Description

Special vehicle for MRI room

technical field

The utility model relates to a special vehicle for nuclear magnetic resonance chambers.

Background technique

Nuclear magnetic resonance, also known as magnetic resonance imaging, uses the characteristics of nuclear spin motion to place the human body in a special external magnetic field, and excites the hydrogen nuclei in the human body through radio frequency pulses, causing hydrogen nuclear resonance and absorbing energy. After stopping the radio frequency pulse Finally, the hydrogen nucleus emits a radio signal at a specific frequency, and releases the absorbed energy, which is collected by an external receiver and processed by an electronic computer to obtain an image. In the field of modern medicine, nuclear magnetic resonance examination has become one of routine examinations, and more and more patients need to undergo nuclear magnetic resonance examination. Due to the strong magnetic field in the nuclear magnetic resonance room, various equipment containing metal iron parts, including ordinary medical transfer flat cars, stretcher cars, surgical carts, rings on patients, glasses, underwear metal buckles, bone metal stents, vascular stents and other items are strictly prohibited When entering the MRI room, critically ill patients must be carried or carried in and out by the medical staff or their family members when entering and exiting the MRI room for examination. The labor intensity increases, which brings great inconvenience to medical examination.

Utility model content

The purpose of the utility model is to provide a special cart for the nuclear magnetic resonance room, especially a new type of trolley that can push the patient into the nuclear magnetic resonance room and transfer the patient to the examination bed of the nuclear magnetic resonance room without moving.

The purpose of this utility model is achieved by adopting the following technical solutions: the special vehicle for nuclear magnetic resonance room includes a cart, a stretcher bed, and a lifting mechanism, and the stretcher bed is placed on the cart. There are multiple stainless steel beams on the front of the stretcher bed, and multiple sets of horizontal and horizontal sliding load-bearing stainless steel bearings and horizontal orientation stainless steel bearings are installed on the multiple beams; there is a PVC plastic bed board that can move laterally above the stretcher bed, and there is a pusher on the trolley. Lifting mechanism for car lifting.

As a preferred technical solution of the present utility model, the lifting mechanism includes a retractable stainless steel lifting handle, a stainless steel transmission rod, a bronze worm wheel, a stainless steel worm, a stainless steel lifting gear and a stainless steel lifting rack, and the lifting handle is connected with the worm and the worm gear. , the worm gear is connected with the lifting gear at both ends of the transmission rod through the transmission rod, and the lifting gear meshes with the lifting racks arranged on both sides of the cart. Connected by the stainless steel transmission rod, the lifting rack is arranged in the four supporting feet of the trolley.

Since the special car for the nuclear magnetic resonance room of the utility model does not use iron parts, the stainless steel parts, the bronze worm wheel and the PVC plastic bed board can all enter the nuclear magnetic resonance room without being magnetized by the huge indoor magnetic field and then disturbing the nuclear magnetic resonance room. magnetic field and working environment, so the medical staff can push the patient into the MRI room; the bronze worm wheel is tough and wear-resistant, which reduces the wear rate of the special car for the MRI room; The trolley can be adjusted to the same height as the MRI examination table, and the patient can be translated onto the MRI examination table. During the whole process, the medical personnel do not need to lift the patient, which reduces the pain of the patient and the labor intensity of the medical personnel.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the nuclear magnetic resonance room special vehicle of the present utility model is further described:

Fig. 1 is a structural representation of the utility model;

Fig. 2 is a structural schematic diagram of the utility model lifting mechanism;

Figure 2-1 is a partial top view of the lifting mechanism in Figure 2;

Detailed ways

As shown in the figure, the utility model includes a cart 1, a stretcher bed 2, and a lifting mechanism 3, and the stretcher bed 2 is placed on the cart 1. The front of the stretcher bed 2 is provided with a plurality of crossbeams 22, and the plurality of crossbeams 22 are equipped with multiple groups of horizontal and lateral sliding load-bearing bearings 24 and lateral azimuth bearings 25; A lifting mechanism 3 for lifting and lowering the trolley is provided.

The front of the stretcher bed 2 is provided with five crossbeams 22, and a plurality of load-bearing bearings 27 are arranged on the top of each crossbeam 22. The sides of the three crossbeams 22 in the middle are equipped with bearing sliding grooves 23, and the horizontal and transverse sliding load-bearing bearings 24 are arranged on the sliding surface. In the groove 23, the load-bearing direction of the bearing is upward; the crossbeams 22 at both ends are provided with lateral azimuth bearings 25 to control the moving direction, and the lateral azimuth bearings 25 are two synchronously moving sliding bearings, which are respectively arranged on both sides of each crossbeam 22. The front of the cot 2 is also provided with a traversing positioning switch 26 .

The crossbeam 22 on the front of the stretcher bed 2 and the multiple groups of horizontal sliding load-bearing bearings 24 and lateral azimuth bearings 25 arranged on the crossbeam 22 can make the bed board move laterally on the stretcher bed and ensure that it will not deviate from the direction.

In actual operation, the patient who needs to be examined by nuclear magnetic resonance is pushed into the nuclear magnetic resonance room with the special vehicle of the utility model, and then the bed board on the stretcher bed and the patient are moved laterally to the nuclear magnetic resonance bed. The patient is moved back to the dedicated vehicle and rolled out of the MRI room. In this way, the patient does not need to be lifted back and forth, which reduces the pain of the patient and also reduces the labor intensity of the medical staff.
