Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a flushing and suction device for medical devices. Background Art

[0002] Medical irrigators are medical devices used in conjunction with flushing and suction machines. They are fully used in various surgeries and wound treatments. They are suitable for flushing clinical surgical wounds and wound surfaces, especially for cleaning various complex cavities and wall surfaces. They can effectively prevent infection, inflammation, and reduce wound non-healing phenomena; they are suitable for emergency debridement, debridement of old wounds, dressing change debridement in the burn department, and cleaning of vascular, neurogenic and pressure-induced ulcers, burns, trauma or surgical wounds. Medical irrigators can flush and suction at the same time, and can absorb and collect sewage in time while flushing. However, existing irrigators are inconvenient to install and disassemble, and inconvenient to carry; on the other hand, flushing and suction machines use a cavity for flushing and suction, which is not clean when used and is prone to cross infection. Traditional irrigators use pistons, which are underpowered and inconvenient to operate.

[0003] The medical flusher with application number CN201921482262.0 relates to the technical field of medical devices, comprising a flushing and suction gun body and a gun handle fixedly arranged at the bottom end of the flushing and suction gun body, one end of the flushing and suction gun body is fixedly arranged with an assembly seat, the inner side of the assembly seat is provided with a liquid suction tube loading port, one end of the liquid suction tube loading port is fixedly arranged with a liquid suction tube, one end of the liquid suction tube is provided with a filter tube, one end of the filter tube is fixedly arranged with a liquid suction head, the inner side of the filter tube is fixedly arranged with a threaded groove, the inner side of the filter tube is fixedly arranged with a primary filter layer, a filter tube, a primary filter layer, a secondary filter layer, a primary filter residue chamber, a secondary filter residue chamber, a primary filter hole and a secondary filter hole are provided, and the sucked dirty liquid can be subjected to multi-layer graded filtering treatment, and the particulate dirt attached to the dirty liquid can be fully filtered out, and more particulate dirt can be effectively prevented from entering the liquid suction tube cavity, so as to avoid blockage when too much particulate dirt accumulates in the liquid suction tube cavity.

[0004] However, the above-mentioned clinical irrigators, on the one hand, share the same cavity for flushing and suction, which easily leads to incomplete flushing and the risk of cross infection; on the other hand, the irrigators are complicated to connect and inconvenient to use, and there is no indication of whether to use manual or electric methods for flushing and suction. Summary of the invention

[0005] In order to solve the technical problems existing in the background technology, the present invention proposes a flushing and suction device for medical equipment. The flushing and suction chambers in the device are separated to avoid the risk of incomplete flushing and cross infection. In addition, the internal flushing of the device has its own motor and a built-in lithium battery for power supply, which is convenient for flushing and suction in various occasions.

[0006] The present invention is implemented as follows: a flushing and suction device for medical equipment, which consists of a flushing device, a suction device, and a device shell. The flushing device and the suction device are both installed inside the device shell. The flushing device includes a flushing catheter, a flushing battery, a flushing control switch and a flushing cavity. The suction device includes a suction catheter, a lithium battery, a suction control handle and a suction cavity. The head ends of the flushing device and the suction device are both installed in a double-lumen flushing and suction tube through the head end cap, and the tail ends of the flushing device and the suction device pass through the inner cavity to reach the shell tail of the device shell.

[0007] Furthermore, the device shell is divided into two halves, one on the left and one on the right. The two halves of the device shell are fixed into a whole by pins, and an inner cavity is formed inside the shell.

[0008] Furthermore, the shell includes a suction tube, a shell head, a shell tail, and a shell R angle. One end of the head end cap is connected to the suction tube, and the other end of the head end cap is connected to the connecting tube. A fixing sleeve is arranged at the front end of the shell head.

[0009] Furthermore, the connecting pipe is provided with an internal thread, the fixing sleeve is provided with an external thread, and the connecting pipe and the fixing sleeve are fixedly connected via the internal thread and the external thread.

[0010] Furthermore, the suction control handle is installed on the R angle of the shell, a handle fixing pin is set on the control handle, and a spring and a spring fixing pin are set inside the R angle; one end of the spring is connected to the handle fixing pin, and the other end of the spring is connected to the spring fixing pin.

[0011] Furthermore, the flushing cavity and the suction cavity are both installed in the suction tube.

[0012] Furthermore, the flushing control switch is divided into a primary flushing control button and a secondary flushing control button.

[0013] The advantages of a flushing and suction device for medical equipment provided by the present invention are: first, the flushing device and the suction device of the present invention are dual-chamber modes, which can solve the risk of cross infection caused by incomplete flushing, and at the same time separate the work to improve work efficiency; secondly, a motor and a lithium battery are arranged inside the device, which can facilitate the movement of the device to multiple occasions and is easy to carry; finally, the device is easy to install and disassemble through the outer shell and pins.
