Abstract

The invention provides an adjustable CT inspection protective cover for infants, which has a backboard for infants to lie on. The chest lead plate and the abdominal lead plate of the inner layer of the board slide along the length direction of the backboard in the first slideway respectively; In the second slideway parallel to the first slideway, the arched chest shield and the arched abdomen shield are slid in the second slideway with their two ends respectively. When in use, by flexibly adjusting the positions of the chest shield, abdomen shield and corresponding lead plates, CT examinations can be selectively performed on the head, chest or abdomen of infants.

Description

Adjustable protective cover for CT examination of infants and young children

technical field

The invention relates to a head and body radiation protection device for CT scanning of infants.

Background technique

"Newborn, Infant CT Scan Body Radiation Shield" - Zheng Zhigang, publication number is CN101732067A, discloses a kind of radiation protection device, its composition is to have bracket, lead rubber, lead door curtain, bracket fixing pin, bracket bottom The fixed pin can be fixedly connected with the CT scanning bed, the lead rubber is divided into blocks, and there are zippers or other adhesive materials combined with each other, which can be disassembled arbitrarily. The use of the bottom frame is still not convenient and fast enough, which affects the scanning speed, and the design of the head frame is not perfect.

"A CT Protection Device" - Liu Guangzhi, the publication number is CN203153776U, which discloses a CT protection device. It is equipped with four arched lead surface sliding chambers above the bottom plate that can slide smoothly on the bottom plate; the lead surface sliding chambers at both ends have the same shape, and the inner diameter is larger than the outer diameter of the lead surface sliding chamber in the middle; The inner diameter of one of the two lead surface sliding bins in the middle is larger than the other outer diameter; handles are provided on the outsides of the four lead surface sliding bins. Adjust the positions of the four lead surface sliding bins according to the needs. The disadvantage is that there is no protective device in the bottom plate, and there is no head bracket, so 360-degree all-round protection cannot be realized.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, the present invention provides an adjustable CT inspection protective cover for infants, which includes a backboard 10, a chest template 11 in the backboard 10, an abdominal template 12, and a backboard 10. The chest protective cover 21 on the top and the head support 23 on the abdominal protective cover 22, the backboard 10, wherein:

The backboard 10 can be used for infants to lie down, and the inner layer of the backboard 10 is provided with a first slideway 13 corresponding to the position of the infant's chest to the position of the legs, and the chest lead plate 11 arranged on the inner layer of the backboard 10 and the abdomen The lead plates 12 slide along the length direction of the backboard 10 in the first slideway 13;

Both sides of described backboard 10 are also all corresponding to infant's chest position to leg position and are provided with the second slideway 14 that is parallel with described first slideway 13, are arched chest protective cover 21 and are arched. The abdominal shield 22 is respectively slidably arranged in the second slideway 14 with its two ends, and the sum of the lengths of the chest shield 21 and the abdomen shield 22 is less than the length of the second slideway 14, so that the The chest shield 21 and the abdomen shield 22 can slide along the length direction of the backboard 10 respectively; The length is equal to the length of the abdomen shield 22;

As shown in Figures 5 and 6, the head rest 23 includes a lead glass base plate 24 and a transparent C-shaped lead glass cover plate 25, the lead glass base plate 24 is placed flat above the back plate 10, the One end of the lead glass cover plate 25 is hinged with one end of the lead glass bottom plate 24 with a hinge 26, and the other end can be engaged with the other end of the lead glass bottom plate 24; There is a flashboard 26 that can be connected with the chest protection equipment, so that the headrest 23 can be flexibly disassembled.

As shown in Figure 1, when checking the head of an infant, the head rest 23 is removed, the chest shield 21 and the chest lead plate 11 all stay at the position corresponding to the chest of the infant, and the abdomen shield Cover 22 and abdomen lead plate 12 all rest on the position corresponding to infant's abdomen, and at this moment, described chest shield 21 and the adjacent side of described abdomen shield 22 join with draw-in groove, are convenient to realize that two shields are paired. The seamless connection when closing to ensure that no radiation rays pass through the seams; in this way, head CT examination can be performed, and 360-degree radiation protection of the chest and abdomen can be realized.

As shown in Figure 2, when checking the infant's chest, the head rest 23 is plugged in, and after the infant's head falls on the lead glass bottom plate 24, the lead glass cover plate 25 is closed, and the Using the transparent lead glass cover plate 25, while reducing the sense of oppression, it is more convenient to observe the breathing and facial conditions of the child, so as to prevent sudden discomfort in the child during the scanning process, which is conducive to timely processing of emergency situations; The chest protective cover 21 and the chest lead plate 11 are moved to the junction corresponding to the chest and abdomen of the infant, and the abdomen protective cover 22 and the abdominal lead plate 12 are also moved to the foot side of the infant correspondingly, and keep the draw-in grooves connected, so that Chest CT examination can be performed by exposing the child's chest and protecting the abdomen and head.

As shown in Figure 3, when checking the abdomen of infants, the head support 23 is plugged in, and after the head of the infant falls on the lead glass bottom plate 24, the lead glass cover plate 25 is closed and passed Transparent lead glass cover plate 25 can observe infant's expression at any time; Described chest protective cover 21 and chest stereotyped plate 11 all stay in the position corresponding to infant's chest, described abdomen shield 22 and abdomen stereotyped plate 12 are moved To the position corresponding to the infant's feet, so that the abdomen of the infant is exposed, while the chest and head are protected, and the CT examination of the abdomen can be performed.

Wherein, for the convenience of operation, a pull ring 15 (see Fig. 4 ) is respectively provided on both sides of the chest 11 and the abdomen 12 exposed from the back plate 10, and the chest shield 21 and the abdomen protection A handle 27 is also provided on each side of the cover 22 .

Compared with the prior art, the present invention has more reasonable structure, better 360-degree protection effect, convenient use, flexible and fast combination, and low manufacturing and using cost. It greatly reduces the risk of carcinogenic, teratogenic and genetic diseases induced by radiation in infants and young children. Moreover, the head support 23 is made of transparent lead glass, which is more convenient to observe the child's breathing and facial conditions while reducing the feeling of oppression, so as to prevent sudden discomfort in the child during the scanning process, which is conducive to the timely handling of emergencies. To sum up, the present invention has very good popularization value.

The above description is only illustrative of the present invention, rather than restrictive. Those of ordinary skill in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined in the claims, but All will fall within the protection scope of the present invention.
