[0001] This utility model relates to the field of medical device technology, and in particular to a medical heating blanket. Background Technology

[0002] Medical heating blankets are essential devices used in medical settings to maintain patient body temperature and prevent hypothermia. In traditional medical heating blanket designs, the connection between the main unit and the heating blanket is typically achieved through a connecting pipe. To further ensure connection stability, a protruding connector is often located on the main unit's outer casing. However, because this connector protrudes from the casing, users can easily bump into it during use, leading to loosening, damage, or even detachment of the connection, thus affecting the normal operation of the heating blanket. Utility Model Content

[0003] The main purpose of this utility model is to propose a medical heating blanket, which aims to solve the technical problem in related technologies where the connecting joint protrudes from the main unit shell, thus affecting the normal operation of the heating blanket.

[0004] To achieve the above objectives, the present invention provides a medical heating blanket, which includes:

[0005] Electric blankets;

[0006] The host computer has a housing, and a cavity is formed inside the housing;

[0007] A connecting connector is housed within the cavity. One end of the connecting connector passes through the inner wall of the cavity for electrical connection with the circuitry inside the main unit, and the other end of the connecting connector passes through the outer shell for electrical connection with the electric blanket.

[0008] In one embodiment, the outer shell is further provided with a first through hole, which communicates with the cavity, and one end of the connecting joint passes through the side wall of the cavity and is exposed outside the first through hole.

[0009] In one embodiment, the cavity has a notch that penetrates one side wall, and the outer shell also has a first through hole that communicates with the cavity. The opening direction of the notch intersects with the opening direction of the first through hole.

[0010] In one embodiment, the opening direction of the first through hole intersects with the direction in which the connecting joint passes through the cavity.

[0011] In one embodiment, the connecting joint includes a connector and a connecting tube, the connector being sleeved on the outside of the connecting tube and connected to the connecting tube, and the connector being connected to the inner wall of the cavity.

[0012] In one embodiment, the inner wall of the cavity is provided with a second through hole, and the connector is snapped into the second through hole.

[0013] In one embodiment, the connector has a first connecting segment and a second connecting segment. The inner peripheral wall of the first connecting segment is provided with an internal thread, and the outer peripheral wall of the second connecting segment is provided with an external thread. The end of the second connecting segment near the first connecting segment forms an abutment end. The internal thread is screwed into the external thread, and the abutment end abuts against the periphery of the second through hole.

[0014] In one embodiment, the end of the second connecting segment furthest from the first connecting segment is tapered.

[0015] In one embodiment, the cavity contains two connecting joints spaced apart, one end of each connecting joint passing through the inner wall of the cavity, and the other end of each connecting joint passing through the outer shell and electrically connected to the electric blanket.

[0016] The technical solution of this utility model involves designing the connecting connector to be embedded inside the main unit, completely housed within the cavity of the main unit's outer casing. One end of the connector passes through the inner wall of the outer casing cavity and connects to the internal circuitry of the main unit, while the other end passes through the outer casing and connects to the electrical connection portion of the electric blanket. This design utilizes the structure of the main unit's outer casing cavity, concealing the connecting connector within the main unit, ensuring the reliability of the electrical connection while avoiding various problems that might arise from protruding external parts. This arrangement, by integrating the connecting connector into the cavity of the main unit's outer casing, achieves concealment of the connection portion, significantly improving the overall aesthetics of the medical heating blanket. It also avoids the problem of protruding plastic parts being easily affected by external interference and damage during use, enhancing the stability and reliability of the device. Furthermore, the concealed connection method optimizes the installation space of the main unit, making it more suitable for use in limited medical environments, improving the practicality and ease of operation of the device.

[0029] This utility model proposes a medical heating blanket 100.

[0030] Please see Figures 1 to 5 In one embodiment of the present invention, the medical heating blanket 100 includes an electric heating blanket, a main unit 1, and a connecting connector 2. The main unit 1 has a shell 11, and a cavity 111 is formed inside the shell 11. The connecting connector 2 is accommodated in the cavity 111. One end of the connecting connector 2 passes through the inner wall of the cavity 111 and is used for electrical connection with the circuit inside the main unit 1. The other end of the connecting connector 2 passes through the shell 11 and is electrically connected with the electric heating blanket.

[0031] In this embodiment, the medical heating blanket 100 is typically electrically connected to the main unit 1 via a connector 2. To further ensure connection stability, a protruding connector 21 is installed on the outer casing 11 of the main unit 1. However, because the connector 2 protrudes from the outer casing 11, users may accidentally touch the connector 21 during actual use, leading to loosening, damage, or even detachment of the connection, thus affecting the normal operation of the heating blanket. It should be noted that, in conjunction with... Figure 1 The outer casing 11 protects the internal circuitry and components of the main unit 1, preventing external dust and debris from entering. A cavity 111 within the casing 11 provides space for the installation and storage of the connector 2, and this cavity 111 communicates with the space containing the control circuit board within the casing 11. It is understood that the connector 2 serves as a bridge for electrical connection between the casing 11 and the electric blanket, and the wiring between the casing 11 and the electric blanket is located within the connector 2. Figure 3The connecting connector 2 includes a connector 21 and a connecting tube 22. The connecting connector 2 is housed within the cavity 111. One end of the connecting connector 2 is electrically connected to the circuitry within the main unit 1, and the other end passes through the outer casing 11 of the main unit 1 and is electrically connected to the electric blanket. One end of the connecting connector 2 is fixed to the inner wall of the cavity 111 by welding, riveting, or threaded connection to ensure the connection's strength and stability. In one embodiment, one end of the connecting connector 2 is designed with an external thread, and the inner wall of the cavity 111 is designed with a matching internal thread. The threaded connection securely fixes the connecting connector 2 to the inner wall of the cavity 111. In another embodiment, one end of the connecting connector 2 is designed with a snap-fit ​​structure, and the inner wall of the cavity 111 has a corresponding slot. The snap-fit ​​and slot engage to fix the connecting connector 2 to the inner wall of the cavity 111. In yet another embodiment, one end of the connecting connector 2 is fixed to the inner wall of the cavity 111 by crimping.

[0032] The technical solution of this utility model involves designing the connecting connector 2 to be embedded inside the main unit 1, completely housed within the cavity 111 of the main unit 1's outer shell 11. One end of the connecting connector 2 passes through the inner wall of the cavity 111 of the outer shell 11 and connects to the internal circuitry of the main unit 1, while the other end passes through the outer shell 11 and connects to the electrical connection portion of the electric blanket. This design utilizes the structure of the inner cavity of the main unit 1's outer shell 11, concealing the connecting connector 2 within the main unit 1, ensuring the reliability of the electrical connection while avoiding various problems that might arise from protruding external components. This arrangement, by integrating the connecting connector 2 into the cavity 111 of the main unit 1's outer shell 11, achieves concealment of the connection portion, significantly improving the overall aesthetics of the medical heating blanket 100. It also avoids the problem of protruding plastic parts being easily affected by external interference and damage during use, enhancing the stability and reliability of the device. Furthermore, the concealed connection method optimizes the installation space of the main unit 1, making it more suitable for use in limited medical environments, improving the device's practicality and ease of operation.

[0033] In one embodiment of the present invention, the outer shell 11 is further provided with a first through hole 112, which communicates with the cavity 111. One end of the connecting connector 2 passes through the side wall of the cavity 111 and is exposed outside the first through hole 112.

[0034] In this embodiment, the first through hole 112 provides a channel for the connector 2 from the inside of the main unit 1 to the outside, allowing the connector 2 to be smoothly electrically connected to the electric blanket. It should be noted that the size of the first through hole 112 is adapted to the size of the connector 2. The first through hole 112 penetrates through the outer shell 11 of the main unit 1 and one side wall of the cavity 111, with one end of the connector 2 precisely confined within the first through hole 112. The location of the first through hole 112 is not limited, and can be combined with... Figure 2The first through hole 112 is located at the bottom end of the housing 11 and connects to the device from the bottom via the connector 2, resulting in neater wiring and improved overall aesthetics of the host 1. The cross-sectional area of ​​the first through hole 112 gradually decreases from the end closer to the cavity 111 to the end farther away from the cavity 111. This arrangement makes the connection operation of the connector 2 more intuitive and convenient, reducing the complexity of installation and maintenance.

[0035] In one embodiment of the present invention, the cavity 111 has a notch 111a that penetrates one side wall of it, and the outer shell 11 also has a first through hole 112 that communicates with the cavity 111. The opening direction of the notch 111a and the opening direction of the first through hole 112 are intersecting.

[0036] In this embodiment, to enhance flexibility, the cavity 111 has a notch 111a extending through one side wall. It should be noted that the opening direction of the notch 111a does not overlap with the opening direction of the first through hole 112. The notch 111a facilitates easy handling of the connecting joint 2 by the operator. Combined with... Figure 2 , Figure 4 as well as Figure 5 It is understood that the notch 111a is located at the bottom of the housing 11 of the main unit 1 and is not exposed on the outer side wall of the main unit 1. The intersection of the notch 111a and the first through hole 112 allows the connector 21 to have a certain range of angle adjustment during installation, making the installation operation more convenient and quick, and reducing the installation difficulty. In one embodiment, the connector 2 can be inserted through a side wall corresponding to the side wall where the first through hole 112 is located. In this case, the installation is more convenient, and the notch 111a is adjacent to the side wall through which the connector 2 is inserted, which is convenient for the operator to adjust. In another embodiment, the connector 2 can also be inserted through a side wall adjacent to the side wall where the first through hole 112 is located. The specific implementation method is described in the next embodiment.

[0037] In one embodiment of the present invention, the opening direction of the first through hole 112 is intersecting with the direction in which the connecting joint 2 passes through the cavity 111.

[0038] In this embodiment, combined with Figure 2 and Figure 3 It should be noted that the connecting joint 2 is installed on a side wall adjacent to the side wall where the first through hole 112 is located. This side wall is opposite to the side wall through which the notch 111a passes. This allows for better utilization of the internal space of other cavities and the cavity 111 of the outer casing 11, improving the space utilization rate inside the main unit 1 and reducing the overall volume. The above design, with the connecting joint 2 penetrating from the side wall opposite to the notch 111a, reduces the shaking or displacement of the connecting joint 2 due to external forces during use, thus enhancing the structural stability of the entire device.

[0039] In one embodiment of the present invention, the connecting joint 2 includes a connecting member 21 and a connecting pipe 22. The connecting member 21 is sleeved on the outside of the connecting pipe 22 and connected to the connecting pipe 22. The connecting member 21 is connected to the inner wall of the cavity 111.

[0040] In this embodiment, combined with Figure 3 The connecting pipe 22 is located inside the connector 21, and the connector 21 is sleeved on the outside of the connecting pipe 22, and is securely connected to the connecting pipe 22. This design makes the connecting joint 2 more compact in its overall structure, while ensuring the stability and reliability of the connection. Figure 3 It should be noted that the connector 21 has a third through hole, and the connecting tube 22 is confined within the third through hole. The end of the connector 21 away from the inner wall of the cavity 111 is tapered so that the connecting tube 22 can be confined within the connector 21. Here, the connector 21 and the connecting tube 22 can also be integrally formed.

[0041] In one embodiment of the present invention, a second through hole 111b is provided on the inner wall of the cavity 111, and the connector 21 is snapped into the second through hole 111b.

[0042] In this embodiment, combined with Figure 3 The inner wall of the cavity 111 is provided with a second through hole 111b, which is used to engage and limit the connector 21. It can be understood that the size and shape of the second through hole 111b are adapted to the shape of the connector 21 to ensure that the connector 21 can be firmly limited after insertion, and to prevent the connector 21 from shifting or loosening due to vibration or external force during use.

[0043] In one embodiment of the present invention, the connector 21 has a first connecting section 211 and a second connecting section 212. The inner peripheral wall of the first connecting section 211 is provided with an internal thread, and the outer peripheral wall of the second connecting section 212 is provided with an external thread. The end of the second connecting section 212 near the first connecting section 211 forms an abutment end 213, and the internal thread and the external thread are screwed together. The abutment end 213 abuts against the periphery of the second through hole 111b.

[0044] In this embodiment, combined with Figure 3It should be noted that the second connecting segment 212 passes through the inner wall of the cavity 111, and the first connecting segment 211 is sleeved on the outer side of the second connecting segment 212. The end of the second connecting segment 212 near the first connecting segment 211 forms an abutment end 213, which abuts against the periphery of the second through hole 111b. The outer peripheral wall of the second connecting segment 212 is provided with external threads, and the inner peripheral wall of the first connecting segment 211 is provided with internal threads, so that the connection between the connector 21 and the inner wall of the cavity 111 is stable. The above arrangement achieves the connection through the engagement of the internal threads of the first connecting segment 211 and the external threads of the second connecting segment 212. The thread engagement provides sufficient friction to prevent the connector 21 from loosening or falling off during use.

[0045] In one embodiment of the present invention, the end of the second connecting segment 212 that is away from the first connecting segment 211 is tapered.

[0046] In this embodiment, combined with Figure 3 It should be noted that the connecting pipe 22 is located inside the second connecting section 212, and the second connecting section 212 is sleeved on the outside of the connecting pipe 22. This tapered design causes the diameter of the second connecting section 212 to gradually decrease, forming a conical structure. The connecting pipe 22 is located inside the second connecting section 212, and the second connecting section 212 is sleeved on the outside of the connecting pipe 22 and firmly connected to it. This design not only improves the overall stability of the connecting joint 2, but also enhances its sealing performance and mechanical strength during use.

[0047] In one embodiment of the present invention, the cavity 111 contains two connecting joints 2 spaced apart. One end of each connecting joint 2 passes through the inner wall of the cavity 111, and the other end of each connecting joint 2 passes through the outer shell 11 and is electrically connected to the electric blanket.

[0048] In this embodiment, by providing two independent connection connectors 2, the redundancy of the system can be improved. The two independent connection connectors 2 can ensure that each connector is connected to the correct interface, and the two connection connectors 2 can share the current load, reduce the electrical stress on a single connector 21, and extend the service life of the equipment.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
