This invention relates to a device and method for aspirating hemorrhage from the stomach. The device includes a guide tube with an axially arranged suction chamber and an auxiliary chamber. One end of the suction chamber is fitted with a plug that communicates with it. The plug has several microporous rings penetrating its inner and outer circumference. The other end of the suction chamber is connected to a negative pressure unit. The auxiliary chamber is axially arranged on the wall of the suction chamber. One end of the auxiliary chamber extends into the end of the suction chamber and is connected to an impedance sensor. The other end is connected to an auxiliary flushing unit. The negative pressure unit and the auxiliary flushing unit are also electrically connected to a control module. The control module is electrically connected to the impedance sensor and the microporous rings and is used to trigger pulsed expansion of the microporous rings based on the impedance signal from the impedance sensor. Through pulsed expansion of the microporous rings, combined with reverse flushing by the auxiliary flushing unit, the device of this invention can achieve dual unblocking through both expansion and flushing, improving operational continuity.

The invention relates to the field of medical instruments, in particular to a multifunctional flushing device for hepatobiliary postoperative drainage, which comprises a flushing tube and a drainage tube, a flushing angle regulator is arranged at a liquid outlet of the flushing pipe and is used for changing the flushing angle; a transparent observation window is arranged on the drainage tube, a collector is arranged outside the observation window, and the collector is used for collecting visual information of drainage liquid in the drainage tube; the system further comprises a controller, the controller is used for analyzing hematocele and hydrops distribution in the hydrops cavity of the patient based on the visual information at all flushing angles, the flushing angle adjuster is adjusted according to the hematocele and hydrops distribution in the hydrops cavity of the patient, and the duration of flushing acting on hematocele and hydrops is prolonged. When flushing acts on the wound surface, the flushing angle is aligned with the upper portion of the wound surface. By the adoption of the technical scheme, the flushing position is adjusted according to the color of the drainage liquid after flushing, so that the flushing effect is improved.

The invention relates to a peritoneal dialysis catheter subcutaneous tunnel needle, which belongs to the technical field of medical instruments and comprises a puncture needle main body, an expandable balloon module, a light guide navigation unit and a negative pressure cooperative control module. Precise subcutaneous tunnel forming and dynamic hemostasis are achieved through the expandable balloon, the integrated light guide navigation unit recognizes blood vessels and nerves in real time, and a puncture path is guided to avoid obstacles; the hematocele is synchronously removed in combination with negative pressure suction, and tissue damage is avoided through pressure monitoring and a pressure relief mechanism. The instrument adopts double-channel handle integrated operation, supports single-hand controlled puncture, hemostasis and illumination switching, and is adaptive to open and minimally invasive surgery. According to the design, the limitation of traditional step-by-step operation is broken through, the operation efficiency and safety are improved, the risks of catheter displacement, leakage and infection are reduced, and a high-precision integrated solution is provided for implantation of the peritoneal dialysis catheter.

The invention discloses an air bag type fixing-free peritoneal drainage tube, and belongs to the technical field of peritoneal drainage. The drainage tube aims to solve the problems that an existing drainage tube is unstable in fixation, prone to blockage and infection, inconvenient in position adjustment and lack of buffer protection. According to the technical scheme, the device comprises a main drainage tube, a silica gel corrugated tube section I, an inflation tube, a limiting air bag, a carambola-shaped air bag, an auxiliary drainage tube, an annular air bag, a silica gel corrugated tube section II, a fixing ring, a matched disinfection assembly, an adjusting assembly and a braking assembly; silica gel corrugated tube sections are arranged in the main drainage tube and at one end, an annular air bag and a carambola-shaped air bag communicated with the annular air bag are arranged on the outer wall of the auxiliary drainage tube, a limiting air bag is arranged on the outer wall of the main drainage tube, and an inflation tube penetrates through the main drainage tube and is communicated with the air bag; a medicine storage cavity, an annular sponge, a dustproof ring and an inverted-cone-shaped liquid scraping lip are arranged in the fixing ring, and an adjusting assembly and a braking assembly are arranged on one side of the fixing ring. Double limiting, blocking prevention, active disinfection, accurate positioning and buffering protection are achieved, and the drainage device is mainly used for drainage of effusion, hematocele and pus in the abdominal cavity.

The invention belongs to the technical field of medical instruments, and particularly relates to a suction type spinal nerve stimulation line pressing device. The purpose is to integrate the negative pressure suction function and the wire pressing function into a single instrument, and the smoothness, efficiency and safety of surgical operation are remarkably improved. The problems that in an existing spinal nerve stimulation electrode implantation operation, due to the fact that errhysis blocks the view field, the process is tedious, an electrode wire floats and shifts, and the risk is high due to the fact that cooperative operation of two hands or multiple instruments is needed are solved. Specifically, the line pressing device can synchronously complete visual field clearness and guide line stabilization operation in the operation environment where hematocele is removed and the visual field is limited; besides, a vent hole which can be flexibly controlled by fingers is formed in the handle, the negative pressure of the suction head can be accurately adjusted in real time, and the potential risk that sensitive nervous tissues such as spinal cords are subjected to traction injury due to the fact that suction force of a traditional aspirator is too large and cannot be adjusted is avoided.

The utility model provides a hematocele blocking prevention device for drainage equipment, belongs to the technical field of medical instruments, and aims to solve the problems that due to the fact that an existing drainage tube is not internally provided with a self-cleaning device, when the drainage tube is blocked, blocking objects in the drainage tube cannot be effectively cleaned, and when a medical worker shakes up a bed head of a sickbed, the blocking objects cannot be effectively cleaned. The device comprises a drainage tube, the front end part of the drainage tube is provided with a first connecting tube, the rear end part of the drainage tube is fixedly provided with a second connecting tube, and the drainage tube is communicated with the first connecting tube and the second connecting tube. According to the drainage tube, under the condition that the interior of the drainage tube is blocked, the first control valve on the surface of the first connecting tube and the second control valve on the surface of the second connecting tube can be closed, then gas is pumped into the drainage tube from the gas inlet tube, and when the gas runs in the drainage tube, the drainage tube can be cleaned.
