Description

Technical Field

[0001] This utility model relates to the field of transport equipment technology, specifically an emergency surgical transport bed with lifting function. Background Technology

[0002] A patient transport bed is a specialized medical bed used for transferring patients between beds, from the operating table to the ward, and from the ambulance. It can improve the efficiency and safety of patient transfers while reducing the workload of nursing staff.

[0003] Chinese patent CN222091989U discloses a transfer bed for emergency surgery with lifting function. It includes a bed frame, a support plate, a support member, and a buffer mechanism. The support plate is movable relative to the ground. The support member is telescopically positioned between the bed frame and the support plate. The buffer mechanism is located at the bottom of the bed frame. The buffer mechanism has a connector and a first elastic unit. The connector is hinged to the bottom of the bed frame, and its second end slides relative to the surface of the support plate in a first direction. The first elastic unit is positioned in the first direction. When the bed frame moves vertically, the elastic force of the first elastic unit acts on the connector to create resistance to the vertical movement of the bed frame, reducing the vertical movement and preventing secondary injury to the patient during transport.

[0004] The aforementioned transport bed serves to prevent secondary injury to patients. However, while raising the transport bed, the existing technology also reduces its stability. Furthermore, during patient transport, the large size of the transport bed makes docking with vehicles and hospital beds difficult, resulting in low efficiency and affecting the optimal time for patient care. Therefore, there is a need for an emergency surgical transport bed with lifting and lowering functions. Utility Model Content

[0005] The purpose of this invention is to provide an emergency surgical transport bed with lifting function to solve the problems of poor stability of existing transport beds after being raised, and the difficulty in docking with vehicles and hospital beds, which leads to low efficiency in transferring patients.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an emergency surgical transport bed with lifting function, comprising a fixed base, wherein a lifting mechanism is provided on the lower side of the fixed base; the lifting mechanism comprises a connecting base, wherein two first fixed bases are fixedly installed side by side on the lower side of the fixed base and through the connecting base, and two second fixed bases are fixedly installed side by side on the lower side of the connecting base, and supports are rotatably installed at the four corners of the connecting base, a first roller is fixedly installed at one end of the support, and a first wheel frame is rotatably installed at the other end of the support, three second rollers are fixedly installed side by side on both sides of the first wheel frame, and a support rod is rotatably installed between the two first wheel frames, and a positioning handle is threaded through the two support rods, and two sliding grooves are provided side by side on the lower side of the fixed base.

[0007] Preferably, the first fixed base has two grooves arranged in parallel, and the second fixed base has two protrusions fixedly installed in parallel on one side, with the protrusions embedded in the grooves.

[0008] Preferably, the first roller is embedded in the groove, and the positioning handle has two external threads with opposite thread directions.

[0009] Preferably, a sliding mechanism is provided on the upper side of the fixed seat. The sliding mechanism includes two buckle plates, which are respectively fixedly installed on both sides of the fixed seat. A bed is slidably installed between the two buckle plates. Limit seats are fixedly installed on both sides of the bed. Two second wheel frames are fixedly installed side by side at one end of the bed. A third roller is fixedly installed on each of the two second wheel frames. A stop is slidably installed at one end of each of the two buckle plates. A traction spring is fixedly installed between the stop and the buckle plate.

[0010] Preferably, a strip groove is provided between the buckle plate and the fixing seat, the strip groove passes through one end of the buckle plate, and the limiting seat is embedded and slidably installed in the strip groove.

[0011] Preferably, the second wheel frame is composed of folding plates, and the third roller is located on the underside of the bed.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This emergency surgical transport bed with lifting function uses a control positioning handle to move two support rods in one direction. While the two support rods move, the support will rotate around the connecting seat. The first roller on it will move in the slide groove and support the fixed seat to move up or down, thereby changing the distance between the fixed seat and the ground. At the same time, the first wheel frame also moves with the support rods, which changes the spacing between the first wheel frames, thus achieving the effect of increasing the stability of the transport bed while raising its height.

[0014] 2) This emergency surgical transport bed with lifting function can be connected to a vehicle or hospital bed by controlling the movement of the bed body within two latches and coordinating with the height of the lifting fixed seat. At the same time, controlling the stop seat can release the restriction on the limit seat and realize the separation of the bed body from the fixed seat. A third roller is installed on the front side of the bed body, and the third roller is lower than the bed body, so that the bed body can be used independently. The bed body is small in size, which greatly increases the flexibility of the transport bed. Attached Figure Description

[0023] 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.

[0024] Example 1

[0025] Combination Figures 1-7 An emergency surgical transport bed with lifting function includes a fixed base 1, and a lifting mechanism 2 is provided on the lower side of the fixed base 1. The lifting mechanism 2 includes a connecting base 201. Two first fixed bases 202 are fixedly installed side by side on the lower side of the fixed base 1 and through the connecting base 201. Two second fixed bases 203 are fixedly installed side by side on the lower side of the connecting base 201. Supports 204 are rotatably installed at the four corners of the connecting base 201. A first roller 205 is fixedly installed at one end of the support 204, and a first wheel frame 206 is rotatably installed at the other end of the support 204. Three second rollers 207 are fixedly installed side by side on both sides of the first wheel frame 206. A support rod 208 is rotatably installed between the two first wheel frames 206. A positioning handle 209 is threaded through the two support rods 208. Two sliding grooves 210 are provided side by side on the lower side of the fixed base 1.

[0026] See Figure 3 and Figure 4 Furthermore, the first fixed seat 202 has two grooves arranged side by side, the second fixed seat 203 has two protrusions fixedly installed side by side on one side, and the protrusions are embedded in the grooves, the first roller 205 is embedded in the slide groove 210, and the positioning handle 209 has two external threads with opposite thread directions.

[0027] Specifically, by controlling the first fixed seat 202 and the second fixed seat 203 to be fastened and slidably connected, the fixed seat 1 and the connecting seat 201 are always in a parallel relationship. When the positioning handle 209 is rotated, the two external threads with opposite directions on the positioning handle 209 cause the two support rods 208 to move in opposite directions, thereby increasing or decreasing the distance between the two support rods 208. When the two support rods 208 move, the support 204 will rotate around the connecting seat 201 and cause the first roller 205 to move in the slide groove 210, thereby increasing or decreasing the distance between the fixed seat 1 and the ground. The other end of the support 204 is rotatably mounted with a first wheel frame 206, so that the first wheel frame 206 moves with the movement of the two support rods 208, thereby increasing the distance between the first wheel frames 206 when the fixed seat 1 is raised, ensuring the stability of the transfer bed.

[0028] Example 2

[0029] Combination Figure 1 , Figure 5 and Figure 6A sliding mechanism 3 is provided on the upper side of the fixed base 1. The sliding mechanism 3 includes two buckle plates 301. The two buckle plates 301 are fixedly installed on both sides of the fixed base 1, and a bed 302 is slidably installed between the two buckle plates 301. Limit seats 303 are fixedly installed on both sides of the bed 302, and two second wheel frames 304 are fixedly installed side by side at one end of the bed 302. A third roller 305 is fixedly installed on each of the two second wheel frames 304. A stop seat 306 is slidably installed at one end of each of the two buckle plates 301, and a traction spring 307 is fixedly installed between the stop seat 306 and the buckle plate 301.

[0030] See Figure 5 and Figure 6 Furthermore, based on Embodiment 1, a strip groove is provided between the buckle plate 301 and the fixed seat 1, the strip groove passes through one end of the buckle plate 301, and the limiting seat 303 is embedded and slidably installed in the strip groove. The second wheel frame 304 is composed of folding plates, and the third roller 305 is located on the lower side of the bed body 302.

[0031] Specifically, by installing limiting seats 303 on both sides of the bed body 302, the bed body 302 is slidably installed between two buckle plates 301 under the restriction of the limiting seats 303. One end of the buckle plate 301 is penetrated by a strip groove, and a stop 306 is slidably installed on one end of the buckle plate 301. A traction spring 307 is fixedly installed between the stop 306 and the buckle plate 301. In use, the restriction of the stop 306 on the limiting seat 303 can be released by pulling the stop 306. Further control of the movement of the bed body 302 can remove the bed body 302 from the buckle plate 301. A third roller 305 is installed on one end of the bed body 302, and the roller is supported by the second wheel frame 304 so that it is lower than the bed body 302, so that the bed body 302 can be used independently to facilitate the transfer of patients.

[0032] In actual operation, by controlling the first fixed seat 202 and the second fixed seat 203 to fasten and slide together, the fixed seat 1 and the connecting seat 201 are always in a parallel relationship. When the positioning handle 209 is rotated, the two external threads with opposite directions on the positioning handle 209 cause the two support rods 208 to move in opposite directions, thereby increasing or decreasing the distance between the two support rods 208. When the two support rods 208 move, the support 204 will rotate around the connecting seat 201 and cause the first roller 205 to move in the slide groove 210, thereby increasing or decreasing the distance between the fixed seat 1 and the ground. The other end of the support 204 is rotatably mounted with a first wheel frame 206, so that the first wheel frame 206 moves with the movement of the two support rods 208, thereby increasing the distance between the first wheel frames 206 when the fixed seat 1 is raised, ensuring the stability of the transfer bed.

[0033] By installing limiting seats 303 on both sides of the bed body 302, the bed body 302 is slidably installed between two buckle plates 301 under the restriction of the limiting seats 303. One end of the buckle plate 301 is penetrated by a strip groove, and a stop 306 is slidably installed on one end of the buckle plate 301. A traction spring 307 is fixedly installed between the stop 306 and the buckle plate 301. In use, the restriction of the stop 306 on the limiting seat 303 can be released by pulling the stop 306. Further control of the movement of the bed body 302 can remove the bed body 302 from the buckle plate 301. A third roller 305 is installed on one end of the bed body 302, and the roller is supported by the second wheel frame 304 so that it is lower than the bed body 302, so that the bed body 302 can be used independently to facilitate the transfer of patients.
