Description

Technical Field

[0001] The utility model relates to the technical field of medical protection, in particular to a non-examination part protection device for CT examination. Background Art

[0002] CT examination is a relatively advanced medical imaging examination technology in modern times. CT examination generally includes plain CT scan, enhanced CT scan and cisternography CT. CT uses X-ray beams to scan a certain thickness of a certain part of the human body. The X-rays that pass through the layer are received by the detector, converted into visible light, and then converted into electrical signals by photoelectric conversion. The signals are then converted into digital signals by an analog-to-digital converter and input into a computer for processing.

[0003] Some patients undergo local examinations of their bodies during CT examinations. Therefore, a baffle is set directly above the examination bed, leaving a space for the patient to lie flat between the baffle and the examination bed, so that the patient is located between the baffle and the examination bed, and the baffle effectively blocks the X-ray beam, thereby shielding the parts that do not need to be examined, thereby reducing the radiation received by the patient.

[0004] However, in actual use, the patient needs to lie on the examination bed before undergoing a CT scan. However, since the baffle is located directly above the examination bed, the patient will be blocked by the baffle if he lies down directly, so the patient can only enter between the baffle and the examination bed in other ways, such as crawling between the baffle and the examination bed, and then adjusting to a lying position to wait for the examination. This method is cumbersome because the patient cannot lie down directly. On the other hand, it is difficult for some patients with limited mobility to enter between the baffle and the examination bed. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a non-examination part protection device for CT examination, so as to solve the problem that the existing examination bed is provided with a baffle for protecting the parts of the patient that do not need to be examined, but the patient will be blocked by the baffle when lying down directly, causing a certain degree of inconvenience.

[0006] The utility model is achieved through the following technical solutions:

[0007] A non-examination part protection device for CT examination includes a shell mounted on an examination bed, the shell being a semicircular structure with a downward depression in the middle, and two ends of the shell being located on either side of the examination bed;

[0008] A receiving cavity is provided in the shell, and a semicircular baffle is slidably fitted in the receiving cavity;

[0009] One end of the shell is provided with a through opening connected to the storage cavity, one end of the baffle can slide out of the storage cavity through the through opening and connect to the other end of the shell, and a space for the patient to lie flat is formed between the baffle and the examination bed.

[0010] It is further defined that the examination bed is further provided with a receiving groove for installing the shell, the receiving groove extends along the length direction of the examination bed, and the shell can slide along the length direction of the receiving groove.

[0011] It is further defined that a roller is provided in the accommodating groove, the roller is rotatably mounted on the bottom surface of the shell, and the wheel surface of the roller abuts against the surface of the accommodating groove.

[0012] It is further defined that an insertion portion is provided at one end of the baffle plate close to the through opening, and the insertion portion penetrates along the thickness direction and forms a card slot;

[0013] The end of the shell without a through-hole is provided with a socket for inserting the insertion part, and a through hole is provided on the arc surface of the shell, the through hole passes through the shell and is connected to the socket, and when the insertion part is inserted into the socket, the through hole and the card slot are located at the same horizontal plane;

[0014] A plurality of first screw holes are formed on the side wall of the examination bed, and the plurality of first screw holes are arranged along the length direction of the examination bed.

[0015] It is further defined that two baffles and two shells are arranged opposite to each other at two ends of the examination bed.

[0016] It is further defined that a protective cover is provided between the two baffles, and two ends of the protective cover are respectively connected to the two baffles.

[0017] It is further defined that a storage cavity and a connecting groove for storing the protective cover are respectively provided on opposite sides of the two baffles, and the storage cavity and the connecting groove both extend in the length direction of the baffle.

[0018] The beneficial effects of the present invention are:

[0019] When not in use, the baffle is located in the storage cavity on the shell. In this state, the area directly above the examination bed will not be blocked by the baffle, so the patient can lie down directly. On the one hand, this method prevents the baffle from blocking the patient from lying down. On the other hand, the baffle can be stored in the shell through the sliding fit between the baffle and the storage cavity, which can effectively reduce space occupancy.

Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0033] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted. The term "perpendicular" simply refers to the positional relationship between components being more perpendicular than "parallel," not that the structure must be perfectly vertical; rather, it can be slightly tilted.

[0034] See also Figure 1-6 The present invention provides a technical solution: a non-examination part protection device for CT examination, comprising a shell 2 mounted on an examination bed 1, wherein the shell 2 is a semicircular structure with a downward depression in the middle, and the two ends of the shell 2 are respectively located on both sides of the examination bed 1;

[0035] The housing 2 is provided with a receiving cavity 201, and a semicircular baffle 3 is slidably fitted in the receiving cavity 201;

[0036] One end of the shell 2 is provided with a through opening connected to the storage chamber 201, and one end of the baffle 3 can slide out of the storage chamber 201 through the through opening and connect to the other end of the shell 2, and a space for the patient to lie flat is formed between the baffle 3 and the examination bed 1.

[0037] In this solution, the baffle and the shell can form the following two states:

[0038] State 1: The baffle 3 is located in the receiving cavity 201 on the housing 2. In this state, the baffle 3 will not block the examination bed 1 directly above it, so that the patient can lie down directly.

[0039] In the second state, the baffle 3 and the housing 2 form a ring. In this state, the baffle 3 covers the area above the patient, thereby protecting the covered area.

[0040] During specific use, the baffle 3 and the shell 2 are first adjusted to position 1, and then the patient lies on the examination bed 1 and adjusts his posture to lie flat so that the non-examination part of the patient is opposite to the shell 2. Then, the operator pulls one end of the baffle 3 to make the baffle 3 as a whole gradually slide out of the storage cavity 201 until it is flipped over to just above the examination bed 1, so that the baffle 3 is located above the non-examination part of the patient, thereby protecting the non-examination part of the patient;

[0041] The baffle 3 is a plate made of lead or a plate with a lead plate embedded therein.

[0042] This method not only prevents the baffle 3 from obstructing the patient from lying down, but also allows the baffle 3 to be accommodated in the housing 2 through sliding cooperation with the storage cavity 201, thereby effectively reducing space occupation.

[0043] At the same time, in order to better achieve the above technical effects, the arc length of the baffle 3 is greater than the arc length of the shell 2. Specifically, when the baffle 3 is in the retracted state, one end of the baffle 3 protrudes from the shell 2 through the opening for the operator to grasp, thereby facilitating the operator to pull out the baffle 3.

[0044] Because the shell 2 and the baffle 3 are both incomplete annular structures and are coaxially installed, the axes of both are on the bed surface of the examination bed 1. Therefore, when the baffle 3 slides along the circumferential direction of the shell 2, the baffle 3 also rotates around the examination bed 1, so that the sliding trajectory of the baffle 3 can be limited by the shell 2.

[0045] In this embodiment, the examination bed 1 is further provided with a receiving groove 101 for mounting the shell 2 . The receiving groove 101 extends along the length direction of the examination bed 1 , and the shell 2 can slide along the length direction of the receiving groove 101 .

[0046] Because the shell 2 is installed in the receiving groove 101 and is not fixedly connected, the shell 2 can slide along the length direction of the receiving groove 101 (which is also the length of the examination bed 1), thereby adjusting the position of the shell 2 and the baffle 3 to slide to the part that needs protection.

[0047] The examination bed 1 is provided with guide slots extending along its length on both sides. Guide blocks are provided on opposite sides of the housing 2, each inserted into the guide slots. The guide blocks slide in and out of the slots. Due to the semicircular structure of the housing 2, the housing 2 lacks stability during sliding and is prone to self-rotation. By connecting one end of the guide block to the end of the housing 2 and inserting the other end into the guide slot, the housing 2 is restrained, preventing rotation and providing greater stability during sliding.

[0048] In this embodiment, a roller 4 is provided in the receiving groove 101 . The roller 4 is rotatably mounted on the bottom surface of the housing 2 , and the wheel surface of the roller 4 abuts against the surface of the receiving groove 101 .

[0049] The housing 2 is supported as a whole in the receiving groove 101 by the roller 4 (eg Figure 6 As shown), when the housing 2 is adjusted, the roller 4 rolls on the surface of the receiving groove 101, thereby reducing the friction between the housing 2 and the receiving groove 101 and increasing the service life of both.

[0050] In this embodiment, an insertion portion 301 is provided at one end of the baffle 3 close to the through opening. The insertion portion 301 penetrates along the thickness direction and forms a slot 302.

[0051] The end of the housing 2 without a through opening is provided with a socket 202 for inserting the insertion portion 301. A through hole 203 is provided on the curved surface of the housing 2. The through hole 203 passes through the housing 2 and is connected to the socket 202. When the insertion portion 301 is inserted into the socket 202, the through hole 203 and the card slot 302 are located at the same horizontal plane.

[0052] A plurality of first screw holes 102 are defined on the side wall of the examination bed 1 , and the plurality of first screw holes 102 are arranged along the length direction of the examination bed 1 .

[0053] First, after the housing 2 and the baffle 3 are properly adjusted, the first screw holes 102 on the housing 2 and the examination bed 1 are aligned.

[0054] Then, the operator pulls the baffle 3 to flip it out of the housing 2. When the baffle 3 flips to the limit position, the inserting portion 301 at the end of the baffle 3 will be inserted into the socket 202 (such as Figure 3 shown);

[0055] The operator first inserts a rubber bolt into the through-hole 203 on the housing 2 and moves it toward the examination bed 1. During this process, the rubber bolt passes through the retaining groove 302 on the insertion portion 301 until it contacts the first screw hole 102 on the examination bed 1. At this point, the rubber bolt is rotated to engage with the first screw hole 102, thereby securing the housing 2 and baffle 3. In this secured state, the housing 2 cannot slide further along the length of the examination bed 1, and the baffle 3 cannot slide along the circumference of the housing 2.

[0056] In this embodiment, two baffles 3 and two shells 2 are disposed opposite to each other at two ends of the examination bed 1 .

[0057] By providing two shells 2 and two baffles 3 on the examination bed 1, multiple parts of the patient can be effectively protected, and the multiple parts can be effectively protected when they are far apart. For example, the two baffles 3 can protect the patient's head and feet respectively.

[0058] In this embodiment, a protective cover 5 is provided between the two baffles 3 , and two ends of the protective cover 5 are respectively connected to the two baffles 3 .

[0059] In this embodiment, a storage cavity 6 and a connecting groove 7 for storing the protective cover 5 are respectively provided on opposite sides of the two baffles 3. The storage cavity 6 and the connecting groove 7 both extend in the length direction of the baffle 3. The protective cover 5 is located in the storage cavity 6 and a connecting block 501 is provided at one end. The protective cover 5 can slide along the length direction of the baffle 3 until the connecting block 501 is inserted into the connecting groove 7. The connecting block 501 and the connecting groove 7 both have a second screw hole 8 along the height direction.

[0060] The protective cover 5 is a foldable cover that can be retracted or unfolded along the length direction of the examination bed 1, and the cover surface of the protective cover 5 is lead cloth;

[0061] In the natural state, the protective cover 5 is located in the storage chamber 6. In this state, the protection range of the patient depends only on the coverage area of ​​the two baffles 3 on the patient.

[0062] When the area of ​​the patient to be protected is large, for example, when only the lower body of the patient is to be examined, the two baffles 3 can be slid to the upper body area of ​​the patient, and the connecting block 501 can be pulled to move the protective cover 5 out of the storage chamber 6. As the operator pulls the connecting block 501, the protective cover 5 gradually unfolds (such as Figure 2 As shown), thereby expanding the protection range of the patient through the protective cover 5;

[0063] The operator inserts the connecting block 501 into the connecting slot 7, aligns the connecting block 501 with the second screw holes 8 on the connecting slot 7, and uses rubber bolts to threadably engage with the two second screw holes 8 to fix the movement state of the protective cover 5 so that it cannot shrink or expand.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
