Removable pump and negative pressure wound treatment system using same

The invention relates to a removable pump and a negative pressure wound treatment system using same. The removable pump comprises an upper module and a lower module. The upper module comprises a motor set and an elastic component. The lower module is connected with the lower part of the upper module by a removable conjunction structure and comprises a base, at least a suction check valve, at least a discharging check valve, a thin-film device and a lower elastic component. The base is provided with at least a suction passage and at least a discharging passage. The suction check valve and the discharging check valve are used for avoiding that waste liquor reflows to a wound or the base. The motor set can push the elastic component. And the mutual balance elastic of the lower elastic component and the upper elastic push the thin-film device pushes the thin-film device to form pump sucking power. The removable pump is matched with dressing and absorbing material and is applied in the negative ...

Auto-shunting microfluid apparatus

The invention discloses a microfluid device which can automatically split streams and comprises a main body, a microflow channel structure is arranged on the main body, when being injected from the upstream of the microflow channel structure, the microfluid flows towards the downstream of the microflow channel structure by the interaction of gravity, adsorbability and surface tension, and can fill a plurality of branch microflow channels which have certain length and are arranged at the downstream of the microflow channel structure, thereby achieving the aim of the automatic quantitative stream splitting of the microfluid for the detection or analysis of biomedicine.

Liquid collecting apparatus and method thereof

液体收集装置及其方法

The present invention is liquid collecting device and method by means of capillarity. The liquid collecting device includes one inlet, one outlet, one channel and several collectors. The inlet is connected to the collectors and the outlet via the channel, and the connection between the collectors and the channel locates between the inlet and the outlet. The liquid collecting method includes two steps: the first step of injecting liquid to the inlet to make liquid fill the collectors via capillarity and flow to the outlet; and the second step of injecting some pressured gas into the channel to extrude liquid from the collectors to corresponding detectors separately.
