Therefore, they should not be construed as limitations on the embodiments of this application.

[0034] In order to better understand the above-mentioned objectives, technical solutions and advantages of this application, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings, and to understand in detail how to solve the problems raised in the background art.

[0035] like Figures 2 to 8 As shown, an adapter for a monitor includes a housing 1, which covers a plug 2, a connector 5, and a socket 6 connected in sequence. The front end of the plug 2 is provided with two rows of upper and lower connecting holes 21, and the rear end of the plug 2 is provided with two rows of spring contacts 3 corresponding to the connecting holes 21, as well as two skeletons 4 for limiting and fixing the spring contacts 3. The skeletons 4 are engaged with the plug 2.

[0036] Through the above scheme, the outer shell 1 is molded in-mold to cover the plug 2, connector 5 and socket 6 to form an integrated structure. The plug 2, connector 5 and socket 6 are all plastic parts to ensure structural strength. At the same time, corresponding connecting holes 21 and spring pieces 3 are respectively set at the front and rear ends of the plug 2. The frame 4 abuts against the spring piece 3 installed in the plug 2, and the frame 4 is snapped into the plug 2 to fix the spring piece 3. When the adapter is inserted or pulled out from the monitor's connector, the protruding pin contacts or disconnects from the spring piece 3, causing the spring piece 3 to undergo elastic deformation or rebound movement. The structure and manufacturing process of the spring piece 3 are simple, and it has good elasticity, conductivity and solderability. The production cost is low and meets the requirements for disposable wrapping.

[0037] In this embodiment, the connector 5 is a cavity structure with openings on both sides, which enables it to snap into the plug 2 and the socket 6. The cavity of the connector 5 contains multiple lead wires. The front end of the lead wires is welded and fixed to the tail end of the spring 3, and the rear end of the lead wires is connected to the socket 6. The socket 6 is provided with a plug hole for insertion, so that ECG signals and blood oxygen signals can be transmitted after connection. There are 21 springs 3, which are made of metal with good elasticity. They are shaped by bending and other processes, and then the surface is electroplated to give them good conductivity, solderability and aesthetics. The metal springs 3 have stable elasticity, consistency and repeatability and are not easy to decay. During installation, multiple springs 3 are first installed in sequence to the corresponding positions of the plug 2 to form a two-row plug structure. Then, two frames 4 are installed in the designated positions, the plug 2 and the frames 4 snap into each other, and the frames 4 abut against the springs 3. Then, the lead wires are welded to the springs 3. Next, the connector 5 and the socket 6 are installed in sequence. Finally, the outer shell 1 is formed by injection molding.

[0038] like Figure 3 and Figure 4 As shown, in one specific embodiment of the improvement, the plug 2 has a cavity 28 and a V-shaped isolation arm 23 is provided in the cavity 28. An isolation beam 25 is connected to the center of the back side of the isolation arm 23, so that the cavity 28 at the rear end of the plug 2 forms a double-layer structure for installing the spring 3 and the skeleton 4. The connection hole 21 is provided in the isolation arm 23. Specifically, the isolation arm 23 divides the cavity 28 into front and rear parts. The front opening is used for insertion with the monitor connector, and the rear end is used for installing the spring 3 and the frame 4. The opening of the isolation arm 23 faces the end connected to the monitor connector. The connection hole 21 corresponds to the protrusion of the connector. The isolation beam 25 is horizontally arranged to support and place the spring 3. Two rows of springs 3 are installed above and below the isolation beam 25 and are mirrored based on the isolation beam 25, so that when installing the spring 3, it is only necessary to insert it against the isolation beam 25, which is convenient for operation. However, it should be noted that the spacing between adjacent springs 3 can be set according to the requirements, that is, designed according to the arrangement of the protrusion of the monitor and the connection hole 21. For example, in this embodiment, the upper layer has 8 springs 3 evenly distributed, and the lower left and right sides have 4 and 9 springs 3 evenly distributed, respectively. At this time, the connection hole 21 connects the front and rear cavities 28 formed by the isolation arm 23. When inserting, the protrusion passes through the connection hole 21 and contacts the spring 3 to conduct electricity.

[0039] like Figure 5As shown, in one specific embodiment of the improvement, the plug 2 has a first mounting groove 22 on the top inner wall, the isolation arm 23 has a receiving groove 24 connected to the connecting hole 21 on the upper part, and the isolation beam 25 has a second mounting groove 26 on the top surface. The first mounting groove 22, the receiving groove 24, and the second mounting groove 26 are connected in sequence to accommodate the spring piece 3. Specifically, the groove structure formed by the sequential connection of the first mounting groove 22, the receiving groove 24, and the second mounting groove 26 is adapted to the spring piece 3. Based on the isolation beam 25, a double-layer structure with two rows of spring pieces 3 mirrored installation is formed, so that the bottom inner wall of the plug 2 is also provided with the first mounting groove 22, the lower part of the isolation arm 23 is also provided with the receiving groove 24 connected to the connecting hole 21, and the bottom surface of the isolation beam 25 is also provided with the second mounting groove 26. That is, the lower layer is also provided with a groove structure formed by the three connected to each other for installing the spring piece 3. Among them, the receiving groove 24 is provided on the upper and lower walls of the isolation arm 23, which can limit the installed spring piece 3 and prevent the spring piece 3 from being misaligned and deviated when it rebounds. The number of the above groove structures is the same as the number of spring pieces 3, which is conducive to the rapid installation of the spring piece 3.

[0040] like Figures 4 to 6 As shown, in one specific embodiment of the improvement, the spring 3 includes a snap-fit ​​section 31, a first bending section 32, a second bending section 33 and an abutment section 34 connected in sequence. The abutment section 34 is accommodated in the receiving groove 24. The first bending section 32 abuts against the frame 4. The second bending section 33 snaps into the first mounting groove 22. The snap-fit ​​section 31 snaps into the second mounting groove 26. Specifically, the snap-fit ​​section 31, the first bending section 32, and the second bending section 33 are connected vertically in sequence. The abutment section 34 bends downward and approaches the first bending section 32, but there is a gap between the abutment section 34 and the first bending section 32, so that the abutment section 34 has enough room to move when it comes into contact with the monitor's protruding needle and undergoes elastic deformation. The width of both the snap-fit ​​section 31 and the second bending section 33 is greater than that of the first bending section 32, and the snap-fit ​​section 31 is parallel to the isolation beam 25 to ensure that the spring piece 3 is placed stably on the isolation beam 25. After the spring piece 3 is installed, the frame 4 is inserted so that the first bending sections 32 of multiple spring pieces 3 are all held in place by the frame 4, ensuring the stability and uniformity of the spring piece 3 installation.

[0041] like Figures 4 to 6As shown, in one specific embodiment of the improvement, both the snap-fit ​​section 31 and the second bending section 33 are provided with side wings 35 extending to both sides. Correspondingly, both the first mounting groove 22 and the second mounting groove 26 are T-shaped structures. Specifically, the side wings 35 of the snap-fit ​​section 31 are multiple protrusions on both sides with decreasing thickness, which are arranged along the length of the snap-fit ​​section 31. The side wings 35 of the second bending section 33 are two rectangular segments on both sides extending outward, which have the same thickness as the second bending section 33. Meanwhile, the first mounting groove 22 has a T-shaped cross-section when viewed from the front, and the second mounting groove 26 has a T-shaped cross-section when viewed from above. However, the front end of the second mounting groove 26 has a connected groove for accommodating the first bending section 32. Based on this, when installing the spring clip 3, the snap-fit ​​section 31 is aligned with the second mounting groove 26, and the second bending section 33 is aligned with the first mounting groove 22 and pushed in until fully embedded. This allows the side wings 35 to be accommodated in the T-shaped structure and the abutment section 34 to be accommodated in the receiving groove 24, improving the initial vertical and horizontal positioning of the spring clip 3 during installation, which is beneficial for the rapid and stable installation of the spring clip 3.

[0042] like Figures 4 to 6 As shown, in one specific embodiment of the improvement, the receiving groove 24 and the abutment section 34 are inclined in the same direction so that the abutment section 34 fits against the isolation arm 23. Specifically, based on the V-shaped structure of the isolation arm 23 and the mirror-mounted upper and lower rows of spring pieces 3, the upper and lower receiving grooves 24 are inclined downward and inclined upward respectively. After the abutment section 34 is received in the receiving groove 24, it is ensured that the abutment section 34 fits against the wall of the isolation arm 23, which facilitates the contact between the abutment section 34 and the protruding needle of the monitor. It should be noted that the position of the connecting hole 21 corresponds to the front end of the abutment section 34 to prevent the abutment section 34 from being unable to bend or bending too much and breaking quickly when it contacts the protruding needle, thus ensuring the service life of the spring piece 3.

[0043] like Figure 4 and Figure 7 As shown, in one specific embodiment of the improvement, the bottom surface of the frame 4 is provided with a plurality of first protrusions 41 spaced apart. The first protrusions 41 are embedded in the second mounting groove 26 so that the first protrusions 41 are pressed against the snap-fit ​​section 31. Specifically, there is a groove between adjacent first protrusions 41, and protruding walls are formed on both sides of the second mounting groove 26. During installation, the first protrusions 41 are embedded in the second mounting groove 26, that is, the first protrusions 41 are attached to the upper surface of the snap-fit ​​section 31, and the grooves and protruding walls are engaged. Then, the frame 4 is pushed into the plug 2 in a straight line, which improves the stability and firmness of the spring piece 3 installation.

[0044] like Figure 4 and Figure 8As shown, in one specific embodiment of the improvement, the frame 4 is provided with a plurality of spaced-apart limiting grooves 42 and a second protrusion 43 disposed within the limiting grooves 42. The limiting grooves 42 correspond to the first bending section 32 so that the second protrusion 43 abuts against the first bending section 32. Specifically, an isolation wall is designed between adjacent limiting grooves 42. This isolation wall can prevent the spring piece 3 from deviating to the left or right. When the frame 4 is inserted into the plug 2 through the first protrusion engaging section 31, the first bending section 32 abuts against the surface of the second protrusion 43, so that the frame 4 abuts against the spring piece 3, preventing the spring piece 3 from shifting back and forth, and further providing stability and firmness for the installation of the spring piece 3.

[0045] like Figure 4 and Figure 8 As shown, in one specific embodiment of the improvement, the top surface of the frame 4 is provided with a locking block 44, and the top surface of the locking block 44 is provided with a slope 45. Correspondingly, the rear end of the plug 2 is provided with a locking slot 27, and the locking block 44 is embedded in the locking slot 27. Specifically, the bottom and top surfaces of the rear end of the plug 2 are provided with locking slots 27, which penetrate through the outer wall of the plug 2, that is, the locking slot 27 communicates with the cavity 28. There are two frames 4, which are also mirror-mounted. The slope design makes the thickness of the locking block 44 gradually decrease, and the thickness of the locking block 44 facing the plug 2 is the smallest. The locking block 44 can be smoothly embedded in the locking slot 27 through the slope, realizing the locking of the frame 4 and the plug 2, thereby forming a fixing structure for the spring piece 3 and ensuring the firmness of the spring piece 3 and the frame 4 installed on the plug 2.

[0046] Based on the adapter described above, the design of the connection hole 21 and the spring contact 3 on the plug 2 enables the adapter to be used with the device end (connector) of the IntelliVueMX40 monitor. By plugging other connectors into the socket 6, the connection between the monitor and the human body is completed, improving the compatibility and adaptability of the monitor.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
