Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sterile packaging rechargeable kit for medical power tools. Background Technology

[0002] Rechargeable battery-powered medical power tools are widely used, but due to the inherent characteristics of the batteries, they cannot be sterilized using the high-temperature methods commonly used in medical institutions, and other sterilization methods are not convenient to implement in hospitals and medical facilities. Currently, the common practice is to install the batteries before surgery through a sterile channel, which increases the risk of infection. If the batteries are sterilized using non-high-temperature methods such as ethylene oxide and then sterilized and aseptically packaged, they can be installed on the power tool before surgery, reducing the risk of infection. However, due to factors such as transportation and distribution before use, the battery's lifespan is uncertain, and factors such as the natural degradation of battery power cannot guarantee that the battery has sufficient charge to meet the needs of the power tool during surgery. Preoperative battery power testing and charging are required, but how to perform power testing and charging without damaging the sterile packaging remains a challenge.

[0003] Therefore, there is a need to develop a sterile packaging rechargeable kit for medical power tool batteries to address the aforementioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a sterile packaging rechargeable kit for medical power tool batteries, which enables power detection and charging without damaging the packaging.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a sterile packaging rechargeable kit for medical power tools, comprising a battery device packaged together after sterilization, a first housing, a first cable, a first fixing connector, and medical dialysis paper. The first housing is a blister-formed plastic housing with recessed grooves for holding the battery device, a cable routing groove, and a fixing connector groove. The first cable is laid in the cable routing groove, with one end electrically connected to the battery device via the adapter and the other end electrically connected to the first fixing connector. The first fixing connector is fixed in a first mounting hole on the side wall of the fixing connector groove. The medical dialysis paper seals the top opening of the first housing.

[0007] Furthermore, the battery device is specifically a battery pack, and a battery pack groove is recessed on the first housing. The battery pack is placed in the battery pack groove and is fixed by a snap-fit ​​on its side wall; the fixing adapter groove is arranged parallel to one side of the battery pack groove.

[0008] Furthermore, it also includes a second cable, a second fixing connector, and a second housing. The second housing is a basin-shaped housing fitted around the periphery of the first housing. The second fixing connector is fixed to a second mounting hole on the side wall of the second housing. The second cable is electrically connected between the second fixing connector and the first fixing connector. The top edge of the second housing is sealed to the medical dialysis paper.

[0009] Furthermore, the installation positions of the second fixed connector and the first fixed connector are diagonally arranged.

[0010] Furthermore, it also includes a third cable, a third fixing head, and an outer casing. The outer casing is a cuboid shell structure with an integrally formed cover on the long side of the top opening. The cover can be fastened to the top opening of the outer casing. The outer casing is fitted around the second shell. The third fixing head is fixed to the side wall of the outer casing. The third cable is electrically connected between the second fixing head and the third fixing head.

[0011] Furthermore, the installation positions of the second fixing joint and the third fixing head are diagonally arranged.

[0012] Furthermore, the first fixed connector includes a connector body, rubber gaskets, metal gaskets, and a lock nut. The connector body is cylindrical and has a convex ring at its outer end. The convex ring and the lock nut clamp the edge of the first mounting hole. Two rubber gaskets are respectively placed on both sides of the first mounting hole, and the metal gasket is stacked between the inner rubber gasket and the lock nut.

[0013] Furthermore, the battery cell connection of the connector body adopts any one of DC interface, USB interface, TYPE-C interface, single-phase interface and three-phase interface. The battery cell is welded to the first cable and the interface element is sealed and isolated by plastic injection molding. The structure of the second fixed connector and the third fixed connector is the same as that of the first fixed connector.

[0014] Furthermore, the first housing is also recessed with a handle groove and a power tool body groove, the handle groove holding the handle of the power tool, and the power tool body groove holding the power tool body.

[0015] Furthermore, the battery device is specifically an integrated power tool, and the first housing has a recessed groove for holding the integrated power tool.

[0016] Compared with existing technologies, this utility model provides a sterile packaging rechargeable kit for medical power tools. Through a fully enclosed battery device and a first cable electrically connected to a first fixed connector, the battery device is electrically connected to an external charger and power detection device without direct contact. This allows the battery device to be charged while in a sterile packaging state, ensuring it can be charged at any time. This maintains sufficient power during surgery, guaranteeing the power needs during the procedure.

[0017] Furthermore, by adding a second shell to enclose the first shell, a buffer layer is added, further reducing the risk of external environmental contamination of the internal battery components. The outer casing provides effective safety protection for the second shell, reducing the risk of impact deformation. The addition of a third fixing head allows charging of the battery components without disassembling the outer casing. Rubber gaskets on both sides of the first mounting hole, when compressed, provide a seal, preventing outside air from entering the packaging. The addition of metal gaskets prevents the rubber gaskets from being damaged by the rotating lock nut. A wide range of battery cell connection methods are available, ensuring compatibility. Increased packaging space allows for aseptic packaging of the handle and main body of the power tool, enabling assembly together during use and reducing the risk of infection. The integrated power tool's built-in battery can also be charged directly. Attached Figure Description

[0034] Example 1

[0035] In one specific implementation, such as Figures 1-8 As shown, the sterile packaging rechargeable kit for medical power tools of this utility model includes a battery device packaged together after sterilization, a first housing 1, a first cable 2, a first fixing connector 3, and medical dialysis paper 9. The sterilization method is ethylene oxide sterilization. The first housing 1 is a vacuum-formed plastic housing with recessed grooves for holding the battery device, a cable routing groove 102, and a fixing connector groove 103. The first cable 2 is laid in the cable routing groove 102. One end of the first cable 2 is electrically connected to the battery device through the adapter, and the other end is electrically connected to the first fixing connector 3. The first fixing connector 3 can be connected to an external charger or a power detection device. The first fixing connector 3 is fixed in the first mounting hole 104 on the side wall of the fixing connector groove 103. The medical dialysis paper 9 seals the top opening of the first housing 1. The medical dialysis paper 9 is made of medical paper and a heat-sealing coating, and is heat-sealed to the top opening of the first housing 1. Figure 4 In the middle, medical dialysis paper 9 is marked with a double-dotted line.

[0036] The battery device, along with the first cable 2, is electrically connected to the first fixed connector 3 in a fully enclosed manner, allowing for electrical connection to external chargers and power detection devices without direct contact. This enables the battery device to be charged while in sterile packaging, ensuring it can be charged at any time while in sterile packaging. This provides sufficient power during surgery to meet the electrical needs of the procedure.

[0037] Specifically, such as Figures 2-6As shown, the battery device is specifically a battery pack 11. A battery pack groove 101 is recessed on the first housing 1. The battery pack 11 is placed in the battery pack groove 101 and is fixed by the snap-fit ​​on its side wall. The fixing adapter groove 103 is arranged parallel to one side of the battery pack groove 101.

[0038] In one specific implementation of this embodiment, such as Figures 2-7 As shown, the aseptic packaging rechargeable kit for medical power tools of this utility model also includes a second cable 4, a second fixing connector 5, and a second housing 8. The second housing 8 is a basin-shaped housing fitted around the first housing 1, with its top opening flush with the first housing 1. The second fixing connector 5 is fixed to the second mounting hole 801 on the side wall of the second housing 8. The second cable 4 is electrically connected between the second fixing connector 5 and the first fixing connector 3. The top edge of the second housing 8 is sealed to the medical dialysis paper 9, and the two are also heat-sealed. The first housing 1 and the second housing 8 are made of PEG or PET material.

[0039] Specifically, such as Figure 5 As shown, the installation positions of the second fixed connector 5 and the first fixed connector 3 are diagonally arranged.

[0040] By adding a second housing 8 to enclose the outer perimeter of the first housing 1, a buffer layer is added, further reducing the possibility of external environment infecting the internal battery devices.

[0041] In one specific embodiment of this invention, the sterile packaging rechargeable kit for medical power tools further includes a third cable 6, a third fixing head 7, and an outer box 10. The outer box 10 is a cuboid shell structure with a cap 1001 integrally formed on the long side of its top opening. The cap 1001 can be folded and fastened to the top opening of the outer box 10. The outer box 10 is fitted around the second shell 8 and is made of cardboard. The third fixing head 7 is fixed to the side wall of the outer box 10. The third cable 6 is electrically connected between the second fixing head 5 and the third fixing head 7.

[0042] Specifically, such as Figure 1 As shown, the outer box 10 is covered with a plastic seal film, which serves as a waterproof barrier.

[0043] Specifically, such as Figure 5 As shown, the installation positions of the second fixing joint 5 and the third fixing head 7 are diagonally arranged.

[0044] By adding an outer box 10 to enclose and fasten the second housing 8, the second housing 8 can be effectively protected and the risk of deformation due to impact can be reduced. At the same time, the addition of a third fixing head 7 allows the battery device to be charged without disassembling the outer box 10.

[0045] In one specific implementation of this embodiment, such as Figure 8 As shown, the first fixed connector 3 includes a connector body, rubber washers 301, metal washers 302, and lock nuts 303. The connector body is cylindrical and has a raised annular platform at its outer end. The raised annular platform and the lock nut 303 clamp the edge of the first mounting hole 104. Two rubber washers 301 are respectively placed on both sides of the first mounting hole 104, and the metal washers 302 are stacked between the inner rubber washers 301 and the lock nut 303.

[0046] Specifically, such as Figure 8 As shown, the battery cell connection of the connector body adopts any one of the following: DC interface, USB interface, Type-C interface, single-phase interface, and three-phase interface. The battery cell is welded to the first cable 2, and the interface components are sealed and isolated by plastic injection molding.

[0047] Furthermore, the structures of the second fixed joint 5 and the third fixed joint 7 are consistent with those of the first fixed joint 3.

[0048] By adding rubber gaskets 301 on both sides of the first mounting hole 104, the rubber gaskets 301 can be compressed to achieve a sealing and isolation effect, preventing outside air from entering the packaging. The addition of metal gaskets 302 can prevent the rubber gaskets 301 from being damaged by the rotating lock nut 303. By flexibly selecting various battery cell connection methods, the matching range is wide.

[0049] The assembly process of the aseptic packaging rechargeable kit for medical power tools in this embodiment is as follows: Each component is sterilized. The battery pack 11 is installed into the first housing 1. The first cable 2 is laid in the wiring groove 102, with one end of the first cable 2 electrically connected to the battery pack 11 via an adapter, and the other end electrically connected to the first fixing connector 3. Medical dialysis paper 9 is heat-sealed to the top edge of the first housing 1. The first housing 1 is then installed into the second housing 8, with the second cable 4 electrically connected between the second fixing connector 5 and the first fixing connector 3. The outer ring of the medical dialysis paper 9 and the top edge of the second housing 8 are heat-sealed together. The entire assembly is placed into the outer box 10, with the third cable 6 electrically connected between the second fixing connector 5 and the third fixing connector 7. The cover 1001 is then fastened. Ethylene oxide is used for sterilization again, and the outer box 10 is sealed with a plastic sealant.

[0050] The usage process of the sterile packaged rechargeable battery kit for medical power tools in this embodiment is as follows: Before entering the operating room, tear a small opening in the plastic seal of the third fixing head 7. Connect a dedicated power detection device to the third fixing head 7 to check if the battery pack 11 has sufficient power. If it is low on power, connect the charger to the third fixing head 7 to charge it. Ensure that the battery pack 11 is fully charged before entering the operating room. When using it in the operating room, tear off the plastic seal, open the cover 1001, and remove the plastic shell. Remove the medical dialysis paper 9, remove the battery pack 11, and separate it from the first cable 2 to separate the battery pack 11 from the packaging. Install the battery pack 11 into the battery compartment of the power tool for use during surgery.

[0051] Example 2

[0052] Based on the above embodiment 1, the battery pack 11 is packaged with supporting components to form this embodiment. The first housing 1 is also recessed with a handle groove 106 and a power tool body groove 107. The handle groove 106 holds the handle of the power tool, and the power tool body groove 107 holds the main body of the power tool.

[0053] By increasing packaging space to aseptically package the handle and body of power tools, and assembling them together when in use, the risk of infection is reduced.

[0054] Example 3

[0055] The difference from Embodiment 1 is that the battery device in this embodiment is specifically an integrated power tool, with a recessed groove 105 formed on the first housing 1 to hold the integrated power tool. That is, the sterile packaging rechargeable kit for medical power tools of this invention can also directly charge the battery carried by the integrated power tool itself.

[0056] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0057] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
