Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a device that effectively reduces CT neck examination artifacts. Background Art

[0002] At present, the bedside support for CT examination is basically a single-function support, with a horizontal bottom, vertical side walls, and a fully open top. The connection position of the head support connecting arm and the bracket is fixed, and it is only designed and used for head CT scanning. Many emergency patients with stroke and craniocerebral trauma often have involuntary head movements due to intracranial lesions, which affects the scanning results, causing the CT scanning artifacts to be too large and requiring multiple repeated scans, which will expose the patient to unnecessary ionizing radiation. In addition, large artifacts can also lead to inaccurate diagnosis, which in turn affects the patient's treatment.

[0003] 1. Existing devices for reducing CT neck examination artifacts usually use components such as head supports and straps to limit and fix the patient's head. The wearing process is cumbersome and the fixation effect on the patient's head is poor;

[0004] 2. Existing devices for reducing CT neck examination artifacts are not suitable for patients with hunchbacks and require assistance from other devices, which is inconvenient to use. Utility Model Content

[0005] The utility model aims to provide a device that effectively reduces CT neck examination artifacts, which has the characteristics of being convenient for fixing the patient's neck and being applicable to hunchback patients.

[0007] The upper end surface of the moving box is fixedly connected with a support block, and the upper end surface of the moving box is fixedly connected with two vertical plates distributed front and back and located on the left side of the support block, and a limited position fixing component is arranged between the two vertical plates.

[0008] In order to limit and fix the patient's neck, as a preferred device of the utility model for effectively reducing CT neck examination artifacts, the limit and fixation component includes a supporting airbag fixedly connected to the upper end face of the movable box and located between two vertical plates, one side wall opposite to the two vertical plates is fixedly connected to a fixed airbag located above the supporting airbag, and one side wall opposite to the two vertical plates is installed with an inflation pump connected to the fixed airbag.

[0009] In order to drive the support plate to move, as a preferred device for effectively reducing CT neck examination artifacts of the utility model, the front and rear end surfaces of the support plate are fixedly connected with connecting blocks, the interior of the moving box is rotatably connected with a screw threadedly connected to one of the connecting blocks, and the interior of the moving box is fixedly connected with a sliding rod slidably connected to the other connecting block.

[0010] In order to facilitate the pressure sensor to send signals to the inflation pump, as a preferred device of the present invention for effectively reducing CT neck examination artifacts, pressure sensors are installed on the opposite side walls of the two fixed airbags, and the pressure sensors are electrically connected to the inflation pump.

[0011] In order to provide power for the movement of the moving box, as a preferred device of the utility model for effectively reducing CT neck examination artifacts, a telescopic cylinder is installed on the lower end surface of the bed, and the output end of the telescopic cylinder is fixedly connected to the moving box.

[0012] In order to provide power for the rotation of the screw rod, as a preferred device of the utility model for effectively reducing CT neck examination artifacts, a motor is installed inside the moving box, and the output end of the motor is fixedly connected to the screw rod.

[0013] In order to increase the comfort of hunchback patients, as a preferred device for effectively reducing CT neck examination artifacts of the utility model, one side of the support plate is an arc-shaped structure.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The air pump inflates the fixed airbag, and the patient's neck is fixed by the expansion of the fixed airbag. The pressure between the fixed airbag and the patient's neck is detected by the pressure sensor. When the pressure between the two fixed airbags and the patient's neck reaches the set value, the two air pumps stop inflating, thereby conveniently and quickly fixing the patient's neck, thereby effectively reducing artifacts in CT neck examinations;

[0016] When performing a CT neck examination on a hunchback patient, the telescopic cylinder pushes the moving box to move until the lower end of the opening of the through hole is flush with the bed body, and then the screw rod cooperates with the connecting block to drive the support plate to move, so that the support plate is moved out of the moving box, and a slope is formed between the moving box and the bed body through the support plate. The back of the hunchback patient is supported by the slope, so that the hunchback patient can lie flat on the bed body, and then the neck of the hunchback patient is moved between the two vertical plates, and the neck of the hunchback patient is limited and fixed by a fixed airbag, so that a CT neck examination can be performed on the hunchback patient.
