Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a full-silicone ultrasonic therapeutic head of an ultrasonic therapeutic instrument. Background Art

[0002] Ultrasonic pulse conductivity therapy technology is a new dosage form and pharmaceutical method that uses physical power as a driving force to allow drugs to pass through intact skin and then enter the human circulation and diseased tissues to exert drug therapeutic effects. This medical technology that achieves targeted drug delivery and precise drug administration has many advantages over oral and injection methods. The ultrasonic conductivity meter transmits the pulse force generated to the metal electrode through the ultrasonic treatment head in its own structure, allowing the drug in the foam cotton to penetrate the skin and enter the body. The conductivity meter will generate microcurrent between the metal electrode and the human body to promote drug absorption on the human body surface.

[0003] The structure of the existing ultrasonic therapy heads on the market is mostly a hard shell structure that is clamped up and down, with a built-in ultrasonic transducer and circuit board. A stainless steel metal connecting plate is provided on the front of the ultrasonic therapy head, and the electrode patch consumables are fixed to the front of the ultrasonic therapy head by magnetic attraction, bonding or clamping, so that the metal electrode sheet on the back of the electrode patch fits tightly with the metal connecting sheet on the front of the ultrasonic therapy head, so that the ultrasonic transducer can transmit ultrasound to the electrode patch consumables through the metal connecting sheet and pass a microcurrent.

[0004] Currently, the ultrasonic treatment heads on the market all transmit ultrasound through the metal connecting plate on the front. The metal connecting plate and the ultrasonic transducer are fixedly connected by conductive glue. When using the same ultrasonic transducer, the ultrasonic power of the treatment head is roughly the same and there will be no obvious improvement.

[0005] Moreover, since the shell of the ultrasonic treatment head is a hard shell structure, its internal cavity structure requires the design of studs, tapping of screw holes, surface cleaning and other operations, which makes it more troublesome to manufacture and install. Since the shell is hard, it cannot fit perfectly with the human skin, which affects the effect of ultrasonic treatment. The hard shell is also easy to break and cannot be completely cleaned with water. Utility Model Content

[0006] The purpose of the utility model is to provide a full-silicone ultrasonic treatment head of an ultrasonic treatment device which can effectively solve the above-mentioned problems and enable the electrode patch to be better fixed on the treatment head.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a full silicone ultrasonic treatment head of an ultrasonic therapeutic instrument, including a treatment head, an ultrasonic transducer and a data interface, the front of the treatment head is provided with a ring-shaped slot for installing an electrode patch, the back of the treatment head is provided with a mounting slot for installing an ultrasonic transducer, and the side of the treatment head is provided with a wiring slot. The entire treatment head is made of silicone, only the slot of the treatment head is a conductive silicone layer, and the rest of the parts are non-conductive silicone. A conductive circular hole is provided on the inner side wall of the mounting groove, and the conductive circular hole is opened into the conductive silicone layer. The mounting groove is sealed by silicone injection molding.

[0008] Preferably, the wiring trough is flat, and the data interface is placed in the wiring trough.

[0009] Preferably, a boss is provided in the slot to facilitate close fitting of the bottom surface of the electrode patch.

[0010] Preferably, the front side of the ultrasonic transducer is in close contact with the inner bottom surface of the mounting groove, and is sealed in the treatment head by silicone injection molding.

[0012] Preferably, the upper end surface of the annular groove is an elastic closing structure, and the back of the electrode patch is provided with an annular clamping piece matching the annular groove, and the front side of the treatment head is clamped by the annular clamping piece.

[0013] Compared with the prior art, the advantages of the present invention are as follows: the present invention has made a new structural design for the existing ultrasonic treatment head, eliminated the metal electrical connection plate design on the treatment head, the entire treatment head body is integrally formed with silicone, the metal electrode plate is replaced by conductive silicone, and the transducer is directly embedded in the silicone body.

[0020] The utility model will be further described below.

[0021] Embodiment: A full silicone ultrasonic treatment head of an ultrasonic therapeutic apparatus, see Figures 1 to 4 , including a treatment head 1, an ultrasonic transducer 2 and a data interface, the front of the treatment head 1 is provided with an annular card slot 6 for installing an electrode patch, the back of the treatment head 1 is provided with an installation slot 3 for installing the ultrasonic transducer 2, the side of the treatment head 1 is provided with a wiring slot 4, the entire treatment head 1 is made of silicone, only the card slot of the treatment head 1 is a conductive silicone layer 01, the conductive silicone layer 01 is used for electrical pulse conduction, and the rest of the parts are non-conductive silicone 02, a conductive circular hole 5 is provided on the inner side wall of the installation slot 3, the conductive circular hole 5 is opened to the conductive silicone layer 01, and the conductive silicone layer 01 is charged immediately when the wire is inserted from the conductive circular hole 5, the installation slot 3 is sealed and filled with silicone injection molding, and the ultrasonic transducer 2 is embedded in the treatment head 1.

[0022] The utility model has a completely new structural design for the existing ultrasonic treatment head 1, canceling the metal electrical connection sheet design on the treatment head 1. The entire treatment head 1 body is integrally formed with silicone, and the metal electrode sheet 9 is replaced by conductive silicone, and the transducer is directly embedded in the silicone body. Compared with the existing ultrasonic treatment head 1 with a hard shell structure, the utility model not only has great advantages in structure, but also has been confirmed through experiments that its ultrasonic power is increased by 6 times compared with the traditional structure, bringing great technological innovation. At present, the sample of this product has been successfully developed and is ready to enter the clinical trial stage.

[0023] A comparative test experiment was conducted on the 7020PLUS silicone treatment head 1 developed by the utility model:

[0024] The ultrasonic transducer 2 is embedded in the silicone for integral molding. The diameter of the ultrasonic transducer 2 is 20 mm, the service life is 500 MS, the duty cycle is 80%, and the thickness of the silicone is tested to be 2 mm to 7 mm. The metal connecting sheet ultrasonic treatment head 1 of the conventional stainless steel sheet is compared with the thickness of the tested silicone. The thickness of the tested silicone is the thickness from the front of the ultrasonic transducer 2 to the upper surface of the boss 7 in the annular slot 6, that is, the distance from the ultrasonic transducer 2 to the metal electrode sheet 9 of the patch after the electrode patch is installed. The experimental results are as follows:

[0025]

[0026] Through experiments, it was found that the ultrasonic power of silicone material increased by 6 times compared with stainless steel sheet, and the ultrasonic power deviation of different thicknesses was not large. When the output power of the treatment head is the same, because the silicone treatment head has lower input power than the traditional treatment head, the heating temperature of its ultrasonic transducer is also much lower than the traditional stainless steel connecting sheet treatment head.

[0027] The wiring groove 4 is flat, the data interface is placed in the wiring groove 4, the data interface is set on the side, and the components in the treatment head 1 are electrically connected to the drive control circuit in the treatment instrument through the data interface. The card slot is provided with a boss 7 for facilitating the close fit of the bottom surface of the electrode patch. The boss 7 is designed to facilitate the close fit of the metal electrode sheet 9 on the back of the electrode patch with the treatment head 1, and to achieve good electrical conduction and ultrasonic transmission effects, so as to generate microcurrent to promote the absorption of drugs on the skin surface.

[0028] The front side of the ultrasonic transducer 2 is tightly attached to the inner bottom surface of the mounting groove 3 to facilitate ultrasonic conduction, and is sealed in the treatment head 1 by silicone injection molding. During manufacturing and installation, it is only necessary to place the ultrasonic transducer 2 into the mounting groove 3, insert the circuit board, connect the corresponding wires and perform injection molding and sealing. This is more convenient and quicker than the traditional hard cavity structure.

[0029] It also includes a temperature sensor, which is installed on the back of the ultrasonic transducer 2. The temperature of the ultrasonic transducer 2 can be detected by the temperature sensor so that the ultrasonic therapeutic device can adjust the working temperature of the transducer.

[0030] The upper end surface of the annular groove 6 is an elastic closing structure, and the back of the electrode patch is provided with an annular clamping piece matching the annular groove 6, and the front of the treatment head 1 is clamped by the annular clamping piece.

[0031] As a medical consumable, the electrode patch needs to be used in conjunction with the silicone treatment head 1 of the utility model. In order to realize the clamping connection between the electrode patch and the annular groove 6 of the silicone treatment head 1, a rotating clamping electrode patch designed by our company before can be directly used. The patent name is a rotating assembled electrode patch and its treatment head 1, 2023210346119. The main body of the electrode patch is composed of a water stop ring 8, a metal electrode sheet 9, a rotating connector 10, a spunlace cloth carrier 11 and a pressure-sensitive adhesive ring 12 from top to bottom. The main body of the electrode patch is clamped with the treatment head 1 through the rotating connector 10. It is only necessary to widen the clamping teeth of the rotating connector 10, such as Figure 5 As shown, the electrode patch can be snap-connected with the silicone treatment head 1 of the present invention.

[0032] Compared with the traditional treatment head 1, the utility model is made of silicone as a whole, so that the treatment head 1 can better fit the human body surface, and is strong and resistant to falling, easy to clean, and can be put into water for cleaning as a whole, and there will be no leakage, and it is very convenient to clean the annular card slot 6. Since the silicone material has good elasticity, when installing the electrode patch, you only need to align it with the annular card slot 6 and press it in. After the treatment, the electrode patch can be directly torn off, which is very convenient.

[0033] The above is a detailed introduction to the all-silicone ultrasonic treatment head of an ultrasonic therapeutic device provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope, and changes and improvements to the utility model will be possible without exceeding the concept and scope specified in the attached claims.
