In hospitals, we sometimes see medical staff pushing a large machine into the ward to examine patients. There will also be a sign of "ionizing radiation" on the machine. People often ask: "What is this big machine used for?" "The medical staff replied: "This is for taking X-rays in the ward." At this time, the patients will lament the advancement of technology, but some people will think that this is a mobile radioactive source and immediately hide away, not daring to Close; some patients may find it too troublesome to go to the radiology department for examination. Since we have this equipment, it would be great to have the doctor come to the bedside to take X-rays.
So what is a bedside X-ray camera? What are its uses? What are the pros and cons? Today, let’s talk to you about mobile X-ray machines.
1. What is a mobile X-ray machine?
With the increasing development of science and medical technology, X-ray photography equipment in hospitals is constantly being updated. In addition to X-ray equipment fixed in the radiology department room, there are also X-ray equipment that can be pushed around, that is, mobile It is an X-ray machine that medical staff can push to the side of the patient's bed for photography, so it is also called an X-ray bedside machine or simply a bedside machine.
2. What are the advantages of mobile X-ray machines, and how are they different from conventional X-ray photography?
As we all know, ordinary X-ray equipment is large in size and is placed in the radiology examination room. However, mobile X-ray machines are convenient and compact and can be pushed to the ward or operating room to examine patients, which can provide excellent diagnosis and treatment for patients. Great convenience.
3. Under what circumstances is a mobile X-ray machine needed?
Determine whether patient tubing is in correct position
Many patients have many tubes inserted into their bodies due to physical reasons. For example, gastric tube, PICC tube, etc., whether these tubes are in place or not needs bedside chest X-ray to confirm.
Understand common chest lesions in critically ill patients
Many patients have fractures due to chest trauma or are bedridden and unable to move. Doctors need to understand the chest conditions of these patients and need bedside chest X-rays to confirm.
Critically ill patients after surgery
The physical evaluation of some postoperative patients, such as ICU patients, liver transplant, kidney transplant, and lung transplant patients, requires bedside chest radiography to confirm.
Intraoperative positioning of foreign bodies or surgical instruments.
The positioning of foreign bodies or surgical instruments during surgery requires bedside chest radiography to determine.
4. Limitations of mobile X-ray machines
1. The technical parameters of mobile X-ray machines are lower than those of fixed equipment. Coupled with long-term movement and bumps, the photographic quality will be relatively poor. In other words, bedside photography is the next best option when there is no better way, and the image quality will obviously be greatly compromised;
2. There are also great limitations in the applicable examination parts. Not all examinations can be completed with the mobile X-ray machine. It is most commonly used for chest photography of patients, which is often called bedside chest X-ray;
3. X-ray examination has radiation risks. The fixed equipment rooms of the radiology department are all treated with radiation protection in accordance with the requirements of national standards. However, wards, operating rooms, etc. do not have such protective measures. Bedside X-ray photography may cause Patients, family members, and medical staff in close proximity generate unnecessary radiation;
Therefore, X-ray bedside examination can never replace conventional photography examination. It can be used as an auxiliary examination method in emergency situations to provide convenience for patient diagnosis and treatment. When it is necessary to use it to examine patients in the ward, nearby unrelated personnel should avoid it as much as possible to avoid unnecessary radiation. Moreover, the mobile X-ray machine does not produce radiation when it is moving or parked. X-rays are emitted only at the moment of exposure (less than 1 second); moreover, the radiation dose of a chest X-ray for the subject is, It is almost equal to the radiation received from nature in three days of normal life. Don’t be afraid when there are other patients in the ward having bedside X-rays taken. When taking pictures at the bedside, the safe area is 2 meters away!
Kind tips:
1. There will be no radiation when the bedside radiography equipment is moved or parked. Radiation is emitted only at the moment of filming (less than 1 second), so there is no need to be afraid of it;
2. Inpatients should follow the doctor's instructions. The doctor will decide whether to go to the fixed computer room or bedside for X-ray examination. If possible, try to go to the fixed computer room of the radiology department. Never think that going to the radiology department is too troublesome and ask the doctor to prescribe bedside X-ray examinations. This is not conducive to the diagnosis and treatment of your disease;
3. Don’t be afraid when there are other patients in the same room taking bedside X-rays in the ward. The national standard requires that "protective measures should be taken for subjects adjacent to beds (within 2m)". In other words, 2 meters away is considered a safe area! Let me tell you quietly, the radiation dose of a chest X-ray taken by a subject is almost equal to the radiation received from nature in three days of normal life. We are in an environment of ionizing radiation every day and receive trace amounts of ionizing radiation all the time. When someone takes a photo, you are 2 meters away. Do you think there is any need to worry?
