[0001] The utility model relates to the technical field of transmission wire harnesses, in particular to a transmission wire harness for medical sensors. Background Art
[0002] A transmission wire harness for medical sensors is a wire harness system used to connect medical sensors and monitoring devices. Such a wire harness usually includes multiple cables or wires for transmitting physiological signals (such as electrocardiogram signals, blood oxygen saturation, etc.) acquired by the sensor to the monitoring device for monitoring, recording, or analysis. However, in traditional transmission wire harnesses for medical sensors, there are large assembly gaps between the sensor and the wire harness, and between the wire harness and the medical device. In a high-temperature and vibration environment, it is easy to cause problems such as displacement of the sensor, decreased accuracy, and non-operation. Content of the Utility Model

[0005] It includes a sheath. The sheath includes a first connecting sleeve and a second connecting sleeve. Both the first connecting sleeve and the second connecting sleeve are arranged in a frustum shape. The large-end of the second connecting sleeve is connected to the small-end of the first connecting sleeve. An installation hole is arranged along the axis of the sheath inside the sheath. A sensor is fixedly arranged in the installation hole. One end of the sensor extends outside the sheath. A wire is arranged on the sheath. The wire extends into the installation hole and is electrically connected to the sensor.
[0006] Preferably, a plug-in block is arranged at one end of the sensor close to the sheath. The plug-in block is in plug-in fit with the installation hole.
[0007] Preferably, a sealant layer is arranged between the sensor and the installation hole.
[0008] Preferably, a hardware terminal is arranged at one end of the wire away from the sheath.
[0009] Preferably, a threaded cap is sleeved on the wire.
[0010] Preferably, a plurality of convex ribs are circumferentially and spacedly arranged on the outer peripheral surface of the threaded cap.
[0011] Preferably, a Teflon heat shrinkable tube is sleeved on the wire.
[0012] Preferably, a positioning groove is arranged on the outer side surface of the first connecting sleeve.
[0013] Preferably, the sheath is made of medical-grade silicone material.
[0014] In summary, the present utility model includes at least one of the following beneficial technical effects:
[0015] After the sheath is installed on the device, the frustum-shaped sheath can be more firmly fixed after being inserted into the device. At the same time, after the sealing glue layer is filled between the sensor and the sheath, the assembly gap is small, the assembly is firm, and the thread cap is connected to the device to fix the wire harness. In this way, problems such as the displacement of the sensor, the decrease in accuracy, and the non-operation are not likely to occur in a high-temperature vibration environment.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.
[0021] The embodiments of the present utility model disclose a transmission wire harness for a medical sensor 2, such as Figure 1-2As shown in the figure, it includes a sheath 1. The sheath 1 includes a first connecting sleeve 11 and a second connecting sleeve 12. Both the first connecting sleeve 11 and the second connecting sleeve 12 are arranged in a frustum shape. The large-head end of the second connecting sleeve 12 is integrally connected to the small-head end of the first connecting sleeve 11. In this way, when the sheath 1 is installed on the device, the frustum-shaped sheath 1 can be more firmly fixed after being inserted into the device. In addition, a positioning groove 14 is formed on the outer side surface of the first connecting sleeve 11, and the positioning groove 14 can facilitate the positioning between the sheath 1 and the device, improving the assembly accuracy. At the same time, the sheath 1 is made of medical-grade silicone material, and the medical-grade silicone material is safer.
[0022] In addition, an installation hole 13 is formed in the sheath 1. The installation hole 13 is arranged along the axis of the sheath 1. One end of the installation hole 13 penetrates through the small-head end of the second connecting sleeve 12. An inductor 2 is fixedly arranged in the installation hole 13. A plug-in block 21 is fixedly arranged at one end of the inductor 2 close to the sheath 1. The plug-in block 21 is in plug-in fit with the installation hole 13, and one end of the inductor 2 extends outside the sheath 1. At the same time, a sealant layer is arranged between the inductor 2 and the installation hole 13, and the sealant layer is of medical grade. After the sealant layer is filled into the installation hole 13, the inductor 2 is assembled into the installation hole 13. After the sealant layer solidifies, the inductor 2 and the sheath 1 can be firmly fixed together. The assembly gap between the inductor 2 and the sheath 1 is small, and the assembly is firm.
[0023] In addition, two wires 3 are arranged on the sheath 1. The colors of the two wires 3 are white and green respectively, so that they can be better distinguished. One end of the wire 3 passes through the large-head end of the first connecting sleeve 11 and extends into the installation hole 13, and the wire 3 is electrically connected to the inductor 2. At the same time, a hardware terminal 4 is fixedly connected to the end of the wire 3 far from the sheath 1. The hardware terminal 4 can facilitate the plugging of the wire harness on the device. In addition, a threaded cap 5 is fixedly sleeved on the wire 3. The threaded cap 5 is screwed onto the device to fix the wire harness. In addition, a plurality of convex ribs 51 are integrally formed at circumferential intervals on the outer peripheral surface of the threaded cap 5. The convex ribs 51 can increase the friction when a person rotates the threaded cap 5 and are not easy to slip. In addition, a Teflon heat shrinkable tube 31 is sleeved on the wire 3. The Teflon heat shrinkable tube 31 has good stability, can not only protect the wire 3, but also is more hygienic and safe.
[0024] The implementation principle of the medical inductor 2 transmission wire harness in the embodiment of the present utility model is as follows: The sheath 1 is installed on the device. The frustum-shaped sheath 1 can be more firmly fixed after being inserted into the device. At the same time, after the sealant layer is filled between the inductor 2 and the sheath 1, the assembly gap is small and the assembly is firm. The threaded cap 5 is connected to the device to fix the wire harness. In this way, problems such as the sensor being displaced, the accuracy decreasing, and not working are not likely to occur in a high-temperature and vibrating environment.
