[0034] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0035] The following Figures 1-5 describes the peristaltic pump for a thermal steam ablation device with built-in status monitoring according to the present utility model.

[0036] The peristaltic pump for a thermal steam ablation device with built-in status monitoring according to the present utility model includes a fixed seat 3, a pump head 1, a motor 2, a magnetic part 5 and a Hall sensor 6. The pump head 1 includes a body 11 and a movable part 12. The body 11 is installed on the fixed seat 3, and the movable part 12 is slidably arranged on the fixed seat 3. A clamping space 13 is formed between the body 11 and the movable part 12; the output end of the motor 2 is connected to the movable part 12 to drive the movable part 12 to slide on the fixed seat 3 to open or close the clamping space 13; the magnetic part 5 is installed on the movable part 12 and moves with the movable part 12; the Hall sensor 6 is arranged on the fixed seat 3. When the clamping space 13 is closed, the Hall sensor 6 is disposed opposite to the magnetic part 5. It should be noted that the magnetic part 5 is a magnet. Of course, the magnetic part 5 can also be a magnetic steel, an alnico magnetic steel, a samarium cobalt magnetic steel, a neodymium iron boron, a ferrite magnetic steel, a permanent magnet, a magnetic ring, a magnetic rod, etc., including various magnetic materials and products made therefrom.

[0037] The peristaltic pump for a thermal steam ablation device with built-in status monitoring provided by the present utility model installs the pump head 1 through the fixing seat 3. The moving part 12 of the pump head 1 moves relative to the main body 11, and the moving part 12 and the main body 11 form a clamping space 13 for clamping the delivery pipe 4. Among them, the motor 2 drives the moving part 12 to slide on the fixing seat 3 to open or close the clamping space 13, so that the liquid in the delivery pipe 4 flows along with the rotation of the motor 2. A magnetic part 5 is installed on the moving part 12. At the same time, a Hall sensor 6 is provided on the fixing seat 3. When the clamping space 13 is closed, the Hall sensor 6 is arranged opposite to the magnetic part 5. At this time, the Hall sensor 6 senses the magnetic field effect of the magnetic part 5 and feeds back through the device prompt that the peristaltic pump is in the closed state. When the clamping space 13 is opened, the magnetic part 5 moves with the moving part 12, so that the magnetic part 5 moves away from the Hall sensor 6, and the Hall sensor 6 loses induction, thereby feeding back through the device prompt that the peristaltic pump is in the open state. In this way, it is realized to automatically monitor and determine whether the peristaltic pump is closed, without manual visual observation, improving safety.

[0038] It can be understood that the working process of the peristaltic pump is mainly based on the peristaltic motion, also known as "peristaltic extrusion" or "peristaltic pump action". Its core components include a delivery pipe 4 made of an elastic material, usually referred to as the pump head 1. There is one or more extrusion rollers outside the pump head 1, which can move along the length direction of the pipe. When the extrusion rollers move, they apply pressure to the pipe on the pump head 1, thereby pushing the liquid to flow forward in the pipe. And the delivery pipe 4 is clamped through the clamping space 13 formed between the main body 11 and the moving part 12 of the pump head 1. The motor 2 drives the moving part 12 to approach or move away from the main body 11 to open or close the clamping space 13.

[0039] Please refer to Figure 4 and Figure 5 , according to a peristaltic pump for a thermal steam ablation device with built-in status monitoring provided by the present utility model, a groove 121 is formed on one side of the moving part 12 facing the Hall sensor 6, and the magnetic part 5 is installed in the groove 121.

[0040] It can be understood that the magnetic part 5 is received in the groove 121 to prevent the magnetic part 5 from protruding from the moving part 12, which can make the sliding surface of the moving part 12 tend to be flat and facilitate the sliding of the moving part 12 relative to the fixing seat 3. The sliding mode of the moving part 12 on the fixing seat 3 can be a matching structure of a slide rail and a slide groove, so that the moving part 12 slides in a certain direction.

[0041] According to a peristaltic pump for a thermal steam ablation device with built-in status monitoring provided by the present utility model, the magnetic member 5 is bonded in the groove 121 to prevent the magnetic member 5 from loosening and falling off. Fixed by bonding, the bonding material can be coated on the surface of the magnetic member 5 in advance, and then the magnetic member 5 is placed in the groove 121. Without other installation tools, the installation is convenient.

[0042] According to a peristaltic pump for a thermal steam ablation device with built-in status monitoring provided by the present utility model, an installation hole 311 is provided on one side of the fixed seat 3 facing the movable member 12. When the clamping space 13 is closed, the installation hole 311 is coaxial with the groove 121, and the Hall sensor 6 is inserted through the installation hole 311.

[0043] It can be understood that the installation hole 311 is opened on the sliding surface of the fixed seat 3 for the movable member 12 to slide. When the clamping space 13 is closed, the installation hole 311 is facing the groove 121. That is to say, when the Hall sensor 6 is installed in the installation hole 311 and the magnetic member 5 is installed in the groove 121, the Hall sensor 6 is facing the magnetic member 5, so that the Hall sensor 6 can detect the magnetic field of the magnetic member 5 and output a closed signal. When the clamping space 13 is opened, the groove 121 is away from the installation hole 311, so that the Hall sensor 6 cannot detect the magnetic member 5, and thus an open signal is output.

[0044] As Figure 5 shown, according to a peristaltic pump for a thermal steam ablation device with built-in status monitoring provided by the present utility model, there is a gap between the Hall sensor 6 and the magnetic member 5, and the gap is less than or equal to 0.5 mm. It can be understood that the size of the gap between the Hall sensor 6 and the magnetic member 5 easily affects the induction accuracy of the sensor. The gap is less than or equal to 0.5 mm, such as 0.3 mm or 0.4 mm, etc. Its induction accuracy is generally higher, but its installation difficulty generally also increases. According to the different induction accuracies of different Hall sensors 6, the installation gaps required during installation are also different. The installation distance and angle between the Hall sensor 6 and the magnetic member 5 also affect the detection effect. Appropriate installation distance and angle can maximize the magnetic field effect of the magnetic member 5 and enable the Hall sensor 6 to obtain the best signal output. The gap between the Hall sensor 6 and the magnetic member 5 is not limited herein, as long as the gap is less than or equal to 0.5 mm.

[0045] Please refer to Figure 4 and Figure 5 , according to a peristaltic pump for a thermal steam ablation device with built-in status monitoring provided by the present utility model, the fixed seat 3 is provided with a fixing plate 31, the pump head 1 is arranged above the fixing plate 31, and the installation hole 311 is opened on the fixing plate 31.

[0046] It can be understood that the pump head 1 and the Hall sensor 6 can be arranged separately above and below the fixed plate 31 to reasonably utilize the installation space and prevent the Hall sensor 6 from interfering with the operation of the pump head 1. Exemplarily, the motor 2 is also installed below the fixed plate 31, and only the rotating shaft of the motor 2 passes through the fixed plate 31 and is connected to the pump head 1 above the fixed plate 31. Specifically, the Hall sensor 6 can pass through the mounting hole 311 below the fixed plate 31 to detect the magnetic part 5 above from bottom to top. That is to say, the moving part 12 slides on the upper surface of the fixed plate 31, and a groove 121 is formed on the lower surface of the moving part 12 for installing the magnetic part 5, so that the magnetic part 5 can be directly opposite to the Hall sensor 6 below.

[0047] A peristaltic pump for a thermal steam ablation device with built-in status monitoring according to the present invention further includes a mounting seat 7. The mounting seat 7 is installed below the fixed plate 31. The mounting seat 7 is arranged corresponding to the mounting hole 311, and the Hall sensor 6 is fixedly connected to the mounting seat 7.

[0048] To improve the installation stability and convenience of the Hall sensor 6, the Hall sensor 6 is fixed by the mounting seat 7, so that the Hall sensor 6 is stably passed through the mounting hole 311. Exemplarily, the mounting seat 7 can be fixedly connected to the lower surface of the fixed plate 31 to support the Hall sensor 6 passing through the mounting hole 311. The connection method between the mounting seat 7 and the fixed plate 31 can be detachable connections such as plugging, clamping or threaded connection, so as to facilitate subsequent disassembly, repair or replacement of the Hall sensor 6.

[0049] Please refer to Figure 1 、 Figure 4 and Figure 5 , a peristaltic pump for a thermal steam ablation device with built-in status monitoring according to the present invention, the mounting seat 7 is provided with a through hole 71, the through hole 71 is communicated with the mounting hole 311, and the Hall sensor 6 is wired through the through hole 71.

[0050] It can be understood that a through hole 71 is formed at the bottom of the mounting seat 7. While the mounting seat 7 supports the Hall sensor 6, the Hall sensor 6 can be wired through the bottom of the mounting seat 7 to connect to an external device to transmit signals. In this way, it is possible to prevent the wiring from interfering with the operation of the pump head 1 above. The size of the through hole 71 is adapted to the size of the wire body, so that the wiring of the Hall sensor 6 can pass through the through hole 71, while the sensor body 11 cannot pass through the through hole 71. Of course, in other embodiments, the through hole 71 can also be formed on the side wall of the mounting seat 7, which is not limited herein.

[0051] A peristaltic pump for a thermal steam ablation device with built-in status monitoring according to the present utility model, the mounting seat 7 is threadedly connected to the fixing plate 31. Exemplarily, a first threaded hole is provided on the bottom surface of the fixing plate 31, and a second threaded hole is provided on the mounting seat 7. Screws are sequentially passed through the second threaded hole and the first threaded hole to connect the mounting seat 7 and the fixing plate 31. In other embodiments, a connecting boss may also be provided on the bottom surface of the fixing plate 31. The connecting boss is provided with an external thread, and the mounting seat 7 is provided with an internal thread. The mounting seat 7 is sleeved on the connecting boss and is threadedly connected through the internal thread and the external thread, without the assistance of other connecting members such as screws, and the installation is convenient.

[0052] The present utility model also provides a thermal steam ablation device, including the above-mentioned peristaltic pump for a thermal steam ablation device with built-in status monitoring. It can be understood that the thermal steam ablation device includes a device main body and the peristaltic pump, and the peristaltic pump is installed in the device main body.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
