Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a radiation protection isolation device for CT scanning. Background Art

[0002] CT scanning is a medical imaging technology that uses precisely collimated X-ray beams, gamma rays, ultrasound, etc., together with highly sensitive detectors to scan sections of a certain part of the human body one by one, forming continuous layer images to display the internal structure and lesions of the human body. In CT scanning, since X-rays will directly irradiate the human body, they will cause damage to human tissues and cells.

[0003] To solve the above problems, when patients seek medical treatment for examination, medical staff will ask patients to wear protective clothing or cover them with protective equipment to reduce the radiation range. For example, patent application CN108523919A discloses a CT scanning protection device. The patent uses the first and second radiation shields to reduce the radiation in other positions, and the positions of the first radiation shield and the second radiation shield can be adjusted by sliding the movable seat, the first slider and the second slider. It is easy to use, but the protection device disclosed in the patent cannot adjust the size of the protection range according to the specific detection needs of the human body, and cannot cover the parts of the human body that do not need to be scanned, resulting in the inevitable radiation to human tissues and cells during CT scanning. Therefore, it is necessary to design an isolation device that can adjust the size of the protection range according to the specific detection needs of the human body to avoid radiation to tissues and cells in non-detected parts of the human body. Utility Model Content

[0004] The utility model aims to solve the problems existing in the prior art and provide a radiation protection isolation device for CT scanning.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A radiation-proof isolation device for CT scanning comprises a flat plate and a base; the flat plate is mounted on the base and partially suspended in the air, a radiation-proof isolation area is provided in the suspended part, and a CT scanning window with adjustable size is provided in the radiation-proof isolation area.

[0007] As the preferred technical solution:

[0008] In the radiation protection isolation device for CT scanning as described above, the flat panel and the CT scanning window are both rectangular.

[0009] A radiation protection isolation device for CT scanning as described above, the flat plate comprises two strips, a left sliding beam, a right sliding beam, a left protective cloth 1 and a right protective cloth 1;

[0010] The two strips are arranged horizontally, with their length directions parallel to the left-right direction and spaced apart in the front-back direction;

[0011] The left sliding beam and the right sliding beam are arranged horizontally, parallel to the front-rear direction and spaced apart in the left-right direction; the left sliding beam is slidably connected to the two strips at the same time, and the sliding direction is the left-right direction; the right sliding beam is slidably connected to the two strips at the same time, and the sliding direction is the left-right direction;

[0012] On the left side of the left sliding beam, the area between the two strips is covered by a left protective cloth 1, which consists of a left part and a right part, wherein the left part is fixedly connected to the two strips, the right part is not connected to the two strips, and the right end of the right part is fixedly connected to the left sliding beam;

[0013] On the right side of the right sliding beam, the area between the two strips is covered by a right protective cloth 1, which consists of a left and a right part, the left part is not connected to the two strips, the right part is fixedly connected to the two strips, and the left end of the left part is fixedly connected to the right sliding beam;

[0014] The sliding adjustment of the left and right sliding beams moving closer to each other can drive the parts of the left and right protective cloths that are not connected to the two strips to stretch and tighten, thereby reducing the CT scanning radiation cross-sectional range. The sliding adjustment of the left and right sliding beams moving away from each other can drive the parts of the left and right protective cloths that are not connected to the two strips to relax and droop downward, thereby expanding the CT scanning radiation cross-sectional range. In this way, only the local lesion position of the human body can be scanned and detected, while avoiding blocking of the parts that do not need to be scanned, thereby preventing the human body from unnecessary radiation.

[0015] In the radiation protection isolation device for CT scanning as described above, vertically arranged handles are provided at the front and rear ends of the left sliding beam and the right sliding beam, so as to facilitate the sliding adjustment of the left sliding beam and the right sliding beam towards or away from each other.

[0018] n extension rods are arranged horizontally, with their length direction parallel to the left-right direction and arranged at intervals along the front-back direction, n≥4;

[0019] n extension rods are located above the right sliding beam; the left ends of the first extension rod and the nth extension rod are fixedly connected to the left sliding beam, and the left ends of the other extension rods are slidably connected to the left sliding beam and the sliding direction is the front-back direction; the right ends of the n extension rods are located on the right side of the right sliding beam;

[0020] There is no protective cloth 2 between the mth extension rod and the m+1th extension rod, and there is protective cloth 2 between any other two adjacent extension rods, where m is a positive integer in the interval (1, n-1);

[0021] The mth extension rod and the m+1th extension rod are adjusted closer to each other to reduce the CT scanning radiation cross-sectional range, and the mth extension rod and the m+1th extension rod are adjusted away from each other to expand the CT scanning radiation cross-sectional range. The mth extension rod, the m+1th extension rod, the left sliding beam, and the right sliding beam together form a CT scanning window. By adjusting the gap between the mth extension rod and the m+1th extension rod and the gap between the left sliding beam and the right sliding beam, the size of the CT scanning window can be accurately adjusted.

[0022] As described above, in a radiation protection isolation device for CT scanning, each protective cloth 2 is adhered with lead sheets 2 distributed in a matrix, and two adjacent lead sheets 2 are hinged. The lead sheets 2 can improve the radiation protection performance of the protective cloth 2. The distribution and connection of the lead sheets 2 are designed in such a way that the lead sheets 2 can be deformed along with the protective cloth 2.

[0023] In a radiation protection isolation device for CT scanning as described above, the left ends of the other extension rods are slidably connected to the left sliding beam through the inverted T-slots and the I-shaped parts that cooperate with each other; the inverted T-blocks on the bottom walls of the sliders of the first extension rod and the nth extension rod are fixedly connected to the inner walls of the inverted T-slots, so that the synchronous movement of all the extension rods can be controlled by only controlling the sliders connecting the first extension rod and the nth extension rod to slide back and forth on the left sliding beam; the inverted T-slot is arranged on the left sliding beam, and the I-shaped part is composed of a slider and an inverted T-block, the left end of the extension rod is fixedly connected to the slider, and the inverted T-block is slidably engaged with the inverted T-slot; when the extension rod drives the second protective cloth to adjust horizontally, the inverted T-block slides horizontally along the inverted T-slot, so that the second protective cloth can be quickly unfolded and tensioned and recovered in a relaxed state.

[0024] In the radiation protection isolation device for CT scanning as described above, a vertically arranged handle 2 is provided on the slider connected to the left end of the mth extension rod and the slider connected to the left end of the m+1th extension rod, so as to facilitate the adjustment of the two extension rods 35 to move closer to or away from each other.

[0025] In the radiation protection isolation device for CT scanning as described above, the plate further comprises two support beams, two strip guide plates and two I-shaped shafts;

[0026] The two support beams are arranged horizontally, parallel to the left-right direction and spaced apart in the front-back direction;

The counterweight seat can counterweight the overall structure to prevent tipping, and keep the guide seat in a vertical state and motionless.

[0032] In the radiation protection isolation device for CT scanning as described above, symmetrically distributed L-shaped support parts are arranged on both sides of the upper end of the guide seat, and sliding notches with isosceles trapezoidal cross-sections are opened at the upper ends of the two L-shaped support parts; the two support beams are respectively slidably engaged with the sliding notches on the two L-shaped support parts, and the sliding engagement can ensure that the two strip guide plates are in a suspended horizontal state, and can also adjust the protective position of the left and right protective cloths by driving the conveyor belt between the two I-shafts; before performing a CT scan, when the patient lies flat on the examination bed, the support beam can be used to slide horizontally along the sliding notch of the L-shaped support part of the guide seat, and then the left and right protective cloths located between the two conveyor belts can be moved and adjusted to be directly above the patient's body without contacting the patient's body, which has the advantage of avoiding bacterial infection caused by contact between the protective cloth and the human body and cross infection between patients.

[0033] Beneficial effects:

[0034] The utility model can adjust the portions of the two protective fabrics that are not connected to the two strips to be stretched and tightened or to be relaxed and drooped downward by adjusting the sliding of the left and right sliding beams toward or away from each other, thereby adjusting the longitudinal cross-sectional range of the CT scanning radiation. By adjusting the sliding of the mth extension rod and the m+1th extension rod toward or away from each other, the gap between the mth extension rod and the m+1th extension rod is adjusted, thereby adjusting the cross-sectional range of the CT scanning radiation.
