It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Examples

Fig. 1 is a schematic structural diagram of a medical imaging apparatus according to an embodiment of the present invention. As shown in FIG. 1, a patient bed provided by the present embodiment is included in a medical imaging apparatus. This sick bed includes: the power receiving part 20 is electrically connected with the sickbed body 30, and the power receiving part 20 receives external power input in a wireless mode and supplies power to the sickbed body 30.

Note that, the input of the external power may be performed by the power output unit 10.

Wherein, the power receiving part 20 is arranged below the bed head of the hospital bed body 30, optionally, is fixedly arranged below the bed head of the hospital bed body 30, see fig. 2, and also can be flexibly connected with the hospital bed body 30 through a cable, i.e. the power receiving part 20 can be separated from the hospital bed body 30, see fig. 3. That is, the power receiving unit 20 and the bed body 30 may be fixedly installed or may be connected by a cable, and in any manner, it is only necessary that the power receiving unit 20 and the bed body 30 are integrated.

Wherein, the sickbed body 30 can move. Correspondingly, the power output part 10 is disposed at a certain position on the moving path of the patient bed body 30, optionally, the power output part 10 is fixedly disposed at the medical imaging device 40, see fig. 1, and also the power output part 10 can be flexibly connected with the medical imaging device 40 through a cable, see fig. 4. That is, as long as the medical imaging device 40 can apply a voltage to the power output portion 10, the specific arrangement of the power output portion 10 and the medical imaging device 40 is not limited.

When the patient bed body 30 moves to the target position, i.e. moves to the medical imaging device 40, the power receiving unit 20 and the power outputting unit 10 can be continuously aligned, i.e. the power outputting unit 10 contacts with the power receiving unit 20. Of course, the power output section 10 may be in wireless communication with the power receiving section 20.

In this embodiment, the specific setting manner of the power output unit 10 and the power receiving unit 20 can be set by a user according to actual requirements, and only when the hospital bed body 30 is in the working state, the power output unit 10 and the power receiving unit 20 are in the alignment state. This is because when the patient bed body 30 is in the working state, power is required to be supplied to the patient bed at any time, and when the power receiving portion is in contact with the power outputting portion, a certain electric field can be generated, and the electric field can supply power to the patient bed body, that is, high-frequency energy transfer between the power outputting portion 10 and the power receiving portion 20 is realized.

In order to apply the power supply bed to the medical imaging apparatus 40, the operating frequency of the power receiving unit 20 and the power outputting unit 10 is in the range of 20kHz to 20MHz, which is advantageous in that it is possible to prevent signal interference from occurring when other coils are operated during magnetic resonance.

On the basis of the above technical solution, the power output section 10 includes a transmitting coil 101 and a high frequency switch 102, see fig. 5. The frequency of the high frequency switch 102 is 50-100kHz, when a certain voltage is applied, the high frequency switch 102 is opened and closed according to a certain frequency, and the voltage value provided by the medical imaging equipment 40 can be converted into a variable electric field. The receiving coil 101 may be a non-magnetic coil or a magnetic coil, when the patient bed body 30 is applied to the medical imaging device 40, the receiving coil 101 may be a non-magnetic coil, and if the patient bed body 30 is applied to other medical devices, the receiving coil 101 may be a magnetic coil, and a user may determine the transmitting coil 101 according to actual needs without limitation.

On the basis of the above technical solution, if the hospital bed body 30 is applied to the medical imaging device, the transmitting coil 101 is made of a nonmagnetic core material. One end of the transmitting coil 101 is connected to the medical imaging device, the other end is connected to the high frequency switch 102, and the other end of the high frequency switch 102 is connected to the medical imaging device 40. When the medical imaging apparatus 40 supplies power to the power output section 10, a varying electric field can be generated by opening and closing the high-frequency switch 102. Due to the magnetic coupling, the transmitting coil 101 may generate a varying magnetic field in accordance with the varying electric field.

The power receiving section 20 further comprises a receiving coil 201, see fig. 6. The material of the receiving coil 201 may be the same as that of the transmitting coil 101, and the coil may be provided with or without a magnetic core according to the application scenario. When the receiving coil 201 is in contact with the transmitting coil 101, the receiving coil 201 can be converted into a varying electric field according to the varying magnetic field generated by the transmitting coil 101, i.e. high frequency energy transfer between coils is achieved.

For storing the electrical energy, the power receiving portion 20 further comprises an energy storage unit 202, see fig. 6 for continuation. The energy storage unit 202 is used for storing the electric energy generated by the receiving coil 201. The energy storage unit 202 may be installed at the head of the bed body 30 and in the bed body. The advantage of providing the energy storage unit 202 in this embodiment is that the energy storage unit 202 can also supply power to the patient bed body 30 under the condition that the receiving coil 201 and the transmitting coil 101 are not in contact with each other, and certainly can also supply power to at least one electronic device disposed on the patient bed body 30.

The input end of the rectifying and filtering unit 203 is connected to the receiving coil 201, and the output end is connected to the energy storage unit 202, and is configured to perform rectifying and filtering processing on the changed electric field to obtain a direct current voltage, and store charges corresponding to the direct current voltage in the energy storage unit 202.

The energy storage unit 202 is further configured to supply power to at least one load, wherein the at least one load includes an internal load and/or an external load built into the power supply bed.

Wherein, at least one load can be one, two or more. The built-in load may be a device provided in the hospital bed body 30, optionally a power assisting system. The external load can be understood as an external device plugged into the hospital bed body 30, and the energy storage unit 202 of the power receiving part 20 is required to supply power to the external device, and optionally, a physiological signal monitoring device, a life support device, an infusion device, and the like. Correspondingly, referring to fig. 2 or fig. 3, at least one external device power supply interface 301 is disposed on the hospital bed body 30, and the external device power supply interface 301 may be plugged into at least one external load.
