Description

Technical Field

[0001] This utility model relates to the field of medical technology, specifically a flatbed cart with a retractable shielding device. Background Technology

[0002] When hospitals transfer patients to different rooms or when ambulances need to push patients into the operating room on bed frames, they often need to use medical equipment such as hospital bed trolleys, medical stretchers, or integrated hospital bed trolleys to assist in the transfer. At this time, there are often corridors, passageways, flower beds, and other areas without roofs or natural light between medical buildings. It is necessary to provide patients with a comfortable and safe moving environment. Baffles or umbrella-shaped structures are added to block the light, but they are inconvenient to store and prevent the sunlight from shining directly into the pupils or the bed frame from being affected by wind and rain.

[0003] Existing medical trolleys or hospital bed trolleys have no cover and only a single bed board for patients to lie flat. This means that during the trolley's movement, it will pass through corridors, passageways, flower beds, and other areas without roofs or natural light. While adding partitions or umbrella-like structures to provide shade is possible, they are inconvenient to store and still leave gaps. This allows sunlight to shine directly into the patient's eyes, causing dizziness or glare. Alternatively, the bed frame may be exposed to strong winds and rain, leading to secondary illnesses such as colds and flu, which can worsen the complexity of the patient's condition. When medical trolleys are not frequently used, the partitions or umbrella-like structures are prone to dust accumulation because they cannot be stored away and also take up considerable space, making them inconvenient to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a flatbed cart with a retractable shielding device. This solves the problem that existing medical flatbed carts or hospital bed trolleys provide patients with a single, uncovered bed board for lying down. This results in situations where the cart passes through corridors, passageways, flower beds, and other areas without roofs for light during the trolley's movement. While adding shields or umbrella-like structures can provide some protection, they are inconvenient to store and still leave gaps, allowing sunlight to shine directly into the patient's eyes, causing dizziness or glare. Additionally, the bed frame may be exposed to strong winds and rain, leading to secondary illnesses such as colds and exacerbating the complexity of the patient's condition. Furthermore, when the medical flatbed cart's shields or umbrella-like structures are not frequently used, they are prone to dust accumulation and take up considerable space, causing inconvenience in use.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a flatbed cart with a retractable cover device, including a mattress board, a cover component, and a bed frame, wherein the mattress board is fixed inside the bed frame, the cover component is installed inside the bed frame, and the cover component and the bed frame are operable by flipping and adjusting.

[0006] The covering component includes an arc-shaped frame, inner pads, covering fabric, adjusting wheels, a stand, and a sleeping bag body. The arc-shaped frame and inner pads are nested together. There are four arc-shaped frames and four inner pads, which are respectively installed on the left and right sides of the stand. The sleeping bag body is supported by the arc-shaped frame and the stand to form a bag structure. The arc-shaped frame can be flipped and adjusted by adjusting wheels and the stand. The covering fabric is close to the top of the arc-shaped frame and the stand. The adjusting wheels and the bed frame can be flipped and adjusted.

[0007] With the patient lying on the mattress board, medical staff manually push the bed frame to move and transfer the patient. The curved frame and upright plate of the shielding component can be manually adjusted and flipped at the middle of the bed frame where the adjusting wheels connect. This allows the curved frame and upright plate to flip and pull the shielding fabric to open up for sun protection, while the sleeping bag body also opens up to cover the patient, providing a safe transport space for the patient and achieving the same effect of sun protection, rain protection, and wind protection as a medical trolley.

[0008] Preferably, the adjusting wheel is provided with a shaft, a gear disk, and a wheel sleeve. The shaft is inserted into the interior of the shaft of the gear disk and the wheel sleeve. The shaft and the gear disk are fitted with a clearance. The gear disk and the bed frame can be rotated for adjustment.

[0009] The shaft and the sleeve are connected by an insertion and fixing structure. The gear disk can engage the needle strip by rotating on the outer surface of the shaft, forming a zoned adjustment of the needle strip scale to cover the spread of the fabric surface.

[0010] Preferably, an IV stand is vertically inserted into the left rear side of the bed frame.

[0011] Preferably, the infusion stand is provided with a bottle hanging truss, telescopic rods, and impact beads. The bottom of the middle section of the bottle hanging truss is welded with a telescopic rod, and four telescopic rods are provided, which are nested together with three impact beads in an alternating manner.

[0012] The IV stand can be detached and stored inside the bed frame using a telescopic rod and a stopper. It can also be fitted with an arc-shaped frame and housed under a film cover for dust protection and storage.

[0013] Preferably, the bed frame includes a film surface, a rectangular frame, and needle strips. The film surface is fixed to the left side inside the rectangular frame. There are two needle strips, which are respectively attached to the front and rear sides of the rectangular frame. The needle strips and the gear disk can be adjusted by rotating scale limits.

[0014] The film surface forms a half-area border within the rectangular frame, providing a dustproof and covering effect. Furthermore, the gear disc and needle strip can rotate and mesh, allowing the needle strip scale to be adjusted in sections to control the spread of the covering fabric.

[0015] Preferably, the bed frame is fixed with support pillars at its four corners, and a handrail is installed between every two support pillars on the front and rear ends of the bed frame.

[0016] Preferably, the support mechanism includes a spring seat cap block, a slide rail groove, and a support body. The slide rail groove and the support body are an integral structure. The spring seat cap block is installed inside the slide rail groove. The handrail and the slide rail groove are fitted with a clearance fit. The spring seat cap block and the handrail are locked together at the top.

[0017] The handrail slides up to its highest position within the slide rail groove and is then locked in place by a spring seat cap. Similarly, the handrail slides down to its highest position within the slide rail groove and is locked in place by a spring seat cap. This achieves the effect of raising, lowering, storing, and facilitating the use of the handrail by the support mechanism. Furthermore, the curved top of the handrail supports the curved top surface of the sleeping bag, preserving breathing space and patient movement space.

[0018] Preferably, the lower part of the support mechanism is fixed with casters, and a bottom frame is welded around the bottom sides of the four support mechanisms.

[0019] This utility model provides a flatbed cart with a retractable shielding device, which has the following beneficial effects:

[0020] This type of flatbed cart with a retractable sunshade device integrates a mattress board within the bed frame with an arc-shaped frame and a sunshade fabric. The patient lies inside the sleeping bag, where the waterproof and sun-shading coatings on the fabric provide sun and rain protection. The waterproof coating also prevents wind from penetrating the mattress board. The bed frame's stitching and the gears of the adjusting wheels create an adjustable, retractable arc-shaped frame. This allows medical staff to easily lift the arc-shaped frame when the medical flatbed cart or hospital bed trolley passes through corridors, passageways, flowerbeds, or other areas without overhead lighting, enabling the patient to comfortably pass through these areas. This enhances the flexibility and convenience of the retractable and sunshade-integrated medical flatbed cart. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1-6 This utility model provides a flatbed cart with a retractable covering device, including a mattress board 1, a covering component 2, and a bed frame 4. The mattress board 1 is fixed inside the bed frame 4, and the covering component 2 is installed inside the bed frame 4. The covering component 2 and the bed frame 4 can be flipped and adjusted.

[0031] Because existing medical trolleys or hospital bed trolleys have no cover and only a single bed board for patients to lie flat, this means that during the trolley's movement, there will be corridors, passageways, flower beds, and other areas without roofs or natural light passing by between medical buildings. While adding baffles or umbrella-like structures to block the light is necessary, it is inconvenient to store them, and the light still cannot be completely blocked, leaving gaps that allow the sunlight to shine directly into the patient's eyes and pupils, causing glare and dizziness.

[0032] The covering component 2 includes an arc-shaped frame 21, inner gaskets 22, covering fabric 23, adjusting wheels 24, a support plate 25, and a sleeping bag body 26. The arc-shaped frame 21 and inner gaskets 22 are nested together. There are four arc-shaped frames 21 and four inner gaskets 22, which are respectively installed on the left and right sides of the support plate 25. The sleeping bag body 26 is stretched open by the arc-shaped frame 21 and the support plate 25 to form a bag structure. The arc-shaped frame 21 can be flipped and adjusted by adjusting wheels 24 and the support plate 25. The covering fabric 23 is close to the top of the arc-shaped frame 21 and the support plate 25. The adjusting wheels 24 and the bed frame 4 can be flipped and adjusted.

[0033] It should be noted that by having the patient lie on the mattress board 1, medical staff can manually push the bed frame 4 to move and transfer the patient. The curved frame 21 and the upright plate 25 of the shielding component 2 can be manually adjusted to flip at the middle section of the bed frame 4 where the adjusting wheel 24 connects. This allows the curved frame 21 and the upright plate 25 to flip and pull the shielding cloth 23 to open up for sunshade, and the sleeping bag body 26 to also open up and take shape to cover the patient, providing the patient with a safe transport space and achieving the effect of sunshade, rain protection and wind protection during the operation of the medical flatbed.

[0034] The adjusting wheel 24 is provided with a shaft 241, a gear disk 242, and a wheel sleeve 243. The shaft 241 is inserted into the shaft of the gear disk 242 and the wheel sleeve 243. The shaft 241 and the gear disk 242 are in clearance fit. The gear disk 242 and the bed frame 4 can be rotated and adjusted.

[0035] It should be noted that the shaft 241 and the wheel sleeve 243 are connected and fixed by an insertion. The gear disk 242 can rotate on the outer surface of the shaft 241 to engage the needle strip 43, so that the needle strip 43 can be divided into areas by the rotation angle of the gear disk 242 to adjust the sunshade spread of the shading fabric 23.

[0036] The bed frame 4 is provided with a film surface 41, a rectangular frame 42, and needle bars 43. The film surface 41 is fixed inside the rectangular frame 42 on the left side. There are two needle bars 43, which are respectively attached to the front and rear sides of the rectangular frame 42. The needle bars 43 and the gear disk 242 can be rotated and adjusted according to the scale limit.

[0037] It should be noted that the film surface 41 forms a dustproof covering effect within half of the rectangular frame 42, and the gear disk 242 and the needle strip 43 can be rotated and meshed, forming an effect where the needle strip 43 scale of the gear disk 242 rotates to adjust the sunshade spread of the covering fabric surface 23 in different areas.

[0038] The bed frame 4 is fixed with support pillars 5 at its four corners. A handrail 6 is installed between every two support pillars 5 on the front and rear ends of the bed frame 4. The support pillar 5 is provided with a spring seat cap 51, a slide rail groove 52, and a support pillar 53. The slide rail groove 52 and the support pillar 53 are an integral structure. The spring seat cap 51 is installed inside the slide rail groove 52. The handrail 6 and the slide rail groove 52 are fitted with a clearance fit. The spring seat cap 51 and the handrail 6 are locked together at the top.

[0039] It should be noted that the handrail 6 slides up to the highest position in the slide rail groove 52 and is locked in place by the spring seat cap block 51. The handrail 6 slides down to the highest position in the slide rail groove 52 and is locked in place by the spring seat cap block 51. This achieves the effect of lifting, storing and using the handrail 6 by the support mechanism 5. In addition, the top of the handrail 6 is curved, which can support the curved top surface of the sleeping bag body 26 to retain breathing space and patient activity space.

[0040] Working process: The mattress board 1 is combined with the arc-shaped frame 21 of the shielding component 2 and the shielding fabric 23 inside the bed frame 4. The patient lies in the sleeping bag body 26 and is protected from the sun and rain by the sunshade coating of the shielding fabric 23. Then, the pins 43 of the bed frame 4 and the gear disk 242 of the adjusting wheel 24 form the scale adjustment and locking effect of the arc-shaped frame 21 for flipping and storing. When the medical trolley or hospital bed trolley passes through corridors, passageways, flower beds and other areas without roofs and light when pushed into medical buildings, medical staff can lift the arc-shaped frame 21 in time to let the patient cover the sleeping bag body 26 and pass through the areas without roofs and light. This improves the flexibility and convenience of the medical trolley, which can be stored and shielded from the sun. It prevents the patient's eyes from direct sunlight, avoids glare and dizziness, and provides a cool feeling in the shaded area.

[0041] Example 2:

[0042] Please see Figures 1-6 This utility model provides a flatbed cart with a retractable covering device, including a mattress board 1, a covering component 2, and a bed frame 4. The mattress board 1 is fixed inside the bed frame 4, and the covering component 2 is installed inside the bed frame 4. The covering component 2 and the bed frame 4 can be flipped and adjusted.

[0043] Because existing medical trolleys or hospital bed trolleys provide patients with a flat, uncovered single-board bed, this results in the trolley passing through corridors, passageways, flower beds, and other areas without roofs or natural light during the trolley's movement. While adding partitions or umbrella-like structures to provide cover can be done, these are inconvenient to store and still leave gaps, allowing the bed frame to be exposed to strong winds and rain, which can cause patients to suffer from wind-colds, colds, and other secondary illnesses, thus increasing the complexity of their medical conditions.

[0044] The covering component 2 includes an arc-shaped frame 21, inner gaskets 22, covering fabric 23, adjusting wheels 24, a support plate 25, and a sleeping bag body 26. The arc-shaped frame 21 and inner gaskets 22 are nested together. There are four arc-shaped frames 21 and four inner gaskets 22, which are respectively installed on the left and right sides of the support plate 25. The sleeping bag body 26 is stretched open by the arc-shaped frame 21 and the support plate 25 to form a bag structure. The arc-shaped frame 21 can be flipped and adjusted by adjusting wheels 24 and the support plate 25. The covering fabric 23 is close to the top of the arc-shaped frame 21 and the support plate 25. The adjusting wheels 24 and the bed frame 4 can be flipped and adjusted.

[0045] It should be noted that by having the patient lie on the mattress board 1, medical staff can manually push the bed frame 4 to move and transfer the patient. The curved frame 21 and the upright plate 25 of the shielding component 2 can be manually adjusted to flip at the middle section of the bed frame 4 where the adjusting wheel 24 connects. This allows the curved frame 21 and the upright plate 25 to flip and pull the shielding cloth 23 to open up for sunshade, and the sleeping bag body 26 to also open up and take shape to cover the patient, providing the patient with a safe transport space and achieving the effect of sunshade, rain protection and wind protection during the operation of the medical flatbed.

[0046] The adjusting wheel 24 is provided with a shaft 241, a gear disk 242, and a wheel sleeve 243. The shaft 241 is inserted into the shaft of the gear disk 242 and the wheel sleeve 243. The shaft 241 and the gear disk 242 are in clearance fit. The gear disk 242 and the bed frame 4 can be rotated and adjusted.

[0047] It should be noted that the shaft 241 and the wheel sleeve 243 are connected and fixed by an insertion. The gear disk 242 can rotate on the outer surface of the shaft 241 to engage the needle strip 43, so that the needle strip 43 can be divided into areas by the rotation angle of the gear disk 242 to adjust the wind and rain protection of the fabric surface 23.

[0048] The bed frame 4 is provided with a film surface 41, a rectangular frame 42, and needle bars 43. The film surface 41 is fixed inside the rectangular frame 42 on the left side. There are two needle bars 43, which are respectively attached to the front and rear sides of the rectangular frame 42. The needle bars 43 and the gear disk 242 can be rotated and adjusted according to the scale limit.

[0049] It should be noted that the film surface 41 forms a dustproof covering effect within the rectangular frame 42, creating a half-area border. Furthermore, the gear disk 242 and the needle strip 43 can rotate and mesh, allowing the needle strip 43 to be adjusted in sections by rotating the gear disk 242 to create an effect that allows the covering fabric surface 23 to be opened to block wind and rain.

[0050] The bed frame 4 is fixed with support pillars 5 at its four corners. A handrail 6 is installed between every two support pillars 5 on the front and rear ends of the bed frame 4. The support pillar 5 is provided with a spring seat cap 51, a slide rail groove 52, and a support pillar 53. The slide rail groove 52 and the support pillar 53 are an integral structure. The spring seat cap 51 is installed inside the slide rail groove 52. The handrail 6 and the slide rail groove 52 are fitted with a clearance fit. The spring seat cap 51 and the handrail 6 are locked together at the top.

[0051] It should be noted that the handrail 6 slides up to the highest position in the slide rail groove 52 and is locked in place by the spring seat cap block 51. The handrail 6 slides down to the highest position in the slide rail groove 52 and is locked in place by the spring seat cap block 51. This achieves the effect of raising, lowering, storing and using the handrail 6 by the support mechanism 5. In addition, the top of the handrail 6 is curved, which can support the curved top surface of the sleeping bag body 26 to retain breathing space and patient activity space.

[0052] Working process: The mattress board 1 is combined with the curved frame 21 of the covering component 2 and the covering fabric 23 inside the bed frame 4. The patient lies in the sleeping bag body 26 and is protected from rain by the waterproof coating of the covering fabric 23. The waterproof coating itself prevents wind from blowing into the mattress board 1. Then, the pins 43 of the bed frame 4 and the gear disk 242 of the adjusting wheel 24 form the scale adjustment and locking effect of the curved frame 21 for flipping and storing. When the medical trolley or hospital bed trolley passes through corridors, passageways, flower beds and other areas without roofs and light when pushed into medical buildings, medical staff can lift the curved frame 21 in time to let the patient cover the sleeping bag body 26 and pass through the areas without roofs and light. This improves the flexibility and convenience of the medical trolley, which can be stored, covered and protected from wind and rain, so that the patient does not feel damp or windy and is able to be transported with dry and comfortable clothing.

[0053] Example 3:

[0054] Please see Figures 1-6 This utility model provides a flatbed cart with a retractable covering device, including a mattress board 1, a covering component 2, and a bed frame 4. The mattress board 1 is fixed inside the bed frame 4, and the covering component 2 is installed inside the bed frame 4. The covering component 2 and the bed frame 4 can be flipped and adjusted.

[0055] Because existing medical trolleys or hospital bed trolleys have no cover and only a single bed board for patients to lie flat, this means that during the trolley's movement, it will pass through corridors, passageways, flower beds, and other areas without roofs or natural light. While adding partitions or umbrella-shaped structures to provide cover can be done, they are inconvenient to store. When the partitions or umbrella-shaped structures of the medical trolley are not frequently used, they are easy to collect dust because they cannot be stored, and they also take up a lot of space, making them inconvenient to use. Furthermore, the hospital bed trolley is subject to a certain amount of airborne dust, and if it is not cleaned regularly, it will lead to bacterial growth.

[0056] The covering component 2 includes an arc-shaped frame 21, inner gaskets 22, covering fabric 23, adjusting wheels 24, a support plate 25, and a sleeping bag body 26. The arc-shaped frame 21 and inner gaskets 22 are nested together. There are four arc-shaped frames 21 and four inner gaskets 22, which are respectively installed on the left and right sides of the support plate 25. The sleeping bag body 26 is stretched open by the arc-shaped frame 21 and the support plate 25 to form a bag structure. The arc-shaped frame 21 can be flipped and adjusted by adjusting wheels 24 and the support plate 25. The covering fabric 23 is close to the top of the arc-shaped frame 21 and the support plate 25. The adjusting wheels 24 and the bed frame 4 can be flipped and adjusted.

[0057] It should be noted that by having the patient lie on the mattress board 1, medical staff can manually push the bed frame 4 to move and transfer the patient. The curved frame 21 and the upright plate 25 of the shielding component 2 can be manually adjusted to flip at the middle section of the bed frame 4 where the adjusting wheel 24 connects. This allows the curved frame 21 and the upright plate 25 to flip and pull the shielding cloth 23 to open up for sunshade, and the sleeping bag body 26 to also open up and take shape to cover the patient, providing the patient with a safe transport space and achieving the effect of sunshade, rain protection and wind protection during the operation of the medical flatbed.

[0058] The adjusting wheel 24 is provided with a shaft 241, a gear disk 242, and a wheel sleeve 243. The shaft 241 is inserted into the shaft of the gear disk 242 and the wheel sleeve 243. The shaft 241 and the gear disk 242 are in clearance fit. The gear disk 242 and the bed frame 4 can be rotated and adjusted.

[0059] It should be noted that the shaft 241 and the wheel sleeve 243 are connected and fixed by an insertion. The gear disk 242 can rotate on the outer surface of the shaft 241 to engage the needle strip 43. This allows the needle strip 43 to be rotated at different angles, and the shielding cloth 23 can be adjusted in different areas to create an effect that allows the shielding cloth 23 to spread out. The shielding cloth 23 can also block pollen or dust particles in the air, thus ensuring the safety of patient transport operations.

[0060] An IV stand 3 is vertically inserted into the left rear side of the bed frame 4. The IV stand 3 is equipped with a bottle hanging truss 31, a telescopic rod 32, and a ramming ball 33. The bottom of the middle section of the bottle hanging truss 31 is welded with a telescopic rod 32. There are four telescopic rods 32 and three ramming balls 33, which are nested together in an alternating manner.

[0061] It should be noted that the infusion stand 3 can be detached and stored inside the bed frame 4 by means of the telescopic rod 32 and the impact ball 33, and can be adapted to be built into the curved frame 21 together under the cover of the film surface 41 for dustproof and covered storage.

[0062] The bed frame 4 is provided with a film surface 41, a rectangular frame 42, and needle bars 43. The film surface 41 is fixed inside the rectangular frame 42 on the left side. There are two needle bars 43, which are respectively attached to the front and rear sides of the rectangular frame 42. The needle bars 43 and the gear disk 242 can be rotated and adjusted according to the scale limit.

[0063] It should be noted that the film surface 41 forms a dustproof covering effect within half of the rectangular frame 42, and the gear disk 242 and the needle strip 43 can be rotated and engaged, forming an effect where the needle strip 43 scale is adjusted in sections to cover the spread of the covering fabric surface 23 by rotating the gear disk 242.

[0064] Working process: The mattress board 1 is combined with the arc-shaped frame 21 of the shielding component 2 and the shielding cloth 23 inside the bed frame 4, allowing the patient to lie in the sleeping bag body 26 and benefit from the dustproof effect of the shielding cloth 23. Then, the pins 43 of the bed frame 4 and the gear disk 242 of the adjusting wheel 24 form the scale adjustment and locking effect of the arc-shaped frame 21 for flipping and storing. When the medical trolley or hospital bed trolley passes through corridors, passageways, flower beds and other areas without roof lighting between medical buildings, medical staff can promptly lift the arc-shaped frame 21 to allow the patient to be covered in the sleeping bag body 26 and pass through the areas without roof lighting. This improves the flexibility and convenience of the medical trolley in storing the dustproof IV stand 3 and shielding component 2 through the film surface 41, ensuring the ease of dust-free storage after alcohol disinfection spraying of the medical trolley after patient transfer, and improving the convenience of the medical trolley for direct use without wiping dust during secondary transfer.

[0065] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
