Description

Auxiliary movement adjusting system and method for CT lung detection of children

Technical Field

The invention relates to the field of medical instruments, in particular to a child CT lung detection auxiliary movement adjusting system and method.

Background

Medical instruments refer to instruments, devices, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly in the human body. Among them, CT is an electronic computed tomography, which uses precisely collimated X-ray beams, gamma rays, ultrasonic waves, etc. to perform cross-sectional scanning one by one around a certain part of a human body together with a detector having a very high sensitivity, has the characteristics of fast scanning time, clear images, etc., and can be used for the examination of various diseases.

During CT detection, a detected person needs to lie on a CT bed and control the body to keep a stationary state, so that the CT image is prevented from being inaccurate due to movement during detection; when children receive lung CT detection, because the existing CT bed is usually a single bed board, but the children do not have good self-control capability, the children are difficult to keep in a stationary state when lying on the single bed board and are easy to drop from the CT bed; in addition, since children are in the childhood, the radiation impact of CT detection is also higher for children than for adults; the existing CT bed does not have a structure for fixing the limbs of the children, does not have a structure for protecting the radiation of the children, and cannot meet the use requirement.

Therefore, those skilled in the relevant art also make some improvements to the process of performing CT examination on children, such as a CT child examining table disclosed in chinese patent with publication number CN204484150U for more accurate comparison; when the novel bed plate is used, after children are placed on the bed plate, the pawl is pulled out, the sliding plate is pushed inwards, the sliding plate can clamp the trunk of the children, therefore, the effect of preventing the children from moving or shaking the body in the CT (computed tomography) inspection process can be achieved, and the children can be prevented from falling off the bed plate.

An auxiliary device for CT scanning of children is also disclosed in Chinese patent with publication number CN 202776346U; it is when using, places the service creeper on CT inspection bed, and the children of receiving examination lie on the service creeper, and rethread nylon fastener makes elastic fixation area can fix in order to avoid its activity and drop to the position of receiving examination children, and the lead skin that elastic fixation area surface set up can play the effect of carrying out radiation protection to children.

However, in the practical use process of the technical solution disclosed in the CT child examining table, on one hand, the problem of radiation protection of children during examination cannot be solved; on the other hand, a structure for preventing the head of the child from moving is not arranged, and when the head of the child uses the CT to detect the lung, the head of the child easily drives the chest to move, so that the detection effect of the CT on the lung of the child is influenced; moreover, the structure arranged on the bed board is only suitable for children, when the bed board is used by adults, the structure can influence the adults to cause the adults not to lie down, so that the applicability of the CT equipment is reduced, the CT equipment specially used for children and related accessories are required to be added in hospitals except for common CT equipment, and the cost of the hospitals is improved.

Furthermore, the technical scheme disclosed by the auxiliary device for the child CT scanning does not have a structure for preventing the head of the child from moving on one hand in the actual use process; on the other hand, before the child performs the detection, the lying plate needs to be moved to the CT bed manually, and when the adult uses the CT machine, the lying plate needs to be moved from the CT bed, and the process of moving the lying plate increases the working strength of the medical staff.

Thus, in view of the above statements, the prior art CT examination of children still leaves room for optimization.

Detailed Description

Embodiments of the invention will be described in detail below with reference to the accompanying fig. 1-9, but the invention can be implemented in many different ways, which are defined and covered by the claims.

The embodiment of the application discloses a child CT lung detection auxiliary movement adjusting system and an adjusting method, and the child CT lung detection auxiliary movement adjusting system and the adjusting method are mainly applied to the process of scanning and detecting the lung of a child by adopting CT equipment; the arm and the waist and abdomen part of the child can be protected from radiation under the condition of limiting and fixing the arm and the waist and abdomen part of the child, so that the limiting and fixing and radiation protection effects on the detected child are improved; especially, after the children finish CT scanning, the structure for protecting arms, waists and abdomens and limiting the arms and the waists and the abdomens can be adjusted and moved to the lower side of the CT fixed bed, so that the universality of the CT bed is improved.

The first embodiment is as follows:

referring to fig. 1 and 2, the auxiliary movement adjusting system for children CT lung detection comprises a CT fixed bed 1, a CT moving bed 2 and a scanning device 3, wherein a head stopper 4 driven by the CT moving bed 2 and moving towards the scanning device 3 is arranged at one end of the CT moving bed 2 close to the scanning device 3, and the head stopper 4 can support the head of a child and protect the head of the child from radiation, and can remove relevant parts when an adult uses the auxiliary movement adjusting system, so that the use of the CT moving bed 2 by the adult is not affected.

An arm limiter 5 for fixing the arms of the child is arranged on one side, close to the head limiter 4, of the upper end of the CT moving bed 2, a waist limiter 6 for fixing the waist of the child is arranged on the upper end, located on the right side of the arm limiter 5, of the CT moving bed 2, and the waist limiter 6 is connected with the arm limiter 5 through a telescopic rod 7 for telescopic adjustment, so that the positions of the telescopic rod 7, the arm limiter 5 and the waist limiter 6 can be adjusted according to the body size of the child, and the applicability of the invention is improved.
