The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Referring to fig. 1 to 5, the present embodiment may be applied to a case of providing a medical instrument with an access mode of a temperature probe, and the apparatus specifically includes the following structure: adapter 100, temperature probe 200, control module 300.

The control module 300 may be integrated in the medical device, and both the adaptor 100 and the temperature probe 200 may be disposed outside the medical device as an external structure of the medical device.

The adapter 100 includes a first connector 110 and a second connector 120 electrically connected to each other. Specifically, when the temperature needs to be measured, the temperature probe 200 may be inserted into the first connector 110, and the second connector 120 may be inserted into the control module 300, so that the control module 300 obtains a temperature signal from the temperature probe 200, wherein the temperature signal is an analog signal. When temperature measurement is not required, the temperature probe 200 and adapter 100 can be removed from the control module 300, further reducing the bulk of the medical device in the external structure.

Illustratively, the first connector 110 of the adapter 100 is a TRS interface, and the second connector 120 is a Type-C connector.

The TRS interface is used for inserting a TRS terminal (TRS connector). The TRS terminal is a connector that is often used to connect audio equipment for the transfer of audio signals. TRS is an acronym for its three component parts: tip (Tip), Ring (Ring), Sleeve (Sleeve). Since such connectors are typically used for plugging in earphones and microphones, they are also called phone jacks (phoneJack). Although collectively referred to as TRS, it may also be referred to as TS (no ring, i.e., tip and sleeve each provide one contact), TRS (one ring, three contacts), TRRS (two rings, four contacts), etc., depending on the number of rings (R) of a particular plug/receptacle.

The Type-C connector, also called USB-C connector, is a hardware interface form of Universal Serial Bus (USB), and is characterized in that the top and bottom ends are completely consistent in appearance, and compared with Micro-USB, a user does not need to distinguish the front and back sides of the USB.

Further, TRS terminal and Type-C connect all to have small characteristics. That is, by using the adapter 100, the volume of the medical device in the external structure can be reduced. The plug 201 of the temperature probe 200 mates with the first connector 110 in the adapter 100 and may be inserted into the first connector 110.

Further, the control module 300 may be provided with a general interface for inserting the second connector 120, where the general interface may be a USB interface, a Type-C interface, or the like matched with the second connector 120.

In this embodiment, the first connector 110 in the adapter 100 is further provided with a detection structure 111, and the detection structure 111 is connected to the detection end 121 of the second connector 120.

In one embodiment, the sensing structure 111 is used to sense the insertion of the temperature probe 200 into the first connector 110 such that the sensing end 121 of the second connector 120 outputs an analog switching signal.

For example, when the first connector 110 is a TRS interface, symbols representing different components are usually combined together according to a specific interface structure in the circuit diagram due to various TRS interface structures. In this embodiment, the specific connection structure of the detection structure 111 is not limited. Further, taking the TRS interface shown in fig. 2 as an example for illustration, the temperature probe 200 can be inserted into the first connector 110 from right to left. Further, for the TRS interface shown in fig. 2, T and R are both relay structures. When the temperature probe 200 is not inserted, the contacts (numbered from top to bottom) 2-3 and 6-7 are conducted; on the contrary, when the temperature probe 200 is inserted, the spring is deformed by force, and 1-2 and 7-8 are respectively conducted. The rest 4 is connected with T, 5 is connected with R, and 9 is connected with S. That is, hardware, firmware, or even software can be assisted in determining whether the temperature probe 200 is inserted by the conduction of 1-2-3 and 6-7-8. That is, the detecting structure 111 in this embodiment may include a relay structure for determining whether the temperature probe 200 is inserted.

In yet another embodiment, the detecting structure 111 is used to make the detecting terminal 121 of the second connector 120 always output the analog switching signal, such as grounding the detecting terminal 121 of the second connector 120 to output the analog switching signal.

Further, the control module 300 is further provided with a channel selection terminal 301 connected to the detection terminal 121 to obtain the analog switching signal from the detection terminal 121.

In this embodiment, the control module 300 may be provided with a digital signal channel (not shown) and an analog signal channel (not shown); the digital signal channel and the analog signal channel can be correspondingly provided with at least one signal channel. Further, the digital signal channel and the analog signal channel may be provided with a common signal input 302, and the signal input 302 is electrically connected to the second connector 120 to obtain the temperature signal of the temperature probe 200.

Generally, the signal input from the signal input terminal 302 can be transmitted by using a digital signal channel and/or an analog signal channel. It should be noted that in the computer field, digital signals are generally processed. Unlike digital signals, when analog signals are processed, it is necessary to perform signal processing from analog to digital. That is, in the control module 300, an analog-to-digital conversion (a/D) module (not shown) is further disposed in the analog signal channel for converting the analog signal into a digital signal.

In this embodiment, since the temperature signal is an analog signal, the analog switching signal is output at the detection terminal 121; the control module 300 may enable the analog signal channel to transmit the temperature signal according to the analog switching signal obtained from the channel selection terminal 301.

In addition, the control module 300 may be provided with a general interface, which does not generate an analog conversion signal when accessing another type of connector or adapter that is not provided with the detection structure 111, and the control module 300 in this embodiment may use a digital signal channel to transmit the signal input from the signal input end 302. Therefore, the universal interface of the control module 300 in this embodiment can achieve the effect of one port for multiple purposes, thereby saving the development cost, and the switching of the signal channel is performed automatically, thereby increasing the convenience of use. For example, if the first connector 110 is a TRS interface and the second connector 120 is a Type-C connector, if the common interface of the control module 300 has access to a memory (e.g., a usb flash drive) of the Type-C connector, the memory does not have a corresponding TRS interface (provided with the detection structure 111), and therefore, the analog switching signal is not generated.

When the first connector 110 is a TRS jack, the first jack is a TRS jack, and the plug 201 is a TRS terminal. The plug 201 is provided with a first output end NTC + and a second output end NTC-, and both ends of the thermistor NTC _ R are electrically connected with the first output end NTC + and the second output end NTC-, respectively. The thermistor NTC _ R may be a negative temperature coefficient resistor, and the resistance value decreases with the increase of the temperature.
