Detailed Description

The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.

Examples

As shown in figures 1 and 2, the novel liquid inlet cavity for the hemofilter comprises a cavity body 1, and an inner cavity 17 is arranged inside the cavity body 1. Specifically, the cavity 1 is composed of a lower cavity 12 and an upper cavity 11, and the upper cavity 11 is covered on the lower cavity 12 and fixed through screws. In order to improve the sealing performance, a gasket is installed between the lower cavity 12 and the upper cavity 11.

The upper cavity 11 is provided with a first cannula interface 3, a second cannula interface 6, an air inlet 4 and an air outlet 5, and the first cannula interface 3, the second cannula interface 6, the air inlet 4 and the air outlet 5 are all communicated with the inner cavity 17.

In use, the first cannula hub 3 and the second cannula hub 6 each serve as an insertion port for an AB fluid cannula 16, as shown in FIG. 5. The air inlet 4 is connected to the air outlet of the dry powder barrel device of the equipment, and the air outlet of the dry powder barrel device discharges air into the inner cavity 17 and then discharges the air from the air outlet 5.

The first cannula interface 3 and the second cannula interface 6 are both obliquely arranged so as to facilitate the insertion of the AB liquid cannula into the inner cavity 17.

The lower cavity 12 is provided with a water inlet 8 and a water outlet 7, and the water inlet 8 and the water outlet 7 are also communicated with the inner cavity 17. The water inlet 8 is used for inputting liquid into the inner cavity 17, and the water outlet 7 is used for supplying water to other parts of the equipment and is connected with external parts through pipelines.

As shown in fig. 3 and 4, a second liquid level probe 10 is disposed on the cavity 1, and a detection end of the second liquid level probe 10 extends into the inner cavity 17. The second liquid level probe 10 detects the liquid level inside the inner cavity 17, when the liquid level reaches the detection end of the second liquid level probe 10, the second liquid level probe 10 sends a signal, and a control system of the device controls to stop water supply to the inner cavity 17.

As another preferable scheme, a first liquid level probe 9 is further disposed on the cavity 1, a detection end of the first liquid level probe 9 also extends into the inner cavity 17, and a detection end of the first liquid level probe 9 is higher than a detection end of the second liquid level probe 10.

The first level probe 9 can be used as a backup probe, i.e. if the second level probe 10 fails, it is detected by the first level probe 9; or for detecting the level of the cleaning liquid when the second liquid level probe 10 needs to be cleaned.

A reinforcing rib 14 is arranged between the upper cavity 11 and the lower cavity 12, the reinforcing rib 14 is positioned in the inner cavity 17, and the strength of the liquid inlet cavity is improved through the reinforcing rib 14. Both sides of the reinforcing rib 14 are provided with water baffles 13, and liquid is prevented from splashing to the probe in the liquid inlet process through the water baffles 13, so that misoperation is caused.

The cavity 1 is provided with an installation metal plate 2, and the whole liquid inlet cavity is installed in the hemofilter 15 through the installation metal plate 2, as shown in fig. 5.

As described above, the utility model discloses alright fine realization.
