technical field

The utility model belongs to the technical field of medical instruments, in particular to a puncture air pressure washer.

Background technique

At present, there are various types of irrigators on the market, with complicated structures, and the composition of their core components is basically the same. They are all equipped with containers for placing solutions, but they are large in size, inconvenient for patients to carry, and correspondingly increase production costs. In addition, the irrigating solutions used in traditional irrigators are roughly divided into two categories: one needs to prepare the solution by itself, but the preparation process is troublesome; the other uses the solution in the medical infusion bag (bottle), but the mouth of the medical infusion bag (bottle) It is not easy to open, which makes the pouring process difficult, and increases the work difficulty of medical staff, and the pouring process is unsafe and hygienic, and the large container bottle is not easy to clean and disinfect after use.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in the figure, the puncture air pressure flushing device includes a puncture needle 3, a liquid inlet channel 13 and an air inlet channel 12 are arranged in the needle cavity of the puncture needle 3, and an air outlet 1 and one or more than one inlet ports are arranged at the needle tip of the puncture needle 3. The liquid port 2, the top of the liquid inlet passage 13 communicates with the liquid inlet 2, the top of the air inlet passage 12 communicates with the air outlet 1, the bottom of the air inlet passage 12 communicates with the corresponding air inlet 11 arranged on the lower part of the puncture needle 3, and the inlet The gas port 11 is connected to the gas source 6 through the gas source connecting pipe 5 ; the bottom of the liquid inlet channel 13 is connected to the flushing head 10 through the flushing connecting pipe 8 . The lower part of the puncture needle 3 is provided with a needle base 7, and the puncture needle 3 and the needle base 7 are integrally formed. parts hard. The air inlet 11 is connected with the air source connecting pipe 5 through the one-way valve 4, and the one-way valve 4 is used for one-way air intake. A stop valve 9 is arranged on the flushing connecting pipe 8, and the stop valve 9 can adjust the size of the liquid outlet. The needle tip of the puncture needle 3 is provided with two, three or four liquid inlets 2 uniformly distributed in a circular shape. The air source 6 can be an air pump, a manually squeezed ball or other air intake devices.

When in use, insert the needle tip of the puncture needle 3 into the liquid packaging bag, turn on the air source 6, and the air enters the liquid packaging bag from the air outlet 1 through the air source connecting pipe 5, the one-way valve 4, the air inlet 11, and the air inlet channel 12 Inside, under the action of air pressure, the liquid in the liquid packaging bag enters the flushing connection pipe 8 from the liquid inlet 2 through the liquid inlet channel 13, and then sprays out from the flushing head 10 for flushing.
