Novel airwave double-connection air tap, and assembly applying air tap

Abstract

The invention provides a novel airwave double-connection air tap. The novel airwave double-connection air tap is characterized in that each air path channel of a first single-connection air tap is further provided with an air path shunting outlet, a connecting piece comprises second air path channels, an inlet of each second air path channel is in airtight connection with the corresponding air path shunting outlet of the first single-connection air tap, an outlet of each second air path channel is in airtight connection with a corresponding air path inlet of a second single-connection air tap,the number of the air path channels of the first single-connection air tap, the number of air path channels of the second single-connection air tap and the number of the second air path channels arekept consistent, and the number is at least two. The double-connection air tap can perfectly guarantee that the two single-connection air taps still keep corresponding air paths in order after the airpaths are shunted, the size of the whole double-connection air tap can be made small by controlling the shape of the connecting piece, the use requirements of users are met, and an assembly applyingthe novel airwave double-connection air tap can also have corresponding advantages.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a novel air wave double-connection gas nozzle and components using the gas nozzle. Background technique [0002] The peripheral air wave manometer is also called circulation pressure therapy instrument, gradient pressure therapy instrument, extremity circulation instrument or pressure antithrombotic pump, physical therapy. The air wave pressure therapy instrument mainly inflates and deflates the multi-cavity airbags sequentially and repeatedly to form a circulatory pressure on the limbs and tissues, and squeezes the limbs from the distal end to the proximal end of the limbs in an even, orderly and appropriate manner to promote blood circulation. It can improve the flow of lymph and improve microcirculation, accelerate the return of tissue fluid in limbs, help prevent the formation of thrombus and limb edema, and can directly or indirectly treat many diseases related to blood lymp...

AI Technical Summary

Problems solved by technology

[0004] 1. Directly connect the airbag through the airway tube. Since the airway tube is mostly made of rubber or other soft materials, due to frequent use, problems such as uneven pressure control and unsmooth air outlet are prone to occur, and the airway tube is prone to cracking. , breakage, and cannot meet the needs of more than one user to use together, and in the process of use, if the user needs to quickly deflate the airbag, the T-shaped plug-in device needs to be unplugged, and the next time it is used Plug it in again, if there are too many airbags that need to be deflated, it will undoubtedly be very inconvenient,

[0005] 2. After improving 1, the airbag is connected through a single-connection air nozzle. Although this method can relieve the airway to a certain extent, it can also be quickly deflated by disconnecting the air nozzle. However, due to the single-connection airbag The mouth can only conduct air through one airway, which is still prone to cracking and damage of the airway, and cannot meet the needs of more than one user to use together

[0006] 3. After further improvement to 2, the airbags are connected through multiple "Y-shaped" double-connected air nozzles. Although this method can quickly deflate the air by disconnecting the air nozzles, it can also be ventilated through dual channels. The method protects the airway to a certain extent, and can be separated by the "Y-shaped" double-connected air nozzle so that it can be used by multiple users. However, this "Y-shaped" double-connected air nozzle still has the following problems. Aspect: When more than one user is using it, it is difficult to ensure that the number of the sub-air hole corresponds to the number of the main air hole after the "Y-type" double-connected air nozzle pair diverts the air circuit; on the other hand, even if the sub-air hole and the main air hole are guaranteed The numbers of the air holes correspond to each other, because multiple "Y-type" double-connected air nozzles are required, which will lead to the excessive volume of the components using the air nozzle, which cannot meet the needs of users, thereby reducing the market competitiveness of the product. There is also a ventilation pipe that directly connects the air circuit through the "Y-shaped" double-connected air nozzle. The specific prior art has been recorded in a patent named a new type of air wave massager with the authorization number CN207804589 U
