Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an X-ray protection device for a bone densitometer. Background Technology

[0002] A bone densitometer is a medical testing instrument used to measure bone mineral density and obtain various related data. The results are primarily based on the T-score, but also include the Z-score, bone mineral density, and bone mass. Dual-energy X-ray absorptiometry (DEXA) is considered the most accurate method and is the gold standard for bone density adopted by the World Health Organization (WHO). Bone densitometers are broadly classified into two categories: DEXA and ultrasound. During use, a protective shield is typically used to block X-rays to protect the user. However, due to varying body shapes, gaps can easily form between the shield and the user, allowing X-rays to escape and resulting in inadequate protection for areas not being tested. Therefore, X-ray protection devices for bone densitometers are proposed to improve protection. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides an X-ray protection device for a bone densitometer.

[0004] The technical solution adopted by this utility model to solve its technical problem is an X-ray protection device for a bone densitometer, including an examination bed. A lead curtain and an outer frame are provided above the examination bed. The outer frame is fixed to the top of the lead curtain and is fitted onto the X-ray scanner of the bone densitometer. Two limiting members are provided at the top of the outer frame.

[0005] By adopting the above technical solution, the outer frame can support the lead curtain, the limiting component can prevent the outer frame from shifting, the bottom of the lead curtain is lifted up, the examinee lies on the examination bed, the lead curtain is released, and the medical staff press the bottom of the lead curtain with their hands. The bottom of the lead curtain can fit the patient of different body types, thereby preventing X-rays from escaping and improving the protection effect on non-examination areas.

[0006] Specifically, the limiting component includes a card holder and an L-shaped insert. The card holder is connected to the outer frame. A stop block and an insert are provided on one side of the card holder. The stop block is fixed to the top of the X-ray scanner. A slot adapted to the end of the insert is provided on the side of the stop block near the insert. A handle is fixed to the top of the card holder. A crossbar is fixed to the side of the insert block near the handle. A through hole adapted to the crossbar is opened on the handle. A spring is sleeved on the crossbar. A pressure block is fixed to the end of the crossbar away from the insert.

[0007] By adopting the above technical solution, by holding the two handles and pressing the two pressure blocks, the two pressure blocks drive the two crossbars to move, and the ends of the two inserts disengage from the slots on the two stops. Lifting the two handles allows the outer frame, the card holder, and the lead curtain to be removed together, which facilitates the maintenance of the X-ray scanner and the lead curtain.

[0008] Specifically, the side of the pressure block away from the insertion block is integrally formed with multiple anti-slip protrusions.

[0009] By adopting the above technical solution, the anti-slip protrusions facilitate pressing the block.

[0010] Specifically, two fabric pieces are fixed on both sides of the outer frame, and each fabric piece is fixed with a Velcro female part, while two Velcro male parts are fixed on both sides of the lead curtain.

[0011] By adopting the above technical solution, when the lead curtain is not in use, the bottom of the lead curtain can be lifted upwards, and the setting of the fabric piece, the male part of the Velcro and the female part of the Velcro makes it convenient to store the lead curtain.

[0012] Specifically, the lead curtain is connected to the outer frame by an adhesive, and the outer frame is made of lead.

[0013] The beneficial effects of this utility model are:

[0014] (1) The X-ray protection device of the bone densitometer described in this utility model has an outer frame that can support the lead curtain, and a limiting component that can prevent the outer frame from shifting. When the bottom of the lead curtain is lifted up, the examinee lies on the examination bed, the lead curtain is released, and the medical staff presses the bottom of the lead curtain with their hands. The bottom of the lead curtain can fit the patient of different body types, thereby preventing X-rays from escaping and improving the protection effect on non-examined areas.

[0015] (2) The X-ray protection device of the bone densitometer described in this utility model allows you to hold two handles and press two pressure blocks. The two pressure blocks drive two crossbars to move, and the ends of the two inserts disengage from the slots on the two stops. Lifting the two handles allows you to remove the outer frame, the card holder, and the lead curtain together, which is convenient for the maintenance of the X-ray scanner and the lead curtain.
