Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to the improvement of the structure of the airbag inflation / deflation pipeline controller in various types of braces containing airbags. Background Technology

[0002] Existing braces used to provide support or orthotics for injured limbs or necks often use multiple airbags. By adjusting the inflation and deflation of each airbag, a precise fit can be achieved. In order to enable one air pump to inflate multiple airbags individually, a brace is generally equipped with a brace airbag inflation and deflation line controller.

[0003] Currently, the inflation and deflation of airbags in braces are manually adjusted by the air pumps integrated into the braces. This type of inflation and deflation adjustment structure is mainly suitable for user operation, where users adjust the air pressure of each airbag by feel. Medical staff can only determine the airbag inflation pressure by asking the user for their feedback. For example, the airbag inflation and deflation pipeline controller of the applicant's application number CN 202421567406.3 filed on July 4, 2024, has been found in actual use to be ineffective in some users in adjusting the air pressure of each airbag to the appropriate level. Excessive inflation pressure may lead to poor blood circulation in the legs, while insufficient inflation pressure may not provide adequate support and protection. The operation process is also inefficient for medical staff. Utility Model Content

[0004] In summary, the purpose of this utility model is to solve the technical shortcomings of existing braces, such as the difficulty for users to control the inflation pressure and the low efficiency of medical staff in the operation process of inflating the brace airbag, and to propose a brace airbag inflation and deflation pipeline controller.

[0005] To address the technical shortcomings of this utility model, the adopted technical solution is as follows: a brace airbag inflation / deflation pipeline controller, comprising a base, a manual air pump connector connected to a manual air pump on the base, and two or more brace airbag connectors; an air path switching block is slidably disposed in the base between the manual air pump connector and the brace airbag connector, the air path switching block having an air guide channel that switches the manual air pump connector and one of the brace airbag connectors to be individually connected as the air path switching block slides; the base also has a face shell that prevents the air path switching block from detaching from the base; characterized in that: each brace airbag connector is connected to an external air source inflation pipe through three channels, and the air inlet end of each external air source inflation pipe is provided with a one-way air inlet valve core; the air inlet end of each external air source inflation pipe is fixedly installed on the face shell.

[0006] The technical solutions that further define this utility model include:

[0007] Each faceplate has a recessed air source interface groove, and the air inlet ends of each external air source inflation pipe are embedded and fixed in the air source interface groove side by side.

[0008] An external air source connector slot is provided on the side wall of the air source interface groove.

[0009] The side wall of the air source interface groove is provided with a foolproof positioning groove.

[0010] The gas source interface groove is equipped with a soft rubber protective cover.

[0011] The air path switching block has a three-inlet and one-outlet air path. The air path switching block has three equidistant air inlets on the side corresponding to the manual air pump connector, and one air outlet on the side corresponding to the brace airbag connector.

[0012] The air passage in the air path switching block is a one-in-one-out passage. The base is provided with a one-in-three-out air supply passage between the manual air pump connector and the sliding contact side of the air path switching block. The air inlet of the air supply passage is connected to the manual air pump connector. The three air outlets of the air supply passage correspond one-to-one with the three support airbag connectors separated by the air path switching block.

[0013] The beneficial effects of this utility model are as follows: Without affecting the original manual inflation / deflation structure of the airbags, this utility model adds external air source inflation pipes to the airbag inflation / deflation pipeline controller, which are connected to each airbag. Each external air source inflation pipe has a one-way air valve core at its air inlet end. By bringing together the air inlets of each external air source inflation pipe, it can be connected to an external air source for automatic inflation. The external air source control system can accurately and efficiently control the inflation to the preset pressure value, making it convenient and quick to use. Attached Figure Description

[0018] The structure of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0019] Reference Figures 1 to 4As shown in the figure, the brace airbag inflation / deflation pipeline controller disclosed in this utility model includes a base 1, a manual air pump connector 2 connected to a manual air pump on the base 1, and two or more brace airbag connectors 3; the figure uses three brace airbag connectors 3 as an example for illustration. In specific applications, each brace airbag connector 3 is independently connected to one brace airbag on the brace; an air path switching block 4 is slidably provided in the base 1 between the manual air pump connector 2 and the brace airbag connectors 3, and a face shell 5 is also provided on the base 1 to prevent the air path switching block 4 from detaching from the base; the function of the air path switching block 4 is to allow the manual air pump to be connected one-to-one with each brace airbag for inflation / deflation operations. Of course, in specific implementation, the air path switching block 4 can also be switched to a position where the manual air pump is not connected to any brace airbag, that is, to switch to the 0 position after the inflation / deflation operation is completed.

[0020] The specific structure can be as follows: the air path switching block 4 is provided with an air guide channel that switches the manual air pump connector and one of the brace airbag connectors to be connected separately as the air path switching block slides; and the structure of the air guide channel can adopt various structures, in the following two ways:

[0021] The first type: The air path switching block 4 has a three-inlet and one-outlet air path. The air path switching block 4 has three equidistant air inlets on the side corresponding to the manual air pump connector 2, and one air outlet on the side corresponding to the brace airbag connector 3. That is, when the air path switching block 4 slides between different positions, one of the three air inlets in the air path switching block 4 is always connected to the manual air pump connector 2, while the air outlet in the air path switching block 4 is only connected to one of the brace airbag connectors 3.

[0022] The second type: that is Figure 4 The structure shown in the diagram features a single-inlet, single-outlet air channel in the air path switching block 4. The base 1 has a single-inlet, three-outlet air supply channel located between the manual air pump connector 2 and the sliding contact side of the air path switching block 4. The air inlet of the supply channel communicates with the manual air pump connector 2, and the three outlets of the supply channel correspond one-to-one with the three support airbag connectors 3, separated by the air path switching block 4. That is, when the air path switching block 4 slides between different positions, only one of the three outlets of the supply channel in the single-inlet, single-outlet air path of the air path switching block 4 is connected to one support airbag connector 3; the other support airbag connectors 3 are sealed by the side wall of the air path switching block 4. The position adjustment and positioning structure between the air path switching block 4 and the base 1, and the sealing structure between the two outlets of the air path switching block 4 and the support airbag connectors 3 and the three outlets of the supply channel, are not the main inventive points of this case and have been disclosed in prior patent applications; therefore, they will not be described in detail here.

[0023] The main inventive point of this utility model is that each airbag connector 3 of the support is connected to an external air source inflation pipe 6 through three channels, and the air inlet end of each external air source inflation pipe 6 is provided with a one-way air inlet valve core; the air inlet end of each external air source inflation pipe 6 is fixedly installed on the face shell 5. Specifically, each face shell 5 is provided with a concave air source interface groove 51, and the air inlet ends of each external air source inflation pipe are inserted side by side into the air source interface groove 51. After the external air source connector is inserted into the air source interface groove 51, it can be connected to three external air source inflation pipes 6 at the same time, which can inflate three support airbags. When the user needs to deflate each support airbag during use, the original manual inflation / deflation structure is used to deflate it.

[0024] To ensure stable insertion of the external air source connector into the air source interface groove 51, an external air source connector locking groove is provided on the side wall of the air source interface groove 51. A foolproof positioning groove is also provided on the side wall of the air source interface groove 51. This means that each support airbag can be inflated to different pressure values ​​according to the system's prediction of the external air source.

[0025] In order to protect the air inlet end of each external air source inflation pipe 6 from dust, the air source interface groove is provided with a soft rubber protective cover 7.

[0026] This invention adds an automatic inflation structure that is convenient and quick for medical staff to use, without changing the original manual inflation and deflation function of the brace. It is easy to use and has high inflation efficiency.
