0023] Beneficial effect: When the bed body moves upward or downward, the support blocks guide the bed body, thereby improving the stability of the bed body moving upward or downward.

[0024] In another preferred embodiment of the present invention, a guide rail is provided at the lower portion of the support seat.

[0025] Beneficial effects: The medical imaging examination bed is moved by the guide rail, so that the medical imaging examination bed can be moved to the bottom of the imaging detection instrument, which is convenient for medical staff to operate.

[0026] In another preferred embodiment of the present invention, a cavity is formed between the bed body and the support seat, the cavity is communicated with the support seat, and the bottom of the support seat is communicated with an air hole.

[0027] Beneficial effects: In this solution, when the bed moves upward, gas is sucked in through the pores and the cavity, and when the bed moves downward, gas is discharged through the pores and the cavity. The discharged gas blows out the dust under the support seat to facilitate cleaning by medical staff.
