Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic treatment and imaging auxiliary equipment. Specifically, it relates to a wearable water sealing device and its sealing method. Background Art

[0002] The application of focused ultrasound in clinical practice is becoming increasingly widespread, and various types of equipment have emerged one after another. The coupling between the ultrasonic emission surface of the treatment head and the human skin is an essential link that all equipment must ensure. Currently, common coupling methods include: wet coupling using a bathtub immersion method and dry coupling using a sealed water bag pressing method. The wet coupling method consumes a large amount of coupling water, is complex in operation, has a slow water circulation speed, and is prone to leakage; the dry coupling method avoids the above-mentioned shortcomings, but there are easily flaws, reflections, and absorptions at the coupling interface, which affect the efficiency of energy delivery and are prone to burns. In the prior art, when using semi-dry coupling for water sealing, generally, a cylindrical coupling cylinder is directly attached to the treatment site, which solves the problems of the above two methods and ensures the coupling quality; however, at parts where the anatomical shape of the body surface changes sharply, such as the perineum, chin, etc., or at places with thick hair such as the scalp, it is difficult to paste the semi-dry water bag completely or it is easy to fall off, resulting in water leakage. For large transducers or large lesion target areas, the amount of water storage required for semi-dry coupling increases significantly, the fitting range expands, and it is also easy to tear off and leak water. Summary of the Invention

[0003] The purpose of the present invention is to provide a wearable water sealing device to solve the problems raised in the above background art. When directly attaching a cylindrical coupling cylinder to the treatment site, firstly, the fixation is not firm and water leakage is likely to occur; secondly, this part will shake, easily pulling and breaking the skin of the fixation part, resulting in damage.

[0004] To achieve the above purpose, the present invention provides a wearable water sealing device, including a sealing main body. One end of the sealing main body is provided with a head side port. A coupling cylinder is connected to the sealing main body. The sealing main body includes two layers of structures, namely an outer layer and an inner layer. An inflation cavity is provided between the outer layer and the inner layer.

[0005] This setting sets the water sealing device in the form of a film sleeve, which is directly worn on the human torso. By positioning at three locations on the human chest and thighs, the wearing is relatively firm. Due to the double-layer structure of the sealing main body, it is convenient for inflating and forming. After inflation, the inner layer, under the action of air pressure, closely adheres to the skin, and the outer layer bulges outwards to support a stable shape. It should be emphasized here that when inflating, the coupling cylinder also inflates and expands to form a water injection cavity. The coupling cylinder can be inflated together with the sealing main body in communication or can be inflated independently without connection, which depends on the water injection volume. In this way, the inflation pressure and the cooperation of the head-side port and the foot-side sleeve port can be used to prevent leakage after water injection and play a sealing role. On this basis, the coupling cylinder can be set at any position from the head-side port to the foot-side sleeve port to perform ultrasonic treatment at any position, which can facilitate ultrasonic treatment of some difficult-to-fix parts and there are no problems of difficult fixation and positioning. Of course, it is worth emphasizing that the sealing main body in this setting refers to the structure that can be sleeved on any part of the torso, such as the neck, jaw, hand, foot, chest, abdomen, etc. Such structures are all within the scope of the sealing main body of this setting.

[0006] Preferably, two foot-side sleeves are connected to the other end of the sealing main body, and a foot-side sleeve port is provided at the outer end of the foot-side sleeve.

[0007] Preferably, a sealing ring is installed inside the head-side port, and a sealing ring is installed inside the foot-side sleeve port.

[0008] The sealing ring is set in this setting because after water injection, a very small part of the water will leak to the positions of the three sleeve ports, and the sealing ring can ensure no water leakage. Since after the technical solution is implemented, the water injection part of the sleeve is directly interconnected with the space of the sealing main body for sleeving on the human body. Under the inflation pressure, the inner layer can only achieve a roughly sealed effect, and there will still be a small part of the water reaching the positions of the three sleeve ports. This setting further improves its sealing performance.

[0009] Preferably, the coupling cylinder is in a cylindrical structure after inflation.

[0010] The cylindrical shape is adopted in this setting because the pressure distribution of the cylindrical shape is very uniform and it is the most stable shape. Of course, other shapes can also be adopted. The coupling cylinder is in a flexible and folded state when not inflated. After inflation, it stretches and stands like a dike, and is in a cylindrical structure (it can be oval or square) after inflation, enclosing the coupling water in this space.

[0011] Preferably, an air inlet pipe is connected to one side of the sealing main body, an air pump is connected to the outer end of the air inlet pipe, an exhaust pipe is connected to the other side of the sealing main body, and a valve is installed on the exhaust pipe.

[0012] Preferably, the top of the coupling cylinder is connected to a liquid inlet pipe for water injection, the outer end of the liquid inlet pipe is connected to a water pump, the outer side of the bottom of the coupling cylinder is provided with a liquid discharge port, and a sealing plug is installed on the outer side of the liquid discharge port.

[0013] Preferably, the outer side of the sealing body is squeezed by a compression pad, a compression belt, and an external pressure airbag, and a circle of adhesive tape is installed at the contact surface between the bottom of the coupling cylinder and the skin, and the adhesive tape is adhered to the skin.

[0014] Compared with the prior art, the structure of the present invention has the following beneficial effects:

[0015] The above scheme is mainly used in special medical scenarios such as ultrasonic therapy. In the wearable water-sealed device, the sealing body and coupling tube structure provided therein can be worn on the body and fixed firmly during ultrasonic coupling. The inflation of the inflatable cavity forms a seal with the skin, and the coupling liquid is sealed inside the coupling tube without leakage, ensuring that the coupling liquid submerges the ultrasonic emitting surface, and the coupling liquid is sealed or confined to a local area above the body to ensure the needs of ultrasonic coupling. The treatment device is directly coupled to the patient's body through water without a diaphragm in between, so that local ultrasonic therapy can be performed on the abdomen. The initial state of the mechanism of the present invention is a wearable membrane with a small size and convenient transportation and storage. After use, it is deflated and becomes a membrane again, which is convenient for recycling and disposal.

[0016] A further technical solution to the technical problem of the present invention is as follows: in the first step, the foot side sleeve is put on the human thigh, the foot side sleeve opening is tightened at a fixed position, the sealing body is put on the human chest, the head side opening is tightened at a fixed position, and the bottom of the coupling tube is aligned with the position requiring ultrasonic treatment; in the second step, the sealing body and the coupling tube are inflated so that the inner layer expands and squeezes toward the surface of the human body, the inner layer and the surface of the human body form a large-area fitting sealing state, and the sleeve opening is tightened to form a double sealing state, the outer layer bulges outward, and the coupling tube is inflated to form a columnar water-filled three-dimensional structure, forming a high-pressure fully sealed state; in the third step, coupling water is injected into this space, the ultrasonic treatment head is placed therein, and the water level is further increased to a suitable height to ensure that the movement of the treatment head does not affect the coupling state between the ultrasonic emitting surface and the skin, and the treatment begins. The water storage space can be in an open state, or the ultrasonic treatment head and the coupling water can be completely sealed and isolated from the outside world; in the fourth step, the tightening state of the three sleeve parts is released, the sealing body is deflated, and the large-area fitting sealing state is released. The water in the coupling cylinder can pass through the space between the inner layer and the skin and drain through the sleeve. Finally, the coupling cylinder is deflated, the high-pressure water sealing state is released, and finally the entire wearable membrane is removed from the human body.

[0017] Preferably, the foot side sleeve and the sealing body are inflated and deflated simultaneously.

[0018] Compared with the prior art, the beneficial effects of the method of the present invention are as follows: It changes the traditional water injection sealing structure and no longer relies on unstable methods such as straps and adhesive tapes. This sealing method adopts multi-level contact sealing, with better sealing effect and zero damage to human skin, completely solving the problem that coupling may cause secondary damage to the human body, and providing a better support structure, eliminating the influence of the offset formed at the water injection site during ultrasonic treatment on the fixed site, thus protecting the patient.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0026] Refer to Figures 1-4 It can be seen that the present invention provides a wearable water sealing device, whose original state is a wearable film. Due to the particularity of the original state, its characteristics cannot be shown in a plan view, so no additional drawings are provided for illustration. As Figures 1-3As shown in the figure, it includes a sealing body 1. One end of the sealing body 1 is provided with a head-side port 2, which is connected to the patient's sealing body. The other end of the sealing body 1 is connected with two foot-side sleeves 3. The outer end of the foot-side sleeve 3 is provided with a foot-side sleeve port 31, which is connected to the patient's foot. A coupling cylinder 4 is connected to the sealing body 1 to place an ultrasonic treatment device. Under the coupling of water, it explores and treats the target organ. The water in this application is coupling water. The water here must submerge the ultrasonic emission surface to ensure the need for ultrasonic coupling. Therefore, the liquid level here may be the highest part of the entire closed device. For different organs (such as the uterus, pancreas, liver), the setting position of the coupling cylinder 4 is different. The sealing body 1 includes two layers of structures, namely an outer layer 11 and an inner layer 12. An inflation cavity 13 is provided between the outer layer 11 and the inner layer 12. Through large-area inflatable compression, the sealed space in the non-treatment area is eliminated. An inner cavity 14 is provided inside the inner layer 12 for the body to enter.

[0027] Specifically, a sealing ring is installed inside the head-side port 2, and its size is adapted to the circumference of the human chest. A sealing ring is installed inside the foot-side sleeve port 31. Different methods such as pressurized tightening and bundling, and inflatable compression are used at the head-side port 2 to prevent water from leaking out through the gap between the skin and the head-side port 2, and its size is adapted to the circumference of the human thigh. Different methods such as pressurized tightening and bundling, and inflatable compression are used at the foot-side sleeve port 31 to prevent water from leaking out through the gap between the skin and the foot-side sleeve port 31.

[0028] Furthermore, after being inflated, the coupling cylinder 4 has a cylindrical structure, which is convenient for placing the treatment device.

[0029] Furthermore, an air inlet pipe 5 is connected to one side of the sealing body 1, and an air pump 51 is connected to the outer end of the air inlet pipe 5 for convenient inflation. An exhaust pipe 6 is connected to the other side of the sealing body 1, and a valve is installed on the exhaust pipe 6 for convenient exhaust.

[0030] Furthermore, the top of the coupling cylinder 4 is externally connected to a liquid inlet pipe for water injection. This is the structure of this embodiment. In this solution, the coupling cylinder 4 can choose any position to be externally connected to the liquid inlet pipe. The outer end of the liquid inlet pipe is connected to a water pump to facilitate injecting water into the coupling cylinder 4. A liquid discharge port 41 is provided on the outer side of the bottom of the coupling cylinder 4, and a sealing plug is installed outside the liquid discharge port 41.

[0031] Furthermore, the outer side of the sealing body 1 is squeezed by a compression pad, a compression belt, and an external pressure airbag to squeeze the sealed space in the non-treatment area and reduce the water storage capacity in this area. A circle of adhesive tape is installed at the contact surface between the bottom of the coupling cylinder 4 and the skin. The adhesive tape is adhered to the skin to isolate the space in the coupling cylinder 4 area from other areas. The injected water is only limited to this area, and the water consumption can be significantly reduced.

[0032] In this embodiment, it should be noted that the sealing body 1 is connected to the foot side sleeve 3 and the coupling tube 4. Of course, an inflation unit can also be set up separately, and the air can be inflated and deflated at the same time. However, due to the higher position of the coupling tube 4 during deflation, the deflation will be delayed, and the effect of preferential deformation of the sealing body 1 and the foot side sleeve 3 can still be achieved.

[0033] During use, the first step is to put the foot side sleeve on the human thigh, tighten the foot side sleeve opening at a fixed position, put the sealing body on the human chest, tighten the head side opening at a fixed position, and align the bottom of the coupling tube with the position requiring ultrasonic treatment; the second step is to inflate the sealing body and the coupling tube so that the inner layer expands and squeezes toward the surface of the human body, and the inner layer forms a large-area fitting sealing state with the surface of the human body, and the sleeve opening is tightened to form a double sealing state, the outer layer bulges outward, and the coupling tube is inflated to form a columnar water-filled three-dimensional structure, forming a high-pressure fully sealed state; the third step is to release the tightening state of the three sleeve openings, deflate the sealing body, and release the large-area fitting sealing state. The water in the coupling tube can pass through the space between the inner layer and the skin and be drained through the sleeve opening. Finally, the coupling tube is deflated to release the high-pressure sealing state, and finally the entire wearable membrane is removed from the human body.

[0034] It should be emphasized that the foot side sleeve and the sealing body should be inflated and deflated at the same time, which is the most stable. However, if the coupling tube is located far away from the foot side sleeve, the foot side sleeve can be left uninflated. However, to achieve the best effect, the foot side sleeve and the sealing body still need to be inflated and deflated at the same time.

[0035] Of course, in this solution, if the coupling tube 4 can be stable, other parts only need to be pressed with a cushion, or bonded with tape, or the sleeve mouth part is sealed with a strap, and it can also be used normally without inflation.

[0036] When the wearable water-sealed device of the present invention is used, taking focused ultrasound treatment of uterine lesions as an example, the patient is in a supine position, the ultrasound treatment device needs to be placed above the patient's lower abdomen, and the water level needs to immerse the ultrasound treatment device. The liquid level at this location is at the highest level. The following steps are implemented:

[0037] 1. Remove the clothes from the chest and abdomen of the human body, insert both feet into the device from the head side opening 2, extend them from the two openings of the foot side opening 31, lift the device up, connect the head side opening 2 to the chest, and connect the foot side opening 31 to the thigh.

[0038] 2. Align the bottom of the coupling tube 4 with the patient's lower abdomen (the anterior abdominal wall corresponding to the uterus).

[0039] 3. Tighten the head side opening 2 and the foot side opening 31 by applying pressure, tightening, bundling, inflating, and other methods to make them fit the skin completely and seal it, preventing liquid from leaking from the gap between the skin and the device.

[0040] 4. Activate the air pump 51 and inject gas, causing the entire device to expand, and the inflation chamber 13 to expand, so that the inner layer 12 exerts pressure on the skin to achieve a water seal; other non-treatment areas are limited to water by a water limiting device, which uses one of the following methods: inflation, compression pad, compression belt, external pressure airbag, adhesive tape, or a combination of several methods to form a relatively closed area between the patient's lower abdominal wall and the interior of the coupling tube 4.

[0041] 5. Place the top of the ultrasonic treatment device self-coupling tube 4 into the area, with the ultrasonic emitting surface facing the lower abdominal wall.

[0042] 6. Start the water pump and inject the water in the water tank through the degassing device and the water inlet pipe into the enclosed area of the coupling tube 4 to completely immerse the ultrasonic treatment device. Since the ultrasonic treatment device in this embodiment is higher than the patient's body surface, the coupling tube 4 can be open; if the ultrasonic treatment device in the embodiment is flush with or lower than the patient's body surface, the opening of the coupling tube 4 needs to be completely sealed from the ultrasonic treatment device to prevent water leakage.

[0043] 7. A complete and good ultrasonic channel is formed between the ultrasonic treatment device, water and skin, which is beneficial for the imaging probe of the ultrasonic treatment device to find uterine lesions and emit high-energy ultrasonic waves for treatment.

[0044] 8. During the treatment process, the water temperature will often gradually rise, which may increase the risk of skin burns. At this time, the thermostat can be started, and the water pump will inject the water in the water tank into the thermostat. After the thermostat cools it, it is injected into the coupling cylinder 4 through the water inlet pipe. The water in the coupling cylinder 4 is pumped back to the water tank by the water pump. This cycle is repeated to achieve cooling. Since the coupling cylinder 4 is isolated from other sealed spaces, the cooling speed will be significantly accelerated.

[0045] 9. Even if a small amount of water leaks out of the coupling tube 4 and enters the non-treatment area, the amount will not be large due to the presence of water-limiting devices such as the inflation device, the compression pad, the compression belt, the external pressure airbag, and the adhesive tape. Moreover, since the leakage hole is generally not large, its effect on the water temperature circulation speed will not be obvious, and the water seepage pressure on the foot-side sleeve 31 and the head-side port 2 will not be very high, thereby better solving the water sealing problem.

[0046] This embodiment uses a specific structure that is worn on the chest for explanation. For example, structures that are worn on other parts of the body, such as the hands, feet, chin, neck, etc., are very similar and are not described one by one with examples.

[0047] Finally, it should be noted that the electronic components in components such as the water pump 51 and the air pump in this embodiment are all common standard components or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods. At the idle places of this device, all the above-mentioned electrical components are respectively connected by wires. The specific connection means should refer to the sequence of operation between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the art.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
