DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figure 1-Figure 9As shown, the present embodiment provides an intelligent physiological parameter real-time monitoring medical transfer bed, including a transfer vehicle 3, a bed frame 2 is fixedly connected to the top of the transfer vehicle 3, a transmission mechanism is arranged in the bed frame 2, the top surface of the bed frame 2 is connected to a transfer bed body 1 through the transmission mechanism, the transfer bed body 1 includes a bed board 110, a driving mechanism is arranged on one side of the bed board 110, the driving mechanism includes a driving part fixedly connected to the transfer bed body 1, a guide roller 111 is installed on the side of the transfer bed body 1 away from the driving part, a transfer belt 112 is arranged between the driving part and the guide roller 111, and a monitoring mechanism 4 is arranged on the side of the bed frame 2 close to the driving part.

[0027] The height of the bed frame 2 can be adjusted by the transfer vehicle 3. The present invention can realize the transfer of patients from "bed to transfer bed" and "transfer bed to target position". The patient can maintain a relatively comfortable lying state during the transfer process. The transfer process is completed by the transfer bed, reducing the pain and worsening of the condition caused by changes in posture during manual transfer.

[0028] A further optimized solution is that the driving part includes a main fixed seat 107 and a secondary fixed seat 102 fixedly connected to one side of the transfer bed 1, and an active roller 105 and a supporting roller 103 are rotatably connected between the main fixed seat 107 and the secondary fixed seat 102 respectively. A transfer belt 112 is provided on the outer sides of the active roller 105, the supporting roller 103 and the guide roller 111, and a rotating motor 108 is fixedly connected to the inner side of the main fixed seat 107, and a rotating gear 109 is installed on the output shaft of the rotating motor 108 and the side of the active roller 105 close to the rotating motor 108 respectively, and the two rotating gears 109 are located on the outer side of the main fixed seat 107 and mesh with each other.

[0029] A further optimized solution is that a transmission shaft 104 is rotatably connected between the main fixed seat 107 and the auxiliary fixed seat 102, and translation gears 101 are respectively installed on both sides of the transmission shaft 104. The two translation gears 101 are respectively located on the outside of the main fixed seat 107 and the auxiliary fixed seat 102, and a translation motor 106 is fixedly connected to the inner side of the main fixed seat 107. The output shaft of the translation motor 106 passes through the main fixed seat 107 and is fixedly connected to the translation gear 101, and the two adjacent translation gears 101 are meshed with each other.

[0030] When the transport bed 1 needs to be displaced along the X direction, the transport bed 1 can be controlled to be displaced by selecting the displacement direction through the control handle 43.

[0031] The patient cannot be completely moved in or out by simply moving the transport bed 1 along the X direction, and the patient needs to be moved in or out with the help of the transfer belt 112. When the patient needs to be moved into the transport bed, the transport bed 1 needs to be controlled to move under the patient first. When the guide roller 111 contacts the patient's body, the rotary motor 108 starts to operate, causing the transfer belt 112 to rotate in the opposite direction, ensuring that the bed plate 110 and the transfer belt 112 remain relatively still with the patient during the process of moving under the patient. When the bed plate 110 and the transfer belt 112 move to a certain position under the patient, the translation motor 106 stops operating. Subsequently, the patient moves to the middle position of the transport bed 1 along the transfer belt 112 under the action of the rotary motor 108, and the rotary motor 108 stops operating. The translation motor 106 controls the transport bed 1 to move in the negative X direction until the transport bed 1 returns to the initial position. At this point, the patient is transferred from the position to be transferred to the transport bed.

[0032] When the patient is transferred from the transfer bed to the target position, the translation motor 106 controls the transfer bed body 1 to move in the positive X direction, and stops moving when the bed plate 110 is partially located at the target position. Subsequently, the rotation motor 108 starts to operate, and the patient is moved out of the transfer bed under the action of the transfer belt 112. At the same time, the translation motor 106 controls the transfer bed body 1 to move in the negative X direction until the patient is moved out to the target position.

[0033] Considering the comfort of the patient, the bed board 110 is made of a relatively soft plastic material. The bed board 110 is supported by two linear guide rails 21 and a support roller assembly 22 at both ends along the Y direction, and is supported by multiple groups of support guide rollers 111 and support rollers 103 along the X direction. The support roller assembly 22 is mainly composed of a U-shaped bracket 221, a bearing wheel 222, a rolling shaft, and a pressure strip 224. The bearing roller can roll freely along its axial direction, thereby playing a supporting role in the translation process of the transport bed body 1, while minimizing friction resistance.

[0034] According to a further optimized solution, the transmission mechanism includes a mounting base 205 fixedly connected to the bed frame 2, and linear guide rails 21 are symmetrically provided at both ends of the bed frame 2, the slider of the linear guide rail 21 is fixedly connected to the transfer bed 1, and the slide rail of the linear guide rail 21 is fixedly connected to the mounting base 205.

[0035] A further optimized solution is that a mounting base 205 is fixedly connected inside the bed frame 2, a rack adjustment seat 202 is mounted on one end of the mounting base 205, an adjusting pin 203 is mounted on one side of the rack adjustment seat 202, an adjusting rack 201 is mounted on the end of the adjusting pin 203 away from the rack adjustment seat 202, a fixed rack 204 is mounted on the other end of the bed frame 2, a translation gear 101 close to the adjusting rack 201 is meshed with the adjusting rack 201, and a translation gear 101 close to the fixed rack 204 is meshed with the fixed rack 204.

[0036] A further optimized solution is that a plurality of groups of supporting roller assemblies 22 are evenly spaced at one end of the mounting base 205 away from the driving portion, the supporting roller assembly 22 comprises a U-shaped bracket 221 fixedly connected to the mounting base 205, a plurality of rolling shafts are evenly spacedly installed in the U-shaped bracket 221, bearing wheels 222 are provided on the rolling shafts, and a pressure strip 224 is provided at the bottom of the U-shaped bracket 221.

[0037] The transfer bed 1 can be displaced in the X direction by the translation gears 101 and racks at both ends of the transfer bed 1 under the action of the translation motor 106. When assembling the translation gears 101 and racks at both ends of the transfer bed 1, position adaptation adjustment is required. The adjustment method is:

[0038] The adjusting rack 201 is connected to the mounting base 205 through a waist-shaped hole, the rack adjusting base 202 is fixedly connected to the mounting base 205, the adjusting pin 203 is threadedly connected to the cross section of the adjusting rack 201, and the position of the adjusting rack 201 is fine-tuned by rotating the adjusting pin 203 with the fixed rack 204 as a reference, so that the translation gears 101 at both ends are perfectly meshed with the rack.

[0039] One end of the bed board 110 is supported by multiple groups of supporting roller assemblies 22, and the other end is supported by a supporting drum 103, thereby enhancing the supporting strength of the bed board 110. The bed board 110 can be made of a material with a certain degree of flexibility.

[0040] A further optimized solution is that the transfer vehicle 3 includes a vehicle body, electric push rods 31 are respectively installed at the four corners of the top surface of the vehicle body, the top surface of the electric push rods 31 is fixedly connected to the bed frame 2, silent wheels 33 are respectively installed at the four corners of the ground of the vehicle body, and an electric control box 32 and a storage box 34 are respectively provided on the top surface of the vehicle body.

[0041] Taking into account that the patient's position is not necessarily flush with the transfer bed, the transfer vehicle 3 is provided with 4 sets of electric push rods 31. The height of the electric push rods 31 can be adjusted according to actual needs to make the transfer bed flush with the patient's position, thereby facilitating the transfer of the patient.

[0042] The transport vehicle 3 is also provided with a storage box 34 , in which the patient's personal belongings or other items can be placed during the patient transport process, thereby facilitating the medical staff or family members to transport the patient.

[0043] Further optimizing the scheme, the monitoring mechanism 4 includes a monitoring bracelet 41, a display screen 42 and a control handle 43 arranged on one side of the bed frame 2. During the patient transfer process, the patient wears the monitoring bracelet 41, and the patient's physiological parameters are displayed on the display screen 42 in real time, so that the doctor can understand the patient's physiological parameters at any time.

[0044] The work of the transfer bed includes the following steps:

[0045] 1) Pushing the transport vehicle 3 to transfer the transport vehicle 3 to the patient's location;

[0046] 2) Adjust the height of the bed frame 2 so that the transport bed body 1 is flush with the patient transfer plane;

[0047] 3) Select the control mode (moving-in mode, moving-out mode) by controlling the handle 43;

[0048] 4) By controlling the handle 43, the transport bed 1 is controlled to move in the negative direction X, and the bed returns to the standby state;

[0049] 5) Transfer completed.

[0050] The transfer bed has two working modes:

[0051] (1) Migration mode: mainly divided into two steps.

[0052] Step 1: Control the transfer bed 1 to move in the positive direction X by controlling the handle 43 until half of the patient's body is placed on the bed board 110 .

[0053] Step 2: Control the rotating motor 108, which drives the rotating gear 109 group to rotate, and the transfer belt 112 wound on the active roller 105 is displaced, so that the patient is transferred to the middle position of the transfer bed 1 under the action of the transfer belt 112.

[0054] (2) Removal mode: mainly divided into two steps.

[0055] Step 1: By controlling the handle 43, the transport bed 1 is controlled to move in the positive direction X so that the patient is located above the bed.

[0056] Step 2: Control the rotating motor 108, which drives the rotating gear 109 to rotate, causing the transfer belt 112 wrapped around the active roller 105 to move. Finally, the patient is moved out by the transfer belt 112, and the transfer bed 1 moves in the negative direction of X, and finally the patient is transferred to the target position.
