A contrast device for cerebral vascular disease in the elderly

Abstract

This invention discloses an angiography device for elderly patients with cerebrovascular diseases, including a base, a digital subtraction angiography (DSA) machine mounted on top of the base, a support platform on the upper surface of the base, a support plate on the upper surface of the support platform, and a support pad fixedly mounted on the upper surface of the support plate. This angiography device for elderly patients with cerebrovascular diseases uses a headrest mechanism to adjust the position of the fixed base relative to the support plate and the position of the support platform relative to the base according to the patient's head position when lying down. This ensures both a comfortable position for the patient and a suitable position for the head and the angiography machine's transmitting components. A sliding rod is pressed by sliding the limiting plate, causing the sliding rod to move the side clamps to hold the patient's head. Simultaneously, a flip-up mechanism after sliding up provides lateral support and limitation for the patient via rubber support rollers, helping to better stabilize the patient's head.

Description

Technical Field

[0001] This invention relates to the field of cerebral angiography technology, specifically to an angiography device for cerebrovascular diseases in the elderly. Background Technology

[0002] Cerebral angiography is a common neurological or neurosurgical examination, mainly used to examine the condition of cerebral blood vessels, such as stenosis, cerebral aneurysms, and arteriovenous malformations. Before the examination, fasting is required, and a catheter is inserted through the femoral artery to inject contrast agent. The patient then lies on the angiography machine for the examination. During the angiography, the patient needs to keep their head relatively still to reduce the impact of artifacts caused by head movement on the examination results. However, due to tension or pain, patients may experience slight tremors during the examination, requiring head fixation. For example, a head support device for cerebral angiography in neurology, application number CN202110052297.6, uses components such as a traction motor, a moving plate, and a clamping plate to fix the patient's head. However, when the patient places their head on a headrest, the position of the patient's head needs to be constantly adjusted to ensure that the patient's head is directly below the angiography machine's transmitting component, as different patients have different head sizes. This adjustment process requires the patient to follow the doctor's instructions to move their body, which is very difficult for some patients with limited mobility or impaired consciousness. During angiography, patients need to lie on the examination table. However, due to differences in patients' conditions and physical circumstances, as well as the design of the angiography device, patients need medical staff to assist them in lying down. For example, a cerebral artery angiography device with application number CN201911038405.3 can only be accessed by patients with the help of medical staff. This not only requires close cooperation from medical staff, but also requires lifting patients who are unable to move to transfer them over the table. This not only affects the patient's body, but also increases the risks associated with transferring them over the table. Summary of the Invention

[0003] The purpose of this invention is to provide an angiography device for cerebrovascular diseases in the elderly, so as to solve the problems mentioned in the background art, such as the poor fixation of the patient's head and the inconvenience of the patient climbing onto the examination table.

[0008] Preferably, one end of the first push switch protrudes from the inner surface of the fixed base, and the end of the first push switch protruding from the inner surface of the fixed base is in contact with the outer surface of the first contact plate. The side surface of the rotating plate is fixedly connected to one end of the output shaft of the rotary motor, and the rotating plate and the second contact plate are slidably connected. A spring is connected between the rotating plate and the second contact plate.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This application provides an angiography device for elderly patients with cerebrovascular diseases. The angiography device for elderly patients with cerebrovascular diseases reduces the patient's head discomfort and ensures that the patient's head is correctly positioned relative to the angiography machine's transmitting components through a headrest mechanism and a lateral support mechanism.

[0019] The following provides a detailed description of the angiography device for treating cerebrovascular diseases in the elderly. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0020] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] An angiography device for cerebrovascular diseases in the elderly includes: a base 1, a digital subtraction angiography machine 2 disposed above the base 1, a support platform 3 disposed on the upper surface of the base 1, a support plate 4 disposed on the upper surface of the support platform 3, and a support pad 5 fixedly disposed on the upper surface of the support plate 4. The headrest mechanism is located on the upper surface of one end of the support plate 4 and is used to adapt to the position of the patient's head. The headrest mechanism includes: a fixed seat 601 disposed at one end of the support plate 4, a side clamping plate 608 installed inside the side surface of the fixed seat 601, a sliding rod 609 fixedly disposed on the side surface of the side clamping plate 608, an adjusting motor 610 fixedly installed on the upper surface of one end of the support plate 4, a displacement rod 611 fixedly connected to the output shaft of the adjusting motor 610, and a positioning electric push rod 612 fixedly installed on the upper surface of the base 1. The headrest mechanism also includes: a first contact plate 602 installed on the inner surface of the fixed base 601, a first push switch 603 embedded in the side surface of the fixed base 601, a rotating plate 604 rotatably installed inside one end of the fixed base 601, a rotary motor 605 fixedly installed inside one end of the fixed base 601, a second contact plate 606 installed on one side surface of the rotating plate 604, and a second push switch 607 embedded in the side surface of the rotating plate 604. Lateral support mechanism, located on the side surface of the bearing plate 4, is used to provide lateral support to the patient and prevent movement. The lateral support mechanism includes: a limiting electric push rod 701 fixedly installed on the lower surface of the bearing plate 4, a limiting plate 702 fixedly installed at one end of the limiting electric push rod 701, a flap 703 rotatably installed inside the side surface of the limiting plate 702, and a rubber support roller 704 fixedly installed on the side surface of the flap 703. The outer surface of the limiting plate 702 is in contact with the outer surface of the bearing plate 4, and one end of the limiting plate 702 is located directly below the inclined surface of one end of the sliding rod 609. The support platform 3 is slidably connected to the base 1, and one end of the support platform 3 is fixedly connected to the positioning electric push rod 612. The support platform 3 is rotatably mounted to the bearing plate 4. The fixed seat 601 is slidably connected to the first contact plate 602, and a spring connects the first contact plate 602 to the fixed seat 601. The lower end of the first contact plate 602 has an arc-shaped design. The fixed seat 601 is threadedly connected to the displacement rod 611, and the fixed seat 601 is slidably connected to the bearing plate 4. The side clamping plate 608 is slidably connected to the fixed seat 601 via a sliding rod 609. The side clamping plate 608 has an arc-shaped design with its opening facing inwards towards the fixed seat 601, and the sliding rod 609 faces outwards towards the fixed seat 601. One end is designed as a right-angled trapezoid, and the sliding rod 609 is set at an angle downward. One end of the first push switch 603 protrudes from the inner surface of the fixed base 601, and the end of the first push switch 603 protruding from the inner surface of the fixed base 601 is in contact with the outer surface of the first contact plate 602. The side surface of the rotating plate 604 is fixedly connected to one end of the output shaft of the rotary motor 605, and the rotating plate 604 and the second contact plate 606 are slidably connected. A spring is connected between the rotating plate 604 and the second contact plate 606. The second contact plate 606 protrudes from the outer surface of the rotating plate 604, and the outer surface of the second contact plate 606 is in contact with the outer surface of one end of the second push switch 607. During the imaging process, the patient first lies on the support pad 5 on the support plate 4. At this time, the patient's head is in contact with the first contact plate 602. The first contact plate 602 is pressed against the fixed seat 601, which slides and presses against the first press switch 603. The first press switch 603 sends an electrical signal to the regulating motor 610. The regulating motor 610 starts and drives the displacement rod 611 to rotate. The displacement rod 611, through its threaded connection with the fixed seat 601, drives the fixed seat 601 to slide a distance away from the patient's head until the patient is completely lying down and no longer in contact with the first contact plate 602. At this time, the rotary motor 605 starts and drives the rotating plate 604 to rotate, so that the rotating plate 604 drives the second contact plate 606 to rotate to the patient's chin. At this point, the adjusting motor 610 continues to drive the fixed base 601 to move away from the patient's head via the displacement rod 611, causing the second contact plate 606 to move towards the patient's chin. When the second contact plate 606 contacts the patient's chin and is squeezed and slid to trigger the second press switch 607, the second press switch 607 sends an electrical signal to the adjusting motor 610 and the positioning electric push rod 612. At this point, the adjusting motor 610 stops working, while the positioning electric push rod 612 drives the support platform 3 to slide in the opposite direction relative to the base 1 by the total length of the sliding of the fixed base 601 driven by the adjusting motor 610, so that the patient's head is moved to directly below the transmitting component of the digital subtraction angiography machine 2. After the patient lies down, the electric limiter 701 is activated, causing the limiter plate 702 to slide upwards. The upward movement of the limiter plate 702 presses against the inclined surface of the sliding rod 609, allowing the sliding rod 609 to slide and clamp the patient's head via the side clamp 608. Simultaneously, after the limiter plate 702 has fully slid upwards, the flip plate 703 is flipped, causing the rubber support roller 704 to face the patient and provide support. Then, the electric limiter 701 causes the limiter plate 702 to slide downwards a short distance, causing the lower side surface of the flip plate 703 to adhere to the side surface of the support plate 4 and prevent it from flipping over. This ensures that the flip plate 703 can provide stable support to the patient via the rubber support roller 704. Example

[0022] Please see Figure 1-11 In this embodiment, an angiography device for cerebrovascular diseases in the elderly is provided, including: a base 1, a digital subtraction angiography machine 2 is provided above the base 1, a support platform 3 is provided on the upper surface of the base 1, a support plate 4 is provided on the upper surface of the support platform 3, and a support pad 5 is fixedly provided on the upper surface of the support plate 4. The headrest mechanism is located on the upper surface of one end of the support plate 4 and is used to adapt to the position of the patient's head. Lateral support mechanism, located on the side surface of the bearing plate 4, is used to provide lateral support to the patient and prevent movement. The imaging device is equipped with an adjustment auxiliary mechanism; The adjustment auxiliary mechanism includes: a lifting hydraulic rod 801 rotatably mounted on the upper surface of the support platform 3, and a connecting seat 802 rotatably mounted on the upper end of the lifting hydraulic rod 801; The connecting seat 802 is slidably connected to the bearing plate 4, and the support platform 3 is rotatably connected to the bearing plate 4. When it is inconvenient for the patient to lie on the support plate 4, the lifting hydraulic rod 801 is activated. The lifting hydraulic rod 801 drives the support plate 4 to rotate downward relative to the support platform 3 through the connecting seat 802, so as to change the height of one end of the support plate 4, allowing the patient to lie on the support plate 4 in a semi-reclining position. Then, the lifting hydraulic rod 801 drives the support plate 4 to rotate upward and reset through the connecting seat 802, so that the patient can undergo the angiography examination in a supine position.

When it is inconvenient for the patient to lie on the support plate 4, pull down the limiting pin 902 to disengage the slide plate 901 from the support plate 4. Then, push the patient to the side of the support plate 4 where the slide plate 901 is installed via the wheelchair. Then, lift the patient and the sheet together. At this time, pull the slide plate 901 to move it directly under the lifted patient. Then, gently place the patient on the slide plate 901. Slide the slide plate 901 back to its original position to complete the purpose of the patient climbing onto the support plate 4. After the slide plate 901 is reset, the limiting pin 902, under the pull of the spring, resumes its engagement with the slide plate 901 to limit the slide plate 901.
