Description

Technical Field

[0001] This invention relates to the field of combat wound care technology, specifically to a rinsing and disinfection device for combat wound care. Background Technology

[0002] Battle wound care is a series of measures and behaviors that provide emergency medical care, follow-up treatment and comprehensive care to wounded personnel in the context of war or armed conflict, with the aim of minimizing casualties and disabilities and improving survival rates and quality of rehabilitation.

However, conventional irrigation devices mostly only have positive pressure irrigation function.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

This separation mechanism effectively guarantees the independent operation of core medical operations and auxiliary support tasks. Therefore, when treating casualties in batches, the management of flushing liquid replenishment and the basic operation of the air filling equipment can be delegated to non-professional personnel.

This significantly improves the equipment's battlefield adaptability and logistical support efficiency.

[0045] Working principle:

[0046] In use, connect the mounting head 501 to a clean standard military water bottle 502, place the hollow needle 216 in purified water or insert it into a saline bag, unfold the foot pedal folding plate 505, and pull the piston column 514 up and down to make the pumping piston 513 slide up and down. When the pumping piston 513 slides upward, it draws air into the pump cylinder 507 through the suction check valve 510. When the pumping piston 513 slides downward, it pumps the air inside the pump cylinder 507 into the mounting head 501 and the standard military water bottle 502 through the delivery check valve 508. Due to the one-way conduction of the suction check valve 510 and the delivery check valve 508, the up and down pulling of the pumping piston 513 will continuously pump air into the mounting head 501 and the standard military water bottle 502, causing the air pressure inside the standard military water bottle 502 to increase. The air pressure inside the standard military water bottle 502 can be controlled by the display of the pressure gauge 504.

[0047] During rinsing, connect the rinsing connector 301 to one end of the connector 206, and move the positioning slot 107 to switch the conversion spindle 101 to the rinsing mode. At this time, the two ends of the rinsing conversion channel 102 are connected to the air inlet pipe 202 and the exhaust pipe 207 respectively. The rinsing bypass channel 103 is also connected to the liquid inlet pipe 203. Twist and adjust the size of the exhaust pressure regulating valve 503 to make the high-pressure air inside the standard military water bottle 502 spray out. When the air is sprayed out, it enters the interior of the air inlet pipe 202 along the air inlet hose 205. Then the air passes through the rinsing conversion channel 102 and enters the exhaust pipe 207. Then it is sprayed out at high speed from the nozzle 302. When the high-pressure airflow passes through the rinsing contraction tube 109, it will be compressed and accelerated, which will increase the negative pressure at the end of the rinsing contraction tube 109. This will cause pure water or saline to be drawn into the rinsing conversion channel 102 along the rinsing bypass channel 103, the liquid inlet pipe 203 and the liquid inlet hose 204 and mixed with the airflow. Then it will be sprayed out with the airflow, thus achieving rinsing.

[0048] During suction, connect the suction connector 401 to one end of the connector 206, and move the positioning slot 107 to switch the conversion spindle 101 to suction mode. At this time, one end of the suction bypass channel 105 is connected to the exhaust pipe 207, and one end of the suction conversion channel 104 is connected to the air inlet pipe 202. The liquid inlet pipe 203 is closed. Twist and adjust the size of the exhaust pressure regulating valve 503 to eject the high-pressure air inside the standard military water bottle 502. When the air is ejected, it enters the interior of the air inlet pipe 202 along the air inlet hose 205, and then passes through the suction conversion channel 104 into the suction exhaust port 115. The airflow passes through the suction filter 114 and the suction exhaust port 115 and is ejected at high speed. When the high-pressure airflow passes through the suction shrink tube 111, it will be compressed and accelerated, which will increase the negative pressure at the end of the conversion spindle 101. This will create a negative pressure suction effect at the end of the suction bypass channel 105, allowing the airflow to enter the suction bypass channel 105 for suction along the suction extension tube 402, suction connector 401, sponge filter block 404, and filter cartridge 403. This will allow foreign objects in the wound to be extracted through the suction effect and then intercepted by the sponge filter block 404, thus facilitating the cleaning of deep wounds.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
