Description

Technical Field

[0001] The invention relates to the technical field of intensive care, in particular to a patient transport device for intensive care. Background Art

[0002] In the intensive care unit of a hospital, various critically ill patients are mainly admitted and treated. Many of these critically ill patients cannot move by themselves, and in many cases, the patient may be seriously ill. For this reason, a transfer vehicle is needed to quickly transfer the patient to the operating room. Although the existing transfer vehicle has a shock-absorbing function to provide shock-absorbing protection for the patient, it lacks the ability to follow and change the shock-absorbing force when the patient is transferred to the transfer bed. In this way, when the medical staff transfers the patient to the transfer vehicle, they will move the patient from the bed to the transfer vehicle by rotating the screw rod and other structures. However, the patient's condition may be too serious, causing the medical staff to have an anxious heart rate, and then the rotation speed will be too high when the screw rod and other mechanisms are rotated to transfer the patient, which will cause the inertia force generated on the shock-absorbing structure when the patient is moved to the transfer vehicle. The shock-absorbing capacity of the shock-absorbing structure always remains the same, and the shock-absorbing energy cannot be changed with the rotation speed of the medical staff, thereby increasing the vibration amplitude of the transfer vehicle, which is not conducive to the safety protection of the patient. For this reason, we propose a patient transfer device for intensive care. Summary of the invention

[0003] The object of the present invention is to provide a patient transfer device for intensive care, so as to solve the problem that the existing transfer vehicle proposed in the above background technology has a shock-absorbing function to provide shock-absorbing protection for patients, but lacks the ability to follow and change the shock-absorbing force when transferring the patient to the transfer bed. In this way, when the medical staff transfers the patient to the transfer vehicle, they will move the patient from the bed to the transfer vehicle by rotating the screw rod and other structures. However, the medical staff may have an anxious heart rate due to the patient's serious condition, and then the rotation speed will be too high when the screw rod and other mechanisms are rotated to transfer the patient. This will cause the inertial force generated on the shock-absorbing structure when the patient is moved to the transfer vehicle to be too large, and the shock-absorbing capacity of the shock-absorbing structure will always remain the same, and the shock-absorbing energy cannot be changed and adjusted according to the rotation speed of the medical staff, thereby increasing the vibration amplitude of the transfer vehicle, which is not conducive to the safety protection of the patient.

DETAILED DESCRIPTION

[0041] 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.

[0042] Embodiment 1

[0043] See also Figures 1 to 17 The present invention provides a technical solution: a patient transport device for intensive care, comprising:

[0044] A height adjustment mechanism 2, which is arranged on the top of the transfer vehicle 1, and is used to adjust the transfer height according to the height of the hospital bed;

[0045] A first vibration-changing adjustment mechanism 3, which is arranged on the top of the height adjustment mechanism 2, and is used to adjust the vibration-absorbing strength in the vertical direction according to the manual rotation speed of the medical staff;

[0046] A second vibration-changing adjustment mechanism 6, which is arranged on the top of the first vibration-changing adjustment mechanism 3, and is used to adjust the shock-absorbing strength in the lateral direction according to the manual rotation speed of the medical staff;

[0047] A pushing mechanism 4, which is arranged on the top of the second vibration-changing adjustment mechanism 6, and the second vibration-changing adjustment mechanism 6 is used to move the transfer mechanism under the patient to facilitate the transfer of the patient;

[0048] A shifting mechanism 5, which is arranged on the top of the pushing mechanism 4, and is used to adjust and move the position of the patient, so as to adjust the lying position of the patient and facilitate manual movement when transferring the patient to the bed;

[0049] The transmission mechanism 7 is arranged on one side of the first vibration-changing adjustment mechanism 3, and the transmission mechanism 7 is used to move the displacement mechanism 5 to facilitate the transfer of the patient.

[0050] By providing the height adjustment mechanism 2, after the transfer cart 1 is moved to the side of the patient's bed, the structure on the transfer cart 1 can be adjusted to the required height position according to the height of the bed, thereby facilitating the transfer of the patient from the bed to the transfer cart 1; by providing the shifting mechanism 5 and the pushing mechanism 4, when the patient is transferred from the bed, the shifting mechanism 5 can be moved under the patient's body by the pushing mechanism 4, and then the patient can be moved by the shifting mechanism 5, thereby reducing the workload of medical staff and reducing the harm to the patient; by providing the first vibration-changing adjustment mechanism 3, the second vibration-changing adjustment mechanism 6 and the transmission mechanism 7, when the medical staff rotates the second reciprocating screw 42 in the pushing mechanism 4, the speed of the second reciprocating screw 42 can be rotated by the medical staff to drive the first vibration-changing adjustment mechanism 3 and the second vibration-changing adjustment mechanism 6, according to the first vibration-changing adjustment mechanism 3 and the second vibration-changing adjustment mechanism 6. The centripetal force generated when the mechanism 6 is rotated is used to adjust the shock absorption strength. In this way, the faster the rotation speed of the first shock-changing adjustment mechanism 3 and the second shock-changing adjustment mechanism 6 is rotated, the greater the centripetal force generated, thereby reducing the shock absorption strength, thereby avoiding excessive vibration amplitude caused by a large inertial force on the patient's movement speed. When the first shock-changing adjustment mechanism 3 and the second shock-changing adjustment mechanism 6 are rotated, the slower the rotation speed, the smaller the centripetal force generated, thereby increasing the shock absorption strength. In this way, the shock absorption protection of the patient is improved. Dampers are installed inside the first shock-changing adjustment mechanism 3 and the second shock-changing adjustment mechanism 6. The dampers can dissipate the energy generated by the movement, so that the internal structures of the first shock-changing adjustment mechanism 3 and the second shock-changing adjustment mechanism 6 can quickly stabilize in the area. The cooperation of the above structures can provide convenience for medical staff and provide protection for the safety of patients.

[0051] When in use, after the transfer cart 1 is moved to the side of the bed, the universal wheels at the bottom of the transfer cart 1 are used to fix the position, and then the shifting mechanism 5 is adjusted to the required height position through the height adjustment mechanism 2 according to the height of the bed, and then the shifting mechanism 5 is moved by the pushing mechanism 4 to move the shifting mechanism 5 under the patient's body, and then the patient's body is moved by the shifting mechanism 5, and then the patient is moved to the top of the pushing mechanism 4 by the pushing mechanism 4. The rotation speed of the internal structure of the pushing mechanism 4 is driven by the first vibration-changing adjustment mechanism 3 and the second vibration-changing adjustment mechanism 6 through the transmission mechanism 7. The lateral vibration-changing adjustment mechanism 6 can be used to adjust the lateral vibration-absorbing strength of the patient's movement, and the vertical vibration-absorbing strength of the patient can be adjusted by the first vibration-changing adjustment mechanism 3.
