Uterine cavity perfusate recovery and metering, tissue specimen collection and pollution protection device

Abstract

The invention provides a uterine cavity perfusate recovery and metering, tissue specimen collection and pollution protection device. The uterine cavity perfusate recovery and metering, tissue specimen collection and pollution protection device comprises a funnel body, an upper patch and a lower patch connected with the upper patch. An operation opening is formed in the connecting position of the upper patch and the lower patch, the front edge of the funnel body is connected to the lower part of the operation opening, and a neck tying belt is arranged on the rear edge of the funnel body. Gum is arranged on the sides, away from the funnel body, of the upper patch and the lower patch, and a liquid storage bag with scales is arranged at a ventage of the funnel body. According to the uterine cavity perfusate recovery and metering, tissue specimen collection and pollution protection device, the absorption amount of the perfusate can be accurately obtained, and potential serious risks can be found and treated in time, so that the occurrence of body fluid overload and / or dilution hyponatremia caused by the fact that a large amount of perfusate is absorbed is prevented; operative complications are reduced, and important clinical significance for reducing medical accidents and protecting the life safety of a patient is achieved; and moreover, specimens can be effectively collected, specimen loss is prevented, perfusate splashing pollution is prevented, and high popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device for recovering and measuring intrauterine perfusate, collecting tissue samples and protecting against pollution. Background technique [0002] Hysteroscopy is the most delicate and minimally invasive procedure in gynecological surgery. It has become an irreplaceable surgical method in the treatment of Dayton and others, but its development and promotion are limited by various complications. During routine hysteroscopic examination and electrosurgical surgery, the wound surface and endometrium will absorb the perfusate under the action of osmotic principle and water pressure. After the human body absorbs more than a certain amount of perfusate, the patient will experience "water intoxication". Electrolyte imbalance, pulmonary edema, cerebral edema, renal edema, heart failure, etc., and even death may occur. Accurate measurement of liquid uptake is therefore of...

AI Technical Summary

Problems solved by technology

[0003] At present, the input volume of uterine distension fluid (also known as intrauterine perfusion fluid) can be read through the scale of the uterine distension fluid bag; the key lies in the collection of the output volume. Some hospitals judge the status based on experience, and some hospitals place the collection under the operating bed. The uterine distention fluid flowing out of the uterine cavity flows directly into the collection bucket, but because the uterine cavity perfusate can only flow out from the relatively narrow cervix under the action of water pressure, splashing occurs from time to time. It is difficult for the collection barrel to collect the uterine distention fluid comprehensively and without omission, resulting in inaccurate measurement. There are reports of "water intoxication" in hospitals at all levels; The ground around the bed increases the chance of nosocomial infection

[0004] In addition, the tissue samples obtained during hysteroscopy need to be collected completely for pathological analysis. At present, there is no special collection device. The usual method is to place sterile gauze around the surgical site to hold the samples, and then pick them up a little bit after the operation. , tissue specimens are lost or washed away from time to time, which is time-consuming and labor-intensive
