[0031] This embodiment relates to a medical transfer bed, which is specifically used for transferring patients. This embodiment focuses on the case of transferring a patient from a hospital bed to a medical operating bed to explain the technical features of the present invention.

[0032] (1) When transferring a bed to this equipment:

[0033] Lower the guardrail 24 on one side of the device, place the device on the side of the bed, adjust the height to the bed through the lifting part, push the upper plate frame 11 (driving the belt mechanism 12) toward the end face of the bed to make one side of the patient contact one side of the belt mechanism 12, then the belt mechanism 12 starts, and the medical staff assists in pushing the patient from the other side. Driven by the belt line, the patient is gradually transferred to the upper end face of the belt line. When the patient is at a suitable position of the belt line, the belt line stops working, and the upper plate frame 11 is pushed to its original position;

[0034] (2) Transfer the patient of this device to the operating table:

[0035] In this embodiment, in order to quickly realize the operation and the post-operative transfer of patients, the operating table adopts the bed frame 2 structure, and then the device is moved to the bed position. At this time, the head end is docked with the bed frame 2, and the bed body 1 is pushed into the wheel groove 16 of the operating table (bed frame 2), and the patient is pushed onto the operating table for adaptation.

[0036] (3) Transfer after the operation:

[0037] Similarly, after the operation is completed, operations (2) and (1) are reversed to allow the patient to return to the bed.

[0038] The guide rail member 14 described in this embodiment includes a guide rail base 141 and a guide rail slider 142. The guide rail slider 142 is slidably set on the guide rail base 141. The guide rail base 141 is provided with a limiting groove body 143. The middle part of the guide rail slider 142 is provided with a limiting slider 144. The limiting slider 144 is slidably set in the limiting groove body 143. The limiting slider 144 is limitedly contacted at both ends of the limiting groove body 143. Therefore, the belt mechanism 12 can be pushed to both sides while being limited by the limiting slider 144 contacting the end of the limiting groove 37 at a position of up to half to one side. It is convenient to use and also convenient to cooperate with the bed body 1 of the transfer party, and has good adaptability.

[0039] In order to facilitate the adaptation and position fixing of the bed frame 2 and the bed body 1 in this embodiment, the bed frame 2 is provided with a longitudinal driving component, and the longitudinal driving component includes a synchronous belt line 31, a connector and a lock hook seat 31. The synchronous belt line 31 is arranged on the upper end surface of the bed frame 2, and the connector is fixed on the belt end surface of the synchronous belt line 31. The connector includes a fixed seat 33 and a limit block 34. The limit block is provided with a slot for installing the limit block 34. The two sides of the limit block are slid up and down on the slot through a connecting shaft. The connecting shaft is provided with a first return spring 36 so that the limit block is in a non-pressurized state and is on the upper side. The front side of the connector is provided with a limit slot 37, and the front side of the limit slot 37 is provided with an opening, and the front side opening position is adapted to the fixed seat 33. The upper end surface of the fixed seat 33 on the inner side of the limiting groove 37 is higher than the upper end surface of the limiting block 34. The lock hook seat 31 is fixed on the lower plate frame 13. The lock hook seat is provided with a hook lock block 38. The front side of the limiting block 34 is provided with a first inclined surface 39 inclined forward and downward, so that the hook lock block 38 moves inward and adapts to the first inclined surface 39 to push the limiting block 34 downward and fall into the limiting groove 37. The outer side of the support plate 23 is provided with a roller 30 adapted to the first inclined surface 39. The first inclined surface 39 is pushed forward and adapted to the roller 30, pushing the limiting block to move downward to make it disengage from the position of the limiting groove 37. The inner side of the support plate 23 is provided with a first electromagnetic adsorption lock 171, and the fixed seat 33 is provided with a first adsorption piece 172 adapted to the first electromagnetic adsorption lock 171.

[0040] When the bed body 1 enters the bed frame 2, the guide wheel 15 of the bed body 1 is adapted to the wheel groove 16 to be entered into the bed frame 2, and the bed body 1 is pushed inward. At this time, the hook lock block 38 contacts the limit groove 37, pushing the mounting seat to move inward, and the first inclined surface 39 of the limit block is adapted to the contact of the roller 30. The limit block is reset upward under the action of the first reset spring 36, so that the lock hook block is clamped in the limit groove 37. At this time, the synchronous belt starts to drive, which drives the bed body 1 to move inward as a whole. This structural setting saves trouble and labor, and greatly reduces the labor intensity of medical staff. After the bed 1 reaches the bottom, the first adsorption member 172 is adapted to the first magnetic adsorption lock so that the bed 1 is kept fixed as a whole on the bed frame 2. Similarly, in the operation of pushing out the bed 1, the first adsorption member 172 and the first magnetic adsorption lock are released from adsorption. Since the lock hook block is limited in the limit groove 37, the bed 1 is pushed to move outward with the movement of the synchronous belt. When the first inclined surface 39 is adapted to contact with the roller 30, the limit block 34 is pushed to move downward, and the lock hook block is separated from the limit groove 37, so that the bed 1 is completely separated from the bed frame 2 and enters another bed frame 2.

The second conductive sheet 186 is connected to the control circuit port of the controller module through an electrical lead. When the bed body 1 is completely inserted into the bed frame 2, the male plug-in is plugged and adapted with the female plug-in. The front side of the bed frame 2 is provided with A main pushing handle 27 and an auxiliary pushing handle 19 are provided on the front side of the upper plate frame 11, which are convenient for pushing and pulling during use.
