Embodiment Construction

[0017] Combine below figure 1 and figure 2 The present invention will be described in detail, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0018] like figure 1 , figure 2 , the present invention provides an automatic constant pressure and pumpless gravity uterine distension device, which comprises a lifting mechanism 1 and a bracket 3 that can hang a uterine distention fluid bag 2, and the uterine distention fluid in the uterine distention fluid bag passes through an infusion tube 4 It is transported to the water inlet of the hysteroscope sheath, and then transported from the water inlet to the uterine cavity. A pressure sensor 5 is arranged near the water inlet of the infusion tube. The pressure sensor can be an existing miniature liquid film pressure sensor. The pressure in the infusion tube can be accurately measured, and the pressure sensor transmits the rea...

Abstract

The invention relates to medical appliances and particularly relates to an automatic-constant-pressure pump-free gravitational uterine distending device. The device comprises a lifting mechanism and abracket capable of suspending a uterine distending solution bag, wherein a uterine distending solution in the uterine distending solution bag is conveyed to a water inlet of a uteroscope sheath through a transfusion pipe and then is conveyed into a uterine cavity from the water inlet, a pressure sensor is arranged on the transfusion pipe close to the water inlet, detected real-time pressure information on the uterine distending solution is transmitted to a controller by the pressure sensor, and the controller controls the lifting mechanism to drive the bracket to rise and fall according to the real-time pressure information and preset pressure information, so as to maintain pressure of the uterine distending solution in the uterine cavity constant. According to the device, the conveying of the uterine distending solution is achieved through the sensor, the transfusion pipe, the controller and the like, and thus, employing of the existing pump type uterine distending machines is avoided; and gravitational uterine distending is employed, active pumping action on the uterine distending solution is absent, gas embolism induced by active pumping is avoided, complications cannot be caused, and the safety of surgery is improved greatly.

Description

technical field [0001] The invention relates to medical instruments, in particular to an automatic constant pressure pumpless gravity distension device. Background technique [0002] As one of the rapidly developing minimally invasive endoscopic techniques in modern gynecology, hysteroscopy has been widely used in the diagnosis and treatment of gynecological diseases in the past 20 years. In the hysteroscopy and treatment system, the dilatation machine is an indispensable device. Nowadays, hysteroscopic surgery is widely used in clinical practice. With the widening of surgical indications, the incidence of complications is gradually increasing. In recent years, deaths during hysteroscopy in my country have occurred frequently, and the serious complication of gas embolism has attracted widespread attention and attention of clinicians. Gas embolism is a fatal complication of hysteroscopic surgery. When the fluid in the fluid bag is used up by the dilatation machine and not r...
