Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical treatment, in particular to a treatment head detection device. Background Art
[0002] Treatment heads that match treatment equipment come in a variety of sizes and specifications, and different sizes and specifications of treatment heads need to be selected for different patients or treatment situations in order to achieve the best treatment effect.
[0003] The treatment device does not have the ability to automatically identify the size and specifications of the treatment head. This results in the treatment device being unable to determine whether the current treatment head is suitable for the treatment situation, resulting in the use of the wrong treatment head for the patient and poor treatment results.
[0004] Furthermore, treatment heads typically correspond to a fixed set of treatment parameters. Current treatment devices cannot automatically identify the size of treatment heads and therefore cannot automatically set the appropriate treatment parameters for the head. The therapist still needs to set these parameters, making the entire process complex and error-prone, impacting treatment effectiveness. Summary of the Invention
[0005] The utility model aims to provide a treatment head detection device to solve the problem.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] The treatment head detection device of the present invention comprises a detection ring and a treatment head, wherein the detection ring and the treatment head are clamped together via a positioning portion;
[0008] The detection ring includes a detection circuit;
[0009] The detection circuit includes a plurality of Hall switches, a straight pin connector, an inverter, a protection circuit, a capacitor, and a resistor;
[0010] The Hall switch is arranged on the detection ring; the Hall switch is connected to the capacitor and the inverter; the inverter is connected to the protection circuit and the straight pin connector respectively through a resistor; the straight pin connector is connected to the CPU circuit board of the treatment instrument;
[0011] A plurality of small magnets are arranged at the base of the treatment head at positions corresponding to the Hall switch.
[0012] Furthermore, the number of the Hall switches is greater than or equal to 2; and the number of small magnets greater than or equal to 1 and less than or equal to the total number of Hall switches is set at the root of the treatment head according to the model of the treatment head.
[0013] Furthermore, after the treatment head is connected to the detection ring, the Hall switch corresponding to the small magnet in the treatment head outputs a low level, which is inverted by the inverter and input into the treatment instrument through the straight pin connector.
[0014] Furthermore, the therapeutic instrument determines the model of the therapeutic head according to the number of input signals.
[0015] Furthermore, the output voltage of the Hall switch is 12V. When the treatment head is connected to the detection ring, the output voltage of the Hall switch corresponding to the small magnet in the treatment head is lower than 0.02V, which is reversed into a 12V voltage through the inverter and input into the treatment instrument.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] like Figure 1 、 Figure 2 As shown, the treatment head detection device of the present invention includes a detection ring 1 and a treatment head 4. The detection ring 1 and the base of the treatment head 4 are secured together via a positioning portion 3. Specifically, the treatment head 4 passes through the detection ring 1, and the positioning portion 3 on the detection ring 1 engages with the base of the treatment head 4, securing the two.
[0024] like Figure 3As shown, the detection ring 1 primarily comprises a detection circuit. This circuit includes several Hall switches 2, straight pin connectors, an inverter, a protection circuit, resistors, capacitors, and the like. The Hall switches 2 are arranged on the detection ring 1. Each Hall switch 2 is connected to an inverter. The inverter is then connected to the protection circuit and straight pin connectors via resistors. The straight pin connectors are connected to the CPU circuit board of the therapeutic device.
[0025] The base of the treatment head 4 is provided with a number of small magnets 5 corresponding to the placement of the Hall switches on the detection ring. In the present invention, the detection ring is provided with four Hall switches 2. The Hall switches 2 are evenly distributed on the detection ring 1. Depending on the model of the treatment head 4, a varying number of small magnets 5 can be provided at the base of the treatment head 4, from one to four. That is, the base of the treatment head 4 is provided with at least one and no more than four small magnets 5, depending on the model of the treatment head 4. Based on the combination of the placement of the small magnets 5, 15 different models of treatment heads can be identified.
[0026] When the treatment head 4 passes through the detection ring 1 and is fixed to the detection ring 1 , the small magnet 5 in the treatment head 4 approaches the Hall switch 2 on the detection ring 1 .
[0027] When no small magnet 5 approaches the Hall switch 2 on the detection ring 1, the switch is effectively disconnected, outputting a high voltage of 12V. When the small magnet 5 on the treatment head 4 approaches the Hall switch 2 on the detection ring 1, the switch is effectively turned on, outputting a low voltage below 0.02V. The output voltage is then reversed by an inverter, converting the low voltage below 0.02V back to a high voltage of 12V. This voltage is then input into the treatment device's CPU via a straight pin connector. The device then determines the model of treatment head 4 based on the number of input signals.
[0028] The number and position of the small magnets 5 embedded at the base of different treatment heads 4 are different. Some treatment heads 4 have one small magnet 5 embedded at the base, and the position of the embedded small magnet can be adjusted according to the position of the Hall switch.
[0029] Some treatment heads 4 have two small magnets 5 embedded at their bases, and according to the position of the Hall switch, the two small magnets 5 can be positioned in a combination, thereby being able to identify treatment heads 4 of various models.
[0030] Some treatment heads 4 have three small magnets 5 embedded at their bases, and the positions of the three small magnets 5 are combined according to the position of the Hall switch to identify various types of treatment heads 4. A treatment head 4 can have up to four small magnets 5 embedded in it.
[0031] If there's only one small magnet 5 at the base of treatment head 4, only one Hall switch 2 will output a low level, resulting in the treatment device receiving only one high-level signal. Based on the number of high-level signals received and the source of the high-level signal (i.e., the Hall switch position), the treatment device can display the model and specifications of the currently used treatment head 4 and the corresponding treatment parameters to the operator on its display.
[0032] When there are two small magnets 5 at the base of the treatment head 4, two Hall switches 2 will output a low level, and finally the treatment instrument can only receive two high-level signals. The treatment instrument displays the model and specifications of the treatment head 4 currently in use and the corresponding treatment parameters to the operator through the display screen of the treatment instrument based on the number of high-level signals received and the source of the high-level signals (i.e., the Hall switches at that position).
[0033] When there are three small magnets 5 at the base of the treatment head 4, three Hall switches 2 will output a low level, and the treatment instrument will only receive three high-level signals. Based on the number of high-level signals received and the source of the high-level signals (i.e., the Hall switches at that position), the model and specifications of the treatment head 4 currently in use and the corresponding treatment parameters can be displayed to the operator through the display screen of the treatment instrument.
[0034] When there are four small magnets 5 at the base of the treatment head 4, four Hall switches 2 will output a low level, and finally the treatment instrument can only receive four high-level signals. Based on the number of high-level signals received and the source of the high-level signals (i.e., the Hall switch at that position), the model and specifications of the treatment head 4 currently in use and the corresponding treatment parameters can be displayed to the operator through the display screen of the treatment instrument.
[0035] The protection circuit in this invention is a power management chip, used to protect sensitive input circuits from overvoltage. Specifically, the power management chip used in this invention is the SP721AG. The inverter used in this invention is the CD40106BM, capable of inverting and amplifying the output of a 5-12V high-level voltage. The straight pin connector in this invention uses a 1.25mm 6-pin connector, depending on the current state of the connected therapeutic device.
[0036] like Figure 4Figure 2 shows a circuit wiring diagram for the treatment head detection device of the present invention. The IN ports of the first Hall switch 6, the second Hall switch 7, the third Hall switch 8, and the fourth Hall switch 9 are connected to one end of capacitors C1, C2, C3, and C4, respectively. The other ends of capacitors C1, C2, C3, and C4 and the GND terminals of the first Hall switch 6, the second Hall switch 7, the third Hall switch 8, and the fourth Hall switch 9 are grounded. The OUT ports of the first Hall switch 6, the second Hall switch 7, the third Hall switch 8, and the fourth Hall switch 9 are connected to resistors R1, R2, R3, and R4, respectively, and are also connected to one end of the first inverter 10, the second inverter 11, the third inverter 12, and the fourth inverter 13 (CD40106BM). The other ends of the CD40106BM in inverters 10, 11, 12, 13, and 13 are connected to pins 3, 5, 2, and 1 of the power management chip SP721AG through resistors R5, R6, R7, and R8, respectively. They are also connected to pins 2, 1, 3, and 4 of a 1.25mm 6-pin connector, respectively. Pin 5 of the 1.25mm 6-pin connector is connected to the 12V power supply, and pin 6 is grounded. Pin 8 of the power management chip SP721AG is connected to the 12V power supply, pin 4 is grounded, and pins 6 and 7 are unused.
