Portable sinus tract deep-cavity wound adjustable negative pressure suction apparatus

Abstract

The invention discloses a portable sinus tract deep-cavity wound adjustable negative pressure suction apparatus, which comprises a drainage tube and a drainage suction tube, wherein a plurality of switch regulating clamps are arranged on the drainage suction tube; an exhaust port is formed in the top of the drainage bottle and a drainage port is arranged at the bottom of the drainage bottle; an LED diode cold-light lamp, a control switch and a battery are arranged on the lower surface of the drainage bottle; the LED diode cold-light lamp is connected to the battery by virtue of the control switch; a connecting strap is fixedly arranged at the top of the drainage bottle and a connecting strap is fixedly arranged at the bottom of the drainage bottle; a plug which is matched with the exhaust port and a plug which is matched with the drainage port are arranged at the tail ends of the connecting straps; and an annular fixing strap is additionally arranged on the upper end face of the drainage bottle. The negative pressure suction apparatus disclosed by the invention is good in regulating property and not easy in falloff, and the plug of the exhaust port is not easy to remove, so as to effectively avoid the leakage of drainage liquid; meanwhile, the drainage liquid is convenient to be poured, and the drainage bottle is convenient to be hung; and the suction apparatus can reduce medical material consumption, guarantee a normal operation even in the case of power failure, diminish the occupied area of an operating table and reduce an infection source.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a portable adjustable negative pressure suction device for sinus deep cavity wounds. Background technique [0002] Negative pressure suction is to create a negative pressure state at the suction end by a certain method, and use atmospheric pressure to squeeze the substance to be drained at the suction end to the inside of the suction end, so as to complete the effect of attracting the substance. [0003] At present, hospitals need to use negative pressure aspirators to remove the effusion in the stomach, chest cavity, and abdominal cavity, to remove blood exuded during surgery, or to remove sputum in the oral cavity and trachea. [0004] The negative pressure aspirator commonly used in traditional Chinese medicine hospital has the following disadvantages in the prior art: [0005] 1. The switch on the drainage tube regulator is a pulley-type adjustment switch on the comm...

Problems solved by technology

[0009] In view of this, the technical problem to be solved by the present invention is that the switch setting on the existing drainage tube regulator is loose and easy to fall off; the plug and suction device on the liquid or gas outlet are split structures, and the protruding outlet is easily Clothes are pulled and opened, causing drainage fluid to be exposed, contaminating patients and medical staff; the fixing hole on the suction device for hanging is small and short, making it difficult to fix, causing the drainage tube to be easily discounted and increasing the workload of nurses; there is no lighting device, and power failure Later, external lighting is used, occupying the operating plane and affecting the doctor's operation
