Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to steam therapy devices and systems. Background Technology

[0002] Prostate steam therapy is a minimally invasive treatment with rapid recovery and significant efficacy. It utilizes the unique physical properties of high-temperature steam, precisely controlling its temperature, pressure, and duration to directly apply heat energy to the enlarged prostate tissue. The high-temperature steam rapidly denatures and coagulates the proteins within the enlarged tissue, leading to cell necrosis and subsequent shrinkage of the tissue. This relieves urethral obstruction and improves urinary symptoms.

[0003] In existing technologies, the equipment used in prostate steam therapy surgery mainly consists of two parts: a main unit and a treatment terminal device. The main unit, as the core control unit of the entire system, is responsible for precisely controlling the generation and delivery parameters of the steam, as well as various key indicators during the treatment process, ensuring the safety and effectiveness of the treatment. The treatment terminal device acts directly on the patient's lesion site and includes key components such as a sheath and a puncture needle. The sheath is used to precisely deliver the steam to a specific area of ​​the prostate, and the puncture needle assists the sheath in accurately reaching the target location. Simultaneously, the treatment terminal device also integrates electrical components such as a drive system. These components work together to ensure that the treatment terminal device can operate stably according to a preset program, achieving precise treatment operations.

[0004] Because some structures of the entire treatment terminal device are inserted into the patient's body during treatment, the device is designed as a disposable consumable. A completely new treatment terminal device needs to be replaced after each surgery to avoid the risk of cross-infection. This results in a significant increase in the cost of consumables in the entire treatment plan, and the proportion of consumable costs in the treatment cost is also significantly high. Summary of the Invention

[0005] The purpose of this invention is to provide a steam therapy device and system that solves the problem that existing steam therapy solutions involve a large number of disposable consumables, resulting in high consumable costs and a significant proportion of the overall treatment cost, thus placing a heavy economic burden on patients.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a steam therapy apparatus comprising:

[0008] Top shell;

[0009] A sheath is inserted through the upper shell;

[0010] A puncture needle is inserted into the sheath and can slide relative to the sheath. One end of the puncture needle is used for puncture, and the other end is detachably connected to a steam supply assembly, which is used to supply therapeutic steam into the puncture needle.

[0011] The lower shell is detachably connected to the upper shell via a connecting assembly;

[0012] A puncture drive assembly is disposed within the lower housing and can be connected to the puncture needle to drive the puncture needle to perform puncture.

[0013] Optionally, the connecting assembly includes a hook, one of the upper shell and the lower shell is provided with the hook, and the other is provided with a locking hole for insertion and engagement with the hook; and / or,

[0014] The connecting assembly includes a locking element, which is provided on one of the upper and lower shells, and the locking element can be elastically locked to the other.

[0015] Optionally, the locking element includes a locking plate, which is slidably connected to one of the upper shell or the lower shell. An elastic element is provided on one side of the locking plate to restrict its sliding. The other of the upper shell or the lower shell is provided with a locking block, which can be inserted and engaged with the locking plate and locked by the action of the elastic element.

[0016] Optionally, the steam therapy device further includes:

[0017] A sliding seat is fixedly connected to the puncture needle and partially extends through the upper shell and into the lower shell, with the sliding seat slidingly engaged with the lower shell;

[0018] The puncture drive component includes:

[0019] The drive unit is slidably connected to the lower housing and is inserted into the sliding seat;

[0020] A driving element, connected to the driving unit, drives the puncture needle to move via the driving unit and the sliding seat.

[0021] Optionally, the lower housing has a mounting cavity, and the steam supply assembly is inserted into the mounting cavity and detachably connected to the lower housing.

[0022] Optionally, one of the lower shell and the steam supply assembly is provided with a slot, and the other is provided with a locking block that can engage with the slot.

[0023] Optionally, the steam supply assembly includes:

[0024] chassis;

[0025] A distillation tube, one end of which is used to inject sterile water;

[0026] A heating element is provided in the distillation tube to convert the sterile water in the distillation tube into steam;

[0027] A first one-way connector is located at the other end of the distillation tube and is sealed and connected to the puncture needle to deliver steam to the puncture needle in one direction.

[0028] Optionally, a pressure switch is provided at one end of the distillation tube near the first one-way connector.

[0029] Optionally, the first unidirectional connector includes:

[0030] A connecting pipe is provided with a steam supply channel for conveying steam. The steam supply channel has a closed cavity. The closed cavity is provided with a sealing element and a limiting element. The limiting element has an elastic tendency to push the sealing element to close the steam supply channel so that when the steam flows to the puncture needle, it can push open the sealing element and open the steam supply channel.

[0031] Optionally, the steam therapy device further includes:

[0032] An adapter is provided on the upper housing. The endoscope tube of the sheath is inserted into the adapter and sealed to the adapter. The adapter has a water inlet connector and a water outlet connector. The water inlet connector is connected to a water inlet pipe for injecting liquid for cleaning the endoscope. The water outlet connector is used to drain the liquid for cleaning the endoscope.

[0033] Optionally, the water inlet pipe is disposed in the steam supply assembly.

[0034] Optionally, the steam therapy device further includes:

[0035] A diverter block is disposed inside the upper shell. The diverter block has a first connector and a second connector. One end of the first connector is connected to the steam supply assembly, and the other end is connected to the puncture needle through a pipeline. One end of the second connector is connected to the water inlet connector, and the other end is connected to the second one-way connector of the water inlet pipe.

[0036] In a second aspect, the present invention also provides a steam therapy system comprising:

[0037] Host;

[0038] The steam therapy device as described in any one of the first aspects is communicatively connected to the main unit.

[0039] The beneficial effects of this invention are:

[0040] Firstly, by using a connecting component to create a detachable connection between the upper and lower shells, the puncture needle is connected to the puncture drive component. During treatment, the sheath is first inserted into the patient's body, and the puncture drive component propels the puncture needle to the affected area. Steam is then introduced into the puncture needle via the steam supply component, allowing the needle to deliver the steam to the affected area for treatment. After treatment, the upper and lower shells are simply detached, the connection is released, and the upper shell, sheath, and puncture needle are discarded as disposable consumables. The lower shell is cleaned, disinfected, and sterilized before storage, and can be reused by wiping with alcohol or soaking for further disinfection. Therefore, when this steam therapy device is used to treat patients, the upper and lower shells are first connected together using a connecting component to form a treatment terminal device. After the treatment is completed, the upper and lower shells can be separated, and only the upper shell and related structures are discarded as consumables. The lower shell can be reused. This not only effectively reduces the number of consumables that need to be discarded in a single treatment, but also ensures that the discarded consumables are only low-cost materials such as the upper shell, sheath, and puncture needle, while the higher-cost electrical components and the lower shell can be reused. This significantly reduces the proportion and cost of consumables in a single treatment, thereby effectively reducing the cost of consumables in the treatment cost and helping to alleviate the economic burden on patients.

[0041] Secondly, when using this steam therapy system, the main unit controls the corresponding electrical components within the steam therapy device to precisely implement the corresponding treatment plan. After the treatment is completed, only a portion of the steam therapy device needs to be discarded, while the more expensive components, such as electrical components, can be recycled and reused after processing. This effectively reduces the number of consumables that need to be discarded in a single treatment, thereby reducing the cost of consumables and lowering the overall treatment cost, thus alleviating the economic burden on patients.

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0069] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0070] like Figures 1 to 14 As shown, the present invention provides a steam therapy device and system.

[0071] Reference Figures 1 to 3 The steam therapy device includes an upper shell 1, a sheath 2, a puncture needle 3, a lower shell 4, and a puncture drive assembly 5. The sheath 2 is inserted into the upper shell 1; the puncture needle 3 is inserted into the sheath 2 and can slide relative to the sheath 2. One end of the puncture needle 3 is used for puncture, and the other end is detachably connected to the steam supply assembly 6, which is used to supply therapeutic steam into the puncture needle 3; the lower shell 4 and the upper shell 1 are detachably connected by a connecting assembly 7; the puncture drive assembly 5 is disposed in the lower shell 4 and can be connected to the puncture needle 3 to drive the puncture needle 3 to perform puncture.

[0072] The upper shell 1 and lower shell 4 are detachably connected by the connecting component 7, allowing the puncture needle 3 to connect with the puncture drive component 5. During treatment, the sheath 2 is first inserted into the patient's body, and the puncture drive component 5 drives the puncture needle 3 to puncture the affected area. Steam is then introduced into the puncture needle 3 by the steam supply component 6, allowing the needle to deliver steam to the affected area for treatment. After treatment, the upper shell 1 and lower shell 4 are simply detached, and the connection formed by the connecting component 7 is released. The upper shell 1, sheath 2, and puncture needle 3 are discarded as disposable consumables. The lower shell 4 is cleaned, disinfected, and sterilized before storage. For future use, it can be disinfected again by wiping with alcohol or soaking for reuse. Therefore, when this steam therapy device is used to treat patients, the upper shell 1 and the lower shell 4 are first connected together using the connecting component 7 to form a treatment terminal device. After the treatment is completed, the upper shell 1 and the lower shell 4 can be separated. Only the upper shell 1 and related structures can be discarded as consumables, while the lower shell 4 can be reused. This not only effectively reduces the number of consumables that need to be discarded in a single treatment, but also ensures that the discarded consumables are only low-cost materials such as the upper shell 1, sheath 2, and puncture needle 3, while the higher-cost electrical components and the lower shell 4 can be reused. This can significantly reduce the proportion and cost of consumables in a single treatment, thereby effectively reducing the cost of consumables in the treatment cost and helping to alleviate the economic burden on patients.

[0073] Reference Figures 3 to 5Specifically, the upper shell 1 is elongated and is formed by two shell structures joined together from left to right. A sheath 2 is inserted through the front of the upper shell 1. The sheath 2 includes a scope tube 21 and a needle tube 22, which are fixedly connected and have an "8"-shaped cross-section. The fixing method can be adhesive, welding, or fusion. An endoscope is inserted into the scope tube 21, and a puncture needle 3 is inserted into the needle tube 22. Heat-shrink tubing 23 covers the outside of the scope tube 21 and the needle tube 22. A tube seat 24 is provided at one end of the sheath 2, and the tube seat 24 is fixedly connected to the front of the upper shell 1. The fixing method can be adhesive, snap-fit, welding, or fusion. The other end of the sheath 2 has an opening for the puncture needle 3 and endoscope to extend out. A needle pad is placed at the opening where the puncture needle 3 extends out, and the needle pad is sealed and waterproof. One end of the puncture needle 3 passes through the needle pad, and the other end extends out of the sheath 2 and is located inside the upper shell 1. It can connect with the puncture drive assembly 5 inside the lower shell 4 when the upper shell 1 and the lower shell 4 are installed, and it can separate from the puncture drive assembly 5 when the upper shell 1 and the lower shell 4 are separated. Multiple buttons 41 and circuit boards 42 electrically connected to the buttons 41 can be provided on the lower shell 4. The multiple buttons 41 can control the operation of the steam supply assembly 6 and the puncture drive assembly 5 respectively. The upper shell 1 and the lower shell 4 are detachably connected by a connecting assembly 7. The connecting assembly 7 can be a hook structure, a plug structure, a magnetic structure, a snap-fit ​​structure, or a screw, etc.

[0074] Reference Figure 6 and Figure 7 Optionally, the connecting component 7 includes a hook 71. One of the upper shell 1 and the lower shell 4 is provided with the hook 71, and the other is provided with a locking hole 72 that engages with the hook 71.

[0075] Specifically, taking the example of setting a hook 71 on the bottom wall of the upper shell 1, the hook 71 is set near the front side of the upper shell 1. The lower shell 4 is formed by splicing two shells that are symmetrically arranged on the left and right sides. A corresponding locking hole 72 is opened on the front side of the lower shell 4. During installation, the hook 71 is inserted into the locking hole 72 to install the upper shell 1 and the lower shell 4 together. The hook 71 and locking hole 72 can also be set on the rear side of the upper shell 1 and the lower shell 4 to form a stable connection on both the front and rear sides of the upper shell 1 and the lower shell 4. In other embodiments, the hook 71 and locking hole 72 can be set only on the front side of the upper shell 1 and the lower shell 4, while the rear side can be provided with a concave-convex fitting limiting structure, magnetic structure, or buckle structure, which can also stably connect the upper shell 1 and the lower shell 4 together. Moreover, the hook 71 can also be set on the lower shell 4, and the locking hole 72 is opened at the corresponding position on the upper shell 1.

[0076] Optionally, the connecting component 7 includes a locking element 73, which is provided on one of the upper shell 1 and the lower shell 4, and the locking element 73 can be elastically locked with the other.

[0077] Specifically, the locking member 73 can be composed of an elastic structure. Taking the locking member 73 in the lower shell 4 as an example, the locking member 73 is set on the inner side of the lower shell 4, and a notch corresponding to the locking member 73 is opened on the top wall of the lower shell 4. A protruding structure is set on the upper shell 1. The protruding structure can be inserted into the notch and squeezed with the locking member 73 to form an elastic lock with the locking member 73, which can fix the upper shell 1 and the lower shell 4 together.

[0078] To further simplify the structure, the locking member 73 may optionally include a locking plate 731, with the locking plate 731 slidably connected to one of the upper shell 1 or the lower shell 4. An elastic member 732 is provided on one side of the locking plate 731 to restrict the sliding of the locking plate 731, and a locking block 733 is provided on the other of the upper shell 1 or the lower shell 4. The locking block 733 can be inserted and engaged with the locking plate 731 and locked by the action of the elastic member 732.

[0079] Specifically, taking the example of locking element 73 being located in the lower shell 4, locking plate 731 is slidably connected to the rear side of lower shell 4, with one side of locking plate 731 extending out of lower shell 4 and elastic element 732 located on the other side. Elastic element 732 can be a spring or an elastic rod, etc. Locking block 733 is located on the bottom wall of upper shell 1 and can be inserted into lower shell 4. During installation, locking plate 731 can be manually squeezed so that the notch on locking plate 731 corresponds to locking block 733, causing locking block 733 to engage with locking plate 731. The sliding of locking plate 731 will squeeze elastic element 732. When locking block 733 engages with locking plate 731, the elastic tendency generated by elastic element 732 will continuously push locking plate 731 against locking block 733, thus successfully achieving elastic locking. In other embodiments, locking element 73 can also be located in upper shell 1, in which case locking block 733 can be correspondingly located in lower shell 4.

[0080] It should be understood that the connecting component 7 may only have a hook 71 and a locking hole 72, or only a locking element 73, or both. The specific design can be tailored to the overall stability of the connection between the upper shell 1 and the lower shell 4, as well as the ease of assembly and disassembly. In this embodiment, a hook 71 is provided on the front side of the upper shell 1, and a locking element 73 is provided on the rear side of the lower shell 4, allowing the front sides of the upper shell 1 and lower shell 4 to engage, while the rear sides are locked by the locking element 73. In other embodiments, the locking element 73 may also be provided on the front side of the lower shell 4, and the hook 71 may also be provided on the rear side of the upper shell 1.

[0081] After the upper shell 1 and lower shell 4 are installed, the puncture needle 3 needs to be connected to the puncture drive assembly 5 so that the puncture drive assembly 5 can drive the puncture needle 3. The puncture needle 3 can be detachably connected to the puncture drive assembly 5 via a sliding structure. The sliding structure can also be fixedly connected to the puncture needle 3. When the upper shell 1 and lower shell 4 are installed, the sliding structure is inserted into the lower shell 4 and connected to the puncture drive assembly 5. When the upper shell 1 and lower shell 4 are separated, the sliding structure and the puncture drive assembly 5 will also separate. Alternatively, the sliding structure can be fixed to the puncture drive assembly 5. When the upper shell 1 and lower shell 4 are installed, the sliding structure is inserted into the upper shell 1 and connected to the puncture needle 3. When the upper shell 1 and lower shell 4 are separated, the sliding structure and the puncture needle 3 will also separate. In other embodiments, the connection between the puncture needle 3 and the puncture drive assembly 5 can also be achieved through magnetic connection or threaded connection, etc., depending on the actual driving requirements and assembly / disassembly method.

[0082] Because the puncture needle 3 is relatively small, it is difficult to form a detachable connection. Furthermore, since the puncture needle 3 is inserted into the patient's body and is a disposable consumable, the sliding structure, which is in direct contact with the puncture needle 3, should also be discarded to avoid cross-infection. Therefore, it is preferable to fix the sliding structure to the puncture needle 3. For example, a slider can be provided on the puncture needle 3, and a slot can be provided at the corresponding position on the lower shell 4 for the slider to extend into. The slider can also be replaced with a sliding rod or other sliding structure.

[0083] Reference Figure 8 and Figure 9 Optionally, the steam therapy device includes a sliding seat 25. The sliding seat 25 is fixedly connected to the puncture needle 3 and partially extends through the upper shell 1 and into the lower shell 4, with the sliding seat 25 slidably engaged with the lower shell 4; the puncture drive assembly 5 includes a drive part 51 and a drive member 52. The drive part 51 is slidably connected within the lower shell 4 and engages with the sliding seat 25; the drive member 52 is connected to the drive part 51 to drive the puncture needle 3 to move via the drive part 51 and the sliding seat 25.

[0084] Specifically, the driving component 52 is fixed inside the lower shell 4. It can be a spring-driven structure, an electromagnetic drive structure, or a motor-driven mechanism. The driving component 52 can drive the driving part 51 to move. The driving part 51 has a groove that engages with the sliding seat 25. When the driving part 51 moves, the sliding seat 25 can also move synchronously, thus enabling the puncture of the puncture needle 3. The specific puncture amplitude and puncture method can be controlled by setting the driving component 52 according to the treatment plan. For example, it can be continuous puncture or single puncture. When the treatment is completed, as the upper shell 1 separates from the lower shell 4, the sliding seat 25 can be pulled out from the driving part 51, thus separating the puncture needle 3 from the puncture driving assembly 5.

[0085] A reset rod 251 is provided on the upper side of the sliding seat 25, and a reset groove 11 is provided on the top wall of the upper shell 1. The upper end of the reset rod 251 passes through the reset groove 11 and can slide along the reset groove 11. In an emergency, the reset rod 251 can be operated to force a reset.

[0086] After the puncture needle 3 and the puncture drive assembly 5 are successfully connected, the tail end of the puncture needle 3 also needs to be connected to the steam supply assembly 6 to continuously receive the treatment steam. The steam supply assembly 6 can be set up independently, that is, it can be connected to the puncture needle 3 through a pipeline to deliver steam without being attached to the structure of the upper shell 1 and the lower shell 4. In this way, the steam supply assembly 6 can also be reused. In order to optimize the structural layout, the steam supply assembly 6 is detachably installed on the lower shell 4. In order to facilitate the operation of the lower shell 4, the lower shell 4 has a mounting cavity, and the steam supply assembly 6 is inserted into the mounting cavity and detachably connected to the lower shell 4.

[0087] Reference Figure 7 , Figures 9 to 11 To simplify the assembly and disassembly of the steam supply component 6, the detachable connection between the steam supply component 6 and the lower shell 4 can be achieved by snap-fit ​​engagement. Optionally, one of the lower shell 4 and the steam supply component 6 is provided with a slot 611, and the other is provided with a snap-fit ​​block 43 that can engage with the slot 611.

[0088] Taking the example of setting a locking block 43 on the lower shell 4, the locking block 43 can be rotatably connected to the lower shell 4. When the steam supply component 6 is inserted into the mounting cavity, the locking groove 611 corresponds exactly to the locking block 43, so the steam supply component 6 can be locked into the mounting cavity by rotating the locking block 43 into the locking groove 611. It should be understood that the locking block 43 can also be slidably connected to the lower shell 4, or inserted into the lower shell 4, or the locking block 43 can be set on the steam supply component 6, and the locking groove 611 is opened in the mounting cavity. In other embodiments, bolts, pins, or other structures can be used to replace the locking block 43. The specific detachable connection structure between the steam supply component 6 and the lower shell 4 can be designed according to the actual operational convenience, and the present invention does not limit it.

[0089] After the steam supply component 6 is connected to the puncture needle 3, sterile water can be converted into steam by heating and delivered to the puncture needle 3. The heating method can be radio frequency coil heating or heating of a specific heating element 63.

[0090] Optionally, the steam supply assembly 6 includes a housing 61, a distillation tube 62, a heating element 63, and a first one-way connector 64. One end of the distillation tube 62 is used to inject sterile water; the heating element 63 is disposed on the distillation tube 62 to convert the sterile water in the distillation tube 62 into steam; the first one-way connector 64 is disposed on the other end of the distillation tube 62 and is sealed and connected to the puncture needle 3 to deliver steam to the puncture needle 3 in one direction.

[0091] Specifically, the housing 61 is elongated and can be inserted into the mounting cavity. A first electrical connector 44 is provided inside the lower housing 4, and a second electrical connector 66 is provided on the housing 61. The first electrical connector 44 can be electrically connected to the second electrical connector 66, thereby allowing the operation of the steam supply component 6 to be controlled via button 41. The distillation tube 62 passes through the housing 61, and a first one-way connector 64 is provided at the upper end of the distillation tube 62. The first one-way connector 64 is connected to the puncture needle 3 to unidirectionally supply steam to the puncture needle 3. The heater can be a radio frequency heating structure or a resistance wire heating structure, etc., and the present invention is not limited to this. To further improve the detection of the gas pressure inside the distillation tube 62, a pressure switch 65 is provided at the end of the distillation tube 62 near the first one-way connector 64. The pressure switch 65 can detect the gas pressure in real time, and only when the gas pressure meets the treatment plan will steam be released to the first one-way connector 64, thereby ensuring that the treatment effect can achieve the expected results.

[0092] Reference Figure 12 and Figure 13 The first one-way connector 64 is provided to prevent steam backflow. Optionally, the first one-way connector 64 includes a connecting pipe 641. The connecting pipe 641 is provided with a steam supply channel 642 for conveying steam. The steam supply channel 642 has a closed cavity 643. The closed cavity 643 is provided with a sealing element 644 and a limiting element 645. The limiting element 645 has an elastic tendency to push the sealing element 644 to close the steam supply channel 642, so that when steam flows to the puncture needle 3, it can push open the sealing element 644 and open the steam supply channel 642.

[0093] Specifically, a vertical channel is opened through the connecting pipe 641 as a steam supply channel 642. A closed cavity 643 is opened in the middle of the steam supply channel 642. A sealing element 644 and a limiting element 645 are installed in the closed cavity 643. The sealing element 644 can be spherical, cylindrical, cubic or diaphragm-shaped. The limiting element 645 can be an elastic structure such as a spring or elastic rod or a solid structure such as a counterweight. The sealing element 644 and the limiting element 645 cooperate to block the steam supply channel 642. When steam flows from the pressure switch 65 to the puncture needle 3, the steam pressure can push the sealing element 644 and the limiting element 645 open, thereby opening the steam channel. When the steam flows back, the steam will act on the side of the sealing element 644 and push the sealing element 644 to block the steam channel, thereby preventing backflow steam from entering the distillation tube 62.

[0094] Since the steam supply component 6 needs to be plugged in and installed, and the puncture needle 3 needs to be punctured and moved, the tail end of the puncture needle 3 needs to be connected through a hose to deliver steam. To facilitate the connection between the steam supply component 6 and the puncture needle 3, the steam therapy device may optionally include a diverter block 8. The diverter block 8 has a first connector 81, one end of which is connected to the steam supply component 6, and the other end is connected to the puncture needle 3 through a pipeline.

[0095] Specifically, the diverter block 8 is fixed inside the upper shell 1, and the corresponding position of the upper shell 1 communicates with the mounting cavity of the lower shell 4. This allows the first one-way connector 64 to be inserted into the connection hole of the diverter block 8 and form a sealed connection through the sealing gasket 82 after the housing 61 of the steam supply assembly 6 is inserted into the mounting cavity. A first connector 81 supported by a stainless steel tube is provided on the upper side of the diverter block 8. The lower end of the first connector 81 communicates with the connection hole, and the upper end communicates with the puncture needle 3 through a flexible tube. This allows the steam supply assembly 6 to achieve a sealed connection with the puncture needle 3 after insertion, further simplifying the installation of the entire instrument.

[0096] Reference Figures 11 to 14 After installation, the endoscope needs to be cleaned. To address this issue, the steam therapy device may optionally include an adapter 9. The adapter 9 is located on the upper housing 1. The endoscope tube 21 of the sheath 2 is inserted into and sealed to the adapter 9. The adapter 9 has a water inlet connector 91 and a drain connector 92. The water inlet connector 91 is connected to a water inlet pipe 93 for injecting liquid to clean the endoscope, and the drain connector 92 is used to drain the liquid used to clean the endoscope.

[0097] Specifically, the adapter 9 is block-shaped with a through hole in its middle. One end of the through hole is inserted into the endoscope tube 21, and a sealing ring 26 is provided at the insertion point to form a sealed connection. The other end of the through hole serves as the insertion inlet 94 of the endoscope and is correspondingly provided with a sealing ring 95 to form a sealed connection. The adapter 9 is provided with a water inlet connector 91 and a drain connector 92 communicating with the through hole. The two connectors are respectively connected to the water inlet pipe 93 and the drain pipe. During cleaning, the cleaning liquid can be injected into the adapter 9 through the water inlet pipe 93 to clean the endoscope. At this time, the drain pipe is closed. When draining, the water inlet pipe 93 is closed, and the drain pipe is opened alone. The closing and opening of the water inlet pipe 93 and the drain pipe can be achieved by pipe clamps or by special valves. This invention is not limited to these methods.

[0098] The drain pipe can be installed separately and guided to the waste liquid pool for drainage, while the water inlet pipe 93 can be further integrated into the lower shell 4. Optionally, the water inlet pipe 93 is installed in the steam supply assembly 6. In this example, a hole can be provided in the housing 61 of the steam supply assembly 6 as the installation position of the water inlet pipe 93, so that the water inlet pipe 93 and the distillation pipe 62 are arranged in parallel, so that the steam supply assembly 6 can also play the role of cleaning the endoscope.

[0099] When the water inlet pipe 93 is installed on the steam supply assembly 6, in order to facilitate the connection between the water inlet pipe 93 and the water inlet connector 91, the diverter block 8 may optionally have a second connector 83, one end of the second connector 83 being connected to the water inlet connector 91 and the other end being connected to the second one-way connector 931 of the water inlet pipe 93.

[0100] Specifically, the second one-way connector 931 has the same structure as the first one-way connector 64, which will not be described in detail here. However, to accommodate the flow of liquid, the channel diameter inside the second one-way connector 931 is larger, so that the cleaning fluid can enter the adapter 9 in sufficient quantity to clean the endoscope. Similarly, the shape of the second connector 83 is similar to that of the first connector 81, with the only difference being the inner diameter of the channel. To improve airtightness, a sealing gasket 82 is also provided between the second one-way connector 931 and the diverter block 8 for sealing.

[0101] The integration of the first connector 81 and the second connector 83 on the diversion block 8 further concentrates the various structures, simplifying the composition of the internal structure of the upper shell 1, thereby further reducing the manufacturing difficulty and cost of disposable consumables.

[0102] The steam therapy system includes a main unit and steam therapy devices as described above. The steam therapy devices are communicatively connected to the main unit.

[0103] When in use, the steam therapy system controls the corresponding electrical components within the steam therapy device via the main unit to precisely implement the corresponding treatment plan. After the treatment is completed, only a portion of the steam therapy device needs to be discarded, while the more expensive components, such as the electrical components, can be recycled and reused after processing. This effectively reduces the number of consumables that need to be discarded in a single treatment, thereby reducing the cost of consumables and lowering the overall treatment cost, thus alleviating the economic burden on patients.

[0104] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
