Description

A pushing device for cerebral perfusion CT scanning

technical field

The utility model belongs to the field of medical equipment, in particular to a pushing device for cerebral perfusion CT scanning.

Background technique

In recent years, with the continuous shortening of CT scanning time, CT cerebral perfusion imaging research for the purpose of observing brain tissue blood perfusion has become a hot spot. The concept of CT perfusion imaging was first proposed by MILES et al. in 1991. The theoretical basis comes from the data processing technology of radionuclide imaging brain perfusion images. CT brain perfusion imaging can accurately reflect the degree of tissue vascularization and blood perfusion, but it needs to emphasize contrast agent bolus injection and high temporal resolution.

When performing CT cerebral perfusion examination, the patient's position is supine, and the head needs to be as close to the patient's chest as possible, and the head is completely exposed for scanning examination. However, the patient cannot complete the above-mentioned actions independently during the usual examination process, and for an older patient, lying with the head supine on the chest is likely to cause hypoxia.

Contents of the invention

Aiming at the defects and deficiencies in the prior art, the purpose of this utility model is to provide a pushing device for cerebral perfusion CT scanning, which can not only assist the doctor to prop up the patient's head as close to the chest as possible, but also The oxygen inhalation interface set on the top can facilitate the operation of the patient and avoid the damage caused by the patient's hypoxia during the examination process.

In order to achieve the above-mentioned purpose, the technical scheme that the utility model takes is;

A pushing device for brain perfusion CT scanning, in which an extension plate is arranged at the end of the CT bed close to the CT scanner, a sliding push member is arranged on the extension plate, and the human body is moved by sliding the push member along the length direction of the extension plate. The back of the head is sliding and pushing, so that the person's head moves close to the chest.

detailed description

The utility model discloses a pushing device for brain perfusion CT scanning. An extension plate 2 is arranged at the end of a CT bed 1 close to the CT scanner, and a sliding pushing member is arranged on the extending plate 2. The sliding of the length direction of the board 2 slides and pushes the back of the human head, so that the human head moves close to the human chest, fully exposing the parts to be inspected, so as to perform accurate scanning, save inspection time, and reduce the need for patients to perform autonomous inspections. The pain of lifting position control is very good to assist the medical staff to perform a quick scan and check, and provide fast and accurate test results for later diagnosis and treatment.

A scheme of a sliding push member includes a position-adjusting support rod 5, a slider 4, and a backbrain support 6. The extension plate 2 is provided with a first chute 21 along the length direction, and one end of the position-adjusting support rod 5 is fixed to the slider 4. Connect, the other end of the position-adjusting support rod 5 is fixedly connected with the backbrain support member 6, the slide block 4 slides back and forth along the first chute 21 to drive the adjustment of the position-adjusting support rod 5 to the adjustment of the support position of the hindbrain support member 6, and the position-adjusting support rod 5. Driven by the slider 4, the position of the backbrain support 6 along the horizontal and height directions can be changed, which not only meets the position requirement that the human head needs to be as close to the chest as possible in the brain perfusion CT scan, but also the sliding control The position can be finely adjusted by the method, and the medical staff can make independent adjustments according to the examination needs of different patients.

A scheme for adjusting the position of the support rod 5 to realize height and horizontal position adjustment. The position-adjusting support rod 5 is a "Z"-shaped rod body with two bending points. The first bending point 52 of the position-adjusting support rod 5 It is a rotatable inflection point, and the second inflection point 54 is a fixed inflection point; the rod body of the position-adjusting support rod 5 that is only connected to the first inflection point 52 is fixedly connected with the slider 4 along the length direction of the extension plate 2. The rod body end that only connects the second inflection point 54 of the position support rod 5 is fixedly connected with the backbrain support member 6, and the best position adjustment support rod 5 only connects the rod body of the first inflection point 52 along the length of the extension plate 2 The direction passes through the slider 4 and is fixedly connected with the slider 4. A handle 51 is installed on the exposed end. When adjusting the position, the sliding position of the slider 4 can be adjusted by holding the handle 51. When the chest moves close to the chest, pull the handle 51 to make the slider 4 slide away from the CT bed, and the position adjustment support rod 5 rotates at the first bending point 52, so that the two bending points on the position adjustment support rod 5 are connected. The rod body between the inflection points is nearly upright to realize the change in the height direction. At this time, the rod body on the second inflection point 54 pushes the back of the brain support 6 along the direction close to the CT bed to move in the horizontal direction, thereby realizing the head approaching Chest position adjustment.

In order to fix the moving position of the position-adjusting support rod 5 and prevent it from shaking left and right, a spacer frame 3 is also arranged on the extension plate 2. The spacer frame 3 is a frame in the shape of a "door". A vertical frame is fixedly connected with the extension plate 2 along the vertical direction, and the rod body connected with the first bending point 52 and the second bending point 54 of the position-adjusting support rod 5 is sleeved on the transverse frame 3 through the connecting ring 53 On the frame, it can not only prevent the shaking of the position-adjusting support rod 5, but also the structure with a fulcrum satisfies the principle of leverage, so that the position-adjusting support rod 5 is more labor-saving when adjusting the back of the head support.

In order to control whether the slider 4 slides, a second chute 22 is provided along the side of the extension plate 2, the second chute 22 communicates with the first chute 21 and has the same length, and a tightening bolt is arranged in the second chute 22 41. The position of the slider 4 is fixed by tightening the tightening action of the bolt 41.

In order to increase the comfort of the patient, the backbrain supporting member 6 is a hard sheet conforming to the shape of the back of the human body, and a cushion is arranged in the hard sheet to make the supporting process more comfortable.

Due to the special position of the brain perfusion CT examination, the head should be as close to the chest as possible. Some patients, especially older patients, are prone to hypoxia symptoms during the examination. The oxygen inhalation connector 71 can be connected to the oxygen pipe conveniently and quickly, so as to realize immediate and rapid oxygen supply to the patient.
