To make it easier for patients to lie on the examination bed, a manually operated pull-out foot pedal with casters is typically placed at the bottom. In use, the foot pedal is manually pulled out from under the examination bed, and the casters facilitate its sliding during this process. However, in developing this invention, the inventors discovered the following problem with the existing technology: when a patient steps on the foot pedal, the pedal can slip due to the pressure exerted by the foot, posing a safety hazard. Summary of the Invention

[0003] This application provides a diagnostic bed with a foot pedal to solve the problems existing in related technologies. The technical solution is as follows:

[0004] This application provides a foot pedal examination bed, including a bed frame and a foot pedal mechanism. The bottom of the bed frame has a receiving cavity, and the foot pedal mechanism is placed in the receiving cavity. The foot pedal mechanism includes a pull-out box and a pull-out rail assembly. The pull-out box is slidably connected to the bed frame through the pull-out rail assembly, and the pull-out box can slide relative to the bed frame. Pressure-bearing brake casters are installed at the four corners of the bottom of the pull-out box. When the patient's foot is on the pull-out box, the pressure-bearing brake casters are in a braking state.

[0005] In one embodiment, the foot pedal mechanism further includes an electric push rod. The bed has a rear side plate, the electric push rod is fixed to the rear side plate, and the electric push rod is connected to the pull-out box. The electric push rod pushes the pull-out box out of the receiving cavity or pulls it in.

[0006] In one embodiment, the foot pedal mechanism further includes an infrared sensor, and a pull-out plate is fixed to the front side of the pull-out box, with the infrared sensor fixed to the pull-out plate.

[0007] In one embodiment, the foot pedal mechanism further includes a cable guide assembly, which includes a cable guide tube. One end of the cable guide tube is fixed to the rear side panel of the bed, and the other end of the cable guide tube passes through the rear side panel of the pull-out box and is placed inside the pull-out box. The wire of the infrared sensor passes through one end of the cable guide tube and exits from the other end to connect with the infrared sensor.

[0008] In one embodiment, the conduit assembly further includes a fixing plate, which is fixed to the rear side plate of the bed, and one end of the conduit is fixed to the fixing plate.

[0009] In one embodiment, a pull-out plate is fixed to the front side of the pull-out box, and a pull-out handle is fixed to the pull-out plate.

[0010] In one embodiment, the footrest-equipped examination bed also includes a pull-out frame, with a pull-out box nested inside the pull-out frame, and the pull-out frame is slidably connected to the bed frame via a pull-out track assembly.

[0011] In one embodiment, the pull-out frame includes a pull-out rear side panel, a pull-out front side panel, and two pull-out side panels. The two pull-out side panels are arranged opposite to each other, and the pull-out front side panel and the pull-out rear side panel are arranged opposite to each other. The two ends of the pull-out front side panel and the pull-out rear side panel are respectively connected to the two pull-out side panels. The pull-out box is located between the pull-out front side panel, the pull-out rear side panel, and the two pull-out side panels.

[0012] In one embodiment, the pull-out frame further includes a pull-out base plate, the opposite ends of which are connected to the front pull-out side plate and the rear pull-out side plate, respectively. The two sides of the pull-out base plate each have a travel through hole, and the pressure-bearing brake caster protrudes from the bottom of the pull-out frame after passing through the travel through hole.

[0013] In one embodiment, there is a gap between the bottom of the pull-out box and the pull-out base plate.

[0014] The advantages or beneficial effects of the above technical solutions include at least the following:

[0015] The foot-operated examination bed of this application includes a bed frame and a foot pedal mechanism. The pull-out housing of the foot pedal mechanism is slidably connected to the bed frame via a pull-out rail assembly, and a pressure-bearing brake caster is installed at the bottom of the pull-out housing. When the foot pedal mechanism is needed, the pull-out housing is pulled out from the receiving cavity at the bottom of the bed frame, and the patient can climb onto the examination bed by stepping on the pull-out housing. Because the pressure-bearing brake caster is installed at the bottom of the pull-out housing, and the pressure-bearing brake caster is in a braking state when the patient's foot is on the pull-out housing, the movement of the pull-out housing can be prevented, thus avoiding safety hazards caused by the movement of the pull-out housing.

[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0029] Example 1

[0030] like Figures 1 to 6 As shown, this embodiment discloses an examination bed with a foot pedal, including a bed body 1 and a foot pedal mechanism 2, which is electrically powered. The bottom of the bed body 1 has a receiving cavity, and the foot pedal mechanism 2 is placed within the receiving cavity. The foot pedal mechanism 2 includes a pull-out housing 20 and a pull-out rail assembly 21. The pull-out housing 20 is slidably connected to the bed body 1 via the pull-out rail assembly 21. Pressure-bearing brake casters 3 are respectively installed at the four corners of the bottom of the pull-out housing 20. Preferably, the braking weight of a single pressure-bearing brake caster 3 is 5KG, and the braking distance is 6mm.

[0031] The aforementioned pull-out box 20 of the footrest examination bed is housed within the receiving cavity when not in use. When needed, the pull-out box 20 is pushed out of the receiving cavity to be used as a footrest, allowing the patient to climb onto the examination bed by stepping on the pull-out box 20. Because the bottom of the pull-out box 20 is equipped with pressure-bearing casters 3, which are braked when the patient's feet are on the pull-out box 20, movement of the pull-out box 20 is prevented, thus avoiding safety hazards caused by movement.

[0032] In one embodiment, the pressure-bearing brake caster can be the pressure-bearing brake caster disclosed in patent CN215321772U. In use, the top end of the insert rod on the caster is inserted into the pull-out housing 20. The pull-out housing 20 has a socket for use with the insert rod, and the caster is fixed to the bottom of the pull-out housing 20 through the insert rod and the socket. When the insert rod is under pressure, it drives the caster housing downwards, which in turn drives the main frame downwards. The caster adheres to the ground, the crossbar slides upwards in the through hole, and the pressure block inside the main frame moves downwards. The bottom end of the pressure block has a sloping protrusion, and the same position on the caster below it has a sloping concave tooth. When pressure is applied, the sloping protrusion engages with the sloping concave tooth, causing the caster to stop and achieving a braking effect.

[0033] In another embodiment, the pressure-bearing brake caster may also be a brakeable caster structure disclosed in patent publication number CN216268475U. After the brakeable caster structure is installed on the bottom of the pull-out box 20, when the patient's foot is on the pull-out box 20, because the rotating wheel of the brakeable caster structure is made of soft rubber, the rotating wheel can contract and deform in the vertical direction when it is subjected to vertical force and pressed against the ground, thereby causing the brake stop at the bottom of the wheel frame to abut against the ground, thus restricting the rotation of the wheel.

[0034] When the brakeable caster structure is connected to the pull-out box 20, a fixing plate can be welded to the top of the wheel frame, and the fixing plate is installed at the bottom of the pull-out box 20 by bolts.

[0035] The pressure-bearing brake caster in this embodiment can also be any existing caster that can achieve braking function when subjected to pressure. The connection method between the caster and the pull-out box 20 can be any existing connection method, without specific limitation.

[0036] To allow the pull-out box 20 to be pushed out of the receiving cavity, the foot pedal mechanism 2 also includes an electric push rod 22. The bed body 1 has a rear side plate, and the electric push rod 22 is fixed to the rear side plate. The push rod of the electric push rod 22 is connected to the pull-out box 20, and the electric push rod 22 pushes the pull-out box 20 out or pulls it into the receiving cavity. Preferably, the electric push rod 22 is a conventional electric push rod. When it is necessary to push the pull-out box 20 out, the electric push rod 22 is activated, and the electric push rod 22 pushes the pull-out box 20 to slide out; when it is necessary to pull the pull-out box 20 into the receiving cavity, the electric push rod 22 is activated again, and the electric push rod 22 pulls the pull-out box 20 to slide into the receiving cavity.

[0037] A foot pedal 23 is bolted to the top of the pull-out box 20, and a pull-out plate 24 is bolted to the front of the pull-out box 20. To prevent the pull-out box 20 from colliding with patients or medical personnel when it is pushed out, the foot pedal mechanism 2 also includes an infrared sensor 25. The infrared sensor 25 is fixed to the pull-out plate 24. The infrared sensor 25 can be fixed to the pull-out plate 24 by screws or the like, or the pull-out plate 24 has mounting holes in which the infrared sensor 25 is directly installed. During the extension of the pull-out box 20, the infrared sensor 25 senses that someone is approaching. If the infrared sensor 25 senses someone approaching, the electric push rod 22 stops the extension of the pull-out box 20. When the person leaves, the electric push rod 22 continues to push the pull-out box 20. Preferably, the sensing distance of the infrared sensor 25 can be set to within one meter, and the sensing distance of the infrared sensor 25 can be adjusted according to usage requirements.

[0038] The electric push rod 22 and the infrared sensor 25 are connected to the power supply via wires. To avoid excessive tangling of the wires, the foot pedal mechanism 2 in this embodiment also includes a cable guide assembly 26. The cable guide assembly 26 includes a cable guide 260, one end of which is fixed to the rear side panel of the bed frame 1, and the other end of which passes through the rear side panel of the pull-out box 20 and is placed inside the pull-out box 20. The wire of the infrared sensor 25 passes through one end of the cable guide 260 and exits from the other end, connecting to the infrared sensor 25. This embodiment protects the wire of the infrared sensor 25 by placing it inside the cable guide 260, and also avoids excessive tangling of the wires inside the pull-out box 20.

[0039] In order to connect the conduit 260 to the bed body 1, the conduit assembly 26 also includes a fixing plate 261. The fixing plate 261 is fixed to the rear side plate of the bed body 1 by bolts, and one end of the conduit 260 can be welded to the fixing plate 261.

[0040] The footrest-equipped examination bed in this embodiment also includes a pull-out frame 27, and a pull-out box 20 is nested inside the pull-out frame 27. The pull-out frame 27 is slidably connected to the bed 1 through a pull-out track assembly 21. When the pull-out frame 27 slides, it drives the pull-out box 20 to slide.

[0041] The pull-out frame 27 includes a pull-out rear side panel 270, a pull-out front side panel 271, and two pull-out side panels 272. The two pull-out side panels 272 are arranged opposite to each other, and the pull-out front side panel 271 and the pull-out rear side panel 270 are arranged opposite to each other. The two ends of the pull-out front side panel 271 and the pull-out rear side panel 270 are respectively connected to the two pull-out side panels 272. The pull-out rear side panel 270, the pull-out front side panel 271, and the two pull-out side panels 272 are connected and fixed together by bolts. The pull-out housing 20 is located between the pull-out front side panel 271, the pull-out rear side panel 270, and the two pull-out side panels 272. The pull-out plate 24 is placed above the pull-out front side panel 271 and in front of the two pull-out side panels 272. The pull-out front side panel 271 is placed between the pull-out plate 24 and the front side panel of the pull-out housing 20. The two pull-out side panels 272 are slidably connected to the bed body 1 via the pull-out track assembly 21.

[0042] The pull-out frame 27 also includes a pull-out base plate 273. The opposite ends of the pull-out base plate 273 are connected to the front pull-out side plate 271 and the rear pull-out side plate 270 respectively via bolts. Each side of the pull-out base plate 273 has a through hole 274. A pressure-bearing brake caster 3 passes through the through hole 274 and protrudes from the bottom of the pull-out frame 27. An electric push rod 22 is connected to the rear pull-out side plate 270. As the electric push rod 22 moves the rear pull-out side plate 270, it causes the pull-out box 20 to slide via the pull-out frame 27. During this sliding process, the pull-out box 20 moves on the ground via the pressure-bearing brake caster 3.

[0043] There is a gap between the bottom of the pull-out box 20 and the pull-out base plate 273. When a foot is placed on the pull-out box 20, the pull-out box 20 and the pressure brake caster 3 bear the weight of the patient.

[0044] In one embodiment, the electric push rod 22 can be controlled by a remote control switch or a wall switch. The pull-out rail assembly 21 is a three-section guide rail, and the pull-out frame 27 is slidably connected to the bed frame 1 via the three-section guide rail. The three-section guide rail can be the same three-section guide rail used in existing drawers, and the three-section guide rail is fixed to the bed frame 1 with screws.

[0045] It should be noted that the aforementioned pressure-bearing brake caster 3, electric push rod 22 and infrared sensor 25 are all existing technologies, and this application does not involve any improvement to the structure of the above-mentioned components.

[0046] Example 2

[0047] The following refers to Example 1 and Figures 1 to 6This embodiment will be described as follows:

[0048] This embodiment also discloses a diagnostic bed with a footrest, such as Figure 7 , Figure 8 As shown, the foot-operated examination bed of this embodiment includes a bed body 1 and a foot pedal mechanism 2. A receiving cavity is provided at the bottom of the bed body 1, and the foot pedal mechanism 2 is placed within the receiving cavity. The foot pedal mechanism 2 includes a pull-out box 20 and a pull-out rail assembly 21. The pull-out box 20 is slidably connected to the bed body 1 via the pull-out rail assembly 21, and pressure-bearing brake casters 3 are respectively installed at the four corners of the bottom of the pull-out box 20. Preferably, the braking weight of a single pressure-bearing brake caster 3 is 5KG, and the braking distance is 6mm. The structures of the bed body 1, the pull-out rail assembly 21, and the pressure-bearing brake casters 3 are the same as in Embodiment 1.

[0049] The footrest-equipped examination bed in this embodiment also includes a pull-out frame 27, with a pull-out housing 20 nested inside the pull-out frame 27. The pull-out frame 27 is slidably connected to the bed frame 1 via a pull-out track assembly 21, and the pull-out frame 27 drives the pull-out housing 20 to slide when it slides. The pull-out frame 27 has the same structure as in Embodiment 1. The pull-out frame 27 includes a pull-out rear side plate 270, a pull-out front side plate 271, and two pull-out side plates 272. The two pull-out side plates 272 are arranged opposite to each other, and the pull-out front side plate 271 and the pull-out rear side plate 270 are arranged opposite to each other. The two ends of the pull-out front side plate 271 and the pull-out rear side plate 270 are respectively bolted to the two pull-out side plates 272. The pull-out housing 20 is located between the pull-out front side plate 271, the pull-out rear side plate 270, and the two pull-out side plates 272. A pull-out plate 24 is placed above the pull-out front side plate 271 and in front of the two pull-out side plates 272. The pull-out front side panel 271 is positioned between the pull-out plate 24 and the front side panel of the pull-out box 20. The two pull-out side panels 272 are slidably connected to the bed body 1 via the pull-out track assembly 21.

[0050] The pull-out frame 27 also includes a pull-out base plate 273. The opposite ends of the pull-out base plate 273 are bolted to the front pull-out side plate 271 and the rear pull-out side plate 270, respectively. Each side of the pull-out base plate 273 has a walking through hole 274. A pressure-bearing brake caster 3 passes through the walking through hole 274 and protrudes from the bottom of the pull-out frame 27. The pull-out box 20 moves on the ground during sliding via the pressure-bearing brake caster 3. There is a gap between the bottom of the pull-out box 20 and the pull-out base plate 273. When a foot steps on the pull-out box 20, the pull-out box 20 and the pressure-bearing brake caster 3 bear the patient's weight.

[0051] Unlike Embodiment 1, a pull handle 28 is fixed to the pull plate 24 to facilitate the pulling out of the drawer body 20. The draw handle 28 is used to pull out and push the drawer body 20. The pull handle 28 and the drawer body 20 are connected and fixed by screws.

[0052] Compared to Embodiment 1, the advantages of this embodiment are as follows: Embodiment 1 uses an electric push rod 22 to control the sliding of the pull-out box 20. The electric push rod 22 is relatively expensive, and the process of pushing out and pulling in the pull-out box 20 is relatively slow, taking about half a minute. However, by changing to manual operation, the process of pulling out and pushing in the pull-out box 20 can be accelerated, reducing the cost of the examination bed.
