Description
Technical Field
The utility model relates to the technical field of medical apparatus, concretely relates to palace mirror is with liquid collection and measurement system.
Background
The uterus swelling is carried out by using liquid such as normal saline or glucose injection in the hysteroscopic operation, when the hysteroscopic operation, particularly the electro-excision operation under the hysteroscope, a part of uterus swelling liquid enters the blood circulation of a patient through the wound surface of the uterine cavity operation due to the positive pressure state in the uterine cavity, and if excessive liquid enters the blood circulation of a human body, serious complications such as hyponatremia, water poisoning and the like occur to the human body, so that the life of the patient is endangered. The biggest factor influencing the safety of the hysteroscopy operation is that too much uterus swelling liquid enters the blood circulation of a human body in the hysteroscopy operation, so that the real-time monitoring and control of the amount of the uterus swelling liquid entering the blood circulation of the organism in the hysteroscopy operation is an important guarantee for ensuring the safety of the hysteroscopy operation. However, at present, there is no good solution for how to measure the uterus dilating liquid entering the human body, and most doctors in the operation determine the amount of the uterus dilating liquid to be used and the time for terminating the operation according to a visual method or an operation experience.
Theoretically, the total amount of uterus expanding liquid entering the blood circulation of the organism is determined by the following formula:
total amount of uterus swelling liquid in human body circulation, namely total amount of uterus swelling liquid in operation and total amount of uterus swelling liquid in vitro loss in operation
The traditional calculation method comprises the following steps:
1. the total amount of uterus swelling liquid used in the operation is as follows: the number of bottles used for uterine distention liquid in the statistical operation is calculated according to the number of bottles used for liquid per bottle of liquid (generally 500ml), and less than one bottle can only estimate the approximate liquid amount according to visual observation. In an actual operation, because the usage amount of the uterus swelling liquid is large, the situation that the usage amount of the liquid bottles is recorded incompletely exists, the situation that the calculated liquid amount is smaller than the actual usage amount due to the fact that the number of the liquid bottles is not recorded in a missing mode or the calculated liquid amount is larger than the actual usage amount due to the fact that the number of the liquid bottles is recorded excessively occurs, and the situation that the calculated liquid amount is larger than the actual usage amount due to the fact that a new bottle is replaced when a bottle of liquid is not completely used up in the operation process also;
2. total amount of uterine cavity fluid lost in vitro during operation: the method is always the most urgent and difficult problem to solve, and no special instrument is available for measuring the external loss of the uterine cavity fluid. The clinician estimates mainly using the following 2 methods: firstly, the fluid loss is estimated approximately according to the operation experience, the estimation can not be correctly carried out basically, and the result has no scientificity and accuracy; secondly, liquid lost in the dirt collecting barrel in the operation is poured into a collecting bottle with scales for measurement, the amount of the uterine swelling liquid lost on the operation drape is estimated visually, the external loss amount of the uterine swelling liquid is equal to the liquid amount in the dirt collecting barrel plus the target measurement lost on the operation drape, the liquid in the dirt collecting barrel is poured into the measuring bottle extremely inconveniently in the actual operation, the liquid amount lost on the operation drape cannot be estimated correctly by visual inspection, the result cannot be estimated correctly basically, and the result has no scientificity and accuracy. The method II is complex and inaccurate in calculation, so that the method I is basically used clinically at present and belongs to blind estimation basically.
Therefore, at present, no special detection instrument is used for scientifically and accurately monitoring the amount of the uterine distention liquid, statistics and analysis on the usage amount of the uterine distention liquid in the hysteroscopy operation cannot be carried out, so that serious operation complications are easily caused, and the life of a patient is threatened.
