[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] The present invention provides a backup battery pack for a medical device as Figures 1 - 10 shown, which includes a battery pack mechanism 1. One side of the inner wall of the battery pack mechanism 1 is fixedly provided with a connector adjusting mechanism 7. One end of the bottom of the battery pack mechanism 1 is fixedly provided with a guide locking mechanism 8. One end of the battery pack mechanism 1 is fixedly provided with a rotating locking mechanism 9. Among them,

[0034] The connector adjusting mechanism 7 includes a connector positioning frame 701. An adjusting frame 702 is rotatably provided at the middle position on one side of the connector positioning frame 701. A positioning groove 707 is formed on one side of the inner wall of the adjusting frame 702. A moving frame 703 is slidably provided on one side of the inner wall of the positioning groove 707. A connecting seat 711 is fixedly provided at one end of the moving frame 703. A positioning lead screw 713 is rotatably provided at one end of the positioning groove 707. One end of the outer wall of the positioning lead screw 713 is threadedly connected to one end of the moving frame 703. A fixing groove 710 is formed on one side of the adjusting frame 702. A rotating wheel 712 is rotatably provided at the middle position of the fixing groove 710. One side of the rotating wheel 712 is fixedly connected to one end of the positioning lead screw 713. A positioning tooth ring 708 is fixedly provided at the middle position of the positioning groove 707. One side of the positioning lead screw 713 is rotatably connected to one side of the positioning tooth ring 708. A positioning gear 709 is meshed with one end of the inner wall of the positioning tooth ring 708. The size of the positioning tooth ring 708 is larger than that of the positioning gear 709, so that the positioning gear 709 will not get stuck during each meshing, avoiding the potential problem of being unable to engage due to the same size. Connector positioning seats 705 are fixedly provided on the four side edges of the outer wall of the connector positioning frame 701. The electrical connection ends 6 connected by the connecting lines 5 at one end of each connector positioning seat 705 are different. Limiting grooves 704 are formed on the four side edges of the inner wall of the connector positioning frame 701. One end of the connecting seat 711 corresponds to the position of one of the limiting grooves 704. The position of the rotating wheel 712 is higher than that of the protection plate 2, and a through groove is formed at the middle position of the protection plate 2, so that the rotation of the rotating wheel 712 along with the adjusting frame 702 is not affected by the protection plate 2. The position of the connecting seat 711 slides along the positioning groove 707 through the moving frame 703;

[0035] Installation grooves 102 are formed at both ends of both sides of the battery pack positioning frame 101. Auxiliary ears 103 are formed on both sides of the four installation grooves 102. Electrical connection ends 6 are snap-fitted at the middle positions of the four installation grooves 102. Each electrical connection end 6 has a different model to be suitable for different medical devices. Connecting lines 5 are fixedly provided at one end of each of the four electrical connection ends 6. One end of each of the four connecting lines 5 is electrically connected to one end of each of the four connector positioning seats 705;

[0036] By engaging the tooth surface of the positioning gear 709 with the tooth surface of the positioning gear ring 708, the positioning gear ring 708 drives the adjustment frame 702 to rotate, and the adjustment frame 702 drives the connecting seat 711 to rotate. When the connecting seat 711 rotates to the position of the corresponding connector positioning seat 705, the indicator light 3 corresponding to the connector positioning seat 705 lights up for prompting. Then, the rotating wheel 712 is toggled, so that the rotating wheel 712 drives the positioning screw rod 713 fixed at one end to rotate, and the moving frame 703 threadedly connected to the outer wall of one end of the positioning screw rod 713 slides along the inner wall of the positioning groove 707. Thus, the connecting seat 711 fixed at one end of the moving frame 703 stably penetrates through the inner wall of the corresponding connector positioning seat 705 under the guidance of the limiting groove 704, enabling the corresponding connecting wire 5 and the electrical connection terminal 6 of the connector positioning seat 705 to be stably powered. This facilitates the selection of different electrical connection terminals 6, provides precise and stable power supply for different devices, and increases the convenience of using the backup battery of medical equipment.

[0037] As a specific embodiment of the present invention, the battery pack mechanism 1 includes a battery pack positioning frame 101. Four side edges of the inner wall of the battery pack positioning frame 101 are fixedly provided with protective pads 104. The inner wall of the battery pack positioning frame 101 is fixedly provided with a battery fixing frame 105 through the protective pads 104. A plurality of engaging seats 106 are fixedly provided at the middle position of the battery fixing frame 105. A plurality of single cells 107 are engaged and provided in the middle position of the battery fixing frame 105 through the engaging seats 106. A circuit control chip 108 is fixedly provided at the top end of the battery fixing frame 105.

[0038] A protective plate 2 is fixedly provided on one side of the battery pack positioning frame 101.

[0039] A lifting handle 10 is fixedly provided at the middle position of the top of the battery pack positioning frame 101.

[0040] As a specific embodiment of the present invention, the guiding and locking mechanism 8 includes sliding grooves 801 opened at both ends on one side of the connector positioning frame 701. At the middle positions of the two sliding grooves 801, limit seats 804 are slidably arranged. At the bottom ends of the two limit seats 804, positioning rods 805 are fixedly arranged through the sliding grooves 801. One ends of the outer walls of the two sliding grooves 801 are respectively inserted and connected to one side of the connector positioning frame 701. At the middle positions of the outer walls of the two positioning rods 805, pressing blocks 803 are fixedly arranged. At the other ends of the outer walls of the two positioning rods 805, return springs 806 are inserted. At the other ends of the outer walls of the two positioning rods 805, they are respectively inserted and connected to one end of the battery pack positioning frame 101. At one ends of the two pressing blocks 803, a connecting block 802 is connected. On the four side edges of the outer wall of the adjusting frame 702, two guiding grooves 706 are opened. One ends of the outer walls of the two limit seats 804 are respectively engaged with the inner walls of two of the guiding grooves 706;

[0041] When the spare battery pack of the medical device needs to be used, press the connecting block 802 downward, so that the connecting block 802 drives the two pressing blocks 803 to drive the positioning rod 805 to move downward along the battery pack positioning frame 101, so that the return spring 806 inserted on the outer wall of the positioning rod 805 is inserted and connected to the inner wall of the battery pack positioning frame 101, so that the limit seat 804 fixed at the top end of the positioning rod 805 moves along the sliding groove 801, so that one ends of the two limit seats 804 are respectively separated from the corresponding guiding grooves 706;

[0042] When the adjusting frame 702 rotates to the corresponding position, release the connecting block 802, so that the return spring 806 inserted on the outer wall of the positioning rod 805 undergoes elastic deformation. In the natural state, the limit seat 804 fixed at the top end of the positioning rod 805 is stably inserted into the inner wall of the corresponding guiding groove 706. And because one side of the guiding groove 706 is designed to be open, the limit seat 804 plays a slight adjustment role when inserted and contacting with the guiding groove 706, which is convenient for correcting the slight deviation of the rotation of the adjusting frame 702, increasing the connection accuracy of the spare battery of the medical device, and when not adjusted, keeping the adjusting frame 702 stable and avoiding the potential problem of loose electrical connection.

[0043] As a specific embodiment of the present invention, the rotation locking mechanism 9 includes a mounting frame 901 fixed at the other end of the battery pack positioning frame 101. A fixing rod 902 is inserted through the middle position of the mounting frame 901. One end of the fixing rod 902 is fixedly connected to the middle position of the positioning gear 709. At one end of the outer wall of the fixing rod 902, a positioning ring 903 is fixedly arranged. Near the positioning ring 903 on the outer wall of the fixing rod 902, a positioning spring 904 is inserted. One end of the positioning spring 904 contacts one side of the inner wall of the mounting frame 901. The other end of the fixing rod 902 is fixedly provided with a positioning handle 905;

[0044] Press and position the positioning handle 905 on one side of the battery pack positioning bracket 101, so that the fixing rod 902 fixed at one end of the positioning handle 905 drives the positioning gear 709 fixed at one end to move, making the tooth surface of the positioning gear 709 mesh with the tooth surface of the positioning tooth ring 708. At the same time, rotate the positioning handle 905, so that the positioning handle 905 drives the positioning gear 709 to rotate through the fixing rod 902. When the positioning handle 905 is released, due to the elastic deformation of the positioning spring 904 inserted on one side of the outer wall of the fixing rod 902 and the stable positioning of the positioning ring 903 fixed on the outer wall of the fixing rod 902, in the natural state, the fixing rod 902 and the positioning handle 905 drive the positioning gear 709 to separate from the positioning tooth ring 708, preventing the connector adjustment mechanism 7 from being adjusted by accidental touch, which is beneficial to the stability of the connector adjustment mechanism 7.

[0045] As a specific embodiment of the present invention, multiple single cells 107 are electrically connected through a circuit control chip 108.
