Embodiment 1

[0029] Such as Figure 1-5 As shown, it is a schematic structural diagram of a skin expander provided by an embodiment of the present invention, including an expansion bag 1, a catheter 2, an injection valve 3 and a pressure detection device 4;

[0030] The catheter 2 is connected to the expansion bag 1, and is used for injecting expansion medium into the expansion bag 1;

[0031] The injection valve 3 is arranged on the catheter 2 for adjusting the flow rate and / or flow rate of the expansion medium;

[0032] The pressure detection device 4 includes a pressure detection circuit and a wireless detection device. The pressure detection circuit is arranged on the expansion bag 1 for detecting the expansion pressure of the expansion bag 1. The wireless detection device is connected to the pressure detection device. The detection circuit is wirelessly connected, and is used to obtain the pressure of dilating the balloon through the detection circuit.

[0033] In this embodiment, t...

Embodiment 2

[0038] In this embodiment, the expansion bag is composed of 6-14 layers of medical silica gel.

[0039] In this embodiment, the expansion sac is made of a multi-layer medical silicone structure, which can reduce the leakage during the expansion process of the expansion sac, so that the detection value of the pressure detection circuit is closer to the expansion pressure of the expansion sac on the skin tissue, which can Improve the detection accuracy, so that the injection flow and flow rate can be controlled more accurately, and the occurrence of complications can be reduced.

Embodiment 3

[0041] In this embodiment, the expansion capsule is a cube, an elongated body, a sphere or an ellipsoid; wherein, when the expansion capsule is a cube or an elongated body, the eight corners of the expansion capsule are rounded.

[0042] In this embodiment, in addition to the above-mentioned forms, the expansion capsule can also be set as an irregular capsule structure, and it should be noted that there are no sharp corners on the capsule structure. In particular, when the expansion sac is set in a cube or elongated style, its sharp corners should be rounded. It should be noted that the configuration of the dilation sac above is only a partial list of optional structural forms of the dilation sac, which can be set to a corresponding structural form according to production conditions or usage occasions, and the above embodiments are not intended to limit the present invention.

[0043] An embodiment of the present invention provides a skin dilator, wherein the expansion capsule...

Abstract

The invention relates to the technical field of medical apparatuses, in particular to a skin expander, a skin expanding system and a manufacturing method of the skin expander. The skin expander comprises an expanding bag, a duct, an injection valve and a pressure detecting device, wherein the duct is connected with the expanding bag, and is used for injecting an expanding medium to the expanding bag; the injection valve is arranged on the duct, and is used for adjusting the flow rate and / or the flow speed of the expanding medium; the pressure detecting device comprises a pressure detecting loop and a wireless detecting device; the pressure detecting loop is arranged on the expanding bag, and is used for detecting the expanding pressure of the expanding bag; and the wireless detecting device is in wireless connection with the detecting loop, and is used for obtaining the expanding pressure of the expanding bag through the detecting loop. According to the skin expander disclosed by the invention, the pressure detecting loop is arranged on the expanding bag, so that the expanding pressure can be better detected; and the pressure detecting device is arranged, so that wireless detectioncan be realized, the operation is convenient, and the pain of the patient is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a skin expander, a skin expander system and a manufacturing method thereof. Background technique [0002] Skin and soft tissue dilation, referred to as skin dilation, refers to implanting a skin and soft tissue dilator (referred to as dilator) under the normal skin soft tissue, and injecting liquid into the dilation sac through the injection valve to increase the capacity of the dilator so that it can be more effective on the surface skin. The soft tissue generates pressure, which acts locally through the expansion mechanism, causing the division and proliferation of tissue and epidermal cells and widening the cell gap, thereby increasing the skin area and obtaining repair materials that match the skin color, texture, structure, and hair with the recipient area . [0003] Existing skin dilators are usually equipped with a pressure detection device in the expansion bag, a...
