Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a CT scanning bed with a restraint structure. Background Art

[0002] CT scanning beds are an indispensable and important equipment in medical imaging diagnosis. They are mainly used to carry patients and cooperate with CT scanners to complete imaging scanning tasks. With the continuous development of medical imaging technology, CT scanning beds are also facing higher and higher requirements in design and function. Although traditional CT scanning beds can meet basic scanning needs, they still have some shortcomings in practical applications. Due to the differences in patient body shape, posture and scanning area, traditional CT scanning beds often lack sufficient restraint structures, which may cause patients to move or displace during the scanning process, thereby affecting the accuracy of the scanning results.

[0003] In the prior art, a CT scanning bed anti-fall restraint device disclosed in the patent with publication number CN208942173U includes a bed support and a sliding bed plate, the bed support is movably connected to the sliding bed plate, a sliding groove is provided on the sliding bed plate, a restraint device is fixed in the sliding groove, a sliding surface is provided inside the sliding bed plate, the sliding surface is connected to the sliding groove, a semicircular slideway is provided on the sliding surface, a threaded channel is provided on the side of the sliding bed plate, the threaded channel is connected to the slideway, and an adjustment device is provided on the side of the sliding bed plate; the restraint device includes a retractor, a buckle and a restraint belt, one end of the restraint belt is fixed on the retractor, the other end of the restraint belt can be plugged with the buckle, the retractor and the buckle are respectively placed in the slideway; the adjustment device includes a turntable, a screw, a ball bearing and an L-shaped connecting rod. The scanning bed is provided with a restraint device, the position of the restraint device can be freely adjusted to facilitate the exposure of the patient's CT scanning part, and the restraint device can be freely retracted and adaptively restrained according to the patient's body shape, and the restraint device can also perform radiation protection shielding on the non-CT scanning part.

[0004] Although the above patent can adaptively restrain the patient's body shape, its specific method is achieved through a retractor, a buckle and a restraint belt. Although the retractor can retract the restraint belt, so that the length of the restraint belt is adjustable and can be specifically adjusted according to the patient's body shape, for patients with larger body shapes, the tightness brought by the restraint belt will be more intense, and then the entire CT scanning process will cause discomfort to the patient. For this reason, the utility model provides a CT scanning bed with a restraint structure. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a CT scanning bed with a restraint structure, which solves the problem that the restraint belt of the previous CT scanning bed anti-restraint device will cause a stronger sense of tightness for patients with larger body sizes, thereby causing discomfort to the patients during the entire CT scanning process.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a CT scanning bed with a restraint structure, comprising a bed body, a restraint mechanism is arranged at the upper end of the bed body for fixing the patient's body, and the restraint mechanism includes:

[0007] The compression assembly is arranged on the upper part of the bed, and includes an arc-shaped gland that is rotatably mounted on one side of the upper part of the bed, and the other side of the bed is detachably connected to the arc-shaped gland. A filling air bag is bonded to the lower surface of the arc-shaped gland, and an inflation tube is installed on the upper part of the filling air bag. The inflation tube extends to the outside of the arc-shaped gland and a tube cover is screwed on the outer wall of the tube opening.

[0008] The air pressure control component is arranged on one side of the bed and is used to regulate the air pressure inside the filling air bag.

[0009] Preferably, the air pressure control assembly includes a T-shaped box body fixedly installed on one side of the bed body, a trapezoidal sealing block is slidably installed on the inner wall of the front end of the T-shaped box body, two groups of extrusion blocks are slidably installed on the inner wall of the rear end of the T-shaped box body, adjusting screws are threadedly connected on both sides of the rear end of the T-shaped box body, and the adjusting screws extend to the inner section of the T-shaped box body and are rotatably connected to a pressure plate, and a compression spring is installed between the extrusion block and the pressure plate.

[0010] Preferably, exhaust holes are provided on both sides of the front end of the T-shaped box body, and a sealing plate for sealing the exhaust holes is fixedly connected to one side of the trapezoidal sealing block.

[0011] Preferably, a hose is installed at the front end of the T-shaped box body, and the end of the hose is connected to the filling airbag.

[0012] Preferably, a clamping block is fixed on the outer edge of one side of the arc-shaped pressure cover, a clamping slot seat is fixed on the bed body at the same side end as the clamping block, and positioning holes for the clamping pin to pass through are provided on the clamping block and the clamping slot seat.

[0013] Preferably, a connecting hinge is installed on the same side end of the bed body and the arc-shaped pressure cover, so that the arc-shaped pressure cover can be turned over freely.

[0014] Beneficial Effects

[0015] The utility model provides a CT scanning bed with a restraint structure. Compared with the prior art, it has the following beneficial effects:

[0016] (1) The CT scanning bed with a restraint structure is designed with a restraint mechanism. Since the filling airbag at the bottom of the arc-shaped pressure cover has been injected with gas in advance, when the arc-shaped pressure cover is closed, the airbag fits the patient's upper body. Patients with larger bodies will squeeze the gas in the airbag out. Specifically, during the squeezing, the gas will first enter the hose from the airbag. Under the action of the air pressure, the trapezoidal sealing block will continue to move forward, and then push the extrusion blocks on both sides outward continuously through the inclined surface. The compression spring is compressed by force. At the same time, the trapezoidal sealing block will drive the sealing plate to move forward, and then expose the exhaust hole, so that the gas is discharged from the exhaust hole. When the air pressure reaches an appropriate value, the compression spring is reset, and then the sealing plate re-blocks the exhaust hole. The air pressure can be effectively adjusted, thereby effectively restraining patients of different body sizes.

[0017] (2) The CT scanning bed with a constraint structure can adjust the tightness of the compression spring appropriately by rotating the adjusting screw and then pushing the pressure plate to move horizontally. BRIEF DESCRIPTION OF THE DRAWINGS
