Description

Technical Field

[0001] The utility model relates to the technical field of microwaves, in particular to a negative pressure microwave therapeutic head. Background Art

[0002] Hyperhidrosis, or excessive sweating, is a common condition that can cause excessive sweating in the armpits, face, or feet. Sweating can lead to physical side effects, including dehydration and infection, as well as emotional side effects, such as embarrassment. Currently, multiple treatments for hyperhidrosis are known, including medications, antiperspirants, botulinum toxin, and microwave ablation.

[0003] In the invention patent with application number "201280048302.5" and title "Applicator and tissue interface module for dermatological equipment", a tissue interface module is disclosed, which has an applicator chamber located on the proximal side of the tissue interface module and a tissue acquisition chamber located on the distal side of the tissue interface module. The applicator chamber may include: an opening suitable for receiving an applicator; an attachment mechanism positioned in the applicator chamber and suitable for attaching the tissue interface module to the applicator; a sealing member positioned at the proximal side of the applicator chamber; and a vacuum interface positioned at the proximal side of the applicator chamber and suitable for receiving a vacuum inlet positioned on the distal end of the applicator.

[0004] In this invention patent, the tissue interface module is equivalent to a microwave treatment head, and the applicator is equivalent to a microwave treatment handle. When the tissue interface module is connected to the applicator for use, the proximal sealing component of the applicator chamber needs to be sealed with the applicator so that the applicator chamber, the tissue acquisition chamber and the airflow path are all in a negative pressure balance state. That is to say, basically most of the space in the tissue interface module needs to be in a negative pressure state, which places extremely high requirements on the sealing design and sealing conditions of the internal structure of the tissue interface module, and will also increase the structural complexity and design and manufacturing costs of the tissue interface module.

DETAILED DESCRIPTION

[0023] The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not necessary. In addition, in order to simplify the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0024] In addition, in the present utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present utility model. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0025] See also Figures 1 to 3 As shown, the negative pressure microwave therapy head of the embodiment of the utility model is an auxiliary treatment accessory of the microwave therapy equipment. The negative pressure microwave therapy head 100 is used to contact the tissue in the treatment area and lift the tissue in the treatment area to facilitate the microwave therapy handle 200 to output microwave energy to act on the treatment area.

[0026] like Figure 1 As shown, the negative pressure microwave therapy head 100 and the microwave therapy handle 200 are detachably connected and used as disposable consumables.

[0027] Combination Figure 2 and Figure 3 As shown, the negative pressure microwave therapy head 100 includes a shell 1 and a cover 2. The shell 1 is provided with a receiving chamber 11 for receiving the waveguide antenna and an adsorption chamber 12 for forming a negative pressure adsorption treatment area tissue. The receiving chamber 11 and the adsorption chamber 12 are separated by a rigid film 3. A through hole 18 may be provided between the receiving chamber 11 and the adsorption chamber 12, and the rigid film 3 is disposed on the through hole 18 to simplify the internal structure of the shell 1.

[0028] A negative pressure communication chamber 13 is also provided in the shell 1 , and the negative pressure communication chamber 13 is located outside the receiving chamber 11 . A negative pressure air inlet 14 is provided on the side wall between the negative pressure communication chamber 13 and the adsorption chamber 12 , connecting the negative pressure communication chamber 13 with the adsorption chamber 12 .

[0029] The housing 1 is provided with an opening that is connected to the negative pressure connection chamber 13 on one side close to the microwave treatment handle 200, and the cover body 2 is covered on the opening. The cover body 2 is provided with a negative pressure connection device, which includes a boss 21 extending outward on the cover body 2, and a negative pressure channel 22 connected to the negative pressure connection chamber 13 is provided in the boss 21. The negative pressure channel 22 is provided with a sealing sleeve 23 for sleeve connection with the negative pressure tube in the microwave treatment handle 200. The sealing sleeve 23 can be made of a flexible material with good sealing properties such as silicone, rubber, silicone resin, etc. When the negative pressure tube in the microwave treatment handle 200 is inserted into the sealing sleeve 23, the sealing sleeve 23 can enable the negative pressure tube to form a negative pressure connection with the negative pressure connection chamber 13.

[0030] Since the negative pressure connecting chamber 13 is connected to the adsorption chamber 12 through the negative pressure air inlet 14, the negative pressure connecting device on the cover body 2 is provided with a negative pressure channel 22 connected to the negative pressure connecting chamber 13. Thus, the adsorption chamber 12, the negative pressure connecting chamber 13 and the negative pressure channel 22 form a negative pressure airflow path to suck the tissue into the adsorption chamber 12.

[0031] Therefore, compared with the prior art, under the same condition of sucking tissue into the adsorption chamber 12, it is not necessary to seal the receiving chamber 11 to keep the receiving chamber 11 in a negative pressure state. This greatly simplifies the sealing design of the internal structure of the negative pressure microwave therapy head 100, reduces the requirements for sealing conditions, and reduces the structural complexity and design and manufacturing costs of the negative pressure microwave therapy head 100.

[0032] A hydrophobic breathable membrane 24 is also provided in the negative pressure channel 22, and the hydrophobic breathable membrane 24 is located on the inner side of the sealing sleeve 23. The hydrophobic breathable membrane 24 has the property of being permeable to gas but not to liquid, and can filter the air flowing through the negative pressure airflow path to prevent blood, sweat, and other foreign matter such as liquid or tissue from being sucked into the microwave treatment handle 200.

[0033] A plurality of connectors 15 for connecting to the microwave treatment handle 200 are disposed on the side wall of the housing 1 away from the adsorption chamber 12 . The connectors 15 are provided with hooks 16 . The outer side walls of the connectors 15 are also provided with buttons 17 protruding outwards.

[0034] A rigid skirt plate 4 is also connected to the end surface of the adsorption port 121 of the housing 1 near the adsorption chamber 12. A mounting groove is provided on the end surface of the adsorption port 121. A connecting block 41 matching the mounting groove is provided on the rigid skirt plate 4. The connecting block 41 is correspondingly inserted into the mounting groove to connect the rigid skirt plate 4 to the housing 1. The side wall of the rigid skirt plate 4 is inclined from one end near the adsorption port 121 to one end away from the adsorption port 121 to form a trumpet-shaped expansion. The rigid skirt plate 4 can increase the contact range between the adsorption chamber 12 and the tissue in the treatment area, which is more conducive to sucking the tissue in the treatment area into the adsorption chamber 12.

[0035] The side wall of the adsorption chamber 12 is provided with an inclined wall 122 inclined toward the negative pressure air inlet 14, and the inclined wall 122 is connected to the negative pressure air inlet 14 to form a buffer zone 123 at the negative pressure air inlet 14. The buffer zone 123 can prevent the tissue sucked into the adsorption chamber 12 from blocking the negative pressure air inlet 14. In addition, the negative pressure air inlet 14 is located close to the receiving chamber 12, which can also avoid the negative pressure air inlet 14 from being blocked by the sucked tissue.

[0036] In addition, a foreign body receiving portion 131 is provided in the negative pressure communication chamber 13, and the foreign body receiving portion 131 is located below the negative pressure air inlet. The foreign body receiving portion 131 can receive foreign bodies such as blood, sweat, and other liquids or tissues that enter the negative pressure communication chamber 13 and are isolated by the hydrophobic breathable membrane 24.

[0037] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0038] The negative pressure microwave therapy head of the utility model is provided with an adsorption chamber and a negative pressure connecting chamber on the shell, a negative pressure air inlet is provided on the side wall between the negative pressure connecting chamber and the adsorption chamber, the negative pressure connecting chamber is connected with the adsorption chamber, and a negative pressure connecting device is provided on the cover body, the negative pressure connecting device is provided with a negative pressure channel connected with the negative pressure connecting chamber. Thus, the adsorption chamber, the negative pressure connecting chamber and the negative pressure channel form a negative pressure airflow path to suck the tissue into the adsorption chamber.

[0039] Therefore, under the same condition of sucking tissue into the adsorption chamber, it is not necessary to seal the receiving chamber to keep the receiving chamber in a negative pressure state, thereby greatly simplifying the sealing design of the internal structure of the negative pressure microwave therapy head, reducing the requirements for sealing conditions, and reducing the structural complexity and design and manufacturing costs of the negative pressure microwave therapy head.

[0040] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
