[0028] Embodiment one:

[0030] Specifically, to be able to realize the type identification and state marking of catheter, catheter side interface 22 can quickly identify and classify catheter model by movably connected with the equipment side interface 13, determine whether catheter is used, mark catheter after use, and the embodiment is movably connected by equipment body 1 and catheter body 2, and the electrical characteristics of equipment body 1 identification catheter body 2 realizes catheter type identification 121, and equipment body 1 changes the electrical characteristics of catheter body 2 and realizes catheter state marking 122.The control module 11 and functional module 12 include the main chip of system, the control module 11 is used to send instruction to the functional module 12, the functional module 12 is used to execute state switching, type identification 121 and state marking 122 function.

[0031] As a preferred embodiment of the embodiment, the functional module 12 includes type identification 121 and state marking 122, and the type identification 121 is used to realize the function of the first state;The state marking 122 is used to realize the function of the second state.

[0032] As a preferred embodiment of the embodiment, the catheter side interface 22 includes one or more feature channels;The equipment side interface 13 includes one or more channels matched with the position, number and interface characteristics of the feature channel.

[0033] As a preferred embodiment of the embodiment, the circuit characteristics of the catheter capable of type identification and state marking include: a plurality of the feature channels are connected in parallel;The functional module 12 is located in the main line of a plurality of the feature channels;Type identification 121 and state marking 122 are connected in parallel, and the switch and switching of the first state and second state are realized by double-pole switch.

[0034] Specifically, as shown in Figure 2 The parallel structure of the feature channels in the catheter-side interface 22 can ensure that, after the electrical characteristics of one of the marker channels change (such as open circuit, approximate short circuit), the other feature channels can still show electrical characteristics after being powered on. The function module 12 needs to switch the functions of all the marker channels as a whole, and is therefore connected in series with the feature channels, which are arranged on the main circuit of the marker channels.

[0035] As a preferred embodiment of the present embodiment, a single feature channel has one of a plurality of rated electrical characteristics, which refers to the total resistance characteristics of the electronic element, and rated refers to a plurality of discrete and limited electrical characteristics.

[0036] As a preferred embodiment of the present embodiment, the feature channel includes at least one marker channel.

[0037] As a preferred embodiment of the present embodiment, the electrical characteristics of the marker channel are one of two rated electrical characteristics, which can be changed based on the state of the catheter of the one type identification and state marking.

[0038] As a preferred embodiment of the present embodiment, the electrical characteristics of the marker channel can only be changed once.

[0039] Specifically, as a combination of a plurality of preferred embodiments, the catheter of the one type identification and state marking of the present embodiment can achieve the effect that the marker channel can irreversibly change the electrical characteristics after the catheter is used, and different electrical characteristics can be obtained when reading the electrical characteristics of the catheter before and after use, and the catheter before and after use can be distinguished by identifying the characteristics of the marker channel.

[0040] In terms of the circuit of the marker channel, the marker channel has a fuse structure, and by applying a specific current for a certain length of time to the fuse, the fuse is fused, and the electrical characteristics of the current marker channel are considered as an approximate open circuit, and the voltage and current characteristics after the type identification 121 are changed.

[0041] In terms of the state marking 122 of the marker channel, the following steps are implemented:

[0042] AS1: The device-side interface 13 is connected to the catheter-side interface 22, and a loop is formed;

[0043] AS2: The control module 11 adjusts the function module 12 to enter the second state;

[0044] AS3: The control module 11 performs the type identification 121 step to identify the marker channel;

[0045] AS4: the function module 12 fuses the mark channel;

[0046] AS5: the control module 11 identifies the state of the mark channel again, and performs subsequent operations according to the state of the mark channel.

[0047] As a preferred embodiment of the present embodiment, the circuit characteristics of the catheter capable of type identification and state marking include: a plurality of feature channels are connected in parallel; the function module 12 is located in the trunk of a plurality of feature channels; the type identification 121 and the state marking 122 are connected in parallel, and the switching of the first state and the second state is realized by a double-throw switch.

[0048] In summary, the present application realizes readable coding by using the electrical characteristics of the circuit, and the catheter setting structure is relatively simple. Compared with the prior art using a chip to read storage, the present application significantly saves costs, and the circuit structure is simple and expandable. By connecting the device-side interface 13 and the catheter-side interface 22 to form a loop, the control module 11 can read the electrical characteristics (such as current and voltage) of the device-side interface 13. The electrical characteristics are preferably set as the coding of the catheter model. The catheter-side interfaces 22 of the same catheter model have the same initial electrical characteristics, and the catheter-side interfaces 22 of different catheter models are differentiated. Then, the control module 11 can read the model of the catheter according to the electrical characteristics. In order to provide a scheme for marking the use state of the catheter and avoid the malicious repeated use of the catheter, causing medical hazards, the control module 11 queries the mark channel in the catheter-side interface 22, and performs irreversible marking on the inside of the mark channel by the outside, so as to eliminate the possibility of reusing the used catheter. The irreversible marking refers to performing a specific marking step, and the marking step causes the characteristics of the mark channel to change and cannot be repaired. Preferably, through creative design, the common circuit design idea based on protecting the circuit is broken, and the present embodiment realizes irreversible marking by damaging the electrical characteristics of the circuit. By utilizing the asymmetry of damage-repair at the physical level, a permanent marking is realized, which has significant advantages.

[0049] The type recognition 121 mode specifically obtains voltage values of different characteristic channels after power-on, which are called levels. In the production of catheters, voltage codes of different types of catheters are planned, an encoding table is obtained, and the read voltage code is looked up in the encoding table to find the corresponding catheter type. By changing the radix, the embodiment can adapt to a larger number of catheter types. The change of radix refers to finer division of the level between 0V and the working voltage to expand the upper limit of the number of codes. Specifically, when the characteristic channel is 2 and the level is 2, the high level represents the code number 1 and the low level represents the code number 0. Through the binary combination of 0 and 1 in two characteristic channels, 2-bit binary can be formed, and there are four codes 00, 01, 10 and 11 in total. When the catheter type is more than four, increasing the number of characteristic channels can increase the total number of codes. However, increasing the number of characteristic channels will also increase the cost, and it is not easy to think that the level is divided into three, i.e. high level, medium level and low level, which is equivalent to converting binary to ternary, resulting in 00, 01, 02, 10, 11, 12, 20, 21 and 22 in total. On the one hand, by changing the radix, the number of codes can be increased by using at least two characteristic channels, thereby maximizing cost savings. On the other hand, the change of radix combined with the increase of the number of characteristic channels can exponentially increase the number of codes, solving the problem of the number of codes.
