Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a transfer bed for tumor radiotherapy. Background Art

[0002] During radiation oncology (RT), a transfer couch (sometimes called a patient positioning couch or treatment couch) is a specialized bed used to safely and precisely move patients from the reception area to the RT equipment (such as a linear accelerator) and to ensure they remain stable and precisely positioned during treatment.

[0003] For example, a Chinese patent with the patent number CN213489887U discloses an oncology rescue transport vehicle that can move patients into the ambulance without the need for multiple people to lift them. This operation process is also applicable to the operation of sending patients to an examination table with a higher operating surface.

[0004] Although the above-mentioned cited documents can achieve the elevation of patients in actual use, they still rely on manual adjustment in actual use. Not only is the adjustment slow and easily affects the treatment of the disease, but it also consumes a lot of labor overall and is not practical in actual transportation. In addition, the tumor transfer bed lacks effective buffering and transportation during use. During the transportation process, the transfer bed lacks a buffering device and cannot effectively absorb the vibration and impact caused by uneven ground or movement, which may cause discomfort to the patient and increase anxiety and tension before treatment. At the same time, it is difficult for the bed to achieve rapid transfer of patients between different beds. During the transfer, the patient still needs to get out of bed and get back on bed, making the overall transportation cumbersome.

[0005] Therefore, a transfer bed for tumor radiotherapy is provided to solve the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the existing technology, the purpose of the present invention is to provide a transfer bed for tumor radiotherapy, which effectively cushions the shock of the transfer bed by setting a buffer structure, thereby greatly improving the comfort of tumor radiotherapy patients during transportation, and at the same time utilizes a heavy-duty electric push rod to achieve smooth lifting of the transfer bed.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: A transfer bed for tumor radiotherapy, comprising a horizontally arranged main support base; The upper end surface of the main support base is equipped with a plurality of bed body shock absorbing mechanisms along its transverse direction; A transfer bed board is commonly installed above the plurality of groups of bed body cushioning mechanisms; Two slide rails are provided above the transfer bed board; Several sets of heavy-duty push rod motors are installed on both sides above the main support base, and the output ends of the several sets of heavy-duty push rod motors are vertically arranged and extended to be connected to the bottom of the transfer bed board; The bed shock-absorbing mechanism includes four bottom plates arranged in a rectangular shape above the main support base, each of which is provided with a lower buffer cylinder above the four bottom plates, each of which is a hollow cylinder filled with buffer foam; an upper buffer cylinder is sleeved on the outside of the four lower buffer cylinders, and a base is commonly supported above the four upper buffer cylinders; An oil pressure buffer is supported and arranged at the center of the upper end surface of the base, a positioning seat is installed on the upper end surface of the oil pressure buffer, and a connecting tube is assembled on the upper end surface of the positioning seat, and the connecting tube is connected to the bottom of the bed plate of the transfer bed.

[0008] Furthermore, the bottom of the upper buffer cylinder fits with the top of the buffer foam; ear seats are protruding on both sides of the positioning seat, and two connecting seats are provided on both sides of the two ear seats and the base. A hydraulic buffer is installed between the two connecting seats on the same side and adjacent to each other up and down, and the four hydraulic buffers are installed in an inclined shape on the side of the positioning seat and the base.

[0009] Furthermore, side beams are integrally provided on both sides of the main support base, sleeves are integrally provided at both ends of the two side beams, a plug-in wheel sleeve is assembled in each sleeve, and a locking bolt is threadedly connected to the side of each sleeve.

[0010] Furthermore, the plug-in rod type wheel sleeve includes an insertion rod and a movable wheel, the insertion rod is arranged above the plug-in rod type wheel sleeve and inserted in the sleeve, the end of the locking bolt passes through the sleeve and extends to abut against the side wall of the insertion rod; the movable wheel is rotatably arranged in the plug-in rod type wheel sleeve.

[0011] Furthermore, a side panel is provided on one side of the transfer bed bed board; a side panel is provided on one side of the transfer bed bed board; a mattress is supported above the slide rail, and two groups of slide rail seats are provided at the bottom of the mattress, and the two groups of slide rail seats are respectively provided corresponding to one of the slide rails and assembled on the slide rail, and the mattress moves linearly along the travel range of the slide rail and the mattress moves perpendicular to the transfer bed board.

[0012] Furthermore, a screw hole is provided on the connecting tube, and a threaded hole corresponding to the connecting tube is provided on the bottom of the transfer bed board, and a bolt is connected to the internal thread of the threaded hole, and the connecting tube and the transfer bed board are detachably mounted by the bolt.

[0013] Furthermore, the upper buffer cylinder and the lower buffer cylinder are both made of high-strength, wear-resistant and elastic engineering plastic material. The buffer cylinders made of this material can effectively reduce the overall weight of the transfer bed while ensuring the buffering performance and are not easily damaged by long-term use.

[0014] Furthermore, the surface of the mattress is provided with a breathable antibacterial layer, which is made of nano-silver ion antibacterial fabric, which can effectively inhibit the growth of bacteria, keep the surface of the mattress clean and hygienic, and provide a healthier use environment for patients; and there are several independent buffer support blocks inside the mattress, which are spaced apart from each other and can be adaptively adjusted according to the pressure of different parts of the patient's body, further improving the patient's comfort.

[0015] Furthermore, the heavy-duty push rod motor is an electric push rod with overload protection and automatic reset functions. When the motor load exceeds the rated value, the overload protection device is activated to prevent the motor from burning; after the fault is eliminated, the motor can automatically reset and resume normal operation; and the heavy-duty push rod motor is connected to the main support base and the transfer bed bed board through a detachable mounting base. The mounting base is made of high-strength aluminum alloy and is fixed by bolts, which facilitates the installation, disassembly and maintenance of the motor.

[0016] In summary, the present invention has the following beneficial effects: Through the mutual movement and coordination of multiple structures arranged in the bed shock-absorbing mechanism, when the transfer bed of the present application is moving and transporting, the bed shock-absorbing mechanism can be used to effectively absorb and disperse the vibration and impact energy from the ground, reducing the vibration transmitted to the patient and the bed board of the transfer bed. Compared with the use of a single bed in the cited documents, the present application can greatly reduce the bumps and vibrations during the transfer process by adding several groups of bed shock-absorbing mechanisms, so that the patient can maintain a more stable posture during the movement, reduce discomfort and anxiety, and at the same time help prevent the bed from sliding or suddenly moving on uneven roads, reducing the risk of falling or unexpected changes.

[0017] Several groups of heavy-duty push rod motors arranged on both sides of the main support base can be used to control the lifting and height adjustment of the transfer bed board; during use, the heavy-duty push rod motor can be integrated with the connection controller and synchronizer to accurately and smoothly adjust the height of the transfer bed board; compared with the manual adjustment method in the cited documents, the heavy-duty push rod motor of this application does not require medical staff to perform tedious manual operations, can perform height adjustment tasks more quickly, improve overall work efficiency, and can complete height adjustment in a short time, significantly shortening the time for patient transfer.

[0018] By setting slide rails on the bed board of the transfer bed, the mattress can move in a straight line along the slide rails. In combination with another bed with the same slide rail structure, the mattress can drive the patient to slide quickly in a straight line on different transfer beds, realizing rapid transfer between different beds without the patient getting out of bed.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0023] First embodiment; Reference Figure 1-5 As shown, a transfer bed for tumor radiotherapy in a preferred embodiment of the present invention comprises a horizontally arranged main support base 1; The upper end surface of the main support base 1 is equipped with a plurality of bed body damping mechanisms 3 along its transverse direction; A transfer bed board 4 is mounted on top of several groups of bed cushioning mechanisms 3; Two slide rails 7 are provided above the transfer bed board 4; Several sets of heavy-duty push rod motors 5 are installed on both sides above the main support base 1. The output ends of the several sets of heavy-duty push rod motors 5 are vertically arranged and extend to connect with the bottom of the transfer bed board 4; The bed shock absorbing mechanism 3 includes four bottom plates 31 arranged in a rectangular shape above the main support base 1. A lower buffer cylinder 32 is arranged above each of the four bottom plates 31. The four lower buffer cylinders 32 are hollow cylinders filled with buffer foam 34. An upper buffer cylinder 33 is sleeved on the outside of the four lower buffer cylinders 32. A base 35 is commonly supported above the four upper buffer cylinders 33. An oil pressure buffer 36 is supported and provided at the center of the upper end surface of the base 35 . A positioning seat 37 is installed on the upper end surface of the oil pressure buffer 36 . A connecting tube 38 is assembled on the upper end surface of the positioning seat 37 . The connecting tube 38 is connected to the bottom of the transfer bed board 4 .

[0024] In this embodiment, when the transfer bed of the present application is being moved and transferred, the bed body shock-absorbing mechanism 3 can be used to effectively absorb and disperse the vibration and impact energy from the ground, reducing the vibration transmitted to the patient and the transfer bed board 4. The four sets of bed body shock-absorbing mechanisms 3 can cooperate with the buffer foam 34 provided therein to initially absorb the vibration force. At the same time, through the arrangement between the oil pressure buffer 36 and the four sets of hydraulic buffers 311, the bed body shock-absorbing mechanism 3 can further absorb the remaining vibration force. Compared with the use of a single bed body in the cited documents, the present application can significantly reduce the bumps and vibrations during the transfer process by adding several sets of bed body shock-absorbing mechanisms 3, allowing the patient to maintain a more stable posture during the transfer process, reducing discomfort and anxiety, and at the same time helping to prevent the bed body from sliding or suddenly moving on uneven roads, reducing the risk of falling or unexpected changes.

[0025] Furthermore, several groups of heavy-duty push rod motors 5 arranged on both sides of the main support base 1 can be used to control the lifting and lowering height adjustment of the transfer bed board 4; in use, the heavy-duty push rod motor 5 can be integrated with the connection controller and the synchronizer, so as to accurately and smoothly adjust the height of the transfer bed board 4; compared with the manual adjustment method in the cited document, the heavy-duty push rod motor 5 of this application does not require medical staff to perform tedious manual operations, can perform height adjustment tasks more quickly, improve overall work efficiency, and can complete height adjustment in a short time, significantly shortening the patient transfer time.

[0026] It should be noted that the heavy-duty push rod motor 5 in the present application is equipped with a motor controller and a synchronizer, which can be used to control the number of ejection strokes and ejection direction of the heavy-duty push rod motor 5. During use, the power connection method of the heavy-duty push rod motor 5 is the existing technology, and the control circuit and synchronous rotation method can be achieved through simple programming by those skilled in the art. This is common knowledge in the art and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0027] Second embodiment; Reference Figure 2 and 4 As shown, the bottom of the upper buffer cylinder 33 fits in contact with the top of the buffer foam 34; ear seats 39 protrude from both sides of the positioning seat 37, and two connecting seats 310 are provided on both sides of the two ear seats 39 and the base 35. A hydraulic buffer 311 is installed between the two connecting seats 310 on the same side and adjacent to each other. The four hydraulic buffers 311 are installed at an angle on the sides of the positioning seat 37 and the base 35. In actual use, the connecting seats 310 provided on both sides of the ear seats 39 and the base 35 can be used to install the hydraulic buffers 311 at an angle. When the transfer bed of the present application is in motion, the four sets of hydraulic buffers 311 and oil pressure buffers 36 arranged at an angle can absorb a large amount of vibration and impact, reducing the mechanical stress on the transfer bed and its ancillary medical equipment such as radiotherapy equipment and monitoring instruments, thereby extending the service life of the equipment. At the same time, the impact of road vibration on tumor radiotherapy patients is reduced.

[0028] Third embodiment; Reference Figure 1-3 As shown, side beams 11 are integrally provided on both sides of the main support base 1. Sleeves 12 are integrally provided at both ends of the two side beams 11. Each sleeve 12 is fitted with a plug-in wheel sleeve 2. A locking bolt 13 is threadedly connected to the side of each sleeve 12. The side beams 11 can be used to install the sleeves 12, and the locking bolts 13 are threadedly connected to the side of the sleeves 12.

[0029] Fourth embodiment; Reference Figure 1-3As shown, the plug-in rod wheel sleeve 2 includes an insert rod 21 and a moving wheel 22. The insert rod 21 is arranged above the plug-in rod wheel sleeve 2 and inserted into the sleeve 12. The end of the locking bolt 13 passes through the sleeve 12 and extends to abut against the side wall of the insert rod 21; the moving wheel 22 is rotatably arranged in the plug-in rod wheel sleeve 2. When the plug-in rod wheel sleeve 2 and the moving wheel 22 are damaged after long-term operation, the user can loosen the locking bolt 13 to disengage the locking bolt 13 from the position limit of the plug-in rod 21. At this time, the plug-in rod 21 can drive the plug-in rod wheel sleeve 2 to be removed from the sleeve 12 as a whole. The user selects an appropriate plug-in rod wheel sleeve 2 and moving wheel 22, then inserts the plug-in rod 21 into the sleeve 12 again, and tightens the locking bolt 13 to limit and lock the plug-in rod 21 again. At this time, the plug-in rod wheel sleeve 2 can be replaced separately on the main support base 1. By replacing the entire plug-in type wheel cover 2 separately, the convenience and flexibility of management can be improved during use, and interruption of use caused by overall failure of the plug-in type wheel cover 2 can be avoided.

[0030] It should be noted that the inserted rod type wheel sleeve 2 is an existing mature structural component, which can be directly purchased on the market.

[0031] Fifth embodiment; Reference Figure 1-2 As shown, a transfer bed base 4 is provided with a side panel 6. A mattress 41 is supported above a slide rail 7, and two sets of slide rail seats 42 are provided at the bottom of the mattress 41. (It is worth noting that a locking structure is provided within the slide rail seat 42, which can be a conventional bolt.) The two sets of slide rail seats 42 are respectively provided for one of the slide rails 7 and assembled on the slide rail 7. The mattress 41 moves linearly along the travel range of the slide rail 7 and moves perpendicularly to the transfer bed base 4. During use, the slide rail 7 provided on the transfer bed base 4 allows the mattress 41 to move linearly along the slide rail 7 in conjunction with the slide rail seats 42. During this time, in conjunction with another bed with the same slide rail structure, the mattress 41 can move the patient laterally, thereby moving the mattress 41 to the other bed. At this point, the mattress 41 is located on the other bed and secured thereto, thereby enabling rapid transfer between different beds without the patient having to leave the bed. The provision of the slide rail 7 allows tumor radiotherapy patients to be transferred without moving their bodies.

[0032] Sixth embodiment; Reference Figure 4 As shown, the connecting tube 38 has a screw hole. The bottom of the transfer bed 4 has a threaded hole corresponding to the connecting tube 38, and a bolt is connected to the internal thread of the hole. The connecting tube 38 and the transfer bed 4 are detachably connected by the bolt. The screw hole provided on the connecting tube 38 can be used to match the appropriate bolt to complete the connection and installation between the connecting tube 38 and the transfer bed 4. The mattress 41 provided can improve the comfort and safety of the patient.

[0033] Specific implementation process: Step 1: When medical staff assist tumor radiotherapy patients lying on the mattress 41, the four sets of moving wheels 22 arranged at the bottom of the main support base 1 can realize the movement and transportation of the entire transfer bed of this application; when the moving wheels 22 are affected by the bumps of the ground during movement, the vibration force will be transmitted to the main support base 1, and the four sets of bed shock-absorbing mechanisms 3 arranged above the main support base 1 can make the four sets of bed shock-absorbing mechanisms 3 cooperate with the buffer foam 34 arranged therein to initially absorb the vibration force. At the same time, through the setting between the oil pressure buffer 36 and the four sets of hydraulic buffers 311, the bed shock-absorbing mechanism 3 can further absorb the remaining vibration force. Through the isolation setting of the four sets of bed shock-absorbing mechanisms 3 between the main support base 1 and the transfer bed board 4, the bed shock-absorbing mechanism 3 can be used to greatly reduce the vibration and impact energy from the ground, thereby reducing the vibration transmitted to the patient.

[0034] Step 2: During the transfer, the user can connect the heavy-duty push rod motor 5 to the power supply and the controller, so that the transfer bed board 4 connected to the output end of the heavy-duty push rod motor 5 can complete the height adjustment through the lifting and lowering adjustment of several groups of heavy-duty push rod motors 5; during this period, the heavy-duty push rod motor 5 can achieve precise height adjustment to ensure that the transfer bed board 4 reaches the optimal height under different environments and needs. At the same time, the heavy-duty push rod motor 5 can provide a smooth lifting process, avoiding the abrupt movement that may occur during manual adjustment, improving the patient's comfort, and greatly reducing the labor of medical staff.

[0035] Seventh embodiment; The upper buffer cylinder 33 and the lower buffer cylinder 32 are both made of high-strength, wear-resistant and elastic engineering plastic material. The buffer cylinders made of this material can effectively reduce the overall weight of the transfer bed while ensuring the buffering performance and are not easily damaged by long-term use.

[0036] The surface of the mattress 41 is provided with a breathable antibacterial layer, which is made of nano-silver ion antibacterial fabric, which can effectively inhibit the growth of bacteria, keep the surface of the mattress clean and hygienic, and provide a healthier use environment for patients; and there are several independent buffer support blocks inside the mattress 41, and the buffer support blocks are arranged at intervals with each other, which can be adaptively adjusted according to the pressure of different parts of the patient's body, thereby further improving the patient's comfort.

[0037] The heavy-duty push rod motor 5 is an electric push rod with overload protection and automatic reset functions. When the motor load exceeds the rated value, the overload protection device is activated to prevent the motor from burning out; after the fault is eliminated, the motor can automatically reset and resume normal operation; and the heavy-duty push rod motor 5 is connected to the main support base 1 and the transfer bed bed board 4 through a detachable mounting base. The mounting base is made of high-strength aluminum alloy and is fixed by bolts, which facilitates the installation, disassembly and maintenance of the motor.

[0038] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
