Description
Technical field
The utility model belongs to the medical equipment field, particularly relates to a kind of isolated organ volume constant temperature measurement system of accurate measurement isolated organ volume.
Background technology
Liver transfer operation has become a kind of effective choice of treatment liver diseases in whole latter stage, acute FHF; Yet supplying the liver shortage is the subject matter that faces countries in the world present stages; Urgency in the face of liver patient in whole latter stage; Explore new organ obtain manner, guarantee that success rate of operation becomes the responsibility that the medical worker is duty-bound.Part liver transplant (mainly comprise Living Donor Liver Transplantation, split from the formula liver transfer operation) becomes the effective way that increases organ origin.In carrying out the part liver transplant, must degree of accuracy measure liver volume, obtain the real volume of liver and help to improve success rate of operation.
Present stage is mainly adopted drainage for the measurement of organ volume in the transfer operation process, and this method is put into isolated organ and filled with the container of preserving liquid, and through measure the volume calculation organ volume of overflowing liquid with measuring cup, this method error is bigger, complicated operation; Container can't guarantee the ideal temperature of Liver Allograft Preservation, therefore in measuring process, may cause the damage of tissue, and the measurement result systematic error is big, the effect of low precision image liver transplant.
The utility model content
The utility model provides a kind of isolated organ volume constant temperature measurement system of accurate measurement isolated organ volume in order to solve the problem that exists in the above-mentioned liver transplantation process.
The utility model is to address this problem the technical scheme of being taked to be:
The isolated organ volume constant temperature measurement system of the utility model; The measuring vessel that comprises inner splendid attire preservation liquid; The bottom of measuring vessel is provided with and makes the inner liquid circulation chamber that keeps constant temperature of measuring vessel, and the liquid circulation chamber is communicated with outside liquid coolant device for casting; The measuring vessel top is provided with and is used to survey the liquid level sensor that the interior liquid level of measuring vessel is raised height, and liquid level sensor is connected with data processing unit, and the outside surface of data processing unit is provided with display screen.
Described data processing unit is connected with power supply, and by power supply electric energy is provided; The right lower quadrant of data processing unit is provided with starting switch.
Described liquid level sensor is a high precision throw-in type liquid level sensor, and the sensor probe of this liquid level sensor front end is corrosion-resistant dismountable stainless steel probe.
Advantage and the good effect that the utlity model has are:
The liquid level information that the utility model is surveyed level sensor is sent to data processing unit through serial communication, calculates the volume that obtains to raise liquid, extrapolates the volume of isolated organ, passes through the volume of display screen display organization again; To the problem that cubing in the organ transfer operation process exists, accomplished the liver volume constant temperature measurement system that exsomatizes automatically, simplified process of measurement, improved measuring accuracy, reduced the tissue damage possibility.

Embodiment
Followingly the utility model is carried out detailed explanation with reference to accompanying drawing and embodiment.
Fig. 1 is the structural representation of the isolated organ volume constant temperature measurement system of the utility model.As shown in Figure 1, the isolated organ volume constant temperature measurement system of the utility model comprises that inside is equipped with the measuring vessel 7 and data processing unit 2 of preserving liquid.The bottom of measuring vessel 7 is provided with and makes the inner liquid circulation chamber 8 that keeps constant temperature of measuring vessel, and the both sides in liquid circulation chamber 8 are formed with liquid circulation inlet 10 and liquid circulation outlet 9 respectively.
Measuring vessel 7 tops are provided with and are used to survey the liquid level sensor 6 that the interior liquid level of measuring vessel is raised height; Liquid level sensor 6 is a high precision throw-in type liquid level sensor; The sensor probe 5 of this liquid level sensor front end is corrosion-resistant dismountable stainless steel probe; Realized that circuit separates with tested article, be convenient to the sterilization of measuring vessel and sensor.Liquid level sensor 6 is connected with data processing unit 2, and the liquid level data transmission that collects to data processing unit, is calculated the volume of isolated organ, on the display screen that is positioned at the data processing unit outside surface 3, shows.Data processing unit 2 is connected with power supply 1, and by power supply 1 electric energy is provided; The right lower quadrant of data processing unit is provided with starting switch 4.
Fig. 2 is the structural representation of the liquid coolant device for casting of the utility model.As shown in Figure 2, liquid coolant device for casting 11 is provided with liquid coolant inlet 12 and cooling liquid outlet 13.Liquid coolant inlet 12 is connected with the liquid circulation inlet 10 in liquid circulation chamber 8, and cooling liquid outlet 13 is connected with the liquid circulation outlet 9 in liquid circulation chamber 8.Perfusion liquid temperature in the liquid coolant device for casting can be set; According to the perfusion liquid temperature of setting; The liquid coolant device for casting will continue 0-4 ℃ constant temperature liquid coolant is injected the liquid circulation chamber of measuring vessel bottom; The liquid circulation chamber is connected through heat conductive silica gel with the interior preservation liquid of measuring vessel, and heat interchange takes place.Through the heat interchange of liquid circulation chamber and measuring vessel, realize the measuring vessel temperature being controlled between 0-4 ℃ for the measuring vessel temperature controlling, guarantee that in vitro tissue is in best the preservation in the environment in the measuring process.
When the isolated organ volume constant temperature measurement system of use the utility model is measured isolated organ; In measuring vessel, inject the initial liquid of preserving; Liquid level sensor detects the liquid level of this moment, sends data processing unit to, notes the height of this initial liquid level.Insert isolated organ (organ places the liquid level below fully); The liquid level position that record is raised once more; Data processing unit will calculate the distance that liquid level is elevated automatically, extrapolate the volume of organ by the container bottoms product to raise distance, shown the volume of in vitro tissue by display screen.
