Description

Technical Field

[0001] The invention belongs to the technical field of medical devices and relates to an irrigation and suction machine, in particular to a multifunctional surgical irrigation and suction device. Background Art

[0002] A surgical irrigation and suction machine is a device used to flush wounds and wound surfaces and to absorb residual fluid during surgical operations.

[0003] The cleaning of the wound surface is completed by the peristaltic pump and flushing bag equipped on the surgical flushing machine. The peristaltic pump applies the liquid in the flushing bag to the part of the human body to be flushed to complete the flushing work. However, in colder seasons or when used in field hospitals, directly flushing the wound with a low-temperature flushing solution will increase the patient's pain and is not conducive to the patient's recovery.

[0004] In addition, if the surgical suction machine is used on patients with infectious diseases, while sucking out residual fluids through negative pressure, it will also suck out gases containing viruses and bacteria. If the sucked gases are directly discharged into the atmosphere without being treated, the air will be filled with viruses and bacteria, posing a threat to the health of people around them.

[0048] The earth pole body shell is a stainless steel one-piece structure, which includes an earth pole tube body, an end plate arranged at one end of the earth pole tube body, the outer diameter of the end plate is greater than or equal to the outer diameter of the earth pole tube body, a connecting boss for installing a connecting spring is arranged at the inner middle position of the end plate, and a flange structure with an outward flange is arranged at the other end of the earth pole tube body, and flange holes connected to the flange plate are arranged at intervals on the flange structure, and the air inlet and outlet are arranged at both ends of the tube body of the earth pole tube body. During specific assembly, a fastening clamp made of conductive material (such as stainless steel, etc.) is installed on the outside of the earth pole tube body, and the fastening nut of the fastening clamp is directly grounded or connected to the ground pole of the power supply; the power supply outputs an AC high-voltage signal, wherein the high-voltage pole is connected to the high-voltage pole rod through a wire, and the ground pole is directly grounded or connected to the earth pole body shell.

[0049] The insulating support frame is made of a material with good heat resistance, pressure resistance and insulation properties, such as polytetrafluoroethylene material. It consists of a disc support part 61 and a cylindrical insertion part 62. A cylindrical insertion part is coaxially arranged at the inner center position of the disc support part. The cylindrical insertion part is inserted into the end of the high-voltage pole tube. Air-passing notches are arranged at intervals on the outer edge of the disc support part, and a through hole for inserting the high-voltage pole is provided in the middle of the cylindrical insertion part.

[0050] The high-voltage pole is made of a conductive material that is as corrosion-resistant as possible, such as stainless steel. In order to facilitate assembly, it is designed as a two-stage structure, that is, it consists of a high-voltage pole body 50 and a high-voltage pole top connection rod body 57. The high-voltage pole body is installed on an insulating support frame. The high-voltage pole body is a structure with an external thread design, which is convenient for connecting the high-voltage pole sealing and fastening insulating nut, the high-voltage connection spring fastening nut and the high-voltage pole sealing and fastening nut; the high-voltage pole top connection rod body is composed of a top connection disk and a through rod horizontally arranged at the center position of the rear part of the top connection disk.

[0051] The two-stage high-voltage pole structure can realize the modular assembly of the sterilization device, that is, the high-voltage pole body is assembled with the insulating medium tube, the high-voltage pole tube, the high-voltage connecting spring, the insulating support frame, the high-voltage pole sealing and fastening insulating nut and the connecting spring to form a sterilization module. When the whole is assembled, the sterilization module is assembled in the ground pole body shell, and then the flange, the insulating spacer sleeve and the second high-voltage pole are assembled, and the second high-voltage pole is connected to the first high-voltage pole. At the same time, this two-stage structure is also convenient for adapting to ground pole body shells of different lengths to meet sterilization requirements.

Under the action of the alternating electric field (the frequency of the alternating electric field is 30K Hz, the electric field strength is 2200V / mm, and the airflow velocity is 3M / S), the air is sterilized and disinfected (when the grounding body shell is forcibly grounded and the high-voltage pole is connected to the high-voltage AC signal, an alternating electric field is formed in the disinfection air gap. When the external alternating current is greater than or equal to 2000V / mm, the air in the disinfection air gap will be ionized to generate plasma. If the gas in the disinfection air gap contains organisms such as bacteria and viruses, under the plasma state, the organism will react with the oxygen in the air to generate carbon dioxide and water, thereby achieving sterilization and disinfection, and the single disinfection rate can reach 99.99%), the sterilized air is discharged from the gas outlet and discharged from the positive pressure port of the vacuum pump along the negative pressure outlet pipeline.

[0054] 3. Flushing and suction control handle with one-hand control for starting and stopping flushing and suction 8

A peristaltic pump flushing control port is formed at the front end of the top installation channel. A peristaltic pump flushing control pipe, a flushing hard pipe 27 and a suction hard pipe 26 are installed in the three pipeline installation channels from top to bottom. The front end of the peristaltic pump flushing control pipe is flush with the end of the peristaltic pump flushing control port. A negative pressure suction control port connected to the suction hard pipe is provided at the bottom of the gripping handle. The negative pressure suction control port and the suction hard pipe are connected through a tee.

[0056] The flushing air control joint is connected to the air control interface through a pipeline 29, and the rear end of the air control interface is connected to the positive pressure pump through a pressure sensor, and the pressure sensor is connected to the peristaltic pump signal;

[0057] The flushing joint is connected with a flushing tube, and the negative pressure suction tube is connected with the negative pressure joint.

[0058] During operation, hold the handle with one hand. When flushing is required, use the thumb to block the flushing control port of the peristaltic pump. The pressure sensor senses the pressure changes in the flushing pipeline. When the pressure value exceeds the set threshold, it sends a signal to the peristaltic pump to start the flushing operation. When aspiration is required, press the index finger on the negative pressure suction control port, leaving only the tube opening at the front end of the aspiration tube, and the suction force increases. Therefore, the aspiration operation can be performed under the action of negative pressure.

[0059] 4. It has dual power supply modes of DC and AC to meet the needs of different usage environments

[0060] A battery 22 is also installed in the main body of the flushing and suction machine provided with a DC power supply, so as to realize the DC and AC dual power supply of the flushing and suction machine and meet the use requirements in different environments.
