Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a positioning bed for treating tumor patients. Background Art

[0002] Elderly patients with malignant tumors are a group that requires special attention and meticulous care.

[0003] For tumors that are detected early and suitable for surgical treatment, surgery may be the preferred treatment. However, a comprehensive evaluation must be performed before surgery to ensure the safety of surgery. For some advanced or spread malignant tumors, chemotherapy or radiotherapy may be needed to control the growth and spread of the tumor. In the elderly, doctors usually adjust the dose and regimen according to the patient's physical condition and other diseases to reduce adverse reactions.

[0004] After the operation, when the cancer patient returns to the ward, the cancer patient needs to be transferred from the bed to the bed in the ward, and a transfer bed is needed at this time.

[0005] If the tumor patient is transferred by manual transport, the patient's body position changes greatly during the transfer process, which not only increases the labor intensity of medical staff, but also may cause secondary injuries to the patient, causing unnecessary pain to the patient. In order to overcome the above shortcomings, an electric transfer bed is available on the market, which includes a transfer bed body with a fixed bed frame assembly and a movable bed board assembly. The movable bed board assembly is connected to the fixed bed frame assembly through a movable bed board driving mechanism, and the movable bed board driving mechanism drives the movable bed board assembly to move horizontally on the fixed bed frame assembly.

[0006] Transferring patients via electric beds can reduce the labor intensity of medical staff. However, for patients after surgery for malignant bone tumors, who choose limb-preserving surgery with the assistance of chemotherapy, if an electric bed is used for transfer, the patient needs to be transferred from the operating bed to a movable bed board, and then from the movable bed board to the hospital bed. In this case, the patient needs to be transferred twice, and the patient's limbs may cause risks such as bleeding, hematoma or infection at the surgical site. Summary of the invention

DETAILED DESCRIPTION

[0050] like Figures 1 to 18 As shown, this is the first embodiment of the present invention.

[0051] A positioning bed used for the treatment of tumor patients, which is used to transfer patients after surgery for malignant bone tumors.

[0052] The present invention comprises a bed body 1 and a bed board 2. The bottom of the bed body 1 is provided with wheels, and the wheels are universal wheels, so that the bed body 1 can be easily moved in various environments, including narrow corridors, stairs and the like.

[0053] A mattress 3 is provided on the bed board 2 to ensure the comfort of the patient during the transfer process. The mattress 3 of the present invention is fixed with two leg pillows 38 by Velcro. When the tumor patient is on the mattress 3, the legs of the tumor patient are arranged in the area between the two leg pillows 38. The leg pillows 38 limit the position of the legs of the tumor patient. By limiting the affected limb of the patient, the pain stimulation caused by the activity can be reduced, which helps to alleviate the pain degree of the patient.

[0054] In the present invention, a trash can 40 is arranged at the bottom of the bed body 1 , and medical waste can be thrown into the trash can 40 .

[0055] The present invention fixes the slide rail 4 on the top of the bed body 1 by bolts, fixes the slider 5 on the bottom of the bed board 2, the slider 5 and the slide rail 4 constitute a sliding mechanism, the slide rail 4 and the bed body 1 form a slide groove, and the slider 5 extends into the slide groove, so that the slider 5 moves along the length direction of the bed body 1 on the slide rail 4, and the bed board 2 moves along the length direction of the bed body 1 on the bed body 1. The structure of the slide rail 4 and the slider 5 of the present invention is not limited to the structure in the drawings, as long as the slider 5 can move on the slide rail 4 and the slider 5 can be stably placed on the board of the bed.

[0056] After the bed board 2 slides to the set position of the bed body 1, it is limited on the bed body 1 by the limiting mechanism, which facilitates the movement and positioning of the bed. At the same time, the bed body 1 is fixed with a support block 37 by bolts, and the support block 37 supports the bottom surface of the bed board 2, increases the force bearing capacity of the bed board 2, and can ensure that the bed board 2 remains stable when moving without shaking or tilting, thereby improving the comfort and safety of the patient.

[0057] The limiting mechanism of the present invention includes a limiting mechanism 6, which includes a clamping mechanism and a limiting block 13. The clamping mechanism includes a clamping base 7 and a clamping plate 8. The clamping base 7 is fixed to the bed body 1 by bolts. Two upper and lower clamping plates 8 are installed on the clamping base 7, and a limiting groove 9 is formed between the two clamping plates 8. The limiting block 13 is fixed at the inner end a of the bed board 2. The medical staff applies a force to the outer end b of the bed board 2, and the limiting block 13 is clamped in the limiting groove 9. The clamping plate 8 is provided with a limiting protrusion 12, and the limiting block 13 is provided with a groove 14. The limiting protrusion 12 is embedded in the groove 14, so that the inner end a of the bed board 2 is limited on the bed body 1, which is convenient for pushing the bed board 2 from one end of the bed body 1 to the other end; when the outer end b of the bed board 2 is pulled outward, the limiting block 13 is disengaged from the limiting groove 9, which is convenient for moving the bed board 2. Considering that after long-term use, the clamping plate 8 will produce a small deformation, at this time the limit groove 9 will become larger, and the clamping effect of the clamping plate 8 on the limit block 13 will be reduced. In view of this technical problem, the present invention sets a notch 41 on the clamping base 7, and the clamping plate 8 is provided with a threaded rod 10, the threaded rod 10 passes through the notch 41 and moves vertically in the notch 41, and the threaded rod 10 is threadedly connected with a nut 11, which can adjust the height of the clamping plate 8 to avoid the deformed clamping plate 8 from being unable to press the limit block 13. When the clamping plate 8 presses the limit block 13, the nut 11 is tightened on the clamping base 7. The limit mechanism 6 acts on the inner end a of the bed board 2, and the transfer of the patient is not affected by the limit mechanism 6; at the same time, the limit mechanism 6 makes the movement of the bed board more controllable and predictable, and medical staff can more easily operate and control the movement of the bed board 2, thereby improving work efficiency.

[0058] On the basis of the structure based on the limiting mechanism 1 6, in order to increase the limiting effect of the bed body 1 on the bed board 2, another limiting mechanism is added: the limiting mechanism 2 15 includes a fixing plate 16 and a pressing plate 17, and the fixing plate 16 is fixed at the bottom of the bed body 1. In order to improve the force bearing capacity of the fixing plate 16, the present invention fixes a cross bar at the bottom of the bed body 1, and a support member 20 is fixed between the cross bar and the bed body 1 by bolts. The support member 20 is in an I-shaped shape, and a connecting member 21 is fixed between the support member 20 and the fixing plate 16 by bolts, so that the two fixing plates 16 are connected into an integral structure. The clamping plate 17 is installed on the fixing plate 16: the bed body 1 is provided with a through hole 35, the clamping plate 17 passes through the through hole 35, the clamping plate 17 is installed with a limiting protrusion 18 through a bolt, and both sides of the bed body 1 are provided with a groove 27, and the limiting protrusion 18 is embedded in the groove 27, so that the two clamping plates 17 limit the left and right sides of the bed board 2, and the bed body 1 limits the left and right sides of the bed board 2, thereby increasing the stability of the bed board 2. Considering that the groove 27 has a certain length, in order to increase the limiting effect of the clamping plate 17 on the bed board 2, the fixing plate 16 of the present invention is provided with a fixing bolt 19, and the clamping plate 17 is provided with a notch 22, the fixing bolt 19 passes through the notch 22, and the notch 22 moves horizontally on the fixing bolt 19, and the fixing bolt 19 is threadedly connected with a nut 42 to change the distance between the two clamping plates 17 on the same side. When the side of the limiting protrusion 18 is in close contact with the inner walls of the left and right sides of the groove 27, the nut 42 is tightened on the clamping plate 17, so that the clamping plate 17 can limit the left and right sides and front and back of the bed board 2, thereby improving the limiting effect of the bed body 1 on the bed board 2. The limiting mechanism 2 acts on the side of the bed board 2, and the transfer of the patient is not affected by the limiting mechanism 15; and the limiting mechanism 15 enables the bed board 2 to accurately reach the predetermined position when moving, which is convenient for medical staff to perform precise operations, such as adjusting the patient's position and performing nursing operations.

[0059] When the bed is moved and positioned, when an external force acts on the bed board 2, the bed board 2 will still detach from the limiting mechanism 1 6 and the limiting mechanism 2 15. Based on the structure of the limiting mechanism 1 6 and the limiting mechanism 2 15, in order to increase the limiting effect of the bed body 1 on the bed board 2, another limiting mechanism is added: the limiting mechanism includes a limiting mechanism 3, the limiting mechanism 3 includes a limiting shell 23 and a limiting block 2 24, and a fixing groove 36 is provided at the bottom of the bed body 1, and the limiting shell 23 is fixed in the fixing groove 36 by screws. The limiting shell 23 is provided with a cavity 25 and an opening, the opening and the cavity 25 are connected, the limiting block 24 passes through the opening and extends into the cavity 25, the limiting block 24 moves vertically in the cavity 25, a spring 26 is provided between the limiting block 24 and the limiting shell 23, the spring 26 is arranged in the cavity 25, the bottom of the bed board 2 is provided with a groove 39, when the bed board 2 slides to the set position of the bed body 1, the limiting block 24 is embedded in the groove 39; when the bed board 2 moves, the limiting block 24 acts on the bottom of the bed board 2, and the spring 26 is compressed. The limiting mechanism 3 acts on the bottom of the bed board 2, and the transfer of the patient is not affected by the limiting mechanism 3; and the limiting mechanism 3 enables the bed board 2 to accurately reach the predetermined position when moving, which is convenient for medical staff to perform precise operations, such as adjusting the patient's position, performing nursing operations, etc.

[0060] The limiting mechanism of the present invention can effectively prevent the bed board from shaking during movement or use, ensure the stability of the bed board, and reduce the risk of injury to patients or medical staff due to shaking.

[0061] Both sides of the bed 1 are provided with guardrails, which include a horizontal rod 32 and a vertical rod 31 fixed to each other. The vertical rod 31 is installed on the bed 1. The guardrail is a prior art, and the present invention does not further elaborate on the structure of the guardrail. A baffle 28 is provided between the two guardrails, and a positioning block 29 is provided at the bottom of the baffle 28. The positioning block 29 is provided with a positioning groove 30. The positioning groove 30 is clamped on the horizontal rod 32 and moves along the length direction of the bed 1. The baffle 28 is provided with a shielding cloth, and the shielding cloth is fixed to the baffle 28 by a clip 33, so that the shielding cloth can cover the baffle 28 and the guardrail. The clip 33 is an integrally formed structure, and a clamping mouth 34 is formed. The shielding cloth is quickly fixed to the baffle 28 through the deformation of the clamping mouth 34, and it is also convenient to remove the entire shielding cloth. The shielding cloth can shield the patient's chest and the affected limb after surgery to prevent other people (including other patients, medical staff or visitors) from peeping during transfer, thereby protecting the patient's privacy. At the same time, the baffle 28 can serve as a physical barrier to protect the patient.

[0062] The present invention specifically comprises the following steps when transferring:

[0063] S1. According to the position of the limit block 13 at the inner end a of the bed board 2, adjust the height of the two clamping plates 8 on the clamping base 7, and then adjust the size of the limit groove 9 between the two clamping plates 8.

[0064] S2. According to the length of the second groove 27 on the side of the bed body 1, the horizontal position of the pressing plate 17 is adjusted, thereby changing the distance between the two pressing plates 17 on the same side.

[0065] S3. Move the bed board 2 on the bed body 1 outward along the length direction of the bed body 1 so that the bed board 2 moves toward the operating table. The medical staff holds the bed board 2, and the other two medical staff transfer the patient from the operating table to the positioning bed board 2.

[0066] S4. Move the bed board 2 on the bed body 1 inward along the length direction of the bed body 1. At this time, the limit block 13 is clamped in the limit groove 9, and the limit protrusion 2 18 of the clamping plate 17 is embedded in the groove 27 on the side of the bed body 1, so that the two clamping plates 17 limit the left and right sides of the bed board 2. At the same time, the side of the limit protrusion 2 18 is tightly attached to the inner wall of the groove 27, so that the clamping plate 17 limits the front and back sides of the bed board 2, and the limit block 24 is embedded in the groove 3 39 at the bottom of the bed board 2. At this time, the bed board 2 is firmly fixed on the bed body 1.

[0067] S5. Install the baffle 28 on the horizontal bar 32 of the guardrail, cover the baffle 28 with the shielding cloth, and adjust the position of the baffle 28 on the horizontal bar 32 so that the baffle 28 is at the patient's abdomen. Then cover the guardrail and the patient's postoperative affected limb with the shielding cloth, and then use the clip 33 to clamp the shielding cloth and the baffle 28.

[0068] S6. Move the operating room in the positioning bed to the ward, then place the board body on the bed in the ward, and then apply force to the bed board 2, the limit block 13 disengages from the limit groove 9, the limit protrusion 2 18 of the clamping plate 17 disengages from the groove 2 27 on the side of the bed body 1, and the limit block 24 disengages from the groove 3 39 at the bottom of the bed board 2, and the bed board 2 is moved outward on the bed body 1 along the length direction of the bed body 1, and the entire bed board 2 is taken out from the bed body 1, and then the entire bed board 2 is moved to the board body of the bed, the slider 5 of the bed board 2 is supported on the board body of the bed, and then the clip 33 is removed, the shielding cloth is removed, and then the baffle 28 is removed from the horizontal rod 32 of the guardrail to complete the patient transfer operation.

[0069] In order to improve the stability of the bed board 2 on the bed board body, a small iron block can be placed in the gap between the slider 5 and the board body of the bed board 2. When the patient can get out of bed and walk after the operation, the patient can be transferred to another bed.

[0070] The present invention moves the bed board on the bed body along the length direction of the bed body, so that the bed board moves toward the operating table, and then transfers the patient from the operating table to the bed board of the positioning bed. When the patient is on the bed board of the positioning bed, the bed board is moved on the bed body along the length direction of the bed body, so that the bed board moves toward the limiting mechanism. After the bed board slides to the set position, the limiting mechanism on the bed body limits the bed board. At this time, the bed board is positioned at the set position of the bed body, and then the positioning bed is moved to the ward. In the ward, the bed board is directly removed from the limiting mechanism, and then the bed board is moved on the bed body along the length direction of the bed body and removed, and then the bed board is smoothly placed on the board body of the bed. In this process, there is no need to transfer the patient from the bed board of the positioning bed to the board body of the bed, which reduces the number of patient transfers. The design that the bed board can be removed makes the transfer process more convenient, so that they can complete the transfer and nursing work of the patient more quickly and accurately. It helps to reduce the risks of bleeding, hematoma or infection at the surgical site that may be caused by activities. At the same time, it can avoid excessive traction on the injured part during transfer, protect the surgical incision and surrounding soft tissue, and thus improve the quality of care.

[0071] Moreover, the bed board of the present invention can be removed, so that medical staff can more conveniently perform comprehensive and thorough cleaning and disinfection of the bottom of the bed board and the bed body, thereby effectively reducing the breeding of microorganisms such as bacteria and viruses and improving the sanitation level of the medical environment. The bed board of the present invention may be worn or damaged during use. The design of the bed board being removable allows medical staff to promptly discover and replace the damaged bed board, thereby extending the service life of the entire transfer bed.

[0072] The size design of the positioning bed of the present invention:

[0073] The length is usually between 1930mm and 2130mm, and some may even be longer to accommodate the needs of patients of different heights.

[0074] The width is generally between 660mm and 800mm. A bed with sufficient width can ensure the comfort and safety of the patient during the transfer process.

[0075] like Figures 19 to 26 As shown, this is the second embodiment of the present invention.

[0076] Based on the structure of the first embodiment, when the bed board 2 is moved outward on the bed body 1 along the length direction of the bed body 1 so that the bed board 2 moves toward the operating table, the medical staff needs to hold the bed board 2, and the other two medical staff transfer the patient from the operating table to the positioning bed board 2. In order to reduce the operation of the medical staff holding the bed board 2, the present invention adopts a driving structure supported on the ground. The specific design is:

[0077] The present invention provides a cavity 46 and a connection port 47 at the bottom of the bed board 2, and the cavity 46 and the connection port 47 are connected. A hydraulic cylinder 43 is provided in the cavity 46, and the hydraulic cylinder 43 is provided with a rotating shaft 49. The bed board 2 is provided with a rotating hole 53, and the rotating shaft 49 rotates in the rotating hole 53. The hydraulic cylinder 43 is provided with a piston rod 44. A limit block 3 48 is installed in the cavity 46, and the limit block 3 48 is provided with a groove 4 51. The connection port 47 is detachably connected with a cover plate 45.

[0078] When the bed board 2 is moved outward on the bed body 1 along the length direction of the bed body 1 and moved toward the operating table, the cover plate 45 is opened from the connection port 47, and the hydraulic cylinder 43 is rotated so that the hydraulic cylinder 43 is deployed from the connection port 47 and arranged vertically, and then the hydraulic cylinder 43 is started, and the hydraulic cylinder 43 controls the piston rod 44 to descend, and the chassis 54 at the bottom of the piston rod 44 is pressed against the ground. The hydraulic cylinder 43 can generate a large thrust and can bear the heavy-loaded bed board 2. At this time, the medical staff lifts the patient from the operating table Transfer to the positioning bed board 2. After the transfer is completed, control the piston rod 44 of the hydraulic cylinder 43 to return to the initial position, rotate the hydraulic cylinder 43 in the opposite direction, so that the hydraulic cylinder 43 is set in the cavity 46, and at the same time, the piston rod 44 of the hydraulic cylinder 43 is inserted into the groove four 51 of the limit block three 48, and then cover the cover plate 45 in the connecting port 47 to make the hydraulic cylinder 43 hidden. Then move the bed board 2 inward on the bed body 1 along the length direction of the bed body 1. The hidden hydraulic cylinder 43 does not affect the smooth movement of the bed board 2.

[0079] In order to quickly and conveniently install or remove the cover plate 45, the present invention makes the cover plate 45 into a metal structure, and then fixes four connecting posts 50 in the cavity 46, and the end of each connecting post 50 is embedded with a magnet 52, and the cover plate 45 is adsorbed by the magnet 52, so that the cover plate 45 is fixed in the connection port 47. No additional screws, clips or other fixing devices are required, and the connection can be achieved by simply aligning the cover plate 45 with the connection port 47, which reduces the difficulty and cost of installation. The cover plate 45 adsorbed by the magnet can usually be easily opened and closed without pushing, pulling or turning, which improves the convenience of use.
