When an element is considered to be "provided in" another element, it may be directly provided in the other element or there may be an intermediate element at the same time.

[0035] The present utility model provides a medical transport flat trolley 100, as Figures 1 to 5As shown in the figure, it includes: a first support plate 1, a second support plate 2, a lifting assembly 3, a transport stretcher 4, and two side plates 5. The first end of the lifting assembly 3 is installed on the second support plate 2, and universal wheels 21 are provided under the second support plate 2; the first support plate 1 is installed at the second end of the lifting assembly 3; the two side plates 5 are respectively installed on both sides of the first support plate 1, and an installation position is formed between the inner sides of the two side plates 5 and the upper end surface of the first support plate 1. The transport stretcher 4 is detachably arranged at the installation position; the side plates 5 extend along the length direction of the transport stretcher 4, and the two side plates 5 are in contact with both sides of the transport stretcher 4. Specifically, when using the flat cart 100 to transport a patient, since the transport stretcher 4 is detachable from the first support plate 1, the transport stretcher 4 is placed on the first support plate 1, and then the patient is placed on the transport stretcher 4. By moving the flat cart 100, the patient is transported to the designated department; during the transfer, only the transport stretcher 4 needs to be lifted from the first support plate 1, and the transport stretcher 4 transfers the patient to the hospital bed. Therefore, when the patient is placed on the hospital bed using the transport stretcher 4, after the patient can move later, the transport stretcher 4 on the hospital bed is removed, which can avoid directly moving the patient from the flat cart 100 to the hospital bed and avoid causing secondary harm to the patient.

[0036] Moreover, by setting the lifting assembly 3, the first support plate 1 can be lifted up and down to a preset position. The first support plate 1 drives the transport stretcher 4 to move when moving, which is convenient for medical staff to transfer patients; moreover, when the patient lies on the transport stretcher 4, the two side plates 5 can also be in contact with both sides of the patient to play a protective role, avoiding the patient falling off the transport stretcher 4 during transportation and improving the stability of transporting patients.

[0037] In some embodiments, such as Figure 2 and Figure 5 As shown in the figure, the medical transfer flat cart 100 has four first limiting members 11, and the four first limiting members 11 are arranged at the four corners of the first support plate 1; the first limiting member 11 has a limiting groove 111, and the limiting groove 111 is used to accommodate at least a part of the transport stretcher 4. Specifically, when the transport stretcher 4 is placed on the first support plate 1, the two ends of the transport stretcher 4 cooperate with the first limiting members 11, and at least a part of the transport stretcher 4 is stuck in the limiting groove 111, improving the stability of the transport stretcher 4 on the first support plate 1; moreover, the limiting groove 111 can also play a certain positioning role in the placement of the transport stretcher 4, increasing the contact area between the transport stretcher 4 and the first support plate 1, and further improving the stability of the first support plate 1 in supporting the transport stretcher 4.

[0038] Preferably, as Figure 1 and Figure 3As shown in the figure, the transport stretcher 4 includes a first support rod 41, a second support rod 42, and a support pad 43. The first end of the support pad 43 is mounted on the first support rod 41, and the second end of the support pad 43 is mounted on the second support rod 42. The first limiting member 11 is sleeved outside the first support rod 41 or the second support rod 42, and at least a part of the first support rod 41 or the second support rod 42 is received in the limiting groove 111. Specifically, the two ends of the first support rod 41 are respectively engaged with two of the limiting grooves 111, and the two ends of the second support rod 42 are respectively engaged with the other two second limiting grooves 111. The first limiting member 11 improves the stability of the first support rod 41 and the second support rod 42 on the first support plate 1; the support pad 43 is used to contact the patient, and the support pad 43 transmits the pressure to the first support rod 41 and the second support rod 42. Two medical staff pick up the ends of the first support rod 41 and the second support rod 42 from the front and back, and the patient on the transport stretcher 4 can be lifted and transferred, further avoiding secondary injury to the patient during the transfer process. In some embodiments, the support pad 43 can be made of a flexible material to increase the softness of the support pad 43 and improve the comfort of the patient on the support pad 43.

[0039] Moreover, the first limiting member 11 has an opening, and the first support rod 41 and the second support rod 42 enter the limiting groove 111 through the opening, realizing the detachable installation of the transport stretcher 4 and the first support plate 1.

[0040] In some embodiments, such as Figure 1 and Figure 2 As shown in the figure, there are two sets of lifting assemblies 3. The two sets of lifting assemblies 3 are both mounted on the second support plate 2 and are arranged oppositely. Specifically, two sets of lifting assemblies 3 are used to support the first support plate 1 simultaneously to improve the stability of the first support plate 1; moreover, the two sets of lifting assemblies 3 can lift the first support plate 1 simultaneously, or one of the sets of lifting assemblies 3 can be used to raise one end of the first support plate 1 to make the first support plate 1 inclined. In this way, in the absence of the transport stretcher 4, the first support plate 1 is inclined, which can better assist the patient to move on the first support plate 1.

[0041] Preferably, as Figure 4As shown in the figure, the lifting assembly 3 includes a motor 32, a lead screw 35, a first support column 31, a second support column 37, and a moving block 36. The first support column 31 is installed on the second support plate 2, the motor 32 is installed on the second support plate 2, at least part of the lead screw 35 is installed inside the first support column 31 and is rotatably connected to the first support column 31; the moving block 36 is sleeved outside the lead screw 35 and is in threaded cooperation with the lead screw 35. The first end of the second support column 37 is installed on the moving block 36, and the first support plate 1 is installed on the second end of the second support column 37; the moving block 36 has a guide block, and the first support column 31 has a guide groove that slidably cooperates with the guide block. Specifically, by rotatably connecting the lead screw 35 to the first support column 31, the first support column 31 can use a bearing to support the lead screw 35 to reduce the pressure exerted by the lead screw 35 on the motor 32; the motor 32 is used to drive the lead screw 35 to rotate. Since the moving block 36 is sleeved outside the lead screw 35 and the moving block 36 has a guide block, the guide groove restricts the moving direction of the guide block. When the lead screw 35 rotates, the moving block 36 is restricted by the guide block and cannot rotate, and a frictional force is generated between the lead screw 35 and the inner wall of the moving block 36. This frictional force pushes the moving block 36 to move along the length direction of the lead screw 35, thereby driving the second support column 37 to move up and down, realizing the up and down lifting of the first support plate 1.

[0042] In other embodiments, the lifting assembly 3 can also use a hydraulic cylinder, a pneumatic cylinder, or an electric push rod to realize the up and down movement of the first support plate 1, and no special limitation is made here.

[0043] Preferably, as Figure 4 shown, the lifting assembly 3 also has a first helical gear 33 and a second helical gear 34. The first helical gear 33 is installed at the output end of the motor 32 and is arranged inside the first support column 31; the second helical gear 34 is sleeved outside the lead screw 35, and the second helical gear 34 is rotatably installed on the second support plate 2, and the first helical gear 33 meshes with the second helical gear 34. Specifically, by meshing the first helical gear 33 with the second helical gear 34, the motor 32 can be arranged on the second support plate 2, and the output direction of the motor 32 intersects with the length direction of the lead screw 35, so that the motor 32 can be avoided from directly receiving the pressure of the lead screw 35; moreover, the meshing of the first helical gear 33 and the second helical gear 34 can be used as a speed reducer to change the transmission ratio of the lead screw 35.

[0044] Preferably, as Figure 4 shown, the first support column 31 has a second limiting member 311 inside. The second limiting member 311 is arranged above the first helical gear 33, and the second limiting member 311 is used to abut against the moving block 36. Specifically, the second limiting member 311 is used to limit the downward movement of the moving block 36 to prevent the downward movement of the moving block 36 from interfering with the rotation of the first helical gear 33 and improve the stability of the first helical gear 33 and the second helical gear 34 during operation.

[0045] Preferably, as Figure 1 and Figure 2 shown, the first support column 31 and the second support column 37 are of a hollow rectangular structure. The first support column 31 is sleeved outside the second support column 37, and the second support column 37 is in sliding fit with the first support column 31. The moving block 36 is installed inside the second support column 37. Specifically, the first support column 31 is sleeved outside the second support column 37. Due to the rectangular shape of the first support column 31, the second support column 37 cannot rotate inside the first support column 31, so as to play a role in restricting the rotation of the moving block 36, and further realize the movement of the moving block 36 in the length direction of the lead screw 35.

[0046] Preferably, as Figure 4 shown, the lifting assembly 3 further has a first support arm 38 and a second support arm 39. The first support arm 38 and the second support arm 39 are both installed on the second support column 37. The first support arm 38, the second support arm 39 and the second support column 37 form a Y-shaped support structure; both the first support arm 38 and the second support arm 39 have pin shafts 381. The first support plate 1 has a shaft hole for cooperating with the pin shaft 381, and the bottom of the first support plate 1 is in rotational fit with the pin shaft 381. Specifically, the second support column 37 supports the first support plate 1 through the first support arm 38 and the second support arm 39, increasing the connection points between the second support column 37 and the first support plate 1 and improving the stability of the first support plate 1. Moreover, the bottom of the first support plate 1 is in rotational fit with the first support arm 38 and the second support arm 39. When one of the lifting assemblies 3 raises one end of the first support plate 1, the connection point between the first support plate 1 and the first support arm 38 or the second support arm 39 is relatively flexible, avoiding interference when the first support plate 1 is raised.

[0047] In some embodiments, as Figure 1 and Figure 2 shown, the medical transport stretcher 100 further has a battery 6, a control panel 7, and an electric blanket 12. The battery 6 is installed on the second support plate 2, the electric blanket 12 is installed on the first support plate 1, and the control panel 7 is installed on the side wall of the first support plate 1. The control panel 7 has a control circuit, and the battery 6, the motor 32, and the electric blanket 12 are all electrically connected to the control circuit of the control panel 7. Specifically, the electric blanket 12 heats the transport stretcher 4 on the first support plate 1. In areas with relatively cold weather, the electric blanket 12 can keep the patient warm, thus improving the comfort of the patient during transportation. Moreover, the battery 6 supplies power to the motor 32 and the electric blanket 12, and the lifting assembly 3 and the electric blanket 12 are controlled to operate through the control panel 7, facilitating the medical staff to control the stretcher 100.

[0048] It should be noted that in the medical transfer stretcher 100, by providing a detachable transport stretcher 4 on the first support plate 1, secondary injuries to patients during transportation are avoided; and the lifting assembly 3 is used to move the first support plate 1 up and down to facilitate medical staff in transferring patients. In other medical transfer stretchers 100, using the detachable transport stretcher 4 provided on the first support plate 1 to reduce secondary injuries to patients are all within the protection scope of this application.
