Description

Technical Field

[0001] The present invention relates to the technical field of transfer beds, and more specifically, to a transfer device for critically ill patients in medical care. Background Art

[0002] Bed transfer is a frequently performed item in medical treatment. For the transfer of critically ill patients, the conventional method of manual lifting not only has low transfer efficiency but also easily causes secondary injuries to patients. Therefore, the prior art uses a transfer device for critically ill patients in medical care, which realizes the stable transfer of patients through an electric control system and supports operations such as lifting, translation, and angle adjustment, and is applicable to high-demand scenarios such as operating rooms, ICUs, and orthopedics departments.

[0003] The existing transfer device for critically ill patients in medical care mainly includes a bed board, and a translation board that can slide laterally is arranged on the bed board. During use, the translation board extends to one side to lift the patient on the hospital bed, and then the translation board carries the patient from the hospital bed to the bed board. In order to reduce the risk of cross-infection and protect the safety of patients, a sterile sheet needs to be laid on the translation board. The prior art uses a cross beam installed on the bed board, the cross beam is located above the translation board, one side of the sterile sheet is manually fixed on the cross beam, and the other side of the sterile sheet is movably arranged under the translation board, showing a "giant" shape. Since one side of the sterile sheet above the translation board is fixed and the other side below the translation board is movable, when the translation board extends to one side, the sterile sheet below the translation board can be transferred to the upper side. During this process, the patient on the hospital bed is gradually transferred to the translation board covered with the sterile sheet.

[0004] Since the hospital bed is covered with a bedsheet, when the bedsheet is wet or the surface is rough, and the patient has a large body weight, the adhesion force and friction between the sterile sheet under the translation board and the bedsheet increase, resulting in difficulty in transferring the sterile sheet below to the upper side, and increasing the pulling force between the cross beam and the upper sterile sheet, resulting in the release of the fixation between the upper sterile sheet and the cross beam, or the upper sterile sheet being damaged by strong pulling, and it is necessary to re-transfer the patient to replace the new sterile sheet, which not only wastes time but also has an adverse impact on the patient. Summary of the Invention

Detailed Description of the Invention

[0029] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0030] Refer to the accompanying drawings of the specification Figures 1 to 8, A medical care intensive patient transfer device, including a vehicle chassis 1, a bed board frame 2 is installed on the vehicle chassis 1, headrest seats 3 are installed at both ends of the bed board frame 2, a bed board 4 is slidably installed on the bed board frame 2, and the bed board 4 is located between two groups of headrest seats 3. An annular belt 41 is provided on the outer periphery of the bed board 4. A driving mechanism 7 is installed between the bed board frame 2 and the bed board 4, and the driving mechanism 7 is used to drive the bed board 4 to slide horizontally. A cross beam seat 8 is installed on the headrest seat 3. The cross beam seat 8 includes an upper cover plate 81 and a lower mounting seat 82, and the upper cover plate 81 is detachably installed on the top of the lower mounting seat 82. A support plate 811 is fixedly installed inside the upper cover plate 81. A reel 812 is rotatably installed on the support plate 811, and the reel 812 is used to wind the sterile sheet 813. A shear block 821 is installed inside the lower mounting seat 82. A linear drive 822 is provided above the shear block 821. A cutting knife 823 is installed at the output end of the linear drive 822. The sterile sheet 813 is arranged between the shear block 821 and the cutting knife 823. An outlet is opened obliquely above the shear block 821 on the lower mounting seat 82. A clamping assembly 9 is installed at one end of the bed board 4, and the sterile sheet 813 unwound from the reel 812 is clamped by the clamping assembly 9.

[0031] It should be noted that the upper cover plate 81 and the lower mounting seat 82 are connected by screws and screw hole plates. A V-shaped shear groove is opened at the top of the shear block 821. The linear drive 822 is a linear cylinder, and the cutting knife 823 is a V-shaped blade. The V-shaped blade is adapted to the V-shaped shear groove. The driving mechanism 7 and the linear drive 822 adopt the existing remote control switch control technology.

[0032] In this embodiment, the implementation scenario is specifically as follows: Pull one side of the sterile sheet 813 to continuously unwind the reel 812, fix the pulled-out side of the sterile sheet 813 on the clamping assembly 9, start the driving mechanism 7 to drive the bed board 4 to move out to one side. At this time, the bed board 4 pulls the sterile sheet 813 to be laid on the upper surface of the bed board 4. Drive the cutting knife 823 to descend through the linear drive 822 to cut the sterile sheet 813. It should be noted that a reserved section is set for the extension of the bed board 4. After cutting the sterile sheet 813, the bed board 4 continues to move towards the reserved section to completely pull out the sterile sheet 813 located inside the lower mounting seat 82 after cutting. By directly laying the sterile sheet 813 above the bed board 4 as a whole, the sterile sheet 813 can be prevented from contacting the bed sheet, avoiding damage to the sterile sheet 813 due to strong pulling caused by the adhesion force and friction between the sterile sheet 813 and the bed sheet, thus ensuring the normal laying of the sterile sheet 813, saving the time for replacing the waste sterile sheet 813, and preventing adverse effects on the patient.

[0033] Furthermore, a guide plate 824 is fixedly provided above the inner side of the outlet corresponding to the lower mounting seat 82. A guide block 825 is installed inside the lower mounting seat 82. A conveying wheel is installed on the guide block 825, and two groups of conveying wheels are arranged corresponding to the upper and lower sides of the sterile sheet 813. The rotation directions of the two groups of conveying wheels are opposite.

[0034] It should be noted that the conveying wheel is driven by a micro motor, and the micro motor also adopts remote control switch control technology. The top of the shearing block 821 is an inclined surface, and the guide plate 824 is inclined. After the current section of the sterile sheet 813 is cut off, the subsequent section of the sterile sheet 813 is located inside the outlet and cannot be taken out. The two sets of conveying wheels drive the subsequent section of the sterile sheet 813 to move towards the outlet, and with the guidance of the guide plate 824, the subsequent section of the sterile sheet 813 is moved to the outside of the outlet.

[0035] Furthermore, a functional block 826 is installed inside the lower mounting base 82. An installation box 827 is provided on the side of the functional block 826 away from the guiding block 825. A disinfection lamp and a heating lamp are installed inside the functional block 826.

[0036] It should be noted that the disinfection lamp and the heating lamp inside the functional block 826 also adopt remote control switch control technology. The installation box 827 is used to install the power supply and the controller, which supplies power and controls the disinfection lamp, the heating lamp, the micro motor and the linear driver 822. According to requirements, the disinfection lamp and the heating lamp are turned on to disinfect and heat the sterile sheet 813 to ensure the sterility and dryness of the sterile sheet 813.

[0037] Furthermore, a support wheel seat 42 is installed on the bedplate frame 2. A support wheel 421 is rotatably installed on the support wheel seat 42. The support wheel 421 is provided at the bottom of the bedplate 4. The clamping assembly 9 includes a top block 91 and a clamping block 92, and the clamping block 92 is located on one side of the top block 91. An elastic member 911 is connected between the top block 91 and the clamping block 92. A second connecting shaft 912 is fixedly provided on the side of the top block 91 close to the clamping block 92. A first clamping wheel 913 is rotatably provided at the end of the second connecting shaft 912 away from the top block 91. The clamping block 92 is fixedly provided at one end of the bedplate 4. A clamping groove 921 is formed inside the top block 91, and a second clamping wheel 93 is rotatably installed inside the clamping groove 921.

[0038] It should be noted that one side of the top block 91 away from the clamping block 92 is an arc surface, and the height of the top block 91 is less than the height of the bed board 4. The lengths of the crossbeam seat 8 and the clamping assembly 9 are less than the length of the bed board 4. A buffer section is reserved between the top block 91 and the clamping block 92. One side of the sterile sheet 813 is clamped into the interior of the clamping groove 921 and is located between the first clamping wheel 913 and the second clamping wheel 93. The sterile sheet 813 is clamped by the elastic extrusion of the elastic member 911. During the process of extending the bed board 4 under the patient, the top block 91, as the front end, is pushed backward towards the clamping block 92, thereby compressing the buffer section and making the first clamping wheel 913 move closer to the second clamping wheel 93 to enhance the clamping effect. When the patient is transferred back to the hospital bed from the bed board 4, the bed board 4 is moved out from under the patient. At this time, the top block 91, as the rear end, is pushed away from the clamping block 92, thereby expanding the buffer section and making the first clamping wheel 913 move away from the second clamping wheel 93, releasing the clamping of the sterile sheet 813, facilitating the removal of one side of the sterile sheet 813 from the interior of the clamping groove 921. The side of the sterile sheet 813 can be automatically detached from the clamping groove 921 by the friction between the patient's clothes and the sterile sheet 813, or the top block 91 can be manually pulled before the bed board 4 is retracted to remove the sterile sheet 813 from the clamping groove 921.

[0039] Furthermore, a soft rubber sleeve 914 is sleeved on the outer periphery of the first clamping wheel 913. One end of the second clamping wheel 93 is fixedly provided with a limiting wheel 931. A limiting piece 932 is fixedly provided inside the clamping block 92. Protrusions are provided on the outer periphery of the limiting wheel 931, and both sides of the protrusions are a straight surface and an arc surface respectively. Clamping teeth 933 are fixedly provided on the outer periphery of the second clamping wheel 93.

[0040] It should be noted that, with reference to the Figure 8 viewpoint, when the second clamping wheel 93 rotates clockwise, the limiting piece 932 slides closely along the arc surface of the limiting wheel 931. When the second clamping wheel 93 rotates counterclockwise, one end of the limiting piece 932 abuts against the straight surface of the limiting wheel 931 for braking. The clamping teeth 933 can indent the soft rubber sleeve 914 to provide stable clamping. When releasing the clamping, a distance is left between the clamping teeth 933 and the soft rubber sleeve 914, and it is not necessary for the second clamping wheel 93 to rotate counterclockwise.

[0041] Furthermore, a roller track 32 is installed on the headstock 3. An opening 34 and a guiding groove 35 are formed on the headstock 3, and the guiding groove 35 is located below the opening 34. One end of the first connecting shaft 73 is installed with a roller, and the roller rolls along the upper side of the roller track 32. One side of the driving mechanism 7 is fixedly provided with a guiding column, and the guiding column slides along the interior of the guiding groove 35. A rack plate 36 is installed on the headstock 3. A slider 83 is installed at the bottom of the crossbeam seat 8, and the slider 83 is slidably arranged along the rack plate 36.

[0042] It should be noted that transmission teeth are provided below the rack plate 36, and the external gear 722 is meshed with the transmission teeth of the rack plate 36.

[0043] Further, side plates 5 are rotatably connected to both sides of the bed board frame 2, a handle 6 is installed on the headstock 3, wheels 13 are installed on the chassis 1, the output end of the driving mechanism 7 is drivingly connected to a transmission gear set 72, the transmission gear set 72 includes an internal gear 721, an external gear 722 is provided on one side of the internal gear 721, a first connecting shaft 73 penetrates through the centers of the internal gear 721 and the external gear 722, and the first connecting shaft 73 drives the internal gear 721 and the external gear 722 to rotate synchronously. A transmission assembly 71 is provided at one end of the bed board 4 away from the driving mechanism 7, and the driving mechanism 7 has the same structure as the transmission assembly 71.

[0044] It should be noted that the side plate 5 is hinged and fixed by a buckle. The side plate 5, the handle 6 and the driving mechanism 7 are all prior arts, and the whole can be moved through the handle 6 and the wheels 13.

[0045] In the above embodiment, the whole can transfer the patient from the hospital bed to the bed board 4, then from the bed board 4 to the operating room, and finally transfer the patient back to the hospital bed. During this process, the heights of the hospital bed and the operating table in the operating room are different, and there are many medical devices around the operating table, making it inconvenient to observe the adjusted height of the bed board frame 2, and it is easy to generate an excessive height difference between the bed board frame 2 and the operating table, thus affecting the extension of the bed board 4. To solve this problem, the following technical solutions are also provided:

[0046] Refer to the attached drawings of the specification Figure 3 and Figure 9 , a battery holder 11 is installed on the chassis 1, a lifting assembly 12 is installed between the chassis 1 and the bed board frame 2, and the lifting assembly 12 is used to drive the bed board frame 2 to move up and down. Sleeve one 31 and sleeve two 33 are respectively installed at both ends of the headstock 3, and a height calibration assembly 21 is installed on the sleeve one 31.

[0047] It should be noted that the sleeve one 31 is arranged on the side close to the hospital bed, and the sleeve two 33 is used to support the suspension rod.

[0048] Further, the height calibration assembly 21 includes a calibration shaft 211, and the calibration shaft 211 is located inside the sleeve one 31. A connecting sleeve 213 is rotatably connected to the top of the calibration shaft 211, and the connecting sleeve 213 is fixedly arranged at one end of the height calibration assembly 21.

[0049] It should be noted that the calibration shaft 211 is slidably arranged inside the sleeve one 31.

[0050] Still further, a detection rod 214 is installed at the bottom end of the calibration shaft 211, a pressure sensor 215 is installed inside the sleeve one 31, the detection rod 214 is fixed to the detection end of the pressure sensor 215, and a warning lamp 216 is installed at the bottom end of the pressure sensor 215.

[0051] It should be noted that the pressure sensor 215 and the warning light 216 are existing mature technologies. The specific connection circuit is familiar to those skilled in the art. The pressure sensor 215 and the warning light 216 are connected to the same power supply and switch, that is, when the pressure sensor 215 is activated, the warning light 216 needs to be activated.

[0052] In this embodiment, the implementation scenario is specifically as follows: In the low version, the detection rod 214, the pressure sensor 215 and the warning light 216 are not installed. The lifting assembly 12 drives the bedplate frame 2 to rise and be higher than the height of the operating table. The vehicle chassis 1 is moved close to the operating table, and the calibration plate 212 is rotated above one end of the operating table. Then the bedplate frame 2 is lowered. By observing the height change of the calibration plate 212, the adjusted height of the bedplate frame 2 can be visually obtained. In the high version, the detection rod 214, the pressure sensor 215 and the warning light 216 are installed. When the calibration plate 212 moves upward, the pressure sensor 215 is pulled by the detection rod 214, so that the pressure sensor 215 detects a pressure change. By setting the normal detection range of the pressure sensor 215, when the pressure detection of the pressure sensor 215 enters the normal detection range, the warning light 216 can be activated to emit a light warning, that is, when the warning light 216 is on, it means that the height adjustment of the bedplate frame 2 is in place. It is applicable to the operating table with more peripheral medical devices, which is convenient for observing the adjusted height of the bedplate frame 2 and avoiding excessive height difference between the bedplate frame 2 and the operating table.

[0053] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
